Authors: Kaiser Peter , Gruber Hannes , Loth Fanny , Schmidle Gernot , Arora Rohit , Gabl Markus 
Published: August 2019

Abstract
Background Volar locking plates with a central notch were designed to reduce the risk of flexor pollicis longus (FPL) tendon irritation after volar plating for distal radius fractures.
Objective The purpose of this study was to evaluate the course of the FPL tendon after FPL-plate osteosynthesis to identify a plate position that avoids an impingement with the FPL tendon.
Patients and Methods Nineteen patients treated with volar plating using an FPL plate for a distal radius fracture were evaluated. Transverse ultrasound images were used to assess whether the profile of the FPL tendon lied within the plate notch. The position of the FPL tendon on transverse ultrasound images was transferred onto postoperative dorsovolar X-ray images to define an FPL tendon corridor for a plate position not interfering with the FPL tendon.
Results The FPL tendon was aligned inside the plate notch completely in three cases, partially in 11 cases, and missed the notch in five cases. An FPL corridor was defined at the level of the watershed line with all FPL tendons being completely (74%) or partially (26%) aligned inside that corridor. There was a moderate correlation between the plate notch being positioned inside this corridor and the FPL tendon being positioned inside the plate notch (r = 0.49; p = 0.033).
Conclusion It seems advantageous to place the plate notch within a corridor parallel to the radial shaft between the ulnar edge of the scaphoid tubercle and the scapholunate interval for the FPL tendon protection.
Level of Evidence This is Level IV study.

ABSTRACT
Pathogenic bacteria induced sepsis is a risk factor for hospital mortality. Monocyte-derived inflammatory cytokines participate in the sepsis progression. The anti-inflammatory effect of adenine has been previously reported by our laboratory and others. However, the mechanism of action has different opinions and remains unclear in monocyte. Here, adenine was found to significantly inhibit the secretion of lipopolysaccharide-induced inflammatory cytokines such as TNF-α, IL-1β and IL-6 in THP-1 cells. The bioinformatic analysis results showed that the anti-inflammatory function is possibly due to the inhibition of NF-κB signaling. And this result is confirmed by using immunocytochemistry. Moreover, this effect can be suppressed by the AMPK inhibitor. Results also showed that adenine can activate AMPK and its multiple downstream targets. Data from mass spectrometry showed that adenine promotes significant elevation of intracellular AMP. Our data indicate that the anti-inflammatory mechanism of adenine may involve adenine phosphoribosyltransferase-catalyzed intracellular AMP elevation, which stimulates AMPK activation.

ABSTRACT
This study was aimed to investigate the presence of Bacillus coagulans vegetative cells in the intestine and fecal samples in rats fed B. coagulans spores as well as to estimate the ratios of spores and vegetative cells in these samples. A two-step process has been developed to enumerate B. coagulans in different mixed bacterial samples, specifically (1) observation of yellow ring formation on modified GYEA medium upon incubation at 55°C, (2) microscopic examination of spore formation after 7 d of incubation. Our results have demonstrated the presence of vegetative cells in the intestinal and fecal samples in rats fed B. coagulans spores. The ratios of B. coagulans spores and vegetative cells in cecal fluid, colonic content, and feces were approximately 2:8, 2:8, and 4:6, respectively. The existence of B. coagulans vegetative cells improved the intestinal milieu through an elevated short-chain fatty acid concentrations, higher fecal moisture, and lower fecal pH.

Authors: Rubshtein A P , Vladimirov A B , Plotnikov S A 
Published: August 2019

Abstract
CrAlC and CrAlSiC films have been obtained and investigated. Simultaneous sputtering of graphite and Cr05Al05 or Cr035Al055Si0 08 targets was used for films deposition. The structure of the films is amorphous-nanocrystalline. The doping of CrAlC films with silicon is accompanied by an increase in their crystallinity due to the formation of silicon carbide particles. Structural changes make CrAlSiC films harder with a higher resistance to plastic deformation.

Abstract
As part of the construction, thin-layer compositions take loads, work in contact with various environments, and work under influence of physical fields. All this can lead to delamination of the compositions and changes in their mechanical properties. The method of physical modeling of compositions with defects in the form of delaminations is considered. The stiffness properties of thin-layer compositions with local delaminations are studied by experimental-theoretical method.

Published: August 2019

Abstract
Lombok Island was hit by a series of earthquakes in July and August 2018 with magnitude 6 class. This series of earthquakes resulted in fatalities and material losses that even reached Sumbawa Island to the east of Lombok Island. The earthquake was triggered by Flores back arc thrust resulting in ground deformation. Ground deformation can be identified by satellite-based remote sensing method. The Sentinel-1A and Sentinel-1B satellites are two satellites carrying C-band SAR sensors with a temporal resolution of 12 days each for the same orbit, and the difference in time between the two is 6 days. Therefore, ground deformation related to seismo-tectonic or volcanic activities can be identified by interfering two SAR images (interferometric synthetic aperture radar or InSAR) at least in 6 days. By utilizing Sentinel Application Platform (SNAP) a free open source software (FOSS) and combining with other InSAR software, an interferogram that represents line of sight displacement (LOS) between ground and satellite can be generated. Line of sight displacement can then be interpreted as ground deformation signals. It is shown that the series of Lombok earthquake cause an uplift up to 70cm and subsidence up to 25cm. This deformation affects areas around epicentre. A field survey was conducted to obtain information directly and it was seen that the ground deformation that was identified with the InSAR technique were consistent with the findings in the field. This shows the advantages of remote sensing in terms of ability to cover a wide area in a short time.

Authors: Prasetyo Y , Bashit N , Sasmito B , Setianingsih W 
Published: August 2019

Abstract
Climate change has a negative impact on the environment, one of which is the phenomenon of sea level rise. Sea level rise has a devastating effect on marine coastal areas such as shoreline abrasion. Sea level rise has caused a reduction in land, one area on the north coast of Java affected is located in Demak. Demak is a coastal area that has the potential for a shoreline abrasion because of sea level rise and a decrease in the land surface. Monitoring of shoreline changes needs to be monitored in order to find out the magnitude of the shoreline changes and the impact caused by reduced a mainland. One method that can be used to monitor shoreline changes is to use remote sensing technology. Satellite imagery can produce changes in shoreline abrasion without coming to the objects directly. This study aims to assess sea level rise and land subsidence resulting in changes in the shoreline in Demak. The data used are Jason-1 and Jason altimetry satellite data 2, Landsat 7 ETM + satellite imagery in 2011 and Landsat 8 in 2016. Altimetry satellite data is processed to obtain sea level rise on the coast of the Java Sea. Sea Level Anomaly (SLA) data processing uses Inverse Distance Weight (IDW) interpolation. The rise in sea level is determined by the analysis of linear trends from the processing of altimetry satellite data. The separation between water and land boundaries from Landsat satellite imagery uses the band ratio method on Green bands and NIR bands. shoreline changes are calculated using DSAS (Digital Shoreline Analysis System). The results of data processing obtained an average sea level rise in the Java Sea in 2011 to 2016 of + 6.80 mm/year. The highest increase was in Jakarta waters of +11.043 mm / year and the lowest was in Surabaya waters with an increase of +3.85 mm/year. The increase in Semarang waters was + 5.52 mm/year which was used as validation with the tidal data of Semarang. The average change in coastline in the Demak region is -119.08 m. Demak experienced a land subsidence of +2,078 to -8,376 cm/years. The biggest abrasion occurred in Sayung Subdistrict of -691 m. The largest accretion occurred in the District of Wedung + 512.48 m. Based on the results of the increase in water level in the coastal areas of the island of Java and land subsidence that occurred in Demak caused a fairly wide shoreline abrasion.

Abstract
The reduction in the quantity of mangrove forest ecosystems will certainly have a negative impact on the balance of coastal ecosystems, people who live in coastal areas, and of course sustainable sustainable development proclaimed by the local government. The research objective is to analyze the damage of mangrove forest ecosystems through Environmental Science approach. One approach to the study in question is the remote sensing approach. The study was conducted throughout August 2018 precisely at Mampie Beach, Wonomulyo Subdistrict, Polewali Mandar District. The collection of mangrove forest vegetation data was conducted using purposive sampling (systematic plot) technique. The data used in the analysis of damage to mangrove forest ecosystems is the RBI Sheet Polewali Map Scale 1: 50000 BAKOSURTANAL in 1999, SPOT 4 Image in 2014, SPOT 4 Image in 2015, and Digital Globe Image Acquisition 6/9/2016. Data analysis and processing using the Arc-GIS program to analyze SPOT images, overlay and map making using Geographic Information System (GIS) applications, and descriptive analysis for the bio-physical data of mangrove vegetation. Data analysis of mangrove vegetation area in Mampie showed that overall from 1999 to 2016 the area of mangrove coverage experienced a shrinkage of 10.31 ha, namely 35.23 ha (1999) to 24.92 ha (2014). There is one thing that is quite encouraging that in the following year (2015) mangroves in the Mampie area expanded back to 0.58 ha ie to 25.50 ha but shrank back to 0.29 ha the following year (2016). Mampie Beach’s total mangrove area became 25.21 ha. The mangrove forest area in Mampie leaves only a few species of mangrove, the most dominating is Avicennia marina (Forsk.) Vierh.

Abstract
Landsat-8 data (level 1T) received by users are still in digital number and can be used directly for mapping land use / land cover. However, the data still has low radiometric accuracy when it is used to derive information such as vegetation index, biomass, land use / land cover classification, etc. so that so that it requires radiometric / atmospheric correction. In this study, we use atmospheric correction method of the second simulation of satellite in the solar spectrum (6S) and Fast Line-of-sight Atmospheric Analysis of Spectral Hypercube (FLAASH) to eliminate atmospheric influences and compare the results with field measurements. The atmospheric parameters used were aerosol optical depth (AOD), water vapour column and ozone thickness from MODIS data with the date and time of acquisition approaching with Landsat-8 data. From the analysis conducted on the spectral response of atmospheric corrected image shows the 6S model has better accuracy for the spectral response from the rice growth phase compared to the FLAASH model. The analysis of the values of vegetation indices (NDVI, EVI, SAVI and MSAVI) shows that the 6S model has better accuracy for NDVI while for EVI, SAVI and MSAVI the FLAASH model has slightly better accuracy than 6S.

Abstract
Land use classification is the basis for making further policy in many fields including agriculture. Effective methods in landuse/landcover (LULC) classification are essential for later application in policy making. The development of remote sensing technology has been increasing rapidly. The use of Earth Observing (EO) Sentinel-2 imagery can greatly help LULC mapping over large area. As the basic input on the assessment of land availability and suitability, it is important to perform LULC in such way that it is objective, replicable, and accurate. This study aim to performed state-of-the-art Random Forest algorithm on multitemporal Sentinle-2 imagery on LULC extraction over Enrekang Region. With its 10 m spatial resolution as well as multitemporal information, acquired on December as a representation of the rainy season and in July as a representation of the dry season, it is expected to produce a more optimal LULC maps. Confusion matrix were then performed using visually interpreted Pan-sharpened and orthorectified SPOT-6/7 imagery to calculate the accuracy. The output of LULC classification based were expected to reach 95% overall accuracy.
