DEVELOPMENT OF A MULTIFUNCTIONAL COOKING APPLIANCE: EVALUATION OF FOOD QUALITY INDEXES AND COOKING FUNCTIONS.
… using convection air in prototype oven versus water bath methods and traditional cooking techniques. Quality attributes of animal products (tenderloin beef and salmon) and vegetable products (carrots) were assessed. LTLT air cooking of animal products showed potential for achieving tenderness …

Viscoelastic characterization of collagen-GAG scaffolds
… the determination of viscoelastic linearity, a water bath was designed in the hopes of performing stress relaxation tests in hydrated environment with the temperature maintained at 37°C, the temperature of the human body. These tests will aid in the future studies of how cells contract and apply …

How do trees die following low intensity fires: Exploring the hydraulic death hypothesis
… Secondly, changing surface tension as water is heated has also been shown to increase the chance of cavitation. The final mechanism is a reduction in conductance as a result of direct xylem vessel deformation due to the visco-elastic properties of xylem walls (lignin). In order to …

The effects of hand and forearm cooling on self-paced cycling performance in the heat.
… their forearms and hands in a circulating water bath at 10°C, 20°C, or a 32∘C (control) throughout the TT. Performance, physiological, and perceptual measures were collected. Results showed no significant differences in time to completion, power output, pacing strategy (p=0.488), core …

Improving the Exfoliation of Layered Silicate in a Poly(ethylene terephthalate) Matrix Using Supercritical Carbon Dioxide
… mixed in a single screw extruder, cooled in a water bath and pelletized. Two sets of samples each containing layered silicate with different surface chemistries were produced with this method at 1, 3 and 5 wt% silicate. For comparison, samples of the same weight fraction and type of silicate …

Thermal inactivation of Salmonella and Escherichia coli O157:H7 in heat treated, recycled used cooking oil
… were exposed to heat at 62, 71, or 82°C using a water bath fitted with a circulator. At predetermined time intervals, individual samples were removed from water bath and immediately chilled in an ice bath. Samples were diluted in 0.1% buffered peptone water supplemented with 1% emulsifier (Tween …
