To evaluate the concept of metabolic cold adaptation in Antarctic fungi, we compared the activities of several key enzymes of the glycolytic pathway and the TCA cycle (hexokinase, glucose-6-phosphate dehydrogenase, glyceraldehyde-3-phosphate dehydrogenase, succinate dehydrogenase, isocitrate dehydrogenase, and malate dehydrogenase) in psychrotolerant Penicillium sp. 161 and mesophilic Aspergill...

An ultra scale-down primary recovery sequence was established for a platform E. coli Fab production process. It was used to evaluate the process robustness of various bioengineered strains. Centrifugal discharge in the initial dewatering stage was determined to be the major cause of cell breakage. The ability of cells to resist breakage was dependant on a combination of factors including host s...

In a comparative study, three di erent procedures of stabilisation techniques are considered for incompressible viscoelastic ow. The standard benchmark of ow past a sphere falling in a cylindrical vessel is employed to test these stabilisation techniques. First, discontinuity capturing (for stress) has been employed to investigate stabilisation properties. Then, the Zienkiewicz Zhu (ZPR-Q) quad...

Contractile actomyosin stress fibers are critical for maintaining the force balance between the interior of the cell and its environment. Consequently, the actin cytoskeleton undergoes dynamic mechanical loading. This results in spontaneous, stochastic, highly localized strain events, characterized by thinning and elongation within a discrete region of stress fiber. Previous work showed the LIM...

The course of a primary infection with Dipetalonema viteae was studied in one randomly bred and in one inbred strain of hamster. Worm recovery and the duration and intensity of the microfilaraemia were analyzed and related to the humoral immune response of the host by using the indirect immunofluorescent antibody test on frozen sections of female worms, on eggs and on intact microfilariae. The ...

In this study, the recovery of strain-hardening rate (RSHR) was discovered for the first time in polycrystalline materials (Ni-Si alloys) that have only dislocation activities during tensile test. Detailed microstructure characterizations show that the activation of dislocations in the secondary slip systems during tensile deformation is the major reason for this RSHR. By taking into account ot...

We determined the rates of survival of six clinical and two control strains of Neisseria gonorrhoeae in six commercial transport systems, using NCCLS standard M40-A methodology. Differences in strain recovery and system performance were marked. A strain less robust than the recommended ATCC 43069 would provide a more exacting standard.

conclusions pci was accompanied by some improvement in left atrial deformation indices as assessed by tissue doppler imaging. revascularization can, therefore, improve patient outcome. results regarding changes in left trial functional parameters after pci, those such as the strain of the septal wall and the anterior and inferior walls and the strain rate of the anterior and lateral walls signi...

The rheological properties of blends of immiscible homopolymers have received much attention in recent years (Tucker and Moldenaers 2002). Several publications have been devoted to examining the relationship between the rheology and morphology of two-phase blends. A key strategy employed by many researchers was to conduct experiments on ‘‘model’’ blends that were comprised of rheologically-simp...
