Waves lab Research question How do optically different liquids ( in this experiment vinegar, water, coke, oil ), change the angle of refraction on a single laser ray? Independent variable In this experiment I will compare vinegar, water, coke and oil. Dependent variable Angle of the laser ray that will be refracted in the experiment. Controlled variable To make the experiment fair, I need to control the temperature of the liquids. Because if the temperature is changing, the solubility will change
percent of the plastic originates from land; floating in rivers to the ocean or blew by the wind into the ocean. The remaining twenty percent of the plastic originates from oil platforms and ships (Facts). The Great Pacific Garbage Patch should be reduced by the following three ways: reduce plastic use, eat less harvested fish, and participate in beach cleanups. Many people in the world uses plastic, without it, life would be less convenient. A lot of people don’t realize how plastic is affecting
Swordfish (Xiphias gladius) are apex predators considered to be pandemic and migratory species that are found in larger quantities in the Atlantic, Pacific, and Indian Oceans. In this paper, secondary data were collected to investigate the diet of those found in the Northeast Atlantic Ocean. The results indicated that they ate prey from different species of fishes, cephalopods, and crustaceans. Their lives are threatened by pollution, and bycatch in tuna longlines, however they will continue to exist
is 100% organic product. 1.8.3 Economic Benefits of Biodiesel The biodiesel can be extracted from any material that contains fatty acids. The various vegetable fats and oils, animal fats, waste greases and edible oil processing wastes can be used as feedstock for the production of biodiesel. The future needs for imported oil to manufacture regular diesel fuel could be reduced by the significant use of biodiesel. The cost of biodiesel is most likely to remain stable than fossil fuel costs in future
Water pollution is a serious problem that we have to deal with everyday in our lives. Water pollution can affect the lives of many as we as humans depend on water to live. Water Pollution: What is it and where is it taking place? Water pollution is the contamination of water bodies such as lakes, rivers, oceans, dams etc. (https://en.wikipedia.org/wiki/Water_pollution). It is also any chemical, physical or biological change in the quality of water that has a harmful effect on any living thing
This expression was through Robert Flaherty and his film, Man of Aran. ETHNOGRAPHY In an area such as the Aran Islands, an area shrouded in mystery and tradition, it is not surprising that numerous creators of literary or poetic works have used research styles rooted in the social sciences, primarily the use of ethnography and narrative inquiry methods, or some combination of them. Ethnography is the holistic study of people, races, and cultures, as a basis to collect data and information for their
the air. A source of carbon dioxide is the burning of fossil fuels, which is being balanced by the photosynthesis of plants. The carbon from burning excessive amounts of fossil fuels is absorbed by trees in the environment. These fossil fuels include oil, coal, and natural gas. When burned, they emit carbon and release it into the air. Humans have been burning vast quantities of fossil fuels which release the carbon they contain as carbon
problem. With all the waste that humanity flush out to the sea, this is now consider a major world crisis for it deadly effects. Many of the waste that are flowing around in the ocean are chemically makeup. Example would includes plastic debris, crude oil from underground and many other man-made waste product. But let first discuss about plastic debris, for it’s the most common type of man-made chemical make up material that is popular in every aspect of the human life. And as a famous naturalist comments
The Hazard Assessment method used in the paper was the globally acknowledged PEC and PNEC approaches according to Basietto et al., 1990. PEC stands for the acronym of Predicted Environmental Concentration whereas the PNEC stands for Predicted No Effect Concentration. This method uses the ratio
INTRODUCTION Business gradually more finds that they have to rely on efficient supply chains, or system, to effectively compete in the worldwide market and network economy. Through the precedent decades, globalization, outsourcing and information knowledge have facilitate many group, example as Dell and Hewlett Packard, to effectively operate solid joint supply networks in which every specialized company partner focus on simply a few key strategic actions (Scott, 1993). so, the choice of an internal
