Malunggay Bark Extract As A Source Of Electricity

Malunggay Bark Extract As A Source Of Electricity The 21st century trend is an era in which technologies become part of human lives. In this age, efforts and time are exhausted by many individuals or groups in order to create technologies that can be utilized in any human endeavour. Conversely, for most of these innovations and inventions to function, electricity is required. In the Philippines, a country that is abreast with technologies, majority of the electricity requirement is derived from electric power plants that are run by fossil fuels such as petroleum and coal. Moreover, batteries which are portable source of the said energy are also in use. However, due to rapid increase in technologies that require electricity, some problems arise. At present, since there is a huge demand for electricity, fuel required to generate such energy becomes scarce. People have realized that most of processes and materials for electricity generation have negative effect on the environment and on health of human. Hence, researches are conducted to discover green (clean, natural, derive from biological source), low cost, and readily available alternative source of electricity. In line with this view, Filipinos actively participate to achieve this purpose by introducing malunggay (Moringa oleifera) as an important source of not only nutrition and medicine but of electricity as well. Malunggay is a tree that preferably grows in countries with tropical climate such as the Philippines. This tree can be easily propagated since malunggay can be grown from seeds or mature stem cuttings. In the country, this tree is commonly found in household backyard, aligned with perimeter fences, since the edible and nutritious flowers, fruits, and leaves of malunggay are part of the diet of Filipinos. Aside from the nutritional value of some parts of malunggay, all parts of this tree are used in herbal medicine to cure some diseases. Given that this tree can serve several purposes, malunggay becomes in demand. In light of the discussion of the environmental problems and characteristics of malunggay, a group of researchers conducted a study entitled MOB Electricity: Malunggay Bark Extract as Alternative Source of Electricity, to show that malunggay (Moringa oleifera) bark extract is a viable alternative source of electricity; consequently, providing an environment friendly, inexpensive and accessible source of electricity. At this point in time, since there is a strong desire to improve way of living, great attention is given to technologies. Due to this interest, innovations and inventions which require electricity are continuously developed. Thus, electricity must be continuously generated. On the contrary, most of the processes and materials for electricity generation pose hazards to the environment and human health. Therefore, a clean, low cost, and readily available source of electricity is needed, a reason that motivated the researchers to engage in this investigatory project. B. Statement of the Problem This study entitled MOB Electricity: Malunggay Bark Extract as Alternative Source of Electricity intends to investigate the feasibility of Malunggay (Moringa oleifera) bark extract as an alternative source of electricity. Specifically, this study sought to answer the following questions: 1. Is there a significant difference on the amount of voltage measured from liquid form of malunggay bark extract obtained through crude and ethanol extraction? 2. Is there a significant difference on the amount of voltage measured from jelly form of malunggay bark extract obtained through crude and ethanol extraction? 3. Is there a significant difference on the amount of voltage measured from liquid and jelly form of malunggay bark extract obtained through crude and ethanol extraction? 4. Is there a significant difference on the amount of voltage measured from varying amounts of malunggay bark extract? C. Hypotheses 1.

Ha: There is a significant difference on the amount of voltage measured from varying amounts of malunggay bark extract. D. Significance of the Study This study will provide the energy sector in the country a green alternative source of electricity which will reduce the use of materials that have hazardous effects to human and environment. Hence, minimizing occurrences of diseases and slowing the rate of environment degradation. Furthermore, the positive result of this study could also assure people with inexpensive and accessible source of electricity. Moreover, this study introduces a new application of malunggay, thus, further increasing the demand for this tree. In this effect, farmers in the country could have extra income by providing the needed supply of malunggay. E. Scopes and Limitations The focal point of this study is the feasibility of malunggay (Moringa oleifera) as an alternative source of electricity. In order to assess the said feasibility, malunggay bark extract obtained through crude and ethanol extraction was utilized. Subsequently, voltage was measured for different set-ups and treatments. However, the researchers were unable to determine the component of the extract responsible for electricity generation since the material was not subjected to chemical analysis. This restriction might be an additional recommendation for future researches. The researchers conducted this study from January 9, 2012 to August 23, 2012. All experiments and observations were done at JICA laboratory of Sapang Palay National High School. F. Operational Definition of Terms Gelatin Powder used to create a firm form of extract. Carbon Rod -served as the positive electrode (anode) of the external circuit connected to malunggay bark exract. Zinc Plate served as the negative electrode (cathode) of the external circuit connected to malunggay bark extract. Multi-tester used to measure the amount of voltage from malunggay bark extract. CHAPTER II REVIEW OF RELATED LITERATURE I. Introduction In the onset of the 21st century, negative effects of environmental issues such as pollution, ozone depletion, and global warming become notable. Thus, these problems gained the attention of people around the world. Among these negative effects are development and widespread of diseases, development of skin cancer, increase in temperature, heavy rains, heavy floods, strong typhoons, and climate change. In response, organizations are created, and conventions and researches are conducted to deal with these issues. Today, as data are continuously gathered;various human activities that involve emission of gases, chemicals, and radiations are considered as one of the large contributor to environmental degradation. Such human activities include generation of electricity. However, since electricity is vital in operating technologies which advances human lives, search for clean alternative source of electricity should be conducted to prevent further degradation of the environment. II. Electricity Generation Electricity is the form of energy that has the highest demand at this point in time. This energy form is required to operate technologies that people created for life advancement. Thus, energy industries are in continuous search to supply the needed demand of electricity. Today, there are different sources from which this energy is derived. These sources include fossil fuels (petroleum and coal), nuclear energy, hydropower, solar energy, and wind energy. These sources are used to drive turbines in electric power plants which will generate electricity. Electricity generated from these sources is the one supplied in wall sockets of houses and buildings. Another source of electricity is battery, a source that is in portable form. (Bose, 2010) In the Philippines, a country that is abreast with technologies, majority of the required electricity is derived from electric power plants that are run by fossil fuels such as petroleum and coal. Moreover, batteries which are portable source of the said energy are also in use. However, emissions from such electric power plants are composed of gases which cause air pollution and contribute to global warming. Likewise, batteries have chemical components that can leak and pollute land, water and air. In addition to these negative effects to the environment, human can also acquire diseases due to said contamination. (Petrina, 2007) III. Green Electricity People are now aware of the harmful effects of conventional electricity generation to human health and environment. Consequently, efforts and time are spent in order to discover alternative green clean, natural, biological sources of electricity, an action that would minimize presence of harmful chemicals and gases in the environment. In connection to this notion, researchers have considered different plants, different parts of plants, and organisms as potential source of green electricity. (U.S Environmental Protection Agency, 2012) Basic example of green energy is electricity from fruits and vegetables. Many people, during childhood, have done classroom experiments to derive electricity from lemon and potato. Results of these experiments proved that these materials can generate electricity because juices of fruits and vegetables act as electrolytes which initiate reaction to free and move electrons. (Renico, 2012) On the other hand, another related research was conducted by scientists of Stanford University which harness electricity from algae. The concept behind this project is the process of photosynthesis involved in food production of plants. According to the scientists, in this process, electrons from water are given with high energy by sunlight. These electrons are the one the scientists captured using electrodes. (Stanford University, 2010) Lastly, researchers of Arizona State University study the possibility for bacteria to generate electricity through the use of a microbial fuel cell (MFC) which contains waste water and bacteria dwelling on the material. In this research, the persons involve relate electricity generation to metabolic activity of bacteria. (Arizona State University, 2008) IV. Malunggay Tree Malunggay (Moringa oleifera) tree, which commonly grows in tropical countries such as Philippines, is characterized by long, straight, white trunks; small, green, compound leaves; and seasonal white flowers that yields long pods. This tree propagates easily and does not require much attention. In fact, malunggay seeds or matured stem cuttings can be planted in any kind of soil and does not require regular maintenance. (Asia Green Group, 2012) In the Philippines, malunggay can be found in most household backyards because edible parts of this tree (flowers, pods, and leaves) are part of Filipino cooking. Moreover, these parts of malunggay tree provide people with vitamins and minerals needed by the body. Aside from providing nourishment, this tree also has medicinal value. Based on numerous studies, malunggay contains chemicals that have antibacterial, anticancer, and anti-inflammatory properties. (Fahey, 2005) CHAPTER III METHODOLOGY Gathering of Materials/Equipments Among the materials gathered by the researchers were malunggay (Moringa olifera) bark, gelatin powder, ethyl alcohol, filter paper, gloves, face mask, and old batteries. Equipment as well was borrowed from the school laboratory. These equipments include beakers, reagent bottles, funnel, stirring rod, thermometer, mortar and pestle, alcohol lamp, triple beam balance, strainer, tripod, and wire gauze. Collection of Zinc Plate and Carbon Rod Researchers collected old batteries. Subsequently, these batteries were uncovered and electrolyte inside was removed. Since electrolyte component of battery is composed of slightly toxic chemicals, researcher wore gloves and face mask. In this manner, zinc plates and carbon rods were obtained. Preparation of Malunggay Bark Extract A. Crude Extraction Malunggay barks were collected and cut into small pieces by the researchers. Afterwards, the barks were placed in a blender. Finally, in order to obtain pure extract, minced barks were placed in soft cloth and squeezed. B. Ethanol Extraction Malunggay barks were collected and cut into small pieces. Then, barks were placed in a blender to mince the material. Next, minced barks were oven-dried for 5 minutes and were pulverized with mortar and pestle. After this process, 100 grams of pulverized bark was placed in a reagent bottle in which 250 ml of ethyl alcohol was poured afterwards. Lastly, extract which was rested for 10 hours for purification purpose was filtered through a funnel with filter paper. Varying the Amount of Bark Extract Amount of bark extract obtained through crude and ethanol extraction was varied for each treatment. 5 ml of extract was allotted to Treatment I, 10 ml for Treatment II, and 15 ml for Treatment III. Preparation of Jelly Form of Malunggay Bark Extract In a beaker, constant volume (5 ml) of water was poured and heated to 70oC. When water reaches the specified temperature, constant amount (10 g) of gelatin powder was added into the water. Then, the solution was continuously stirred. Before the solution solidifies, the assigned amount of extract per treatment was poured without stopping the stirring process. Material was immediately removed from heat. Measuring Voltage Zinc plate and carbon rod were installed to each treatment. From these electrodes, multitester was connected to measure voltage. Measurement was done for five times. Subsequently, voltage measured from each treatment was recorded.

CHAPTER V SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS Summary: This study entitled MOB Electricity: Malunggay Bark Extract as Alternative Source of Electricity aspires to prove if malunggay bark extract could be a possible source of electricity and to ascertain if there would be a significant difference when the method of extraction, form of extract, and amount of extract are varied. In order to test the feasibility of malunggay bark extract as alternative source of electricity, the researchers prepared two different set-ups and under each set-up there are three treatments. For the second set-up, amount of gelatin powder and amount of water used in each treatment were controlled. Then, voltage was measured in each treatment per set-up for five times using a multi-tester. The results obtained from different set-ups were analyzed using Two-Factor ANOVA with Replication. The results are summarized as follows: On the first set-up, statistical analysis showed that there is significant difference in the amount of voltage measured from liquid form of malunggay bark extract when method of extraction and amount of extract were varied. On the second set-up, statistical analysis showed that there is significant difference on the amount of voltage measured from jelly form of malunggay bark extract when obtained through different extraction method. Furthermore, statistically significant difference also exists on the amount of voltage reading when the amount of said form of extract was varied. Statistical analysis of Tables 3.0 and 3.1 indicate that there is significant difference on the amount of voltage measured when the form of extract and amount of extract were varied. Conclusion: Based on the results of statistical analysis and observations, the researchers conclude that malungggay bark extract could be a viable alternative source of electricity. Moreover, the people behind this study were able to discover that the 15 ml liquid form of extract obtained through crude extraction yielded the highest and most stable amount of voltage among all the treatments done. Recommendations: In this study the researchers encountered some hindrances which limited the scope of the investigation. Hence, only test for the feasibility of malunggay bark extract as an alternative source of electricity was conducted. Nonetheless, the study does not end with this objective. There are other factors related to electricity generation in malunggay bark extract that should be considered. Researchers would like to propose the following to other people who consider pursuing this project: Further increase volume of extract in order to obtain higher voltage reading. Convert the extract in a form that will facilitate easier and more stable voltage measurement. Subject the extract to chemical analysis to determine the component responsible for electricity generation. Develop a way to harness electricity from the extract.

Deception Point Page 41

Making the raging river of air even more unnerving to Tolland was the slight downwind grade of the ice shelf. The ice was sloped ever so slightly toward the ocean, two miles away. Despite the sharp spikes on the Pitbull Rapido crampons attached to his boots, Tolland had the uneasy feeling that any misstep might leave him caught up in a gale and sliding down the endless icy slope. Norah Mangor's two-minute course in glacier safety now seemed dangerously inadequate. Piranha Ice ax, Norah had said, fastening a lightweight T-shaped tool to each of their belts as they suited up in the habisphere. Standard blade, banana blade, semitubular blade, hammer, and adze. All you need to remember is, if anyone slips or gets caught up in a gust, grab your ax with one hand on the head and one on the shaft, ram the banana blade into the ice, and fall on it, planting your crampons. With those words of assurance, Norah Mangor had affixed YAK belay harnesses to each of them. They all donned goggles, and headed out into the afternoon darkness. Now, the four figures made their way down the glacier in a straight line with ten yards of belay rope separating each of them. Norah was in the lead position, followed by Corky, then Rachel, and Tolland as anchor. As they moved farther away from the habisphere, Tolland felt a growing uneasiness. In his inflated suit, although warm, he felt like some kind of uncoordinated space traveler trekking across a distant planet. The moon had disappeared behind thick, billowing storm clouds, plunging the ice sheet into an impenetrable blackness. The katabatic wind seemed to be getting stronger by the minute, applying a constant pressure to Tolland's back. As his eyes strained through his goggles to make out the expansive emptiness around them, he began to perceive a true danger in this place. Redundant NASA safety precautions or not, Tolland was surprised the administrator had been willing to risk four lives out here instead of two. Especially when the additional two lives were that of a senator's daughter and a famous astrophysicist. Tolland was not surprised to feel a protective concern for Rachel and Corky. As someone who had captained a ship, he was used to feeling responsible for those around him. â€Å"Stay behind me,† Norah shouted, her voice swallowed by the wind. â€Å"Let the sled lead the way.† The aluminum sled on which Norah was transporting her testing gear resembled an oversized Flexible Flyer. The craft was prepacked with diagnostic gear and safety accessories she'd been using on the glacier over the past few days. All of her gear-including a battery pack, safety flares, and a powerful front-mounted spotlight-was bound under a secured, plastic tarp. Despite the heavy load, the sled glided effortlessly on long, straight runners. Even on the almost imperceptible incline, the sled moved downhill on its own accord, and Norah applied a gentle restraint, almost as if allowing the sled to lead the way. Sensing the distance growing between the group and the habisphere, Tolland looked over his shoulder. Only fifty yards away, the pale curvature of the dome had all but disappeared in the blustery blackness. â€Å"You at all worried about finding our way back?† Tolland yelled. â€Å"The habisphere is almost invisi-† His words were cut short by the loud hiss of a flare igniting in Norah's hand. The sudden red-white glow illuminated the ice shelf in a ten-yard radius all around them. Norah used her heel to dig a small impression in the surface snow, piling up a protective ridge on the upwind side of the hole. Then she rammed the flare into the indentation. â€Å"High-tech bread crumbs,† Norah shouted. â€Å"Bread crumbs?† Rachel asked, shielding her eyes from the sudden light. â€Å"Hansel and Gretel,† Norah shouted. â€Å"These flares will last an hour-plenty of time to find our way back.† With that, Norah headed out again, leading them down the glacier-into the darkness once again. 47 Gabrielle Ashe stormed out of Marjorie Tench's office and practically knocked over a secretary in doing so. Mortified, all Gabrielle could see were the photographs-images-arms and legs intertwined. Faces filled with ecstasy. Gabrielle had no idea how the photos had been taken, but she knew damn well they were real. They had been taken in Senator Sexton's office and seemed to have been shot from above as if by hidden camera. God help me. One of the photos showed Gabrielle and Sexton having sex directly on top of the senator's desk, their bodies sprawled across a scatter of official-looking documents. Marjorie Tench caught up with Gabrielle outside the Map Room. Tench was carrying the red envelope of photos. â€Å"I assume from your reaction that you believe these photos are authentic?† The President's senior adviser actually looked like she was having a good time. â€Å"I'm hoping they persuade you that our other data is accurate as well. They came from the same source.† Gabrielle felt her entire body flushing as she marched down the hall. Where the hell is the exit? Tench's gangly legs had no trouble keeping up. â€Å"Senator Sexton swore to the world that you two are platonic associates. His televised statement was actually quite convincing.† Tench motioned smugly over her shoulder. â€Å"In fact, I have a tape in my office if you'd like to refresh your memory?† Gabrielle needed no refresher. She remembered the press conference all too well. Sexton's denial was as adamant as it was heartfelt. â€Å"It's unfortunate,† Tench said, sounding not at all disappointed, â€Å"but Senator Sexton looked the American people in the eye and told a bald-faced lie. The public has a right to know. And they will know. I'll see to it personally. The only question now is how the public finds out. We believe it's best coming from you.† Gabrielle was stunned. â€Å"You really think I'm going to help lynch my own candidate?† Tench's face hardened. â€Å"I am trying to take the high ground here, Gabrielle. I'm giving you a chance to save everyone a lot of embarrassment by holding your head high and telling the truth. All I need is a signed statement admitting your affair.† Gabrielle stopped short. â€Å"What!† â€Å"Of course. A signed statement gives us the leverage we need to deal with the senator quietly, sparing the country this ugly mess. My offer is simple: Sign a statement for me, and these photos never need to see the light of day.† â€Å"You want a statement?† â€Å"Technically, I would need an affidavit, but we have a notary here in the building who could-â€Å" â€Å"You're crazy.† Gabrielle was walking again. Tench stayed at her side, sounding more angry now. â€Å"Senator Sexton is going down one way or another, Gabrielle, and I'm offering you a chance to get out of this without seeing your own naked ass in the morning paper! The President is a decent man and doesn't want these photos publicized. If you just give me an affidavit and confess to the affair on your own terms, then all of us can retain a little dignity.† â€Å"I'm not for sale.† â€Å"Well, your candidate certainly is. He's a dangerous man, and he's breaking the law.† â€Å"He's breaking the law? You're the ones breaking into offices and taking illegal surveillance pictures! Ever heard of Watergate?† â€Å"We had nothing to do with gathering this dirt. These photos came from the same source as the SFF campaign-funding information. Someone's been watching you two very closely.† Gabrielle tore past the security desk where she had gotten her security badge. She ripped off the badge and tossed it to the wide-eyed guard. Tench was still on her tail. â€Å"You'll need to decide fast, Ms. Ashe,† Tench said as they neared the exit. â€Å"Either bring me an affidavit admitting you slept with the senator, or at eight o'clock tonight, the president will be forced to go public with everything-Sexton's financial dealings, the photos of you, the works. And believe me, when the public sees that you stood idly by and let Sexton lie about your relationship, you'll go down in flames right beside him.†

Earthquake Sichuan

In May 2008, a memorial tragedy has carved our heart. More than 60,000 of our compatriots died in the Great Sichuan Earthquake. It was a once-in-a-year strong earthquake registering a magnitude of 7. 8 measured in the Richter scale. The province where the earthquake took place, Sichuan, is in western China and its capital is named Chengdu. It is surrounded by the Sichuan Basin. In the Great Sichuan earthquake, the epicenter was in Wenchuan County, Ngawa Tibetan and Qiang Autonomous Prefecture, which is 80 km north-west of Chengdu; and its depth was 19 km. On May 12, 2008, the earthquake occurred at 14:28 (China Standard Time) and the first tremor was felt. The earthquake was so strong that it was felt by cities like Beijing and Shanghai, and neighbour places like Hong Kong, Macau, Vietnam and Thailand also experienced tremors. The scope of the areas affected by the quake mainly included the north-east China along the Longmen Shan fault. The Sichuan Basin was created 55 millions years ago, where the Indo-Australian Plate collided with the Eurasian Plate. These endogenetic forces create fold mountains, and therefore the Sichuan basin is bounded by mountains on all sides. As a consequence, areas around the Sichuan Basin are prone to earthquake. In 1933, there was a 7. 5-magnitude earthquake occurring in north-west of Sichuan, causing 7500 deaths. What has caused such a massive earthquake? To be precise, according to the United States Geological Survey, the earthquake occurred because of the motion on a northeast striking reverse fault on the northwestern edge of the Sichuan Basin. Since the crustal materials moved slowly from the high Tibetan Plateau, when they flowed to the strong crust underlying the Sichuan Basin and southeastern China, pressure gradually developed. The energy was then released in the form of seismic waves and thus led to the occurrence of the earthquake. Another possible cause is that the huge amount of water storage in reservoirs in Sichuan developed stress over the crust. The pressure stored may be released, causing an earthquake. There were not any official warnings prior to the main quake. This is attributed to the fact that earthquakes are hard to forecast, and the results are not always accurate. However, it is said that there was a sign revealing the earthquake: a large number of toads were migrating in Sichuan two days before the main quake. These animals’ abnormal acts may reflect in earthquake events. In the Sichuan Earthquake, the China Earthquake Administration did not find strong evidence to show that an earthquake was to be occurred. Therefore, when the earthquake came, evacuation could not be made effective and thus a huge damage was resulted. Then on 12 May, an earthquake indeed struck the area. The main quake of the Sichuan Earthquake took place at 14:28 local time, nevertheless, the rupture lasted for only 120 seconds. In the following three days, many aftershocks still threatened the people. There were 64 to 104 major aftershocks, with magnitude ranging from 4. 0 to 6. 1. These aftershocks continued to bring new deaths and casualties in the area. For example, on 17 May, an aftershock destabilized a slope and caused a landslide. On 25 and 27 May, the Qingchuan County had two aftershocks on the spot with magnitudes greater than 5. On 27 May again, an aftershock hit the Ningciang County. Till 29 June, the number of deaths has reached about 70,000 and over 370,000 people were injured. More than 17,000 people were missing, and many people were made homeless. More than 15 million people must be evacuated out of the area, and about 45 million people were affected by the incident. As a recent natural hazard, the Sichuan Earthquake is definitely a severe one, with a tremendous destruction. This earthquake caused the most serious casualties and deaths after the occurrence of the Tangshan Earthquake in 1976. Apart from the loss of lives, the earthquake brought about many impacts as well. The impacts can be divided into three aspects, namely social, economic, and environmental. First, 0. 21 million of buildings and houses were collapsed, including 7,000 schools. Many people lost their homes, and students lost their opportunity of education for a period of time. Later it was found that some buildings were too loosely structured; partly because of corruption. Some workers did not do their best to build the buildings. In addition, the communication network was destroyed. In Sichuan, Chongqing and Huabei, the communication was completely jammed. The traffic network was also disrupted. Many highways or railways were cracked due to great vibrations, and the international airport in Chengdu was closed. The roads must be closed for maintenance. These have led to difficulty in relief work. Finally, some victims of the earthquake stole or robbed stuff. After the earthquake, there were more crimes committed by the victims. On the other hand, the Sichuan Earthquake brought environmental issues. In the affected areas, clean water was inadequate. When people had to drink contaminated water, illnesses or diseases may be developed. Also, in the areas, corpses were everywhere and we know how unhygienic it was! Together with the warm temperature, the filthy place set up a good condition for diseases to spread. To make the affected areas more hygienic, the death bodies must be incinerated, and cleaning agents like insecticides must be sprayed regularly. Meanwhile, the affected areas were heavily polluted. The earthquake initiated poisonous gas leakage, explosions or fires, which in turn polluted the air. The ecology was disrupted as well. On the economic aspect, the disastrous events led to huge economic losses. The government used more than $400 billion for relief and rescue work. The Shanghai Stock Exchange and Shenzhen Stock Exchange lost connection with Sichuan and Chengdu companies, the companies’ stock prices dropped substantially afterwards. Owing to fact that the earthquake has destroyed Sichuan so terribly, prompt relief and rescue work was crucial. The mitigation work involved the efforts of local government, regional and international aid. The central government sent different leaders to the affected areas to manage relief work. On 14 May, two days after the main quake, more than 11,000 people participated to give assistance to the suffered people. A team of medical helpers was sent to deal with health problems. The government also kept necessities and rescue materials which are to be sent to the victims. Different departments cooperate to restore Sichuan’s face. Until 18 May, more than 110,000 military personnel and policemen were sent to participate in rescue work. They saved thousands of lives, evacuated tourists and residents, repaired the highways and transferred materials to the affected victims. This devastating earthquake has called for help from all over the world. In Hong Kong, Macau and Taiwan, the voluntary or charity organizations held many fund-raising campaigns to raise money or food to the Sichuan people. Even in the initial state of mitigation, the Hong Kong and Macau governments donated 0. 2 billion to China. Many helpers like policemen were also sent to Sichuan to help mitigation work. Apart from regional help, the earthquake victims gained help from international aids. For instance, Valley Tsinghua Network (SVTN) set up the â€Å"China Earthquake Relief Fund† to help victims involved in the massive earthquake. This China Relief Fund provided a convenient platform for individuals, organizations to donate money to the victims, where all proceeds went to the Red Cross Society of China to help restoring the infrastructure in Sichuan. Many countries including India, Singapore, Russia, America and Japan provided China materials, money, apparatus and services to search for lives and help the suffered ones. Some volunteered professionals reached Sichuan to give education to the children, to soothe the suffered people and to give counseling and care to them. The victims’ emotions must be calmed down to prevent emotional disorders. It seems that the Sichuan Earthquake had a perfect solution with the aids of different parties. In fact, there were many difficulties encountered in rescue work. After an earthquake, the immediate step is to save as many lives as possible. The first 72 hours are golden times. The Sichuan Earthquake, however, occurred in mountainous regions where relief efforts were hindered by the landscape. Added to the above, the transfer of materials was difficult because of blocked roads and water transports. The visibility was lowered as a consequence of heavy rains; thus the people could not find the survivors easily. As a result, the rescuers could not reach in time, and there were still a large number of deaths. As seen from the human responses, the earthquake has caught global attention and acquired help and assistance from people. But this still cannot redeem the lost lives. What are the lessons learned through this disaster? Since earthquakes give little warning in advance, the ultimate efforts should be put to mitigation and preparedness. The government has endeavored to pin down the number of deaths and casualties after the earthquake, but what about preparedness? Residents should be well educated about earthquake facts. They should know what to do when an earthquake indeed hits the area. Besides, preparedness includes recruitment of specialized and skillful rescue teams in case of an incidence of earthquake. Transport and communication networks should always be maintained. The apparatus used in rescuing people can be improved by means of technology. Finally, the government can also â€Å"prepare† by inspecting the quality of buildings. Construction codes have been modified to reinforce the buildings in order to cope with earthquakes. However, the privately-built housings were not reported. Therefore, buildings with bad quality are likely to demolish when earthquakes hit. It was mentioned above that the Sichuan Earthquake is the most disastrous one following the Tangshan Earthquake. In fact, both quakes have similar magnitudes and depths of epicenter. With a mountainous range in Sichuan, relief effort is difficult because the affected areas are hardly reached, and the materials are hardly transferred. So why did the Tangshan Earthquake cause much more deaths than the Sichuan one? The prime reason is that China restricted the spread of the news of Tangshan Earthquake, thus rejected help from others. As mentioned above, the suffered people in Sichuan Earthquake received many aids from all over the world. The mitigation was much better for the latter event. Thanks to everyone who has paid an effort to help the victims in Sichuan. Natural hazards are inevitable. It is heartbroken that the people lose their homes, their family or their beloved ones. To bring minimal loss after a disaster, all of us must cooperate to give help. It is glad to see that all people were giving a hand to the Sichuan victims, and it is nice to see that Sichuan today is recovered. The Sichuan Earthquake has given us a precious lesson: what we should do today is prepare for the worst, and when another outraging disaster strikes, we shall do our best to counteract it.

Who s Harassing Whom - 976 Words

Marianne Jennings in â€Å"Who’s Harassing Whom?† writes, about her stand on women and sexual harassment. She adopts a stern and passionate tone in order to convince the audience of the responsibility women bear for being harassed. Jennings’s purpose is to highlight how some women bear part of the blame in the matter by choosing to stay in situations where they are the recipients of unwanted advances, because of personal ambition. Jennings in â€Å"Who’s Harassing Whom?† furthers her purpose by employing ethos, pathos, and logos to support her argument. In her article regarding sexual harassment, Jennings employs ethos in order to establish her character and credibility to lay a foundation to support her point of view. She seeks to persuade the†¦show more content†¦The writer appeals to logic by posing a rhetorical question to the audience, â€Å"how innocent are the victims of harassment anyway?† (256) when referring to women, allegedly harassed by their supervisor, at the â€Å"Ford plant in Chicago† (256). The writer states â€Å"they tearfully told of sleeping with their supervisors to keep their jobs† in order to show that women choose to sleep with their bosses instead of getting another job. Another way that Jennings supports her argument is by anticipating objections from the audience. She offers supporting evidence to counter the opposing view â€Å"either I stay here and get harassed †¦or leave and take another job for less pay† (256), in order to show that some women stay because money is more important than their â€Å"virtue† (256). The writer points out that people who think of sexual harassment in terms of money over their safety are people who make poor decisions. It seems that â€Å"$22.00 an hour† (256), the hourly pay at the Ford plant, is a good enough reason to put up with sexual advances. Through Jennings’s employment of logic, she successfully shows that women at the receiving end of sexual harassment are making flawed decisions by staying merely because of financial reasons. As a result, the writer suggests that women bear some responsibility by staying. Similarly, Jennings employs pathos in her article to appeal to the emotions of the reader to support her argument by citing a high-profile case and by using highlyShow MoreRelatedCyber Bullying Has Been Overlooked By Many Schools1383 Words   |  6 Pagesbeing done to the victim.
