Micromixer is a significant component of microfluidics particularly in lab-on-chip applications so that there has been a growing need for design and fabrication of micromixers with a shorter length and higher efficiency. Despite most of the passive micromixers that suffer from long mixing path and complicated geometry to increase the efficiency, our novel design suggests a highly efficient micr...

Introduction: Previous studies have shown that sesame oil affects memory and learning. In the present work, effect of a diet containing 10% sesame oil used during pregnancy was evaluated on short-term passive avoidance learning of offspring rats by Shuttle box. Methods: Female Wistar rats were divided into 2 groups (n = 9 each group). Control group consumed regular diet during pregnancy and...

Work-related musculoskeletal disorders are a major concern in the construction industry. The back is most commonly affected body part, accounting for about 43% of cases. To reduce loading, exoskeletons has been introduced workplace. Back-support potential interventions to physical demands on back. Successful application exoskeleton will require an assessment user acceptance and comfort with dev...

oil production optimization is one of the main targets of reservoir management. smart well technology gives the ability of real time oil production optimization. although this technology has many advantages; optimum adjustment or sizing of corresponding valves is still an issue to be solved. in this research, optimum port sizing of inflow control devices (icds) which are passive control valves ...

STUDY OBJECTIVE The aim was to estimate the quantitative impact of working conditions on cardiovascular diseases in Denmark. DESIGN The study was based on a review of recent epidemiological research publications in which relative risks were estimated and risk factor prevalences were determined. The impact of working conditions was quantified by means of aetiological fractions. SETTING The a...

A mathematical model was analyzed to obtain a quantitative and testable representation of the long-standing hypothesis that the respiratory muscles drive the chest wall along the trajectory for which the work of breathing is minimal. The respiratory system was modeled as a linear elastic system that can be expanded either by pressure applied at the airway opening (passive inflation) or by activ...
