Methods for improving the basic kernel density estimator include variable locations, variable bandwidths (often called variable kernels) and variable weights. Currently these methods are implemented separately and via pilot estimation of variation functions derived from asymptotic considerations. In this paper, we propose a simple maximum likelihood procedure which allows (in its greatest gener...

this paper reviews recent strategies used for increasing specific yield and productivity in high cell density cultures. high cell density cultures offer an efficient means for the economical production of recombinant proteins. however, there are still some challenges associated with high cell density cultivation (hcdc) techniques. a variety of strategies in several aspects including host design...

microalgal growth curve, after the exponential phase, shows a stationary phase where algalbiomass production is inhibited and remains constant by some factors such as nutrientdepletion and intrinsic behavior. the present study is concerned with evaluating effects ofthe culture medium condition and intrinsic behavior on biomass production by dunaliellatertiolecta. to this end, effect of ph, nutr...

In this article three dimensional modeling of a planar solid oxide fuel cell (SOFC) was investigated. The main objective was to attain the optimized cell operation. SOFC operation simulation involves a large number of parameters,   complicated equations, (mostly partial differential equations), and a sophisticated simulation technique; hence, a finite element method (FEM) multiphysics approach ...

the microalgae, dunaliella salina was isolated from maharlu salt lake, south east of shiraz, iran. the isolated strain was identified by both morphological and physiological markers. the complete its region (its1 + its2) including the 5.8s rdna gene used as molecular marker confirmed our identification. growth and cell proliferation, total chlorophyll and carotenoid contents were determined in ...
