This study’s aim was to determine the pesticide residues in 10 different vegetable commodities from the Asir region, Saudi Arabia. We evaluated 211 vegetable samples, collected from supermarkets between March 2018 and September 2018, for a total of 80 different pesticides using ultrahigh-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) and gas chromatography-tandem mass spectrometry (GC-MS/MS) after extraction with a multi-residue method (the QuEChERS method). The results were assessed according to the maximum residue limit (MRL) provided by European regulations for each pesticide in each commodity. All lettuce, cauliflower, and carrot samples were found to be free from pesticide residues. A total of 145 samples (68.7%) contained detectable pesticide residues at or lower than MRLs, and 44 samples (20.9%) contained detectable pesticide residues above MRLs. MRL values were exceeded most often in chili pepper (14 samples) and cucumber (10 samples). Methomyl, imidacloprid, metalaxyl, and cyproconazole were the most frequently detected pesticides. Based on the results of this study, we recommend that a government-supported program for the monitoring of pesticide residues in vegetables be established to promote consumers’ health and achieve sustainable farming systems.

An article Synthesis of glycolurils and hydantoins by reaction of urea and 1,2-dicarbonylcompounds using etidronic acid as a green catalyst WOS:000571595400001 published article about CRYSTAL-STRUCTURE; MODULAR APPROACH; DERIVATIVES; CUCURBITURIL in [Bakibaev, Abdigali A.; Uhov, Artur; Malkov, Victor S.; Panshina, Svetlana Yu.] Natl Res Tomsk State Univ, Dept Chem, Tomsk 634050, Russia; [Panshina, Svetlana Yu.] Natl Res Tomsk Polytech Univ, Dept Chem, Tomsk, Russia in 2020.0, Cited 52.0.

Most of the known methods for the synthesis of heterocyclic compounds have disadvantages, such as a long reaction time and aggressive conditions. We have developed a new, rather simple and efficient method for the synthesis of a number of glycoluryls and hydantoins in water using a etidronic acid (HEDP) as Green catalyst. So, for the first time, the condensation reaction of ureas with 1, 2-dicarbonyl compounds was carried out in the presence of HEDP. Also based on NMR studies, a chemism of these reactions, which is stepwise, is proposed. It has been established that the optimal conditions for the synthesis of glycoluryls and hydantoins using HEDP are: temperature 80 degrees C-90 degrees C, 40-20 minutes, and the ratio of urea and HEDP is 1:1. In all cases, the remaining aqueous filtrate containing HEDP after the reaction can be reused for other cycles synthesis of glycoluril and other compounds, because HEDP is not converted during the reaction.

The thermochemical network of 91 isodesmic and other balanced reactions was used to adjust simultaneously the enthalpies of formation of 14 urea compounds. The experimental enthalpies of formation of these compounds were treated as unknowns in the least-squares minimization of deviations between the theoretically predicted enthalpies of reaction and experimental values. A result of a least-squares fit confirms the accuracy of experimental enthalpies of formation of 8 ureas, whereas the experimental measurements for 6 urea compounds require re-examination. The gas-phase standard enthalpies of formation of 8 ureas were used as a consistent basis to obtain values for other 15 ureas through isodesmic reactions. To estimate the enthalpies of formation in crystalline state, the sublimation enthalpies were predicted using the molecular electrostatic potential model. (C) 2018 Elsevier Ltd.

Pure organic room-temperature phosphorescence (RTP) and luminescence from nonconventional luminophores have gained increasing attention. However, it remains challenging to achieve efficient RTP from unorthodox luminophores, on account of the unsophisticated understanding of the emission mechanism. Herein, we propose a strategy to realize efficient RTP in nonconventional luminophores through incorporation of lone pairs together with clustering and effective electronic interactions. The former promotes spin-orbit coupling and boosts the consequent intersystem crossing, whereas the latter narrows energy gaps and stabilizes the triplets, thus synergistically affording remarkable RTP. Experimental and theoretical results of urea and its derivatives verify the design rationale. Remarkably, RTP from thiourea solids with unprecedentedly high efficiency of up to 24.5 % is obtained. Further control experiments testify the crucial role of through-space delocalization on the emission. These results will spur the future fabrication of nonconventional phosphors and advance the understanding of the underlying emission mechanism.

The abiotic photochemical reactions that take place naturally in sunlit surface waters can degrade many contaminants that pose concern to water bodies for their potentially toxic and long-term effects. This works aims at assessing the ability of European rivers to photoproduce reactive transient intermediates, such as HO center dot radicals and the excited triplet states of chromophoric dissolved organic matter ((CDOM)-C-3*), involved in pollutant degradation. A photochemical mapping of the steady-state concentrations of these transients was carried out by means of a suitable modeling tool, in the latitude belt between 40 and 50 degrees N. Such a map allowed for the prediction of the photochemical lifetimes of the phenylurea herbicide isoproturon (mostly undergoing photodegradation upon reaction with HO center dot and especially (CDOM)-C-3*) across different European countries. For some rivers, a more extensive dataset was available spanning the years 1990-2002, which allowed for the computation of the steady-state concentration of the carbonate radicals (CO3 center dot-). With these data, it was possible to assess the time trends of the photochemical half-lives of further contaminants (atrazine, ibuprofen, carbamazepine, and clofibric acid). The calculated lifetimes were in the range of days to weeks, which might or might not allow for efficient depollution depending on the river-water flow velocity.

This study reports an innovative pathway for successfully synthesizing composite panels using various waste input. For this purpose, seven types of powder from waste or widely available filler i.e. Quartz off-cut, sand, waste seashell, dolomite, limestone aggregates, concrete waste and limestone dust were used. The study aims to assess the effectiveness and mechanical properties of the various waste powder in the production of powder-resin composites. The panels were then compared with the novel polymeric glass composite (PGC) in the previous study (Heriyanto et al., 2018). Following the same procedure in PGC, the filler was individually grounded to 64-108 mu m and chemically treated with amino silane coupling agent (CA). The powder filler (untreated or treated) is then mixed with the resin binder with a ratio of 80/20 respectively, followed by hot pressing the mixture at the pressure of 550 bar at 65 degrees C for 1 h. The final composite slab is then further cut for mechanical testing. It was found in the study that when CA was not added, surface roughness of the powder particles affected the flexural strength of the final panel significantly. High surface roughness particles such as in Quartz, sand and seashell adhere effectively with the resin binder which led to higher strength. On the contrary, other factors like smooth particle morphology in glass, dolomite and limestone as well as porous structure in concrete and clump of very fine powder in limestone dust degrade the strength of the final panels. With CA addition, adhesion between resin and powder filler were improved significantly. Flexural strength after the CA treatment was found to be much affected by particle characteristics. Silica-based panels i.e. quartz, sand and glass which consist of high strength and hardness of silica particles perform better compared to that of calcium carbonate-based panels. Compression strength, toughness, stiffness, scratch resistance, density and water absorption were also reported in this study. The properties of all the treated panels are found to be comparable, or if not, much better than natural stones. These new approaches of using waste filler in powder – resin based composites can be a new alternative to produce green materials that deliver economic and environmental benefits.

Magnetic porous microspheres composed of Fe3C, MnO and graphitic carbon (Fe3C/MnO/GC) were prepared by a one-pot method. A polycondensate obtained from urea and formaldehyde served as the carbon source and was calcined in the presence of metallic iron and manganese to yield Fe3C/MnO/GC. The resultant hybrid has highly mesoporous architecture, large specific surface, graphitic structure and adequate saturation magnetism. It is shown to possess excellent pre-concentration ability for herbicides (monuron, chlortoluron, atrazine and terbutylhylazine). The sorbent can be easily separated and has a long service lifetime (>25cycles). Under optimized conditions, the sorbent excels by good recoveries (78-120%), high enrichment factors (45-50) and good precision (RSDs <= 10.7%). The limits of detection are 0.01-0.10 gL(-1) for (spiked) water samples, 0.22-0.87 mu g kg(-1) for grape samples, and 0.18-0.74 mu g kg(-1) for potato samples. This work offers a new strategy for the construction of magnetic bimetallic heterostructured GC hybrids. Formula: C7H8N2O.

OBJECTIVE In patients with type 2 diabetes uncontrolled with metformin, exenatide once weekly (QW) plus dapagliflozin produced greater reductions in glycemic parameters (glycated hemoglobin [HbA(1c)], fasting plasma glucose [FPG], and 2-h postprandial glucose [2-h PPG]), weight, and systolic blood pressure (SBP) than exenatide QW or dapagliflozin alone after 28 weeks of treatment in DURATION-8. Following a 24-week extension period, improvements were sustained at 52 weeks. In this study, we investigated efficacy and safety at 104 weeks after randomization. RESEARCH DESIGN AND METHODS DURATION-8 was a 104-week, multicenter, double-blind, randomized, active-controlled, phase 3 trial. In total, 695 adults (aged >= 18 years) with type 2 diabetes and inadequate glycemic control (HbA(1c)8.0-12.0% [64-108 mmol/mol]) despite stable metformin monotherapy (>= 1,500 mg/day) were randomly assigned (1:1:1) to receive exenatide 2 mg QW plus once-daily dapagliflozin 10 mg, exenatide QW plus placebo, or dapagliflozin plus placebo. All 104-week evaluations were exploratory. RESULTS At week 104, 431 (62.0%) patients completed treatment. The adjusted least squares mean change (SE) from baseline to week 104 in HbA(1c)was greater with exenatide QW plus dapagliflozin (-1.70% [0.11]) versus exenatide QW plus placebo (-1.29% [0.12];P= 0.007) and dapagliflozin plus placebo (-1.06% [0.12];P< 0.001). Clinically relevant changes in FPG, 2-h PPG, weight, and SBP were also observed with exenatide QW plus dapagliflozin. There were no unexpected safety findings, and exenatide QW plus dapagliflozin was well tolerated, with no episodes of major hypoglycemia. CONCLUSIONS In this exploratory analysis, among those individuals who completed the trial without rescue therapy, there was clinically relevant efficacy over 2 years with exenatide QW plus dapagliflozin, with no unexpected safety findings.
