در این مقاله یک مدل برنامه ریزی غیرخطی چند هدفه برای فشرده سازی زمانارائه گردیده است که هدف اصلی آن عبارت است از حداقل سازی pert شبکه هایبا صرف بودجه بیشتر در فعالیتهایی pert زمان بدبینانه فعالیتهای بحرانی در شبکه هایاست که در مسیر بحرانی قرار دارند. در واقع، این مدل نشان دهنده نحوه تخصیصبودجه بین فعالیتهای مسیر بحرانی است که در نهایت نشان می دهد، کاهش زمانبدبینانه فعالیتهای بحرانی باعث کاهش زم...

The Engineering Education Research (EER) Peer Review Training (PERT) project aimed to develop EER scholars’ peer review skills through mentored experiences reviewing journal manuscripts. Concurrently, the explored how scholars capabilities for evaluating and conducting scholarship reviewing. PERT used a mentoring structure in which two researchers with little experience were paired an experienc...
In this paper, we develop an acyclic network of queues for the design of a dynamic flow shop, where each service station represents a machine. The orders arrive at the input station according to a Poisson process, assuming each order consists of n jobs. Jobs associated with successive orders contend for resources on a FCFS (First Come First Served) dispatching rule in all machines. Upon arrivin...
BACKGROUND Most cystic fibrosis (CF) patients have exocrine pancreatic insufficiency (EPI) and need supplementation with pancreatic enzyme replacement therapy (PERT). Liprotamase, a novel non-porcine PERT containing highly purified biotechnology-derived lipase, protease, and amylase, has successfully undergone initial efficacy and safety testing. METHODS In this international phase III parall...

Nowadays, most important projects are studied by project network methods but, unfortunately, gaps and deviations between the theoretical results and the achieved ones tend to be systematically large. Traditionally modelling of uncertainty has been based on the assumption that the duration of each activity follows an independent random variable as it is the case of PERT. However, this model is t...
Fatigue impairs sensorimotor performance, reduces spinal reflexes and affects the interaction of antagonistic muscles in complex motor tasks. Although there is literature dealing with the interference of fatigue and postural control, the interpretation is confounded by the variety of paradigms used to study it. This study aimed to evaluate the effects of postural fatigue on balance control and ...
Enzyme replacement therapy has been used successfully in many lysosomal storage diseases. However, correction of brain storage has been limited by the inability of infused enzyme to cross the blood-brain barrier. The newborn mouse is an exception because recombinant enzyme is delivered to neonatal brain after mannose 6-phosphate receptor-mediated transcytosis. Access to this route is very limit...
The objective of this study was to evaluate the probability norovirus foodborne illness by raw oyster consumption. One hundred fifty-six samples were collected examine prevalence. inoculated with murine and stored at 4°C-25°C. A plaque assay determined titers. titers fitted Baranyi model calculate shoulder period (h) death rate (Log PFU/g/h). These kinetic parameters a polynomial as function te...
