E-cigarettes: Learnings for inhalation scientists: How studying e-cigarette technology may lead to new inhalation therapies

ECs share a common purpose with conventional pharmaceutical inhalation devices: they produce aerosols intended to be orally inhaled into the respiratory tract. They seemingly serve the same goal of pulmonary delivery so it is worthwhile to examine ECs from the viewpoint of inhalation drug development and explore what can be learned from them

PSEUDOELASTIC BEHAVIOUR AND TWO WAY MEMORY EFFECT IN Cu-Zn-Al ALLOYS

Different types of training sequences and two memory effect (TWME) of polycristalline Cu-Zn-Al alloys have been studied : Thin plates have been loaded in torsion and tests samples were loaded in pure tension. Simultaneous resistance measurements were made to know the volume fraction of the martensite. As Friend, it is shown that the first martensite platelets formed are the most operational for training. In addition, the relation between the pseudoelastic strain [MATH] and the martensite fraction z is non linear. The training can be quantified with the introduction of an internal kinematical stress [MATH
