In this research, an ancient Iranian ceramic technology, which was published previously for the first time, has been used to produce various colored ceramic glazes.  The color of such ancient glazes was always blue and the suitable body for that is unique due to high quartz content. There is no report of other color productions in productive workshop and scientific publications. The basic purp...

light, amber and dark colored kernels were rated by eye on a scale of 3 different genotypes (zh1, zh2 and zh3). the oil content was measured using the soxhlet extraction method, ranged from 57.26 to 68.29%, for zh1 (light) and zh2 (amber) respectively. fatty acid compositions were measured using gas chromatography. the main fatty acids were linoleic, oleic and linolenic acids, respectively. als...

A territorial isolation is a danger to the game population, causing deterioration called the inbreeding depression. The typical signs are anomalous body proportions, such as short lower jaw, shortened lifetime, weak physique and lower birth rate. This is caused by low number of game in the community. White colored deer is in the location of the CzechRepublicbred in separation since 18th century...

Let G be a planar graph with n vertices whose vertex set is partitioned into subsets V0, . . . , Vk−1 for a positive integer 1 ≤ k ≤ n and let S be a set of n distinct points in the plane partitioned into subsets S0, . . . , Sk−1 with |Vi| = |Si| (0 ≤ i ≤ k − 1). This paper studies the problem of computing a crossing-free drawing of G such that each vertex of Vi is mapped to a distinct point of...

The homomorphisms of oriented or undirected graphs, the oriented chromatic number, the relationship between acyclic coloring number and oriented chromatic number, have been recently studied. Improving and combining earlier techniques of N. Alon and T. H. Marshall (1998, J. Algebraic Combin. 8, 5 13) and A. Raspaud and E. Sopena (1994, Inform. Process. Lett. 51, 171 174) we prove here a general ...
