Relevance. By the beginning of the XXI century, the growth of cities, population concentration and the revival of industrial production led to an intense technogenic pressure on the underground hydrosphere. In ecological and hydrogeological studies, it becomes necessary to conduct monitoring observations of groundwater based on GIS technologies. Purpose of the work: study of the hydrogeochemical characteristics of underground waters of the aquiferous lower Kazanian carbonate-terrigenous complex to provide Kazan with high-quality drinking water from protected underground sources. Research methodology. Hydrochemical data from geological reports and archival materials for the period from 1960 years to 2019 years were used. Methods of mathematical statistics (basic, cluster and factor analyzes) made it possible to differentiate into natural and man-made components. Geographic information modeling using the “ArcGisMap” package showed the spatial variability of the main components in the waters of the Neogene complex at the turn of the 20th and 21st centuries. Conclusion. The hydrochemical parameters of the aquiferous lower Kazanian complex are assessed as favorable, since practically all the main components do not exceed the MPC values for drinking water.

Radionuclides (uranium, thorium, radium, radon gas etc.) are found naturally in air, water, soil and rock. Everyday, we ingest and inhale these radionuclides through the air we breathe and through food and water we take. Out of the internal exposure via ingestion of radionuclides, water contributes the major portion. The natural radioactivity of water is due to the activity transfer from bed rock and soils. In our surveys carried out in the past few years, we have observed high concentrations of uranium and total dissolved solids (TDS) in drinking waters of some southern parts of Punjab State exceeding the safe limits recommended by national and international agencies. The main drinking water source is the underground water procured from different depths. Due to the highly saline taste, disorders in their digestive systems and other ailments, people are installing reverse osmosis (RO) systems in their houses. Some RO systems have been installed on commercial basis. The state government is also in the process of installing community RO systems at the village level. As high values of uranium are also undesired and may pose health hazards due to radioactivity and toxicity of uranium, we have conducted a survey in the field to study the performance of various RO systems for removal of uranium and TDS. Water samples from about forty RO systems from Faridkot, Mansa, Bathinda and Amritsar districts of Punjab State were collected and analyzed. Our results show that some RO systems are able to remove more than 99% of uranium in the underground waters used for drinking purposes. TDS values are also reduced considerably to the desired levels. So RO systems can be used to avoid the risk of unduly health problems posed by high concentrations of uranium and TDS in drinking water.

Building-information-modeling for cultural heritage (HBIM), which is established using surveying data, can be used to conserve architectural heritage. The development of an HBIM model for ancient wooden architecture (AWA) structures requires interdisciplinary integration. A parametric model for the main components that intelligently integrates the historical knowledge, as well as an intelligent modeling method for these components, are two critical issues required to bridge the existing gap and improve the application of HBIM. Taking an AWA structure constructed during the Liao and Song Dynasties as an example, the parametric model for the typical components, with emphasis on commonality and characteristics, were first proposed. Subsequently, an intelligent automated modeling method was developed and programmed using Dynamo, which can intelligently identify the component type and determine the invisible dimensions. A complicated dou-gong was successfully established with surveying data using the proposed method within five minutes, thereby validating the reliability and efficiency of this method. Furthermore, the proposed method was used to establish the HBIM model of Yingxian Wood Pagoda, which is the oldest and tallest AWA structure in China with a height of 65.88 m. The research findings will provide an essential reference for the conservation of wooden architectural heritage structures.

The problem of arsenic in drinking water, which causes a violation of human health, is revealed. The main ways of arsenic ingress from the lithosphere into drinking water are shown. In the earth's crust, arsenic is contained in rocky rocks, from where it under the influence of weathering processes passes into sedimentary rocks, alluvium and silts. When underground water passes through a section of the earth's crust containing arsenic in the form of its minerals, the water is saturated with arsenic. Chemical reactions of arsenic transition to easily soluble forms and its main compounds in natural waters are presented. The mechanism of arsenic migration in natural surface and underground waters is explained. In Bangladesh, about 60 million people use arsenic-contaminated groundwater as drinking water and are therefore at risk of poisoning. Detailed map of the world on the risk of arsenic contamination of natural fresh water. It is shown that in Kazakhstan there are numerous geogenic deposits and ore occurrences of arsenic, which naturally infect groundwater. The West Kalba ore belt, which is about 800 km long and 80-100 km wide, has been identified only within Eastern Kazakhstan, and its ore objects are represented by gold-arsenopyrite (with an arsenic content of up to 2-5 %) ores. In addition, Kazakhstan has a significant technogenic component of arsenic water pollution due to the influence of the mining industry: only in the dumps of the Ust-Kamenogorsk metallurgical plant, more than 300 thousand tons of arsenic mineral products have already accumulated, with an annual increase of 11 thousand tons. The method of disposal of such waste, as well as localization of arsenic from underground polluted waters on technogenic geochemical barriers, is described.

Aquifer Complex

The specificity of the chemical composition of underground waters of the Quaternary aquifer complex of the Azov sea catchment basin, which dominates the flow volume, is considered. Using deterministic models, the volumes of runoff of the main ions, common iron, and methane are calculated. The predominant ones are sulphate, chloride-sulphate or sulphate-chloride, less often bicarbonate and chloride waters, usually of a sodium or calcium cationic composition. The average annual volume of underground water flow in the Quaternary complex is about 0.024 km3/year (66,300 m3/day). The average annual value of underground ion runoff is ~387,000 t/year, with 47.2% of this value being accounted for by sulfate ions. The average annual underground runoff of total iron and methane is ~0.968 t/year and ~0.037 t/year, respectively. The dominant contribution (over 98%) to the volume of underground runoff of the main ions, common iron and methane is made by their runoff from the Northern sections of the sea catchment basin, which is mainly due to the distribution of the module of underground water flow.

The Relationship

This study wanted to look at the relationship and influence of social capital on cognitive function in schizophrenic patients. Social capital is a concept that arises from the results of interaction in society with a long process and is believed to be one of the main components in driving togetherness, mobility of ideas, mutual trust and mutual benefit to achieve mutual progress. Interactions that form networks in togetherness in social capital contain norms, values and mutual understanding that facilitate cooperation in a group. Social capital is generally associated with health and is considered an important etiology in schizophrenia where in the early stages of schizophrenia there are significant cognitive symptoms making it very difficult for people with the disorder to work, study or work in social life. This research method uses the design of latitude cut study, conducted in dr. hospital. soeselo and using MMSE instruments. The results of the study found a link between social capital and cognitive symptoms in schizophrenic patients where in individuals with good social capital was shown to better adjust to cognitive function. Conclusions on individuals with good social capital can adjust better because individuals have had better coping, perception and adjustment about themselves and their environment, individuals already have the ability to maintain their communication and interaction in public life.

Abstract Drinking water, as one of the main components of the habitat, determines human health and quality of life. In the past few decades, almost all water sources, both surface and underground, have been subject to intensive anthropogenic and technogenic impact. Lake Gusinoye, which is the main source of drinking water supply to adjacent settlements, is experiencing significant anthropogenic pressure. Based on the results of hydrochemical studies, the toxic effect of heavy metals on the population health, resulting from the consumption of drinking water of the centralised water supply from Gusinoye Lake, was considered. The results of a quantitative assessment of public health hazards showed that the risk of non-carcinogenic (toxic) effects is high in the territory of the Gusinoozersk industrial hub.
