Introduction: Higher personal mastery is associated with better physical functioning, wellbeing, and longevity among older populations. However, few studies have focused on whether personal mastery is protective against mortality among older adults living with diabetes over time.  Methods: A total of 1,779 participants were identified from an off-year survey of the Health and Retirement Study....

Summary The unsteady reflection of dam-break flow along a horizontal channel by remote barrier is modelled using the nonlinear shallow water equations. interaction generates an upstream moving bore that connects collapsing reservoir fluid to rapidly deepening layer adjacent barrier. These motions are modified when released into containing pre-wetted layer, because oncoming itself headed alters ...

In dynamic social networks, agents are able to make and break connections with neighbors to improve their payoffs. Rules have recently developed which help agents evaluate their neighbors and decide whether to break a connection. These rules have introduced the idea of tolerance in dynamic networks by allowing an agent to maintain a relationship with a bad neighbor for some time. In this resear...

Researchers have always aimed to break the trade-off relationship between strength and ductility. In this study, a carbon diffusion strategy was provided improve ductility of composite martensite steel simultaneously, as well increase uniform by 190%. The process strengthens without losing hardening ability austenite constituents brings in substantial transition layer. This can also be applied ...

an experiment was conducted to evaluate the effects of some technological processes on the residual levels of imidacloprid in strawberry fruits and products. according to their half-life (t1/2) values, strawberry fruits can be safely harvested for human consumption 7.4 days after spraying. the removal ratio of imidacloprid residue in strawberries was in the range of 9.9–30.55% by washing with t...

Peripheral intravenous (IV) catheters can break off while still in the patient, with possible detrimental effects such as upstream migration to the heart. These catheters have probably been damaged by the needle during a difficult insertion. A peripheral IV catheter was removed in a 90 year old patient and only half of the catheter was retrieved. By using ultrasound examination the remaining pa...

Cycles play an important role when analyzing market phenomena. In many markets, both overlaying (weekly, seasonal or business cycles) and time-varying cycles (e.g. asymmetric lengths of peak and off peak or variation of business cycle length) exist simultaneously. Identification of these market cycles is crucial and no standard detection procedure exists to disentangle them. We introduce and in...
