This comprehensive work explores the research performed inoptimization of the collection bin and in recycle bin location-allocation issues in solidwaste management. Although the collection phase of solid waste management accountsfor a significant proportion of the municipal budget, it has attracted only limitedattention of the researchers. Optimization of the collection bin and recycle bin loca...

The development of organometallic catalysts with high activity and selectivity has transformed the way both bulk and fine chemicals are produced. When such catalysts are applied in fine chemicals production, the presence of toxic heavy metals in these catalysts (Pd, Pt, Ru, Rh, etc.) can pose significant separation challenges. Regulatory bodies (such as the FDA and EMA) require that many popula...

We have investigated whether rat motor nerve terminals with different in vivo activity patterns also have different vesicle trafficking characteristics. To do this, we monitored, using combined optical and electrical techniques, the rate of exocytosis (during different frequencies and patterns of activity), the releasable pool size, and the recycle time of synaptic vesicles in terminals on sole...

Municipalities worldwide are under increasing pressure to reduce the amount of solid waste ending up in landfills. One way of doing so is to increase household participation in recycling. Although existing research identifies several factors affecting household recycling behaviour, South Africa poses a unique situation with regard to attitudinal and spatial factors. Socio-political transformati...

In this study, the effect of recycling fuel cell products on the performance of a solid oxide fuel cell and gas turbine (SOFC-GT) hybrid system was investigated. Three types of products recycling are considered: cathode products recycling (CPR), anode products recycling (APR), and both cathode and anode products recycling (BACPR). In the present work,   operating temperature and  limiting curre...

one of the main disadvantages of anaerobic wastewater treatment at a low ph is the significantoperational cost due to the addition of necessary alkali. to reduce alkali supplement and thus the cost, thisstudy proposes a sequential multi-feed (sqmf) mode (distributed feeding) and effluent recycle (er) mode.experiments were conducted with a pilot-scale (2.5 m3) thermophilic (55°c) multi-staged up...
