A two-machine flow shop scheduling problem with rejection is considered in this paper. The objective is to minimize the sum of makespan of accepted operations and total penalty of rejected operations. Each job has two operations that could be rejected, respectively. Operations on the first...

Bi0.95La0.05FeO3(BLFOx=0.05) film was fabricated on indium tin oxide/glass substrate using a metal organic decomposition method. No secondary phase can be observed in the well crystallized and predominantly (110)-oriented BLFOx=0.05 film. Well-saturated P - E hysteresis loops with the remanent...

Using bilateral migration flow data from the 2010 population census of Nepal, this paper provides evidence on the importance of public infrastructure and services in determining migration flows. The empirical specification, based on a generalized nested logit model, corrects for the non-random...

Modern subsoiling technology is a little ploughing measure in dry land protective farming technology system. The subsoiler can scarify soil, deepen the arable layer, break the plough layer, improve the soil permeability, increase soil infiltration speed and amount, and create an arable layer...

Inequality in South Asia appears to be moderate when looking at standard indicators such as the Gini index, which are based on consumption expenditures per capita. But other pieces of evidence reveal enormous gaps, from extravagant wealth at one end to lack of access to the most basic services...

This study addresses the role of climate variability in the livelihoods of agricultural communities in Ningxia, Northwest China. Data sources comprise meteorological observations and official reports, complemented by questionnaires and focus group discussions designed around a livelihoods...

Northern Tibet is the headstream region for the Yangtze, Salween River, Mekong River, and numerous other inflowing rivers and high mountain lakes. Sustaining the environmental conditions in the region is of vital importance for Tibet and the whole of China. The alpine grassland ecosystem in...

In 2011, the National Oceanic and Atmospheric Administration (NOAA) reported that the coastal population of the US that lives within 50 miles of the shoreline exceeded 50 % for the first time in history in spite of a high level of exposure to hurricanes and related flooding. Hurricane Andrew...

Based on a system dynamics (SD) model of long-term cost-effectiveness of power pole maintenance over 50 years, the influence of factors that affect cost-effectiveness was examined. Taking a typical region subjected to hurricanes (i.e., Miami-Dade County, USA) as a case, the SD model was...
