Campylobacter jejuni is one of the most common food-borne pathogens and chickens are the main source of these bacteria. Enterococcus faecium AL41, enterocin M-producing strain (deponed to the Czech C...
Many studies related to the multifunctionality of agriculture and rural areas have been conducted in both the natural and social sciences. One of the research topics dealt with in agricultural economi...
采用可视化单液滴反应器观察硫酸黑液在400~800℃范围内的热解膨胀行为,判断较低和较高温度下的不同膨胀特性。测定了3种硫酸盐黑液在450~850℃范围内热解永久性气体中H2、CO、CO2和CH4相对含量,考察热解气体中大量H2的主要来源。热解导致的总硫释放量通过对热解焦的分析得到,并用碘量法确定了气相中H2S含量。结果表明:高于500℃时,黑液膨胀至最大体积后将开始收缩,而低于此温度则膨胀至最大...
采用山东理工大学自制小型流化床设备,利用玉米秸秆为原料进行了热裂解过程及生物油特性的实验研究。结果表明采用等离子体加热,整个反应器的预热时间大约为1.5h,且反应过程中流化床内温度稳定,有利于生物质快速热裂解反应的进行。对反应产物——生物油热值特性作了分析,得出未经任何处理的生物原油的热值为18066.62kJ/kg,脱炭后热值低于脱炭前的生物油热值,其差值为3446.71kJ/kg,说明生物油中...
Picking a model for a problem is a major undertaking. If the model fits well then it can be used to increase understanding of the problem and/or for prediction. Several statistical procedures have bee...
Changes of dehydrogenase activity in Orthic Luvisol developed from loess (Ap horizon) under different aeration conditions were observed in a greenhouse pot experiment with barley Hordeum vulgare L. c...
A greenhouse experiment to test the relationship between the oxygen status of soil and the macroelement content was conducted. N-NH4+, N-NO3-, P and K content in the soil under oxygen stress conditio...
Dehydrogenase activity of an Orthic Luvisol developed from loess (Ap horizon) was observed in a greenhouse pot experiment with triticale cv. Jago vegetation under different aeration conditions. Soil ...
