Article
В статье рассмотрен метод анализа природных вод на содержание тяжелых металлов. Анализы были проведены в аналитической лаборатории Горно-металлургического института Таджикистана, которая оснащена современным атомно-абсорбционным спектрометром AAnalyst 800. Современные атомно-абсорбционные спектрометры с возможностью проводить анализы двумя методами...

The shield tunnel is a common solution for natural gas pipelines crossing rivers. Consequently, the development of natural gas tunnel filling materials with excellent performance is crucial to the safe operation and maintenance of pipelines. The foam concrete offers a reasonable solution. Nevertheless, since its inherent compressive strength decrea...

In this paper, the mechanical properties of perforated steel plate reinforced concrete were studied. Through the compression test of the specimen, the failure mode, the compressive ultimate bearing capacity, and the stress–strain curve of the specimen were obtained. The results show that the compressive strength of perforated steel plate reinforced...

In the foamed-concrete-backfilled-gas-pipeline project, the fluidity of foamed concrete has a great impact on the construction quality. This research studied the fluidity of foamed concrete through laboratory tests. By changing the water–cement ratio, admixtures, additives, foaming-agent content and other test parameters, foamed concrete with diffe...

This paper proposes a new form of composite beam: a multi-cavity steel-concrete composite beam. This composite beam uses internal perforated steel plate to connect the concrete with the steel structure, and shear connectors are no longer required, which is more suitable for industrial production. The mechanical properties of a multi-cavity steel-co...

Foamed concrete is mostly used for backfilling of long-distance tunnels and compressive strength is an important technical index to control the quality of foamed concrete. The influence factors on compressive strength of low-density foamed concrete were obtained by the single factor test method based on the targeted dry density and compressive stre...

This is a study on how to reduce shrinkage and improve crack resistance of foamed concrete. By selecting different curing temperatures and humidity, six different curing conditions were analyzed. The shrinkage deformation and maximum crack width of foamed concrete blocks with water–cement ratios of 0.4 and 0.5, under six curing conditions, were mea...

The Syrdarya River is the most important water artery of the Fergana Valley in Central Asia. The quality of its waters largely determines the state of the environment and the health of the population, which live in the Syrdarya river basin. The purpose of the work is to assess the level of river pollution through monthly monitoring of the concentra...

The aim of this study was to investigate how arsenic is bound to soil components to assess the potential leachability and bioavailability, both important factors in evaluating the pollution risks. Soil samples (from populated land in the valley and from the ridge above Death valley, close to former smelting plant) were investigated using the BCR ex...

Project
Water H-II is aimed at developing and expanding the project initiative - CPEA-2011/10002 “Water Harmony - Integration of Education, Research, Innovation and Entrepreneurship” (with the financial support of the Norwegian Center for International Cooperation in Education (SIU) on the basis of an agreement with the Norwegian By the Ministry of Foreign Affairs). Also, the creation of a scientific and pedagogical consortium, including 10 partner universities from Belarus, Kazakhstan, Kyrgyzstan, the Republic of Moldova, Tajikistan, Ukraine and Norway, to harmonize higher education related to water resources, in order to increase its relevance and quality. Improving the quality of education is supported by modern teaching tools, teaching methodologies, pedagogical approaches with flexible learning paths, virtual and physical mobility, blended courses, internships, etc. In addition, attention is paid to ensuring the quality of education, the development of research and innovation potential, which are among the regional priorities.
