In the Large Helical Device (LHD), some reactor-oriented experiments, i.e. high beta, high ion temperature, steady state operation, have produced remarkable progress in recent experimental campaigns. By optimizing the rotational transform, an average beta value of 4.3 %, which is the highest on record for helical devices, was achieved. The ICRF sustained steady-state discharges for more than 30 minutes, these were also successfully performed with the aid of the magnetic axis swing technique for the reduction of the heat load to the plasma-facing component. In the discharge, the total input energy to the plasma reached 1.3 GJ, which also established a new record.1
Effects of Vitamin A on Carcass Composition Concerning Younger Steer Fattening of Wagyu Cattle
Nade, T.,Hirabara, S.,Okumura, T.,Fujita, K. Asian Australasian Association of Animal Productio 2003 Animal Bioscience Vol.16 No.3
Regarding the fattening of younger cattle that the Ministry of Agriculture Forestry and Fisheries (MAFF) recommends in Japan, this study looked at vitamin A control in feed and blood and its effect on performance of production and carcass composition of Wagyu steers. Five sets from 10 Wagyu artificial identical twins were divided to into 2 groups, a restricted group (Test) and a supplied group (Control). The body weight at the finishing time of the Test was significantly lower than that of the Control (p<0.05). The daily gain from 13 to 21 months old, as the animals in the Test were fed the concentrated feed without Vitamin A, was significantly different (p<0.05) between the Test and the Control. The total daily gains for the Test and the Control for the fattening period were 0.82 kg/day and 0.93 kg/day, respectively, which showed a significant difference (p<0.01). Regarding the rib thickness, the Test was thinner than the Control. The Beef Marbling Scores of the Test and Control were 3.60 and 2.80, respectively. The muscle weight of the Test was significantly smaller than that of the Control (p<0.01). However, regarding the ratio to the carcass, the Test was significantly higher than the Control (p<0.05). For the fat weight, the Test was smaller by about 15 kg than the Control (p<0.01). Furthermore, for the fat ratio to the carcass, the Test was significantly lower than the Control (p<0.05). The bone weights of the two groups were approximately the same. Regarding the ratio of bone to carcass, the Test was higher than the Control (p<0.01). For the younger fattening method, the low level vitamin A in the serum had the effect that the muscle ratio to the carcass weight was greater and the fat was less, but the carcass and muscle weight were less.

Omatsu, T.,Kong, H.J.,Park, S.,Cha, S.,Yoshida, H.,Tsubakimoto, K.,Fujita, H.,Miyanaga, N.,Nakatsuka, M.,Wang, Y.,Lu, Z.,Zheng, Z.,Zhang, Y.,Kalal, M.,Slezak, O.,Ashihara, M.,Yoshino, T.,Hayashi, K.,T Cambridge University Press 2012 Laser and particle beams Vol.30 No.1
<B>Abstract</B><P>The current trends in stimulated Brillouin scattering and optical phase conjugation are overviewed. This report is formed by the selected papers presented in the “Fifth International Workshop on stimulated Brillouin scattering and phase conjugation 2010” in Japan. The nonlinear properties of phase conjugation based on stimulated Brillouin scattering and photo-refraction can compensate phase distortions in the high power laser systems, and they will also open up potentially novel laser technologies, e.g., phase stabilization, beam combination, pulse compression, ultrafast pulse shaping, and arbitrary waveform generation.</P>

The NCT Program, in which the present JT-60U is being modified into a superconducting coil machine, is discussed under nationwide collaboration in Japan. Its mission is to establish high-beta steady-state operation for DEMO and to contribute to ITER. NCT is designed to have potential to investigate such research.

This study was conducted to determine the relationships between abdominal temperature (Tabd) and some thermoregulatory responses, such as heat production (HP), heart rate (HR), respiration rate (RR), temperature of external ear tract (Tee), comb surface temperature (Tcs) and shank skin temperature (Tss), for revealing the role of deep body temperature in the thermoregulation of broiler chickens. Tabd was divided into 5 zones of 40-41, 41-42, 42-43, 43-44 and $44-45^{\circ}C$, and maintained for 3 hours in each zone by varying environmental temperature from 11 to $33^{\circ}C$. HP and HR had a greater increase with Tabd above $42.5^{\circ}C$. RR increased markedly with Tabd above $41.5^{\circ}C$, and reached a maximum when Tabd was at $42.5^{\circ}C$, then began to decrease. In addition, HP and HR increased significantly with decrease RR during the decreasing phase of panting. Tcs and Tss changed rapidly with Tabd when Tabd was below $41.5^{\circ}C$, and increased more slowly above $41.5^{\circ}C$. Tee was lower than Tabd, and its increase was less than that of Tabd. These results suggest that changes in thermoregulatory responses are induced by an increase in abdominal temperature. Tabd increases to adjust the ratio of sensible and evaporative heat loss when Tabd is below $42.5^{\circ}C$, while the ability in body temperature regulation gradually disappears when abdominal temperature exceeds $42.5^{\circ}C$ and heat balance can not be maintained.
Fine structure of the isoscalar giant quadrupole resonance inSi28andAl27
Usman, I. T.,Buthelezi, Z.,Carter, J.,Cooper, G. R. J.,Fearick, R. W.,Fö,rtsch, S. V.,Fujita, H.,Fujita, Y.,von Neumann-Cosel, P.,Neveling, R.,Papakonstantinou, P.,Pysmenetska, I.,Richter, A.,Roth American Physical Society 2016 Physical Review C Vol.94 No.2
<P>The isoscalar giant quadrupole resonance in Si-28 and Al-27 has been investigated with high-energy-resolution proton inelastic scattering at E-p = 200 MeV and at scattering angles close to the maximum of Delta L = 2 angular distributions with the K600 magnetic spectrometer of iThemba LABS, South Africa. Characteristic scales are extracted from the observed fine structure with a wavelet analysis and compared for Si-28 with random-phase approximation and second random phase approximation calculations with an interaction derived from the Argonne V18 potential by a unitary transformation. A recent extension of the method to deformed nuclei provides the best description of the data, suggesting the significance of Landau damping.</P>

A linear polarization measurement for gamma rays has been performed to directly determine the parities for the levels in 155Gd. High-spin states in 155Gd were populated in the 154Sm(,3n )155Gd reaction by using 35-MeV alphas. Linearly polarized gamma rays emitted from oriented states were measured by using a Compton polarimeter which is made of a planar-type germanium crystal and is segmented into 25 cathodes. The linear polarization of the gamma rays was measured by selecting Compton-scattered events red in coincidence between two adjacent cathodes. The sign of the measured linear polarization enabled us to distinguish between electric and magnetic types of gamma-ray transitions. Accordingly, the parities of the high-spin states in 155Gd were directly determined. Our parity assignment is in excellent agreement with a previous one.
