Modeling And Analysis Of The Spread Of Japanese Encephalitis With Environmental Effects, Ram Naresh, Surabhi Pandey Jun 2009

Modeling And Analysis Of The Spread Of Japanese Encephalitis With Environmental Effects, Ram Naresh, Surabhi Pandey

Applications and Applied Mathematics: An International Journal (AAM)

A nonlinear mathematical model for the spread of Japanese Encephalitis, caused by infected mosquito feeding on susceptible human population incorporating demographic and environmental factors is proposed and analyzed. In the modeling process, it is assumed that the growth rates of reservoir animal population and vector mosquito population are enhanced due to environmental discharges caused by human population related factors. The model is analyzed by stability theory of differential equations and computer simulation. Both the disease-free and the endemic equilibria are found and their stability is investigated. It is found that whenever the disease-free equilibrium is locally asymptotically stable, the endemic …


E-85 Vs. Regular Gasoline: Effects On Engine Performance, Fuel Efficiency, And Exhaust Emissions, Jordan W. Steinhaus, Donald M. Johnson, George W. Wardlow Jan 2009

E-85 Vs. Regular Gasoline: Effects On Engine Performance, Fuel Efficiency, And Exhaust Emissions, Jordan W. Steinhaus, Donald M. Johnson, George W. Wardlow

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

This study compared the performance, fuel efficiency, and exhaust emissions of a 2.61 kW engine fueled with regular unleaded gasoline (87 octane) and an 85% ethanol blend (E85) under two load conditions. Four 1-h tests were conducted with each fuel at both governor’s maximum (3400 rpm) and peak torque (2800 rpm) conditions for a total of 16 tests. At governor’s maximum engine speed, there were no significant differences (p>0.05) between fuels for engine torque, power, specific carbon dioxide (sCO2 ), specific carbon monoxide (sCO), specific hydrocarbons (sHC), or specific oxides of nitrogen (sNOX) emissions. However, there was a significant …


Dna Sequence Analysis Of Freshwater Eustigmatophyceae, A Potential Source Of Essential Fatty Acids, Sara E. Prior, M. W. Fawley, K. P. Fawley Jan 2009

Dna Sequence Analysis Of Freshwater Eustigmatophyceae, A Potential Source Of Essential Fatty Acids, Sara E. Prior, M. W. Fawley, K. P. Fawley

Journal of the Arkansas Academy of Science

Freshwater Eustigmatophyceae are a group of microalgae that are considered rare and of low diversity, with only a few genera and species in a single order. Some Eustigmatophyceae produce fatty acids that are important nutrients for aquaculture, as well as for human food consumption. In addition, some Eustigmatophyceae produce hydrocarbons that may be useful in biofuel production. In our studies of the diversity of coccoid algae from Itasca State Park, Minnesota, we discovered several isolates that we tentatively identified as Eustigmatophyceae. Preliminary molecular characterization indicated that these isolates were highly diverse and probably represented species new to science. In this …

Measurement Of Transient Smoke Emissions From Diesel And Biodiesel Fuel Blends In An Agricultural Tractor, Kristin M. Pennington, Sonia R. Munoz, Donald M. Johnson, George Wardlow Jan 2009

Measurement Of Transient Smoke Emissions From Diesel And Biodiesel Fuel Blends In An Agricultural Tractor, Kristin M. Pennington, Sonia R. Munoz, Donald M. Johnson, George Wardlow

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Transient smoke emissions pose potential hazards to human health and the environment. With the increased popularity of biodiesel, there is a need to determine if these fuels produce different levels of particulate matter in exhaust emissions. This study examined the transient smoke emissions of three fuels: No. 2 petroleum diesel fuel (D2, ASTM D 975), a blend of 20% biodiesel and 80% petroleum diesel (B20, ASTM 6751), and a 100% pure biodiesel derived from animal fats (B100, ASTM D 6751). Measurements of smoke emissions were taken using the SAE J1677 snap acceleration test procedure on a John Deere 3203 compact …
