Analysis of Radar Interferometry Results on the Deposit Territory
For effective and safe development of mining deposits, it is necessary to study the impact of natural and anthropogenic factors on the development of deformation processes, which provides an opportunity to regulate their impact on the rock mass, earth surface and engineering structures. The size of the deposit, geology and production volumes, affects the area of deformation, which can spread over huge areas. Accordingly, regional deformation monitoring is required for such fields. In order to provide high detail coverage of the area, traditional ground-based methods are impractical and costly. More timely and cost-effective for monitoring deformation of large territories is the use of differential radar interferometry.
The results of high-precision geodetic measurements for the period 2019-2021 revealed that more observation points have significant negative values. This indicates a stable process of subsidence of the earth, predominantly. Analysis and interpretation of the obtained results of geodynamic monitoring (high-precision leveling, radar interferometry), allowed to determine that the condition for the formation of vertical and horizontal deformations of the earth's surface is a natural-technogenic factor
Effects of Magnetized, Chelated Iron Foliage Treatments, and Metal Halide Lamps on Plant Water Structure, Water Vapor Dynamics, and Resilience for Legumes under Water Stress
A greenhouse study was conducted to determine the effects of foliar applications of magnetized, chelated liquid iron fertilizer for increasing the drought tolerance of two legumes. The study objectives were to determine the drought tolerance effects of four treatments on foliar gas exchange, soil moisture, and plant growth for soybean (Glycine max) and velvet bean (Mucuna pruriens) plants. The plant treatments included applications with chelated liquid iron fertilizer (2.5 and 5%) with a conventional boom sprayer, with and without magnets in the spray lines, and metal halide lamps. Three gas exchange measurements were collected before applying the foliage treatments and after two water stress treatments. A foliage and metal halide lamp treatment deactivated or unlinked nine interconnected gas exchange parameters that are correlated with plant defense activities during water stress conditions. The deactivation of interconnected regulatory gas exchange functions improved metabolic efficiency, reduced stress levels, and boosted plant resilience to abiotic stressors. Also, the study findings suggest that the study treatments maintained or increased the level of biologically structured water in plant tissues and vascular systems

This work covered essential technological progress in all the aspects of polyurethane foam growth, including cell nucleation and stability. The work also included developing an understanding of controlling cell morphology, size, and shape and improving closed and open-cell content. This necessitated a grasp of the character of surfactant catalysts, which also helps control the development of polyurethane foams. Learn the fundamentals of polymer physics and materials science to understand how the viscosity of polymeric matter impacts the most recent performance attributes of various flexible foams, including high elasticity, flex sheet stock, and viscoelasticity
Only the Greenhouse Gas, Water Vapor, Measurably Warms the Earth
Data is available for the 61 greenhouse gases (GHGs) in Table 2.14 of the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) to calculate their contribution to global warming in degrees Celsius. The procedure is described in the recently published study Reliable Physics Demand Revision of the IPCC Global Warming Potentials. In the current study, the contribution was calculated for each 61 GHG. The sum of the contributions of the 61 GHGs was 0.00833oC out of 26oC, which, for this example, is the difference in temperature between Pond Inlet and Amsterdam. This amount of temperature is too small to measure. Thus, with all other GHGs except water vapor eliminated as warming gases, water vapor is the only GHG that causes measurable warming of the Earth’s atmosphere. This is the exact result of the mathematical model of the Earth’s atmosphere developed in 1904 by Willis Carrier, i.e., the psychrometric chart, which is now a computer program, i.e., Humidair. Thus, the two methods used 120 years apart are robust and give the same result, confirming the unique role of water vapor in the temperature of Earth’s atmosphere and the virtually non-temperature role of the 61 GHGs
Antioxidant Effect of a Combination of S-Acetyl-L-Glutathione, Vitamin E, Silybum Marianum on Hepatic Cells under Oxidative Stress: An In Vitro Study
Oxidative stress plays a key role in the pathogenesis of liver diseases and can be involved in the inflammatory process of liver cells. The aim of this vitro study is to assess the antioxidant efficacy of three distinct components (fermented S-Acetyl -L-glutathione, Silybum marianum (L.) Gaern. and vitamin E all-rac-alpha-tocopheryl acetate) both individually and in combination (Glutasyl product). In addition, we also evaluated the combined antioxidant effect of the three ingredients on human hepatic cells subjected to oxidative stress induced by H2O2 treatment.
The results showed the dose-dependent antioxidant potential of the three components suggesting promising applications in medical contexts. The synergistic antioxidant effects observed for the Glutasyl was more than the individual components. Additionally, Glutasyl showed not-toxic activity on human hepatocytes and it could be considered useful in mitigating cytotoxicity induced by oxidative stress
Quasi-Static Compression and Microstructural Characterization of Polyurethane Foams for Potential Use in Shock Absorbers
This study focuses on the detailed characterization of modified polyurethane foams, emphasizing their quasi-static compression behaviour and microstructural properties, to evaluate their potential application in shock-absorbing systems. Through systematic synthesis, we produced various formulations of polyurethane foams. We subjected them to comprehensive quasi-static compression tests to understand their deformation and energy absorption characteristics under controlled loading conditions. Concurrently, microstructural analyses were conducted to elucidate the relationship between the cellular architecture of the foams and their mechanical responses. Although the foams were not directly integrated into shock absorbers, the findings lay a foundational understanding of how their structural and compositional variations influence performance metrics crucial for shock absorption applications. This research contributes to the broader knowledge base required for the future design and optimization of polyurethane foam-based shock absorbers, highlighting critical areas for further investigation and development
Protective Effect of Curcuminoids Consumption on Cadmium-Induced Testicular Injury in Albino Rats
This study evaluated the protective effects of curcuminoids against cadmium-induced testicular injury in Albino rats. Male albino rats were divided into nine groups, group 1 (control), groups 2-4 received 120 mg/kg, 240 mg/kg, and 360 mg/kg curcuminoids daily for 28 days without testicular injury. Group 5 received 20 mg/kg cadmium chloride (CdCl2) solution every other day for 28 days (positive control), while group 6 received 20mg/kg CdCl2 + 240 mg/kg curcuminoids every other day for 28 days. Group 7 received 20mg/kg CdCl2 every other day for 28 days, then treated with 240 mg/kg for 14 days. Group 8 received 20 mg/kg CdCl2 solution every other day for 28 days, then treated with 240 mg curcuminoids for 28 days. Group 9 received 20 mg/kg CdCl2 solution every other day for 28 days and left to recover 28 days. Serum and seminal plasma malondialdehyde, catalase, superoxide dismutase, glutathione peroxidase, and glutathione reductase were assayed using Spectrophotometry technique. Semen analysis was determined microscopically. Sperm motility and count were significantly reduced, acrosome defect and percent abnormal sperm morphology were increased among the positive control group when compared with negative control group (p<0.05). Serum GPX, GSH, and SOD, semen GPx , GSH and SOD were significantly reduced (p<0.001), while MDA was significantly increased (p<0.001) in CdCl2 administered rats than negative control. The supplementation of Curcumins resulted in the improvement of sperm quality indices in a dose-dependent manner. Curcumin supplementation may significantly reverse the adverse effects of cadmium chloride testicular injury
Reliable Physics Demand Revision of the IPCC Global Warming Potentials
The Global Warming Potentials (GWP) of the Intergovernmental Panel on Climate Change (IPCC) in Table 2.14 of the Fourth Assessment Report (AR4) show the increase in warming by methane (CH4) and nitrous oxide (N2O) is 21 and 310 times respectively that of CO2. There has been wide acceptance of these values since publishing in 2007. Nevertheless, they are inaccurate. This study uses accurate methods to calculate the impacts of CO2, CH4, and N2O on the warming of the atmosphere. For example, this quantitative analysis from reliable physics shows the contribution of CO2 to warming at Amsterdam is 0.0083oC out of a difference of 26oC. The warming effect of CH4 on the Earth’s atmosphere is 0.408% of that of CO2, and the warming by N2O is 0.085% of that of CO2. Thus, the warming effects of CO2, CH4, and N2O are too small to measure. The invalidity of the methane and nitrous oxide values indicates the GWPs of the remaining approximately sixty chemicals in the Table 2.14 list are also invalid. A recommendation is that the IPCC consider revising or retracting the GWP values in Table 2.14

This innovative approach enhances the material’s mechanical properties and usability in security applications, significantly advancing over traditional materials. By integrating alumina nanoparticles, we improve the composite’s strength and durability, which is critical for the reliability of non-lethal projectiles. Our findings contribute to materials science by providing a sustainable, efficient, and effective alternative for law enforcement and personal safety equipment
Feasibility of Proppant Flowback Control by Use of Resin-coated Proppant
Proppant flowback is a problem in Xinjiang oilfield. It decreases production rate of a fractured oil well, corrodes surface and downhole facilities and increases production costs. Curable resin-coated sand is a common technique to control proppant flowback. This article presents an experimental investigation whether it is feasible to control proppant flowback by use of resin-coated sand and whether resin-coated sand has a negative effect on proppant pack conductivity. It included two kinds of experiments, Proppant flowback experiment measured critical flow rate while the Proppant pack conductivity one measured proppant conductivity. The experimental results of proppant flowback show that the critical flow rate of resin-coated sand is far greater than that of common sand which means proppant flowback would not happen by resin-coated sand tail-in. Compared to Xinjiang sand conductivity, resin-coated sand conductivity is far smaller though it declines slightly which means use of resin-coated sand would lead to conductivity loss and sequentially results in production impairment. Experimental results show that it is feasible to control proppant flowback by use of resin-coated sand and resin-coated sand would affect fracture conductivity of a fractured oil well. Based on the experimental results, resin-coated proppant conductivity can be improved by use of resin-coated ceramic or liquid-resin-coated proppant. The achievements can give a direction towards how to select a resin-coated proppant and how to improve resin-coated proppant
