Desenvolupament de línies experimentals per a la seva aplicació en els Treballs de finalització de Grau en Química
2012
Des del punt de vista acadèmic, els Treballs Fi de Grau en Ciències Químiques es presenten com a projectes experimentals relacionats amb problemes reals, orientats a progressar en coneixements i enfortir competències adquirides, convertint-se en claus del currículum per al món professional. S’aborden una sèrie de projectes integrals de laboratori com una aproximació més realista a l’aprenentatge integral. La metodologia docent proposta afavoreix la busca d’informació, pensament crític, superació contínua i èxit dels estudiants, semblant a la què es realitza en el món real, estimulant el seu interès i motivació durant el procés d’aprenentatge.
Principles and Elements of Risk Management – Data and Initial Conditions
2014
This chapter is devoted to furnishing background information on Risk Management, explaining the string of steps that comprise it, and the use of techniques within it, as well as their relationships. The chapter follows the widely accepted sequence for risk identification, assessment, execution, remediation and control; it starts with some basic definitions and, in its first topic, analyzes the sources for risks, considering internal and external risks and opportunities. It follows with a guide for identifying and managing risks in different areas of a project and suggests appropriate tools and techniques for each one. Completion of sequence sensitivity analysis, a subject developed in full …
Association between COX-2 rs 6681231 genotype and interleukin-6 in periodontal connective tissue. A pilot study.
2014
[Objectives] The aim of this pilot study was to investigate associations between IL-6 and COX-2 expression in gingival biopsies and both clinical diagnosis and genotypes in the IL-6 and COX-2 genes. [Design] A case-control study included 41 gingival biopsies obtained from Caucasian patients grouped according to clinical diagnosis of gingival health (n = 10), gingivitis (n = 15) or chronic periodontitis (n = 16). Immunohistochemistry analyses were performed to determine COX-2 expression in lamina propria, IL-6 expression in lamina propria and gingival epithelium and level of inflammatory cell infiltrate. Individual DNA was extracted and genotyped by real-time PCR for IL6 SNPs rs 2069827 and …
"Treatment is of primary importance, and social assistance is secondary": A qualitative study on the organisation of tuberculosis (TB) care and patie…
2018
Background Vulnerable individuals with tuberculosis (TB) struggle to access and stay on treatment. While patient-related and social barriers to TB treatment adherence are well documented, less is known about how the organisation and delivery of TB care influences adherence behaviour. Aim To examine the influence of TB service organisation and culture on patients’ experience of starting and staying on treatment in Riga, Latvia. Methods An intervention package to support adherence to TB treatment amongst vulnerable patients in Riga, Latvia was piloted between August 2016 and March 2017. Qualitative observations (5), interviews with staff (20) and with TB patients (10) were conducted mid-way a…
Sex in an uncertain world: environmental stochasticity helps restore competitive balance between sexually and asexually reproducing populations
2014
Like many organisms, individuals of the freshwater ostracod species Eucypris virens exhibit either obligate sexual or asexual reproductive modes. Both types of individual routinely co-occur, including in the same temporary freshwater pond (their natural habitat in which they undergo seasonal diapause). Given the well-known two-fold cost of sex, this begs the question of how sexually reproducing individuals are able to coexist with their asexual counterparts in spite of such overwhelming costs. Environmental stochasticity in the form of 'false dawn' inundations (where the first hydration is ephemeral and causes loss of early hatching individuals) may provide an advantage to the sexual subpop…
Treatment with electrical stimulation of sensory nerves improves motor function and disability status in persons with multiple sclerosis: A pilot stu…
2021
Abstract Declines in motor function are closely associated with decreases in sensory function in multiple sclerosis (MS). The purpose of our study was to assess the changes in motor function and disability status elicited by transcutaneous electrical nerve stimulation (TENS) to limb muscles of individuals with MS. Fifteen persons with MS and 11 age-matched healthy controls were evaluated before and after receiving 9 treatment sessions during which TENS was applied over the tibialis anterior and rectus femoris muscles of each leg, and over the median nerve and the thenar eminence of each hand. Each evaluation session involved completing two questionnaires (fatigue and walking limitations) an…
Assessing B.A.Bar Device as a Tool for Supporting Labour Integration of a Severely Affected Person with Autism Who Carries Out Classifying Tasks
2004
This paper describes the case research carried out to demonstrate the utility of a specific technical aid (adapted bar code reader) to train an adult with severe autism in the performance of a work task of classifying products in a shop. The individual with autism who participated in this research has a combination of difficulties (degree of 76 percent of disability and unable to learn to read and write) and abilities (being able to follow single verbal instructions). Positive results are expounded together with considerations about the desirable features of future products that would overcome the mere training process and also be useful for the final and real task in any working environmen…
Applicability of Interference Coordination in Highly Loaded HSUPA Network
2010
This paper evaluates the performance of highly loaded High Speed Uplink Packet Access (HSUPA) network with and without network wide static Interference Coordination (IC). IC alternates the priorities for user transmission periods throughout the network to achieve reduced interference levels and higher performance. A large variety of combinations including, e.g., different schedulers, cell center/edge user definitions (user splits) and interference targets are investigated in this paper. Performance is analyzed using a quasi-static system level simulator which is also used to support Third Generation Partnership Project (3GPP) standardization work. The simulator contains detailed and commonl…
TEACHING TO USE IN SCIENCE AND MATHEMATICS PREVIOUSLY ACQUIRED SKILLS
2016
Goal of the research is to analyse how students currently succeed in using basic skills acquired in mathematics, in science and real-life contexts, before new reforms in Latvia for the development of students' competence have been started. Only about 20% of students in the national testing for 9th grade were able to do it. The research analysed students’ papers, results, and study aids, as well as teacher performance in lessons.
Beyond Clicks and Beeps: In Pursuit of an Effective Sound Design Methodology
2007
Designing effective non-speech audio elements for a user-interface is a challenging task due to the complex nature of sounds and the changing contexts of non-visual interfaces. In this paper we present a design method, which is intended to take into account the complexity of audio design as well as the existing audio environment and the functional context of use. Central to this method is a rich use scenario, presented in the form of a radio play, which is used as a basis for the work of design panels. A previous version of the design method is analysed and specific practical issues are identified. Solutions to these issues are presented in the form of a modified version of the method. In t…
