The detectability of planetesimal impacts on imaged exoplanets can be measured using Jupiter during the 1994 comet Shoemaker-Levy 9 events as a proxy. By integrating the whole planet flux with and without impact spots, the effect of the impacts at wavelengths from 2 4 μm is revealed. Jupiter’s reflected light spectrum in the near-infrared is dominated by its methane opacity including a deep ban...

In developing countries pulmonary tuberculosis is usually diagnosed by detecting acid-fast bacilli (AFB) in sputum using a Ziehl-Neelsen (Z-N) staining method. However, in the field the traditional method of staining is difficult to carry out. This study evaluates the efficiency of two cold staining methods, namely Gabbet’s and a modified two reagent cold staining method compared with the Z-N t...

Based on the work in (Poller, 1994) and a minor assumption about a normal form for TAGs, we present a highly simplified version of the twostep parsing approach for TAGs which allows for a much easier analysis of run-time and space complexity. It also snggests how restrictions on the grammars might result in improvements in run-time complexity. The main advantage of a two-step parsing system sho...
