Torsional behavior of strengthened reinforced concrete beams on two sides by CFRP using EBR Techniques
Get PDFRetrofitting existing buildings or increasing the strength of new buildings has become a major issue in the world today to meet the new requirements. Many studies have sought new techniques to renovate old concrete structures. This paper presents four large scale RC box beams with hollow cross-sections measuring 400 mm x 400 mm and 3,000 mm in length that were tested under torsion; two beams were used as a control specimen whereas, the remaining two beams were partially strengthened for torsion on two sides by EBR-CFRP strips. The effeteness of the number of the layer have been discussed. The relationships between torsional moment and twisted angle, and the failure modes of the beam specimens are investigated. The ultimate torque capacity of beam specimens strengthened by EBR has resulted in improvements in the torque capacity of beams. Specifically, the enhancements were 15% when using one layer of CFRP while when using two layers of CFRP was 29%
Development of a Technique for Generating Unique Land Use Maps Using Remote Sensing Information
Get PDFLand use maps play a crucial role in environmental management, natural resource conservation, and urban planning. Remote sensing technology has emerged as a powerful tool for mapping land use, with high accuracy and low cost. This article presents a new method for creating special land use maps using remote sensing data. The method involves the integration of multiple remote sensing datasets, such as satellite images, aerial photographs, LiDAR data and the application of machine learning algorithms, such as Random Forest and Support Vector Machine. The result is a comprehensive and accurate land use map that can be used for a wide range of application
Synthesis of selenium-containing alkyl products.
Get PDFWe have studied the alkylation reactions of 2-selenoxo-6-methylpyrimidin-4-one with higher C4 -C9 alkyl halides. It was shown that the reaction proceeds mainly by the N3 and O4 reaction centers. We proved this by physicochemical method of analysis (IR, PMR, Mass

Processing of dairy products and research on the composition of probiotic fermented drinks based on acid whey
Get PDFWhey is a very useful product. The amount of whey created depends on the amount of cheese production, as well as the fertility depending on the type of milk, and about 9 L of whey is obtained for every 1 kg of cheese produced. The main problem lies in the high organic load, mainly due to the high content of lactose, but also the appearance of proteins that are difficult to biodegrade. More precisely, the chemical oxygen demand (COD) of cheese whey can vary from 50,000 to 80,000 mg / l, while the biochemical oxygen demand (BOD) ranges from 40,000 to 60,000 mg / l . The rapid consumption of oxygen in the soil as a result of the breakdown of proteins and sugars present in whey, in accordance with the large volume generated, presents the problem of large amounts of elimination. In this context, the production of lactic acid, ethanol, microbial lipids, microbial biomass, single-cell protein, Poly-hydroxyalkanoates, enzymes and endo-polysaccharide
Significance And Classification of Mineral Fertilizers
Get PDFThere is a strong raw material base in our country, which is able to entirely providing the demands of economy in mineral resources. The large reserves of raw materials allowed operating the leading enterprises of the chemical industry such as Almalyk “Ammofos-Maxam” JSC, “MaxamChirchik” JSC, “Ferganaazot” JSC, “Navoiyazot” JSC, “Tashkent Paint Factory” JV, Dehkanabad potassium fertilizers plant” UE, “Kungrad soda plant” UE, “Shurtan gas chemical complex” LLC, “Kungrad sodium sulfate” JV and a number of other chemical enterprises. Currently, large chemical enterprises operate in Almalyk, Chirchik, Fergana, Kokand, Navoi, Shurtan, Dehkanabad and other regions of the country. Agricultural crops area cover about 13% of the Earth surface. It is impossible to expand the area under crops. Nevertheless, the population of our planet is constantly growing, and it is necessary to further increase productivity to provide them with food. One of the most important ways of this is using mineral fertilizers. Fertilizer is a substance designed to improve plant nutrition and increase soil fertility
Enterprise Architecture Tools Assessment for Smart Cities Governance using Fuzzy Logic Techniques
Get PDFThis paper considers the “smart cities” phenomena as the digital transformation alternative for city governance similar to the digital transformation of enterprises. Therefore, in this paper, we propose to use the Enterprise Architecture (EA) methodology and relevant information systems by considering the city as a large organization. Suggested assessment procedure of government-specific EA tools uses customer experience ratings processed with fuzzy logic techniques
