来自北欧的歌手,音乐似乎都带着冷冽。泡在八月天的热气里,当你摇晃在人山人海的地铁上,拿出手机点开一首恩雅或西丝儿·科尔克杰博(Sissel Kyrkjebo)的歌,一阵清凉的风便会吹进心间。但挪威女歌手欧若拉·艾克尼斯(Aurora Aksn... 来自北欧的歌手,音乐似乎都带着冷冽。泡在八月天的热气里,当你摇晃在人山人海的地铁上,拿出手机点开一首恩雅或西丝儿·科尔克杰博(Sissel Kyrkjebo)的歌,一阵清凉的风便会吹进心间。但挪威女歌手欧若拉·艾克尼斯(Aurora Aksnes)的音乐却不是风。它是极光,艳丽的色彩在黝黑的夜空不断变化着形态,于空旷、宁静中暗含着一股躁动不安的青春能量。这位二十六岁的女孩因翻唱绿洲乐队(Oasis)的《在世界的另一端》(Half the World Away)而广为人知。 展开更多

Based on inverse heat conduction theory, a theoretical model using 6-point Crank-Nicolson finite difference scheme was used to calculate the thermal conductivity from temperature distribution, which can be measured experimentally. The method is a direct approach of second-order and the key advantage of the present method is that it is not required a priori knowledge of the functional form of the unknown thermal conductivity in the calculation and the thermal parameters are estimated only according to the known temperature distribution. Two cases were numerically calculated and the influence of experimental deviation on the precision of this method was discussed. The comparison of numerical and analytical results showed good agreement. 展开更多

The possibility of describing the time-dependent processes of scattering by underlying surfaces and the clear sky, as well as the seasonal behaviour of the refractive index of troposphere by using nested semi-Markov processes has been consid- ered. Local Gaussian models can be used to describe the process inside each phase state. The possibility of describing the sta- tistics of reflections from the sea and the refractive index by using Kravchenko finite functions has been shown for the first time. 展开更多

Aiming to optimize the beer production process by improving the properties of beer and reducing production costs at the J.S.C. "Birra Peja" brewery, Peja, Kosovo, this study did an evaluation of beer produced using six different malts. Four of the six studied malts were produced in four European countries: Ukraine, Croatia, Serbia and Kosovo; and, the other two malts were obtained from two (2) 30:70 proportion mixtures: one from Kosovo and Ukraine and another one from Kosovo and Croatia. Chemical, microbiological, sensory and tasting analyses were carried on beers produced by these malts. The study included three working groups from: "Birra Peja"; the Agricultural University of Tirana, Albania and "Union Brewery", Ljubljana, Slovenia. Chemical and microbiological tests were based on methods under the EBC (European Beer Convention) and MEBAK (Mitteleurop^iische Brautechnische Analysenkommision e.V.) guidelines. The analyses and assessments made for the quality of beer have come to the conclusion that beer produced by Croatian origin malt corresponds to a better quality beer. 展开更多
