This study was conducted in the period of 2012 to 2015 in some locations of Japan. At each location, samplings were carried out on reef slopes using SCUBA diving, on reef flats, tidal beaches and river mouths during low tide. The specimens then were treated using a differential interference contrast microscope with a camera lucida (BX-50, OLYMPUS), a quick auto-coater (JFC-1500, Ion Sputtering Device), a scanning electron microscope (SEM) in the laboratory of Shizuoka University.

This paper aims to provide information about the fractions of cadmium (Cd) and its distribution in surface sediment collected from bivalves harvesting areas in Binh Thuan province (Tuy Phong, Phan Thiet, Lagi). For this purpose, the sediment samples were collected monthly along with these areas in 2015–2016. To analyze the fractions of Cd, a five-step Tessier (1979) sequential extraction process was used, including Fraction 1 (Exchangeable), Fraction 2 (Bound to carbonate), Fraction 3 (Bound to iron-manganese oxide), Fraction 4 (Bound to organic compounds), and Fraction 5 (Residual).

The sediment quality assessment showed that trace element concentrations were lower than the limited values in the sediment quality guideline (QCVN 43:2017/BTNMT). According to the Igeo index, the sediments were not polluted by Cu, Pb, Zn, Cr, Fe, and As but were likely polluted by Hg and Mn in some sampling sites. Therefore, it is necessary to invest the future studies to assess the Hg and Mn concentration levels in these sites to protect the marine environment.

This paper suggests the balanced approach of the new two-sided group chain sampling plan (NTSGCh) which operates with four acceptance criteria. The lifetime distribution of Log-logistic is used in this study, and the method of time truncated life test simulation is conducted. The findings proved that the NTSGCh performed better than the NTSCoGCh. Therefore, the NTSGCh is a worthy option for implementation in lot inspection in the manufacturing industry.

In this paper, the research done is about the risk distribution model estimation on health insurance claims using Bayesian. The objective is to derive a health insurance risk model and determine the amount of net premium for each insured age group in health insurance. The sample of this study is the participant of health insurance in the Bandung area, Indonesia, especially for the insured who live in flood-prone areas.

In the study "Distribution, fate and ecological toxicity of some heavy metals in sediment: A case study from Day river downstream, Vietnam" the 50 surface sediment samples were collected along Day River downstream in July 2018 and January 2019 (25 sampling sites) to clarify the status, movement and potential risk of some heavy metals (Cr, Pb, Cu, Cd and Hg). The receptor model of Principal Component Analysis (PCA) was applied to track the source types of these metals.

In this article, we introduced Bayesian Group Chain Sampling Plan (BGChSP) using different combination of parameters. In acceptance sampling plan, the random fluctuations can be describe in the selection of distribution Bayesian approach which is based on prior process history. We apply beta distribution as a suitable prior distribution. By considering consumer’s and producer’s risks, we consider Probabilistic and Indifference Quality Regions for the specified AQL and LQL. For the selection of parameters in BGChSP, Maximum Allowable Percent Defectives (MAPD) is also considered.

In developing acceptance sampling plan, the mean is often the choice due to the fact that it is a good estimator. However, it is only a good estimator when dealing with symmetrical data. If the data is not symmetrical, then the mean is no longer a good estimator, but the median is. The recent two-sided group chain acceptance sampling plans (TSGChSP) has only been applied to Pareto distribution of the 2nd kind by using the mean to cater for symmetrical data. In reality, some data are actually non-symmetrical.

The established modified group chain acceptance sampling plans (MGChSP) only considered the consumer’s risk when developing the plans and turned down the producer’s risk, which means the established MGChSP satisfied the consumer but not the producer. Based on the above problem, this article proposes the minimum angle method for the MGChSP as the method considers both risks (consumer’s and producer’s) simultaneously. In order to develop the proposed MGChSP, the generalized exponential distribution is chosen as its lifetime distribution, and the time truncated simulation is done.

Ebook "Development of an effusive molecular beam apparatus" presents the development of an effusive molecular beam apparatus, which allows the dosing of gases, liquids, and solids in ultra-high vacuum. The apparatus is designed to adsorb precise and reproducible doses to a defined area on metal oxide samples, which is required in Temperature Programmed Desorption and other surface chemistry experiments. The design and the construction of the apparatus is described.
