Interstellar dust grains exhibit complex dynamics which is essential for understanding many key interstellar processes that involve dust, including grain alignment, grain growth, grain shattering etc. Grain rotational and translational motions are affected not only by gaseous collisions, but also by interactions with ions, photons, magnetic fields etc. Some of those interactions, e.g. interacti...

We discuss the dynamics of dust grains subjected to uncompensated torques arising from H 2 formation. In particular, we discuss grain dynamics when a grain spins down and goes through a " crossover ". As first pointed out by Spitzer & McGlynn (1979), the grain angular momentum before and after a crossover event are correlated, and the degree of this correlation affects the alignment of dust gra...

background and objectives: evaluation of the grain yield and yield components and also morphological traits can help to identify strategies for selection of resistant cultivars and increased crop yield production under heat stress condition. to this end, in experiment to evaluate of grain yield and yield components on 42 rice lines tolerant to heat stress from international rice research instit...

This study assessed factors influencing consumer's preferences on rice attributes in Indonesia using data collected from a sample of 329 consumers South Sumatra Province Indonesia. used two variables such as independent and dependent variables. Independent predictor consumer include social-demographic On another side, rice-based the consumer. Social demographic gender, age, number families, occ...
