Cesium radioactive isotopes (134Cs and 137Cs) are dangerous to human health due to their long half-life and high solubility in water. Nuclear experiments, wars, and nuclear plant accidents have been the main sources of Cs release into the environment. In recent years, several methods have been introduced for the elimination of Cs radioactive isotopes from contaminated wate...

Two vegetable wastes, cork bark and grape stalks, were investigated for the removal of methylene blue from aqueous solution. The effects of contact time, dye concentration, pH, and temperature on sorption were studied relative to adsorption on a commercially-activated carbon. The highest adsorption yield was obtained within the pH range 5 to 10 for grape stalks and 7 to 10 for cork bark. The so...

Industrial graphite becomes waste after its use and dumping of such leads to environmental damage health risks, thus needs alternative measures. This study is the first kind convert industrial exfoliated graphene(EG) using EG as an adsorbent. The used conversion method chemicothermal which greener competent. resultant was micro-analyzed for application engineered adsorption capacity tested remo...

For \(k \ge 2\), an ordered k-uniform hypergraph \(\mathcal {H}=(H,<)\) is a H together with fixed linear ordering < of its vertex set. The Ramsey number \(\overline{R}(\mathcal {H},\mathcal {G})\) two hypergraphs {H}\) and {G}\) the smallest Open image in new window such that every red-blue coloring hyperedges complete {K}^{(k)}_N\) contains blue copy or red {G}\).

The radical pair model proposes that the avian magnetic compass is based on radical pair processes in the eye, with cryptochrome, a flavoprotein, suggested as receptor molecule. Cryptochrome 1a (Cry1a) is localized at the discs of the outer segments of the UV/violet cones of European robins and chickens. Here, we show the activation characteristics of a bird cryptochrome in vivo under natural c...

BACKGROUND This study aimed to identify more potential genes and miRNAs associated with the pathogenesis of intracranial aneurysms (IAs). MATERIAL AND METHODS The dataset of GSE36791 (accession number) was downloaded from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) were screened for in the blood samples from patients with ruptured IAs and controls, followed by fu...

For graphs G,F and H we write G → (F,H) to mean that if the edges of G are coloured with two colours, say red and blue, then the red subgraph contains a copy of F or the blue subgraph contains a copy of H. The graph G is (F,H)-minimal (Ramsey-minimal) if G → (F,H) but G′ 6→ (F,H) for any proper subgraph G′ ⊆ G. The class of all (F,H)-minimal graphs shall be denoted by R(F,H). In this paper we w...

LATEX by Adam Jobson For a family of graphs F closed under subgraphs, and a graph G from F , define a game (G,F) played by Builder and Painter. The game begins with Builder presenting an edge and Painter coloring the edge red or blue. On each turn thereafter, Builder adds another edge to the red-blue colored graph present (adding vertices if needed), so that the new graph, viewed uncolored, is ...

Experiments are an important part of the chemistry curriculum. An indicator in form a synthesis is commonly used acid-base materials experiments. The usage synthetic indicators can result waste that both environmentally harmful and costly. butterfly pea flower one plants contains anthocyanins, which have potential to be as alternative indication natural acids bases. study aims determine acid ba...

Zebrafish are tetrachromats with red (R, 570 nm), green (G, 480 nm), blue (B, 415 nm), and UV (U, 362 nm) cones. Although neurons in other cyprinid retinas are rich in color processing neural circuitry, spectral responses of individual neurons in zebrafish retina, a genetic model for vertebrate color vision, are yet to be studied. Using dye-filled sharp microelectrodes, horizontal cell voltage ...
