A Novel Chaotic Image Encryption Algorithm Based on Latin Square and Random Shift. [PDF]
To realize the safe transmission of images, a chaotic image encryption algorithm based on Latin square and random shift is proposed. The algorithm consists of four parts: key generation, pixel scrambling, pixel replacement, and bit scrambling. Firstly, the key is generated from the plain image to improve the sensitivity of the encryption method ...

Landscape genetic structure of Scirpus mariqueter reveals a putatively adaptive differentiation under strong gene flow in estuaries. [PDF]
In this study, we analyzed the genetic structure of Scirpus mariqueter in the CRE and the QRE and estimated the effects of gene flow, divergent selection, and population colonization history on the structure based on AFLP data. Results showed that there was a moderate‐high level of genetic differentiation among populations, which was tested to be ...

Molecular dynamics simulations of the evaporation of hydrated ions from aqueous solution
Halide ions are present in the Earth’s atmosphere, but for the important case of fully or partially saturated water vapor it is not clear whether these ions are hydrated, i.e. surrounded by an adsorbed water layer, or not.

Electrochemical Behavior and Direct Quantitative Determination of Paclitaxel
The electrochemical behavior and direct quantitative determination of paclitaxel, a poorly soluble drug made into microemulsion, were researched by cyclic voltammetry in acetate buffer solutions (pH = 4.0) at a glassy carbon electrode.

NMR microscopy of tissue in organic and mixed solvents [PDF]
We propose to use organic and mixed solvents for nuclear magnetic resonance microscopy of fixed tissue as a means for improving image information content. NMR properties of some standard solvents (methanol, acetone, DMSO) and solvents in use for

Glicerol: um breve histórico e aplicação em sínteses estereosseletivas
Presently glycerol is considered a co-product of biodiesel industry. As the biodiesel production is exponentially increasing, glycerol generated from the transesterification of vegetable oils and fats is also being produced on a large scale, and turned ...

Application of ultrasound and methanol for rapid removal of surfactant from MCM-41 [PDF]
Ultrasound waves have been successfully applied for removing template from the mesoporous MCM-41 molecular sieve. The method uses a 28 KHz ultrasound irradiation in a methanol solvent for disrupting micellar aggregation of the surfactant ...
