The antioxidant ability of vitamin B12 (VitB12) and its effects on motility characteristics fresh chilled ram spermatozoa were investigated. Three concentrations VitB12 including 1, 2 4 mg/ml added to tris media samples collected from five Awassi rams incubated in these at 37 5 °C for 24 hours respectively. Formation hydrogen peroxide (H2O2) was estimated using a fluorometric assay analyzed com...

Our objectives were to examine the effects of prerigor excision and rapid chilling vs. conventional carcass chilling of two muscles on proteolysis and tenderness during the postmortem storage, as well as the effects of fast and slow rates of cooking on myofibrillar characteristics and tenderness. The longissimus thoracis (LT) and triceps brachii (TB), long head muscles were removed 45 min after...

As U.S. lamb imports increased relative to domestic production, and the relative share of chilled to frozen lamb imports increased, importers of chilled lamb have become less responsive to domestic and import prices, while the direct opposite is the case for frozen lamb imports. From 1990 to 2003, chilled lamb imports from Australia and New Zealand became less and less responsive to U.S. prices...

INTRODUCTION Chilled saline is commonly used to irrigate the ocular surface after photorefractive keratectomy (PRK) and is often considered by the patients to be uncomfortable. Room temperature (non-chilled) saline may be a safe and less painful alternative. OBJECTIVES To compare pain and visual outcomes after irrigating the ocular surface with chilled saline versus room temperature saline in...

This paper presents a new approach to control variables in chilled water loops for energy conservation. Based on the analysis of the relationships between differential pressure and chilled water flow rate in chilled water loop, a series of optimal set points can be found to reset the controlled variables. With these reset set points, chilled water pumps only provide the necessary energy for wat...
