We examined the association between community violence exposure and childhood asthma risk in a multilevel, multimethod, longitudinal study controlling for individual- and neighbourhood-level confounders and pathway variables. Analyses included 2,071 children aged 0-9 yrs at enrolment from the Project on Human Development in Chicago Neighborhoods. Multilevel logistic regression models estimated ...

Disparities in verbal ability, a major predictor of later life outcomes, have generated widespread debate, but few studies have been able to isolate neighborhood-level causes in a developmentally and ecologically appropriate way. This study presents longitudinal evidence from a large-scale study of >2,000 children ages 6-12 living in Chicago, along with their caretakers, who were followed where...

A study is made of the effects of superposed tangential force by off-axis indentation loading on curved bilayers consisting of brittle shells filled with polymer support material. Such loadings are pertinent to all-ceramic crown structures on tooth dentin in occlusal function. Layer flexure places the ceramic undersurfaces in tension, leading to fracture by initiation and propagation of radial ...

BACKGROUND American College of Cardiology/American Heart Association guidelines advise waiting 5 to 7 days before operating on P2Y12 inhibitor-treated acute coronary syndrome patients, to allow dissipation of its antiplatelet effects. Platelet transfusion is often used to restore hemostasis during operations, but its effectiveness and optimal timing are unclear. We investigated the degree of fu...

  Blackleg in cattle has been recognized since 1938 in Iran that mostly affects cattle in enzootic farm. Main object of this study was to prepare and formulate a concentrated potent vaccine for immunization of cattle against blackleg in Iran. Experimental concentrated blackleg vaccine was prepared according to the method described by FAO. The medium (Modified medium for production of experiment...

Active self-encapsulation (ASE) is a recently developed post-loading method based on absorption of (positively charged) proteins in microporous PLGA microspheres loaded with negatively charged polysaccharides (trapping agents). The aim this study was to investigate ASE for simultaneous loading and controlled release multiple growth factors. For purpose, vascular endothelial factor (VEGF), fibro...

AIM The purpose of this three-dimensional (3D) finite element study was to investigate orthodontic loading simulation on a single endosseous implant and its surrounding osseous structure, to analyze the resultant stresses and to identify the changes in the bone adjacent to the implant following orthodontic loading. MATERIALS AND METHODS Two models were constructed using finite element method ...

The force-coupling method (FCM) represents the dynamics of low Reynolds number suspension flows through a distributed, low-order, finite force-multipole expansion and provides an efficient, matrix-free method to solve the mobility problem for the particle motion. In concentrated suspensions, strong short-range lubrication forces are generated between particles in close proximity as fluid in the...

Method inlining is an optimisation that can be invalidated by later class loading. A program analysis based on the current loaded classes might determine that a method call has a unique target, but later class loading could add targets. If a compiler speculatively inlines methods based on current information, then it will have to undo the inlining when later classes invalidate the assumptions. ...
