Introduction. Previous track-thermoluminescence (TL) investigations [1, 2] of the lunar regolith silicate crystals demonstrate the possibility of measuring of the effects from the local shock-thermal events initiated chiefly by micrometeorite
One of the pre-treatment processes on silk is degumming that has much influences on other processing. There are various degumming methods and each one has its own advantages and disadvantages. In this research protease (Alkalase) and Keliab (remaining ashes of "Oshnow" plant obtained from Qom, Yazd and Kashan) used as environmentally friendly compounds for degumming of silk. Different...

It is argued that racism systemic in its historical roots, anchored racialising discourses, bolstered and fused by ideology of Whiteness. describes an approach organisational consultancy, where consultant can facilitate change adopting anti-racism stance which disrupts Whiteness engages organisation praxis...
We discuss the composition and size distribution of the dust in the coma of comet Hale-Bopp. We do this using a model fit for the infrared emission measured by the infrared space observatory (ISO) and the measured degree of linear polarization of scattered light at various phase angles and wavelengths. The effects of particle shape on the modeled optical properties of the dust grains are taken ...
the study of nucleation mechanism of new grains during severe plastic deformation of magnesium alloys is of great importance to control the characteristics of final microstructures. to investigate the role of discontinuous recrystallization, a wrought az31 magnesium alloy was deformed by accumulative back extrusion process at 330 °c. the obtained microstructures were studied using optical and...
Abstract This article examines how racial capitalism has shaped the ecological and technological dynamics of cotton production in United States South. Cotton’s destructive dependence on chemicals extraction lives resources was animated enabled by anti-Blackness, which sanctioned a systematic hostility to life that encoded environmental violence plantation landscapes from seed root.
