A new biomimetic set -up to understand the role of the kinematic, mechanical, and surface characteristics of the tongue in food oral tribological studies

A biomimetic tribological set-up was developed to better integrate physiological characteristics in oral friction studies. Polyvinyl alcohol was used to design tongue-mimicking samples (TMSs) with controlled bulk rigidity and surface roughness. The set-up allowed normal stresses and sequences of shearing motion to be applied between a TMS and a rectangular aluminum plate mimicking the hard palate. Cottage cheese with and without suspended microcrystalline cellulose particles of two sizes (small: 15 mu m and large: 250 mu m) was used as the model food in the experiments, making it possible to introduce heterogeneities well above the perception threshold, which often get excluded in conventional tribology studies. The feasibility of the set-up was tested by measuring how friction coefficient values were affected by food properties (viscosity, particle presence), TMS properties (surface roughness, bulk rigidity), and operational parameters (normal stress, shearing velocity). The measurements with the set-up were found to be repeatable, confirming its reliability. Particle presence led to increases in friction coefficient values, while food viscosity showed less of an influence, comparatively. Increases in the surface roughness and bulk rigidity of the TMSs led to a pronounced augmentation of the friction coefficient values. The friction coefficient values showed dependence on normal stress, increase in normal stress led to significant decrease in friction. Moreover, friction notably increased between the lowest and highest shearing velocities. In conclusion, this set-up proved to be efficient and reliable in measuring friction coefficient values and variation, paving the way for a better understanding of oral tribology and its dynamic nature.

Indirect coal liquefaction by integrated entrained flow gasification and Rectisol/Fischer-Tropsch processes for producing automobile diesel substitutes

Herein, we describe the design and operation of an indirect coal liquefaction plant with integrated coal water slurry manufacturing, entrained flow gasification, Rectisol, and Fischer-Tropsch processes to produce liquid fuels for vehicles. The above plant contained an entrained flow gasifier (10 t/d test rig) operated using oxygen as a gasifying agent (21 bar, 1100 degrees C) and could stably produce synthesis gas (37.8 vol% H-2, 36.4 vol% CO) at 600 Nm(3)/h. Due to the importance of impurities in synthetic liquid fuel production, more than 99% of H2S contained in synthesis gas was removed by the Rectisol process employing refrigerated methanol. An iron-based catalyst allowed liquid fuels containing wax, light/heavy oil, and alcohol fractions to be obtained by the Fischer-Tropsch process at a rate of 5 barrel per day, with detailed analysis confirming their compliance with various quality standards and thus their suitability for use as automobile diesel after distillation.

Multivariate data-based optimization of membrane adsorption process for wastewater treatment: Multi-layer perceptron adaptive neural network versus adaptive neural fuzzy inference system

Application of machine-learning methods to assess the batch adsorption of malachite green (MG) dye on chitosan/polyvinyl alcohol/zeolite imidazolate frameworks membrane adsorbents (CPZ) was investigated in this study. Our previous research results proved the suitability of the CPZ membranes for wastewater decoloring. In the current work, the residence time was combined with the other operational variables i.e., pH, initial dye concentration, and adsorbent dose (AD), to obtain the possible interactions involved in nonequilibrium adsorption. Two well-known soft-computing approaches, multi-layer perceptron adaptive neural network (MLP-ANN) and adaptive neural fuzzy inference system (ANFIS), were selected among different machine learning alternatives and then, comprehensively compared with each other considering reliability and accuracy for a 60 number of runs. The ANFIS structure with nine centers of clusters could predict the adsorption performance better than the ANN approach. Root mean square error (RMSE) and R-square were obtained 0.01822 and 0.9958 for the test data, respectively. The interpretability test resulted a linear trend predicted by the model and disclosed that the maximum value of the removal efficiency (99.5%) could be obtained when the amount of the inputs set to the upper limit. Lastly, the sensitivity analysis uncovered that the residence time has a decisive effect (relevancy factor > 80%) on the removal efficiency. According to the results, ANFIS is an effective and reliable tool to optimize and intensify the membrane adsorption process. (C) 2020 Elsevier Ltd. All rights reserved.

Difficulties regulating positive and negative emotions in relation to coping motives for alcohol use and alcohol problems among hazardous drinkers

Objective: Hazardous drinking is a prevalent form of alcohol misuse. Past research has examined emotion regulation difficulties as a risk factor for hazardous drinking; however, the majority of prior studies have focused on regulation of negative emotions. Recent work has implicated difficulties regulating positive emotions in relation to alcohol misuse, yet, it is largely unknown if difficulties regulating positive emotions are significantly related to alcohol misuse outcomes after accounting for difficulties regulating negative emotions. Method: A racially diverse sample of hazardous drinkers were recruited from a university setting (75% female, M-age = 22.1, SDage = 4.0) to participate in a treatment study. Data from baseline was used in the current study. Structural equation modeling was used to evaluate relations between difficulties regulating positive and negative emotions and alcohol problems both directly and indirectly via coping motives. Results: After controlling for sex, age, and levels of negative and positive affect, positive but not negative emotion regulation difficulties were significantly associated with alcohol problems. Difficulties regulating emotions (both positive and negative), were significantly related to coping motives; each valence of difficulty was also indirectly related to alcohol problems via drinking to cope. Conclusions: Difficulties regulating emotions – both positive and negative – carry a heightened risk of engaging in coping-oriented alcohol use during drinking episodes and this maladaptive means of self regulation may explain a common pathway to experiencing alcohol-related problems. Notably, difficulties regulating positive emotions appear to offer incremental, explanatory value over and above difficulties regulating negative emotions. Such findings offer important clinical and theoretical implications.

Tailoring Multistimuli Responsive Micropatterns Activated by Various Mechanical Modes

A versatile wrinkle-based micropatterned system with a film-substrate structure is proposed, which contains a hydrophilic film of polyvinyl alcohol or its composite with laponite and a hydrophobic substrate of polydimethylsiloxane or its composite with carbon black. The wrinkled system features high design flexibility and multistimuli responsiveness, which can be activated by various mechanical methods, including vertical press or scratch, gentle stretch-and-release, bend, or analogous magneto-mechanical and electro-mechanical modes. The resultant wrinkles possess 1) instantaneous and reversible strain/moisture/light responsive optical modulation; 2) tunable dynamics for the aforementioned strain/moisture/light response;3) tailorable amplitude/wavelength; 4) unique surface morphologies from the coupling of wrinkles and cracks; 5) excellent reversibility and durability. A variety of applications are demonstrated based on this system, including 1) a moisture erasable highly sensitive pressure responsive device and pattern replicator with a high fidelity; 2) a moisture erasable scratch/magneto-mechanical re-writable tablet; 3) an electro-mechanical controllable smart window with an ultra-sensitive strain responsive transmittance modulation and a low operating voltage; 4) various types of strain responsive, moisture erasable, and laser writable information recording/encryption devices. This work provides new routes for designing innovative wrinkled systems triggered by diverse mechanical fashions and can decode multiple environmental stimuli into optical signals for widespread application.

TEMPO-oxidized cellulose fibers from wheat straw: Effect of ultrasonic pretreatment and concentration on structure and rheological properties of suspensions

Cellulose and TEMPO-oxidized cellulose fibers (TOCF) from the wheat straw were prepared with ultrasonic and chemical treatments to investigate structure and functionalities. Sol-gel transition of TOCF suspensions has been investigated using rheology to unveil the roles of ultrasonic pretreatment and temperature at various concentration. It was found that TOCF extracted with or without ultrasonic pretreatment exhibit similar functional groups in FTIR. However, different crystal structures and thermal stabilities were revealed in XRD and TGA, respectively. The gelation was independent of the ultrasonic pretreatment, while the rheological properties were highly infuenced by the concentration and temperature of the TOCF suspensions. TOCF suspensions presented a strain thinning behavior in large amplitude oscillatory shear tests. Lissajous curves showed that the elastoplastic behavior was predominantly modulated by the fiber concentration and strain amplitude other than the ultrasonic pretreatment. These results could improve the understanding of the relationships between TOCF structure and rheological properties.

A new insight of lignin pyrolysis mechanism based on functional group evolutions of solid char

To elucidate the mechanism of biomass lignin pyrolysis, the functional group evolution in lignin chars derived at 200-600 degrees C was investigated using two-dimensional perturbation correlation infrared spectroscopy, associated with the properties of the volatile products. Results from 2D-PCIS pointed that the change in the alcohol groups C-OH occurs earlier than that in the carbonyl groups C=O before 250 degrees C, corresponding to the reaction of keto-enol tautomerization: C-OH -> C=O, and the cleavage of bonds and remodeling reactions of the side chains of the benzene rings are synchronous. Besides, the formation of simple substituted benzene structures was earlier than complex substituted benzene structures. Decarbonylation, dehydrogenation and dealkylation were intensified during polycondensation of benzene rings. These findings are significant for achieving an in-depth understanding of lignin pyrolysis.

Fast-Track Liver Transplantation: Six-year Prospective Cohort Study with an Enhanced Recovery After Surgery (ERAS) Protocol

Introduction Enhanced recovery after surgery (ERAS) has been shown to facilitate discharge, decrease length of stay, improve outcomes and reduce costs. We used this concept to design a comprehensive fast-track pathway (OR-to-discharge) before starting our liver transplant activity and then applied this protocol prospectively to every patient undergoing liver transplantation at our institution, monitoring the results periodically. We now report our first six years results. Patients and methods Prospective cohort study of all the liver transplants performed at our institution for the first six years. Balanced general anesthesia, fluid restriction, thromboelastometry, inferior vena cava preservation and temporary portocaval shunt were strategies common to all cases. Standard immunosuppression administered included steroids, tacrolimus (delayed in the setting of renal impairment, with basiliximab induction added) and mycophenolate mofetil. Tacrolimus dosing was adjusted using a Bayesian estimation methodology. Oral intake and ambulation were started early. Results A total of 240 transplants were performed in 236 patients (191 male/45 female) over 74 months, mean age 56.3 +/- 9.6 years, raw MELD score 15.5 +/- 7.7. Predominant etiologies were alcohol (n = 136) and HCV (n = 82), with hepatocellular carcinoma present in 129 (54.7%). Nine patients received combined liver and kidney transplants. The mean operating time was 315 +/- 64 min with cold ischemia times of 279 +/- 88 min. Thirty-one patients (13.1%) were transfused in the OR (2.4 +/- 1.2 units of PRBC). Extubation was immediate (< 30 min) in all but four patients. Median ICU length of stay was 12.7 hours, and median post-transplant hospital stay was 4 days (2-76) with 30 patients (13.8%) going home by day 2, 87 (39.9%) by day 3, and 133 (61%) by day 4, defining our fast-track group. Thirty-day-readmission rate (34.9%) was significantly lower (28.6% vs. 44.7% p=0.015) in the fast-track group. Patient survival was 86.8% at 1 year and 78.6% at five years. Conclusion Fast-Tracking of Liver Transplant patients is feasible and can be applied as the standard of care If you are interested in 148043-73-6, you can contact me at any time and look forward to more communication.

Red yeast rice prevents chronic alcohol-induced liver disease by attenuating oxidative stress and inflammatory response in mice

Alcoholic liver disease (ALD) is characterized by dyslipidemia, hepatic steatosis, steatohepatitis, edema, necrosis, etc. Studies have reported that some dietary nutrition factors have beneficial effects in improving ALD. Red yeast rice (RYR), a traditional herbal supplement, has been confirmed to lower cholesterol mainly due to its component monacolin K. However, the effect of RYR on ALD has not been investigated. In this study, mice were supplemented with a daily oral gavage of 4 g/kg 50% ethanol for 8 weeks to induce a chronic ALD. RYR (150 mg kg(-1) day(-1)) was supplied to ALD mice in treatment group. The results showed that RYR supplementation significantly attenuated hyperlipidemia, elevated circulating inflammatory cytokines, hepatic structural damage, and oxidative stress in mice supplemented with alcohol with no effects on body weight. Moreover, RYR significantly suppressed alcohol-induced hepatic NF-kappa B activation and apoptosis. Our results suggest that RYR is capable of preventing ALD mainly by attenuating hepatic oxidative stress and inflammatory response. Practical applications RYR was known for cholesterol-lowering effect through its main component monacolin K. The current study revealed that RYR was capable of ameliorating ALD, which is characterized by profound dyslipidemia, hepatic steatosis, steatohepatitis, edema, etc. Our results indicated that the protective effect of RYR on ALD is largely achieved by regulating lipid metabolism, and closely related to the anti-inflammatory and antioxidant effects of RYR. This study provides research foundation for the development of RYR-related food or pharmaceutical products, especially targeting for ALD.

Facile electrolytic synthesis of Pt and carbon quantum dots coloaded multiwall carbon nanotube as highly efficient electrocatalyst for hydrogen evolution and ethanol oxidation

Designing high-performance Pt-based catalysts with low catalysts cost is still a great challenge. Here, we demonstrate a facile electrolysis-solvothermal technique for making Pt and carbon quantum dots coloaded multiwall carbon nanotube (Pt-CQDs/MWCNT) catalyst with the assistant of electric field. Despite of the ultralow Pt amount (0.81 wt%) for the optimized Pt-CQDs/MWCNT catalyst, it exhibits ultrahigh electroactivity and durability toward hydrogen evolution reaction (HER) and ethanol oxidation reaction (EOR). The mass activities of the catalyst for HER and EOR can be achieved to 4889.7 mA/mg (-40 mV) and 4917 mA mg; 1Pt (forward peak), which are 8.1 times and 5.6 times more active than those of commercial Pt/C respectively. The characterization results reveal that Pt nanpparticles (Pt NPs) with intrinsic structure play the key role in excellent catalytic performance for HER and EOR. CQDs not only support abundant anchoring points for fixation and dispersion of Pt NPs, but also construct 3D conductive network with MWCNT supporter for improving the catalytic performance.
