The golden ratio is the ratio we consider perfect and good-looking.It divides a line segment into two unequal parts so that the ratio of the length of the larger line segment to the smaller one is equal to the ratio of the whole length to the longer length of line segment.This ratio is approximate 1,618 and has infinitely many decimal places.The ar
Inert gas agents have the potential to be widely used in fire suppression systems due to health and safety concerns associated with active chemicals.To suppress fire while minimizing hypoxic effects in an occupied area, the discharge quantity Dishes of inert gas agents should be carefully designed to dilute the oxygen concentration to a specific th
High-speed motions performed by industrial machines can induce severe vibrations that degrade the positioning accuracy and efficiency.To address this issue, this paper proposes a novel motion profile design method utilizing a sinusoidal jerk model to generate fast and smooth motions Goldenrod with low vibrations.The expressions for the acceleration
The Caenorhabditis elegans MES proteins are key chromatin regulators of the germline.MES-2, MES-3, and MES-6 form the C.elegans Polycomb repressive complex 2 and generate repressive H3K27me3.MES-4 generates H3K36me3 on germline-expressed genes.Transcript profiling of dissected mutant germlines revealed that MES-2/3/6 and MES-4 cooperate to promote
Long-term researches of specific activity of 137Cs at a pike perch (Lucioperca lucioperca L.) from Kanevskoe reservoir and cooling-pond of ChNPP are summed up.Distribution of 137Cs on organs and tissues of a pike perch occurred more slowly, than at the majority of other species of Table Paper fishes.It is established that water temperature does not
