Surface modification is an efficient post-treatment method to optimize the properties of nanofiltration (NF) membranes. Here, we report a facile surface modification strategy coupling with heat curing for grafting monoethanolamine (MEA), a monomer containing both a primary amine and a primary alcohol group, onto a nascent polyamide NF membrane. With grafting 0.5 wt% MEA at 50 degrees C, the pure water permeability of the polyamide NF membranes was improved from 7.9 to 19.5 L m(-2) h(-1) bar(-1) due to their enhanced physicochemical property, such as superior hydrophilicity, rough surface morphology, and enlarged membrane pores. Meanwhile, the rejection of Na2SO4 remained above 97.5%. More importantly, the optimal membrane modified with 0.5 wt% MEA exhibited a high Na2SO4 rejection of 99.1% and a negative NaCl rejection of -20.1% when treating a mixed salt solution containing 2 g/L Na2SO4 and 2 g/L NaCl. Our study provides a novel insight for the fabrication of high permselectivity NF membranes via surface modification.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 100442-33-9, in my other articles.

This study examines contributing variables affecting the driver injury-severity in single-vehicle roadway departure crashes. To capture the threshold heterogeneity and unobserved heterogeneity, the random thresholds random parameters hierarchical ordered pro bit (HOPIT) approach is employed using the crash data collected from 2014 to 2017 in the State of North Carolina. Three injury severity levels are considered: severe injury, minor injury, and no injury. Attributes that potentially affect crash severity are examined, including driver, crash, roadway, and environmental characteristics. A series of likelihood ratio tests are conducted to examine the temporal stability of factors across different studied years. The marginal effects of factors in different injury-severity models are compared. Significant temporal instability is found among the studied year periods. The threshold value estimated using the random threshold random parameters HOPIT model is found to be random parameters and determined by specific explanatory variables. Additionally, the effects of some factors (e.g., alcohol, curved roadway, passenger car, SUV, and wet/water surface) on injury severity are relatively stable, while others (e.g., female driver, collector, and clear weather) present temporal unstable effects. Regarding the temporal instability, decision-makers need to treat the factors carefully to avoid developing incorrect countermeasures. (C) 2020 Elsevier Ltd. All rights reserved.

Objective Older workers are increasingly prevalent in health and human services, including the alcohol and other drug (AOD) sector. Their turnover intentions have important implications for service system stability and retention. Methods Descriptive and regression analyses of survey data examined age-related differences (<50, >= 50 years old) in non-government workers’ demographic, health and professional profiles and predictors of turnover intention. Results Older workers (>= 50 years, n = 86) comprised one-third of this workforce. Compared to younger workers (n = 164), they experienced greater discrimination but higher work-life balance and work engagement. Turnover intention was predicted by job satisfaction, discrimination and work engagement. Conclusion Older workers’ well-being and workforce retention are essential for effective leadership, succession planning and service continuity. Their needs and retention motivations are identified. Age-specific support mechanisms, proactive retention and anti-discrimination strategies are identified priorities.

Objectives: Tobacco smoking and gambling disorder (GD) often co-occur. However, few studies have assessed the extent to which cigarette smoking may serve to classify and/or better define GD behaviour profiles. Methods: Among a large sample of n = 3,652 consecutive treatment-seeking patients with GD (91% men). Smokers were compared to non-smokers across different sociodemographic, clinical, psychopathological and personality variables. The effect sizes for the means and the proportion differences between the groups were estimated. An evaluation of the smoking changes over the last 15 years was also performed. Results: From the total sample, 62.4% of gamblers reported tobacco use. A decreasing linear trend in tobacco use was observed within the studied period, women having a more irregular pattern. The use of tobacco was linked to the use of alcohol and other illegal drugs. Gamblers who smoke, as compared to those who don’t, presented lower education levels, lower social position indexes and active employment. They were younger, with an earlier age of onset, shorter duration of the gambling behavior, higher GD severity, more psychological symptoms, higher scores in novelty seeking and lower scores in reward dependence, self-directedness and self-transcendence. Conclusions: Gamblers seeking treatment who smoke display particular social, clinical, psychological, temperamental and character features different from non-smoking gamblers, suggesting that the presence or absence of comorbid smoking condition in GD should always be considered when developing an optimal treatment, as gamblers who smoke might need treatment strategies different from non-smoking gamblers.

Accessible summary What is known on the subject? Relapse rates are high among patients who have experienced first-episode psychosis (FEP). Psychotic relapses are associated with worse quality of life and poorer functionality of the FEP patient. The use of psychoactive substances, non-adherence to drug treatment, and high expressed emotion (EE) are notable predictors of relapse after the FEP. Although some studies have suggested that psychotic relapse may be associated with a family environment with high levels of emotional over-involvement (EOI), this finding is still inconsistent across different cultures. EE specific components must be evaluated and interpreted according to the context of cultural norms. There is a scarcity of studies on the role of depression in the occurrence of relapses after the FEP, and the results remain uncertain. What the paper adds to existing knowledge? This study explored the predictors of psychotic relapses in Brazilian patients who experienced FEP. Our results indicate that 29.2% of the patients relapsed after the FEP. Patients diagnosed with depression and high-EOI in the family environment were predictors of psychotic relapses in this population. This study expands knowledge about the cultural specificity of EOI and the role of depression in psychotic relapse. What are the implications for practice? Nursing professionals must consider the implications of the family environment and depression in the course of psychosis. Family interventions and the appropriate treatment of depression are important for improving the prognosis of FEP patients. Introduction Psychotic relapse may be associated with relatives’ high emotional over-involvement (EOI) and with a diagnosis of major depressive episode (MDE) among first-episode psychosis (FEP) patients, but the results are still inconsistent across different cultures. Aim Evaluate the predictors of relapse in FEP patients. Method Prospective cohort study with 6-month follow-up conducted with 65 dyads of patients and relatives from an early intervention unit in Brazil. At the baseline interview, relatives answered to a sociodemographic data form and to the Family Questionnaire. Patients provided sociodemographic and clinical data and answered the Measurement of Treatment Adherence; the Alcohol, Smoking and Substance Involvement Screening Test; the Severity of Dependence Scale to assess cannabis dependence, and the MDE module of the Mini-International Neuropsychiatric Interview. Psychotic relapses were evaluated using items from the Brief Psychiatric Rating Scale. The data were analysed using multiple logistic regression. Results 29.2% of the patients presented at least one psychotic relapse. High-EOI and MDE were predictors of psychotic relapses. Discussion Our findings expand the knowledge about the cultural specificity of EOI and the role of depression in psychotic relapse. Implications for practice Family nursing interventions and the appropriate treatment of MDE must be considered in the care of FEP patients.

A magnetized zeolitic imidazolate framework (ZIF-8) impregnated with sodium hydroxide catalyst has been synthesized and tested as a new catalyst for biodiesel production. The new catalyst was investigated for the ethanolysis of vegetable oil to produce biodiesel. The operating conditions of the biodiesel production were optimized using the 2n design method followed by a reduced number of experimental runs. A 70% conversion of oil in the ethanolysis reaction was achieved using the new catalyst. The optimized operating conditions were found to be alcohol to oil molar ratio of 21:1, catalyst loading of 1% wt., a reaction time of 90 min, and temperature of 75 degrees C. Ethanolysis reaction was found to obey the pseudosecond-order kinetic model. In addition, the Arrhenius pre-exponential constant and activation energy were calculated to be 1.12 x 10(10) L mol(-1).min(1) and 77.27 kJ/mol, respectively. The physical properties of the product biodiesel matched the American Society for Testing and Materials (ASTM) ranges. Additionally, the product biodiesel achieved a Cetane number of 75, which is 15% higher than the upper range of the ASTM. (C) 2020 Elsevier Ltd. All rights reserved.

Histoplasmosis is a deep mycosis distributed worldwide and caused by Histoplasma capsulatum. Development countries and underdeveloped countries already considered an endemic disease, and its etiology comes from fungi located in soil contaminated with bird and bat droppings. Habits such as tobacco and alcohol consumption can be factors that can help to the development of disseminated histoplasmosis mainly in immunocompetent patients. Clinical manifestations can include fever, weakness, weight loss, hepatosplenomegaly, mucocutaneous lesions, and ulcer oral lesions. Oral lesions represents a commonly manifestation in the disseminated form of the disease, and it is more frequently observed in immunocompromised patients, mainly on HIV-positive patients. In this study, we presented five cases of disseminated histoplasmosis on HIVnegative patients diagnosed with lesions located in oral cavity and we performed a literature review about cases of disseminated histoplasmosis lesions in head and neck region on HIV-negative patients associating possible factors that may contribute to lesions formatting.

Substance Use Disorder (SUD) is a chronic and relapsing disease characterized by craving, loss of control, tolerance and physical dependence. At present, the combination of pharmacotherapy and psychosocial intervention is the most effective management strategy in preventing relapse to reduce dropout rates and promote abstinence in SUD patients. However, only few effective medications are available. Transcranial Magnetic Stimulation (TMS) is a non-invasive brain stimulation technique that modulates the cellular activity of the cerebral cortex through a magnetic pulse applied on selected brain areas. Recently, the efficacy of TMS has been investigated in various categories of SUD patients. The present review analyzes the application of repetitive TMS in patients with alcohol, tobacco, and cocaine use disorder. Although the number of clinical studies is still limited, repetitive TMS yields encouraging results in these patients, suggesting a possible role of TMS in the treatment of SUD.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 130198-05-9. SDS of cas: 130198-05-9.

Traditional wound dressings have some major deficiencies, including poor antibacterial ability, low exudate absorption rate and dry environment. These defects can be addressed by the prepared hydrogels in this study, which can provide a moist and cool environment for wound healing. Polyvinyl alcohol-chitosan/cerium (PVA-Cs/Ce) composite hydrogels are prepared by a freeze-thaw method and characterized by x-ray diffraction (XRD) and scanning electron microscopy (SEM). In addition, the effects of chitosan/cerium (Cs/Ce) complexes with different contents on properties, including mechanical properties, water vapor permeability, swelling ratio, and thermal stability are investigated. SEM images indicate that the composite hydrogels have a good three-dimensional pore structure. Compared with the pure PVA hydrogel, the composite hydrogels show better swelling properties and more suitable water vapor transmission rate (2504 g m(-2).day) by adding Cs/Ce complexes. And the elongation at break of the hydrogel with a ratio of 5:3 (PVA: Cs/Ce) is the highest value of 567%. In the bacteriostatic circle experiment, PVA-Cs/Ce composite hydrogels exhibit a pronounced inhibitory effect against two bacteria (Staphylococcus aureus and Escherichia coli). These results suggest that these composite hydrogels have great potential as wound dressings.

Exploring catalytic processes performed under natural conditions is interesting, but there remains a great challenge in developing highly efficient catalysts for natural oxidation of alcohols. Herein, we report a chloroplast-like catalyst comprised of photoactive carbon dots (CDs), catalytically active Pt nanoparticles, and amphiphilic nanotubes. Under simulated and real natural reaction conditions, our catalysts exhibited remarkable activity and long-term reusability for the oxidation of various alcohols, significantly outperforming that of other counterpart catalysts and reported thermal/photocatalytic systems. It was demonstrated that when the carbon dots and the amphiphilic nanotubes respectively played a role in the light-harvesting and the substrate transport the Pt/CDs heterointerface acted as the active center for the matter conversion. Such an elaborate cooperation, an advanced process in the photosynthesis of plant, contributed to the excellent catalytic performance. This contribution provides a new design concept for artificial photocatalysts, which is very promising for developing sustainable catalytic processes.

Electric Literature of 100-86-7, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 100-86-7 is helpful to your research.
