In this study, we report measurements of CFC12 (CCl2F2) in firn air and in air extracted from shallow ice cores from three Antarctic sites. The firn air data are consistent with the known atmospheric history of CFC-12. In contrast, some of the ice core samples collected near the firn-ice transition exhibit anomalously high CFC-12 levels. Together, the ice core and firn air data provide evidence...

Development which is less attention to the environment, inefficient use of energy as well as the increasingly dense city make space for the concept of green building to grow even more in Indonesia . The purpose of this study was to determine the extent to which the implementation of green building principles in commercial buildings. There are three buildings complexes that were examined in this...

The purpose of the present work is to work out an approach for the development of software and the choice of hardware structures when designing subsystems for automatic control of technological processes realized in living objects containing limited space (microenvironment). The subsystems for automatic control of the microenvironment (SACME) under development use the Devices for Air Prophylact...

In this paper we outline the fundamentals for a tactile feedback system to be used in conjunction with openair computer music performance devices. Some underlying physiological and perceptual mechanisms of haptics are examined, some currently available open-air controllers are reviewed, and previous technologies and experiments regarding haptic/tactile feedback are surveyed. Our VR/TX system is...

Carbon monoxide (CO) poisoning is the most common fatal poisoning in the United States. The circumstances often involve an unsuspected increase of CO in an enclosed environment. Victims often are unaware that their activity or environment placed them at risk for CO poisoning. The possibility of open air CO poisonings was first reported in 1987. We present a case of open air CO poisoning resulti...
