The indoor environment of the operating room has a significant impact on health personnel. Compared with pollutants released from occupants, amount generated by surgical equipment is greater, which easily affects patients and doctors. In this study, local exhaust ventilation (LEV) applied to an LEV mounted near operation zone remove smoke equipment. CFD technique used concentration reduction po...

We demonstrate selective fixing of volume holograms in photorefractive media. Each holographic page may be fixed individually and overwritten without destroying the other fixed pages. We present experimental results describing this process in Cr-doped Sr(0.75)Ba(0.25)Nb(2)O(6) at room temperature, with hologram lifetimes exceeding 100 days during continuous readout with an intense beam (1 W/cm(...

In aqueous medium at room temperature Ag(I) forms a metallogel with vanadate ions which doesn't have any carbon in the gel skeleton. The serendipitously discovered inorganic gel, which involves a reasonably large volume of water, is capable of sequestering gas, dye and toxic pollutants from water bodies.

some amide derivatives have been synthesized by the reaction of corresponding nitriles with potassium tert-butoxide as a nucleophilic oxygen source under ultrasonic irradiation. this new methodology provides good to excellent yields in short reaction times (15-90 min) at room temperature.

this study was initiated to assess the effectiveness of designating smoking rooms to control environmental tobacco smoke in nursing homes. of the 39 nursing homes located in toledo (a city in ohio, usa) included in the preliminary survey, 33 facilities (85%) allowed smoking, 14 facilities (36%) allowed indoor smoking, and 13 facilities (33%) provided a designated smoking area. three of these 13...

the operating room. Non-enzymatically isolated stromal vascular fraction contained cells expressing CD44, CD73, CD90 and CD105 that when expanded in culture differentiated along adipogenic and osteogenic lineages. When compared to enzymatic isolation, mechanical isolation methods required less time but produced lower cell yields. Two articles reported improved volume retention in fat grafts sup...

Carbon dioxide (CO2) is an established alternate angiographic contrast agent, which can be delivered by pump or hand injection. We describe a simple, safe and inexpensive hand injection system that delivers a known volume of CO2 at atmospheric pressure and prevents contamination with room air.

We present results for a photonic microwave resonator designed and fabricated at 17.4 GHz with a record high Quality factor (Q=26,400) at room temperature over a mode volume smaller than one cubic wavelength. The cavity is uniquely designed to have its electric field concentrated in air, which allows for efficient coupling to free space and facilitates interactions with gaseous atomic systems a...

The flexible metal-organic framework MIL-53(Cr) undergoes a dramatic volume expansion upon immersion in water at room temperature to form a crystalline hydrate in which water is held as a hydrogen-bonded tube: the hydration is readily reversible under ambient conditions as shown by time-resolved powder X-ray diffraction.
