One hundred twenty complexes of Pb(II) of the type 1 10 Pb1 3 X2 (where X= Cl or Br or NO3 or CH3COO and 1 10 L1 3 = macrocyclic ligands derived from the condensation of trimesic acid or ...þthathalic acid or squaric acid with different aliphatic diamines in 2:2 molar ratio) have been synthesized and characterized by elemental analysis, molar conductivity, Infrared and XPS i.e. X-ray photoelectron spectra data. An octahedral geometry was also established for them
Fifteen Ru (II) complexes of the type RuCl2(L) (where L= N4 donor macrocyclic ligands) have been synthesised by reaction of (RuCl2(DMSO)4 with fifteen macrocyclic Schiff base ligands containing N4 ...donors groups. The prepared fifteen RuCl2(L) complexes were characterised by elemental analysis, molar conductivity, UV-visible, IR, X- ray photoelectron spectra (XPS) and magnetic susceptibility measurementsand an octahedral geometry was proposed for all these complexes.
Image Fusion is a methodology of joining useful data of infrared and visible images into a single huge informative image. The infrared images are mostly dark and only more heat emitting objects can ...identify. The visible image provides more information about their surroundings. So to capture the both objects and surroundings we need to fuse both the images. In this paper we are analyzing and comparing different spatial and transform domain fusion methods like Average, Principal Component Analysis (PCA), Laplacian Pyramid Approach (LPA), Contrast Pyramid Approach (CPA), Discrete Wavelet Transform (DWT), Morphological Pyramid Approach (MPA) with Quantitative measures like Entropy (EN) and Peak Signal to Noise Ratio (PSNR). From the experimental results observed that Principal Component Analysis provided better information using EN and PSNR measures for all the image sets is same and satisfied with the visualization of fused image also.
Leucaena leucocephala (Lam.) de wit, and Prosopis juliflora (Sw) DC, were introduced across the country due to their wide importance andthey are posing threat to native trees and ecosystem because of ...their wild and invasive nature. Therefore, study of their invasive featuresbecomes important during the current rainfall shift as India is witnessing a decrease in average rainfall and rainy events but an increasein downpour events. Our study throws light upon these plants’ invasiveness and rainfall-adapted characteristics. We performed the studyin the Botanical Garden, Banaras Hindu University, Uttar Pradesh, India. The study included two experiments (1) Seed germination underdifferent treatments- 48% H2SO4 for 40 minutes (T1), Water at 100°C for 10 minutes (T2), one-day water-soaked seed (T3); (2) Seedlingssurvival percentage and growth-indices under different watering conditions i.e., 50 mL water per seedling every day (W1), 50 mL wateronce in four days (W2), 50 mL water once in ten days (W3). Result of this study revealed that P. juliflora exhibited better germinationspeed and percentage in all three treatments (T1, T2, T3) in comparison to the L. leucocephala, while under T1 treatment, both exhibitedbest germination. On the 60th day of experiment maximum survival percentage was recorded under W2 water condition but maximumroot length was observed under W3 treatment for L. leucocephala and P. juliflora while maximum stem height was found under W1 andW2 treatments for L. leucocephala and P. juliflora respectively. These finding would conclude that P. juliflora is more potential invaderin comparison to L. leucocephala as this gave the best result under the drought stress condition W2 and W3 for all the parameters andstudy performed. Study also highlight the need of mitigation measures to curb the unlimited growth of P. juliflora under the presentscenario of rainfall shift favouring the invasion of drought tolerating plants.
Failure of the rear axle shaft of a heavy vehicle was thoroughly investigated. It was noticed that the axle shaft had failed during service and broken into two pieces. Different types of ...investigations were carried out on the failed axle shaft which includes visual examination, chemical analysis, Mechanical testing, Fractography and ultrasonic testing. Several cleavages were noticed in the Fractography, which depicted a sign of brittle fracture. Fatigue striations were observed in scanning electron microscopic analysis of the as received failed axle, which a typical indispensible characteristics of fatigue failure. The tensile fracture surface revealed mixed component of dimple as well as cleavage facet. Results indicated that failure occurred due to sudden loading on the axle shaft. The shear stress in the weak portion of the axle was not sufficient to counter the stress imposed by sudden loading.
The prime motive of this experimental research work is to investigate and compare the wear behaviour of aluminium (AA7075/Al–Zn–Mg–Cu) alloy metal matrix composites enriched with three different ...ceramics reinforcements (SiC/7wt%, B

C/7wt%, and porcelain/7wt%) prepared via liquid metallurgy stir casting route. Sliding wear performance for all three aluminium-ceramics matrix composites was evaluated on a pin-on-disc tribometer as per Taguchi’s L25 orthogonal array by varying normal loads, sliding velocities and sliding distances. The experimental results revealed that porcelain-reinforced composite (AA7075/7wt%porcelain) achieved better resistance property against sliding wear compared to AA7075/7wt%SiC and AA7075/7wt%B

C composites. Further, the fuzzy logic model was developed to evaluate wear loss for three composites with absolute accuracy. Finally, a metaheuristic salp swarm algorithm (SSA) was utilized to minimize wear loss for three composites. The wear loss value attained through SSA exhibits the lowest one in comparison with conventional Taguchi and fuzzy logic results.
Rice followed by wheat is the dominant cropping system in the middle Indo-Gangetic plains (IGP). Lower productivity (4.8 t ha
−1
) of this cropping system in Bihar, compared to the national average ...(6.8 t ha
−1
) due to several climate- and production-related issues, is a matter of concern for the farmers and the policymakers. Keeping all these in view, an experiment with rice–wheat cropping system was carried out during 2020–21 and 2021–22 in 17 adopted villages of 13 districts of Bihar under the Project “Climate Resilient Agriculture Program (CRAP)” to evaluate the feasibility of early transplanting of rice in the month of June with the aim of achieving higher system productivity by early harvesting of rice and subsequent timely sowing of wheat before 15 November with the provision of assured irrigation. In this study, the concept of an innovative community irrigation approach and single-phase 3-hp submersible pump was employed. Long-duration rice variety (150 days) Rajendra Mahsuri-1 was sown during 20–25 May in the nursery and transplanted through puddling operation during 15–20 June in 17 locations. Under delayed conditions, the nursery sowing and transplanting window were 10–15 June and 10–15 July, respectively. Timely sown rice grown with the provision of a community irrigation system achieved a grain yield of 5.2 t ha
−1
and 85.8% higher water productivity, compared to late-sown crops. Following the harvest of rice, the HD-2967 variety of wheat was planted in the first fortnight of November and harvested in the first week of April, yielding 4.9 t ha
−1
with the application of 2–3 irrigations based on soil type and evaporative demand. Timely harvesting of wheat facilitated farmers of the region to take an additional crop of summer green gram. With an assured irrigation system and shifting planting dates and thereby managing climatic risks, the overall productivity of the rice–wheat cropping system was achieved to the tune of 10.1 t ha

with a cropping intensity of 300% for better adaptation and sustainable production.
Introduction: The present study provides a scientific evaluation for the wound healing potential of ethanolic (EtOH) extract of Sida cordifolia Linn. (SCL) plant.
Materials and Methods: Excision, ...incision and burn wounds were inflicted upon three groups of six rats each. Group I was assigned as control (ointment base). Group II was treated with 10% EtOH extract ointment. Group III was treated with standard silver sulfadiazine (0.01%) cream. The parameters observed were percentage of wound contraction, epithelialization period, hydroxyproline content, tensile strength including histopathological studies.
Result: It was noted that the effect produced by the ethanolic extract of SCL ointment showed significant (P < 0.01) healing in all wound models when compared with the control group. All parameters such as wound contraction, epithelialization period, hydroxyproline content, tensile strength and histopathological studies showed significant (P < 0.01) changes when compared with the control.
Conclusion: The ethanolic extract ointment of SCL effectively stimulates wound contraction; increases tensile strength of excision, incision and burn wounds.
