Seeds of carrot, groundnut, lettuce, oilseed rape and onion were stored hermetically in laminated aluminium foil packets in four environments (dry or ultra-dry moisture contents combined factorially with temperatures of 20°C or -20°C), replicated at several sites. After ten years’ hermetic storage, seed moisture content, equilibrium relative humidity, viability (assessed by ability to germinate...

Summary: Low frequency ultrasound in combination with Sodium Lauryl Sulphate (SLS), a known transdermal chemical enhancer has been found to enhance delivery of molecules through the skin. In this abstract, we report the effects of changing SLS concentration on cavitation, protein permeation through the skin and skin damage. Introduction: Low-frequency ultrasound (US), applied to skin via a liqu...

Waterpipe smoking, a tobacco consumption method traditionally associated with the Middle East and South Asia, has increased in prevalence in the last decade in Europe and the US, especially among young people (Amin et al., 2010; Al-Naggar; Saghir, 2011; Martinasek et al., 2011). The waterpipe apparatus consists of a head, body, bowl and hose. The head is loaded with a 10-20 gram of fruit-flavou...

Direct microjoining using Yttrium-Aluminium-Garnet (YAG) laser beams of copper wire and a plate or substrate board was carried out. The control of the behavior of the molten wire was extremely important to prevent joining defects such as evaporation or constriction of the wire. Both the contact angle between the wire and the plate and the distance from the tip of the wire to the laser irradiati...

Aluminium foil is a thin material made of aluminum metal used for packaging. has good properties packaging food products, including hermetic, flexible, opaque, impervious to moisture and water, non-flammable, does not absorb other materials or substances. Widely, aluminium as coating, especially which must be protected from gas, moisture, odors, light so that it can better maintain the durabili...

A base aluminium-silicon alloy AlSi25Cu5Cr was used to investigate the possibility of alloying aluminium alloys with hard-to-melt elements. The elements Co, Cr and Mo were introduced into melt using metal powder from a hard-melting dental cobalt-chromium-molybdenum alloy. packed in foil studied at temperature 810º C. After mechanical stirring melt, it stood for 30 min. temperature, raised 850º ...
