Published: September 2022

Predicting crop yields is a critical issue in agricultural production optimization and intensification research. Accurate foresights of natural circumstances a year in advance can have a considerable impact on management decisions regarding crop selection, rotational location in crop rotations, agrotechnical methods employed, and long-term land use planning. One of the most important aspects of precision farming is sustainability. The novelty of this study is to evidence the effective of the temperature, pesticides, and rainfall environment parameters in the influence sustainable agriculture and economic efficiency at the farm level in Saudi Arabia. Furthermore, predicting the future values of main crop yield in Saudi Arabia. The use of artificial intelligence (AI) to estimate the impact of environment factors and agrotechnical parameters on agricultural crop yields and to anticipate yields is examined in this study. Using artificial neural networks (ANNs), a highly effective multilayer perceptron (MLP) model was built to accurately predict the crop yield, temperature, insecticides, and rainfall based on environmental data. The dataset is collected from different Saudi Arabia regions from 1994 to 2016, including the temperature, insecticides, rainfall, and crop yields for potatoes, rice, sorghum, and wheat. For this study, we relied on five different statistical evaluation metrics: the mean square error (MSE), the root-mean-square error (RMSE), normalized root mean square error (NRMSE), Pearson’s correlation coefficient (R%), and the determination coefficient (R2). Analyses of datasets for crop yields, temperature, and insecticides led to the development of the MLP models. The datasets are randomly divided into separate samples, 70% for training and 30% for testing. The best-performing MLP model is characterized by values of (R = 100%) and (R2 = 96.33) for predicting insecticides in the testing process. The temperature, insecticides, and rainfall were examined with different crop yields to confirm the effectiveness of these parameters for increasing product crop yields in Saudi Arabia; we found that these items had highest relationships. The average values are R = 98.20%, 96.50, and 99.14% with for the temperature, insecticides, and rainfall, respectively. Based on these findings, it appeared that each of the parameter categories that are considered (temperature, pesticides, and rainfall) had a similar contribution to the accuracy of anticipated yield projection.

Published: September 2022

AbstractIt has been a great challenge to effectively dye para‐aramids. This study systematically evaluated the dyeing of textile fabrics made of woven continuous filament, highly crystalline para‐aramids in supercritical carbon dioxide (ScCO2) at various combinations of temperature (T = 80–160°C) and pressure (P = 10–20 MPa), focusing on our new pretreatment method of using nonthermal plasma (NTP) to induce oil polymers on the surface of the fabrics for the enhancement of dyeing. We found that, without any pretreatment, the specific para‐aramid fabric used in this study is undyeable (dyed K/S value of ~0.5), even after an NTP surface treatment and undergoing a dyeing process in ScCO2, due to its high crystallinity and chemical inertness. Pretreating the para‐aramids with soybean oil, acrylated epoxidized soybean oil (AESO), or a mixture of soybean oil and acrylic acid (AA/Soy) followed by an NTP treatment significantly improved the dyeing color strength, as measured by K/S values up to 9.7. In these cases, AESO and AA/Soy provided comparable results, better than that obtained with soybean oil. The NTP treatment is essential in inducing a cross‐linked polymer network in situ, anchoring the para‐aramids with covalent bonds and also providing functional groups that bind the dye. The new dyeing method did not compromise the strength of the para‐aramids. Further, dyes soluble in ScCO2 should be selected, since the use of dyes insoluble in ScCO2 would require the addition of co‐solvents and other auxiliary chemicals, which complicates the downstream separation of these chemicals and decreases the benefit of ScCO2 dyeing.

Published: September 2022

AbstractSuper engineering plastics, such as polyetherimide (PEI), are widely used in various fields owing to their multifunctional properties. PEI is used in automobiles, electronics, and medicine owing to its high thermal resistance, excellent mechanical strength, flame retardancy, and chemical resistance. In this study, melt‐spun PEI filaments were thermally drawn and the effect of the drawing process conditions on their mechanical properties was investigated. To understand the mechanical properties of various forms, such as films, sheets, granules, tubes, and rods of PEI postprocessing, it is based on analyzing the behavior in one‐dimensional structures. The mechanical properties of the PEI filaments were dictated by the draw ratio, process temperature, and cooling temperature of the thermal drawing process. In addition, maintaining the drawing process temperature around the glass transition temperature (220°C) of PEI elongated the filament by up to 80%. Furthermore, the optimized cooling temperature was 150°C and draw ratio was 50%. In conclusion, PEI filaments with excellent mechanical properties were obtained by optimizing the draw ratio, process temperature, and cooling temperature of thermal drawing. Through the behavior of the molecular and crystal structures by thermal drawing of PEI filament, it is expected to be applied to two‐ or three‐dimensional structures.

Published: September 2022

AbstractIn the last decades, rigid polyurethane foam has focused on increasing renewable components and enhancing flame retardancy due to sustainable development and fire safety requirements. Herein, we report a bio‐based phosphorus‐containing polyester polyol (PMCP) that is synthesized with dimethyl methylphosphonate, malic acid, citric acid, and 1,6‐hexanediol in one pot. The hydroxyl value of PMCP is 485 ~ 512 mg KOH/g. As a result, it can be used as the sole polyol in the production of RPUF. Moreover, expandable graphite (EG) was incorporated into RPUF‐PMCP20 to enhance flame retardance. The limited oxygen index of RPUF increases from 18.3% to 24.0% with the rise in DMMP moiety in PMCP. Moreover, the peak heat release rate (PHRR) significantly decreases from 264.2 to 129 kW/m2. Meanwhile, the time to ignition increases from 5 to 18 s. The flame retardant mechanism indicated that PMCP plays a dual role in the gaseous and condensed phases. The addition of EG exhibits an excellent blocking effect. The LOI increases from 22.5% to 27.3% with increasing EG content. In addition, both the PHRR and smoke release rate of RPUF are suppressed by incorporating EG.
Comparative life cycle assessment of first‐ and second‐generation bio‐isobutene as a drop‐in substitute for fossil isobutene
Authors: Fazeni‐Fraisl Karin , Lindorfer Johannes 
Published: September 2022

AbstractIsobutene (IBN, C4H8) is widely used in industry. Currently, IBN production relies on petrochemical processes. The current work assesses the comparative environmental sustainability of bio‐based IBN production routes based on first‐ and second‐generation sugar compared with fossil IBN by applying the ISO 14044‐based Life Cycle Assessment methodology. In total nine scenarios are examined. Scenarios 1–6 used first‐generation sugar for IBN fermentation and scenarios 7–9 use cereal straw‐based second‐generation sugar. The scenarios also differ in their process energy source. The savings in Global Warming Potential for first‐generation IBN are up to 68% (scenario 1); for second‐generation IBN, the savings reach 105% if an avoided burden approach for utilizing lignin as an energy source is applied (scenario 8). It is found that applying renewable process energy is a prerequisite to maximizing greenhouse gas savings. Special attention has to be drawn to the eutrophication potential, were none of the scenarios show savings. This is driven by sugar crop cultivation owing to fertilizer usage, thermal energy from solid biomass or natural gas due to NOx emissions and nutrient use for fermentation (e.g. ammonia). Scenarios 4, 7 and 8 show savings in the acidification potential compared with fossil IBN. A driver of acidification is biomass‐based process energy generation, mainly due to SO2 and NOx emissions from biomass combustion. In contrast, all scenarios show a better environmental performance concerning the freshwater aquatic ecotoxicity potential, the abiotic depletion and the photochemical ozone creation potential. Process development should focus on conversion efficiencies and a fully renewable process energy supply. © 2022 The Authors.

Fast preparation of Eu(BTB) MOFs in dielectric barrier discharge liquid plasma for luminescent sensing of trace iron
Authors: Hou Xin , Wen Xiaohui , He Juan , Hou Xiandeng 
Published: September 2022

AbstractLanthanide metal–organic frameworks Eu(BTB) MOFs was synthesized in low‐temperature plasma produced by dielectric barrier discharge (DBD). This DBD synthesis possesses the characteristics of rapid reaction (within 20 min), mild condition (low temperature and atmospheric pressure) and simple operation compared with many traditional synthesis methods. The prepared Eu(BTB) MOF material exhibits typical red light emitting of europium (Eu3+) at 617 nm, which can selectively and sensitively be quenched in the presence of trace iron(III) ion (Fe3+). A simple, fast and sensitive fluorescence sensing strategy of Fe3+ was thus constructed, with a limit of detection (LOD) of 0.5 μM. Compared with reported fluorescence probes, Eu(BTB) MOFs have also demonstrated the advantages of low cost, easy and fast preparation, great stability, and excellent optical properties, thus making them a promising fluorescence candidate for trace Fe3+ sensing for the potential application in biological systems in the future.

AbstractAimTo evaluate how gelotophobia correlates with trait anxiety in a sample of Brazilian college students.MethodsWe evaluated the association of GELOPH < 15 > scores with both self‐reported experiences of bullying victimization and trait anxiety measures assessed by the State‐Trait Anxiety Inventory (STAI). The study consisted of a sample of 65 adult volunteers (M = 21.48, SD = 2.54 years, 38 females), recruited through social media or flyer distribution, and submitted to online versions of the gelotophobia assessment instrument (GELOPH < 15 >) and the STAI.ResultsMost participants (N = 56, 86.15%) had an STAI‐T score indicative of high trait anxiety. The average GELOPH < 15 > score of the sample was 2.69 (0.65) and 39 of the subjects (60%) were considered gelotophobes. There was a strong positive correlation between the GELOPH < 15 > and STAI‐T scores but no correlation between bullying and either the STAI‐T and GELOPH < 15 > scores. However, the great majority of subjects with gelotophobia reported been previously bullied.ConclusionIn our sample, all gelotophobes had trait anxiety, but only a fraction of anxious subjects had gelotophobia. These preliminary findings expand on previous reports underscoring the high prevalence of mental health problems afflicting higher education students in Brazil.

Published: September 2022

AbstractWe examined the direct and indirect––as mediated by job satisfaction––effects of personal life orientation on life satisfaction. We also examined whether these direct and indirect associations differed between employees working onsite or remotely. Using data from 432 employees (152 working onsite and 280 working remotely), our results revealed that personal life orientation was positively related to life satisfaction and negatively related to job satisfaction. Moreover, both of these direct associations were stronger among onsite employees than among remote employees. As a result, the indirect effects of personal life orientation on life satisfaction were significantly mediated by job satisfaction among employees working onsite, but not among employees working remotely. This study thus reveals that working remotely may act as a double‐edged sword by buffering the negative effects of personal life orientation on job satisfaction, but also by limiting the positive effects of personal life orientation on life satisfaction.

Published: September 2022

AbstractIn this study, the near infrared spectroscopy (NIRS) technology was used to quantitatively detect talcum powder in 82 wheat flour samples. Based on anomaly detection, sample division, and spectral preprocessing, four models were established to predict the content of talcum powder in wheat flour. Among them, the performance of Bayesian ridge regression (BRR) combined with second derivative (2D) was proved to be the best. In addition, 46 effective features were selected using a multilevel feature method combining improved particle swarm optimization (PSO) and genetic algorithm (GA). At this time, the coefficient of determination (R2_PRE), root mean square error of prediction (RMSEP), and relative percent difference (RPD) values of the BRR model on the prediction set reached 0.9802, 0.8914, and 6.9263. The results showed that NIRS technology was feasible in detecting the content of talcum powder in wheat flour. At the same time, the effectiveness of multilevel method was better than that of single‐level method, and the performance of improved POS was better than that of PSO.

Published: September 2022

Comprehensive SummaryEfficient synthesis of polyester polyols with tunable molecular weight and microstructures from cyclic anhydride/epoxide mixtures by taking advantage of chain transfer reaction remains a great challenge, because most of the catalysts exhibit poor tolerance to chain transfer agent (CTA). In this contribution, we demonstrated that potassium acetate (KOAc) and 18‐crown‐6 (18‐C‐6) combination has great potential in the synthesis of diverse polyester polyols with controllable molecular weight and high‐end group fidelity. Compared with KOAc, KOAc/18‐C‐6 pair could induce a much faster chain transfer between the active and dormant chains, and thus produce polyester polyols with narrow and monomodal distribution. In addition, polyester polyols could be efficiently prepared in laboratory by using commercially available cyclic anhydride without further purification (containing about 2% diacid residual as CTA) with an extremely low catalyst loading ([catalyst pair] : [anhydride] : [epoxide] = 1 : 50000 : 250000, [catalyst pair] = 0.0004 mol%). KOAc/18‐C‐6 could also promote the self‐switchable copolymerization of cyclic anhydride/epoxide/cyclic ester mixtures. Ring‐ opening copolymerization of cyclic ester was initiated automatically after the full conversion of cyclic anhydride, finally producing polyester polyols with ABA‐type block structure.

AbstractBackgroundWe recently described the tumor immune microenvironment (TIME) in oral squamous cell carcinomas (OSCC) from Sudan by assessing the core of the lesions. However, the invasive tumor front (ITF) is the most active part of OSCC lesions; thus, TIME should also be characterized at the ITF in this patient cohort.ObjectivesWe aimed to evaluate patterns of immune cell infiltration at the ITF in a cohort of OSCC patients from Sudan previously investigated at the tumor center and their association with clinicopathological parameters.MethodsThis study was performed on a prospective cohort of 22 OSCC patients attending Khartoum Dental Teaching Hospital with a median follow‐up of 48 months. Inflammatory infiltrate densities of CD4‐, CD8‐, FoxP3‐, CD20‐, CD66b‐, M1 (CD80/CD68)‐, M2 (CD163/CD68)‐, and PD‐L1‐positive cells were assessed at the ITF by immunohistochemistry, followed by digital quantitative analysis at the stromal and epithelial compartments separately. Histopathological parameters such as the worst pattern of invasion, differentiation, and tumor budding (TB) were also assessed. Correlations between clinicopathological parameters and survival analysis were investigated using SPSS.ResultsAll inflammatory cell subsets investigated were found to be higher in the stromal compartment as compared to the epithelial one, except for the PD‐L1+ subset. Stromal infiltration with the CD8+ cell subset was associated with low TB. Kaplan–Meier analyses identified higher epithelial and stromal CD4+ cell subsets. The presence of PD‐L1 was found to be associated with unfavorable overall survival. Further, Cox's regression analysis using an age‐ and tumor‐stage‐adjusted model identified epithelial PD‐L1 expression at the ITF as the only independent prognosticator.ConclusionsEpithelial PD‐L1 expression at the ITF was found to be an independent prognostic biomarker for OSCC in a cohort of Sudanese patients.

AbstractBackgroundEmerging evidence provides mechanistic insights into the pathogenesis of pulmonary fibrosis (PF), and rare anti‐PF therapeutic method has promising effect in its treatment. Rho‐associated coiled‐coil kinases (ROCK) inhibition significantly ameliorates bleomycin‐induced PF and decreases macrophage infiltration, but the mechanism remains unclear. We established bleomycin and radiation‐induced PF to identify the activity of WXWH0265, a newly designed unselective ROCK inhibitor in regulating macrophages.MethodsBleomycin‐induced PF was induced by intratracheal instillation and radiation‐induced PF was induced by bilateral thoracic irradiation. Histopathological techniques (haematoxylin and eosin, Masson's trichrome and immunohistochemistry) and hydroxyproline were used to evaluate PF severity. Western blot, quantitative real‐time reverse transcription‐polymerase chain reaction and flow cytometry were performed to explore the underlying mechanisms. Bone marrow‐derived macrophages (BMDMs) were used to verify their therapeutic effect. Clodronate liposomes were applied to deplete macrophages and to identify the therapeutic effect of WXWH0265.ResultsTherapeutic administration of ROCK inhibitor ameliorates bleomycin‐induced PF by inhibiting M2 macrophages polarisation. ROCK inhibitor showed no significant anti‐fibrotic effect in macrophages‐depleted mice. Treatment with WXWH0265 demonstrated superior protection effect in bleomycin‐induced PF compared with positive drugs. In radiation‐induced PF, ROCK inhibitor effectively ameliorated PF. Fibroblasts co‐cultured with supernatant from various M2 macrophages phenotypes revealed that M2 macrophages stimulated by interleukin‐4 promoted extracellular matrix production. Polarisation of M2 macrophages was inhibited by ROCK inhibitor treatment in vitro. The p‐signal transducer and activator of transcription 3 (STAT3) in lung tissue and BMDMs was significantly decreased in PF in vivo and vitro after treated with ROCK inhibitors.ConclusionInhibiting ROCK could significantly attenuate bleomycin‐ and radiation‐induced PF by regulating the macrophages polarisation via phosphorylation of STAT3. WXWH0265 is a kind of efficient unselective ROCK inhibitor in ameliorating PF. Furthermore, the results provide empirical evidence that ROCK inhibitor, WXWH0265 is a potential drug to prevent the development of PF.
