In this paper, we classify relatively minimal genus-$1$ holomorphic Lefschetz pencils up to smooth isomorphism. We first show that such a pencil is isomorphic to either the pencil on $P^1\times P^1$ of bidegree $(2,2)$ or a blow-up of the pencil on $P^2$ of degree $3$, provided that no fiber of a pencil contains an embedded sphere (note that one can easily classify genus-$1$ Lefschetz pencils with an embedded sphere in a fiber). We further determine the monodromy factorizations of these pencils and show that the isomorphism class of a blow-up of the pencil on $P^2$ of degree $3$ does not depend on the choice of blown-up base points. We also show that the genus-$1$ Lefschetz pencils constructed by Korkmaz-Ozbagci (with nine base points) and Tanaka (with eight base points) are respectively isomorphic to the pencils on $P^2$ and $P^1\times P^1$ above, in particular these are both holomorphic.

It has been reported that body-weight supported stepping training increases the walking speed of healthy older women. This suggests that stepping with body weight unloading improves the walking ability. We hypothesized that stepping in a sitting position is associated with the physical fitness, walking ability and the physical activity status of older people. PURPOSE: The purpose of this study was to examine the association between the stepping rate (agility) and the muscle strength, balance, mobility and the physical activity status of older women. METHODS: The participants included 108 healthy older women (age: 74±5 years; range: 65-89). The stepping rate, muscle strength (handgrip strength, knee extension strength), balance (one-leg standing time with eyes open), mobility (timed up-and-go test [TUG], maximum walking speed) and physical activity of the participants were measured. The maximal stepping rate in 10 seconds, as measured using an industrial stepping rate counter (Stepping Counter; Yagami), was used as an index of agility. The participants were instructed to perform alternating steps with each leg as quickly as possible for 10 seconds, while in a sitting position. The total number of step for both legs was used as the participant’s score. The physical activity status was measured for two weeks using a uniaxial accelerometer. A multiple regression analysis was used to evaluate the association between the stepping rate and each of the other variables. RESULTS: The stepping rate was 74.8±14.2 (range 34-108) times/10s and was not correlated with age. A multiple regression analysis adjusted for age revealed that the, stepping rate was associated with handgrip strength (β=0.345, p<0.00), knee extension strength (β=0.218, p<0.05), one-leg standing time (β=0.312, p<0.01), TUG (β=-0.239, p<0.05), maximum walking speed (β=0.446, p<0.001) and the percentage of time engaged in low intensity PA (β=-0.245, p<0.05). CONCLUSION: The present study showed the association between agility and muscle strength, balance, walking ability and physical activity of physically independent older women.

The Murotomisaki Gabbroic Intrusion is a sill-like layered gabbro emplaced in sedimentary strata of Tertiary age in southwest Japan. The zoning (including resorption structures) and the compositional variations of plagioclase from throughout the intrusion were studied, and it was found that the zoning pattern may be classified into four types, which may well correlated with the hosting rock types, the mode of occurrences and their stratigraphic positions in the intrusion. The plagioclase zoning was successfully decoded, and the sequence of events that took place during the magmatic differentiation was deduced and further interpreted in the context of a stratified basal...

In this chapter, a triage system using RFID and its experiment are described.Triage is a procedure used by emergency personnel to ration limited medical resources to massive injured people, in which triage tags, are used to 1: classify and transport the injured effectively, and 2: obtain and publish the state and the scale of the casualty incident.We applied RFID tags and mobile devices with a wireless network to speed up 1 and 2 and to make them accurate, and verified the effectiveness through an experiment assuming as massive as 84 injured people, and demonstrated that it even accelerates the transportation of the injured people.

We give an elementary proof of the Mazur-Tate-Teitelbaum conjecture for elliptic curves by using Kato's element.

A series of 6-methyl-3-pyridyl 2-(substituted phenoxy)ethyl ethers and related compounds were synthesized and evaluated against 72-hour old 3 rd-instar larvae of the sllkworm, J ombyx mori, for their activity to induce precocious metamorphosis. A chloro substituent at the 3-position on the benzene ring and chain length of two carbon atoms between the two oxygen atoms were important for this activity. Replacement of 6-methyl-3-pyridyl portion with 3-pyridyl or various substituted pyridyl groups completely eliminated the activity, indicating that the 6-methyl-3-pyridyl ether moiety was indispensable for the activity. Of the compounds tested, 2-(3-chlorophenoxy)ethyl 6-methyl-3-pyridyl ether (1) was the most effective. Precocious metamorphosis induced by compound I was accompanied by the prolongation of the larval period and could be fully counteracted by methoprene, a juvenile horrnone agonist.

Among 1 1 Fagus species (Fagaceae) recorded in the world, only 4 species, Fagus sylvatica, Fagus hayatae, Fagus crenata, and Fagus japonica are known to be galled by Cecidomyiidae (Diptera).

The immobilization technique was applied to improve the productivity of nisin Z, the peptide antibiotic produced by Lactococcus lac tis IO-1. Both entrapment and adsorption methods of immobilization were studied with several kinds of materials in repeated fermentation. The long-term application of natural materials was limited because of the instability of the gel. Low growth rate and low productivity were obtained from the entrapment method due to the improper diffusion of nutrients through the materials. Moreover, the method to entrap the cells with photo-crosslinkable resin prepolyrners caused damage to the cells. The adsorption method showed better results compared with the entrapment method. The adsorption of the cells on porous chitosan beads, Chitopearl SH-251O, gave nisin Z productivity about l. 7 times greater than the free cells. However, during the repeated cultivation a decrease in nisin Z activity was observed. The cells adsorbed on photo-crosslinked resin gel beads, ENTG-3800, produced a greater amount of nisin Z and a lower level of lactate than the free cells with a good operational stability. The nisin Z production tended to increase with repeated cultivation.
