Association between Self-Rated Health and Quality of Life with Sleep Quality Among Bangladeshi University Students
Authors: Ahmed Md. Sabbir , Sen Liton Chandra , Griffiths Mark D. 
Published: June 2020

Introduction:
Poor sleep quality is adversely affecting student's mental health. However, the impact of poor sleep quality on student's health and quality of life (QOL) has not been previously studied in Bangladesh. The objective of this study was to assess the association between self-rated health (SRH) and QOL of university students with their sleep quality.

Methods:
A quantitative cross-sectional survey was carried out among 332 students of Patuakhali Science and Technology University (Bangladesh) aged from 18 to 25 years (mean = 21.6 years; standard deviation ± 1.7). Data were collected through one-to-one interviews using a pretested structured questionnaire. Results: There was a significant association between SRH and QOL with sleep quality. Students experiencing poor sleep quality had a 2.4 times higher risk for poor SRH (odds ratio [OR] = 2.45, 95% confidence interval [CI]: 1.21–4.95,P= 0.012) The OR of poor QOL was 3.3 times higher among the students whose sleep quality was poor (OR = 3.38, 95% CI: 1.70–6.75,P= 0.001).

Conclusion:
Study findings indicated that poor sleep quality adversely affects the health status and QOL of Bangladeshi university students. University authorities in Bangladesh should develop programs to improve the overall health and sleep quality of the students.
To Wear or Not to Wear? Factors Influencing Wearing Face Masks in Germany During the COVID-19 Pandemic
Authors: Rieger Marc Oliver 
Published: June 2020

Introduction:
During the COVID-19 pandemic, it has been advised to wear masks. Attitudes toward wearing masks have not been investigated well. We want to provide data on whether and why people would be willing to wear masks in order to suggest ways for enhancing compliance.

Methods:
We conducted a survey among 206 participants on April 20 to 22, 2020. The sample mean age was 28 years, 63% of the participants were female, 64% were undergraduate or graduate students, and 51% had a university degree. Data from a previous study (n = 241, mean age of 26 years, 66% females, 83% students, 52% with a university degree) have also been used.

Results:
Fifty to eighty percent of the participants stated they would (probably) wear a mask (if they had one) in most scenarios. On the street, only 21% said they would. Demographic factors did not prove to be significant, whereas a university degree increased the likelihood of wearing a mask. Determining factors included worries about the current situation, self-protection, protecting others, thinking that wearing a mask looks strange, and being afraid of others' judgment when wearing a mask. The significance of these factors varies strongly between the age groups. Nearly all participants stated they would wear a mask if it were legally required, but compliance would be lower if the law required them to wear masks on the street. Surprisingly, there is no difference in attitudes toward masks as compared to the results of the previous survey from March 24 to 25, 2020.

Conclusion:
Legally requiring people to wear face masks seems to be an essentially effective instrument in this case. Studying the voluntary use of masks, we find that in different groups, wearing (or not wearing) a mask can be attributed to various reasons. Potential campaigns should therefore be tailor-made for different demographic groups.
Khovanov–Rozansky homology for infinite multicolored braids
Authors: Willis Michael 
Published: June 2020

AbstractWe define a limiting

${\mathfrak {sl}_N}$
Khovanov–Rozansky homology for semi-infinite positive multicolored braids. For a large class of such braids, we show that this limiting homology categorifies a highest-weight projector in the tensor product of fundamental representations determined by the coloring of the braid. This effectively completes the extension of Cautis’ similar result for infinite twist braids, begun in our earlier papers with Islambouli and Abel. We also present several similar results for other families of semi-infinite and bi-infinite multicolored braids.
Survey of health care student attitudes towards transgender health care education
Authors: Shukla Vipul , Asp Alex , Saltzman Barbara , Duggan Joan 
Published: June 2020

Background: This study assessed health care trainees perceptions of their education regarding transgender health care issues and personal and professional comfort level with the provision of transgender health care. An online 20 question survey (2013) about trainee experience and education on transgender health care was administered to medical (MD), nurse practitioner (NP), and physician assistant (PA) students at a single institution. Methods: The survey instrument consisted of seven demographic questions and 13 non-demographic questions about education in transgender health, hours of education received, and personal and professional comfort with transgender medical care. Non-demographic questions were written as even-point Likert scale questions with four rating options (very comfortable, somewhat comfortable, somewhat uncomfortable, and very uncomfortable). Results: A total of 484 MD, NP, and PA students responded to the online survey out of 1,035 eligible students (47% response rate). Only 74 (15%) respondents had provided medical care to a transgender patient. Provision of medical care to a transgender patient was associated with increased hours of education on transgender health issues (P<0.001). The majority of MD, NP and PA students (n= 374/ 77%) were personally comfortable or very comfortable with providing medical care to transgender patients. Conclusions: MD, NP, and PA students are personally comfortable with transgender patients but the vast majority do not come into contact with this patient population during their preclinical or clinical years. Increased student contact with transgender patients is associated with increased educational hours on transgender health care issues and is needed to provide the fullest educational experience for trainees in this area.
Medical Clearance Prior to Psychiatric Evaluation in a Tertiary Pediatric Emergency Department: Value and Cost Analysis
Authors: Redfern Roberta , Brown Megan , Izsak Eugene 
Published: June 2020

Background: Medical clearance in the emergency department for patients undergoing psychiatric evaluation is often required prior to admission to rule out organic cause and because many psychiatric facilities are unable to treat medical conditions. This may be low yield in pediatric populations as the likelihood of disease requiring intervention is low in this setting.
Objectives: To determine whether routine laboratory testing in an urban, tertiary pediatric hospital emergency center impacted the overall management of patients presenting with chief complaints requiring psychiatric evaluation.
Methods: Retrospective analysis of all psychiatric admissions over a one year period at a large urban tertiary pediatric hospital. Laboratory test results were compared with history and physical notes to determine whether abnormal results could have been anticipated based on patient report. Additional medical interventions required and overall impact on management was recorded. Cost analysis was based on public reimbursement rates, considering tests without impact on intervention to be unnecessary.
Results Overall, 1824 tests laboratory tests were performed in 289 patients admitted for psychiatric treatment. There were 161 abnormal results (8.8%), most of which could be anticipated by the medical history. No abnormal result laboratory result led to a change in management for any patient. The sensitivity and negative predictive value for patient-reported drug use compared to urine drug screen results were high, both over 90%.
Conclusions Medical clearance in this population is low yield; most abnormal results can be anticipated by patient report or do not require any clinical intervention. The cost of these unnecessary tests was over $500,000.
Evaluation of Pan-Sharpening Techniques Using Lagrange Optimization
Authors: Bidyarani Devi Mutum , Rajagopalan Devanathan  
Published: June 2020

Earth’s observation satellites, such as IKONOS, provide simultaneously multispectral and panchromatic images. A multispectral image comes with a lower spatial and higher spectral resolution in contrast to a panchromatic image which usually has a high spatial and a low spectral resolution. Pan-sharpening represents a fusion of these two complementary images to provide an output image that has both spatial and spectral high resolutions. The objective of this paper is to propose a new method of pan-sharpening based on pixel-level image manipulation and to compare it with several state-of-art pansharpening methods using different evaluation criteria. The paper presents an image fusion method based on pixel-level optimization using the Lagrange multiplier. Two cases are discussed: (a) the maximization of spectral consistency and (b) the minimization of the variance difference between the original data and the computed data. The paper compares the results of the proposed method with several state-of-the-art pan-sharpening methods. The performance of the pan-sharpening methods is evaluated qualitatively and quantitatively using evaluation criteria, such as the Chi-square test, RMSE, SNR, SD, ERGAS, and RASE. Overall, the proposed method is shown to outperform all the existing methods.
Karl Marx sobre la dictadura del proletariado y la revolución en permanencia. Dos documentos de 1850
Authors: Quiroga Manuel , Gaido Daniel 
Published: June 2020

Los primeros usos documentados por parte de Marx de la expresión “dictadura del proletariado” (una consigna no incluida en el Manifiesto comunista) corresponden al año 1850 y son los siguientes:
• Karl Marx, “Las luchas de clases en Francia, 1848-1850” (enero-marzo 1850).
• Règlement de la Société Universelle des Communistes Révolutionnaires (abril 1850).
• Declaración a la Neue Deutsche Zeitung nº 158 (25 de junio de 1850).
En esta edición incluimos versiones españolas de los últimos dos documentos, traducidos de los originales en francés y alemán. Es interesante constatar que, en los tres casos antes mencionados, Marx utiliza la expresión “dictadura del proletariado” junto con la de “revolución en permanencia” –una estrategia sistematizada en el “Mensaje del Comité Central a la Liga de los Comunistas”, escrito por Marx y Engels a fines de marzo de 1850 (Marx y Engels, 1850) con la intención de expresar las conclusiones políticas que ambos creían necesario extraer de la experiencia de las revoluciones de 1848–.
Acceso a la justicia en materia ambiental en la unión europea
Authors: Bravo Álvaro Sánchez 
Published: June 2020

La justicia ambiental constituye, en la Unión europea, el tercer pilar de garantía para los ciudadanos en la defensa de nuestro medio ambiente. Junto al acceso a la información, y la participación en materia ambiental, la justicia ambiental presenta un carácter dual: por un lado, el enjuiciamiento por los tribunales de justicia de todas aquellas materias, públicas y privadas, que puedan tener un impacto en las políticas ambientales; y por otro, la garantía de la legitimación ciudadana para impetrar acciones legales en defensa del medio ambiente, y ser, por tanto, parte legitimada en los procesos de esta naturaleza. en la Unión europea, la justicia ambiental, había quedado olvidada por hechos de diferente etología, hasta la aprobación en 2017 de la Comunicación de la Comisión relativa al acceso a la justicia en materia medioambiental, que vino a colmar esa laguna y dar carta de naturaleza a este derecho ciudadano tan relevante.
Ayurvedic Management of Fistula in Ano
Authors: Shankar KM Pratap , SreeDeepthi GN , KS Rohit , Swamy GK 
Published: June 2020

Introduction:
Fistula in ano is considered to be complicated and vicious due to its nature of recurrences and exacerbations. Ayurveda includes this disease under the list of Asta Mahagada (eight serious diseases that are difficult to treat by nature itself) due to this attribute. Ayurvedic literature offers various effective and safe management strategies for fistula in ano. Several works have been conducted to prove the efficacy and effectiveness of various treatment modalities mentioned in Ayurvedic texts. Kshara sutra, Kshara karma, Agnikarma, and Ksharavarti are a few to name in this list. A lacuna exists in not analyzing or compiling these works. Hence, the purpose of this systematic review is to generate evidence for efficacy, effectiveness, and safety profile of Ayurvedic interventions in the management of fistula in ano.

Materials and methods:
Electronic search from various online databases and clinical trial registers will be done. Manual search for gray literatures will be done from various colleges and universities. There will be no language restrictions. Three authors independently will screen all citations and abstracts to identify potentially eligible trials. Based on the inclusion criteria, full articles will be evaluated and disagreements will be discussed among the three authors. Data extraction from the included studies will be done by the three reviewers independently with extraction forms containing methods, participants, interventions, comparators/controls, and outcomes. Each of the included trials will be assessed for risk of bias. Primary data analysis will be done for both qualitative and quantitative data. Heterogeneity among trials will be assessed by inspecting forest plots. If heterogeneity is detected, and it is still considered clinically meaningful to combine studies, a random- effects model will be used. Meta-analysis will be done for pooled estimates and others would be presented as narrative synthesis and shall be represented in tabular and graphical forms.

Dissemination:
The systematic review will be published in a peer-reviewed journal. It will also be disseminated electronically and in print. The review may guide healthcare practices and policy framing regarding the treatment of fistula in ano with Ayurvedic interventions.

Tancaite-(Ce), ideally FeCe(MoO&lt;sub&gt;4&lt;/sub&gt;)&lt;sub&gt;3&lt;/sub&gt; ● 3H&lt;sub&gt;2&lt;/sub&gt;O: description and average crystal structure
Authors: Bonaccorsi Elena , Orlandi Paolo 
Published: June 2020

Abstract. Tancaite-(Ce), ideally FeCe(MoO4)3⚫3H2O, is a new mineral occurring within cavities in the quartz veins
which cut the granite at Su Seinargiu, Sarroch (CA), Sardinia, Italy. It is
a secondary mineral formed in the oxidation zone of a sulfide ore vein.
Associated minerals are quartz, muscovite, molybdenite, pyrite, and a
mendozavilite-like phase. Tancaite-(Ce) is red or pale brown in colour, with
a vitreous to adamantine lustre. Electron microprobe analyses give
(wt %) SiO2 0.34, CaO 0.09, Fe2O3 11.29, SrO 0.02,
La2O3 5.04, Ce2O3 10.35, Pr2O3 1.07,
Nd2O3 3.66, Sm2O3 0.19, ThO2 2.58, UO2 0.17,
MoO3 58.62, and H2O (calculated) 7.43, with a sum of 100.85, from which the
empirical formula is calculated. The empirical formula
Fe1.033+(Ce0.46La0.23Nd0.16Pr0.05Sm0.01U0.01Th0.07)Σ=0.99(Mo2.96Si0.04)Σ=3.00O12⚫3H2O can be simplified as Fe3+(REE)(MoO4)3⚫3H2O and idealized as FeCe(MoO4)3⚫3H2O. The
presence of H2O was confirmed by micro-Raman spectrometry (stretching
and bending vibrations of O–H). The calculated density is 3.834 g cm−3.
The X-ray diffraction pattern of tancaite-(Ce) is characterized by a set of
strong reflections, which point to a cubic subcell with a=6.870(1) Å
and space group Pm3¯m, plus a set of superstructure reflections. Tancaite-(Ce)
displays a new structure type not previously reported in natural and
synthetic molybdates. By considering only the strong reflections, it was
possible to solve and refine its average structure (R1=0.038 for 192 unique reflections with I>2σ(I)). The crystal structure
consists of FeO6 octahedra centred at the origin of the cubic
subcell and linked together through MoO4 tetrahedra by corner sharing.
The Mo-centred tetrahedra are statistically distributed in four
symmetry-related positions, with one-fourth occupancy. In the centre of
the cubic unit cell the REE cations exhibit a 6+3 coordination, bonding
six oxygen atoms and three H2O molecules, each of them being disorderly
distributed in four symmetry-related positions. One of the possible
supercells, with a 48-fold volume with respect to the primitive cubic small
subcell, corresponded to a rhombohedral lattice, with a≈19.43 and c≈47.60 Å in the hexagonal setting. Several unsuccessful trials
were performed to solve the real crystal structure of tancaite, by indexing
the additional superstructure reflections and using their intensities to
refine an ordered structural model. The new mineral has been approved by the
IMA CNMNC (no. 2009-097). The name comes from Giuseppe Tanca, an Italian amateur
mineralogist, who discovered the mineral and gave it to us for studying.

Published: June 2020

Introduction: In Kazakhstan, a post-Soviet country in Central Asia, salt intake is estimated as high, potentially contributing to the morbidity and mortality from cardiovascular diseases. The aim of this study was to explore salt intake in residents of the capital of Kazakhstan, Nur-Sultan.Methods: An online cross-sectional survey of knowledge, attitudes, and behaviors on salt intake among young adult residents of the capital city of Kazakhstan was conducted (n = 237). Bivariate and multivariate linear regression analyses were performed.Results: Although 95% (n=225) reported knowledge on the adverse health effects of high salt intake, older respondents were more aware of its association with high blood pressure (p = 0.007), heart disease (p = 0.037), and heart attack (p = 0.002). Only one-third (n=79) correctly identified the recommended level of daily salt intake. Females reported more awareness of Kazakhstani people consuming salt more than recommended (p = 0.0027) and that processed products constituted the major source of salt in diet (p = 0.007). General dietary concern (p < 0.001), high self-assessment of salt intake (p < 0.001), and older age (p = 0.012) were found to be adjusted predictors of salt-reducing behavior.Conclusion: Lack of reported knowledge on salt-health relationship is of concern, especially among young males. A greater dietary concern and individual awareness of the excessive salt consumption is likely to assist in reducing salt intake. Further studies are required to validate the findings of this pilot study on a bigger population level in order to provide a basis for future salt related interventions and policy changes in Kazakhstan.
Economic Analysis of Utilization of Corn Stover for Bioenergy Production: Towards Diversifying Income Opportunities for Small Farmers
Authors: Alegbeleye Ibukun D. , Illukpitiya Prabodh 
Published: June 2020

Bioenergy production from plant wastes such as corn stover has the potential to improve energy security and mitigate climate change in the United States. However, there is a limited understanding of its utilization and economic potentials for bioenergy production. The overall objective of the study was to estimate the economic profitability of utilizing corn stover for different ventures after harvesting corn, which includes: 1) corn stover production, 2) ethanol production, and 3) electricity generation through on-farm gasifiers. The data for this study was based on secondary data from various sources. The benefit-cost model was applied for the analysis. Investment evaluation criteria include annualized net return from corn stover, ethanol, and electricity generation. Results show that under current conversion rate, the net return from marketing corn stover ranges from $80.61/kg to $394.11/kg, while the net return from ethanol production ranges from $-104.91/ha to $848.96/ha of corn stover under varying price and yield scenarios. Also, under the government subsidy scheme that covers 25% of equipment costs, there is an investment opportunity for on-farm gasifier with an NPV of $4,329.29. The findings of the study show the potential for using corn stover for bioenergy production since it showed a positive net return. Also, the production of ethanol from corn stover is not only economically feasible but also socially acceptable since it does not compete with food production, and serves as a means of income diversification for corn farmers.
Keywords: Corn stover, plant waste, biofuel, ethanol, benefit-cost, gasifier.
Variabilité pluviométrique dans le bassin versant du Haut et Moyen Cheliff

Published: June 2020

L'Algérie, un pays aride à semi-aride, est très vulnérable aux changements climatiques. La pluviosité limitée sur sa zone côtière, incertaine, voire inexistante vers le sud, est particulièrement sensible aux effets négatifs du réchauffement climatique. La tendance est à la baisse depuis l’année 1975 et la phase ascendante des pluies n’est pas encore prête d’être amorcée. C'est dans cette perspective que se situe le présent travail qui a pour objectif d’analyser la variabilité interannuelle des séries chronologiques de 17 stations pluviométriques du bassin versant du Haut et Moyen Cheliff sur la période 1972/73-2012/13 (soit 42 ans). Ces séries chronologiques sont soumises à la méthode de la moyenne mobile à sept ans et à des tests statistiques non paramétriques de rupture (Pettitt et Mann-Kendall). Cette analyse fait apparaitre une alternance de périodes humides 1972/73 à 1979/80 et d'autres sèches 1979/80 à 2005/06 communes à 14 stations. La date de rupture décelée pour la majorité des séries analysées se situe entre la fin des années 1970 et le milieu des années 1980. En effet, 6 stations sur 17 présentent une régularité du régime pluviométrique. Les 11 stations restantes enregistrent un déficit pluviométrique qui oscille entre 16 et 29 %.
Évaluation de la pollution azotée minérale des eaux superficielles de la zone humide Ramsar du lac Fetzara (Nord-Est algérien)
Authors: Boulaksaa Khaoula , Laifa Aziz 
Published: June 2020

Par sa taille et sa spécificité, la zone humide Ramsar du lac Fetzara est représentative du type rare de zone humide naturelle de la région méditerranéenne. L’activité agropastorale pratiquée dans sa zone périphérique et les eaux résiduaires des agglomérations urbaines avoisinantes constituent des sources potentielles de pollution de ses eaux par les éléments nutritifs. Cette étude a été menée avec l’objectif d’évaluer la pollution des eaux superficielles de la zone humide du lac Fetzara par l’azote minéral. Par une approche physicochimique spatiotemporelle, les résultats analytiques obtenus montrent que les eaux de cette zone humide ne sont pas polluées par l’ion nitrate, alors que la majorité de ces eaux sont riches en ions nitrites. L’activité agricole qui caractérise cette zone serait la source directe ou indirecte de pollution. En ce qui concerne la contamination en ions ammonium, toutes les stations étudiées présentent une pollution nette avec des valeurs maximales (jusqu’à 20,7 mg∙L-1) dans les stations qui reçoivent des eaux résiduaires urbaines. Les concentrations en azote minéral deviennent considérablement élevées au cours de l’année 2016 et varient spatialement selon la distance d’éloignement de la source de pollution et par rapport à la saison, humide et sèche.
