Variation of the Diameter of the Sun as Measured by the Solar Disk Sextant (SDS)

The balloon-borne Solar Disk Sextant (SDS) experiment has measured the angular size of the Sun on seven occasions spanning the years 1992 to 2011. The solar half-diameter -- observed in a 100-nm wide passband centred at 615 nm -- is found to vary over that period by up to 200 mas, while the typical estimated uncertainty of each measure is 20 mas. The diameter variation is not in phase with the solar activity cycle; thus, the measured diameter variation cannot be explained as an observational artefact of surface activity. Other possible instrument-related explanations for the observed variation are considered but found unlikely, leading us to conclude that the variation is real. The SDS is described here in detail, as is the complete analysis procedure necessary to calibrate the instrument and allow comparison of diameter measures across decades.Comment: 41 pages; appendix and 2 figures added plus some changes in text based on referee's comments; to appear in MNRA

Charcot-Marie-Tooth disease-associated mutants of GDAP1 dissociate its roles in peroxisomal and mitochondrial fission

Journal ArticleCopyright © 2013 European Molecular Biology OrganizationMitochondria and peroxisomes can be fragmented by the process of fission. The fission machineries of both organelles share a set of proteins. GDAP1 is a tail-anchored protein of mitochondria and induces mitochondrial fragmentation. Mutations in GDAP1 lead to Charcot-Marie-Tooth disease (CMT), an inherited peripheral neuropathy, and affect mitochondrial dynamics. Here, we show that GDAP1 is also targeted to peroxisomes mediated by the import receptor Pex19. Knockdown of GDAP1 leads to peroxisomal elongation that can be rescued by re-expressing GDAP1 and by missense mutated forms found in CMT patients. GDAP1-induced peroxisomal fission is dependent on the integrity of its hydrophobic domain 1, and on Drp1 and Mff, as is mitochondrial fission. Thus, GDAP1 regulates mitochondrial and peroxisomal fission by a similar mechanism. However, our results reveal also a more critical role of the amino-terminal GDAP1 domains, carrying most CMT-causing mutations, in the regulation of mitochondrial compared to peroxisomal fission. © 2013 European Molecular Biology Organization.Swiss National Science FoundationNational Center for Competence in Research (NCCR)BBSRCPortuguese Foundation for Science and Technology (FCT)Fundo Europeu De Desenvolvimento Regional (FEDER

Kebugaran dan Produktivitas Kerja Tenaga Kerja Wanita Selama Berpuasa Ramadhan

This study evaluated changes in nutrient intake of female labourers during Ramadhan fasting, in relation to the changes in iron status and blood glucose level which may affect fitness and productivity. A total of 40 female labourers were randomly chosen from 200 sample population, with the criteria: Hb value >12 g%, not lactating or pregnant, nor had metabolic disorders. They had to follow the research agenda and had to fast during the Ramadhan month, 1417 H, except when they were in menstruation period. Data on food intakes, blood component, fitness, and total patch clothes sown were collected a week before, the first and third week during Ramadhan, and a month after Lebaran. Hemoglobin and hematocrite as indicators of iron status were determined. Average energy intake before fasting month was 142% of the RDA, while during the fasting month it was 124%. Most of the labourers used to have breakfast daily, which has an averages of 30% of their total daily intake. During fasting they had 40% of total energy intake from early breakfast (makan sahur). There were decrease in energy and vegetable protein but increase in animal protein, vitamin C, and iron consumption. Glucose level and iron status were decreased but did not cause hypoglycemia nor anemia. Productivity and fitness improved during the fasting month. Total patches sown as productivity indicator were increased by 17% during morning, but decreased by 10% during afternoon sessions. Fitness improved by one level, from low to average. This study concluded that energy intakes of female labourers were lower, but fitness and productivity were better during the fasting month
