In this paper, we report the combination of atomic layer deposition (ALD) with hydrothermal techniques to deposit ZnO on electrospun polyamide 6 (PA 6) nanofiber (NF) surface in the purpose of antibacterial application. The micro- and nanostructures of the hierarchical fibers are characterized by field emission scanning electron microscopy (FE-SEM), high-resolution transmission electron microsc...

Resuspension of uniform latex micro spheres deposited on a single seed pod of field rye grass stalk and head was investigated experimentally in a wind tunnel. The experiment was designed to distinguish aerodynamic (viscous and turbulent) mechanisms from mechanical resuspension resulting from the oscillatory impact of the grass hitting a stationary object. The experiment was run for deposited sp...

Nonalcoholic fatty liver disease (NAFLD), the prevalence of which is rising globally with current upsurge in obesity, is one of the most frequent causes of chronic liver diseases. The present study evaluated the ameliorative effect of extract of Tamarindus indica seed coat (ETS) on high fat diet (HFD) induced NAFLD, after daily administration at 45, 90, and 180 mg/kg body weight dose levels for...

The effect of L-tyrosine doping on various properties of potassium dihydrogen phosphate single crystals grown by slow cooling along with seed rotation method has been investigated. The crystalline nature of the grown crystals has been analyzed by powder X-ray diffraction analysis. The presence of various functional groups is identified by Fourier transform spectroscopy. Optical transparency of ...

Studies the effects of exposure to light of the laser diode Melles Griot (λ = 670nm), He-Ne laser (λ = 632.8nm) and argon laser (λ = 514nm) on selected soil micro-organisms, fungi that destroy old manuscripts, pictures, stone, etc. and on humification and mineralization of soil samples. Also studies exposure effects on seed growth and biomass production of a few species of cultivated plants and...

We discuss the guidance and control of the Samarai MAV—a single-winged, wholly rotating, biomimetic micro air vehicle developed at Lockheed Martin Advanced Technology Laboratories. Samarai is inspired by, and named after, the samara or maple seed Acer diabolicum Blume. It weighs 200 grams and consists of a single wing of radius 30 centimeters with an electric motor/propeller at the tip and torq...

LEA (late embryogenesis abundant) proteins were originally described almost 30 years ago as accumulating late in plant seed development. They were later found to be induced in vegetative plant tissues under environmental stress conditions and also in desiccation-tolerant micro-organisms and invertebrates. Although they are widely assumed to play crucial roles in cellular dehydration tolerance, ...

The Mexican jumping bean, Laspeyresia saltitans, consists of a hollow seed housing a moth larva. Heating by the sun induces movements by the larva which appear as rolls, jumps and flips by the bean. In this combined experimental, numerical and robotic study, we investigate this unique means of rolling locomotion. Time-lapse videography is used to record bean trajectories across a series of terr...

ABSTRACT It is recently proposed that cosmic rays generate a seed magnetic field in the early Universe. In this paper, we propose another generation mechanism of fields by rays, which Biermann battery driven resistive heating induced streaming rays. This dominant small-scale, low-temperature, and strongly ionized regions, compared with other previously mechanisms. Because are expected to be acc...

The advent of Next Generation Sequencing (NGS) technology has enabled a new major approach for micro RNAs (miRNAs) expression profiling through the so called RNA-Sequencing (RNA-Seq). Different tools have been developed in the last years in order to detect and quantify miRNAs, especially in pathological samples, starting from the big amount of data deriving from RNA sequencing. These tools, usu...
