AbstractThis meta-analysis aimed at investigating the impact of oral vitamin C supplementation on the post-procedural recovery of orthopedic patients, including functional outcomes and complex regional pain syndrome type I (CRPS I). Literature search using the Medline, Cochrane Library, and Embase databases from inception till March 2021 identified seven eligible randomized controlled trials with 1,361 participants. Forest plot revealed no significant difference in the functional outcomes at 6–12 months [standardized mean difference (SMD) = −0.00, 95% CI − 0.19 to 0.18, 467 patients], risk of overall complications (RR = 0.98, 95% CI 0.68 to 1.39, 426 patients), and pain severity at 3–6 months (SMD = − 0.18, 95% CI − 0.49 to 0.12, 486 patients) between patients with and without oral vitamin C supplementation. Pooled analysis showed that vitamin C treatment reduced the risk of CRPS I regardless of dosage (RR = 0.46, 95% CI 0.25 to 0.85, 1143 patients). In conclusion, the current meta-analysis demonstrated that oral vitamin C supplementation may reduce the risk of complex regional pain syndrome type I but did not improve the functional outcomes in orthopedic patients. Nevertheless, because of the small number of trials included in the present study, further large-scale clinical studies are warranted to support our findings.

Context. The properties of the population of Galactic supernova remnants (SNRs) are essential to our understanding of the dynamics of the interstellar medium (ISM) in the Milky Way. However, the completeness of the catalog of Galactic SNRs is expected to be only ~30%, with on order 700 SNRs yet to be detected. Deep interferometric radio continuum surveys of the Galactic plane help in rectifying this apparent deficiency by identifying low surface brightness SNRs and compact SNRs that have not been detected in previous surveys. However, SNRs are routinely confused with H II regions, which can have similar radio morphologies. Radio spectral index, polarization, and emission at mid-infrared (MIR) wavelengths can help distinguish between SNRs and H II regions.
Aims. We aim to identify SNR candidates using continuum images from the Karl G. Jansky Very Large Array GLObal view of the STAR formation in the Milky Way (GLOSTAR) survey.
Methods. GLOSTAR is a C-band (4–8 GHz) radio wavelength survey of the Galactic plane covering 358° ≤ l ≤ 60°, |b|≤ 1°. The continuum images from this survey, which resulted from observations with the most compact configuration of the array, have an angular resolution of 18″. We searched for SNRs in these images to identify known SNRs, previously identified SNR candidates, and new SNR candidates. We study these objects in MIR surveys and the GLOSTAR polarization data to classify their emission as thermal or nonthermal.
Results. We identify 157 SNR candidates, of which 80 are new. Polarization measurements provide evidence of nonthermal emission from nine of these candidates. We find that two previously identified candidates are filaments. We also detect emission from 91 of the 94 known SNRs in the survey region. Four of these are reclassified as H II regions following detection in MIR surveys.
Conclusions. The better sensitivity and resolution of the GLOSTAR data have led to the identification of 157 SNR candidates, along with the reclassification of several misidentified objects. We show that the polarization measurements can identify nonthermal emission, despite the diffuse Galactic synchrotron emission. These results underscore the importance of higher resolution and higher sensitivity radio continuum data in identifying and confirming SNRs.

ZusammenfassungDie Symptomatik des thorakalen Bandscheibenvorfalls ist außerordentlich variabel und bereitet nicht selten differenzialdiagnostische Schwierigkeiten. An diese Ursache für die Beschwerden überhaupt zu denken, ist der der wichtigste diagnostische Schritt. Das MRT erbringt dann die endgültige Diagnose. Bei primär radikulären Beschwerden oder leichten Dorsalgien
ohne neurologische Ausfälle ist zunächst eine konservative Therapie zu empfehlen.Ein operatives Vorgehen ist nur beim symptomatischen Patienten indiziert. Die operative Massnahme sollte die ventral lokalisierte Pathologie sicher erreichen und möglichst visualisieren können.

Zusammenfassung
Ziel der Studie Ziel dieser Studie war es, die Empfehlungen eines etablierten ABS-Teams während der wöchentlichen Routinevisiten zu evaluieren sowie ihre Umsetzungsrate und die Gründe der Nichtumsetzung zu untersuchen.
Methodik Die Visiten eines multiprofessionellen ABS-Teams (Infektiologie, Mikrobiologie, Apotheke und Krankenhaushygiene) wurden über 8 Wochen auf 9 intensivmedizinischen und peripheren Stationen eines Universitätsklinikums (1451 Betten) begleitet. Die Empfehlungen des ABS-Teams wurden prospektiv analysiert und bei fehlender Umsetzung Gründe standardisiert von den behandelnden Ärzten erfragt.
Ergebnisse Während des Beobachtungszeitraums fanden bei 262 Patienten 359 ABS-Visiten statt. Im Median nahmen 4 Ärzte und 1 Apotheker (Q25/Q75: 4/6) an den ABS-Visiten teil. Bei 177/359 (49%) ABS-Visiten erfolgte mindestens eine Empfehlung zur Antiinfektivatherapie. Insgesamt wurden 210 Empfehlungen ausgesprochen. Am häufigsten waren mit 38% (80/210) Empfehlungen zur Einhaltung der festgesetzten Therapiedauer. Je mehr unterschiedliche Berufsgruppen an der ABS-Visite teilnahmen, je eher wurde eine Empfehlung ausgesprochen (p=0,016; Odds Ratio=1,018 (1,003–1,033)). 62/210 (30%) der Empfehlungen des ABS-Teams wurden vom behandelnden Arzt nicht umgesetzt. Als häufigster Grund wurde mit 32% (20/62) eine bewusst von der Empfehlung abweichende Therapieentscheidung angegeben.
Schlussfolgerung Die hohe Empfehlungsrate von knapp 50% zeigt den Bedarf an Therapieoptimierung durch ABS-Teams in der Routine. Je multiprofessioneller diese besetzt sind, desto häufiger werden auch Empfehlungen ausgesprochen. Gründe für die fehlende Umsetzung von Empfehlungen sollten kritisch hinterfragt werden – sowohl seitens des ABS-Teams als auch seitens der behandelnden Ärzte auf Station.
Iris yellow spot virus (Iris yellow spot).
Authors:   CRCNPB
Published: April 2021

Abstract

In 1981, de Avila et al. (1981) described a disease characterized by chlorotic and necrotic, eye-like or diamond-shaped lesions on onion scapes (referred to as 'sapeca') in southern Brazil. In 1989, Hall et al. (1993) observed a very similar disease in onion in the USA and detected a tospovirus, which was later shown by Moyer et al. (1993) to be Iris yellow spot virus on the basis of molecular and serological data. In 1998, a new tospovirus was isolated and characterized in the Netherlands from infected iris and leek and named Iris yellow spot virus (IYSV) (Cortês et al., 1998). This virus was subsequently found naturally infecting onion in several major onion-producing states of the USA and around the world (for reviews, see Gent et al., 2006 and Pappu et al., 2009). Gera et al. (1998b) reported that IYSV was responsible for a 'straw bleaching' disease on onion in Israel. In 1999, a 'sapeca' isolate from Brazil was identified as IYSV on the basis of biological, serological and molecular data (Pozzer et al., 1999). In Israel, Kritzman et al. (2000) reported natural IYSV infection of lisianthus grown in the field. IYSV has now been endemic in south-western Idaho and eastern Oregon in onion, leek and chive seed production fields for over 10 years. Losses caused by IYSV can reach 100% in onion crops, for example, in Brazil (Pappu et al., 2009). However, studies in the Netherlands in 2008 showed that latent infections of IYSV were common in onion crops but did not cause economic damage (NPPO of the Netherlands, 2008). Iris yellow spot represents an immediate and serious threat to sustainable and productive onion cropping systems around the world, and the recent detection of this disease in numerous onion-producing countries demonstrates that the disease is spreading rapidly in a range of environments. IYSV is on the EPPO Alert list (http://www.eppo.org/QUARANTINE/Alert_List/alert_list.htm).
Influence of temperature on terahertz waves propagating in magnetized plasma

Published: April 2021

Abstract
The transmission characteristics, including reflectivity, transmissivity and absorptivity, of terahertz waves propagating in high temperature magnetized plasmas are studied numerically and theoretically. The numerical results indicate that the transmission characteristics will be influenced by the wave frequency, electron temperature, plasma density, collision frequency, thickness of plasma and the external magnetic field. It is found that the strength of magnetic field distinctly affects the transmissivity trough and absorptivity peak when terahertz waves penetrate in the plasma. When the electron temperature is higher than 10 keV, the influence of temperature can be observed obviously. These results maybe provide a significative theoretical basis to a certain extent, for the ‘blackout’ communication.

Authors: Sabi’u Jamilu , Tala-Tebue Eric , Rezazadeh Hadi , Arshed Saima , Bekir Ahmet 
Published: April 2021

Abstract
Most of the important aspects of soliton propagation through optical fibers for transcontinental and transoceanic long distances can best be described using the nonlinear Schrödinger equation. Optical solitons are electromagnetic waves that span in nonlinear dispersive media and permit the stress and intensity to stay unaltered as a result of the delicate balance between dispersion and nonlinearity effects. However, this study exploited the Jacobi elliptic method and obtained different soliton solutions of the decoupled nonlinear Schrödinger equation with ease. Discussions about the obtained solutions were made with the aid of some 3D graphs.

Published: April 2021

Abstract
Thermal comfort is a comfort that relates to the room’s temperature conditions such as heat and cold which is manifested from the sensor on the skin and conveyed to the brain. So, the body can adjust the temperature to the surrounding environment. According to the American Standard of ASHRAE 55 of 2009, The purpose of this study is to analyze the suitability of the thermal comfort standard at the At-Taqwa Mosque of the GegerKalong KPAD. The research is conducted by measuring the thermal comfort at the At-Taqwa Mosque. It uses an anemometer measurement tool. The aspects of thermal comfort measured are wind speed, temperature, and relative humidity. The measurement results show that the thermal comfort at the At-Taqwa Mosque is still below the standard. The results of this measurement are simulated on three digital software which are named Sunhour, Flowdesign, and CBE Thermal Comfort. The results of the simulations on these three software show the thermal comfort at the At-Taqwa Mosque doesn’t approve to standard of ASHRAE 55 of 2009 because the highest temperature is on the western exterior area with 33.5 C and the lowest is on the eastern interior area with 23.6 C.

Published: April 2021

Abstract
In open plan office concept, the acoustical distraction problems have become a common problem. Besides, it also needs to deal with thermal issues to have a comfortable work environment. Since the concern of sustainable design is highly discussed, design solutions need to consider energy-saving and environmental health. Commonly sound absorber materials are used to improve acoustics quality. To increase the absorptance, the absorber is installed with air gap and filled with additional insulation e.g. mineral wool. These extra layers potentially give benefit to reduce the thermal transfer when being applied on the envelope walls and ceilings. It is because some of the sound absorber material, air gap, and mineral wool have a low thermal conductivity resulting in lower thermal transfer. This research observes the influences of various sound absorber applications on the acoustics condition and also the impact on the overall thermal transfer value (OTTV and RTTV). The thermal transfer calculation refers to Indonesia National Standard SNI-03-6389-2000, while the rooms acoustics is simulated with Software CATT Acoustics v9 referring to BS EN ISO 3382-3:2012. Absorber materials that been involved are wood wool and PET panel. The result shows that wood wool that applied with 30 mm air gap and additional insulation have reduced the OTTV and RTTV of the room envelope. The initial room condition with Reverberation Time 3.71 second has been reduced to 0.48 second, while OTTV and RTTV are reduced from 48.65 W/m2 and 37.38 W/m2 become 44.24 W/m2 and 14.27 W/m2 respectively.

Published: April 2021

AbstractOne of the efforts to decrease environmental impact due to construction activities is by reducing Embodied Energy in design phase. In the design phase, EE can be associated with the usage of construction materials. On the other hand, the Building Information Modeling (BIM) can be an alternative approach in improving the effectiveness and efficiency material usage. The aim of this paper is to explain how to implement BIM in calculating and reducing the value of EE. The research methodology is a mix qualitative-quantitative method that conducted by using a case study and utilized BIM model of low-cost public apartment. The EE calculation is based on material properties of the BIM model and it also depends on the unit price analysis of each construction works. Furthermore, the Life Cycle Analysis (LCA) method is used to calculate the EE of materials properties value. In order to find the best EE reduction value, a comparison analysis is conducted that it compared the use of conventional materials (as alternative 1) and 2 types of substitution materials there are prefabricated wall panels and concrete masonry unit. Thus, the EE reduction value can be seen and the best low EE material will be used as a reference in the next phase of the construction process.

Abstract
Compulsory education is one of the Indonesian government’s programs in an effort to advance the nation. The compulsory education program can run well if it is supported by right facilities and infrastructure, such as good quality educational buildings. The technical performance of educational buildings can be realized with good quality if the building is designed and built with due observance to the technical standards of a predetermined building. With the same quality of educational buildings in all regions of Indonesia, this study will evaluate the technical performance standards of basic education buildings. The aim of the study was to determine the feasibility level of the technical performance of basic education buildings in Indonesia based on the UNESCO guidelines for school building design in Asia. The study used a qualitative method with a comparative case study approach, namely six basic education buildings in the province of Bali. Those buildings are compared with UNESCO guidelines based on aspects of the environment, teaching spaces and service areas.The results of this comparison are expected to be able to consider more environmental aspects, teaching spaces and service areas in sustainable design, development and maintenance so that the policies applied are localities, such as the use of materials and building methods
Modularity in Design for Disassembly (DfD): Exploring the Strategy for a Better Sustainable Architecture
Authors: Arisya Khalda Fadhilah , Suryantini Rini 
Published: April 2021

Abstract
This paper explores the idea of modularity as one of the important design strategies that potentially creates a circular and more sustainable architecture. Modularity is a common design strategy used to generate form, create spatial efficiency, support mass production and prefabricated design, particularly in modern architecture. However, its contribution to sustainability is rarely discussed. This paper utilises Design for Disassembly (DfD) as a framework to investigate the potential of modularity in design, speculating that such design aspects can potentially minimize waste and improve efficiency in the systematic assembly and disassembly of building components. This paper employs two architectural projects designed with DfD approach as study cases, the Loblolly House and Cellophane House in the USA. The data are taken from works of literature and online secondary sources. The particular building components are mapped based on categories, such as building layers or joints and analysed based on its modular characteristics. The study reveals that the application of modules in particular building layers and separable joints with further use of the division-subdivision operation are significant design strategies found in each case. Such strategies provide better flexibility and interchangeability of building components during the assembly-disassembly process, proven by the calculation of construction waste. These findings arguably expand the discussion of modularity and encourage further study of modular design for a better sustainable architecture.
Analysis of Lighting Performance in the Hall of the Faculty of Engineering, State University of Gorontalo by using the DIALux Evo 9.0 Simulation

Abstract
The need for light in the room is something that cannot be negotiated. Meeting these needs can be obtained through natural lighting and artificial lighting or a combination of both. The purpose of this study is to analyze the performance of natural lighting, especially the daylight factor in the Hall of the Faculty of Engineering, State University of Gorontalo, and provide solutions to improve lighting performance in the room. The research method was carried out through a computer simulation (computer simulation) with DIALux Evo 9.0 software by comparing the existing model and the engineering design model. The latter was carried out by changing the handrail material into transparent material such as glass, adding windows on both sides, and adding light shelves outside and inside the building. The FT Hall room simulation was conducted on September 21 with clear sky conditions within the significant lecture period from 07.00 to 17.00. The simulation results show that the engineering design can increase natural light intensity on the left and right edges compared to the existing conditions, with an average increase of 18%. However, this engineering has not reached the middle of the stands, so that additional engineering is needed to optimize natural lighting. Interestingly, this engineering design reduced excessive light intensity at points A1 and A3 with an average of 847 lux at the existing A1 point, down to 709 lux in the engineering design. Meanwhile, A3, with an average of 653 lux for the existing one, drops to 569 lux in the engineering design. The result shows that the engineering design can optimize the direction of light according to the target point and reduce glare, although additional engineering is still needed.
Thermal performance of reused shipping containers as building components
Authors: Risnandar F F A , Primasetra A 
Published: April 2021

Abstract
The era of disruption occurred influenced by innovations that emerged according to the needs and developments of the times. This occurs in various sectors, including the construction industry sector. One of the growing innovations in the construction industry sector is the reuse of shipping containers (SC) into buildings with various functions. The trend of reusing SC as buildings is quite significant. Several sectors have used a lot of SC as buildings, including: Offices, educational, commercial and residential. However, the reuse of SC as a building has several weaknesses, one of which is the thermal aspect. The structure of the container, which is generally composed of steel, should be considered in achieving indoor thermal comfort. The case study of the paper was SC buildings at Institut Teknologi Sains Bandung (ITSB). The aims of this study were to determine the contribution of design parameters of SC to indoor thermal comfort and its effect on energy efficiency. The method was model simulation on the thermal aspect using Sefaira software. The results showed that setting of design parameters considerably contributed to thermal comfort and energy efficiency.
