Eating Disorders Essay -- Health, Diseases, Anorexia Nervosa, Binge Ea

Introduction Eating disorders are psychological problems marked by an obsession with food and weight. There are four general categories of eating disorders these are; Anorexia nervosa, Binge eating and Bulimia nervosa. However this disorder affects individuals of various age groups; it has become more popular among teenagers these days. For the purpose of this research plan the writer will focus on age group of ages 15 to 19 because teenagers most vulnerable to eating disorders fall into this age group. Moreover, in doing so it will also be possible to determine the significance of this research and apply it to today’s lifestyle. Anorexia is a medical condition in which youngsters, mainly during the onset of puberty, begin to starve themselves thinking they are overweight, even though they are not. They remain under this illusion and as a result of being cautious they become extremely thin, bordering on ill health or sometimes death. Eating disorder in teenagers has become an area of con cern as it is a disease which is affecting the youth of today’s society. The purpose of this research is to identify the main cause of eating disorder in teenagers and help the young generation as they play a vital role for tomorrow’s future. Literature review Causes of anorexia The causes of anorexia are complex and no single factor has been identified. The actual cause of these disorder appear to result from many factors, including those that are genetic, media leading disorders, parental behaviours, psychological factors and negative family influence. Anorexia Nervosa Parentlink (2008) describes anorexia as a disease where the individual person starves himself/herself even though he/she is hungry and is seen to be very thin. Furt... ...d happy life themselves. If taken care of for instance proper care from the family, teenagers are less likely to suffer from the eating disorders. This then means parents can control teenagers eating habits with maximum supervision. Since family lifestyle tends to affect teenagers eating habits. In recent studies by Fornari and Dancyger (2003) notes that family whereby parents are overly controlling, a teenager tends to put on a lot of emphasis on looks, diet them or criticizes their body appearance can cause anorexia. In this case it’s the family’s duty to provide support and care to the general development of the teenagers for a better future. Yoon et al. (2005) argued that families, friends, and dating partners play a role in the development of anorexia and other eating disorders by the generation and transmission of different messages about the thin-ideal.

Nurse to patient ratio in emergency rooms

The presence of emergency rooms in hospital provides the people with additional service especially in time of need. Emergency situations are given the attention they deserve and the people affected are extended prompt care and treatment in emergency rooms. â€Å"When you need help right away, the best place to go is the nearest hospital emergency room. Also called the ER, this place is open 24 hours a day. Nurses and doctors are there day and night to care for medical problems that need quick attention† (â€Å"What Happens In The Emergency Room†). The presence of doctors, nurses, and equipment are important factors in making the emergency room serve its purpose. Due to the number of emergency situations that occur on a daily basis however, said factors must be assessed in order to determine whether or not emergency rooms still provide ample assistance to people in a given community.One such factor of great importance is the number of nurses assigned to a shift in an eme rgency room. It is important to review how the number of nurses in an emergency room can affect the rendition of service to patients, and ultimately, how it affects mortality of patients in the hospital. Nurses are of value and importance inside the hospital. As correctly stated by Underwood,Nurses in the community are well prepared and well positioned to improve the health and well-being of people living in the community. The available evidence is convincing that nurses in the community have a positive impact on the health of individuals, families, and populations (2003).Admittedly, it is the doctor who orders what type of treatment and prescribes the necessary medication to a certain patient. However, it must be noted that without the nurse, the orders of the doctor will be put to naught since no one will be in charge in the execution of said orders. So also, the basic things preliminary to the treatment of the patient are usually done by the nurse. Thus, it necessary to analyze h ow understaffing of nurses in the emergency room could affect the services these nurses render to the patients who are urgently in need of help. Ultimately, it can be seen that the safety of the patients are dependent on the number of the nurses that are assigned to the emergency room in a given shift.The quality of the services provided and delivered by the nurses depends on the tasks assigned to them and to the number of patients they attend to. Based on studies conducted, increase in the ratio between patients and nurses are advantageous as regards the delivery of health care services to the patients. The opposite is not only disadvantageous to the interests of the patients, but rather, it could lead to deterioration of health or even death on the part of the patients. The staffing of nurses in emergency rooms is an important issue must be addressed. The patient and nurse ratio affects the work load of the nurse, medication errors, waiting time of patients, delivery of care and m ortality. Said issues must be address in order to ensure that emergency rooms are still effective venues for rendering treatment to emergency situations.Increase in the patient to nurse ratio would ensure better rendition of services to patients. Firstly, delays will be prevented by higher ratio between patents and nurses inside the emergency room. Clearly, there are instances where more patients need care and there are only a handful of nurses available at a given shift. In these cases, not all the patients will be attended to promptly. Some would have to wait because the nurses would have to focus on the other patients who are in need of more urgent care or treatment.The other patient, also needing emergency treatment, will necessarily have to wait. As aptly stated,  excessive delays are akin to possible adverse events from the supply side (pressure experienced by the nurses) and from the demand side (waiting patients), both of which factor into the overall quality of care. Acco rdingly, we pose the nurse staffing problem in terms of finding staffing levels that guarantee a bound on a specified probability of excessive delay [†¦]  staffing levels are set to prevent the assistance of patients in need from being delayed longer than a specified time constraint [†¦] (Vericourt and Jennings).It must not be forgotten that emergency rooms are assigned in a hospital in order to provide attention to emergency cases. If patients are made to wait for a long period of time before their ailment can be attended to, then the purpose for which emergency room exists is not being served.  The adverse effect of the delay caused by a decrease in patient to nurse ratio is not limited to having the patient wait for treatment that he or she needs.Ultimately, the health of the patient is adversely affected.  delaying certain procedures can endanger patient health. For instance, the medical guidelines for certain myocardial infarctions recommend the immediate admini stration of aspirin. Delays also give rise to unfinished tasks, either because nurses fail to remember them later or because they abandon them in order to take care of more urgent procedures.In emergency rooms situations, time is always of the essence. Hence, the waiting time of the patient must be lessened, if not absolutely eliminated. The mere fact that the patient sought help from the emergency room means that care and treatment must be urgently administered to him. Having the patient wait due to the limited number of nurses that are available in a given shift means that the patient has to bear with his ailment before he can be attended to. This is contrary to the purpose of emergency rooms.Secondly, the increase in the patient to nurse ratio will clearly eliminate medication errors inadvertently done by nurses. It must be admitted that the number of patients assigned to a nurse at one given time largely affects the performance of the nurse concerned. If patients, more than thos e which one nurse can handle, are assigned to a nurse, there will be difficulty in attending to all of said patients. This could lead to error in administering the proper treatment to be given to a certain patient. Regardless of the competence of the nurses in the hospital, the weight of their work load can actually influence the quality of service that they deliver to the patients.In instances which involved the decrease of the ratio between patient and nurse, medication errors have been made by nurses. The commission of said errors eventually led to complaints from patients due to faulty and low quality of service that has been provided to them. One article recounted that a report from the Department of Health of Massachusetts revealed that â€Å"medical errors and complaints at hospitals have increased by 76 percent in seven years† (Why The Staffing Ratio Law Is Needed†) due to understaffing of nurses in emergency rooms.Thus, it appears that decrease in the ratio bet ween nurse and patient could actually lead to endangering the health of patients. This could also blemish the character and reputation of hospitals in the community because instead of ensuring the health of the patients, they accomplish the opposite.Lastly, and more importantly, the ratio between patient and nurse affects the quality of service given to, and the mortality of patients seeking help from the emergency room. As mentioned earlier, the delay in receiving proper care and the great possibility of errors in medication could adversely affect the health of patients. This is the same reason why a lot of States have resorted to the promulgation of laws involving the fixing of the ratio between patients and clients in the hospital. This is to ensure quality of the care provided to the patients. As correctly pointed out by Vericourt and Jennings,The rationale for implementing these ratios stems from the association between nurse staffing level and patient safety. Research studies suggest a significant connection between nurse workload and clinical outcomes. For instance, Aiken et al. (2002) conclude that the addition of one surgical patient to nurse assignments results in a 7% increase in mortality rates. The purpose of the mandated nurse-to-patient ratios is to provide a consistently high level of patient safety throughout the state. Ostensibly, safety is partially attained through manageable workloads among those who actually provide health care services.If decrease in the ratio between nurses and patients is countenanced, then a lot of patients would suffer because they will not receive the urgent treatment that they need. There is a possibility that their injury or ailment could actually worsen due to errors in treatment or medication. So also, there is a chance that due to lack of timely and proper treatment, death could ensue.The Institute of Medicine of the National Academies of Science reports that â€Å"nurse staffing levels affect patient outcomes and safety.† Insufficient monitoring of patients, caused by poor working conditions and the assignment of too few RNs, increases the likelihood of patient deaths and injuries at a time when avoidable medical errors kill up to 98,000 people in U.S. hospitals every year (â€Å"Why The Staffing Ratio Law Is Needed†).This is, unquestionably, a serious issue that must be addressed. As mentioned above, the emergency room is a place where quick attention could be given to patients who are in need. There is a promise that ailments and injuries will be treated right away in order to save the patient. However, due to understaffing of nurses in emergency rooms, it appears that chances of death are even heightened.All the materials related to the issue at hand are in agreement that the fixing of the ratio between patients and nurses is an important issue that deserves attention. Not only does it affect the workload of the nurses, but ultimately, it affects the health and safety of the patients seeking help from the hospital. In a survey conducted, even the nurses themselves agree that understaffing is a serious problem encountered in most hospitals. â€Å"The survey data demonstrate that nurses view understaffing as a serious problem when it comes both to the quality of care that patients receive and to nurse burnout. For example, three in five (59%) hospital nurses say that the staffing level at their hospital is having a negative impact on the quality of care patients receive† (Hart, 2003).In conclusion, emergency rooms and nurses play an important role in the society when it comes to giving urgent care and treatment to patients seeking help. Mere assignment of nurses to emergency rooms is not sufficient. A sufficient number of nurses must be assigned to a certain shift in the emergency room in order to meet the demands of the people in need. Undeniably, nurses play different roles while they are at work.Its goal is to promote and preserve the healt h of populations and is directed to communities, groups, families and individuals across their life span in a continuous rather than episodic process. The role and activities include: care/service provider; educator; consultant; community developer; leader; enabler; advocate; communicator; resource manager/planner; coordinator; team member/collaborator; researcher/evaluator; social marketer; and policy formulator (Underwood, 2003).If said duties are expected of nurses, then it appears that said duties cannot be accomplished if only a few nurses are assigned in a certain shift.   Research proves that decrease in the ratio between nurses and patients affect adversely the performance of nurses. They commit errors in medication and are not able to provide proper care and treatment to all the patients assigned to them. On the other hand, increase in the ratio between nurses and patients ensure that only the best quality service and care will be given to the patient. Proper attention an d adequate attention is ensured because the nurse is able to focus on the patient. Ultimately, in increasing the ratio between nurses and patients, nurses are able to perform their duties efficiently, and the patients receive the care and attention that they deserve.

The Symbiotic Relationships between Microbial Organisms and Plants

The Symbiotic Relationships between Microbial Organisms and Plants | With Concentrations in Rhizobium & A ; Mycorrhiza Introduction– There are many capturing microbic beings that spend a important part of their life rhythm shacking in the dirt profiles. These beings include roundworms, Protozoa, Fungis, bacteriums and different arthropods. Together they play critical functions in act uponing dirt features and keeping healthy dirt profiles. In our instance, we will be chiefly concentrating on Fungis and bacteriums. Fungi and bacteriums are really normally found inside the dirt and they have huge impact on dirt birthrate and works growing. It is instead challenging to analyze their interactions with workss and their single maps. The intent of this research paper is to derive a deeper comprehension of their perplexing relationship with workss ; and most significantly, to carry through my intense wonder of why such symbioses are so indispensable to the well-being of our assorted ecosystems and even for us worlds? Plant Foods– The three primary foods workss reliant to a great extent on are nitrogen, P, and K. Since we will be extensively analyzing the functions of bacteriums and Fungis, thereby we are more concerned with N and P. So so, why do workss necessitate those foods? Nitrogen is one of the indispensable chemical elements workss needed for growing and reproduction. It is a constituent of chlorophyll and thereby critical for photosynthesis. It is besides a major constituent of amino acids, the edifice blocks for proteins ; and without proteins, workss would shrivel and decease ( U.S. Department of Agriculture, 2015 ) . In add-on, some of the proteins act as structural units in works cells while others act as enzymes, doing possible many of the biochemical reactions on which life is based. Nitrogen is besides a constituent of energy-transfer compounds, such as adenosine triphosphate, known as ATP. ATP grants cells the ability to conserve and utilize energy released in metamorphosis. Nitrogen is besides a important constituent of nucleic acids such as Deoxyribonucleic Acid, known as Deoxyribonucleic acid, the familial stuff that allows cells to turn and reproduce. Phosphorous is another critical food both as portion of several cardinal works construction compounds and as a contact action in the transition of legion cardinal biochemical reactions in workss. Phosphorous is notably responsible for its function in capturing and change overing sun’s energy into utile works compounds. Like N, P is a critical constituent of DNA. It is a constituent of RNA, the compound that reads the DNA familial codification to construct proteins and other compounds indispensable for works construction, seed output and familial transportation. The construction of both DNA and RNA are linked together by P bonds. Another similar belongings that phosphorus portions with Nitrogen is that it is besides critical constituent of ATP. ATP signifiers during photosynthesis, and uses P within its construction, and it processes from the beginning of seedling growing through to the formation of grain and adulthood ( U.S Department of Agriculture, 2015 ) . Therefore, both N and phosphoric are indispensable elements needed for the general wellness and energy of all workss, they help to increase chaff and root strength, better flower formation and seed production and support plants’ development throughout their full life rhythm. Without neither N nor phosphoric, there would be no life on Earth as we know it. Nitrogen Fixing Bacteria Analysis –Rhizobium As mentioned above, N is an indispensable food for workss as it is portion of their nucleic acids and proteins. Nitrogen can be in many signifiers, such as Nitrogen Gas, Ammonia, Nitrate, Nitrite, Ammonium and Nitrous Oxide. Dinitrogen or N gas is really abundant and makes up 78 per centum of our ambiance. Unfortunately, workss are unable to utilize them straight because they lack the necessary enzymes to change over the gas into biologically utile signifiers. The job here is that N gas is non really reactive ; it will barely interact with other chemicals to make new compounds ( Brady & A ; Weil, 2010 ) . However, there is a manner to repair the unserviceable signifier through either chemical or biological procedures ; and the repair procedure itself is called nitrogen arrested development. The nitrogen arrested development procedures will interrupt down the ternary bond that held the N atoms together and liberate them up for transmutation. The atoms can so be integrated with other e lements to organize ammonium hydroxide, ammonium or N dioxides. Now we introduce the construct of biological N arrested development. It was foremost discovered by German agronomist Hermann Hellriegel and Dutch microbiologist Martinus Beijerinck. Biological N arrested development is the procedure of transition of atmospheric N into ammonium hydroxide by beings through an enzyme called nitrogenase ( Peters, Fisher & A ; Dean 1995 ) . Within the nitrogenase, there are two important protein composites that are responsible for the decrease of N gas, viz. Fe-protein & A ; MoFe-protein. The reductive reaction can be expressed by the equationN2 + 8H+ +8e- + 16 ATPi?2NH3 + H2 + 16ADP + 16Pi. Think of the Fe-protein composite as a power house and the MoFe-protein composite as a mill. A mill requires energy to bring forth merchandises, and that is when the power house stairss in to run into the demand. Fe-protein ( the power house ) receives elections ( energy ) from a flavedoxin ( an negatron reassigning protein, in this instance, think of it as a air curr ent turbine ) and transfers them further to the MoFe-protein ( the mill ) . The negatron transferring is made possible by the coincident hydrolysis of ATP to ADP & A ; Pi, where more energy is produced to back up the transit of negatrons. MoFe-protein so takes the negatrons, atmospheric N gas, and H converts them into ammonium hydroxide along with a remnant H molecule. It is of import to observe that enzymes within nitrogenase can be destroyed by free O molecules. Thereby, organisms that fix N must guarantee the enzymes do non acquire exposed to oxygen ( Brady & A ; Weil 2010 ) . The being that fix N are a type of dirt bacteriums and they are jointly called Rhizobium. In order to protect nitrogenase, they form this intricate symbiotic relationship with leguminous workss, such as soya beans. They begin by infecting the plants’ root hairs and the cortical cells ; it leads the formation of root nodules that serve as the safe oasis for nitrogen arrested development ( Long, 2004 ) . The procedure in which the nodules signifier is really absorbing. The plants’ root hairs release certain chemical signals to pull rhizobia bacteriums that are present in the dirt. Rhizobia enter the root and get down to proliferate and do an infection yarn to organize. The infection yarn will so turn into the cerebral mantle of the root. When the infection yarn has reached far plenty into the plants’ root, it will let go of bacterial cells, which become bacteroids in root cells. Nod factors from the bacteriums will do cortical cells to split and take to the eventual formation of nodules. It is curiously interesting that the plants’ immune system is digesting the infection ; alternatively of killing the bacteroids, they keep them within their cells. When Rhizobium are inside the nodules, they do non hold to cover with free O molecules and now can safely utilize nitrogenase to cut down atmospheric N to ammonium hydroxide. Through this symbiotic relationship, the host workss gain benefits from utilizing an eternal beginning of N from the ambiance that are now in a more biological useable signifier. In return, rhizobia receive saccharides generated through photosynthesis for energy ( since it takes energy to execute the transition ) , every bit good as a protected shelter in which for them to populate and turn ( Brady & A ; Weil, 2010 ) . Plants are now able to use the ammonium hydroxide ensuing from bacterial N arrested development for growing. The compound is transported into works tissues and is so incorporated into aminic acids, which are so made into works pr oteins. For cases, soya beans and peanuts produced by leguminous plant workss contain extraordinary high degrees of protein and are among the most of import agricultural beginnings of protein in the universe. The curious mutualism between legume workss and Rhizobium illustrate the manner they help to prolong each other’s lives. Consequently, it is besides assisting us worlds to prolong our lives. In fact, our well-being is to a great extent dependent upon this important and yet low-cost beginning of protein. We consume them as portion of our basic diet and we use them as animate being provenders. Farmers, they take the advantage of this mutualism and utilize it to fertilise their harvest land through harvest rotary motion – for case, they use soya beans and other leguminous plant workss in rotary motions with grass harvests such as maize or wheat to straight shoot biological useable N back to the dirt ( U.S. Department of Agriculture’s, 2015 ) . Nitrogen arrested development procedure besides at the same time contributes to dirty birthrate because the works roots leaves behind some of the biologically available N. Rhizobium is a natural and environmentally friendly ma nner to fertilise workss as oppose to chemical fertilisation that use a non-renewable resources, such as natural gas. Taken together, who would hold of all time thought that such elusive relationship between workss and bacteriums can hold such an tremendous consequence on all the species’ endurance. Alimentary Delivering Fungi Analysis – Mycorrhiza As antecedently stated, phosphoric is one the most indispensable foods for many life beings, particularly for workss. Plants must utilize phosphoric for normal growing and adulthood. The component plays a immense function in photosynthesis, energy storage and transportation, cell division and many of import procedures in workss. Without phosphoric, a works would non even be able to finish its normal production rhythm. Soil phosphoric is classified into two groups, organic and inorganic. Organic phosphoric can be found in works residues and manures. Inorganic P consists of apatite ( a group of phosphate minerals and original beginning of all phosphoric ) and composites of Fe and aluminium phosphates and P absorbed onto clay atoms. The job associated with phosphoric and its relevant compounds are their solubility. The solubility of both organic and inorganic P is highly low and merely a really little fraction of dirt P is present in solution at any one clip. To give a position, most dirts contain less than a lb per acre of soluble P and with some dirt incorporating even less ( Ingham, Trofymow, & A ; Coleman, 1985 ) . Since there will be really small P in dirt solution and most of them being stuck onto clay atoms due to molecular attractive forces, it would be rather hard for workss to seek for and intake P. However, merely because workss themselves are unable to obtain the foods they need, it does non intend they can non inquire for aid from other being ; for cases, mycorrhizal Fungis. First and first, it is of import to understand what Fungi are and how do mycorrhizal fungi differentiate themselves from their sort. Fungi are primary beings that can non synthesise their ain nutrient and are really dependent on complex organic substances for C. There are three functional groups of Fungis, decomposers, pathogens, and mutualists. First, we have decomposers or saprophytic Fungis ; they are an of import portion of our ecosystems and play a necessary function in immobilising and retaining foods in the dirt by devouring foods in organic affair. They are capable of degrading cellulose, proteins and lignin, some of which are extremely immune to breakdown ( Smith & A ; Read, 2008 ) . They can change over dead organic affair into their ain fungous organic structures, C dioxide and organic acids. They are besides indispensable for the decomposition of difficult woody organic affair. Through decomposition, they help to supply a fresh beginning of indispensable foods for new coevalss of life. Second, we have infective Fungis, such as Verticillium, Phytophthora and Pythium ; they are really rather damaging to the wellness of workss. Those beings will perforate the works and break up the life tissue, doing the works to be weakened and alimentary deficient or even decease ( Smith & A ; Read, 2008 ) . Last, we have mutualistic Fungis that form reciprocally good relationships with workss. Mycorrhizal Fungis are possibly the most well-known amongst mutualists. There are four groups of mycorrhizal Fungis, arbuscular, ectomycorrhizal, ericoid and orchid ( Smith & A ; Read, 2008 ) . Our chief focal point will be on arbuscular mycorrhizae, they are the most common signifier of mycorrhiza, particularly in agricultural works associations. This fungus has arbuscules which are growing formed inside the works root and have many little projections traveling inside the plants’ cells. Arbuscules are believed to be the major site where the C and alimentary exchange between works and fungus occurs. It is named so due to their â€Å"tree-like† construction, arbuscules are created by perennial ramification of hyphae once they enter a cell within a works root. Fungus kingdoms are heterotrophic beings, intending they must absorb their nutrient. They have the capableness of absorbing elements such as P and N which are indispensable for life. Plants are autophytic ; they produce their ain nutrient in the signifier of saccharides through the procedure of photosynthesis. It is of import to observe that plants’ roots frequently have trouble obtaining and absorbing Ps due to the element’s stationariness and unsolvability inside the dirt. However, arbuscular mycorrhizae can assist workss to widen the volume of dirt explored through their hyphae. Mycorrhizal Fungis are characterized by those really thin hyphae, which are between 1 and 10 thousandths of a millimetre in breadth. Impressively, up to 5 metres of populating hyphae can be extracted from 1 gm of dirt. These hyphae explore the dirt expansively and intercept phosphoric compounds, it would so bring forth enzymes to solubilize P from inorganic stone, absorb the food, and transpo rt them back to the host-plant ( Baum & A ; Gruda 2012 ) . The hyphae would organize webs between neighbouring dirt atoms, between roots and dirt atoms or even between roots of different workss. And since they are arbuscular mycorrhizae, they besides form webs inside the roots they colonize. These intricate webs of hyphae are normally referred to as mycelium. In this instance, both workss and fungus depend on the symbiotic relationship to develop and last. At the terminal, they both benefit from each other. Mycorrhiza fungi usage mycelium to happen phosphoric and transport it back to the host works. In exchange, the Fungis receive saccharides as a signifier of payment for assisting the workss ( Brady & A ; Weil, 2010 ) . In add-on, mycorrhizal associations may besides assist to cut down onslaught from root pathogens through the secernment of bacteriums killing enzymes and antibiotics ( Lugtenberg & A ; Bennet, 1991 ) . It is undeniable that mycorrhizae play an huge function in sustainable works productiveness and care of dirt construction. Furthermore, it is estimated that about 90 % of all vascular land workss ( land workss that have lignified tissues, the xylem, for carry oning H2O and minerals throughout the works organic structure ) live in some association with mycorrhizal Fungis. Mycorrhizal associations are besides seen in dodo rec ord and are believed to be one of the lending factors that allowed early land workss to suppress the land around 450 million old ages ago. The symbioses between workss and mycorrhizae affect our ecological procedure in many intricate and elusive ways. And knowledge refering mycorrhizal Fungi has well helped us to progress in engineering that made possible the production of microbic inoculums. Those inoculums act as bio-fertilizers which significantly improved the endurance, growing and constitution of trees and harvests ( Baum & A ; Gruda, 2012 ) . We are able to bask the shadiness of oaks, decorate Christmas trees, and eat delightful blueberries all thanks to the benefits from the concealed universe of mycorrhizal Fungis, a universe that helps to prolong the endurance of about all of the earth’s land workss. Decision– Symbiosis is a alone relationship exhibited between two beings where they live together in a close association. The two beings would work together and exchange foods to guarantee each individual’s endurance. The mutualism between legume workss and Rhizobium provide us humans a important and yet low-cost beginning of protein. The mutualism between vascular workss and mycorrhizae has a enormous impact on the well-being of many ecological procedures due to the fact it supports the endurance of the earth’s huge land workss. We are able to bask many things in our life all thanks to symbiotic relationship amongst these microbic beings. I personally feel that many of us have gotten so busy with carry throughing our wonder towards outer infinite that we have forgotten to appreciate what are concealed underneath the land. Another philosophical takeout from composing this research paper is that I have learned the value of mutuality. None of us are born perfect, a nd it might be better if we can swear and trust on one another in society for endurance and to boom as people. For case, if I’m inadequate at making certain things, I can possibly inquire my friend to assist me out, and in exchange I can assist him or her with something that she is non good at. Therefore, I believe that by working together hand in glove and collaboratively, we can optimise our consequences and accomplish astonishing things that we otherwise would non be able to accomplish by ourselves entirely.

Free Essays on Wuthering Heights Essay On Change

Twenty questions. I’m thinking of a word that is deceiving because it contradicts it’s own meaning. Change. Heraclitus once said, â€Å"Nothing is permanent but change.† If choosing to change oneself a person is choosing to change their destiny, and that option is always present. In the novel Wuthering Heights, Emily Brontà « presents life as a process of change, and demonstrates it through a relationship in which change took place and there were pleasant results, and the parallel relationship based upon refusal to change and it’s faulty outcome. A similar theme is present in the novel Things Fall Apart by Chinua Achebe, however instead of relationships, it deals with the introduction of new ideas or situations that are either accepted and dealt with, or rejected. The reason for lack of change in both novels was fear, pride, and reluctance to let go of the past. The young Catherine of Wuthering Heights had utter contempt for Hareton Earnshaw initially because he was virtually illiterate and savage. Over time however, the two became close friends and lovers, all as a result of Hareton’s willingness to learn to read and become a gentleman, and Catherine’s willingness to disregard her arrogance and teach him. A direct quote representing the change that took place in Catherine is, â€Å"and I was miserable and bitter at everybody; but, now I thank you, and beg you to forgive me, what can I do besides?† (Pg. 322) One night they were each calling the other a witch or a dog, and the next they were sitting comfortably in front of the fire reading together. By the conclusion of the book they were engaged. It is plain to see what fortune the readiness to change brought upon Catherine and Hareton. At one point in Things Fall Apart, the main character Okonkwo and his family were exiled to spend 7 years in another village. This took a great deal of change for the family, and they chose to make the best of the situation at hand. This earned ...

The 4 Stages of the Ladybug Life Cycle

The 4 Stages of the Ladybug Life Cycle Ladybugs go by several other names: lady beetles, ladybug beetles, and ladybird beetles. Regardless of what you call them, these beetles belong to the family Coccinellidae. All ladybugs progress through a four-stage life cycle known as complete metamorphosis. Embryonic Stage (Eggs) Wilfried Martin / Getty Images The ladybug life cycle begins with an egg. Once she has mated, the female ladybug lays a cluster of 10 to 50 eggs. Usually, shell deposit her eggs on a plant with suitable prey for her offspring to eat when they hatch; aphids are a favorite food. Between spring and early summer, a single female ladybug may produce up to 1,000 eggs. Scientists believe ladybugs lay both fertile and infertile eggs in the cluster. When aphids are in limited supply, the newly hatched larvae will feed on the infertile eggs. Larval Stage (Larvae) Pavel Sporish / Getty Images In about four days, the ladybug larvae emerge from their eggs. Species and environmental variables (such as temperature) may shorten or lengthen this time frame. Ladybug larvae look somewhat like tiny alligators, with elongate bodies and bumpy exoskeletons. In many species, the ladybug larvae are black with brightly colored spots or bands. In the larval stage, ladybugs feed voraciously. A single larva can consume dozens of aphids per day. Larvae feed on other soft-bodied plant pests as well, including scale insects, adelgids, mites, and insect eggs. Ladybug larvae dont discriminate when feeding, and will sometimes eat ladybug eggs, too. The newly hatched larva is in its first instar (a developmental stage that occurs between molts). It feeds until it grows too big for its cuticle (soft shell), at which time it will molt. After molting, the larva is in the second instar. Ladybug larvae usually molt through four instars, or larval stages, before preparing to pupate. The larva will attach itself to a leaf or other surface when it is ready to pupate (metamorphose into its adult form). Pupal Stage (Pupae) Pavel Sporish / Getty Images In its pupal stage, the ladybug is usually yellow or orange with black markings. The pupa remains still, attached to a leaf, throughout this stage. The ladybugs body undergoes a remarkable transformation, directed by special cells called histoblasts. The histoblasts control a biochemical process through which the larval body is broken down and reformed into the adult ladybug. Depending on the species and environmental variables such as temperature, the pupal stage may last 3 to 12 days. Imaginal Stage (Adult Beetles) Jà ¶rg Mikus / EyeEm / Getty Images Newly emerged adults, or imagos, have soft exoskeletons, making them vulnerable to predators until their cuticles harden. They also appear pale and yellow when they first emerge, but soon develop the deep, bright colors for which ladybugs are known. Adult ladybugs feed on soft-bodied insects, just as their larvae do. Adults overwinter, usually hibernating in aggregations. They mate soon after becoming active again in the spring. How to Find Ladybug Eggs and Larvae If you have a garden plant that is prone to aphid infestations, you have access to prime ladybug habitat. If you want to familiarize yourself with the ladybug life cycle, visit this plant daily. Take your time examining the leaves, lifting them to observe the undersides, and youll likely find a cluster of bright yellow eggs.  Within a few days, tiny ladybug larvae will hatch, and youll find the odd-looking immature ladybugs on the prowl for aphids. Later, youll see dome-shaped pupae, shiny and orange. If aphids are abundant, adult lady beetles will hang around, too.

Sexism in Popular Culture Dissertation Example | Topics and Well Written Essays - 3000 words

Sexism in Popular Culture - Dissertation Example Important here to note is there is a significant portion of the movies in Hollywood and instances in the popular culture, where one can easily find female characters, whether lead or supporting, with similar traits, whether it be film, television, theatre, drama, advertising, comic books, literature, video games, cartoons and others (Stephanie & Brabon, 2009, p. 225). The rise of feminism and the debate about the identity of women has forced many filmmakers directors and producers in the media to move away from the traditional emotionally unstable and weak concept of women and portray women in a more realistic and empowering way. This created a demand of â€Å"strong female characters† and over the past couple of decades, many strong female characters have emerged to fill this gap. However, many feminist critics and even other experts have challenged and criticised the idea and depiction of strong female characters. This paper is an attempt to explore and analyse the depiction of women in film and video games, while simultaneously exploring the concept of â€Å"strong female characters†, its ideological grounding and the criticism. ... Towards the end, the Hero would come and save them to live a life happily ever after. However, towards the mid 20th century, the rise of feminism created discontent amongst female viewers and stakeholders of Hollywood that this portrayal of women as â€Å"needy† and â€Å"weak† creatures in sexist. In order to address the same, writers came up with female characters that would be trapped by the villain only after putting up a strong fight (Hollows & Moseley, 2006, p. 58). These women, to a certain degree, had skills normally possessed by men. They could drive sport cars, use guns, had physical strength, was comfortable with her body and could outdrink any man. Even when she could put a fight, these â€Å"strong female characters†, in the end of the movie, would get themselves into trouble and that also in the sexiest way possible. Surprisingly enough, even when she could put a fight to resist the pressures of villain, she would never get a black eye or get physic ally injured probably because they same would decrease her appeal. The point here is that all the â€Å"strength† added to the female character was just an attempt to make her a better and more attractive prize for the hero at the end. (Meyers, 2008, p. 172 (Gillis, et al., 2007, p. 413). The problem with the commonly used phrase â€Å"strong female characters† or â€Å"strong females or women† is that it is ironic, paradoxical and contradictory within itself. Female characters are viewed as strong only when they are able to exhibit dominance, assertiveness, tendency for violence, boldness, rudeness and impudence that is characterised with male characters (Haase, 2004, p. 340). The point here is that in order to become â€Å"strong female characters†, women have to give up the

Finance Personal Statment Statement Example | Topics and Well Written Essays - 500 words

Finance Statment - Personal Statement Example I am motivated to beat the odds and change the Saudi Arabia culture in order to open the doors to female workers to aspire higher professional goals. I want to join your program for several reasons. One of my career goals is to pursue a career in teaching in the future. Most universities require its professor’s to hold PhD degrees. During the first year of the program I hope to get acquainted with the faculty and sharpened my research skills in order to select a good topic for my thesis. I am very passionate about finance. In high school I started following local and international stock markets and reading the financial page of the newspaper. A few years later once the internet arrived at my country I had greater access to articles and financial news. I wanted to study finance at the university, but they did not teach it for girls at that time in Saudi and my parents did not allow me to study abroad for cultural reasons. This led me to choose accounting as my major. Accounting is often regarded as the cousin to finance since both practices are interrelated. I got married in my last year of college on October 2001 and had my first child in 2003 and my second in 2005. Since 2002 I was signing petitions to allow women to enter Saudi organization of certified public accountants so they can hold the Saudi CPA. Finally in 2004 the acceptance was granted. I am a goal oriented, assertive, self motivated, and a hard worker that is not afraid of a challenge. I am also ambitious, a good analyzer, team player, and a great leader. I am aware of the impotents of self development. I have attended several workshops on the subject. In the latest which was about women leadership, the presenter asked what about the main challenges Saudi women faced while doing their dissertation. I thought a professional women network could be the solution. I took the initiative and
