economies is of utmost importance. In the United States, corn is considered to be a cheap energy crop and is widely cultivated for ethanol production. In contrast to corn, switchgrass is an easily cultivated plant that can be used for lignocellulosic biomass and ethanol production. Switchgrass (Panicum virgatum L.) is a warm-season perennial grass. As a native to North America, this grass is thought to be significantly dominant in prairies throughout the country. Switchgrass thrives in regions…

in order between April and mid-June where the graph shows the lake had some of the highest biomass of Diatoms, Dinoflagellates, and Green algae. The independent variables would be the N and P in each experimental group and the amount added in each setting; other factors like light, temperature, predation, and competition will vary from month to month. The dependent variable would the phytoplankton biomass in each experimental group. The first experimental group would help give a ratio between…

By:Roman Adler. Did you know that bottled water can hold toxic chemicals, and it can make people sick? This is only one bad thing with bottled water. Bottled Water is not sustainable, though the people who make it told us it is. Waunakee should ban water bottles. There are many websites about bottled water being bad. According to Christiana Z. Peppard Ph.D. , Water bottles are not sustainable. In one week people throw away about 35 million empty water bottles. If it takes 450 years to…

used in lesser amounts to pull in sustainable energy the use of coal will still be a factor. In efforts to build our community with sustainable resource local government and officials are looking at two energy sources which would work in our area. Biomass which comes from plant materials and animal waste which is found on the outskirts of the community through our farmers. Then there is hydroelectric power which utilizes the movement of the nearby river to generate…

from cows and other ruminants can be strong and extremely unpleasant, however cow waste is a great source of energy that can be used to power the farm. The purpose of this science fair project is to discover what kinds of biomass are best for producing biogas. The kinds of biomass you will investigate are cow manure by itself and cow manure with vegetable peelings or with mashed banana. You will figure out how…

The total weeds biomass decreased significantly (P ≤ 0.01) in genetically diversified wheat plots compared with monocultures (Figure 3). The highest weeds biomass was observed in the monocultures of ERWYT 91-11 (M2) and Shiroodi (M1), 133 and 130 g m-2 respectively. Weeds biomass was the lowest, 76 g m-2, in Shiroodi: ERWYT 91-15 mixture (I2, Figure 3). This was a reduction of ~43 % and 41 % compared to monocultures of Shiroodi and ERWYT 91-15 respectively. The biomass of weeds grow in F2…

is the temperature of biomass fed to the gasifier and Ta is the temperature of air fed to gasifier. Solving the above equations simultaneously gives us the no. of moles of each of the gases in the pro-oxidation zone per mole of biomass and the temperature of the pyro-oxidation zone. The % of each of the components…

“Scale-dependent habitat use of Acadian Flycatcher (Empidonax virescens) in central Ohio” by Marja H. Bakermans and Amanda D. Rodewald, published in 2006, examines the selection of habitat across three spatial scales and the effects of understory arthropod biomass, vegetation structure and breeding productivity. As human populations grow and urban development increases desirable habitat for many habitat-specific species decreases resulting in population declines. It is important to understand…

condition makes their cultivation feasible, thus productivity is limited mostly by the available of light. Responses by algal cells to nutrients and cultivation environments can be used to manipulate the processes to favour the production of algal biomass. (Benemann, 2002). The conversion of light energy into chemical energy involves a two-step process known as the dark reaction and light reactions. Dark reaction is the process of carbon fixation reaction that can occur in the presence or…

elution that corresponds to the alpha-ketoglutarate will be separated from the rest of the biomass. Once the alpha-ketoglutarate is isolated, it can undergo an acid-base titration in order to determine its concentration. An auto-titration will be in order to get the most accurate midpoint. The necessary calculations and data analysis will be done to determine the final concentration present in the biomass. This can then be compared for all of the groups: the experimental ΔglgC cyanobacterial…
