Function of a low molecular peptide generated by cellulolytic fungi for the degradation of native cellulose
Peptides (MW < 5 kDa) produced by 57 cellulolytic fungi can form free radicals. Scanning tunneling microscopy (STM) and IR spectroscopy showed that the peptide produced by Trichoderma pseudokoningii can break the...

The contractible subgraph of 5-connected graphs
An edge e of a k-connected graph G is said to be k-removable if G — e is still k-connected. A subgraph H of a k-connected graph is said to be k-contractible if its contraction results still in a k-connected graph...

A Note on Edge-Disjoint Hamilton Cycles in Line Graphs
It is well known that if a graph G contains a spanning closed trail, then its line graph L(G) is Hamiltonian. In this note, it is proved that if a graph G with minimum degree at least 4k has k edge-disjoint spann...

On Cyclic Edge-Connectivity and Super-Cyclic Edge-Connectivity of Double-Orbit Graphs
A cyclic edge-cut of a graph G is an edge set, the removal of which separates two cycles. If G has a cyclic edge-cut, then it is said to be cyclically separable. For a cyclically separable graph G, the cyclic edg...
