Abstract
Pultrusion is considered to be a cost efficient method for developing composite structures. It facilitates the fabrication of uniform cross-section products with improved fiber alignment, mechanical properties, good surface characteristics, etc. In order to ascertain the crashworthiness, the pultruded composites shall be able to resist impact loads, and in this concern, the energy absorption capacity of the pultruded composites must be explored. This article presents the experimental and numerical investigation of the crushing behavior of polyester based pultruded composite with rectangular cross section. Pultruded rectangular tubes with e-glass/polyester composites have been developed for this study. The cross-section of the tubes was developed into two triggering profiles, the uniform edge around the section and the tulip pattern. The tubes were subjected to impact loads, and the effect of these triggering profiles on the energy absorption capacity of the tubes has been investigated. The testing of all composites has been carried out at three different impact velocities (10, 20 and 45 mm/min). The results have revealed the dependence of crushing behavior of the tubes on the loading velocity and the triggered profiles. Lower peak load and high specific energy absorption (SEA) was observed in the tube with tulip pattern profile. The results obtained from the simulation have also shown consistency with the real-time experiments.

Abstract
Removal of 137Cs radionuclides from the environment has engrossed the concern of researchers after Fukushima accident. The leakage of radioactive cesium ions can lead up to surface and groundwater contamination, and this leads to pollution of drinking water sources. In this work, corchorus olitorius stalks has been used as a novel precursor for production of low-cost

). The physicochemical properties of all adsorbents were evaluated. The influences of sorption parameters and presence of some ligands (humic acid, fulvic acid, and EDTA) on the sorption of 137Cs were studied. The maximum 137Cs capacity of
m-Meso-AC
was found to be 58.74 mg/g. Efficiency of the new adsorbent to remove 137Cs radionuclides from natural waters (tap, river, and groundwater) was investigated. The studies showed that new adsorbent could be used as promising material for the retention of 137Cs from real radioactive waste and natural water samples.

AbstractObjectivesThis research aims to analyse the relationship between urine mercury levels and neurological problems.MethodsThis research is an observational study with a cross-sectional approach. There are 44 goldsmiths in the gold jewellery small scale industry involved in this study. Urine mercury levels were measured using an atomic absorption spectrophotometer. Neurological problems were assessed by a medician. Data collected includes age, time of exposure, work duration, smoking behaviour and nutrition status of the goldsmiths which were obtained by interview.ResultsThe results showed that the concentration of mercury in the goldsmith’s urine was around 0.93–64.59 μg/L. The analysis showed that there were 63% of goldsmiths experiencing neurological problems, such as tremors (9.1%) and knee pass reflex (6.8%). The bivariate analysis showed that there is no significant relationship between the concentration of mercury (p=0.133), age (p=0.155), time of exposure (p=0.702), time of working (p=0.354), smoking behaviour (p=0.169) and nutrition status (p=0.541) with neurological problems.ConclusionsThe goldsmiths who had high levels of mercury in urine samples were diagnosed with at least one of the neurological symptoms. It is recommended that the goldsmith use personal protective equipment during work such as mask, glasses and gloves.

Abstract
Rapid escalation in energy demand and pressure over finite fossil fuels reserves with augmenting urbanization and industrialization points towards adoption of cleaner, sustainable and eco-friendly sources to be employed. Solar cell devices known for efficient conversion of solar energy to electrical energy have been attracting scientific community due to their remarkable conformity with the principles of green chemistry. The future candidacy of solar cells is expressed by their efficient conversion. Such a great potential associated with solar cells has instigated research since many decades leading to the emergence of a wide myriad of solar cells devices with novel constituent materials, designs and architecture reflected in form of three generations of the solar cells. Considering the cleaner and sustainability aspects of the solar energy, current review has systematically compiled different generations of solar cells signifying the advancements in terms of architecture and compositional parameters. In addition to the chronological progression of solar cells, current review has also focused on the innovations done in improvement of solar cells. In terms of efficiency and stability, photovoltaic community is eager to achieve augmented efficiencies and stabilities for using solar cells as an alternative to the conventional fossil fuels.

Abstract

Objectives
Depression symptomatology is highly prevalent in patients with chronic pain, but accurate identification of major depression may be challenged due to time constraints and diagnostic interviews are therefore not routinely performed in clinical practice. Assessment of depression may be facilitated through the use of full-length depression screening questionnaires with acceptable construct validity and test-retest reliability. However, as previously indicated screening questionnaires may overestimate depression in patients with chronic pain, possibly due to overlapping symptoms. However, the failure to screen for depression may raise a concern for missing relevant cases with depression. The objectives of this study were to (1) quantify the validity of the 9-items Patient-Health Questionnaire (PHQ9) and the Major Depression Inventory (MDI) compared with a diagnostic interview in patients with chronic pain seeking specialist pain treatment, and (2) assess the relative test-retest reliability of PHQ9 and MDI over two weeks.

Methods
Responses to the PHQ9 and MDI were compared with a Present-State-Examination (PSE) interview in 99 patients with chronic pain referred to interdisciplinary pain treatment. PHQ9 and MDI were completed twice over two weeks. Construct validity were assessed with the area under the curve (AUC) analysis, and performance characteristics derived from 2 × 2 contingency tables in which scores on the screening questionnaires were dichotomized and compared with the classification of clinical depression based on the diagnostic interview. Relative test-retest reliability was assessed with intraclass correlation coefficients (ICC).

Results
Based on the PSE interview, the prevalence of depression was 22.2%, and according to the PHQ9 and MDI questionnaires the prevalence was 26.3 and 34.3%, respectively. Compared with the diagnostic PSE, the PHQ9 and MDI questionnaires had areas under the curve of 0.83 and 0.88, respectively. Both questionnaires had high negative predictive values (PHQ9: cut-off of 11; MDI: cut-off of 26), but low positive predictive values for all possible scores. ICC values were excellent.

Conclusions
The PHQ9 and MDI questionnaires reliably identified chronic pain patients unlikely to have clinical depression, but showed limited validity identifying patients with clinical depression. These preliminary results may have clinical implications in depression screening in patients with chronic pain seeking specialist pain treatment. Clinicians in a specialty care pain clinic can use these screening questionnaires to identify patients without depression, but caution should be used when positive cases are identified by PHQ9 or MDI due to the risk of false positives.

Zusammenfassung
Der vorliegende Beitrag vertritt und entfaltet die These, dass seelsorgliche Praxis in der aktuellen Krise eine wichtige Orientierungsmarke darstellt, durch die aufgrund digitaler Transformationsprozesse neues Nachdenken über die seelsorgliche Präsenz von Kirche in vielfältiger Gestalt auch über die Krise hinaus notwendig ist. Von einer grundsätzlichen poimenischen (seelsorgetheorischen) Perspektive aus werden aktuelle Herausforderungen benannt sowie am Beispiel erweiterter Telefonseelsorgeangebote Einblicke in aktuelle Formen digitaler seelsorglicher Praxis in Coronazeiten gegeben. Von dort aus werden in theologischer Perspektivierung Kernaspekte seelsorglicher Praxis unter Krisenbedingungen benannt sowie Folgerungen für die Zukunft seelsorglicher Praxis im Kontext einer Kultur der Digitalität angestellt.
Marginalisierung in der Marginalität?
Authors: Mattfeldt Anna 
Published: July 2020

AbstractThis article discusses marginalisation in internet forums and blogging platforms using the example of asexuality blogs and discussion threads. While large corpora of both English and German, such as COCA and DeReKo, contain hardly any mention of asexuality and these few instances of asexuality and related expressions typically refer to plant biology, online communities do discuss aspects of life as an asexual person and their experiences of marginalization even within the LGBTQ community. Definitions of asexuality, including its delineation from other identities, and how asexual people articulate conflicts and other issues on these online platforms are discussed in detail. Particular attention is paid to how this particular group is constructed by others, how they construct themselves as not being part of the mainstream, and the role (self-)marginalisation plays in this context.
Vom Militär-Invalidenhaus zur modernen Behindertenpolitik
Authors: Obinger Herbert , Grawe Lukas 
Published: July 2020

AbstractUnmittelbar nach Ende des Ersten Weltkriegs wurden die vorrangig auf Berufsarmeen zugeschnittenen Militärversorgungssysteme in Deutschland und Österreich auf eine neue Basis gestellt. Dieser Beitrag untersucht aus vergleichender Perspektive die kurz- und langfristigen Auswirkungen der vor hundert Jahren geschaffenen Kriegsopferversorgung auf die Entwicklungsdynamik und Struktur staatlicher Sozialpolitik. Die republikanischen Versorgungs- und Eingliederungsgesetze beider Länder können als ein frühes Beispiel für eine gleichermaßen aktive wie aktivierende Arbeitsmarktpolitik gesehen werden, die v. a. nach dem Zweiten Weltkrieg von den überwiegend männlichen Kriegsbehinderten auf alle behinderten Menschen ausgeweitet wurde und zudem zum Vorbild weiterer Entschädigungssysteme und – in Österreich – des Bundespflegegelds wurde. In fiskalischer Hinsicht führten die hohen Kosten der Kriegsopferversorgung zu einem erheblichen Anstieg der Sozialausgaben, wodurch jedoch der Ausbau ziviler Sozialpolitik kurzfristig gebremst wurde.

Published: July 2020

Background:
Whether polymorphisms in VDR gene affect the risk of postmenopausal osteoporosis or not remain unclear. Thus, the authors performed a meta-analysis to more robustly assess associations between polymorphisms in VDR gene and the risk of postmenopausal osteoporosis by integrating the results of previous literature.

Methods:
Medline, Embase, Wanfang, VIP and CNKI were searched comprehensively for eligible literature, and 67 genetic association studies were finally selected to be included in this meta-analysis.

Results:
We found that ApaI rs7975232 (dominant comparison: OR = 0.77, P = 0.007; allele comparison: OR = 0.81, P = 0.04), BsmI rs1544410 (dominant comparison: OR = 0.69, P = 0.002; allele comparison: OR = 0.78, P = 0.008) and TaqI rs731236 (recessive comparison: OR = 1.32 , P = 0.01) polymorphisms were significantly associated with the risk of postmenopausal osteoporosis in Caucasians, whereas FokI rs10735810 polymorphism was significantly associated with the risk of postmenopausal osteoporosis in Asians (dominant comparison: OR = 0.61, P = 0.0001; recessive comparison: OR = 2.02, P = 0.001; allele comparison: OR = 0.68, P = 0.002).

Conclusions:
This meta-analysis shows that ApaI rs7975232, BsmI rs1544410 and TaqI rs731236 polymorphisms may affect the risk of postmenopausal osteoporosis in Caucasians, while BsmI rs1544410 polymorphism may affect the risk of postmenopausal osteoporosis in Asians.

AbstractIntroductionIn Mexico, there are considerable health system delays in the diagnosis and treatment initiation of women with breast cancer. Alerta Rosa is a navigation program in Nuevo Leon that aims to reduce barriers that impede the timely management of these patients.Patients and MethodsSince December 2017, women who registered to receive medical evaluations by Alerta Rosa were stratified based on their clinical characteristics into three priority groups (“Red,” “Yellow,” and “Green”). According to the category assigned, patients were scheduled imaging studies and medical appointments with breast specialists on a preferential basis.ResultsUp until December 2019, 561 patients were scheduled for medical evaluations. Of them, 59% were classified as “Red,” 25% “Yellow,” and 16% “Green” priority. The median time from stratification to first medical evaluation was 4, 6, and 7 days, respectively (p = .003). Excluding those who had a prior breast cancer diagnosis, 21 patients were diagnosed by Alerta Rosa, with the initial “Red” priority classification demonstrating a sensitivity of 95% (95% confidence interval [CI], 75.1%–99.9%) and specificity of 42% (95% CI, 37.1%–47.1%) for breast cancer. The median time elapsed from initial patient contact to diagnosis and treatment initiation was 16 days and 39 days, respectively. The majority (72%) of patients were diagnosed at an early stage (0–II).ConclusionThis patient prioritization system adequately identified women with different probabilities of having breast cancer. Efforts to replicate similar triage systems in resource-constrained settings where screening programs are ineffective could prove to be beneficial in reducing diagnostic intervals and achieving early-stage diagnoses.Implications for PracticeLow- and middle-income countries such as Mexico currently lack the infrastructure to achieve effective breast cancer screening and guarantee prompt access to health care when required. To reduce the disease burden in such settings, strategies targeting early detection are urgently needed. Patient navigation programs aid in the reduction of health system intervals and optimize the use of available resources. This article presents the introduction of a triage system based on initial patient concern. Appointment prioritization proved to be successful at reducing health system intervals and achieving early-stage diagnoses by overcoming barriers that impede early access to quality medical care.
Evaluating the use of iron-coated tubes for wetland delineation in South Africa: A pilot study in the Kruger National Park
Authors: CW van Huyssteen  , TL Johnson  
Published: July 2020

The identification of hydric soils is important for wetland delineation and protection. South Africa currently uses the Department of Water Affairs and Forestry (DWAF) wetland delineation guidelines which can be subjective in certain contexts. A robust technical standard that can be legally conclusive is therefore required and should be developed for South African conditions. The National Technical Committee of Hydric Soils (NTCHS, 2007) in the United States of America has accepted the Indicator of Reduction in Soils (IRIS) tube methodology as a technical standard, but this had not yet been tested in South Africa. It is proposed that the NTCHS (2007) be adapted for use in South Africa. These Fe-coated tubes are installed into the soil and if reducing conditions are present, the Fe coating is removed. The aim of this study was to evaluate the use of IRIS tubes as a technical standard for wetland delineation in South Africa. The study took place in three different wetland systems (Malahlapanga, Nshawu and the Tshuthsi spruit) in the Kruger National Park. Piezometers were installed in triplicate in each zone, and the water table, pH and Eh were recorded monthly. Soils were classified, soil wetness indicators identified, and vegetation described. The study took place from September 2012 to August 2013. The areal percentage of paint removed from the top 300 mm of the IRIS tubes was quantified by scanning the tubes and then compared to the DWAF wetland indicators. It was found that the DWAF indicators and the IRIS tube method were mostly in agreement; however, the conditions at the Tshutshi spruit were not favourable for Fe reduction, and hence the use of IRIS tubes, due to the high pH values recorded. The IRIS tubes were therefore a useful tool for wetland delineation in the majority of conditions, but are not recommended in high pH, sodic environments. Further research is recommended over a wider geographical area as well as testing the MIRIS methodology (Manganese Indicators of Reduction in Soils) in wetlands that would inhibit Fe reduction.
