Abstract A coupled model system, consisting of a distributed hydrological model and an economic optimization model, is applied 1) to investigate regional interdependencies between irrigated agriculture and regional water balance and 2) to identify optimized cultivation strategies. The coupled model system is applied to a case study for the semi-arid Atankwidi catchment in West Africa. The hydro...

We developed and tested a high-pressure optical chamber system for cultivation and microscopic observation of deep-sea organisms. The system is composed of an optical chamber, a highpressure pump, a pressure sensor and a microscope. The chamber has an observation cavity, 2 cultivation cavities and 2 sapphire windows. The pump is employed for perfusion of culture medium and for increasing the pr...

In the process of the cultivation of graduate students based on the tutor system, there need to be further studied on how to build the science and fair evaluation mechanism for ensuring and improving the cultivation quality of graduate students. On the basis of research on tutor system, the paper summarizes the evaluation principles of the development of point of view, vertical comparison of th...

Monocytes and macrophages, collectively termed the mononuclear phagocyte system, are intimately involved in a variety of physiological and pathological events (1-5). They participate in the inflammatory process, secrete numerous biologically active products, and are recognized as major effectors of immunity against neoplastic disease and infectious agents. Our present understanding of the physi...

in recent years, in order to enhance the health of agroecosystems, concerns on ecological inputs especially to produce medicinal plants, has been increased. in order to evaluate the effects of winter cover crops on pgprs activities and soil nitrogen content in simultaneous application of organic manures and biological fertilizer in a low input production system of cucurbita pepo under minimum t...

Miniaturization and parallelization of cell culture procedures are in focus of research in order to develop test platforms with low material consumption and increased standardization for toxicity and drug screenings. The cultivation in hanging drops (HDs) is a convenient and versatile tool for biological applications and represents an interesting model system for the screening applications due ...

the purpose of this correlational research was to investigate the factors influencing satisfaction whith sprinkler irrigation systems (sis) as perceived by the adopting farmers. the research instrument was a structural questionnaire with close-ended questions, the validity and reliability of which were confirmed. the target population included all the adopting farmers who cultivated and harvest...

Nannochloropsis salina was grown on a mixture of standard growth media and pre-gasified industrial process water representing effluent from a local biogas plant. The study aimed to investigate the effects of enriched growth media and cultivation time on nutritional composition of Nannochloropsis salina biomass, with a focus on eicosapentaenoic acid (EPA). Variations in fatty acid composition, l...

In this paper, a recommender system based on rough mereology was presented for predicting best cultivation dates for wheat in Egyptian Sinai Peninsula according to the required mean temperature for germination stage during October to December. The weather data was hourly collected from El-Arish weather station in north Sinai government from 1985 to 2013. As far as we know, this was the rst stud...
