The effect of material type, yarn count, pick density, type of mordant and layers of fabrics on the electromagnetic shielding properties of textile materials has been studied. The shielding effectiveness of the fabric is measured by estimating the insertion loss incurred to the signal when the sample is placed in the path of the signal at the frequency range 100 MHz-3 GHz inside the coaxial tra...

The quality of fibrous reinforcements used in composite materials can be monitored during the weaving process. Fibrous sensors previously developed in our laboratory, based on PEDOT:PSS, have been adapted so as to directly measure the mechanical stress on fabrics under static or dynamic conditions. The objective of our research has been to develop new sensor yarns, with the ability to locally d...

A field emission from a lateral emitter made by a multiwalled carbon nanotube (MWCNT) yarn was investigated. The lateral emitter showed an excellent field emission performance with a low turn-on electric field of 1.13 V/μm at an emission current of 1 μA, high emission current of 0.2 mA at an applied voltage of 700 V, and longtime emission stability for over 20 h without any significant current ...

Many factors such as production methods and structural parameters have distinctive influence on the quality and performance of a hand woven carpet. To investigate the effects of some variables, eighteen samples of carpet vary, in knot density, pile height and percentage of slipe wool, were manufactured. Pile yarn performance was assessed by using load-displacement compression curve, obtained fr...

The CEAs are sprayed, fan-like from a nozzled syringe onto severely burnt areas, prepared (ideally) with a patchwork of grafted skin. About half of the cells fall face down and grow because of the enzymes they secrete (being non-confluent), thus adhering to the recipient bed to proliferate. The beauty of Wood’s ‘spray-on skin’ (besides the speed of intervention so crucial for burns treatment), ...

Libraries and book publishers coevolved during the period of information scarcity, and developed cultural traits that are affecting their strategies in the new era of content abundance. Both industries are under threat. The author examines the interdependencies, the similarities, and the different agendas of the two cultures; explores likely speciation within the new ecosystems; and frames reas...

Mineral-based composites are presented as a real alternative to the use of Fiber Reinforced Polymer (FRP) composites. However, most studies have focused only on global mechanical behavior mineral-based The objective this paper is develop 3D numerical model in order predict and local tensile glass yarn/ettringitic matrix Two configurations been studied including dry pre-impregnated yarn. This mo...

Teaching ESL to adults means being awed every day as we witness the tenacity and perseverance of immigrants carving out better lives for themselves and their families. —Spelleri, 2002

In Part 1 of Greg Bear's science fiction novel “Darwin’s Children,” Kaye Rafelson, a scientist, virologist, and mother of a so-called “virus child” (a child born through a pregnancy induced by the SHEVA virus and therefore a mutant, a freak, a potentially dangerous creature) is reviewing a paper where she tries not only to demystify the myths and prejudices about viruses, but also to suggest an...

YARN (Yet Another RussNet), a project started in 2013, aims at creating a large open WordNet-like thesaurus for Russian by means of crowdsourcing. The first stage of the project was to create noun synsets. Currently, the resource comprises 100K+ word entries and 46K+ synsets. More than 200 people have taken part in assembling synsets throughout the project. The paper describes the linguistic, t...
