BACKGROUND AND AIMS Dryopteris crassirhizoma is a semi-evergreen fern growing on the floor of deciduous forests. The present study aimed to clarify the photosynthetic and storage functions of overwintering leaves in this species. METHODS A 2-year experiment with defoliation and shading of overwintering leaves was conducted. Photosynthetic light response was measured in early spring (for overw...

By A. Jefferis Turner, m.d. (Intercolonial Medical Journal of Australasia.)?After describing the spread of anchylostomiasis in Australia, Dr. Turner gives his experience of treatment. He had disappointing results with calomel, santonin, male fern, naphthalin, naphthol, thymol, and other drugs. Ordinary doses of thymol, such as five grains thrice daily, he had found utterly useless; but on readi...

Recall that many combinatorial problems of interest can be encoded as integer linear programs. Solving integer linear programs is in general NP-hard, so we nearly always relax the integrality requirement into a linear constraint like nonnegativity during our analysis. Our previous algorithms for solving these problems never solved the relaxed program explicitly (e.g. using simplex). In LP round...

We have analyzed how much the CP angles to be measured at B factories can deviate from the geometrical ones de ned in unitarity triangle under the existence of new physics. The measurements are given in rephasing invariant form. If KM matrix is not a 3 3 and unitary matrix, ~ 1 and ~ 3 is a ected, and the value of ~ 3 depends on the decay mode. The deviation is constrained to be less than the e...

Polystichum Roth is one of the largest and most taxonomically challenging fern genera. South American species have a rich and complex nomenclatural history; many of the early names are inadequately typified. Based on extensive examination of original type material, we designate eleven lectotypes (including Aspidium mohrioides, Aspidium montevidense f. imbricata, Aspidium montevidense f. squamul...
