introduction: in this study human follicular fluid has been used as an enzyme- rich solution to prevent embryo implantation in mice which resulted in reduction of pregnancy rate. materials & methods: 2-6 month nih female mice were used to study the effect of interauterine follicular fluid on the fertility rate. 226 plugged female mice were caged in three groups: control, placebo, and experiment...

BACKGROUND Blind injection of the subacromial-sub-deltoid bursa (SSB) for diagnostic purposes (Neer test) or therapeutic purposes (corticosteroid therapy) is frequently used. Poor response to previous blind injection or side effects may be due to a misplaced injection. It is assumed that ultrasound (US)-guided injections are more accurate than blind injections. In a randomized study, we compare...

BACKGROUND Ibuprofen is the most commonly used nonsteroidal, antipyretic, antiinflammatory analgesic in children. Nonsteroidal, antipyretic, antiinflammatory analgesics act in both the peripheral tissues and the central nervous system. The central nervous system penetration of ibuprofen has been described in adults but not in children. OBJECTIVES Our goals were to investigate the cerebrospina...

a methodology is presented in this paper to find optimal location and dosage of chlorine injection in water distribution networks. the objective is to minimize the chlorine consumption while keeping the residual chlorine at each node within the standard range. unfortunately because of wrong water quality management in water distribution networks in many parts of the world, many problems such as...

The first reported hybrid artificial neural network-genetic algorithm (ANN-GA) approach for the optimization of on-capillary dipeptide derivatization is presented. More specifically, genetic optimization proved valuable in the determination of effective network structure with three defined parameter inputs: (i) phthalic anhydride injection volume, (ii) time of injection, and (iii) voltage, for ...

the integration of an approximate model and a clonal selection algorithm (csa) is considered to one of the most effective ways to solve complex optimization design problems in engineering. in this study, first, a process for developing an approximate model and the principles of clonal selection algorithms were presented. then, a variotherm temperature injection mold used to produce a large liqu...

the aim of this study is to find the optimal water pressure and percentage of supply vapour in the feed water heaters (fwhs) of steam power plants, such that they maximize the thermal efficiency of the rankine cycle within pre-specified values of minimum and maximum pressures of the thermodynamic cycle. thermal efficiency is defined as a function of unknown variables (fluid pressure and vapour ...
