Making cloud services responsive is critical to providing a compelling user experience. Many largescale sites, including LinkedIn, Digg and Facebook, address this need by deploying pools of servers that operate purely on in-memory state. Unfortunately, current technologies for partitioning requests across these inmemory server pools, such as network load balancers, lead to a frustrating program...

A high performance clarification system has been discussed for advanced aqueous reprocessing of FBR spent fuel. Dissolver residue gives the cause of troubles on the plant operation of reprocessing. In this study, the new clarification system based on the hybrid of centrifuge and filtration was proposed to get the high separation ability of the component of whole insoluble sludge. The clarificat...

Measurement of drainage relative permeability by the centrifuge method was first introduced by Hagoort. It has been shown that capillary end effects can cause errors in the measurements if a minimum rotational speed is not honored. To determine the min ! , we propose maintaining the value of capillary-gravity number, cg N , to be of the order of 10 -2 or smaller, at which the capillary end effe...

L'érythème annulaire centrifuge n'a souvent pas de cause connue, mais on découvre parfois une cause médicamenteuse (aspirine, vaccin), infectieuse (infection streptococcique, tuberculose, mononucléose infectieuse, trypanosomiase, grippe), une dermatose chronique (pemphigus, lupus érythémateux subaigu) ou une atteinte cancéreuse distante des lésions (cancer du poumon, de la prostate, de l'utérus...

Might the gravity levels found on other planets and on the moon be sufficient to provide an adequate perception of upright for astronauts? Can the amount of gravity required be predicted from the physiological threshold for linear acceleration? The perception of upright is determined not only by gravity but also visual information when available and assumptions about the orientation of the body...

A numerical model was developed to simulate the response of two instrumented, centrifuge model tests on soft clay and to investigate the factors that affect the seismic ground response. The centrifuge tests simulated the behavior of a rectangular building on 30 m uniform and layered soft soils. Each test model was subjected to several earthquakelike shaking events at a centrifugal acceleration ...

Centrifuge modeling has been considered as an effective means of studying flexural soil–pile interaction, yet the conventional use elastic material to model RC pile prototype is unable reproduce important nonlinear quasi-brittle behavior. It also remains a challenge numerically interaction due nonlinearity both soil and materials. This paper presents small-scale for testing soil–structure under...

The centrifuge force microscope (CFM) was recently introduced as a platform for massively parallel single-molecule manipulation and analysis. Here we developed a low-cost and self-contained CFM module that works directly within a commercial centrifuge, greatly improving accessibility and ease of use. Our instrument incorporates research grade video microscopy, a power source, a computer, and wi...

Numerous sucrose gradients can be prepared simultaneously by diffusion in horizontal centrifuge tubes.

Reports on infectious diseases acquired by bacteriological laboratory staff from their work emphasize the risk of contracting tuberculosis by handling tuberculous specimens. Recent advances in the chemotherapy of tuberculosis have greatly increased the amount of bacteriology done in routine hospital laboratories, primary culture and then sensitivity tests being required where previously a direc...
