Abstract	Chicory can be used as herbal medicine against different ailments and also added to daily diet as vegetable or animal feed. An efficacy trial was conducted to assess the potential of this plant against liver disorders using rodent modeling. The trials comprised two modules i.e., normal diet and chicory-based supplemented diet. Moreover, experimental animals (rats) were divided into six groups with both modules including C

Abstract	In the present study fast dispersible nimodipine tablets were developed by direct compression method using quality by design (QbD) approach as per the central composite design by selecting avicel PH 102 (X1) and crospovidone (X2) as independent variables while % friability (R1), disintegration (R2) and hardness (R3) as output variables. Powder blends were assessed for flow characterization. At post compressional stage, several quality assessments were carried out. Particles morphology was observed using scanning electron microscopy (SEM). The stability study on the drug and optimized formulation were determined using thermal gravimetric analysis (TGA) and differential thermal analysis (DTA). RSM plots expressed the interaction of avicel PH 102 and crospovidone to determine the adequate quantities of excipients for the optimized formulation. Polynomial equations were used to validate the experimental design. The optimized formulations were evaluated for friability, disintegration and hardness. Results indicated that formulation (F4) containing avicel PH 102 (35%) and crospovidone (5%) was selected as best optimized formulation having friability 0.59%, disintegration 9 sec, % dissolution 95.703% and hardness 4.14 kg. Results of kinetics models indicated that all the developed formulations followed weibull model.

Abstract	In recent years, the scope for replacing fossil fuels has been appealing to the world, owing to limited conventional fuels, crude oil price volatility, and greenhouse gas emission concerns. In this regard, this article demonstrates the preparation of a novel solid base catalyst for the transesterification of waste cooking oil. A calcium-loaded activated carbon catalyst was prepared through pyrolysis of peach shell followed by chemical activation with KOH and then calcium loading through the wet impregnation method. The prepared catalyst showed the best performance with 20% calcium loading and 650 °C of calcination temperature. The catalyst’s physicochemical, structural, and textural properties were examined using XRD, FTIR, SEM, EDX, and BET analysis. The catalyst showed a maximum yield of 96% at optimized conditions, i.e., 65 °C temperature, oil to methanol ratio 1:8, 5 wt% catalyst concentration, and a 160 min reaction time. Additionally, it illustrated high recyclability up to 10 cycles with negligible leaching of Ca +2 ions. The high activity of the catalyst was due to the presence of calcium ions on the activated carbon support. Physio–chemical properties and GC-MS analysis of prepared biodiesel determined that all attributes were within the biodiesel standard tolerances set by ASTM D6751 and EN 14214. Therefore, all the innovations mentioned above concluded that catalyst generated from peach shell biochar is a promising candidate for biodiesel production, ultimately resulting in solid and liquid waste management.

Abstract	Microalgae demonstrate significant potential as a source of liquid-based biofuels. However, increasing biomass productivity in existing cultivation systems is a critical prerequisite for their successful integration into large-scale operations. Thus, the current work aimed to accelerate the growth of C. vulgaris via exogenous supplementation of biostimulant derived from onion peel waste. Under the optimal growth conditions, which entailed a biostimulant dosage of 37.5% v/v, a pH of 3, an air flow rate of 0.4 L/min, and a 2% v/v inoculum harvested during the mid-log phase, yielded a maximum biomass concentration of 1.865 g/L. Under the arbitrarily optimized parameters, a comparable growth pattern was evident in the upscaled cultivation of C. vulgaris, underscoring the potential commercial viability of the biostimulant. The biostimulant, characterized through gas chromatography-mass spectrometry (GC-MS) analysis, revealed a composition rich in polyphenolic and organo-sulphur compounds, notably including allyl trisulfide (28.13%), methyl allyl trisulfide (23.04%), and allyl disulfide (20.78%), showcasing potent antioxidant properties. Additionally, microalgae treated with the biostimulant consistently retained their lipid content at 18.44% without any significant reduction. Furthermore, a significant rise in saturated fatty acid (SFA) content was observed, with C16:0 and C18:1 dominating both bench-scale (44.08% and 14.01%) and upscaled (51.12% and 13.07%) microalgae cultures, in contrast to the control group where C18:2 was prevalent. Consequently, SFA contents reached 54.35% and 65.43% in bench-scale and upscaled samples respectively, compared to 33.73% in the control culture. These compositional characteristics align well with the requirements for producing high-quality crude biodiesel.

Abstract	The aim of present research work was to evaluate the Salvia macrosiphon Boiss. of Lamiaceae (mint family), using biochemical and biological assays. Plant's phytochemicals extraction was performed in methanol, butanol and water by mechanical shaking process. TPC and TFC were determined by Folin-Ciocalteu and aluminum chloride colorimetric procedures, respectively. The highest TPC (99.61±3.45 mg GAE/g) and TFC (234.72±7.12mg CE/g) were obtained in butanol and methanol, respectively. Regarding the antioxidant potential methanol extract showed the highest DPPH° scavenging potential (78.0±2.0%) and reducing activity (0.923±0.020 absorbance). The antibacterial activity of butanol extract against P. aeruginosa were found highest (ZOI = 23±2.00 mm). Antifungal study of methanol extract showed the ZOI (11 ±0.67mm) against F. brachygibbosum. The results revealed that the methanol stem extract of S. macrosiphon bear significant medicinal value and could be used for formulating phytomedicines and food preservers.

Abstract	Organizational effectiveness is contingent upon employees' contributions; however, the role of employee voice behavior as a critical component of employees' contribution to the organization has not been sufficiently acknowledged. Based on proactive behavior theory, we present a model to investigate employee voice behavior as an underlying mechanism in the relationship between supervisor delegation and perceived workplace inclusion. Using the SEM (structural equation modeling) method, we test our model's hypotheses with data from 271 employee-supervisor questionnaires administered in state-owned enterprises in the telecommunications industry. The results show that supervisor delegation is positively related to employees' promotive and prohibitive voice behavior. Promotive voice significantly influences perceived workplace inclusion, but prohibitive voice behavior was not found to have any impact on perceived workplace inclusion. Moreover, both dimensions of voice behavior, i.e., promotive and prohibitive voice behavior, significantly mediate the relationship between supervisor delegation and perceived workplace inclusion.
