... Significance of the Study With two-thirds of the earth’s surface covered by water and human body consisting of 78% of it. It is evidently clear that water is one of the prime elements responsible for life on earth. It is necessary for the digestion and absorption of food, help maintain proper muscle tone and supply oxygen and nutrients to cell (Quiles and Quiles, 1996). A drinking water is defined as water intended primarily for human consumption but which has another domestic purposes. It may consume directly from the tap for beverages and food prepared with water. But according to Hippocrates, water supplies may also be contaminated with organisms that can cause disease. Among diseases that may transmitted by water contaminated by bacteria, viruses or protozoa are typhoid and cholera, gastroenteritis, paratyphoid fever, and infectious hepatitis. These kinds of diseases are caused by microbiological parameter. One of the microbiological parameter is the coliform bacteria. Coliforms may be associated with the sources of pathogens contaminating water. It is a broad class of bacteria found in our environment, including the faeces of man and other warm-blooded animals. The presence of coliform bacteria in drinking water may indicate a possible presence of harmful causing disease. Purok Cueva is one of the Puroks comprising Barangay of Pisan. The source of the said Purok is a well. Water taken from well for human consumption can be possible contaminated. According to Municipality...

Thus, the research questions were: (a) What were their thoughts about the moment when patients learned that they were infected? (b) To whom and when did patients disclose that they were infected? (c) How did they disclose the information? (d) How much or what information did they disclose, and what were the reactions of those who were informed? (e) Why did they reveal the information? The descriptive study was done using a convenience sample of 45 patients with HIV/AIDS at a hospital clinic in northeastern Thailand. The results showed that 67% told a family member, usually their mother, within...

Since natural disasters are already altering the way each Filipino live, every member of the society has the obligation of making a crucial decision whether: to act cooperatively now to address the problem, to prefer to move independently or to decide to be passive and suffer the consequences of apathy together (Aquino III, 2014). Advance preparation of the government with the community can possibly reduce the casualties due to natural calamities and incidents. Therefore, implementation of disaster management and risk reduction activities among the community to promote calamity preparedness in the Philippines requires a collaborative effort. Disaster risk reduction management aims to enhance the resiliency of the Filipino people through changing the country’s tendency of increasing figures and loss from natural calamities, developing safe and resilient communities and assuring a long-lasting development for the whole nation through the implementation of disaster risk reducing projects such as the education for basic human needs storage and survival strategies of the community that is backed up by the past projects of the Non-Government Organizations (NGOs). The implementation of disaster risk reduction...

The resources that we have used up from the environment have often been nonrenewable and in our heedless march to glorious comfort, we have ignored the consequences of the effect that we are having on the world we live in. With the results of our negative impact on nature coming around to haunt us, there have been a rising global awareness and movement to better ourselves. Green technology is a major part of it. Green technology is the application of the environmental science to conserve the natural environment and resources, and to curb the negative impacts of human involvement. The main idea behind green technology is to provide sustainable growth. That is, using resources from the Earth in a renewable fashion. The following report outlines some aspects of green technology and discusses three main ideas: Solar energy, Green Buildings, Biofuels. In the report, it has been discussed how each of these technologies are environmentfriendly, how...

...ENERGY Renewable Energy: An Overview DOE/GO-102001-1102 FS175 March 2001 EFFICIENCY AND RENEWABLE ENERGY What is Renewable Energy? Renewable energy uses energy sources that are continually replenished by nature—the sun, the wind, water, the Earth’s heat, and plants. Renewable energy technologies turn these fuels into usable forms of energy—most often elec- tricity, but also heat, chemicals, or mechanical power. Why Use Renewable Energy? Today we primarily use fossil fuels to heat and power our homes and fuel our cars. It’s convenient to use coal, oil, and natural gas for meeting our energy needs, but we have a limited supply of these fuels on the Earth. We’re using them much more rapidly than they are being created. Even- tually, they will run out. And because of safety concerns and waste disposal prob- lems, the United States will retire much of its nuclear capacity by 2020. In the mean- time, the nation’s energy needs are expected to grow by 33 percent during the next 20 years. Renewable energy can help fill the gap. Even if we had an unlimited supply of fos- sil fuels, using renewable energy is better for the environment. We often call renew- able energy technologies “clean” or “green” because they produce few if any pollutants. Burning fossil fuels, however, sends greenhouse gases into the atmos- phere, trapping the sun’s heat and con- tributing to global warming. Climate scientists generally agree that the Earth’s average temperature has risen in the past century...

...Title: SOLAR ENERGY: “SUNLIGHT into USEFUL ELECTRICITY” >Introduction< In today's climate of growing energy needs and increasing environmental concern, alternatives to the use of non-renewable and polluting fossil fuels have to be investigated. One such alternative is solar energy. Solar energy is quite simply the energy produced directly by the sun and collected elsewhere, normally the Earth. The sun creates its energy through a thermonuclear process that converts about 650,000,000 tons of hydrogen to helium every second. The process creates heat and electromagnetic radiation. The heat remains in the sun and is instrumental in maintaining the thermonuclear reaction. The electromagnetic radiation (including visible light, infra-red light, and ultra-violet radiation) streams out into space in all directions. Only a very small fraction of the total radiation produced reaches the Earth. The radiation that does reach the Earth is the indirect source of nearly every type of energy used today. The exceptions are geothermal energy, and nuclear fission and fusion. Even fossil fuels owe their origins to the sun; they were once living plants and animals whose life was dependent upon the sun. The sun is an inexhaustible source of energy. Solar energy is radiant energy from the sun caused by nuclear fusion in the sun’s core. The sun’s radiant energy reaches the earth in rays of sunlight. Solar energy in the form of heat and light sustains life on earth. Solar energy can...

...conserving water and energy, reducing waste and pollution, harnessing renewable energy sources, finding ways to reuse materials, and developing less polluting technologies. Green technology is everywhere these days; in the news, politics, fashion, and of course technology. Green Technology is becoming so widespread throughout the world. People are becoming more energy efficient in their homes by buying water-efficient showerheads that are low-flow models, adjusting their refrigerator and freezer temperatures, buying compact fluorescent light bulbs, buying energy efficient appliances, and by recycling rechargeable devices like cell phones or digital cameras. As awareness grows about environmental issues such as pollution, human impact on climate change, and depletion of natural resources, so is interest growing in environmentally friendly products and services. For example, the popularity of green cleaning products has increased in recent years. Nontoxic, biodegradable cleaning products are safer for use in the home meaning they are less likely to cause health problems. They also keep harmful chemicals out of the environment. Compact fluorescent light bulbs (CFLs) are another popular eco-friendly product; compared to traditional, incandescent light bulbs, CFLs use way less electricity. Here are a four of the many types of green technology used today; green energy, vehicles, building and appliances. Green energy as of today is produced by these forms of energy; solar, wind...

...Lloyd Alter Technology / Solar Technology September 21, 2010 Inhabitat calls it the "World's first solar powered air conditioning unit", as does the Shandong Vicot Air Conditioning Company. That is a rather grand statement, given that another Chinese company, BROAD, has been doing it for years , and there are direct solar powered air conditioners installed from Brooklyn to Dubai. From the looks of it and the description, it appears to be a direct-fired absorption system, where the reflector supplies heat that vaporizes a refrigerant, which absorbs heat when it condenses. Propane fridges work this way. According to SolarServer, "The company claims an 85% thermal cooling efficiency and the ability to deliver 24-hour continuous cooling, heating and hot water. If there is not enough sun, it can run on natural gas. Since the unit generates heat, it can also supply hot water and heating. Unfortunately, it does not appear to be sized for domestic use. More at Inhabitat If It's The First, What Are These? Solar Air Powered Air Conditioning Comes To Dubai One of the reasons we have been so dubious about Dubai is the energy consumption required to keep people cool there; they even air condition the beaches. But if there is one thing they have lots of, it is sunlight; that's why we have always considered solar powered air conditioning the holy grail that will make places from Dubai to Phoenix sustainable. 1.

...multiple forms of renewable energy. I will lay out the advantages and disadvantages of each form of renewable energy and how they affect people, wildlife, and our environment. The Law of Conservation of Energy The Law of Conservation of Energy states that the total amount of energy in an isolated system remains constant over time (is said to be conserved over time) although energy within the system can be changed from one form to another or transferred from one object to another (Law of Conservation, n.d.). This law applies to energy use in that we are taking a form of energy and changing it into a different form. We are not actually using up the energy but changing the form of it from one to another. An example of this can be solar energy. We take the energy from the sun and change it into usable energy for our homes, businesses, schools, and hospitals. This law also applies to energy conservation in that some energy is always wasted when being changed from one form into another. It is impossible to change energy without actually wasting some of it. In many energy conversions, more energy is wasted that is used for work such as automobile engines, they typically waste more than two-thirds of the total energy used, primarily through heat (Law of Conservation, n.d.). Fossil fuels such as oil, natural gas, and coal were formed many hundreds of millions of years ago before the time of dinosaurs, hence the name fossil fuels (Where Fossil Fuels Come From , 2012). Coal...

... is like the old people in the family of countries, while Russia, and other European countries are like the younger instyle kids. I made this connection because while we are still using fossil fuels, Russia for example are moving on to bigger things like solar panels. In Russia you can find solar panels all over the place. They have them on top of hospitals, houses, public buildings, just about everywhere. In the city of Krasnodar, they put a solar panel on top of the building to collect heat for their water. The solar collector system produces 10 m3 of hot water daily. The operational season is from the end of April until the end of September. The hot water in the pipe after the collectors heat it can reach 80°C in hot weather. The collectors are installed on the roof of the hospital's kitchen, and the water is used for cooking after some additional boiling powered by electricity. The system consists of 108 solar collector panels. A storage tank is used with these collectors to accumulate water and stabilize the supply. The drop in water temperature in the tank overnight is about 2°C. A pump is used to circulate water through the system. That just a taste of what they invested in. currently Russia is trying to put a solar panel in space to generate necessary power, yet we just have them on a couple of buildings and the lights for the streets. Another country that is ahead of us would be the English, and man over in England is supposed to have created an air powered...

...is electricity and heat generated from solar, wind, ocean, hydropower, biomass, geothermal resources, and biofuels and hydrogen derived from renewable resources.” Renewable energy resources and significant opportunities for energy efficiency exist over the world. Compare to other traditional energy resources like fossil fuel, which are concentrated in a limited number of countries. The rapid development of renewable energy and energy efficiency, and the technological diversification of energy resources, would provide a sustainable and stable supply of energy and a significant growth in economy for the world in a foreseeable future. History of Renewable Energy Prior to the development of coal in the mid 19th century, nearly all energy used was renewable. The oldest known use of renewable energy, in the form of traditional biomass to fuel fires, dates from 790,000 years ago (K. Kris, 2013). The second oldest usage of renewable energy is using the wild to drive ships over water. This can be traced back 7,000 years ago, to ships on Nile (The Encyclopedia of Alternative Energy and Sustainable Living, 2013). Moving into the time of recorded history, the primary resources of traditional renewable energy were human labor, animal power, water power, wind and firewood (traditional biomass). By late 19 century, people concerned of running out of coal, so they promoted experiments with using solar energy. The development of solar engine continued until...

...Electricity: What Powers Our Planet To Whom It May Concern: It’s dark and you are trying to sign paperwork. You want to turn on the lights so you can see better. With one flick, the whole room illuminates. But, congressman, let me ask you. Have you ever wondered how electricity works? What is it that makes electricity possible? What did it take for light to have the ability to stream out of the light bulb? We take electricity for granted, but not many of us actually look into it. People often do not know how electricity is the way it is, but instead they see electricity as something that is very accessible and plentiful. So, congressman, you have the money, and I have the brains. You want to know how to spend the 200 billion? I’ll tell you. Let’s start off with what electricity really is. You hear that word so many times in your daily life, but few have heard the scientific definition. Electricity is a type of energy produced from the existence of electrons or protons, either statically as a build-up of charge, or dynamically as a current. It is usually categorized into two different currents: alternating current (AC) and direct current (DC). Alternating current is a constant flow of electric charge that reverses its course from time to time. Direct current is the opposite; it only runs in one direction. Within those two currents are things such as volts, watts, amperes (or amps), and ohms. Volts are the SI unit of electromotive force, the distinction of potential that would...
