A complete analysis of light propagation through a hollow coupling with a uniformly varying cross section and specularly reflecting walls is given. This enables one to relate the entrance and exit intensity distributions when the input is incoherent but collimated. Results indicate that the input aperture can be partitioned into sections characterized by the total number of reflections an incom...

The different steps of the dehalogenation reaction carried out by LinB on three different substrates have been characterized using a combination of quantum mechanical calculations and molecular dynamics simulations. This has allowed us to obtain information in atomic detail about each step of the reaction mechanism, that is, substrate entrance and achievement of the near-attack conformation, tr...

The present research aims to explore metaphors used by pre-service English teachers as evidence for their thinking about “grammar”. A cohort of 47 partook in the study. were elicited both at beginning and end four-year education this interval paved way examining potential change participants’ beliefs over time. first clustered into two considering suggested definition grammar a phenomenon schoo...

In the winter of 1999, the University of Denver conducted a remote sensing study at Yellowstone National Park. The objective of the study was to identify the effect of oxygenated fuels on the exhaust emissions from snowmobiles. Ratios of CO, HC and toluene to CO 2 were measured and used to calculate %CO, %HC and parts per million of toluene. From the measured ratios we also calculated the grams...

During the pandemic, it has been seen that global population follows guidelines issued by health organization regarding wearing face masks, but some people do not take care of this and use masks. The objective proposed system, Wollega University Face Mask Detection System (WUFMDS), is to restrict who are a mask on door side identifying from or open if incoming person mask. This system based Int...

Understanding the molecular network of orderly mitotic exit to re-establish a functional interphase nucleus is critical because disordered mitotic exit inevitably leads to genomic instability. In contrast to the mechanisms of the entrance to mitosis, however, little is known about what controls the orderly exit from mitosis, particularly in mammalian cells. The chromosomal passenger complex (CP...

The mitochondrial ribosome is responsible for the biosynthesis of protein components crucial to the generation of ATP in the eukaryotic cell. Because the protein:RNA ratio in the mitochondrial ribosome (approximately 69:approximately 31) is the inverse of that of its prokaryotic counterpart (approximately 33:approximately 67), it was thought that the additional and/or larger proteins of the mit...

In South Korea, where mountainous terrain accounts for a significant proportion of the country, tunnels are essential reaching destinations via shortest possible route. Tunnels high-traffic areas with only two exits, making them vulnerable to large-scale disasters in event fire. However, existing longitudinal-flow-type exhaust systems (jet fans) insufficient effective smoke during tunnel Herein...
