BACKGROUND The development of soft tissue cervicofacial emphysema after dental treatment is a rare complication, with few descriptions in the dermatologic literature. It is usually restricted to only moderate local swelling. However, spread of larger amounts of air into deeper spaces may sometimes cause serious complications, including airway compromise due to accumulation of air in the retroph...

introduction recently, the presence of residents and their behavior in the urban space have become so important that manycontemporary urban theorists view the presentera as the “turn of urban space and what is happening in it”. the importance of urban behaviors and activities could be discussed from different points of view. in the contemporary literature of urban design, the mutual interaction...

BACKGROUND Air embolism can occur in a number of medical-surgical situations. Venous air embolism is frequently lethal when a substantial amount enters the venous circulation rapidly and can lead to significant morbidity if crossover to the systemic arterial circulation occurs. The diagnosis of massive air embolism is usually made on clinical grounds by the development of abrupt hemodynamic com...

in this research, the selective oxidation of benzene to maleic anhydride (man) in a fixed-bed reactor was studied. the gas phase catalytic oxidation of benzene was carried outin a laboratory scale fixed bed reactor on the catalysts, which were prepared having two different compositions on silica gel. the effects of temperature, flow rates of benzene and air, and catalyst type on the reaction se...

Traditionally, attic space in buildings is perceived as a source of nuisance where the moisture condensation occurs in winter encourages mildew growth, and heat build up in the attic space in summer increases the cooling load. However, if the attic is integrated in a holistic design and control strategy, it can function as a solar collector, a heat exchanger, and a desiccant!. This research inv...

In recent years, the research and development of energy-saving control in air-condition system has become a hot spot with the advance of science and technology. In this paper, we proposed a fuzzy control mechanism for air-condition system, which combines the fuzzy control and multi-point sensing technology. When people feel cooler or hotter indoor, the air condition should promptly detect the t...

In this study, a Fuzzy Logic Controller was designed to provide the conditions necessary for operating room. For this purpose, real operating rooms have been studied to see if there are more useful, reliable & comfortable ones. How an operating room can be controlled with FLC & its advantages & disadvantages have also been researched. In this system heat, particle humidity & oxygen are used as ...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014205463 DESCRIPTION An 11-month-old male child with Down syndrome was admitted to the pediatric intensive care unit (PICU) after an uncomplicated correction of his complete atrioventricular septal defect. On postoperative day 5, there was an acute incident after...

in a fuzzy metric space (x;m; *), where * is a continuous t-norm,a locally fuzzy contraction mapping is de ned. it is proved that any locally fuzzy contraction mapping is a global fuzzy contractive. also, if f satis es the locally fuzzy contractivity condition then it satis es the global fuzzy contrac-tivity condition.

Copyright©The Oceanographic Society of Japan/TERRAPUB/Springer where u∗ is the friction velocity of the air, ρa is air density. U10 is the wind speed at 10 m height above the sea surface in neutral stratification condition; CD is the drag coefficient. Many studies have shown that air-sea exchange is regulated by turbulence associated with wind and wind waves at the air-sea interface (Jähne et a...
