Rain-shelter cultivation is an effective cultural method to prevent rainfall damage during grape harvest and widely applied in the Chinese rainy regions. In this study we investigated the effect of rain-shelter cultivation on grape diseases and phenolic composition in the skins of Vitis vinifera cv. Cabernet Gernischet grape berries through the comparison with open-field cultivation at two vint...
used to make a beverage by the indigenous populations of the arealong before the first Spanish colonists arrived early in the sixteenth century. Jesuit priests who arrived in the middle of the century graduaUy took over control of IDost of the producing areas and began cultivation of selected varieties to ensure supply. Virtually aIl of Argentinian and Brazilian production is now cultivated, wh...
In the present study, we describe in vivo cultivation to produce oocysts. Seven-day-old mice were orally infected with 100,000-120,000 Cryptosporidium oocysts. On day 8 post-infection, the mice were killed by ether, and the small and large intestines collected. A simple extraction procedure was used and purified using Ficoll gradient centrifugation. After purification, the oocysts were preserve...
The organization of crop cultivation practices is still far from completion, and Web Resources are not used adequately. This paper proposed a method, based on SVM, to organize the knowledge of crop cultivation practices efficiently from Web Resources. The knowledge organization method of crop cultivation was proposed with Good Agricultural Practices (GAP) in the application of the crop cultivat...
-carotene has been used for years as natural food colorants and in cosmetics and healthcare due to their antioxidant property. The production of -carotene by Mucor azygosporus was evaluated, utilizing deproteinized waste whey filtrate. Since pigments are intracellular, their extraction needed after cell cultivation. In this study, different strategies for extraction of -carotene from M. azyg...
The objective of this research is to quantify the effects of liquid swine manure application on antibiotic and nutrient (N and P) losses via surface runoff and subsurface drainage under a conventional (moldboard plowing) and a conservation (chisel plowing) tillage system. The field experiment is set up at the University of Minnesota Southwest Research and Outreach Center, Lamberton, Minnesota. ...
To counteract rigidification by standardization, we need: (1) employees' self-generating experimentation without punishment for failures; (2) letting "the nail which sticks out" grow instead of hammering it down; (3) examining crazy ideas seriously; (4) cultivation craftsmen's pride filling the requirements like robots; (5) spontaneous change-generating quick interaction among heterogeneous emp...
BACKGROUND AIMS Spontaneous mutagenesis often leads to appearance of genetic changes in cells. Although human multipotent mesenchymal stromal cells (hMSC) are considered as genetically stable, there is a risk of genomic and structural chromosome instability and, therefore, side effects of cell therapy associated with long-term effects. In this study, the karyotype, genetic variability and clone...
There is a clear need for new approaches in the field of microbial community analyses, since the methods used can be severely biased. We have developed a DNA array-based method that targets 16S ribosomal DNA (rDNA), enabling the direct detection and quantification of microorganisms from complex communities without cultivation. The approach is based on the construction of specific probes from th...
