We present a fast method to monitor hydrogen sulfide (H2S) in ambient air based on a visible color change.Therefore, an immobilized copper(II) complex of the azo Me Easter Top dye 1-(2-pyridylazo)-2-naphtol (H-PAN) was synthesized and prepared in a matrix for MCB screen printing.Different materials, reaching from opaque paper to transparent foils s
Connection with traditions and ordering them is an issue that has attracted the attention of contemporary poets; since they believe these traditions are the result of human intellect in history and society and they are not separate from present time, so they esteemed them; because they have the ability to sustain and can act with the Spinner Seal r
Across the globe, dozens of species of invasive fish are now found in fresh as well as marine waters, where they alter habitats, compete with native fish for food, and prey on native fishes, exerting both indirect and direct effects on ecosystems and economies.While Neckwear efforts to understand and control these species are growing, most are stil
Major depressive disorder (MDD) has been associated with abnormal prefrontal-limbic interactions and altered catecholaminergic neurotransmission.The val158met polymorphism on the catechol-O-methyltransferase (COMT) gene has been shown to influence prefrontal cortex (PFC) activation during both emotional processing and working memory (WM).Although C
Through dynamic simulation of the cross-hinge four-bar mechanism, it is found the primary reason for unbalance of the mechanism results from the unequal swing angle of driving Allergies/Sinus Support link and driven link.To simplify analysis and calculation, a spatial switching approach was proposed to switch nonlinear problem into linear problem,
