The lithium bromide chillers supplied from solar collectors are used to provide proper environmental conditions into industrial and civil buildings. To maintain the appropriate values for the temperature into the chiller's boiler, a control unit is introduced to avoid crystallization of the absorbent. The liquid flow process of the absorbent within the pipes of the chiller is a non-linear proce...

A low-cost and portable vector network analyzer (VNA) which covered operating frequency between 1MHz to 3GHz is used for vector reflection coefficient and standing wave ratio (swr) of the various microstrip antennas. This paper presents measurements of various ultra wideband (uwb) microstrip antennas for applications in biomedical field. Selection of antenna is an important key for detection of...

Equations for the calculation of VO2, VCO2, and evaporative water loss were derived for use of a paramagnetic gas analyzer with a flow-through respirometry system and an open or closed mask. The magnitude of errors involved in the determination of VO2 with no CO2 absorbent are small (+/-3%) but may be greater if no H2O absorbent is used, unless an appropriate correction is made for evaporative ...

ALL modern volatile anesthetics produce carbon monoxide in strongly exothermic reactions with anhydrous carbon dioxide absorbents. Although desflurane produces the most carbon monoxide, the reaction with sevoflurane produces the most heat. Using real anesthesia machines, sevoflurane, and desiccated Baralyme® (Allied Healthcare Products, Inc., St. Louis, MO), peak absorbent canister temperatures...
