Authors: Rahmawati Anis , Suryani Nunuk , Akhyar Muhammad , Sukarmin  
Published: July 2020

Abstract
An alignment between technology and teachers is required to attain a successful integration of technology in the learning process. This alignment should be started at the teacher training program. This article outlines how the literature points toward Project-Based Learning (PBL) with technology integration in pre-service teacher education. The literature review focuses on describing how technology integrated with project-based learning along with the investigation of what influencing the successfulness on PBL’s implementation by integration of technology. The five steps on Systematic literature reviews (SLR) are chosen as a systematic approach for reviewing the literature. Based on the defined inclusion and exclusion criteria, 16 technology integration in PBL studies published between January 2015 and July 2019 was remained and selected to be investigated further. Analysis of the selected studies revealed that the most popular technology integrated with PBL was social media, following by a learning management system. The teacher’s ability to give guidance during the learning process is the most influential factor for the success of technology integration in PBL.

Published: July 2020

Abstract
A facile method to prepare low-density polyethylene (LDPE)/polystyrene (PS) interpolymer resin particles by swelling suspension polymerization without addition of extra swelling agent was developed. The polymerization temperature, polymerization time, and initiator concentration were investigated. Fourier transform infrared spectroscopy analysis confirmed that the LDPE/PS interpolymer resin particles were successfully prepared and a small amount of PS-g-LDPE existed in the resin. Scanning electron microscopy revealed that PS was uniformly distributed in the LDPE matrix, indicating excellent compatibility between PS and LDPE. The mechanical properties of LDPE/PS interpolymer resin were intermediate between PS and LDPE polymers.

Zusammenfassung
Die Energiewende erzielt weiterhin hohe allgemeine Zustimmungswerte in der Bevölkerung, wird aber mehr und mehr durch lokale Bürgerinitiativen ausgebremst – diese wenden sich vor allem gegen Windkraft- und Netzausbau. In jüngster Zeit hat sich der Populismus des Themas angenommen und inszeniert sich als politischer Arm des Bürgerprotests. In diesem Beitrag wird nach einer kurzen Definition von Populismus die Frage diskutiert, warum Energiewende und Klimaschutz ins Visier der populistischen Kritik geraten konnten, welches populistische Narrativ dazu entfaltet wird und wie sich die Übernahme dieses Narrativs auf die lokalen Energiekonflikte auswirkt. Zwei Haupteffekte stehen dabei im Vordergrund: die inhaltliche Fundamentalisierung der Kritik (entsprechend der ersten populistischen Hauptachse: Elitenkritik) und die formale Radikalisierung der Kritik (entlang der zweiten populistischen Hauptachse: Antipluralismus). Der Beitrag schließt mit einer Diskussion der Risiken, aber auch der Chancen, die sich durch den wachsenden Einfluss des Populismus in diesem Handlungsfeld bieten.

Published: July 2020

AbstractIn this paper, parallel coupled meander lines (PCML) composite right/left-handed transmission line (CRLH-TL) based symmetrical quasi-0 dB coupled-line coupler is presented. Proposed coupler shows measured backward wave coupling level of 0.81 dB at frequency of 6.17 GHz with 3 dB fractional bandwidth (FBW) of 12.64%. Throughout the 3 dB frequency range (5.78–6.56 GHz), isolation and insertion loss of the coupler is better than 24 dB. Overall size of the proposed coupler is 19.6 × 12.1 mm. An equivalent lumped LC circuit model of the coupler is demonstrated. Measured results of the coupler show good agreement with the electromagnetic (EM) simulated and lumped LC circuit model simulated results, which validates proposed coupler design and its performance.
Water sorption hysteresis in wood near 100 °C

Published: July 2020

Abstract
Whether water sorption hysteresis exists above 75 °C and the representation of its relationship with wood softening remains unclear. In this study, sorption hysteresis at three temperature levels, namely, 75, 90 and 99.5 °C, was investigated using accurately controlled conditioning chambers using powder samples from seven wood species. The dry mass loss percentage of the samples and proper equilibrium time was evaluated by pretests to ensure reliable sorption isotherms afterwards. The dry mass loss percentage after the entire sorption isotherm running needs to be kept within 0.5% to avoid complications in determining the equilibrium time. The abrupt increase of equilibrium moisture content at high relative humidity regions and the crossover of adsorption isotherms were not observed. Hysteresis was conspicuous at 75 and 90 °C and was statistically confirmed at 99.5 °C. High sample extractives content or unnecessarily long equilibrium time would cause significant sample dry mass loss, which may suppress the desorption isotherm to an extent that leads to unjustified hysteresis disappearance. The hysteresis behavior observed in this study suggests that wood softening does not necessarily result in hysteresis disappearance, and the explanation of hysteresis progression as a function of wood softening temperature must be evaluated with care in the future.

Published: July 2020

AbstractFew studies of cryogenic treatment were focused on nonferrous alloys, such as magnesium alloy. In this work, the effect of cryogenic treatment (77 K) before extrusion on microstructure and mechanical properties of ZK60 alloy was investigated. The results showed that many fine G.P. zones were formed during the cryogenic treatment and then grew to short fine {\beta }_{1}^{^{\prime} } precipitates when heating before extrusion. These precipitates pinned dynamic recrystallized grain boundaries in the subsequent extrusion, resulting in fine gains and dispersed spherical precipitates. By the cryogenic treatment before extrusion, the extruded ZK60 alloy showed good tensile strength and elongation balance. Especially, elongation was improved by 29%.

AbstractA novel system for contacting gases and liquids, suitable for many applications involving gas–liquid contact such as CO2 capture and brine desalination, has been simulated and experimentally validated. The system comprises a vertical vessel with gas and liquid ports and inert particles that enhance mixing and provide a high gas–liquid interfacial area. A low gas flow rate was statistically demonstrated and experimentally verified to be the optimum condition for CO2 capture and brine desalination; however, the gas velocity can have a considerable effect on the motion of inert particles inside the reactor. Uniform particles motion ensures good mixing within the reactor and hence efficient absorption and stripping process. A computational fluid dynamics (CFD) model, namely Eulerian model, presented in this paper, will help demonstrate the effect of mixing particles at specific conditions on the gas and liquid velocities inside the reactor, gas and liquid volume distribution through reactor, and eddy viscosities stresses of the mixing particles. A mesh-independent study was conducted to demonstrate the independency of mesh structure and size on the output responses. A quasi-steady state was attained to ensure the stability and feasibility of the selected model. The assembled model exhibits remarkable applicability in determining the optimum mixing particles densities, volume ratios, and sizes to ensure best velocity distribution and gas spreading inside the reactor and accordingly enhance the associated chemical reactions.

Published: July 2020

Abstract
The optimal size and location of the compensator in the distribution system play a significant role in minimizing the energy loss and the cost of reactive power compensation. This article introduces an efficient heuristic-based approach to assign static shunt capacitors along radial distribution networks using multi-objective optimization method. A new objective function different from literature is adapted to enhance the overall system voltage stability index, minimize power loss, and to achieve maximum net yearly savings. However, the capacitor sizes are assumed as discrete known variables, which are to be placed on the buses such that it reduces the losses of the distribution system to a minimum. Load sensitive factor (LSF) has been used to predict the most effective buses as the best place for installing compensator devices. IEEE 34-bus and 118-bus test distribution systems are utilized to validate and demonstrate the applicability of the proposed method. The simulation results obtained are compared with previous methods reported in the literature and found to be encouraging.

Abstract

Background
Progressive muscle relaxation (PMR) and autogenic training (AT) are effective relaxation techniques to reduce depressive symptoms. However, no studies on their effectiveness have been conducted among people living with HIV and depressive symptoms. The primary aim of this pilot study was to assess the feasibility and acceptability of PMR and AT interventions among people living with HIV who have depressive symptoms. A secondary aim was to assess the potential effectiveness of these interventions on depressive symptoms and quality of life.

Methods
This study was a three-arm pilot randomized control trial with mixed methods. Participants were randomized to PMR, AT, or a control group (CG), with four assessments (baseline, and at one, three, and six months). The PMR and AT interventions consisted of six 1 h sessions of individual training over 12 weeks, plus home practice. Recruitment, attrition, and completion rates were calculated. Depressive symptoms and quality of life were assessed at all times. Participants' perceptions of the interventions were collected in semi-structured interviews.

Results
Following the screening, 54/63 people met the inclusion criteria, and 42/54 were randomly allocated to the PMR group (n=14), AT group (n=14), and CG (n=14). Six participants (43%; 95% CI 18–71%) in the PMR group and 10 (71%; 95% CI 42–92%) in the AT group completed the intervention. Participants reported better emotion management and improvements in depressive symptoms and quality of life.

Conclusions
The pilot study suggests that a randomized trial to test the effectiveness of these interventions is feasible.

Implementing Frequent Substance Use Testing with Swift-Certain-Fair Sanctions: Stakeholder Insights from a Pilot Program with Volunteer Probationers
Authors: Hunter Sarah B. , Tebeka Mahlet , Kilmer Beau 
Published: July 2020

Abstract
Reducing substance use among individuals subject to community supervision is an important goal for many judges and community corrections officers. Some jurisdictions have had success by ordering justice-involved individuals to frequent substance use testing with swift, certain, and fair (SCF) sanctions for non-compliance. South Dakota’s 24/7 Sobriety program is one example of a SCF program that has also been adopted statewide in Montana, North Dakota, and other jurisdictions. As other entities outside the Great Plains attempt to adopt the 24/7 approach, there is a need to examine how the program is implemented. This paper examines a 24/7-inspired pilot program that was implemented in a southwestern county in the US in 2018. Data on participation rates and testing results for the 6-month pilot program were examined. Using a semi-structured interview protocol with questions that were adapted from the Consolidated Framework for Implementation Research (CFIR) interview guide, we interviewed nine individuals from six stakeholder groups: 1) Court, 2) District Attorney, 3) Public Defender, 4) Probation, 5) Sheriff, and 6) the non-profit organization that administered the testing. There were important differences in how the program was implemented in the county versus South Dakota’s 24/7 program—namely, there was a different target population, participation was voluntary, and testing was conducted in a different setting which increased costs. While county stakeholders decided to discontinue the program after the pilot period, it was able to implement a SCF program and overcome many of the challenges it confronted. There is some interest in exploring implementation of the SCF with those arrested for driving under the influence of alcohol in the county. For jurisdictions considering the implementation of an SCF program, it makes sense to start with a pilot program with pre-determined objectives and timeline for consistency. It is also crucial to hold regular meetings with all relevant stakeholders before and during the pilot to address context-specific challenges. Conducting an implementation analysis of this process based on the CFIR guide can be useful for understanding why the pilot was a success or failure, and how it may be improved.

An approach to ensure joint illumination & communication performance of a forward error corrected indoor visible light communication (VLC) system in presence of ambient light interference
Authors: Chatterjee Sourish , Roy Biswanath 
Published: July 2020

Abstract
In recent time of looming radio frequency (RF) spectrum crisis, visible light communication using lighting infrastructure emerged as a potential alternative at an indoor environment. This paper addresses the setback associated with ambient light interference in an indoor Visible Light Communication (VLC) system to ensure joint communication and illumination performance inside an office room. A novel VLC architecture with suitable white light emitting diode (WLED) luminaire arrangement is presented to minimize the dispersion of signal to interference plus noise ratio (SINR) across the room. Luminaires are categorized in two groups viz. data transmitting illuminants and illuminants for lighting purpose. The first group is dedicated to transmit data as well as serves the purpose of illumination. The other set creates only ambient illumination to achieve quality lighting attributes. The proposed forward error corrected receiver configuration discards the ambient light noise originated by the illuminants that serve the ambient illumination. Tail biting convolutional encoder and viterbi decoder are used at the encoding section of the transmitter and decoding section of the receiver respectively to improve bit error rate. Results obtained through MATLAB simulation shows better average bit error rate (BER) in the order of 10−8 measured at uniformly distributed 25 grid points over the working plane. At the same time achieved average horizontal illuminance with good uniformity comply with ISO recommendation.

Published: July 2020

Abstract

Objectives
Shoulder dystocia (SD) is an obstetrical emergency with well-recognized risk factors. We aimed to identify trends of changes in the specific contribution of risk factors for SD over time.

Methods
A nested case control study comparing all singleton deliveries with and without SD was undertaken. A multivariable logistic regression model was used in order to identify independent risk factors for SD and a comparison of the prevalence and the specific contribution (odds ratio (OR)) of the chosen risk factors in three consecutive eight-year intervals from 1988 to 2014 was performed.

Results
During the study period, there were 295,946 deliveries. Of them 514 (0.174%) were complicated with SD. Between 1988 and 2014 the incidence of SD has decreased from 0.3% in 1988 to 0.1% in 2014. Using a logistic regression model grandmultiparity, diabetes mellitus (DM), fetal weight, and large for gestational age (LGA) were found to be independent risk factors for SD (OR 1.25 95% CI 1.04–1.51, p=0.02; OR 1.53 95% CI 1.19–1.97, p=0.001; OR 1.002 95% CI 1.001–1.002, p < 0.001; OR 3.88 95% CI 3.09–4.87, p < 0.001; respectively). While the OR for grandmultiparity, fetal weight, and LGA has significantly changed during the study period with a mixed trend, the OR of DM has demonstrated a significant linear increase over time.

Conclusions
The individual contribution of selected risk factors for the occurrence of SD has significantly changed throughout the years. The contribution of DM has demonstrated a linear increase over time, emphasizing the great impact of DM on SD.

Fremde gegen Bürger. Zivilgerichtspraxis am Beispiel des Duisburger Notgerichts im 16. Jahrhundert
Authors: Bendlage Andrea 
Published: July 2020

AbstractSince the Middle Ages, hospitable courts played a central role in the complex judicial landscape of the pre-modern age for the conflict resolution of parties of different regional origins, because civil disputes could be dealt with more quickly if at least one plaintiff or defendant was a (legal) stranger. With the obvious relationship between (social) belonging and law established by these courts, questions of asymmetries in law come to the fore, which under the common keywords of inequality, integration and exclusion are a leading interest of research in the history of law, culture and crime, but which have so far hardly been dealt with in research within the framework of civil court practice. The Duisburg Hospitable Court shows that the historical civil proceedings concerning non-repaid loans, undelivered goods or disputed estates were no less important for social stability and order in the pre-modern period than criminal proceedings, even though social integration and exclusion were not the core issues of a civil lawsuit. Since the Middle Ages, hospitable courts concerned themselves with communication and trade practices and at the same time constituted an institution that offered legal security for both foreigners and locals. This was still true in the early modern period, which generally stands for a time that became increasingly hardened towards strangers and people on the move.
Gaming Expertise
Authors: Toft-Nielsen Claus 
Published: July 2020

Abstract
This article argues for an attempt to rethink what counts as gaming expertise. Often, expertise is configured as a fixed and measurable rather than relational capacity – having the necessary level of knowledge with a skill to become expert, or to rise above a particular and objectively defined level of competency. Drawing on interviews with women playing the massively multiplayer online game
Massively multiplayer online games are games capable of supporting large numbers of players interacting, competing and cooperating, as they simultaneously inhabit the persistent open world of the game space.

World of Warcraft, the article argues for an understanding of gaming expertise as a relational, highly contextual capacity, operating and embedded in everyday situations. Through the lens of gaming expertise, the article teases out the complex ways in which gender, technology and identity intersect and are constructed and negotiated in different social contexts.
