Abstract: Epitermálne vysokosulfidické (HS) zrudnenie viazané na vrchnoeocénske andezity oblasti Lahóca, je súèas ou rudného komplexu pohoria Matra v Ma arsku, pri dedinke Recsk. Tento komplex je charakterizovany skarnovym, Cu-porfyrovym a epitermálnym HS zrudnením. Cu-Au lo isko HS epitermálneho zrudnenia pri Lahóci a ili viac ako 130 rokov, predov etkym pre získanie medi. V HS lo isku má vyskyt zlata vysokú jemnos , tvorí zrnká ve kosti 1-30 mikrónov a nepravidelné pl ky. Zlato sa via e najm na pyrit. V prekremenelom matrixe sa zlato objavuje aj samostatne. V pyrite sa nevyskytuje v inklúziách, je v dy narastany na povrch pyritovych kry tálov.

Abstract: Aim To assess and compare the secular trend in age at menarche in Dutch girls (1955–2009) and girls from Turkish and Moroccan descent living in the Netherlands (1997–2009). Methods Data on growth and maturation were collected in 20,867 children of Dutch, Turkish and Moroccan descent in 2009 by trained health care professionals. Girls, 9 years and older, of Dutch (n = 2138), Turkish (n = 282), and Moroccan (n = 295) descent were asked whether they had experienced their first period. We compared median menarcheal age in 2009 with data from the previous Dutch Nationwide Growth Studies in 1955, 1965, 1980 and 1997. Age specific body mass index (BMI) z-scores were calculated to assess differences in BMI between pre- and postmenarcheal girls in different age groups. Results Median age at menarche in Dutch girls, decreased significantly from 13.66 years in 1955 to 13.15 years in 1997 and 13.05 years in 2009. Compared to Dutch girls there is a larger decrease in median age of menarche in girls of Turkish and Moroccan descent between 1997 and 2009. In Turkish girls age at menarche decreased from 12.80 to 12.50 years and in Moroccan girls from 12.90 to 12.60 years. Thirty-three percent of Turkish girls younger than 12 years start menstruating in primary school. BMI-SDS is significantly higher in postmenarcheal girls than in premenarcheal girls irrespective of age. Conclusion There is a continuing secular trend in earlier age at menarche in Dutch girls. An even faster decrease in age at menarche is observed in girls of Turkish and Moroccan descent in the Netherlands.

Abstract: China’s civil aviation industry experienced an average annual growth rate of over 16% for traffic turnover during 1955-2011. It is important to identify the role of capital and labor inputs as well as total factor productivity (TFP) in China’s civil aviation industry during this period of time. First, the inputs of capital stock and labor as well as the output of traffic turnover in China’s air transport industry are measured. Next, the constrained E-G two-stage estimation of the CD production function is used to calculate the capital and labor elasticities and TFP, which provides the necessary basis for the estimation of the growth sources in China’s air transport industry from 1955 to 2011. The results show that the growth of China’s civil aviation industry has depended on the capital factor input and that TFP has played an increasingly important role. Furthermore, the results also indicate that private sources have been crucial for improving the TFP after the 2002 reform.
