in the course of this study, empirical models were developed for the pressure-density relationship in a large cubic baler for baling alfalfa and barley straw. least squares regression analysis was employed to develop the empirical model and estimate the model coefficients by minimizing the summation of the squared differences between data resulting from the developed empirical model and the cor...

reactive powder concrete (rpc) is an ultra high performance concrete which has superior mechanical and physical properties. the rpc is composed of cement and very fine powders such as crushed quartz (100–600 μm) and silica fume with very low water/binder ratio (w/b) (less than 0.20) and super plasticizer (sp). the rpc has a very high compressive and tensile strength with better durability prope...

We studied the effect of two social settings (collaborative versus competitive) on the visual and auditory expressions of uncertainty by children in two age groups (8 and 11). We conducted an experiment in which children played a quiz game in pairs. They either had to collaborate or compete with each other. We found that the Feeling-of-Knowing of eight-year-old children did not seem to be affec...

The use of negative pressure wound therapy (NPWT) is increasing in both the inpatient and outpatient settings. We conducted a systematic review on the efficacy and safety of NPWT for the treatment of chronic wounds in the home setting. We searched MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and the Cumulative Index to Nursing and Allied Health Literature, up to June 201...

BACKGROUND Child screen viewing (SV) is positively associated with poor health indicators. Interventions addressing rule-based parenting practices may offer an effective means of limiting SV. This study examined associations between rule-based parenting practices (limit and collaborative rule setting) and SV in 6-8-year old children. METHODS An online survey of 735 mothers in 2011 assessed: t...
