carcass yield is important economical parameters for producers and contributors of meat science. in the present study, carcass yield and also the weight losses resulted post mortem until consumption were investigated. the mean values of cold carcass and hot carcass weight were 15.63 and 15.33, the mean value of cooling loss was 1.87% and average value of hot and cold efficiency were 41.44% and ...

temperature restrictions on aqueous effluents dictate that streams with a temperature higher than the permitted level needed to pass through cooling systems to reduce the effluent temperature before discharge. in this study, by considering the grouping design rules based on pinch technology, an optimum design for a distributed effluent cooling system, has been developed. a counter-flow wet cool...

a thermodynamic analysis of the counter flow wet cooling tower (cwct) in the steelmaking unit of the khuzestan steel company (ksc) is performed in this paper. we evaluated both energy and exergy formulations for analyzing the heat and mass transfer, exergy and second-law efficiency in this cooling tower. the lewis factor le f is an indication of the relative rates of heat and mass transfer in a...

effects of three pressure reduction rates (prr) of 103 pa s-1, 197 pa s-1, and 347 pa s-1 on temperature distribution and variation, moisture content, and sensory quality of steamed stuffed buns were investigated after vacuum cooling. the distributions and variations of surface temperatures were determined by the thermal infrared imaging method. the temperature profiles presented significant di...

A two-dimensional mathematical model was developed to estimate the contributions of different mechanisms of brain cooling during cold-water near-drowning. Mechanisms include 1) conductive heat loss through tissue to the water at the head surface and in the upper airway and 2) circulatory cooling to aspirated water via the lung and via venous return from the scalp. The model accounts for changes...

The effect of vacuum pre-cooling process on leaf lettuce was a complex process of heat and mass transfers. Based on the physical properties of leaf lettuce in vacuum pre-cooling process, an unsteady computation model was constructed to analyze the factors affecting vacuum pre-cooling. Some factors such as the pre-cooling temperature, pressure and quantity of the spray-applied water were verifie...

BACKGROUND Chemotherapy-induced temporary hair loss is one of the most common and distressing side-effects of cancer therapy. Scalp cooling to reduce this hair loss is a controversial issue for many doctors and nurses. This may be due to inadequate knowledge. METHODS This review from 53 publications and three personal communications focuses on the efficacy of the treatment, side-effects, poss...

BACKGROUND Cooling the lower abdomen is one of the Japanese traditional non-pharmacological prophylactic managements for postpartum hemorrhage. This study aimed to evaluate the effectiveness of cooling the lower abdomen in reducing postpartum blood loss compared with no intervention. In both cases, women delivered vaginally without prophylactic oxytocin in the third stage of labor. METHODS In...
