in this paper, a multi-period and multi-resource operating room (or) scheduling and rescheduling problem with elective and semi-elective (semi-urgent) patients is addressed. a scheduling-rescheduling framework based on the so-called rolling horizon approach is proposed to solve the problem. the core of the proposed framework is a novel proposed mixed-integer linear programming (milp) model with...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
Staphylococcus aureus is one of the most prevalent causes of gastroenteritis worldwide. Knowing the precise boundary for the growth/no growth interface of S. aureus and also determining the period of time needed for bacterial growth initiation is necessary for food safety risk assessment. This study was designed to examine the combined effects of temperature, acetic acid, inoculum level and NaC...
beet armyworm (spodoptera exigua (hubner)) (lepidoptera: noctuidae) is the most economically important sugar beet (beta vulgaris) pest worldwide. the main control method of this pest is insecticides use. thus, it is important to develop alternative means of controlling this pest, including host plant resistance using plant lectins. in the current study, the effects of gna (galanthus nivalis agg...

The present study was carried out to examine the effects of a vitamin premix (VP) reduction or withdrawal from finisher diet (29-43 days) on performance, immuno-competence, and characteristics of leg bones and meat lipid oxidation of chickens fed on corn-soybean meal based diet. A total of 900 male broiler chickens (Ross 308) were allocated to five treatment groups (0, 33%, 66%, 100% and 133% V...
Introduction: Research has shown that gold nanoparticles (AuNPs) can damage the physiological processes of brain tissue. Given the antioxidant properties of gingerol (GING), this study aimed to determine the protective effect of 6-gingerol on hippocampal levels of brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), DNA oxidative damage, and the amount of Bax and Bcl2 apoptosis ...
