The center-of-mass system for many bodies in R admits a natural action of the rotation group SO(3). According to the orbit types for the SO(3) action, the center-of-mass system M is stratified into strata. A quantum Hamiltonian system and a classical Lagrangian system are defined on L(M) and on T (M), respectively. These systems are also stratified according to the stratification of M , and the...

In this study, polysaccharides were isolated from Ganoderma lucidum (Polyporaceae) and their antitumor and anti-inflammatory activities were investigated using in vivo models. Potential antitumor activity was shown by G. lucidum polysaccharides (GLP) against solid tumor induced by Ehrlich's ascites carcinoma cells. GLP at 100 mg kg(-1) body mass showed 80.8 and 77.6% reduction in tumour volume ...

Parental body mass changes during the nesting period were analysed for Thekla Larks, Galerida theklae, and Lesser Short-toed Larks, Calandrella rufescens. Body mass of female Thekla Larks declines from the start of incubation until the chicks fledge; laying date, interpreted as the number of renesting attempts, also has a negative effect. Body mass of female Lesser Short-toed Larks was not rela...
