Electrostatic adhesion technology has broad application prospects on wall climbing robots because of its unique characteristics compared with other types of adhesion technologies. A double tracked wall climbing robot based on electrostatic adhesion technology is presented including electrode panel design, mechanical structure design, power supply system design a...

Reducing mixing in both flat panel and tubular photobioreactors can result in a positive net energy balance with state-of-the-art technology and Dutch weather conditions. In the tubular photobioreactor, the net energy balance becomes positive at velocities < 0.3 ms-1, at which point the biomass production cost is 3.2 €/kg dry weight. In flat panel reactors, this point is at an air supply rate <...

Until 2012, most of China’s population lived in rural areas with markedly different patterns of household energy consumption from those in Chinese cities. The studies so far done on residential energy use in rural Chinese households have been limited to questionnaire surveys and panel data analyses. Hardly any studies on energy demand in rural areas have considered both the climatic and economi...

A 66-year-old woman with long-term essential hypertension presentedwith poorly controlled bloodpressure in spiteof six antihypertensive drugs. Percutaneous renal denervation was indicated as a treatment of resistant arterial hypertension. Renal angiography showed ‘strings of beads’ appearance characteristic of fibromuscular dysplasia (FMD) in the mid-segment of the right renal artery (Panel A)....

This paper examines the impact of the birth rate on economic growth by using a panel data set of 28 provinces in China over twenty years. Because China’s one-child policy applied only to the Han Chinese but not to minorities, this unique affirmative policy allows us to use the proportion of minorities in a province as an instrumental variable to identify the causal effect of the birth rate on e...

The corner fire characteristics with two inert walls are compared against those one or combustible through a set of standard Single Burning Item (SBI) tests. study examines how the behavior is affected by flame spread over walls. In case wall, side Calcium Silicate (CS) panel. As for different materials have been tested, namely, plywood and Medium-Density Fiberboard (MDF) panels. results indica...
