During the last 40 years studies in the mouse, including the production of chimeras, development of pronuclear injection techniques and the establishment of embryonic stem (ES) cells have provided models for the study of development and differentiation, precise and routes for genetic modification of the nuclear genome. The use of ES cells combined with homologous recombination allowed precise g...

The discovery and removal of logic design errors early In the development cycle Is critical to timely availability of market-driven processor products. This paper describes the part played by sirnulation in the Verification of the high-end models of the iBM Enterprise System/9000" (ES/900OW) processor family, and how that effort advanced the state of the art of logic design simulation. The incr...

Retinal ganglion cell (RGC) transplantation is a promising strategy to restore visual function resulting from irreversible RGC degeneration occurring in glaucoma or inherited optic neuropathies. We previously demonstrated FGF2 induced differentiation of mouse embryonic stem cells (ESC) to RGC lineage, capable of retinal ganglion cell layer (GCL) integration upon transplantation. Here, we evalua...

Considering the nite-volume solution of multi-dimensional multi-species reactive ows with complex chemistry, we concentrate on the numerical treatment of the chemical source terms in a fractional step approach. For two air-hydrogen chemistry models, we compare the numerical eeciency of linearized or totally implicit schemes, in both temperature-mass-fractions coupled and uncoupled formulations;...

processing of round potatoes (solanum tuberosum (l.) into chips in tanzania and particularlydar es salaam city is a growing business that attract low wages employees and unemployed occupants. proliferationof chips vendors with low knowledge, poor attitude and practice towards environment have resulted into poormanagement of potato peels waste which are haphazardly disposed of thus causing unhea...

Zusammenfassung Der Artikel stellt die Empfehlungen des Wissenschaftsrates zur Transformation wissenschaftlichen Publizierens zu Open Access vor und versucht Kernpunkte herauszuarbeiten. Anhand dieser Punkte wird erläutert, warum mit diesen deutlich wird, dass auch knapp 20 Jahre nach Unterzeichnung der Berliner Erklärung noch keine echte stattgefunden hat den mannigfaltigen Anstrengungen auf b...

strongyloidiasis, caused by a nematode parasite so-called strongyloides stercoralis is one of the major human intestinal nematode infections. considering that stool examination for strongyloides larvae is not a sensitive method and immunodiagnostic methods are more applicable for this purpose, so the present study was conducted to compare the somatic (s) and excretory - secretory (es) antigens ...
