Lab Report Conclusion Essay Example

Lab Report Conclusion Paper Conclusion In this experiment, we measured the mass of 4 gases; oxygen, carbon dioxide, helium, and lab gas. We took a Copilot bag, and turned into a non-stretchy balloon, and filled with each gas and measured the apparent mass then calculated the actual mass, then find a ratio between the mass of oxygen and the other gases. We tried to keep the pressure about the same each time so our calculations would be more accurate. We found out that the heaviest was carbon dioxide, and the lightest was helium. In fact, helium and lab gas had a density below 0. Anyways, it turned out that our apparent masses were very different from our actual mass calculations; for example oxygens apparent mass was 28. Egg but its actual mass was 4. Egg. We also found the ratios, and after collecting class data, our carbon dioxide ratio was 1. 39/g, our helium ratio was . 21/g, and our lab gas ratio was . 59/ lag. Then we had to come up with two hypotheses to figure out why one gas is heavier (denser) than another? Well, we came up with hypothesis : The different molecule mass hypothesis, and hypothesis #2: The more molecules in the same volume hypothesis. After having a class discussion, turns out that hypothesis one is more reliable due to Avogadro hypothesis; if two gases at the same temperature and equal volume contain equal amount of molecules. So according to the statement above, the carbon dioxide molecules must be 1. Xx bigger than an oxygen molecule, a helium molecule must be . Xx bigger, and . Xx bigger than an oxygen molecule.

Top Ten Confused Words [T]

Top Ten Confused Words [T] Top Ten Confused Words [T] Top Ten Confused Words [T] By Maeve Maddox My cumulative list of â€Å"words commonly confused† continues with ten that begin with the letter T. The confusion relates to spelling or meaning. 1. taught / taut The word taught is the past tense of the verb to teach. It is also used as an adjective to mean instructed: â€Å"Howard Phillips Lovecraft, weird fiction writer and primogenitor of modern horror fiction, was a self-taught writer.† The adjective taut means â€Å"pulled tight.† A common error is to spell taut as taught, as in this fishing advice in a magazine called Backpacker: INCORRECT: Use more weight to keep the line taught. CORRECT: Use more weight to keep the line taut. 2. titivate / titillate The verb titivate means â€Å"to spruce up, to make more attractive.† Ex. We decided to titivate the kitchen with new cabinets and countertops. The verb titillate means â€Å"to excite the senses or imagination in an agreeable way.† Ex. Camilla Ochlan has crafted a supernatural mystery-thriller that  will titillate  the palate of even the most discriminating  Sci-Fi Fantasy  reader. The error is to mix them up, as in this example from a restaurant site: INCORRECT: We are sure to have something to titivate your tastebuds. CORRECT: We are sure to have something to titillate your taste buds. 3. tortuous / torturous The adjective tortuous means â€Å"full of twists; complex.† The  tortuous road  we had to climb had one steep and narrow curve after another all the way to the  top. The adjective torturous means â€Å"full of pain or suffering. Ex. More significantly, the book prominently features a scene in which the heroes resort to torturous means in order to extract vital, life-or-death information. The error is to mix them up, although some might argue that a thing can be full of twists and pain at the same time. 4. tenant / tenet A tenant is someone who rents property. Ex. The tenant always paid her rent on time. A tenet is a principle or belief. Ex. The tenet to love one’s neighbor is stated in Leviticus 19:18. The error with these words goes both ways: INCORRECT: This course is designed to give the students an overview of the basic  tenants  of Christian Doctrine. CORRECT : This course is designed to give the students an overview of the basic  tenets  of Christian Doctrine. INCORRECT: Most importantly, stay informed about your rights as a  tenet. CORRECT: Most importantly, stay informed about your rights as a  tenant. 5. than / then The word than is a conjunction used after a comparative adjective or adverb to introduce the second member of the comparison. Ex. She thinks her border collie is smarter than my boxer. The word then is an adverb that refers to a specified time, past or future, as opposed to the present. Ex. We didn’t have enough money for luxuries like books then. 6. through / threw Through is a preposition used to convey the idea of entering the inside of something and coming out the other side: They always go through the churchyard on their way home. Threw is the past tense of the verb to throw: He threw the ball over the fence. The usual error is to spell through as threw, as in this example from a geocaching site: INCORRECT: You will need to go  threw the tunnel  to access this cache. CORRECT: You will need to go  through the tunnel  to access this cache. 7. throws / throes Throws is the third person present singular of the verb to throw: He throws with his left arm. Throws can also be the plural of the noun throw that refers to a light blanket: She keeps throws on all the couches and chairs. Throes is a noun that means â€Å"severe pains.† Figuratively, it can mean â€Å"difficult times.† Ex. The pirate lay in the last throes of death. The Smiths are in the throes of divorce. 8. track / tract As a noun, track is a mark or series of marks left by the passage of something. The Mountie caught the fugitive by following the track left in the snow. One meaning of the noun tract is â€Å"a book or written work treating of some particular topic.† Ex. The evangelists passed out tracts on the subject of salvation. 9. till / ’til Till has different functions, one of which is that of conjunction with the same meaning as until: ‘to the time that; up to the point when†: I will sit here till he agrees to speak to me. The form ’til is an unnecessary shortening of until. The error is in thinking that till is a shortening of until. 10. torpid / turgid The adjective torpid means benumbed or â€Å"devoid of the power or motion of feeling.† Ex.  Even when he was awake he was completely  torpid. The adjective turgid means swollen, distended, puffed out. The word is applied figuratively to language with the meanings inflated, pompous, bombastic. Examples of literal and figurative use: My arm was turgid where the snake had bitten it. Eventually, the movie surrenders to the most turgid Hollywood speechifying and sentimentality, far more so than the original permitted itself to do.

A comparison if the influence of the past and the present in Snow Falling on Cedars and Chocolat.

A comparison if the influence of the past and the present in Snow Falling on Cedars and Chocolat. Joanne Harris’ novel Chocolat and Scott Hicks’ film Snow Falling on Cedars use characters and their interactions to explore the influence of the past on the present. Both texts reveal the influence of past relationships on their major female and male characters’ present lives. Where Harris’ focus is family relationships, Hicks also explores the impact of a past romantic relationship. Using a dual first-person narrative, Harris relies on the reminiscences of her central characters to convey the connection between past and present, whereas Hicks employs a non-linear structure of flashbacks interspersed with the present to make this link. Both texts use the impact of racism on its victims to reveal that not only individuals live in the shadow of the past, but also the entire community. Both Chocolat and Snow Falling on Cedars depict how a childhood father figure shapes the lifestyle of their main male character. Harris’ dual first-person narrative voice allows the reader access to antagonist Reynaud’s thoughts and memories as he speaks to Mon Pere, who was once his childhood mentor; whereas Hicks juxtaposes flashbacks from several characters’ perspectives with the present to reveal how the past shaped protagonist Ishmael’s (Ethan Hawke) life. One such flashback reveals that as a child Ishmael learned to use the newspaper press, his father commenting that he would â€Å"make a newspaper man out of (him) yet†. This is coupled with the present, where he is reporting on the trial of the Japanese-American Kazuo for murder, fulfilling his father’s wish. Like Ishmael, Reynaud’s father figure determined his career. Reynaud comments that as a child he â€Å"compromised (his) soul† for the priest, who persuaded him to s et the gypsy boats alight, and as a result he caused the death of two â€Å"sleepers† who â€Å"failed to waken†. However, he was â€Å"absolved† by Mon Pere and set firmly on the course of becoming a priest later in life. He now attempts to live up to Mon Pere’s example in his â€Å"crusade† against the recently arrived gypsies. Unlike Mon Pere’s influence on Reynaud, Ishmael’s father instilled in him strong opposition to racism. A montage sequence shows Ishmael’s attempt to write an article about the â€Å"unfair† trial, interspersed with close-ups of his father’s glasses, the evidence that can save Kazuo, and a photo of Hatsue (Youki Kudoh), his first love. This interaction between past and present reveals the decision Ishmael faces between presenting evidence to save Hatsue’s husband, Kazuo (Rick Yune) from conviction, as his father would have done, or to indulge his personal desire to withhold it out o f anger with Hatsue, who broke his heart. Near the end of the film, Ishmael decides to put the evidence forward. While in Chocolat Reynaud’s present is negatively affected by the influence of Mon Pere’s past racism, in Snow Falling on Cedars, Ishmael’s father shaped his morals, which positively affects his present. As well as their careers and personal beliefs, Reynaud and Ishmael’s insecurities and fears stem from their father figures. Through his monologue, Reynaud reveals that as a child, he caught his mother engaging in a sin â€Å"of the flesh† with the priest. His shock that Mon Pere was even â€Å"capable of sin† made him realise that â€Å"nothing was safe† and created his desperate fear of temptation. His attempts to realise his idealistic view of priesthood and resist temptation where Mon Pere could not, control Reynaud’s lifestyle. Harris uses vivid imagery in Reynuad’s dream of dying â€Å"beneath (chocolate’s) tender gluttony,† a â€Å"cumulation of every temptation ever known,† to reveal his fear of slipping further towards temptation, despite his increasing self-denial during Lent. In contrast, Hicks reveals through dialogue that unlike Reynaud’s attempts to transcend his forerunner, Ishmael’s life is sh aped by his insecurity that he is â€Å"only half the man his father was.† However, Ishmael ultimately lives up to his father’s example and overcomes his sense of injury, the war and his anger at Hatsue, to save Kazuo and move on with his life. Nels’ (Max Von Sydow) comment, that Ishmael is â€Å"sounding just a little like (his) father†, confirms this success. Harris, in contrast, reveals that Reynaud’s desperate attempts to â€Å"weed† out the metaphorical â€Å"dandelions†, which represent the temptation of â€Å"La Cleste Praline Chocolaterie Artisanale† and the indulgent gypsy lifestyle, lead to his destruction. He becomes delirious, imagining Denise Arnauld â€Å"eating in the confessional†, and is flooded with â€Å"irrational thoughts† of â€Å"devil worship† when he sees the flames of Vianne’s â€Å"flambed pancakes† at the gypsy campsite. Ultimately, his fear that the temptation of c hocolate and indulgence will â€Å"undermine the church† drives him to attempt to destroy Vianne’s chocolate festival, leading to his own downfall. Harris uses reminiscences within Vianne’s narration, and Hicks uses flashbacks juxtaposed with the present, to explore the impact a past relationship has on the present of their protagonists. A close-up of protagonist Ishmael watching Hatsue through a symbolic barrier of balcony bars during the opening of the trial, coupled with their first conversation where Hatsue commands him to â€Å"go away†, introduces their estranged relationship. Flashbacks reveal the illicit nature of Hatsue and Ishmael’s past romance, as Ishmael comments that Hatsue’s â€Å"friends would† find their relationship inappropriate. Their fear of being caught is reflected in the dimly lit, secretive setting of the cedar tree. Hicks combines a voice-over of Hatsue reading a letter, in which she reveals her understanding that she and Ishmael â€Å"could never be right together†, with swelling non-digetic music and a final close-up of Ishmael’s amputated arm. This rev eals that the strain of societal disapproval caused Ishmael and Hatsue’s relationship to fall apart, with Ishmael’s physical injury symbolising the long-term damage created for him by the failure of the relationship. Hicks reveals that Ishmael still resents Hatsue’s choice to end their relationship when Ishmael’s voice breaks as he suggests that he should â€Å"write an article about unfairness and all the unfair things that people do to each other†. Whilst Hicks combines soundtrack and images, Harris uses the metaphorical image of the â€Å"Black Man†, a figure that embodies Vianne’s mother’s greatest fear: losing her child to the church authorities, to reveal that Vianne’s relationship with her mother was strained by the constant presence of this fear. This negatively affects the adult Vianne. She too fears the loss of her daughter Anouk, despite her understanding that â€Å"children are born wild† and must go t heir own way. She also continues to feel the presence of â€Å"the black man† even after her mother’s death; in Lansquenet her â€Å"black man† is the antagonist Reynaud. The present of both protagonists is negatively affected by their past until Vianne can overcome her fear of the â€Å"Black Man†, and Ishmael can overcome his resentment and save Kazuo, Hatsue’s husband, from conviction. Ishmael’s escape from the influence of the past is symbolised by his and Hatsue’s final embrace, as earlier in the film he begged to â€Å"hold† her â€Å"for a few seconds† so he could â€Å"walk away and never speak to her again†. Harris also symbolically reveals Vianne’s ability to overcome the negative influence of her mother, when Vianne chooses to burn the tarot card of â€Å"the black man† which dictated her mother’s life. Following this is the revelation that Reynaud is â€Å"a fool to himself, a carnival mask†, which allows her to let go of her fear of â€Å"the black man†, the strongest negative legacy from her mother. Thus, both Harris and Hicks use their protagonists to pr esent the human ability to overcome the emotional baggage of past relationships. The life choices of both Vianne and Hatsue, are influenced by their childhood relationships with their mothers. Harris uses â€Å"the wind song† motif â€Å"V’l l’bon vent, v’l l’joli vent†, and the pull â€Å"the moving hot wind† has for Vianne, to reveal that Vianne’s childhood â€Å"chase around Europe† left her with an inability to settle down. Her childhood also created Vianne’s interest in cooking; she refers to recipes as â€Å"signposts along (her) erratic path†. This determined her choice to run a chocolate shop, the foundation of her present lifestyle. As Vianne’s childhood directly shaped her present lifestyle, so Hatsue’s childhood governed her marriage and relationship decisions. Instead of Harris’ abstract imagery, Hicks cuts from the realistic romantic close-up of Hatsue and Ishmael together in the cedar tree, to a dialogue Hatsue has with her mother, to reveal that Hatsu e’s mother taught her â€Å"to be Japanese†, to â€Å"stay away from white boys† and â€Å"marry one of (her) own kind.† This conveys the environment in which Hatsue grew up, where racial segregation between Japanese and Anglo-Americans was accepted. Hicks portrays this segregation using a mid-shot of the school bus, where Japanese and Anglo children sit on opposite sides of the aisle. Hatsue’s understanding that her relationship with Ishmael was â€Å"wrong† for the society in which they live, and her choice to instead marry the Japanese-American Kazuo, reflects her mother’s influence and Hatsue’s recognition of this segregation. Through the influence of past racism on the victims’ present, both texts suggest that it is not only individuals who are affected by the past, but the wider community. Harris uses the minor character, Roux, to explore racial prejudices and society’s reaction to the gypsies, while Hicks uses the community’s response to minor character Kazuo’s trial to convey racial tension. Within his narrative, Reynaud recalls that as a boy he committed arson and drove the gypsies out of the village, revealing past prejudice in Lansquenet. In contrast, Hicks uses flashbacks of Hatsue’s family to reveal that thousands of Japanese were sent to prison camps as internal enemies during the Second World War. This is the basis of Kazuo’s fear that he â€Å"would be made the victim of prejudice†, which leads to his attempt to conceal evidence of his presence on Karl’s boat by removing his spare battery, ironically making himself look more guilty. Unlike the images used by Hicks, Harris relies on dialogue to reveal Roux’s fear of being victimised when he thinks he has accidentally â€Å"killed† Armande. In his panic Roux angrily tells Vianne that people â€Å"will say (he) attacked† Armande and he is afraid to go â€Å"back there†. Minor character Jolie’s wonder at â€Å"what he was doing here to reveal that there is foundation for his fear. In Snow Falling on Cedars, racism also remains. It surfaces during the crisis of the court case, where Karl’s wife comments that â€Å"you can’t read Japs†, and Kazuo’s lawyer, Nels, comments that the â€Å"prosecutor† used racism against Kazuo when he suggested that the jury â€Å"look at his face†¦ assuming (they) would see an enemy there†. Both texts reveal that the victims of past racism are affected in the present through their fear that they will again be victimised, a conviction furthered by the continued presence of racism in their society. While both authors reveal that old insecurities, resentments and fears, often drive the actions of individuals and the wider community, they imply that this negative influence on the present must be overcome. Harris reveals that Vianne cannot grow as a person until she overcomes her fear of â€Å"the black man† which stems from her childhood. Hicks reveals that Ishmael must overcome his resentment of Hatsue, so that he can save Kazuo from conviction. This allows him to overcome his sense of moral inferiority to his father and grow as an individual. In Chocolat, Reynaud serves to show the danger of never overcoming the past, which leads to his destruction, as he escapes his town Lansquenet in disguise, losing his job and purpose. Hicks uses flashbacks to reveal that within the community there is a continuation of racism from the Second World War, while Harris relies on reminiscence within Raynaud’s narration to reveal that this racism stems from the stereotypical view of gypsies as â€Å"vermin†. In both texts, minor characters are used to highlight the danger of the communities’ inability to overcome racist ideas, which, in conjunction with the struggle of individual characters with the past, compounds the authors’ message that individual and communal growth can only be achieved by overcoming the past’s destructive influence.

Critical Article Review Example | Topics and Well Written Essays - 500 words

Critical Review - Article Example His main aim in writing this article is to show the role black residents of Tennessee played in the Civil War in Tennessee, and the impact their presence had on the victory of the Union army. The article is a good read, although it is riddled with a lot of facts and figures regarding the United States Colored Troops regiments. This is one of its strengths as well; the effort Lovett must have taken in writing this article is apparent by his extensive referencing as well as his quotation of figures regarding the Colored Troops regiments. At the end of the article, he has presented a fact sheet, detailing the Colored Units and their battles and engagements between the period of 1863 to 1866. This is a clear sign of his methodical research and attention to detail. Lovett also tries to capture the human emotion behind the involvement of slaves in the Union Army. He gives anecdotal references, of course well-documented, with regard to the atmosphere of Tennessee and the condition of blacks therein. The article is clear in pointing out the aversion the rebel army had to arming blacks due to the racism very much prevalent and rife in the South, and this, Lovett, points out is what caused their defeat in the end. He makes out a very good case regarding how the Union Army took the opportunity of enlisting blacks and, thus, won the war.

Balanced Diet for an Adult Essay Example for Free

Balanced Diet for an Adult Essay Food is an integral part of human life providing energy for cellular activities to keep us healthy. According to World Health Organization (2013), healthy nutrition is ingesting an adequate and well balanced diet in relation to the body’s dietary needs and when combined with regular physical activities is the cornerstone to good health. A diet containing the right portions of all the five food groups of the Eatwell Plate (figure1 and appendix1 for recommended servings) known as a balanced diet will provide the organic macronutrients including proteins, carbohydrates and lipids and the micronutrients, vitamins and minerals to sustain life. Only ingested carbohydrates, proteins and lipids will count towards total caloric intake and will be digested into monomers like glucose for absorption and assimilation. National Health Service (2012) recommends daily caloric intake of 2500Kcal and 2000Kcal which will be derived from the proteins, lipids and carbohydrate sources in a diet for average adult males and females respectively. Age, sex, health condition and physical activities influence dietary needs. This essay will discuss a balanced diet for an adult including the structure, sources, functions, recommended daily allowance (RDAs), deficiency and excessive effects of the macronutrients. Also the micronutrients and water which are not considered as nutrients will be discussed. THE FOOD PYRAMID [pic]Figure1 (NHS 2011) Carbohydrates contain carbon, hydrogen and oxygen. British Nutrition Foundation (2013), recommends that 47.7% (203g) and 48.5% (275g) of daily energy should come from carbohydrates for females and males respectively with 29g being roughages. Carbohydrates exist naturally or refined as monosaccharides that are reducing sugars. Monosaccharides build the complex carbohydrates, disaccharides and polysaccharides through dehydration synthesis. Monosaccharides have general formula (CH2O)n where ‘n’ determines whether pentose(5Carbons) or hexose (6Carbons). Glucose found in maple syrup, fructose in corn syrup and galactose in honey are hexose-isomers; having the same formula, C6H12O6 but different structures. The disaccharides with the general formula C12H22O11 are sucrose made from fructose and glucose, maltose from two glucose molecules and lactose from galactose and glucose. Sucrose is derived from beet sugar, lactose from milk and maltose from vinegar. The polysaccharides with general formula (C6H10O5)n where 40≠¤n≠¤3000, exist as starch or non-starch polysaccharides (NSPs) which can be soluble or insoluble. Starch consists of glucose molecules joined by glycosidic bonds. The NSPs include oligosaccharide (raffinose) and cellulose (dietary fibre). Potatoes, yams and cassava are rich in starch and are very digestible. Whole grain cereals, legumes (appendix2), fruits and storage vegetables like asparagus and cabbage are rich in the NSPs. Raffinose is an indigestible trisaccharide of fructose,glucose and galactose with formula C18H32O16. Animal sources of carbohydrates are liver and scallops. Carbohydrates provide sweetness and are the primary source of energy especially for brain and blood cells. Cellular respiration converts glucose monomers into ATP. Fats cannot be oxidised without glucose. Most NSPs are partially digestible or indigestible due to lack of ÃŽ ±-galactosidae (enzyme) in GI Tract. They reduce glycaemia index and plasma cholesterol levels, increase bile acid excretion, promote normal laxation and prevent breast cancer, gallstones, haemorrhoids, and irritable bowel syndrome (Kumar et all 2012). Furthermore, Kumar (2012) concluded that excessive carbohydrates will cause dental decay, kidney damage, stroke, diabetes due to obesity and short term conditions like hyperglycaemia. Carbohydrate deficiency will cause constipation, fatigue, weak immunity, muscle cramps and ketosis; this is very rare as 50g/day of carbohydrate is needed to prevent ketosis. THE DEHYDRATION SYNTHESIS TO FORM MALTOSE [pic]Figure2 EQUATION: (C6H12O6 + C6H12O6 = C12H22O11 + H2O) (Marshall University 2012) Proteins or polypeptides consist of three to 100000 or more long chains of the organic molecules called amino acids joined together by covalent peptide bonds. A protein of two amino acids is called a dipeptide. There are 20 common forms of amino acids either termed non-essential (synthesised by the liver) and essential that needs to be ingested. Proteins consist of a central carbon atom, a hydrogen atom, amino group (-NH2), Carboxylic group (-COOH) and the variable R group (figure3). The term amino acid is derived from the amino and carboxylic groups that all amino acids have in common. According Kuil (2012), principal sources of proteins are lean meat, seafood, poultry, eggs, cereals, legumes (refer to appendix3), cereals and processed food like low-fat milk. Proteins form about 45% of human body and perform the following seven essential functions: structural (hair, ligaments), contractile (muscles), transport (haemoglobin), metabolic regulation (enzymes), buffering, defence (antibodies) and coordination and control (hormones) (Martini 2006). Haemoglobin transports oxygen and a lack of protein (haemoglobin) can deny vital organs the needed oxygen for metabolism. Protein deficiency can also cause fatigue, anaemia, weak immunity, skin problems, impairment of cognition and mental health problems. Whereas excessive proteins can cause obesity, osteoporosis and kidney stones (Georgetown University 2012). About 15% of an adults’ caloric intake should come from protein equivalent to 56g and 46g for male and female respectively (Centre for Diseases Control and Prevention, 2012). DEHYDRATION OF AMINO ACIDS TO FORM DIPEPTIDE PROTEINS [pic]Figure3 (Marshall University 2012) Lipids are made up of an even number of carbon from 12 to 20, oxygen, hydrogen and sometimes traces of phosphorus, sulphur or nitrogen. Lipids are grouped into 4: steroids, phospholipids, waxes and glycerides. Most of the 70 identified lipids are synthesised by the body whereas linoleic (omega6) and alpha-linolenic (omega3) acids are two essential lipids to be ingested. They are mostly insoluble due to the long chain of hydrophobic carbon-carbon end bonded to a short hydrophilic carboxyl group. The double covalent bond, (C=C) determines whether saturated (no C=C) or monounsaturated (1 C=C) or polyunsaturated (2 or more C=C). Glycerides are made up of glycerol bonded to 1 or more fatty acids by dehydration synthesis, triglyceride with 3 fatty acids is the predominant of the lipids (refer figure4). Unsaturated sources of lipids are olive oil, peanut, salmon, halibut and avocados. Saturated sources are butter, sausage and hydrogenated oil. According to British Dietetic Association (2013), adults should consume not more than 20-30g of saturated-fat with 5g or less being trans-fat since saturated lipids are high in cholesterol. The structural lipids form cell membranes. Also fat cushions and protects organs including liver, heart, and kidney, energy source; twice as much as carbohydrates and proteins, thermoregulation (insulation), sex hormones, transport vitamins and monounsaturated fat can decrease cholesterol levels (USA Department of Agriculture, 2010). Excessive consumption of lipids will lead to obesity which is characterised by high BMI as shown in appendix 2, cardiovascular diseases, hypertension, colorectal cancer and diabetes, whereas deficiency will result in the body lacking the vital vitamins A,D,E and K (Schenker, 2012). DEHYDRATION SYNTHESIS TO FORM TRIGLYCERIDE [pic]Figure4 (Marshall University 2012) The micronutrients, vitamins and minerals are needed in minute quantities. Minerals can be classified as major or trace of which a few are essential including sodium, potassium, magnesium, zinc, iron, calcium, iodine, etc. (refer to appendix4 for RDAs). According to Higdon and Drake (2011), sources of minerals are plants that derive them from the soil and move on the food chain to the herbivores like cattle that eat them. Spinach, legumes, whole grains, dairy products, red meat, soybeans, salmon, cod, iodised table salt (iodine, sodium, chlorine) and eggs are excellent sources of minerals. According to Whitley and Rolfes (2011), minerals perform the following functions: the electrolytes, sodium, potassium and chlorine transmit nerve impulses, control fluid balance (providing optimum pH for enzyme activities), control blood pressure and relax and contract muscles. Zinc, copper and selenium are antioxidants; they reduce the risk of heart diseases. Iron forms haemoglobin. Sodium and potassium coregulate ATP production. Calcium and phosphorus control blood clotting and together with magnesium build bones, teeth, maintain muscle and nerve cells. Iodine is needed for the production of thyroxin; deficiency will cause goitre. Since some minerals are coenzymes, deficiency will cause malfunctioning cellular activities (digestion, metabolism). Iron deficiency causes anaemia whereas calcium, phosphorus and magnesium (hypocalcaemia) deficiency will cause osteoporosis. Calcium, magnesium and the electrolytes deficiencies will cause weakness, muscle cramps and impaired alertness. Zinc deficiency causes diarrhoea, skin and prostate cancers. Their intake should be balanced with use and excretion as excess may cause Hyperkalaemia (potassium), kidney-stones (calcium) and hypernatremia (sodium). Vitamins are grouped into water soluble (WSV) including C and B complex vitamins; they cannot be stored and therefore, it is imperative to be part of a balanced diet, and fat soluble (FS) including vitamins K,E,D, and A; they can be stored (refer appendix 5 for RDA). Green leafy vegetables (lettuce), oranges, kiwi fruit, avocados, whole grains and cereals, banana, dairy products, liver, poultry, pork, oily fish, eggs, soybeans, chickpeas and nuts are excellent sources of the vitamins (Firth 2011). Vitamin K can be synthesised in the intestine which helps the blood clot whereas Vitamin D can be synthesised by the body using sunlight to help the absorption of calcium and phosphorus (Cranney et al (2010). Vitamins A and C build immunity. Vitamins B1,B2,B3, and biotin help release energy. Vitamin A, niacin and pantothenic acid aid the absorption and use of macronutrients monomers. Vitamin C makes collagen and enhances folate absorption. Vitamin deficiency generally causes weak immunity and osteoporosis (Vitamin D), scurvy (Vitamin C), beriberi (B1), anaemia (B12 and folate) and night blindness (Vitamin A). Excessive amounts of vitamins E and K are usually not harmful but excess A,D and the WSV which can be excreted cause kidney problems and hypercalcaemia (excess D). Excessive vitamin C causes diarrhoea (NHS 2012). In conclusion, spending excessively on supplements and creams as well as engaging in dangerous diets like the Atkins Diet are not necessary. The secret to healthy living is carefully selecting the right proportions of food from the Eatwell plate, drinking enough water in combination with regular exercises. Figure 5 and appendix 6 show functions of water. Consider the positives and negatives when selecting food products such as red meat; rich in protein but high in cholesterol whereas fatty fish enhances calcium absorption. Soybean, liver, green leafy vegetables, whole grains and legumes will provide almost all the nutrients; combine them in your diet in right proportions for optimal hormonal, metabolic, mental and physical functions of the body. It is important to consult a doctor before starting any diet as nutritional needs are affected by health and some medications affect absorption of nutrients.

Navigational Tools :: Websites Internet Technology Computers Essays

Navigational Tools When designing a website, a web designer must develop and create an effective way of navigating his or her website. When doing this job, the web designer must keep the principle of compensation in mind. According to authors Killingsworth and Gilbertson â€Å"in every revision of a text, something is lost and something is gained† (45). Using this principle of compensation, a web designer must realize the consequences for choosing a picture, icon, or text to represent links on his or her web page. For each one there are advantages and drawbacks, which if weighed or balanced properly can enhance that web designer’s page. Human beings by nature are visually oriented; therefore, the web designer should find a satisfactory medium between the use and placement of either text or graphics. According to Brad Bachetti in his response â€Å"Creating a Roadmap†, â€Å" If both text and graphics are used to represent the button, it is visually appealing to keep the text and g raphics of equal width. This is exemplified on the main page of the WebCT course page† (Bachetti). If we take a look at the WebCT course page, we will find this to be true. The WebCT course page also exemplifies the principle of compensation. The pictures that accompany the text not only compliment each other in width and size, but also enhance each other. Together the pictures and text convey better meaning then they would if they stood alone, thus allowing for easy navigation on the course page. Sometimes though a web designer may only want to use a picture, icon, or text to represent a link or navigational tool on a website. According to Principles of Web Design, by David and Jean Farkas, â€Å"Links must make clear their destinations the page that the link will display† (209). Using this simple principle put forth by the authors, a web designer may encounter problems when dealing with pictures and icons to represent links or navigational tools. According to Farkas, â€Å"to design links that will communicate their destination clearly, you need to think about your audience and their information needs† (Farkas 209). A picture and icon may have different connative or denotative meanings for people of a different age, gender, race, or nationality. That being stated icons and pictures have some significant advantages over text links. For example, a familiar one is processed faster, icons communicate across languages and cultures, they are visually interesting, and they often save space (Farkas 211).
