ResultsThe optimal processing technology was that the ratio of quercetin to PEG was 1∶3,the temperature of drug liquid was(90±5)℃,the droping velocity was 30 drops/min and the temperature of coolant liquid was(15±2)℃.
With static models (including end control, oxygen feeding control, slag making control, bottom blowing control) and dynamic models (for decarburization speed, molten steel heating and quantity of mixed cooling agent) used in converter steel-making the pressure tolerance at mouth can be decreased, gas recovery increased.
The cryoablation was performed with the Cryocare system (Endocare, USA) by using argon gas as a cryogen. Temperature in target tissue reached -160℃ for 10 to 15 min, and then, helium was sent to increase the temperature to 20℃. Two freeze-thaw cycles were performed.
A sublimating pastelike cooling agent on the basis of ammonium oxalate is used.
It is demonstrated that the injection of the products of decomposition of cooling agent on the insulating walls has no effect on the power performance of the channel.
A new scheme of using porous metallic materials (PMs) for cooling laser diode bars is proposed, which provides for a two-dimensional regime of heat removal and reduces the effective filtration length of a cooling agent.
An approximate solution is given for the temperature distribution in a porous body bearing a flow of cooling agent which undergoes a phase transition.
Unique features of He II as a cooling agent as compared to He I are noted and discussed.
The effect of the thermophysical parameters of a cooling medium on the macrokinetics of secondary physicochemical processes that occur in a hermetic chamber after the explosion of a solid explosive charge is studied.
One of these is the effective temperature of the cooling medium; the other is a time constant of the cooling process uniquely related to the heat dissipation coefficient.
The module itself was heated by a GC oven and cooled down by an external cooling medium.
After one minute the cooling medium is turned off, the pre-column rapidly heats in the column oven and a sharp reinjection of the sample occurs.
The cooling medium used was liquid nitrogen, liquid argon, or a dry ice-acetone slurry (197 K).
The ratio between recombination coefficients corresponding to the thermal-collisional and Lax capture mechanisms is calculated at different degrees of compensation at a cryogen temperature (T = 4.2 K) for n-type semiconductors.
Analytical expressions are obtained for the longitudinal temperature profiles of the wall and the stream of cryogen during the cooling of a cryogenic pipeline.
Thaw drip loss and protein characterization of drip from air-frozen, cryogen-frozen, and pressure-shift-frozen pork longissimus
A high molecular weight protein band (Mw 97,000) characteristic for gel electrophoresis (SDS-PAGE) for drip from fresh, air-frozen, and cryogen-frozen pork was not present in drip from pressure-shift-frozen pork.
A precision of 0.3?ppb?Hz-1/2 is obtained using a thermoelectrically cooled detector, which allows continuous unattended operation over extended time periods with a totally cryogen-free instrument.
