At present the development together with an intensification of anaerobic processes calls for methods of observation and control. It is very important to know intermediate metabolites of anaerobic microorganisms and the activity of methanogenic ones. Presented analytical methods are GLC analyses of lower fatty acids, alcohols, aldehydes and ketones and components of biogas. The chromatography using steam as a mobile phase is also mentioned. The method of determining the fluorescent coenzyme F420 was tested and modified. This coenzyme is specific for methanogenic microorganisms and is closely linked with their activity. The determination of the total activity of the hydrogenase system of anaerobic microorganisms by means of the rate of the consumption and evolution of molecular hydrogen was also presented. The applicability and effectivenes of these methods were verified on natural samples. All the methods mentioned above give satisfactory results with available equipment, materials and techniques. 相似文献

Mostafa Baniasadi Mohammad Reza Zare' Mehrjordi Hossein Mehrabi Boshrabadi Hamid Reza Mirzaei Khalilabad Abbas Rezaei Estakhrooye 《Ground water》2020,58(4):560-570
In recent decades, increased extraction of groundwater for human and agriculture consumption has led to a substantial drop in groundwater level in large areas of across the world. Declining groundwater levels is a serious problem in itself and has multiple economic, social, cultural, political, security-related, and environmental externalities. The negative economic-environmental externalities of overextraction of groundwater in the Orzouiyeh plain in the Kerman Province, Iran, were evaluated using methods such as replacement cost, production function, market prices, shadow price, and the value of the input marginal product. After evaluating externalities, the Positive Mathematical Programming method was used to evaluate different water policies to reduce the consumption of groundwater. The total economic losses due to the externalities were calculated to equal 2.8 U.S. million dollars. The damages caused by environmental externalities were calculated to equal 436.1 U.S. million dollars. The results related to the positive planning model show that the best policy among different options, such as deficit irrigation policy or combined policies, involves implementation of pressurized irrigation systems. 相似文献

山西大同数字遥测地震台网记录的震相特征 总被引：1，自引：0，他引：1
从地球及地壳的分层结构出发，使用较成熟的理论，从地震波传播的基本原理入手，结合多年的震相观察分析工作实践，选取了山西大同数字遥测地震台网近年来的一些典型震相进行了分析，得出本台网记录到震中距小于100km的地方震震相有Pg，P11，Sg，S11震中距在100km～500km的近震震相有Pn，Pg，P11，Sn，Sg,S11对比分析了在本台网内及周边地区发生的爆破与天然地震在震相上的差异性，并对其特征作了较详细的描述。 相似文献
