It is hypothesized that quantitative overload impacts psycho-physiological attributes of data-entry operators, although previous research has focused primarily on different aspects of VDT work, such as working time and environment, work station, keyboards and so forth. The objective of this study was to examine the influence on psycho-physiological responses of time pressure, task demand and th...

We introduce an effective method to actively induce droplet generation using negative pressure. Droplets can be generated on demand using a series of periodic negative pressure pulses. Fluidic network models were developed using the analogy to electric networks to relate the pressure conditions for different flow regimes. Experimental results show that the droplet volume is correlated to the pr...

Goals for the perioperative management of patients with coronary artery disease include: * Prevent increases in sympathetic nervous system activity: reduce anxiety preoperatively; prevent stress response and release of catecholamines by appropriate use of opioids or volatile anesthetics and beta-adrenoceptor antagonists; beta-blocker therapy should be initiated before and continued during and a...

The study aims to estimate an international reserves demand model for China using economic growth, propensity to import, real effective exchange rate and trade openness variables for quarterly period spanning from 1985Q1 to 2014Q4.The bounds testing technique to cointegration is used to test for a long run relationship, while the autoregressive distributed lag approach is used to estimate short...

this study deals with a two-level supply chain consisting of one manufacturer and one retailer. we consider an integrated production inventory system where the manufacturer processes raw materials in order to deliver finished product with imperfect quality to the retailer, where number of defective product has a uniform distribution. the retailer receives product and conducts a 100% inspection....
