the presence of particles in liquid-solid fluidized beds enhances the bed heat transfer, because the movement of the particles leads to an increased turbulence in the system. moreover, the violent movement of the particles has a positive effect on fouling of the heat transfer surface. the aim of this investigation was to perform systematic measurements of bed voidage and heat transfer coefficie...

Three basal plant tissue culture media, namely, N6, MS, and modified Y3, were compared to optimize micropropagation protocol for E. guineensis. Full strength media were used separately to regenerate plantlets directly using immature zygotic embryos (IZEs), and through somatic embryogenesis of calli obtained from IZEs. The plantlets regenerated by direct regeneration on three media were examined...

This paper uses critical realism to reflect upon the issue of theory in Marx‟s Labour Theory of Value (LTV). Like any theory, the LTV is rooted in a mode of theorisation. Rooting the LTV in an inappropriate (deductivist) mode of theorisation encourages the formulation of (quantitative) versions of the LTV that (a) have severe problems and (b) lack explanatory power. Conversely, rooting the LTV ...

Grape (Vitisvinifera L.) is one of the important fruit crop. Zinc is a micronutrient which plays important role in various metabolic processes in plants. Zinc works as auxin precursor in plants. The effect of zinc application to mothervine of Dog Ridge rootstock was studied in the present experiment. Zinc was applied in concentration of 0, 5.0, 10.0, 15.0 and 20.0 g/ mothervine and its effects ...

Optimal conditions for in vitro multiplication and rooting of cv. Willamette were investigated. High level of proliferation and multiplication after 90 days of culture on Murashige and Skoog (MS) medium with 100 mg·l myo-inositol, 2 mg·l thiamineHCl, 1 mg·l piridoxine-HCl, 1 mg·l nicotinic acid and 30 g·l sucrose and 8 g·l agar was considered together with two concentrations of BA (0,2 and 2 mg...

Word Sense Disambiguation (WSD) is the process of selecting a sense of an ambiguous word in a given context from a set of predefined senses. Sense Inventory usually comes from a dictionary or thesaurus. In Arabic, the main cause of word ambiguity is the lack of diacritics of the most digital documents so the same word can occurs with different senses. In this paper, we use the rooting algorithm...

OBJECTIVE To share four Canadian cities' experiences with bed bug infestations and to explore public health roles in managing them. METHODS We summarize presentations from a workshop at the 2010 Canadian Public Health Association Conference which examined the re-emergence of bed bugs in Canada and compared management approaches of municipal and public health authorities in four large Canadian...
