Bandage contact lens use after photorefractive keratectomy
(Wolters Kluwer Health, 2019-08)
The use of a bandage contact lens (BCL) immediately after photorefractive keratectomy (PRK) results in less pain. This review analyzed which BCL is most effective in decreasing pain immediately after PRK and evaluated the ...

A unified approach to describe the thermal and magnetic hysteresis in Heusler alloys
(American Institute of Physics Publising LLC, 2016)
Different excitations, like temperature, magnetic field, or pressure, can drive a martensitic transition in Heusler alloys. Coupled phenomena in these materials lead to interesting magnetocaloric and barocaloric effects ...

Anisotropy field distribution in soft magnetic Hitperm alloys submitted to different field annealing processes
(Elsevier, 2016)
The magnetic anisotropy field distribution is discussed for Hitperm alloys annealed under different field conditions leading to different induced magnetic anisotropies: zero (ZF), transversal (TF), and longitudinal (LF) ...

Seasonal induction of cluster roots in Embothrium coccineum J.R. Forst. & G. Forst. in the field: factors that regulate their development
(Instituto de Investigaciones Agropecuarias, INIA, Chile, 2010)
Embothrium coccineum J.R. Forst. & G. Forst. (Proteaceae) is a tree that grows successfully in nutrient poor soils of southern Chile at full sunlight. Under these conditions it develops cluster roots (CR). However, the ...

Environmentally friendly monolithic highly-porous biocarbons as binder-free supercapacitor electrodes
(De Gruyter, 2018)
A simple, low-cost and environmentally friendly method has been used to obtain highly porous biomorphic carbon monoliths with a good combination of interconnected macro-, meso- and microporosity, and good electrical ...

Magnetocaloric response of amorphous and nanocrystalline Cr-containing Vitroperm-type alloys
(Elsevier, 2016)
The broad compositional range in which transition metal (TM) based amorphous alloys can be obtained, yields an easily tunable magnetocaloric effect (MCE) in a wide temperature range. In some TM-based alloys, anomalous ...

Core regulatory network motif underlies the ocellar complex patterning in Drosophila melanogaster
(Elsevier, 2015)
During organogenesis, developmental programs governed by Gene Regulatory Networks (GRN) define the functionality, size and shape of the different constituents of living organisms. Robustness, thus, is an essential ...

Enhanced carbon nanotube dispersion in 3YTZP/SWNTs composites and its effect on room temperature mechanical and electrical properties
(Elsevier, 2016-10)
In this work, several modifications of the colloidal processing technique and spark plasma sintering (SPS) to prepare yttria tetragonal zirconia composites (YTZP) with single walled carbon nanotubes (SWNT) have been ...
