This study investigates the relationship between economic conditions and health. Previous studies have estimated that they have a significantly negative correlation. However, there is a concern that mortality rates are non-stationary series, with which a chance of spurious correlation exhibits. By taking first difference on regressors and conducting unit-root tests for panel data, it shows some...

This study is to develop a micromachining technology for a light guidepanel(LGP) mold, whereby micro dot patterns are formed on a LGP surface by a singleinjection process instead of existing screen printing processes. The micro powder blastingtechnique is applied to form micro dot patterns on the LGP mold surface. The optimalconditions for masking, laminating, exposure, and developing processes...

In this paper, a theoretical model of a micro-perforated panel (MPP) backed by a finite cavity and flush-mounted in an infinite baffle is developed and its performance in terms of sound absorption is analyzed. The model allows an oblique incidence sound impinging upon the MPP absorber. The simplified Rayleigh integral method, thin plate theory and the acoustical impedance of the MPP are used to...

Today, Flapping Micro Aerial Vehicles (MAV) are used in many different applications. Reynolds Number for this kind of aerial vehicle is about 104 ~ 105 which shows dominancy of inertial effects in comparison of viscous effects in flow field except adjacent of the solid boundaries. Due to periodic flapping stroke, fluid flow is unsteady. In addition, these creatures have some complexities in kin...

because of its kinetic nature and computational advantages, the lattice boltzmann method (lbm) has been well accepted as a useful tool to simulate micro-scale flows. the slip boundary model plays a crucial role in the accuracy of solutions for micro-channel flow simulations. the most used slip boundary condition is the maxwell slip model. the results of maxwell slip model are affected by the ac...

We use longitudinal panel data from the EU-SILC for period 2005–2011 to examine micro and macro determinants, persistence dynamics of over-education. The key contribution in terms determinants over-education is inclusion macro-level explanatory variables control both aggregate supply demand labor market conditions. Their effects are found be strongly significant have expected sign. article also...

In current times, noise pollution is especially apparent in urban areas due to rapid development transportation, industrialization, and urbanization. The worsening detrimental human health behaviour as it can contribute disorders psychological disturbance. Thus, regulation crucial must be addressed with immediate effect. Micro-perforated panels (MPP) a potential solution mitigate on commercial ...
