Making a grand entrance into Europe in the mid 1300s, the Black Death took almost one third of the continents population, with numbers exceeding twenty million people. The devastating epidemic sprung from a strand of the Bubonic plague that infected twelve ships docked in Messina, venturing from the Black Sea. When docked, majority of the sailors living on the boats were found to be dead, those who managed to say alive did not last much longer. The drastic change in population caused significant changes for the citizens of Europe as they entered the Late Middle Ages. Gruesome symptoms began to take over the internal operations and external appearance of the body. Symptoms spread in a fast manner, making the plague one of the most contagious diseases to ever attack the world. Once infected, it was likely to experience headaches, fevers, chills, and eventually fatigue, all normal symptoms of any day-to-day virus. After developing the basics, symptoms got a little more unique and developed into an aching of the entire body. On top of all of these, the patient would then notice swellings which consisted of hard, painful, and burning lumps on the neck, under the arms, and on inner thighs. Without much time passing, these swellings turned into large black growths that would then begin to ooze fluids, such as pus and blood, at a random rate. These extreme symptoms would soon become fatal due to the internal bleeding most were known to cause. Moments before the plague took over the body one final time, it created a unique stench that stemmed from differe nt parts of rotting body. The most common way this dreaded disease was spread throughout Fourteenth Century Europe was through a series of flea bites. Don’t waste time! Our writers will create an original "The Black Death Worst plague in history" essay for you Create order These fleas, having ingested plague infected blood from their hosts would often attempt to feed on other victims, invariably injecting some of the infected blood into its new host, resulting in the Bubonic Plague. Once infected, one could infect others through airborne pathogens in close quarters of those who remained healthy up until that point. Due to the rapid transmission rate, the few doctors that dared to come face to face with the Black Death wore a beak-like mask filled with aromatic items to fight off the deadly disease. Fourteenth Century Europe was devastated. Religious, social, and economic riots took place and left a permanent mark in European history, this including the end of feudalism in Europe. The citizens decided that tomorrow remained unpromised, so they lived each day in the moment. The population decrease brought mostly favorable results to the surviving people in Western Europe. Land was plentiful and the innovation of labor-saving technologies became the first major movement after the plague. The Black Plague will not be forgotten anytime soon. As one of the worst diseases to ever create an epidemic of this severity, the Black Death remains engraved in the history of Europe along with the troubles and upheavals that came with it.

Tissue perfusion, blood flow through body tissues is involved in the delivery of oxygen and nutrients to and the removal of wastes from the tissue cells, as well as gas exchange in the lungs absorption of nutrients in the digestive tract and urine formation in the kidneys. The rate of blood flow to the tissues is almost exactly right to provide proper function. 1. Lipid soluble molecules such as respiratory gasses diffuse through the lipid bilayer of the endothelial cell plasma membranes. Small water soluble solutes such as amino acids and sugars pass through fluid filled intercellular capillary clefts or fenestrations. Some larger molecules such as proteins are actively transported in pinocytitic vesicles or caveolae. 25. Hepatic portal vein, Superior mesenteric vein, Splenic vein, Inferior mesenteric vein. In most circulation, the blood goes from the heart to the aorta to the arteries, to the organ or tissue, to the veins and back to the heart. In a portal circulation, the blood goes from the heart to the aorta to the arteries, to the organ or tissue, to a vein, then to another tissue or organ BEFORE it goes back to the heart. An example of this is the blood that goes through the anterior mesenteric artery to the small intestine, goes through the mesenteric vein to the hepatic portal vein, and to the liver, before it returns to the heart. This is because the blood coming from the intestines has a lot of sugar that it absorbed. The body tries to keep the level of sugar in the blood the same at all times. So, the blood goes to the liver, where it stores some of the sugar, before it goes back to the heart and through the rest of the circulation. Then, in the middle of the night, when you haven’t eaten anything in a while (and the level of sugar in your blood is low), some of that sugar that was stored in the liver is released back to the blood.

Strengths And Weaknesses Essays - Educational Psychology

Strengths And Weaknesses Everyone has strengths and weaknesses but as a child, it's hard to deal with your weaknesses. It's not until you grow up and realize that you have to use your strengths to overcome your weaknesses. Combining logic with technology can be a useful tool. For me it was the way to overcome my disability. Early on in my education I encountered learning disabilities. These learning disabilities included reading, spelling, grammar, and difficulty in time writing reports. These learning disabilities have frustrated me. I wondered Why couldn't I do this? I knew that I had the intelligence, but I just could not finish the assignments. I would then become angry. My anger sometimes led me to break pencils and throw them across my room. The basis of my learning disabilities, I discovered, was in transferring my thoughts and ideas from my head to paper. Reading was also a challenge for me in the early grades. I never had trouble understanding stories themselves; but when I had to answer questions a bout what I had read, I often had difficulty formulating an answer. Another major issue I had was the slow pace of my work. In elementary school I usually didn't finish my homework until 10 o'clock at night. Other students in my grade were finished by 7 o'clock. Although this was difficult for me to deal with, I did not let it stop me from completing my homework. Originally I felt sorry for myself. I believed that I would never overcome these problems. This led me to complain how unfair it was. Perhaps, I thought, someone did not want me to succeed. Word processing was a huge benefit to me in overcoming my learning disabilities. Before I had a desktop computer I had great difficulty writing reports. This was due to the fact that I had to type up my reports using a typewriter. After every sentence, my mother had to check my spelling. Due to this my progress was at a snail's pace. Also, throughout elementary school, and into the beginning of high school, I had illegible notes. Then, a t the beginning of junior year, I purchased a notebook computer. This aided me greatly. I could now actually take notes since I could type far faster than I could write. The computer enabled me to read the notes, which I had taken because my handwriting was often not legible. Finally I came to the realization that everyone has strengths and weaknesses and that I had to learn how to overcome my weaknesses and focus on my strengths. Logic has always been one of my strengths. I began to understand the technology, which had so helped me. Everyone has strengths and weaknesses but as a child, it's hard to deal with your weaknesses.

Auto Pact essays

Auto Pact essays In May of 2000 the World Trade Organization (WTO) ended the Canadian made Auto Pact. The Auto Pact was an agreement constructed by Pierre Trudeau in 1965 that allowed companies to bring auto parts and vehicles from anywhere in the world into Canada without any tariff, but with two conditions. One condition was a requirement of commitment to jobs in Canada, manufacturers had to produce one car in Canada for everyone they sold. They also had to maintain a Canadian Value Added (CVA), which basically means no depreciation on Canadian made machinery and that parts in assembly were also made in Canada. Automotive trade markets are among the most open in the world. They maintain no tariff barriers. This treaty kept North America happy however; the overseas companies were left with the shorter end of the stick. This caused the fall of the Auto Pact. The Auto Pact is too important to Canada, and Canada will suffer extreme losses.(reword) (give the main points) The 1965 Auto Pact is Canadas most successful trade agreement. We should be kissing his ass, says the wise yet youthful Jon Cooper as he refers to Trudeaus ingenious scheme. It is a building block of Canada. Since signing the Auto Pact, the Canadian automotive industry has enjoyed enormous growth. Production and automotive manufacturing employment have increased 200% and automotive shipments grew from $2.2 billion in 1964 to $70.5 billion in 1995. The main two focuses of Trudeaus were exports and employment. Trudeau increased the automotive sales from a once scarce Canadian industry into its top export. His other concern, creating employment doubled. Without the Auto Pact enforcing these numbers they will fall. The Canadian Auto Workers (CAW) president Buzz Hargrove said at the Caw Joint Council meeting in December 2000 that the Auto Pact was: A trading pact that has meant so much to the growth of the...

Alternating Current and Direct Current Essay Example | Topics and Well Written Essays - 2000 words

Alternating Current and Direct Current - Essay Example The paper shed light upon several advantages and disadvantages of both DC and AC, how AC is converted into DC has also been discussed in this paper. It is important to note that DC is easier to analyze and has a plethora of other advantages but DC’s inability to convert different voltages is a big con because of which AC is used more widely then DC. However, the modern day electricity devices require DC so they come with automatic converters that instantly convert AC into DC. For transferring current over a long-distance DC is used because it is cost-effective but otherwise AC is used, another difference is that people in North America use AC and people in European counties use DC. These were some of the advantages, disadvantages and the most important differences between alternative current and direct current. Alternative current won over direct current in the 20th century when it was chosen over DC because people considered it more reliable, it had very few risks and this is why it was chosen as the standard current in North America, DC on the other hand had several major issues which were later sorted out and fixed. After fixing the major issues with DC several European countries chose it as their standard current, these days DC is being used in some of the elite European countries. It is necessary to have a circuit in order to distribute electricity. A circuit is usually made up of two wires which lead up to a device which uses electricity. In the case of alternating current, one of the two wires is positive and the other is either neutral which is also known as ground or negative, the two wires take their turns which enables sending electricity. In direct current the process works a little differently, the polarity in DC is always the same unlike in the case of AC where in polarity differs, in a DC circuit one wire is negative which means the other is sending electricity and is positive, the negative wire does not send electricity in a DC circuit. T here is no cyclic change and hence no hum in a DC, it is a fact that DC scores over AC in long-distances. In high-voltage transmission also DC is preferred because in AC a lot of electricity is lost, in DC less wastage takes place and this is why it scores over AC. AC scores over DC when it comes to converting DC into AC, it takes a lot of money to do that and it is not advisable to do so. DC should ideally be used only for long-distance transmission and AC in all other circumstances. Heating elements and light bulbs hardly care if the electricity supplied to them is DC or AC but it is very important to note that most modern day electrical gadgets require DC to work effectively. These days a transformer is used which consistently converts AC into DC for the devices to work effectively. In countries like Canada and the United States AC outlets have a voltage of 115 V and this is at 60 Hz. In European countries this is much different; most countries use 220 to 240 V which is about 50 Hz. It is also important to understand how peak voltage works, 115 V AC power usually has a peak voltage which is in the region of 163 V. Home and office electrical outlets are delivered electricity when the terminal has one hot and one neutral terminal. AC voltage is preferred by several people because a transformer is used to convert it into DC and it is very easy and a reliable source of getting direct current. A transformer consists of two inductors, the loops and turns present in these inductors are very different from each other. The number of turns usually determines the ratio of primary to secondary voltage. Electric generators have been made to produce alternating current, they can also produce DC but this can only be done by using a rectifier. A rectifier is made up of diodes which are also the most important part of a rectifier; the main use of a diode is that it allows the current to flow only in a single direction. DC power can also be converted into AC power; this can be done by using an inverter. Heating and arcing are two problems which are involved in producing AC and DC, alternating current can be generated at a much higher voltage than DC and the best part is that there will be fewer problems like heating and arcing. It is

Management of Human Resources (HRM) Essay Example | Topics and Well Written Essays - 1000 words

Management of Human Resources (HRM) - Essay Example Without such kind of mechanisms, some managers, as perfect as they are have failed in their functions, especially in initiating internal change of an organization and determining appropriate solutions to the problems existing in the HR domain. Examples arise from the U.S firms moving to operate in China and vice versa, which have resulted either in a failure in their external markets or a success to those that effectively managed change in the human resource (Jackson et al, 2012). A manager like any other human resource is a vital and valuable asset used to enhance organization performance and success. In other words, the organization â€Å"believes in the employee’s element as a strategy to drive innovation, productivity, and sharing price through workforce mobilization towards organization success† (humanresourcesexplained.com, n.d.). The HRM therefore performs various functions to ensuring proper policies and programs are developed and administered, according to the designed plan in mind, to enable effective utilization of the human resource, while steering them for individual development into higher performance and leadership positions in future. In general, HRM is a broad scope â€Å"focused on people in the organizations, and as a designed management system to enable human talents to be used efficiently and effectively in accomplishing organization goals† (vmouonline.in, n.d, p.2). HR functions involve decision making in the scope of their activities (e.g HR planning, selection, development, rewarding, appraisal, and safety among others), such that the objectives intended for the organization are met, and the HR brings up competent managers and leaders to lead the organization in various fields. Ensuring competent managers are in place The recruitment and selection function of the HR is essential to ensure the right personnel fit for an existing position or able to perform certain tasks required in leadership selected fro the benefit of the benefit of the company. In the recruitment process, HRM is responsible for attracting suitable human resources, availing the job description and candidate specification and bringing a job opening to the attention of the targeted individuals (Kyriakidou, n.d). Hence, candidate with management expertise or those satisfied can apply for the job so that organization invest in their human capital, acquire their talents and utilize them in leadership. In selection stage, modern organizations use interviews, references, and in advanced cases with the help of Biodata and Psychometric testing (Braton and Gold, 2007). In the end the HRM can acquire managers and employees with the right skills for the job, one wiling to learn new tasks and capable of adapting to the changing conditions and cultures of the organization. One of the HR function is managing and developing identified talents in organizations. The HR specialist engage in coordinating the new hire orientations, providing train ing, instruction and in house workshops, and conduct needs assessment based on the employees’ identified skill sets (Mayhew, 2013). HR can hence determine potential skills based on the pool of employees they manage and decide to select them for advanced training. Different employees have different capabilities and it is the role of HR to tap into and develop the exceptional talents, whether in leadership
