Rising greenhouse gas emissions are causing climate change, and the world’s focus has shifted to the need to reduce our reliance on fossil fuels. There has been a rise in the published literature on the utilization of crops for bioenergy production in Louisiana. however, very few scholarly documents have used Geographic Information systems (GIs) to map the distribution of potential bioenergy crops in Louisiana. This study seeks to fill the void by evaluating the potential of bioenergy crops in Louisiana for energy production using GIs. Given this objective, the agricultural census data for 1999, 2009, 2019, and 2020 obtained from the U.s. Department of Agriculture were used in the analysis. The quantities of various crops produced in the state were loaded into an attribute table and joined to a shapefile using ArcGIs software. The symbology tool’s graduated option was used to create five maps representing each of the bioenergy crops in Louisiana. The findings of the GIs analysis show that some of the parishes, such as Franklin produced the most bushels of corn (13,795,416), Iberia produced the most tons of sugarcane (1,697,980), East carroll produced the most bushels of soybean (8,237,991), Tensas harvested the most bales of cotton (80,898) and Avoyelles produced the most bushels of sorghum (630,694). The abundance and availability of crops as raw materials for energy production will translate into lower prices in terms of energy use, making bioenergy crops a promising alternative to fossil fuels. In addition, gasoline price data from 1993-2022 was obtained from U.s. Energy Information Administration. A regression model for the average annual gasoline price over the years was constructed. The results show that the average annual gasoline price variation with respect to years is statistically significant (p 0.05). This suggests that gasoline prices will generally rise despite a price drop over the years. The paper concludes by outlining policy recommendations in the

The main task of this article was to prepared of new pigment model in situ solar cells accordance to charge-transfer complexes of rhodamine c(Rhc) donor as dye laser gain media with iodine(σ-acceptor) and chloranilic acid, cLA(π-acceptor). The synthesis stoichiometry of these complexes were of 1∶2(donor∶acceptor) with general formulas [(Rhc)]I·I3 and [(Rhc)(cLA)2]. The discussed data of elemental analysis, conductivity measurements, FT-IR, Uv-vis spectroscopy and photometric titration data visualized the stoichiometry, formula and complexity of the complexes. The physicochemical and spectroscopic analyses obtained suggested that the electron transfer occurred through nitrogen atom in a tertiary amine —N(c2h5)2 of Rhc donor with acceptor. The synthesized solid complexes were under go to thermogravimetric analyses to investigate their thermal stability and decomposition steps. The molar conductance measurements revealed that Rhc complexes have an electrolytic statement. The thermal stability of rhodamine c complexes was enhanced in comparable with Rhc itself. The polymer membranes of poly-methyl methacrylate)(PMMA) combined with the Rhc charge(transfer complexes in chloroform solvent have been prepared and characterized by(infrared & electronic) spectroscopy and scanning electron microscopy(sEM) morphological examination. The photo-stability properties of the Rhc complexes have been investigated.

starting with observations that were first published in 1982. a series of additional findings led to the discovery of an important property of eel's in late G2/ mitosis. In addition to being the most sensitive to killing, cells in this age-interval were also shown to be the most sensitive to radiation-induced neoplastic transformation. In this work, c3h mouse cells, designated 10T1 / 2, were irradiated with fission-spectrum neutrons and assayed in vitro via the endpoint focus formation on a monolayer of normal cells. From these observations, a biophysical model was developed to explain the anomalous finding that the frequency of transformation by low doses was enhanced when the exposure was protracted. In contrast to transformation by X- and 7-rays where repair and kinetics during exposure play dominant roles, with radiations like reactor neutrons and a-particles repair has a minimal effect; only cell kinetics acts significantly to modify transformation due to protracted doses. In this report, the lack of responsiveness of mitotic cells to promotion by the phorbol ester 12-0-tetradecanoylphorbol-13-acetate is shown further to agree with the findings with fission-neutrons and the model that, at low dose rate, enhanced transformation is due principally to the progression of cells into the window of sensitivity. Implications of this model for lung cancer due to environmental radon are also discussed.

受人类活动,尤其是化石燃料燃烧的影响,钒在环境中的含量急剧增加,改变了其在自然环境中的地球化学过程.作为陆源钒最主要的汇,海洋中钒的地球化学研究远远落后于其他元素.文章利用南海北部涠洲岛海域澄黄滨珊瑚1984~2015年的地球化学指标(v/ca、δ^(18)O、δ^(13)c等),高分辨率地重建了表层海水钒含量的变化历史.研究发现:珊瑚v/ca比值与海表风存在密切联系,显示出可以记录热带气旋活动的巨大潜力;珊瑚v/ca比值可以对人为钒排放的影响进行较为精确地记录和识别,这为检验钒污染历史提供了可靠手段.综合南海北部气候资料和统计数据,文章重建了南海北部人类钒排放的历史,认为工业和交通运输业的发展变革是造成南海北部人类钒排放出现阶段性显著差异的主要原因;在去除人为排放的信号后,珊瑚v/ca比值可以有效示踪热带气旋活动,因此为重建前器测时期的热带气旋活动提供了新的指标.
