Celeganser: Automated Analysis of Nematode Morphology and Age

open access: yes, 2020
The nematode Caenorhabditis elegans (C. elegans) serves as an important model organism in a wide variety of biological studies. In this paper we introduce a pipeline for automated analysis of C.

A general kinetic model for the photothermal oxidation of polypropylene [PDF]

open access: yes, 2014
A general kinetic model for the photothermal oxidation of polypropylene has been derived from the basic auto-oxidation mechanistic scheme in which the main sources of radicals are the thermolysis and photolysis of the most unstable species, i.e ...

Synthesis and Characterization of Tungstite (WO3.H2O) Nanoleaves and Nanoribbons

open access: yes, 2014
An environmentally benign method capable of producing large quantities of materials was used to synthesize tungstite (WO3.H2O) leaf-shaped nanoplatelets (LNPs) and nanoribbons (NRs).

Ion-induced effects in GEM & GEM/MHSP gaseous photomultipliers for the UV and the visible spectral range [PDF]

open access: yes, 2005
We report on the progress in the study of cascaded GEM and GEM/MHSP gas avalanche photomultipliers operating at atmospheric pressure, with CsI and bialkali photocathodes.

Use of Alternative Wood for the Ageing of Brandy de Jerez [PDF]

open access: yes, 2020
The use of alternative types of wood has arisen for the aging of the Brandy de Jerez, on a pilot plant level. In particular, besides the use of American oak, two more types of oak have been studied, French oak and Spanish oak, allowed by the Technical ...

Age derivation from UV absorption indices and the effect of the UV upturn [PDF]

open access: yesProceedings of the International Astronomical Union, 2015
AbstractWe exploit stellar population models of absorption features in the ultraviolet to assess their power in determining the age of the stellar population in galaxies. We focus in particular on features that can differentiate between an old UV-bright population, contributing to the UV upturn, and a young population due to recent star formation.

Study on UV-aging performance of fluorinated polymer coating and application on painted muds

open access: yesMaterials Research Express, 2020
The UV-aging tests were carried out on synthetic fluorinated polymer coating (poly (methyl methacrylate)-poly (dodecafluoroheptyl methacrylate), FP) to study its UV-aging mechanism, UV-aging resistance and application on painted muds with calcium ...

Effects of wood fiber impulse-cyclone drying process on the UV-accelerated aging properties of wood-plastic composites.

open access: yesPLoS ONE, 2022
The impulse-cyclone drying and the silane coupling agent (A187) modification are applied to treat wood fibers under the following conditions: 180°C, 180°C+A187, 200°C+A187, 220°C+A187 and 240°C+ A187.

UV Aging in Plastics [PDF]

open access: yes, 2018
The purpose of this thesis is to find out the expected lifetime of radiation aged ther-moplastic material. The method is to irradiate PET and PP with UV radiation and measure the rate of degradation.

On the Lyman-alpha Emission of Starburst Galaxies [PDF]

open access: yes, 1993
Nearby starburst galaxies have consistently shown anomalous Ly-alpha/H-beta ratios. By re-analysing the published IUE/optical observations, we show that most starbursts present a normal Ly-alpha emission, consistent with case B recombination theory ...
