Sheet metal forming problems are typical in nature since they involve geometry, boundary and material non-linearity. Cup drawings involves many parameters like punch and die radius, clearance, lubrication, blank holding force and its trajectories etc. So designing the tools for cup drawing involves a lot of trial and error procedure. To reduce number of costly trial error steps, the process can...

The task force of the Korean Society for Reproductive Immunology recommends intravenous immunoglobulin G treatment in women with reproductive failure, including recurrent pregnancy loss and/or repeated implantation failure, who show cellular immune factors such as abnormal natural killer cell levels, natural killer cell cytotoxicity, and/or type 1 T helper immunity.

It is becoming clear that upregulated protein kinase C (PKC) signaling plays a role in reduced ventricular myofilament contractility observed in congestive heart failure. However, data are scant regarding which PKC isozymes are involved. There is evidence that PKC-alpha may be of particular importance. Here, we examined PKC-alpha quantity, activity, and signaling to myofilaments in chronically ...

results one-, three-, five-, and ten-year graft survival was 93.8%, 86.8%, 76.6%, and 37.4%, respectively. the results of the joint model showed that risk indicators, such as serum creatinine level (p < 0.0001, hr = 1.82), patient’s age (p = 0.006, hr = 1.03), and anti-thymocytes globulin (p = 0.019, hr = 2.57) had a significant relationship to graft survival. conclusions in general, our study ...

Maluf, Katrina S., and Roger M. Enoka. Task failure during fatiguing contractions performed by humans. J Appl Physiol 99: 389–396, 2005; doi:10.1152/japplphysiol.00207.2005.—By comparing the physiological adjustments that occur when two similar fatiguing contractions are performed to failure, it is possible to identify mechanisms that limit the duration of the more difficult task. This approach...

We introduce R-PFA, a new model for predicting whether or not a student will answer an item correctly based on the student’s history of practice. The key idea in R-PFA is to represent history as a recentcy-weighted proportion of correct responses. In an evaluation on a dataset from the Assistments tutoring system, we find that R-PFA improves predictive accuracy over other logistic regression mo...

BACKGROUND There have been few scientific studies that have examined usage of human growth hormone to accelerate recovery from injury. The hypothesis of this study was that human growth hormone would accelerate tendon-to-bone healing compared with control animals treated with placebo in a rat model of acute rotator cuff injury repair. METHODS Seventy-two rats underwent repair of acute rotator...

We fabricated a novel in-line conductive atomic force microscopy (C-AFM), which can analyze the resistive failures and examine process variance with an exact-positioning capability across the whole wafer scale in in-line DRAM fabrication process. Using this in-line C-AFM, we introduced a new, non-destructive diagnosis for resistive failure in mobile DRAM structures. Specially, we focused on the...

Few topics are more important to health than community development. At first, this assertion seems a wild exaggeration when considered in relation to other important contributors to health, such as high-quality medical care, healthy behavior, and good genetic stock. However, substantial evidence reveals that environmental and community forces also are important determinants of health. This obse...
