Sustainability of the rice–wheat rotation is important to Asia’s food security. Intensive cropping with no return of crop residues and other organic materials results in loss of soil organic matter and is not sustainable. We evaluated effect of eight treatments comprised of various combinations of green manure (GM), wheat straw (WS), rice straw (RS), farmyard manure (FYM) and urea alone (contro...

Design teams’ work is greatly influenced by green building rating systems (GBRSs). Early GBRSs that had an energy- or resource-based hierarchy and prioritized mechanical components active technologies were unable to adequately support the architectural design (AD). Due recent rise in awareness of importance AD creation GBs, many may now improve requirements pertaining AD. However, it has not be...

The contradiction between economic development and environmental deterioration makes people begin to have a further understanding of the ecology and environment. To promote effective development of reverse logistics and implementation, according to general activity process of manufacturing enterprises, this paper builds the manufacturing system model of reverse logistics. On the basis of activi...

Diode pumped solid state (DPSS) Q-switched nanosecond pulsed lasers are becoming the laser of choice for a wide variety of processes in printed circuit board (PCB) manufacturing. Lasers are being used today in PCB manufacturing for via drilling, depaneling, profiling (cutting), laser direct imaging (LDI), repair, trimming, marking, skiving and other processes. The majority of these processes ar...

Silica nanoparticles (SNPs) are widely used all around the world and it is necessary to evaluate appropriate risk management measures. An initial step in this process is to assess worker exposures in their current situation. The objective of this study was to compare concentrations and morphologic characteristics of fumed (FS) and sol-gel silica nanoparticles (SS) in two manufacturing facilitie...
