Published: June 2024

The crop water requirement of rice in different agroclimatic zones of Jharkhand, India was estimated using the CROPWAT 8.0 and CLIMWAT 2.0 models with data collected through NASA data-access-viewer on climate, soil, crop, and water availability.  The evapotranspiration (ETo), effective rainfall (Peff), and crop water requirement (CWR) for the four zones of the Jharkhand State were calculated. Results revealed that the reference evapotranspiration (ETo) varied from 420.4 mm to 516.5 mm during the crop growing season of rice in different zones. The effective precipitation varied from 748.4 mm to 760.8 mm. The crop water requirement of rice varied from 482.5 mm to 592.4 mm. Effective rainfall was sufficient to meet the water requirement of rice in most of the zones except Alluvial zone wherein the net irrigation water requirement was only 67.6 mm.

Authors: P. MANIKANDAN  , R. RENGALAKSHMI
Published: June 2024

The field experiments were conducted to study the relationship of major moringa pests infesting buds (budworm), flowers(ants) and pods (podfly) with weather factors (maximum and minimum temperature and relative humidity and rainfall) during the rabi-summer and kharif seasons of 2021 and 2022 in Dindigul district, Tamil Nadu. The pest population data indicated that the infestations were found to vary with the seasons as well as years. The correlation with weather parameters revealed that the budworm infestation was significant and positively correlated with maximum temperature (r= 0.459***) and negatively correlated with morning relative humidity (r= -0.277*), evening relative humidity (r= -0.584***) and rainfall (r= -0.459***).  While in infestation by ants, it was positively correlated with the maximum temperature (r=0.42**) and minimum temperature (r= -0.296*), relative humidity (evening) (r= -0.649***) and negatively correlated with rainfall (r= -0.382**). The moringa pod fly infestation had a strong significant positive correlation with relative humidity (evening) (r= 0.7***) and rainfall (r= 0.517***) and a negative correlation (r= -0.518***) with maximum temperature. The stepwise linear regression showed that all the weather factors collectively influenced the budworm infestation by up to 60.7 %, ants infestation by 50.5 % and up to 60.7 % in podfly infestation.

Published: June 2024

Field experiments were carried out to study the population dynamics of citrus psylla, Diaphorina citri Kuwayama on Kinnow Mandarin for twelve years (2007-08 to 2019-20) in relation to different weather parameters and to develop population prediction model. Adult psyllids were observed throughout the year but the population was very low during November-January. Two population peaks were observed during March and September. Highest mean population (80.8 nymphs/25 twigs) was observed during second fortnight of September which varied in different years. Psyllid population showed significant and positive correlation with maximum and minimum temperature, vapour pressure, wind speed, sunshine hours, rainfall and negative correlation with relative humidity and number of rainy days. A weather-based model was developed to predict psylla population seven days in advance. The validation of the model carried out using various indices viz, root mean square error, coefficient of determination, Nash-Sctuliffe efficiency and mean bias error suggested that, the model predicted the population of citrus psylla quite satisfactorily. Thus, the developed model can be used satisfactorily for weather-based prediction of citrus psylla in Punjab, seven days in advance.

Authors: GOSWAMI PURBA , SAHA SARATHI , LALU DAS  , SAON BANERJEE
Published: June 2024

Present study examined the overall performance of 12 CMIP6 GCMs for rainfall, maximum and minimum temperatures for rice crop-growing seasons i.e., Boro (January to May) and Kharif (June to October) over the new alluvial zone of West Bengal. A wide range of indices i.e., index of agreement, error indices and bias estimators were utilized to put more confidence on the results. Results indicated that CMIP6 models were able to reproduce observed mean climatology and inter-annual variability of maximum and minimum temperature adequately for both seasons while a smaller number of models (3-4 models) out of a total of 12 GCM-CMIP6 models showed satisfactory performance for rainfall. The ranks assigned to the models revealed that CNRM–ESM2–1 was the best-performing model for Kharif and MRI-ESM2-0 showed the highest skill for Boro. ACCESS-CM2 and MPI-ESM1-2-LR performed worst for Kharif and Boro seasons respectively. Further, CNRM–ESM2–1 and MRI-ESM2-0 were used to project the future climate for Kharif and Boro seasons respectively under both moderate (SSP2-4.5) and extreme scenarios (SSP5-8.5). Higher warming was projected during Boro season than Kharif. Projections revealed increasing rainfall during Kharif season but decreasing rainfall in Boro season in both the moderate and extreme future scenarios.

Published: June 2024

This study examines the possible effects of climate change on sorghum in the western zone (WZ) comprising Coimbatore, Tirupur, and Erode districts of Tamil Nadu. The DSSAT crop simulation model was used to simulate sorghum yields with considering various planting dates and amounts of fertilizer application. The downscaled CCSM4 climate model data was utilized for the historical baseline period spanning from 1991 to 2020, as well as for future projected data from 2021 to 2099, under the RCP 4.5 scenarios. The key findings indicate that there is a projected yield decline range of -1.3% to 12.5% for the near century (2021-2040), -6.2% to -23.7% for the mid-century (2041-2070), and -12.6% to -30.5% for the end century (2071-2099). The sorghum yield experiences a high decrease at the end of the century (276.83 kg ha-1), mid-century (178.16 kg ha-1), and lastly in the near century (89.4 kg ha-1). The study revealed that a enhanced fertilizer application can have a minor positive effect on sorghum productivity. The study underscores the significant threat that climate change poses to food security in Tamil Nadu and emphasizes the need for adaptation strategies to protect agricultural productivity.

Deciphering the complexity of cataract surgery: A bibliometric and science mapping analysis of research patterns and surgical developments- a 40-year perspective
Authors: Yurdakul Bilge
Published: June 2024

Cataract surgery, an integral facet of ophthalmological intervention, has experienced profound metamorphosis over the past 40 years. These shifts have been marked not only in the domain of surgical methodology but also within the conceptual framework that governs the understanding, diagnosis, and management of the condition. This research endeavors to articulate the contemporary landscape of cataract surgery, delineating its chronological evolution, emergent trends, and intricate interconnections, spanning a period of four decades. The methodology employed a thorough exploration and meticulous analysis of the Web of Science (WoS) database, concentrating specifically on cataract-related research from 1983 to 2022. The corpus, comprising 9574 articles, underwent rigorous examination through bibliometric and science mapping instruments, including Bibliometrix, to assay the patterns, significant authorships, journal participations, and theoretical architecture in the field of cataract studies. The inquiry revealed a compounded annual growth rate of 3.82% in cataract research, with a mean citation index of 23.18 per article. This corpus encompasses contributions from 90 journals. This study was integral to the identification of seminal researchers, authoritative institutions, and cornerstone publications. The analysis was segmented into four analytical domains: an exploration of the fundamental structure of articles, an evaluation of author and journal participation, a scrutiny of keyword deployment, and an analysis of conceptual paradigms, uncovering substantial thematic interconnections and trends. This analytical endeavor systematically deconstructs the multifarious nature of cataract surgery and affiliated research, thereby unveiling a rich, multidimensional field that extends its influence and applicability beyond ophthalmology to a myriad of interdisciplinary pursuits. As an academic synthesis, the insights garnered from this study provide an unparalleled reference for scholars, clinical practitioners, and policymakers who have deeply invested in cataract surgery. This signifies the field's progressive evolution over an extended temporal frame and critically elucidates prospective avenues for scholarly inquiry and practical application, thereby fulfilling a vital niche in contemporary medical literature.

Published: June 2024

The fact that DNA cannot be used for identification in some cases due to the small amount of sample or degradation due to environmental conditions increases the importance of RNA. In this direction, studies are carried out on the use of miRNA markers in the detection of body fluids in forensic sciences. The focus of the study is the identification of the miRNA biomarkers hsa-miR-203a-3p and hsa-miR-451a, especially in bloodstains exposed to environmental conditions. The samples that were created by the modeling method were kept in different environmental conditions for 45 days and then miRNA markers were investigated. As a result of the analysis, hsa-miR-451a expression was observed in the samples kept at -20°C and +4°C and in sealed bags, while hsa-miR-203a-3p expression was not observed. This study proposes the use of RNA and especially miRNA instead of DNA in forensic sciences. In conclusion, this study points to the importance of using miRNA profiling in forensic science. In particular, the identification of bloodstains taken from the crime scene and exposed to various environmental conditions with the miRNA biomarker hsa-miR-451a may be an important step in future forensic science applications. Since this study was carried out as a master's thesis, it was studied with a small sample group, and the results were intended to form a basis for future studies. Increasing diversity with larger sample groups in future studies is scientifically valuable.

Published: June 2024

This study aims to determine the relationship between study time and academic achievement of business school students in Aligarh (INDIA). The poll involved 209 students divided into three distinctive groups based on regular weekly study hours: 2 to 4 hours, 4 to 6 hours, and above 6 hours. In all, 209 students responded to the survey. Academic performance was evaluated with high, medium, and low grades; these grades were classified into five different groups depending on the grades: below 60%, between 60% and 70%, between 70% and 80%, between 80% and 90% and above 90% Such information was used to determine the extent to which the person had succeeded in their life of the mind. The results also corroborate several ways the duration of study time is related to grade, consistent among the properties studied. They realized that students who studied 4 hours to 6 hours per week had a better tendency to become great scorers, and a high percentage of them scored 70 to 90 or even more than that. Many of our children were in this category. However, there was a broad range of achievement among students who devoted over six weekly hours, suggesting that it only sometimes pays to study harder than one would have studied. Moreover, the results of academic research have provided evidence that a moderate time, between four to six hours per week, spent studying is helpful to enhance academic performance as opposed to either minimal or maximal study, which was proven to be detrimental. This serves as a reminder to be more balanced in studying. The research also stresses the importance of balanced study habits. Through these principles, instructors, and students in Aligarh and other academic environments will be expected to learn effective styles to improve academic performance. They could expand their time on tasks to save time studying and improving their GPAs and education.

Published: June 2024

More than forty years after the 23 November 1980 earthquake, which devastated the Campania and Basilicata regions, causing the destruction of a large number of towns and the death of around three thousand people, we have tried, through a large survey, to understand how and to what extent the urban fabric and the most affected communities have been rebuilt. Our main objective was to show, on one side, the commitment of the scientific community, and on the other the transitions that have led from the emergency to reconstruction. Of the Apenninic towns Conza della Campania, Laviano, Lioni, Santomenna, and others, where the devastation was almost total, we have tried to give an iconographic vision of the post-earthquake phase through the change in the urban layout. The partial or total reconstruction of the towns has taken place most of the time in situ, only in some cases by relocating buildings to neighboring areas, as happened in Conza della Campania, Bisaccia and Romagnano al Monte. Reconstruction was carried out mainly of anti-seismic buildings and only in some cases recovering pre-existing buildings in historic centres; reconstruction was completed after a very long period, in some cases lasting over thirty years, inevitably passing through a dramatic experience of the population in temporary settlements of various kinds, from tents, caravans, railway carriages, to containers, and finally to thermo-igloos and to prefabricated wooden chalet-type. A very complex and detailed reconstruction was linked to factors not only territorial, economic and political but also conditioned unfortunately by the non-negligible intervention of organized crime.

Authors:   Shri Sant Gajanan Maharaj College of Engineering, Shegaon, Raju Suresh
Published: June 2024

Additive manufacturing (AM) has emerged as an effective method for fabricating parts with internal complex features. However, optimizing process parameters to achieve desired mechanical properties for such complex geometries remains a challenge. This research aims to systematically evaluate the influence of AM process parameters on the tensile strength of PLA plus specimens containing a rectangular channel integrated inside the gauge section. A Taguchi L9 orthogonal design of experiments was formulated with four control factors - printing temperature, layer height, wall line count and infill percentage. Tensile testing specimen of standard ASTM D638-Type I containing a rectangular channel of 1.5x5x50mm was printed on an FDM machine. Tensile testing determined the ultimate tensile strength and percentage of elongation as the response. Signal- to-noise ratio analysis revealed optimized levels as 210°C, 0.20mm, 3 wall lines and 100% infill. Tensile testing of specimens printed at these conditions yielded average UTS of 34.58 MPa. Adopting Taguchi methodology, this study aims to improve understanding of interplay between key AM parameters and mechanical properties for PLA plus specimens with complex internal geometry. Optimized settings aid quality fabrication of functionally graded parts with intricate designs using this sustainable FDM material. Statistical design of experiments serves as an efficient evaluation approach. Key Words: Additive Manufacturing, Fused Deposition Modelling, PLA, Tensile Test Specimen

Authors:   Siddhartha Institute of Technology & Sciences, Narapally, Ghatkesar, Medchal-Malkajgiri, Telangana, India
Published: June 2024

Applications in digital signal processing that are inherently tolerant of inaccurate computing results are the ones that first use approximate computing. These circuits' electrical performance is enhanced by utilising the approximate arithmetic blocks. Some of the most basic building elements of computer mathematics are multipliers. In addition, the parallel multipliers frequently use the 4-2 compressors to speed up the partial product compression process. Three novel approximate 4-2 compressors used in 8-bit multipliers are shown in this letter. The approximation multiplier's error performance is enhanced when an error-correcting module (ECM) is paired with the recommended 4-2 compressors. An improved level of energy efficiency is brought about by this short by halving the number of outputs from the projected 4-2 compressor. Simulated findings show that the suggested approximation compressors UCAC1, UCAC2, and UCAC3 reduce latency by 24.76%, 51.43%, and 66.67%, power by 71.76%, 83.06%, and 93.28%, and area by 54.02%, 79.32%, and 93.10%, respectively, as compared to the exact 4-2 compressors. And using these suggested compressors in 8-bit multipliers results in an average power consumption reduction of 49.29%. Index Terms - Ultra-Low Power, Compensation Characteristic, 4–2 Compressors.

Kejaksan Square has become a tourist attraction in Cirebon City since it was renovated in April 2021. However, the implementation of parking policies there still faces obstacles such as lack of public awareness, lack of commitment of officers in socializing parking rules, and lack of adequate parking infrastructure. This study aims to evaluate the implementation of parking implementation policies in the Cirebon City Kejaksan Square. Qualitative and descriptive research methods are used, by collecting data through observations, interviews, and documentation. Edwards III's theory of policy implementation is used as a theoretical framework. The results showed that communication, resources, disposition and bureaucratic structure affect the implementation of parking policies. Despite the obstacles, the active role of the Department of Transportation and the availability of adequate resources provided support for the success of the policy. The ultimate goal is to improve the quality of public facilities and infrastructure services that are environmentally friendly.

The demand for electricity is continually increasing. Typically, electrical energy is generated using fossil fuels such as coal in thermal power plants. Generally, these power plants or other electricity generators supply power to densely populated areas such as large cities. Remote areas, however, often lack access to electricity due to their distance from urban centers. One solution to this issue is the development of micro-hydropower plants (MHPs). In MHPs, turbines are generally made of metal, which has high inertia and thus leads to lower efficiency. Therefore, this study replaces the turbine in an MHP with one made of fiberglass to assess the material's resistance to the water pressure in MHP operations. Based on the research conducted, the allowable stress for the fiberglass was determined to be 11.59801 MPa, with the water pressure applied to be 0.000985 MPa.

Renewable energy utilization has become a primary focus in addressing the negative impacts of fossil fuel usage for electricity needs. One proposed solution is using water flow energy through a Pelton turbine. However, traditional materials used in Pelton turbines, especially metals, have disadvantages such as high inertia and susceptibility to corrosion. In this study, we replaced the Pelton turbine's material with fiberglass composite, which offers lower inertia and better corrosion resistance. This study aims to evaluate the performance of the Pelton turbine using fiberglass composite material. Tests were conducted by connecting the turbine to a generator and installing three adjustable nozzles, divided into seven sections based on the number of nozzles opened. Voltage, current, and electric power were measured using a power meter. The results show that with a load consisting of LED light bulbs, the section with one nozzle open (Section 2) achieved the best power output of 1.11 watts, while the section with two nozzles open (Section 6) achieved the best power output of 1.66 watts. Without load, the highest voltage occurred in Section 2 with one nozzle open at 30.9 volts, while the highest power was recorded in Section 4 with two nozzles open at 31.26 volts

Water scarcity is a growing challenge in many regions around the world, including Nigeria, where precipitation patterns have a significant impact on water availability for human and ecological systems. This research paper explores the role of precipitation in sustainable water management, drawing insights from atmospheric science research. In particular, we conduct a trend analysis of precipitation in key areas of Nigeria using the new Innovative Trend Analysis (ITA) method. ITA is a powerful statistical method that allows for the detection of trends and periodicities in time series data, even in the presence of non-linear trends and data uncertainties. Our analysis aims to provide a better understanding of how precipitation has changed over time in Nigeria and what implications these changes have for water management strategies and practices. The potential for atmospheric science research to inform future water policy and planning decisions are also discussed. The examination of precipitation trends using the ITA approach revealed a range of patterns, from reducing or trendless scatter points in the southern vegetation zones to increasing precipitation trends in the savannah regions; this emphasizes the need for context-specific water management strategies. Regions experiencing declining precipitation may necessitate adaptive measures to address potential water scarcity, while those with increasing trends require strategies to mitigate potential flooding risks. By combining meteorological data with reviewed insights from other disciplines such as hydrology, ecology, and economics, we can work towards a more sustainable and equitable management of water resources in Nigeria and even beyond.
