The effect of vibration therapy on neck myofascial trigger points: A randomized controlled pilot study
2020
[EN] Background: The purpose of this study was to evaluate the effect of low-frequency self-administered vibration therapy into myofascial trigger points in the upper trapezius and levator scapulae on patients with chronic non-specific neck pain. Methods: Twenty-eight patients with chronic non-specific neck pain were randomly assigned into a vibration group, receiving 10 self-applied sessions of vibration therapy in the upper trapezius and levator scapulae trigger points; or a control group, receiving no intervention. Self-reported neck pain and disability (Neck Disability Index) and pressure pain threshold were assessed at baseline and after the first, fifth and 10th treatment sessions. Fi…
Electronic and Functional Scope of Boronic Acid Derived Salicylidenehydrazone (BASHY) Complexes as Fluorescent Dyes
2017
[EN] A series of boronic acid derived salicylidenehydrazone (BASHY) complexes was prepared and photophysically characterized. The dye platform can be modified by (a) electronic tuning along the cyanine-type axis via modification of the donor-acceptor pair and (b) functional tuning via the boronic acid residue. On the one hand, approach (a) allows the control of photophysical parameters such as Stokes shift, emission color, and two-photon absorption (2PA) cross section. The resulting dyes show emission light-up behavior in nonpolar media and are characterized by high fluorescence quantum yields (ca. 0.5-0.7) and brightness (ca. 35000-40000 M-1 cm(-1)). Moreover, the 2PA cross sections reach …
Discrimination of nerve gases mimics and other organophosphorous derivatives in gas phase using a colorimetric probe array.
2012
A colorimetric array for the chromogenic discrimination of organophosphorous derivatives in gas phase has been developed. The array allows us to classify the nerve agent simulants DFP, DCP and DCNP.
(Re) Politizando la Solidariedad Internacional: Pensando la Cooperación como Educación para una Ciudadanía Global Radical
2017
[EN] The present moment of crisis regarding the identity and the resources of development aid calls for a deep reflection in order to recover the sense and the transformative aim of international development. In this work, we consider that we can recover a transformative agenda if we consider development aid as an space in which transformative learning processes take place. These learning processes lead to the construction of what can be called a ¿radical global citizenship¿. In development aid, individuals and organizations work together in social change processes. In these processes, people and organizations change through process of emergent and informal learning. Instead of considering …
Estudio de la Gestión de la Seguridad y Salud en el sector construcción valenciano
2015
[EN] Construction is a sector with a high accident rate due to its own characteristics (high component of labor and develops outdoor) and its organizational characteristics as working patterns, methods of implementation and higher outsourcing. Management of Health and Safety is a determining factor in obtaining best execution of work and lower rates of accidents. This paper presents a study of the current level of Health and Safety Management in the construction sector in Valencia (Spain) from a survey of a group of technicians with experience in the sector. The main results are the size of the company is an important key to health and safety, both in terms of training as in the management …
Determination of disproportionate tenders in public procurement
2013
[EN] Public procurement is one of the fundamental pillars of the construction sector and the understanding of its statutory regulation is one of the keys to success. The government regulates the concept of disproportionate tenders to avoid deals that are too low, something which could jeopardise the execution of the work or cause problems during implementation such as conflicting prices, project modifications and delays. The criteria for determining the disproportionality of the offers are numerous and each contracting authority determines which to use in each process by carrying out a comparative analysis. The results show that the formulas of disproportionality based on a percentage of th…
Rethinking capacity development for critical development practice. Inquiry into a postgraduate Programme
2012
Our proposal focuses on a theoretical framework intended to characterise and understand capacity development processes oriented towards the promotion of a critical development practice, an approach that faces the tensions between reformist and critical views of development management. This is what we call capacity development for emancipatory social change. From this viewpoint, we explore a postgraduate university programme in development management offered by the Universidad Politécnica de Valencia (Spain), with a twofold aim: first, to carry out an inquiry of the programme as a capacity development process in the training of critical development practitioners and second, to discuss the su…

Grassroots Social Innovation for Human Development: An Analysis of Alternative Food Networks in the City of Valencia (Spain)
2017
This paper explores the contribution the capability approach (CA) and grassroots innovation (GI) literature makes to a better understanding of the complexity, richness and specificity of bottom-up processes of social innovation (SI), and their specific contribution to social transformation. Using a purely qualitative methodology, the paper addresses a case study—organic food buying groups in the city of Valencia—and examines them through the lenses of SI, GI and CA. By taking four concurrent dimensions of the SI literature (agents, purposes, drivers and processes) and cross-fertilising them with the bottom-up, people-driven character of GI, and the concepts of agency, capabilities, delibera…
Risk Assessment of a compound feed process based on HAZOP analysis and linguistic terms
2016
[EN] The size and complexity of industrial plants, along with the characteristics of the products used, require a study, analysis and control of the existing risks in every industrial process. In this paper, a methodology for risk assessment in industrial plants, based on the combination of risks identification through the Hazard and Operability (HAZOP) analysis and the risks evaluation through linguistic variables and fuzzy numbers is applied to a case study consisting on a compound feed plant located in the town of Silla (Valencia, Spain). The results from this study show that the main risk in the compound feed production process is the formation of explosive atmospheres (ATEX). Therefore…
