Acid Rain Essays - Inorganic Solvents, Mineral Acids, Smog, Oxides

Acid Rain Acid rain is a serious problem with disastrous effects. Each day this serious problem increases, many people believe that this issue is too small to deal with right now this issue should be met head on and solved before it is too late. In the following paragraphs I will be discussing the impact has on the wildlife and how our atmosphere is being destroyed by acid rain. CAUSES Acid rain is a cancer eating into the face of Eastern Canada and the North Eastern United States. In Canada, the main sulphuric acid sources are non?ferrous smelters and power generation. On both sides of the border, cars and trucks are the main sources for nitric acid(about 40% of the total), while power generating plants and industrial commercial and residential fuel combustion together contribute most of the rest. In the air, the sulphur dioxide and nitrogen oxides can be transformed into sulphuric acid and nitric acid, and air current can send them thousands of kilometres from the source.When the acids fall to the earth in any form it will have large impact on the growth or the preservation of certain wildlife. NO DEFENCE Areas in Ontario mainly southern regions that are near the Great Lakes, such substances as limestone or other known antacids can neutralize acids entering the body of water thereby protecting it. However, large areas of Ontario that are near the Pre?Cambrian Shield, with quartzite or granite based geology and little top soil, there is not enough buffering capacity to neutralize even small amounts of acid falling on the soil and the lakes. Therefore over time, the basic environment shifts from an alkaline to a acidic one. This is why many lakes in the Muskoka, Haliburton, Algonquin, Parry Sound and Manitoulin districts could lose their fisheries if sulphur emissions are not reduced substantially. ACID The average mean of pH rainfall in Ontario's Muskoka?Haliburton lake country ranges between 3.95 and 4.38 about 40 times more acidic than normal rainfall, while storms in Pennsilvania have rainfall pH at 2.8 it almost has the same rating for vinegar. Already 140 Ontario lakes are completely dead or dying. An additional 48 000 are sensitive and vulnerable to acid rain due to the surrounding concentrated acidic soils.? ACID RAIN CONSISTS OF....? Canada does not have as many people, power plants or automobiles as the United States, and yet acid rain there has become so severe that Canadian government officials called it the most pressing environmental issue facing the nation. But it is important to bear in mind that acid rain is only one segment, of the widespread pollution of the atmosphere facing the world. Each year the global atmosphere is on the receiving end of 20 billion tons of carbon dioxide, 130 million tons of suffer dioxide, 97 million tons of hydrocarbons, 53 million tons of nitrogen oxides, more than three million tons of arsenic, cadmium, lead, mercury, nickel, zinc and other toxic metals, and a host of synthetic organic compounds ranging from polychlorinated biphenyls(PCBs) to toxaphene and other pesticides, a number of which may be capable of causing cancer, birth defects, or genetic imbalances. COST OF ACID RAIN Interactions of pollutants can cause problems. In addition to contributing to acid rain, nitrogen oxides can react with hydrocarbons to produce ozone, a major air pollutant responsible in the United States for annual losses of $2 billion to 4.5 billion worth of wheat, corn, soyabeans, and peanuts. A wide range of interactions can occur many unknown with toxic metals. In Canada, Ontario alone has lost the fish in an estimated 4000 lakes and provincial authorities calculate that Ontario stands to lose the fish in 48 500 more lakes within the next twenty years if acid rain continues at the present rate.Ontario is not alone, on Nova Scotia's Eastern most shores, almost every river flowing to the Atlantic Ocean is poisoned with acid. Further threatening a $2 million a year fishing industry. ? Acid rain is killing more than lakes. It can scar the leaves of hardwood forest, wither ferns and lichens, accelerate the death of coniferous needles, sterilize seeds, and weaken the forests to a state that is vulnerable to disease infestation and decay. In the soil the acid neutralizes chemicals vital for growth, strips others from the soil and carries them to the lakes and literally retards the respiration of the soil.

Adverbs of Frequency Sentence Placement

Adverbs of Frequency Sentence Placement Adverbs of frequency tell us how often something happens/is the case, happened/was the case, will happen/will be the case, etc. There are lots of them. Here are some examples: always - Peter is always getting into trouble.usually - They usually get their work done on time.frequently - My sister frequently goes shopping in Seattle.rarely - They rarely ask questions about the homework. Most Common Adverbs of Frequency The most common adverbs of frequency in English in order from most often to least often: always - He always does his homework.usually - They usually complete the work on time.often - I often watch movies online.sometimes - Jack sometimes comes over for dinner.  occasionally - She occasionally asks a question.rarely - They rarely have any homework.never - I never complain at work.   Where Do They Appear in the Sentence? Word order can be confusing with adverbs of frequency. Here are different rules for placement in sentences. 1. In a Sentence With One Verb If the sentence has one verb in it (e.g. no auxiliary verb) we usually put the adverb in the middle of the sentence, i.e. after the subject and before the verb: subject / adverb / verb / predicate Tom usually goes to work by car.Mary often asks me for help.   2.  Usually After the Verb Be The adverb usually comes after the verb be: subject / verb / adverb / predicate Tom is often late.Anne isnt usually sick.Peter isnt always right. This is not the case if we put the adverb at the beginning or end of the sentence for emphasis. This rule also does not apply to short answers: Is she usually on time?Tell her not to be late.Yes, she usually is.She never is. The rule is broken in other cases too, e.g. Conversation 1 Speaker A: What are you doing here? Shouldnt you be at school?Speaker B: I normally am at school at this time, but my teacher is ill.   Conversation 2 Speaker A: Youre late again!Speaker B: usually am late on Mondays because the traffic is so bad. Conversation 3 Speaker A: Tom is late again!Speaker B: Tom usually is late.   3. In a Sentence With More Than One Verb If the sentence has more than one verb in it (e.g. auxiliary verb) we usually put the adverb after the first part of the verb: subject / helping verb or modal / adverb / main verb / predicate I can never remember his name.Anne doesnt usually smoke.The children have often complained about the playground facilities. Exception: In sentences with have to the adverb is in position A: subject / adverb / have to / main verb / predicate We often have to wait for the bus.She never has to do any housework.They sometimes have to stay after class.   4. When Using for Emphasis For emphasis, we can put the adverb at the beginning or end of the sentence. At the end is unusual - we usually only put it there when we have forgotten to put it in earlier. adverb / subject / main verb / predicate Sometimes we go to school by bus.Often he waits for her after class.Usually, Peter arrives early for work. or subject / main verb / predicate / adverb We go to school by bus sometimes.They like to watch TV often.Jennifer buys a new car rarely. Exceptions: Always cant go at the beginning or end of the sentence. Never, seldom, rarely cant go at the end of a sentence. They only go at the beginning of a sentence in polemic statements. Then they have to be followed by the word order for questions: Never has there been a better time to overcome our differences.Rarely do we have an opportunity like this.Seldom had the orchestra given a worse performance.   5. In Question Form When using adverbs of frequency in the question form, put the adverb before the main verb. auxiliary verb / subject / adverb / main verb / predicate Do you often go to the cinema?Did he sometimes leave the classroom?Do they usually come late to class? Exceptions: Never, seldom, rarely and other adverbs of frequency with a negative sense are not usually used in the question form. 6. In the Negative Form When using adverbs of frequency in the negative form, put the adverb before the main verb. subject / helping verb / adverb / main verb / predicate They dont often go to the cinema.She doesnt usually wait for an answer.Peter doesnt normally want to come with us.   Exceptions: Never, seldom, rarely and other adverbs of frequency with a negative sense are not usually used in the negative form.

Use of simulated learning in Radiology. Current state of affair Article

Use of simulated learning in Radiology. Current state of affair - Article Example Simulator models are effective in environments that are risk-free in training skills. The models also help to improve the safety of the patients in radiology training. The Board of surgery in America has made it mandatory for surgeon trainees to undergo a simulation test before taking the summative examination. It will become an essential tool for medical practitioners just as it is for pilots (Levine, 2013: Collins, & Stern, 2008). Researchers are looking for ways of integrating technology and knowledge from areas like surgery and anesthesia to the field of radiology. Paige argues that many programmes of teaching prefer having residents to learn with simulators for time maximization with patients. Simulation aids residents in developing confidence when it comes to dealing with infrequent events that are critical. Simulation can be well merged with interventional radiology (IR) given that IR is procedural (Pasler, 1992: Patel & Joseph, 2012: Bessemer & Myers, 1998). After internalizing basic skills like tying knots, residents can advance to use of virtual reality machines which stimulate procedures like selective arterial catheterization. Embolism is one of the events that can arise and it can be dealt with through simulation. Training by simulation has performed a major role in reliability and performance improvement in radiology and medical organizations by reduction of human factors. Simulation focuses on decision making, training of clinical teams, safety of patients and management of errors. The training of teams is viewed in a multi-disciplinary way. It should be able to respond to the changing radiology environment. Advancements in teamwork have resulted to high job satisfaction, high efficiency, increased productivity and safer ways of patient care. Simulation, when integrated in radiology programmes helps to train and acts as a remedy to limited

Bait Al Zubair houses one of Oman's finest and most comprehensive collections of antiques from all over the Sultanate. Anyone interested in learning more about Omani culture will definitely want to add this museum to his or her itinerary. Its displays include traditional Omani weaponry, jewellery, costumes, domestic utensils and recreated urban and rural environments. There is a coffee shop and souvenir shop selling a unique range of items most of which are based on the museum collection. A library that can be used for reference only by appointment, it offers a chance for scholars and researchers to extend their knowledge of Oman. Friendly Omani guides are on hand to explain the exhibits and add a real sense of discovery to Oman's culture and traditions. When I arrived at Baiz Al Zubair Museum for the first time for placement, I was supplied a document containing an introduction to Bait Al Zubair, current roles Performed by Bait Al Zubair, my Job description, experience required, staff organization chart and general guidelines to working at Bait Al Zubair. Bait Al Zubair Museum is an exhibition of a private collection that uses the wealth of Oman's historical past to explain the collection rather than vice versa. It can be considered as the Al Zubair family's private tribute to Oman. Bait Al Zubair Museum is located in Al Saidiya Street in old Muscat. One goes through Muscat Gate and it's just after the bend on the right-hand side of the road (opposite Bait Muzna Gallery) and just before the HSBC Bank. This privately-run Museum also has a traditional Omani "town house" (tours 1730 hours daily) and a small gift/book shop.

Muscat is the capital of Oman since 1784 and has a great deal of charm and character and offers the combination of the relaxed atmosphere of an Indian Ocean town set amongst the well ordered life of a modern oil state. The original town of Muscat forms but a fraction of the

The History Of Shamanism Theology Religion Essay

The History Of Shamanism Theology Religion Essay Shamanism is a huge factor in most traditional religions, some of which include the Africans, Native Americans, many parts of Asia, as well as other cultures. Although the definition of a shaman differs from one region to the next, the general dictionary definition of a shaman is A member of certain tribal societies who acts as a medium between the visible world and an invisible spirit world and who practices magic or sorcery for purposes of healing, divination, and control over natural events. The term shaman originated in the Mongol and Turkish area and is translated literally as one who knows which connects to their knowledge of the ways to manipulate spirits and magic. With Shamanism being involved in so many different cultures, its difficult to give it just one definition, so in this paper I will go through a few of the cultures and explain their specific definition of shamanism and the different aspects involved in African traditional religions. African Shamanism There are many different aspects to African shamanism. The main definition of shamanism in Africa has a good connotation and usually involves manipulation of spirits or earthly substances to heal, direct, or do beneficial work for others. Some of the specific names of these shamans are rainmakers or heaven herders, herbalists or medicine men, and diviners. Not all people use their sources for good works, and when a shaman begins using his or her techniques for evil doings, they then acquire the name of witch or sorcerer. Such is the case in most other cultures as well. There are two distinctive traditional religions in Africa-Zulu and Yoruba. They have many similarities as well as differences. The Zulu stick mostly to the hills because of their geographical location, and in turn consider hills to have spiritual significance. Because hills have such special meaning, the Zulu build their towns, or kraals, on the hillsides in a circular formation with the gates facing east (do to significance of the sun), the herd in the center of the kraal, and the headman, known as the umnumzane, is on the west side of the kraal. The umnumzane has a lot of influence on the tribe. He holds the political, social and religious leader roles over the whole tribe, and is often a diviner. The headman of each Zulu kraal is the chief official of the village and also that person most directly responsible for the performance of the ritual acts expected of all Zulu, especially those that address the ancestors.  [1]  Besides solving disputes or making decisions within his kraal, one of the umnumzanes main roles is contact with the ancestors. He will perform all the rituals and such things to please the ancestors for everyone within his kraal. The ancestors play a huge part in Zulu beliefs and so the role of the umnumzane is very important. The people want to keep the ancestors happy so that they will continue to have good fortune in their lives. According to most African traditional religions, the ancestors do not cause misfortune, but other people do. The authority system is quite similar in the Yoruba tribes. Their political, social and religious leader is one and the same, but rather than having a settlement on a hillside where the rituals involve all of the community under one leader, the religious obligations are put on the head of the family, or the olori ebi, and that person does the communication with the ancestors, and keeps them happy and such. Each family has its own shrine. The community still gets together as a whole to perform religious ceremonies, but it is more focused on the family. Divination is used to determine solutions to problems, to depict reasons of misfortune, or even to predict the future. In the Zulu culture, diviners must be called by means of a dream or vision that is followed by aches, pains, or other bodily dysfunctions. Anyone can become a diviner, although typically women occupy the position. Once called, the person will need to be trained by an experienced diviner. The Yoruba are a bit different with their diviner. They have a priestly cast, and one part of the caste called the Orunmila specifically use divination practices to contact one particular god for answers. Like the Zulu though, the one that will become a diviner will go through extensive training from an experienced diviner. Diviners in both circumstances have many means of doing their work. They can use elements such as water, fire, bones, sticks, etc. to find their answers, and with these objects, they have created means of interpreting the signs from each. In some circumstances, the diviners will allow themselves to be in a trance that allows them to communicate with the spirits, or even be possessed by the spirits in order to find the answers for their clients, but typically the diviners are the ones manipulating the spirits and getting their knowledge rather than being used by the spirits. Once people have determined what their problem is from the diviner, they then go to a herbalist for a remedy. Herbalists could easily be translated to doctors and serve the same role in both the Zulu and Yoruba. They were trained to know well which herbs or remedies worked for the different circumstances. Part of the traditional religions is that spirits live in many of the nature elements, and so herbalists used this theology in their works as well. They would use certain plants or locations because of the spiritual elements involved, and would manipulate the spirits in such a way to cure their client. Whereas most diviners are women, most herbalists are men. Knowledge of medicine is usually handed down from father to son.  [2]  Along with the passed on knowledge, herbalists were always open to new information. This includes realistic information, as well as spiritual insights. Another form of spirit manipulation in the Zulu is the izinyanga ezulu, or heaven herders. Heaven herders are always men, and have to be called in some way by the Sky God. Their job is to control where storms and such go. They are said to be disciples of the Sky God, as well as a medium between the people and the Sky God. With cattle and agriculture being a huge part of the Zulu culture, it makes sense that the sky is handled as cattle are, and that the weather needs to be controlled for the sake of those who own raise crops to feed the people. The Yoruba hold no such position, although they do also worship a similar god with their priestly cast. They (diviners) are not the only supernaturally inspired helpers people turn to for advice. Many consuld mediums who communicate with spirits while in a trance. Some may be possessed only once or twice in their lifetime, but others claim to be in regular contact with one or more familiars that they can identify by name.  [3]  The Yoruba called these people elegun. Among the Zulu, only the diviner could do such, but the with the Yoruba, anyone could be used as a medium; they did not need to be a diviner. The Yoruba also have people that are called the egungun. The egungun are masked dancers that perform for the ancestors. They have special masks that are connected spiritually to the ancestors and are said to have great power. Only men are allowed to be egungun, with the exception of one woman, who is the director or dresser. One has to earn the title of egungun by going through a certain process. While most of those positions are very open to the public and or the good of the community, some people misuse their abilities. Such people are called witches or sorcerers. Since the peoples believe that the spirits do not cause any harm, all bad things are supposedly a result from witches and sorcerers. According to the Zulu, someone could be a witch without realizing it. Their very presence would bring misfortune to those around them. In most cases though, in both the Zulu and the Yoruba, the witches are shaman that use their talents for evil. They twist the system from using their powers mischievously. They work secretively, and usually only at nights. Although trying to differentiate between witches and sorcerers is difficult, there are a few small means of differing them. Sorcerers tend to work alone where as witches will gather together at night and work as a team. Another supposed trait of sorcerers is the ability to shape-shift. There one story of sorcerer luring a woman to fall in love with him. He offered to marry her, and on their trip back to his village the stopped for the night. During the night he transformed into a lion in order to eat her. Luckily for her, her brother did not trust the man and followed them, and proceeded to protect his sister from being eaten. Other stories tell of sorcerers taking on the form of an owl for means of escaping their house silently and unknowingly. Another supposed trait of sorcerers is their ability to use the undead. They can kill a person using their black magic, and then use the persons dead body for their own use. Witches are most often depicted as using voodoo, charms and curses. Voodoo involves acquiring a part of someone, such as a hair, nail, or something of the sort, and it is added to a certain object that the witch makes. The part of the person connects them to the witches object, and the witch is able to toy with the person in this way. Charms could be an object that has been chanted over and charged with magic. A charm could be a piece of paper with a chant written on it that could be worn, or a charm could simply be a chant itself used in moments of needed protection or other. Most often, people would get charms to protect themselves from witches curses. The last main thing that witches use is curses. Curses, hexes, spells, or whatever you may call them, have been a worry of average people for longer than history can tell. Often it is a chant said with emotion over a person to bring misfortune on them. They can be spoken in an unknown language, which is said to have more impact on th e target. Native American Shamanism Native American shamanism is similar in a lot of ways, as well as different in a lot of ways. Shamans are viewed in a good way, where their work is for the better of the community. Each nation had spiritual leaders and healers each one had different beliefs of what practices were done. The Lakota believed that their spiritual leaders were in constant communication with Wakan Tanka or The Great Spirit. Their role was to seek spiritual enlightenment and secure the tribes good graces with the spirit world. They were healers of the mind and body.  [4]  They have healers-which is the same idea as herbalists-diviners, and mediators, as well as witchcraft. Native Americans have strong ties with animals though. To the Native Americans, the medicine men are not so much magical in their works, but they are knowledgeable people who have a greater understanding and like to think. Their natural abilities make them suitable to be medicine men. Medicine men more frequently appeared in tribes that were able to be open and exchange thoughts and knowledge with other tribes. Most often fathers would pass down knowledge to their sons and so the title stayed within the family that way. The Native American divination practices differed from that of the Africans. They often used stars, and things of nature to determine the answers that were sought. Sometimes they would use a pipe, and the answers would come through their opened mind from the smoke. They still used divination in the same way as the Africans, so use the spirits to find answers for their clients. Witchcraft, although not the technical title, in the Native American tribes had a much different feel though. Rather than voodoo and curses, the Native American bad shamans worked with charms and animals. The charms again were certain made objects that had been charged with power, and were used to protect the person from evil and misfortune. The Native Americans had an interesting relationship with animals. A power animal protects you physically and provides you with emotional support, wisdom, and vital energy. Some people think a power animal is a spirit being that stays with you because it cares for you and enjoys being able to experience life in a physical body. Others think a power animal is a symbol for ones subconscious wisdom. Almost everybody has a power animal; some have several. (Perhaps you had an invisible animal friend as a child or have always been fascinated with a particular kind of animal. This animal may be your power animal.) A person may in the course of life lose contact with the power animal, thereby losing the animals protection, wisdom, and energy. If you lose contact with your power animal, you may feel dispirited, you may become sick easily, or you may be accident-prone. The shamanic healing technique of power animal retrieval can restore a persons connection to a power animal. A person can also journey to find his or her own power animal.  [5]  With this emphasis on animals, often the bad shamans could be connected shape-shifters that caused issues. The main evil in Native American beliefs was evil spirits. With a belief in the ancestor spirits and animism, the Native Americans had to always keep all the spirits happy, and misfortune was often cause by spirits, thus the need for protective charms and shared power of animal spirits. Conclusion Despite having minimal contact between these 2 cultures, it is surprising that they share such similar roles. On the other hand, this shows the nature of humans over all with paranoia of spirits and bad luck, as well as the respect for ancestors. Shamanism is a big part of both cultures, and has many different aspects to it.

Long-Term Structural Change Essay -- Organizational Change, Change Pro

A lot of organizations initiate change programs and action plans that vanish after a while but have had, it’s hoped, some impact on performance, even though one cannot be sure. The first challenge when initiating change is to make sure that every employee understands that this business system is not an action plan; it’s a faith that is about what should characterize a really good company, and there are no option to this faith. It is important to put a lot of effort into making everybody understand this (Ahlberg & Nauclà ©r, 2007). Long-term structural change has four characteristics: scale which is the change that affects all or most of the organization, magnitude which entails significant alterations of the status quo, duration or the length of time it lasts, and strategic importance. Yet companies will garner the rewards only when change takes place at the level of the individual worker. There is no single methodology fits every company, but there is a set of practices, tools, and techniques that can be tailored to a variety of situations. Using a systematic, comprehensive framework, allows executives to understand what to expect, how to manage their own personal change, and how to engage the entire organization in the process (Jones, Aguirre & Calderone, 2004). An official approach for managing change that starts with the leadership team and then engages key stakeholders and leaders should be developed near the beginning, and modified frequently as change moves through the organization. Since change is intrinsically unsettling for people at all levels, when it is on the horizon, all eyes will turn to the CEO and the leadership team for strength, support, and direction. The leaders themselves must accept the new approach... ... of the outlook they seek to create, and the principles and guiding practise by which they hope to get there. The fourth discipline is team learning. Through methods like dialogue and skilful discussion, teams alter their collective thinking, learning to mobilize their energies and ability beyond the sum of individual members’ talents. The fifth discipline is systems thinking. In this discipline, people learn to better understand interdependency and change, and thus to deal more effectively with the forces that shape the consequences of actions (Green, 2007). This means that change must be driven by developing competence within the organization, by managers and workers in each unit creating and taking ownership of their change programs because they are motivated by pride in improving their professionalism and achieving better results (Ahlberg & Nauclà ©r, 2007).
