The“giant component” has remained a guiding theme in the theory of random graphs ever since the seminal paper of Erdős and Rényi [Magayar Tud. Akad. Mat. Kutato Int. Kozl. 5 (1960) 17–61]. Because for any k ≥ 3 the k-core, defined as the (unique) maximal subgraph of minimum degree k, is identical to the largest kconnected subgraph of the random graph w.h.p., the k-core is perhaps the most natur...

BACKGROUND Few data concerning the oxidative stress (OS) in plasma during the entire menstrual cycle of eumenorrheic women are available. METHODS OS was assessed in 20 healthy volunteers during the phase of the menstrual cycle by determining the plasmatic hydroperoxides levels (d-ROMs test). The assessment was performed every three days, starting from the first day (t1) up the end of the mens...

Health-improving running loads are an effective means of improving the functions cardiovascular system. The study adaptive reactions system in women different somatotypes under influence health- classes allows to reveal dynamics main indicators that determine physical health a person and establish their somatotypological features. 80 first period mature age (25-35 years old), who had not played...

Let $pounds$ be the category of locally compact abelian groups and $A,Cin pounds$. In this paper, we define component extensions of $A$ by $C$ and show that the set of all component extensions of $A$ by $C$ forms a subgroup of $Ext(C,A)$ whenever $A$ is a connected group. We establish conditions under which the component extensions split and determine LCA groups which are component projective. ...

BACKGROUND According to statistics of American Society of Plastic Surgeons, cosmetic rhinoplasty was the second most frequently performed cosmetic surgery. This study shares the experiences with component rhinoplasty. METHODS From 2004 to 2010, all patients underwent aesthetic nasal surgery were enrolled. The patients requiring only correction of septal deviation and those presenting with cl...

The nucleotide sequences were determined for the 5'-oligonucleotides obtained by complete pancreatic RNase digestion (P25) and complete T1 RNase digestion (T27) of U-2 RNA. Complete digestion of oligonucleotide P25 with snake venom phosphodiesterase produced pm3 2,2,7G, pAm, pUm, and pCp in approximately equimolar ratios. Partial digestion of these oligonucleotides with snake venom phosphodiest...
