Gamma Ray Penetration Of Lead essays

Gamma Ray Penetration Of Lead essays The amount of radiation that occurs to the matter depends on two things: what radiation is used. what material is used for absorption. There are three types of radiation; they are Alpha, Beta and Gamma. Gamma radiation has two types of radiation, nuclear which is dangerous and electromagnetic which is not dangerous. Gamma rays are the opposite of alpha particles in a way. They penetrate a long way into materials without being stopped. This means they are weakly ionising because they bend to pass through rather than colliding with atoms. Eventually they hit something and do damage. The only thing that block Gamma rays is thick lead and concrete. In the experiment I will be using lead. In 1896 Henri Becquerel was investigating materials, which glow when placed in an x-ray beam. Curious to find out if strong sunlight caused uranium salt to glow. It was clear that uranium salts emit penetrating radiation, which can blacken photographic film. More interested in x-rays, Becquerel passed the challenge of further investigations on to one of his students, Marie Curie. Within a few years, Marie Curie discovered other elements such as thorium, which are radioactive. One of these elements, radium, was found to be over 1 million time more radioactive than uranium. Photographic film can be used to detect radiation. Radiation was first discovered by accident when Henri Becquerel left some uranium on some photographic plates, which became fogged by it. These days photographic film is useful way of detecting radiation. Workers in the nuclear industry or those using x-ray equipment such as dentists and radiographers wear little blue badges which have a little bit of photographic film in them. The film is checked every now and then to see if it has become fogged too quickly, which would mean the person was getting to much radiation. The nature of radioactive radiation. Alpha radiation was s...

How To Use A Twitter Chat To Grow Your Audience

How To Use A Twitter Chat To Grow Your Audience Twitter has always been a quick and easy way to connect with other people and be informed.  You can publish your content and reach hundreds (even thousands) of people. Even better, unlike many other social networks, you can repost your original content several times to gain even more exposure. You can do more with Twitter than just share content, though. You can both  market your blog or business and make connections with top industry players from around the world. How do you do it? You get involved in Twitter chats. What Is A Twitter Chat? Youve probably seen a Twitter chat or two in your newsfeed. A Twitter chat is a conversation between a group of people on Twitter. To keep the conversation organized, a specific hashtag that fits the conversation is used on every tweet. For example, #SamllBizChat is a popular Twitter chat for small  businesses.  Everyone who participates will use that hashtag in their tweets, which makes a Twitter chat easy to find and follow. You can also follow a Twitter chat by using a website like TweetDeck  or Twubs. Finding a Twitter chat is fairly easy.  There are websites that have lists of Twitter chats, such as  Tweetchat,  Tweetreports. There is even  a  random Google doc  that has a ton of Twitter chats listed. You can also ask people if they participate in Twitter chats and which ones they like. Joining A Twitter Chat Joining a Twitter chat conversation is easy, once youve found one that youre interested in. As the tweets appear and questions are asked, hop right in and  answer a question. Thats all it takes! Dont forget to include the specific hashtag for the chat in all of your responses as you participate. Welcome! Thank you for joining us. Please remember on each tweet to use the hashtag #edchat Jerry Blumengarten (@cybraryman1) June 10, 2014 Most Twitter chats are  open, so feel free to participate. Its important that you are make comments that add to the conversation, though. Stay on topic and be respectful of the other participants.   Participating In A Twitter Chat The rules of participating in a Twitter chat vary depending on the type of Twitter chat you have joined. These different types of chats depend upon how they are moderated. Heavily Moderated A  heavily moderated Twitter chat will be in a question and answer format. The beginning of a twitter chat will begin with people introducing themselves. For example, if I was participating in #SportsPRchat then Id write, Hi, Im Krista and Im a senior @MSUM. I love everything PR related. So excited to chat with you all. #SportsPRchat The moderator will start a tweet with Q1, meaning Question 1. The proper response will start with A1, meaning Answer 1. There is no need to hit the reply button when you type your answer in Twitter. Just create your own tweet, start it with A1, and include the hashtag. That will make sure that your tweet is part of the conversation. You can reply to peoples answers if you have something to add or if you just like their answer. Q5: After the backlash online, was this a social media fail or an act of PR genius? The topic is still trending. (2/2) #SportsPRchat Pam Chvotkin (@reddusfoximus) June 4, 2014 A5. Epic fail team if they really wanted to keep name ! All they did was prove more people feel strong about changing it #SportsPRchat Ben Christly (@BenChristly) June 4, 2014 Lightly Moderated/Open A lightly moderated/open Twitter chat will be less structured.  Theyll usually start with a question or a topic from the moderator, and then its free rein. Theres more to a lightly moderated Twitter chat than just tweeting one answer. It is more like a natural conversation rather than a Q and A session. You can tweet your opinion without needing to start your tweet with A1 since no official question was asked. In an open Twitter chat, you are free to contribute to the conversation as it fits, which includes responding to what others have said.  If you like what they say, tell them. If you disagree, let them know. If you need advice relating to the topic, ask and people will respond. As always, be a respectful participant. #edchat Topic: With the hundreds of issues that effect teaching learning, what should be the primary focus for change in ed? Jerry Blumengarten (@cybraryman1) June 10, 2014 Twitter Chat Is A Marketing Tool Twitter chats are marketing tools, but they arent typical. They approach marketing in a direct manner and are highly conversational. A Twitter chat can be both business-to-business (because you are conversing with others in your niche) or business-to-community (because you are conversing with your audience). Here are a few benefits of a Twitter chat and ways to use it as a marketing tool. Connect and network in your niche using #TwitterChats.1. Twitter chat lets you interact with people. Twitter chats are all about interacting and networking with like-minded professionals in your niche as well as your audience.  They provide an opportunity to market your personal brand and blog, and educate yourself by staying on top of trends and changes that you should know about in your industry. If you want to build creditability and make new connections, you are going to have to respond and interact with people. It doesn’t take much. If you see a comment you agree with just reply and say, I agree! It could be as simple as that, letting them know you are interested. 2. Twitter chat promotes your blog. Twitter chats are a great opportunity to promote your blog. If you wrote a blog post about a specific topic and there just so happens to be a Twitter chat on that topic, then it would be a good idea to mention your post. Just make sure it is something that is valuable to the conversation.  If its a lightly moderated chat, some people may ask questions that your blog answers. Reach out and personally invite them to take a look at it. When promoting your blog in a Twitter chat, though, dont be overly aggressive. You wouldnt want to say A1. I wrote a blog post on this topic. Read it. Its important to build relationships and trust. Find a person who needs some advice, give them some advice and mention they can read more at the blog post you wrote about the topic. That shows you care about their concern and genuinely want to help them. 3. Twitter chat builds credibility. Honestly, you dont need to mention your blog too often. Just participate in a twitter chat and provide relevant and valuable information. Interact with other participants. If you are building relationships and providing valuable information, people will begin to trust you. Then when they find out you have a blog, they will be more likely to read it. They know the writer and they know the writer knows what theyre writing about. 4. Twitter chat is a good way to learn. Twitter chats can connect you with people that are in your profession from around the world.   It gives you an opportunity to learn from  people who are true experts in their field.  Stay up to date in your industry and keep up with current trends, technology, and best practices. A Twitter chat is a great way to stay relevant. You can also discuss things with people who have experienced things that you haven’t experienced. For example: people deciding whether or not to study abroad can read and interact with people in a Twitter chat dedicated to studying abroad on a budget.

Why strong economies should support countries weak economies Essay

Why strong economies should support countries weak economies - Essay Example The paper tells that aiding underdeveloped countries by the industrialized countries is a very noble character since human nature is protecting and helping others. It is therefore worth understanding that helping poor countries is an internationally common practice whose main motive is based on moral obligation. Aiding underdeveloped nations act as an additional resource that empowers countries to develop themselves economically by financing their own projects. A humanitarian concern is the main reason behind helping poor countries. Funds or any aid offered to an underdeveloped country by the industrialized nation may assist in carrying out very important projects and programs such as elimination or reduction of diseases and poverty. This is because most poor countries are not able to raise funds that can help them in undertaking such kind of programs. Aiding is important because ‘It’s a necessity in eradicating third world poverty’. Availability of cheap labor in the Asian and other colonized countries as well as slavery catapulted economic development of the developed countries. Also, for harmony and peaceful coexistence, industrialized nations should act responsibly by helping the poor countries. It should be noted that ‘it is a moral duty to help those less fortunate than you’. Assistance by the rich countries may also be accompanied with technological transfer particularly when the aid is technical in nature and this may be of great help in boosting the economic growth of the underdeveloped countries. Moreover, the aid may come with training and education that may be of great use in promoting various infrastructural and human developments that are useful in propagating economic growth. Indeed ‘aid helps train teachers, buy textbooks for school’. Issuing aids further help in promoting the relationship between the developed and underdeveloped countries. By supporting countries experiencing financial difficulties, the strong economies tend to exercise equality in various sectors such as education, clean water, and healthcare. Supporting education and healthcare programs may boost literacy and health levels thus enhancing harmony in global development and reduces diseases and infections which may perhaps spread to the rich countries if proper treatment is not taken. Even for countries that do not need aid ‘at the end of the day, it is a matter of life and death’. On the other hand, giving an aid may not be the best thing to do to underdeveloped countries because of several negative effects and intentions it has on the underdeveloped nations.

Theories of Nationalism and Ethnicity Essay Example | Topics and Well Written Essays - 3750 words

Theories of Nationalism and Ethnicity - Essay Example This is what they call the â€Å"Toyota Way†. Whatever characteristics it may carry, it must be systemic, truly lasting and valuable to them. Along this line, the main concern of this paper is the Japanese ethnicity prominent in the Japanese-based Toyota Motor Corporation (TMC). The intended framework is to scrutinize the uniqueness of the much researched management style_ the â€Å"Toyota Way† at the same time determine which sociological perspectives and paradigms that would apply to the characteristics of Toyota’s Japanese ethnicity as well as determine how it has given great impact to the success of TMC. This paper seeks to draw some answers to questions like has Japanese ethnicity posed more of a problem or an advantage to TMC? What techniques does TMC use on its people to be able to build and attain such reputation which won the confidence of the public to patronize TMC’s quality-made vehicles and services within a Western-dominated work area? What i s this Toyota Way? How does Japanese ethnicity affect the quality performance of TMC? This academic exercise would attempt to relate selected socio-ethnical principles to the established ethos or principles used by TMC as well as possibly draw out some answers whether these principles overlap, contradict or complement each other? It is then within these parameters that the discussion on this paper will revolve. On the other hand, the limitation of this paper will only be on the time frame used to feature actual conditions of TMC as this paper uses data and time series, specifically a year before to date or prior to the March 11, 2011 tsunami disaster and nuclear meltdown. Keywords: Toyota Way, Ethnicity, Ethnocentrism, Corporate culture Toyota Motor Corporation’s Domain Before interpolating the sociological perspectives of ethnicity to TMC’s management principles and to understand better the subject understudy, it is important to have knowledge first of Toyota Motor Co rporation, its corporate philosophy, values, vision, and how it operates. TMC’s domain belongs to the automotive industry and thus, its main product is the automobile. However, â€Å"TMC today has expanded its business to other non-automotive related business activities to include: community livelihood support, education, financial services, among others. Their stakeholders include: customers, business partners (dealers and suppliers), investors, consumers, nongovernmental organisations government, community, stockholders.†(â€Å"Toyota Company Overview†, 2011) A Window to Toyota Motor Corporation (TMC) Toyota’s Significant Achievements Through the years, â€Å"Toyota has repeatedly outperformed its competitors in quality, reliability, productivity, cost reduction, sales and market share growth, and market capitalization† (Spear, 2010). TMC, within its domain, has gained public confidence in the quality of its luxurious, economical and environmenta l-friendly vehicles and other hi-tech products it produced. It has also expanded to venture on enhanced advanced technology products like robotics, prototyped environment-friendly electric cabs; spearheaded activities that lessen carbon emission in the environment and in its other involvement related to its aspiration to actualize its corporate social responsibility. Not to forget, TMC has expanded also its non-automotive activities like community education and livelihood support packages as

In Shakespeares Macbeth various devices are used to present the weird sisters as integral to the plot Essay Example for Free

In Shakespeares Macbeth various devices are used to present the weird sisters as integral to the plot Essay In Shakespeares Macbeth various devices are used to present the weird sisters as integral to the plot. In a modern context, are they still plausible figures? So witherd and so wild in their attire, that look not like thinhabitants othearth, and yet are ont? This description of the three weird sisters given by Banquo on first setting eyes on them creates an illusion of hell like hags; decayed and disfigured creatures. They are unnatural: they seem to be women but are not. It is Banquo who thinks they are evil: What! Can the devil speak true? Macbeth does not. Macbeth is intrigued by the sisters and later tells Lady Macbeth that he burned in desire to question them further. Macbeth asks the witches to stay showing he is interested in their predictions; Stay, you imperfect speakers, tell me more. The sisters speak dangerous thoughts, the same perhaps already plaguing his mind. If their predictions were already thoughts in the back of Macbeths mind, then the sisters lack power over him at this point. By examining the first conversation he has with Lady Macbeth on first returning home from battle, And when goes hence, tomorrow as he purposes this could be seen as evidence of couple having discussed the downfall of Duncan on an earlier date. If this is true then the sisters could be seen as mere triggers; they release the fiery evil within Macbeth. The fact that the sisters are in the first scene of the play confirms that they are important characters and from what they say, When the hurlyburlys done, when the battles lost and won gives the impression they know what is going to pass in the rest of the play. They meet in foul weather and talk of thunder, lightening and the fog and filthy air, giving the audience a first impression that Macbeth is a dark, dangerous play in which the theme of evil is central. They embody a malign and demonic intelligence. Their information does tempt Macbeth-but it is crucial to remember: they do not invite him to murder Duncan or even suggest a thing. Information is morally neutral until human beings begin to interpret it. The three hags prophecy that Macbeth will be king, they make no inclination whatsoever how he will come about this regal title. A lingering question still remains; had Macbeth given thought to killing Duncan before, and if the sisters had not made their prophecy, would Macbeth have murdered Duncan that night at the castle? In fact this is an unanswerable question but at the same time also very crucial. For if the answer is yes, the sisters would no longer be integral to the plot but be there just for the means of a supernatural subplot. On the other hand taking it as is given in the play, the implications of this are that Macbeth relies wholly on the sisters to spur him on. Macbeth is not a fool he realises that the prophecies cannot be ill, cannot be good and the forecasts of the future must come at a cost. Later on though, Macbeth no doubt driven by the success of his murdering of Duncan, seems to forget the sisters haunt that none of woman born shall harm Macbeth and the movement of Birnam Wood. Banquos warning to Macbeth concerning the instruments of darkness might also be seen as prophetical; Macbeth is betrayed as a result of believing these truths, and he comes to realise this in his final confrontation with Macduff. As the play goes on Macbeth is mixing his conscious life with his subconscious and the weird sisters become like a drug for him; the more you get, the better you feel, the more you want. The weird sisters prophecies draw out the evil within Macbeth; everyone has the basis to be truly wicked but not all of us have the trigger to pull it off, most of us are too full of the milk of human kindness. Regarding Macbeth, the weird sisters were his trigger. The evil does not come from anywhere else other than human nature. The sisters have not completely managed to corrupt Macbeth though. Both before and after Duncans murder Macbeth shows signs that his own natural feelings are still present in his character and that the witches do not have total power over him. He is foul for the things that he has done but is somewhat fair as he still has a natural human conscience. Before the murder Macbeth thinks that it would be cruel to kill innocent Duncan: Besides, this Duncan hath borne his faculties so meek, Had I but died an hour before this chance I had lived a blessed time. His feelings about Duncans murder are very similar to those about Banquos murder although he only acted out the first himself. He is sick with worry and guilt about Banquos murder, so much so he is turned to near madness by the bloody ghost of Banquo haunting him. On stage, Shakespeare sought to make the Witches actable and recognisable to his audience.In Britain we either rationalise Witchcraft or mock it and we have the added problem of an audience having seen Macbeth a countless number of times, often in very unconvincing renditions of Double, double toil and trouble it has even become some what of a comic joke book. With hooked nosed women dressed in black with pointed hats chanting round a cauldron; not quite a depiction of three terrifying, blood curdling, residents of hell. Shakespeare himself had to make adjustments to keep up with stage fashion. Originally he had three devils in place of the weird sisters, but the theatrical currency of devils was already starting to devalue through overuse, and they were more likely to induce laughter than fear. James I who was on the throne when Macbeth was written, famously believed in witches, he even wrote the novel, Daemonologie on the subject. Yet, during the lifetime of the king, attitudes to stage witches shifted and they started down the same comic route as the devils before them. This might be why no one in the text of Macbeth uses the word witch. When Shakespeare wrote Macbeth, weird characters were deemed capable of prophecy. Macbeth makes the association when he asks why the sisters stop our way, with such prophetic greeting. The modern mind, though, hear the modern denotation of weird, which incidentally, is used to describe those bearded ladies who vanish into the air. Formerly, weird ladies; those who endowed prophetic powers, were presumed to have magical powers as well. Now, ladies who think they have magical powers are presumed to be weird or peculiar Therefore it is becoming increasingly more difficult to make a contemporary western materialistic audience believe in them. Directors struggle to think of new interpretations of how to represent them. Are they young or old, male or female, disfigured or beautiful? Or even to represent them with the appearance of normal human beings, for that in itself is probably the most frightening understanding. Robert Cohen, in his 1982 Colorado Shakespeare Festival production, cast three beautiful women as the witches. Dressed in topless gowns they seduced Macbeth into a life of crime and corruption; here the weird sisters were depicted as real women more psychic than supernatural. Perhaps they too like Macbeth had morality, but had all the goodness sucked away and the evil human nature was dragged out of them and they were left even more corrupt than Macbeth is, at least he has the next life; hell we assume, they have to spend eternity festering in this world. This of course would be going against Shakespeares description of them but in my opinion in order to create three plausible figures in a modern context it is essential to create three characters; if they do even have any character that will make todays critical and realistic mind really believe that they are looking upon true forces of evil, rather than three women in black cloaks chanting round a cauldron. Personally it would not be plausible in my mind that they would be able to take the evil out of a man, who could do such terrible deeds. Perhaps a modern interpretation might be that it is genetics which control the way people make decisions; for if a director were to stage a futuristic Macbeth with the weird sisters as genetic engineers controlling the future, this would gain the desired effect on the audience; pure fear. Also, at the same time keeping up with stage fashions, test tube babies; the idea of creating humans unnaturally. For all our scientific rationality, modern society still acknowledges that there are forces we cannot explain. Some people believe in supernatural phenomenon; ghosts witches, evil forces; others would explain everything as from within the human mind; for example Lady Macbeth who generates the evil is already within Macbeth, therefore are just plot devices, there to release it from him. Even though they cause no first hand evil themselves, they evil that they thus create by delivering their riddle like prophecies is integral to the tragedy of Macbeth and without them fair would not be foul and foul would not be fair.

Alien and Sedition Act :: essays research papers

You are back in the year 1798, the government has just passed a law saying what ever they do and create it will be the standard. You have no say or any comment on it, because frankly they just don’t care. You are now placed back in the year 2001, would it be possible to apply a law of such magnitude to our society today? I don’t think so. Our country is based upon individual rights, we are allowed to say what we feel, and do what we want. It is what has shaped our country into what it is today. The saying rubber makes things perfect is one such example. It is a pliable material and can be formed or molded into whatever shapes you need it be. Just as our nation is today, it is pliable to our society’s needs. The Alien and Sedition Act demolished this moral standard by passing 4 acts that deny the power of people.   Ã‚  Ã‚  Ã‚  Ã‚  The United States at this time was faced with such economic and political problems domestically. Such economic problems as a trade barrier created such turmoil. In the text it is described that Spain, England and France on conditions of trade by saying that â€Å"Immediately following the war, Britain, France, and Spain are all restricted from American trade with the colonial states.† Our nation was also faced with one such problem as debt. The wars and battles our great nation has gone through in the past has created such a debt at this point in time that is almost not comprehendible for any normal human. In order to regain a financial balance the federalist came up with 3 solutions. They created an executive cabinet made up of heads of departments and they created a Judiciary Act of 1789. The Judiciary Act allowed for laws to be declared unconstitutional and put power back at a National level instead of state.   Ã‚  Ã‚  Ã‚  Ã‚  Hamilton came up with 3 reports to also help out with the debt our nation was facing. His first report was upon Pubic Credit, it stated that the nation would consolidate the debt at a national and state level, paying off the debt in face value, and would shift the power to the National Government. In Hamilton’s second report, he continued to set apart and distinguish between lower class and the aristocracy of the nation. Hamilton accomplished his separation by instating the First Bank of the United States.

A Perspective on Water Crisis Essay

Global water crisis is one of the biggest problems that the world is facing. Freshwater resources are increasingly becoming scarce today and probably for the next decades. Less than one-half of 1% of all the water on the planet comprises the available fresh and clean water (Maude). Humans already used more than half of the world’s clean fresh water and by the year 2025 the consumption of freshwater will increase to three-quarters. Global water consumption becomes double every 20 years and if this trend continues, the supply of freshwater will not be enough for the demand of the world’s population by 2025. World Bank and World Heath Organization noted that there are about 2 billion people have no access to clean and safe water and about 1 billion people have no enough clean water to meet their daily water requirements. Depleted water resources are attributed to the intensive urbanization, deforestation, water diversion, industrial farming and population growth. As the world population increases, the consumption of accessible freshwater may grow six-fold (Maude). As a result of water crisis, lots of people suffer and die from water and sanitation related diseases such as diarrhea, cholera, dysentery, and hepatitis. Unfortunately, most of the poorest countries in the globe are the ones who are experiencing water shortage. Uganda is located at the Sub-Saharan Africa and is among the poorest countries around the globe. The country relies solely on agricultural industry however, less than half of the arable land is subject for cultivation. Large part of the land area (more or less 82%) of the country is arable, however more than 67% of the country has poor ferralitic soil which has nearly lost its mineral content due to prolonged weathering. Thus, proper soil management is needed for the soil to regain its lost nutrients. The economy of the country has a great potential, considering the potentials of its agriculture and natural resources. There is a great possibility that Uganda will recover from difficulties, most especially from poverty. However, due to some existing problems that the country is facing, it seems to be difficult for Uganda to escape from poverty. One of the biggest problems that the country is facing today is water crisis. Water crisis definitely affect the country as a whole contributes to Uganda’s poverty and worsen her current situation (Dauda, 2003). The country of Uganda is definitely endowed with water resources. About 18% of the total surface area of the country is covered with renewable water resources including lakes, rivers and wetlands. Approximately, it can supply an individual of Uganda with 2,800 m of water in a year (Dauda, 2003). These fresh water resources are considered as the essential resource for sustaining life, preserving the environment, uphold development and alleviating poverty in the country. It has direct impact the quality of life of Ugandans and their productivity as a whole. Water is very essential to Uganda since it plays an essential role in the production of sufficient supply of food for the country as well as supplying electric power all over the country. It is the key resource of the country’s agriculture, food processing and other agro-industries which provides employment to the people of Uganda. Aside from supporting Uganda’s agriculture and industry, water also provides electric power to the country. Indeed, it is the source of hydropower which is the country’s main resource of abundant and cheap electric power. The socio-economic development of the country depends solely on the energy produced from hydropower. Inadequate power supply cannot support Uganda’s large-scale manufacturing industries and agro-industries which may lead to low economic level of the country (National Water Development Report, 2005). The major freshwater resources of Uganda include rainfall, surface or open water and groundwater. Rainfall is the most vital source of freshwater of the country. The rainfall pattern in the country greatly influences the land use potential and consequently the population distribution. The rainfall pattern of Uganda is influenced by the local topography and the presence of Lake Victoria. Rainfall in Uganda tends to increase with altitude; meanwhile, rainfall is apt to decrease with the distance from the lake. High rainfall is noted on the central and western parts of Lake Victoria and over the mountain. Another factor that determines the occurrence of rainfall is the country’s season. The most stable rain season in Uganda is from the months of March to May; meanwhile, the reported variable rainy months in Uganda is from October to December (National Water Development Report, 2005). The major freshwater resources of Uganda are in the form of lakes and rivers. These open sources are often used for the supply of hydropower in the country. The major resources of hydropower in Uganda are the Nile River and Lake Victoria. Lake Victoria supports the fisheries industry of Uganda and provide water supply to the majority of people of Uganda. Indeed, the Lake is also supporting the agriculture industry along its shoreline (National Water Development Report, 2005). However, the Lake’s potential use for the future is now in question since it is experiencing dying up which leads to lower water levels. The available water left in Lake Victoria may not be enough to sustain the required hydroelectric power generation (Xinhua News Agency). Other water bodies include Kyoga, Albert, George, Edward, Ruizi, Katonga, Kafu, Mpologoma and Aswa (National Water Development Report, 2005). Some of these lakes, most especially those on the western and central part are also drying up due to drought which threatens the cattle industry in the area. Cattles have little access to water which may lead to lower production rate and low quality of Cattles (Xinhua News Agency). In addition to drought, the quality of surface water has been deteriorating with time. In most parts of the country, surface and ground water are already polluted due to increased urbanization and population as well as human activities such as poor agricultural practices, poor sanitation practices, industrial waste discharge, and mining activities (National Water Development Report, 2005). Aquifers, which can only be generated and recharged by endogenous precipitation, are also essential resource of freshwater in Uganda. It is the major source of water in rural, semi-arid and arid areas in the country. The occurrence of groundwater is highly dependent on the geologic formation in the country. Uganda is endowed with productive aquifers water; this can be attributed to the geology of Uganda which is dominated by crystalline Basement Complex of pre-Cambrian age. More than 90% of the country is underlie by different kinds of rocks which predominantly include granites, granitoid gneisses and gneisses. Ground water resources are generally found on the underground layer of unconsolidated materials such as weathered bedrock, silt and clay. This groundwater can only be extracted through wells. The highest yielding and productive groundwater can be found in weathered-fractured bedrock which has high permeability (National Water Development Report, 2005). In general, the groundwater of Uganda is in good and sound condition. There are no traces of toxic substances that may threaten the health of the people in Uganda. Moreover, these aquifers have significant amount of minerals such as aluminum, calcium, magnesium metal cations, chloride, iron, manganese and chromium that may not cause harm to the people of Uganda. Consequently, there are few parts of the country that are found to have high amounts of these minerals and have traces of high nitrate and chromium levels in some areas. Aside from high amount of minerals, it was also reported that some parts of the country have found to be positive in Coliform bacteria. Contamination of the aquifers is attributed to deterioration of the borehole casings, leaching of sewage wastes, weathering of aquifer environment as well as poor sanitation condition in the areas around the aquifers (National Water Development Report 2005). In general, the availability and preservation of water resources in Uganda solely relies on various environmental, sociological and cultural factors. The availability of freshwater resources depends on the distribution of water bodies on the country. It is known that freshwater resources in Uganda constitute a great part of the country. However, due to its uneven distribution and seasonality, availability of water is still a big problem on most parts of the country. Ugandans find it difficult to have an easy access to fresh and clean water. Women together with their young are spending so much time and energy on walking a mile-long way just to fetch water from areas with sufficient supply of clean water. The uneven distribution of water resources in the country also influences the agro-industry in the country. Cattle raisers tend to transfer from place to place just to find safe and sufficient water for the cattles. As a result, disease spread and transfer brought by the cattles becomes prevalent on various regions of the country (Xinhua News Agency). Meanwhile, uneven distribution of groundwater greatly influenced the accessibility of Ugandans to clean water. Regions endowed with productive groundwater are indeed rich in geological characteristics (National Water Development Report 2005). The occurrence of extreme weather conditions has a great effect on the availability and safety of water on the country. Heavy rains may cause to flooding and consequently may contaminate the water resources of the some regions in the country. Contaminated water may result to more serious problems such as disease outbreaks, epidemics and even death. Contaminated water is the key reason to the high and increasing mortality rate of Ugandans especially of infants (National Water Development Report 2005). It is reported that most number of mortality occurs on infants and this can be attributed to less accessibility to clean and safe water. Meanwhile, erratic rainfall and seasonality of the occurrence of rainfall in the country resulted to desertification of arable lands. These definitely affect several industries in the country especially those that greatly depend on water (i. e. agricultural industries) (Dauda, 2003). Some of the suspected major reasons of water resources deterioration in Uganda are rapid growth population, urbanization, industrialization, relentless environmental degradation and deforestation as well as pollution. High population density greatly influenced the availability of water resources in Uganda. The population of Uganda in 2007 is approximately 30. 9 million and more than half of it is comprised of infants. The country has an average annual growth rate of 3. 4% which is one of the highest growth rates in the globe. The demand for water relatively increased while the supply decreased with high population density. And as what the country is experiencing, there is no enough clean water for all. Increased population accompanied by urbanization and industrialization resulted to increased pollution and deforestation. Most of the land bodies are converted to industries which produces toxic wastes that pollute the environment especially water bodies. This contributes to the decreased supply of water in Uganda. Depleted water supply is also attributed to poor agricultural practices in the country such as cultivation, pastoral activities, and livestock practices. Poor sanitation is also identified as a possible cause of freshwater shortage in Uganda. Some of the land owners that cultivate their own lands seem to be unaware of environmentally sustainable practices. They have poor knowledge on these methods that they do any practices which may pollute their environment. These practices accompanied by poor sanitation will indeed bring negative effect on Uganda’s environment. Poor sanitation practices are among the factors that contribute to depleted water supply and water related diseases in Uganda. Fetching and purifying water are very labor intensive, considering the distance that Ugandans walk just to obtain clean and safe water. They often share and obtain polluted water from water resources where farm animals usually dwell. However, as an everyday routine, it became arduous to the people of Uganda to fetch water from distance places and to consume so much time purifying the water that they fetched. People tend to ignore the hazard that the contaminated water may bring them; they just drink the water as ease without purifying it. As a result, development of water related diseases became prevalent in Uganda (Dauda, 2003). Another major factor that leads to water shortage in Uganda is global warming. Majority of Uganda’s water table, especially the northern and northeastern part is dry due to global warming and environmental degradation (Dauda, 2003). Global warming may also contribute to the occurrence on the extreme weather condition in the country such as El Nino and La Nina. Moreover, these parts of the country are experiencing wide fluctuations in the availability of water between wet and dry seasons as well as variations in the onset of rainfall as a result of the extreme weather conditions (National Water Development Report 2005). Prolonged drought, which leads to drying up of significant water tables of Uganda, has also threatened the food security in the country. Due to prolonged drought, production of staple foods of Ugandans such as sorghum and millet relatively decreased (EuropaWorld). Just like any other country, Uganda is rich in traditions and belief. They value their culture so much it comes to a point that their beliefs and traditions hinder the possibility of development in their country. There are existing cultural norms that are related to the water bodies in Uganda. Some of the water bodies in Uganda are believed to have special healing powers for many diseases and supernatural dwellers as well. Moreover, these water bodies have potentials for many significant uses such as hydropower resource and irrigation for agricultural industries. However, due to close cultural attachment of people of Uganda to these water resources, the government found it difficult to create potential programs that will optimize the use of the water resources in the country (National Water Development Report 2005). Aside from various problems stated previously that have great impact on freshwater availability, Uganda’s neighboring regions seem to contribute on the water crisis that it is experiencing. Majority of Uganda’s freshwater resources have existing crossing frontiers which bound the country from maximizing its use on its own water resources within its territory. Though they have legal riparian rights to have a share on the water resources, these transboundaries definitely affect the socio-economic growth of the country since water is considered to be as the key player in the development of Uganda (Encounter Uganda Well Health). For one thing, these transboundaries serve as the main competitors of Uganda from the available water resources. People of Uganda have little access to large water resources since they are restricted to come across the boundary of another country. Moreover, these crossing frontiers not only prevent Uganda from optimizing its available freshwater resources but source of food and employment as well (National Water Development Report 2005). In order to unravel the existing problems in Uganda, its government decided to make some modifications on its various sectors, most especially the water sector. Several studies and situational analyses are conducted by the water sector that leads to preparation of comprehensive strategy of water sector and investment strategies. The government has anticipated many factors and they made it possible that the strategies may still be implemented on the sector up to 2015. The government has already started implementing some of the strategies and one of these is Sector Wide Approach to Planning (SWAP). SWAP requires all stakeholders to participate in the planning and implementation of the sector’s activities while optimizing benefits for all. The strategy has provided a regular budget on the programs that are made which is relatively different to the previous programs that the sector has made (National Water Development Report 2005). Another significant program that also aimed to promote sustainable management and development of water resources of the riparian regions is the Collaborative Partnership Program. The program is focused in improving the coordination of efforts of the different stakeholders. The program is also focused on harmonizing strategies and plans that involves sustainable management and development of the shared water resources. This makes Uganda very eager to have a close relationship with its neighboring regions. Uganda became enthusiastic with regard to making joint plan, management and development of the water resources that they shared. Uganda’s aim on making collaboration with her transboundaries is for all of them to obtain fair benefits from the water resources as well as to ensure that they will get sufficient supply of clean water. Fair utilization and consumption of shared water provide a high opportunity for sustainable use of resources as well as sustainable growth and development. Moreover, Uganda will be able to support its economic and social objectives through collaborating with its cross frontiers (National Water Development Report 2005). The riparian countries including Uganda will have comparable advantages from the equitable use of shared water. While building a close relationship with the riparian countries, the potentials of the existing industries in Uganda may be developed through collaboration with her neighboring regions. Advancement in its industries may lead to economic development of the country and in turn advancement on the quality of life and well being of its whole nation. Meanwhile, there are potential conflicts identified in the implementation of collaboration program between the riparian countries. Aside from the common objective that the riparian countries agreed on making the joint collaboration, these countries also have different interests which make a potential conflict between them. They made plans and implemented projects which do not take into consideration the wide coverage of the shared water resources. They do not anticipate the possible conflicts that may arise by implanting their plans. As a result, some of their individual plans for the development of their own countries are contradicting with the plans of other countries. Plans of other countries will not be possible if other countries’ plan will be allowed. Another issue that makes the joint program complicated is the mistrust among the cross frontiers. This issue seems to be unavoidable since the riparian countries have different objectives and interest in joining the joint program. They refuse to show their own data regarding the shared water resources as well as information of their plans and strategies. Since the riparian countries have no idea of the plans and programs of other riparian countries there are instances that the individual projects implemented are the same with other countries (National Water Development Report 2005). The last issue identified is the restoration of the environment. One of the minor objectives of the joint program is to conserve the environment; however, it is found to be difficult to implement their plans and projects while not taking into consideration the possible negative effect that it may bring to their environment. The main concern here is the methods of the activities and projects as well as the way these are conducted. Countries located on the downstream of the shared water resources are threatened by the possible effect of the activities that the upstream countries are conducting. Also due to mistrust, they are not guaranteed that the upstream countries are performing the activities in a proper way. It is essential that both the upstream and downstream countries will conduct their programs and projects in such a way that these programs will not affect that conservation of environment that they are promoting in the country. Through this little start, there will be a great possibility that their countries will surpass big problems such as water crisis and most of all poverty. References Barlow, Maude.

Palladium Facts - Periodic Table of the Elements

Palladium Facts - Periodic Table of the Elements Palladium  is a silvery-white metallic element with atomic number 46 and element symbol Pd. In daily life, its most often found in jewelry, dentistry, and catalytic converters for automobiles. Here is a collection of useful and interesting palladium facts: Essential Palladium Facts Atomic Number: 46 Symbol: Pd Atomic Weight: 106.42 Discovery: William Hyde Wollaston 1802 (England) Wollaston noted his discovery of the metal in 1802 and offered the purified element for sale in 1803, although there was some controversy regarding the discovery. Richard Chenevix believed Wollastons palladium to be a platinum-mercury alloy. Chenevixs palladium experiments earned him the 1803 Copley Medal, but its clear Wollaston did at least partially purify the element. He dissolved platinum order from South America in aqua regia, neutralized it with sodium hydroxide and precipitated out the platinum. Reacting the remaining material with mercuric cyanide formed palladium(II) cyanide, which was heated to yield the purified element. Electron Configuration: [Kr] 4d10 Word Origin: Palladium was named for the asteroid Pallas, which was discovered approximately the same time (1803). Pallas was the Greek goddess of wisdom. Properties: Palladium has a melting point of 1554 °C, boiling point of 2970 °C, specific gravity of 12.02 (20 °C), and valence of 2, 3, or 4. It is a steel-white metal which does not tarnish in air. Palladium has the lowest melting point and density of the platinum metals. Annealed palladium is soft and ductile, but it becomes much stronger and harder through coldworking. Palladium is attacked by nitric acid and sulfuric acid. At room temperature, the metal can absorb up to 900 times its own volume of hydrogen. Palladium can be beaten into leaf as thin as 1/250,000 of an inch. Uses: Hydrogen readily diffuses through heated palladium, so this method is often used to purify the gas. Finely divided palladium is used as a catalyst for hydrogenation and dehydrogenation reactions. Palladium is used as an alloying agent and for making jewelry and in dentistry. White gold is an alloy of gold which has been decolorized by the addition of palladium. The metal is also used to make surgical instruments, electrical contacts, professional transverse flutes, and watches. In photography, palladium is an alternative to silver, used in the platinotype printing process. Sources: Palladium is found with other metals of the platinum group and with nickel-copper deposits. The primary commercial sources are the Norilsk-Talnakh deposits in Siberia and the nickel-copper deposits of the Sudbury Basic in Ontario, Canada. Russia is the primary producer. It may be produced in a nuclear fission reactor from spent nuclear fuel. Health Effects: Palladium, like the other platinum group metals, is mostly inert in the body as a bulk metal. However, there are reports of contact dermatitis, particularly in persons allergic to nickel. This causes problems when palladium is used in jewelry or dentistry. In addition to these uses, environmental exposure to palladium comes from release by automotive catalytic converters, food, and workplace exposure. Soluble compounds of palladium are excreted from the body within 3 days (99 percent). In mice, the median lethal dose of soluble palladium compounds (e.g., palladium chloride) is 200 mg/kg orally and 5 mg/kg intraveneously. Palladium is poorly absorbed and its toxicity is considered low, but it may be carcinogenic. Most plants tolerate it when it is present in low concentrations, although it is lethal to water hyacinth. Palladium serves no known biological role. Currency: Palladium, gold, silver, and platinum are the only metals that have ISO currency codes. The codes for palladium are XPD and 964. Cost: The price for palladium continues to rise. In 2016, palladium cost about $614 per ounce. In 2018, it reached $1100 per ounce.

Tips for Urban Stargazers

Tips for Urban Stargazers Stargazing in the city? Why not?  Just because someone lives in an urban environment doesnt mean they cant do a little sky observing. Sure, its a bit tougher because of bright lights and overall light pollution, but it can be done.   Most articles  about stargazing  recommend finding a good, dark-sky observing site. But for someone living in the city, who cant get to a dark-sky reservations, its tempting to just stay inside and look at the stars on a computer screen. However, it turns out, there are ways to do some city observing, despite the problems posed by light pollution. Much of the worlds population lives in or near cities, so enthusiastic city stargazers can and do find ways to do back-yard or rooftop observing.   Explore the Solar System The Sun, Moon, and planets are readily accessible because theyre bright. The Sun is an obvious choice, but observers do need to take some strict precautions. NEVER look directly at the Sun with the naked eye and especially NOT through binoculars or a scope that dont have solar filters. If an observer has a  telescope  equipped with a solar filter, then they can look at it through the eyepiece, to see the sunspots and any prominences that might be moving up from the Suns surface.  As it turns out, however, theres a very low-tech way to see sunspots without filters. Heres how it works: let the Sun shine through the telescope, and direct the bright light onto a white wall or a piece of paper. The observer gets to see sunspots without burning their eyes out. In fact,  a number of successful sunspot observers use this method all the time. That method also makes it very easy to sketch sunspots since all the observer has to do is direct the view onto paper and then trace what is projected. Checking out the Moon The Moon is also a great target for city viewing. Watch it night after night (and in the daytime during part of the month), and chart how its appearance changes. Its possible to explore its surface with binoculars, and get really finely-detailed views with a good telescope. One popular pastime is to explore all the large basins and craters on the surface.  Another one is to look for mountains and cracks on the surface.   One thing to look for during an observing session is an iridium flare. Thats a glint of light from the surface of an Iridium satellite. These usually happen not long after sunset and are very bright, so bright then can be seen from cities. However, as Iridium satellitesd are gradually phased out, such flares will happen less and less frequently. Seeing Planets from the City The planets are also good targets for city skygazers. The rings of Saturn and the moons of Jupiter  are popular targets. Plus, they show up well in binoculars or a telescope. There are good observing guides to the planets in the pages of Astronomy, Sky Telescope, SkyNews  magazines, as well as many sources online in other languages. A  digital astronomy program or app, such as StarMap 2 or Stellarium also provide precise positions of the Moon and planets in the sky.   The Deep Sky From the Big City Unfortunately, many people who live in light-polluted areas have never (or rarely) seen the Milky Way. During a power outage, theres a chance of seeing it from the city, but otherwise, it can be very difficult to spot unless they can get a few miles outside of town.   But, all is not lost. There are  some deep-sky objects that city dwellers can try to find. They just need to get out of the way of lights. One trick that many urban observers use is to stay up after midnight when some building owners turn off their outside lights. That might allow a view of such things as the Orion Nebula, the Pleiades star cluster, and some of the brighter star clusters. Other tricks for city observers: Find places to observe from that are shielded from bright nearby lights, such as a corner of a porch, the top of a roof and next to a wall, or from a balcony;Some put a blanket over their heads and their telescopes to block out the direct light;City astrophotographers take long-exposure images of deep sky objects;Use  good star chats  that help a skygazer hop from star to star as you search out a cluster or a nebula.   Ask the Locals Local planetarium theaters often offer stargazing shows, where people can learn the night sky.  They might also have classes for stargazers, so check out the nearby facilities to see what they offer. They are often found in science centers, but also at universities and some school districts offer public access from time to time. Amateur astronomer groups in and near big cities often have observing nights where people can gather with others to do some sky exploration. For example, in New York City, the Friends of the High Line organization have weekly observing sessions from April through October. Griffith Observatory in Los Angeles holds star parties each month, and its telescope is available each week for a peek at the heavens. These are just two of many, many stargazing activities in towns and cities. Also, dont forget the local college and university observatories- they often have observing nights, too. The city might seem like the least likely place to catch a glimpse of the stars, but in cities from downtown New York to Shanghai to Bombay and beyond, people can still often see the brightest stars and planets. It may be a challenge, but the rewards are worth it.

Effects of Cybercrime Essay Example | Topics and Well Written Essays - 1250 words

Effects of Cybercrime - Essay Example E-crimes are very sophisticated and target consumers, public and private institutions (Wall). Computer crimes range from outside parties hacking the computer networks and phish in malicious programs that give users a deceitful sense of security, instigating them to disclose vital information. Some of the effects of cybercrimes are: The greatest effect of cybercrime is the loss of intellectual property as well as confidential information of the business. However, it is not easy to determine the exactly the extent of the losses. Partially, cybercrime is not a zero-game because the stolen information is not fully gone. Infiltrators steal only the company plans including the customer lists and the working strategies (Westby). Amazingly, the company may not be aware that it is no longer in control of the information flow and they are controlled outside their infrastructure. The spies take control of the company’s network and access the information that runs the institution. More often, such infiltrators are the company’s competitors who wish to make similar products and compete equally. Even though they cannot produce exactly the same product, the idea is leaked out. The spies having the intellectual information can compete in the market, and the victim company may be grounded in its operations. This is because the competitor may produce cheap products that attract many customers in the market (Brenner). Every business entity strives to be unique in its operation. This implies that every organization has to conceal its vital information to be peculiar and be attractive to the customers. Such vital information may be stored in the computers and network framework of the organization. Although it may take some time for stolen IP to appear in the competing product, there is no deferment in monetizing abducted vital business information. For

Internal & external analyses of Lion Nathan Essay

Internal & external analyses of Lion Nathan - Essay Example This paper attempts to analyze the sustainable competitive advantage of Lion Nathan using SWOT (Strengths, weakness, opportunities, and threats) analysis, in which potential improvements may be seen in the identified weaknesses and threats, without overlooking its good points posed as strengths. Lion Nathan can be acknowledged for its strengths in terms of identifying its core purpose in the business, alongside its vision of making itself Australia’s and New Zealand’s leading alcoholic beverage company. This is undertaken with a stronghold on the company’s identity in the wine industry while making known its values of integrity, passion, acing together, and being sociable. These values, particularly the last one, are usually not found in other beverage companies, making Lion Nathan surge up to its sustainability purposes. It may also be emphasized that beverage companies are not that easy to build positive values and carry them out to the wider public due to the very nature of the business, but Lion Nathan is able to identify values that may be appropriately attached to the product. This is suggestive of leading and living clear values alongside demonstrating constructive behaviors with an intent to better engage its stakeholders in the business, a stra tegic task that is proved both effective and workable. This is how the company provides sustainable competitive advantage. The company’s aim of acting with integrity and doing the right thing for the long-term health of its business and the communities in which it operates is indicative of a long-term perspective. These are the strengths of Lion Nathan in terms of sustainable competitive advantage. The company’s involvement is sustained investment in community partnerships, responsible marketing initiatives, education and research initiatives, and reducing its
