Acoustically semitransparent nanofibrous meshes appraised by high signal-to-noise-ratio MEMS microphones.

Microelectromechanical system-based microphones demand high ingress protection levels with regard to their use in harsh environment. Here, we develop environmental protective components comprising polyimide nanofibers combined onto polyether ether ketone fabric meshes and subsequently appraise their impact on the electroacoustic properties of high signal-to-noise-ratio microelectromechanical system-based microphones via industry-standard characterizations and theoretical simulations. Being placed directly on top of the microphone sound port, the nanofiber mesh die-cut parts with an inner diameter of 1.

Hydrocephalus of King Charles II of Spain, the Bewitched King.

King of the Spanish Habsburg dynasty and sovereign of the overseas Spanish Empire, Charles II of Spain, was physically disabled, disfigured, mentally retarded, and he proved impotent. He is known in history as El Hechizado (the Bewitched) because both him and the people believed that his mental and physical incapacity were due to a "witchcraft act." Although several authors speculated about different diseases, most of them genetic such as pituitary hormone deficiency, distal renal tubular acidosis, Klinefelter syndrome, fragile X syndrome, or male XX hermaphroditism, the hypothesis of hydrocephalus was not taken into account.

Double stapled haemorrhoidopexy for haemorrhoidal prolapse: indications, feasibility and safety.

Aim: Selected patients with haemorrhoidal prolapse undergoing double stapled anopexy with the procedure for prolapse and haemorrhoids (PPH03) were studied.

Method: Between March 2007 and March 2010, 235 patients referred with haemorrhoids were included in the study. Patients with obstructed defaecation were excluded.

Fast on-wafer electrical, mechanical, and electromechanical characterization of piezoresistive cantilever force sensors.

Validation of a technological process requires an intensive characterization of the performance of the resulting devices, circuits, or systems. The technology for the fabrication of micro and nanoelectromechanical systems (MEMS and NEMS) is evolving rapidly, with new kind of device concepts for applications like sensing or harvesting are being proposed and demonstrated. However, the characterization tools and methods for these new devices are still not fully developed.

[Quality improvement, training and clinical governance: the role of the chief medical officer and his staff].

Purpose: To allow chief medical officers and their staff to contribute to implemented quality and clinical governance programs and consequently give a more precise identity, in terms of prestige and professional value, to a Structure that can contribute significantly to the development of a high quality hospital.

Methods: Terminology used was briefly described; tasks assigned to the chief medical officer and staff were then analysed and lastly, a hypothetical integrated training program was outlined for directors/managers.

Conclusions: Quality and professional training represent important tools for human resources management policy.
