Solvothermal Preparation of CaTiO3 Prism and CaTi2O4(OH)2 Solvothermal preparation of CaTiO3 prism and CaTi2O4(OH)2 nanosheet by a facile surfactantfree method Weixia Dong, Gaoling Zhao, Bao Qifu, Gu Xingyong, Gaorong Han Abstract: Calcium titanate (CaTiO3) with prism-like-shaped morphology were synthesized by a simple solvorthermal process without any surfactants. It is found that NaOH concentration plays an important role in the formation of CaTiO3 prisms. A rational mechanism is proposed to illustrate the growth of CaTiO3 prisms. And the CaTi2O4(OH)2 interlaminar structure is illustrated. Keywords: solvorthermal preparation, surfactant-free, CaTiO3 prism, CaTi2O4(OH)2 interlaminar structure Introduction Due to its widespread potential applications in a lot fields, calcium titanium oxides have been considered as one of the most important inorganic materials. The most classic model for shape control is the Wulff facets argument or Gibbs-Curie-Wulff theorem, which suggests that the shape of a crystal depends on the relative specific surface energy of each face or facet of the crystal 1. However, our experiment results show that this pure thermodynamic can not explain well. It can be the concentration of existing monomers by tuning NaOH concentration plays a key role for the evolution of the shapes and phases of the calcium titanium oxide crystals 2. If the pH values can be well-controlled, the growth of crystals with different morphologies should be possible. As a result, the concentration of the remaining monomers after the nucleation process is dependent on the number of nuclei formed. To maintain the correct pH of the solvorthermal system, it is necessary to use alkaline or acidity mineralizers (i.e. pH adjusting agents). NaOH or HNO3 are most convenient for this purpose. However, intermediates are often observed during the preparation of CaTiO3. The presence of this impurity phase significantly affects the material’s properties and, thus, it should be avoided. Therefore, it is worthwhile to compare NaOH concentration that are necessary to obtain phase-pure caltium oxides 3. In the present work, calcium tantium oxides was prepared by a solvorthermal method by tuning NaOH concentration. A rational mechanism is proposed to illustrate the growth of CaTiO3 prisms. And the CaTi2O4(OH)2 interlaminar structure is analysised by XRD, SEM and FT-IR . Experimental procedure Synthesis The CaTiO3 crystals were synthesized in an aqueous medium by a solvothermal route. In a typical synthesis, 0.01mol Ti(OC4H9)4 (Sigma Aldrich, 99%) were mixed with molar ratio of water/enthonal=10/10. In particular, pH value of deionized water was adjusted 1 by adding HNO3. Then added to 10 ml of a 1 M CaCl2 ·5H2O solution under vigorous stirring at room temperature. After the solution was stirred for 5 min, various NaOH concentration (0.005 M, 0.01 M, 1 M, 3 M, 5 M, 7 M) was added to adjust the pH. Subsequently, the autoclave was sealed and maintained at180  °C for 36 h, followed by natural cooling to room temperature. Afterward, the final products were centrifuged, washed with deionized water and absolute ethanol several times, and then dried at 80  °C for 15 h in air. Characterization The morphologies of the powders were investigated by field emission scanning electron microscopy (FESEM, Hitachi S-4800, Japan). The crystal phases of the products were characterized by X-ray diffraction (XRD, PANalytical X’Pert Pro, Holland), in a 2ÃŽ ¸ range from 100 to 800, using Cu-Ka radiation. UV–Vis absorption was measured by a TU-1901 spectrophotometer equipped with a reflectance attachment and BaSO4 was used as the reference material. Infrared spectra of the samples were obtained using a Nicolet Nexus 470 Fourier transform infrared (FT-IR) spectrometer in the 400-4000 cm1 region by KBr pellet. Results and discussion We have systematically investigated the system in various NaOH concentrations while keeping the other reaction conditions unchanged, as shown in Fig. 1 and Fig. 2. Fig. 1 XRD patterns of samples synthesized at different NaOH concentrations: (a) 0.005 M, (b) 0.01 M, (c) 1 M, (d) 3 M, (e) 5 M, (f) 7 M. Fig. 1 shows the XRD patterns of the samples synthesized in various NaOH concentrations. When NaOH concentrations is 0.005 M, the sample is CaTi2O5 (JCPDS card 25-1450) phase. When NaOH concentrations is 0.01 M, the sample is pure CaTi2O4(OH)2 (JCPDS card 39-0357) phase (Fig. 1(b)). When NaOH concentrations increases to 1 M, intensity of CaTi2O4(OH)2 phase increases. Further increasing NaOH concentration to 3 M, CaTi2O4(OH)2 phase disappears and CaTiO3 (JCPDS card 42-0423) appears with a little trace of Ti3O5 and Ti4O7. When NaOH concentrations is above 5 M, pure CaTiO3 is obtained and peak intenisity of CaTiO3 further increases, which indicates well crystallized. Fig. 2 FESEM images of the samples synthesized at different NaOH concentrations: (a) 0.005M, (b) 0.01M, (c) 1M, (d) 3M, (e) 5 M, (f) 7 M. When NaOH concentrations is 0.005 M, CaTi2O5 aggregated particles are obtained (Fig. 2(a)). When NaOH concentrations is 0.01 M, CaTi2O4(OH)2 porous needlelike and floating irregular clouds-like particles are obtained (Fig. 2(b)). When the NaOH concentrations are 1 M, CaTi2O4(OH)2 morpholgy is mainly composed of overlap leaves (Fig. 2(c)). When the NaOH concentrations are 3 M, nanosheets disspeared, and a lot of aggregated particles with a little trace of prisms(Fig. 2(d)). Whereas above 5 M, CaTiO3 rectangular prisms were formed (Fig. 2 (e)-(f)). On the basis of all the above observations, it is indicated that the presence of NaOH concentrtion in the solution is necessary for the formation of calcium titanium oxides. From the viewpoint of the chemical composition effect, the NaOH concentration may influence the combination of free Ca2+ and release Ti4+ ions of TiO2 in the solvothermal process [4]. Due to forming a lower amounts of active OH ions and small amounts of TiO2 soluble species in low NaOH concentration (0.005M, 0.01M), reactive Ca2+ and TiO2 causes the reaction to be controlled by the transport of TiO2 soluble species from hydroxide crystals to an interface bearing reactive Ca species. A shortage of TiO2 soluble species near Ca2+ will halt the reaction to form CaTiO3. Instead, owing to the small solubility of titanium dioxide in the acid conditions, CaTi2O5 forms. Increasing NaOH to 0.01M, the solvothermal processing accelerate the TiO2 formation and promote TiO2 to transform small amounts of Ti4+ ions [4-5], which are involved in a reaction with Ca2+à ¯Ã‚ ¼Ã…’leading to the formation of CaTi2O4(OH)2 crystallites. However, a large amount of Ti(OH)4 was formed when NaOH concentration was increased to 1M, O-H group of TiO6 octahedron free end decreases, the probability of Ca2+ into the lattice of the increase, the formation of tetragonal CaTiO3 particles. With the increase of NaOH concentration to 5 M, i. e. in the high OH ion concentration, because of solvothermal synthesis of CaTiO3 crystal defects and grain size effect, CaTiO3 particles are formed. For the cubic phase CaTiO3, (110) and (100) surfaces can exist at the same time, gamma (110) is slightly larger than the gamma (100) crystal[3-4], which makes the tetragonal CaTiO3 nanocrystals along (110) plane and (100) surface growth, so CaTiO3 particles will give priority to the relatively low surface energy (100) surface growth, resulting in the formation of prism. Further increasing NaOH concentration, prism further Ostwald ripening, formi ng distinct edges and corners of CaTiO3 prisms [3-4]. A detailed time study is obvious for the growth process of the CaTiO3 prism in the case of 7 M NaOH. Unfortunately the experiments show the CaTiO3 prism are quickly fromed due to the fast growth rate, which prevents the direct observations of its detailed growth process. Howerver, based on the morphology evolution (Fig. 2(a)-(f)) , the growth process of CaTiO3 prism by the solvothermal process with 7 M NaOH is simply illustrated in Fig. 3. Fig. 3 Schematic representation of the growing process of CaTiO3 prism-like structures. In previous researches, our work found that CaTi2O4(OH)2 may have photocatalytic and electrochemical properties [5-6]. On view of the potential application, the structure of CaTi2O4(OH)2 is what we want. Fig. 4 shows FT-IR spectra in the range of 400-4000 cm–1 of CaTi2O4(OH)2 sample. The peaks at 3425 cm1 can be attributed to the O-H stretching. Compared with free –OH ( 3600 cm-1 )à ¯Ã‚ ¼Ã…’the absorption peak shifts to low wavelength, which is due to the coordinated water molecules via hydrogen bonding interaction to the CO32- of the interlamination [5]. The broad absorption band observed at 3200 cm-1 is originated from the presence of hydroxyl groups of water 7. The absorption peak at 1538 cm-1 attributes to H-O-H bending of the lattice water 8. The sharp absorption peak at 1357 cm-1 attributes to C-O-C bending of carbonate ion. A band centered at 750 cm-1, which is attributed to isolated tetrahedron TiO4 stretching vibration. The absorption bands below 500 cm-1, i . e. bands centered at 495 and 425 cm-1 can be ascribed to Ca-Ti-O bending vibrations 8. From XRD and FT-IR results, the interlamination contains CO32-, H2O, isolated tetrahedron TiO4 and –OH ions, Fig. 5 shows diagrammatic sketch of CaTi2O4(OH) 2 sample. Fig. 4 FT-IR spectra in the range of 400-4000 cm–1 of CaTi2O4(OH)2 sample. Fig. 5 Diagrammatic sketch of CaTi2O4(OH)2 sample. Conclusion In summary, we report here a simple solvothermal process for the formation of pure calcium tantium oxides without any surfactants. It is also found that the appropriate concentration of NaOH is vital for the formation of CaTiO3 prism. A possible mechanism has been proposed to explain the formation of CaTiO3 prism. And the CaTi2O4(OH) 2 interlaminar structure is illustrated. Acknowledgement The present work was supported by the National Natural Science Foundation (Grant No. 51262014 and 51172201). References H.

Imagery and Diction in The Fish by Elizabeth Bishop Essay -- The Fish

Imagery and Diction in The Fish by Elizabeth Bishop Elizabeth Bishop's use of imagery and diction in "The Fish" is meant to support the themes of observation and the deceptive nature of surface appearance. Throughout the course of the poem these themes lead the narrator to the important realization that aging (as represented by the fish) is not a negative process, and allows for a reverie for all life. Imagery and diction are the cornerstone methods implemented by Bishop in the symbolic nature of this poem. The title of the poem itself dictates the simplicity Bishop wishes to convey regarding the narrator's view of his catch. A fish is a creature that has preceded the creation of man on this planet. Therefore, Bishop supplies the reader with a subject that is essentially constant and eternal, like life itself. In further examination of this idea the narrator is, in relation to the fish, very young, which helps introduce the theme of deceptive appearances in conjunction with age by building off the notion that youth is ignorant and quick to judge. Bishop's initial description of the fish is meant to further develop this theme by presenting the reader with a fish that is "battered," "venerable," and "homely." Bishop compares the fish to "ancient wallpaper." Even without the word ancient preceding it, the general conception of wallpaper is something that fades into the background. One is not supposed to take much notice of it. To add to this impartial picture, the fish is brown, the signature color of dullness. "Shapes like full-blown roses stained and lost through age" (lines 14-15) further cement the image of something with little time left. Fully bloomed roses conjure the image of a flower whose petals are at t... ...tor's growing relationship with the fish. She creates, first, an image of the fish as a helpless captive and the reader is allowed to feel sorry for the fish and even pity his situation as the narrator does. The narrator's relationship with the fish then grows to one of personal regard as he engages in further study and is able to look past his initial observation. The parting image of the rainbow offers a perfect way to drive home the process of aging as a dignified and even celebratory act. Not only is it a very optimistic image of color and gaiety, but the rainbow is traditionally paired with the concept of treasure once the end of it is reached. When applied to the intended message of the poem, it may be interpreted that Bishop is implying that nearing the end of one's life is like nearing the end of the rainbow and accepting a reward for a life well lived.

Hunting should not be outlawed Essay

Hunting should not be outlawed. It is still a source of food for people who still live off the land . Hunting can be a very effective method of population control. Hunting is a sport of tradition it offers recreation from everyday life. Hunting animals for food is better for people because it does not have all the hormones that farm raised animals have. There aren’t very many diseases that affect humans in wild animals. Majority of the animals that have seasons are edible. Hunting is a very effective method of population control. If too many animals of one species or several related species live in one area they could possible wipe out there entire food source or sources. Then many of them would starve to death which unknown to the tree huggers that want to stop this is a very painful death, being shot is a very quick painless death. Hunting can save an ecosystem and entire species, by killing some of the animals in the ecosystem you can save the food source for the animals still left living. Hunting is a tradition in most of the world. People have been hunting for tens of thousands of years. Many people still use hunting as their many food source throughout the world. It is also a recreational activity. Tradition’s should not be outlawed. Hunting can help save the environment in which they live in by population control. It is a source of food. It’s an activity that people have been using to get away from society as we know it for several years. In conclusion Hunting should not be outlawed.

Business Proposal Sample

Business Proposal Sample In today’s modern world, people seem to be always on the move engaging themselves in different activities. It is interesting how people are capable of doing the many activities in an easy and coordinated way, thanks to the modern navigation tools like cars. The fact that humans seem to move most of their time covering a considerable number of miles in just a few hours, a situation that was impossible some centuries back, safety during this movement is essential. This is because movement from one place to another makes a considerable part of today’s people. 1. The Mission and Vision Maka GPS Technologies Pte Ltd saw the need for the removal of driving barriers by introducing a range of quality navigation products to cushion modern transport, logistics and output efficiency. The company’s dedication to quality, high innovation and reputable products in the market serves as the basis for the organization of the company becoming competitive standing out as the preferred brand, Morbella. The high demand for the products and experience the companys employees got from Singapore are the driving forces behind the need to expand the market coverage to other places like Indonesia, Malaysia and Australia among many others. 2. Core values Maka GPS Technologies is a telecommunication and e-commerce solution provider with its establishment first launched in Taiwan in the year 1998. However, it extended its wings to Singapore in 2006 and later to Johor Bahru, and Kuala Lumpur by establishing distribution offices in the areas in an effort to extend the services to customers worldwide. The company has thus developed into a leading navigation company that provides a considerable range of services. Some of the services are wholesale distribution of personal navigation devices and Bluetooth GPS receivers, GPS solution consultancy and integration services and corporate fleet management tracking. This shows that the company targets those people with navigation problems and those with safety issues as they go about the first paced world. The identified markets include Malaysia, Indonesia and China just to mention a few, and the company seeks to its brand as it works out solutions for their daily activities. The company has an ex cellent human resource, and quality control teams that will ensure the expansion is effective. The company seeks to orient the staff on the mission statement on the first day of their work. This orientation will ensure that they exercise the mission from the first day and on their daily bases so that they grow and live the mission statement. With products like Marbella, Qstar, Holux and HaiCom, Maka GPS Technologies hopes to deliver an enriching navigation experience across the group, which consists of five subsidiaries. This is through integration where the subsidiaries will work together to build a leading brand of the channel products in the market. At the same time, the company seeks to support the populace through the provision of leadership, embrace, and accumulation of knowledge for training and research. This is in addition to making deliveries, ensuring a competitive advantage and work closely with the community. This will ensure that the company creates a brand that speaks volumes about not only the product, but also the company. This follows the revelation that a journey has many elements, and for Marbella, the company wishes to produce a brand that amplifies the staff’s ability to deal with all the troubles concerning navigation. The company wishes to capitalize on the variety of brands it has to offer customers quality full package services, and this is to ensure that they have no other option but Marbella Car Navigator and Marbella roadcorder, which have many uses in one. This will be an added advantage for the business, and this is because it will be capable of fighting off competition from companies who can only manage a tapered array of the goods and services. Moreover, the organization of the business and the maximization of product support and timely adoption of product differentiation strategies set the business at par well ahead of its competitors. 3. Maka GPS Technologies Challenges The corporation has a team of skilled employees who have made it their priority to innovate, and produce quality products that can fit today’s world. However, the company is not well there, and this is where it wishes to be, to reach a point where the brand speaks for not only the product but also the company and employees of the company in good light. It is clear that, for any brand to be successful in the market, there has to be a concept behind the brand, its development and management and how it performs according to the target set (Singapore prestige brand award 16). It seems that the change of the logo to Morbella has attracted a lot to be desired from the public, but the company is still at low to live it. As the only GPS that’brings you around the world’, the company seeks to substantiate the claims and make more cost effective than other brands, which are foreign and not customer based. Given the significance of a brand to any given company, a lot has to be done on the brand that will ensure that they tip the scales in the consumer decision (Singapore prestige brand award 6). Maka GPS Technologies has the potential to ensure a quality product differentiation by a factor of hundreds of percentages, and this is only if they can determine what has made the once productive employees sail to the deep end. 4. Profiles solutions To achieve the targets of branding, the company has decided on a couple of things that could ensure the success. First of all, there should be an orientation of workers on the first day on the mission statement. This will ensure that everybody in the company works towards the solution. This is in addition to building a strong, relationship with the press and the marketing system so that there is the maximization of above the line and below the line marketing collaterals. All these efforts will be to ensure that the company achieves its marketing objective within the assigned budget. The company has also started investing in public relations, and this is where it offers to sponsor a considerable number of car related events with social media utilized as the interactive platform. The company is up to task to ease the acquisition of Morbella, and this is where there is provision of lifetime map updater support where a person can exchange within the warranty period at no extra cost. 5. Benefits of the solution With the solutions in place, there will be an exceptional return on investment and improved productivity. This is because it will reduce rising costs and labor crunch that seems to be a challenging hurdle to tackle. A premium brand name for any company’s products will always attract good workers and talent which then translate into a competitive advantage for the company (Singapore prestige brand award 7). This is because any successful brand name projects an image of quality and value, and this will keep customers coming back for any other of the company’s products thus bringing profit to the company. It is notable that the establishment of such a brand requires passion, creativity, courage and conviction, therefore, a massive overhaul of the entire employee team are preferable. This is in addition to keeping the competent, ones as well as adopting new talented employees. This will require competent brand building, which may involve extra marketing activities ghat will be localized, and at the same time be collateral to ensure the marketing and promotion delivers a maximum branding value to the local consumers. This includes the magnitude of his contribution to the company, and what can be done to determine the targets for the entire team. At the moment, things are looking up for the company, and this is because the company has delivered some of the promises it made and still sees growth in the local market share combined with a convincing sales result. The company hopes that the customer will continue having the sense of value to their brand and with the image of quality the brand projects, the company is headed for great success.

The relationship between inflation and unemployment in Vietnam Essays

The relationship between inflation and unemployment in Vietnam Essays The relationship between inflation and unemployment in Vietnam Paper The relationship between inflation and unemployment in Vietnam Paper Part I Vietnam s economic growing depend on two chief factors: internal ( the stimulation of economic system export and import ) and external factors ( planetary environment market and Vietnam s fight ) . In general tendency, Vietnam s GDP has gone up from 7,8 % in 2004 to 8.5 % in 2007. But, it merely reached merely 6.2 % ( 2008 ) and 5.3 % in 2009 because of fiscal crisis.[ 2 ] In 2009, Vietnam economic system has a positive alteration: GDP increased over the quarters for all twelvemonth, this increasing is about 5.32 % . In this twelvemonth, the GDP growing despites a lower growing rate of 6.2 % in 2008 but has exceeded 5 % mark set[ 3 ]. Vietnam s economic system is divided into three big sector economic system: agribusiness, forestry and piscaries. In 2008 Vietnam exported about 64.8 billion U.S dollars, of which about 32.1 % of export value was the heavy industry and minerals ; 45.2 % was light industry and handcraft ; 32.5 % were agricultural, forestry and piscaries. During that same twelvemonth, the import value reached 60.8 billion dollars, of which the estimated 30.2 % of imports were machinery, equipment, tools of all sorts and 63.7 % were natural stuffs informations, merely 6.1 % for consumer goods. Vietnam s mean income existent GDP per capita has grown quickly since the state launched the Doi Moi Reform, turning at an mean one-year rate of 5.06 per centum between 1986 and 1997 ( pre-Asian Financial crisis ) and at the higher rate of 5.64 per centum between 1997 and 2009 ( Figure 2.1 ) . Vietnam stood out as one of the fastest turning economic systems in the universe during this period leting it to make the lower middle-income group in 2008 when its per capita income exceeded USD 1,000. And it continues to do important advancement since, despite the recent fiscal crisis [ 4 ] The foreign investor considered that Viet Nam is a 2nd absorbing finish next to China in the Asia- Pacific country. FDI capital have an of import portion in National budget and to assist besides Vietnam economic system higher growing in the last few old ages.[ 5 ] In 2010, the economic growing has estimated at 6.5 % . The growing is the fastest in Southeast Asia but it still inferior China, South Korea, Taiwan and Thailand when they were at similar phases of development. But the monetary value could transcend 12 % in the approaching period, bespeaking the hazard of raising rising prices.[ 6 ] In the close hereafter, Vietnam s economic growing advancement will concentrate mostly ability to pull foreign investing and do a alteration in Vietnam s economic competitory ability. Vietnam will hold to travel tete-a-tete with China in pulling increased sums of foreign direct investing. Part II Inflation Inflation is one of the major challenges to Vietnam s economic system. It is besides the ground for slow growing of the province of the economic system of Vietnam. Inflation is understood as the uncontrolled addition in monetary value. It mean the devaluation of Vietnam currency. Because of the fluctuation of the US economic system, the exchange rate between Vietnam dong against US changed a batch within general increasing tendency which is showed in the figure beside[ 7 ]. As a consequence of that, most of company applied USD in their dealing alternatively of Vietnam dong, particularly in export goods. Beside that, several of Vietnamese individual who want to salvage their money in USD. Both of the grounds make the exchange rate kept traveling up and up. The escalation of monetary value make the consumer monetary value index in Vietnam has besides increase as show in figure following to with lift 1,05 % in October, 2010 by higher monetary values of instruction and nutrient sectors.[ 8 ] It is besides make the cost of goods or merchandises grow up. Viet Nam is one of the most state import really much ( 90 % GDP ) , the higher monetary value of fuel, stuff cause the higher monetary value of goods or merchandises. The company will bring forth less and the monetary value of goods maintain increasing. The rising prices in Viet Nam does non halt fluctuation. It comparative low in the mid-2000s and keeps traveling faster in recent old ages. The rising prices over the bound ( 9 % ) . In 2007, the rising prices is the double-digit rising prices. Between 2008s and 2009s was peculiarly terrible with the highest per centum of inflation- about 25 % . The rising prices is traveling down in 2010 ( 7 % ) because of the authorities policy.[ 9 ] On the other manus, the payment on the authorities is one of the biggest grounds, which cause the rising prices. If the authorities wage more money for goods and services, the money they pay is travel straight into the economic system, which cause the higher demand. Examples: The monetary value of rice export in 2007 go up 15 % from 2006 so the demand of rice export go up. At that clip, the supply can non run into the demand because of the catastrophe or another factors. All factors cause the demand -pull rising prices which makes monetary value of goods, merchandises or services grow up.[ 10 ] Viet Nam is a little economic system in the Asia, but Viet Nam makes an impressive by velocity of economic grow. So that is the ground why Viet Nam must pay for their fast and large success. To forestall the rising prices, the authorities should make many thing to forestall the turning of rising prices. They need to command the money they give to the economy-increase the value of money. On the other manus, the authorities must utilize their power to take down monetary value some necessary things such as nutrient or household usage in other to assist the hapless people and do the balance between demand and supply. Part III Unemployment The unemployment rate in Viet nam is a peculiar job. There are some grounds for this issue. It makes demand and supply of labour unequal, in fact, more supply than demand so that unemployed has rosin. What is unemployment? Unemployment is a statement that economic experts use to stand for all of people who in working age and ca nt happen a occupation or the workers who lost their occupation, but they are valuable for work at current pay rates. Unemployment rate is the figure unemployed expressed as a per centum of the labour force. [ 11 ] The statistics below which shows the unemployment rates in the different urban countries in Viet Nam signifier 1996 to 2008[ 12 ]: The highest rate was about 7 % of Vietnams population in 1998, and the general tendency went up from 1996 1998 and so went down 1999- 2008, except 2009. Most of unemployees are in the large metropolis and major economic country like Ha Noi, Ho Chi Minh metropolis, Da Nang or Dong Nai states. % First, Vietnams population growing has reached 86 million people ( 2009 )[ 13 ], the 6th in Southeast Asia, and besides extremely increase in one-year.

Murder of Nixzmary Brown - Article Example r old girl who was abused emotionally, sexually, and physically by her step-father over an extended period of time before being murdered at her parent’s home in New York. The suffering endured by the helpless little girl did not appear to go unnoticed. However, the problem was that the adults who noticed welts on her body, or other odd marks, were reluctant to approach the authorities about what they were witnessing. Years before Nixzmary’s step-father finally put an end to her life by viciously hitting her on the head, there were signs that appeared to indicate that Nixzmary was not developing as a healthy normal little girl. According to (Dan, 2006) it was only after Nixzmary’s tragic death that a pattern began to emerge in the sequence of odd coincidences in her earlier life that showed that she was being exposed to extreme suffering. According to Dan (2006) school workers in Nixzmary’s school often reported that she would be absent for extended periods of time. In addition, it was not uncommon for her neighbors to notice unsightly welts among other unexplained injuries on her body. It would seem that Nixzmary was an uncommonly clumsy child because her mother would often state that she fell down, or banged her arm or head on a piece of furniture; thus causing these marks on her body. According to Siegel & Welsh (2009), the family’s neighbors even noticed that Nixzmary was underweight and scrawny for her age. Though child welfare workers were alerted about the case, they did not report any oddities, and left the family to itself. Staff members from Nixzmary’s school even tried to visit her at home when she began to be absent on a regular basis. However, they were stopped from entering the house where the little girl was being systematically tortured unless they could produce a warrant that permitted an investigation. In January, 2005, Nixzmary’s step-father, Cesar Rodriguez came home and found a cup of yoghurt missing (Cohn & Russell, 2012). Upon

Is global warming a genuine threat to the planet earth Essay

Is global warming a genuine threat to the planet earth - Essay Example Further the rise of global warming phenomenon also led to the rise of climatic heat and humidity spreading many diseases which claimed a large number of lives in regions like Chicago. The incidence of global warming also affected the geographical and topographical formations by causing rivers like Mississippi to completely dry up. (Stein, 2001, p.5). The incidence of global warming to a huge extent is rendering huge impact to the pattern of life forms on the earth and thus has become a considerable threat to the planet. Thesis The incidence of global warming is becoming a gradual menace by the annihilation of several species of flora and fauna from the earth’s surface. Effects rendered by global warming generally encompass larger areas of the planet whether filled or not filled with biological species. The intensity of the effect of global warming in annihilating larger forms of biological species is still contested for lack of proper research activities in this direction. Hig h concentrations of carbon dioxide, a potential contributor to the greenhouse effect, in the atmosphere is observed to be the major factors for large number of species to evaporate out of the earth’s surface. Estimates made show that around 43 percent of the total biomass possessed by the earth in major tropical regions go extinct on account of the effect of global warming. ... (Malcolm, Liu, Neilson, Hansen & Hannah, 2006, p.539, 544). The incidence of global warming cause rapid changes to the climatic parameters of different regions and thus can be taken as a significant contributor of the extinction of many biodiversity species from the earth’s surface. The cause of the extinction of different life forms on the planet earth has been hugely attributed to the changes in climatic patterns. Estimates made show that incidence of high amount of climatic changes contribute to around 35 percent to the extinction of different life forms. Large amount of human activities like deforestation and other industrial and commercial activities are the potential contributors behind intensifying the effect of global warming. (Thomas, Cameron, Green, Bakkenes, Beaumont, Collingham, Erasmus, Siqueira, Grainger, Hannah, Hughes, Huntley, Jarrsveld, Midgley, Miles, Huerta, Peterson, Philips & Williams, 2004, p.145). Thus it is found that the occurrence of global warming i s one of the major contributors behind the gradual extinction of many recorded and unrecorded life forms from the face of the planet. The deforestation of trees and other industrial effects are emitting large amounts of carbon dioxide gases in the atmosphere causing warming up of the climate. Rising climatic temperatures amount to the event of global warming causing the event of extinction of life forms. Anti-Thesis The above discussion hints that a large part of the flora and fauna of the planet has earned extinction owing to the harmful effects of global warming. However such a statement fails to gain much strength for a number of factors have been researched which are not related to the
