The article describes the development of a methodology for radon pollution studies based on algorithms that take into account the influence of constant mountain-valley winds. The solved problem of the study of radon emanations arising from the stress-strain state of rocks is an important step in the study of man-made bulk arrays on the environment and the assessment of radiation safety. Decommissioned tailings dumps eventually dry up and turn into hardening man-made bulk arrays, which negatively affect the surrounding ecosystems. The proposed methodology is implemented on the basis of the proposed algorithms for determining the optimal choice of measurement conditions, taking into account the influence of constant mountain-valley winds. As an approbation of the methodology, field studies were carried out, including measurements of the equivalent equilibrium volume activity of radon-222 at various points of the tailings dump. For this purpose, specialized methods and devices were used, which made it possible to determine the concentration of radon in the air and evaluate its emanations from the tailings dump. The data obtained were processed and analyzed using specialized software and algorithmic software, which allows for a detailed analysis and evaluation of the values.

Cellulose is a natural polymer and most abundant organic substance on Earth. Inexhaustible hydroxyl groups on the cellulose surface allow derivatives of cellulose produced. This article discusses the recent progress of cellulose and cellulose derivatives in membrane development for oil/water separation. Functional groups that are available on the cellulose and its derivatives provide modification features to improve membrane wettability. Membranes with super wetting properties possess remarkable self-cleaning abilities which in turn can enhance permeation fluxes and extend membrane lifespan. However, the role of cellulose-based membranes in oily wastewater treatments is still in its early stages. This review article emphasizes on the development and modification of cellulose-based membranes for improvement of wettability, flux and separation efficiency, and the future directions of research.

The most prevalent malignancy among women is breast cancer, which had almost 1.3 million new cases in 2020. It is the second most common cancer in the world, followed by lung cancer. The survival rate would be 99% if the cancerous tumour was limited to the breast. If the cancer migrated to neighbouring lymph nodes, the survival percentage would be 85% and it would drop to 27% if it spread to distant regions. In fact, the most prevalent breast cancer subtype is that caused by excessive estrogen levels. The enhancement of pertinent treatment techniques depends on the estrogen receptors (ER) in both healthy and pathological conditions. There are two primary types of ER, ERα and ERβ, which are each encoded by a different gene. ER status is the most important indicator of breast cancer prediction. To develop novel therapeutics for breast cancer, 30 newly designed benzimidazole compounds targeting the ER were docked. Among them, a compound with a glide score of −9.293 was discovered to be the leading compound. ADME investigations provided additional validation of the docking results. The pyrazole fused benzimidazole nucleus is therefore suggested as a potential pharmacophore for the development of innovative anticancer treatment for breast cancer.

High turbidity is a pollutant that requires coagulants to be removed from treated water and wastewater. This study was conducted to characterize and analyze the potential of myco-coagulant-producing fungus isolated from the moist area of a kitchen. Myco-coagulant production was carried out using solid-state fermentation using coco peat as a substrate. One factor-at-a-time analysis (OFAT) was carried out to assess the capacity of the produced myco-coagulant in various initial turbidities and myco-coagulant doses. The potential of myco-coagulant was tested using turbid synthetic water with different turbidity levels (50, 100, 150, 200, 250 and 300 NTU). The results showed that turbidity removal by the myco-coagulant was influenced by the initial turbidity. The coagulant was less efficient at low turbidity levels, which was approximately 5% for 50 NTU, while the highest was 52% for 300 NTU water. Furthermore, the results demonstrated that myco-coagulant could remove the highest possible turbidities on day 6 with all initial turbidity values studied in this work. Different myco-coagulant doses ranging from 1 to 10% (v/v) were also used to determine the optimum dose for effective flocculation. The highest turbidity removal of 57% could be obtained at an optimum coagulant dose of 4% (v/v). Like any other commercial coagulant, the residual turbidity value increased at a coagulant dose higher than the optimum dose of 4% (v/v).

Grain drying control strategies aim for a rational energy use and a final product with low breakage levels. However, an experimental approach may be prohibitive due to the costs, scale, and theoretical complexity of this operation. The simulation environment is suitable to design equipment’s and plan operations strategies with low cost and high certainty. This work utilized system dynamics modelling to quantify the percentage of product breakage during drying in fluidized bed dryers under recirculation and tempering strategies. A sensitivity analysis of the model’s input parameters including different fractions of recirculation was performed, showing their effects on drying and post-drying product quality. Finally, we present optimizations from different objectives of drying operations. The recirculation strategy worked as an attenuator to the drying rates and combined with tempering strategy reached a minimum breakage level.

Large areas of soil in Iraq are formed up of gypsum soil. As a result, understanding the habits of this soil and its treatment approach is critical, because its current solution is to replace gypsum soil before beginning any building activity. This study used gypsum soil from Tikrit City, which has a gypsum concentration that is around 38%, and the goal of the study is to illustrate the impact of the polymer on the gypsum soil parameters. Simultaneously, researchers are investigating the beneficial effects of polymers on the behavior of gypsum soil. The percentages of the polymer additive (5%, 7.5%, 10%, 12.5%, and 15%) were weight percentages, while the soil tests were chemical, physical, and engineering. When the percentage of additive was increased from 0% to 15%, Soil engineering characteristics enhanced the collapse of the from 5.11 to 1.21, cohesion improved from (28.98 KN/m2) to (51.16 KN/m2), and angles of internal friction decreased from 33.190 to 38.850.

Environmental contamination increased as a result of the extensive use of fossil fuels, large-scale industrialization, and population growth. It has become an urgent need to reduce carbon emissions for environmental sustainability. The revolution in renewable energy may be the best option for lowering carbon emissions. In this research, rice straw was considered as a possible wellspring of bioenergy production. The aim of the study is to determine the best way to use biomass by comprehending its thermal qualities. Several state-of-the-art techniques were used to characterize the rice straws to understand their potential as a solid fuel for clean energy production. Elemental analysis reveals the predominance of carbon and oxygen content while nitrogen and sulfur are minor constituents in the studied rice straws. Fourier transform infrared (FTIR) spectroscopy analysis suggested the presence of cellulosic and ligneous constituents. Pyrolysis is one of the appropriate choices to make esteem expansion and contributes to biomass utilization. The thermogravimetric analysis (TGA) analyses revealed that rice straw pyrolysis has occurred in three distinct stages i.e., dehydration, active pyrolysis, and passive pyrolysis. The differential thermogravimetric graph (DTG) depicts how the temperature peak at the greatest weight loss shifts as the heating rate rises. Based on the characterization and subsequent analysis, it can be concluded that rice straw is a critical biomass and suitable to be used in clean energy production and maintain environmental sustainability.

Biomethanol, a renewable and sustainable alternative to traditional fossil-fuel-derived methanol, has garnered considerable attention as a potential solution to mitigate greenhouse gas emissions and dependence on non-renewable resources. The utilization of biocatalysts in biomethanol production offers a promising avenue to achieve environmentally friendly and economically viable processes. Paper highlights the biocatalytic pathways involved in biomethanol synthesis. Particular emphasis is placed on microbial biocatalysts, such as methanogenic archaea and certain bacteria, which possess the unique capability of converting carbon dioxide and hydrogen into methanol through a series of enzymatic reactions. Additionally, enzyme-based systems derived from various microorganisms and genetically engineered organisms are also discussed as potential biocatalysts for biomethanol synthesis. Paper also delves into the current challenges and limitations faced in harnessing biocatalysts for biomethanol production. These challenges include substrate availability, low conversion rates, enzyme stability, and process scalability. Several strategies to address these issues are highlighted, including metabolic engineering, synthetic biology, and bioprocess optimization techniques. The advantages of utilizing biocatalysts for biomethanol production are outlined. Biocatalytic routes offer the advantage of operating under mild conditions, which reduces energy consumption and minimizes the production of unwanted by-products. Furthermore, the utilization of renewable feedstocks, such as carbon dioxide captured from industrial emissions or waste streams, enhances the sustainability of the process. The final section discusses future prospects and potential research directions in the field of biocatalytic biomethanol production. Advances in biotechnology, omics technologies, and computational modeling are poised to accelerate the discovery and optimization of novel biocatalysts, thereby unlocking the full potential of biomethanol as a sustainable fuel and chemical precursor. The use of biocatalysts for biomethanol production offers an attractive approach to establish a green and circular economy. With ongoing research and technological advancements, the field holds significant promise for reducing carbon emissions and transitioning towards a more sustainable energy landscape. However, to fully realize the potential of biocatalytic biomethanol production, interdisciplinary collaboration and concerted efforts are required to address existing challenges.
