A Study on the Effect of Plasma Modification on the Comfort Properties of Polyester/Cotton Blend Fabric
In this dissertation, the effect of cold plasma treatment on the comfort properties of P/C blend fabric has been studied in a low pressure plasma reactor. The plasma treatment was conducted on the samples of 65% polyester and 35% cotton blend fabric using argon, oxygen and air, separately, as well as mixtures of O2/HMDSO, N2/HMDSO, H2O/HMDSO and HMDSO monomer alone as working gases. Special attention was given to oxygen plasma due to its wide application for various textile/polymer materials. Due to this reason, the Taguchi method was used to design, analyze and optimize the oxygen plasma process. Other plasma parameters including working pressure, discharge power, duration of treatment and flow rate were also considered. The various comfort properties of plasma treated and untreated P/C blend fabric have been studied. In particular, thermal comfort such as, water vapor, air permeability, thermal resistance and wickability as well as tactile comfort including hand-feel and electro-physical properties were investigated. As the results showed that the oxygen plasma treatment had a positive effect on the thermal comfort and resistivity properties of P/C the blend fabric.
Plastic Waste for Sustainable Asphalt Roads
Waste polymers have been studied for various applications such as energy generation and biochemical production; however, their application in asphalt roads still poses some questions. Over the last decade, several studies have reported the utilization of waste plastics in roads using different methodologies and raw materials, but there is still significant inconsistency around this topic. What is the right methodology to recycle waste plastics for road applications? What is the correct type of waste plastics to be used in road applications? What environmental concerns could arise from the use of waste plastics in road applications? Plastic Waste for Sustainable Asphalt Roads covers the vario...

Big Tech and the Digital Economy
This book asks a simple question: are the tech giants monopolies? In the current environment of suspicion towards the major technology companies as a result of concerns about their power and influence, it has become commonplace to talk of Google, Facebook, Amazon, Apple, Microsoft, or Netflix as the modern day version of the 19th century trusts. In turn, the tech giants are vilified for a whole range of monopoly harms towards consumers, workers and even the democratic process. In the US and the EU, antitrust, and regulatory reform is on the way. Using economics, business and management science as well legal reasoning, this book offers a new perspective on big tech. It builds a theory of "mol...
Le Mangeur hypermoderne
Le micro-ondes et les portions individuelles, le péché de gourmandise, l’anorexie et l’obésité épidémiques, les McDo’s, le slow-food, le fooding, le traiteur à domicile, la gastronomie moléculaire : autant d’objets, de faits et de pratiques sociales qui révèlent les traits propres à la société contemporaine. Après ses travaux sur les villes, François Ascher poursuit son étude de la société « hypermoderne » en s’appuyant cette fois sur l’évolution des pratiques alimentaires. Il en tire des hypothèses ambitieuses et stimulantes sur le développement du modèle du restaurant, y compris à la maison, sur les relations entre sociabilité et pratiques alimentaires, sur l’émergence d’un nouveau groupe social, la « classe créative », pour laquelle la nourriture devient une question d’esthétique quotidienne, etc. Une véritable radiographie de la vie quotidienne d’aujourd’hui ; une réflexion originale sur la liberté des individus telle qu’elle s’exerce chaque jour. François Ascher est professeur à l’université Paris-VIII et à l’Université de Genève. Il est l’auteur de Métapolis.
