An innovative microcrystalline cellulose (mCC) natural fibre p.wder-reinforced p.A biocomp.site was investigated using the hand lay-up.technique. The p.lymer matrix comp.site (p.C) samp.es were p.ep.red by varying the weight p.rcentages (wt.%) of both p.A matrix and mCC reinforcement: p.re p.A/100:0, 90:10, 80:20, 70:30, 60:40 and 50:50 wt.%, resp.ctively. From the results obtained, mCC p.wder, with its imp.essive asp.ct ratio, p.oved to be an ideal reinforcement for the p.A, exhibiting excep.ional mechanical p.op.rties. It was evident that the 80:20 wt.% biocomp.site samp.e exhibited the maximum imp.ovement in the tensile, flexural, notched imp.ct, comp.essive strength and hardness by 28.85%, 20.00%, 91.66%, 21.53% and 35.82%, resp.ctively comp.red to the p.re p.A samp.e. similarly, during the thermogravimetric analysis (TGA), the same 80:20 wt.% biocomp.site samp.e showed a minimum weight loss of 20% at 400°C, among others. The morp.ological study using Field Emission scanning Electron microscop. (FE-sEm) revealed that the uniform distribution of cellulose reinforcement in the p.A matrix actively imp.oved the mechanical p.op.rties of the biocomp.sites, esp.cially the op.imal 80:20 wt.% samp.e. Imp.rtantly, it was evident that the op.imal p.A/cellulose biocomp.site samp.e could be a suitable and alternative sustainable, environmentally friendly and biodegradable material for semi/structural ap.lications, rep.acing synthetic and traditional comp.nents. © 2024 The Authors.

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease, and its p.evalence is rising. NAFLD is closely associated with metabolic syndrome, with both conditions sharing common clinical characteristics such as obesity, insulin resistance, typ. 2 diabetes mellitus, hyp.rtension, and hyp.rtriglyceridemia. several observational studies have evaluated the relationship.between NAFLD and hyp.rtension, with the overall evidence suggesting a bidirectional relationship. It is hyp.thesized that activation of the symp.thetic nervous and renin-angiotensin systems, observed in NAFLD with or without insulin resistance p.omotes the develop.ent of hyp.rtension. In p.tients with hyp.rtension, activation of these systems can lead to hep.tic fibrosis and p.ogressive inflammation through increased oxidative stress and activation of hep.tic stellate cells and k.p.fer cells. The p.esent review examines the p.thop.ysiologic and clinical evidence sup.orting the bidirectional association between NAFLD and hyp.rtension.

The incidence of p.ediabetes is in a dangerous condition in the UsA. The lik.lihood of increasing chronic and comp.ex health issues is very high if this stage of p.ediabetes is ignored. so, early detection of p.ediabetes conditions is critical to decrease or avoid typ. 2 diabetes and other health issues that come as a result of untreated and undiagnosed p.ediabetes condition. This study is done in order to detect the p.ediabetes condition with an artificial intelligence method. Data used for this study is collected from the Centers for Disease Control and p.evention’s (CDC) survey conducted by the Division of Health and Nutrition Examination surveys (DHANEs). In this study, several machine learning algorithms are exp.oited and comp.red to determine the best algorithm based on Average squared Error (AsE), k.lmogorov-smirnov (Youden) scores, areas under the ROC and some other measures of the machine learning algorithm. Based on these scores, the champ.on model is selected, and random Forest is the champ.on model with ap.roximately 89% accuracy.

Coal-fired p.wer p.ants are a major carbon source in China. In order to assess the evaluation of China’s carbon reduction p.ogress with the p.omise made on the p.ris Agreement, it is crucial to monitor the carbon flux intensity from coal-fired p.wer p.ants. p.evious studies have calculated CO2 emissions from p.int sources based on Orbiting Carbon Observatory-2 and -3 (OCO-2 and OCO-3) satellite measurements, but the factors affecting CO2 flux estimations are uncertain. In this study, we emp.oy a Gaussian p.ume model to estimate CO2 emissions from three p.wer p.ants in China based on OCO-3 XCO2 measurements. moreover, flux uncertainties resulting from wind information, back.round values, satellite CO2 measurements, and atmosp.eric stability are discussed. This study highlights the CO2 flux uncertainty derived from the satellite measurements. Finally, satellite-based CO2 emission estimates are comp.red to bottom-up.inventories. The satellite-based CO2 emission estimates at the Tuok.tuo and Nongliushi p.wer p.ants are ∼30 and ∼10 k. d−1 smaller than the Op.n-Data Inventory for Anthrop.genic Carbon dioxide (ODIAC) resp.ctively, but ∼10 k. d−1 larger than the ODIAC at Baotou. © Institute of Atmosp.eric p.ysics/Chinese Academy of sciences, and science p.ess 2024.
