Some vegetables and fruits grown in Azerbaijan are indispensable for the\nproduction of a wide range of food, juice and confectionery products, because of their\nchemical composition and biochemical properties.One of the factors hindering their widespread use in the food industry is the insufficient study of their functional and probiotic properties in the mentioned technological areas, and the labor intensity of the preparatory work.\nMechanical properties of the carrot varieties Nant 4 and Shantane 2461intended for\nobtaining juice have been studied. Tension limit and power consumption for squeezing\nand cutting of the carrot were determined. The structure of the carrot pulp was\nestablished. The highest juice output was observed in the Nant variety. To increase the\njuice output from the pulp, maceration was applied and parameters of the enzymatic\nhydrolysis were determined. Complex two-stagemechanical grinding allowed the\nproduction of juice with high organoleptic properties. Antioxidant activity was determined before and after themaceration of carrots. A mode and parameters of the juice\nproducing technology were corrected during the research.\nReady-made pulpy juice samples were tasted and evaluated. The recommended\nrecipe for carrot juice has been developed.
Methanesulfonic acid (MSA) was used as a green acid for the leaching of two valuable elements, copper and uranium, from poly-metallic siltstone ore, Sinai, Egypt. Six parameters were investigated namely: initial acid concentration, stirring speed, particle size, liquid/solid mass ratio, and temperature. It is found that the MSA is effective as a leaching agent for the recovery of copper and uranium. The rate of dissolution of copper is always higher than that of uranium. The results of the kinetics of the dissolution process were analyzed on the basis of the Shrinking Core Model, SCM. It is found that for uranium the leaching kinetic is controlled by the diffusion via the solid layers of insoluble and/or slow soluble materials. The kinetic leaching equation representing uranium kinetics indicated that liquid to solid ratio plays a significant role in uranium leaching compared to the other parameters. In the case of the dissolution of copper, the kinetic equation obtained from the analysis of the experimental data displayed that the dissolution kinetics is affected by the studied parameters in the order of stirring speed ≈ L/S ratio > initial MSA concentration >> particle size. The kinetic model of copper dissolution is based on the assumption that the rate of copper leaching is driven by the combination of the diffusion through the boundary solution layer and the surface chemical reaction.
ABSTRACT\nBackground: Cleome droserifolia plant or Samwah of South Sinai is usually used in folk medicine for diabetes treatment. Diabetes mellitus disease is a chronic disease caused by a deficiency in secretion of insulin and by reduced responsiveness of the tissues to the secreted insulin. The present study aims to illustrate the effectiveness of Cleome droserifolia plant aqueous extract on the ileum of diabetic rats. Material and Methods: thirty -2 adult male rats were divided into four equal groups as follow, control group, plant treated group, diabetic group and diabetic plus plant treatment group that was given orally (100 mg/kg b.wt./day) for 30 days. Small samples of the ileum tissues were collected for histochemical and histopathological studies at the end of the experiment. Results: Ileal tissues of diabetic rats revealed numerous lymphocytic infiltrations, cytoplasmic vacuolization, pyknotic nuclei, detached epithelial layer and eroded villi tips. While diabetic and plant-treated rats showed minimized degenerative changes compared to diabetic rats but densely stained nuclei of the lining epithelial cells and slight erosion of some villi were still detected. Conclusion: It could be concluded that Cleome droserifolia plant extract treatment exerts a relatively therapeutic protective effect in diabetes by decreasing tissue damage of the ileum which may be attributed to its antioxidative, anti-inflammatory and antidiabetic properties.
This research aims to measure the effects of goods and services production on the Carbon dioxide (CO2) production. The research is supported by a theoretical and methodological proposal of a production function that considers two outputs that allows to assess and to demonstrate that emissions tend to reduce with the economic growth. This research uses a panel data for North American region. Outcomes highlight that, after twenty years of NAFTA agreement signature, with the economic growth of the region CO2 emissions have reduced. This outcome is consistent with the ones found in studies carried out for those European countries, members of the Organization for Economic Co-operation and Development (OECD).
