This paper describes an effort to develop timestepping methods for partial differential equations that can overcome the difficulties that existing methods have with stiffness of the system of ordinary differential equations that results from spatial discretization. Stiffness is caused by the contrasting behavior of coupled components of the solution, and makes “one-size-fits-all” polynomial and...

BACKGROUND AND PURPOSE Postoperative muscle strength and component alignment are important factors affecting functional results after total knee arthroplasty (TKA). We are not aware of any studies that have investigated the relationship between them. We therefore investigated whether coronal malalignment of the mechanical axis and/or of individual implant components would affect knee muscle str...

level of the hypothesis is referred to as an expectation-lank. The node at the end of an expectation-link is a model-based hypothesis element, and the link represents support from above (i e , the reason for proposing the hypothesis element is to be found at the higher level). 2. ,4 link which goes in the opposite direction, from lower levels of abstraction to higher, is referred to as a reduct...

Kurumsal sosyal sorumluluk (KSS) faaliyetlerinin firma riskini azaltması beklenmektedir. Çünkü KSS özsermaye ve borç maliyetini, bilgi asimetrisini azaltırken
 finansal performans itibarını artırdığı bilinmektedir. Bu çalışma, KSS’nin riski (toplam risk, sistematik risk olmayan risk) üzerindeki etkisini incelemektedir. Çalışmanın örneklemi, 2009-2020 yıllar arasında Borsa İstanbul’da faali...

To assess the efficacy in providing improved function and pain relief by administering 8 weeks of acupuncture as adjunctive therapy to standard care in elderly patients with OA of the knee. This randomized, controlled, blinded trial was conducted on 55 patients with OA of the knee. Forty-one patients completed the study (26 females, 15 males, mean age ± SD 71.7 ± 8.6 years). Patients were rando...

Sleepiness is a major risk factor for serious injury and death in accidents. Although it is important to develop countermeasures to sleepiness to reduce risks, it is equally important to determine the most effective timing for these countermeasures. To determine optimum timing for necessary countermeasures, we must be able to predict performance errors. This study examined the predictability of...

Purpose. Patellar resurfacing during prosthetic replacement of the knee is associated with loosening and the need for secondary revision. In many cases the patella is left unreplaced during this procedure in order to decrease the revision risk. Some of these patients remain symptomatic after knee replacement. Secondary isolated resurfacing of the previously unresurfaced patella in total knee ar...

OBJECTIVE To translate, culturally adapt and validate the "Knee Society Score"(KSS) for the Portuguese language and determine its measurement properties, reproducibility and validity. METHODS We analyzed 70 patients of both sexes, aged between 55 and 85 years, in a cross-sectional clinical trial, with diagnosis of primary osteoarthritis ,undergoing total knee arthroplasty surgery. We assessed...

This paper presents a cross-comparison of the data acquired by the MODIS and CloudSat sensors in order to understand the limit of the developed cloud-mask algorithm and to provide a quantitative validation assessment of cloud masks by using exclusively remotely sensed data. The analysis has been carried out by comparing both the intermediate levels of the cloud mask such as the brightness tempe...

A small artery model (SAM) for self-heated thermistor measurements of perfusion in the canine kidney is developed based on the anatomy of the cortex vasculature. In this model interlobular arteries and veins play a dominant role in the heat transfer due to blood flow. Effective thermal conductivity, kss, is calculated from steady state thermistor measurements of heat transfer in the kidney cort...
