Published: July 2023

Abstract
The essential part of any shading device is to intercept the solar radiation in such a manner that it allows enough daylight inside the building, while at the same time the indoor thermal comfort is upheld for all the seasons. Earlier studies proved that in comparison with internal shading devices, the external ones minimize the internal heat gain in an effective manner by blocking the radiation, before it reaches the fenestration glazing. However, fixed external shades are incapable of balancing the varying requirements of light and heat for different climatic conditions. Mainly, summer and winter in the composite climate demands adaptive shading solutions as per the changing season. The current study is an attempt to evolve appropriate external adaptive louver shades and recommend louver angles for different months, for a single space of a typical apartment building in Delhi NCR region. The recommended angles allow the occupants to make informed decisions by manually adjusting the louvers to improve the indoor environment. This study utilized ladybug and honeybee plugins for the purpose of simulation. The results show that the monthly adjustments of external adaptive shades enhance the indoor environment and save energy. The study developed, analysed and compared two different types of external adaptive louver shading systems such as EALS (External Adaptive Louver Screen) and EALA (External Adaptive Louver Awning) for better indoor environment and energy saving for west orientation.

Abstract
Noise has become one of the most critical problems to address in contemporary cities, and the awareness of the consequences of noise pollution has been increasing lately. Road traffic noise exposure is considered a serious environmental health hazard, as excessive exposure to noise increases cardiovascular diseases and anxiety. People spend most of their time in residences where they become tolerant of noisy environments and are unaware of the effects caused by them. Indoor acoustic comfort in residences is one of the unexplored parts of Indoor environmental quality (IEQ). Achieving sufficient acoustic comfort is of the main priorities in achieving IEQ. Facades are the constructive elements which act as a barrier between outdoor and indoor sound transmission. The main aim of this research is to optimize the characteristics of different elements of the façade of a residential building to enhance indoor acoustic comfort. A case study residence is chosen at Guindy, Chennai, to study the outdoor sound pattern and the corresponding indoor sound level. The outdoor sound level is measured continuously at 1 m from the facade. The indoor sound level is measured at the centre of each room at regular time intervals. Field measurements were conducted in the 2 BHK apartment, and the results were processed to assign each room's acoustic class and determine the residence’s Key Performance Index in terms of acoustic comfort. The results of this research will be optimized in the upcoming research phase using Pachyderm (Grasshopper plugin) to find the best design parameters for the facade to achieve good acoustic comfort in a residence.
Traditional Building Knowledge Systems - A Path to Sustainability

Published: July 2023

Abstract
In architecture and planning domain, sustainability has been considered as a core strategy for over three decades now. The modern era of globalisation, led to homogenisation in architecture, thus widening the gap between modern and Traditional Building Knowledge systems (TBKS) worldwide. This gap is widening at an alarming speed and alienating the architectural concepts from the context and its people, by ignoring the sustainability aspects. The TBKS has evolved in line with the environmental, cultural, technological, economic, and historical context within which it exists. The current study provides an overview of the concepts involved in sustainability and TBKS and how TBKS is addressed in the international forums and UN reports, and ancient treatises that formed the basis of TBKS in the Indian context. The four pillars of sustainability i.e., environmental, social, economic, and cultural dimensions were considered as the parameters to measure how far the sustainability has been achieved in the built environment. From the extensive review of literature, a set of design indicators was identified for the TBKS. Further, its applicability was also analysed based on the case examples. The current study reveals that such indicators, mentioned in the TBKS, are context-specific in nature. Hence, it helps in achieving sustainability at the building level. The paper concludes by identifying the co-relation between TBKS and sustainability and calls for more studies upon using the Traditional Building Knowledge Systems as a potential tool to achieve sustainability.

Abstract
This article analyzes the materials concerning the study of the dynamics of the flow and the channel process in urban areas in the delta of the Amudarya river. In this section, the regularities of the negative impact of anthropogenic factors on the dynamics of the river flow and the course of channel processes were studied. The scale of the impact of urbanization factors that significantly change the course of the channel process is determined and the structural levels of channel forms are assessed. The most cost-effective method for cleaning river beds from polluted bottom sediments by specially created volley water discharges from the upper pool of existing hydroelectric facilities is proposed. Changes in the channel processes in the delta of the Amudarya river under the influence of annually recurring catastrophic low water and strong wind erosion are shown. The time scales at various structural levels of the channel process have been refined. The article used general scientific research methods based on the analysis and generalization of natural and experimental materials.

Abstract
The article presents statistical data on the dynamics of the forest fund of the Orenburg region. The study of changes in the state of the forest fund, its dynamics is the main means of forestry production, which is of great ecological importance with the possibility of developing rational forms of management in them. The natural and climatic conditions of the Southern Cis-Urals have a direct impact on the formation of forest ecosystems, which are the ecological framework of steppe landscapes. The study showed that during the analyzed period (2016-2019) the area of young stands decreased, and the stable growth of areas of mature and overmature plantations continues. The change in the age structure of the forest fund during the study period is relatively stable, but does not correspond to the optimal “normal forest” model. The factors that contribute to the reduction of the production potential of the forests of the Southern Cis-Urals under the conditions of unfavorable natural and climatic changes have been identified. One of the vectors for the conservation of existing forest resources is to maintain a balance between retired and restored forest areas, the main condition for the stabilization of which is the implementation of comprehensive reforestation and monitoring observations of forest pest and disease outbreaks. The reduction in the area of arrival of forest plantations, in the near future, will change the direction of stabilization of the age structure of forests.

Abstract
The studies were carried out in a large fruit-growing farm in Central Russia “Agrofirm named after 15 years of October” in the Lebedyansky district of the Lipetsk region. The farm is switching to intensive horticulture using new varieties of apple trees on low-growing rootstocks. The article analyzed the results of a study of a comprehensive assessment of apple varieties with the necessary technological parameters for the production of products that meet domestic and international standards. We studied the main components of productivity and marketability of four varieties of apple trees on low-growing rootstocks: Ligol, Honey Crunch, Berkutovskoe and Spartan. It was found that all varieties are productive and have high marketability. But the most productive variety was Ligol -75 t/ha, which exceeded Spartan by 24 t/ha, Berkutovskoe - by 39 t/ha and Honey Crunch - by 48 t/ha. It was established that the commercial qualities of fruits depended on the characteristics of the variety, changing from the place of growth and the weather conditions of the year. By the sum of sugars, the best variety of apples was determined - this is Spartan, it had the most sugars (11.9%), the excess over the Ligol variety was 1.0%, Honey Crunch - 1.3%, Berkutovskoe - 1.6%. It was found that the highest content of ascorbic acid was in apples of the Berkutovskoye variety (15 mg/100 g), somewhat less was contained in the fruits of Honey Crunch - 14.5 mg/100 g. The minimum amount (8.8 mg/100 g) of ascorbic acid was in Spartan apples. It was established that with an average value of the sugar-acid coefficient of 13.8, the diversity limits for the studied varieties varied from 12.8 (Ligol) to 14.3 (Honey Crunch and Spartan). It was suggested that two varieties of honey crunch and Spartan are closest to the optimal values for this indicator.

Authors: Nekrich A S 
Published: July 2023

Abstract
The article outlines the location, scales, and intensity of the current ecosystems transformation due to operation of the agro-industrial complex industries in Bryansk Oblast of the Russian Federation. By means of official statistic data and space images gathered from open sources, the key factors determining the environmental condition of agricultural landscapes are identified. For each agricultural landscape’s units, a detailed description is given. Analysis of the current environmental situation within these units is also conducted. It was determined that over the last 12 years, the severe level of ecosystems transformation has been forming in the central and eastern parts of agricultural lands. The significant level of ecosystems transformation is observed in the north, as well as in the eastern and southwestern parts. The moderate level of ecosystems transformation is mostly common on the western part and is located in the central and eastern parts of agricultural lands. The minor level of ecosystems transformation is typical for the south-central and for the north-central parts of agricultural lands. The study shows that the spatial differentiation of the levels of ecosystems transformation in Bryansk Oblast is strongly determined by environmental conditions, the structure of natural landscapes, and depends on the specifics of agriculture.

Abstract
The concentration of 50 chemical elements in the leaves of Populus suaveolens Fischer and Betula pendula Roth growing in tailings dumps and dumps of gold deposits in Eastern Transbaikalia (Baley) was studied. It was found that the highest concentration of most elements was in the leaves of plants growing at the ZIF-2 tailings dump, and the lowest was on the sands of the thorium tailings dump and sand–pebble soil at the dredge gold mining site. Populus suaveolens differed from Betula pendula by a higher concentration of most chemical elements. A feature of the elemental composition of birch was a significant concentration of Mn and Ba in relation to poplar. The concentration of a number of chemical elements significantly exceeded the clark of terrestrial plants, as well as the maximum permissible levels of concentration of elements established for feed and medicinal plant raw materials.

Authors: Gorelkina E I , Mugisho J B , Kouadio K S 
Published: July 2023

Abstract
This article discusses reservoir pressure maintenance methods: flooding and SWAG technology. The accumulated experience of waterflooding technology introduction described in literature sources is analyzed. Identified such disadvantages of waterflooding as reservoir watering due to significantly low viscosity compared to the viscosity of reservoir oils and low oil recovery factor. A method for detecting and preventing the instability of the front of displacement of residual reserves by injected water is indicated. Particular attention is paid to the innovative method of reservoir stimulation, which consists in the generation of carbon dioxide in reservoir conditions. The essence of the technology, method of implementation, advantages compared to gas injection through injection wells are described. Water-gas methods are investigated. The advantage of SWAG technology with the use of pump-ejector systems in comparison with other modifications is proved and the results of the latest research are presented, which cover data on the characteristics of pump-ejector systems, the topical issue of the technology for obtaining water-gas mixtures and the processes of interaction of gas bubbles when pumping mixtures through wells into the reservoir, as well as ways to implement the technology, taking into account the geological and field conditions of potential targets for implementation. This analysis will allow you to correctly choose the method of stimulation of the reservoir and operate the facilities as efficiently as possible. It should be noted that the considered gas and water-gas methods involve the injection of carbon dioxide, associated, exhaust, flue gases into the reservoir, which makes these technologies the most attractive from an environmental point of view.

Published: July 2023

Abstract
The paper presents a simplified thermal model that allows estimating heat losses taking into account the main parameters: the surface of the greenhouse - a transparent fence, the bottom of the greenhouse - soil and the ratio of the design of greenhouses. A simplified thermal diagram of the greenhouse heat transfer has been compiled and, on the basis of the simplified thermal diagram, heat losses through the transparent enclosure, through the bottom, soil and structural ratios have been determined by calculation. Calculations show that with total solar radiation, 620 W/m2, heat loss through the surface of a transparent fence is 508 W/m2, in percentage terms it is 82%. At the same time, through the bottom (ground) 58 W / m2, in percentage terms they are 9%, the total heat loss is 566 W / m2, in percentage terms they are 91%. To reduce heat loss through the transparent enclosure, it is recommended to use more innovative materials, such as ceramic film with improved thermal insulation properties or low iron glass, extra clear glass, double-layer transparent enclosure, and it is also recommended to enclose one side of the greenhouse with a thermal insulation wall. According to calculations, in order to reduce heat losses through the bottom of the greenhouse, we recommend making a special deepening in the soil, since at large soil depths, a slow spread of soil temperature is observed, which will also lead to the least heat loss. To reduce heat losses through the bottom of the greenhouse, we recommend using thermal energy accumulators in the ground. Estimation of heat losses makes it possible to determine the required amount of heat loss through the surface and bottom of the greenhouse and, based on these calculations, carry out research work to reduce them.

Published: July 2023

Abstract
The research of the Torey lakes regon, Ulzda-Torey internal drainage area has established that the manifestation of the general global warming trend in the recent decades had been the moderate regional temperature shifts which induce significant changes in the hydrological states and lead to shifts of the hydrological cycle in general. It has been verified that in the discussed area the ground air temperature indications had shifted from the average negative to the average positive. In the period of 1938-1989 the air temperature had a negative value with the average of -1.0°C in 52 years. Starting from 1989 the average annual temperature indications had turned positive, namely +0.4°C in 32 years. A comparative research of the area for the 1938-2021 period has indicated that the regional air temperature rise by 2.2°C combined with the waning annual amount of atmospheric precipitation (with the average of 21%) leads to a sharp decrease of the average annual river flow (by 16%) and even down to none.
