Ebben a tanulmányban megvizsgáljuk azt nyelvezetet, amelyet Ptolemaiosz használt katalógusában csillagok leírására. A katalógust eddig behatóan vizsgálták benne található adatok tekintetében, ám szöveges leírásokra nem sok koncentrált figyelem irányult. Mi az ún. anatómiai leírásokat vesszük szemügyre (több mint 700 darab): ezek olyan szövegrészletek, melyek azáltal azonosítják tárgyukat, azaz ...

introduction considering the nutrient loss, environmental pollution and increase in production costs on account of chemical fertilizer application, supplying mineral nutrients based on organic sources and mycorrhizal inoculation can improve organic matter content in soil (khandan & astaraei, 2005; halajnia et al., 2007), promote sustainable production of oil crops (mostafavian et al., 2008; kaw...

the aim of this study was to investigate the effect of tillage methods to obtain suitable seedbed for monogerm seed. therefore, a split plot experiment based on a randomized complete block design (rcbd) with three replicatians was conducted at darab station of fars province. the main plot was seedbed prepration at two levels including fall and spring season. subplot included 1) moldboard plow a...

the stability of ten winter safflower cultivars and lines was evaluated in three different environmental conditions in karaj, isfahan and darab in iran, a randomized complete block design with 4 replications over three years (1995, 1996 and 1997). simple analysis of variances of grain and oil yields from each experiment showed significant differences among the genotypes. after conducting a homo...

Hydrogen is a clean and environmentally friendly energy vector that can play an important role in meeting the world’s future needs. Therefore, comprehensive study of potential for hydrogen production from solar could greatly facilitate transition to economy. Because by knowing exact amount production, cost-effectiveness its be compared with other methods production. Considering above, it seen s...

Abstract Background Barley is one of the most important cereal crops with considerable tolerance to various environmental stresses, which can maintain its productivity well in marginal croplands. The selection stable and high-yielding barley genotypes ideal discriminative locations an strategy for development new cultivars tropical climates. Different statistical methods have been developed dis...
