Adoption and Adoption Interests of Self-Tracking Technologies : Single and Multiple Technology Perspectives
2016
During the past few decades, different forms of technology based self-tracking have become increasingly common but received little attention in academic research. In this study, we aim to address this gap by examining the adoption and adoption interests of four different self-tracking technologies: exercise, activity, sleep, and nutrition tracking. The examination is conducted from both single and multiple technology perspectives and by concentrating particularly on the potential gender and age dependencies in the adoption rates and adoption patterns of the technologies. By analysing the responses collected from 824 consumers through an online survey, the results of the study are able to re…
What drives travelers' adoption of user-generated content? : A literature review
2018
User-generated content (UGC) has become an important part of travel planning, as travelers evaluate travel products based on past reviews. However, different factors account for why tourists utilize UGC. The aim of this study is to review extant studies on UGC to identify the antecedents of UGC utilization for travel planning and the theories, models, and frameworks used in these studies. A total of 54 studies from 2005 to 2016 were found. This study found that UGC adoption is determined by attributes relating to the user, the source, the content, and response variables. It also found distinct and heterogeneous theories and frameworks mainly drawn from the information systems, socio-psychol…
H1-antihistamines suppress wheal-and-flare reaction and skin blood perfusion measured by Laser Dopppler flowmetry: randomized, double-blind, placebo-…

H1-antihistamines suppress wheal-and-flare reaction and skin blood perfusion measured by Laser Dopppler flowmetry: randomized, double-blind, placebo-controlled, crossover design study The aim of our study was to compare the influence of pre-treatment with H1-antihistamines (levocetirizine, desloratadine, clemastine, quifenadine, and sequifenadine) and a placebo on the histamine-induced weal and flare reaction, increase of skin blood perfusion and sedation. Thirty healthy volunteers were enrolled in the study. The study design was a prospective, randomised, double-blind, placebo-controlled, crossover, balanced clinical trial. Volunteers in randomised and double-blind order were treated with …

Adaptation of a tropical butterfly to a temperate climate
2018
Developmental plasticity enables organisms to cope with environmental heterogeneity, such as seasonal variation in climatic conditions, and is thought to affect a species’ capability to adapt to environments with novel seasonal and ecological dynamics. We studied developmental plasticity of the widespread tropical butterfly, Bicyclus safitza, which reaches the southern edge of its distribution in the temperate zone of South Africa. In wet–dry seasonal environments in tropical Africa, adults of Bicyclus butterflies are present all year round and exhibit discrete seasonal forms in alternating generations. We demonstrate that a population that colonized a more temperate climate region has adop…
Discovery of a new class of sortase a transpeptidase inhibitors to tackle gram-positive pathogens: 2-(2-phenylhydrazinylidene)alkanoic acids and rela…
2016
A FRET-based random screening assay was used to generate hit compounds as sortase A inhibitors that allowed us to identify ethyl 3-oxo-2-(2-phenylhydrazinylidene)butanoate as an example of a new class of sortase A inhibitors. Other analogues were generated by changing the ethoxycarbonyl function for a carboxy, cyano or amide group, or introducing substituents in the phenyl ring of the ester and acid derivatives. The most active derivative found was 3-oxo-2-(2-(3,4dichlorophenyl)hydrazinylidene)butanoic acid (2b), showing an IC50 value of 50 µM. For a preliminary assessment of their antivirulence properties the new derivatives were tested for their antibiofilm activity. The most active compo…
Putative sorting signals involved in PIN1 trafficking
2013
Las auxinas son hormonas vegetales involucradas en muchos procesos fisiológicos, tales como el crecimiento y diferenciación celular, la maduración de los frutos, la floración o los tropismos. Su transporte a través de la planta es polar, jugando un papel esencial en la regulación del crecimiento y el desarrollo y contribuyendo al mantenimiento de la polaridad global de la planta. La polaridad en el flujo de auxinas es debida, al menos en parte, a la distribución polar de los transportadores de salida de auxina de la familia PIN. En Arabidopsis thaliana se han identificado 8 transportadores PIN diferentes. Todos ellos presentan una estructura similar, con un dominio citosólico central que se…
Grupo de viviendas Santa María Micaela, S. Artal Ríos, Valenza 1958-1961
2009
Il progetto del complesso di 138 abitazioni di renta limitada Santa María Micaela, redatto per la cooperativa degli Agenti di Commercio di Valenza dall'architetto Santiago Artal Ríos, introduce una notevole variazione all'interno della pianificazione municipale, basata su una soluzione ad isolato tradizionale chiuso, proponendo l'edificiazione, all'interno della parcellarettangolare di 45,50x83,40 m, di tre blocchi residenziali: due di dodici piani con piano terra commerciale posti lungo i lati nord e ovest e uno di due piani sul lato sud, anch0esso dotato di servizi commerciali, allineati attorno ad uno spazio pubblico centrale di servizio
Pd2Au36(SR)(24) cluster: structure studies
2015
The location of the Pd atoms in Pd2Au36(SC2H4Ph)(24), is studied both experimentally and theoretically. X-ray photoelectron spectroscopy (XPS) indicates oxidized Pd atoms. Palladium K-edge extended X-ray absorption fine-structure (EXAFS) data clearly show Pd-S bonds, which is supported by far infrared spectroscopy and by comparing theoretical EXAFS spectra in R space and circular dichroism spectra of the staple, surface and core doped structures with experimental spectra.
Overexpression of SAMDC1 gene in Arabidopsis thaliana increases expression of defense-related genes as well as resistance to Pseudomonas syringae and…
2014
It has been previously described that elevation of endogenous spermine levels in Arabidopsis could be achieved by transgenic overexpression of S-Adenosylmethionine decarboxylase (SAMDC) or Spermine synthase (SPMS). In both cases, spermine accumulation had an impact on the plant transcriptome, with up-regulation of a set of genes enriched in functional categories involved in defense-related processes against both biotic and abiotic stresses. In this work, the response of SAMDC1-overexpressing plants against bacterial and oomycete pathogens has been tested. The expression of several pathogen defense-related genes was induced in these plants as well as in wild type plants exposed to an exogeno…
