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

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
