America’s Foreign Oil Dependency: What are the options to stop this crisis? For Professor Sharon Mitchener From August 11‚ 2006 BUS 531 Research Proposal Abstract The topic of this paper is America’s foreign oil dependency. The purpose of this paper is to suggest how might America completely destroy or at least greatly mitigate its dependency on crude oil to fuel Americans’ cars‚ especially foreign crude oil.

biodiesel get thirty percent better fuel economy than gasoline-powered vehicles (Perritano). The many forms of biofuels make it easier to obtain and use. Biofuels are better for the environment because they reduce greenhouse gas emissions. For example‚ ethanol reduces greenhouse gas emissions up to sixty-five percent (Perritano). Biofuels are a source of energy from plants that can help fuel our vehicles and our lives. A biofuel is any fuel that is made from plant material. Many biofuels can replace diesel

germinated seeds decreased with higher concentrations of fuel. In addition‚ biodiesel was also synthesized and its heat of combustion was found through the use of calorimetry. The heat capacity for the calorimeter was based on the heat of combustion for ethanol‚ which was then used to determine the heat of combustion for biodiesel. The average heat of combustion for biodiesel was ∆Hcomb= -13090.83 kJ/mole‚ as opposed to the theoretical value of -11496.6 kJ/mole‚ which resulted in a 13.9% difference. Furthermore

WTHESIS STATEMENT: “BIOCONVERSION OF WATER HYACINTH (EICHHORNIA CRASSIPES) TO ETHANOL.” 1. INTRODUCTION Water hyacinth (Eichhornia crassipes) is a free-floating or rooted in mud plant or weed which can totally cover fresh water lakes‚ harbors‚ and other essentially relatively occluded fresh water bodies. It is a fast growing permanent aquatic plant that are extensively scattered all throughout the world. This tropical plant can be the reason for the infestation over large areas of water resources

of a suspect. The proposed research of this paper focused on insects being affected by different concentrations of ethanol during natural insect development and also focused on the detection of ethanol in insects using gas chromatography mass spectrometry (GCMS) to determine if insects were significantly affected by ethanol exposure. The research also focused on the exposure of ethanol to the insects and how this exposure affected PMI (postmortem interval) determination. Forensic entomology is a commonly

Association The Impact of the Oil Sector on Commodity Prices: Correlation or Causation? Sayed H. Saghaian The interconnections of agriculture and energy markets have increased through the rise in the new biofuel agribusinesses and the oil–ethanol–corn linkages. The question is whether these linkages have a causal structure by which oil prices affect commodity prices and through these links‚ instability is transferred from energy markets to already volatile agricultural markets. In this
