The spinner flask bioreactor has been widely used in in vitro cell culturing processes due to its superiority in providing a homogeneous culture environment compared to traditional culturing methods. However, there is limited understanding of the flow fields in these bioreactors, and optimum culture conditions are yet to be determined. This article presents the experimental characterization of ...

The introduction of blade servers for diverse applications is expanding rapidly. The switch blade—a key network component of the blade server—must provide high performance to accommodate growing data-communication demands generated by network consolidation as in Fibre Channel over Ethernet (FCoE), have a compact, low-power-consumption design, and have switch control software optimized for blade...

Dans un article récent [1], Abderezak Ould Houcine montre qu’un groupe superstable résiduellement C pour une pseudo-variété C admet une série normale définissable G = G0⊲G1⊲· · ·⊲Gn telle que Gi/Gi+1 ∈ C pour i < n, et Gn est résoluble ; si G est ω-stable, on peut choisir Gn nilpotent. Nous étendons son résultat aux groupes supersimples, et montrons en même temps qu’on peut toujours prendre Gn ...

Introductions to Philosophy There are many good introductions to philosophy: [22], [53] and [1] have the advantage of being short and cheap. There are a few books [44, 11, 34] that introduce philosophical ideas by analysing films which raise philosophical issues. One of the advantages of these books is that they allow you to say that you are doing valuable research for this module while watchin...

The cause of crack initiation turbine blade had initially cracked by a fatigue mechanism over a period of time and then fractured by the overload at the last moment. Experimental procedure consists of macroscopic inspection, material verification, microscopic examination, and metallographic analysis and finally FE. And for these procedures, some specimens were prepared from a fractured blade. Us...

PURPOSE To compare the effects of different 23- and 25-gauge microincision vitrectomy trocar cannula entry systems on incision architecture. METHODS We tested one ridged microvitreoretinal (MVR), one non-ridged MVR, one pointed beveled, and one round-tipped beveled blade (n=10 per blade design per incision type). Each blade's straight and oblique incision architecture was assessed in a silico...

We present a model for buying agents in e-marketplaces to interpret evaluations of sellers provided by other buying agents, known as advisors. The interpretation of seller evaluations is complicated by the inherent subjectivity of each advisor, the possibility that advisors may deliberately provide misleading evaluations to deceive competitors and the dynamic nature of seller and advisor behavi...

Introduction PROPELLER [1] is a variant of multi-shot FSE technique, providing a high-resolution DWI with excellent immunity to offresonance. Its self-navigated nature around the center of K-space also allows for motion correction. The odd/even echo phase inconsistencies in the non-CPMG echo train were addressed using the “split-blade” method [2], where the blade width was reduced by a factor o...

To understand the effect of cavitation on tip leakage vortex (TLV), turbulent cavitating flows were numerically investigated using shear-stress transport (SST) k–ω turbulence model and Zwart–Gerber–Belamri model. In this work, two computations performed—one without other with cavitation—by changing inlet pressure pump. The results showed that had little difference between blade surfaces for a c...
