The new spacetime-supersymmetric description of the superstring is used to compute tree-level scattering amplitudes for an arbitrary number of massless four-dimensional states. The resulting Koba-Nielsen formula is manifestly SO(3,1) super-Poincaré invariant and is easily generalized to scattering in the presence of a D-brane.

Morphological delimitation of Asian black truffles, including Tuber himalayense, T. indicum, T. sinense, T. pseudohimalayense, T. formosanum and T. pseudoexcavatum, has remained problematic and even phylogenetic analyses have been controversial. In this study, we combined five years of field investigation in China with morphological study and DNA sequences analyses (ITS, LSU and β-tubulin) of 1...

In the present study, an attempt was made to investigate the anti-bacterial activity of Nyctanthes arbortristis, Nerium oleander and Catharathus roseus. The crude drug powder extracts of the leaves of the above plants were taken for the study. The antibacterial activity was performed by using both gram positive and gram gative organism viz., B.subtilis and E.coli respectively. The Phytochemical...

BACKGROUND 4-nitroquinoline 1-oxide (4-NQO) is a mutagen known to be responsible for causing cancer by generating oxidative stress in humans. Oroxylum indicum (L.) possesses various bioactive compounds with antioxidant properties. In this connection, the present study aims to analyze the alleviation of 4-NQO induced oxidative stress in albino Wistar rats using O. indicum (L.) leaf extract. ME...

The ascomata and mycorrhizae of Tuber indicum s.l. were collected under the forest of broad-leaf species Populus yunnanensis and Quercus pannosa in the field respectively. The symbiotic relationships of both trees with T. indicum were examined and affirmed based on morphology and ITS-rDNA sequences. These two mycorrhizal combinations were successfully produced on artificially controlled substra...

Although adaptive control (AC) systems for machine tools have a tremendous potential for improving productivity in manufacturing, their acceptance by industry has been slow. This paper identifies the major research and development areas for AC machine tools, and summarizes the principal developments of the last two decades. Current research at The University of Michigan, which is aimed at the d...
