MHD Flow of Fractionalized Jeffrey Fluid with Newtonian Heating and Thermal Radiation Over a Vertical Plate

The objective of this paper is to analyze the influence of heat absorption/generation and mass diffusion on magnetohydrodynamics(MHD) Jeffrey fluid flow over a perpendicular plate moving exponentially immersed in a porous media. The Newtonian heating condition are udes for the fluid motion. The impact of thermal radiation is used in the energy equation. The two types of magnetic field have been evaluated. The main purpose of present work is to acquire the analytical solution with the help of Atangana-Baleanu (AB), Caputo, and Caputo-Fabrizio fractional derivatives. We have drawn a graphical comparison between the solutions of these three types of fractional models of jeffery fluid. Graphs of different parameters have been also plotted using MathCad software. Furthermore, comparison among ordinary and fractionalized velocity fields are made to observe the impact of fractional parameter . It is clear from graph that velocity obtained with ordinary derivative is higher than that obtained with fractional derivatives. It is also found that velocity obtained with Atangana-Baleanu (AB) fractional derivative is smaller than that obtained with Caputo and Caputo-Fabrizio fractional derivatives. Therefore, Atangana-Baleanu fractional derivative is the best choice to obtain controlled velocity

Biocompatibility and Physiological Thiolytic Degradability of Radically Made Thioester-Functional Copolymers: Opportunities for Drug Release

Being nondegradable, vinyl polymers have limited biomedical applicability. Unfortunately, backbone esters incorporated through conventional radical ring-opening methods do not undergo appreciable abiotic hydrolysis under physiologically relevant conditions. Here, PEG acrylate and di(ethylene glycol) acrylamide-based copolymers containing backbone thioesters were prepared through the radical ring-opening copolymerization of the thionolactone dibenzo[c,e]oxepin-5(7H)-thione. The thioesters degraded fully in the presence of 10 mM cysteine at pH 7.4, with the mechanism presumed to involve an irreversible S–N switch. Degradations with N-acetylcysteine and glutathione were reversible through the thiol–thioester exchange polycondensation of R–SC(═O)–polymer–SH fragments with full degradation relying on an increased thiolate/thioester ratio. Treatment with 10 mM glutathione at pH 7.2 (mimicking intracellular conditions) triggered an insoluble–soluble switch of a temperature-responsive copolymer at 37 °C and the release of encapsulated Nile Red (as a drug model) from core-degradable diblock copolymer micelles. Copolymers and their cysteinolytic degradation products were found to be noncytotoxic, making thioester backbone-functional polymers promising for drug delivery applications

Assessing suboptimal health status in the Saudi population: Translation and validation of the SHSQ-25 questionnaire

Background: Suboptimal Health Status (SHS) is realised as a vital feature for improving global health. However, the Arabian world does not have a validated instrument for screening SHS in their population. Therefore, the study aimed to evaluate the psychometric properties of Arabic-translated SHS (ASHSQ-25) in the Saudi Arabian population. Methods: We conducted a cross-sectional study among the conveniently sampled 1590 participants from the Saudi population (with a 97.4% response rate). The data was gathered through an online survey and then exported into SPSS and AMOS version 26.0 for analysis. Mann-Whitney and Kruskal-Wallis tests were used to identify the median difference between demographic groups. The one-tailed 90% upper limit of SHS scores was chosen as the cut-off criteria for SHS. Reliability and confirmatory analysis were performed for the psychometric evaluation of ASHSQ-25 in the Saudi Arabian context. Results: This study demonstrates that the ASHSQ-25 has good internal consistency, interclass correlation coefficient (ICC) = 0.92; 95% confidence interval (CI) = 0.91-0.93) and reliability (Cronbach\u27s α = 0.92). The confirmatory factor analysis (CFA) results indicated a good fit of the databased on the CMIN/degrees of freedom (df) = 4.461, comparative fit index (CFI) = 0.94, Tucker Lewis index (TLI) = 0.93, and Root Mean Square Error of Approximation (RMSEA) = 0.05. The result factor loadings for each item were high ( ≥ 0.55), except for one item from the immune system subscale. The SHS cut-off point for ASHSQ-25 was 33, leading to a 23.7% prevalence of SHS. Conclusions: This study reveals that ASHSQ-25 has appropriate internal consistency and structural validity to assess SHS in an Arabic-speaking population; therefore, it is recommended

Pastoralism in Changthang, Ladakh: Adaptations, Challenges, and Pathways for Sustainability

In the Changthang region of Ladakh, India, pastoralism serves as the cornerstone of both the local economy and the local way of life. However, recent socioeconomic shifts and environmental constraints put this economic structure, which has been expertly adapted to the difficult trans-Himalayan geography, in danger of becoming unsustainable. To explore methods for balancing development, ecology, and Indigenous culture, this review analyzes pastoralism in Changthang. The sole dependable method of food production for generations has been mobile pastoralism, supported by high-elevation rangelands. Breeds of native livestock adapted to scant vegetation and seasonal variation have been selectively bred by generations of pastoralists. Sale of wool and cashmere provides financial stability for pastoralist families, mitigating income vulnerability to climate shocks and market fluctuations that would otherwise disrupt predominantly livestock-rearing livelihoods. However, traditional transhumance cycles and collective resource management have been hampered by sedentarization, population growth, conservation constraints, and market integration. Climate change and unrestricted grazing contribute to grassland degradation. Promising programs combine conventional methods with innovations like mobile veterinary services and satellite forecasting to preserve breeds and grazing resources while increasing productivity and climate resilience. These initiatives seek to support regulated grazing practices. Comanagement practices that involve communities in conservation planning are essential. This production system and culture can be maintained through integrated strategies respecting pastoralists' stewardship

Effect of foliar application of nano-nutrients solution on growth and biochemical attributes of tomato (Solanum lycopersicum) under drought stress

IntroductionDrought stress has drastically hampered the growth and yield of many crops. Therefore, environmentally safe agricultural techniques are needed to mitigate drought stress impact. To this end, foliar spray of nano-nutrients solution to (NNS) alleviate harmful aspects of drought stress.MethodsIn a completely randomized design (CRD) experiment, seedlings were transplanted into pots at 2-3 leaf stage, each filled with loam-compost- organic manure soil (3:1:1). Plants were divided into two groups. (a) control group (b) applied stress group. Plants at vegetative stage were treated with 100% FC for control group and 60% FC for drought group, and these levels were maintained until harvesting. Three treatments of NNS with four levels i.e., 0%, 1%, 3% and 5% were given to all the pots after two weeks of drought stress treatment with a gap of 5 days at vegetative stage.Results and discussionApplication of 1% of nano-nutrient solution displayed an improvement in shoot length, shoot fresh and dry weight, number of leaves and flowers. Leaf chlorophylls and carotenoids and total phenolics contents were found maximum while minimum electrolyte leakage was observed at 3% application compared to control. Further, 1% application of NNS increased the Leaf RWC%, total soluble sugars, flavonoids contents. 5% NNS application exhibited higher total free amino acids with minimum lipid peroxidation rate in leaves of tomato under drought. Antioxidant enzyme activities increased in a concentration dependent manner as gradual increase was observed at 1%, 3% and 5%, respectively. Overall, this study introduced a new insights on using nano-nutrient solutions to maintain natural resources and ensure agricultural sustainabilit

Effect of Dietary Cation Anion Difference on Buffalo Performance during Summer

Influence of -110, +110, +220 and +330 mEq/kg dry matter (DM) of dietary cation anion difference (DCAD) on performance of early lactating Nili Ravi buffaloes was examined in a randomized complete block design during summer. Four DCAD levels were randomly allotted to four groups, three buffaloes in each group. A linear increase in nutrients and water intakes were recorded with increasing the DCAD level. A significant increase in blood pH and HCO3 was noticed with increasing DCAD level. Serum (Na + K) - (Cl + S) increased linearly with increasing the DCAD level while high serum chloride was noticed in buffaloes fed -110 DCAD diet. The serum calcium increased significantly with decreasing the DCAD level while serum magnesium and phosphorus remained unaffected. Urine pH increased significantly with increasing DCAD level. Higher serum cortisol was notices in buffaloes fed -110 than those fed +330 mEq/kg. A linear increase in milk yield was also noticed with increasing the DCAD level. Milk fat% increased significantly with increasing the DCAD while all other milk constituents remained unaltered. Buffaloes fed high DCAD diets had higher conception rate and less services per conception than those fed low DCAD diets
