Weapons of the American Civil War Essay - 1654 Words

Weapons of the American Civil War Amongst the most lasting of factors stemming from the Civil War are the weapons that were developed. Before the Civil War, the weapons used were highly unreliable, and were not advanced enough to provide the needed defense for a young nation such as our own. Innovative minds created many interesting ways to demolish their enemies without ever having to fire a shot or go into full combat through different types of bombs that were in disguise. Among the advancements in the Civil War were the torpedo, the carbine rifle, the minie` ball, several models of rifle-muskets, rocket launchers, rocket bombs, Greek Fire, and a wide array of other secret weapons. Torpedoes were quite possibly the most†¦show more content†¦A few years of development and a patent later, the minie` ball was ready for combat. In the 1850s, James H. Burton, a master of arms, made a few alterations such as slightly lengthening the bullet and thinning the walls of the hollow base. These alterations made the minie` ball much easier and cheaper to mass-produce; this is what was used by the blue and grays out on the battlefields. The Union soldiers were more likely to carry the U.S. Model 1861 Springfield Rifle-Musket than any other weapon. These guns were not the easiest or most convenient weapons even if they were the most common. The Model 1861 was a .58 caliber gun, was 58.5 inches long, and weighed in at a heavy 9.25 pounds. This rifle was nicknamed The Widow Maker. This nickname was made with great thanks to the minie` bullet which was an integral part of this rifle-musket. The combination of the rifle-musket and the minie` bullet forever changed the face of warfare; thus because for the first time ever, men could aim at a distant target, and have a decent chance of hitting it. This luxury allowed the gun-bearers to hide in a safe place, yet still be able to knock down their target.

What organizations, ideologies, and leaders did Africans create and engage in the 20th century to promote and advance their liberation? [Abstract] The 20th century composed of many organizations ideologies and leaders helping to promote and advance liberation both in America and worldwide. These different entities worked to defy the social structure filled with aspects of conservatism and oppression and rather upheld the Africana sense of governance and encouraged socialism in terms of a more broad and pervasive perspective on civil rights. Additionally, many leaders, Nelson Mandela, MLK, and Madame C.J.

These groups and people made lasting impacts in nations worldwide that are still prevalent today. When analyzing the sixth framing question, the conceptual categories of social structure and technology are evident. Organizations such as the Universal Negro Improvement Association and the African Blood Brotherhood contradicted the social structure at the time and defined new governance for the African people. Leaders such as Madame Walker, MLK, Nelson Mandela, among others assisted in defining new governance as well. Also, an important aspect of the 20th century was the incorporation of technology, also a conceptual category, into persuading the public about the necessity of change within the generation, and for upcoming generations. Parallel to the organizations and leaders, the ideologies that c ontradicted themselves progressed the Africana culture in its entirety. Liberalism and conservatism, while differentiating, showed the public that while ideologically there were discrepancies, within the construct of society, these divergences were not adequate reason for physical violence. Primarily, the two listed organizations were essential for the Africana people to advance and promote their liberation.

Nutritional Requirements of Individuals with Dementia free essay sample

Understand and meet the nutritional requirements of individuals with dementia. Outcome 1 1) describe how cognitive, functional and emotional changes with dementia can affect eating, drinking and nutrition. Cognitive behaviour is dysfunctional emotions and behaviours caused by damage in brain affecting part of the brain responsible for memory and all that we learn from birth- how to talk, eat etc. This means that person with dementia can forget how important it is to eat and drink. They also may lose sense of hunger and thirst. It can become problem putting client’s health at risk. Functional change is losing ability to remember how to eat using cutlery. Instead, some people find easier to pick up food by hand, so finger food should be provided. This might be a good way to avoid confusion and distress for a client. If person finds it easier food should be laid out for a client promoting their dignity. We will write a custom essay sample on Nutritional Requirements of Individuals with Dementia or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Emotional change can be negative emotions about the confused state when individual may not understand that there is something wrong, but behaviour of others may lead them to feeling something is wrong, which often causes stress to individual with dementia. Explain how poor nutrition can contribute to an individual’s experience of dementia. Poor nutrition can make the symptoms of dementia worse, increase risk of more frequent infections requiring use of antibiotics. Malnutrition also affects immune system making it difficult to fight an infection. Effects of poor nutrition: * Higher risk of infection * Reduced wound healing * Dermatological problems * Constipation * Disturbed sleeping pattern * Weight loss/gain 3) outline how other health and emotional conditions may affect the nutritional needs of an individual with dementia. It is more likely that as well as dementia older elderly are more likely to develop other chronic illnesses and therefore will have specific nutritional needs. Nutritional requirements Energy requirements decline with age, particularly if physical activity is restricted. However, requirements for protein, vitamins and minerals remain the same, so it is imperative that food choices are nutritionally dense, supplying a rich supply of nutrients in a small volume. Fat There should be no restrictions on the input of fats if a client: * Has suffered weight loss. Has a very small appetite * Is very weak Fibre Eating cereals, fruit and vegetables as a part of balanced diet will help clients who have bowel or constipation problems. Sugar Many elderly people have high sugar intakes. If the rest of the diet contains lots of foods from the main food groups, there is no reason to limit sugar intake. In fact, if weight loss has occurred, sugars may be recommended to meet energy requirements and to aid weight gain. Iron Anaemia is common in elderly and can be caused by poor absorption, certain drugs and blood loss. Iron intakes can be met by having red meat and non-meat sources every day. Absorption is maximised by consuming vitamin C-rich foods at the same time, such as a glass of fruit juice or fresh fruit or vegetables with each meal. Zinc For clients with pressure ulcers intake of Zinc is vital for body’s natural ability to heal wounds. (Can be found in meat, pulses, wholemeal bread and shellfish) Calcium Consuming calcium rich products on a daily basis can slow down loss of calcium in bones, which starts at the age of 30 and accelerates considerably in later years. Calcium-rich foods (milk and dairy foods) should be eaten every day. Vitamin D Vitamin D is needed for calcium metabolism and its deficiency in elderly people can lead to bone softening and distortion. Many elderly people also have limited exposure to sunlight (this vitamin can be made through the action of sunlight on the skin). B Vitamins Intake of B vitamins may be low in this age group if appetite is poor and the diet is not rich in vitamins and minerals. To help prevent this, foods from all food groups must be consumed every day. Water Taking an appropriate amount of water (approximately 2 litres) each day will: * Aid digestion * Maintain effective urine flow * Stop dehydration * Keep hair and skin healthy * Maintain good kidney function Emotional and psychological effects that might affect nutritional needs of an individual with dementia: * Apathy * Confusion * Memory loss * Delirium * Disturbed sleeping pattern * Mood * Depression Physical effects that might affect nutritional needs of an individual with dementia: * Physical discomfort (bad fitting dentures or person is wet) * Lack of exercises. Damage to the brain * Difficulties with chewing and swallowing * Changes in food preference * Loss of taste * Constipation * Living alone 4) explain the importance of recognising and meeting an individual’s personal and cultural preferences for food and drink. It is important to recognise an individual’s personal and cultural preferences to food and drink as this can make people feel like they are respected and included. This will encourage individual to eat and drink, but also it will increase their emotional and physical well-being. People may have different views about foods depending on their cultural background. Providing range of familiar foods can help make individual feel at home, safe and welcomed. As well as providing nutritional value food and drink also play a significant role in culture and rituals. For example, Chinese people eat with chopsticks. Some people like to have a glass of wine with their meal. People from different cultures can only eat certain things as reason of their religion or believes. | | All this information should be included in individuals care plan under life  history. 5) explain why it is important to include a variety of food and drink in the diet of an individual with dementia. An individual with dementia has the same needs and rights as someone without dementia. Eating is basic human function and need. The type of food people eat affects their health and quality of life. People who eat poor diet get sick more often and recover from injury and illness more slowly. Outcome 2 1) describe how mealtime cultures and environments can be a barrier to meeting the nutritional needs of an individual with dementia. Possible reasons for malnutrition in residential or nursing homes: * Underlying disease or illness * Loneliness or depression * Monotonous menu * Unfamiliar foods * Inappropriate textures * Inflexible meal times * Lack of snacks and nourishing drinks * No choice of portion size * No monitoring of food intake and weight loss * Insufficient staffing to help with feeding * General lack of fresh foods * Dull and bland food 2) describe how mealtime environments and food presentation can be designated to help an individual to eat and drink. Clients with dementia are reassured by a calm and regular routine. Meals should be relaxed and unrushed, allowing plenty of time. Prevent any distractions, such as television or radio. Many individuals prefer to eat in company, so creating a social environment for meal times can help. However, there can be others who like to eat alone, so it is important to find out each client’s likes and dislikes. Presentation of food is very important. Clients will eat better if food looks more tempting, smells nice and looks delicious.

Mechanical Energy Essays - Energy Development, Chemistry

Mechanical Energy Have you ever wondered how a jet aircraft lifts its tremendous weight off the ground, or what gives a runner the stamina to reach the finish line in a race? In order to answer all these questions we must talk about the transformation of one sort of energy into another. The jet aircraft gets its power from jet turbines. These powerful jet engines create a high-pressure stream of very hot gases that push the aircraft forward as they leave the engine. This is an example of heat being transformed into movement. This is sometimes described as Mechanical Energy. However, this transformation could not take place without the fuel that the aircraft gets within its wings or fuselage. Fuel is considered a chemical energy. This diagram shows how the jet engine acts as energy to lift the aircraft off the surface of earth. Fuel can take the form of gases, solids or liquids. When fuels combine with oxygen from the air, they release their stored energy as heat. We recognize this process as burn ing. The individual relies on food for fuel which contains energy-giving substances that our bodies can store until we need this energy to use our muscles. When we do use our muscles within us, we may not always be sure that heat is given off. Our bodies do not burst into flames but the perspiration on our skin is a clue to what is happening. The movement of the windsurfer has a different explanation. The windsurfer is propelled along by a sail which collects mechanical energy from the winds that sweep along the water. This energy has been produced by the sun which warms the earth's surface and sets the air above in motion. The sun's heat comes to the earth as a form of radiant energy. When the heat reaches the surface of the earth, it causes the land or seas to rise in temperature. The sun is very hot. Infact, the center of the sun can reach temperatures of up to 27 million degrees Fahrenheit. This is because of another kind of energy reaction where new substances are continually being created as others are being destroyed. This reaction is known to us as the Nuclear Reaction. Today we are trying to imitate this reaction in improving our energy supply. Scientists have calculated that the sun has enough fuel to go on producing energy at its present rate for about five billion years. On earth man-made nuclear reactions are used to produce a form of power we know as electricity. Electricity can be transformed into other kinds of energy such as heat, light and radio waves. Humans have also used the idea of nuclear reactions as a type of weapon. We call this powerful weapon the Atomic Bomb. Electrical energy can also be used to produce laser beams. This involves energy being concentrated to a specific narrow point where the impact of so much power creates heat able to cut through metals.

Taking Blood Pressure Measurement

Taking Blood Pressure Measurement Introduction One important lesson in medical education is how to measure the vital signs of life such as blood pressure. For one to understand how to perform this accurately, it requires attention to detail, correct technique and careful listening (Kier, Wise and Krebs, 2003). The term blood pressure is taken from the fluctuating pressure that blood applies against arterial walls as the heart alternately expands and contracts.Advertising We will write a custom essay sample on Taking Blood Pressure Measurement specifically for you for only $16.05 $11/page Learn More This pressure is useful in that it can be used to assess the condition of the heart, amount of blood forced out of the heart at contraction, condition of the arteries and to some extent the viscosity and volume of the blood (Kier, Wise and Krebs, 2003).  The blood pressure of an individual is measured in the brachial artery of the arm at the antecubital space (See Figure I). Initially measuremen t should be performed on both hands as there is normally a 5-10mm difference (Kier, Wise and Krebs, 2003). After this subsequent readings should be continued on the arm with higher pressure. The maintenance of blood pressure is mainly the result of two related factors. The first being the heart which is responsible for pumping blood round the human body. The human heart reportedly contracts almost 100,000 times daily forcing blood through the aorta and the entire range of blood vessels (Kier, Wise and Krebs, 2003). A strong pump is essential to make sure that the blood flows and the pressure does not drop. In this report a discussion will be presented on how to provide a computer mediated lesson to teach how to measure blood pressure to a group of students. In addition to this a suitable method of evaluation will be selected to assist the instructor assess how well the learners understood the topic. Also to be discussed in the report is the role and effectiveness of one authoring to ols that will be used in presenting the learning material to the learner’s. Method of Evaluation The purpose of evaluation of a learner is to establish whether what was taught has been understood (Reeves Hedberg, 2003). It is reported that the most important function of evaluation is review of what has been presented to the learner. It is hoped that through reviewing the highlights of what was learnt the learner can recap and develop a sound understanding of the concepts taught (Reeves Hedberg, 2003). Prior to taking an evaluation it is important that the learner review the text or the material that was used in instruction.  Another crucial but sometimes underutilized function of evaluation is needs assessment (Reeves Hedberg, 2003). In the case of taking blood pressure it may be crucial that a needs assessment form part of the evaluation process depending on at which stage the learners are in the course.Advertising Looking for essay on education? Let's see if we can help you! Get your first paper with 15% OFF Learn More In this case a practical needs assessment evaluation may need to be undertaken to ensure the learner is fully conversant with what is required to successfully carry out the blood pressure test. This would is sometimes known as a formative evaluation. A more detailed test may require a learner to carry out the actual tests and record results. Such an evaluation is more rigorous and may be classified as a formative evaluation. As indicated above the evaluation methods used can either be formative or summative. In the case where formative evaluation is used the goal of the teacher is to establish the progression of students towards meeting the learning goals. In this case this suggests progress in the class towards learning how to complete the test and its relevance (Oermann and Gaberson, 2009). On the other hand where summative evaluation is used the goal of the teacher will be to establish the student has com pleted the set of goals required within the rotation such as a term or semester (Oermann and Gaberson, 2009). This position shows clearly that the assessment will depend on the duration for which this task will be covered and whether it will be part of a set of tasks that are completed within a length of time. However, if the task is a one off affair a formative evaluation will be appropriate. This may include a brief set of questions to ascertain whether the learners were paying attention during the lecture. Some questions on what materials are required and the main points of how to take a blood pressure reading could form the evaluation. Instructional techniques In the selection of an appropriate instructional technique it is important to know when a specific instructional technique is best applied. Given that that this lesson will be computer mediated it appears a lecture will be the most suitable technique for providing the lesson or lessons. This is because lectures are best ap plicable to a lesson when the instructor intends to give an overview of a greater issue (Sharma, 2007). The lecture can be taken to e appropriate as it allows the instructor a longer time to discuss the issue at hand. As with the case of taking blood pressure a lecture or series of lectures is important as it will help put the issue into its correct perspective. As with any illness it is necessary to understand causes and possible circumstances to avoid. A lengthy discussion such as this would require ample time. In addition to time to speak the instructor can make use of the computer or information technology to make the lecture more interesting (Sharma, 2007). This is because a lecture is also useful when the instructor wants to aid or supplement student reading.Advertising We will write a custom essay sample on Taking Blood Pressure Measurement specifically for you for only $16.05 $11/page Learn More In such cases an instructor can ask the class to read on a specific topic and later prepare a brief lecture or series of lectures to expand on the materials that the learners covered in their individual reading.  A lecture is also useful when the instructor needs to provide the learner with background information on the topic. In such cases the learner will then be able to go about the study of the topic more intelligently (Sharma, 2007). Without an appropriate introduction it is sometimes impossible for a learner to determine how deep and wide to study the desired subject. However, for introductory purposes a lecture can be very appropriate.  Another reason why the lecture may be an appropriate mode of instruction is because the instructor may want to allow the students more time for in depth study or assignments or other tasks (Sharma, 2007). Given that this task was to be accomplished in a semester of a nursing course it is likely that the student would be required to handle some assignments after completing the lesson. It is no t uncommon for learners to be given tasks such as assignments to assist them gain deeper understanding (Sharma, 2007). In such a case therefore a lecture will be useful in acting as a suitable eye opener and providing descriptive boundaries to consider when doing further reading. A lecture can also be very useful when the instructor wants to arouse interest in the learner. Introducing a new and perhaps complex article is likely to be difficult and complicated. However, with the use of an interesting well arranged and presented lecture a student can be aroused and enticed to enjoy an otherwise difficult or complex topic (Sharma, 2007). In addition to the above the instructor may want to use the opportunity of a lecture to teach terms associated with the topic or clarify common misconceptions. Such occasions are best dealt with when the instructor opts to give an audible explanation. In addition to providing information this also acts as an opportunity to allow learners to ask questio ns about the topic. Learner Activities Since the subject matter in this case is related to medical studies we will use some information from medical studies to guide us in selection of learner activities. It has been reported that medical studies are best learnt when the learner s are motivated (Distlehorst, Dunnington and Folse, 2000). It has bee suggested that an interesting activity that may captivate the learner’s upon completion of the lecture is a practical opportunity to attempt to take the blood pressure and listen in on the different phases. Blood pressure phases are identical to the phases of the pulse and an opportunity to physically perform the examination should be fairly exciting to most of the students (Kier, Wise and Krebs, 2003).Advertising Looking for essay on education? Let's see if we can help you! Get your first paper with 15% OFF Learn More In addition to that another activity that the learner’s can participate in where the course is being offered near a clinic is an arrangement to walk in at scheduled times and assist the nurses in performing the examination. This activity is thought to be useful as learning is thought to be efficient when there is feedback to the learner (Distlehorst, Dunnington and Folse, 2000). Such an opportunity is bound to be efficient as there is immediate feedback each time the student does something the right or wrong way. In addition to the above two the normal activities such as assignments may also be used to follow up on learning and even for evaluation of learning. Computer Mediated Learning Authoring Tool For the purposes of preparing a lecture or series of lectures on how to take blood pressure measurement a multimedia authoring tool such as PowerPoint may be used. Such tools allow the user to bring together various multimedia components to bring together a powerful presentation (See Figure I). For example on may incorporate pictures, audio and tables or charts and even video to make the presentation of a lecture very interesting (Stroman, Wilson Wauson, 2008). PowerPoint is typically called a slide show program and its main feature is it allows the preparation of a presentation one slide at a time or in a linear fashion. Each slide can allow the presenter to attach any of the multimedia content earlier mentioned and may allow some degree of branching (Stroman, Wilson Wauson, 2008). The software was selected because it is readily available and fairly easy to learn. References Distlehorst, L. H., Dunnington, G., Folse, J. R. (2000).

Why Fossilized Shark Teeth Are Black

Why Fossilized Shark Teeth Are Black Shark teeth are made up of calcium phosphate, which is the mineral apatite. Although shark teeth are sturdier than the cartilage that makes up their skeleton, the teeth still disintegrate over time unless they are fossilized. This is why you rarely find white shark teeth on a beach. Shark teeth are preserved if the tooth is buried, which prevents decomposition by oxygen and bacteria. Shark teeth buried in sediments absorb surrounding minerals, turning them from a normal whitish tooth color to a deeper color, usually black, gray, or tan. The fossilization process takes at least 10,000 years, although some fossil sharks teeth are millions of years old! Fossils are old, but you cant tell the approximate age of a shark tooth simply by its color because the color (black, gray, brown) depends completely on the chemical composition of the sediment that replaced the calcium during the fossilization process. How to  Find Shark Teeth Why would you want to find shark teeth? Some of them are valuable, plus they can be used to make interesting jewelry or to start a collection. Plus, theres a chance youll find a tooth from a predator that lived 10 to 50 million years ago! While its possible to find teeth just about anywhere, your best bet is to search at a beach. I live in Myrtle Beach, so every time I go to the shore I look for teeth. At this beach, most of the teeth are black because of the chemical composition of the sediment offshore. At other beaches, fossilized teeth may be gray or brown or slightly green. Once you find the first tooth, youll know what color to seek. Of course, theres always a chance youll find a white shark tooth, but these are much harder to see against shells and sand. If youve never looked for shark teeth before, start out looking for black pointy objects. If the teeth are black, there will also be some black shell fragments that resemble shark teeth.  How do you know if its a shell or a tooth? Dry off your find and hold it up to the light. Even though a tooth could be millions of years old, it will still look glossy in the light. A shell, on the other hand, will show ripples from its growth and maybe some iridescence. Most shark teeth also maintain some of their structure. Look for a cutting edge along the edge of the blade (flat part) of the tooth, which may still have ridges. Thats a dead giveaway youve scored a shark tooth. A tooth may also have an intact root, which tends to be less shiny than the blade. Teeth come in a variety of shapes. Some are triangular, but others are needle-like. Good places to start are at the waterline, where the waves can help reveal the teeth, or by inspecting or sifting through a pile of shells.
