A „zöld” metanol szerepe a fenntartható energiagazdálkodásban
Authors: Tóth Judit , Magda Robert
Published: November 2019

A globális energiaigény folyamatosan növekszik, így az emberiség jövője szempontjából kiemelkedő jelentőséggel bír, hogy milyen energiaforrásokat használunk fel, milyen az energia felhasználás hatékonysága. A természeti erőforrások fenntartható módon történő hasznosításában, a fosszilis, kőolaj központú energiarendszerről való hatékony és zökkenőmentes áttérésben, az üvegházhatású gázok kibocsátásának csökkentésében a metanol kulcsszerepet tölthet be. A hosszú távú gondolkodás a megújuló energiaforrások felhasználásának bővülését eredményezi, amely kedvez a zöldmetanol-technológia terjedésének, s ezáltal egy szénsemleges üzemanyag használatának. A zöldmetanol-gyártás alapanyaga lehet szilárd települési hulladék, mezőgazdasági hulladék, szén-dioxid valamint megújuló hidrogén, s a metanolnak számos felhasználása van, mind üzemanyagként, mind kémiai alapanyagként. További lehetőséget nyújt az időszakos forrásokból származó megújuló energia feleslegének kémiai tárolására, ezáltal csökkentve a fosszilis üzemanyagoktól való függőséget. A zöld metanol gazdaságos előállíthatóságának legfőbb meghatározója az elektrolízishez alkalmazott villamos energia ára, így a szén- dioxidból kiinduló gyártás versenyképességét nagyban elősegíti a nap- és szélenergia árának csökkenése.

Published: November 2019

A stationary and mobile device based on a low-cost dust sensor (Plantower PMS7003) was used to study particulate matter (PM) concentration in Miskolc. The stationary device was placed at the automatic monitoring station of the National Air Quality Measurement Network (OLM) in Martintelep, Miskolc. The mobile device was used to walk 4 streets along a square route with a total length of 800 m. Measurements were made on two days (September 9 and 11) between 7am and 9am, which according to preliminary experience coincided with the morning rush hour. The access route includes the OLM monitoring station, a busy road, two bypasses, a parking lot, and a smaller roadway blocked by traffic. The measured PM1, PM2.5, PM10 concentrations of the mobile device were interpolated on a circuit-by-circuit basis in ArcGIS, and conclusions were drawn for the area. The concentration of stationary and mobile devices was compared.

What College Students Post About Depression on Facebook and the Support They Perceive: Content Analysis
Authors: Cash Scottye , Schwab-Reese Laura Marie , Zipfel Erin , Wilt Megan , Moreno Megan
Published: November 2019

Background

College students frequently use social media sites to connect with friends. Increasingly, research suggests college students and other young adults seek mental health-related support on social media, which may present a unique venue for intervention.

Objective

The purpose of this study was to examine college students’ perceptions about displaying feelings of depression on Facebook and, in turn, how their social media friends responded.

Methods

A primarily quantitative online survey with open response questions was distributed to students at four US universities. Qualitative responses were analyzed using content analysis.

Results

A total of 34 students provided qualitative responses for analysis, these students were 85.3% female, mean age 20.2 (SD=1.4) and 20.6% racial/ethnic minority. Students who reported posting about depression often expressed an emotion or feeling but did not use the word “depression” in the post. Approximately 20% posted language about a bad day, and 15% posted a song or music video. Only one person reported posting a statement that directly asked for help. When friends responded to the posts, students generally perceived the responses as supportive or motivating gestures. Nearly 15% of friends contacted the individual outside of Facebook. One individual received a negative response and no responses suggested that the individual seek help.

Conclusions

This study found that college students who post about depression often do so without directly referencing depression and that friends were generally supportive. However, no participants reported their social network suggested they seek help, which may suggest increasing mental health literacy, for both support seekers and responders, would be an opportunity to improve online mental health-related support.
Mediators of Intervention Effects on Depressive Symptoms Among People Living With HIV: Secondary Analysis of a Mobile Health Randomized Controlled Trial Using Latent Growth Curve Modeling
Authors: Zhu Mengting , Cai Weiping , Li Linghua , Guo Yan , Monroe-Wise Aliza , Li Yiran , Zeng Chengbo , Qiao Jiaying , Xu Zhimeng , Zhang Hanxi , Zeng Yu , Liu Cong
Published: November 2019

Background

Although several studies have investigated the effects of mobile health (mHealth) interventions on depression among people living with HIV, few studies have explored mediators of mHealth-based interventions to improve mental health in people living with HIV. Identifying influential mediators may enhance and refine effective components of mHealth interventions to improve mental health of people living with HIV.

Objective

This study aimed to examine mediating factors of the effects of a mHealth intervention, Run4Love, designed to reduce depression among people living with HIV using 4 time-point measurement data.

Methods

This study used data from a randomized controlled trial of a mHealth intervention among people living with HIV with elevated depressive symptoms in Guangzhou, China. A total of 300 patients were assigned to receive either the mHealth intervention (n=150) or a waitlist control group (n=150) through computer-generated block randomization. Depressive symptoms, coping, and HIV-related stigma were measured at baseline, 3-, 6-, and 9-month follow-ups. The latent growth curve model was used to examine the effects of the intervention on depressive symptoms via potential mediators. Mediating effects were estimated using bias-corrected 95% bootstrapped CIs (BCIs) with resampling of 5000.

Results

Enhanced positive coping and reduced HIV-related stigma served as effective treatment mediators in the mHealth intervention. Specially, there was a significant indirect effect of the mHealth intervention on the slope of depressive symptoms via the slope of positive coping (beta=–2.86; 95% BCI –4.78 to –0.94). The indirect effect of the mHealth intervention on the slope of depressive symptoms via the slope of HIV-related stigma was also statistically significant (beta=–1.71; 95% BCI –3.03 to –0.40). These findings indicated that enhancement of positive coping and reduction of HIV-related stigma were important mediating factors of the mHealth intervention in reducing depression among people living with HIV.

Conclusions

This study revealed the underlying mediators of a mHealth intervention to reduce depression among people living with HIV using latent growth curve model and 4 time-point longitudinal measurement data. The study results underscored the importance of improving positive coping skills and mitigating HIV-related stigma in mHealth interventions to reduce depression among people living with HIV.
Acceptability and Effectiveness of NHS-Recommended e-Therapies for Depression, Anxiety, and Stress: Meta-Analysis (Preprint)
Authors: Simmonds-Buckley Melanie , Bennion Matthew Russell , Kellett Stephen , Millings Abigail , Hardy Gillian E , Moore Roger K
Published: November 2019

BACKGROUND

There is a disconnect between the ability to swiftly develop e-therapies for the treatment of depression, anxiety, and stress, and the scrupulous evaluation of their clinical utility. This creates a risk that the e-therapies routinely provided within publicly funded psychological health care have evaded appropriate rigorous evaluation in their development.

OBJECTIVE

This study aims to conduct a meta-analytic review of the gold standard evidence of the acceptability and clinical effectiveness of e-therapies recommended for use in the National Health Service (NHS) in the United Kingdom.

METHODS

Systematic searches identified appropriate randomized controlled trials (RCTs). Depression, anxiety, and stress outcomes at the end of treatment and follow-up were synthesized using a random-effects meta-analysis. The grading of recommendations assessment, development, and evaluation approach was used to assess the quality of each meta-analytic comparison. Moderators of treatment effect were examined using subgroup and meta-regression analysis. Dropout rates for e-therapies (as a proxy for acceptability) were compared against controls.

RESULTS

A total of 24 studies evaluating 7 of 48 NHS-recommended e-therapies were qualitatively and quantitatively synthesized. Depression, anxiety, and stress outcomes for e-therapies were superior to controls (depression: standardized mean difference [SMD] 0.38, 95% CI 0.24 to 0.52, N=7075; anxiety and stress: SMD 0.43, 95% CI 0.24 to 0.63, n=4863), and these small effects were maintained at follow-up. Average dropout rates for e-therapies (31%, SD 17.35) were significantly higher than those of controls (17%, SD 13.31). Limited moderators of the treatment effect were found.

CONCLUSIONS

Many NHS-recommended e-therapies have not been through an RCT-style evaluation. The e-therapies that have been appropriately evaluated generate small but significant, durable, beneficial treatment effects.

A Synergistic Sensitized Fluorescent Determination of 2,4-Dichlorophenoxyacetic Acid in Vegetable Samples Based on the Derivatives of Calix[4]arene
Authors: Zhu Xiashi , Ren Qiuyi
Published: November 2019

A novel fluorescent determination of 2,4-dichlorophenoxyacetic acid (2,4-D) based on the derivatives of calix[4]arene (SAX) in ?-cyclodextrin(?-CD)/ sodium dodecyl sulfate (SDS) synergistic sensitized system was developed. The results were shown that the fluorescence intensity of SAX could be quenched by 2,4-D, and the fluorescence quenching (?F=FSAX-F2,4-D -SAX) was synergistic sensitized in ?-CD/ SDS medium. Under the conditions of ?ex/em=332/468 nm and pH 7.0, the linear range for 2,4-D were found to be 0.020-4.00 ?g/mL. The mechanism of determination was discussed with quenching type analysis, inclusion interaction and sensitizing effect. This method has been applied for the determination of 2,4-D in vegetable samples with satisfactory results.

Authors: AGUSLINA KIRTISHANTI  , RIDHO ISLAMIE
Published: November 2019

Objective: The objective of the study was to evaluate the subchronic toxicity of Sauropus androgynus L. Merr. leaves soup.

Methods: Subchronic oral toxicity tests were carried out for 28 days in female Wistar rats using conventional methods. Thirty rats were divided into six groups, namely, one control group and three test groups with each extract being given at a dose of 500 mg/kg body weight (BW), 1000 mg/kg BW, and 3000 mg/kg BW, and one group satellite control and satellite test group with doses of 3000 mg/kg BW were carried out for 14 days after 28 days of treatment to see the effects of reversibility. All rat groups were observed for behavior, development of BW, serum glutamic pyruvic transaminase (SGPT), serum glutamic oxaloacetic transaminase (SGOT), creatinine serum, ratio of liver and lung organs to BW, and histology of liver and lung.

Results: The macroscopic observation of rat’s lung and rat weight ratio did not show a significant difference to the control group (p>0.05). In addition, the ratio of liver volume to BW was significantly different between the doses of 1000 mg/kg BW and 3000 mg/kg BW with satellite groups 3000 mg/kg BW (p<0.05). Levels of SGOT and SGPT as well as liver and lung histopathology scores did not show a significant difference to the control group (p>0.05). However, creatinine serum had the highest increase at a dose of 500 mg/kg BW and a dose of 1000 mg/kg BW. Reversibility effects were not seen after 14 days of the past day given Sauropus androgynous soup for 28 days in female Wistar rats.

Conclusion: The given of S. androgynous soup for 28 days for female Wistar rats did not show any specific toxicity effect so that its use was relatively safe for the consumption under 30 days. This study is expected to be the information source about the safety profile of S. androgynus leaves soup consumption.

Objective: The present study aimed to develop a novel type of superparamagnetic iron oxide nanoparticles (SPIONs) to deliver prednisolone at colon as a target site for the treatment of inflammatory bowel disease (IBD) such as ulcerative colitis and Crohn’s disease which may further progress to cancer.

Methods: SPIONs were synthesized using a coprecipitation method. Further, it was encapsulated with prednisolone-polyethylene glycol by double emulsion method (W1/O/W2). The prepared formulations were characterized for its physicochemical characterization such as scanning electron microscopy, X-ray diffraction, particle size and zeta potential, encapsulation efficiency, and in vitro drug release.

Results: The results reveal that the physicochemical property of the formulations complies with the standard values and in vitro release of prednisolone in the first 18 h, attains 57 and 58% and it reaches 71 and 75% at 24 h, and this is statistically significant (p˂0.0177). This release result implies that the drug release from the formulations is controllable and sustains manner.

Conclusion: Our findings could be a promising approach for the delivery of prednisolone with enhanced half-life for the treatment of IBD through colon targeting.

Published: November 2019

Aim:
To compare hospital mortality in patients with aspiration-associated pneumonia treated with ceftriaxone (CTRX) and in those treated with ampicillin/sulbactam (ABPC/SBT).
Methods:
From a Japanese multicentre observational study cohort of patients with pneumonia, those diagnosed with pneumonia and having at least one aspiration-related risk factor were selected. Propensity score-matching analysis was used to balance baseline characteristics of the participants and compare hospital mortality of patients treated with CTRX and those treated with ABPC/SBT.
Results:
Hospital mortality did not significantly differ between patients treated with CTRX and those treated with ABPC/SBT (6.6 vs 10.7%, risk difference -4.0, 95% CI [-9.4, 1.3]; p = 0.143).
Conclusion:
Further studies are needed to compare CTRX and ABPC/SBT treatments in patients with aspiration-associated pneumonia.
Phylogenetic analysis of stemmed points from Patagonia: Shape change and morphospace evolution
Authors: Cardillo Marcelo , Charlin Judith
Published: November 2019

This work is focused in the study of Patagonian lithic projectile points shape variation from a phylogenetic perspective pursuing three main aims: first, generate a model of projectile point shape diversification and morphospace evolution; second, estimate shape variation through time, and finally, assess the robustness of previous results using the same methods but in a larger sample with better spatial coverage. A previous work using geometric morphometric and cladistic methods suggested a pattern of general morphological diversification across Patagonia related, at least in part, to the spatial distance between cases, distinguishing two main clades in northern (43-45° S) and southern (50-52° S) Patagonia. In the present work to study this pattern in a more detailed level, a sample of ca. 1200 projectile points was used to obtain statistically different morphological classes performing unsupervised K-means searching. Shape characters were used to describe the different taxonomic units and to perform the phylogenetic analysis (through the Neighbor Joining and Maximun Parsimony methods) using as an ancestor the earliest point type known to the region (Fishtail point). The new results suggest that projectile points with longer and narrow blades and smaller stems evolved later in Patagonia and occupy a different sector of morphospace that could be related to the emergence of different technical systems, like the bow and arrow. However, these results do not support the previous ones of a projectile point diversification pattern mediated by spatial distance, maybe due to the reduction of contrast between the extreme north and south of Patagonia by the larger spatial coverage used in the present analysis.
La ciudad que huye: formação dos 'countries' argentinos e os ruídos da cidade no cinema
Authors: Simião Suelen Caldas de Sousa
Published: November 2019

O presente trabalho se propõe a analisar a presença urbana a partir dos ecos e ruídos da cidade, expressos no curta documentário La ciudad que huye (2006), de Lucrecia Martel, e nos filmes Cara de queso – mi primer ghetto (2006) de Ariel Winograd, Una semana solos (2008) de Celina Murga, Las viudas de los jueves (2009) de Marcelo Piñeyro, Historia del miedo (2014) de Benjamín Naishtat, e Los decentes (2016) de Lukas Valenta Rinner, através do avesso da cidade que se transmuta em cidadela, forjada por uma classe média e alta e sob o contexto de políticas neoliberais. Os filmes aparecem como linguagens singulares que, entrecruzados à luz da documentação técnica, da bibliografia sobre cidades e da compreensão do processo histórico de formação dos countries, nos auxiliam a pensar e problematizar as relações entre sensibilidades, sociabilidades e espaço urbano contemporâneo nessa espécie de “cidade que foge”.

Innovative Diabetes Interventions in the U.S. Hispanic Population
Authors: Fortmann Addie L. , Savin Kimberly L. , Clark Taylor L. , Philis-Tsimikas Athena , Gallo Linda C.
Published: November 2019

IN BRIEF In the United States, Hispanics have a 66% greater risk of developing type 2 diabetes and, once diagnosed, exhibit worse outcomes than non-Hispanic whites. It is therefore imperative to ensure that interventions meet the specific needs of this at-risk group. This article provides a selective review of the evidence on innovative, real-world approaches (both live and technology-based) to improving behavioral, psychosocial, and clinical outcomes in underserved Hispanics with type 2 diabetes. Key aspects of successful live interventions have included multimodal delivery, greater dosage/attendance, and at least some in-person delivery; effective technology-based approaches involved frequent but intermittent communication, bi-directional messaging, tailored feedback, multimodal delivery, and some human interaction. Across modalities, cultural tailoring also improved outcomes. Additional research is needed to address methodological limitations of studies to date and pinpoint the most efficacious components and optimal duration of interventions. Future efforts should also attend to variability within the U.S. Hispanic population to ensure acceptability and sustainability of interventions in this diverse group.
Making Inroads in Addressing Population Health in Underserved Communities With Type 2 Diabetes
Authors: Meneghini Luigi F. , Fortmann Addie L. , Clark Taylor L. , Rodriguez Kellie
Published: November 2019

IN BRIEF Diabetes continues to represent a substantial individual and societal burden for those affected by the disease and its complications in the United States, and especially for racial/ethnic minorities, the socioeconomically disadvantaged, and the underinsured. Although tools and strategies are now available to manage the condition and its associated comorbidities at the patient level, we continue to struggle to gain control of this health burden at the population health level. Most patients are not achieving desired clinical goals and thus continue to be exposed to preventable risks and complications. As the U.S. health system moves toward a more value-based system of reimbursement, there are opportunities to rethink our approaches to patient and population health management and to harness the available tools and technologies to better understand the disease burden, stratify our patient populations by risk, redirect finite resources to high-impact initiatives, and facilitate better diabetes care management for patients and providers alike.

Authors: Raei Dehaghi Morteza
Published: November 2019

The present study aimed to explore and evaluate employee’s capability maturity level and propose a solution to enhance it at Iran’s Oil Company. It was conducted through descriptive-field and cross-sectional method. The statistical population included 269 employees who were selected through simple random sampling and the sample size was estimated using Cochran formula. Curtis standard questionnaire was employed for data collection. Face validity and content validity of the questionnaire were confirmed by several experts including the management professors and managers of the mentioned company. Reliability of the questionnaire was confirmed through Cronbach's alpha coefficient which was equal to 0.89. Having analyzed the research questions, the findings revealed that maturity level of employees is totally weak from the third level onward. Therefore, maturity of employees is at the second level of maturity model, i.e. this company has defined and executed its primary and repeatable processes. Likewise, one-sample t-test for each level showed that status of dimensions in the second level was more than the average level (mean was equal to 3.54 and the significance level was less than 0.05) and it was less than the desirable level in other levels (2.69, 2.61, and 2.59 respectively).

Published: November 2019

The article focuses on studying the operational properties of regenerated engine oils in terms of the impact on the wear of friction units of the trunk diesel engine when it works on the fuel of different grades. There have been built generalized models of marine diesel parts wear on the basis of experimental studies. Diesel 2Ч10,5/13 was used for experiments. Wear was determined by the method of artificial bases and by weighting. Four groups of the main indicators

of fuels used on ships have been considered (depending on the quality indicator). The first group includes distillate fuels and low-viscosity marine fuel which is close in its characteristics to foreign fuels. The second group includes motor fuel, naval fuel oil and export fuels (medium viscosity fuels). The third group presents high-viscosity marine fuel; the fourth group - fuels made from the remains of oil refining. The description of the generalized model of details wear of the tested diesel engine was carried out by a polynomial of the second order. To obtain the model, a non-position plan was chosen for three test variables: concentration of additives in oil, a fuel quality factor and a level of diesel forcing. The superposition of the hypersurfaces of the response of wear functions

of the internal combustion engine with diesel boosting factors at zero, lower, and upper levels with visualizing the effect on engine wear parameters depending on the additives concentration and quality of the fuel used in testing regenerated engine oil has been illustrated. Verification of the model's adequacy has proved that the model is adequate for machines with average effective pressure and a wide range of fuel grades. There has been given the possibility of using the obtained model to estimate the wear value at different values of parametric factors

Authors: Крюков Алексей , Kriukov Aleksei
Published: November 2019

The article describes the low-consumption turbines as reliable, productive, small-sized actuating mechanisms in various units and machines. Experience in production and use

of low-cost turbine stages contributes to improving the efficiency along with simplifying and re-ducing the cost of manufacturing of the blades and the stage in general. Improving the efficiency

of low-consumption turbines requires solving the problem of aerodynamic improvement of the flow part and the calculated determination of the optimal geometry and operating modes of the impeller flow. One of the innovative ways to improve the design efficiency of low-consumption turbines is the automation of the development process using modern modeling systems based on the developed software systems. Due to the small size of the design, the design calculations of turbine stages of this type have been made in a one-dimensional formulation with the involvement of various analogies with classical stages. Using three-dimensional gas dynamic calculations based on the ANSYS CFX platform will significantly improve the quality of design of flow parts of low-flow turbines. Implementation of three-dimensional gas-dynamic calculation of the nozzle unit using the software package ANSYS CFX low-consumption turbine stage can solve this problem. The geometric model is built using AutoCAD software, the grid is selected, the boundary conditions are set. The values of the experimental coefficients of the nozzle velocity, neck velocity and the tangential component of velocity at the nozzle outlet have been compared with the coefficients obtained when using the software package. There have been built the velocity fields and made conclusions about feasibility of using the ANSYS CFX software package to determine the main parameters of a three-dimensional flow of the turbine stage.

A prolonged stay of children in hospitalized condi-tion is a factor in the occurrence of possible emo-tional disturbances, but it should not cause a lasting negative emotional state of the child. In this regard, special attention in the support system is given to the prevention of probable negative emotional reac-tions. In the study, based on observation, the sign and modality of emotions in the structure of the emotional state of older preschool children in the hospital are determined. It has been established that negative emotional states are characteristic of chil-dren, which can be changed with timely organized psychological and pedagogical support. The study was aimed at reducing emotional stress in the com-munication of children with each other, so all clas-ses were held in subgroups. After that, the tasks were set to correct fears and anxieties associated not only with the hospital, but also with the mani-festation of the individual characteristics of children.

Authors:   Moscow State University, Yurtikova Nadezhda Vladimirovna
Published: November 2019

The social inequality as a phenomenon of social life, characterized by the manifestation of various forms of differentiation in the form of income, the availabil-ity of property, access to medical, educational, cul-tural goods, and the quality of meeting needs is considered in the article. Moreover, social differenti-ation is an integral part of any society. Given that modern society is characterized by a high degree of social polarization, a difference in property status, income level, and quality of satisfying needs, the state social policy should be aimed at increasing the well-being of individuals, satisfying their material, social and intellectual needs. At present, in the Rus-sian Federation, in order to ensure the growth of well-being of the population, the development of human potential, a General Agreement has been adopted between the all-Russian associations of trade unions, the all-Russian associations of em-ployers and the Government of the Russian Federa-tion for 2018–2020. Some aspects of this agreement are discussed in the article.

The paper presents the results of pilot research of environment factors and individual-psychological features of students educational space representa-tion. On the basic of construct “place”, which is developed in environmental psychology, the authors consider such indicators of representation as the frequency of representation and the ranking of the place in the educational space as relevant criteria for the importance of this place for the student. The high-ranking (preferred) and low-ranking (rejected) places in educational environment are highlighted, a connection has been established between prefer-ences and rejections of places with environmental and individual psychological characteristics of stu-dents. It was found that the organization of the spa-tial-subject environment of a university can be a factor determining the characteristics of the repre-sentation of the educational environment by a stu-dent. An attempt was made to detect a connection between sex and the features of students’ educa-tional space representation, as well as between such individual psychological characteristics as extraver-sion, friendliness, consciousness, neuroticism and openness, and the qualities of representation. It was established that environmental factors, to a greater extent than individual psychological traits, are re-sponsible for differences in the representation of the educational environment of the university by stu-dents.
