More impotant than a baby sitter EssayIn todays world we live our lives constantly enquire what we can do to better ourselves or our tiddlerren. When in fact we should be concerned with what we didnt do already. Pet scans and other research show that from yield to age 6 are the most crucial years for brain development. At just the age of three, a childs brain is double as active as the average adult brain and it stays that way for the first decade of life. With the world at its most competitive period, we wishing our children to be as logical and knowledgeable as possible.Preschools are a keen way to focus on the essential components that in allow a childs brain to develop. Even though some parents treat preschool as a baby sitter, they may be missing the bigger picture that these great facilities are making. Babies are born learning, they make synapses connections throughout the day. And these connections are only made if they are a repetitive action, like putting the sq uare forfend through the square hole. This is considered the wiring of the childs brain and only dramatizes place during the young years.Teachers know this and make the children preform the repetitive actions so the connections they are experiencing are strong and last throughout the rest of their lives. Preschoolers learn so much so fast its like they are making leaps in their education. If ein truthone was educated starting at the preschool level who knows how much more successful and developed this world would be. Preschools offer a safe environment for children to interact for maybe all the same the first time. This one on one contact is for proper development the child learns how to wait, take turns and how to listen.This helps determine personality for the long run of the students life. These experiences must happen during preschool age to have a long term effect and the child benefit. Children also learn motor skills in preschool and the downy child friendly rooms pr un constipatedt any accidents or damage to their fragile bodies. They are able to try new movements and exercise their motor skills all while having fun. Music is another item introduced to the children for the first time. Musically inclined people have found to be introduced to music at a very early age according to Educational Expert Barbra Callaghan.And music has positive effects with originality and creativity. And its hard to call it a preschool without arts and crafts, this type of hand eye coordination goes hand and hand with the skills learned from music. Music is also a great tool for memorization, face it, when you think about the alphabet that same aura they play in preschools comes to mind. It also teaches rhythm and tempo and stimulates their brain to perform as a sponge to soak up information in plumping amounts.The first day of kindergarten can be extremely confusing and overwhelming for some children, but for children that have been enrolled in preschool its just a gang bigger building with new people. Preschool has been called the boot camp of education, because it is designed relatively similar to elementary school. And the statistics prove preschool helps in the success of public school. In 2009 a study by Duke University showed that in America, 59% of high school graduates were exposed to preschool at some time, and 41% received no education earlier to kindergarten.Thats an astounding number considering the high school dropout rate in 2009 was 16% according to CNN, and its safe to say more than half of them were not exposed to preschool in their younger years. Preschools are designed to be fun for small children, and they are. But the children are learning things they will need for the rest of their lives without even realizing. Almost every situation life brings to us on a daily basis can be traced back to the developmental years that take place during preschool. Whether its to help you develop independence, concentration, or even your a cademic foundation is developed in preschool.Think about all the children that are overleap of this solid start to education. Preschool has a greater purpose than being a babysitter Its something we can use to better ourselves for more breakthroughs with medicine and even discoveries of a new energy. It all starts at preschool, all babies are willing to learn its natural, we just have to give them the chance. Works Cited ARSLAN, EMEL, NESLIHAN DURMUSOGLU-SALTALI, and HASAN YILMAZ.

What Makes Art Art Essay Example for Free

What Makes Art Art EssayWhat makes Art Art? Can Art be de? ned? An ar? st female genitals create anything and be sick their mark on it and deem it as art. I believe art to be a sculpture, unhinge? ng, or any piece of crea? ve work that brings recreation to the ar? st and an apprecia? on from the beholder. Art allows you to view the world through someone elses eyes and obtain their perspec? ve on the military issue at hand.Art is everywhere around us. It is expressed in many forms and fashions. From railroad car gra? , a formal piece in a museum, a one of a benevolent piece of jewelry or designer fashion clothing, it is all forms of art. Art can bring out an array of feelings in people. Some pieces of art usher happiness or focus on beauty, which would in turn bring out joyous feelings. Art can also display images or subject lines that are not as pleasant to entertain at ?mes which can allow us to be compelled to a feeling of sadness. Art can be a therapeu? c way to deal with emo? ons. Au? s? c children and people dealing with tragedies can o(en express themselves and deal with emo? ons through art. I genuinely enjoy pain? ng old furniture and giving it a new look, a new life.It tends to remind me that all things in life can be restored and made beau? ful again with some work and determina? on. No ma*er what the circumstances or situa? on it can always be made into something beau? ful. Art attends to always tell a story even though words are never spoken. My concept of art is pain? ngs, sculptures, drawings, or anything that is created or transformed at the hands of the ar? st. I personally tend to enjoy pain? ngs that are of landscapes and nature. I always seem to navigate to the pain? ngs, especially oil, that remind me of ? mes during my childhood.Pain? ngs of a countryside with a barn and rolling hills or a grandfather ? shing with a child on the banks of a pond, takes me back to a happy place in my life. I truly then feel like I am understand ing what the ar? st is meaning to depict. Marsh Farm by Darko Topalski is a simple but impressive pain? ng to me as it reminds me of a farmhouse that used to sit on a hill across the ? eld from my childhood home. I ? nd colors to be in0uen? al in bringing out emo? ons when observing a piece of art. I enjoy art that has affectionate, muted colors as a feel that give that feeling of serenity. I think pain? ngs with warm or vibrant colors tend to depict a much happier and content scene.The content is much more important to me than the formal quali? es. Once again, I like the feeling of being able to connect with the ar? st and feel like he actually painted the picture looking through my eyes. I think for some people the formal quali? es would be more important. Thats the beauty of art, everyone has their own percep? on of the same piece. Art in my horizon is anything that we view and receive enjoyment. It also compels us to appreciate the talent of the ar? st. Art brings out emo? ons as we interpret the story and statement the ar? st is laborious to convey.

It can not eat much. and so on. This is a dilemmas for KFC have faced, because it has already realise the reputation of a fast food that continuously provides greasy un fit food .The company should do something about potential increase of stockholder value. universe one of the most popular fast food restaurants and with millions of people patronising the products and foods offered by the company, it is important the company adheres to ethical standards specifically in terms of providing healthy foods. However, it has been observed that Kentucky Fried Chicken is using oil which contains Trans productive acids.

The Postmodernism Of The White Noise English Literature Essay

The Post modernisticism Of The White resound English Literature Essay firearm the cultural and sociological landscape of White Noise is situated primarily in a postmodern world, the town of Blacksmith, the city that the Gladneys call home, seems to occupy a space betwixt modernism and postmodernism. The intrusion of technology, a factor which is often attri just nowed with the end of modernism and the beginning of postmodernism, in Blacksmith is described by sea dog when he says Babette and I and our childrenlive at the end of a quiet street in what was once a wooded area with deep ravines (4). Here, technology has transformed the physical and historical landscape of the town in such a way that makes the notion of progress, in regards to the progress of nature, a trope for confederacy, impossible, a defining characteristic of postmodern existence. Old Man Treadwell is however another example of the tension between modernity and postmodernity deep down Blacksmith. Treadwell, symbolic of the towns history, its modernity, has Babette read tabloids to him once a week. Within White Noise, tabloids represent the postmodern proof of information and it is only through Babette, an interpreter of sorts, that Treadwell is allowed access to the parvenue world and the new language of information. Understanding Blacksmiths transformation from a seemingly pastoral town to a modern city full of shopping malls, homes, and a host of other technological advancework forcets is important in that it helps, in part, to understand how jackstones historical sense of self, possibly an extension of the town in which he has lived in for twenty-one years, is at odds with the new postmodern world.More so than any character inwardly White Noise, bullshit, much like Blacksmith, exists between the cultural divide of modernism and postmodernism. While he maintains an acute awareness of the eternal and the unchanging (HARVEY ), the greater forces at work outside the sphere of exi stence, he is also overly infatuated with the object rather than the proceeds, that is to say, his sense of identity is the product of consumerist behaviors and goods. by and by Wilder, maw and Babettes youngest, suddenly stops crying after a seven-hour long fit, Jack says It was as though hed just returned from a period of wandering in rough remote and holy placea place where things are said, sights are seenof the most sublime and difficult dimensions (79). Here Jack is ac hit the sackledging the existence of otherworldly, social realities, a strong indicator of his modern sen durationnts given that one fundamental characterization of modernism is the power it bestows on the individual to create, improve, or reshape his or her environment, a la Wallace Stevens. During the Airborne Toxic Event, Jack describes the sight of the chemical plume as an enormous dark mass that moved like some death ship in a Norse legend (127). Later, when speaking of Babette, he says When she shovele d snow, she wore a furry headbandit made me think of the fifth century A.D. men standing around campfires speaking in subimputabled tone in their Turkic and Mongol dialects (171). In both instances, Jack, lending himself to the modernistic value of flavour to the past to understand the present, seems to suggest that he is aware that life, and all of the images, situations and occurrences that comprise it, existed, in some fashion, before him, an idea that directly contradicts the shallow, superficial sense of time and place associated with postmodernism. However, this notion of Jack as strictly a modernist is complicated early in the newfangled by his addiction, in every sense of the word, to objects and goods.When Jack and Babette run into Murray at the supermarket, Jack immediately begins to list the contents of Murrays shopping cart. He mentions the generic food and drink, the nonbrand items, the white packaging and simple labeling (18). His fixation on the objects that Murray is buying is directly related to his own sense of identity, one that is enveloped in a matrix of material goods, and so he searches for clues relating to Murrays identity, Murrays character, not inside Murray himself but from the objects associated with Murray. While Jack is aware of the utter shallowness which constitutes his identity, and subsequently everyone elses, formulation I am the false character that follows my name around (17), he is ineffective to remove himself from the depths of consumerism. This obsession, in large part, is due to Jacks struggle and overwhelming desire to participate in the emerging postmodern world.Another characteristic of Jacks which highlights his modernist sensibilities is his understanding that certainty, or the notion of absolute knowingness, is subjective, and as such, should be questioned and critically examined whenever it is presented as entirely established. For example, when Babette is reading horoscopes aloud to the family, which, like tabloids, operate within the novel as mediums of absolute certainty, Jack thinks to himself I tried not to listen when she got to mine (18), implying that he does not worry himself with trivial information that has become so pivotal, so meaningful, in the new era of postmodernity. However, Jack and his subjective notion of certainty are constantly at odds with the emerging culture and society of the novel.Throughout White Noise the most emblematic illustration of Jacks struggle to maintain his op role to the idea of total certainty while act to become an active participant in the new postmodern world is through various interactions between Jack and his son, Hein juicy. Heinrich, in both his youth and his large array of knowledge, represent the first generation of the postmodern world. While the other children, like Heinrich, have grown up in a hermetically besotted environment comprised entirely of technological and mass-media influences, Heinrich is old enough to understand the postmodern world around him and as such he rebels against the notion of modernism. While, for instance, Jack and his family gather up to watch the sunset, one that occurred before the Airborne Toxic Event (after which point the sunsets are described as being postmodern), Jack says Only Heinrich stayed awayhe believed there was something ominous in the modern sunset (61). Jack is aware of the disconnect between his son, a product of postmodern life, and himself, someone who still appreciates modern sunsets. While it may be read as an attempt by a father to connect with his son, Jacks numerous attempts at communication with Heinrich within the novel serves as a microcosm to Jacks attempt to communicate in the new cultural plane of postmodernism. In a conversation with Heinrich regarding the weather, the two badinage back and forth about whether or not it is currently raining. After a series of sharp counters between the two, Jack taking the subjective position (look at the windshiel dIs that rain or isnt it), Heinrich taking the objective position, or the idea of a media controlled collective subjectivity (Im only telling you what the radio said), the two baffle at the root of Heinrichs postmodern ideology. Jack, obviously frustrated by his failed attempt to participate in Heinrichs world, tries to coax Heinrich into admitting that it is in fact raining by presenting a situation in which a gun-toting man demands the truth to which Heinrich replies What truth does he want? (23). The preceding conversation centers around Heinrichs notion of language and relativity in regards to the notion of truth, or reality, in which the text seems to convey the notion that mass-media derives its power in the postmodern world by being acclimated to an individuals immediate desire for knowledge. Heinrich exudes information, Jack actively seeks it the tension here exemplifying one of the largest barriers standing between Jack and Heinrich and, more importantly, between Jack and the new postmodern world.As Jack progresses within the novel it becomes increasingly evident that while he recognizes the allure of objectness and the materialized notion of identity, in other words, postmodernism, he seems unable to wholly participate in it. More so than any other character, Jack is sensitive to the friction between the worlds of modernism and post-modernism. While he grasps the motives of the postmodern man to exist within the collective social network, saying to become a crowd is to keep out death. To break off from the crowd is to risk death as an individual, to scene dying alone (73), he also constantly questions the role of the new social ideology in regards to truth, knowledge, certainty, and simulation, notably observed in his interactions with SIMUVAC personnel where he questions the importance placed on simulations rather than subjective reality, or experienced reality. However, as momentum builds in his urges to break free from the understanding of postm odernism and exist within in it while maintaining his modernist awareness, his interactions with Vernon Dickey, his father-in-law, complicate his attempts to be a passive member of the object-centric, postmodern culture.From the idea that an individual has the power to create, improve, and reshape their environment to the importance of fanciful destruction, or the notion that in order to make something new, the old must be abandoned, destroyed, or disassembled, Vernon, in stark contrast to Jack, embodies modernism. Saying that he is shingle here, rustproofing there, his hands described by Jack as scarred, busted, notched and permanently seamed with grease and mud, his attention fixed on trying to spot something that demand replacing or repair (245), Vernon is very much in control of his environment reshaping it, building it, creating it. Jack, however, views himself against Vernon as fundamentally useless, mentioning that it put Vernon at an advantage to piffle about gaskets and washers, about grouting, about the things that built the world (245). Vernon, of course, recognizes the difference between himself and the postmodern world, asking Jack were people this stupid before television? (249). While Jack, to some degree, shares this sentiment, his desire to participate in the postmodern separates himself from Vernon, from modernism. Of creative destruction, Vernon, again contradictory of Jack, is not afraid of death. In fact, Jack notices that Vernon takes on a sarcastic pleasure in his own hacking and spasms, chronic coughs that, either from smoking or old age, or both, suggest a progression towards death, a progression towards something new the afterlife. In these instances, Jack realizes that his previous notion of existing within postmodernity as a passive modernist is unattainable given the fact that in the face of modernism, Vernon, he does not recognize the image of himself that is reflected. This realization propels him towards his decision to be w hat Murray calls a killer rather than a dier, that is to say, someone who acts in the world instead of simply being acted upon in other words, he refuses to be an object within the postmodern world who simply succumb, accept, and absorb. Jack, while no longer the fragmented modernist he once was, maintains his ability to examine and scrutinize, thus deciding for himself that the path of surrender and inaction required in the postmodern world is unacceptable and so, in what leave alone lead to the climatic encounter with Willie Mink, Babettes sexual liaison, he decides to become a subject, a killer, and heads to Iron City with the purpose of murdering Willie.Jacks encounter with Willie Mink, the physical physical body of post-modernism itself, is an allegory which speaks to Jacks resolve to overcome, with respect to himself, the seemingly impenetrable and nonparticipatory nature of the postmodernist world. However, Jacks interaction with the insensible, lobotomized Willie ultimatel y undermines his meaningful resolve to defeat postmodernism due primarily to the fact that Willie proves to be too strong in his objectness.Adorned with Budweiser shorts, the first indication of his physical personification of post-modernism, Willie drones out TV phrases and indecipherable riddles, saying some of these sure-footed bighorns have been equipped with radio transmitters (306) and the pet under stress may need a prescription diet (307). Like the diers described by Murray, Willie simply disarms and absorbs Jacks attempts at communication and dispatchment. The postmodern aura, or the collective unity of information, materiality, technology and knowledge, proves too powerful to be measurable and overcome by Jacks common standard of logic, reason, and discernment. So overwhelming, in fact, was the realm of postmodernism which existed within both Willie Mink and the motel room itself that it began to consume Jack. He says things began to glowthe air was rich with extrasensory materialWillie appeared to grow more vividthings in their actual statewhite noise everywhere (309-310). Overwhelmed and frightened, Jack puts into action his meticulously hyperbolize plan to kill Willie, the last-ditch effort to obtain the subjectness and authenticity that he felt would be realized by surmounting postmodernism. However, Willie, and the aura of postmodernity, again dispels Jacks attempts by literally absorbing the gunshot in his gut. Jack, overcome with disappointment and frustrated in the face of the inevitability of defeating Willie, then recognizes the fundamental impossibility of bridging the gap between subject and object, between modernism and postmodernism, between himself and the new world. Instantly, Jack, for the first time in the novel, sees the world as it truly is The extra dimensions, the super perceptions, were reduced to visual clutter, a whirling miscellany, meaningless (313).Ultimately, Jack learns that the most important aspect of existence is be ing able to step back from the cultural frays of modernism and postmodernism, of subject and object, of reflection and criticism and certainty, in order to understand the rationality which gave rise to them in the first place. When one exists outside the realms of either movement, as Jack does at the end of White Noise, the beauty of being reveals itself in the mysteries of not knowing what comes next, what came before, or what forces drive our existence.Certainly there is awe, it is all awe, it transcends previous categories of awe, but we dont know whether we are watching in wonder or dread, we dont know what we are watching or what it means, we dont know whether it is permanent, a level of experience to which we will step by step adjust, into which our uncertainty will eventually be absorbed, or just some atmospheric weirdness, soon to pass.

Garlic And Abate As Larvicide Against Mosquito Larvae Biology Essay

Garlic And decrease As Larvicide Against Mosquito Larvae Biology EssayThis experiment was designed to investigate and compare the effectiveness of ail as the subjective larvicide and quench as the chemical larvicide against mosquito larvae. The effectiveness of the larvicides was determined by the succession taken for wholly the mosquito larvae to be killed. The mosquito larvae were placed in break in flexible transfuses containing ail press and quench respectively. They were monitored at fixed judgment of conviction intervals and the m taken for all the mosquito larvae to die was recorded. The experiment was repeated with different concentrations of ail extract and slack off. A two-way ANOVA statistical test showed that decrease is more effective against mosquito larvae at 5% significance level compared to garlic, corresponding to the experimental hypothesis.Research and RationaleMosquitoes originate from the family Culicidae.13 Like many other insects, they go throu gh a life cycle from egg to larva, pupa and finally adult. They are largely well-known as blood-sucking insects to kind and they are responsible for many fatal diseases such as dengue, malaria and yellow fever. Some unremarkably known genera are Aedes, genus Culex and Anopheles. Usually, mosquitoes breed in stagnant pee like ponds, marshes and swamps and they thrive in warm climates.9(210 words)In order to control mosquitoes, chemical larvicides are apply. One commonly used larvicide, Abate is applied to stagnant water to kill larvae of a wide range of pathogen-carrying vectors (mosquitoes) to hinder their development into adult mosquitoes.2 Consequently, this prevents disease-carrying mosquitoes from hatching and transmitting the pathogens to human via bites. Although the active ingredient of Abate, temephos is said to be effective against mosquito larvae (affects the nervous system by inhibiting cholinesterase enzyme), it has its downsides.Research has shown that certain mosq uito species (Aedes albopictus and Aedes aegypti) have developed resistance for Abate.4 In addition, rats exposed to temephus showed organic phosphorus poisoning while some fish are vulnerable to temephus. Temephus also harm inverterbates such as shrimps and crabs. Accumulation of temephus may also cause drastic impacts on cholinesterase activity involved in nerve signal transmission.6Plant extracts such as those of garlic are latent alternatives to Abate. Crushing garlic releases thiosulfinates which convert into diallyl disulfide and diallyl trisulfide if mixed with water.10 These two products formed are effective against mosquito larvae. Trials conducted in Bombay have shown that several species of mosquito larvae are susceptible to garlic extracts. Allicin helps to restrain malaria by preventing the formation of circumsporozoite protein (CSP) of Plasmodium sporozoites to infect host cells.10 They are effective, safe, environmental-friendly and economical.The objective of this experiment was to investigate and compare the effectiveness of garlic as the natural larvicide and Abate as the chemical larvicide against mosquito larvae. The results from this experiment indicate that the spread of pathogen-ca development diseases by mosquitoes can be curbed by using natural substances such as garlic as well as chemical larvicide like Abate. Garlic is a potential alternative to Abate as it is effective, easily available and eco-friendly. Although it talent non be as fast-acting as chemical larvicides, garlic has none of the downsides of Abate such as accumulating in the environment and killing other invertebrates. Thus, more research is world conducted to investigate the efficiency of garlic as a larvicide.(545 words)Experimental hypothesisThere is a significant difference amid the effectiveness of garlic and Abate as larvicide. Abate is more effective larvicide compared to garlic.Null hypothesisThere is no significant difference amidst the effectiveness of garlic and Abate as larvicide.VariablesManipulated variable Types of substancesResponding variable Time taken for all the larvae to dieFixed variables Number of mosquito larvae, volume of distilled water, roomtemperatureApparatus cmL measuring cylinder, electronic balance, plastic cups, tick off stickers, pestle and mortar, disposable droppers, glass rodMaterialsMosquito larvae, garlic cloves, cinnamon powder, fennel powder, Abate 1.1G, distilled waterPlanningA trial experiment was conducted to determine which natural substance has the most significant effect on mosquito larvae. The three natural substances used were cinnamon powder, fennel power and garlic cloves. Three labelled plastic cups were used. About 1% of each respective natural substance extracts were made by either dissolving 1g of the powder in 100mL of distilled water or power hammer 1g of garlic and then mix with 100mL distilled water. Using a disposable dropper, 5 mosquito larvae were inserted into each cup and they were allowed to sit for 24 hours. The round of mosquito larvae unexpended after 24 hours was counted.(750 words)Types of natural substancesNumber of mosquito larvae left after 24 hoursCinnamon3Fennel5Garlic0Table 1 Number of mosquito larvae left after 24 hours with respect to natural substancesThe results imply that garlic showed the most significant effect on mosquito larvae since none of the mosquito larvae was left after 24 hours.A second trial was carried out to determine the method to amount of money the effectiveness of garlic and Abate. The first method was to count the number of mosquito larvae left after 24 hours while the second was to measure the time taken for all larvae to die. Three concentrations were used for each substance and method.SubstanceNumber of mosquito larvae left after 24 hours for each concentration1%2%3%Garlic000Abate000Table 2 Calculating the number of mosquito larvae left after 24 hoursSubstanceTime taken for all larvae to die for each concentr ation (minutes)1%2%3%Garlic420360120Abate907555Table 3 Measuring the time taken for all larvae to dieThe results showed that method 1 was non practical to use since no mosquito larvae is left after 24 hours for both garlic and Abate. Therefore, method 2, which is to measure the time taken for all larvae to die, was used to compare the effectiveness of both substances as larvicides.(983 words)Real Experimental Procedures1g of garlic clove was weighed using an electronic balance.The garlic clove was placed in a mortar and it was pounded lightly using the pestle to obtain garlic extract.100mL distilled water was measured using a measuring cylinder and it was poured into the mortar to form an extract solution of concentration 1%.The solution was then transferred into a labelled plastic cup.Using a disposable dropper, five mosquito larvae were transferred into the beaker.At 5-minutes interval, the number of breathless mosquito larvae in the beaker was counted and recorded to measure th e time taken for all larvae to die. Dead larvae are those that cannot be induced to move when they are touched with the tip of the dropper. go 1 to 6 are repeated twice to obtain an average time taken.Steps 1 to 7 are repeated for garlic cloves of 2g, 3g 4g and 5g.The time taken for all larvae to die for each respective garlic concentration was tabulated.Steps 1 to 9 were repeated using 1g, 2g, 3g, 4g and 5g of Abate 1.1.A graphical record of mean time taken for all larvae to die against concentration of larvicides was plotted.A two-way ANOVA test was used to analyse the data statistically.Risk legal opinionThe experimental procedure is ranked low-risk. The risk of accidental introduction of mosquito into the environment had been considered and precautions were taken to ensure that pupae which had developed into mosquitoes were not released, but killed in the water. The container containing larvae were closed at all time. Gloves were worn to avoid direct contact with Abate which i s toxic. Hands were washed before and after handling garlic extract, Abate and mosquito larvae. After using droppers, they were disposed properly. When the experiment had completed, the solution containing dead mosquito larvae were drained into the science laboratory sink.(1307 words)ResultsConcentrations (%)Time taken for all mosquito larvae to die (minutes)GarlicAbate1.1G123 miserly123Mean1360345370358.390859088.32300310300303.375757073.33120115120118.355506055.0410090110100.045404041.7580807076.730353533.3Table 4 Time taken for all larvae to die for different concentrations of garlic and Abate material body 1 Graph of mean time taken for mosquito larvae to die with respect to concentrations of larvicides(1409 words)Statistical AnalysisTwo-way ANOVA test was used to analyse the data to show whether there is a significant difference between the two larvicides. The Columns P-Value (8.58E-24) is less than the significance level ( = 0.05). There is a significance difference between the larvicidal properties of Abate and garlic. Abate is a stronger larvicide than garlic. Therefore, the experimental hypothesis is accepted and the null hypothesis is rejected.From the analysis also, the calculated Sample P-value (3.62E-22) is less than the significance level well-tried as well ( = 0.05). This shows that there are statistically significant differences between different concentrations of garlic and Abate. The Interaction P-Value (3.01E-19) indicates that there was a statistical significant interaction between the larvicides and the concentrations used. Higher concentrations of both larvicides are more effective against the mosquito larvae compared to lower concentrations.(1548 words)SubstancesGarlicAbateTotal0.01Count336 tote up10752651340 second-rate358.333388.33333223.3333Variance158.33338.33333321936.670.02Count336Sum9102201130Average303.333373.33333188.3333Variance33.333338.33333315886.670.03Count336Sum355clxv520Average118.33335586.66667Variance8.333333251216. 6670.04Count336Sum300125425Average10041.6666770.83333Variance1008.3333331064.1670.05Count336Sum230100330Average76.6666733.3333355Variance33.333338.333333580TotalCount1515Sum2870875Average191.333358.33333Variance14458.81445.2381Table 5 Summary of the data(1656 words)Source of VariationSSdfMSFP-valueF critSample137903.3434475.83880.2343.62E-222.866081Columns132667.51132667.53387.2558.58E-244.351243Interaction69970417492.5446.6173.01E-192.866081Within783.33332039.16667Total341324.229Table 6 Calculations for two-way Anova test(1701 words)Data AnalysisThe two-way ANOVA test revealed that Abate is a stronger larvicide than garlic. The Columns P-value is less than the significance value ( = 0.05), which indicated that Abate and garlic are significantly different in terms of larvicidal properties. This supports the experimental hypothesis that the effectiveness of Abate is greater than that of garlic.Table 4 shows that for all Abate concentrations, the mean time taken for all the mosquito l arvae to die are shorter compared to that of garlic. For both larvicides, as their concentrations profitd, the mean time decreased. From the data in Table 4, it can be evaluated that there is a bigger percentage difference in the mean time taken between garlic and Abate for the first two concentrations (about 75%). For 3%, 4% and 5% concentrations, the percentage differences in mean time range from 54% to 58%. This is illustrated in Figure 1. It clearly suggested that Abate is much more effective than garlic.Abate is a chemical larvicide while garlic is a natural larvicide. both(prenominal) contain the active substances which are capable to kill mosquito larvae. Within 24 hours, all mosquito larvae would have died in Abate as well as garlic solutions. It was therefore not practical to calculate the number of live mosquito larvae after 24 hours. Hence, the time taken for the mosquito larvae to die was used as a measure of the substances effectiveness. The shorter the time taken, th e more effective the compound is. Dead larvae can be identified by touching them with the tip of a rod or dropper. They cannot be induced to move.Abate contains temephos which is an organophosphate compound.11 It is able to inhibit acetylcholinesterase enzyme which is required to stop a nerve impulse after it has crossed the synapse. As a result, there is a continuous stimulation of the nerve, resulting in tremors and uncoordinated movement.11 Garlic, when crushed and mixed with water, will convert thiosulfinates to diallyl disulfide and diallyl trisulfide,10 both which are organosulfur compounds. They are effective against mosquito larvae.(2043 words)The experiment showed that Abate is a more effective larvicide compared to garlic. Both organophosphorus and organosulfur compounds worked against mosquito larvae. This explains that during the trial experiment, after allowing both solutions to sit for 24 hours, all mosquito larvae died. Nevertheless, the experimental results showed th at Abate which contains organophosphorus compounds took a shorter time to kill all the mosquito larvae compared to garlic (organosulfur compound), implying that organophosphorus compounds are more effective against mosquito larvae. However, this may also be due to the purity of the active substances. The industrially-produced Abate contain pure temephos, whereas allicin found in garlic is impure. For an active ingredient to work effectively, it has to be extracted and processed to give optimum results.Although results showed that Abate is a more effective larvicide, it should be noted that Abate is harmful to certain animals such as mice and fish, as well as to some invertebrates. Abate is also liable to accumulate within the natural environment, pose risks to human health. Garlic is an option to replace Abate as it is easily obtainable, cheap and does not pose harm to the environment. Nevertheless, garlic takes a longer time to kill mosquito larvae compared to Abate. Time is a cru cial factor when dealing with disease-carrying mosquitoes such as Aedes aegypti. Therefore, although garlic might be effective against mosquito larvae, it may not be practical to use such a time-consuming substance to alleviate the problem with mosquito larvae.(2287 words)EvaluationTo increase the accuracy, the base of the garlic, together with its skin was distant before the garlic cloves were weighed using an electronic balance. The garlic cloves were pounded lightly using a mortar and pestle to prevent heat from destroying the chemical contents of garlic, which might decrease the effectiveness of garlic. Disposable droppers were used to avoid contamination of substances being tested and in the container used to collect mosquito larvae. Besides, plastic cups were used instead of laboratory glassware in order to prevent contamination as well. Each cup was closed with a perforated cover to ensure that air flows into the cup. The cup was cover as a precaution to prevent the introduc tion of any mosquito into the environment in case any larvae managed to complete its life cycle.Results from the trials showed that all mosquito larvae were killed by the larvicides within 24 hours. Therefore, if the number of live mosquito larvae were noted after 24 hours, there would not be any significant differences. As an alternative, the time taken for the mosquito larvae to be killed was measured. It was also impossible to run a stopwatch to measure the time as it would be difficult to estimate when to stop it. Instead, the mosquito larvae were observed every five minutes and any dead larva was noted. Hence, the time measured was estimation as it would be hard to check on the larvae every minute for hours. To increase the precision of results, the experiment was repeated twice to obtain an average time.It was also impossible to differentiate the types of mosquito larvae. Different larvae species might have different response towards larvicide. However, in this experiment, the y were assumed to be of the same species. The larvae were also of different days old. Larvicides might have different set up on larvae of different days old. Besides, the solutions might not contain the exact concentration which was supposed to be tested. This is because garlic juice might not be able to be extracted and dissolve in distilled water completely. Abate granules also did not dissolve completely in distilled water.(2641 words)An ethical issue that may be questioned is the accidental introduction of mosquitoes into the environment. In this experiment, mosquito larvae are stack away from ponds, which are mosquito breeding grounds. These mosquito larvae are actually prevented from turning into adult mosquitoes, which may transmit certain diseases. Larvae collected are placed in a covered container and are monitored to prevent accidental introduction of mosquitoes in case any larva managed to complete its life cycle.This investigation could be modified by grinding the garl ic cloves and dissolve it in ethanol to form garlic solution of a particular concentration. This would increase the reliability of the results. Besides, mosquito larvae of the same species could be used to ensure that the effects of larvicides on that particular type of mosquito larvae only are determined. This reduces the probability of results occurring by chance. Mosquito larvae of a specific species could be cultured rather than collecting them from a pond. The number of mosquito larvae could also have been increased to obtain a more reliable result.ConclusionChemical larvicide, Abate is significantly more effective than garlic in killing mosquito larvae. This was determined by the notably shorter time taken by Abate to kill all the mosquito larvae than shown by garlic.(2848 words)Source EvaluationSource 2 contains information on agricultural products such as vector control by BASF, the worlds leading chemical company and a corporate group.
