Respiratory Diseases free essay sample

Respiratory disease is a medical term that encompasses pathological conditions affecting the organs and tissues that make gas exchange possible in higher organisms, and includes conditions of the upper respiratory tract, trachea, bronchi, bronchioles, alveoli, pleura and pleural cavity, and the nerves and muscles of breathing. Respiratory diseases range from mild and self-limiting, such as the common cold, to life-threatening entities like bacterial pneumonia, pulmonary embolism, and lung cancer.The study of respiratory disease is known as pulmonology. A doctor who specializes in respiratory disease is known as a pulmonologist, a chest medicine specialist, a respiratory medicine specialist, a respirologist or a thoracic medicine specialist. Respiratory diseases can be classified in many different ways, including by the organ or tissue involved, by the type and pattern of associated signs and symptoms, or by the cause (etiology) of the disease. Inflammatory lung disease Characterised by a high neutrophil count, e. . asthma, cystic fibrosis, emphysema, chronic obstructive pulmonary disorder or acute respiratory distress syndrome.

Obstructive lung diseases Obstructive lung diseases are diseases of the lung where the airways (i. e. bronchi, bronchioles, alveoli) become reduced in volume or have free flow of gas impeded, making it more difficult to move air in and out of the lung.Chronic Obstructive Pulmonary Disease (COPD), which includes asthma an example of an obstructive lung disease, is where the airways become damaged, causing them to narrow. Restrictive lung diseases Restrictive lung diseases (also known as interstitial lung diseases) are a category of respiratory disease characterized by a loss of lung compliance,[2] causing incomplete lung expansion and increased lung stiffness. E. g. in infant respiratory distress syndrome (IRDS). Respiratory tract infections Infections can affect any part of the respiratory system.They are traditionally divided into upper respiratory tract infections and lower respiratory tract infections. Upper respiratory tract infection common cold however, sinusitis, tonsillitis,pharyngitis and laryngitis are Lower respiratory tract infection pneumonia, tuberculosis Diagnosis Respiratory diseases may be investigated by performing one or more of the following tests Chest x-ray Pulmonary function test Computed tomography scan Culture of microorganisms from secretions such as sputum Bronchoscopy Biopsy of the lung or pleuraVentilation perfusion scan Ultrasound scanning Epidemiology Respiratory di sease is a common and important cause of illness and death around the world. In the US, approximately 1 billion common colds occur each year. [5] In the UK, approximately 1 in 7 individuals are affected by some form of chronic lung disease, most commonly chronic obstructive pulmonary disease, which includes asthma, chronic bronchitis, and emphysema. [6] Respiratory diseases (including lung cancer) are responsible for over 10% of hospitalizations and over 16% of deaths in Canada

The 4 Types Of ACT Reading Passages You Should Know

The 4 Types Of ACT Reading Passages You Should Know SAT / ACT Prep Online Guides and Tips One of the nice things about the ACT is that it doesn't change all that much from test to test. This is especially true for the Reading section: Reading is always the third section of the ACT, there will always be passages on four subject areas, and each subject area will have 10 questions. So what are the 4 types of ACT Reading passages? Read on to find out! feature image credit: Four by Jukka Zitting, used under CC BY 2.0/Cropped from original. 4 Passages To Rule Them All The 4 types of passages on the ACT are always the same, and always presented in same order: 1. Prose Fiction/Literary Narrative, 2. Social Science, 3. Humanities, and 4. Natural Science. ACT, Inc. has an exhaustive list of all the topics that might be covered in each of these areas, but it's kind of overwhelming. To make it a little easier to understand what exactly is covered in each subject area, I've summarized each passage type, along with the questions that you’re likely to see on them, below. Prose Fiction/Literary Narrative These passages usually consist of excerpts from fiction or literary memoirs. You're likely to be asked... questions about the main theme questions about the narrator's tone and intent (e.g. what did the narrator mean when she used this particular phrase or word?) which questions are and are not answered by the passage Social Science These passages usually consist of straightforward discussions of topics in the social sciences, including areas like psychology (study of the mind), sociology (study of societies), and education. You're likely to be asked... to paraphrase how information from the passage describes subject of the passage which statements the author would agree with (that is, what's the main point of the passage) If the passage is about a particular person (like Harriet Tubman), there will often be questions about the passage subject’s point of view, rather than author’s point of view (in contrast with Prose Fiction/Literary Narrative or Humanities passages, which often deal with the author or narrator's points of view). Humanities These passages from can be from personal essays or memoirs, as well as on humanities subject areas like the arts, literature, media, or philosophy. Questions on Humanities passages are similar to Prose Fiction in that you're more likely to be asked about the tone or point of view of the passage or the narrator as compared to the Social Science or Natural Science passages. Natural Science These passages are nonfiction writing about SCIENCE. The topics can range from subjects that you've probably covered in school, like bio, chemistry, or physics, to more esoteric areas like astronomy, technology, or medicine (no paleontology yet, but I can always dream). You do not need a science background to understand the passages; all you need are solid reading comprehension skills. (The same is true of the ACT Science section). Becoming familiar with science writing, however, might make you feel less intimidated by these passages when you have to deal with them on the ACT. Similar to Social Science questions, Natural Science questions tend to be more focused on specific detail or statements that can be backed up with evidence from passage. A typical question you might see is "Which of the following statements is supported by the information in the fourth paragraph?" How Do I Know Where My Problems Are? So how do you know if you struggle with some passage types more than others? Follow these steps to find out your weaknesses. Step 1: Take a timed practice ACT test, in order, and score it. Because Reading appears third on the ACT, it's important to take it as part of an entire timed and in-order ACT. How your brain copes with the Reading section when you're just practicing reading passages and answering questions on them is very likely different than how it will do after it's been tired out by English and Math. Step 2: Compare your Social Studies/Sciences and Arts/Literature subscores. Your Social Studies/Sciences subscore is simply the combination of your scores on questions on Social Science and Natural Science passages, while your Arts/Literature subscore is the combination of your scores on questions on Prose Fiction/Literary Narrative/Humanities passages. Most official scoring charts will provide you with the information you'll need to calculate these subscores, which will be out of 20. You can even calculate them for yourself: your Arts/Litereature subscore = questions 1-10 + questions 21-30, while Social Studies/Sciences subscore = questions 11-20 + questions 31-40. Is there a significant difference between your Social Studies/Sciences and Arts/Literature subscores? More than a 1-2 point difference between subscores indicates a difference worth checking into. For instance, if you got a 12/20 Social Studies/Sciences subscore and a 17/20 Arts/Literature subscore, you definitely would want to focus your studying on Social Science and Natural Science passages. Step 3: For each of the four passage types, compare how many questions you answered incorrectly. Since there are 10 questions in each section, it's pretty easy to do percentages - 1 question wrong is 90%, 4 questions wrong is 60%, and so on. Comparing your scores on each of the passage types can be really illuminating, because it can shed light on areas you may not have realized you had issues with. Remember, it’s not just important that you’re comfortable with reading the passages: it’s important that you can successfully extract info from them to answer questions correctly. Example from my life: Prose Fiction passages are the least straightforward to read for me, but I find the questions on these types of passages the easiest because there are fewer concrete things to ask about (especially when compared to Social Science or Natural Science passages). When I did a timed practice Reading ACT, I got 1 wrong on Social Science and 2 wrong on Natural Sciences passages; if I were taking the test for real, I would start my studying by first focusing on Natural Science passages and then Social Science passages. Step 4: To be absolutely certain, take multiple timed ACT practice tests Sometimes, even if you normally do well on a passage type, a particularly difficult passage can throw you and cause you to get more questions wrong than you normally would in that area. If you think that might have been the case on the timed ACT practice test you took, and you have the time, do not hesitate to take another timed practice test. The more accurate data you have, the better you can structure your studying. Step 5: Once you know which passages you struggle with questions on, focus your reading preparation on those passages. While there are some questions that tend to appear more on some passage types than others (more on this in upcoming articles), most of the different types of questions can and will be asked about each of the four passage types. By focusing on the particular passage type you have trouble with, you'll both increase your skill at extracting information from passages you find challenging as well as familiarizing yourself with the different ways the ACT will question you (a skill which then will carry across all passage types).

Coffee tree genome sequenced Essay Example | Topics and Well Written Essays - 750 words

Coffee tree genome sequenced - Essay Example The accessibility of the absolute chloroplast genome enables an interagency spacer that can utilize genetic engineering that will improve the crop. I think the author of the article intends to report a complete sequence of the coffee chloroplast other than documenting the technological methods using new genome sequencing. The information will also compare genomic organization in lieu with phylogentic relationships of coffee with other angiosperms This article brings into focus the issue of DNA proteins in humans and genetic engineering. This is because the topic will tackle chloroplast genetic engineering of the chloroplast genome coffee. Samson et al. (342) state that coffee is one of the crucial cash crops in the world. The world consumes nearly 3 billion cups of coffee every day. The crop is second to oil in terms of foreign exchange value in many developing countries. Coffee belongs to the Rubicae family specifically of the angiosperms. The two species of coffea include Arabica and rubica . Worldwide, people use the former due to its quality and fragrance while it remains vulnerable to pest and diseases such as nematodes, coffee berry borers, fungus among others. Researchers reckon a need to improve coffee Arabica in terms of its resistance to pests like the coffea canephora that causes plenty of damage to the tree mortality and the coffee trees. Some researchers have managed to perform successful genetic coffee engineering. Some of the genetic engineering included the simultaneous cultivation of c. Arabica protoplasts in conjunction with different genes. I think the researchers acquired somatic embryos of c. Arabica through electroporation method that enabled them to combine other genes. I find that the researchers went ahead to try out different integrations in a bid to acquire a c. Arabica resistant type. It seems the efforts were in futility until they acquired

Discussion Forum Essay Example | Topics and Well Written Essays - 500 words - 1

Discussion Forum - Essay Example The advantages of working in a decentralized structure are that the system empowers employees. Having autonomy over your own decisions gives the person a feeling or sense of importance (Greiner, 1998). Also, working in a decentralized structure relieves the burden of decision making from one person to everybody else in the organization. Working in a centralized structure, on the other hand, allows fast execution of ideas. This is because decision making is left to one party, the overall head of the organization (Greiner, 1998). The difference in authority, responsibility and accountability between decentralized and centralized structures is that, in the latter, the names have individual significance instead of the decentralized structure where the phrases are more universal. By saying universal, this paper argues that authority, responsibility, and accountability are shared in decentralized structures (Greiner, 1998). Pain management documentation (PMD), comprising of assessment, interventions or intercessions, as well as reassessment, can assist provide a significant way of communication among health practitioners in order to individualize healthcare. Ordinary health institutions apply pain management documentation (PMD) as a vital pointer of quality (Samuels & Kritter, 2011). Implementation of the electronic medical record changes the presentation of PMD data for quality, as well as clinical evaluation use. Pain management documentation is frequently an objective evaluation of care given and can replicate clinical decisions. Documentation offers a key data source for knowledge creation and offers evidence required for practice liability. A majority of standard-setting institutions need PMD as a vital indicator of quality. By doing this, as earlier stated, practitioners will be able to individualize care, as well as communicate information necessary for stability (Samuels &

History musicMichael Jackson Essay Example | Topics and Well Written Essays - 1000 words

History musicMichael Jackson - Essay Example He was won more than a dozen Grammys, had multiple albums go platinum, and made millions of dollars in sales and merchandising. However, there was more to the story than just a tale of success and wealth. Michael Jackson used his celebrity to draw attention to important issues that needed addressing, as well as, humanitarian and charitable causes worthwhile of being noticed. In this, Michael Jackson’s career transcended musical genres, he evolved himself and his music to the needs and causes that were relevant to the times. Michael Jackson was born in August of 1958. He was the 7th of 9 children. Raised in a large and musical family he became the headliner of the family’s musical group, â€Å"The Jackson Five.† Unfortunately, the experiences in the earliest years of his career were some of the most difficult. The group’s father was rather strict and difficult to please. Regardless the â€Å"Jackson Five† went on to great fame and the Jackson boys became a household name to fans all over (Rolling Stone 1). However, Michael’s greatest success would come when he began his solo career in the late 1970s. In the early 1980s the music produced by Wham and The Bangles were phasing the last of the Disco dance hits out. It was here that Michael Jackson fit in to the upbeat pop of the era. He released Thriller in 1982, which changed the way people perceived the potentials of music videos for generations to come (CNN 1).These songs reflected the more fun loving, almost decadent, times that defined the early 80s decade. The lyrics reflect the fun of dance and creativity. However, while life was good in the United States, other nations around the world were struggling just to survive. Michael Jackson co-wrote â€Å"We Are the World† in order to draw attention to the famine, disease, and suffering occurring in Africa (CNN 1). It was here that much of Jackson’s work began to reflect a message of universal unity and peace, ,making changes in one ’s self, and

Death of a Salesman by Arthur Miller

Death of a Salesman by Arthur Miller Death of a Salesman by Arthur Miller. Arthur Millers Death of a Salesman, written in the years following World War II (WWII), is widely considered to be among Americas most celebrated theatrical works. Willy Loman, the plays protagonist, is a salesman whose dwindling commission can no longer afford to maintain the lifestyle his family leads. As the plot unravels, what is revealed is a contrarian depiction of the American Dream, the notion that wealth, material comfort, and the happiness they supposedly provide can be attained with hard work. The play was massively popular because it shed light on what many Americans felt was an unrealistic pressure placed on their shoulders; rather than work to be happy, Americans were working to be financially wealthy. The discontent of Willy and his descent into darkness, both moral and mental, embodied the reality of the American middle class. Life in American pop culture was a saccharine, morally whitewashed stereotype, presenting expectations to which few could live up. Pressured to work and achieve the financial successes expected in a post-war society that covets monetary excess, Willy is slowly driven into a state of emotional and mental ruin. Essentially, Willy dies doing all the right things a typical American man in the Post-War Era ought to. Scholar Gerald Weales asserts that for Miller, Willys tragedy lies in the fat that he had an alternative he did not take, [and] having chosen the wrong star he reached fro it until he died of stretching. A significant part of the plays popularity is grounded in this clash of ideology the sparring concepts of American wealth and prosperity with individuality and reality. Terry Otten writes in Temptation of Innocence in the Dramas of Arthur Miller that Death of a Salesman, probably more than any other dramatic play, provokes critical [arguments] about the viability of tragedy in the modern age and particularly in American culture. Willys descent is found in all aspects of his life, from the stock character of the nuclear family to gainful employment and the desire to achieve and earn more in life. Members of his immediate family his wife, Linda, and his youngest son, Happy, in particular reinforce the notions that drive Willy into his state of despair. Ironically, Willy can never shake himself free of the shackles he fastens to his own life by holding onto the illusory notion that he can somehow become wealthy by simply living life the way he thinks it should be lived. He still looks up to Ben, an older relative who built his wealth off African diamond mines. The only Loman to leave material gain behind is Willys eldest son, Biff, who with his work in Texas represents the agrarian icon of American life glorified before financial gain dominated the cultural zeitgeist. Consequently, Willy looks down on him to a degree, concluding that Biff can never attain the dream in his current role. Ironically, Biff is perhaps the sole character in the play to accurately observe what happens to his father, and disillusioned by Willys state, decides to seek his own path to happiness and the American Dream. The concept of the dream is something that is debilitating to Willy; the more he pursues it, the further he descends, growing increasingly delusional in his encounters with his sons. His moral fiber, a concept valued possibly even more in Protestant America than money, wanes as he takes on a mistress despite his wifes devotion. In keeping with the concept of materialism eroding the human spirit and morality, Biff, the character least associated with Willys lifestyle, is the one to gain the most from Willys suicide, a path upon which the salesman ventured in order to provide his eldest son with a life insurance settlement. At the end of the play, it is revealed that Linda has made the final payments on the house she and Willy spent their lives paying off, stating that they are finally free. Arthur Millers story of the destruction of a middle class American worker follows the structure of a classic protest play, or a stage play with a social message. Dan Vogel writes on the complexity of Willys character and the plot at large, stating that despite Willys end, his story is not necessarily a tragedy since Death of a Salesman merely tells the story of a little man succumbing to his environment, rather than a great man destroyed through his greatness; there is no question of grandeur in such a tragedy. I. R. Choudhuri notes the irony of the American Dream is what draws its audience, stating that democracy proclaims the individual in society to be free, and American democracy, in addition, approves the myth of [Willys] infinite success and happiness; and yet, these same laws and social conventions constrain and frustrate him in what he has come to believe as the birth-right of a member of the greatest open society. For Choudhuri, Millers approach to the theme of the play is drawn through undistinguished citizens, everyman-type characters whose appeal to the typical American audience is in their mundane nature. Willys circumstances are not outlandish and fantastical. He is not a Danish prince avenging the death of his father, nor is he a Moor in Venice struggling against the machinations of a society that ostracizes him. Lomans downfall is perhaps the most appealing part of the play and the component of Millers work that made Death of a Salesman so popular. Willys demise is not something out of a fairy tale it is by his own hand metaphorically and in the end quite literally. Loman cuts himself off from any help he might get from his neighbor, his sons, and his wife; unsure even of his performance as a salesman should he act the rugged individualist or play at casual charm? Willy feels deeply guilty about his past performances as a breadwinner, father, and husband. The pressure placed on Willy warps the values of the family and leaves the protagonist unsure of his identity, which leads to his destruction and ultimately made the play palatable for an audience who may very well have been a collection of Lomans.

Time Management Essay -- Lifestyle Living

'Things that matter most should never be at the mercy of thing that matter least'. We let this happen much too often. Many of us waste our time on things that are neither important nor necessary, instead of using that time for things that are significant. Time management is not only how to get more out of your time, but really how to become a better person. Time is a very hard thing to manage, because we can neither see it or feel it until it has passed. Before we can manage our time we must know exactly what time is. The dictionary describes it as, the duration of one's life; the hours and days which a person has at his disposal. How we dispose of that time is time management. It's the way we spend our time to organize and execute around our priorities. Remember just because time is intangible doesn't mean that it is not valuable. I want to teach you about the background of time management, the different styles and how to use them, and how it will change your life. Background Time management today is not as it was in the past. It has grown with time. Stephen R. Covey places time management into four generations. He feels it has evolved the same way society has. Each generation grows on the one before it. For example, the agriculture revolution was followed by the industrial revolution, which was then followed by the informational revolution. The first wave or generation is basically notes and checklist. Which really only identifies the demands placed on our time and energy. Calendars and appointment books characterize the second generation. This reflects an attempt to look ahead. The third generation is current time management field. It?s the last two generations with the ideas of prioritization, clarifying values, and comparing the worth of activities. It also includes the idea of making a specific plan to accomplish goals and activities that we determined to be of value. Because this all may be too restricting for people they turn to the previous genera tions to preserve relationships, and spontaneity. And the last generation, which is just beginning to emerge, is a different type of time management. The challenge is not to manage time, but to manage ourselves. The generation focuses on relationships and results. Time management is forever changing. We each see it in our own way. It has been used since the start of time and will only improve. Just beca... ...nd this style of time management to be the best. It incorporates the best of time management styles and combines them altogether in a very logical easy to understand manner. How Does It Change Your Life   Ã‚  Ã‚  Ã‚  Ã‚  Learning how to manage your time and successfully applying it to your life will liberate you. Really, time is the freedom and power we need to better ourselves. Once time management has become a way of life you will find your self-living a more relaxed lifestyle. Your whole life will become less stressful. While some stress is useful, it can help in focusing and increasing efficiency; too much stress creates problems. In fact, 70% of medical visits are stress related. Time management may very well improve you health. It may improve your career by helping you to be able to plan the use of your time so that tasks can be completed in timely manner, and so time is available for planning, thinking, and reflection. It will indubitably better your social life by giving you more time to spend with loved one. Also it will give you more personal time to yourselves. Because we are managing such a precious commodity that is time, the way it effects ourselves is endless and pr iceless.

Babylonian Mathematics and the Base 60 System

Babylonian Mathematics and the Base 60 System Babylonian mathematics used a sexagesimal (base 60) system that was so functional it remains in effect, albeit with some tweaks, in the 21st century. Whenever people tell time or make reference to the degrees of a circle, they rely on the base 60 system. Base 10 or Base 60 The system surfaced circa 3100 BCE, according to The New York Times. â€Å"The number of seconds in a minute - and minutes in an hour - comes from the base-60 numeral system of ancient Mesopotamia,† the paper noted. Although the system has stood the test of time, it is not the dominant numeral system used today. Instead, most of the world relies on the base 10 system of Hindu-Arabic origin. The number of factors distinguishes the base 60 system from its base 10 counterpart, which likely developed from people counting on both hands. The former system uses 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60 for base 60, while the latter uses 1, 2, 5, and 10 for base 10. The Babylonian mathematics system may not be as popular as it once was, but it has advantages over the base 10 system because the number 60 â€Å"has more divisors than any smaller positive integer,† the Times pointed out. Instead of using times tables, the Babylonians multiplied using a formula that depended on knowing just the squares. With only their table of squares (albeit going up to a monstrous 59 squared), they could compute the product of two integers, a and b, using a formula similar to: ab [(a b)2 - (a - b)2]/4. The Babylonians even knew the formula that’s today known as the Pythagorean theorem. History Babylonian math has roots in the numeric system started by the Sumerians, a culture that began about 4000 BCE in Mesopotamia, or southern Iraq, according to ​USA Today. â€Å"The most commonly accepted theory holds that two earlier peoples merged and formed the Sumerians,† USA Today reported. â€Å"Supposedly, one group based their number system on 5 and the other on 12. When the two groups traded together, they evolved a system based on 60 so both could understand it.† That’s because five multiplied by 12 equals 60. The base 5 system likely originated from ancient peoples using the digits on one hand to count. The base 12 system likely originated from other groups using their thumb as a pointer and counting by using the three parts on four fingers, as three multiplied by four equals 12. The main fault of the Babylonian system was the absence of a zero. But the ancient Maya’s vigesimal (base 20) system had a zero, drawn as a shell. Other numerals were lines and dots, similar to what is used today to tally. Measuring Time Because of their mathematics, the Babylonians and Maya had elaborate and fairly accurate measurements of time and the calendar. Today, with the most advanced technology ever, societies still must make temporal adjustments - almost 25 times per century to the calendar and a few seconds every few years to the atomic clock. There’s nothing inferior about modern math, but Babylonian mathematics may make a useful alternative to children who experience difficulty learning their times tables.

Lit short paper - Essay Example He goes on further to say that he loves not only the Supreme but also the infinitely small – the thimble, spurs, plates and flower vases.

Concerned about the financials of the company, the management has decided to reduce the existing workforce in order to reduce the annual payroll budget and thus achieve some financial relief. This in turn has triggered employee unrest and has troubled the management-union relationship at Ford. It has been suggested that the company should take to brainstorming sessions through joint management councils to sort out problems and adopt a collaborative approach to find the solutions. Collective bargaining should be patronized to appease the employees and white collar compensation should be reduced to gain their confidence. The company should divest and at the same time protect employee rights through regulatory contracts.
