A novel method for narrowing microfluid width in microchannel is presented by utilizing of air boundaries of which inflation direction is perpendicular to microfluid flow. The air boundaries are generated by heating water with microheater. The microfluid width of 300 pm can be focused and maintained as up to 22 pm which is near cell size without affecting cell or microchannel structure. The nar...

The current study was conducted to compare and contrast the uses of 2 devices (temperature transponder or infrared thermometer) and their locations (inner air cell membrane or outer eggshell surface) in Ross × Ross 708 broiler hatching eggs. The air cells of 14 embryonated and 10 nonembryonated eggs were implanted with temperature transponders on d 13.5 of incubation. Likewise, for these same e...

The mastoid air cell system represents a more or less extensive system of interconnecting air filled cavities arising from the walls of the mastoid antrum and walls of the middle ear. Allam (1969) classified the pneumatized spaces of the temporal bone into five different regions: middle ear region, mastoid region, perilabrynthine region, petrous apex region and accessory region. This air cell s...

Qualitatively, it is known that the reactants content within the catalyst layer (CL) is the driving moments for the kinetics of reaction within the CL. This paper aimed to quantitatively express the level of enhancement in electrical power due to enrichment in the oxygen content. For a given MEA, a flow field (FF) designer is always willing to design a FF to maximize the content of oxygen in al...

The objective of this study was to investigate the cooling performance characteristics of an electrical air conditioning system using R744 as an alternative of R-134a for a fuel cell electric vehicle. In order to analyze the cooling performance characteristics of the air conditioning system using R744 for a fuel cell electric vehicle, an electrical air conditioning system using R744 was develop...

Inflammation is an essential physiological response to infection and injury that must be kept within strict bounds. The IL-10/STAT3 anti-inflammatory response (AIR) is indispensable for controlling the extent of inflammation, although the complete mechanisms downstream of STAT3 have not yet been elucidated. The AIR is widely known to extend to other myeloid cells, but it has best been character...

PURPOSE To compare the big-bubble method using air and liquid as medium of separation for Descemet membrane endothelial keratoplasty (DMEK) lenticule preparation in an eye bank. METHODS Donor corneas (n=20) were immersed in liquid [tissue culture medium (TCM)]. Air and liquid was injected using a 25-gauge needle in the posterior stroma or as near to the stroma-Descemet membrane (DM) phase as ...

The concept of genetic susceptibility factors predisposing cigarette smokers to develop emphysema stems from the clinical observation that only a fraction of smokers develop clinically significant chronic obstructive pulmonary disease. We investigated whether Smad3 knockout mice, which develop spontaneous air space enlargement after birth because of a defect in transforming growth factor-β (TGF...

A study of detonations in high-molecular weight hydrocarbon fuels of interest to pulse detonation engine applications was performed in a 280 mm diameter, 7.3 m long facility. Detonation pressure, wave speed, and cell width measurements were made in JP-10 mixtures and in mixtures representative of the decomposition products of JP-10. Experiments were performed in vapor-phase JP-10 mixtures at 35...

Increase in air or oxygen pressure in microbial cell cultures can cause oxidative stress and consequently affect cell physiology and morphology. The behaviour of Saccharomyces cerevisiae grown under hyperbaric atmospheres of air and pure oxygen was studied. A limit of 1.0 MPa for the air pressure increase (i.e. 0.21 MPa of oxygen partial pressure) in a fed-batch culture of S. cerevisiae was est...
