Purpose: A theory states that strong core stability allows athletes to fully transfer forces from the upper extremities to lower extremities, and finally to the ground. On the contrary, weak core stability causes alterations in transferring forces, reduces sport performance, and increases risk for injury, especially in the lower extremities. Therefore, the current study investigated the relatio...

abstractbackgroundentity. it is hypothesized to result from abnormal patellar tracking caused by altered motorcontrol. deficit in neuromotor control of the core may be a remote contributing factor to thedevelopment of pfp. application of reliable emg measures would be helpful to handle thistheory. therefore, the purpose of this study was to determine the test-retest reliability of thecore and v...

hepatitis c virus (hcv) is an important agent causing chronic liver infection, which often leads to liver cirrhosis and lethal hepatocellular carcinoma (hcc). at present, there is no effective hcv vaccine for prevention of hepatic disease and the standard treatment is neither economical nor fully effective in all the patients. however, vaccination based on structural and nonstructural proteins ...

ArvandHerd is a sequential satisficing planner that uses a portfolio consisting of LAMA and Arvand. This planner won the multi-core track of the 2011 International Planning Competition. In this paper, we describe the various components of ArvandHerd, the updates made for the 2014 competition, and the modifications that allow ArvandHerd to compete in the single-core sequential satisficing tracks.

the number of constructed dams has been largely increased due to high demands of water supplies, and earth dams are the most common types since they are more compatible to the environment. nevertheless, the stability of these important structures during earthquakes has to be carefully evaluated and guaranteed. in the past, earth dams usually designed with pure clay core, but in recent decades t...

The central purpose of the research is to support the California Department of Transportation (Caltrans) Quieter Pavement Research Program, which has as its goals and objectives the identification of quieter, safer asphalt pavement surfaces. The research conforms with Federal Highway Administration (FHWA) guidance provided to state departments of transportation (DOTs) that conduct tire/pavement...

Objectives: The aim of this study was to compare the microtensile bond strengths (µ TBS) of three core materials with one lithium disilicate reinforced ceramic using two resin cements. Methods: Three core materials (Nulite F® (Biodental Technologies), Filtek Z250® (3M-ESPE), Prettau-Anterior® (Zirkonzhan, Germany)) were prepared as blocks (10×10×4 mm3) according...

introduction: in cases of severe hard tissue loss, 2 mm circumferential ferrule is difficult to achieve. so in these cases we should use different ferrule designs. this in vitro study investigated the effect of different ferrule designs on the fracture resistance of teeth restored with bonded post and cores. materials and methods: forty freshly-extracted central incisors were endodontically tre...
