Research Regarding the Physical-Mechanical Properties of Knits for Garments – Abrasion Resistance
2017
Abstract During wear, the fabric is subjected to a complex combination of forces acting at various rates, in various intensities, in various directions and for various periods. This is one of the main causes of a fabric and garment becoming unacceptable for further wear. The main goal of this research paper is to improve the physical-mechanical properties of knits for garments by choosing the right fabric structure and raw material. The abrasion resistance is a mechanical deterioration and progressive loss of substance from a fabric, resulting from the fabric rubbing against itself or another surface. Tests was done on weft knitted fabric for garments using cotton, wool and mixed yarns, thr…
Middle Pleistocene protein sequences from the rhinoceros genus Stephanorhinus and the phylogeny of extant and extinct Middle/Late Pleistocene Rhinoce…
2017
BackgroundAncient protein sequences are increasingly used to elucidate the phylogenetic relationships between extinct and extant mammalian taxa. Here, we apply these recent developments to Middle Pleistocene bone specimens of the rhinoceros genusStephanorhinus. No biomolecular sequence data is currently available for this genus, leaving phylogenetic hypotheses on its evolutionary relationships to extant and extinct rhinoceroses untested. Furthermore, recent phylogenies based on Rhinocerotidae (partial or complete) mitochondrial DNA sequences differ in the placement of the Sumatran rhinoceros (Dicerorhinus sumatrensis). Therefore, studies utilising ancient protein sequences from Middle Pleis…
Non-conventional Ce:YAG nanostructures via urea complexes
2019
AbstractCe:YAG nanostructures (Ce:YAG = Cerium in Yttrium Aluminium Garnet), easy to control and shape, have been prepared via templating approach using natural and synthetic materials (i.e. paper, cotton wool and glass wool) previously soaked with a gel-like metals precursor and then thermally treated to achieve the wished morphology. The final material, otherwise difficult to process, can be easily moulded, it is lightweight, portable and forms, at the nanoscale, homogeneous layers of interconnected but not agglomerated nanoparticles (15 ± 5 nm). Using the same synthetic route, called Urea-Glass-Route, but in absence of a template, extremely pure Ce:YAG nanoparticle (45 ± 5 nm) can be als…

"Frater, ave atque vale" (Catull. 101.10): fortuna literaria de una fórmula epigráfica
2011
Trabajo realizado dentro del Grupo de Investigación «Tradiciones Clásicas» de la UPV/EHU (GIU-07-26) [ES] En este artículo ofrecemos un panorama con algunos de los autores modernos –Tennyson, Swinburne, V. Woolf, G. Moore, C.K. Stead y Anne Carson– que han dado nueva vida al motivo del saludo directo al difunto, a partir del carmen 101 de Catulo, cuyo verso 10 sigue gozando de un especial éxito, apoyado por la efectiva simplicidad de su saludo emotivo al hermano y de su forma, asequible y reconocible aun cuando el conocimiento de la lengua latina sea menor. [EN] In this article we offer an overview of some of the modern authors (specially Tennyson, Swinburne, V. Woolf, G. Moore, C.K. Stead,…
Effect of Sheep Wool Fibers on Thermal Insulation and Mechanical Properties of Cement-Based Composites
2019
The use of sheep wool as a filler of cement in order to produce mortar or plaster involves several advantages for environment and energy. Moreover, it is considered as a waste and, therefore, its use is characterized by low cost. The aim of this paper is to evaluate the influence of wool fibers on thermal conductivity and mechanical properties of cement. The samples were prepared using wool fibers, obtained from a breed of Sicilian sheep, with three different lengths (i.e., 1, 6, and 20 mm). Furthermore, in order to evaluate the influence of fiber content, the samples were prepared by varying the fiber weight fraction. The thermal conductivity of the samples was analyzed by using a heat flo…
Supercritical fluid extraction of pesticides
1989
The extraction behaviour of 10 μg samples of five pesticides and some related compounds from glass wool with supercritical CO2 has been investigated under several conditions (10 MPa, 20 MPa extraction pressure, 313 K, dry and water saturated CO2). The extraction fluid was decompressed over a line of little columns, filled with 3μ Si60 or RP18, and the amount of deposited material was analyzed by HPLC for each of these columns. Due to the progressive pressure/density reduction along the line, the solubility diminishes and hence the compounds are deposited according to their polarity/vapor pressure earlier or later on the line. Thus extraction and prefractionation of compounds of different po…
The ´champagne-cup` period at Carchemish. A review of the Early Bronze Age levels on the Acropolis Mound and the problem of the Inner Town.
2007
The pioneer excavations conducted by the British Museum expedition at the famous site of Carchemish in the 1910’s brought to light a large number of buildings, sculptures and inscriptions which provide an outline of the urban layout of the Iron Age city and its monuments. While many scholars have often attempted to re-examine the epigraphic material as well as the style and chronology of the major works of this period in order to set them in a proper historical context, much less attention has been paid to the earlier levels mainly uncovered on the Acropolis mound, ranging from the Neolithic to the Bronze Age. This paper discusses the archaeological evidence available and attempted to recon…
