Opis:: In this study, the functions and threats of Suraha Tal Wetland are identified by the stated preference method and weightage is given according to their rank. The objective of the study is to determine the total economic value of Suraha Tal Wetland. The direct value can be drawn from the market price and from a survey of the stakeholders. Suraha Tal Wetland is also famous for the presence of the Jai Prakash Narayan Birds Sanctuary, which makes it a biodiversity-enriched area. The indirect value has been drawn from a review of the literature on Suraha Tal Wetland and the relevance of this literature is justified through the comprehensive meta-analysis (CMA) software. The total valuation of the wetland has been calculated. The paper concludes with suggestions for a few management strategies for better wetland management.

Opis:: This investigation additionally recognizes partner cooperation issue and furthermore to moderate the real issue through subjective and quantitative appraisal of riverine wetland. Considering a floodplain wetland in rustic West Bengal, the concentration was extended to perceive the type of wetland capacities as per the idea of individuals’ contribution by group examination. Be that as it may, NDVI was connected to ponder the total weeds condition into the wetland to decide the connection between Water Quality Index (WQI) with Normalized Difference Vegatation Index (NDVI) and its impact on valuation. In ANOVA, which is computed by MINITAB programming, centrality level was lower than 0.05 for each case.

Opis:: The development of reconstructed woody vegetation on coal mine dumps during the trajectory of reclamation was explicitly investigated by means of a rehabilitation technique. However, limited information is available about the composition of herbaceous species during the ecosystem re-development on mine dumps. The present study attempted to assess the composition of herbaceous vegetation beneath plantation stands of four native woody species on the coal mine spoil in a dry tropical environment. After a thorough survey of the study site, a total of 44 species of herbaceous plants belonging to 14 families were recorded. Among the recorded plant families, the Poaceae contributed the highest number of species (18) across all ages of all plantation stands. The biodiversity parameter such as species richness exhibited an increasing trend with age under plantation stand of T. grandis only, while the rest of the plantations showed a decreasing trend. In terms of the similarity index, the plantation stands of A. procera and T. grandis were closer to each other while A. lebbeck and D. strictus were farthest apart. However, the highest IVI was recorded in the seedling of A. lebbeck under the planted stand of A. lebbeck while lowest of Rungia repens (2.85) under A. procera stands at 17^th-year of age. In conclusion, the plantation age, dominant tree species, and species specificity have a significant impact on the development of herbaceous vegetation beneath the plantation stand of four native woody species.

Opis:: Efficient extraction of coal from an underground mine is mainly done under the protection of different forms of coal pillars. It is observed that the coal seams and its host rock contain different geological discontinuities such as weak beds (bands), which affect the strength of pillars. The weak bed creates weak bedding planes. The available pillar strength formulae are based on the width-to-height ratio, depth of cover, and strength of intact coal, and they do not consider the effects of discontinuities. A numerical simulation study on the quarter symmetry model is carried out to assess the impact of weak beds with their positional variation and thickness. The strength of the pillar without discontinuities estimated through the simulation study was validated with those obtained by the indigenous empirical strength formula. A weak bed of 0.2 m, 0.3 m, 0.4 m, and 0.5 m thick was incorporated into the model within the pillar height at different positions and studied its impact on pillar strength. A simulation study revealed that the presence of a weak bedding plane at different positions in the pillar system reduces the strength of the pillar from 3.50% to 15%. However, it was found that the strength is reduced more in the case of a weak roof-pillar interface.

Opis:: RADAR plays a vital role in military applications since its origin in the 2nd world war. Recently it has been used in surface inception, health monitoring, infrastructure health monitoring, etc. In these applications, Ultra-wideband RADAR systems are more popular than traditional RADAR systems. Impulse RADAR is a special kind of ultra-wideband RADAR, which is mostly used for surface penetration, through-wall imaging, antimissile detection, anti-stealth technology, etc. because of its high resolution and low center frequency. Out of all these applications, impulse RADAR has been used intensively as a ground-penetrating RADAR for the detection of land mines, underlying pipelines, buried objects, etc. This report has attempted to provide the steps for designing the impulse ground penetrating RADAR (GPR) as well as provides the value of crucial parameters required in the design process of commercial GPR systems.

Opis:: Electrical discharge machining (EDM) is a non-traditional machining process widely used in manufacturing to create complex geometries on hard-to-machine materials. The tool material used in EDM plays a crucial role in determining the machining performance and final surface finish of the workpiece. In this research, we aimed to optimize the tool selection for creating circular holes on SG iron (grade 450/12) using EDM. To this end, we employed a step-wise weight assessment ratio analysis (SWARA) based combined compromise solution (CoCoSo) approach to evaluate the performance of different tool materials under various machining conditions. The machining conditions considered in this study included peak current (I), pulse-on time (Ton), and inter-electrode gap (IEG). The results of our study showed that the CoCoSo approach is an effective method for tool selection in EDM, and it can be used to identify the optimal tool material and machining conditions for creating circular holes on SG iron. The final appraisal scores obtained from the ranking of tool materials indicated that copper tools scored highest (2.4767, ranking 1), followed by copper tungsten (2.3615, ranking 2), while brass scored lowest (1.6606, ranking 3). Furthermore, Spearman's rank correlations for different integrated MCDM techniques were performed, which demonstrated the efficacy of this technique. It has been demonstrated that implementing the SWARA-CoCoSo method can effectively optimize the EDM process with regard to sustainable machining practices.

Opis:: India is an immense medicinal plant repository, used in traditional medical treatments. The use of herbal medicine is growing day by day due to toxicity and allopathic drug effects. About 90 percent of the phytochemicals marketed come from wild resources and over 120 major phytochemistry come from plants. Aegle marmelos leaves contained π-sitosterol, aegelin, lupeol, rutin, marmesinine, flavone, glycoside, Oisopentenyl halfordiol, marmeline, and phenylethyl cinnamides. The additional growth promoters show its effect on tissue culture of plant.

Opis:: Polycarbonate is widely used as structural material due to its extreme resistance to impact and perforation. In a crime involving firearms, the bullet may impact various objects fitted with or made of polycarbonate sheets leaving high chances of discovering the fractured PC sheets and fragments at the scene of crime; hence, these objects may become objects of the criminal investigation. In the present work the perforation pattern of PC sheets of thicknesses 8 mm, 10 mm, 12 mm and 15 mm at firing ranges 5 m and 10 m when impacted against 9 ×19 mm full metal jacket (FMJ) bullet were examined. It was observed that after impact, the PC sheet develops entry hole smaller than the calibre of bullet; formation of crack zone, plastic zone; and petalling on the distal face was observed. It was found that as the thickness of the sheet increases, the diameter of the entry hole increases, the diameter of the exit hole initially increases and then becomes constant. At 5 m range of fire the trend of crack zone becomes nearly constant from 8 mm to 15 mm thickness, however, at 10 m range of fire crack zone increases from 8 mm to 15 mm thickness. Furthermore, the diameter of the plastic zone increases as the thickness of the sheet increases (from 8 mm to 15 mm, respectively).
