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.

AEROSOL PARAMETER ESTIMATION FROM ADEOS/POLDER DATA
Yamazaki, A.,Kawata, Y. 대한원격탐사학회 1997 International Symposium on Remote Sensing Vol.13 No.1
In this paper we have made the aerosol optical parameter estimation using the reflectance and polarization data measured over Arabian Sea near Indian Continent by the ADEOS/ POLDER sensor[1]. Assuming an atmosphere-ocean system with a Cox-Munk type reflecting sea surface [2], the reflectance and polarization, including radiance contributions from multiple scatterings within the atmosphere and multiple reflections between the atmosphere and the sea surface, have been computed by using the adding and doubling method for several typical aerosol models, namely, Water Soluble, Oceanic and Junge Models. In this study we found only Junge type model with v=3.5 and refractive index m=1.50-i0.05 can satisfy the observed reflectance and polarization data in the principal plane.

Various characteristic features of elastic deformation of dies and presses during deep drawing were presented. It was very important to examine the effects of elastic deformation of these units on product accuracy. Strains were measured on the press system including dies, a slide and a bolster of a servo press. A strain magnitude of 63 ×10<SUP>-6</SUP> was obtained when the overall slide position was at the lowest point. Two slide motions of the servo press were selected to determine appropriate manufacturing conditions. An elastic deformation analysis of the die structure was then required by CAD simulation. To find the appropriate die structure model, the vertical displacement of the die structure in the CAD simulation only was compared to the experiment results. It was found that the vertical displacement of the die structure was 0.176 mm at the top surface of the die considering elastic deformation of the die structure as well as the bolster of the servo press.

Natto is a Japanese traditional soybean product fermented by Bacillus natto. The effect of natto supplement on the production and qualities of chicken meat was studied since the effective use of various waste foods is required in Japan. Dried natto prepared by heating at $60^{\circ}C$ was added to a basic diet at an amount of below 2%. The supplementation of dried natto did not influence the weights of the carcass, breast and thigh meat, fillet or abdominal fat. Growth of the thighbone such as the length, thickness of cortex bone, and Ca/P ratio in bone ash were not altered by the addition of natto. However, the pH of male meat decreased following the supplementation of dried natto from days 28 to 80. The water-soluble protein content in male thigh meat increased in the group fed 2% natto from days 28 to 80. Free peptides increased in male thigh meat by feeding 2% natto from days 0 to 80. The supplementation of natto increased free glutamic acid in thigh meat regardless of sex. Moreover, the supplementation of natto specifically decreased meat cholesterol in female chickens though the effect was not shown in male chickens.
Effect of Fermented Soybean "Natto" Supplement on Egg Production and Qualities
Fujiwara, K.,Miyaguchi, Y.,Toyoda, A.,Nakamura, Y.,Yamazaki, M.,Nakashima, K.,Abe, H. Asian Australasian Association of Animal Productio 2008 Animal Bioscience Vol.21 No.11
Natto is a Japanese traditional soybean product fermented by Bacillus natto. The effects of dried fermented soybean (natto) supplement on egg production and egg qualities of layer chickens was studied with regard to the effective use of various waste foods in Japan. Dried natto, prepared by heating at $60^{\circ}C$, was added to a basic diet at a level of up to 3%. Forty 166-wk-old layer chickens (Rhode Island Red) were randomly divided into 4 groups and five layer chickens were used in each group with two replicates. Layer chickens in group 1 were fed a basic diet as the control. The remaining 3 groups were fed the basic diet supplemented with dried natto at levels of 1, 2, and 3% (w/w), respectively. The result did not show improvements in egg production or feed conversion ratio of layer chickens even when 3% dried natto was added to the control diet. The egg qualities including egg weight, eggshell strength and thickness, yolk color, yolk weight, albumen height, and Haugh unit were also not improved. However, the feeding of dried natto changed the cholesterol content in the egg yolk. The supplementation of dried natto showed the tendency to decrease the yolk cholesterol after 12-wk of feeding compared to the control diet though it did not change plasma cholesterol levels in the blood. On the other hand, yolk cholesterol decreased significantly after 12-wk of feeding 3% dried natto (p<0.05).
Single-Electron Device With Si Nanodot Array and Multiple Input Gates
Kaizawa, T.,Arita, M.,Fujiwara, A.,Yamazaki, K.,Ono, Y.,Inokawa, H.,Takahashi, Y.,Jung-Bum Choi IEEE 2009 IEEE TRANSACTIONS ON NANOTECHNOLOGY Vol.8 No.4
<P>We have developed a flexible-logic-gate single-electron device (SED) with an array of nanodots. Although the small size of SEDs is highly advantageous, the size of the nanodots inevitably fluctuates, which causes variations in device characteristics. This variability can be eliminated and high device functionality can be obtained by exploiting the oscillatory characteristics and multigate capability of SEDs. We fabricated, on a silicon-on-insulator wafer, a Si nanodot array device with two input gates and a control gate and investigated its basic operation characteristics experimentally. The device was demonstrated to operate as a logic gate providing six important logic functions ( and, or, nand, nor, xor, and xnor), which are obtained by adjusting the control-gate voltage.</P>

<P><B>Combinations to regulate Cl<SUP>−</SUP> signaling</B></P><P>The secretion of HCO<SUB>3</SUB><SUP>−</SUP>-containing fluids is vital to the function of all epithelia and is enabled in part by the activity of the Na<SUP>+</SUP>-coupled HCO<SUB>3</SUB><SUP>−</SUP> transporter NBCe1-B. Vachel <I>et al</I>. identified five serine residues in NBCe1-B whose phosphorylation status was controlled by the regulatory protein IRBIT. The phosphorylation status of Ser<SUP>12</SUP> and Ser<SUP>65</SUP> affected the Cl<SUP>−</SUP> sensitivity of two intracellular Cl<SUP>−</SUP>-sensing motifs. Moreover, IRBIT recruited a distinct kinase/phosphatase pair for each serine residue. The three remaining phosphorylation sites were phosphorylated in distinct combinations that determined the relative basal activity level of NBCe1-B and the potential for further activation by IRBIT. These results demonstrate how distinct phosphorylation patterns may enable epithelial cells to fine-tune the HCO<SUB>3</SUB><SUP>−</SUP> transport activity of NBCe1-B in response to varying conditions in different parts of the organ.</P><P>IRBIT is a multifunctional protein that controls the activity of various epithelial ion transporters including NBCe1-B. Interaction with IRBIT increases NBCe1-B activity and exposes two cryptic Cl<SUP>−</SUP>-sensing GXXXP sites that enable regulation of NBCe1-B by intracellular Cl<SUP>−</SUP> (Cl<SUP>−</SUP><SUB>in</SUB>). Here, phosphoproteomic analysis revealed that IRBIT controlled five phosphorylation sites in NBCe1-B that determined both the active conformation of the transporter and its regulation by Cl<SUP>−</SUP><SUB>in</SUB>. Mutational analysis suggested that the phosphorylation status of Ser<SUP>232</SUP>, Ser<SUP>233</SUP>, and Ser<SUP>235</SUP> was regulated by IRBIT and determined whether NBCe1 transporters are in active or inactive conformations. The absence of phosphorylation at Ser<SUP>232</SUP>, Ser<SUP>233</SUP>, or Ser<SUP>235</SUP> produced NBCe1-B in the conformations pSer<SUP>233</SUP>/pSer<SUP>235</SUP>, pSer<SUP>232</SUP>/pSer<SUP>235</SUP>, or pSer<SUP>232</SUP>/pSer<SUP>233</SUP>, respectively. The activity of the pSer<SUP>233</SUP>/pSer<SUP>235</SUP> form was similar to that of IRBIT-activated NBCe1-B, but it was insensitive to inhibition by Cl<SUP>−</SUP><SUB>in</SUB>. The properties of the pSer<SUP>232</SUP>/pSer<SUP>235</SUP> form were similar to those of wild-type NBCe1-B, whereas the pSer<SUP>232</SUP>/pSer<SUP>233</SUP> form was partially active, further activated by IRBIT, but retained inhibition by Cl<SUP>−</SUP><SUB>in</SUB>. Furthermore, IRBIT recruited the phosphatase PP1 and the kinase SPAK to control phosphorylation of Ser<SUP>65</SUP>, which affected Cl<SUP>−</SUP><SUB>in</SUB> sensing by the <SUP>32</SUP>GXXXP<SUP>36</SUP> motif. IRBIT also recruited the phosphatase calcineurin and the kinase CaMKII to control phosphorylation of Ser<SUP>12</SUP>, which affected Cl<SUP>−</SUP><SUB>in</SUB> sensing by the <SUP>194</SUP>GXXXP<SUP>198</SUP> motif. Ser<SUP>232</SUP>, Ser<SUP>233</SUP>, and Ser<SUP>235</SUP> are conserved in all NBCe1 variants and affect their activity. These findings reveal how multiple kinase and phosphatase pathways use phosphorylation sites to fine-tune a transporter, which have important implications for epithelial fluid and HCO<SUB>3</SUB><SUP>−</SUP> secretion.</P>
