Authors: Karolina Rahmi , Malik Deni 
Published: October 2019

Abstract
This research explains that the use of superplasticizer admixture as an additional material in concrete mixes is expected to minimize concrete damage due to burning at high temperatures by increasing the quality of concrete in its mechanical properties which is compressive strength and physical properties which is concrete porosity. The variations in the addition of superplasticizer admixture used are 1%; 1.5%; and 2%, while variations in concrete combustion are 200°C; 500°C; and 800°C.The test results show a decrease in compressive strength and increase in concrete porosity due to combustion at high temperatures. The tendency of concrete compressive strength will decrease along with the increasing temperature. At the temperature of 200°C, a decrease of 7.14%; 40.57%; and 65.71% occurs, at the 500 °C, decreased by 2.74%; 15.07%; and 65.75%, while at 800°C decreased by 13.79%; 14.47%; and 53.95% of the initial strength of concrete without combustion. The porosity of concrete will rise along with the increasing temperature and the percentage increase will be greater along with the combustion temperature. At the temperature of 200°C there is an increase in porosity of 7.41% - 11,853%, at 500°C increased by 13,334% - 17,779%, and at 800°C increased by 19.26% - 23.704%, from normal concrete porosity.

Abstract
One problem in the development stage of driverless cars on public roads is how to monitor the condition of the vehicle that is affected by different weather and environment, including dry, snowy or heavy rain conditions, which are sometimes difficult to predict and require monitoring systems that should be real-time and accurate. For this reason, an internet of things-based car condition monitoring system is needed to be developed. The development covers three essential parts, which include the development of hardware and digital communication modules, web server development and data analysis and mobile application development for monitoring. The purpose of this study is to design a hardware module needed for car vehicle condition monitoring system; a prototype completed with the onboard diagnostic module and embedded system that will send data to the server in real time. The system was successfully designed and developed using ELM327 and ESP32 with SIM808 for communication module. The benefits of this research are as a tool for asset management of car vehicles both for personal and corporate needs. This study also supports the development of driverless cars that require real-time data input between the vehicle and the server.
Sustainability Assessment of Natural Rubber Primary Processing: A Review
Authors: Sitepu Muhammad Haikal , Matondang Abdul Rahim , Sembiring Meilita Tryana 
Published: October 2019

Abstract
Natural Rubber is an important commodity for the world due to its valuable properties such as good elasticity and renewable. Natural rubber is used to produce various important products such as tire, sport equipment, and medical devices. With increasing demand for these products, the demand of natural rubber is projected to jump in the future. To fulfil this demand, the increasing of natural rubber production is unavoidable. However, to use natural rubber in producing those final products, it needs to flow through primary processing such as crumb rubber manufacturing process, crepe rubber processing and latex centrifuge processing. These processes become source of income for countries such as Indonesia, Malaysia and Thailand as well as citizen of those countries. Despite of these positive impacts, the environmental impacts of natural rubber primary processing such as greenhouse gas emission, waste, high water and energy consumption are identified. Thus, to maintain sustainability, monitoring of sustainability impacts from natural rubber primary processing is necessary. Sustainability assessment is a procedure to evaluate sustainability impacts of products, process and policies. This paper aims to review sustainability assessment process applied in Natural Rubber Primary Processing.

Published: October 2019

Abstract
Concrete is the main material for construction that is widely used throughout the world. The more widespread use of concrete and the increasing scale of development also shows more and more concrete needs in the future. The era development of this rapid globalization era has resulted in the increasing number of used goods/waste whose existence can be a problem for life, one of which is the presence of clamshell ash. For this reason, many things have been done in order to recycle to overcome the problem of the existence of this waste. One of them is that clamshell ash can be used as a substitute for cement in a concrete mixture. This research uses clamshell ash and lime with variations of 0%, 5%, 10%, 15%, and 20% from the use of cement. The substitution of clamshell ash and lime affects the strength of the concrete. There are an increase in slump value with the substitution of clamshell ash by 8,9,11,13,14 and lime substitution by 8,8,5,10,12,13. There are a decrease in compressive strength on the substitution of clamshell ash by 89.18%, 74.09%, 67.87%, 64.92% of normal concrete and compressive strength on lime substitution by 69.84%, 58.53%, 57.05 %, 55.82% of normal concrete. There are a decrease in split tensile strength in the substitution of clamshell ash by 95.96%, 92.3%, 81.7%, 75.8% of normal concrete and split tensile strength on lime substitution by 87.93%, 81.33%, 65, 92%, 48.37% of normal concrete.
Effect of the surface grain refinement on the wear properties of A356/SiC composites
Authors: Yolcu Coşkun , Kahraman Fatih 
Published: October 2019

Abstract
Aluminum alloys are very attractive materials and have a wide application area in industry. However, their weak hardness property requires reinforcement and unavoidable use of particulate composite materials. Nevertheless, mechanical properties of the matrix can be important when sliding conditions are concerned especially wear. Therefore, post treatments can be used to obtain superior matrix properties after reinforcing. In this study, A356 aluminum alloy reinforced by using SiC particles with 5%, 10%, 15%, and 20% mass fractions were manufactured via stir casting process. To examine the effect of the grain refinement on the composites’ wear properties, A356/SiC composite samples were deformed with ultrasonic impact treatment for surface nanocrystallization. Optical microscopy (OM) was used to examine the microstructure, while scanning electron microscopy (SEM) was employed to determine the wear mechanism. Hardness tests and x-ray diffraction were also used to investigate the effect of deformation. Results showed that microstructure contains α-Al dendritic arms and eutectics silicon, and that the porosity increases with rising reinforcement fraction. Upon ultrasonic impact treatment, grains in the microstructure are observed to be oriented through impacts, and the increasing reinforcement fraction is seen to reduce the deformed layer thickness. Further, it is seen that peak broadening occurs, and that hardness values increase as a result of strain hardening upon completion of the treatment. Increasing reinforcement is detected to cause decreased hardened layer thickness, in consistent with microstructure examinations. Furthermore, wear tests showed that increasing reinforcement fraction improves the wear resistance, and that applying the treatment decreases the weight loss during wear tests.

Who Gets to Be in the War Story? Absences and Silences in They Shall Not Grow Old
Authors: Grayzel Susan R. 
Published: October 2019

Abstract
This roundtable offers four diverse perspectives on Peter Jackson’s innovative and controversial World War I documentary film They Shall Not Grow Old (2018). Jackson’s film breaks the mold of the documentary genre in its manipulation and montage of the visual and audio archives held at the Imperial War Museum in London. Yet he puts his technical virtuosity and resources at the service of a very traditional interpretation of the war, focusing almost entirely on the experience of young Englishmen on the Western Front. Scholars Santanu Das, Susan R. Grayzel, Jessica Meyer, and Catherine Robson offer their reflections on both the gains and losses of Jackson’s paradoxical original use of historical documents and old-fashioned rendering of the war’s experiential elements. They consider, respectively, the experience of colonial troops, the place of women in the war, and Jackson’s creative, if controversial, interpretation of the visual and aural archive.
Pharmacologic and clinical assessment of kratom: An update
Authors: White C Michael 
Published: October 2019

AbstractPurposeThis article presents updated information on kratom (Mitragyna speciosa), a natural opioid with stimulant properties that is currently sold in the United States without a prescription.SummaryKratom exerts opioid and alpha-2 agonistic effects, as well as anti-inflammatory and mild stimulant effects. Respiratory depression has not been commonly reported, but kratom does cause a host of adverse effects. While kratom may have a role in patients who are in chronic pain or dependent on opioid painkillers or heroin, this needs to be established in clinical trials. Kratom may have drug interactions as both a cytochrome P-450 system substrate and inhibitor. Kratom does not appear in normal drug screens and, especially when ingested with other substances of abuse, may not be recognized as an agent of harm. There are numerous cases of death in kratom users, but many involved polypharmaceutical ingestions. There are assessments where people have been unable to stop using kratom therapy and withdrawal signs/symptoms occurred in patients or their newborn babies after kratom cessation. Both banning and failure to ban kratom places people at risk; a middle-ground alternative, placing it behind the pharmacy counter, might be useful.ConclusionKratom has a unique pharmacologic profile that might offer advantages over other opioids, but its high abuse liability, potential for drug interactions and adverse events, and inadequate research into the balance of benefits to harm are concerning. There is mounting information on the adverse events associated with kratom use and potential treatments that can be useful to clinicians.
Neuropsychological Performance 1 Year After Status Epilepticus in Adults
Authors: Gramstad Arne , Power Kjersti N , Engelsen Bernt A 
Published: October 2019

Abstract

Objectives
Status epilepticus (SE) may lead to or worsen cognitive dysfunction. Few studies have evaluated magnitude and profile of cognitive dysfunction in patients after SE. Characterization of cognitive deficits may be important for rehabilitation and follow-up. We assessed cognitive function in a consecutive, non-selected group of relatively healthy survivors with a comprehensive neuropsychological test battery.

Methods
A total of 33 patients (24 men, 9 women; mean age 54,9 years, mean education 11,8 years) were tested 1 year after SE with Wechsler Adult Intelligence Scale Fourth edition (WAIS-IV), Rey Auditory Verbal Learning Test, subtests from the Wechsler Memory Scale–Revised, Phonemic and Semantic word list generation, and the Halstead-Reitan Battery. Premorbid IQ was estimated with a Norwegian version of the National Adult Reading Test (NART). Results were compared to published norms. Regression analyses and independent groups t-tests were performed to assess the influence of background variables.

Results
Mean performance generally was about one standard deviation below average. Full scale IQ (WAIS-IV) was significantly reduced compared to estimated premorbid IQ (NART). Negative influence on cognition of brain lesions visible on computed tomography or magnetic resonance imaging and duration of SE &gt;30 min was shown by group comparisons.

Conclusions
SE represents a marker for possible cognitive dysfunction, and follow-up with neuropsychological assessment and cognitive rehabilitation seems warranted in most patients. Complex problem-solving abilities with high general sensitivity to brain impairment showed the most prominent reduction. Otherwise, no specific profile of domain affection was found. Structural brain lesions and duration of SE over 30 min represent risk factors for cognitive deficit.
Nonsurgical Tissue Repositioning: Analysis of Long-Term Results and Patient Satisfaction From 100 Absorbable Suture Suspension Cases
Authors: Few Julius W , Vachon Ginny , Pintas Stephanie , Smith Jesse R 
Published: October 2019

Abstract

Background
Absorbable suspension sutures are the only nonsurgical modality approved for tissue repositioning.

Objectives
To quantitate patient perceptions of treatment at 24 months and determine the impact of age and prior surgical procedures on perceptions of efficacy, treatment longevity, and overall satisfaction. In addition, the authors sought to describe the impact of treatment with absorbable suspension sutures on the likelihood a patient will undergo future surgical procedures.

Methods
The first 100 treated patients who underwent treatment with absorbable suspension sutures, by the senior author, were critically evaluated. Subjects completed surveys 24 months following initial treatment.

Results
Of the initial 100 patients, complete records were available for 80 patients (age 39–86). Eighteen (22.5%) received a second treatment with absorbable suspension sutures and average time to second treatment was 23.4 months (range 13–37 months). Overall satisfaction was affected by age, 100% of patients ≤ 50 vs. 60% of patients &gt; 50 (P = 0.026). Prior surgery appeared to be a factor in patient perception of efficacy: 82.6% of patients with no prior surgery indicated that absorbable suspension sutures were effective vs. 45.5% of patients with a prior surgical procedure (P = 0.0286). Just under one third of pretreatment surgical patients underwent surgery following treatment while 25% of surgery naïve patients went on to have surgery. Importantly, satisfaction with the initial procedure does not preclude later surgery.

Conclusions
Treatment with absorbable suspension sutures is associated with high satisfaction through 24 months and does deter patients from surgery. The combination of lift and volumization results in 4-dimensional rejuvenation that includes rejuvenation of dynamic expression.

Comprehensive evaluation of the MM-GBSA method on bromodomain-inhibitor sets
Authors: Çınaroğlu Süleyman Selim , Timuçin Emel 
Published: October 2019

Abstract
MM-PB/GBSA methods represent a higher-level scoring theory than docking. This study reports an extensive testing of different MM-GBSA scoring schemes on two bromodomain (BRD) datasets. The first set is composed of 24 BRPF1 complexes, and the second one is a nonredundant set constructed from the PDBbind and composed of 28 diverse BRD complexes. A variety of MM-GBSA schemes were analyzed to evaluate the performance of four protocols with different numbers of minimization and MD steps, 10 different force fields and three different water models. Results showed that neither additional MD steps nor unfixing the receptor atoms improved scoring or ranking power. On the contrary, our results underscore the advantage of fixing receptor atoms or limiting the number of MD steps not only for a reduction in the computational costs but also for boosting the prediction accuracy. Among Amber force fields tested, ff14SB and its derivatives rather than ff94 or polarized force fields provided the most accurate scoring and ranking results. The TIP3P water model yielded the highest scoring and ranking power compared to the others. Posing power was further evaluated for the BRPF1 set. A slightly better posing power for the protocol which uses both minimization and MD steps with a fixed receptor than the one which uses only minimization with a fully flexible receptor-ligand system was observed. Overall, this study provides insights into the usage of the MM-GBSA methods for screening of BRD inhibitors, substantiating the benefits of shorter protocols and latest force fields and maintaining the crystal waters for accuracy.

Abstract
Embelia ribes is a traditional Chinese medicine compound used as a remedy for various diseases. Nevertheless, detailed information regarding its chemical composition is unavailable. Herein, ultra-high-performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry was used to characterize the components of E. ribes. A total of 56 compounds, including 16 phenolics, 16 flavonoids, 4 coumarins, 5 fatty acids and 15 other compounds were identified. Furthermore, the total phenolic and total flavonoid content was also assessed; the acetic ether extract of E. ribes was an ideal source of phenolics (308.16 ± 0.00 mg gallic acid equivalents/g of extract) and flavonoids (62.00 ± 0.01 mg rutin equivalents/g of extract). Additionally, acetic ether extract exhibited a high antioxidation effect (ferric reducing activity power: 0.15 ± 0.01 mg/mL; 1,1-diphenyl-2-picrylhydrazyl: 0.18 ± 0.01 mg/mL; 2,2-azino-bis-3-ethylbenzthiazoline-6-sulfonic acid: 0.06 ± 0.01 mg/mL). Further, the nitric oxide concentration in lipopolysaccharide-simulated macrophage RAW 264.7 cells and the pro-inflammatory cytokines (TNF-α and IL-6) were suppressed by acetic ether extract. These findings support the notion that E. ribes is an ideal antioxidant and anti-inflammatory agent.

AbstractBackgroundGuidelines indicate that a low-protein diet (LPD) delays dialysis in severe chronic kidney disease (CKD). We assessed the value of these guidelines by performing a retrospective analysis in our renal clinical practice.MethodsThe analysis was performed from 1 January 2010 to 31 March 2018 in 299 CKD Stage 4 patients followed for 70 months in collaboration with a skilled nutritionist. The patients included 43 patients on a controlled protein diet (CPD) of 0.8 g/kg/day [estimated glomerular filtration rate (eGFR) 20–30 mL/min/1.73 m2 body surface (b.s.)], 171 patients on an LPD of 0.6 g/kg/day and 85 patients on an unrestricted protein diet (UPD) who were not followed by our nutritionist (LPD and UPD, eGFR &lt;20 mL/min/1.73 m2 b.s.).ResultseGFR was higher in CPD patients than in UPD and LPD patients (21.9 ± 7.4 mL/min/1.73 m2 versus 17.6 ± 8.00 mL/min/1.73 m2 and 17.1 ± 7.5 mL/min/1.73 m2; P = 0.008). The real daily protein intake was higher in UPD patients than in LPD and CDP patients (0.80 ± 0.1 g/kg/day versus 0.6 ± 0.2 and 0.63 ± 0.2 g/kg/day; P = 0.01). Body mass index (BMI) was stable in the LPD and CPD groups but decreased from 28.5 ± 4.52 to 25.4 ± 3.94 kg/m2 in the UPD group (P &lt; 0.001). The renal survival of UPD, LPD and CPD patients was 47.1, 84.3 and 90.7%, respectively, at 30 months (P &lt; 0.001), 42.4, 72.0 and 79.1%, respectively, at 50 months (P &lt; 0.001) and 42.4, 64.1 and 74.4%, respectively, at 70 months (P &lt; 0.001). The LPD patients started dialysis nearly 24 months later than the UPD patients. Diet was an independent predictor of dialysis [−67% of RR reduction (hazard ratio = 0.33; confidence interval 0.22–0.48)] together with a reduction in BMI.ConclusionsAn LPD recommended by nephrologists in conjunction with skilled dietitians delays dialysis and preserves nutritional status in severe CKD.
