The Effects of Smoking Bans on Victims of Exposure to Second Hand Smoke Exposure to second hand smoke, which for the purposes of this report will be designated SHS, poses extremely detrimental health risks for any and all individuals who consider themselves non-smokers, especially young children and pregnant women. SHS is estimated to contribute to heart attacks in nonsmokers and causes nearly 53,800 deaths in the United States alone on an annual basis.1 According to the United States Surgeon Generalââ¬â¢s report from 2010, tobacco use remains the single largest preventable cause of death and disease in this country, causing approximately 443,000 adult deaths from smoking-related illnesses each year.2 Additionally, smoking has beenâ⬠¦show more contentâ⬠¦Lung cancer was the most common cancer mortality in men and the second most common in women.6 The study also noted smoking differences in each of the three major language/cultural regions of Switzerland, with the mortality rates higher in the French and Italian speaking regions of the c ountry, reflecting the habits and mortality rates of both France and Italy, where smoking is much more prevalent, and the German region (which is by far the largest) having significantly lower smoking mortality rates, due to Germanyââ¬â¢s increased anti-smoking campaigns and laws protecting citizens from SHS.7 Although not as stringent as the US laws forbidding smoking in almost all indoor spaces, Europeââ¬â¢s leading countries are now attempting to curb the use of tobacco products, many for the first time in their histories. All studies have pointed to the extreme dangers SHS provides for pregnant women and children, especially adolescents. In a report published by the Center for Global Tobacco Control, it was demonstrated that efforts to curtail indoor exposure to SHS was working. The results of the study showed that the proportion of US middle and high school students who were exposed to indoor SHS actually declined from 65.5% in 2000 to 40.5% in 2009, with significantS how MoreRelatedSex And Age Disparity Among Teenagers1101 Words à |à 5 Pagesand Age Disparity in Teenage Exposure to Secondhand Smoke Anthony Kiprono PH 5302 04/30/2016 Second hand smoke is defined as the combination of smoke emitted by the burning end of cigarette or any other tobacco products and smoke emitted by the smoker.

The Discrimination Of A Male Dominant Company - 1888 Words
Throughout these difficult times in America we have all been faced with things that are more than unfavorable. However, I am pleased to say that the people I have the pleasure to work around and work with don t fit into that category. Like most they have their complaints and have witness or been a part of things that they don t necessarily agree with like the current election, blatant racism in society, or the general unfairness so many of us are subject to. I hate to say it but it s hard to remain above the nonsense. Most of my coworkers are people of color and they enjoyed being American and living in America. In my research the answers were different between my two interviewees but they were very similar in some ways, this was probably because I interviewed a male and female however, I wanted to get two different views from the opposite sex. The company that we work for is a software company, made up of mostly men and maybe about 5% women. Working in a male dominant company can b e difficult for any woman. However, my first interviewee Anusha remains strong doesn t let anyone push her around which was one of the reasons I decided to interview her. What I first noticed about both interviewees were that they were both so pleased to be in America.

Essay about Reflection on Rime of the Ancient Mariner
Reflection on Rime of the Ancient Mariner Samuel Coleridges poem entitled Rime of the Ancient Mariner is written as a ballad, in the general form of the traditional ballad of medieval or early Elizabethan times. Coleridge uses the ballad stanza, a four-line stanza. He is able to achieve a richer, more sweeping sense of the supernatural through these expansions; he is able to move beyond the more domesticated kind of supernaturalism of the four-line stanza. He starts with the usual ballad stanza in the first of the poem, in order to make the reader acquainted with the verse form and with the poetic ethos of The Rime of the Ancient Mariner (Beer 34). These early stanzas seem to anchor the readers mind. But in theâ⬠¦show more contentâ⬠¦He is condemned to wandering from place to place, where he must tell of his sin until the Second Coming of Christ. Coleridge used the story again in The Wanderings of Cain. Maud Bodkin writes that another great poet, William Wordsworth once said that the Mariner has no character (22-3) . But Charles Lamb, another contemporary of Coleridge, said the ancient Mariner as a character with feelings, faced with such happenings as the poem tells about, dragged [him] along like Tom Pipers magic whistle (House 107). John Livingston Lowes in more recent times spoke of the real protagonists in the poem as the elements, Earth, Air, Fire, and Water (Bodkin 20). Irving Babbit echoed Wordsworths criticism in saying that the Mariner does not do anything in the poem beyond shooting the Albatross, that the Mariner does not really act, but is acted upon only, and that the Mariner is an incarnation of the Romantic concern with the solitary (House 104-5). And a critic named George Herbert Clarke has interpreted the ancient Mariner to be at one and the same time himself as a real character in the poem, Samuel Taylor Coleridge, and all men; the Mariner is Representative Man, sinning, being punished, being redeemed (Beer 31). I imagine that one possibility, perhaps the best one, is to c onsider the Mariner as a poet more than a character in the sense in which we associate personality with characters in literature.

Strategic Management Strategic Scanning and Learning
Question: Discuss about the case study Strategic Management for Strategic Scanning and Learning. Answer: Synopsis The article discusses the steps necessary for the strategic management of an organization. The role of strategy is described as the different roles in the organization carried out by the different elements that are part of the organization. To implement the strategic management in an organization there are some preliminary tasks have to be completed first which is mostly about gathering knowledge about the environment the organization operates in along with the condition of the organization itself. The environment analysis is portrayed as the necessary way of gathering said information which help in the strategic decision making process. The environment analysis is divided into two parts external environment analysis that concerns the market conditions and internal analysis that is based on the processes internal to the organization (Drejer, 2004). The external environment analysis is done with the help of tools like PESTLE analysis that analyses macro environmental factors, SWOT analysis that analyses the micro environmental factors and porters five forces analysis that investigates the industry and the competition. Although useful to the extreme, the external environment analysis can not detract from the importance of internal analysis that is necessary to get the full picture as the internal analysis provide information about the operation and performance efficiency of the organization. A change in an organization is dependent on the independence of new strategy from previous ones so the nature of change depends on the impact of the new strategy (Judge, 2011). Knowledge management is necessary for the plan to succeed as the decision making process depends upon the readily available information (Tobin, 1998). Critique The article is right about the importance of internal and external analysis on the strategic management and the maintenance of the knowledge management standards. However, the limitation of one type of analysis from the other and the different types of information about the market and the organization that can be found from the different sources is unclear. It is indistinct about the individual importance of the different types of analysis and their contribution to the overall strategic planning of the future steps of the management. The knowledge management standards of the country and the different ways the strategic planning can be affected by the analysis is given but again no single tool or process has not been separated in the article (Jashapara, 2011). The role of knowledge management is given in the article as examples but their complete scope is not demonstrated with examples. Reflection It is easy to understand that the author of the article was focusing on the basic information about a process that can be quite complex in case of a specific organization so the information that is provided are the bare minimum. The framework for strategic planning is provided which can help in the understanding of the full process of strategic management. However, the information provided is too basic and brief for practical implementation without any other supporting document. To reflect on the purpose of the article and its scope, it can be said that the basic guideline of strategic management has been provided for better understanding of the process.

Physio Ex free essay sample
The maximum threshold will not change in cardiac muscle cells (as with any other cells), which is determined by the X amount of voltage needed for calcium channels to open. After this point, no additional voltage can cause the channels to open more, or again, prior to depolarization. 3. Why is it only possible to induce an extrasystole during relaxation. a. 3. cardiac is able to depolarize only after repolarization 4. explain why wave summation and tetanus are not possible in the cardiac muscle tissue. a. Cardiac cells have long action potentials and long twitches, therefore do not show temporal summation. Act 2 1. Explain the effect that extreme vagus nerve stimulation had on the heart. a. The vagus nerve stimulation caused the heart to flat line restart and react normally. The response after the stimulation that resumed the heart is called the vagal escape. 2. The SA node of the heart is located in the right arterial wall 3. We will write a custom essay sample on Physio Ex or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Describe how the sympathetic and parasympathetic nervous systems work together to regulate the heart rate. a. The sympathetic and parasympathetic are two branches of the autonomic nervous system. Both supply nerve impulses to the heart. The sympathetic (fight or flight), becomes more active when needed. Stimulation will increase the heart rate and force of contractions. The parasympathetic (resting and digesting) this branch is more active. Stimulation decreases the heart rate without directly changing force of contraction 4. What do you think would happen to the heart rate if the vagus nerve were surgically cut? a. The heart rate would increase but the heart would be damaged. The vagus nerve carries important information to the heart from the parasympathetic nervous system. This information is the decrease of heart rate, contraction strength, and the rate of the electrical impulses conducted in the heart. The sympathetic does the opposite and raise heart rate, contraction force and electrical conduction. Both of these systems work together. Act 3 1. Explain the effect that decreasing the temperature had on the frog heart. How do you think the human heart would respond? a. The colder temperature the heart rate is slower. A frog has no internal homeostatic regulating mechanism. The temperature will change depending on external environment. Because the human has an internal temperature of 35. 8-38. 2 degrees C even when the external environment changes. A cooler temperature for a humans heart rate would decrease and possibly be hypothermic in extreme external temperature conditions. 2. Describe why Ringers solution is required to maintain heart contractions? There are electrolytes of calcium, chloride, sodium, potassium, and magnesium. This is meant to keep the isolated intact heart workable. 3. Explain the effect that increasing the temperature had on the frog heart rate. How do you think the human heart would respond? The hotter he temperature for the frog the heart rate would increase. The human heart rate would increase and maybe not be able to maintain its homeostasis and possibly become hyperthermic, in extreme external temperature conditions. A frogs internal body temperature changes depending on external environment and has no internal homeostatic mechanisms to regulate temperature. Act 4 1. Atropine is an â⬠Å"acetylcholine antagonist. â⬠Does atropine inhibit or enhance the effects of acetylcholine? a. Describe your results and how they correlate with how the drug works. Yes. The heart rate increased from 44 to 69. The modifier worked in the opposite to the neurotransmitter, so this would be an antagonist. 2. Describe the benefits of administering digitalis? a. Digitals are used to bolster a weak heart in congestive heart failure. People with a bad heart need to have maximum time for the venous return and increased stroke volume would benefit from increased force of contraction and decreased heart rate. 3. Distinguish between cholinergic and adrenergic chemical modifiers. Include examples of each in your discussion. a. Cholingeric and adrenergic modifiers inhibit, mimic, or enhance the action of acetylcholine in the body. Pilocarpine is a direct acting cholinergic agonist that decreases the heart rate by directly acting on the receptor the same as acetylcholine. Atropine is a cholingeric antagonist that blocks the acetylcholine receptor increasing the heart rate. Epinephrine is an adrenergic agonist and binds to adrenergic receptor like B1, B2, and Alpha1 and increases heart rate. This mimics effect of the sympathetic nervous system. Act 5 1. Describe the effect that increasing the potassium had on the heart in this activity. How did this change the resting membrane potential of the cardiac muscle cell? a. Excessive potassium decreases the resting otential of the plasma membrane and decreases the force of contraction. The ectopic pacemakers can be caused by leakage of potassium into cardiac cells. The pacemakers then show in abnormal locations of the heart muscle. This decreases the force of contraction with a negative inotropic. In the experiment the heart was decreased to 28 and then erratic. 2. Des cribe how medicines called ââ¬Å"calcium channel blockersâ⬠are used to treat patients and why? a. They are used to treat high blood pressure and abnormal heart rates. This blocks movement of calcium through channels and throughout phases of cardiac action potentials.

Wastewater Treatment Essays - Sewerage, Environmental Engineering
Wastewater Treatment The reason for me doing this report is because I could not attend class enough to grasp the concept of Wastewater Treatment. This report is an overview of each stage of the treatment of sewage. I have included a diagram of a typical sewage plant. A) Primary Treatment The wastewater that enters a treatment plant contains debris that might clog or damage the pumps and machinery. The material is removed by screens, and is burned or buried. The wastewater then passes through a comminutor (grinder), where all the organic material such as leaves are mushed smaller so that they can be removed later. 1) Grit Chamber Back in the day, long narrow channel-shaped settling tanks, known as grit chambers, were used to remove all the inorganic substances like sand, silt, gravel, and cinders. These chambers were made to allow inorganic particles 0.008 in. or bigger to settle at the bottom while the smaller particles and most of the organic material that remain in suspension pass through. Today, spiral-flow aerated grit chambers with hopper bottoms, or clarifiers with automatic scrapper arms are used. The grit is removed and disposed of as sanitary landfill. Grit build up can reach from 3 to 8 cubic feet per1 million gallons of wastewater. 2) Sedimentation With the grit removed, the wastewater goes into a sedimentation tank, where the organic materials removed. The method of sedimentation can remove about 20 to 40 percent of the biochemical oxygen demand and 40 to 60 percent of the suspended solids. The big boys in the industry use a chemical process known as coagulation and flocculation in the sedimentation tank. I really don't know much about this subject so I'm going to move on. 3) Flotation The alternative to sedimentation is a treatment called flotation, in which air is forced into the wastewater under pressures of 25 to 50 lbs per sq. in. The wastewater, is compressed with air, is then released into an open tank ; there the rising air bubbles cause the suspended solids to rise to the surface, where the are wisked away. Flotation can remove more than 75 percent of the suspended solids. 4) Digestion Digestion is a microbiological process that changes the chemically complex sludge to methane, carbon dioxide, and a harmless fertilizer. The reactions occur in a closed tank or digestor that is oxygen deficient. The transformation happens after a series of reactions. First the solid matter is made soluble by enzymes, then the substance is fermented by a group of acid-producing bacteria, reducing it to simple organic acids such as acetic acid. The organic acids are then resolved to methane and carbon dioxide by bacteria. The sludge that is to thick is heated and added to the digester as many times as possible, where it sits for 10 to 30 days and is decomposed. Digestion reduces organic matter by 45 to 60 percent. 5) Drying The digested sludge is place on sand beds for air drying. Air drying needs dry, warm weather for it to work. Some plants have shelters over the sand beds. Dried sludge in most cases is used as a fertilizer because of the 2 percent nitrogen and 1 percent phosphorus content. B) Secondary Treatment After removing 40 to 60 percent of the suspended solids and 20 to 40 percent of the BOD5 in the primary stage by physical resources, the secondary treatment biologically reduces the organic material that stayed in the liquid stream. Secondary treatment contains keeping and speeding up nature's process of waste disposal. Aerobic bacteria in the oxygen change the organic matter to stable forms such as CO2 , water, nitrates, and phosphates. The new organic material that is made is an indirect result of biological treatment processes, and is removed before the wastewater is dumped into the streams. 1) Trickling Filter In this process, a waste stream is sent over a bed or column of some type of porous medium. A sticky film of microorganisms coats the medium and acts as the removal agent. The organic matter in the waste stream is absorbed by the film and changed to carbon dioxide and water. If the trickling filter step comes before the sedimentation stage it can remove about 85 percent of the BOD entering the plant. 2) Activated Sludge This stage is an aerobic process that adds sticky sludge particles that have millions of of actively growing bacteria stuck together by a gelatinous slime. Organic matter is assimilated by the floc and changed to aerobic output. The reduction of BOD varies between 60 to
