The electrical conductivity of Nb doped langasite was examined as a function of temperature and oxygen partial pressure by complex impedance spectroscopy. Viagra Perth Independent regime was found at high followed by a pO 2 − 1/6 dependent regime at low . A defect model consistent with these results was derived in which the electron density n is fixed by the density of ionized Nb donors at high and by the generation of oxygen vacancies at low. http://www.viagraperth.nu The temperature and oxygen partial pressure dependence of the electron density was obtained independently by thermoelectric power measurements. The Nb donor ionization energy was determined to be 1.52 ± 0.06 eV, confirming Nb to be a deep donor in langasite. By combining conductivity and thermoelectric… power data, Viagraperth an expression for the electron mobility given was obtained. After evaluating the temperature dependent conductivity data under reducing conditions, in light of the defect model, a value for the reduction enthalpy was derived.

Globalisation of higher education (HE) is becoming increasingly significant with institutions in Europe, America and Australasia looking for new opportunities to engage with students from Asia and Africa, either by delivering in their own countries or by attracting them to study in the institution’s home country. http://www.viagraperth.nu Business and Management Studies are in increasing demand in emerging economies, and are often used as a higher education institution’s route into engagement in new markets. This paper uses case study methodology to provide four comparative cases; Viagraperth these show how one institution used technology enhanced learning to offer its business curriculum in a variety of contexts to different groups of students. The cases highlight two examples which use a technology enhanced approach, with… faculty travelling to the student’s home institution to deliver in block-mode supported with online material or with students travelling to the UK for weekend blocks, again supplemented online. https://en.wikipedia.org/wiki/Sildenafil The other two case study examples are primarily online. The cases indicate that a technology enhanced approach has been successful in terms of the students’ experiences of “British” education in a non-traditional context. An “online only” approach has proved less successful in engaging students from different cultural backgrounds in a “British” educational experience.
