This work presents a continuous-time mixed-integer linear programming (MILP) formulation to find the best detailed schedule for single-source multi-product pipelines, minimizing the total operating costs. By knowing the aggregate plan including pumping and delivery tasks, the best detailed solution tends to minimize pump stoppage/restart costs as well as pumping energy charges associated to the...

A component stockout during the assembly process is one of the most undesirable events that can occur since the resulting line stoppage is associated with extremely high costs. In this paper we address the problem of allocating space to components along the line, subject to practical constraints. The objective is to maximize the line fill-rate; namely, the probability of no line stoppages due t...

Kutishwar Haldar, H. M., 50, was admitted into the Rajbari Hospital on the 21st August last for the treatment of severe pain in passing urine, attended with discharge of blood. History of the case.?About a year before lie first noticed a severe burning pain over the region of the bladder; this pain gradually began to increase and was intense, especially after micturition; from 'this time he not...

The causes of imminent abortion are multi-factorial. The biggest causal factor is the low level of serum progesterone level. The lowest critical level of serum progesterone for survivability of pregnancy is 10 ng/ml. Eighty percent of patients experiencing abortion showed that their progesterone level was < 10 ng/ml. Patients who realized that their pregnancy would experience hemorrhage general...

This paper develops an effective joint production, setup and maintenance control policies in an unreliable one-machine two-products manufacturing system. The main objective is to reach a higher synchronization level of the preventive maintenance (PM) interventions in the planning of production activities. The proposed joint control policy integrates the concept of the opportunistic maintenance ...

A-55-year-old man with diabetes mellitus was admitted to hospital because of chest pain. He was diagnosed as anterior acute myocardial infarction and treated with stent placement. After 7 days, ventricular fibrillation occurred because of a subacute reocclusion and balloon angioplasty was performed. Despite reperfusion therapy, intraaortic balloon pumping, antiarrhythmic drugs and beta-blocker,...

INTRODUCTION Wide awake surgery of the hand (WASH) is a well-accepted technique in hand surgery which allows the surgeon to identify and rectify on the table of some of the inadvertent shortcomings in the surgical procedures to optimise the final outcome. The advantage, however, precludes the use of tourniquet. We describe a modified method which preserves all the advantages of WASH and allows ...
