Caroline Herschel (Astronomer and Mathematician)

Caroline Herschel (Astronomer and Mathematician) Dates: March 16, 1750 - January 9, 1848 Known for: first woman to discover a comet; helping discover the planet UranusOccupation: Mathematician, astronomerAlso known as: Caroline Lucretia Herschel Background, Family: Father: Isaac Herschel, court musician and amateur astronomerSiblings included: William Herschel, musician and astronomer Education: educated at home in Germany; studied music in England; taught mathematics and astronomy by her brother, William About Caroline Herschel: Born in Hanover, Germany, Caroline Herschel gave up on getting married after a bout with typhus left her growth stunted seriously. She was well-educated beyond traditional womens work, and trained as a singer, but she choose to move to England to join her brother, William Herschel, then an orchestra leader with a hobby in astronomy. In England Caroline Herschel began assisting William with his astronomical work, while she trained to become a professional singer, and began to appear as a soloist. She also learned mathematics from William, and began helping him with his astronomy work, including grinding and polishing mirrors, and copying his records. Her brother William discovered the planet Uranus, and credited Caroline for her help in this discovery. After this discovery, King George III appointed William as court astronomer, with a paid stipend. Caroline Herschel abandoned her singing career for astronomy. She helped her brother with calculations and paperwork, and also made her own observations. Caroline Herschel discovered new nebulae in 1783: Andromeda and Cetus and later that year, 14 more nebulae. With a new telescope, a gift from her brother, she then discovered a comet, making her the first woman known to have done so. She went on to discover seven more comets. King George III heard of her discoveries and added a stipend of 50 pounds annually, paid to Caroline. She thus became the first woman in England with a paid government appointment. William married in 1788, and though Caroline at first was skeptical of having a place in the new home, she and her sister-in-law became friends, and Caroline had more time for astronomy with another woman in the house to do the domestic chores. She later published her own work cataloguing stars and nebulae. She indexed and organized a catalogue by John Flamsteed, and she worked with John Herschel, Williams son, to publish a catalog of nebulae. After Willliams death in 1822, Caroline had to return to Germany, where she continued writing. She was recognized for her contributions by the King of Prussia when she was 96, and Caroline Herschel died at 97. Caroline Herschel was, along with Mary Somerville, appointed to honorary membership in the Royal Society in 1835, the first women to be so honored.

Buddhism Essay Example | Topics and Well Written Essays - 1000 words

Buddhism - Essay Example Buddhism is one such religion. It is a religious practice that recognize and appreciates the reasonable teaching that emanate from every other religion (Harvey 19). Moreover, it tolerates the customs of other religions and cultural practices that might not be able to appreciate their teaching of Buddhists in return. Buddhism In essence, Buddhists are in a position to respect the views of man and appreciate other practices without harboring any religious prejudices. Buddhists, who are not able to appreciate the ways of other religious practices, maintain their silence and refrain from confrontations of any kind thus ensuring that is peaceful co-existence through sympathetic understanding (Harvey 23). Buddhism commenced as a reform group in Hinduism; India in the sixth century B.C (Eliot, 20). It was one of the ancient religions to emerge to become international having a membership of over two hundred thousand people. It was founded by Siddhartha Gautama, who was a son of the ruler of the Kshatriya caste (Eliot, 22). Gautama left his family and went out to seek enlightenment concerning the sufferings and anxiety of a decrepit man that he had witnessed in outside the royal compound. After seven weeks, he received the Enlightenment, hence became Buddha-the enlightened one. The Buddhists emphasize on practicing a religion that is honest, sincere, and truthful and that which is kind to others. They do not try to justify war under any circumstances rather they believe in solving a problem in a more considerable way while ensuring that they are not irritated or angered by people not paying attention to them (Skilton 24). In fact, they argue that, the attitude of a real religion; the Buddhism is to advice people instead of ruling or intimidating them. According to Buddha, human beings are not cruel or wicked by nature rather they make mistakes and act as cruel as people due to their ignorance. Hence the importance of guiding them in the right path, as opposed to condemn ing them to external suffering or religious damnation. They point out the vainness of certain religious beliefs and practices but at the same time preach religious intolerance. Needles to say, Buddhism has also been able to incorporate religious practices and customs from other religions, which have refined them in the course of their expansion (Skilton 26). Buddhism as a reform religion In relation to this, I agree to the fact that Buddhism is a reform religion. This is because Buddha who was associated with the Buddhism, lived a life that was sustainably different he considered himself as one who revolutionized the religious way of life in a more dignified manner. Although he was condemned, criticized and insulted by most noted teachers and critics, there is no doubt that Buddha reformed certain customs, duties pertaining to religion, rites, ethics and the general way of life. Essentially, his outstanding character cut across the buckets of false beliefs and practices that were pr esent in the religion leading to the exposure of the fact that they lacked content (Harvey 27). In particular, he brought up the idea of Nibbana, the Eightfold Path and the Four Noble Truths. And even though they believes were common per say, he gave rational and realistic explanations to support his argument and initiated it as a natural law of cause and effect. Further more, he appreciated the value of the many he come across especially those that related to the Truth hand even offered an explanation of their

Bacons Rebellion Essay Example | Topics and Well Written Essays - 750 words

Bacons Rebellion - Essay Example This reality struck the manipulative white class which controlled the disadvantaged class. As is shown in the picture below, whites and blacks are together preoccupied by a mission, however offensive it may be. The picture shows white Virginia settlers and amidst them there are also black men. The man on extreme right beating the drum is a black rebel who like other men in the picture is provoked by Bacon to set Jamestown on fire. The supporters Bacon gathered around himself to thwart Berkeley for personal reasons were a mix of whites and blacks. The image above also shows that Bacon, though leading the rebellion for personal motives, unconsciously demonstrated to the ruling white class that poor whites and blacks could be unified for a solid cause. The whites and blacks who would never stand close to one another struck up an alliance which sent out a very clear message to the rich Virginia colonists. There is a message of unity emanating from this picture and this message frightened the rich white class. This unity between poor white and black social groups motivated the ruling elites to turn whites against black servants by inculcating a sense of racial hatred in them. This also motivated them to incapacitate poor blacks by the aid of slavery. It was due to this alliance between whites and blacks in the Bacon’s rebellion that the rich white planters set out on creating distances between them by very strategically extending more benefits to the disadvantaged whites. Giant masses of Negro slaves and white servants bonded during the course of Bacon’s rebellion. They allied against rich whites of Virginia because Bacon promised them equal rights and independence from economic contraction. It is not a general consensus that Bacon only instigated this rebellion for personal benefits (Rothbard 2012). Bacon might have had some good reasons too to start a rebellion on such a large scale as was believed by a large number of whites and

ESSAY PROMPT Example | Topics and Well Written Essays - 1250 words

PROMPT - Essay Example If we talk about Hamlet, we can’t but mention that suicide represents a continuous theme in the tragedy. During the play Hamlet considers suicide many times, his thinking about the life and its essence, about the troubles of real life and the fascination of unconsciousness is famous all over the world as remains unique. The given paper will discuss two famous soliloquies of Hamlet, in which he is talking about death and prove that Hamlet does not really want and was going to die. Hamlet is naive and passionate, not suicidal. Evidence: Soliloquy in Act I When we get acquainted with Hamlet, his first soliloquy in Act I reveals his nature. We see a passionate and vulnerable guy who is extremely astounded by his father’s death. He is almost a child and can’t help crying and wishing to die to be with his beloved father. It is very difficult to lose parents, especially when you are still young. Moreover, Hamlet has one more reason to be so upset: his beloved mother doe s not share his sorrow. Instead she is celebrating her wedding with Hamlet’s uncle Claudius. A young person, who still considers love to be a sacred thing is shocked with such an indifference. The pain is stronger because he knows what love is himself – and we remember about Hamlet’s feeling to Ophelia. Hamlet knows what love is, thus he is extremely astounded by the events as he considered his father’s marriage to be happy. ... The father is dead and the mother is married to another man, thus she does not share the son’s sorrow about the death of his father. These thoughts of suicide are not true, they are the results of the young guy’s despair. Hamlet’s soul is beautiful and he was sure that the souls of other people, especially his own mother’s soul was also pure and beautiful. But now he calls his mother: â€Å"an unweeded garden that grows to seed.† (1.2.139). He considered his mother to be sacred but suddenly became a witness of her fall. He is full of negative emotions, thus he thinks about death like many other people in such state. Hamlet is also religious. He perfectly understands that death is a sin, thus he should not even think about it. He feels bad but would never commit suicide at that moment as he believes in â€Å"Everlasting† (1.2.135). In the Act 1 Hamlet still believes that the God would save him and would not let him die. Here we see Hamlet as s till young, naive and sentimental creature who cries about the love between his parents, which he considered to be true, but now he has to change his mind because of the mother’s very fast marriage. Having high moral principles and believing in God, Hamlet suffers recollecting his mother’s â€Å"unrighteous tears† (1.2.159) caused by the father’s death, the tears, which he considered to be true. â€Å"To be or not to be† does not mean â€Å"to live or not to live†. Evidence: Soliloquy in Act III In the Act 3 we already see Hamlet from another side and this makes us understand that everything he said and was thinking about in Act 1 was just childish melancholy. Hamlet also understands this and this is what his most famous soliloquy is focused on. After his conversation with the ghost he suddenly

Factors Contributing to Obesity and Diabetes among Americans

Factors Contributing to Obesity and Diabetes among Americans Obesity is a condition that emanates from malnutrition and presents with serious social and psychological problems. It is present across different ages and affects individuals in the developing and developed countries. Aiko and Sturm (845-856) writes that obesity has turned into one of the most serious global epidemics as it spreads, to many parts of the globe affecting millions of healthy lives each day. The most shocking revelation is that obesity epidemic is not only affecting developed nations. From studies this condition continues to affect even the individuals in the developing world. This essay aims at discussing some of the views of Aiko and Sturm who authored an article dubbed â€Å"The obesity epidemic and changes in self-report biases in BMI.† on obesity epidemic and how self-report biases have increased the trends in obesity cases across the globe. This essay will also cite the research gaps that the authors did not include in their study. According to World Health Organisation (WHO), the obesity epidemic remains one of the ignored public health problems that affect millions of individuals across the globe. In a forecast, WHO predicts that without proper public health initiatives, obesity epidemic will affect many people globally and lead to aggressive health complications. According to WHO, this condition is mainly affecting women as compared to men. Nonetheless, the author notes that many men have higher cases of overweight while women have higher cases of obesity. What the article fails to mention is the cases of obesity among children. Children who had developed obesity in the US and other major cities tend to place the blame on the food sellers such as McDonald. The author reiterates that while many people blame the eater (children), the blame should be made on the food makers. I agree with the author on the fact that many children who are trying to get affordable foods often end up feeding on unhealthy fast foods. Such foods as stated by Aiko and Sturm (855) should not be taken more than once in a single day. However, the author notes how he had to eat fast foods repeatedly since it was the only option for affordable food. This article explains that there are many cases of diabetes because the fast food industry has grown ten-fold t offer children as well as adults cheaper and easier alternative to affordable foods. Nevertheless, many people working in the restaurants have not realised the dangers that they expose their customers to. I also agree with the fact that ignorance among individuals has contributed to obesity epidemic. While many people yearn for sumptuous foods sold in McDonald, Taco, and KFC, a few understand the risks of obesity that they are exposed to. The fact that Food and Drug Administration does not cover prepared foods, there is little information concerning the caloric contents of such foods. Additionally, I also contend with the claim that marketing of hazardous fast foods to children is to blame for the heightened rates of obesity among the children. As many fast food companies continue to grow, many children find access to such foods regularly. This has led to unprecedented levels of risks of developing obesity. In this manner, the claim by the author that food sellers are to be blamed for the obesity epidemic. However, the author did not mention the possible effects of sedentary lifestyle and other risk factors such as family history of obesity and lack of warning labels on high-calorie foods. On the other hand, there are many initiatives that had been introduced in the US such as funding for new bike trails and sidewalks, restrictive labelling of foods and prohibiting marketing of dangerous foods to children. According to the article, such initiatives have the ability of reducing the cases of obesity among school children. High tax for high-fat foods aimed at reducing the production and sale of foods known to cause obesity among the children. According to Gotay et al. (e64-e68), such initiatives are wrought and irrelevant. Balko (Para.3) objects such moves on the basis that they limit the ownership of one’s control of health. The author says that if such regulations are enforced, then certain individuals are forced to be responsible for other people’s problems. I contend with the claim that individuals have become irresponsible for their own health. While people are supposed to care about their health, many individuals continue to blame the Federal Government on healthcare management. While many consumers continue to develop bad habits, obesity epidemic continues to rise. I also contend that whatever we eat is our own business. While there are many people who think that public health can resolve the issue of obesity, I concur with the writer that our health is a private issue and should not belong to the public health. For instance, Aiko and Sturm (856-860) note that fighting the obesity epidemic starts by change of lifestyle, nutrition as well as physical exercise. These preventive measures are often done privately and not with the help of the government or the public health. However, I disagree with the author on account that healthcare should be privatized. While the government spends millions of shillings in facilitating preventive proj ects, Dietz (575-596) acknowledge that many people may not be able to afford such initiatives. The cost of health is very high, as such; public health programs aim at initiating preventive measures that target the reduction of diseases and epidemics. It is true that the contemporary methods of measuring obesity among various populations. The article dubbed, â€Å"The Obesity Epidemics and the changes in the Self-reported biases in BMI,† gives a clear insight of how cases of obesity are not fully discovered among individuals. Idyllically, such cases may remain obscure for a longer period of time without the knowledge of the public health officials. I agree with the author that biases subject to social desirability as well as recall errors have led to poor reporting of obesity cases in many countries. As such, this event has facilitated increased cases of obesity leading to unimaginable obesity epidemic. The author notes that BMI measurement error leads to underestimation of the BMI that can be used to determine the case of obesity among individuals. I also contend with Aiko and Sturm on the fact that media coverage on the cases of obesity has uncovered the lack of awareness among individuals and their weights. According to Aiko and Sturm (4), poor reporting of BMI is one of the faults that ostensibly cause lack of awareness on obesity and related disorders. However, the media has played an imminent role that has transformed lives of many individuals by exposing the disparities in BMI self-reports and the actual BMI reports. While the bias in self-reporting has been cited as one of the reasons why obesity is growing rapidly in the US, Aiko and Sturm (3) note that measuring of the BMI should include the detailed analyses that will minimise the errors that occur during measurement of the procedures. While the media has been proactive in raising obesity awareness in the recent times, Aiko and Sturm (5) note that the problem of error in self-reporting has led to poor accuracy in estimating the number of individuals who suffer from obesity. To this end, acknowledge that there are possibilities of the obesity epidemic becoming out of control. Individuals only continue to gain weight when there are no weight reduction initiatives. As such, it is important to institute proper weight and height measuring techniques that ensure accuracy in reporting the BMIs of individuals. The BMI measurement remains the commonest way of determining whether an individual is obese or not. In this manner, it is imperative as stated by Aiko and Sturm (5) to use techniques that teach individual populations on the obesity epidemic. On the contrary, I disagree with the claims of the author that the outburst of obesity epidemic is due to errors in measuring the BMI among individuals. Ideally, there are many factors that have changed over time concerning how individuals view healthy choices. Awareness on the obesity issues help in adopting preventive measures that help many individuals in preventing obesity. In this manner, the author should have included lack of information as one of the main facilitators of obesity. A mixture of factors leads to the development of obesity. In this manner, note that erroneous measurement of the BMI can only be counted as a secondary factor in the development of obesity epidemic. The American Heart Association indicates that many Americans are dealing with complications of obesity in the United States. This is a confirmation that this condition has become a major epidemic. Individuals have chosen unhealthy lifestyles that continue to facilitate the development of the epidemic. With the increased trends in technology, sedentary lifestyles have replaced the manual techniques that ensured physical activities among individuals. On the other side, resisting food cues has been a major problem among many individuals suffering from weight problems. As such, there is a major problem in dealing with nutrition and lifestyle than dealing with BMI measurement errors. However, Aiko and Sturm (4) are also right since raising awareness on obesity can help people in remaining fully aware and capable of regulating risks that can initiate the development of obesity. To this end, it is evident that obesity epidemic is dependent on variant factors that should be considered while preventing the condition. Works Cited Dietz, William.

Integration and Animal Farm by Orwell :: Free Essay Writer

Integration and Animal Farm by Orwell Integration of Education in the United States Throughout history, education is recognized as one of the key components of any civilized society. It is a natural instinct for man to learn, and feel the need to pass on that knowledge to their young and to all those who come behind them. People have a passion for education, and will fight for the opportunity to gain the valuable knowledge that education provides. The importance of education in a society is illustrated in two aspects. The first being the actual events in American history regarding the desegregation of schools, and the second being the action of the animals in George Orwell's Animal Farm upon receiving their liberation on Manor Farm. In recent times we have witnessed a struggle in American society for the opportunity of minorities to realize the education that their white counterparts received. It began with slavery, when blacks were prohibited from obtaining even the basic skills to read and write. When blacks were finally allowed this liberty, we began our own makeshift schools, and were content with this opportunity. As time progressed, and more formal schools were established, minorities realized that they were not receiving the same quality education as those of the majority. This sparked a legal battle that lasted over fifty years. The first landmark was the case of Plessy v. Ferguson in 1896. It established the doctrine of "separate but equal." This concept stated that separate public facilities of equal quality do not violate the equal protection clause of the Fourteenth Amendment of the Constitution. This amendment says that no state may "abridge" the privileges of any citizen, nor may any stat e deprive any citizen of life, liberty, or property without due process of the law. In 1954, fifty-eight years later, the Case of Brown v. the Board of Education of Topeka finally settled the debate of whether or not blacks and whites can receive an education integrated with or separate from each other. This time the Supreme Court unanimously ruled to overturn the Plessy v. Ferguson decision. In his opinion, the Chief Justice wrote, "We conclude that, in the field of public education, the doctrine of "separate but equal" has no place. Separate educational facilities are inherently unequal." The Brown case signaled the end of segregation of public places mandated by law.

Behaviour of Studied Plant Species in Terms of Heating Mitigation and Evapotranspiration

5 Discussion5.1 Weather ConditionssUpwind conditions during the season and the six measuring runs played a cardinal function for the procedure of this survey. As mentioned antecedently in respects to the survey of thermic imagination and specific conditions conditions were a requirement. The optimum conditions conditions for transporting out these measurings included clear sky, no air current and high values of PAR. These conditions slightly restricted the measurings as they were hard to be obtained for many yearss during the months from May until July. The measurement period was characterized by many yearss of cloud screen, rainfall and low temperatures and merely a few yearss of clear sky and high temperatures every bit good as high PAR values. The most restrictive factor was the cloud screen, as there were yearss with high temperature and besides there was cloud screen. However, there were yearss with clear sky and no air current but the PAR values were excessively low ( below 120 0 ?mol s-1m-2) , so that measurings could non be performed. Besides, it is of import to observe that the conditions conditions differed for each of the measuring dates as it was impossible to hold the exact same conditions every clip. Maes and Steppe ( 2012 ) had highlighted the limitation of conditions conditions in thermic imagination and the confining factor of cloud screen. However the consequences of the six successful measuring day of the months led to observations and decisions about the thermic behavior of the five studied works species.5.2 Behaviour of Studied Plant Species in Footings of Heating Mitigation and EvapotranspirationThe current survey have shown that all of the tried workss species had an effectual chilling potency by comparing to the bare dirt. Planted trays had ever lower surface temperatures than the control trays. This was besides supported by the statistical analysis which indicated important differences between mesocosms and control trays. Several surveies stated that one of the benefits of green roof workss is to maintain the temperature low ( Nagase and Dunnett, 2010 ; Teemusk and Mander, 2009 ) . Specifically, the four of the five species,Koeleria glauca, Lotus corniculatus,Dianthus carthusianorumandPhedimus floriferumhave been shown to hold lower temperatures than the controls trays for the full period of when the measurings were conducted. However, in the last two day of the months sing the measurings, theThymus serpyllumhad showed higher temperatures than the controls trays because the mini bush had died antecedently. While all workss of the monocultures had died many single species were able to last in combination with other species. However,Thymus serpyllumis considered a common green roof species ( Teemusk and Mander, 2009 ) . Besides, Jones ( 2002 ) had indicated thatThymusspecies frequently did non last. The ground for the bad public presentation ofThymusis still non clear. Although heat and drouth emphasis are known to hold a negative impact on the species, it is besides believed that works infections could be another cause for its bad public presentation. Sing the evapotranspiration, all the mesocosm systems showed to hold higher values than the control trays. System 5 (Phedimus floriferum )showed to hold the lowest evapotranspiration of the 15 mesocosms due to the facultative CAM metamorphosis of the species. The last two yearss System 4 showed the lowest evapotranspiration values sinceThymus serpyllumin the monocultures where they had wholly died off. Several surveies have been conducted to compare between green roof works species in monocultures and combinations in order to transport out and understand in which of the two is the most good. The surveies concluded that works mixtures were more effectual and good in footings of heating extenuation, evapotranspiration and H2O gaining control than monocultures and recommended for extended green roofs ( Lundholmet al. ,2010 ; Nagase and Dunnett, 2012, 2010 ) . This survey had concluded that System 7 a combination ofPhedimus floriferum( succulent ) andLotus corniculatus( leguminous plant ) was more effectual and good along with System 10 which is a combination ofPhedimus floriferum( succulent ) ,Koeleria glauca( grass ) andDianthus carthusianorum( herb)and can be considered as the best of the 15 systems in footings of extenuating warming effects. These systems showed significantly lower temperatures during most of the measurings. Systems 6( Phedimus floriferum + Koeleria glauca )and 14 (Phedimus floriferum + Koeleria glauca +Lotus corniculatus )had so followed with satisfactory consequences. These consequences are in general conformity with other surveies which showed that grass and herb or mixtures of these species are really suited to green roofs. Although they are less drought tolerant than succulent they are more effectual in footings of evapotranspiration and H2O keeping capacity ( Van Mechelenet Al., 2014 ) . Besides, the bulk of green roofs in North America and Europe are combinations of Sedum species or combinations of Sedum and grasses ( Wolf and Lundholm, 2008 ) . Lundholmet al. ,( 2010 ) had stated that the best combination for green roof is succulents, grasses and tall forbs. Since thei experiment this works mixture optimized most of the maps which were measured. Koeleria glaucacan maintain the H2O balance stable alternatively of intensive transpiration. Besides, its foliages are sclerenchymatous and about lush at the same time ( Kalapos T.,1989 ) . Furthermore, many herbaceous species are characterized by adaptative steps and could confront drouth ( Dvorak and Volder, 2010 ) . Some adaptative steps for Sedum species and stress-tolerant grasses and herbaceous are CAM photosynthetic tracts, H2O storage variety meats, succulent foliages which characterized the Sedum species, drought-avoidance ( bulbs and ruderals ) and woody growing. These and other morphological and anatomical characteristics could cut down the heat addition and H2O loss ( Wolf and Lundholm, 2008 ) . Grasss and forbs are characterized by low root H2O electrical capacity and/or drouth turning away which allow them to last in green roof systems ( Wolf and Lundholm, 2008 ) . It is besides deserving observing the importance in respects to the monocultures ofKoeleria glaucaandLotus corniculatusholding shown really good warming extenuation and chilling effects consequences. Besides combinations which included these species proofed to be really suitable. These species are both characterized by holding high evapotranspiration values andLotus corniculatusbesides being good of making high works screen due to strong vegetive growing. In respects to the Sedum speciesPhedimus floriferum,it is confirmed that it is really good for green roofs. Although it was frequently hotter than the other species likely due to its CAM metamorphosis it had a positive consequence on the other species.Phedimus floriferumwas presented with combinations which showed the best heat emphasis extenuation and kept the temperatures at low degrees during the measurement period. Several surveies investigatedSedumspecies as they are the most normally used for extended green roofs. Most of the surveies concluded thatSedumspecies can be characterized as ideal species and the best option for green roofs because of their facultative CAM metamorphosis, stress- tolerance and ability to re-sprout ( Butler and Orians, 2011 ; Farrellet al. ,2013 ; Nagase and Dunnett, 2012 ; Van Mechelenet al. ,2014 ) . Since none of the deep-rootedPhedimuspersons died in the survey, it must besides be noted that the high continuity of the species is another positive fac et.5.3 Plant Cover and Temperature of Studied Plant SpeciesIn current survey that have been examined in respects to the dealingss between the works screen and average temperatures of the mesocosms, there was the premise that the works screen would had influenced the temperatures. It was concluded that temperatures were so slightly influenced by the works screen, the higher the works cover the lower were the temperatures. This had so led to the decision that the species which are characterized by distributing via vegetive growing such asPhedimus floriferumandLotus corniculatusare advantageous for green roofs. A high screen and leaf wonts of workss can besides be good.5.4 Restrictions of the StudyAs antecedently stated the chief problem/limitation during measurings was the clip consequence on tray temperatures. In order to cut down the job of different heating throughout the twenty-four hours, measurings were carried out at midday when the radiation and the temperatures usually reach a tableland. Besides, dry and wet â€Å" unreal foliages † were used and exposed to the same environmental conditions ( air temperature, radiation, wind velocity ) as the trays in order to avoid theoretical appraisals of baselines. It was observed that the temporal temperature gradient decreased when the measurings were carried out at midday. By this, the clip consequence was partially solved but it still existed. Furthermore, for most of the measuring day of the months at that place was a good convergence between the temperatures of unreal foliages measured by the usage of thermocouples and the IR-camera. Thus the emissivity needed non to be adapted. As mentioned antecedently, the thermic imagination was performed within two hours and this period of clip could hold resulted in big differences in ambient temperature or the consecutive warming of the trays. One solution was to cut down this clip period but due to the high figure of trays it was about impossible to execute the thermic imagination in a shorter clip length. Maes and Steppe ( 2012 ) had besides indicated this restriction in thermic imaging so they alternatively highlighted the clip devouring process of thermic imagination. Another solution to execute thermic imagination of all trays in one spell is the usage of aircraft but this method leads to a instead harsh declaration of images ( Leuzingeret al. ,2010 ) . It is besides of import to observe that the clip consequence had complicated the finding of the important differences between the systems, due to the high criterion divergences. However, the consequences of this survey clearly indicated important differences between the systems and the control trays. Besides, it can be concluded that systems equipped with species such asKoeleria glaucaandLotus corniculatusshowed satisfactory consequences and could be characterized as being appropriate works species. The restriction as stated above in respects to the clip consequence besides led to the determination to maintain the emissivity to a default value of 1 since the survey was concerned in temperature differences between the systems and non in the absolute temperatures of the objects ( works leaves, dirt substrate, pebbles and lava ) . However, as mentioned in subdivision 3.3.1 during March and April 2014 ( before the measurings started ) several efforts were made in order to define/calculate the emissivity of the studied works species but because of the complexness the efforts were kept to a lower limit. It is deserving observing that most surveies on works temperatures set emissivity to a default value and that there are merely little differences between dirt and works emissivities ( Leuzinger and Korner, 2007 ; Maes and Steppe, 2012 ) . It would besides be interesting to analyze day-to-day rhythms of leaf temperatures particularly inPhedimussince it is a facultative CAM species. Unfortunately another restriction of this survey which wasn’t conducted was that this survey didn’t examine the day-to-day behavior in footings of the temperature and transpiration of the workss. If the restriction had been conducted the behavior ofPhedimuswould hold besides been researched in order to detect its transpiration.5.5 Inventions of the StudyDespite the restrictions mentioned above that had non been conducted the current survey is the first in which a high figure of replicated green roof mesocosms were researched. Every system had eight replicates and the control trays were seven. This high figure of replicates is sufficient for stand foring temperature measurings, which had ne'er been studied on green roof works species. The measurings were carried out from May until July in 2014. This long measuring period allowed more observations about the studied works species and their thermic behavior over clip in different conditions conditions and state of affairss. The usage of IR-thermometry can be considered as another invention since this method is new and it started to be used in recent old ages. However, this could be seen as a hazard since there are no fixed protocols available for IR-thermometry on workss. As antecedently mentioned, the usage of thermic imagination and infrared cameras enables the observation of thermic conditions of the objects in item. The technique of infrared thermometry has started to be normally used because of its truth. Infrared cameras are now being used more and more by works scientists because the costs of the equipment has been diminishing. Another of import factor is the usage of image analysis to derive mean, lower limit and maximal temperatures of selected objects and it has besides brought in a new method in respects to research. The corresponding package of the camera, IRBIS ®, has been a really helpful tool in order to research the temperatures of the studied workss. As a farther affair in respects to the statistical analysis that was performed in order to place important differences between the mesocosm systems, and controls and besides between the different types described as advanced because so many statistical trials were carried out for each day of the month of measurings in order to compare the systems.6 DecisionIn the last decennaries, the effects of planetary heating have become progressively seeable. One technique used to extenuate urban heat is the building of â€Å" green roofs † , a method that is progressively used in many states. Green roof workss have the capableness to change the microclimate outside and inside of edifices. A new method to look into the temperature and accordingly the chilling potency of workss is infrared thermometry. Thermal imaging utilizing infrared cameras enables the observation of thermic conditions of the objects in item. Topographic point measurings of foliage temperatures utilizing thermocouples a re inferior to IR-thermometry but the latter attack has restrictions, excessively. The survey was carried out to look into the effectivity of five commonly used green roof works species:Koeleria glauca( a grass ) ,Lotus corniculatus( a leguminous plant ), Dianthus carthusianorum( a herb ) ,Thymus serpyllum (a low turning bush ) andPhedimus floriferum( a succulent ) . The undermentioned three hypotheses were tested: – The workss have an effectual chilling potency as compared to the bare dirt. – TheSedumspecies,Phedimus floriferum,could hold a positive consequence on the other species and could cut down heat emphasis. – Plant mixtures of different species are more effectual than monocultures. The overall aims of this survey was to i ) Compare the deep-rooted trays with control trays ( au naturel dirt ) in order to look into the chilling potency of workss. two ) Examine the effectivity ofPhedimus floriferumin footings of evapotranspiration, heat consequence extenuation and possible positive consequence on the other species. three ) Compare the works mixtures with monocultures to place important differences. The consequences in general supported the first hypothesis. It had particularly supported the speciesKoeleria glaucaandLotus corniculatusand some of the mixtures with these species holding shown to hold significantly lower surface temperatures than the controls trays and some of the deep-rooted mesocosms for the whole measuring period. The consequences in respects to the 2nd hypothesis was besides supported.ThePhedimus floriferumso had a positive consequence on the other species as the combinations with the species kept the temperatures at lower degrees during the measurement period. SincePhedimusis a extremely drought stress-tolerant and relentless species, it had a positive consequence on the ecological services of green roofs. The consequences besides lead to the credence of the 3rd hypothesis that works mixtures are more effectual than monocultures since the best systems in footings of extenuating the heat effects were works mixtures. However, the survey besides faced some restrictions such as the clip consequence on tray temperatures and the proper accommodation of emissivity values. Several efforts were made and several methods were applied in order to turn to those limitations. Harmonizing to the literature, old surveies had faced the same restrictions. In order to cut down the clip effects during measurement runs of a high figure of replicates, high scaffolds should be used from which all objects can be monitored in one spell. However, due to the big field of position the low declaration of images would hold been a job. Taking exposure of all the objects at the same clip had its advantages in that many images could be taken over clip, e.g. to analyze day-to-day temperature rhythms of works surfaces. This could be characterized as an mentality which should be investigated farther by similar experiments in the hereafter, in order to see whether it helps the survey to minimise or extinguish similar restrictions and limitations and besides to lend to this current research.

Colored Smoke Recipes - Easy Formulations

Colored Smoke Recipes - Easy Formulations One way to make smoke is to craft a smoke bomb, but you can make a smoke powder, too. Here are some formulations for colored smokes. The parts or percents are by weight. Basically what you do is measure the ingredients, sift them together to mix them, and ignite the powder to produce smoke. Up to 2% sodium bicarbonate (baking soda) may be added to slow the combustion/cool the reaction, if necessary. White Smoke Recipe Potassium nitrate - 4 partsCharcoal - 5 partsSulfur - 10 partsWood dust - 3 parts Red Smoke Recipe Potassium chlorate - 15%para-nitroaniline red - 65%Lactose - 20% Green Smoke Recipe Synthetic indigo - 26%Auramine (yellow) - 15%Potassium chlorate - 35%Lactose - 26% Reference: The formulations for colored smoke bombs came from Wouters Practical Pyrotechnics, who cited the recipes as originating from L.P. Edel, Mengen en Roeren, 2nd edition (1936). Wouters website is very helpful. Though I didnt see recipes for other colors of smoke, he has an extensive list of formulas for colored fireworks, which you may be able to adapt to make colored smoke. More Dyes and Colors If you can order chemicals, here are some of the dyes used to produce more colors: Red: Disperse Red 9 (older formulation)Solvent Red 1 with Disperse Red 11Solvent Red 27 (C.I. 26125)Solvent Red 24 Orange: Solvent Yellow 14 (C.I. 12055) Yellow: Vat Yellow 4 with benzanthrone (older formulation)Solvent Yellow 33Solvent Yellow 16 (C.I. 12700)Solvent Yellow 56Oil Yellow R Green: Vat Yellow 4 with benzanthrone and Solvent Green 3 (older formulation)Solvent Yellow 33 and Solvent Green 3Solvent Green 3Oil Green BG Blue: Solvent Blue 35 (C.I. 26125)Solvent Blue 36Solvent Blue 5 Violet: Disperse Red 9 with 1,4-diamino-2,3-dihydroanthraquinoneSolvent Violet 13 Use care if you try these additional dyes.

Free Essays on The Comparative Analysis Of The Computer History In The USSR &USA

Introduction Once in a lifetime a new invention will come about to touch every aspect of our lives. Such a device that changes the way we work, live, and play is a special one, indeed. A machine that has done all this and more now exists in nearly every business and one out of every two households. This incredible invention is the computer. The electronic computer has been around for over a half-century, but its ancestors have been around for 2000 years. However, only in the last 40 years it has changed the society. From the first wooden abacus to the latest high-speed microprocessor, the computer has changed nearly every aspect of people’s lives for the better. The very earliest existence of the modern day computer’s ancestor is the abacus. These date back to almost 2000 years ago. It is simply a wooden rack holding parallel wires on which beads are strung. When these beads are moved along the wire according to â€Å"programming† rules that the user must memorize, all ordinary arithmetic operations can be performed. The next innovation in computers took place in 1694 when Blaise Pascal invented the first digital calculating machine. It could only add numbers and they had to be entered by turning dials. It was designed to help Pascal’s father who was a tax collector. In the early 1800’s, a mathematics professor named Charles Babbage designed an automatic calculation machine. It was steam powered and could store up to 1000 50-digit numbers. Built in to his machine were operations that included everything a modern general-purpose computer would need. It was programmed by and stored data on cards with holes punched i n them, appropriately called punchcards. His inventions were failures for the most part because of the lack of precision machining techniques used at the time and the lack of demand for such a device. After Babbage, people began to lose interest in computers. However, between 1850 and 1900 there were great advances...

Discussion Post Movie Review Example | Topics and Well Written Essays - 500 words

Discussion Post - Movie Review Example It is important to note and mention that he involves humor thus introducing comic relief ensuring the audience relaxes to engage during the presentation. Another advantage and merit is that David Gallo uses hands and gestures to make points clearer and show vigor during the presentation (Dunlap & Lowenthal, 2011). This is to mention that the use of body language enhances the ease of putting the message across thereby stressing on the important issues and points. In some instances, the speaker uses short sentences which in conventional knowledge are used to portray tension. Thus, the fact that David Gallo uses short sentences at the end of the presentation is akin to introducing tension or some sort of edginess in the presentation. In all fairness and respect, the use of short sentences is a short coming of the presentation. Similarly, there is less use of rhetoric questions in the presentation which means that the presentation translates to a monologue. Thus, few uses of rhetoric que stions reduces the presentation to a one man show. From the outset, it is notable that he uses a fast paced approach of talking in his speech. This is so because one easily notes that he speaks in a relative fast pace. It is important to note and mention that the voice of Sir Ken Robinson is commanding and authoritative in a way and manner. In terms of his use of stage, he does not move around the stage and instead stands in one place. This is to say that he does not engage the whole audience effectively. Secondly, he maintains eye contact with the audience thus improving the appeal of the audience and attract their attention. Equally interesting in the presentation of the speaker is that he maintains facial expression which are used to mean and imply different things. For instance, during the times of humor, he contorts his face in a friendly way therefore engaging the audience during the light moments. On the other hand, this presentation is non-interactive because the speaker

How different was Sparta from other Greek States Essay

How different was Sparta from other Greek States - Essay Example Some scholars feel that other states felt that Sparta was too obsessed with war and power and that this is the reason why this stated paid attention to the development of a strong army and their involvement in war. Additionally, this is the city that gave a woman the right to conduct business and train for war. Resultantly, other states felt safe to associate with Sparta especially during periods of war. A deep analysis of the Sparta state will unveil the difference of this state compared with other states. The Sparta social structure comprised of three categories of individuals; the citizens, Periokioi and the Helots. The citizens formed the large group of native citizens who were the original habitants of the land. This group of people formed the loyal part of the society. They formed part of the army and had the absolute right to own any kind of property. In the structure oligarchy that existed, the citizens were the superior people that dominated the society. The Periokioi were a group of people who had migrated to this society. They formed the intermediate group that separated the inhabitants and slave. Since this group was way below the habitants, they were not allowed to partake in military action but could own land and control business. They trusted than the minority group of the Helots in this society. The Helots were those people who had entered the country and did not have the right to own land nor participate in war. The formed the source of labour and worked in the lands a nd business enterprises in the society. As observed, the country applied oligarchy unlike other nations such as Athens that were fully democratic1. On this note, this was a good environment only for the original habitants while the aboriginals were treated as inferior beings. The military system in Sparta was stronger than any other in the whole of Greece. The Original citizens in this state were compulsorily supposed to attend military training at their early age. Unlike in
