Due to the variety of products, simultaneous production of different models has an important role in production systems. Moreover, considering the realistic constraints in designing production lines attracted a lot of attentions in recent researches. Since the assembly line balancing problem is NP-hard, efficient methods are needed to solve this kind of problems. In this study, a new hybrid met...

Is there a relationship between local arts and culture production and local prosperity that is permanent rather than transitory? The answer to this question determines whether arts and culture production generates economic growth or a temporary ‘multiplier’ effect that diminishes over time. We argue that despite the obvious public policy interest in the subject there has been no fully satisfact...

In the present study, the effects of four factors including initial sulfide concentration (mg l-1 ), agitation speed (rpm), amount of inoculums (%) and sodium concentration (mg l-1) on removal efficiency (%R) and yield of sulfate production by Thioalkalivibrio versutus from synthetic spent caustic were investigated. For this purpose, experiments are designed by design of experiments (DOE) and R...

This illustrated paper reports on the early digital games industry in New Zealand, during the late 1970s and 80s. It presents an overview of this largely unknown history, drawing on in depth archival research, interviews with key industry participants and collectors. It discusses the local production of consoles, handhelds, and arcade games in this market, as well as anomalies of distribution o...

Introduction: It has been approved that in most tissues NO production increases during acute inflammation and Angiotensin II has a role in production of reactive oxygen species (ROS). As regulation of joint blood flow (JBF) is important in this situation, this study was performed to investigate the interaction of local Ang II and ROS production and the modulatory role of NO on regulation of JBF...

background; feather waste is generated in large amounts as a by-product of commercial poultry processing. the main component of feather is keratin. the main purpose of this study was to identify bacillus spp. (the keratinolytic bacteria) that are able to degrade the feather for producing keratin. methods; bacillus spp. were isolated from the waste of poultries located in miyaneh city. the bacte...

background and objectives: bacteria, most prevalently the pseudomonas species possess high capacity to utilize and de- grade petroleum hydrocarbons and are classified as the hydrocarbonoclastic microorganisms. many species of the genus pseudomonas are notorious for their aerobic degradation capacity, extracellular enzyme production and are metabolically versatile organisms capable of utilizing ...
