abstract this study was performed in order to determine a suitable alternative substrate for peat in soilless culture in 2007. different plant wastes including carbonized rice hull, saw dust and dry pine leaves (pinus eldarica) were examined. treatments were 100% peat as control, peat plus dry pine leaves (1:1 v/v), peat plus carbonized rice hull (1:1 v/v) and peat plus saw dust (1:1 v/v). the ...

Institutional culture has become a buzzword in recent discussions of higher education in South Africa. Indeed, as references to it proliferate, there is a growing sense that institutional culture may well be the key to the successful transformation of higher education in South Africa. Or – to frame the matter as forcefully as do many recent analysts – it is simply the massive fact and bulk of i...

controlled environment may be adopted for a rapid multiplication of a large number of potato seed tubers. the controlled environment prevents seed tuber degeneration which may occur under field conditions. the objective of this study was to introduce new mini-tuber production system with high multiplication rate and low production cost. to evaluate the performance of culture systems in terms of...

Culture-as-situated-cognition (CSC) theory proposes that culture can be thought of at three levels. At the highest level, culture is a human universal, a “good enough” solution to universal needs. At the intermediate level, culture is a specific meaning-making framework, a “mindset” that influences what is attended to, which goals or mental procedure is salient. At the most proximal level, cult...

The goal of the TICK data management system is to make online publication of the fruits of research as easy as the publication of opinions on weblogs. In order to avoid the reinvention of many useful features, TICK leverages an existing content management system. This system already provides a framework for undergraduate research projects at Bard College. It is the authors’ position that the TI...

Henrich et al. address how culture leads to cognitive variability and recommend that researchers be critical about the samples they investigate. However, there are other sources of variability, such as individual strategies in reasoning and the content and context on which processes operate. Because strategy and content drive variability, those factors are of primary interest, while culture is ...

in this study, silver nanoparticles were synthesized  using the fungus, aspergillus fumigatus. the effects of three independent variables including glucose content of culture media, initial ph and initial spore concentration on biosynthesis of silver nanoparticles were investigated. these variables affect cell morphology, cell mass, size and morphology of silver nanoparticles and degree of silv...

The effects of non-saline soils with low, medium and high salinity, (EC = I, 7, 10 and 18 decisiemens per meter, respectively) on ion content and proline, were studied in different organs of  two colza (Brassica napus L.) cultivars, namely, PF 7045.91 and Hyola 401, in pot culture conditions and also the efficiency of comparing these changes were used as a tool for this study. Plants were grown...
