EFFECTS OF FRUCTO-OLIGOSACCHARIDES ON MILK-YIELD AND MILK-COMPONENTS OF DAIRY COWS
Kobayashi, S.,Eida, T. Asian Australasian Association of Animal Productio 1990 Animal Bioscience Vol.3 No.1
Fructo-oligosaccharides are found in many plants, such as onion, burdock and wheat. They are not well hydrolyzed by digestive enzymes in animals, but are peculiarly assimilated by Bifidobacterium and some useful bacteria. In our previous experiment (Kobayashi et al., 1987) it was suggested that they were effective in decreasing energy loss in the metabolism of dairy calves. In the present study, the effects of fructo-oligosaccharides on body weight, milk-yield and milk-components (fat, protein and solids-not-fat) were investigated in dairy cows. Lactating cows were fed a standard diet containing fructoligo saccharides at 18.70g, 9.35g and 0.0g (control) per 100kg body weight, day for three weeks. Neither treatments significantly affected any of the parameters examined. The fructo-oligosaccharides were assumed to be hydrolyzed by rumen microorganisms and hardly to affect the bacterium florae in the intestines of the lactating cows.

Search for sub-GeV dark matter by annual modulation using XMASS-I detector
Kobayashi, M.,Abe, K.,Hiraide, K.,Ichimura, K.,Kishimoto, Y.,Kobayashi, K.,Moriyama, S.,Nakahata, M.,Ogawa, H.,Sato, K.,Sekiya, H.,Suzuki, T.,Takeda, A.,Tasaka, S.,Yamashita, M.,Yang, B.S.,Kim, N.Y.,K North-Holland Pub. Co 2019 Physics letters. Section B Vol.795 No.-
<P><B>Abstract</B></P> <P>A search for dark matter (DM) with mass in the sub-GeV region (0.32–1 GeV) was conducted by looking for an annual modulation signal in XMASS, a single-phase liquid xenon detector. Inelastic nuclear scattering accompanied by bremsstrahlung emission was used to search down to an electron equivalent energy of 1 keV. The data used had a live time of 2.8 years (3.5 years in calendar time), resulting in a total exposure of 2.38 ton-years. No significant modulation signal was observed and 90% confidence level upper limits of 1.6 × <SUP> 10 − 33 </SUP> cm<SUP>2</SUP> at 0.5 GeV was set for the DM-nucleon cross section. This is the first experimental result of a search for DM mediated by the bremsstrahlung effect. In addition, a search for DM with mass in the multi-GeV region (4–20 GeV) was conducted with a lower energy threshold than previous analysis of XMASS. Elastic nuclear scattering was used to search down to a nuclear recoil equivalent energy of 2.3 keV, and upper limits of 2.9 × <SUP> 10 − 42 </SUP> cm<SUP>2</SUP> at 8 GeV was obtained.</P>

Examining the Effects of Metacognitive Instruction in Oral Communication for EFL Learners
Ayako Kobayashi 아시아영어교육학회 2020 The Journal of Asia TEFL Vol.17 No.2
This study investigated the effects of metacognitive instruction in oral communication for EFL learners over a semester. Participants (N = 58) were sampled from four oral communication classes in a private university in the western part of Japan where the researcher had been working as an English instructor. They were freshmen whose majors were not English. The treatment group (n = 28) received metacognitive instruction in oral communication (i.e., they were taught how to improve oral communication skills and how to become more autonomous learners through metacognitive processes as well as activities such as planning, monitoring, and reflecting). The contrast group (n = 30), taught by the same teacher, did not receive metacognitive instruction although they used the same textbooks and materials and had more time for interaction in English. Results of the questionnaire (SRLQ, the Self-Regulated Learning in Oral Communication Questionnaire, Kobayashi, 2016a) showed that students in the treatment group became more self-regulated learners. Moreover, it was found that the treatment group made greater gains in interactional competence, regulation of cognition, cognitive strategies and interaction strategies. Furthermore, it was verified that learners with low interactional competence in the treatment group benefited the most from such metacognitive instruction.

RECENT DEVELOPMENTS IN SOLID LIQUID SEPERATION TECHNOLOGY IN JAPAN
Kobayashi,Kazumasa,Shirato,Mompei,Iwata,Masashi 강원대학교 부설 창강제지 기술연구소 1998 제지기술 Vol.- No.12
There have been many contributions to the improvements and progresses in solid liquid separation technologies in Japan. Fundamental concepts for electro-osmotic dewatering, the design of the automatic recessed-plate-type filter press with both the membrane compression and the electroosmotic devices, and its actual performance will be discussed. The combination of mechanical compression and electroosmosis is effective in removing liquid from sludges for which conventional mechanical dewatering are not successful. Developments of fully automatic filter presses of the plateless-type and the plate-and-frame type, both are available at lower prices, will be introduced. A new centrifugal decanter-type thickener has attained an extremely lower power consumption by using the method of the axial discharge of bath the thickened sludge and separated liquid. A dynamic pulse type spray-dryer is developed basing upon dynamic expression by use of a new pulse combustion engine. A dehydrator with multi rotor-disks multi-axes is developed on a rather unique concept of deliquoring.

ALUMINUM BIAS SPUTTERING FOR FILM COVERAGE IMPROVEMENT
Kobayashi.Shigeru,Shimamura, Hideaki,Sakata, Masao,Fujita, Shouyou,Yajima, Akira,Saito, Hiroshi,Tateishi, Hideki,Sasaki, Shinji 대한전자공학회 1989 ICVC : International Conference on VLSI and CAD Vol.1 No.1
A filter was installed between the sputtering target and the substrate so as to reduce the aluminum deposition arriving with a shallow angle at the substrate in order to study the step coverage improvement by the bias application. It is deduced that the aluminum flowage occurs so that the surface energy is minimized around the via hole. Aluminum films deposited with the pulsed biasing were characterized in which the possible microstructual damage by argon bombardment is to be minimized. This biasing technique should provide with a better process for the step coverage improvement. A sputtering cathode was developed for aluminum bias sputtering which has a substrate current capability as high as 2A for a 5 inch wafer at the substrate voltage around-50V.

Kobayashi, Hironori,Suzuki, Yumiko,Ajimura, Kosei,Konno, Tomonori,Suzuki, Shunji,Saito, Hiroshi The Korean Society of Plant Biotechnology 2011 Plant biotechnology reports Vol.5 No.1
Vitis vinifera cv. Koshu is a traditional grape cultivar that has been grown for centuries in Japan. The Koshu grape has pink-colored skin and Koshu wines have slight astringency. We demonstrated for the first time the characterization of hydroxycinnamic acids, flavan-3-ols, and flavonoids in Koshu grape using high-performance liquid chromatography and liquid chromatography-mass spectrometry. The gross weight of phenolic compounds excluding anthocyanins and proanthocyanidins in Koshu grape at harvest was higher than those in Sauvignon Blanc, Chardonnay, and Merlot grapes. In addition, hydroxycinnamic acid and monomeric flavonol contents in Koshu grape were also higher than those in the other grape cultivars. Transcription analysis of cinnamic acid 4-hydroxylase, p-coumarate 3-hydroxylase, caffeate methyltransferase, and flavonol synthase genes indicated high accumulation of hydroxycinnamic acids and flavonols in Koshu grape skin compared with the other cultivars. These findings obtained by chemical and molecular approaches partially explained the phenolic characteristics and the peculiar astringency of Koshu grape.
