Development of Low-Resistance Ohmic Contacts with Bilayer NiO/Al-Doped ZnO Thin Films to p-type GaN.

The fabrication of low-resistance and thermally stable Ohmic contacts is essential for the realization of reliable GaN power devices. In the particular case of p-type GaN, a thin Ni/Au bilayer is commonly used for Ohmic contacts. However, Au metal contacts are quite expensive, are incompatible with the complementary metal oxide-semiconductor foundries, and also have poor thermal stability.

Case Report and Literature Review of Giant Cutaneous Malignant Melanoma: What's Keeping Patients Away?

Giant cutaneous malignant melanoma (MM) is a term that has previously been used to define lesions that are at least 10 cm in diameter or 48 mm in thickness. Such tumours are rare. There is no substantial body of evidence considering why patients may delay presentation with MM until they reach this size.

Does 'Prison Napalm' work? Measuring the cooling temperature of sugar solution burns in a porcine model.

Non-accidental scalds sustained with sugar solution are potentially devastating and often associated with assaults within prisons where they are commonly known as 'Napalm' attacks. However, little is known about the mechanism behind such injuries. Proposed explanations have included a higher initial temperature, increased viscosity compared to water and lower emissivity, although these have yet to be demonstrated in any experimental model.

The first pelvic examination: A rite of passage for the women. A qualitative study about French women.

French general practitioners (GP) and gynaecologists can make use of recommendations when performing a patient's first pelvic examination. The indications and techniques for this examination are clear. The relational aspects and experience of the patients have been dealt with little.

Temporary Migration for Training: A Special Case.

Background: Against a background of globalization and medical migration, issues have been raised regarding training outside the clinician's own context.

Objective: There is a dearth of published literature on these issues and we aimed to explore these.

Methods: Taking Chang Gung Memorial Hospital fellowships in microfacial and craniofacial surgery as our case study, we developed an online survey to look at the circumstances leading junior doctors to seek specific, high-level training outside their country of intended practice and how effective this was for their future career, the service they provide, and their institutions.
