Published: February 2020

Abstract
Indonesia is very vulnerable to flooding due to urbanization of land use, industrialization and made worse by climate change. Sidoarjo is an urban area that frequently experiences regular flooding every year. The flooding break up local traffic, disrupting economic distribution and transportation routes. Minimum information about areas that are often flooded causes a lack of people and government attention to the effects of floods. In this paper, we develop a Fuzzy approach to determine the level of urban flood risk in Sidoarjo. The parameters consist of flood inundation, rainfall, population affected, and drainage. The Fuzzy sets produce fuzzy membership values, and evaluation rules determine the level of flood disaster in each village in Sidoarjo, classified into three levels of vulnerability, they are high, medium and low level of flood vulnerability. Analysis of the results of the calculation of flood risk assessment with Fuzzy multi-criteria decision making (FMCDM) shows a good result with accuracy of 66% compared to the analysis of the Sidoarjo Regional Disaster Management Agency inundation data. However, in reality flood risk is not only caused by inundation factor, the FMCDM method is represented a better assessment in real world. The spatial decision support system using geographical information systems (GIS) provides effective, efficient and useful in flood risk management for local and national governmental agencies.

AbstractIndonesia payment behaviour has turned from traditional to digital as the impact of the technology growth. Digital payment usage in Indonesia have increased rapidly in recent years. Many companies offer this service with different terms and tariff options. Social media is one of the places where people can express their feeling and opinion, including Twitter. In this research, sentiment analysis and opinion mining is conducted to see public satisfaction towards the digital payment service in Indonesia (OVO, GO-PAY and LinkAja). This research is using Twitter data and has several stages, which are data crawling from Twitter, data cleaning, feature selection and classification using two machine learning approach (Naïve bayes classifier and K-Nearest Neighbour or KNN). The raw data is processed to get the clean data, and to get the appropriate feature for classification algorithm and then perform classification and validation to the model. As for the classification algorithm, this research finds out that KNN has better accuracy than Naive Bayes. The result of this research also shows that LinkAja and G0-PAY has more neutral sentiment or customers nearly satisfied of the services provided, and OVO has more negative sentiment than neutral sentiment

Published: February 2020

Abstract
The purpose of this study is to analyze bio-oil composition produced from a low temperature pyrolysis of cooking oils under microwave irradiation. As the feedstock, waste cooking oil (WCO) and fresh cooking oil (FCO) were used. The sample was pyrolyzed at 400°C in a modified microwave reactor with an output power of 900 W. The feedstock was fed into the reactor at 2 ml/min for 60 min under nitrogen gas environment to ensure pyrolysis process. The results showed that the bio-oil compounds of both feedstocks were mainly composed of aliphatic hydrocarbons. Based on carbon number, bio-oil from WCO contained almost 70 wt.% of diesels fraction (C12-C20), slightly lower than FCO which is potential as fuel candidate for diesel engines.

Abstract
Understanding the costs of pavement construction, pavement maintenance, and vehicle operation is essential to planning the management of life cycle and pavement investments, especially under increasing infrastructure demands and limited budget resources. It has long been known that the road user costs (RUC) of vehicle operation are by far the largest component of pavement total life-cycle costs. Those cost are influenced by many factors; one of the most important factor is pavement performance. Pavement condition will have a significant impact on RUC attribute for instance fuel consumption, tier consumption, vehicle maintenance cost, and crew wages. Therefore a study of influence and sensitivity analysis of RUC on difference pavement condition is required. Hence this study is aiming to investigate the sensitivity analysis by varying International Roughness Index (IRI) as pavement performance indicator using the Road User Cost Knowledge System (RUCKS) program. From the research result, with sensitivity equation RUC ($/vehicle-km) = a0 + a1 * IRI + a2 * IRI^ 2 + a3 * IRI^ 3, it is highlighted that IRI has the highest impact on Articulated Truck and Large Bus in terms of transport cost with Sensitivity to Roughness Cubic Polynomial Coefficients a0 1.12958, a1 -0.06418, a2 0.02110, a3 -0.00136.

Abstract
Risks describe as the situation of uncertainty. Risks will appear on every construction project, including an Automated People Mover System (APMS) project. The length of APMS track is 3.05 kilometres to connect Soekarno-Hatta Airport terminals 1, 2 and 3. Track APMS is a bridge structure with a simple concept span. Girder was designed with the PC-V concept. More complex project causes various risks. Therefore, to deliver complex projects to success, the risks should be managed. It is important to handle the risk by applying risk management. Risk management has 3 stages: risk identification, risk analysis and risk response strategy. This research was organized through questionnaire and interview with contractor in APMS project. Risk identification using Risk Breakdown Structure (RBS) method. Then the result of risk identification will analyze using probability and impact matrix. The matrix were aimed to earn the risk category and classified into 3 groups i.e. high, moderate, and low. Risk response strategy is to minimize the impact of risk occurence. This research identified 25 risk factors that consist of 7 category: design risks, time risks, material and equipment risks, financial risks, resources risks, managerial risks and external risks. Delay in relocating existing facilities and girder damage risks are the higest risk, both risk should be avoidance. This study purposed to identification and mitigate risks. These findings were valuable for contractor to mitigate risks especially with the same project characteristics.

Published: February 2020

Abstract
The success factors of project was completing the project without time delay and cost overrun. Time delay and cost overrun were arised due to uncertainty activity during the life cycle project. This may lead the problems to the project. The research aim was analysing cost overrun and time delay in construction project. Data were collected using questionnaire to 36 respondent. 15 factors have been identified in this research i.e land acquisition delay, location of site, support or protest from the local for the project, changes in design specifications, rework, subcontractors and vendors performance, delay in works approval, inaccurate budgeting and resource planning, price escalation of materials, rules and regulations of the government, owners additional required, inflation, payment delay, weak cash flow and bad weather. The result findings, owners and contractors have differences and similarty perception. In cost overrun factors, owner agreed the topmost factor causing was owner additional required while according to the contractors was rework. In delay factors, owner agreed the topmost factor causing delay was inaccurate budgeting and resource planning while according to the contractors was land acquisition delay. Nevertheless, both parties agreed the inflation has a least influent to construction project delay.

Published: February 2020

Abstract
In areas that have not been 100% flowed by government piped water sources, residents must look for other water sources leastwise flow in time whenever people need water. A similar situation occurred in the study area, Kemijen and Tambak Lorok, two low income kampung in the coastal area of Semarang City that located adjacently. About 90% of households in Kemijen use government piped water sources, while nearly 100% of Tambak Lorok use ground water piped provided by neighborhood private sector. However, the Kemijen community does not necessarily get proper access because the government piped water could not flow the water all of the time, while private groundwater in Tambak Lorok can do. This study explores the gap of water provision in Kemijen and Tambak Lorok, as the provision of groundwater service is not a sustainable method so it should be replaced by the government provision in the future. In that context, the gap could be seen as the challenge for the government provision in improving their quality of service in the future. The study uses is a combination of qualitative and quantitative method and descriptively analysis in comparing the water provision system in the two kampung.

Abstract
Rolled Zn-0.8Li-0.2Ag(wt%) alloy as candidates for biodegradable materials. The biodegradable behavior of Zn-0.8Li-0.2Ag alloy in different solutions (Ringer’s, DMEM, SBF and DMEMp) was investigated. The cytotoxicity of Zn-0.8Li-0.2Ag alloy and its antibacterial properties against staphylococcus aureus, enterobacter faecalis and candida albicans were evaluated. The results showed that Zn-0.8Li-0.2Ag alloy consists of zinc matrix and a LiZn4 secondary phase. The presence of Cl− causes locally corroded of Zn-0.8Li-0.2Ag alloy in Ringer’s solution, and its corrosion resistance is lower than that of the alloy which is uniformly corroded in other solutions containing CO3
2− and PO4
3−. Zn-0.8Li-0.2Ag alloy is non-toxic and exhibits better antibacterial properties than the experimental reference group without silver.

Abstract
The graphene oxide(GO)/polyacrylic acid(PAA) was prepared by in situ polymerization in graphene oxide lamellae, and crosslinked graphene oxide/polyacrylic acid complex(CLGO/PAA) was formed by esterification reaction between 1,4-butanediol and carboxylic acid of PAA at same time. The CLGO/PAA aerogel was prepared by freeze drying method. The CLGO/PAA aerogel has good stability and high saturated adsorption capacity for the adsorption of Pb(II) ions in water. The structure and properties of the CLGO/PAA aerogel were characterized by using x-ray diffractometry(XRD), field emission scanning electron microscopy (FESEM), infrared spectroscopy(FT-IR), and atomic absorption spectrometer(AAS), respectively. The results show that the prepared CLGO/PAA aerogel possess elliptical pore structure. In addition, the adsorption properties of the CLGO/PAA aerogel for Pb(II) in water were studied under different pH, different concentrations of Pb(II), contact time and number of adsorbent cycles. The results show that the adsorption amount of Pb(II) could reach to 640 mg g−1 at the initial concentration of Pb(II) was 500 mg l−1, and the adsorption equilibrium could be reached after 60 min. The adsorption amount for Pb(II) was still 143 mg g−1 after 5 times cycle.

Abstract
We report on a rapid method to synthesize gold nanobipyramids that utilizes a hexagonal liquid crystal as a frame, suggesting a liquid crystal accelerated growth process. The method represents an improvement in processing time as compared to previously reported methods. Furthermore, as the bulk of the total processing time is required by a purification step, the method presented in this paper holds the promise of an order of magnitude improvement of processing time by further optimization of the growth process that would eventually eliminate the need for purification.

The first objective of this paper was to perform a comparative analysis of different fabrication variables (e.g., particle size, shape, morphology, chemical composition, structure, purity of starting materials, homogeneity, annealing, and synthesis methods) on the overall MCE properties of the aforementioned family. In addition, the best fabrication practices for further improvement in MCE properties are proposed. The second objective was to observe different material’s doping (e.g., Cr, Si, Ge, B) in hysteresis loss mitigation and MCE properties enhancement. Best doping materials were suggested for the compositions, which were displaying optimum MCE properties for further MCE enhancement. Lastly, but most importantly, to propose a high performing magnetic refrigerant by: (1) shortlisting a composition with optimum MCE properties; (2) further enhancement in MCE through adopting best fabrication processes for the said magnetic refrigerant; (3) suggesting best doping material for hysteresis loss mitigation and MCE enhancement; and most importantly (4) fabricating the proposed magnetic refrigerant as a nanostructure; thus, improving MCE properties through broadening of T

Authors: Horing Norman J M , Mancini Jay D 
Published: February 2020

Abstract
This work is concerned with determination of the thermal and magnetic behavior of the Group VI Dichalcogenides in a quantizing magnetic field. Our discussion includes analysis of the Grand Potential, Helmholtz Free Energy, partition functions (grand and ordinary) and the entropy and specific heat: their dependencies on temperature and magnetic field strength are carefully examined, particularly in the degenerate regime and the approach to zero temperature. The joint dependence on magnetic field and temperature is also determined for the Dichalcogenide magnetic moment in the degenerate statistical regime, replete with de Haas–van Alphen (dHvA) oscillatory phenomenology and also above the zero–temperature limit.
Implications for medication dosing for transgender patients: A review of the literature and recommendations for pharmacists

Published: February 2020

Abstract

Purpose
Transgender patients face considerable healthcare disparities. Improved means of recognizing transgender patients and understanding their medical needs is important to provide optimal care. The electronic medical record (EMR) of our health system allows for differentiation of gender identity, legal sex, and sex at birth. With EMR recognition of transgender patients, a recommendation for estimating creatinine clearance (CLcr) and ideal body weight (IBW) was needed to standardize medication dosing.

Summary
The literature was reviewed for evidence on the effect of gender-affirming hormone therapy on serum creatinine concentration and lean body mass. Findings informed a recommendation for drug dosing based on CLcr and IBW in transgender patients. Four studies that reported the effect of hormone therapy on biometric laboratory values were found. Three studies reported that values of transgender patients more closely resembled the standard values of their gender identity vs sex at birth after hormone therapy; 1 study reported a range of values that more closely resembled those associated with sex at birth while still overlapping with values associated with gender identity. Consequently, it was recommended that pharmacists dose medications based on CLcr and IBW calculations consistent with gender identity after a patient has been on hormone therapy for 6 months or longer.

Conclusion
Providing optimal care to transgender patients includes considering the effect of gender-affirming hormone therapy on overall physiology. Consistently using the appropriate CLcr and IBW calculations for each patient ensures safe and effective care. Additional studies are needed to confirm the effect of hormone therapy on renal clearance and lean body mass.
Estimating Respirable Dust Exposure from Inhalable Dust Exposure
Authors: Wippich Cornelia , Rissler Jörg , Koppisch Dorothea , Breuer Dietmar 
Published: February 2020

AbstractIn the sector of occupational safety and health only a limited amount of studies are concerned with the conversion of inhalable to respirable dust. This conversion is of high importance for retrospective evaluations of exposure levels or of occupational diseases. For this reason a possibility to convert inhalable into respirable dust is discussed in this study. To determine conversion functions from inhalable to respirable dust fractions, 15 120 parallel measurements in the exposure database MEGA (maintained at the Institute for Occupational Safety and Health of the German Social Accident Insurance) are investigated by regression analysis. For this purpose, the whole data set is split into the influencing factors working activity and material. Inhalable dust is the most important predictor variable and shows an adjusted coefficient of determination of 0.585 (R2 adjusted to sample size). Further improvement of the model is gained, when the data set is split into six working activities and three material groups (e.g. high temperature processing, adj. R2 = 0.668). The combination of these two variables leads to a group of data concerned with high temperature processing with metal, which gives rise to a better description than the whole data set (adj. R2 = 0.706). Although it is not possible to refine these groups further systematically, seven improved groups are formed by trial and error, with adj. R2 between 0.733 and 0.835: soldering, casting (metalworking), welding, high temperature cutting, blasting, chiseling/embossing, and wire drawing. The conversion functions for the seven groups are appropriate candidates for data reconstruction and retrospective exposure assessment. However, this is restricted to a careful analysis of the working conditions. All conversion functions are power functions with exponents between 0.454 and 0.946. Thus, the present data do not support the assumption that respirable and inhalable dust are linearly correlated in general.
Automatic Attention Capture by Threatening, But Not by Semantically Incongruent Natural Scene Images

Published: February 2020

Abstract
Visual objects are typically perceived as parts of an entire visual scene, and the scene’s context provides information crucial in the object recognition process. Fundamental insights into the mechanisms of context-object integration have come from research on semantically incongruent objects, which are defined as objects with a very low probability of occurring in a given context. However, the role of attention in processing of the context-object mismatch remains unclear, with some studies providing evidence in favor, but other against an automatic capture of attention by incongruent objects. Therefore, in the present study, 25 subjects completed a dot-probe task, in which pairs of scenes—congruent and incongruent or neutral and threatening—were presented as task-irrelevant distractors. Importantly, threatening scenes are known to robustly capture attention and thus were included in the present study to provide a context for interpretation of results regarding incongruent scenes. Using N2 posterior-contralateral ERP component as a primary measure, we revealed that threatening images indeed capture attention automatically and rapidly, but semantically incongruent scenes do not benefit from an automatic attentional selection. Thus, our results suggest that identification of the context-object mismatch is not preattentive.
The growing pains of ifosfamide
Authors: Sprangers Ben , Lapman Sebastian 
Published: February 2020

AbstractIfosfamide is a commonly used chemotherapeutic known to have numerous adverse kidney manifestations. In this issue of Clinical Kidney Journal, Ensergueix et al. report a multicentric observational retrospective French study on 34 adult patients with tubular dysfunction and /or kidney dysfunction following ifosfamide treatment. Of these patients, 18% had isolated proximal tubular dysfunction, 14% had isolated acute kidney injury (AKI), 18% had isolated chronic kidney disease (CKD) and 50% had a combination of proximal tubular dysfunction and AKI. Concomitant treatment with cisplatin was identified as a risk factor for the development of AKI, and cisplatin and age were associated with estimated glomerular filtration rate at last follow-up. Interestingly, the cumulative dose of ifosfamide was not associated with renal outcomes. This report highlights the need for additional studies on the prevalence, spectrum and management of ifosfamide-associated nephrotoxicity and clearly demonstrates that patients who received ifosfamide should be followed long term to detect proximal tubular dysfunction and CKD early.
