Analysis of the application of Socrative as a tool for the learning improvement in a subject of Experimentation in Chemical Engineering

[EN] Experimentation in Chemical Engineering III is a compulsory subject of the third course, semester B of the Chemical Engineering Degree at the Universitat Politècnica de València. It is the last experimental subject of the degree, and the methodology applied is "Project Oriented Learning" (POL). Students carry out experimental sessions, obtaining data that they later use to design an industrial installation based on the laboratory equipment but at a large scale. The course is assesed through the design project and a laboratory report of each experimental session, which is corrected by the teacher and then used as study material for the exam. Although the development of the subject is satisfactory, the teachers do not know the level that the students have about the experiment to be developed at the beginning of the experimental session and, in most of the cases, mistakes or errors of interpretation that they have had during the practice are detected during correction of the report. Therefore, last year teachers decided to introduce the use of the Socrative tool to conduct surveys to students at the beginning and the end of each session, in order to have real-time feedback on the points that should be most emphasized during the practice, as well as the degree of improvement achieved after the session. Socrative allows to carry out surveys in a simple way through the mobile phone, and to know at the same time the results of the assessment. Thus, students know their mistakes in the test before starting the experimental session, which also is useful to them to assess their level about the topic to develop and pay attention to find out those questions asked in the test in which they have obtained worse results. This work describes the implementation of this teaching innovation in the laboratory, as well as the results obtained and the degree of improvement achieved by comparing the results at the beginning and end of each experimental session. Finally, it is analysed the usefulness of the innovation, as well as the necessary improvements to continue its application in the future academic courses.García-Fayos, B.; Sancho, M.; Arnal Arnal, JM.; Zuriaga Agusti, E.; López-Hernández, I.

Thermal stability of N-(a ±-amino-dodecyl)-benzotriazole

N-(α-amino-alkyl)-benzotriazole, a derivative of Benzotriazole (BTZ), was synthesized via a Mannich reaction addition. The chemical characterization shows that when C19H32N4supramolecule is subjected to heating process the covalent bonds of aminal carbon are broken, modifying supramolecule structure, this results in a rearrangement to the structure dodecan ammonium-1-benzotriazol-1-ate, [BTZ- amine12+].Quantum chemical calculations based on DFT method were performed on the C19H32N4 molecule. The results show that in a derivative of BTZ exists a weak bond where its break may occur

Comparison between mixed liquors of two side-stream membrane bioreactors treating wastewaters from waste management plants with high and low solids anaerobic digestion

In the last years, biological treatment plants for the previously separated organic fraction from municipal solid wastes (OFMSW) have gained importance. In these processes a liquid effluent (liquid fraction from the digestate and leachate from composting piles), which has to be treated previously to its discharge, is produced. In this paper, the characteristics of the mixed liquor from two full-scale membrane bioreactors treating the effluents of two OFMSW treatment plants have been evaluated in view to study their influence on membrane fouling in terms of filterability. For that, the mixed liquor samples have been ultrafiltrated in an OF laboratory plant. Besides, the effect of the influent characteristics to MBRs and the values of the chemical and physical parameters of the mixed liquors on the filterability have been studied. Results showed that the filterability of the mixed liquor was strongly influenced by the soluble microbial products in the mixed liquors and the influent characteristics to MBR. Permeate flux of MBR mixed liquor treating the most polluted wastewater was considerable the lowest (around 20 L/m(2) h for some samples), what was explained by viscosity and soluble microbial products concentration higher than those measured in other MBR mixed liquor.

Psychometric Properties and factor structure of the spanish version of the HC-PAIRS questionnaire

Objective To develop a Spanish version of the Health Care Providers" Pain and Impairment Relationship Scale (HC-PAIRS) and to test its psychometric properties. Methods A forward and backward translation methodology was used to translate the questionnaire, which was then applied to 206 participants (174physiotherapy students and 32 family physicians). The intraclass correlation coefficient was calculated to assess testretest reliability. Internal consistency was evaluated using Cronbach"s alpha and item analysis. Construct validity was measured using Pearson correlation coefficients between HC-PAIRS and FABQ, FABQ-Phys, FABQ-Work and the responses given by participants to three clinical case scenarios. An exploratory factor analysis was carried out following the Kaiser normalization criteria and principal axis factoring with an oblique rotation (quartimax). Sensitivity to change was assessed after a teaching module. Results Testretest reliability was ICC 0.50 (p\0.01)and Cronbach"s alpha was 0.825. The HC-PAIRS scores correlated significantly with the scores of the FABQ and also with the recommendations for work and activity given by the participants in the three clinical case scenarios. Sensitivity to change test showed an effect size of 1.5, which is considered a large change. Factor analysis suggests that the Spanish version of HC-PAIRS measures a unidimensional construct. Conclusion The Spanish version of the HC-PAIRS has proven to be a reliable, valid and sensitive instrument to assess health care providers" attitudes and beliefs about LBP. It can be used in evaluating clinical practice and in undergraduate acquisition of skills and knowledge

Variation revealed by SNP genotyping and morphology provides insight into the origin of the tomato

Tomato, Solanum lycopersicum, is divided into two widely distributed varieties: the cultivated S. lycopersicum var. lycopersicum, and the weedy S. lycopersicum var. cerasiforme. Solanum pimpinellifolium is the most closely related wild species of tomato. The roles of S. pimpinellifolium and S. l. cerasiforme during the domestication of tomato are still under debate. Some authors consider S. l. cerasiforme to be the ancestor, whereas others think that S. l. cerasiforme is an admixture of S. pimpinellifolium and the cultivated S. l. lycopersicum. It is also not clear whether the domestication occurred in the Andean region or in Mesoamerica. We characterized 272 accessions (63 S. pimpinellifolium, 106 S. l. cerasiforme, 95 S. l. lycopersicum and 8 derived from hybridization processes) were morphologically and genetically using the SolCap platform (7,414 SNPs). The two species were distinguished in a PCA analysis and displayed a rich geographic structure. Solanum lycopersicum var. cerasiforme and S. l. lycopersicum were also differentiated in the PCA and Structure analyses, which supports maintaining them as different varieties. Solanum pimpinellifolium and the Andean S. l. cerasiforme were more diverse than the non-Andean S. lycopersicum. Solanum lycopersicum var. cerasiforme was morphologically and molecularly intermediate between S. pimpinellifolium and tomato. Solanum lycopersicum var. cerasiforme, with the exception of several Ecuadorian and Mexican accessions, is composed of the products of admixture processes according to the Structure analysis. The non-admixtured S. l. cerasiforme might be similar to the ancestral cultivars from which the cultivated tomato originated, and presents remarkable morphological diversity, including fruits of up to 6 cm in diameter. The data obtained would fit a model in which a pre-domestication took place in the Andean region, with the domestication being completed in Mesoamerica. Subsequently, the Spaniards took plants from Mesoamerica to Spain and from there they were exported to the rest of the world.Blanca Postigo, JM.; Cañizares Sales, J.; Cordero Romay, L.; Pascual Bañuls, L.; Díez Niclós, MJTDJ.; Nuez Viñals, F.

Brine recovery from hypersaline wastewaters from table olive processing by combination of biological treatment and membrane technologies

[EN] The fermentation brines from table olive processing (FTOP) are hypersaline effluents (conductivities higher than 75 mS·cm-1) with high organic matter concentrations (COD around 10 g·L-1), which also include phenolic compounds (between 700 and 1500 mg TY·L-1). In this work, an integrated process for the FTOP reuse as brine in the table olive processing has been evaluated. This integrated process consisted of a biological treatment followed by a membrane system, which included ultrafiltration (UF) plus nanofiltration (NF). The biological treatment was carried out by 6 L laboratory sequencing batch reactor (SBR). UF and NF were performed in laboratory plants for flat membranes of 0.0125 and 0.0072 m2, respectively. Each stream generated during the FTOP treatment (SBR effluent, and UF and NF permeates) were evaluated. The SBR eliminated around 80% of COD and 71% of total phenols concentration. In the final NF permeate the COD concentration was lower than 125 mg·L-1; while the turbidity, colour and phenolic compounds, were completely removed.The authors of this work thank the financial support of CDTI (Centre for Development Technological Industrial) depending on the Spanish Ministry of Science and Innovation.Ferrer-Polonio, E.; Carbonell Alcaina, C.; Mendoza Roca, JA.; Iborra Clar, A.; Alvarez Blanco, S.; Bes-Piá, M.; Pastor Alcañiz, L.
