A major problems in the operation of laptop computers is overheating since it can affect the performance and stability, sometimes leading to system crash and hardware fatality. The objective of this work was to study the thermal behavior inside a laptop computer and to test the effectiveness of aproposed cooling method to overcome overheating problem. The proposed cooling system contained a the...
The orchid bee Euglossa imperialis sucks nectars through a slender proboscis. I tested how nectar properties influence this suction pressure and whether ambient air pressure sets the upper limit for suction feeding. Nectar intake rate was measured as a function of sucrose concentration (5-75% w/w), nectar viscosity (2-80 mPa s), and ambient pressure (101-40 kPa). Intake rate declines from about...
SEGES Pig Research Centre tested three different types of supplementary air inlets in a farrowing house to evaluate the effect on the sows’ immediate environment during the summer. The three different types included trough valves, a single ceiling inlet per sow and transverse ceiling inlets in the section. No supplementary air inlets were installed in the control section. The primary parameters...
BACKGROUND/AIM The objective of this study was to assess a hypothesized beneficial effect of fish consumption during the last trimester of pregnancy on adverse birth outcomes resulting from prenatal exposure to fine air particulate matter. METHODS The cohort consisted of 481 nonsmoking women with singleton pregnancies, of 18-35 years of age, who gave birth at term. All recruited women were as...
