A single vacuum tube based solar cooker has high energy and exergy efficiency, and is capable of achieving cooking temperatures as high as 250 C. The reason for high energy and exergy efficiencies of this solar cooker is the high achievable concentration ratios of 15e20, which are not possible with multiple vacuum tube based solar cookers. In this paper, a comparative study has been carried out...

this paper develops an analysis of budget deficit financing in termsof a crowding out or crowding in effect on the activity of the privatesector for the economies of iran and algeria as two mena countries,(because of its economic structures (dependence on oil revenue)) duringthe period 1970-2012 by using cointegration and vector errorcorrection approaches. the analysis confirms the existence of...

Using various spectroscopic techniques such as UV-visible spectroscopy, circular dichroism spectroscopy, NMR spectroscopy, small-angle X-ray scattering, transient grating, and transient absorption techniques, we investigated how cell-mimetic environments made by crowding influence the photocycle of photoactive yellow protein (PYP) in terms of the molecular volume change and kinetics. Upon addit...

Emergency department (ED) crowding is a serious problem in most tertiary hospitals in Korea. Although several intervention models have been established to alleviate ED crowding, they are limited to a single hospital-based approach. This study was conducted to determine whether the new regional intervention model could alleviate ED crowding in a regional emergency medical center. This study was ...

We present a multiscale approach to model diffusion in a crowded environment and its effect on the reaction rates. Diffusion in biological systems is often modeled by a discrete space jump process in order to capture the inherent noise of biological systems, which becomes important in the low copy number regime. To model diffusion in the crowded cell environment efficiently, we compute the jump...

Oscillatory synchronization of neuronal populations has been proposed to play a role in perceptual integration and attentional processing. However, some conflicting evidence has been found with respect to its causal relevance for sensory processing, particularly when using flickering visual stimuli with the aim of driving oscillations. We tested psychophysically whether the relative phase of ga...
