The tobacco industry is an important contributor to realizing the carbon reduction goal. Less attention paid emissions of industry. production system generally a sink, where sequestration by photosynthesis in planting and soil are sufficient offset system. This work proposed integrated framework life-cycle assessment (LCA) Source-Sink Model determine optimal allocation sources sinks with object...

The efficient operation of existing plants in the process industry requires their analysis through simulation together with power and heat integration by retrofitting. Pinch Analysis (PA) is a classical procedure to achieve this goal. Yet, a further integration can be obtained reducing the entropy generated in the chemical processes. Ammonia, important as raw material in many process industries...

An adsorption refrigeration system can be driven by low grade heat and uses natural refrigerant with the advantage of reducing greenhouse gases emission. However, one weaknesses is its efficiency more importantly high cost. The recovery internal waste becomes therefore very important in order to improve coefficient performance (COP). Analysis based on pinch technology helpful optimal operation....

The presence of a very small amount of high molecular weight polymer significantly delays the pinch-off singularity of a drop of water falling from a faucet and leads to the formation of a long-lived cylindrical filament. In this Letter, we present experiments, numerical simulations, and theory which examines the pinch-off process in the presence of polymers. The numerical simulations are found...

Valves are important components in controlling the amount of fluid going to devices. One these types is butterfly valve (BFV) that adjusts flow by rotating disk means its shafts which usually located middle flow. Despite common usage various applications, BFV known cause a high-pressure drop. Conversely, pinch another type control device uses pinching mechanism open and close inner tube at diff...

The object of the current study was to determine whether static contraction of proximal musculature has an effect on the blood flow more distally in the upper extremity. Static contractions of muscles in the neck shoulder region at three levels (relaxed, shoulders elevated and shoulders elevated loaded with 4.95 kg each) were combined with intermittent pinch forces at 0, 10 and 25% of the maxim...
