Published: July 2019

Abstract
Glycerol is the side product in producing biodiesel. Biodiesel consists of 10% glycerol in average. Methanol, water, soap, salt, catalyst, and matter organic non glycerol (MONG) are found in glycerol as impurities. These impurities effects the concentration of glycerol significantly. Therefore, some treatments are needed to eliminate the impurities. This research is done to find out the effect of acidification mole ratio and solvent volume ratio to the process of purifying glycerol using phosphoric acid in acidification at pretreatment process. This research was started by adding acid to the glycerol to neutralize the alkaline catalyst which was used to break the soap formed become salt and free fatty acid which can be removed from the glycerol easily. Ethylene glycol was used in extraction with 1:0,5; 1:1 and 1:1,5 volume ratio (v/v) and 1:0,1; 1:0,3 and 1:0,5 acidification mole ratio. The MONG contained in the purified glycerol was analyzed with the standard of ISO 2098-1972. The results obtained was the more the volume of solvent used, the less the extraction time needed to gain glycerol with high purity. The highest purity obtained in this research was 92,0382% with 60 minutes of extraction time and 1:1 ratio solvent volume ratio (v/v).

Abstract
Structural actions to reduce floods such as the construction of reservoirs, dikes or dams are considered incapable of fully controlling the floods. Hence, information on flood risks through flood risk map is an obligatory to prevent and minimize losses caused by the floods. Regulation of Minister of Home Affairs no. 33 of 2006 on general guidelines for disaster mitigation states that one of the important things in disaster mitigation is the availability of information and map of disaster prone areas for each type of disaster. This study aimed to determine the potential and risk of flooding in Deli River by integrating software of Hydrologic Engineering Center-River Analysis System (HEC-RAS) with Geographic Information System (GIS). The design debit calculation conducted in four periods, 10, 25, 50 and 100 years. There are four districts, Medan Labuhan, Medan Marelan, Medan Deli and Medan Belawan, discovered as flood-prone areas. 14 sub-districts from four districts are potentially impacted by floods, namely Kota Bangun, Titi Papan, Tanah Enam Ratus, Rengas Pulau, Paya Pasir, Labuhan Deli, Besar, Martubung, Sei Mati, Pekan Labuhan, Nelayan Indah, Belawan Pulau Sicanang, Belawan Bahagia, and Belawan Bahari.

Published: July 2019

Abstract
Business process re-engineering is implemented in this research to provide a new business process in a sugar milling industry in Indonesia. The main reason for this research is inability of the local product to compete with the import one, especially on the price. The price of the local sugar is 25% to 50% higher because of high production cost. Value Stream Map is used in this research to identify the non-value added activities so that its contribution to the total cost can be calculated. The result shows that there are ten activities from five different stations which do not have added value in the process from harvesting to thick syrup product. The cost for those activities contributes to about 34% or IDR 269,574,280 to the total production cost. A new business process is proposed as the result of the business process re-engineering. It is proposed that the new process requires a new technology which is a portable machining system. The result of this new proposed business process is expected to reduce the production cost from IDR 6,500 per kilogram to IDR 2,000 per kilogram.

Authors: Jagadeesh Babu S M. , Kataraki Pramod S. , Narayanaswamy K S. 
Published: July 2019

Abstract
Phase transformations occurring in various metals like steel, titanium and super alloysis integrated and presented in this paper. In steels, the microalloying with Nb and Nb-Mo decrease in transformation temperature indicates the acceleration of transformation kineticsin turn which affect the microstructure and continuous cooling transformation (CCT) diagram. Incase of titanium alloys, the thermohydrogen treatment (THT) uses hydrogen as temporary alloying element which facilitatethe alloys to be processed at lower stresses and/or temperatures. Thermomechanical processing sschedules are designed baseds ons the β transus temperature to produce a variety of novel microstructures. In the case of crystalline materials, plastic deformations assisted by dislocations and the concentration of dislocation increases with increasing plastic strainthus becoming a precursor of twinning.Stress-strain curves for different alloys suggested the microstructural changes account for deformation induced twinning and martensite transformation.

Authors: Nagentrau M. , Tobi A.L.Mohd , Omar A. S. , Ismail M. I. 
Published: July 2019

Abstract
Present study reports the base material preheat treatment effect on microstructure of tungsten carbide (WC) hardfaced carbon steel digester blade which identified as CD blade. Carbon steel blade is located in a digester tank to mix sulphuric acid with ilmenite ore for the process of production. WC hardfacing is deposited on the surface of carbon steel blade to promote its wear resistance as the carbon steel blade is exposed to an abrasive and acidic condition. The influence of base material preheat treatment on microstructure, coating hardness, and elemental composition are the focal point of this work. The effect of base material preheat on hardness value and microstructure of WC hardfacing coating are investigated using hardness test (micro-Vickers) and Scanning electron microscope (SEM) respectively. The base material preheat initiates larger carbide growth in entire coating region and smaller carbide growth in non-carbide region caused by sufficient heat energy. Thus, hardness value of the coating is increased due to uniform distribution of carbides in coating region.

Abstract

BACKGROUND
To investigate the clinical features, management, and outcomes of childhood Takayasu arteritis (c-TA) initially presenting with hypertension.

METHODS
This study retrospectively reviewed medical charts of 96 inpatient c-TA cases from January 2002 to December 2016, with 5 additional patients being prospectively recruited from January 2017 to December 2017. Data were compared between c-TA groups initially presenting with and without hypertension. Blood pressure (BP) control, event-free survival, and associated risk factors were assessed by logistic regression, Kaplan–Meier survival curve, and COX regression models.

RESULTS
The hypertensive cohort (N = 71, 28.2% males) as compared with non-hypertensive cohort had significantly fewer active diseases; fewer episodes of claudication, syncope, blurred vision, and myocardial ischemia; and fewer systemic symptoms (P &lt; 0.05). The hypertensive group presented with more localized abdominal lesions (OR = 14.4, P = 0.001) and limited supradiaphragmatic arterial involvement. Renovascular disease (P = 0.001) and revascularization (P = 0.006) were associated with hypertension. At the median 3-year follow-up, 53% of hypertensive patients achieved BP control and 39% experienced events including vascular complications, flares, or death. The 1-, 3-, 5-, and 10-year event-free survival were 78.7% (95% CI: 65.7%–87.2%), 63.0% (95% CI: 48.1%–74.7%), 48.9% (95% CI: 32.0%–63.8%), and 31.6% (95% CI: 13.8%–51.2%), higher than in non-hypertensive group (P = 0.014). Heart failure, stroke, and body mass index &lt;18.5 kg/m2 were prognostic factors for events. Intervention and baseline systolic BP were independent factors for BP control (P &lt; 0.05).

CONCLUSIONS
Majority of c-TA has hypertension, presenting with a more quiescent disease without typical systemic and/or ischemia symptoms, more localized abdominal lesions, higher proportion of revascularizations and better event-free survival. Three-year BP control is more than 50%. Intervention particularly on renal artery is beneficial for BP control and decreased events.

Artificial intelligence-based multi-objective optimization protocol for protein structure refinement
Authors: Wang Di , Geng Ling , Zhao Yu-Jun , Yang Yang , Huang Yan , Zhang Yang , Shen Hong-Bin 
Published: July 2019

AbstractMotivationProtein structure refinement is an important step of protein structure prediction. Existing approaches have generally used a single scoring function combined with Monte Carlo method or Molecular Dynamics algorithm. The one-dimension optimization of a single energy function may take the structure too far away without a constraint. The basic motivation of our study is to reduce the bias problem caused by minimizing only a single energy function due to the very diversity of different protein structures.ResultsWe report a new Artificial Intelligence-based protein structure Refinement method called AIR. Its fundamental idea is to use multiple energy functions as multi-objectives in an effort to correct the potential inaccuracy from a single function. A multi-objective particle swarm optimization algorithm-based structure refinement is designed, where each structure is considered as a particle in the protocol. With the refinement iterations, the particles move around. The quality of particles in each iteration is evaluated by three energy functions, and the non-dominated particles are put into a set called Pareto set. After enough iteration times, particles from the Pareto set are screened and part of the top solutions are outputted as the final refined structures. The multi-objective energy function optimization strategy designed in the AIR protocol provides a different constraint view of the structure, by extending the one-dimension optimization to a new three-dimension space optimization driven by the multi-objective particle swarm optimization engine. Experimental results on CASP11, CASP12 refinement targets and blind tests in CASP 13 turn to be promising.Availability and implementationThe AIR is available online at: www.csbio.sjtu.edu.cn/bioinf/AIR/.Supplementary informationSupplementary data are available at Bioinformatics online.

Published: June 2019

AbstractWhen related species are distributed in sympatric populations, hybridization may occur. Likewise, one or more of these species may have arisen through historical hybridization between taxa. Here, we aim to elucidate the occurrence of hybridization among three Dyckia spp. (Bromeliaceae) from southern Brazil. We used seven nuclear and six plastid microsatellite loci to assess patterns of genetic diversity, population structure and hybridization in the three species. Furthermore, we performed manual crosses between species to test compatibility and fertility. The results showed that Dyckia julianae has an intermediate molecular profile, low gene flow occurs between Dyckia hebdingii and Dyckia choristaminea and higher gene flow occurs between D. julianae and the other two species. Plastid microsatellites identified 12 haplotypes that are shared among the species. The manual crosses between D. julianae and the other two species produced viable seeds, but no crosses between D. hebdingii and D. choristaminea generated fruits. Our data suggest that the reproductive barrier between D. julianae and the other two species is permeable. Further investigation into the hybrid origin hypothesis of D. julianae should be undertaken, as well as the mechanisms involved in reproductive isolation between D. hebdingii and D. choristaminea.
Gift-giving as a Source of International Authority
Authors: Kustermans Jorg 
Published: July 2019

Abstract
This article discusses the diplomatic practice of gift-giving in the Ancient Near East and Early Modern East Asia. In both cases, gift-exchange served to consolidate the dominant polity’s international authority. The causal relation between gift-giving and authority is typically rendered in terms of generosity inspiring gratitude, but a different mechanism connects diplomatic gift-giving and the consolidation of international authority. Diplomatic gift-giving is a ceremonial form of gift-exchange and it as a ritual practice helps maintain international authority. By means of ritualization, diplomatic gift-exchange renders international authority palatable. Ritualization enables both dominant and subordinate actors to come to terms with the ambiguity of the experience of authority. Subordinate actors are at once entranced and frightened by the authority of the dominant actor. The dominant actor feels both pride and insecurity. By defining an identity as participants in a shared ritual, by orchestrating their demeanor during ritual, and by identifying an external source of the dominant actor’s authority, diplomatic gift-giving contributes to the maintenance of international authority. The ambiguity of the experience of authority is probably irreducible. It is therefore to be expected that any case of ‘international authority’ will feature the performance of similar ritualizing practices.
