A Methodology for Characterizing the Multiscale Pores and Fractures in Anthracite and Semi-Anthracite Coals and Its Application in Analysis of the Storage and Permeable Capacity of Coalbed Methane
Authors: Fang Huihuang , Sang Shuxun , Liu Shiqi 
Published: May 2019

Summary
Pores and fractures are important components in coal that provide storage space and migration channels for coalbed methane (CBM). To study the importance of pores and fractures to CBM, a combined technique of focused-ion-beam scanning electron microscope (FIB-SEM), X-ray microcomputed tomography (µ-CT), and 3D visualization technology is applied to study the quantitative characterization of multiscale pores and fractures and show their significance for the storage and permeable capacity of CBM. Two high rank coals, anthracite coal (AC) and semi-anthracite coal (SAC), were collected from the southern Qinshui Basin. The results show that two samples show primarily developed organic pores that are filled with minerals. The developmental morphology of the dissolution pores, the shrinkage-induced pores, and the microfractures have important influences on the pore connectivity. The pore connectivity of the SAC sample is poorer than that of the AC sample, and the development of pores and throats is unbalanced. The throats with smaller radii have larger contributions to the volume of the throats. Both samples are beneficial to the adsorption and storage of CBM, but the permeability of the AC sample is better than that of the SAC sample. The porosity of the AC sample is larger than that of the SAC sample, and the microscale pores and nanoscale pores have a larger contribution to the porosity of the SAC and AC samples, respectively. On the basis of the 2D morphology observation, 3D reconstruction analysis, and comparative research of the extracted data, we found that the pore and fracture network of the AC sample contributes more to the storage and permeable capacity of CBM. The introduction and application of the new methodology of the combined technology can enrich the study of multiscale pores and fractures from the nanometer scale to the micron scale and can provide new suggestions for reservoir evaluation in the coal geology sciences.

Abstract
Current multiplexing strategies for massively parallel sequencing of genomic DNA mainly rely on library indexing in the final steps of library preparation. This procedure is costly and time-consuming because a single library must be produced separately for each sample. Furthermore, library preparation is challenging in the case of low-input fixed samples, such as DNA extracted from formalin-fixed paraffin-embedded (FFPE) tissues. Here, we describe CUTseq, a method that uses restriction enzymes and in vitro transcription to barcode and amplify genomic DNA prior to library construction. We thoroughly validate CUTseq and demonstrate its applicability to both genome and exome sequencing, enabling multi-region genome profiling within single stained FFPE tissue sections, to assess intratumor heterogeneity at high spatial resolution. In conclusion, CUTseq is a versatile and cost-effective method for multiplexed DNA sequencing library preparation that can find numerous applications in research and diagnostics.

Published: May 2019

Abstract
Dyeing effluent is a typical refractory wastewater containing toxic pollutants. It is difficult to treat it to meet discharge regulations. The biotoxic effects of pollutants on microorganisms are one of the main constraints on efficient wastewater degradation. The aim of this study was to evaluate biotoxic effects and try to screen toxic substances from dye wastewater. The toxic effects of wastewaters collected at different treatment stages from a wastewater treatment plant in a dye industrial park were determined using bioluminescent bacteria (Vibrio qinghaiensis sp.-Q67). Toxic substances from both influent and effluents were identified by gas chromatography-mass spectrometry. Spearman's rank correlation coefficients indicated significant positive correlations between the toxicity values, and chemical oxygen demand (COD), NH3-N, and total nitrogen (TN). After identifying the toxic levels, phenol, pyridine, and esters were confirmed as the principal organic pollutants in dye wastewater, and increase its toxicity.

LVAD patients with bioprosthetic aortic valve are more prone to leaflet fusion resulting in valvular stenosis and regurgitation. We present a 46 year old patient who had LV systolic function recovery while on LVAD. However, he had a severely stenotic aortic valve bioprosthesis with leaflet fusion that had to be corrected before deactivating his LVAD. Due to high surgical risk, we performed valve-in-valve TAVR with an Evolut CoreValve , however, the patient had significant aortic regurgitation secondary to deployment above the bioprosthetic valve ring. We successfully deployed a second Evolut CoreValve inside the ring with excellent results. This was followed by a successful LVAD deactivation next day. His LV systolic function continued to recover and he had no heart failure symptoms at 3 month follow up. In the right settings, TAVR in recovered LVAD patients with aortic stenosis as bridge to LVAD deactivation is viable option, especially for patients who fall in the high risk group. To the best of our knowledge, this is the first reported case of a valve-in-valve TAVR followed by successful LVAD deactivation in the setting of recovered LV systolic function.

ERROR OF MODELING ECHO SIGNALS FROM EARTH SURFACE ARISING DUE TO DISCRETE ASSIGNMENT OF REFLECTIVE PROPERTIES
Authors: Oreshkina M. V. 
Published: May 2019

The use of discrete distribution of the earth surface reflective properties to simulate echoes leads inevitably to the errors in setting the parameters of the simulated signal. Therefore, there is a problem of choosing the optimal ratio between the intensity of the errors and the sampling frequency, which affects the speed of subsequent echo calculations based on a discrete surface model. To solve this problem, relations linking the statistical characteristics of the errors in specifying the power of echoes with the sample interval of the surface map are obtained. Two approaches are used. In the first case, dependences between the errors of setting the mean value and the variance of the normalized radar cross section and the sample interval are obtained. In the second case, the averaged error values are obtained after interpolating the sampled values. The paper also presents general relations for calculating the error value for the 0–2π angle sector based on the ratios for the sampling interval.
Promoting Small Business Support of Youth Physical Activity in Low-Income, Minority Neighborhoods: Protocol for a Randomized Controlled Trial
Authors: Suminski Jr Richard Robert , Robson Shannon , Turner Jennie , Plautz Eric 
Published: May 2019

Background
An unacceptably high percentage of our nation’s low-income, minority youth (age<18 years) are not regularly physically active. One reason for this could be their lack of access to quality youth physical activity opportunities (YPAOs). Our previous research found that small businesses (<500 employees), which represent over 99.64% (27.9/28.0 million businesses in United States) of all employers, are powerful resources for creating and improving YPAOs. In accordance with the socioecological model and established philanthropic principles, we developed an alpha version of an intervention (alpha-i) for increasing small businesses’ involvement with YPAOs.

Objective
The aims of this proposed study are to (1) create a beta version (beta-i) of the intervention and (2) conduct a pilot study of its impact on small business support for YPAOs and YPAO utilization by the youth in low-income, minority neighborhoods.

Methods
The alpha-i will be refined using information from focus groups and surveys conducted with small business owners and managers, YPAO providers, and parents and guardians of the youths from low-income, predominantly minority neighborhoods. A cluster randomized controlled trial will then be conducted for 1 year to examine the effects of the refined intervention (beta-i) on small business support for YPAOs in 10 low-income, minority neighborhoods. The control group of neighborhoods (n=10) will be provided with a standard practice intervention. The primary outcome for aim 2 will be the percentage of small businesses not supporting YPAOs at baseline that subsequently provide support for YPAOs at follow-up. We also will consider the US dollar equivalent of all types of support (monetary, goods/services, and time) donated for YPAOs by small businesses. In addition, we will examine the impact of the increased small business support for YPAOs on YPAO utilization by the youth.

Results
As of May 1, 2019, all YPAOs and small businesses in the study neighborhoods have been identified, and surveys have begun with these groups. In addition, 9 focus groups were completed, and the data have been transcribed. We anticipate that manuscripts regarding these aspects of the study will be submitted in fall 2019.

Conclusions
The proposed study is significant because it will provide evidence that an easily replicated approach can be used to increase small business support for YPAOs and that this support results in greater use of the YPAOs by youth. A logical next step will be to determine if YPAO changes resulting from increased small business support positively influence youth physical activity levels.

Implementation of Double-Timing Pulse Interpolation Applied to Compact Piston Provers
Authors: Jeronymo C.E. , Araujo S.B. , Aibe V.Y. 
Published: May 2019

This work presents an electronic circuit for double-timing pulse interpolation applied to compact piston provers (also referred as small volume provers). Compact provers are usually employed to prove meters with pulsed outputs. API and ISO standards [1,2] recommend a minimum of 10.000 pulses per run to obtain a resolution better than ± 0.01%. Since the volume of fluid displaced by a compact prover is relatively small, the number of pulses produced during a proving run is often considerably less than 10.000 pulses. Pulse interpolation techniques are commonly used to increase resolution and to diminish uncertainty during a proving run by estimating the fractional part of meter pulses within the time interval of the calibration. In this way, pulse interpolation techniques are essential to obtain accurate flow measurements and to allow the calibration of meters with compact provers.
Our implementation uses a compact piston prover with an internal volume of 12 L and maximum flow capacity of 180 L/min. In order to implement the double-timing pulse interpolation method, we have used a Pentium D, 2.80 GHz installed with a 16-bit counter/timer board. Data acquisition and control software were written using VB .Net. An electronic circuitry was built to activate/deactivate counters gates, and to collect pulses. Some requirements and limitations of pulse interpolation techniques such as circuitry testing and pulse stability are also discussed in this work.

Incerteza de Medição Aplicada a Ensaios de Indentação Pós Fadiga em Colchões e Colchonetes de Espuma Flexível de Poliuretano
Authors: Sosnoski Leandro 
Published: May 2019

Avaliar a qualidade de colchões de espuma flexível de poliuretano condiz com o bem de consumo destinado ao repouso humano, constituído, parcial ou integralmente, por lâminas flexíveis de poliuretano, devidamente revestido. Existem normas para confecção, densidade, deformação permanente à compressão, dentre outras, para que os fabricantes e importadores de colchões mantenham a mesma qualidade dos produtos oferecidos ao consumidor. Estas normas são regidas pela ABNT – Associação Brasileira de Normas Técnicas, onde esta faz referências a todos os itens normalizados que o colchão precisa ter para poder ser comercializado dentro do território nacional.
Este trabalho visa estudar a incerteza de medição no levantamento do comportamento em indentação pós fadiga da espuma para colchões de espuma flexível de poliuretano. Embora existam normas sobre a análise estatística dos resultados, avaliam-se apenas a dispersão no número de ciclos, não considerando fatores como as fontes de incerteza das tensões aplicadas, da máquina de ensaios utilizada.

Test and Simulation Analysis of Tire Inflation Pressure Loss
Authors: Liang Chen , Zhu Xinyu , Wang Guolin , Li Changda 
Published: May 2019

ABSTRACT
Tire inflation pressure loss is inevitable during tire service time. The inflation pressure loss rate (IPLR) is widely used to estimate the inflation pressure retention performance of a tire. However, an IPLR test is a time-consuming process that lasts 42 days for a passenger car tire and 105 days for a truck/bus tire. To perform a thorough study of the tire pressure loss process, based on Abaqus software, a finite element model was developed with tire geometry inputs as well as tire material inputs of both mechanical and permeability properties of the various rubber compounds. A new method—the ideal material method—is proposed here to describe the transient tire pressure loss. Different from the previous isotropic models, the cord–rubber system is described using orthotropic diffusivities, which were determined through air-pressure-drop tests then applied in the finite element model in this article. Compared with the standard IPLR test, the difference between the tire IPLR test and the simulation result is within 5%.

Published: May 2019

Pencemaran minyak oleh kapal tanker merupakan risiko dari usaha minyak dalam menjalankan usahanya. Tuntutan ganti rugi pencemaran minyak oleh pemilik kapal tanker menjadi hal yang diatur secara serius oleh sistem hukum laut internasional melalui konvensi internasional tentang pertanggungjwaban sipil yang terus berkembang menjadi regime internasional tentang pertanggung jawaban dan kompensasi bagi pencemaran minyak (The International Regime on Liablity and Compensation for Oil Pollution Damage). Regime tersebut membagi tiga tingkatan kompensasi (the three tier system compensation) ganti rugi bagi pencemaran minyak sumber dari kapal tanker. Tingkatan kompensasi pertama mendasarkan pada ketentuan CLC 1969 dan IOPC Fund 1971, tingkatan kompensasi kedua mendasarkan pada ketentuan CLC 1992 dan IOPC Fund 1992, selanjutnya tingkatan kompensasi ketiga mendasarkan pada Supplementary Fund Protocol 2003. Tulisan ini bertujuan untuk mengkaji masing-masing tingkatan kompensasi serta posisi Indonesia dalam tingkatan kompensasi ganti rugi. Key words : Regime tanggung jawab dan kompensasi ganti rugi, pencemaran minyak, kapal tanker

Arquitetura do rito: território e identidade indígenas na selva de pedra
Authors: Torres-Londoño Fernando , Righi Maurício G. 
Published: May 2019

Este artigo se organiza como princípio de reflexão sobre o papel central do rito como forma socialmente genética, fonte primeira de resistência cultural e sobrevivência religiosa. No caso dos indígenas brasileiros, o que chamamos de arquitetura do rito revela, em composição singular, sua capacidade ímpar de preservar culturas altamente ameaçadas de extinção. Manter-se culturalmente indígena em grandes metrópoles, como no caso da cidade de São Paulo, implica um envolvimento contínuo com saberes e práticas rituais disponibilizados por pajés. Por meio destes, o indígena se fixa simbólica e fisicamente num território que lhe é cosmologicamente hostil.
