7075 T6 aluminum alloys are applied in aircraft construction. The success of their weldability is a technological challenge bringing advantages the lightening structures. This work was carried out aim to analyze mechanical behavior and microstructural evolution sheets welded by TIG process, applying pulsed current. A notable change occurred our materials thermal effect, resulting degradation pr...

This study aims to represent our clinical experience with several psychocutaneous disorders, such as trichotillomania, neurotic excoriation, dermatitis artefacta, and parasitic delusion. Lightening the human mind’s way of function has always been a challenge attracted medical interest through years. Psychodermatology recently received attention because different mechanisms psychoneuroimmunology...

Gilles Deleuze has become a key reference for the recent debate on virtual technologies, as his conception of is widely used to argue reality virtuality. Nonetheless some scholars, among which Slavoj Žižek stands out, have warned about risks flattening Deleuzian concept tech debate. This paper aims show why two concepts do not overlap by explaining features that make it incompatible with media....

As teachers we feel the need to do more than merely teach basic facts and concepts. We want to make the subject matter more relevant; we would like to help integrate the various threads of the students' education and life experiences; and, finally, we wish to increase the students' interest and involvement in the learning process. There is the temptation, however, when thinking along these line...

BACKGROUND The use of cryogen spray cooling in the course of dye laser treatment of port-wine stains has established itself in recent years because of its good analgesic and epidermally protective effects. The disadvantages of this kind of evaporative cooling are the cost and, in the case of dichlorodifluoromethane, the effects on the ozone layer. Cold air is an innovative cooling method that c...

Car body lightening and crashworthiness are two important objectives of car design. Due to their excellent performance, composite materials are extensively used in the car industries. In addition, reducing the weight of vehicle is effective in decreasing the fuel consumption. Hat shape energy absorber is used in car’s doors for side impact protection. The aim of these numerical models and expe...

In recent years, object detection has gained much attention and very encouraging research area in the field of computer vision. The robust object boundaries detection in an image is demanded in numerous applications of human computer interaction and automated surveillance systems. Many methods and approaches have been developed for automatic object detection in various fields, such as automotiv...

Background: There has been an increase in demand for cosmetic skin-whitening products with efficacy toward lightening skin tone. β-arbutin is inhibitor of tyrosinase enzyme activity within the skin’s melanocytes, and so shown considerable promise as a skin-lightening agent. It is, however, both hydrophilic hygroscopic, which hinders its penetration to reach these melanocytes. Chitosan (CS) poss...
