The main disadvantage of biodiesel is its high price. The price of biodiesel depends on various factors such as the price of oil, methanol, catalyst, and labor. Among dif-ferent economic factors, oil accounts for the largest share of input costs of biodiesel production. In this study, first, suitable heterogeneous catalysts were identified for biodiesel production. Several studies were carried ...

duction: Iron deficiency anemia is the most common nutritional problem among children. This condition has affected approximately 48% of infants, worldwide. Given the importance of physical and mental development of young children, it is important to prevent this disease in order to prevent the loss of children’s abilities. The aim of this study was to determine the effect of PRECEDE model on ir...

This paper discusses the simulation study carried out for proposing one-piece lean line layout with features of Lean Manufacturing. The lean initiatives that can be addressed are, introducing Kanban replenishment sys-tem, better work-in-process, changing the layout, visual management techniques, standardized work for the re-duction of cycle time, number of workers, number of setups. To improve ...

The experience was laid fields Department Agriculture Crop Production Federal Rostov Agricultural Research Centre. objects research are elements pea productivity, yield protein content in grain, applied seeding rate. Statistical anal...

Objective: The development of the ship hull assembly pro-cess is possible by changing method basic parts at building site, which would shorten duration process and lead to cost reduction. One pos-sibilities increase dimensions mass units, as well crane capacity site. Methods: Ship methods involving sections, blocks modules are used in phase. In world’s best shipyards, ships built from or module...

This paper presents a genetic algorithm (GA) for solving a generalized model of single-item resource-constrained aggregate production planning (APP) with linear cost functions. APP belongs to a class of pro-duction planning problems in which there is a single production variable representing the total production of all products. We linearize a linear mixed-integer model of APP subject to hiring...
