Authors: Dalal Yash , Rana Saksham , Kesari J.P.
Published: January 2024

India’s contributions to the development of alternative energy sources are substantial. India has almost tripled the capacity of its renewable energy installations over the last five to six years, with coastal wind and solar photovoltaic (PV) installations accounting for the vast bulk of this growth. Since land scarcity is a big challenge nowadays, it is an excellent idea to construct solar plants on rivers, lakes, and dams, which are otherwise idle water bodies. The progressive depletion of fossil resources and the ever-increasing need for electricity both pose serious obstacles to progress. The electricity generated by floating solar photovoltaic systems is significant. India has completed a number of large-scale projects, including the 100MW Ramagundam, Telangana project and the NTPC Simhadri Solar Plant. This investigation highlights the potential benefits and challenges of these plants. Feasibility analysis of 5MW FSPV at Somasila Dam, Andhra Pradesh is also done in this paper. Additional to this, the article gave the economic and technological analysis of floating solar photovoltaics, in addition to discussing several case studies.

Authors: Ghosh Pritam , Ramajeyathilagam K.
Published: January 2024

This work focuses on the numerical investigation of the ballistic and delamination mechanisms of T700 carbon fibre/epoxy laminate with a [0/90]s stacking sequence. The effect of the mass and diameter of spherical projectiles on CFRP laminate is investigated numerically. A numerical study of projectiles with different diameters (6mm, 10 mm, and 12mm) on CFRP laminates with thicknesses of 1.5mm and 3mm is conducted, encompassing a broad spectrum of projectile incident velocities (from 500 m/s to 1700 m/s). Furthermore, a numerical model containing cohesive elements is developed and verified using experimental results from the literature. When compared to experimental results, the numerical simulation results were found to be within acceptable ranges. On comparing the effect of laminate thickness, it was determined that 1.5mm laminates had better energy absorption capability as velocity increased compared to 3mm laminates. The results indicated that the energy absorption capability of the 3mm laminate was reduced by 8.8%, whereas the 1.5mm laminate was reduced by 3%. A study using multi-layered laminate is studied, and a parametric study is carried out with projectiles of different mass and size. The results from the parametric study concluded that smaller geometry projectiles induced more significant damage in the laminate than larger geometry projectiles with constant mass.

Published: January 2024

Due to the spread of corona virus, healthcare systems are facing significant strain, with an increase in demand for medical supplies and healthcare professionals. Many solutions were proposed in that sense, especially with the emergence of the Internet of Things (IoT) as a powerful communication and information technology. This paper proposed one of the approaches targeting the environmental health as a whole. This is especially to decrease the pressure on health systems during crisis times. It is mainly about the creation of a real-time corona virus monitoring system. It is in the form of a wristband that measures the blood oxygen levels and the body’s temperature. These measurements are essential in determining a patient’s health status and the need for immediate ICU intervention. Additionally, the wristband has a tracker that can be used to monitor the patient’s adherence to social distancing guidelines. Once the patient’s parameters are above a certain threshold, the doctors and health professionals are notified instantly. This device is very optimal in terms of energy consumption. It is considered as a promising tool in handling the spread of the virus by providing patients and healthcare providers with instant access to healthcare services, regardless of their location.
A Review of Traditional and Data-Driven Approaches for Disruption Prediction in Different Tokamaks
Authors: Priyanka M. , Sangeetha J. , Jayakumar C.
Published: January 2024

Tokamak is a nuclear fusion reactor; inside, the two lighter nuclei known as deuterium and tritium are first ionized together to form plasma, which is heated up to 150 million degrees Celsius, and then they are confined by the torus-shaped magnetic field. During this process, it releases a massive amount of energy, making fusion a feasible option for a long-term and renewable source of energy. On the other hand, plasma leads to disruptions as a consequence of the sudden implosion of the system, which halts the fusion process. Disruptions can irrevocably harm current fusion devices and are predicted to have a more catastrophic impact on feature devices such as ITER since they cause a rapid loss of confinement. To control, and prevent disruptions, or at least lessen their negative impact by mitigating them, various traditional and data-driven models obtained with machine learning and deep learning techniques have been used, an overview of some of which is presented in this article. These models are commonly used to forecast their occurrence and give sufficient time to take some counteractive measures.

Carbon nanotubes (CNT) and graphene have widely used as reinforcements in epoxy for various aims and applications since their ‘discovery’. For example, in the area of aviation and aerospace materials, carbon reinforcements are desirable as they offer solutions for light weight yet mechanically enhanced materials. The objective of this work is to investigate the effects of adding combination of carbon fillers of different aspect ratios on the thermal mechanical, Young’s Modulus and Fracture Toughness properties of the resultant epoxy composites. The carbon fillers include carbon nanotubes (CNT), graphene, and carbon black (CB) and their combined loading will be varied from 0.5 wt. % until 7 wt. % to form sets of binary epoxy composites and a ternary epoxy composites. All of the fillers are kept at the 1:1 weight ratio for CB + CNT, CB + Graphene, CNT + Graphene, and CB + CNT + Graphene. Among these combinations, the system with ternary fillers at 7 wt.% demonstrated the highest value of glass transition temperature (Tg) and KIC, and Young’s Modulus. The percent improvement for glass transition temperature (Tg) and KIC, and Young’s Modulus compared to neat epoxy are 9.5 %, 571%, and 58.3%, respectively. This work clearly demonstrated the effectiveness of employing various carbon fillers with different aspect ratio and morphology in enhancing the values of mechanical properties of epoxy system.

Published: January 2024

Since the dawn of civilization, grain storage has been necessary to ensure food security. Grain storage has a more extended history than one might think and is connected to farming history. India is the next-largest producer of wheat, followed by China. In terms of food security, storage is primarily intended to keep grains for a longer time. It guards against degradation, exposure to the outside environment, and potential microbe and insect attacks. Silo, CAP storage, and Godown storage were used to test the wheat’s temperature and moisture content. To obtain the reading, a temperature sensor and a RH sensor were installed within the silo. Grain storage in underground pits was employed in the past and is still used in some regions today. The holes were excavated and measured at 1 m in diameter and 1 m in depth, with a mixture of 3:3:1 cow dung, straw, and sorghum, amounting to around two quintals each. A total of 10–20 wheat samples kept in the silo were examined for fungus and fungal development. The samples were placed inside a glass bottle filled with sterile water and closely watched to ensure that no fungal source entered the container used for collection. Each colony was isolated and purified separately once it emerged to obtain an isolated single fungus. The pure fungus was positioned and examined using imaging and organized on figurative plates under a microscope. The germination percentage in various storage arrangements was tested for seed viability using wet paper towels. For the following three months of storage, the temperature within the silo increased rapidly from 28°C to 35°C. The grain retained its quality during the first three months, and there was little to no infestation. The lower ambient temperature and measured relative humidity of 95–97% are to blame for this. Before drying, the moisture content in the silo increased from 11 to 17%. During the storage period from April 2006 to November 2006, the moisture content in Godown bag storage increased at the same pace as in the silo. Wheat moisture content rises in direct proportion to its storage time. This is thought to be the result of an increase in insect population brought on by the respiration of insects and wheat, which helped raise moisture content. All of the isolated fungi in the silo were discovered to produce a significant number of spores and conidia on their surfaces. Aspergillus is a harmful toxin-producing fungus well-known for damaging various seeds, grains, and nuts. It is also famous for its destructive properties.

Authors: Ettahiri Lahcen , Benazzou Lotfi
Published: January 2024

This research aims to explore how eco-taxes contribute to achieving sustainable development goals, such as protecting the environment from pollution. The environment faces the threat of pollution, prompting countries to seek ways of mitigating its negative effects through the application of preventive or control tools and methods, in this case eco-taxes. Morocco is one of the countries suffering from environmental problems, which is why our country has adopted the concept of sustainable development. Environmental protection is one of the necessary elements to achieve the sustainable development goals. As a result, it has worked to develop an arsenal of laws and legislation to protect the environment against deterioration and pollution. Achieving sustainable development in Morocco requires a number of legislative and control mechanisms, including eco-taxes, which contribute to sustainable development as a deterrent and incentive. In this context, our research is based on qualitative research using documentary analysis. The most important result of our study is that eco-taxes are a powerful incentive for innovation if they are better selected, that they also improve competitiveness by offering low-emission alternatives, and that the use of eco-taxes are preferable to the application of regulatory tools in terms of cost.

Published: January 2024

The study aimed to compare zebrafish embryo mortality rates under different 2-Methylimidazole (2-MI) and 4-Methylimidazole (4-MI) concentrations. Two exposure groups were created at a 40μM concentration using egg water. Thirty individuals were divided into two groups: Group 1 received an environmentally relevant dose of 2-MI, while Group 2 was exposed to 4-MI. Each group’s embryos (n=15 per plate) were observed from 4 to 96 hours post fertilization (hpf), adhering to OECD guidelines. Statistical analysis using SPSS maintained a 95% confidence level, 0.01 ratio, 80% power, and 1:1 enrollment ratio. Results showed a marked increase in mortality rate (71.87±1.25) in ecologically exposed embryos compared to 2-MI (45.73±0.79), with a significant P-value of 0.000 (P<0.05). Additionally, zebrafish exposed to 4-MI displayed a 20% lower mortality rate than 2-MI, supported by a significance threshold of p = 0.000 (p<0.05). These findings highlight the detrimental impact of early exposure to 2-MI and 4-MI on zebrafish embryo mortality rates, signifying developmental and embryotoxic implications.

Authors: Tukhtashev B.B. , Norkulov U. , EIzbasarov B.
Published: January 2024

The use of saline soils for agricultural production is a major challenge. A study investigated the resistance to salinity, yield, and product quality of five crops (alfalfa, sunflower, white sorghum, sorghum, and millet) grown on weak, moderate, and strongly saline soils in Uzbekistan. The results showed that the crops were more resistant to salinity on weak and moderate soils than on strongly saline soils. The highest yields were obtained on weak soils, while the lowest yields were obtained on strongly saline soils. The product quality of the crops was also affected by salinity, with the best quality being obtained on weak soils. The study provides valuable insights into the use of saline soils for agricultural production. Saline stress has been the one of the biggest hurdles in achieving the demand and supply ratio of global population. To combat the growing problem of soil salinity, advanced soil management and irrigation technology are used. However, they are cost and energy intensive. Plant growth promoting rhizobacteria (PGPR) attained from saline soils can overcome the detrimental effects of salt stress on plants. PGPR positively impact physiological functions of plants such as growth, yield and overcome disease resistance. T

Published: January 2024

The geological structure of the reservoir in Bozi-Dabei area is complex, and the longitudinal difference of rock mechanical properties of the reservoir is large. Most of the current evaluation techniques after reservoir reconstruction are based on the fitting of construction pressure based on the logging curve of a single well, so as to analyze the fracture morphology and the geometric dimensions of length, width and height after pressure. It is difficult to explain the fracture morphology and geometric parameters correctly because the interpretation methods used do not comprehensively consider the influence of natural fractures, 3D geological properties and 3D geomechanical properties. In order to explain the artificial fracture morphology more accurately, the target layer ant body is generated by using 3D original seismic data, and the natural fracture model of three different reservoir types in Bozi X block is generated, which provides geological basis for the integrated demonstration. By combining dynamic and static data and multidisciplinary methods, a one-dimensional rock mechanics profile model is established, and a three-dimensional geomechanical model of three different reservoir types in Block X of Bozi is established by combining geological model and deep diagenesis theory. The matching relationship between horizontal stress, fault strike and natural tensile fracture distribution is comprehensively analyzed and evaluated, providing a geomechanical basis for the evaluation of integrated reservoir reconstruction. Integrated geological model and geomechanical model are closely combined with engineering parameters to establish an integrated true three-dimensional artificial fracture model. On this basis, the optimization research and design of the parameters of displacement, liquid volume and sand ratio are completed. The optimal flow rate of Class I reservoir 6-7 (m³·min-1), Class II reservoir 5-6 (m³·min-1), Class III reservoir 4-5 (m³·min-1), Class I reservoir 600-700 m³, Class II reservoir 600-700 m³, Class III reservoir 500-600 m³, Sand ratio of 15%-20% for Class I reservoir, 15%-20% for class II reservoir and 20%-25% for class III reservoir are the optimal construction parameters, which provide guidance for field construction.

Carbon sequestration refers to the technology of capturing carbon and storing it safely instead of directly discharging CO2into the atmosphere. Rock salt is a promising CO2reservoir, and the underground rock salt structure formed by salt cavern reservoirs in geological history has a natural sealing function. Storing carbon dioxide in salt caves can ensure that carbon dioxide is stably stored underground for a long time. However, at present, there are few studies on carbon sequestration in abandoned salt caves. This study analyses the characteristics of carbonate-evaporite strata in the high fold zone of eastern Sichuan and qualitatively evaluates Triassic carbonate-evaporite layers formed in the depth range of 800-3000 m in various sedimentary basins in Chongqing. A large set of carbonates-evaporites are developed in Chongqing, and the carbonate rocks near evaporites have low porosity and permeability, which can be used as CO2storage caprock in salt cavities. Thick evaporated strata can also provide a good cover for CO2 storage in abandoned salt caves, which has great potential space resources.

Reservoir damage is an important factor limiting the productivity of coalbed methane wells. In this paper, the coal seam in a coalbed methane producing area in the southeast edge of Ordos Basin is taken as the research object, and the types of reservoir damage in this block are analyzed through the composition test of coal samples and the comparison of production conditions, and the targeted solutions are given. The results show that the main types of reservoir damage in this block are solid plugging and water locking damage. The dissolution rate of acidic plugging removal working fluid with hydrochloric acid, hydrofluoric acid, acetic acid and hydrogen peroxide as main components for pulverized coal in this block reached 13.73%. After acidification, the permeability increased by 1.8~6.9 times, and the porosity increased by 0.35%~2.87%, indicating that the plugging removal working fluid system can effectively dredge the liquid seepage channel, reduce the seepage resistance and achieve the plugging removal effect.

Atmospheric corrosion monitoring and evaluation are important means for studying the mechanism and behavior of atmospheric corrosion of metals. In view of the long cycle, cumbersome process, and poor data quality of the traditional outdoor hanging method, an innovative atmospheric corrosion data monitoring system has been designed to detect atmospheric environment data and metal corrosion data on site, and display the detection data of the equipment’s service location to users in real-time in the form of a “dynamic corrosion map”. This can provide a differentiated design for the anti-corrosion of important equipment such as power grid transmission and transformation engineering components Provide effective data support for engineering life prediction and operation and maintenance. At present, the system has been piloted and promoted in some network provinces, achieving good social and economic benefits.
Reservoir Development Geologic Modeling and Residual Oil Prediction Research
Authors: Fu Jinze
Published: January 2024

The aim of this thesis is to investigate the geological modeling methods in reservoir development as well as residual oil prediction techniques. Geological modeling is a crucial step in oilfield development, which involves the three-dimensional description of subsurface reservoirs and helps to better understand reservoir properties. Residual oil prediction, on the other hand, is an estimation of the future production capacity of the reservoir and is crucial for decision making and resource management. This study explores different geological modeling methods, including seismic inversion, core analysis, and wellbore data, and introduces a variety of residual oil prediction techniques, including numerical simulation and statistical methods. Through example analyses and case studies, this paper demonstrates the application of these methods in practical reservoir development and their potential to improve reservoir development efficiency and residual oil prediction accuracy.

Venous thromboembolism (VTE) represents a worldwide health challenge, impacting millions of people each year. The genesis of venous thrombosis is influenced in part by genetic components. Hereditary thrombosis is described as a genetically determined susceptibility to VTE. In the present study, a male patient was referred to our department presenting with multiple venous thrombosis events in different locations. Given a lack of identifiable risk factors, we aimed to investigate the possible genetic factor underlying venous thrombosis. Whole-exome sequencing was employed to examine genes linked to inherited thrombophilia in the proband. Putative variants were subsequently confirmed through Sanger sequencing within the family. The proband was identified as carrying two genetic mutations. One is the novel c.400G > C (p.E134Q) mutation affecting the final nucleotide of exon 5 in the PROC gene, potentially impacting splicing. The other is a previously reported heterozygous nonsense variant c.1016G > A (p.W339X) in the SERPINC1 gene. The proband inherited the former from her mother and the latter from her father. The presence of digenic inheritance in the patient reflects the complex phenotype of venous thrombosis and demonstrates the significance of an unbiased approach to detect pathogenic variants, especially in patients with a high risk of hereditary thrombosis.

Published: January 2024

Die Häufigkeit chronischer Schmerzen steigt im höheren
Lebensalter, aber die Diagnose wird oft durch verschiedene Faktoren erschwert,
z. B. durch andere Krankheiten oder eingeschränkte geistige
Fähigkeiten der Patienten. Die häufigsten Ursachen chronischer
Schmerzzustände im Alter sind degenerative Prozesse im Körper
und altersassoziierter Abbau. Die Schmerzbeurteilung und -behandlung bei
älteren Menschen erfordert angepasste Methoden, um eine Untererfassung
aufgrund möglicher geistiger Einschränkungen der Patienten zu
vermeiden. Es ist wichtig, mögliche kognitive, emotionale und
psychologische Beeinträchtigungen und Beschwerden zu
berücksichtigen, um eine detaillierte und genaue Therapie einzuleiten.
Eine genaue Kontrolle des Therapieerfolges ist unerlässlich. Im
Folgenden wird ein Überblick über die Epidemiologie, die Arten
und die Erfassung von Schmerzen bei älteren Patienten gegeben.
Darüber hinaus werden die Neuroplastizität im Zusammenhang mit
chronischen Schmerzen, schmerzverstärkende Faktoren und das
Gebrechlichkeitssyndrom betrachtet.
