Identification of food constituents in milk Essay

Objective †¢To look at and investigation the sythesis of two unique kinds of obscure milk, K1 and K2. †¢To decide the distinctions of the fat substance in milk tests, K1 and K2. †¢To look at the lessening sugar in the two examples of milk, K1 and K2. †¢To think about the protein fixations in the two examples of milk, K1 and K2. Presentation Milk gives a valuable dietary wellspring of calcium, which is fundamental for the development and upkeep of bone and tooth. Milk is the principal wellspring of sustenance as it assumed a significant job in human nourishment. The constituents in milk that are imperative in food readiness are compounds, nutrients, colors, salts, sugar, fat, and proteins. Distinctive milk tests which contain diverse food constituents will have an alternate dietary benefit separately. Sudan (III) is fat-solvent color utilized for recoloring of triglycerides (fat). It is utilized in the analysis to distinguish for the nearness of unsaturated fats. It will show up as red globules if unsaturated fats are available in the milk test. Benedict’s reagent is utilized to test for the nearness of lessening sugars. The arrangement will frame a block red encourage when the milk test contains decreasing sugar (glucose, maltose, lactose.) Sugar that can shape an aldehyde and ketone within the sight of a soluble arrangement is known as lessening sugars. The Biuret test is utilized to test for the nearness of protein. The biuret test depends on the capacity of Cu (II) particles to frame a violet-hued chelate complex with peptide bonds (- CONH-gatherings) in basic conditions. In Biuret’s test (comprise of sodium hydroxide and copper (II) sulfate solution),the arrangement will go to purple when the proteins are available in the milk test. Proteins are natural mixes significant for development and fix. Protein particles are made principally out of amino acids connected together through peptide bonds. Materials Copper(II) sulfate arrangement, obscure milk test (K1,K2), cooking oil, refined water, serving of mixed greens oil, Sudan(III), full cream milk, Benedict reagent, 10% potassium hydroxide, 0.5% copper(II) sulfate Device Test tubes, plastic pipettes, plug, water shower Techniques (A) 1. A spotless test tube is filled until 1cm of the top with copper (II) sulfate arrangement. 2. A limited quantity of K1 is pipette into a spotless plastic pipette and a drop is tenderly discharged into the copper (II) sulfate arrangement as appeared in Figure 3. Another drop of milk is additionally discharged. 3. At that point the pipette is pulled back gradually without upsetting the copper (II) sulfate arrangement. The development of K1 is watched cautiously and the perceptions are noted. 4. The methodology above is continued utilizing new, new copper (II) sulfate arrangement, new clean glass contraption and the example of K2. Perceptions on the development of K2 are recorded and any distinctions in the conduct of the drops of K1 and K2 are noted cautiously. (B) 1. 6 test tubes are acquired and numbered them from 1-6. 2.

Sudan III in this examination is utilized for recoloring lipids or fats. Sudan colors are a gathering of lipid dissolvable colors called lysochromes. Sudan III additionally used to shading the protein bound lipids in paraffin segments. 2.Which test tube is i.Positive control? Test tube 1, 2, 3, 5, and 6 are certain control. ii.Negative control? Test tube 4 was negative control. 3.Describe the science of fluid test utilizing Sudan III. Sudan III is utilized to decide the nearness of lipids. It will recolor the fat cells red. Sudan III is generally utilizing in lipid test. To start with, the fluid being test and water are filled to a test tube about half full. 3 drops of Sudan III are added to test tube and being shaken delicately. There will shape a red-recolored oil layer separate out and coast on the water surface because of the nearness of fat. C.(i) Reducing sugar test Kinds of obscure milkObservation K1Orange accelerate is shaped. K2Yellow-orange arrangement is shaped. (ii) Protein test Kinds of obscure milkObservation K12 layers arrangement of darker marginally purple smooth arrangement and white shading milk is shaped. K2Slightly purple smooth arrangement is framed. Conversation In the section An examination, milk beads of K1 and K2 are discharged into the copper (II) sulfate arrangement tenderly. After discharged, both of the beads are not broken up in it. The K1 bead gradually sank in the copper (II) sulfate arrangement while K2 bead gradually glided on the highest point of copper (II) sulfate arrangement because of the distinctive thickness. The thickness of K1 was higher than the thickness of K2 and copper (II) sulfate arrangement while K2 was lower thickness than CuSO4 arrangement. This investigation is utilized to decide the fat contained in various sorts of milk by the development of milk beads in CuSO4 arrangement. The higher the thickness of milk, the lower the fat contained. The outcomes demonstrated that K1 contained less fat contrasted with K2. In this manner, K1 was low-fat milk while K2 was full cream milk. In the part B try, cooking oil, serving of mixed greens oil, full cream milk, and refined water were blended in with Sudan III in various t est tubes for deciding the lipid. Lipids are insoluble in polar solvents for instance water and can break down in non-polar dissolvable. Lipids are less thick than water and will skim on the outside of arrangement. Sudan III in this test was utilized to shading the lipids. It recolored the fat cells to become red shading. On the off chance that lipid was introduced, Sudan III will recolor it and structure red-recolored oil. In test tube 1, cooking oil drifted on the water surface in the wake of being shaken. In test tube 2, marginally red arrangement being seen after shaken demonstrated that serving of mixed greens oil contain lipids. In test tube 3, the white shading full cream milk turned out to be somewhat pink smooth arrangement after added with Sudan III because of the fat introduced in it. In test tube 4, refined water framed a straightforward marginally red arrangement after Sudan III was added to it. Sudan III was disintegrated in refined water however water is consistently negative control on the grounds that there are just H2O particles in it. In test tube 5, 3 layers arrangement became 2 layers arrangement that cooking oil at the surface. Oil turned out to be marginally red and Sudan III broke down in oil. Sudan III is substantially more dissolvable in oil than in refined water, so the refined water despite everything clear after test as a result of Sudan III was consumed by the oil. The last test tube which is test tube 6, the perception was like test tube 2 yet it framed marginally orange arrangement which additionally contained lipids. Test tube 1, 2, 3, 5, and 6 recolored red indicated the nearness of fat while test tube 4 was the main example fluid that didn't recolored by Sudan III which fat missing. In diminishing sugar test, Benedict’s reagent was utilized. Tests of milk, K1 and K2 became orange shading arrangement when tried with Benedict’s arrangement and warmed. The perception indicated that there was decreasing sugar introduced in both two milks. The arrangement included with Benedict’s reagent will change shading from green to red rely upon the centralization of sugar gave. Prior to warming, K1 and K2 were somewhat blue smooth arrangement in light of the fact that additional with blue shading Benedict’s arrangement. The shade of the milk changed during warming in the water shower. During the warming segment, both of K1 and K2 were changed to green shading lastly orange shading arrangements were shaped. K1 created darker shade of orange than K2 and hasten framed in K1 indicated that the sugar grouping of K1 was higher than K2. The biuret test depends on the capacity of Cu (II) particles to frame pink or purple colo

Grape Jelly Professor Ramos Blog

Grape Jelly My heart was raising, my cheeks hurt from grinning, and my hands were shaking. My father rang the entryway chime, and we were welcomed by my friend’s mother who grinned and took my blue green hiking bed. My father gave me a major embrace and said â€Å" I’ll see you toward the beginning of the day. Have a decent time.†Ã¢ I than strolled into the greatest kitchen my multi year old self had ever been in. It was one of those kitchens that you see in HGTV appears. It was so perfect, with open cupboards, and presumably the most delightful and greatest refrigerator I had ever observed. Still right up 'til today, similar to 15 years after the fact, the most pleasant kitchen I’ve ever walked in.â My companions were all siting around an enormous round wooden table preparing to eat make your own frozen yogurt desserts. I was so energized on the grounds that this was the first occasion when I had ever gotten the opportunity to make my own frozen yogurt parfait. Fu rthermore, this family utilized the great frozen yogurt. I’m talking like Haagen Dazs, and natural sprinkles, and Ghirardelli Hot Fudge. All the great stuff. I thought I was living in a dream.â At the point when I was in the third grade my family moved from Sacramento to Lake Arrowhead, California. We had lived in a region of Sacramento that was not the most delightful. In any case, my family consistently had what we required. So when I got the news that my family would be moving to Lake Arrowhead it was somewhat of a shock. I didn’t truly know anything about Lake Arrowhead, however it appeared to be path more pleasant than the region where I had known as home for 7 or 8 years. In Sacramento everybody I knew had a similar measure of cash as my family, or less. It was a decent loft neighborhood that my family was separated of. We as a whole had about a similar measure of cash, and I didn’t know any better. The high rise was not known for a ton. I mean the most pleasant piece of the entire zone was the way that the principle grass got watered enough to remain green all through the entire year. Be that as it may, every one of our neighbors were extremely decent, and all that is pretty much all you have to know when your 8 years of age. I realized that there were heaps of individuals who had much more than me, and that there numerous individuals who had significantly short of what me. Yet, I had no clue how considerably less I really had until I begun the third grade at another school in Lake Arrowhead. Growing up my father consistently disclosed to me that the explanation we just had grape jam in our home was on the grounds that it was a poor keeps an eye on jam. This announcement constantly stayed with me, and it never truly accord to me what he implied by that announcement until I was confronted with the frozen yogurt parfait circumstance. To he legit I constantly favored strawberry jam, yet I possibly had it when I was over at my grandparents house. And keeping in mind that this announcement appears to be quite cruel to tell a third grader, it at last showed me one of the best life exercises an individual can learn. At the point when I was a child I believed that it was absolutely ordinary to set aside your jars and bottles and reuse them toward the month's end so as to get an exceptional treat from McDonalds. This was a colossal arrangement for me and my sibling. We cherished getting frozen yogurt with our Dad. We couldn't have cared less whether the frozen yogurt was from Rite Aid or McDonalds, it was only amusing to reuse and utilize that cash to get a virus treat with our Dad. The second I understood that it was not that ordinary of an everyday practice to reuse for cash except if you are destitute, or a broke understudy, was at that first sleepover. The entirety of my companions that I had meet while living in Lake Arrowhead, had frozen yogurt in their home coolers. None of them needed to hold up till the month's end. Nor did they get the chance to pick between Rite Aid or McDonalds. Their folks just purchased frozen yogurt on the customary, similar to it was bread or milk. While we were making our desserts my companions were discussing the cool and fun family experiences they were go to be going on. In any case, everything I could do was simply stay there and tune in. At the point when the gathering moved first floor, we as a whole began to set up our camping cots, and brush our teeth. â€Å"Hey folks lets all sit under the pool table, and discussion about the young men in our class† one of my companions proposed. I had never observed a pool table outside of a film previously, and I thought it was overly cool that this family simply had a pool table that they could play whenever they needed. The house had numerous accounts, and the lower level where we would be dozing was essentially a game room. It had a truly enormous TV, a pool table, and various rooms. This house was gigantic. The kitchen was only the beginning of how stunning this house continue getting. With regards to decent variety the normal individual considers racial imbalance. Be that as it may, decent variety comes in various structures. What's more, in my life assorted variety has come as cash and financial status. Lake Arrowhead isn't the greatest and most extravagant of regions with regards to California guidelines. That being said it is home to numerous people’s summer homes. The entire populace of Lake Arrowhead really develops by about half in the mid year. So you can envision that it was somewhat of a stun to be out of nowhere encircled by such a significant number of individuals who could manage the cost of far beyond me, subsequent to living in a region where it was absolutely worthy to simply play and drink from a similar network hose. So living in an evaluation jam just family, truly makes you a superior individual. I have constantly attempted to remember that express in all circumstances that I happen upon. I realize that assorted variety isn't continually something that you can see when you initially meet somebody. What's more, I believe that it is essential to share these accounts to show that everybody is experiencing or has been experiencing something that only one out of every odd would see all things considered.

Food and Beverage Management Human Resource Management International

Question: Talk about the Food and Beverage Management for Human Resource Management International Digest? Answer: Presentation The investigation would concentrate on recruiting of new Bartender for a bar in particular Luger Sports Bar and Grill in the New York City. Mr. Luger is looking for a Bartender who can work for expanded moves and shutting hours in the bar (Onyema and Ofoegbu 456). He has four candidates to choose from, for procuring the best with the capacity of helping the buyers in a dazzling way. Required Criteria The qualification models for the choice of a barkeep are as per the following: Dire prerequisite for a Bartender with rewarding compensation bundle Age: Minimum 21 or more Sex: Preferably Male Capability: Minimum 12TH pass, Graduates in Hospitality Management Preferable Move Timings: 12pm 11pm ( Extension of Shifts upon necessities) Qualification Criteria: The individual ought to have amazing relational abilities and have a satisfactory demeanor. Experienced up-and-comers are best over the fresher and ought to be able to deal with disorderly circumstance. A person with a cool and cordial demeanor is the best decision for the post. Compensation: 15-21k. Worthwhile motivators are extra Contact Person: Mr. Luger Contact Number: 845******* Setting: Lugers Sports Bar and Grill Determination Procedure In the contemporary situation of café and bar business, recognizing an effective barkeep is much the same as striking gold. Each barkeep has the nature of blending drinks, however every couple of are honored with the committed blend of cordiality and detachedness, which is the trademark for an effective barkeep (Pantelidis and Ioannis pp. 249). Endless supply of a Bartender, the spotter would approach certain inquiries to the candidates for the situation of a barkeep. Rundown of Interview Questions How might you carry on with a person who has taken a lot of beverages? How might you change with the drunker buyers of other gender? What are the qualities of taking care of a bar with a bustling timetable? How might you handle a frustrated customer? How might you handle any disorderly situation? How might you carry on the off chance that you have any issues with some other part? Are your tips confirmed? While choosing a Bartender, Mr. Luger constantly considered checking references before recruiting a barkeep from the blues. The selector ought to have a feeling of carefulness for choosing the most proper barkeep. There is a centrality for experienced Bartenders if the association intends to satisfy the apparent needs and requests of the buyers. While examining the candidate with the inquiries referenced over, the selector will have the option to recognize the charismatic skill abilities of a barkeep, which is the most determinant factor of accomplishment for the association in the serious market (Vai et al. pp. 36). The selector will explore the foundation and notoriety of the candidate for defending the notoriety of the bar. The Bartender will be a decent audience or possibly address to counterfeit tuning in. The selector ought to likewise check the tolerance level of dealing with unfavorable circumstances by asking him inquiries identified with entangled situation in a bar (Anders pp. 780). Upon effective cross examination with the candidate, the select should check the reality whether the candidate has any criminal record (Valta and Katerina pp. 3347). These are the essential regions of prerequisite for appropriation of a fruitful barkeep. Endless supply of the needful standards, the enrollment specialist chose Allison for the post of a barkeep at Luger Sports Bar and Grill. Avocation of Selection The selector has settled on Allison dependent on his qualification and tremendous involvement with the accommodation division. The accompanying table will exhibit the explanation of choosing Allison over Megan, Scott and John. Candidate Name Purposes for Selection and Rejection John John has met certain prerequisites of the qualification rules, in any case, one of the significant purposes behind not choosing John, is his crankiness, which doesn't satisfy the essential necessity of a fruitful barkeep. For instance, a heart broken sweetheart or a divorced person may disturb a barkeep by pouring his/her heart loaded down with distress. If there should be an occurrence of such circumstances, the barkeep ought to be a decent audience, rather than being getting disturbed at normal interims. Besides, John has next to zero involvement in blending drinks, which again add to the needful properties of a barkeep. Scott Scott has all the qualification of a triumph barkeep yet when contrasted with that of Allison, the last takes the edge over Scott due his neighborliness degree and confirmation course in alcohols spirits and wines. In this way, Allison will in general be the best fit for the bar of Mr. Luger Megan One of the significant hindrances for not picking Megan is her naiveté for the post of a barkeep. Besides being a female it represents the two points of interest and impediments corresponding to the achievement factor of business acquisitions. On one hand, being a female, it can end up being a potential risk for ladies while working for expanded shifts, yet at the same time it could end up being a surprisingly beneficial development for the bar as female are generally acquainted with agreeable acquisitions and drawing in shoppers. Allison Allison has all the segments of turning into an effective barkeep for the bar of Mr. Luger. He is a lot of informative, have immense experience of blending drinks and a degree holder of accommodation the executives. Notwithstanding that, he exceeds expectations in his obtaining of an endorsement course in alcohols, spirits and wines. He is the best fit for the post as he satisfies all the above qualification referenced in the measure list. He has the ability of guessing singular thoughts and associates with the buyers, in this way contributing towards authoritative accomplishment in the serious market. End In actuality, it infers that, Mr. Luger can be fulfilled while choosing Allison for the post of barkeep on Lugar Sports Bar and Grill. Allison isn't just a decent audience, however he has additionally aced the specialty of phony tuning in. An individual who as of late said a final farewell to his accomplice will require an ear for spilling his distress out in a powerful way. In this situation, the relational abilities of Allison can appear. His record of achievement recommends that he is a legit and reliable worker for the bar. His persuasiveness aptitudes are exemplary ordinarily and his experience will contribute towards authoritative achievement in the completive market. Reference Anders, G.

Lung Cancer Essay - 1100 Words

Lung Cancer Essay (Case Study Sample) Content: NameStudent IDInstructorDateLung cancer develops from mutation of epithelial cells lining the bronchi, bronchioles and the alveoli. Carcinogens attack the cell DNA triggering mutation of epithelial cells. Mutation of the cells triggers oncogenes, reduce tumor-suppressing factors or delete short arm chromosome 3(Braun Anderson, 2012). This damage eventually generates cellular changes and abnormal cell growth resulting in a malignant cell. During cell division, the DNA changes move to daughter cells where they undergo further changes resulting in unstable cells and eventually a carcinoma (smeltzer, Bare, Hinkle, Cheever, 2010). Exposure of lung epithelial cells to uranium triggered the process of carcinogenesis that occurs in three stages: initiation, promotion and progression (Penning, 2011).Initiation is the first stage of carcinogenesis that involves the exposure of normal epithelial cells to carcinogens. The carcinogens interact with the cell DNA disrupting the ge netic programming of the relevant cell (Weinberg, 2013). Various possible results may occur. The cell may; remain in non-dividing state, become non-responsive to tumor suppressing factors, undergo programmed cell death or undergo abnormal cell division. If the cell divides without the repair of DNA disruption, the change in genetic coding remains permanent (Penning, 2011). At this stage, the initiated cells can remain latent for years or weeks or grow in an independent and clonal design. Cell division remains symmetrical through the action two processes mitosis and apoptosis inhibition (Penning, 2011). Mitosis causes an increase in the number of mutated cells while apoptosis inhibition prevents the death of mutated cells. Initiation is a fast and irreversible process, which transfers to daughter cells (Weinberg, 2013). The initiated cells then move to the second phase in the carcinogenesis model, promotion. Promotion involves an accelerated rate of proliferation of the initiated cel ls resulting in the development of a neoplasm. This stage involves the action of tumor promoters, which induce cell proliferation without necessarily interacting with the cells DNA (Penning, 2011). This process therefore is reversible through the inhibition tumor promoting factors. On the other hand, tumor promoters can indirectly damage the cell through oxidation (Weinberg, 2013). For effective results, the tumor promoting factors ought to be of high concentration and present in the target cells for sufficient time. The tumor promoters are effective only to initiate cells (Penning, 2011). The increasing neoplasm is vulnerable to further genetic modification predisposing the patient to genetic and epigenetic changes in cancer genes and the development of metastatic cancer (Weinberg, 2013).Progression is the final stage in the carcinogenesis model. The phase involves genomic instability and amplification, alteration of chromosomal structure and number and disrupted gene expression (P enning, 2011). There is non-stimulated cell proliferation. In addition, irreversible morphological and biochemical changes to the cells cause rapid cell growth and metastasis of the neoplasm. Angiogenesis that occurs during epigenetic modification facilitates malignancy, which occurs in this phase (Penning, 2011). Cachexia in cancer patients is a due to altered metabolism of fats, carbohydrates, protein and anorexia that restricts dietary intake (Seyfried, Cancer as a Metabolic Disease, 2012). The process is complex and involves the action of two factors: host factors like interleukins (IL-1 IL-6), interferon gamma, leukemia inhibitory factors, tumor necrosis factors and tumor products that cause catabolism of body tissues. Interleukins (IL-1), tumor necrosis factor (TNF) suppress lipoprotein lipase and promote the intracellular breakdown of lipids. Interleukins (IL-1) trigger anorexia that reduce caloric intake (Allegra, 2015). Interferon gamma and tumor necrosis factor cause an increase in the rate of glycerol and free fatty acid turnover (Seyfried, Cancer as a Metabolic Disease, 2012). Reduced caloric intake due to anorexia leads to hypoglycemia. Demand for source of energy by the brain cells leads to increased breakdown of glycerol and fatty acids in the liver to generate ketone bodies, an alternative source of energy to the brain (Allegra, 2015). Increased rate of lipolysis and reduced rate of lipogenesis lead to loss of adipose tissue with resultant cachexia(Seyfried, Cancer as a Metabolic Disease, 2012). Interleukin (IL-6 and IL-8), proteolysis inducing factor (PIF) and tumor necrosis factors triggers an acute phase response (APR) (Seyfried, Cancer as a Metabolic Disease, 2012). During this phase, the function of the liver shifts from the synthesis of albumin to the production of C-reactive protein, serum amyloid-A protein and beta two macroglobulin. At the same time, proteolysis inducing factor and tumor necrosis factor trigger the proteolytic pathw ay (Seyfried, Cancer as a Metabolic Disease, 2012). The rate of intracellular protein breakdown increases while that of protein synthesis decreases. The expression of uncoupling protein 3 in skeletal muscle cells also increases, increasing their metabolic demands (Allegra, 2015). These mechanisms eventually result in significant loss of muscle mass.Nevertheless, the resting energy expenditure (REE) in patients with lung cancer increases (Allegra, 2015). This is due to the effects of uncoupling protein 3 on mitochondrial RNA (mRNA). Increased production of systemic inflammatory mediators and acute proteins further increase the resting energy expenditure (Seyfried, Cancer as a Metabolic Disease, 2012).Moreover, the high rate of cell division during carcinogenesis increases the basal metabolic rate and thus demand for glucose (Allegra, 2015). However, the dietary source of glucose in these patients is impaired due to anorexia. Besides, the neoplasm predominantly consumes glucose gener ated through gluconeogenesis and oxidative phosphorylation (Allegra, 2015). There are diminished energy reserves for the patient causing loss of strength and general body weakness (Allegra, 2015). Small cell lung cancer causes paraneoplastic neurologic disorders, which manifest with impaired cerebral function (Seyfried, Cancer as a Metabolic Disease, 2012). Paraneoplastic cerebellar and autonomic degeneration is the most common disorder and causes abnormal muscle function (Seyfried, Cancer as a Metabolic Disease, 2012). Cancerous cells express intracellular onconeural antigens that trigger the bodys im...

Natural Polymers and Their Delivery Applications - 275 Words

Natural Polymers and Their Delivery Applications (Essay Sample) Content: Natural polymers and their delivery applicationsAuthor:Institution:Natural Polymers and their delivery applicationsIn recent years there have been vital developments in pharmaceutics of designed drugs. Mucilage and gums are widely used natural materials for novel and conventional dosage forms. Their advantages over synthetic ones being that, they are chemically stable, safe, cheaper, widely available and biodegradable. They can also be modified in different ways to obtain tailor-made materials for drug delivery systems. (Reis, Neves Institute of Materials, Minerals, and Mining 2008).Various polymers are useful as drug retarding agents. Characteristically, hydrophilic polymers are the most suitable for retarding drug release and there is great possibility of using these polymers in sustained drug delivery. This paper mentions some plant-derived polymers, used as release retardant in sustained or controlled release drug delivery systems. (Reis, Neves Institute of Mate rials, Minerals, and Mining 2008).The common natural polymers include carrageenan 2, chitosan 1, acacia; ispaghula, gelatin, agar, guar gum, shellac gum and karaya 3.These are widely applied as adjuvant, adhesives, emulsifying agents, in matrix controlled system. They are also used as film coating agents, vehicles in viscous liquid preparations like oral solutions, viscosity modifiers, tablet disintegrants, surfactants, gelling agents, suspending agents, bio-adhesives, binders, stabilizers as well as solubilizers.Sustained drug delivery systems have adequately improved the drug delivery in terms of efficacy. Drug-release-retarding polymers are vital in the sustained release drug delivery system. Besides, some polymers are used in novel drug delivery systems design like the region-specific ones, which can target the gastrointestinal system. (Jenkins Institute of Materials, Minerals, and Mining, 2007).In conclusion, we see natural polymers like gelatin, being applied widely as therap eutic drug carriers. The efficiency of delivery as well as release of active ingredient is influenced by, drug loading, polymer type, particle size, molecular weight, drug-polymer int...

The Odyssey Themes Of Loyalty, Justice, And Hospitality

As children, humans are taught to analyze. They are taught to look at a piece of information and find a deeper meaning within it. Students analyze statistics, body language, beliefs, and works of literature. When teachers teach about analyzation within works of literature, most attempt to have a student find a theme, or what the author is trying to teach the reader. While some books only have one themes, others have a multiple. In one of Homer s most famous pieces of literature, various themes can be found. Throughout The Odyssey, three major themes of loyalty, justice, and hospitality are present. Loyalty is a basic human virtue that is glaringly visible in this book. First of all, Odysseus crew is aggressively loyal to him. The book starts off with Odysseus just finishing the Trojan War. His crew went through the war lasting a decade with the hero and never once left his side. All of his men were willing to go to take their lives for Odysseus, which is the ultimate form of loyalt y. Odysseus wife, Penelopeia’s emotions show immense loyalty towards Odysseus as well. She has over 100 suitors vying for her hand in marriage and tries to delay picking one as long as possible. Penelopeia creates a intricate scheme to hold them off.

The Triassic, Jurassic, and Cretaceous Periods

The Triassic, Jurassic, and Cretaceous periods were marked out by geologists to distinguish among various types of geologic strata (chalk, limestone, etc.) laid down tens of millions of years ago. Since dinosaur fossils are usually found embedded in rock, paleontologists associate dinosaurs with the geologic period in which they lived—for example, the sauropods of the late Jurassic. To put these geologic periods in the proper context, bear in mind that the Triassic, Jurassic,  and Cretaceous dont cover all of prehistory, not by a long shot. First came the Precambrian period, which stretched from the earth’s formation to about 542 million years ago. The development of multicellular life ushered in the Paleozoic Era (542–250 million years ago), which embraced shorter geologic periods including (in order) the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian periods. Its only after all that that we reach the Mesozoic Era (250-65 million years ago), which includes the Triassic, Jurassic and Cretaceous periods. Ages of the Dinosaurs (The Mesozoic Era) This chart is a simple overview of the Triassic, Jurassic, and Cretaceous periods, all of which were part of the Mesozoic era. In brief, this incredibly long period of time, measured in mya or millions of years ago, saw the development of dinosaurs, marine reptiles, fish, mammals, flying animals including pterosaurs and birds, and a huge range of plant life. The largest dinosaurs did not emerge until the Cretaceous period, which started over 100 million years after the start of the age of dinosaurs.

In terms of animal life, the Triassic was most notable for the diversification of archosaurs into pterosaurs, crocodiles, and the earliest dinosaurs, as well as the evolution of therapsids into the first true mammals. Climate and Geography During the Triassic Period   During the Triassic period, all of the Earths continents were joined together into a vast, north-south landmass called Pangaea (which was itself surrounded by the enormous ocean Panthalassa). There were no polar ice caps, and the climate at the equator was hot and dry, punctuated by violent monsoons. Some estimates put the average air temperature across most of the continent at well above 100 degrees Fahrenheit. Conditions were wetter in the north (the part of Pangaea corresponding to modern-day Eurasia) and the south (Australia and Antarctica). Terrestrial Life During the Triassic Period The preceding Permian period was dominated by amphibians, but the Triassic marked the rise of the reptiles—notably the archosaurs (ruling lizards) and therapsids (mammal-like reptiles). For reasons that are still unclear, the archosaurs held the evolutionary edge, muscling out their mammal-like cousins and evolving by the middle Triassic into the  first true dinosaurs  like  Eoraptor  and  Herrerasaurus. Some archosaurs, however, went in a different direction, branching out to become the first pterosaurs ( Eudimorphodon  being a good example) and a wide variety of  ancestral crocodiles , some of them two-legged vegetarians. Therapsids, in the meantime, gradually shrank in size. The  first mammals  of the late Triassic period were represented by small, mouse-sized creatures like Eozostrodon and Sinoconodon. Marine Life During the Triassic Period Because the Permian Extinction depopulated the worlds oceans, the Triassic period was ripe for the rise of early marine reptiles. These included not only unclassifiable, one-off genera like Placodus and  Nothosaurus  but the very first  plesiosaurs  and a flourishing breed of fish lizards, the ichthyosaurs. (Some ichthyosaurs attained truly gigantic sizes; for example,  Shonisaurus  measured 50 feet long and weighed in the vicinity of 30 tons!) The vast  Panthalassan  Ocean soon found itself restocked with new species of  prehistoric fish, as well as simple animals like corals and cephalopods. Plant Life During the Triassic Period The Triassic period wasnt nearly as lush and green as the later Jurassic and Cretaceous periods, but it did see an explosion of various land-dwelling plants, including cycads, ferns, Gingko-like trees, and seed plants. Part of the reason there were no plus-sized Triassic herbivores (along the lines of the much later  Brachiosaurus) is that there simply wasn’t enough vegetation to nourish their growth. The Triassic/Jurassic Extinction Event Not the most well-known extinction event, the Triassic/Jurassic extinction  was a fizzle compared to the earlier Permian/Triassic extinction and the later  Cretaceous/Tertiary (K/T)  extinction. The event, nevertheless, witnessed the demise of various genera of marine reptiles, as well as large amphibians and certain branches of archosaurs. We dont know for sure, but this extinction may have been caused by volcanic eruptions, a global cooling trend, a meteor impact, or some combination thereof.   The Jurassic Period Thanks to the movie  Jurassic Park, people identify the Jurassic period, more than any other geological time span, with the age of dinosaurs. The Jurassic is when the first gigantic sauropod and theropod dinosaurs appeared on Earth, a far cry from their slender, man-sized ancestors of the preceding Triassic period. But the fact is that dinosaur diversity reached its peak in the ensuing  Cretaceous  period. Geography and Climate During the Jurrasic Period   The Jurassic period witnessed the breakup of the Pangaean supercontinent into two big pieces, Gondwana in the south (corresponding to modern-day Africa, South America, Australia, and Antarctica) and  Laurasia  in the north (Eurasia and North America). At about the same time, intra-continental lakes and rivers formed that opened new evolutionary niches for aquatic and terrestrial life. The climate was hot and humid, with steady rainfall, ideal conditions for the explosive spread of lush, green plants. Terrestrial Life During the Jurassic Period Dinosaurs:  During the Jurassic period, relatives of the small, quadrupedal, plant-eating  prosauropods  of the Triassic period gradually evolved into multi-ton  sauropods  like  Brachiosaurus  and  Diplodocus. This period also saw the concurrent rise of medium- to large-sized  theropod  dinosaurs like  Allosaurus  and  Megalosaurus. This helps explain the evolution of the earliest, armor-bearing  ankylosaurs  and stegosaurs. Mammals:  The mouse-sized  early mammals  of the Jurassic period, only recently evolved from their Triassic ancestors, kept a low profile, scurrying around at night or nesting high up in trees so as not to get squashed under the feet of bigger dinosaurs. Elsewhere, the first feathered dinosaurs began to appear, typified by the extremely bird-like   Archaeopteryx  and  Epidendrosaurus. Its possible that the first true  prehistoric birds  had evolved by the end of the Jurassic period, though the evidence is still sparse. Most paleontologists believe that modern birds descend from the small, feathered theropods of the Cretaceous period. Marine Life During the Jurassic Period Just as dinosaurs grew to bigger and bigger sizes on land, so the  marine reptiles  of the Jurassic period gradually attained shark- (or even whale-) sized proportions. The Jurassic seas were filled with fierce  pliosaurs  like  Liopleurodon  and Cryptoclidus, as well as sleeker, less frightening plesiosaurs like   Elasmosaurus. Ichthyosaurs, which dominated the Triassic period, had already begun their decline.  Prehistoric fish  were abundant, as were squids and  sharks, providing a steady source of nourishment for these and other marine reptiles. Avian Life During the Jurassic Period By the end of the Jurassic period, 150 million years ago, the skies were filled with relatively advanced  pterosaurs  like  Pterodactylus,  Pteranodon, and  Dimorphodon. Prehistoric birds  had yet to fully evolve, leaving the skies firmly under the sway of these avian reptiles (with the exception of some prehistoric insects). Plant Life During the Jurassic Period Gigantic plant-eating sauropods like  Barosaurus  and  Apatosaurus  couldn’t have evolved if they didn’t have a reliable source of food. In fact, the landmasses of the Jurassic period were blanketed with thick, tasty coats of vegetation, including ferns, conifers, cycads, club mosses, and horsetails. Flowering plants continued their slow and steady evolution, culminating in the explosion that helped fuel dinosaur diversity during the ensuing Cretaceous period. The Cretaceous Period The Cretaceous period is when dinosaurs attained their maximum diversity, as  ornithischian  and  saurischian  families branched off into a bewildering array of armored, raptor-clawed, thick-skulled, and/or long-toothed and long-tailed meat- and plant-eaters. The longest period of the Mesozoic Era, it was also during the Cretaceous that the Earth began to assume something resembling its modern form. At that time,   life was dominated not by mammals but by terrestrial, marine and avian reptiles. Geography and Climate During the Cretaceous Period During the early Cretaceous period, the inexorable breakup of the Pangaean supercontinent continued, with the first outlines of modern North and South America, Europe, Asia and Africa taking shape. North America was bisected by the Western Interior Sea (which has yielded countless fossils of marine reptiles), and India was a giant, floating island in the Tethys Ocean. Conditions were generally as hot and muggy as in the preceding  Jurassic  period, albeit with intervals of cooling. The era also saw rising sea levels and the spread of endless swamps—yet another ecological niche in which dinosaurs (and other prehistoric animals) could prosper. Terrestrial Life During the Cretaceous Period Dinosaurs:  Dinosaurs really came into their own during the Cretaceous Period. Over the course of 80 million years, thousands of meat-eating genera roamed the slowly separating continents. These included  raptors,  tyrannosaurs  and other varieties of theropods, including the fleet-footed  ornithomimids  (bird mimics), the strange, feathered  therizinosaurs, and an uncountable profusion of small,  feathered dinosaurs, among them the uncommonly intelligent  Troodon. The classic herbivorous sauropods  of the Jurassic period had pretty much died out, but their descendants, the lightly armored titanosaurs, spread to every continent on earth and attained even more massive sizes.   Ceratopsians  (horned, frilled dinosaurs) like  Styracosaurus and  Triceratops  became abundant, as did  hadrosaurs  (duck-billed dinosaurs), which were especially common at this time, roaming the plains of North America and Eurasia in vast herds. Among the last dinosaurs standing by the time of the K/T Extinction were the plant-eating  ankylosaurs  and  pachycephalosaurs  (thick-headed lizards). Mammals:  During most of the Mesozoic Era, including the Cretaceous period, mammals were sufficiently intimidated by their dinosaur cousins that they spent most of their time high up in trees or huddling together in underground burrows. Even so, some mammals had enough breathing room, ecologically speaking, to allow them to evolve to respectable sizes. One example was the 20-pound Repenomamus, which actually ate baby dinosaurs. Marine Life During the Cretaceous Period Shortly after the beginning of the Cretaceous period, the  ichthyosaurs  (fish lizards) disappeared.   They were replaced by vicious  mosasaurs, gigantic  pliosaurs  like  Kronosaurus, and slightly smaller  plesiosaurs  like  Elasmosaurus. A new breed of bony  fish, known as teleosts, roamed the seas in enormous schools. Finally, there was a wide assortment of  ancestral sharks; both fish and sharks would benefit immensely from the extinction of their marine reptile antagonists. Avian Life During the Cretaceous Period By the end of the Cretaceous period,  pterosaurs  (flying reptiles) had finally attained the enormous sizes of their cousins on land and in the sea, the 35-foot-wingspan  Quetzalcoatlus  being the most spectacular example. This was the pterosaurs last gasp, though, as they were gradually replaced by the first true  prehistoric birds. These early birds evolved from land-dwelling feathered dinosaurs, not pterosaurs, and were better adapted for changing climatic conditions. Plant Life During the Cretaceous Period As far as plants are concerned, the most important evolutionary change of the Cretaceous period was the rapid diversification of flowering plants. These spread across the separating continents, along with thick forests and other varieties of dense, matted vegetation. All of this greenery not only sustained the dinosaurs, but it also allowed the co-evolution of a wide variety of insects, especially beetles. The Cretaceous-Tertiary Extinction Event At the end of the Cretaceous period, 65 million years ago, a  meteor impact  on the  Yucatan Peninsula  raised huge clouds of dust, blotting out the sun and causing most vegetation to die out. Conditions may have been aggravated by the collision of India and Asia, which fueled an immense amount of volcanic activity in the Deccan Traps. The herbivorous dinosaurs that fed on these plants died, as did the carnivorous dinosaurs that fed on the herbivorous dinosaurs. The way was now clear for the evolution and adaptation of the dinosaurs successors, the mammals, during the ensuing Tertiary period.
