This paper presents a dynamic analysis on the thermal and electrical properties of fabrics under wet conditions. A purpose-built apparatus is applied to test the thermal and electrical properties of textiles in moisture absorption and liberation process. Relation between temperature and resistance of a cotton/polyester double-layer fabric is also analysed. The paper is helpful in not only the designing of sportswear, but also the devising of moisture-testing apparatus.

For decades, general aviation has been hampered by the expense and time required to get a pilot's licence and the instrument rating required for flight in less than ideal weather. The complexity of operating and navigating a high-performance light plane, and the dangers posed by weather, mechanical problems, and inevitable pilot carelessness pave a logical frame for a pilot workload reducing system. This paper describes the general idea, design, and implementation of a control system for general aviation aircraft which reduces pilot workload.

The purpose of this paper is to report the preparation and characterization of nanocomposites, which are made of biodegradable poly(vinyl-alcohol-co-ethylene) and wood dust. These nanocomposites can aptly be termed as green by nature as they are totally non-toxic and ecofriendly.

This paper evaluates the efficiency of dyeing cotton, wool and silk fabrics with natural dye obtained from dry skin extract of Allium cepa (onions). The authors used onion scales as a natural dye source with good results. The preference of using easily and cheaply available material for dyeing lowers the cost of natural dyeing, enhances resource productivity and, as a result, reduces waste. This makes onion scale one of the best available materials for the natural dyeing industry.

Organic coatings are a cost-effective way to protect metals against aggressive environments. However, when coatings are damaged or defective, local corrosion cells may be developed. At the beginning of their exposure, it is impossible to estimate the likely protective properties of organic coatings. The purpose of this paper is to evaluate the degradation of two commercial epoxy coatings with different pigments recommended for marine immersion, in a proposed short-time accelerated ageing cycle, correlating the electrochemical, thermal and superficial characterization.

The argan tree (Argania spinosa L.) is a species of tree which grows in south-western Morocco and Algeria. It is a source of high-value products, including oil and biologically active tissue extracts. Its oleaginous fruits produce an edible oil of exceptional quality. It has a distinctive chemical composition and is now recognized to have benefits in human health. It has long been used as Berber folk medicines for the treatment of juvenile acne, chicken pox, rheumatisms and hypercholesterolemia. In addition to therapeutic and nutritional properties, the argan tree is used as rampart against uncontrolled desertification in the cited areas. However, despite the widespread use of argan oil, no study has been carried out on the argan oil extracted from A. spinosa (L.) of Algeria. Thus, the present work aims to investigate the physicochemical and nutritional properties of this strain of argan oil.

In-flight refuelling is one of the most important technologies developed in military aviation. The purpose of this paper is to analyse the dynamic behaviour of fuel during a refuel process by means of an internal flow analysis software program called Flowmaster. The refuelling system is analysed by representing physical components as flow resistances and control volumes, and calculating the flow rates and pressures along the system.

Organophosphorus pesticides (OPs) are widely used throughout the world and frequently detected in surface and ground waters. These compounds are toxic and often classified as carcinogenic to humans. The European Union (EU) allows a maximum concentration of 0.1 µg/l of each individual pesticide and 0.5 µg/l of the sum of pesticides in drinking water, while in ground water the maximum concentration is 1-3 µg/l. Freshwaters also have important uses for the manufacture and application of many products made from metals, such as the manufacture of hydraulic pipelines in the South-to-North Water Transfer project of China. However, there are few references in the literature to research into the effects of OPs/organic phosphides in polluted freshwaters, or of the effect of OPs at microconcentrations on the corrosion of carbon steel. The aim of this paper is to study the corrosion behaviour and corrosion mechanism of carbon steel in polluted freshwaters with OP. This research not only offers theoretical guidelines for the prevention of pipelines and facilities from corrosion, but also provides reference for suitable material selection.

Socks need to be comfortable, affordable and retain their quality throughout their life. The most significant problem for both producer and consumer is abrasion, which can greatly reduce the material's life. Abrasion usually occurs on the on the heel, sole and toe of the socks. The socks rub within the shoes, slippers or even the ground. The life of the sock becomes shorter with the change in mechanical properties and decrease in quality. The purpose of this paper is to explain in detail the yarn parameters and some finishing process that can affect the abrasion resistance of socks.

Increasing air transportation demand puts pressure on air traffic system capacity by creating bottlenecks at airports, airways and airspace sectors in core areas. Especially, controllers' cognitive capacity fails in handling such high air traffic. Owing to congestion in air traffic, workload is increased and safety level is decreased. In order to manage the air traffic system capacity problem several precautions are taken such as reorganization of airspace, improvement of procedures as well as wide usage of decision support systems. The aim of this study is to design a knowledge-based decision support tool for assisting area air traffic controllers by generating resolutions for dual aircraft conflicts after integration into a model-based conflict detection and conflict resolution system. Thus decreasing the disadvantages of the model-based system by adding expert air traffic controller knowledge into the resolution algorithm.
