متن کاملInsulin and atheroma.
Many clinical studies have shown an increased insulin response to oral glucose in patients with ischemia of the heart, lower limbs, or brain. Hyperinsulinemia also occurs in patients with angiographically proved atherosclerosis without ischemia and thus appears to be related to arterial disease and not to be a nonspecific response to tissue injury. Fasting insulin levels and insulin responses t...
متن کاملStability of Retrial Queues with Versatile Retrial Policy
We consider in this paper the stability of retrial queues with a versatile retrial policy. We obtain sufficient conditions for the stability by the strong coupling convergence to a stationary ergodic regime for various models of retrial queues including a model with two types of customers, a model with breakdowns of the server, a model with negative customers, and a model with batch arrivals. F...
متن کاملFats and Cancer
relationship between dietary fat and cancer, it would appear that a low fat intake is advisable although, as we hope to discuss below, dietary advice cannot be too dogmatic concerning specific fats. Many dietary factors are implicated in cancer. In the first place, amongst the seemingly harmless substances we consume such as black pepper, mushrooms, celery, parsnips, toast, caffeine and alcohol...
متن کاملA Single Server Retrial Queue in Bernoulli Schedule With Feedback on Non-Retrial Customers
In this paper, we consider an M/G/1 retrial queue with Bernoulli feedback and general retrial times where the external arrivals blocked either with probability q join the infinite waiting room called non-retrial queue or with probability p, (p+q = 1) leave the service area and enter the retrial group called orbit in FIFO discipline. Also we assume that only the customer at the head of the orbit...
