Strength And Conditioning Programme Physical Education Essay

Quality And Conditioning Program Physical Education Essay Quality and Conditioning is the mix of obstruction preparing and continuance molding that is utilized by competitors and sports groups to improve and help their presentation (Driskell, 1999). Game explicit wellness can incorporate an organized dynamic program that could contain power, strong perseverance, quality, speed, vigorous or anaerobic molding (Steindler, 1955). It has been demonstrated that quality and molding programs increment sports execution, creating better athletic outcomes and diminishing the occurrence of injury (Burrows, 2007). Quality and molding programs are reasonable for competitors performing at recreational levels, world class levels, sports groups or any other individual hoping to discover new preparing strategies that may raise their presentation abilities (Baechle Earle, 2000). The point of this task is to attempt a necessities investigation for a picked game and position and to structure and layout a multi week preparing program reasonable for the individual competitor. The task will consider periodization just as an examination of the macrocycle, mesocycle and microcycle areas of a preparation program. The game and position that will be examined inside this report is football and a focal safeguard. Football is a requesting sports as far as the exertion the players need to place into the game. Football preparing and molding is basic. Players can cover around 8-12km during a match of which 24% is secured by strolling, 36% secured by running, 20% flowing, 11% running, 7% moving in reverse and 2% moving while possessing the ball (Reilly, 1996). Focal protectors need a wide scope of properties, which incorporate stature, Strength, balance and a decent mindset. Saif (2002) guaranteed that a protector needs to have great fixation during games and furthermore require expertise properties, for example, handling and heading. Football players need to have magnificent perseverance. They require a VO2max that has been accounted for to run somewhere in the range of 55 and 70 ml/kg/min in tip top entertainers (Bangsbo, 1991). The game is played around 80-90% of greatest pulse (Helgerud et al, 2001). The more prominent a players high-impact limit, the more noteworthy the separation they would cover during a regular game (Reilly Thomas, 1976). Numerous elements should be considered to plan and execute a fruitful preparing program. These elements incorporate periodization, macrocycle, mesocycle and microcycle alongside other fundamental stages. These are for the most part factors that should be considered all together for an effective preparing program. Periodization is an arranged execution of specific preparing stages (Bompa Haff, 1996). The preparation during the periodization stage depends on expanding and diminishing the volume of redundancies, time and measure of sets. What's more an expansion and lessening in power. These measures are executed when arranging an organized preparing program. A significant quality of periodization preparing is the booking of a recuperation period. The chief qualities of periodization incorporate inventiveness, strategic planning and usage of the recuperation (Bompa, 2005). Instances of periodization programs incorporate, Stepwise where preparing incorporates high volume with low power and advances to low volume and high force. Moreover, Undulating periodization is utilized. This is the place volume and force of preparing are changed over the span of a brief timeframe. Periodization is the best type of preparing when expecting to enhance muscle quality, engine execution and body creation. The macrocycle can be characterized by four unique parts. These segments incorporate the quantity of rivalries, dates of rivalries, the recuperation time frame among rivalries and the arrangement time frame before rivalry. (Dick, 2002) The microcycle is the littlest piece of the general program as it represents just a single seven day stretch of the preparation. The mesocycle is the piece of the year that the competitor is in, for instance mesocycle 1 will be the pre-season stage. The macrocycle is the general program based longer than a year (Dick, 2002). The Anatomical Adaptation is built up toward the beginning of the period or following the change stage. It is presented before the season begins as it adjusts the body for future quality projects. The point of this stage is to include the entirety of the muscle bunches which plan muscle, tendons, and ligaments and participates in anticipation of preparing. These quality projects should hope to incorporate all pieces of the body, for example, arms and legs yet additionally for the center region, which incorporates the lower back, mid-region and spinal section musculature. The muscle zones present help for the arms and legs, to help retain any stun during practices that require landing or falling. This period is basic since it creates target development of the muscles. Most extreme quality stage sets to build up the most noteworthy power conceivable. The preparation requires the competitor to prepare at 85-100 percent of 1RM. Numerous games require power, solid continuance or a blend of both. This stage will last somewhere in the range of 1 and 3 months relying upon the competitors needs (Bompa, 2005) The change stage changes the most extreme quality that has been created prepared to use during serious. This change happens when explicit preparing is performed. All through this stage a guaranteed degree of most extreme quality must be obtained in any case force will break down. Weight preparing is the most suitable strategy for doing this. The span of this period relies upon the capacity being changed over. The standard time frame is somewhere in the range of 4 and 5 weeks. Transformation to solid perseverance is 6 two months because of anatomical changes that take more time to change (Bompa, 2005). The opposition eliminate comprises of work conveyed during pre-season and should be kept up to diminish the likelihood of detraining. On the off chance that a competitor doesn't keep up their pre season preparing, at that point muscle strands can diminish, power is lost as there is a lessening in engine enlistment and speed which can bring about a reduction of intensity. These abatements can bring about horrible showing during the season. A change period is regularly known as the slow time of year. The point of this stage is to expel any exhaustion a player has created. It is a strategy for recharging the vitality frameworks by diminishing the volume of activity. This can likewise be a viable method of lessening the mental burdens that the player could understanding during preparing and rivalry. This unwinding period can permit the player to slacken up and rest. Despite the fact that this period has benefits it should last no longer than 4 a month and a half as there would be incredible decay of the players preparing. (Bompa, 2005). Preparing projects can be created to help the advancement of the player.The objective set to accomplish in the preparation program is to attempt to improve execution levels. This incorporates wellness and expertise levels. To discover the enhancements of a player the estimations will be recorded through wellness testing as a marker to recognize if certain segment abilities are improving or not (Fleck and Kraemer, 2004). When arranging a preparation program for a specific game, Specificity must be thought of. This partners to how much contrast there is among preparing and execution. This is significant, as preparing improperly could eventually negatively affect execution. Execution levels are estimated through wellness testing. The levels will be surveyed before the preparation program and after the preparation program to check whether, there has been any improvement. Then again, the program may give indications of an abatement in aptitude levels on the grounds that the preparation program didn't work and along these lines changes should happen to tackle the issues promptly (Brooks, 2004). When structuring a quality and molding program the experience of the player must be considered. This is on the grounds that it is simpler to improve a player at a lower level, for example, novice association or Sunday group than a player who is at proficient level (Reynolds, 1982). This is on the grounds that; to improve an expert player different components must be considered, for example, the demeanor of the payer. On the off chance that the players mentality to improve is acceptable, at that point it will get simpler to improve than if the player has an awful disposition towards it anyway this could likewise be a factor for beginner players (Magnusen and Rhea, 2009). Quality and molding programs must consider the season, for example, in the event that it is Pre season or in season and so on. Grouchy (2007) recommends The 4 Phases of a football quality preparing program which incorporates, slow time of year, Off-Season/Early Pre-Season, Late Pre-Season and In-season. During the slow time of year players should hope to fabricate utilitarian quality. Football like any game, puts a ton of interest on the body. Most players kick the ball with a predominat foot and utilizing a similar engine designs, a few muscles grow more than others. A few joints are additionally experience more worry than others. The objectives of this stage are to set up the joints, muscles, tendons and ligaments for increasingly exceptional work in resulting stages. With a decent establishment to expand on after stage one the player is set up to move into stage 2 which is the slow time of year/early pre-season period where they set to fabricate maximal quality. The objective of this stage is to build up the most elevated power conceivable. Since power is our general result, it bodes well to create quality first and afterward convert it into football explicit force. The point is to finished this stage before the beginning of the period. That way the last phases of pre-season preparing can concentrate on force and quality intense exercise. Stage three is the late pre-season solid force and quality continuance. In this period of football quality preparing, objective is to change over your quality increases into soccer-explicit force and strong continuance. Football is one of only a handful hardly any games requests ro

Book Review Essential Words for the TOEFL (Barrons)

Book Review Essential Words for the TOEFL (Barrons) My grade for Essential Words for the TOEFL: B+. Note, however, that I have the 4th edition, from 2007. This book has now reached its 7th edition. I have no idea what has changed. Barrons doesnt usually change much from edition to edition, so I suspect the new edition is pretty similar.Im going to keep this review quite short, since you can read my feelings about vocabulary books over in my review of TOEFL Power Vocab from Princeton Review. Basically, though, I dont want students to focus too much on vocabulary in the speaking and writing sections, but I recognize that studying vocabulary can help them in the listening and reading sections. Especially the latter section.Barrons vocabulary book is similar to Princeton Reviews book. It is mostly just lists of words and definitions. In this case they are divided into 30 lessons of about 15 words each. The words selected for each lesson dont seem to be based on similar themes or structures.While Princeton Reviews book includes a short qui z every few pages, Barrons includes ten actual TOEFL reading question (vocabulary type, of course) at the end of each lesson. I cant really say if the questions are accurate, but I dont think that is the point. They mainly serve to help students understand the meaning and usage of each word. And, yeah, I guess they help students understand what a vocabulary question looks like and how it is put together.The words here seem a bit more difficult that in Princeton Reviews book thankfully. Some of them are still too easy, though.Heres page 69: forbid, petition, relinquish, resilient, tempt.Heres page 229: maintain, mediocre, negligible, parallel, peculiar, potentHeres page 277: forfeit, precarious, severe, sporadic, superior, wantonI guess teachers should glance at the book to see if the overall level is suitable for their students. I would probably recommend it for students scoring 90 and below.

The Crucible By William Shakespeare - 1468 Words

No matter how brave or heroic a person is in his or her society, there is always something that surfaces that people would consider a character flaw. In the play The Crucible there are some truly heroic characters who deserve to be admired, and there are other characters who are filled with hubris and an overinflated sense of themselves. Some characters, such as Reverend Parris, care too much about their reputation, and this egotistic attitude can become the cause of their downfall. Others, like John Proctor, are not willing to live anymore because their reputation has been spoiled. And some characters, such as Abigail Williams, are so self-important that they believe they have the right to love and be with anyone, even if that person belongs to someone else. Having excessive pride about their positions in the society, killing themselves just because their reputations have been tainted, or believing that they are entitled to be with anyone of their choosing regardless of the circums tances are the situations various characters in The Crucible find themselves in. These characters believes that they must hold onto their reputations at all cost †¦ Reverend Parris, a very wealthy man in the society is filled with a spate of pride.

Nuclear Energy Social Benefits and Costs Free Essays

Its impacts on the environment are almost Non-existent if well managed: It occupies only small surfaces of land and consumes small amounts of fuel; its waste is small, confined, and isolated from the environment. there is no industry in the world that can present the same excellent record of safety performance as the nuclear industry. Introduction to Nuclear Energy for Civilian Purposes * Most early atomic research focused on developing an effective weapon for use in World War II. We will write a custom essay sample on Nuclear Energy Social Benefits and Costs or any similar topic only for you Order Now After the war, the United States government encouraged the development of nuclear energy for peaceful civilian purposes while continuing to develop, test, and deploy new nuclear weapons. * The Experimental Breeder Reactor I at a site in Idaho generated the first electricity from nuclear energy on December 20, 1951. * As of 2008, 13% of the world’s electricity comes from nuclear energy. Fewer than 400 nuclear power reactors were operating as of May 2012 (Japan’s 54 reactors were gradually taken offline after the March 2011 meltdowns at Fukushima Daiichi). There were also 60 nuclear reactors under construction. * In the United States alone, there are 103 nuclear power reactors, which provide about 19% of the nation’s electricity. * A new nuclear power plant has not been ordered in the U. S. since 1973. How It Works – The Scientific Process Behind Nuclear Energy * Nuclear energy relies on the fact that some elements can be split (in a process called fission) and will release part of their energy as heat. Because it fissions easily, Uranium-235 (U-235) is one of the elements most commonly used to produce nuclear energy. It is generally used in a mixture with Uranium-238, and produces Plutonium-239 (Pu-239) as waste in the process. * A nuclear power plant generates electricity like any other steam-electric power plant. Water is heated, and steam from the boiling water turns turbines and generates electricity. * The main difference in the various types of steam-electric plants is the heat source. Coal, oil, or gas is burned in other power plants to heat the water. Heat from a chain reaction of fissioning Uranium-235 boils the water in a nuclear power plant. Some have compared this process to using a canon to kill a fly. * On March 11, 2011, a strong earthquake hit off the coast of Japan. The resulting tsunami caused meltdowns at multiple reactors at the Fukushima Daiichi nuclear power plant. For more information on the accident at Fukushima,  click here. * On April 26, 1986, the No. 4 reactor at the Chernobyl power plant (in the former U. S. S. R. , present-day Ukraine) exploded, causing the worst nuclear accident ever. SOCIAL COSTS External Costs * The waste material generated by nuclear energy from nuclear fleets to nuclear plants is radio-active, and for this waste to naturally decompose it takes from hundred thousand to millions of years, if it is not fully decomposed it still poses a threat. * The waste material created by nuclear energy if it isn’t disposed well, and terrorists can have access to it the result would be disastrous, as it can be used for nuclear weapons. If there is any nuclear accident the reaction would spread to a large area and apart from destroying people’s lives it would also cause other people and different organisms to be radio-actively exposed creating long-term health problems. * Nuclear accidents tend to destroy the natural ecosystem, by polluting water-bodies and animals. * Nuclear accidents can cause climate change: extreme heat waves or droughts. Private Costs * Allocat ing the resources (land) for building the nuclear energy power plant is very difficult, as finding a fairly sparsely populated region close to a water-body isn’t available readily. The investment needed for to build a nuclear energy power plant, and the capital for its safety measures all costs a lot of money(in billions). * If a nuclear power station wants to shut down, the process of nuclear decommissioning (process of entrusting the land for other uses) is also very expensive. * The process of getting rid of the nuclear waste is very costly, as the investors need to hire highly skilled people to enclose this waste into tin boxes for it to degrade, and the capital (equipment) and transportation facility for this process is very expensive. Nuclear accidents can three times more than the operating revenue of that nuclear power plant. SOCIAL BENEFITS External Benefits * Nuclear energy has very high chances for development, as some can produce less nuclear waste, others have ch ances of efficiently reproduce the waste, and nuclear power plants can run on other types of radio-active materials, or with little waste products producing huge amount of electricity. * Nuclear energy running on different types of radio-active material is predicted to fulfil the increasing demand for electricity for more than 3000 years. Nuclear energy is the one of the energy type which does not release any greenhouse gases into the atmosphere, but only releases water-vapour as a by-product, but yet still has the capacity to produce a lot of energy. * The waste product generated from fossil fuel is far greater than nuclear energy, the burning of coal not only produces greenhouse gases but also fairly radio-active materials which are leashed into the environment, but in nuclear energy the radio-active waste is shielded from the environment and is far less compared to that of burning fossil fuels. Nuclear energy plants have the ability to produce large amounts of electricity which w ould not only be cheap but would have a high voltage; this would help a country’s industrial (secondary) sector. Private Benefits * The amount spent on buying fuel (uranium rods, etc. ) is very less. * For investors according to their scale of preference to develop a power station, a nuclear energy plant would be high on the scale. Because the chances of there being a nuclear accident is very low, as there is no power industry in the world that can present the same excellent records of safety measurements than the nuclear energy industry. Despite the Chernobyl disaster which was because of the USSR developing very fast and lack of the type of technology available today, and the Fukushima nuclear disaster being an act of God, which the world wasn’t prepared for but now is.

This paper explains that although Western culture recognizes only two sexes, other sexes exist as well. This paper examines the possibilities of more than two sexes from a biological and sociological viewpoint. The paper points out the problems faced by those who do not fit into the two sex definition. The definition of intersexuality sets a basis to be able to group Sterlings five sexes into their own subgroups. The standard medical definition of intersexuality or intersex refers to the three major subgroups with some mixture of male and female characteristics, which include: the herms, ferms, and merms. The hermaphrodites or herms, posses one testis and one ovary, the productive gonads. In some cases, with the true hermaphrodites, the testis and ovary grow separately but bilaterally. In other people, they grow together within the same organ, forming an ovo-testis.

50 Million Years of Whale Evolution

50 Million Years of Whale Evolution The basic theme of whale evolution is the development of large animals from much smaller ancestorsand nowhere is this more evident than in the case of multi-ton sperm and gray whales, whose ultimate forebears were small, dog-sized prehistoric mammals that prowled the riverbeds of central Asia 50 million years ago. Perhaps more intriguingly, whales are also a case study in the gradual evolution of mammals from fully terrestrial to fully marine lifestyles, with corresponding adaptations (elongated bodies, webbed feet, blowholes, etc.) at various key intervals along the way. Until the turn of the 21st century, the ultimate origin of whales was shrouded in mystery, with scarce remains of early species. That all changed with the discovery of a huge trove of fossils in central Asia (specifically, the country of Pakistan), some of which are still being analyzed and described. These fossils, which date from only 15 to 20 million years after the demise of the dinosaurs 65 million years ago, prove that the ultimate ancestors of whales were closely related to artiodactyls, the even-toed, hooved mammals represented today by pigs and sheep. The First Whales - Pakicetus, Ambulocetus, and Rodhocetus In most ways, Pakicetus (Greek for Pakistan whale) was indistinguishable from other small mammals of the early Eocene epoch: about 50 pounds or so, with long, dog-like legs, a long tail, and a narrow snout. Crucially, though, the anatomy of this mammals inner ears closely matches that of modern whales, the main diagnostic feature that places Pakicetus at the root of whale evolution. One of Pakicetus closest relatives was Indohyus (Indian pig), an ancient artiodactyl with some intriguing marine adaptations, such as a thick, hippopotamus-like hide. Ambulocetus, aka the walking whale, flourished a few million years after Pakicetus and already displayed some distinctly whale-like characteristics. Whereas Pakicetus led a mostly terrestrial lifestyle, occasionally dipping into lakes or rivers to find food, Ambulocetus possessed a long, slender, otter-like body, with webbed, padded feet and a narrow, crocodile-like snout. Ambulocetus was much bigger than Pakicetusabout 10 feet long and 500 pounds, much closer to a blue whale than a guppyand probably spent a significant amount of time in the water. Named after the region of Pakistan where its bones were discovered, Rodhocetus shows even more striking adaptations to an aquatic lifestyle. This prehistoric whale was genuinely amphibious, crawling up onto dry land only to forage for food and (possibly) give birth. In evolutionary terms, though, the most telling feature of Rodhocetus was the structure of its hip bones, which werent fused to its backbone and thus provided it greater flexibility when swimming. The Next Whales - Protocetus, Maiacetus, and Zygorhiza The remains of Rodhocetus and its predecessors have been found mostly in central Asia, but the larger prehistoric whales of the late Eocene epoch (which were able to swim faster and farther) have been unearthed in more diverse locations. The deceptively named Protocetus (it wasnt really the first whale) had a long, seal-like body, powerful legs for propelling itself through the water, and nostrils that had already begun to migrate halfway up it foreheada development foreshadowing the blowholes of modern whales. Protocetus shared one important characteristic with two roughly contemporary prehistoric whales, Maiacetus, and Zygorhiza. The front limbs of Zygorhiza were hinged at the elbows, a strong clue that it crawled onto land to give birth, and a specimen of Maiacetus (meaning good mother whale) has been found with a fossilized embryo inside, positioned in the birth canal for terrestrial delivery. Clearly, the prehistoric whales of the Eocene epoch had a lot in common with modern giant tortoises! The Giant Prehistoric Whales By about 35 million years ago, some prehistoric whales had attained gigantic sizes, bigger even than modern blue or sperm whales. The largest genus yet known is Basilosaurus, the bones of which (discovered in the mid-19th century) were once thought to belong to a dinosaurhence its deceptive name, meaning king lizard. Despite its 100-ton size, Basilosaurus possessed a relatively small brain and didnt use echolocation when swimming. Even more important from an evolutionary perspective, Basilosaurus led a fully aquatic lifestyle, birthing as well as swimming and feeding in the ocean. Contemporaries of Basilosaurus were much less fearsome, perhaps because there was only room for one giant mammalian predator in the undersea food chain. Dorudon was once thought to be a baby Basilosaurus; only later was it realized that this small whale (only about 16 feet long and half a ton) merited its own genus. And the much later Aetiocetus (which lived about 25 million years ago), though it weighed only a few tons, shows the first primitive adaptation to plankton feedingsmall plates of baleen alongside its ordinary teeth. No discussion of prehistoric whales would be complete without a mention of a fairly new genus, the aptly named Leviathan, which was announced to the world in the summer of 2010. This 50-foot-long sperm whale weighed only about 25 tons, but it seems to have preyed on its fellow whales along with prehistoric fish and squids, and it may have been preyed on in turn by the largest prehistoric shark of all time, the Basilosaurus-sized Megalodon.

Signs youre stuck in the rat race

Signs youre stuck in the rat race We’ve all heard the phrase rat race before- it refers to a seemingly never-ending, pointless, and even self-defeating pursuit, and it’s often used when referring to one’s job or career. Individuals who are stuck in the rat race are unhappily going through the motions in life, trudging through the daily grind of their workday feeling unfulfilled, unchallenged, and uninspired until they go home at the end of the day- only to repeat the whole process again. Individuals who are stuck in the rat race are more than just unhappy- they’re actually negatively affecting their health and well-being. According to a recent Forbes article, individuals who hate their jobs face some serious consequences, including increased risks for stress, sleeplessness, illness, and mental health issues. An article by The Atlantic  even goes on to suggest that workplace unhappiness can shorten your lifespan!Obviously, individuals who are stuck in this unfortunate situation have every good reason to try and get out of it. Are you one of them? The truth is, sometimes people get so busy and wrapped up in the responsibilities and activities they have going on in their daily lives that they fail to take stock of their current situations. You may very well be stuck in the rat race and not even know it!Use the following signs to determine if you need to make some changes to your daily life.1. Your energy and enthusiasm levels are low.Are you like the energizer bunny when you get up in the morning? Do you go through an average workday full of â€Å"get up and go† enthusiasm for what lies ahead? Or maybe you’re more like a wilted flower or droopy basset hound who practically needs to be dragged through the day, and can’t wait to get back home so you can†¦lie around and do absolutely nothing. We all have good days and bad, but if more often than not you’re facing each day with a real lack of energy and enthusiasm, that’s a good sig n your stuck in a rat race and may need a change.2. You’re stuck in the past.Do you spend more time thinking about â€Å"past glories† than future opportunities? Do you gladly reminisce about days gone by and what you have done at the expense of what lies ahead and what you will accomplish? Individuals who are stuck in the rat race avoid thinking about the present and the future as a protective mechanism- keeping them from having to confront an unhappy reality or an uncertain tomorrow. If this sounds like you, you might just be stuck in a rut.3. You lack purpose.Folks who are in happy places in their lives are fueled by a sense of purpose and gamely tackle each day, along with the challenges and goals they’ve set for themselves. Those stuck in less fulfilling situations? Not so much. And it’s not hard to imagine the vicious spiral this creates, leading you to accomplish less and less as the days drag on. Don’t get stuck in a rat race spiral!4. Youà ¢â‚¬â„¢re noticing changes in your health and wellness.We’ve already touched on this one- when you’re stuck in the grinding gears of the rat race you’re going to experience a negative effect on your health and well-being. The ravages of stress, tension, sleeplessness, anxiety, and more will begin to gnaw away at you- and you’ll notice it. Tack on to this that people stuck in the rat race often make poor diet and exercise choices and it’s easy to see that this is a road to ruin.5. You feel powerless to effect change or think there’s nothing better out there for you.One of the real tragedies of being stuck in the rat race- as if we haven’t mentioned enough of them already- is that it robs you of the very ability to see a way out of it. It’s common for those stuck in a rut to feel that there’s simply no way out or have such a negative raincloud following them that they can’t even fathom that there’s something better out there. It’s not a good place to be.If after reading this you’ve realized that you’re stuck in the rat race and are starting to worry or panic- take a deep breath. It’s always better to know the truth and it’s never too late or a bad time to figure out where you are with your job situation- good or bad- and make a change!

On lapham's paper FIGURES OF SPEECH - Essay Example Some of these structures are extremely itemized, making inquiries that oblige data from once in a while got to memory banks. Why does a specialist pose these questions? The specialist is attempting to build a precise picture of your state of wellbeing. Your wellbeing is intensely affected by the past. Your heredity, past practices, past encounters is exceptionally paramount determinants and pieces of information to your current condition. At whatever point you come back to the specialist, he or she hauls out a record which holds all the notes from past visits. This record is a history of your wellbeing. Lapham see plainly that the past matters because this is one of the motivations behind why history is exceptionally vital. Lapham asserts that writing is very significant in learning. He argues that our mind, thoughts and considerations exist in shorthand or schematic structure. Until we illuminate those considerations in their intelligent and syntactic connections. What term could be an exact equivalent word for that idea?), we can undoubtedly miss imperative refinements and associations in knowledge acquisition. Scholars can come to distinguish what they dont yet comprehend when they understand that theyre striving to compose a concise synopsis, and this can help them to bring valuable inquiries up in class. Information technology is progressively influencing our lives in a way which has gotten mundane. The year 2000 has in length been depicted by researchers and storytellers as a time of whats to come, where engineering and innovation might encroach upon our lives significantly more than we could ever have envisioned. As we remained very nearly the new thousand years, this period of electronic enhancement appears to have sneaked up on us without our being completely mindful of any material change. In addition, Lapham argues that â€Å"technology has caused major revolutions in

Mound Builders of Central America Term Paper Example | Topics and Well Written Essays - 1000 words

Mound Builders of Central America - Term Paper Example The mounds are usually shaped square or rectangular, although some hexagonal and octagonal mounds were also found (Gissing 13-14). Thesis Statement: The purpose of this paper is to investigate mound builders of Central America, examine their history, what the mounds represented, whether the mound builders were religious, and the culture and mound building of the Cahokia. Between 2000 B.C. and A.D.1600, the Indians in the ancient Midwest and South thrived for several millennia. Their settlements transformed the untamed wilderness into an advanced network of complex political and economic features. The network was often linked by waterways such as the Missippi River. The first important urban centers were created in North America by the mound builders, from Cahokia in southern Illinois to Poverty Point in northeastern Louisiana (USA Today 12). â€Å"The greatest concentration of mounds lay in the heart of the continent: Ohio, Illinois, Indiana, Missouri† (Silverberg 3). There were subsidiary mound areas in western Tennessee and Kentucky. Nearly every major waterway of the Midwest was surrounded by clusters of mounds. The mounds built in Central America and Mexico were constructed for the same purpose as those in other parts of the continent. Most of the lower mounds would have been constructed â€Å"as foundations for the more important edifices of the mound building people (Gissing 15). Many of the great buildings erected on such pyramidal foundations at Palenque, Uxmal and other places in the region did not vanish over the centuries because they were built of hewn stone laid in mortar. On the other hand, the mound builders beginning their construction works in the lower Mississippi used wood or some other perishable material; therefore there is not even a trace of those mounds to be found today. The higher mounds with broad, flat summits, reached by stairways on the outside, appear like the Mexican

Witch of blackbird pond Essay -- essays research papers

The name of the book that I read was â€Å"The Witch of Blackbird Pond† By, Elizabeth George Speare. The book took place in the year of 1687. Some of the book takes place on a boat called the â€Å"Dolphin,† and then the rest of the book in Wethersfield, in the state of Connecticut. The main characters in the book are Katherine Tyler (her nickname was Kit), Nat Eaton, Uncle Matthew, Aunt Rachel, Hannah Tupper, Kit’s cousins Mercy, and Judith, Prudence, Hannah Tupper, John Holbrook, Goodwife Cruff and Goodman Cruff. One of the problems in the beginning of the book is when she goes to her cousin’s house and was adapting to their way of life; for instance when she got there, they all did not have good clothes and she had really fancy clothes that they would have never worn in their life because they were too expensive. Another problem that she encountered was that she met a lady named Hannah Tupper that lived near Blackbird Pond and she was a Quaker. That’s why she was forced to live there, because no one liked her and she was al so accused of being a witch. Kit made friends with her when she bumped into her in the meadow. This jeopardized her life and that was a problem. She helped Prudence read and write and that was a little risky too.   Ã‚  Ã‚  Ã‚  Ã‚  I mostly identify with the main character kit. I mostly identify with her because she likes to try new things and I like to try new things also. I also identify with her because she likes to explore new places, for instan...

Osmosis Lab

Osmosis Lab March 22, 2013 Amanda L***** Introduction Transport into and out of your cells is important because without cellular transport, the cell could not move material into or out of the cell. This would lead to its inability to survive because cells must take in oxygen and food, and expel waste material that could inhibit the cell from performing in the body. A type of cell transport in particular is passive transport.Passive transport is a kind of  transport  by which  ions  or  molecules  move along a  concentration gradient, which means movement  from an area of  higher  concentration  to an area of  lower  concentration. Passive transport does not require an output of energy. There are 4 main types of passive transport: simple diffusion, facilitated diffusion, filtration, and osmosis. In this lab, we are particularly looking at osmosis and how it affects plant and animal cells.Osmosis is the diffusion of water molecules across a selectively permeab le membrane. In part A of this lab, we submerged the eggs in vinegar overnight, followed by peeling the softened shells from the eggs carefully while trying not to break the membrane the next day. We then recorded any observations we made on the eggs including weight and appearance. Next, we recorded any observations we could make on the carrots and potatoes before we put them into their solution.We then placed the eggs(animal cells), carrots, and potatoes(plant cells) into their solutions and let them stand in their hypotonic and hypertonic solutions overnight followed by observing any changes in weight and appearance the next day. In Part B, we observed an onion cell exposed to distilled water under a microscope, and another onion cell exposed to a saturated salt solution, and drew the two different cells comparing the differences between their exposure to the hypotonic(water) and hypertonic(salt water, corn syrup) solutions. Part APurpose To observe the effects of hypotonic and h ypertonic solutions on plant and animal cells. Hypothesis I predict that the hypotonic solution will cause the plant and animal cells to enlarge due to the difference in concentration on the inside of the cells, and the hypertonic solutions will cause the cells to shrink due to absorption of water molecules in the cells. Materials * 400mL beakers (2) * Tap Water * Eggs (2) * Vinegar * Salt water * Carrots (2) * Corn syrup * Potato strips (2) Procedure Day 1 1. Submerge the eggs in vinegar in a beaker. May have to weigh them down) 2. Leave them undisturbed overnight. Day 2 3. Peel the softened shells from the egg carefully so as not to break the 3membrane. 4. Record any pertinent observations on the egg, carrot and potato strip. 5. Place one egg and carrot in a beaker of water. 6. Place potato strip in a test tube. 7. Place the carrot in a beaker of saturated salt water and use corn syrup for the other egg. 8. Place the second potato strip in a test tube of saturated salt water. 9. L abel the beakers and test tube and place in the cupboard overnight.Day 3 10. Record any pertinent observations. Observations Plant and Animal Cells in Hypertonic Solution: | Solution| Appearance/texture Before| Weight before(g)| Appearance/texture After| Weight After(g)| Egg 1 | Corn Syrup| -translucent-yellowish colour-soft | 77. 53| -opaque-white/yellow colour-feels firm| 51. 17| | | | | | | Carrot 1| Salt solution| -orange-sturdy| 2. 59| -orange-sturdier -appears slightly smaller| 2. 36| | | | | | | Potato 1| Salt solution| -yellowish colour-sturdy| 2. 92| -same colour-sturdier | 2. 85| | | | | | |Plant and Animal Cells in Hypotonic Solution(Distilled Water): | Weight Before(g)| Appearance/Texture After | Weight After (g)| Egg 2| 71. 82| -opaque-orange colour| 84. 10| Carrot 2| 2. 29| -orange colour-not as sturdy| 2. 52| Potato 2 | 2. 49| -yellowish colour-not as sturdy| 2. 98| Part B Purpose To observe changes in plant cells when they are placed in a hypotonic(distilled water) s olution and a hypertonic(saturated salt water) solution. Hypothesis I predict that the hypertonic solution will cause the water to leave the cell, shrinking it due to dehydration from the salt.Materials * Microscope * Microscope slide * Coverslip * Tap water * Saturated salt water * Onion Procedure 1. Prepare a wet mount using distilled water of a thin section of onion skin on a microscope slide. 2. View to draw one to two cells. Use magnification which shows the best detail. 3. Prepare another wet mount using the saturated salt solution instead of distilled water. 4. View and draw one to two cells. Use the same magnification you used for the first drawing. Observations Refer to onion cell drawings. AnalysisMy predictions were both correct in part A and in part B when I stated that the cells would shrink in the hypertonic solution and enlarge in the hypotonic solution. The reason this occurred was because when a cell is immersed into a hypertonic solution, the tendency is for water to flow out of the cell in order to balance the concentration of the solute. When a cell is immersed in a hypotonic solution, it has a tendency to balance concentrations by water flowing into the cell, causing it to enlarge because of the lower concentration of solutes in its surroundings.None of the cells observed had the same weight when removed from their solution meaning they were not isotonic. Had they been isotonic, the solution would have no effect on the cells, therefore when placed in an isotonic solution the cells would tend to neither gain nor lose water. When observing the effects of hypotonic and hypertonic solutions on plant and animal cells, I came to the conclusion that the plant cells did not change much in weight. This is due to their cell walls which make it tougher for the cell to expand.The pressure exerted by water inside the cell against the cell wall is known as turgor pressure. In the drawing of the onion cell exposed to a hypertonic solution, the cell membr ane appeared to be shriveled up inside the cell wall due to its turgidity. Evaluation In part A, I did not experience any errors with the cells themselves, but potential sources of error could have been inaccurate measurements before and after placing the cells in their solution. Other potential sources of error could have occurred while peeling the shell off the egg, causing the membrane to break.In part B, I added too much distilled water to the slide making it difficult to get a good view of the onion cell exposed to the hypotonic solution. When performing a similar experiment in the future, I will be sure to add less drops with the eyedropper to the slide, enabling a clearer view of the cells I am observing. Application Questions 1. If the cells of a fresh water plant are placed in salt water, they will shrivel up due to the concentration difference between the salt water and the contents of the cell (cytoplasm). The water would escape the cell through osmosis causing it to dehy drate resulting in the shrinkage of the plant cell. . The fish that is used to salt water has high solutes and the freshwater is deficient of solutes, so when you place a  saltwater fish  in freshwater, the freshwater will move into the cells, causing them to swell and burst. 3. Grocery stores frequently spray the vegetables because the fresh water enters the plant cells through osmosis and makes them more turgid resulting in longer lasting freshness. 4. The use of road salt in the winter kills the plants alongside the road because the salt causes the cell to enter a hypertonic state. This causes the cytoplasm to move away from cell wall eventually making the plant shrivel up and die.

Your answers should be at least 2 complete sentences if not more! Part I: Observations & Data: Read the Introductory information and the Procedure located in the window to the left of the screen and then perform the laboratory. For your convenience, the data table has been inserted below – fill this one in (the website tends to delete data): Molecules Name |Red Blood Cell: |Red Blood Cell: | | |Net Water Movement In / Out |Appearance of Cell | |Hypotonic Solution | |Blown up and fat | | |Moves in to red blood cell | | |Isotonic Solution | |Normal, did not appear different | | |Moves in and out of red blood cell | | |Hypertonic Solution | |Shriveled up | | |Moves out of red blood cell | | | Elodea: |Elodea: | | |Net Water Movement In / Out |Appearance of Cell | |Hypotonic Solution | |Gets bigger | | |Moves in to Elodea | | |Isotonic Solution | |Appears the same. | |Moves in and out of Elodea (stays the same) | | |Hypertonic Solution |Moves out of Elodea |The inside shrinks and gets smaller | | |Paramecium: |Paramecium: | | |Net Water Movement In / Out |Appearance of Cell | |Hypotonic Solution | |Paramecium blows up and gets bigger. | |Moves in to Paramecium | | |Isotonic Solution | |Seems to stay the same. | | |Moves in and out of Paramecium | | |Hypertonic Solution | |Shriveled up and makes the cell appear smaller. | | |Moves out of Paramecium | | Part II: Questions & Conclusions: 1) Did water move into the cells or out of the cells while they were surrounded by hypotonic solution?Water moved into all of the cells while they were surrounded by hypotonic solution. 2) In which direction did the water move through the cell membrane when the cells were surrounded by the hypertoni c solution? The direction that the water appeared to be moving through the cell membrane was both ways, in and out. 3) Compare and contrast what happens to an animal cell, a plant cell, and a Paramecium cell in a hypotonic, and isotonic, and a hypertonic solution. (Does the cell wall make a difference? ) What seemed to surprise me most is that no matter what cell was used each solution had the same effect of the cells, no matter what kind it was. So no, the cell wall does not appear to make a difference. ) Could Elodea or Paramecium from a freshwater lake be expected to survive if transplanted into the ocean? Explain. Since they both react the same to different solutions I do believe that it is possible for both cells to be transplanted in the ocean and survive. 5) If you were to grill a steak, would it be better to put salt on it BEFORE or AFTER you cooked it? Explain why, USING THE TERMS OF OSMOSIS from this activity. While grilling a steak it is better to put salt on it before yo u grill it so while it is grilling osmosis will occur and it will retain the salt. So instead of it just sitting on top of the steak it will be on the inside. Giving it more flavor of the salt while eating it. ) Why does salad become soggy and wilted when the dressing has been on it for a while? Explain why, in terms of osmosis. The reason why salad becomes soggy and wilted when dressing has been on it for a while is because as it is sitting there osmosis takes place and the salad begins to take in the moisture of the salad dressing, leaving it soggy and wilted. 7) An effective way to kill weeds is to pour salt water on the ground around the plants. Explain why the weeds die, using the principles discovered in this virtual lab. I believe that the weeds would die due to the fact that as the weeds take in what they think is just water only to later dry out by taking in the salt along with it using osmosis.

Enron And Its Impact On Enron s Corporate Bankruptcy Essay

Enron was founded in 1985 by Kenneth Lay and by the mid 90s under the tutelage of Jeff Skilling, it was being touted as a revolutionary company that was destined to change the face of business and the energy industry. However, by 2001 it became clear that Enron’s astronomical growth and sustained profitability was built upon fraudulent grounds. The company was stashing debt but continued to report profits. Employees were taking huge risk and gambling exorbitant amounts and many were outright stealing from the company for their own personal gains. By the end of 2001, Enron’s downfall resulted in the largest corporate bankruptcy in United States history at the time, and more than 20,000 employees were laid off. The company’s fall from grace wasn’t a result of incompetence, instead it was the inevitable consequence of the toxic culture which was incubated and disseminated by Enron’s top management to all other aspects of the company. Enron’s st rong culture became a liability because culture defines what is important to the organization and informs employees about how things are meant to be done. As I will demonstrate through various examples of Enron’s questionable business tactics, its potent corporate culture was low on attention to detail while being high on aggressiveness, risk taking and outcome orientation. This combination of factors created the climate for unethical behavior to become a deep-rooted norm within the organization.
