<div>The present study explores the performance of high-density polyethylene (HDPE) pyrooil and ethanol blends with gasoline in SI engine using statistical modeling and analysis using response surface methodology (RSM) and the Anderson–Darling (AD) residual test. The pyrooil was extracted from HDPE through pyrolysis at 450°C and then distilled to separate the liquid fraction. Two blends were prepared by combining pyrooil and gasoline, and pyrooil–ethanol mixture (volume ratio of 9:1) and gasoline, both at volumetric concentrations ranging from 2% to 8% to evaluate brake thermal efficiency (BTE) and specific fuel consumption (SFC) in a SI engine. An experimental matrix containing speed, torque, and blend ratio as independent variables for both blends were designed, analyzed, and optimized using the RSM. The results show that a 4% blend of pyrooil with gasoline (P4) and a 6% blend of pyrooil–ethanol mixture with gasoline (P6E) were optimum for an SI engine. Also, the experimental findings show that the P6E blend exhibits 11% higher BTE and 11.82% lower SFC compared to base fuel (pure gasoline), and 7.55% higher BTE and 6% lower SFC than P4. From the AD test, the residuals for BTE and SFC follow a normal distribution. The results conclude that distilled HDPE pyrooil could be used in SI engines at concentrations of P4 and P6E without requiring engine modification.</div>

The ANN are bioinspired computational models that have a broad range of applications in various engineering fields. The main objective of the present task is to build a model in order to elicit inulin from chicory through the use of ANN. Some variables that affect the inulin extraction process include the concentration of solutions, the time for extraction, the temperature of extraction, the pH of the solution and the speed of agitation. Previous studies depended on the volume of solvent, time, and temperature as experimental factor and % yield inulin as an independent variable. The outcomes show that the ANN has a 3-10-1 architecture has functions of goodness of fit to predict the inulin yield percentage. The performance of ANN is evaluated by using the evaluation index - coefficient of determination (R2). The R2 value of the ANN- predicted values inferred that inulin yield percentage fit well to the result.

Abstract Agar oligosaccharides are thought to be valuable biomolecules with high bioactivity potential, along with a wide range of applications and advantages. The current study aimed to optimize the culture parameters required to produce agarase enzyme and agar oligosaccharides from industrial waste agar. Microbacterium spp. strain SS5 was isolated from a non-marine source and could synthesize oligo derivatives for use in a variety of industries ranging from food to pharmaceuticals. In addition, the strain and culture conditions were optimized to maximize extracellular agarase production. The bacterium grew best at pH 5.0 − 9.0, with an optimal pH of 7.5 − 8.0; temperatures ranging from 25 to 45 °C, with an optimal of 35 °C; and carbon and nitrogen concentrations of 0.5% each. Plackett-Burman experimental design and response surface methods were used to optimize various process parameters for agarase production by Microbacterium spp. strain SS5. Using the Plackett-Burman experimental design, eleven process factors were screened, and agar, beef extract, CaCl2, and beginning pH were found as the most significant independent variables affecting agarase production with confidence levels above 90%. To determine the optimal concentrations of the identified process factors on agarase production, the Box- Behnken design was used. Agarase production by Microbacterium spp. strain SS5 after optimization was 0.272 U/mL, which was determined to be greater than the result obtained from the basal medium (0.132 U/mL) before screening using Plackett-Burman and BBD with a fold increase of 2.06.

AbstractThe application of cucumber peel biochar (CPB) for sorption of acid orange 7 (AO7) dye from aqueous solution has been assessed in this investigation. The adsorption process was systematically studied under different conditions including pH, exposure period, dye concentration, sorbent amount, temperature, and particle size of CPB. Maximum 96% removal of AO7 dye was observed at pH 2 by CPB with 80 mg/L AO7 dye concentration. Langmuir model appears to be the better one for experimental results description with 11.21 mg/g sorption ability. Kinetic results were well explained by pseudo‐second order model. The negative value of ΔH0 (−37.296 kJ mol−1) reflected exothermic behavior of process. CPB showed >38% adsorption ability of AO7 dye up to 5 cycles. Phytotoxic investigation showed that CPB treated AO7 dye solution enhanced growth and biochemical parameters of Triticum aestivum seeds. The seedling length and vigor index of wheat seeds showed following order: Control > AO7 dye solution treated with CPB treated > AO7 dye solution. Hence, CPB, profusely available as an agricultural waste can be applied as a cost‐effective and ecofriendly sorbent for making dye containing wastewater reusable.

COVID-2019 has been declared a Public Health Emergency of International Concern (PHEIC) by the World Health Organization due to the global spread of 2019-nCOV at an exponential rate (WHO). Scientists have hypothesized the reduction in transmission rate at warm and humid environment whereas facilitate rapid transmission at cold and dry environment. Hence in this work, we examine the combined impact of environmental and demographic factors along with the implementation of lockdown by the Government of India on the transmission rate of 2019-nCoV. Our analyses indicated a lower mortality rate in spite of higher population density in India compared to other countries and lower exponential growth factor after lockdown compared to before lockdown. The containment of transmission and mortality rate may be attributed to the favorable environment and median population age, respectively. Even though, to significantly reduce the outbreak, individuals, the media, and healthcare organizations are necessary to work together. © 2023 Author(s).

AbstractThis study assessed the sorption ability of orange peel biochar (OPB) for the removal of Basic Red 46 (BR46) dye. Batch trials were conducted to examine the effects of pH, time, initial dye concentration, dosage, temperature, and particle size on BR46 removal from aqueous solution. Maximum removal by OPB of 94 % was observed at pH 9 and an initial dye concentration of 100 mg L−1. The surface morphology of OPB was characterized by scanning electron microscopy. Equilibrium data were well fitted to the Langmuir model with maximum sorption capacity of 7.36 mg g−1. Adsorption kinetics and thermodynamics revealed a pseudo‐second‐order mechanism, chemisorption, and an exothermic process. Phytotoxicity studies revealed that OPB‐treated effluent can be used for irrigation. Thus, OPB could be a potential adsorbent for BR46 removal.
