In many cases economic optimal operation is the same as maximum plant throughput, which is the same as maximum flow through the bottleneck(s). This insight may greatly simplify implementation. In this paper, we consider the case where the bottlenecks may move, with parallel flows that give rise to multiple bottlenecks and with crossover flows as extra degrees of freedom. With the assumption tha...

in this paper, we apply the local fractional adomian decomposition and variational iteration methods to obtain the analytic approximate solutions of fredholm integral equations of the second kind within local fractional derivative operators. the iteration procedure is based on local fractional derivative. the obtained results reveal that the proposed methods are very efficient and simple tools ...

poultry products are considered as one of the most important sources of food for humans, worldwide. indigenous poultry production has grown in popularity among villagers and some urbanites due to simple maintenance conditions, adequate adaption of poultry to different climatic conditions, and acceptable product yield. parasites are among the main pathogenic agents, threatening the health of pou...

background and objectives: the aim of our study was to characterize gizzard lactobacillus fermentum-group strains on the basis of their phenotypic profiles regarding characteristics of lactobacilli. in addition, their in vitro potential probiotic properties were evaluated. materials and methods: the lactic acid bacteria were isolated and identified from gizzard contents of algerian local poultr...

one of the important issues in hydraulic engineering is inspection of local scour depth around bridge pier. using piles is one of the ways for confronting local scour and erosion. in this study, the experiments were conducted in an 8m long, 0.5m deep and 0.25m wide flume. and the effectof using piles and number of them observed on the amount of scour in three different frude numbers. the shape ...

iran has a long history in the use of medicinal plants and traditional medicine. local people in the villages, especially the elderly, have useful information about health benefits and how to use these plants. therefore, it seems that collecting and recording this information leads to the revival of this traditional knowledge. the current research is an ethnobotanical study on the medicinal pla...
