identification microscopic fungi mycotoxins
2010/12/22
Contamination by microscopic fungi and mycotoxins in high moisture corn (HMC) silages conserved by chemical additives was investigated. The samples were examined for the concentration and identificati...
玉米秸秆等离子体热裂解液化实验（Experiment on Plasma Pyrolysis of Corn Stalk for Liquid Fuel）
生物质 玉米秸秆 热裂解 等离子体
2009/9/11
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...

Corn seedling weeds texture support vector machine recognize
2010/9/10
This study investigated the effect of a new approach, the support vector machine, as a classifier tool to identify the weeds in corn fields at early growth stage. Image segmentation was done by transf...
选取郑单958、辽单565、京科25玉米品种作为研究对象，从玉米籽粒的数字图像中提取与玉米籽粒的颜色、形状、尺寸等有关的6个形态结构参数，利用支持向量机(SVM)算法进行训练识别，同时与BP人工神经网络(NN)方法进行比较，结果表明，SVM算法识别效率较高，达到92.3%。
Corn-stalk lodging and borer damage as influenced by varying corn densitiesand planting geometry with soybean (Glycine max. L. Merrill)
stalk lodging borer damage planting densities planting geometry soybean
2008/11/26
Cultural practices which increase the amount of insect pressure can also increase the amount of lodging that occurs in the corn crop. Studies were therefore carried out, in the late cropping seasons ...
Comparison between apparent viscosity related to irradiation dose for corn starch and black pepper
irradiation viscometry dose-effect starch pepper
2008/11/21
Dose-effect relationship was studied in the rheoviscometric behaviour of geliffied suspensions of irradiated corn starch and black pepper, as the variation of the apparent viscosity and the shear stre...
Estimation of some chosen physical properties of extrudates obtained from corn semolina and oat bran mixtures
extrusion-cookin physical properties oat bran extrudate
2008/11/19
Some chosen properties of the extrudates obtained from corn semolina and oat bran were studied. Two component mixtures were extruded using a single screw extrusion-cooker S-45. The purpose of the rese...
