An automatic correction tool for relational database schemas

A Web-based tool developed to automatically correct relational database schemas is presented. This tool has been integrated into a more general e-learning platform and is used to reinforce teaching and learning on database courses. This platform assigns to each student a set of database problems selected from a common repository. The student has to design a relational database schema and enter it into the system through a user friendly interface specifically designed for it. The correction tool corrects the design and shows detected errors. The student has the chance to correct them and send a new solution. These steps can be repeated as many times as required until a correct solution is obtained. Currently, this system is being used in different introductory database courses at the University of Girona with very promising results

Exploring chromium (VI) dioxodihalides chemistry: is density functional theory the most suitable tool?

A comparative systematic study of the CrO2F2 compound has been performed using different conventional ab initio methodologies and density functional procedures. Two points have been analyzed: first, the accuracy of results yielded by each method under study, and second, the computational cost required to reach such results. Weighing up both aspects, density functional theory has been found to be more appropriate than the Hartree-Fock (HF) and the analyzed post-HF methods. Hence, the structural characterization and spectroscopic elucidation of the full CrO2X2 series (X=F,Cl,Br,I) has been done at this level of theory. Emphasis has been given to the unknown CrO2I2 species, and specially to the UV/visible spectra of all four compounds. Furthermore, a topological analysis in terms of charge density distributions has revealed why the valence shell electron pair repulsion model fails in predicting the molecular shape of such CrO2X2 complexes

The hardness profile as a tool to detect spurious stationary points in the potential energy surface

The energy and hardness profile for a series of inter and intramolecular conformational changes at several levels of calculation were computed. The hardness profiles were found to be calculated as the difference between the vertical ionization potential and electron affinity. The hardness profile shows the correct number of stationary points independently of the basis set and methodology used. It was found that the hardness profiles can be used to check the reliability of the energy profiles for those chemical system

Fluvial biofilms: a pertinent tool to assess β-blockers toxicity

Among increasingly used pharmaceutical products, β-blockers have been commonly reported at low concentrations in rivers and littoral waters of Europe and North America. Little is known about the toxicity of these chemicals in freshwater ecosystems while their presence may lead to chronic pollution. Hence, in this study the acute toxicity of 3 β-blockers: metoprolol, propranolol and atenolol on fluvial biofilms was assessed by using several biomarkers. Some were indicative of potential alterations in biofilm algae (photosynthetic efficiency), and others in biofilm bacteria (peptidase activity, bacterial mortality). Propranolol was the most toxic β-blocker, mostly affecting the algal photosynthetic process. The exposure to 531 μg/L of propranolol caused 85% of inhibition of photosynthesis after 24 h. Metoprolol was particularly toxic for bacteria. Though estimated No-Effect Concentrations (NEC) were similar to environmental concentrations, higher concentrations of the toxic (503 μg/L metoprolol) caused an increase of 50% in bacterial mortality. Atenolol was the least toxic of the three tested β-blockers. Effects superior to 50% were only observed at very high concentration (707 mg/L). Higher toxicity of metoprolol and propranolol might be due to better absorption within biofilms of these two chemicals. Since β-blockers are mainly found in mixtures in rivers, their differential toxicity could have potential relevant consequences on the interactions between algae and bacteria within river biofilms

Allocation of GHG emissions in a paper mill, an application tool to reduce emissions

El sector de pasta i paper és considerat un dels set sectors industrials més intensius en consum energètic. La producció i consum d'electricitat i de vapor esdevenen les fonts majoritàries d'emissions de gasos d'efecte hivernacle en aquest sector industrial. Les fàbriques papereres poden assolir objectius de reducció d'emissions mitjançant reducció en origen (substitució de combustibles, introducció d'energies renovables) o bé a partir de mesures d'eficiència energètica en el propi procés. En aquest context, s'ha desenvolupat un mètode de distribució d'emissions que permet assignar a cada unitat d'operació del procés paperer, el seu grau de responsabilitat en emissions. També s'han avaluat diferents mètodes de càlcul de factors d'emissió de vapor i electricitat, tant per plantes de cogeneració com per sistemes individuals. A partir d'aquesta avaluació s'han proposat nous mètodes alternatius als analitzats. Aquests mètodes i els factors d'emissions s'han aplicat a dues fàbriques papereres catalanes.

Gestão estratégica de IES : modelos e funções do planejamento estratégico em universidades públicas e privadas de Palmas – Tocantins

O objetivo deste estudo foi de analisar os modelos e funções dos planejamentos estratégicos adotados nas instituições de ensino superior (IES) de Palmas, Tocantins. Procuramos, para tanto, enfatizar três grandes práticas empresariais globais que fazem parte do contexto das universidades: a competitividade, visualizada pela introdução da inovação e de novas tecnologias; a mercantilização da educação, que emergiu da forma como a educação é tratada - ‘mercadoria’- e, assim, reflete sobre a autonomia universitária; e, por último, o planejamento estratégico, que tomou grande proporção de uso no ensino superior nas últimas décadas. Frente ao exposto, a questão central que conduziu a pesquisa foi: como as práticas empresariais globais (planejamento estratégico, competitividade e mercantilização da educação) têm influenciado os modelos de gestão adotados pelas universidades frente aos desafios que enfrentam no tocante à oferta da educação superior e como os planejamentos estratégicos expressam essa influência? Nesse sentido, analisamos os documentos dos planejamentos estratégicos de duas IES, uma pública e outra privada, de forma a evidenciar suas diferenças e similaridades por meio dos modelos de gestão e suas principais funções, bem como entrevistamos os gestores das IES sobre suas concepções em relação à influência das práticas empresariais globais quanto ao planejamento estratégico. Como resultado das análises e das entrevistas realizadas, concluímos que o planejamento estratégico é utilizado, pelas IES, como importante ferramenta para formar a imagem institucional, pensar a universidade no futuro, evitar retrabalhos e, principalmente, melhorar os serviços prestados à sociedade.

Efficacy of the Speech Intelligibility Index as an intervention tool with pediatric cancer patients

This study evaluates the Speech Intelligibility Index (SII) as a tool to describe hearing loss and predict when hearing aids would be appropriate for pediatric oncology patients who have received or are currently receiving cisplatin. The efficacy of the SII is compared to the Brock grade which is commonly used for patients with ototoxic hearing loss secondary to cisplatin treatment. The SII is a discrete measure that precisely reflects the patient’s functional hearing status and is highly correlated with the need for audiologic intervention.
