r.ri ssue culture experiments designed to elucidate the affinity of the leprosy bacillus to nerve elements were fir st r eported in October 1958 (' . ). A preliminary note on continuous cultivation of an acid-fast microorgani sm isolated from lepromatous leprosy was published in the same year (' ). The present paper reports in vi fTo studies on the growth pattern of the organism, and also its b...

The economic value of irrigation water was determined through Contingency Valuation Method and Crop-Water Production function during wet and dry season of paddy cultivation. Factors namely, area under rice and water requirement influenced the willingness to pay for water by farmers. Social values of farmers’ over water were found to be high. The comparison of the economic value of water estimat...

The establishment and cultivation o ľ two human neoplastic cell lines is described. The cell line B-5GT was derived from bono giant cell tumor and B-6F8 from poorly differentiated fibrosarcoma. In comparison to the normal skin fibroblasts both cell lines have a potential for "indefinite" multiplication in vitro and 1 hoy exhibit growth properties which are asso­ ciated with malignant transforma...

Streptomyces citreus CBS 109.60 produced geosmin and a complex pattern of other volatile compounds during cultivation in a 2.5-liter laboratory bioreactor. Volatiles were isolated from disrupted cells, from the culture medium, and from the waste air of the bioreactor by adsorption on Lewatit OC 1064MD. Quantitative and qualitative analyses were carried out using capillary gas chromatography and...

Complex and distinct bacterial communities inhabit marine sponges and are believed to be essential to host survival, but our present-day inability to domesticate sponge symbionts in the laboratory hinders our access to the full metabolic breadth of these microbial consortia. We address bacterial cultivation bias in marine sponges using a procedure that enables direct comparison between cultivat...

2/ Professor of Ecology and Assistant Professor of Ecology. Departamento de Ecología. Universidad Autónoma. C-XV. Madrid (34) Spain. Abstract: Analysis of landscape preferences allows the detection of major dimensions as:(1) the opposition between "natural and humanized", (comprising features like vegetation cover, cultivation, pattern of landscape elements, artifacts, excavations, etc.); (2) a...

This paper reports a development of the microfluidic device for fabrication and cultivation of contractile skeletal muscle tissue in microchannels. Microfluidic processes were only used to develop contractile skeletal muscle microtissues in microchannels. Thus, the volume of the collagen gel used to fabricate the microtissues can be defined precisely. The fabricated microtissues can be cultured...

this research aimed at investigating the effect of different levels of nitrogen and planting patterns on dry matter production and growth physiological indices in intercropping maize and sunflower. to do this a split plot experiment carried out based randomized complete block design with three replications in research field of shushtar islamic azad university. the main plot included three level...

optimization of land allocation in golestan province for planting agricultural crops using compromise mathematical programming introduction: rational planning and optimization of agriculture are essential because of water and land constraints, the need to increase economic profit and to reduce the negative impacts of fertilizers and pesticides. to this end, decision-makers and planners need to ...

To investigate the characteristics of total factor productivity and its influencing factors in china’s soybean. Cobb-Douglas production function model is used in this study. The data is based on the period from 1990 to 2007, and C-D production function is applied twicely. The results of this study indicate that total factor productivity grows at 0.42% annually, the changes fluctuate apparently....
