Comparison of Luminescence in LiGaO2, Al2 O3 -Ga and Al2 O3 -Li Crystals
2018
We have studied luminescence of LiGaO 2 , Al 2 O 3 -Ga and Al 2 O 3 -Li crystals in order to reveal the nature of luminescence centres and mechanisms in these crystals. In Al 2 O 3 -Ga presence of Ga impurities determines occurrence of the 280 nm emission band, which demonstrates intra-centre character in photoluminescence and recombination character under X-ray irradiation. In Al 2 O 3 -Li crystal lithium induced luminescence is presented with the 326 nm band, which has a recombination character. Basing on spectral similarity of the main luminescence bands in pure LiGaO 2 crystal with the dopant-induced emission bands in Al 2 O 3 , and on peculiarities of the X-ray induced thermoluminescen…
Dynamic Refolding of Ion-Pair Catalysts in Response to Different Anions.
2019
Four distinct folding patterns were identified in two foldamer-type urea-thiourea catalysts bearing a basic dimethylamino unit by a combination of X-ray crystallography, solution NMR studies, and computational studies (DFT). These patterns are characterized by different intramolecular hydrogen bonding schemes that arise largely from different thiourea conformers. The free base forms of the catalysts are characterized by folds where the intramolecular hydrogen bonds between the urea and the thiourea units remain intact. In contrast, the catalytically relevant salt forms of the catalyst, where the catalyst forms an ion pair with the substrate or substrate analogues, appear in two entirely dif…

La historiografía reciente sobre el primer carlismo (2006-2018)
2020
The objective of this article is to analyze the latest publications on the first Carlism and to know what the current state of affairs is. To do this, more than 300 works have been consulted and the authors, the study topics and the interpretations have been analyzed. In this way we see that there are three types of historians of Carlism and that the group to which they belong influences the kind of publications, the themes and the interpretations of each one. As for the subjects, there is a great variety of them, being the most frequent the biographies, the military accounts and the local, county and historiographic studies. On the other hand, although there are new approaches and some gap…
Reporting in Conflict Zones in Pakistan: Risks and Challenges for Fixers
2020
As a backbone of reporting in war and conflicts, fixers offer essential assistance to the foreign correspondent in conflict zones, also in Pakistan. With valuable local knowledge and contacts, fixers can arrange travel to secure entry of foreign correspondents into conflict zones in addition to securing interviews with otherwise unattainable figures, while offering reliable translation services. Pakistani media, despite being one of the largest and most developed in South Asia, remains under the strict control of powerful military establishment and government, while seeming to mirror the overarching government sentiment with a distinct lack of research-based news. Challenging this state of …

Evaluation of interface pressure and temperature management in five wheelchair seat cushions and their effects on user satisfaction
2020
Abstract Background Factors such as the manufacturing materials, shape or even the mechanical and thermal response of sitting Pressure Redistribution Support Surfaces (PRSS) can be potential contributors to pressure ulcers. However, few studies have compared a number of characteristics of the most frequently used devices. Objective To compare three potential contributors to pressure ulcers in five commercial PRSS: pressure redistribution, temperature and perceived comfort. Method: Study with a cross-over randomized design in healthy volunteer participants. Data was collected in a temperature and relative humidity controlled environment. To assess thermal response, the temperature (Flir-E60)…
Effects of a Rehabilitation Program on Perceived Environmental Barriers in Older Patients Recovering from Hip Fracture: A Randomized Controlled Trial
2013
Objectives. To study effects of a one-year multicomponent intervention on perceived environmental barriers in hip fracture patients.Design. Randomized controlled trial of a 12-month home-based rehabilitation aiming to improve mobility and function (ISRCTN53680197); secondary analyses.Subjects. Community-dwelling hip fracture patients on average 70 days after trauma (n=81).Methods. Assessments at baseline, 3, 6, and 12 months later included perceived entrance-related barriers (e.g., indoor/outdoor stairs, lighting, floor surfaces, and storage for mobility devices) and perceived barriers in the outdoor environment (poor street condition, hilly terrain, long-distances, and lack of resting plac…
Identifying physical activity type in manual wheelchair users with spinal cord injury by means of accelerometers
2015
Objectives: The main objective of this study was to develop and test classification algorithms based on machine learning using accelerometers to identify the activity type performed by manual wheelchair users with spinal cord injury (SCI). Setting: The study was conducted in the Physical Therapy department and the Physical Education and Sports department of the University of Valencia. Methods: A total of 20 volunteers were asked to perform 10 physical activities, lying down, body transfers, moving items, mopping, working on a computer, watching TV, arm-ergometer exercises, passive propulsion, slow propulsion and fast propulsion, while fitted with four accelerometers placed on both wrists, c…
Trichoscopy features of trichotillomania
2019
Trichotillomania is a form of traction alopecia resulting from repetitive and compulsive hair pulling and plucking. Trichotillomania and patchy alopecia areata may have similar clinical and dermoscopic features in some cases. On trichoscopic examination, the presence of black dots, coiled or hook hair, shafts of varying lengths with fraying or split ends (trichoptilosis), and an absence of exclamation mark hairs and yellow dots are suggestive of trichotillomania.
