Future energy systems and thus the climate are affected by many factors, such as energy resources, energy demand, energy policy and the choice of energy technologies. Energy systems of the future are facing three main challenges; the steady growth of global energy demand, the energy resource depletion, as well as the increasing emissions of carbon dioxide (CO 2) and other greenhouse gases and t...

Dynamic envelope/lighting systems have the potential to optimize the perimeter zone energy balance between daylight admission and solar heat gain rejection on a real-time basis, and to increase occupant comfort. Two side-by-side full-scale offices in Oakland, California were built to further develop and test this concept. An automated venetian blind was operated in synchronization with a dimmab...

Astronomical interest in observing phenomena within the terahertz frequency spectrum has driven demand for extremely sensitive heterodyne receivers. Traditionally, niobium-based SIS tunnel junctions are used by the radio astronomy community in such receivers for observations below 700GHz. Research on novel devices for heterodyne mixing aims to extend experimental capabilities of sensitive recei...

Heating, Ventilation, and Air Conditioning (HVAC) systems account for a significant portion of power consumption in commercial buildings all over the world [1, 4, 5, 6]. Since HVAC systems are designed for centralized cooling supplies, power consumption in each room is inestimable. Therefore, administrators are motivated to apportion the electricity payment for actual users. The even apportionm...

Renewable energy exploitation in the building sector can lead to significant savings and carbon dioxide emission avoidance. The objective of this study is detailed investigation a biomass-driven absorption heat pump for heating cooling. practically single-effect chiller operating with Lithium-bromide/water solution it has been properly modified production during winter. This system novel one it...

Blood anesthetic concentration and clinical indicators related to anesthetic management during surface-induced deep hypothermia were determined in seven adult mongrel dogs. The azeotrope of halothane and diethyl ether was assayed by gas chromatography. Blood concentration of halothane ranged from a pre-cooling control of 0.74 vol % to 0.11 vol % at 20 degrees C rewarming; ether ranged from 0.06...
