Slaters Investigation

Aim. The aim of this investigation is to find out how Slaters react to an increase or decrease of the temperature in its surroundings. Hypothesis The speed of the Slaters will increase when the temperature of its environment is increased or decreased from its preferred range, so it ensures that they spend less time in unfavorable conditions to avoid desiccation. Method 1. This experiment is done using a water bath to change and control the temperature being trialed.The water bath will have a lid on it in order to keep the light intensity and humidity as constant as possible. 2. Ice and warm water would be used to the temperatures being trialed in this experiment. The temperature range that I am going to be using is 10Â °C,15Â °C,20Â °C,25Â °C,30Â °C. The temperature will be controlled between each Slater test by measuring the temperature of the water with a thermometer and adjusting the temperature to ensure that each Slater test is accurate and fair.The light intensity and humi dity of the environment would be monitored throughout the experiment. 3. A beaker with a piece of paper stuck to the bottom of it will be placed into the water bath once the water bath have adjusted to the temperature being trialed. In order for the test to be accurate, I would give the beaker and paper 2 minutes to adjust to the temperature that I am trialing before putting the slater in it. 4.Starting with the temperature at 10Â °C, I would draw a dot at the center of the paper in the beaker as a starting point. Each Slater will have 60 seconds and I will start once the slater have touched the dot on the paper. In order to measure the distance that the Slater have travelled in that 60 seconds, I will mark the position of the Slater every time it turns direction of movement in each test, at the end of each Slater test the markings would then be joined together to show the complete trail of the Slater

The eNotes Blog Fact in Fiction The Top 20 Harry Potter SpellsDeciphered

Fact in Fiction The Top 20 Harry Potter SpellsDeciphered With the release of the last Harry Potter book,  Harry Potter and the Cursed Child, Potterheads everywhere can rejoice in one final installation of this epic tale. We used this as a chance to revisit some of the most iconic words uttered throughout the series- spells, charms, and curses- and find the root of their meaning. 1. Expecto Patronum A charm that creates a Patronus.  Expecto means I await in Latin, and Patronum means patron. We can surmise that Patronus, Latin for guardian, is what is being awaited. Expecto Patronum = I await a guardian. 2. Accio A charm that summons an object.  Accio simply means summon in Latin. Accio = summon. 3. Wingardium Leviosa A charm that makes objects fly.  This one is a sort of pseudo-Latin.  Wing can simply be taken from the English word, and  levis is Latin for lightweight. Together, these words make sense in a charm that makes things fly. 4.  Expelliarmus A charm that disarms ones opponent.  Expello  means to banish and  arma is Latin for weapons. Expelliarmus = to banish weapons. 5.  Lumos A spell that creates light at the tip of the casters wand.  Lumen is simply Latin for light. Lumos = light. 6.  Alohomora A charm that opens locked objects. J.K Rowling claims that  alohomora is a West African word meaning friendly to thieves. It seems to make perfect sense, since what thieves wouldnt want a door unlocked? 7.  Avada Kedavra A curse that murders ones  opponent. Avada Kedavra  seems to actually be the Aramaic form of the infamous phrase abracadabra, meaning let the thing be destroyed. 8.  Sectumsempra A spell that inflicts slash wounds.  Sectus  is Latin for cut up and  semper is Latin for always. Sectumsempra = always cut up. 9.  Obliviate A charm that erases memories. From the Medieval Latin word  obliviscor, which means to forget, obliviate literally means forget. 10.  Riddikulus A spell used to defeat a Boggart. Riddikulus seems to be a made-up spelling of the Latin word  ridiculus, which means the same as  ridiculous in English. This in itself is derived from  rideo, which means to laugh at or to smile. 11.  Imperio A curse that allows the caster to control a person.  Imperio is Latin for command. As a curse giving total control over someone, it checks out. Imperio = command. 12.  Petrificus Totalus A curse that paralyzes ones opponent. The Greek  petros means rock or stone, and the Latin  facio means cause to happen. That coupled with the Medieval Latin  totalis or classical Latin  totus, both meaning whole or entire, leaves petrificus totalus meaning to cause the entire thing to turn to stone.   13.  Stupefy A spell that knocks out ones opponent.  Stupeo means to be stunned in Latin, and  fio is Latin for cause to happen. Stupefy = cause someone to be stunned. 14.  Crucio A curse that inflicts torturous  pain on ones opponent.  Crucio literally means torture in Latin. How easy is that? Crucio = torture. 15.  Incendio A spell that starts a fire.  Incendo is Latin for set fire to. Incendio = set fire to. 16.  Aguamenti A charm that shoots water from the tip of ones wand.  Aqua in Latin- or  agua in Spanish- means water, and  augmen  is Latin for  growth. Aguamenti = growing water. 17.  Expulso A charm that makes blocking objects explode.  Ex translates to away in Latin, and  pulso means I strike. Expulso = I strike things away. 18.  Protego A charm that causes a spell to reflect onto its caster. Another direct translation, the Latin word  protego means to cover or  to protect. In this case, it applies to the charms ability to protect the caster. Protego = protect. 19.  Reducto A spell that explodes solid objects.  Reducto means having been reduced in Latin. Contextually, it seems that this applies to the objects being reduced into their most basic form, i.e. they are exploded into much smaller pieces. 20.  Reparo A spell that repairs broken or damaged objects.  Reparo is Latin for restore or renew. Easy, right? Reparo = restore. Need a refresher about the previous books?

Feckless

Feckless Feckless Feckless By Maeve Maddox A reader has called my attention to a surge in the use of the word feckless in the American press. A Web search garners 1,550,000 hits. Feckless derives from feck, a dialect word possibly formed by a linguistic process called aphaeresis: â€Å"omission of one or more sounds or letters from the beginning of a word.† Examples of aphaeresis include: squire from esquire and coon from raccoon. Feck, which is documented as early as the 14th century, is probably a shortening of the noun effect. Feck is â€Å"energy and gumption.† A person with feck gets things done. When used to refer to a thing, the adjective feckless means, â€Å"valueless, futile, or feeble.† Used to refer to a person or a person’s actions, feckless means, â€Å"lacking energy; weak, helpless.† In modern usage, feckless is used chiefly as a synonym for irresponsible or shiftless. This latter use of feckless is especially common in the British press in headlines and articles relating to social welfare programs: Britains most feckless father? Unemployed dad of 10 is expecting FOUR more children –The Telegraph. Lets get the feckless to buy food not fags and booze –MailOnline. No one would consider her [a young unmarried mother of four children, by two different men, and expecting her fifth] to be anything other than feckless and irresponsible. –The Independent. The Oxfam report – â€Å"Walking The Breadline,† published in June this year, states that half a million people in the UK rely on food banks. Yet the Government puts their fingers in their ears, blaming feckless parenting and scroungers. –The Guardian. Here are some examples in contexts other than discussions of welfare recipients: Given their feckless track record, would you really trust Apple with (even more of) your digital life? –Source uncertain; the comment appears on numerous sites. One striking feature in all three works is how badly the men do; how feckless they are, how treacherous, weepy, self-obsessed and violent. –Review of a collection of three short stories by Bernhard Schlink. Because the usual use of feckless is to describe people or actions lacking in will or responsible purpose, some of the examples I found left me a bit puzzled: Delete a Feckless Effect from Filler Edgar Steele’s Feckless Racism Here are some sure fire home remedies and tips to get rid of your feckless and lifeless hair. The opposite of feckless–feckful (powerful, effective, efficient, vigorous)–is used seriously in an OED citation dated 1568: I culd nocht cumwithout sum gret and fecfull purpois. [I could not comewithout some great and feckful purpose.] Anyone using the positive adjective feckful nowadays would be aiming for humorous effect, as in this 1990 quotation from The New York Times: The unfailingly feckless Bertie Wooster and his valet, the formidably feckful Jeeves. Sometimes feckless is the perfect choice, but sometimes not. Here is a selection of words that might serve better in some contexts: good-for-nothing idle indolent inept irresponsible lazy ne’er-do-well no-account slothful sorry useless worthless David Auburn, playwright and contributor to the Oxford American Writer’s Thesaurus, says this about feckless: The obscene-sounding first syllable gives punch and an air of harsh condemnation to the synonym for irresponsible, conveying â€Å"not merely irresponsible but also unforgivably blithe, and in one’s blitheness, causing great harm.† Want to improve your English in five minutes a day?

Corporate Finance Assignment Essay Example | Topics and Well Written Essays - 1750 words

Corporate Finance Assignment - Essay Example Sales increase from year 1 to year 2 by 1.5 times, but in the 3rd year it appears that the sales only increase by 1.33 times, which shows a decline as compared to the previous financial year. Variable cost is included as a percentage of the sales for the month, which is 30% of the sales for the year. All the fixed costs are assumed to be directly attributable to the project and thus are included in the cash flows. As mentioned in the project, the useful life of the facility will be three years, thus it will be depreciated on a straight line basis over three years. Depreciation is a non-cash item, but it is included in the cash flow forecasting because of the tax shield, since depreciation is also tax deductible. In first year, the company will have taxable loss, so it is assumed that the company will have taxable profit in the future, against which this taxable loss will be utilized, resulting in tax savings. Depreciation is added back and the net cash flow is discounted through the use of the required rate of return in order to calculate the Net Present Value. 2. The principal risk of the project There are several principal risks that surround the project. Hi-Tech Industries operates in the technology industry, which is subject to rapid changes in many fields such as standard equipment, operating procedures, and laws and regulation. The project under consideration requires a careful estimation of all the relevant costs and revenues; a misjudgment in the forecast will cause an error in the project net present value, which might result in the acceptance of a project which is not financially viable. The initial capital expenditure must be carefully projected. In order to do so, it is of prime importance that the company obtains quotations from several companies in order to project the current market value of component. An artificially higher price will put a declining effect on the net present value of the project, and an artificially lower price will cause the o pposite. Another risk that is present in the financial appraisal of the project is that the company might not have estimated the correct useful life of the equipment. The IT related hardware and equipment are subject to becoming obsolete at a greater pace as compared to the other kinds, so this risk is present. While making an investment appraisal decision, it is imperative to consider the impact of inflation in the future cash flow. The information provided does not include any relevant information about the price inflation over the three year period, which can significantly impact the expected NPV. The director of the company must also consider the sources from which the financing will be obtained for the investment. Financing decision is significant, as the company would have to pay finance charge to the bank or any other financial institution, and the company must have enough cash flow in the future for the payment of these finance charge. In order to commence any investment ven ture, the director must receive the approval of the shareholders.

Introduction to Statistics - Essay Example a) Proportion of affected patients was with the 95% confidence interval for the proportion of stroke patients who become clinically depressed given by . The confidence interval indicates with a confidence coefficient of 0.95 that the true proportion of stroke patients who become clinically depressed lies within this interval. b) To evaluate the claim of the health magazine, we check whether the confidence interval contains 60% of stroke sufferers. Since 0.60 is within the confidence interval, we conclude that the claim by the health magazine is consistent with the observed data (Mendenhall en Sinchich). c) The assumptions for the confidence interval to be valid include large sample size to ensure the validity of the normal approximation. The sample size of 79 is large enough to guarantee the validity of the normal approximation. d) Sample size to be used to achieve a 99% level of confidence that the sample proportion of stroke patients suffering from depression is within 0.025 of the true proportion is computed from the following formula. b) The main assumption for the validity of the confidence interval computed is that the sample should be drawn from a normal distribution or asymptotically, it should tend to a normal distribution. This assumption is violated since from the boxplot, the distribution of the temperature is right skewed. This is evident from the unequal length of whiskers of the boxplot, with a longer whisker for data to the right of the

Globalization case Study Example | Topics and Well Written Essays - 500 words

Globalization - Case Study Example However, this assumption is not true as the social dynamics witnessed in Tunisia has revolutionized this conservative thought and new behaviors have been adopted. As at 2013, 32% of the whole population of Tunisia had taken alcohol by 40 years and this implies that the few existing factories cannot sufficiently meet the existing demand (Angel-Urdinola, 2015, p.112). The company seeks to use this entry market strategy so as to sell its wine and spirits products owing to the cultural and political environment in Tunisia may not be that favorable to set a manufacturing company at the moment. The country is, in most cases, marred with constant violence and interreligious wars animosity (Angel-Urdinola et al., 2015, p.67). The deep-rooted Arabic culture and language may not also favor foreigners who have little or no mastery of this environment. It is, therefore, advantageous if the manufacturing industry is set in a different country and goods supplied to consumers through intermediaries based in Tunisia who understand the diversities of the local market. This strategy will largely help to solve the global local dilemmas that the country is likely to face such as cultural issues, language barriers, lack of raw materials and political interferences among others as the intermediaries are able to come in between the producer and the consumer and facilitate free flow of the products. The agents are able to effectively inform both the buyer and the exporter about issues concerning the products based on first-hand research (Hisrich, 2010, p.98). Tunisia’s policies on trade instruments such as tariffs, quotas and taxes among others simplify the business process. There are limited stringent rules that block foreign investors as the government encourages international investment to promote the economy. There are no meaningful barriers to market

Waiting for Death in `A Rose for Emily` and `Old Ladies Home’ Essay Example for Free

Waiting for Death in `A Rose for Emily` and `Old Ladies Home’ Essay William Faulkner wrote, â€Å"A Rose for Emily† at a time when society was undergoing change. The South had lost the Civil War and the southern people were finding it hard to let go of the past. Emily is the symbolic representation of this resistance to change. She becomes numb emotionally simply carrying out the routine of life without any characteristic resistance while the people around her become onlookers. Similarly, Sylvia Plath’s poem â€Å"Old Ladies Home† relates the dehumanization of the inhabitants. The people in the Home have ceased to exist for the outside world. The women in the Home are existing like insects quiet and without character as the people around them move about, detached and cold. Analysis of the Theme and Symbolism In Faulkner’s short story, Emily, after her father’s death she became a recluse and stopped living. Her life became a part in history and it seemed she and the people around him simply waited for her death. She was described as, †¦a slight woman, though thinner than usual, with cold, haughty black eyes in a face the flesh of which was strained across the temples and about the eye-sockets as imagine a lighthouse-keepers face ought to look (Kirszner, 58). Faulkner shows the concept of death and how death can become a release when life becomes status quo. The reader is told in great detail about the position of Emily and her father in the town and the manner in which their life has changed. In Plath’s poem we read about the ladies wearing black and being ‘sharded’ in it. The words used to describe these women are, â€Å"Sharded in black, like beetles, Frail as antique earthenwear One breath might shiver to bits†¦ Age wears the best black fabric Rust-red or green as lichens. † The decay of the fabric represents the decay of their life. The nurses call them ‘ghosts’ and the beds are said to resemble ‘coffins’. The nature of the Home and the change in their life from youthful to aged shows the contrast of life to death. The concept of death and decay is prevalent in the story by Faulkner as well for he describes the decaying house as an eyesore among eyesores (Kirszner, 55). The decay represents the decay of Emily’s family’s position in society. The decaying body of Homer found after Emily Greison’s death also represents how things can get corrupted when change is not accepted. Emily was so steeped in her life in the past that she could not function in the present. Her father’s death and the death of her fiance caused her to give up on life and start a slow wait for her own death. The words Faulkner used to describe Emily and her situation included the smell and people going to her slunk around while the actual reality of Emily’s life became a tableau for the people of the town shown through the words, â€Å"We had long thought of them as tableau, Miss Emily a slender figure in white in the background, her father a spraddled silhouette in the foreground, his back to her and clutching a horsewhip, the two of them framed by the back-flung front door (Kirszner, 57). † Both Plath and Faulkner used the symbols and imagery of decay to show the progress of death. As the story and poem progress, death becomes the ultimate goal. The words and imagery in both the texts shows the frailness of the women. Through a description of the house Faulkner showed the change in Emily’s life. Her house decayed from a mansion to one that became a representation of failure and death. The crumbling walls became a source of fascination for the people and Emily ceased to exist as a person to them, rather she became a representation of the past [Allen, 1984]. The townspeople did not try to reach out or help her, they just focused on her life in fascination. Plath too, created a picture of the old women as decaying objects rather than human beings. They are described as insects and their progression towards death becomes inevitable. The words, ‘The old women creep out here†¦Ã¢â‚¬  are used to describe them and the word ‘creep’ is similar to Faulkner’s use of ‘slink’ to show the dehumanization of Emily and the others view of her as a symbol rather than a human. We see Plath go on to write, ‘Needles knit in a bird-beaked Counterpoint to their voices: Sons, daughters, daughters and sons, Distant and cold as photos†¦Ã¢â‚¬  The relationship between the women and their relatives is similar to the one Emily had with the townspeople. There was no warmth or love between them and the only connection was one of the past. The women’s relatives came out of a sense of obligation and duty and the visits were like looking at old photographs with no feelings. Like Faulkner writes, â€Å"Thus she passed from generation to generation dear, inescapable, impervious, tranquil, and perverse (Faulkner, 5), Emily’s life stood still. Her relationship with the world at large became stagnant and there was nothing to associate her life with being alive. Similarly, Plath [2009] uses the words, Age wears the best black fabric, to show how the women have stopped living and are in a constant state of mourning. They cling to every morsel of life and their very fragility shows the fragile threads of life and death. Conclusion: As we have seen Plath and Faulkner both wrote about the decay of life and the approach of death. They focused on the slow decomposition of human life physically and emotionally and how people become a ghost of their old selves as death approaches. However, while conceptually the similarities in the two texts may seem extraordinary there is a basic difference between these two narrations. Faulkner, wrote more of the decay and destruction of life figuratively, and how through the resistance to change humans become corrupted in their life. He wrote more of the death of a way of life, creating Emily and her life as a symbol of societal change. Plath, on the other hand discussed death in the physical concept. She presented the decomposition of human life and the loss of individuality as the progress of old age becomes eminent. The ladies in the poem were waiting for their death and had become mere shells of their former body. This stark contrast between the two texts creates a broader theme which suggests that without change human life ceases to exist and with the decay of the human body, life is but a wait for death.
