The Second APOKASC Catalog : The Empirical Approach

We present a catalog of stellar properties for a large sample of 6676 evolved stars with Apache Point Observatory Galactic Evolution Experiment spectroscopic parameters and Kepler asteroseismic data analyzed using five independent techniques. Our data include evolutionary state, surface gravity, mean density, mass, radius, age, and the spectroscopic and asteroseismic measurements used to derive th

Reduced display of conformational epitopes in the N-terminal truncated GAD65 isoform : relevance for people with stiff person syndrome or DQ8/8-positive Type 1 diabetes mellitus

Aims: To investigate whether the N-terminal truncated glutamic acid decarboxylase 65 (GAD65) isoform is as well recognized by people with stiff person syndrome as it is by people with Type 1 diabetes, and whether conformational GAD65 antibody epitopes are displayed properly by the isoform. Methods: GAD65 antibody-positive healthy individuals (n=13), people with stiff-person syndrome (n=15) and chi

Community Perceptions of and Vulnerability to Earthquake Disaster : Insights from the City of Dhaka, Bangladesh

This study is an attempt to empirically determine and analyse the factors that significantly influence the perceptions of and vulnerability to an earthquake disaster that struck a community located in the Hazaribagh area of Dhaka South City, Bangladesh. The empirical results reveal a significant relationship between a number of sociodemographic factors and the community's perceptions of and level

Primary care doctor fostering and clinical research training in Sweden : Implications for Japan

In 2018, a new training program for primary care physicians was launched in Japan. As physicians responsible for the training of new primary care physicians, we have faced many problems, particularly in rural areas. The influence of this new program on primary care physicians in rural areas of Japan has not been sufficiently investigated. The aim of this research was to improve training for primar

Hydration of ionic surfactant micelles from water oxygen-17 magnetic relaxation

Water oxygen-17 relaxation rates have been measured for aqueous solutions of micelles composed of ionic surfactants of varying alkyl chain length, head group, and counterion. The concentration of surfactant and salt was also varied. From these measurements, supplemented with relaxation data for short-chain molecules and with quadrupolar splittings from anisotropic mesophases, we derive structural

A Case Study of Far-Field Temperatures in Progressing Fires

The non-uniform conditions and potential progression of fires in larger spaces calls for modelling methods extending outside of the traditional compartment fire framework. Even though a handful of studies in the area exist there is still little guidance available on how progressing fires in large enclosures can be modelled. Three different methods to calculate far-field gas temperature in large en

Affordances, experimentation and actualization of FinTech : A blockchain implementation study

Blockchain, the technology underlying bitcoin, is an emerging financial technology (FinTech) that is poised to have strategic impacts on organizations. Because it is a new phenomenon, there are few studies on blockchain, and those studies have focused mainly on the technology's potential impacts, whereas how to effectively implement it in an organization remains unknown. Our study intends to fill

The Core of Parents’ Main Concerns When Having a Child With Cataract and Its Clinical Implications

Purpose: To investigate the main concerns associated with being a parent of a child with cataract and how the parents deal with these concerns. Design and method: Twenty-three parents; 6 mothers, 5 fathers and 6 couples with a child with cataract were included in this study. The parents included some with a personal experience of cataract and some without. Data was collected through 17 in-depth in

Social sustainability assessment of groundwater resources : A case study of Hanoi, Vietnam

Groundwater plays a key role in public water supplies around the world, and consideration of the social dimension is a key issue in sustainable groundwater management. In Hanoi, the capital of Vietnam, the situation of groundwater resources is disastrous because the quality has seriously degraded recently. Hence, in this study, a social sustainability assessment framework of groundwater resources

Decomposition approach of the nitrogen generation process : Empirical study on the Shimabara Peninsula in Japan

Groundwater nitrate pollution is one of the most prevalent water-related environmental problems worldwide. The objective of this study is to identify the determinants of nitrogen pollutant changes with a focus on the nitrogen generation process. The novelty of our research framework is to cost-effectively identify the factors involved in nitrogen pollutant generation using public data. This study

Reactive transport column experiment in volcanic ash soil and numerical modelling with anion and cation exchange reactions

Groundwater contamination by nitrate from agricultural fields is a problem shared by many parts of the world. Kagoshima prefecture, Japan, is an important agricultural district experiencing this problem. In this study, laboratory column experiments were performed and a numerical model was developed to improve understanding of nitrate transport process through volcanic ash soils overlying the aquif

Laboratory-scale saltwater behavior due to subsurface cutoff wall

Artificial subsurface barriers are among several countermeasures proposed to control seawater intrusion into coastal aquifers. We performed experimental and numerical studies to investigate the dynamics of residual saltwater trapped in the storage area upon installation of cutoff walls. Experimental results showed that after wall installation, the residual saltwater wedge initially flattened causi

Experimental and numerical study on nitrate transport process through volcanic ash soil

Column experiments using two Japanese volcanic ash soils (Akahoya and Kuroboku soils) were carried out to improve understanding of solute transport characteristics through volcanic ash soil. As the contaminant source, a mixed solution of KNO3 and K2SO4 was applied from the top of the column. Temporal changes of cations and anions in the effluent were measured at prescribed time intervals. Breakthr

Numerical study on saltwater intrusion in a heterogeneous stratified aquifer

In a costal aquifer, saltwater intrusion is frequently observed due to an excess exploitation. There are many researches focused on the saltwater intrusion. However, there are few researches, which take into consideration the mixing processes in a stratified heterogeneous aquifer. In the present study, a laboratory experiment and numerical simulation are made in order to understand the phenomena i

Evaluation of the transition characteristics of macroscopic dispersion and estimation of the non-uniform hydrogeological structure

In general, a natural aquifer has a hydrogeologically non-uniform structure. The movement of pollutants in groundwater is affected by such structural properties during transport by local advection and microscopic dispersion. The macroscopic dispersion coefficient increases linearly with travel distance or travel time at the initial stage after the pollutant is released, and then converges asymptot
