the use of in vitro potato shoot cultures for protoplast isolation is desirable for consistent protoplast qualities. ethylene build-up in the culture vessels causes problems for leaf growth (e.g. decreasing leaf surface, dry weight and chlorophyll) in shoot culture. fifty to one hundred µm silver thiosulfate (sts) produced a larger leaf area as a source of plant material for protoplast isolatio...

Schwann cells are the glial cells of the peripheral nervous system (PNS) which both myelinate and provide trophic support for their associated axons. Their functions are critical for proper development, homeostasis, and regeneration of the PNS. Schwann cells can be isolated and expanded in culture. Such a culture can be used as a source of myelinating glia in culture or as a source of Schwann c...

After observing a contradiction between the 'official' ideology defined by open-source licenses and the actual behavior of hackers, we examine the actual customs which regulate the ownership and control of open-source software. We discover that they imply an underlying theory of property rights homologous to the Lockean theory of land tenure. We relate that to an analysis of the hacker culture ...

In order to study the olfactory discriminating ability of lacustrine sockeye salmon (Oncorhynchus nerka) and masu salmon (O. masou), the integrated olfactory nerve response to various freshwaters was recorded by electrophysiological techniques. In both species independent of sex and gonadal maturity, each freshwater caused a different olfactory response. Source and effluent waters of the cultur...

Introduction: Early diagnosis of bacteremia and its complications is the most important part of the care and management of the children. The utility of polymerase chain reaction (PCR) techniques has been shown to identify pathogens in less and more optimal time. The aim of our study was to evaluate the importance and prevalence of occult bacteremia using universal PCR of blood in 3-36 month chi...

The main purpose of translating Tang poems is to exchange ideas and culture. On the basis of the theory of adaptablity in culturral context and translation criticism, the thesis discusses how to make the target language adapt to the cultural context of the source language during the process of the translation of Tang poems. Specifically, the target language should adapt the source language, the...
