Improper food cooling practices are a significant cause of foodborne illness, yet little is known about restaurant food cooling practices. This study was conducted to examine food cooling practices in restaurants. Specifically, the study assesses the frequency with which restaurants meet U.S. Food and Drug Administration (FDA) recommendations aimed at reducing pathogen proliferation during foo...

purpose: to compare post-operative pain with cooling photorefractive keratectomy (prk) versus conventional prk. methods: a prospective clinical trial was performed on 94 eyes from 47 patients scheduled for prk. patients were randomly assigned to either cooling or conventional prk. pain was evaluated 6, 12, 24 and 48 hours post-operation using a visual analogue scale (vas). corneal haze, conjunc...

Various ograns under condition of hypothermia undergo a marked change in their response, both to physiological and pharmacological stimuli although the e:uct mechanism underlying this alteration yet remains unex· plained. As a result of more generalised use of induced hypothermia as an adjuvant in cardiac surgery, it was noted that lowering of body temperature predisposes to cardiac arrhythmias...

over a period of three months (summer), 108 samples of water collected from four hospitals in te-hran. they were taken from numerous potable and non-potable water, including main supply cis-terns, calorifiers, hot and cold tap water, shower, cooling tower and drain of air condition system. culturing of concentrated and non-concentrated water samples on buffered charcoal yeast extract (bcye) aga...

the effect of shear rate on dissolution of carbon dioxide in viscoelastic wheat flour matrix and cell density in a glass barrel twin screw extruder is investigated. it is found that by increasing the shear rate there will be a decrease in the required thermodynamic conditions and hence, it improves blowing agent dissolution and increases the cell density. shear rate breaks up big bubbles and he...

Abstract: Cooling slope-casting processing is a relatively new technique to produce semisolid cast feedstock for the thixoforming process. Simple equipment, ease of operation, and low processing costs are the main advantages of this process in comparison with existing processes such as mechanical stirring, electromagnetic stirring, etc. The processing parameters of cooling slope casting are...

Here, we address the question of why some people have a greater chance of surviving and/or better resistance to cold-related-injuries in prolonged exposure to acute cold environments than do others, despite similar physical characteristics. The main aim of this study was to compare physiological and psychological reactions between people who exhibited fast cooling (FC; n = 20) or slow cooling (...

the wind pressure is one of the important loads on cooling towers which can be computed via numerical solution of the wind flow. in this paper, the effects of turbulent modeling on accurate computations of wind pressure on a cooling tower with base structure are investigated. for this propose, the results of a finite element flow solver using various commonly used turbulence models are compared...

The locus coeruleus (LC) is a chemoreceptive brain stem region in anuran amphibians and contains neurons sensitive to physiological changes in CO2/pH. The ventilatory and central sensitivity to CO2/pH is proportional to the temperature in amphibians, i.e., sensitivity increases with increasing temperature. We hypothesized that LC neurons from bullfrogs, Lithobates catesbeianus, would increase C...
