The investigation of light-ion induced direct reactions in inverse kinematics, using stored and cooled radioactive beams, interacting with internal H, He, etc. gas-jet targets, bears a large potential for nuclear structure and astrophysics studies on exotic nuclei. In particular, this technique enables, as compared to investigations at external targets, high resolution measurements down to very...

Sulfur recirculation is a new technology for reducing boiler corrosion and dioxin formation. It was demonstrated in full-scale tests at a Waste to Energy plant in Göteborg (Sweden) during nearly two months of operation. Sulfur was recirculated as sulfuric acid from the flue gas cleaning back to the boiler, thus creating a sulfur loop. The new technology was evaluated by extensive measurement ca...

Chronic neurodegenerative processes have been identified in the rat forebrain after prolonged survival following hyperthermia (HT) initiated a few hours after transient global ischemia. Since transient global ischemia and ischemic penumbra share pathophysiological similarities, this study addressed the effects of HT induced after recirculation of focal brain ischemia on infarct size during long...

A model for heat-recirculating micro combustor is developed. It investigates the structure of laminar, one-dimensional and steady state flame propagation in uniformly premixed wood particles with considering the effects of heat recirculation caused by configuration of micro combustor. The flame structure is divided into three regions: a preheat-devolatilization zone where the rate of the gas-ph...

The overall scientific objective of the proposed effort is to improve our understanding of the propagation and mass transport of internal solitary waves (ISW), particularly mode-2 ISW, and their significance for coastal ocean processes. In recent years numerous observations of mode-2 ISW have been reported so that it appears that such waveforms may be more prevalent than previously thought. Lar...

plastic recycling is the process of recovering scrap or waste plastics and reprocessing thematerial into useful products that sometimes differ completely in form from their original state. an importantissue in plastic recovery and recycling is that plastic waste usually contains a variety of plastics that differ intheir physical and chemical properties. separation of recovered plastics into dis...

In the modern world, problem of environmental pollution with various toxic emissions is growing more and
 more. Exhaust or exhaust gases internal combustion engines are one those man-made factors. All countries
 impose restrictions on concentration hazardous substances, for example: Euro - cars, Tier and Stage
 heavy equipment MARPOL-73/78, which regulates from maritime transport...

Three kinds of fractal solutions of model of chemical reactors are presented. The first kind concerns the structure of Feigenbaum_s diagram on the limit of chaos. The second kind and the third one concern the effect of initial conditions on the dynamic solutions of models. In the course of computations two types of recirculation were considered, viz. the recirculation of mass (return of a part ...
