THE production of mannitol by bacterial fermentation has been extensively studied, since the organisms concerned are a source of trouble in the wine industry. Gayon and Dubourg [1901] showed that although glucose, sorbose, galactose, mannose, sucrose, maltose, lactose, raffinose and xylose are all fermented, laevulose alone yields mannitol. They found that arabinose and trehalose are not attack...
the feasibility of kaolinite used as a low-cost adsorbent for the removal of pb(ii), zn(ii) and cu(ii) from aqueous solutions was investigated. during the removal process, batch technique was used, and the effects of heavy metal concentration and contact time on adsorption efficiency at ph of 4.5, under a constant temperature of 20?1 ?c were studied. the experimental results were analyzed using...
the current study examined iranian undergraduate efl students’ willingness to communicate with regard to their vocabulary knowledge. in general, participants were somewhat willing to communicate in english. the total mean score of 730 university students’ perception of willing to communicate was 83.53 out of 135. results, regarding four parts of willingness to communicate, revealed that part...
some researches made in the field of agency problem issue, deal with the role of control systems regarding owners and managers. in this research the relationship between the two control mechanisms, namely the voluntary disclosure (external control mechanism) and outside directors (internal control mechanism), which are reductive of agency problems, has been studied. for this reason, a sample ...
abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
Exact inference for Boltzmann machines is computationally expensive. One approach to improving tractability is to approximate the gradient algorithm. We describe a new way of doing this which is based on Bahadur's representation of the multivariate binary distribution (Bahadur, 1961). We compare the approach, for networks with no unobserved variable, to the \mean eld" approximation of Peterson ...

Removal of cesium from synthetic aqueous solution through adsorption on vermiculite, under batch equilibrium experimental condition at six initial values of pH (3, 4, 6, 9, 11 and 12) and five temperatures (25, 50, 75, 85 and 95 °C) has been investigated. It is necessary to propose a suitable model for a better understanding of the mecha...
