[en] In color superconductor the gluon condensate drops down at moderate density but goes up at high density and can even exceed its vacuum value when the density is high enough. (authors)

[en] A study was made on the variation in fruit red color in a population of 'Royal Gala' apple developed from buds irradiated with gamma rays. A wide range of coloration was observed between the clones, however except for one clone the range of variation within clones was small

[en] We review and extend recent findings of Godsil and Zaks, who published a constructive colouring of the rational unit sphere with the property that for any orthogonal tripod formed by rays extending from the origin of the points of the sphere, exactly one ray is red, one white and one black. They also showed that any consistent colouring of the real sphere requires an additional colour. We discuss some of the consequences for the Kochen-Specker theorem. (author)

[en] Scales of the longhorn beetle Sphingnotus mirabilis possess a disordered bicontinuous macroporous structure that resembles a structure formed by a phase-separation process of spinodal decomposition. By using the scales as templates, SiO_2 and TiO_2 structures were successfully replicated. Structural and optical characterizations show that the fabricated oxide structures are spinodal decomposition structures with only short-range order and display non-iridescent structural colors.

[en] The goal of ultrasound guided fine-needle aspiration (USFNA) is to obtain most cellular specimen that represents the nodule. However, there is substantial variability in specimen cellularity depending on the obtaining techniques. While performing USFNA, it is not clear whether the needle tip should be placed at hypovascular or hypervascular site of the nodule to obtain more cells for cytological analysis. The aim of the study was to assess whether USFNA of the hypovascular or hypervascular site of a thyroid nodule would reveal more cells for cytological analysis. Twenty-three consecutive patients with solid thyroid nodules larger than 2 cm were aspirated under color Doppler sonography guidance. First pass was from the hypovascular site and the second pass from the hypervascular site. The aspirates were scored from 1-3 by cytologist according to number of cell groups. When only hypervascular site was used, adequate sampling was limited to 65% of the cases. When both sites were evaluated together, overall adequate sampling was 91%. Adding a sample from the hypervascular site to hypovascular aspirate increased the adequate sampling by 8%. The highest pathological score was achieved when both hypo- and hypervascular site aspirates were evaluated together. The aspirates from the hypovascular and hypervascular sites of solid nodules are complementary and should be performed consecutively

[en] In Nuclear Malaysia, a study on gemstone irradiation using beta particle is conducted. The purpose of the study is to evaluate the gemstone colour enhancement by using different kind of precious and non-precious gemstones. By using irradiation technique, selected gemstones are exposed to highly ionizing radiation electron beam to knock off electrons to generate colour centres culminating in the introduction of deeper colours. The colour centres may be stable or unstable depending on the nature of colour centre produced. The colour change of irradiated stones were measured by HunterLab colour measurement. At 50 kGy, Topaz shows changes colour from colourless to golden. Meanwhile pearl shows changes from pale colour to grey. Kunzite and amethyst shows colour changes from colorless to green and pale colour to purple. Gamma survey meter measurement confirmed that irradiation treatment with 3 MeV electron beam machine does not render any activation that activate the gems to become radioactive

[en] The polyimide films are colored by radiation exposure. The color of irradiated films, however, fades with the exposure time in air. This discoloration obscures the accurate evaluation of degradation in ground-simulation tests. Therefore, we experimentally clarified the discoloration behaviors for the post-irradiation sample in air. There was a difference in the time constant of air recovery among the three types of polyimides. The recovery behavior depended on the type and thickness of the polyimide. In addition to these, it would be deduced that the behavior of color fading depends on the uniformity of degradation. If the coloration immediately after irradiation is needed to evaluate the degradation, it is necessary to know the recovery behavior on each type and thickness of polymer because the order of radiation resistance varies depending upon the length of time that has elapsed since the air exposure of irradiated sample
