Polymers, Vol 12, Iss 1730, p 1730 (2020)

We prepared ultrathin PFSA/PFSA-vinylon/PFSA laminated electrolyte membranes (thickness = 10 μm) for fuel cells without using a reinforcing material. Nafion and Aquivion solutions were used as PFSA polymers. Vinylon was synthesized by formalizing po

Framework of kit-build concept map for automatic diagnosis and its preliminary use

Autor: Hideo Funaoi, Kazuya Yamasaki, Tsukasa Hirashima, Hiroyuki Fukuda

Publikováno v: Research and Practice in Technology Enhanced Learning

In this paper, we propose a framework of Kit-Build Concept Map (we call it as KB map) where a concept map made by a learner can be diagnosed automatically. In this research, we have divided the task to make a concept map into two sub-tasks: (1) “se

Effects of Combined Practice of Nitrogen Application Regime with Sparse Planting on the Growth and Yield of Rice

Autor: Takao Murata, Eiki Kuroda, Kazuya Yamasaki, Tac Hop Truong, Mitsugu Hirano

Publikováno v: Japanese Journal of Crop Science. 66:551-558

Rice cultivars Akitakomachi and Hitomebore were cultivated in the field using an on-farm developed system ; no basal dressing of nitrogen combined with sparse planting (Exp plots). Their growth and yield were analyzed as compared with rice cultivated

Relationship between gastroprotective effect of locally acting antiulcer agent ecabet sodium and its binding to gastric mucosa in rats

Autor: Hajime Tamaki, Yoshio Kokusenya, Mine Kinoshita, Kazuya Yamasaki

Publikováno v: Digestive Diseases and Sciences. 40:661-667

The present study was designed to examine the relationship between the gastroprotective efficacy of the locally acting antiulcer drug ecabet sodium (ecabet) against ethanol-induced gastric lesions and the amount of the drug bound to the mucosa in com

Study on 'Signal' Constituents for the Evaluation of Animal Crude Drugs. II. Organic Acids

Autor: Hideo Nakai, Kazuya Yamasaki, Yoshio Kokusenya, Tadashi Sato, Akio Hashimoto, Takaaki Miyamoto

Publikováno v: Chemical and Pharmaceutical Bulletin. 43:2195-2199

An analytical method of determining organic acids in animal crude drugs using selective and sensitive postcolumn-pH buffered electroconductivity detection HPLC was established and the organic acid contents in 10 drugs were determined. Nine organic ac

Optical resolution of imidapril hydrochloride by highperformance liquid chromatography and application to the optical purity testing of drugs

Autor: Kazuya Yamasaki, Hiroyuki Nishi, Yoshio Kokusenya, Tadashi Sato

Publikováno v: Journal of Chromatography A. 672:125-133

Imidapril hydrochloride, a newly synthesized angiotensin-converting enzyme (ACE) inhibitor, is administered as a single enantiomer ( SSS -form) because it is the most active of the eight possible optical isomers. Three different approaches to applyin

Investigation of 'Signal' Constituents for the Evaluation of Animal Crude Drugs. I. Free Amino Acids and Total Amino Acids

Autor: Tadashi Sato, Kazuya Yamasaki, Akio Hashimoto, Yoshio Kokusenya, Takaaki Miyamoto

Publikováno v: Chemical and Pharmaceutical Bulletin. 42:1636-1641

The contents of free amino acids (FAA) and total amino acids (TAA; including peptide and protein forms) in 10 animal drugs were determined using precolumn-derivatization high performance liquid chromatography (HPLC). The results showed that the FAA a
