The photosynthetic CO2-fixing enzyme, ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), is renowned for its slow catalytic rate and difficulty in distinguishing between the substrate of photosynthesis, CO2, and one of the products, O2. The oxygenase activity was discovered 45 years ago (Bowes et al., 1971), nearly 20 years after the discovery of the carboxylase activity (Quayle et al.,...

The forest tent caterpillar is polymorphic far two melanic genes affecting wing color of moths. These are the first genetically determined morphological traits reported for the genus. Dark (D) is a sex-limited, autosomal dominant with a phenotype of dark brown males. Frequencies in population samples varied from 8 to 44%. Characteristics of Dark and nonmelanic males were compared. Larval develo...

Analytical transmission electron microscopy (ATEM) is a powerful tool to obtain the chemical compositions of minerals at very small areas down nanometer scale. Most ATEM analytical systems are capable performing quantitative calculations by absorption correction. However, an appropriate procedure obtaining correct correction has not yet been established. In this study, we analyzed thin foils ga...

Three scattering mechanisms that limit the observable properties low-frequency emission from transient sources are discussed. Both Induced Compton and Induced Raman scattering hinder the escape of the bright radiation envisaged to be generated from the compact extragalactic transients and that many hope to detect with future widefield radio telescopes. In cases where the radiation is observed, ...
