In this note we investigate some matroid minor structure results. In particular, we present sufficient conditions, in terms of triangles, for a matroid to have either U2,4 or F7 or M(K5) as a minor.

the subcutaneous inoculation of 16 white mice and 10 golden hamsters with l.tropica major resulted in the development of leishmanial lesions in all, becoming generalized in some.two of 10 hamsters inoculated intraperitoneally with this parasite developed generalized lesions. on the other hand, the inoculation of l. tropica minor to 128 mice subcutaneously and 170 mice intraperitoneally did not ...

conclusions penetrating trauma from wooden fragments provides a diagnostic challenge. a stubborn discharge from a wound must always raise the suspicion of retained fragment. early and appropriate surgical exploration is imperative. introduction in contrast with victims of major trauma, patients who suffer minor injuries receive little specialist input. in most cases, this causes no difficulty, ...

introduction and objective: zinc as the second trace element of the human body plays an important role in numerous functions. a large number of research studies have showed serum zinc deficiency and excess urinary excretion in patients with major beta thalassemia, but few studies revealed excess urinary zinc excretion in minor beta thalassemia and no study investigated serum zinc levels in this...

A minor-closed class of graphs is a set of labelled graphs which is closed under isomorphism and under taking minors. For a minor-closed class G, we let gn be the number of graphs in G which have n vertices. A recent result of Norine et al. [12] shows that for all minor-closed class G, there is a constant c such that gn ≤ c nn!. Our main results show that the growth rate of gn is far from arbit...

salivary  gland  tumors  accounts  for  less  than  1%  of  all  tumors.  minor  salivary  gland  tumors (msgts) are uncommon and make up about 10% of all salivary gland neoplasms. the clinical and histopathological distribution of these tumors vary geographically. a case of a 38 yr old man with a minor salivary gland mass at chin region isreported here. the tumor invaded into the anterior surf...
