Steel Bridge Design Handbook - Limit States Volume 10
The fatigue-and-fracture limit state is treated separately from the strength and service limit states since it represents a more severe consequence of failure than the service limit states, but not necessarily as severe as the strength limit states. Fatigue cracking is certainly more serious than ... Read Full Source

11 Winter Produce Picks That Pack A Health Wallop
Apart from containing a healthy dose of immunity-boosting vitamin C and lycopene, this in-season citrus fruit may help prevent winter weight gain. In a 2014 animal study from the University of California--Berkeley, regular consumption of grapefruits triggered weight loss as well as lowered blood sugar and insulin levels. Researchers believe a flavonoid in grapefruits, called naringin, is to ... Read News
