CULTIVATION CAPACITY OF A CULTIVATION FACILITY-INTEGRATED STRUCTURE BASED ON DISSOLVED OXYGEN BALANCE

Detection of airborne microbes in a composting facility by cultivation based and cultivation-independent methods.

Standard methods for quantification of airborne bacteria are based on cultivation and counting of grown colonies. From complex natural environments it is known that only a small fraction of the total number of cells can be cultivated on routinely used agar-media. Direct microscopic cell counting after DNA-staining usually generates higher concentrations of one to two magnitudes. The objective o...

Designing CSCW system for integrated, web-based, cotton cultivation services

Computer Supported Collaborative Work (CSCW) systems have attracted the attention of many software implementers on the area of multimedia applications, however very few of them have been used in agriculture. The necessity for using the CSCW environment in agriculture arises from the utilization and the rapid development of modern strategies of plant cultivation. In this paper we present the des...

Adaptive dissolved oxygen control based on dynamic structure neural network

Activated sludge wastewater treatment processes (WWTPs) are difficult to control because of their complexnonlinearbehavior. In thispaper, anadaptive controllerbasedonadynamic structureneuralnetwork (ACDSNN) is proposed to control the dissolved oxygen (DO) concentration in a wastewater treatment process (WWTP). The proposed ACDSNN incorporates a structure variable feedforward neural network (FNN...

Cultivation of Neisseria gonorrhoeae under low-oxygen conditions.

Sixteen Neisseria gonorrhoeae strains were examined for their abilities to grow under reduced oxygen tension. Low oxygen tensions were developed by evacuation-replacement procedures in which anaerobes and oxidation-reduction indicators were used as controls. All strains survived 96 h in a medium reduced to below -125 mV without visible growth. Detectable growth occurred at 0.05% oxygen, and 33%...
