Living Thing Biology Essays - Nuclear Physics, Chemical Properties

Living Thing Biology Living things make up the world as we know it. Living things are involved in our life constantly, seeing that we are alive. There are five characteristics that are common to all living things. Living things are made up of one or more cells. Each cell is made up of living matter and is separated by a barrier that encloses the cell from its surroundings. However, there are many different kinds of cells that make up living things. A single cell can be one organism. These organisms are known as unicellular. Most of the organisms that we know best such as people, trees, and dogs are all made up of more than one cell. Organisms made of more than one cell are said to be multicellular. Another characteristic that living things share is that they reproduce. They reproduce, or make new organisms of the same sort. In order for a species to survive, it is a necessity for them to reproduce because all organisms die eventually. There are two ways living things reproduce, sexually and asexually. Sexual reproduction needs two cells from two different organisms to merge and form the first cell of a new organism. Asexual reproduction is when only one organism can reproduce without the assistance of another. The third characteristic of living things, is that all living things need to grow and develop. When an organism is growing, most go through a cycle called development. The single cell that starts the cell divides over and over again to make all the cells that the organism has when in adulthood. As the cycle continues the organism ages. Aging is when the organism becomes less efficient in the process of life. The organism will not be able to reproduce, and death comes as finally too. The fourth characteristic of a living thing is the ability to obtain and use energy. Living things obtain energy from their environment or their surroundings. All living things require energy to live and build their cells. This process is anabolism. Anabolism is the process in a living thing that involves putting together complex substances from simpler substances. Plants get their energy from the sunlight through a process called photosynthesis. Animals get their energy from food that is eaten. The food is then broken down through digestion, resulting in a release of energy called catabolism. Living things practice anabolism and catabolism through the whole time they are living. The balance of anabolism and catabolism is called metabolism. The fifth and final characteristic that all living things share is that all living things respond to their environment. Response to their environment can be sudden, through behavior, or gradual, in metabolic process or growth. Stimulus is anything in the environment that causes a living thing to react. Stimuli include light, temperature, odor, gravity, sound, water, and pressure. Plants generally act to stimuli slower than animals. The process in which living things respond to stimuli in ways to keep conditions in their body suitable for life is homeostasis. These five characteristics of living things are just the basics to knowing what makes up living things. Atomic Structure of Living Things The basic unit of matter is the atom. Atoms are extremely small, in fact, if you placed 100 million atoms in a row one after the other, it would be one centimeter long. Even though the atom is small it consists of even smaller particles, called subatomic particles. Scientists believe that there is at least 200 subatomic particles. The three main subatomic particles are the neutron, proton, and electron. In the middle of the atom there is a nucleus. The nucleus makes up 99.9 percent of the atoms weight even though it is a hundred times smaller than the atom itself. The nucleus contains two different kind of subatomic particles, the neutron and the proton. The proton has a positive charge and the neutron is a electrically neutral subatomic particle. Both are almost equal in mass, 1 amu (atomic mass unit). Another subatomic particle in the atom is the electron. It is negatively charged and it's mass is about 2000 times smaller than that of a neutron or electron. Usually the number or electron in an atom is the same as the number of protons. So, usually the atoms have not a positive nor negative charge, but they are neutral. Electron are not in the nucleus like the protons and neutrons are. They travel at very high speeds throughout the atom in energy levels. The energy levels are like orbits that surround the nucleus.

Fishers essays

Fishers essays The coniferous forests within Alaska, Canada and the United States are home to a blackish brown weasel looking creature. Its eastern range extends as far south as New York. In the western United States, it ranges as far south as the mountainous portions of central California and Utah. Fast on the ground and in trees, it is a wonder that this animal is not better known to us. This animal is named the fisher. No one really knows how this strange mammal got its name. It has a few names that it is called by, such as, Fisher Marten, Fisher Cat, Pennants Marten Cat, tha-cho (Big Marten), Black Cat, and Pekan. According to one story, the fisher got its name from the pioneers, who used fish to bait traps. The fish were being stolen by a dark-colored animal, which they named fisher. (Pringle, 2) The fisher is a member of the weasel family, Mustelidae, in the order Carnivore. It is classified as Martes pennanti. It has dark brown, glossy fur, which gets white tipped as the fisher gets older. The females hair is darker than the males. Some fishers have a frost cast around the head and shoulders, or a white patch of hair on the chest. They have long, slender, weasel like bodies. The adult fisher is usually 20 to 25 inches long, excluding their tail, which is about 18 inches long. It weighs between 3 to 15 pounds. It has strong muscular short legs, which are similar to those of weasels, mink, martens, and otters. They have bushy tails and strong claws that are retractable like a cats, allowing them to move about swiftly in the trees, which they make their homes in. Fishers are carnivorous, which means they eat meat. They hunt on the ground and in trees. Their main sources of food are snowshoe hares, birds, porcupine, mice, voles, shrews, moles, squirrels and other small mammals. In the spring and summer months, they also eat frog eggs, bird eggs, carrion, and fruits and berries. The f ...

Family Health Promotion Paper - Essay Example oted that the analyses of monoamine oxidase A gene - linked polymorphic region (MAOA – LPR) genotypes revealed that women who have been abused sexually in their childhood were more like to develop alcoholism and antisocial behavior. This study also revealed that those women with low activity variant are more likely to develop this problem compared to women with high activity variant (NIAAA, 2007). Abuse among the members in the family, assault, and homicide are some of the violent acts observed among alcoholic individuals (Casa Palmera, 2007). It was also reported that women and children alike are frequent abuse of alcohol – related problems (Casa Palmera, 2007). Casa Palmera (2007) noted that vandalism is an illegal act that is common among individuals under alcohol influence. Graffiti writing, public and private property destruction are among those acts of vandalism credited among alcoholics (Casa Palmera, 2007). A. Precontemplation Stage: During this stage, the client and his family deny of having a problem with alcoholism and want others to change their behavior instead, because they view others having the same problem. B. Contemplation Stage: During this time, the client and his family is acknowledging that he is having a serious problem with alcoholism and is taking into consideration obtaining treatment and rehabilitation. C. Decision and Determination: The client and his family are now thinking on how to avoid drinking alcohol and from getting hooked with it. During this time, he is beginning to think about his future being free from alcoholism. Educate the client and his family that alcohol produces mood and behavioral changes. Heavy and regular alcohol intake leads to liver cirrhosis, a leading cause of death secondary to chronic alcoholism (Kozier, et al., 2004). Kozier also noted that mixing drinking and driving causes crippling or fatal accidents. Social Learning Theory: This includes how the family, peers, and providers of the client help

RPM and a Core Component of Every Business Leader Research Paper

RPM and a Core Component of Every Business Leader - Research Paper Example Cooper (2010) says that any new approach or solution that is adapted to resolve a given issue must be evaluated in turn to assess its effectiveness and quality. In other words, it is simply not enough to propose a set of steps to tackle situations such as known surprises. In fact, there needs to be an established framework and a set of estimates that can help evaluate the responsiveness of the solutions devised and the extent to which they have helped in reducing the risks. The RPM method presents a number of approaches such as scenario planning, risk analysis, incentives and networks as a means to ferret out threats. However, it does not provide any subsequent methods or advise on measuring the success of these methods, thereby leaving open this question to contention among organizations that adopt any of these methods (Cooper, 2010). Lastly, many uncertainties are not restricted to a few specific factors and may sometimes influence through a number of frontiers. For example, Jack W elch, the former CEO of General Electric, was driven by psychological preconceptions in his bid for acquiring Honeywell. Watkins and Bazerman (2003) highlight that he completely ignored potential issues that could be encountered by European regulators. In this context, some researchers like Montier (2010) believe that Mr Welch’s decision may have been driven by factors beyond psychological and cognitive biases. For example, the internal organizational culture at General Electric could have been fragmented or distorted that may have resulted in the communication of inefficient and ill-constructed ideas to top-level management.

Crime Scene Documentation - Assignment Example In these cases, the accused is always acquitted as charges levelled against him/her cannot stand due to the malicious acts of the officers of destroying evidence that the court was to rely on. In the case State v. Blair 2013 Ohio 1270, the second district appellate court dismissed an indictment as a result of a law enforcement officer destroying a materially exculpatory video, which the defence was set to rely on in the case. The felony that was committed in this particular case was an assault, which was made on a law enforcement officer (Acker & Brody, 2013). There is a legal standard that is in place that bars the state from convicting the defendant in the following circumstances; if the state and in this case the prosecution together with case investigators fail to preserve â€Å"materially exculpatory evidence† or if the state acts in bad faith to destroy evidence that is potentially useful (Acker & Brody, 2013). In any scenario if the evidence involved is classified as materially exculpatory it is not the defendants duty proving that the state acted in bad faith to the court destroying the evidence however, the defendant only needs to prove to the court, it was the sole duty of the state to preserve that particular evidence despite destruction occurring either due to negligence or in bad faith (Gorelick & Solum, 2009). In so doing, the defendant has a duty to convince the court on the importance of the evidence to that particular case (Acker & Brody, 2013). This case involved a situation whereby a police officer tried to arrest a young man. The man in this case Blair tried to resist arrest as the officer had not fully explained to him the felony he had committed. The police officer decided to manhandle Blair by kicking him and choking him in order to arrest him successfully. Thus, in the process, there was a by-passer who was watching the whole incident and recorded it on his cell phone but noticing, the police

Factors Contributing To Building Defects

Factors Contributing To Building Defects Defects occur in building for a variety of reasons. This is perhaps not surprising when one considers the wide range of materials and techniques used in the construction of building, differences in condition on building sites and the varied occupational uses of the completed building. The defects in buildings occur because the inadequate or drawback of the original design, the building was constructed without according with the design or with appropriate practise, or the workmanship was below standard, or because the building has been accepted forces. The emergence of defects will affecting the comfort of occupants, such as noise interruption, solar gain and glare, have however been omitted as it is considered that they do not affect the fabric or the services and are not therefore building defects but purely defects of design. Basically, most of the defects are created from: The applications of forces either from internally or externally, even whole of building, or the components or materials of the building. The effects of materials no matter in a gaseous, liquid or solid state which contribute with the external climatic conditions and caused by the occupancy of the building The effects of biological agents Changes in temperature Those factors may lead to: Changes in the composition or condition of the materials used in the construction of the building such change may cause the materials more vulnerable to force Changes in the construction, ranging from slight cracking not affecting stability to complete destruction Changes in shape, size or weight Changes in appearance, including colour If slightly of changes from the original condition may not be considered as defects but this depends on the situation. As for major changes will generally be considered as defects, but may not if the changes do not affect the appearance. In general, Changes in composition can be result from: Fire The effects of gases, liquids and solids Biological agents Sunlight Changes in the structure from: Applied physical forces, including those from ground movements Fire Climatic condition Changes in shape, size and weight from: Applied physical forces Effects of gases, liquids and solids Effect of change of temperature Changes in appearance from: Wear Fire Effects of gases, liquids and solids Effect of changes of temperature Effect of sunlight From the more practical aspects, most of the defects can be placed in one of the three major groups and those defects are no means to clear-cut and will often overlapping. These groups are: Defects cause by dampness Defects cause by applied forces Defects cause by changes in size Besides, most of the defects can be occur due to the designer did not fully appreciate that the changes can befall in the construction or in the materials used, therefore the designer did not provided adequate safeguards in his design. If the chosen materials are unsuitable for the conditions, the materials will consider as defects. Most of the times, designer will take into account the cost to determine the choice of materials. It is important to understanding of the inherent properties of materials before select any materials. Before making the choices of materials for the construction, the designer must understand of the inherent properties of those materials. Greater use of the concept of trouble-shooting in advance can improved the designs and will undeniably lead to a reduction in the defects which occur in buildings. On the other hand, poor workmanship, especially do not compliance with the instruction given in the specification is also responsible for the occurrence of defects. The lack of maintenance or incorrect maintenance can reduce the effective life of a material and far lower than it should be achieved (Eldridge, 1976). Dampness Dampness is one of the defects which are most difficult to trace and diagnose. The dampness only can be perceived once it appears at the surface of the walls. There are countless ways in which water can exist in a building. Dampness may occur in the same building and at the same time even be responsible for the same damp patch. Buildings are assembled by a lot of different materials. All the materials have different inherent properties and many of them are water-absorbent. There are the major sources of water caused the dampness in building, such as construction water, intruding water, condensation and occupational (Eldridge, 1976). Construction Water In the construction of a building, a great quantity of water is required. A great quantity of water is required in the construction of a building, even for an ordinary building at least several tons of water is necessary. As well as some of the water will be used in setting the materials such as Portland cement, gypsum plasters and etc. Some construction water may be dried up at the time before the buildings have been occupied, but some construction water will still be retained in the buildings structure. Even though heating will dry up the water inside the structure, but in some case the water inside the structure are failed to dry up due to the walls have been applied the impervious decorations such as paintwork. And finally, the construction water will kept accumulate inside the walls (Eldridge, 1976). Intruding Water Rainfall is one of the reasons to allow the water into a building. While rain falls by gravity but it can be blown by the wind in all directions against a building. The driving rain will find any weakness on the wall and into a building either directly through the defects of the walls or indirectly by absorption. The water may transfer through the defects on the walls such as cracks or hollow sections for some distance and wet the internal surface of walls. Therefore, this would be very difficult to find the points of water entry. Besides, dampness may be enter a building from ground even the properly constructed of damp-proof course or membrane have been carry out. The watertightness of the joints is very important in the prevention of rain penetration. Intruding dampness which wets insulating materials may seriously lower their effectiveness and lead to condensation. The intruding dampness can be divided into penetration damp and rising damp (Eldridge, 1976). Penetration Damp Penetrating damp is caused by the porous nature of the building and as a result of external water getting into a building through the external walls and ultimately affects the internal wall surfaces. Besides that, the buildings near coastal areas or areas facing the sea can also suffer from penetrating damp. The penetrating damp of the walls will caused serious deteriorating affects to the internal finishing like damp staining, salting, blown plaster, spoiling and peeling of the wall finishes. Wall penetrating dampness occurs in a building are related with the somewhat faulty building work or the fault in the plumbing work which has allowed water to enter into the building. The common defects that can result in the transfer of water from the external faà §ade of a building into its living accommodation such as the defective of roof coverings, poorly maintained walls, poorly guttering and down pipes, poorly fitting or rotten door and windows frames, broken render or damaged pointing. Even these defects can be cured, but the affects of residual moisture within the building can continue to create problems for months and sometimes years. On the other hand, a watermark may be appearing on the internal wall and it will grow if the water continues to enter thus penetrating damp walls. In addition, the watermark will grow rapidly and become worse especially after the heavy rainfall. (David Sutcliffe, n.d.) A damp wall will take one month for each inch of the wall thickness to dry out after the source of the penetrating damp is removed. (David Sutcliffe, n.d.) Some of the buildings have exceptionally thick external walls and thus the affect of penetrating damp will continue over a longer period of time if nothing protective is done. The penetrating damp may be minimised, once the defect of the walls is correctly identified and the source of water ingress eliminated. Rising Damp Rising damp usually occurs in the older brickwork which the brickwork or the mortar between the brickwork is more porous. The mortar in the older buildings will losing its original adhesive properties, becomes soft and crumbles easily, almost reverting back to a sandy base, therefore the mortar will becomes absorbent and pass water through it. In other word, the rising damp is hardly occurs in the newer brickwork where the brick and cement mortar courses are in good condition. Besides that, the rising damp also may occur in the brickwork due to not providing the damp proof course or where the damp proof course has failed. The rising damp can be occur in the brick walls due to the water upward movement through the porous mortar from the ground salt (Chloride Nitrates), this action as known as Capillary Action. Once the rising moisture is above the floor level, the water evaporates and leaves the salt deposits behind. The evaporation often draws more water up and in turn leaves more salts behind. The longer the moisture is allowed to rise, the more salts will become evident. The rising damp will as a result of deteriorating affecting to the external finishes and internal finishes of the walls such as: Paint does not adhere to the wall. Wall paper lifts and stains appear on the walls. Plaster flakes away, feels soft and spongy, bubbles and white powder or crystals appear. Skirting boards and floor boards rot. Mortar frets and falls out between bricks and stonework. Stains or white powder appear on walls. There problems are mainly aesthetic problems only, however it is conceivable that the structural damage could result from extensive rising damp, and of course a damp mouldy environment could pose a health risk to people. (Graham Drage, Causes and Remedies for the Three Main Causes of Damp in Dwellings) Condensation Water vapour is normally present in the air. The quantity of water vapour contained depends on the temperature of the air. This ratio is called the relative humidity. Hot air is able to carry much more water vapour than cold air, so as the temperature of air increase, it is able to hole a greater volume of water vapour. Such water vapour comes from our breathing, bathing, cooking and other domestic activities. When the water vapour contact with cold surface it will converted into liquid water. The temperature of the surface at which the water vapours condensate is called the dew point. The condensed water may appear on any of the internal surfaces of the building or form within the construction and known as interstitial condensation. The condensed water may through a crack on the wall to appear possibly on the internal surface of wall even some distance from its points of origin. Therefore, this form of condensation can be very knotty due to the difficulty in identifying and its adve rse effect on the insulation. Besides, it also damaging and give rise to other defects to the walls such as the materials used in the walls especially in cavities and voids. Moreover, the condensation is most lightly to occur especially in locations where the relative humidity of the internal air is high such as bathrooms and kitchens. Some of the materials have the property of absorbing moisture from the air. The amount of water condenses in walls is very considerable indeed, because it is not only damage the fabric of a wall and lead to more frequent redecorating, but it is also may leading the wall to a state of almost permanent dampness and providing suitable conditions for the growth of mould and mildew. The growth of mould and mildew will affect the health of the buildings occupants. Occupational Besides the water vapour produced by the occupants of building (one adult produces half a litre of water in 9 hours simply from breathing), water may be present in a building by leaking pipes, tanks and cisterns. It will caused the problem of condensation become more worsen. Cracks Cracks are occurred because the building or part of building has been withstanding the applied forces greater than it can be withstand. These applied forces may have applied externally to the building, internally within the building or have been built up in the materials of the building as a result of chemical changes. These may be a single force or a combination of forces, or having a single cause or several causes. Much of the cracking occurs in the early in the life of the building is inevitable since it is due to the internal forces built up in many materials when the water used in the construction process dries out. Such cracking is generally superficial but it is potential to cause little problem later on if the remedial measure is not taking. Obviously every crack is a sign that the building is become instability. Some looked very serious cracks on the structural may have little or no effect on the stability either because the building has a high factor of safety or because the affected area does not influence to the stability of the structure. Rarely does a building collapse soon after the appearance of a crack, even if the crack is large. The cracking of the brick walls may be caused by overloading in structural, foundation settlement, excessive floor loadings, temperature settlement, contraction in structural members, or poor materials and poor workmanship in the original construction. The types of crack include horizontal cracks, vertical and diagonal cracks, shrinkage cracks and step cracks (Integrated Publishing, n.d.). Horizontal Cracks Horizontal cracks are generally long, wide cracks in the mortar joints that occur along the line of lintels over the window or along the line of the roof slab or floor. Where the horizontal movement cracks turn the corner of a building, they often rack down. Racked-down corner occur where the horizontal cracks along the side and end of a building meet. Normally, the horizontal crack not only continue around the corner but forms part of a diagonal crack that takes a downward direction and meet a similar crack from the other side, forming a V. The bricks inside this V are loosened and must be reset. Vertical and Diagonal Cracks Vertical and diagonal movement cracks usually occur near the ends or offsets of buildings. These cracks may also found extending from a window sill to the lintel or a door or window on a lower floor. The cracks can be from à ¢Ã¢â‚¬ ¦Ã¢â‚¬ º to à ¢Ã¢â‚¬ ¦Ã…“ of an inch in width and follow the mortar joints. However, in some cases, they may break through the bricks or other masonry. Shrinkage Cracks Shrinkage cracks are the fine hairline cracks that are found in mortar and concrete walls. the most noticeable ones are those running vertically, but a close examination of a section of a wall that leaks may also show them in the horizontal or bed joints of brick or block walls. Step cracks Step cracks is also known as stairstep cracks or stepping cracks, which is refer to cracks that follow the mortar joints in a brick o block wall. The cracks may be step up or step down along the wall. Generally, the step cracks is caused by minor movement of the footing, shrinkage or wall movement and by itself is not a major cause for concern. However, wide cracks or step cracks combined with other cracks and movement indicate a problem. Defect of External Finishes are various sorts of finishes was applied to the external faces of walls for a better achievement of the protection and aesthetically. Those finishes vary from rendering applied to structural walls to paint applied to walls. To carry out the finish-treatments to the wall may be subject to aspects such as defects intrinsic to the particular material, defects in the backgrounds to which they are applied and the defects arising from incompatibility of the finish and its background. Even though these various aspects are very important, but they are not considered fully enough to enable a correct diagnosis to be made. This is partly because the part played by the background is not appreciated. Generally it seems to be thought that if the background was in a satisfactory condition prior to the application of the finish any subsequent change in it must be due to the finish. On the other hand, the finishes also will be affected by the background. Wide cracks will present no difficulty since it may be possible to see into them, but if the cracks are only hair-crack width it will often be necessary to take a part of the finish off to expose the background. Sometimes the wrong type of finish has been used for the particular surfaces and condition and this possibility should be considered when deciding on the remedial work. It must also be considered at the design stage when buildings of similar type are to be erected in the same locality or where the exposure conditions are similar. Defect of Internal Finishes The internal finishes applied to the walls whether the sub-strate of such walls is an internal wall or the inner face of an external wall, the finishes are often identical and subject to the same occupancy conditions. For a variety of reasons the maintenance of the internal decorations is carried out at reasonably short intervals and this often conceals the consequential effects caused by the defects and therefore the symptoms of defects in the underlying fabric or in other related parts of a building. However, this may cause to take more time to discovery of a defect or camouflage its seriousness if the defects were found. Most of the defects concern either the plaster applied to the walls or the decorations. In addition the finishes such as timber paneling and decorative faced boards are unlikelihood to defects except the possible opening of the joints between the boards. Most of the cracks in the plasterboard will usually have their origin in the sub-strate. By inserting a thin and stiffish piece of wire in to the crack in the plaster can make sure whether the crack have it origin in the sub-strate and it is also a efficient way to measuring the distance penetrated of the crack. The decoration on the inner face of the external walls is likely to be damaged by the moisture. On the other word, moisture damage to the decoration on the partition walls is less probable because the surface of partitions will usually be warmer and therefore less vulnerable to condensation. If the ground salts (Chloride Nitrates) have accumulated in the wall over a long period and have been transferred into the plaster it will brought deteriorative effect for the finishes of the walls. This because the ground salts have the property of absorbing moisture from the air and influence the plasterwork damp. One of the problems with internal walls is ascertaining the form of construction and the materials used. If they are of solid construction it may often be possible to drill a small hole at some convenient point to find out what material has been used, but this information is accurate only if it can be assured that the same material has been used for the whole wall.

The Physics of Cross-Country Skiing :: physics sport sports cross country ski

Missing Figures Cross-country skiing is as much of a competitive sport, as it is a back country one. Cross-country skiing is enjoyed by people of all ages, and can be relatively inexpensive. There is no need for lift tickets and with a little maintenance equipment can last for decades. As a result of its broad audience, many people don't realize that physics plays a large role in cross-country skiing. This web page was designed to briefly describe some of the concepts behind the physics of skiing, and give a basic understanding of both the sport and the science. Friction is obviously an important factor of cross country skiing. On one hand, friction is necessary because without it a skier wouldn't be able to ski up hill or even move on flat surfaces. However, when racing, skiers prefer to have the smallest friction force working on them possible. In order to reduce the frictional forces which would slow them down, skiers wax the bottom of their skis. The types of wax which they apply to their skis have different functions. The hot wax which is applied to the entire ski reduces the friction between the ski and the snow. This allows the ski to glide on the snow and gives the skier more distance for each stride. Another type of wax is applied to the "kicker". The kicker is the area under the bindings. In other words the kicker is the area where most of the gravitational force of the skier is applied. Skiers apply a type of wax to the kicker that will cause the friction coefficient to increase. This allows skiers to be able to push off and ski uphill. In order to begin their outdoor adventure, a skier must first face the forces of static friction. Static friction is the force that keeps the skier at rest. As the skier overcomes the static friction there is a point where the coefficient of friction is greater than that of the kinetic friction that resists the skiers motion. It is clear to see this concept in the figure below. From the figure above, it is also easy to see that the kinetic friction remains almost constant for a range of speeds. This kinetic friction is the force which slows the skiers down after they start moving.

Assess the importance of the Celtic Iron Age regarding

The Iron Age was crucial as it was the development of highly sophisticated social and physiological development of humans'. There are multiple reasons why the Celtic Iron age has such significant. Firstly, the technology that had been created by the new found metal had major impacted on the Celtic society. Secondly, new lifestyles that massively change how humans use to live. Amongst this coinage had also been Introduced within Celtic regions which Invented more practical ways of trading. There was also an Increase interest In personal appearance along with a more relaxed lifestyle.Celtic people also began to Invent things to do for leisure. Lastly, Celtic religion started to evolve and politics was beginning to be invented. The Celtic Iron Age would be considered the most important within the Three-age System regarding to human societal development in Europe. It has made many improvements for humans to achieve the level of societal complexity today. The development of advance human society has mostly evolved though the revolutionary advances in weapons and crafts that were forged by Iron. Iron was very significant and made life for humans much easier after its discovery.Many of the weapons forged by iron was much stronger and lighter Han bronze, this allowed for improvements to be made to weapons and agricultural tools. Many of the common tools that were used during the Celtic Iron Age are till used today. For example the sickles or pruning hooks which were used by Iron Age farmers, the tool was used for cutting and shaping branches and hurdles unlike most farmers that use them today as to harvest cereal crops or cutting grass for hay. There were also several other tools that were developed during the Iron Age and its designs have been kept and improved on for many years.Tools such as the hammers, files, axes and many other metal-working tools. Even though early stages of these tools have already been developed during the Stone and Bronze Age, the Celtic Iron Age has truly perfect it. Evidence form everyday tools that society still uses in the 20th century shows many similarities and some can be considered virtually identical to the tools that were used more than two thousand years ago. The tools were made to build houses, make weapons and farm. These were the necessary tools to that develop human society Into a more complex one.Thus, this demonstrates that the Celtic Iron Age In Europe has help significantly to the development of human society s the discovery of Iron was revolutionary wealth humans. Without this ore, modern society In Europe would have not reach Its level of sophistication as Iron played a also shown impressive improvements that are still useful to everyday life in modern society. Therefore this shows how the Celtic Iron age has a high level of importance regarding to societal development in Europe. 1 Oliver, N. 2011. A History of Ancient Brittany.United Kingdom, Phoenix. Up. 217 2 Ibid. , 3 S. James and V. Rugby, †˜Iron Farming Tools', British Museum [weapon], (1997) http:// www. Brutishness. Org/explore/highlights/highlight_bob]sects/pee_BRB/I/ Ron_farming_tools. Asps Para. 3, accessed 27 June 2013. The importance of the Celtic Iron age regarding to human societal development in Europe was significant as the development and improvements of agriculture had greatly affected the way that people had lived in the in the past ages. It has also have shaped how humans tend to live today.The Stone Age and the Bronze Age had consisted of hunting and gathering food and there was little to no agricultural activity. However, the Celtic Iron Age was primarily agricultural and their daily routines would have consisted with maintaining crops and livestock. This can be seen though evidence in the environment. Evidence in forms of carbonized grains and pollen, it was shown that new crops were introduced and many wheat's had been farmed and grown in the fields. This meant that people began to develop permanen t settlement as they were preoccupied by farming and caring for livestock.As humans began to stay in permanent housing they also began to live in villages. This was unlike the previous ages as they were mostly hunter-gather societies when it was rarely done. They would only hunt in small groups and constantly travel as there were high risk of danger. The new agricultural life style opened many opportunities of improvement to the human society. Living in villages increase and improved human social development as they gain new skills through looking after life stock and farming as this improved their intelligence.As historian, a Neil Oliver quotes, ‘These steps alone had made a profound and deeply transforming social revolution's. The Iron Age did not Just improve human society by advancing in technology, however, they have also improved on having a better grasp on the practical necessities such social and leisure activities. During the Celtic Iron Age, the Celtic had much more time than their ancestors after the development of permanent housing. They were able to socialism more and focus on things that they were not able to in the past.This included on their personal appearances and activities for leisure. Archaeological evidence of Celtic Iron Age housing shows that many of these houses contained looms. Evidence of clothing form the Celtic Iron Age have shown to be made out of either linen or wool. The fabric would have been dyed bright colors and were woven with striped or checked patterns. There was also evidence from the archaeological record of brooches, pins and other dress accessories that would have played both a functional and decorative role on the clothing.Classical text also gives clues of what the Cells may have looked like an example of this is Odorous Sculls who was an Ancient Greek Historian, who wrote: When they are eating the moustache becomes entangled in the food, and when they that both men and women may have grown their hair long and also plaited it. This evidence has truly shown how human society had changed after the Iron Age. It demonstrates how humans have developed in intelligence by domesticating animals and also on how they have evolved.Thus, the importance of the Celtic Iron Age regarding to societal development is very significant as this had not only taught them a more relaxing way of life. It was also the first steps of humans being more social and advance creatures though their physiological development. Being able to maintain livestock, farm and also create accessories and tools that were much more developed than previous ages. 4 Jinni.

HTML accessed 6 July Lastly, the importance of the Celtic Iron age regarding to human societal development in Europe is significant as the religions and rules that existed during he time has truly effected on how society is run in the present. The Celtic Iron Age demonstrated that religion had a large impact in Celtic society much like it has in modern society. The Cells shared a common religious system, it also revealed that the Cells had strict rules of worship to their religion as evidence of human sacrifices such as the Tolland Man and Windy Girl have been found.The Greek and Roman texts provide a number of pertinent observations and a comprehensive account was given by Caesar in his description of Goulash society. Th e largest religion in modern society had also came out of the Celtic Iron Age. The Monastery of Illuminant Afar also known as the Illuminant Major can be considered the axis of early Celtic Christianity. Evidence of this includes the ruins of churches that are in modern Ireland and Britain. Many Celtic Scripps and illustrations have also suggest that Christianity has emerged from the era.This also wildly demonstrates how important the Celtic Iron Age is to the development of human society as without it, many things in modern society may not have existed. Political control and early stages of feudalism was also introduced as in each city state or village. In each village there would be an en or lord', legal or ‘king' and ins or ‘governor-priest' controlling it. This example demonstrates a high level of human intelligence and also an example of how the Iron Age was very significant regarding to humans societal development as this system last for centuries which demonstrate d its success.Another significant introduction was the introduction of coins within Europe. This demonstrated a large change in how humans were now living. Through coins, it was positive that trading had become a popular lifestyle, by having coins, the Cells were beginning to have an easier life style as they didn't need to trade in the crops that they grow. They were able to grow more food and grow wealthy. As this system of exchanging money for goods is still the impact it has on the development of human society, as from the Iron Age many new systems have developed.Which demonstrates how significant the Celtic Iron Age really is as many things may not exist if the Iron Age had not occur. Thus, the Celtic Iron Age was highly significant to human societal development in Europe. The Iron Age had introduced a number of complex things that enabled human intelligence to expand. This included farming, new tools, religion, politics and the adaptation of a new epistyle. The Celtic Iron Age had truly changed how humans have lived and improved.

Exponential Decay and Percent Change

Exponential Decay and Percent Change When an original amount is reduced by a consistent rate over a period of time, exponential decay is happening. Here is an explanation of how to work a consistent rate problem or calculate the decay factor. The key to understanding the decay factor is learning about percent change. Here’s an exponential decay function:    y a(1-b)x y: Final amount remaining after the decay over a period of timea: The original amountx: TimeThe decay factor is (1-b).The variable, b, is percent change in decimal form. Because this is an exponential decay factor, this article focuses on percent decrease. Three Ways to Find Percent Decrease The percent decrease is mentioned in the story.The percent decrease is expressed in a function.The percent decrease is hidden in a set of data. 1. The percent decrease is mentioned in the story. Example: The country of Greece is experiencing tremendous financial strain. They owe more money than they can repay. As a result, the Greek government is trying to reduce how much it spends. Imagine that an expert has told Greek leaders that they must cut spending by 20%. What is the percent decrease, b, of Greece’s spending?   20% What is the decay factor of Greece’s spending?Decay factor: (1 –b)   (1 - .20) (.80) 2. The percent decrease is expressed in a function. Example:   As Greece reduces its government spending, experts predict that the country’s debt will decline. Imagine if the country’s annual debt could be modeled by this function:   y 500(1-.30)x, where y is in billions of dollars, and x represents the number of years since 2009 What is the percent decrease, b, of Greece’s annual debt? 30% What is the decay factor of Greece’s annual debt?Decay factor: (1 –b) (1 - .30) .70 3. The percent decrease is hidden in a set of data. Example:   After Greece reduces government services and salaries, imagine that this data details the country’s projected annual debt. Greece’s Annual Debt 2009: $500 Billion2010: $475 Billion2011:   $451.25 Billion2012: $428.69 Billion How to Calculate Percent Decrease A. Pick 2 consecutive years to compare: 2009:   $500 Billion; 2010:   $475 Billion B. Use this formula: Percent decrease   (older– newer)/older: (500 Billion – 475 billion)/500 billion .05 or 5% C. Check for consistency. Pick 2 other consecutive years: 2011: $451.25 Billion; 2012: $428.69 Billion (451.25 – 428.69)/451.25 is approximately .05 or 5% Percent Decrease in Real Life: Politicians Balk at Salt Salt is the glitter of American  spice racks. Glitter transforms construction paper and crude drawings into cherished Mother’s Day cards; salt transforms otherwise bland foods into national favorites. The abundance of salt in potato chips, popcorn, and pot pie mesmerizes the taste buds. Unfortunately, too much flavor and bling can ruin a good thing. In the hands of heavy-handed adults, excess salt can lead to high blood pressure, heart attacks, and strokes. Recently, a lawmaker announced legislation that will force us in the land of the free and the brave to cut back on the salt that we crave. What if the salt reduction law passed, and we consumed less of the white stuff? Suppose that each year, restaurants will be mandated to decrease sodium levels by 2.5% annually, beginning in 2011. The predicted decline in heart attacks can be described by the following function:   y 10,000,000(1-.10)x , where y represents the annual number of heart attacks after x years. Apparently, the legislation will be worth its salt. Americans will be afflicted with fewer strokes. Here are my fictional projections for annual strokes in America: 2010: 7,000,000 strokes2011: 6,650,000 strokes2012: 6,317,500 strokes2013: 6,001,625 strokes (Note:  The numbers were made up to illustrate the math calculation! Please contact your local salt expert or cardiologist for real data.) Questions 1. What is the mandated percent decrease in salt consumption in restaurants? Answer: 2.5%Explanation:   Be careful, three different things   sodium levels, heart attacks, and strokes are predicted to decrease. Each year, restaurants will be mandated to decrease sodium levels by 2.5% annually, beginning in 2011. 2. What is the mandated decay factor for salt consumption in restaurants? Answer: .975Explanation: Decay factor: (1 -  b) (1-.025) .975 3. Based on predictions, what will be the percent decrease for annual heart attacks? Answer:   10%Explanation:   The predicted decline in heart attacks can be described by the following function:   y   10,000,000(1-.10)x  , where  y  represents the annual number of heart attacks after  x  years. 4. Based on predictions, what will be the decay factor for annual heart attacks? Answer: 0.90Explanation: Decay factor: (1 -  b) (1 - 0.10) 0.90 5. Based on these fictional projections, what will be the percent decrease for strokes in America? Answer:   5%Explanation: A. Choose data for 2 consecutive years:   2010: 7,000,000 strokes; 2011: 6,650,000 strokes B. Use this formula:   Percent decrease (older – newer)  / older (7,000,000 – 6,650,000)/7,000,000 .05 or 5% C. Check for consistency and choose data for another set of consecutive years: 2012: 6,317,500 strokes; 2013: 6,001,625 strokes Percent decrease   (older – newer)  / older (6,317,500 – 6,001,625)/6,001,625 approximately .05 or 5% 6. Based on these fictional projections, what will be the decay factor for strokes in the America? Answer: 0.95Explanation: Decay factor: (1 -  b) (1  - 0.05) 0.95 Edited by Anne Marie Helmenstine, Ph.D.

Equus Essay Example

Equus Essay Example Equus Essay Equus Essay Essay Topic: Equus Equus Dysart Analysis In his telling of a dream he had, Dysart describes an unusual ritual in which he is responsible for killing young boys and girls and removing their organs so that his assistant priests can analyze them. With amazing surgical skill, Dysart manages to cut up child after child, feeling sicker with each one. However, he tries not to make his nausea flagrant to the other priests, for he fears that he will be next to be sacrificed if he is exposed. While trying to maintain a professional and apathetic appearance, he feels his mask, which was covering his sickened face, slip to reveal his â€Å"green sweat,† a sign of weakness. As a result, the priests tear the knife out of his hand, causing him to wake up. When a person dreams, all of his or her subconscious fears or pains are allowed out. However, since the actual pain or fear may be too intense for the person to handle, the mind uses symbols to create a dream through which all of the pain and fear is released. In this case, it appears that Dysart has the constant underlying fear of being seen as weak or a fraud by either his patients or his colleagues (the priests). He is afraid that every move he makes is being watched and that his â€Å"mask,† or reputation, will not be able to protect him. He sees himself as a very confident and strong person when behind this â€Å"mask,† but deep down he has problems of his own that will be seen as weak. From the above statement, it could be deduced that while he tries to help others and show security in tough times, he is actually very insecure at a deeper level and has the constant fear of this insecurity being exposed. The sacrifice itself symbolizes the main theme that he hates his job in which he peels away layers of children’s minds using psychoanalysis, or his â€Å"knife. † By peeling away layers of the children, he is, in a sense, taking away their uniqueness and making them all the same, hence his wording: â€Å"a herd of children,† symbolizing a herd of sheep, which are all the same. His sickness and nausea in his dream is symbolic of the guilt he feels from cutting open children psychologically, just as he is trying to do to Allen. The diction especially emphasizes his hatred and guilt for his job, using the word â€Å"red,† symbolizing blood, to describe the soil. Thus far, he has only begun to peel away the layers behind Allen’s obsession with horses. As the text goes on, more and more is revealed until a complete picture is created.

Strategic Management - Essay Example Innovation is an important tool for businesses that is born out of some factors such as globalization and outsourcing as these two tend to push the need for an organisation to become more effective and efficient in their operations. In essence, organisations require innovative processes in order for them to cut down on production costs while making sure that they deliver quality products that would make them to be distinguished within the market they operate in. According to Kelloir (2007, p. 180), one factor that drives innovation for a business is the expectations that consumers have because they are known to yearn for products that can help make life easy for them. An example of this would be the need for consumers to bank conveniently without having to go physically to the bank, which facilitated the e-banking options that makes them to access their money at the click of a mouse button through the internet. With this, customers will go for service providers that provide these ser vices despite the cost implications that this service might attract because they are willing to spend more in order for them to be satisfied. One fact that product and service producers understand is that consumers cannot settle for less if they know that they can go somewhere else and find what they want making innovation and being entrepreneurial to be part of their firm’s. When it comes to the various approaches to innovation for entrepreneurs, Garner (2009, n.p) asserts that they understand that this aspect is what makes them unique within their markets by making it to be a priority. For one, some entrepreneurs can view innovation from a strategic point view by asserting that this can hold the future success of their organisations. However, some entrepreneurs when asked say that they find it hard to integrate innovation to be part of the strategic priorities that they have because of the cost

Software Piracy Assignment Example | Topics and Well Written Essays - 1750 words

Software Piracy - Assignment Example hical means 4: Government Government must provide the autonomy to each stakeholder about the use of software for their interests Government must ensure that pirated software does not harm the interests of the original creator as well as other stakeholders It is the duty of government to tell the truth about software piracy The Dilemma (Software Piracy) Software consists of programs that are designed to perform specific tasks for the different classes of users. Today, software applications are widely being used by individuals, government and business organizations for a variety of purposes. The software programs’ utilities are numerous in certain areas such as hospitals, banking education and space studies. Software programs can be purchased from software vendors. Eventually, certain general purpose software programs are available on internet, as freeware and shareware. However, the freeware and shareware software do not have much capabilities that are owned by the retail softw are packages (University of West Florida, 2012). Software piracy can be defined as the illegal copying, distribution or in general the illegal use of software. In other words, software piracy can be described as copying of software programs by individuals or business organizations either with profit motive or to harm others. The advancement in technological systems and tools has not only a favorable impact on the society but has also contributed immensely towards software piracy throughout the globe. Software piracy has serious impacts both on national economy as well as on the software producing organizations. The software producing companies spend millions of Dollars on their research activities for inventing particular software. Unfortunately, a few individuals and organizations take negative advantage of the technological advancements bothering less about the nation’s economy and software producing organizations which results in the form of pirated software (Ohio Literacy Resource Centre, 2001). Consequently, such factors have attracted the interests of many researchers to choose software piracy as one of the largely debated ethical issues. Three Principles The three principles selected for the matrix include Autonomy, Non-maleficence and Veracity. Autonomy can be described as freedom of an individual to take his/her own decisions. Every individual is free to use genuine or pirated software which is solely based on the conscience of an individual to consider it as ethical or unethical. However, the decision an individual takes should not harm any other individual or group or it should be non-maleficence. At the same time, the decision should not violate the rules and the laws established by the state or federal government. The truth related to incurrence of any act in relation to software piracy should be brought into limelight so that any such occurrence of piracy in future can be prevented. It can also benefit to create awareness about software pi racy and the harm that it can create to the
