This study analysed the physiological, nutritional and performance profiles of athletes practicing Brazilian jiu-jitsu. To this end, 15 athletes that practiced Brazilian jiu-jitsu (aged: 28 ± 5 years; 8 brown belts and 7 black belts; training experience: 11 ± 4 years) underwent anthropometric measurements (body composition and somatotype), dietary evaluation (24 h recall) and physical fitness t...

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...

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. ...
