selection and introduction of superior genotypes from native populations is one of the most common improving methods for fruit trees in the world. iran as a very important origin of apricot has a huge diversity of varieties, so a rich collection of local and imported genotypes of apricot was induced in sahand horticultural research station from 1971. nasiri 90 and other four superior varieties ...
This paper presents results of research on the use of plasma technology for printed circuit boards (PCB) processing for metals and energy recovery. In the Industrial Research Institute for Automation and Measurements, a test stand was built allowing experiments on plasma process with throughput of 800 kg per day. Brief examination of PCB waste was carried out, focusing on identification of its ...
Heat exchanger performance degrades rapidly during operation due to formation of deposits on heat transfer surfaces which ultimately reduces service life of the equipment. Due to scaling, product deteriorates which causes lack of proper heating. Chemistry of milk scaling is qualitatively understood and the mathematical models for fouling at low temperatures have been produced but the behavior o...
