Abstract
The duration of the VCO oil extraction process affects quality. The centrifugation method produces high VCO quality but requires expensive in investment and operational costs. The acidification method with solar heat was produced VCO, but it took quite a long time (8-12 hours) with the success rate depending on the weather. This study aims to increase the success rate of acidification with a solar heat method through the use of solar heater. It also compares it with the standard of coconut oil quality requirements in SNI 01-2902-2001. The study was conducted in Malonas Village in 2016 involving 15 women farmers. The VCO was analyzed at the BB Pascapanen Laboratory, Bogor. The acidification/chemistry method of VCO was tested in a solar heater and without it. The incubation process is carried out by observing the temperature, yield and drying time. VCO was tested for the percentage content of free fatty acids (FFA), yield, visual and aroma test. The result was decreased in processing time in separation coconut milk to oil, water, and blondo from 8.30 hours ± 0.51 (without solar heater) to 3.45 hours ± 0.16. Oil yield increased by 0.9% and the FFA level was below SNI standard and APCC.

Abstract
Apples are an important source of polyphenolic and most popular fruits worldwide. Due to their phenolic content, consuming apple in a diet tend to low risk and prevention some chronic diseases. The main enzyme is responsible for quality loss, which are affecting by phenolic degradation, are polyphenol oxidase (PPO) and peroxidase (POX). PPO and POX are correlated to the rate of browning with substrate content and enzyme activity. The objective of this research was to investigate the polyphenol oxidase (PPO) and peroxidase (POX) activity in different apple cultivars. Apples Gravin Goldach, Bay 4152, Sonnen Glanz, Gala Mitslugla apples were obtained from an orchad of Hohere Bundeslehranstalt und das Bundesamt fur Wein und Obstbau in Klosterneuburg, Vienna, Austria, then Apple from each cultivar was cut and separated in two parts, peel with seed (red flesh) and peel without seed (white flesh), then PPO and POX were determined. The results showed that tThe highest PPO activity is presented by red flesh of Bay 4152 cultivar, whereas the lowest detected in red flesh Gala Mitslugla. PPO activity on apple flesh of red Bay 4152, white Sonnen Glanz, red gravin Goldach and red Gala Mitslugla were 5.01E+04, 4.79+04, 3.17+04 and 1.91E+04 ΔE/S/Kg protein, respectively. PPO activity on apple flesh was not affected by white or red colour. The highest POX activity was found in red flesh of Sonnen Glanz cultivar, whereas the lowest value was presented in white flesh of Gravin Goldach cultivar varied from 1.07E+05 to 7.68E+04 ΔE/S/Kg protein. In all different flesh of apple cultivars showed that the high or low POX activity was not resulted by the red or white flesh coloured. POX is much higher than PPO activity of all cultivars.

Abstract
Indoor environment conditions of a building are one of the concerned issues as most people usually spend their time inside the buildings. Poor indoor environmental conditions can influence human health in terms of physiological, perceptual and emotional as well. The main objective of this study is to investigate the effect of indoor environmental quality (IEQ) towards occupants’ perception in engineering laboratories/workshops at Mechanical Engineering Laboratories Complex. Thermal comfort and indoor air quality analysis were conducted to evaluate the indoor environment quality of the laboratory/workshop. The analysis consists of physical measurement and subjective measurement. Physical measurements were conducted with occupancy and no occupancy condition while subjective measurement was carried out through the questionnaire. Results show that air-conditioned machine workshop has temperature of 20.8°C which is not within the ASHRAE Standard-55 but still acceptable for occupants. Meanwhile, the thermal condition of non-air-conditioned welding workshop has not complied with the standard in terms of air temperature. In addition, result from occupant’s air odour perception indicates that air odour problem occurred in both case study areas. Based on the findings, indoor environment quality improvement measures are proposed to enhance the indoor environment quality (IEQ) level of the laboratory.

Published: November 2019

Abstract
Acetaldehyde is a toxic mainstream in cigarette smoke. This study aims to apply Ag/TiO2 coated on a polyester air filter (PET) to degrade acetaldehyde. Ag/TiO2 was prepared by doping 10 mol% of silver (Ag) on TiO2 via impregnation method. The crystallinity and wavelength absorption of Ag/TiO2 particles were characterized by X-ray Diffraction (XRD) and UV-vis NIR spectrophotometer, respectively. Then, the Ag/TiO2 particles were mixed with two different binders such as Polyethylene glycols (PEG, Mw = 6,000 g/mol) and Polyacrylic acid (PAA) before coating on PET filter by dip-coating technique. The percentages of binder were varied from 0.3, 1, 3 and 5wt% by weight of photocatalyst particles. The photocatalytic activities of PET filters coated by Ag/TiO2 with different binders were examined by decolorization of 10−5 M methylene blue (MB) solution and degradation of acetaldehyde under visible light irradiation. The XRD results indicated that Ag/TiO2 had the combination of anatase phase, silver oxide (AgO) and metallic silver (Ago). After doping, the band gap energy of TiO2 was reduced from 3.28 eV to 3.22 eV (red-shift effect). The PET filters coated with 5% PEG-Ag/TiO2 and 3% PAA-Ag/TiO2 showed the MB decolorization efficiency of 88 % and 87%, respectively. The photocatalytic degradation of acetaldehyde was carried out by 3%PAA-Ag/TiO2. The degradation efficiency of acetaldehyde by 3%PAA-Ag/TiO2 filter was 96% within 96 h. The concentration of CO2 which was a product of photocatalysis increased simultaneously during the reaction. This was an evidence that acetaldehyde was degraded by the photocatalytic air filter.

Published: November 2019

Abstract
One of the health risks of drivers operating large dump trucks inside open pit mines is exposure to excess whole-body and local vibration, which results in high intensity of work (class 3.3). It is proposed to find sources of excess vibrations by vibro diagnostics in parking tests of dump trucks as influence of external factors (haul profiles, road gradients, etc.) are eliminated in this case. The spectrum of vibrations allows determination of a defect type at high reliability (probability p≥0.9).

Authors: Rathaur Anand Singh , Patel Vinay Kumar , Katiyar Jitendra Kumar 
Published: November 2019

Abstract
In this study, epoxy resin blended with graphite/talc micro fillers are used to fabricate the composite bearing balls of uniform diameter of 12.7 mm. These bearing balls were tested in four ball test rig for investigation of friction and wear. The fabricated composite bearing ball of composition graphite (10 wt%) /talc (10 wt%)/epoxy demonstrated a significant reduction by ∼63% in coefficient of friction and a moderate increment by ∼34% in wear resistance as compared to pure epoxy bearing ball under dry condition. Further, the compressive strength and hardness test were carried out on the composite bearing balls which revealed a reduction in compressive strength after adding the fillers but approximately similar compressive strength and a marginal improvement in hardness by ∼5% was exhibited by graphite (10 wt%)/talc (10 wt%) /epoxy composite bearing ball with respect to pure epoxy bearing ball. Hence, the fabricated polymer composite bearing balls can be implemented for low to moderate load bearing application with enough capability to eliminate the bulk lubrication requirements as in case of conventional metallic bearing balls.

Published: November 2019

Abstract
DKDP crystal is a type of well-known excellent nonlinear optical material that can be used as 2ω, 3ω, and even 4ω harmonic converters. Compared to DKDP crystal, ADP has a larger nonlinear optical coefficient and higher laser damage threshold, so a larger energy and higher conversion efficiency can be expected from ADP crystals. In this paper, a high-quality ADP crystal (118 × 137 × 160 mm) was grown through point-seed rapid growth method within one month. The corresponding optical properties and homogeneity for noncritical phase-matching fourth harmonic generation were investigated. For the ADP sample with cross-section of 110 × 110 mm, the obtained homogeneity noncritical phase-matching temperature is 0.13 °C, which is superior to a DKDP crystal with the same growth parameters. Moreover, UV transmittance property of various thicknesses for ADP crystals was also explored. The transmittance at 263 nm is 88% and decreased 0.36% per millimeter. This result is much lower than the 0.63% for the DKDP crystal in the same thickness range. These results indicate ADP crystals are very promising candidates for noncritical phase-matching fourth harmonic generation.
Distance measures for tumor evolutionary trees
Authors: DiNardo Zach , Tomlinson Kiran , Ritz Anna , Oesper Layla 
Published: November 2019

Abstract

Motivation
There has been recent increased interest in using algorithmic methods to infer the evolutionary tree underlying the developmental history of a tumor. Quantitative measures that compare such trees are vital to a number of different applications including benchmarking tree inference methods and evaluating common inheritance patterns across patients. However, few appropriate distance measures exist, and those that do have low resolution for differentiating trees or do not fully account for the complex relationship between tree topology and the inheritance of the mutations labeling that topology.

Results
Here, we present two novel distance measures, Common Ancestor Set distance (CASet) and Distinctly Inherited Set Comparison distance (DISC), that are specifically designed to account for the subclonal mutation inheritance patterns characteristic of tumor evolutionary trees. We apply CASet and DISC to multiple simulated datasets and two breast cancer datasets and show that our distance measures allow for more nuanced and accurate delineation between tumor evolutionary trees than existing distance measures.

AbstractThere have been some investigations carried out about necrophagous flies and their biodiversity indices in Iran. In the present study, the species composition of flies, their richness, and biodiversity were investigated in central Iran. In a cross-sectional study, specimens were collected monthly in three different climate areas of Qom Province. Species diversity, species richness, and species evenness were calculated to estimate the species biodiversity of flies. In total, 7,291 flies were collected and identified using valid identification keys that classified flies into four families and 15 different species. The largest collection of flies was obtained in the mountainous areas comprising 36.2% of specimens. Moreover, five forensically important species of fly were collected in this region with the potential to cause human and animal myiasis: Calliphora vicina, Lucilia sericata, Musca domestica, Wohlfahrtia nuba, and Chrysomya albiceps. There were slight differences in species richness and diversity indices in the areas. In mountainous areas, the Shannon–Wiener index and richness were maximum (H’ = 1.87, S = 13). The evenness based on the Shannon evenness index in the mountainous areas was 0.728 and 0.719 in desert areas, whereas it was the highest (0.764) in the semidesert areas. Moreover, high values of the Jaccard similarity index were observed in captured necrophagous fly species in all the areas. The necrophagous fly fauna and species diversity indices were high because of an increase in the evenness. In general, some well-known forensically important species of flies were collected that proved the potential of myiasis occurrence in this area.
Lagrangian fluid approach for the modeling of peculiarities of the interstellar dust distribution in the astrospheres/heliosphere
Authors: Mishchenko A V , Godenko E A , Izmodenov V V 
Published: November 2019

Abstract
Interstellar dust penetrates into the heliosphere/astrosphere due to relative motion of the Sun and the local interstellar medium (LISM). Inside the heliosphere/astrosphere and at the heliospheric boundaries, where the solar/stellar wind interacts with LISM, distribution of the interstellar dust is modified due to an action of electromagnetic forces, the solar gravitation and radiation pressure. In this paper we show that the distribution of the interstellar dust particles in the heliosphere has peculiarities of high density layers. In order to understand the nature of the peculiarities Osiptsov’s Lagrangian method has been employed and developed for the case when the force acting on the particles has discontinuity as it is for the electromagnetic force at the helioshperic current sheet. In the result of the modeling we demonstrate existence of multiple layers of high density of the interstellar dust located at 0.03 - 10 AU north and south with respect to the heliospheric current sheet.

AbstractAimThe aim of this study is to assess the association between admission serum albumin and short- and long-term mortality in all hospitalized patients.DesignA single-center cohort study.MethodsA retrospective cohort of all adult hospitalized patients at a tertiary referral hospital between January 2009 and December 2013 were analysed. Admission serum albumin was stratified into six groups: ≤2.4, 2.5–2.9, 3.0–3.4, 3.5–3.9, 4.0–4.4 and ≥4.5 g/dl. The outcomes of interest were in-hospital mortality, length of hospital stay and 1-year mortality. Serum albumin of 4–4.4 g/dl was selected as a reference group for outcome comparison.ResultsA total of 14 075 patients were studied. Admission serum albumin of ≥4.5 g/dl had the lowest in-hospital and 1-year mortality with progressively increased in-hospital mortality observed with decreased admission serum albumin. In adjusted analysis, compared with serum albumin of 4.0–4.4 g/dl, serum albumin of ≤2.4, 2.5–2.9, 3.0–3.4 and 3.5–3.9 were significantly associated with increased in-hospital and 1-year mortality. In contrast, serum albumin of ≥4.5 g/dl was significantly associated with lower 1-year mortality but not in-hospital mortality. Admission serum albumin &lt;4.0 g/dl was significantly associated with a prolonged hospital stay, while admission serum albumin of ≥4.5 g/dl was significantly associated with shorter hospital stay, compared with serum albumin of 4.0–4.4 g/dl.ConclusionLow albumin level at admission was progressively associated with increased short- and long-term mortality in all hospitalized patients even when albumin level was considered in normal range.
