A roadblock to the development of stand-alone microscale biomedical and chemical analysis systems is the relatively high heating power requirement of the microscale reactors, which typically exceeds the capability of low cost batteries. In this study, a microchannel thermal cycling reactor design using in-channel heating and passive cooling is proposed and a numerical model has been developed. ...

The experiment is aimed at knowing the effect of "body heating" on color preference. Eleven subjects with normal color vision served as subjects. Two tests, one of the "No Bath" and the other of the "Bath" were conducted. Hot bath immersion with 38.5 degrees C was performed for 30 min from 07:30 h to 08:00 h. Then, they were instructed to choose a single colored cloth out of 41 cloth colors (24...

The environmental concern, ensuring comfort for occupants, pushed us to search for the impact of glazed loggia on thermal comfort of adjacent space in Cons tantine climate, having s trong climatic cons traints. An experimental s tudy is undertaken and described in this paper. Analysis of the in situ results is also discussed. This work shows that in winter glazed loggia benefit largely from sol...

this paper presents a reduce roll vibration of the full vehicle model with passive suspension systems using vibration absorber to change the dynamic system matrix stat’s eigenvalue. since using the controller system has been splurged and required to energy consuming, in this research the vehicle body roll vibration has been reduced and supplied vehicle stability using a vibration absorber for t...

Passive methods to increase the heat flux on subcooled flow boiling are extremely needed modern cooling systems. Many methods, including treated surfaces and extended surfaces, have been investigated. Experimental research enhance using high sintered fiber attached surface was conducted. One bare (0 mm) four porous thickness (0.2, 0.5, 1.0, 2.0 were compared under three different mass fluxes (2...
