Self-Healing E-tongue.

Self-healing materials inspire the next generation of multifunctional wearables and Internet of Things appliances. They expand the realm of thin film fabrication, enabling seamless conformational coverage irrespective of the shape complexity and surface geometry for electronic skins, smart textiles, soft robotics, and energy storage devices. Within this context, the layer-by-layer (LbL) technique is versatile for homogeneously dispersing materials onto various matrices.

Electronic Tongues for Inedible Media.

"Electronic tongues", "taste sensors", and similar devices (further named as "multisensor systems", or MSS) have been studied and applied mostly for the analysis of edible analytes. This is not surprising, since the MSS development was sometimes inspired by the mainstream idea that they could substitute human gustatory tests. However, the basic principle behind multisensor systems-a combination of an array of cross-sensitive chemical sensors for liquid analysis and a machine learning engine for multivariate data processing-does not imply any limitations on the application of such systems for the analysis of inedible media.

3D Printed e-Tongue.

Nowadays, one of the biggest issues addressed to electronic sensor fabrication is the build-up of efficient electrodes as an alternative way to the expensive, complex and multistage processes required by traditional techniques. Printed electronics arises as an interesting alternative to fulfill this task due to the simplicity and speed to stamp electrodes on various surfaces. Within this context, the Fused Deposition Modeling 3D printing is an emerging, cost-effective and alternative technology to fabricate complex structures that potentiates several fields with more creative ideas and new materials for a rapid prototyping of devices.

[József Brandt, school-founding professor of surgery -- for the centennary of his death].

The present article outlines the biography of the great Transylvanian surgeon József Brandt and appraises his professional work. After his medical training in Vienna and specialisation in surgery Brandt returned to Kolozsvár (now: Cluj/Romania) in 1867 to teach surgery and ophthalmology at the Medical-Surgical Institute of this town. As soon as the Royal Hungarian University in Kolozsvár was opened in 1872, Brandt was appointed as professor of the Department of Surgery.

The relationship between pacifier use, bottle feeding and breast feeding.

Objective: To investigate the influence of pacifier use and the introduction of formula milk on breast feeding.

Methods: The mothers of 356 healthy newborn infants who initiated breast feeding while in-patients were interviewed within 3 days of birth and later at 2 and 6 months postpartum. Information regarding previous birth, breast-feeding frequency, pacifier use and the adoption of formula milk were obtained.
