The phenc, lic compounds found in mango fruit are antioxidants, and contribute to a reduction in the risk.of cardiovascular diseases. Mango carotenoids are synthesized in mango fruit during ripening. A major by-product of mango fruit is the sk.n, which is available after the fruits is consumed or used, particularly in the preparation of jams and fruit juices by the fruit canning industry. The objective of this study was to investigate the effects of dietary mango sk.n （MS） or mango sk.n combined with paprik. extracts （PE） on production performance, egg quality, and egg yolk.polyphenols. Total of 60 44-week.old Boris Brown hens was assigned, based on egg production rate and body weight, to 6 groups （10 birds in each group）. The laying hens were fed a basal diet （control group, 18 CP, 2,800 k.al/k. ME）, a basal diet supplemented with 0.1% PE, 1% or 5% MS, or with a mixture of 0.1% PE with 1% or 5% MS respectively. During the three-week.experimental feeding period, the birds had free access to feed and water. Feed consumption was measured week.y and egg production was recorded daily. The results for initial body weight, feed consumption, hen-day production, egg mass, mortality, and final body weight did not indicate any effects of the different treatments （P 〉 0.05）. There were no significant differences （P 〉 0.05） in shell-break.ng strength, shell thick.ess, shell ratio, yolk.ratio or Haugh units, except in the case of egg yolk.color. Roche yolk.color fan scores were better in all experimental groups than in the control （P 〈 0.0001）. The yolk.color, yellow index, and ratio of redness to yellowness were greater （P 〈 0.0001） in the 0.1% PE, the 0.1% PE ＋ 1% MS, and the 0.1% PE ＋ 5% MS group than in the 1%, 5% MS, and control groups. Compared with the control, lightness was decreased significantly in the 0.1% PE, the 0.1% PE ＋ 1% MS, and the 0.1% PE ＋ 5% MS groups （P 〈 0.05）, whereas redness was increased significantly in the 0.1% PE, 0.1% PE ＋ 1% MS, and 0.1% PE ＋ 5% MS

Large grain niobium has the potential of simplifying the production sequence and consequently reducing the cost of the superconducting RF cavities for ILC. To investigate the feasibility of fabrication and the possibility to achieve high gradient by large grain cavities, two 1.3 GHz cavities were made of China large grain niobium and a series of vertical tests were carried out following several different surfaces treatment procedures. Two cavities have both reached the high gradient of more than 43 MV/m repeatedly and the maximum accelerating field of 47.9 MV/m has been achieved by China large grain niobium. This paper introduces the features of the fabrication and surface treatments on the large grain cavities and presents the preliminary results of the research.

ZnTe is a promising material for pure green light emitting diodes （LEDs）. Since the LED is obtainable by a thermal diffusion of Al into phosphorus （P）-doped ZnTe, P is considered to be a suitable p-type dopant in ZnTe. In previous studies, we have successfully grown P-doped ZnTe films by metalorganic vapor phase epitaxy （MOVPE） using tris-dimethylaminophosphorus （TDMAP） as a P source. In order to obtain P-doped ZnTe film with a high carrier concentration of around 1018 cm-3, however, nitrogen annealing treatment is required after the growth for a relatively lower substrate temperature such as 420 oC. On the other hand, a use of a substrate temperature of 500 oC leads to P-doped ZnTe film with a carrier concentration as high as 1.3×1018 cm-3 without the annealing treatment, indicating that a high substrate temperature is favorable for obtaining high concentration easily. Therefore, it is important to investigate the role of the ratio of the transport rate of diethyltelluride to dimethylzinc, so-called VI/II ratio, in photoluminescence （PL） and electrical properties in P-doped ZnTe grown at 500 oC to acquire the k.owledge concerning doping mechanism of ZnTe, since such investigations do not exist. The P-doped films were grown by atmospheric pressure MOVPE in almost the same manner as was employed in the previous studies. In this experiment, hydrogen carrier gas flow rate was 4.8 slm. DETe and TDMAP transport rates were k.pt at 84 and 3μmol/min, respectively. The low temperature PL spectrum of P-doped film varies with the VI/II ratio considerably. For the VI/II ratios less than 1.2, i.e., under a Te rich condition, PL spectrum is dominated by a weak.donor-related bound exciton peak.at 2.378eV and a strong acceptor-related bound exciton one at 2.375 eV together with a considerably weak.free exciton one at 2.38 eV, indicating the difficulty of P doping. For a VI/II ratio of one, on the other hand, the PL spectrum is characterized by strong acceptor-related exciton and fr

A long-pulse plasma discharge for more than 30 min. was achieved on the Large Helical Device （LHD）. A plasma of ne = 0.8 × 10^19 m^-3 and T10 = 2.0 k.V was sustained with PICH = 0.52 MW, PECH = 0.1 MW and averaged PNBI = 0.067 MW. Total injected heating energy was 1.3 G J, which was a quarter of the prepared RF heating energy. One of the k.ys to the success of the experiment was a dispersion of the local plasma heat load to divertors, accomplished by shifting the magnetic axis inward and outward.

Zn1-xMgxTe ternary alloy is a candidate for an optically active layer in green-to-blue range of spectrum and a cladding layer for improving a performance of ZnTe-based pure-green light-emitting-diodes and for realizing ZnTe-based laser diodes. Unfortunately, there are only a few work. on Zn1-xMgxTe epitaxial layer grown by metalorganic vapor phase epitaxy （MOVPE）, which is a potential epitaxial growth technique for mass production. In our previous studies, nominally undoped Zn1-xMgxTe epitaxial layers have been successfully grown on （100） ZnTe substrates by MOVPE using dimethylzinc （DMZn）, bis-methylcyclopentadienyl-magnesium （（MeCp）2Mg） and diethyltelluride （DETe）. It has been found that the Mg composition in the layer drastically increases with decreasing DETe transport rate or with increasing the total carrier gas flow rate. In addition, we have reported on the relationship between the optical quality of the grown layers and the transport rate ratio of group VI source to group II ones. On the other hand, the substrate temperature is also one of the important parameter of growth condition. However, there is no report on the influence on the growth of Zn1-xMgxTe layer. In this work. we studied the effects of substrate temperature upon the optical properties, Mg composition, and surface morphology of undoped Zn1-xMgxTe layers grown by MOVPE. The growth of undoped Zn1-xMgxTe layers was performed on （100） ZnTe substrates using a vertical-type atmospheric pressure MOVPE system in almost the same manner as employed in the previous studies. The transport rates of DMZn, （MeCp）2Mg, and DETe were fixed at 15, 2, and 10μmol/min, respectively. The total flow rate of hydrogen carrier gas was 800 sccm. The substrate temperature （Tsub） was varied from 340 to 420 °C. The Mg composition （x） and the surface morphology were investigated by energy dispersion X-ray （EDX） analysis and atomic force microscopy, respectively. Photoluminescence （PL） measurement was performed at 4.2 k. The

The effect of ionospheric delay on the ground-based augmentation system under normal conditions can be mitigated by determining the value of the nominal ionospheric gradient(σvig).The nominal ionospheric gradient is generally obtained from Continuously Operating Reference Stations data by using the spatial single-difference method(mixed-pair,station-pair,or satellite-pair)or the temporal single-difference method(time-step).The time-step method uses only a single receiver,but it still contains ionospheric temporal *** introduce a corrected time-step method using a fixed-ionospheric pierce point from the geostationary equatorial orbit satellite and test it through simulations based on the global ionospheric *** also investigate the effect of satellite paths on the corrected time-step method in the region of the equator,which tends to be in a more north–south direction and to have less coverage for the east–west ionospheric *** study also addresses the limitations of temporal variation correction coverage and recommends using only the correction from *** processes are developed under simulations because observational data are still difficult to *** findings demonstrate that the corrected time-step method yieldsσvig values consistent with other approaches.
