The complete mitochondrial genome (mitogenome) of Spilarctia robusta (Lepidoptera: Noctuoidea: Erebidae) was sequenced and analyzed. The circular mitogenome is made up of 15,447 base pairs (bp). It contains a set of 37 genes, with the gene complement and order similar to that of other lepidopterans. The 12 protein coding genes (PCGs) have a typical mitochondrial start codon (ATN codons), whereas cytochrome c oxidase subunit 1 (cox1) gene utilizes unusually the CAG codon as documented for other lepidopteran mitogenomes. Four of the 13 PCGs have incomplete termination codons, the cox1, nad4 and nad6 with a single T, but cox2 has TA. It comprises six major intergenic spacers, with the exception of the A+T-rich region, spanning at least 10 bp in the mitogenome. The nucleotide composition of the genome is greatly A+T biased (81.09%), with a negative AT skewness (-0.007), indicating the presence of fewer As than Ts, similar to other Noctuoidea. The A+T-rich region is 343 bp long, and contains some conserved regions, including an "ATAGA" motif followed by a 19 bp poly-T stretch, a microsatellite-like (AT)9 and a poly-A element, a characteristic shared with other lepidopteran mitogenomes. Phylogenetic analysis, based on 13 PCGs using Maximum likelihood methods revealed that S. robusta belongs to the superfamily Noctuoidea., Yu Sun, Sen Tian, Cen Qian, Yu-Xuan Sun, Muhammad N.

Let $G$ be a finite group. Let $X_1(G)$ be the first column of the ordinary character table of $G$. We will show that if $X_1(G)=X_1({\rm PGU}_3(q^2))$, then $G \cong{\rm PGU}_3(q^2)$. As a consequence, we show that the projective general unitary groups ${\rm PGU}_3(q^2)$ are uniquely determined by the structure of their complex group algebras., Farrokh Shirjian, Ali Iranmanesh., and Obsahuje bibliografické odkazy
The aim of this paper is to analyze changes in fertility in Slovakia in interwar period and to describe its overall character in transversal and longitudinal perspective. The article is based on data from vital statistics of Statistical office. Special attention is paid to the level of concious fertility control and spatial differencies. and Branislav Šprocha, Pavol Tišliar.
This article examines the development of panel studies and their main characteristics. The first part of this article outlines the historical development of panel studies. Here special reference is made to the first panel studies ever undertaken, and the influence of Paul Lazarsfeld on this field of research. Thereafter, there is an overview of some recent national panel studies, and different approaches used in the analysis of panel data. The second part of this article concentrates on the panel study as a type of longitudinal research where special attention is given to a number of issues: unit of analysis, mode of data collection, time span between waves of data collection, duration of panel studies, research themes and policy influences, and opportunities for studying change at the individual (micro) level. In the final section, there is a discussion of the specific difficulties associated with panel study research., Zdeňka Lechnerová., and Obsahuje bibliografii a bibliografické odkazy
Prezentovaný príspevok uvádza hlavné charakteristiky fluorescenčného farbiva merocyanínu 540 (MC 540), jeho interakciu s biologickými membránami a prehĺad jeho biofyzikálnych a biomedicínskych aplikácií.
