Digestive system disease Free Essays

PEPTIC ULCER DISEASE Ulcer generally is defined as a breach in the mucosa lining of the alimentary canal extending from the muscularis mucosa down into the sub-mucosa or deeper structures. An ulcer is said to be acute when it is limited to the muscularis mucosa while it is said to be chronic when it involve the sub-mucosa layers of the digestive system. Peptic ulcer disease is usually about 4 cm in diameter occurring in the following part of the digestive system: lower esophagus, stomach, 1st part of duodenum, sometimes it can occur in some ectopic sites like jejunum, and meckel diverticulum AETIOLOGY AND PATHOPHYSIOLOGY. We will write a custom essay sample on Digestive system disease or any similar topic only for you Order Now Many factors has been attributed to this disease, the most common cause is an organism called Helicobacter pylori, a spiral-shaped motile flagellated bacterial which resides in the stomach. Its presence induced an intense inflammatory and immunogenic response. It also secrete many substances that affect the normal function of the stomach which include urease production, which breaks down urea to toxic compounds that affect the mucosa the organism also secrete enzymes like peptidase, lipase, mucinase that digest the protective surface of the stomach and duodenum. Moreover, when the mucosa of the duodenum are exposed to the acid been produced in the stomach then they may be breached. Also, prostaglandin produced by the stomach must be in balanced form i. e. equal amount of PGE2 and PGE1. Any increase in one without increase in the other will result in ulceration of the stomach mucosa. Some drugs have also been indicated in the development of the diseases, drugs like non-steroidal anti-inflammatory drugs (NSAID), they cause this disease by blocking the production of the protective prostaglandin, and a good example of such drugs is aspirin. Many predisposing factors have also been recognized some of which are cigarette smoking which has been taught to inhibit bicarbonate formation, it also inhibit the prostaglandin formation. Secondly, stress also predisposes an individual to the disease. Whenever an individual is suffering from the disease they always present with dyspepsia (commonly called upset stomach characterized by epigastric pain) there is nocturnal pain, nausea, sometimes heart burn. These symptoms are always on and off and long standing. Sometimes some patients presents with the complication of the disease which include perforation: the stomach or the duodenum might be perforated so that the content will pour into the peritoneum causing acute abdomen, heamatemesis (vomiting of blood), haematochezia ( passing of bloody stools) other complication include peritonitis, cancer development. Hemorrhagic complication developed as a result of erosion of the blood vessels by the acid or the secretion from the causative organism. Diagnosis This is done by proper investigation of the cause of the disease. Upper gastro intestinal endoscopy is usually carried out, barium meal is needed. For detection of the bacteria fecal antigen test of urea breath test is always carried out. Treatment The disease is usually treated with anti ulcer drugs which are acid neutralizing drugs, acid reducing agents, cytoprotective agents, and anti H. pylori agents. Examples of commonly used drugs are antacids, cimetidine, omeprazole and sucrafate How to cite Digestive system disease, Papers

TJ Nethery Essays (609 words) - , Term Papers

TJ Nethery American Political Thought 3/3/17 Henry Clay Leader of the Whig party and five times and unsuccessful presidential candidate, Henry Clay played a central role on the stage of national politics for over 40 years. He was the secretary of state under John Quincy Adams, Speaker of the House of Representatives longer than anyone else in the nineteenth century, and the most influential member of the Senate during its golden age. Known as the "Great Compromiser" Henry Clay shoed his political power and knowledge by playing a crucial role in brokering a two-part solution known as the Missouri Compromise. First, Missouri would be admitted to the union as a slave state, but would be balanced by the admission of Maine, a free state, that had long wanted to be separated from Massachusetts. Second, slavery was to be excluded from all new states in the Louisiana Purchase north of the southern boundary of Missouri. People on both sides of the controversy saw the compromise as deeply flawed. Nevertheless, it lasted for over thirty y ears until the Kansas-Nebraska Act of 1854 determined that new states north of the boundary deserved to be able to exercise their sovereignty in favor of slavery if they so choose. But in this reading I will be discussing the American System and the speech that was given to help proctor and broker this ideology. The American System was an economic plan that played a prominent role in American policy during the first half of the 19th century. Rooted in the "American School" ideas of Alexander Hamilton, the plan "consisted of three mutually reinforcing parts: a tariff to protect and promote American industry; a national bank to foster commerce; and federal subsidies for roads, canals, and other 'internal improvements' to develop profitable markets for agric ulture". Congressman Henry Clay was the plan's foremost proponent and the first to refer to it as the "American System". The main points of this speech and the main parts of Clay's thinking were set in three main Categories: An establishment of a protective tariff, the idea of having the first national bank, and the improvement of the country's infrastructure. The protective tariff would be a 20% to 25% tax on imported goods, this tax would protect a nations business from any foreign competition. Congress passed a tariff in 1816 which made European goods more expensive and encouraged consumers to by cheaper American- made goods. The establishment of a national bank would promote a s ingle currency, making trade easier, and issue what was called the sovereign credit or credit issued by the national government rather than borrowed from the private banking system. In 1816 Congress created the second bank of the United States. The improvement of the country's infrastructure, especially transportation systems, made trade easier and faster for everyone. The poor roads that were used were costly and made trading slow. Henry Clay's "American System," devised in the burst of nationalism that followed the War of 1812, remains one of the most historically significant examples of a government- sponsored program to harmonize and balance the nation's agriculture, commerce, and industry. This "System" consisted of three mutually re - enforcing parts: a tariff to protect and promote American industry; a national bank to foster commerce; and federal subsidies for roads, canals, and other "internal improvements" to develop profitable markets for agriculture. Funds for these subsidies would be obtained from tariffs and sales of public lands. Clay argued that a vigorously maintained system of sectional economic interdependence would eliminate the chance of renewed subservience to the free-trade, laissez-faire "British System."

Maximian essays

Maximian essays The overall impression I got of Maximian after reading Lactantiuss text On the Manner in which the Persecutors died, is that Maximian was a vulgar, menacing beast with a savage temper. Lactantius mentions Maximian as possessing an evil spirit and a bold attitude for doing bad deeds. The passage that helped shape my overall impression of Maximian as an evil Caesar, which I believe to be most reliable, was the passage from chapter eight. Lactantius mentions in this chapter things like Whenever he stood in need of more, the richest senators were presently charged, by suborned evidences, as guilty of aspiring to the empire; so that the chief luminaries of the senate were daily extinguished. And thus the treasury, delighting in blood, overflowed with ill-gotten wealth. After reading this passage it was very clear to me that Maximian was a very greedy emperor who would go to any lengths to get what he wanted. Another passage which states Maximians evil doings is also from chapter eight. I also find this passage to be reliable. Lactantius mentions here Add to all this the incontinency of that pestilent wretch, not only in debauching males, which is hateful and abominable, but also in the violation of the daughters of the principal men of the state; for wherever he journeyed, virgins were suddenly torn from the presence of their parents. This passage helped to shape my opinion on his savageness. In a passage from chapter thirty Lactantius gives more evidence of Maximians character which helps shape my initial impression of an emperor who is willing to go to any lengths to get what he wants. I believe this passage is very reliable because it highlights everything that I have already learned about Maximian. In this passage Lactantius brings to light that after Maximian was insulted by his son-in-law Constantine, he grew impatient and formed a plot to kill him by asking his ...

How to Use Geographic Information Systems in School

How to Use Geographic Information Systems in School Maps are effective teaching tools for geography, but when maps are combined with technology, they can become visually powerful through a geographic information system (GIS). The combination of maps and data can produce digital maps that engage students in the science of where things are. The interactive features in digital maps can help students, for example, learn how things have changed over time or to research solutions to real-world problems at any grade level. Key Takeaways: GIS in the Classroom Geographic Information Systems can produce digital maps that engage students in the science of where things are.GIS are able to manipulate and analyze data as a 3-D map of an environment.There are different GIS that educators can integrate into lessons in any content area. Systems like Google Earth and ESRI provide training, resources, and support to educators. What Is a GIS? The acronyms for tools of location can be confusing. The science of location is a geographic information science also called GIS. Location science has always been a part of geography. In contrast, a GIS (system) manipulates and analyzes data to present it spatially, as a 3-D map of an environment. This data can be collected from multiple sources. These sources can include global positioning satellites (GPS) as part of the global positioning system (GPS). These satellites relay real-time information using radio signals from space to pinpoint an exact location. In summary, the data from GPS devices is collected by GIS (systems), which is then used by GIS (scientists). Google Earth for the Classroom The most obvious example of the use of GIS in classrooms today is the use of Google Earth, an open source program that can easily be downloaded and installed for immediate use. Google Earth offers location searches and 3-D orbits around those locations. There are tutorials for educators and also topics for educators which include the writing of story maps using geographic context on the web with locations, photos, and videos. Educators can use already prepared explorer adventures with detailed information about different places to share with students. Examples of topics available using Google Voyager include: Black History Month lessons featuring locations where Black Culture has changed the trajectory of American history.Myths and Legends from Around the World lessons featuring the locations of myths from China, India, Italy, the United States, Australia, Greece, Egypt, and Scandinavia.How the Wind Becomes Electricity lessons featuring the location of an off-shore wind farm in the North Sea and the Arctic. Google Earth also offers cross-curricular activities called Warm-up Passports. Each activity is connected to the Common Core State Standards (CCSS) or content area frameworks such as the Next Generation Science Standards (NGSS). There are also opportunities to integrate Google Earth with virtual reality (VR) and augmented reality (AR) so that educators can offer students virtual field trips. Examples of Google Earth GIS Lessons and Activities The Warms include: Math Grade 5: Double (triple, quadruple) the area of this location. Write the new area in square feet. If the area of this location was divided in half, what would the size of each part be in square feet?Math Grade 7: Research the average annual temperature in this location for last year. Scientists predict that temperatures will increase by 6% globally this year. Write two equivalent expressions to represent this change.Social Studies Grade 6: Research the biggest industry of this location. What does that tell you about how people make a living there?Social Studies Grade 8: What transportation services are available in this location?ELA Grades 6-8: Identify or research one example of how humans have changed the physical environment of this location. Overall, was this change positive or negative? Use specific details to support your answer. Write a poem about the physical characteristics of this location that includes the following elements: rhyme scheme, alliteration, and stanzas. ESRI GIS in the Classroom The  Environmental Systems Research Institute (ESRI) also offers GIS to educators for classroom use. Like Google Earth, there are subject area content resources for grade levels K-12 using a GIS. On the ESRI website, teachers can use GeoInquiriesâ„ ¢, which are available without a login or download. The description for these on the ESRI site reads â€Å"short (15 minutes), standards-based inquiry activities for teaching map-based content found in commonly used textbooks.† There are 15-20 activities per topic, and many of these activities can be modified for hands-on engagement. ESRI also features educator training under the online ESRI Academy. There are course modules that demonstrate strategies for integrating GIS to support instruction and discussion. There is also a Mentors Program to support teachers. Student competitions using ArcGIS story maps are linked on ESRI’s website. Educators and administrators in the United States can request a free ArcGIS for Schools Bundle for instructional use by completing a form on the ESRI website.   Examples of Lessons and Activities Using ESRI Like the plans in Google Earth, ESRI’s detailed lesson plans are centered on a geographic context to help students connect lessons with real places. In ELA, there are lessons for American Literature in which students can explore the geographic context of Isaac’s Storm by Erik Larson, and Their Eyes Were Watching God by Zora Neale Hurston.In mathematics, students could site a water tower shared by two towns at the midpoint and determine the costs involved using the Pythagorean theorem.For a world history class, there are lessons organized around story maps for the Cradles of Civilization, the Silk Roads: Then and Now, and Early European exploration.Environmental science students can investigate marine debris, the role of ocean gyres, and how humans impact trash accumulation. Whatever the platform, educators who use GIS in the classroom engage their students in inquiry-driven, problem-solving activities that are aligned to state standards. The application of GIS in the classroom can also prepare students to consider a variety of career pathways that are in demand. GIS for Education Policy GIS helps students think critically about authentic problems by using real-time data, but there are other educational applications. A GIS can support large and small school districts in decision and policy making. For example, a GIS can provide district administrators and community safety experts the information about school buildings and surrounding areas to design and manage safety programs. In other examples, GIS data analysis of the communitys transportation infrastructure can help streamline bus routes. When communities experience population shifts,  a GIS can help districts in making decisions about building new schools or when to close old ones. The GIS can also provide school district administrators with tools to visualize patterns in student needs in attendance, academic achievement, or after-school support. Students Know GIS Students are already familiar with GIS in game applications as a blend of real and virtual environments such as Pokà ©mon Go, the mobile app which was downloaded 500 million times worldwide in its first year (July 2016). Students who play video games would be familiar with the urban environments created by GIS software, such as City Engine. Different GIS software is used for film, simulations,  and virtual reality. Finally, any student who has been in a car with GPS or has used a mobile application with interactive maps applications from Google, Bing, Apple, or Waze has experienced how the data from GPS and analyzed by GIS (systems) can blend their real world with a virtual world. Student familiarity with GIS helps their understanding of how GIS applications operate in their world. They may have enough background knowledge through personal experience that they can help their teachers become more comfortable in learning about GIS!

Islam in New York City Essay Example | Topics and Well Written Essays - 1000 words

Islam in New York City - Essay Example Knowing these objectives in advance, I recognized the willingness of the Center to provide a comprehensive and immersive experience for the pursuit of truth for its own sake. Since the Center is devoted to enlightening the public, I knew they would be open to providing instruction and first-hand experience. In addition, I gained much from not only visiting the mosque itself, but also touring the other parts of the Center, which are an asset to Muslims living in Manhattan. These experiences represented an opportunity to apply what I have learned about the history, doctrine, and practices of Islam in the classroom. Before visiting the Center, I phoned the front desk to inform them that I would like to visit the Center, its mosque and other parts. They quickly agreed after realizing that my visit was for the purpose of education. I came on a Sunday, which is a day that the Center offers classes for children and adults. I did not know that these classes are open to non-Muslims as well. I was impressed by the inclusiveness of the mosque, especially in the fact that every student (regardless of their religious affiliation) learned Qur’anic Arabic, prayers, and general Islamic teachings touching upon different aspects of life. If I had more time and had planned to take one of these courses ahead of time, I would have. I learned that the Center is in the final stages of building a full-time Islamic school by seeing the final touch-up work on the building. Before coming to the mosque, I knew to respect the thought that a Muslim should wear clean, loose-fitting clothes that cover ankles and wrists. Respectful of this tradition, I approached the mosque in the morning. The doors leading up to the mosque were very large and constructed from a hard material. I noticed immediately that the mosque itself was very large and stood apart from the rest of the building. I understood why this might be because, throughout history and still today, mosques serve as both social a nd political centers for Muslims. The integration of religious and political life means that the same building serves two very essential functions, which was even more reason to be respectful when visiting the site. When I entered the mosque portion of the Center, I immediately noticed the shoe racks against the wall to my left and my right. I thought this was logical, given the need for worshippers to put away their shoes or slippers to pray. I am still unsure why specifically Muslims remove their shoes when they enter a mosque: whether it is because of hygienic reasons to protect the rugs in the prayer chamber or because it is holy ground and a sign of admiration for the surroundings Regardless, I removed my shoes and continued into the reception area of the mosque. I noticed also very classical vases and pottery that was symbolic of Islamic history. In some of these pots and vases were plants that seem to have come straight from the Middle East. I saw this as an acknowledgement o f Islam’s long and storied history in the arts, which I recognized as overall very important the Center as far as it is concerned with promoting knowledge and awareness of Islamic history. Also in the reception area was the Lillah box, which collects charity given voluntarily. The Lillah represents more giving than the Zakah, which is obligatory giving. The proceeds from the Lillah

Verbal and nonverbal communications are important to send and receive messages effectively during conversations. Task and maintenance roles are a way that groups are able to achieve their desire outcome The group that I will describe is a special task force group which I belong too at a former employer. The group was composed of five members. The size of the group was adequate. The purpose of the group was to brainstorm ideas for new products. The group was extremely effective. The first attribute that made the group so successful was the presence of a tremendous team leader. The team leader had superb communication, leadership, and people skills. She made everyone feel that their opinions and input were valuable. All the team members got along well and they supported each others ideas. One of the primary reasons that the group was so effective was due to the fact that the group was able to achieve synergy. Synergy occurs when the whole is greater than the sum of the parts. Three cha racteristics that made the team effective were leadership, effective verbal and nonverbal communication, and clearly defined tasks and maintenance roles. The team leader was very flexible and from time to time she let the other members take charge of the group to help them develop their leadership skills. This enabled other team members to develop their leadership skills. Everyone on the team was very responsible, attentive to details, and they delivered their work tasks on a timely manner. Absenteeism among team members to meetings was minimal and rarely would a team member arrive late. Team meetings were held during and after work hours. The meetings after work hours were informal and its purpose was to socialize more than to do actual work. The team
