Los hábitos lectores en inglés de futuros maestros: Implicaciones didácticas
2014
Se presenta un estudio exploratorio y descriptivo sobre los hábitos lectores en inglés de estudiantes universitarios españoles para detectar cuáles son las áreas de atención prioritaria para poder seguir un Grado en inglés según el EEES. Se midió el nivel de inglés mediante el Oxford Online Placement Test. Se evaluaron los hábitos lectores y el tipo de materiales académicos que los estudiantes leen en inglés mediante un cuestionario. Gran parte de la muestra se encontraba en los niveles elementales e intermedios de dominio del inglés. Un porcentaje muy elevado de estudiantes declaró no tener el hábito de leer en inglés y leer solo materiales académicos obligatorios. Sin embargo, existe una …
Marginal abatement cost of carbon dioxide emissions in the provision of urban drinking water
2021
Abstract Reducing greenhouse gas emissions is a major challenge faced by cities seeking to improve their environmental sustainability. Doing so requires a good understanding of the costs associated with lowering emissions and factors that may influence this cost. This study estimated the marginal abatement cost of reducing both direct and indirect CO2 emissions in the provision of drinking water by several water companies in England and Wales. The results indicated that during the years 2013–2018, the average cost to the English and Welsh water industry to prevent 1 kg of CO2 emissions was 0.264₤ which was equivalent to 61% of the price of the delivered drinking water The results of the Mor…
A Prototype of Wireless Sensor for Data Acquisition in Energy Management Systems
2018
A prototype of a wireless sensor for monitoring electrical loads in a smart building is designed and implemented. The sensor can acquire the main electrical parameters of the connected load and, optionally, other physical quantities (e.g., room temperature). Unlike other wireless sensors in literature, the proposed sensor is cheap and small, exploits the Wi-Fi network that is commonly available inside buildings, and uses a lightweight message-based communication paradigm. Besides the sensor node, two management nodes are also implemented to manage sensor reconfiguration and the persistence of data. The measured data are stored in an SQLite database and can be used for various purposes, e.g.…
Comparative analysis and antimicrobial action of some essential oils from plants
2021
In this research, essential oils (EOs) were extracted through steaming from aerial parts of three plants: basil (Ocinum basilicum L.), peppermint (Mentha piperita L.) and oregano (Origanum vulgare L.) form Sibiu County, Romania. The GC-MS analysis indicated that eugenol and apiol were the major compounds in the basil EO. Timol, ɣ-terpinene, and p-cymene were the major compounds in the volatile oil extracted from oregano and menthol and methone the main components in the peppermint EO. In the first 48 h of analysis, basil EO inhibition action was the highest against Salmonella anatum (48%), followed by Aspergillus niger (26%), Bacillus cereus (21%) and Saccharomyces cerevisiae (15%); this ac…
Histoire et évolution des appellations d'origine françaises
2019
During the 20th century, wine appellations of origin have largely developed to represent a significant part of the wine production of some countries, especially in Europe. The globalization of the production, trade and consumption of wine is a major fact of the 21st century economy. The question of appellations of origin and more generally geographical indications must be asked: Is it a survival 100 years after the first law on appellations of origin was adopted in France? Historical knowledge makes it possible to understand how law, both national and international, has been marked by major developments in this area. Regulations on the origin of products have undergone significant changes o…
L'histoire du vin comme patrimoine et atout économique
2017
La connaissance historique du vin est aujourd'hui un enjeu scientifique, culturel mais aussi economique. La precocite du commerce international et de la consommation du vin dans de nombreuses regions du monde permet d'avoir une reflexion en longue duree – sur plusieurs siecles – concernant la globalisation. Au 20e siecle l'instauration de normes internationales partagees, notamment grâce a l'activite de l'OIV, donne aujourd'hui encore a reflechir sur un developpement economique international appuye sur des normes partagees. Le traitement numerique et la mise a disposition du Bulletin de l'OIV fondes sur un travail universitaire realise a Dijon est un outil mis a la disposition de tous pour …
Remediation of Solutions Containing Oxyanions of Selenium by Ultrafiltration: Study of Rejection Performances with and without Chitosan Addition
2017
Among the various technical options for removing ionic contaminants from wastewaters, membrane processes and especially their coupling with polymer addition have been proven to provide worthwhile prospects for the removal of metal cations. Nevertheless, their use for the removal of anionic pollutants such as oxyanions has been little studied in the literature. In the present work, the rejection of oxyanions forms of Se(IV) and Se(VI) by tight ultrafiltration membranes was deeply investigated under various experimental conditions. This paper aims at understanding the mechanisms governing oxyanion rejection and determining the potential ways to improve performances. It is first shown that sel…
Degradation of diols and formation of ethylene glycol by different yeast species
1989
Die mikrobielle Bildung von Ethylenglykol sowie der Abbau von Diolen durch Hefestamme verschiedener Gattungen wurde im synthetischen Medium und in Traubensaft untersucht. Diole (aber nicht Diethylenglykol) wurden von Arlen wieHansenula, Candida, Pichia undRhodotorula abgebaut. Von 40 uberpruften Hefen produzierten einzelne Stamme vonZygosaccharomyces bailii, Torulopsis ernobii undKluyveromyces veronae unter aeroben Bedingungen 70 bis 210 mg/l Ethylenglykol bei Zusatz von 400 mg/l Ethanolamin zum synthetischen Medium. Ohne Ethanolamin erzeugtenZ. bailii undT. ernobii im synthetischen Medium oder Traubensaft zwischen 7 bis 30 mg/l Ethylenglykol. Die Bildung von Ethylenglykol war bei aeroben K…
Robust dynamic comfort modeling for motorcycle riding
2015
Comfort modeling is considered a prerequisite in motorcycle design, primarily to address safety concerns and to position the product on the market. However, a comprehensive methodology for comfort modeling during the earliest development phases of a motorcycle model is still missing. Anthropometrical variation is the main noise factor to consider in comfort modeling in relation to the unavoidable variability of body segments. However, comfort is a subjective concept influencing riders' choice of motorcycle model. This work is a generalization of the robust ergonomic design methodology aimed at designing products whose ergonomic performance is insensitive to anthropometrical variation. This …
Effect of ultrasound technology combined with binary mixtures of ethanol and water on antibacterial and antiviral activities of Erodium glaucophyllum…
2019
Abstract Erodium glaucophyllum is a common Mediterranean herb known for its health benefits. In this study, Erodium extracts obtained from different extraction methods (conventional vs ultrasound-assisted extraction) and extraction solvents (aqueous and hydroethanolic) were evaluated in microbiological media to determine their effects on bacteria (Salmonella enterica, Staphylococcus aureus, Listeria innocua, Bifidobacterium lactis and Lactobacillus casei) and antiviral activity (hepatitis A virus and murine norovirus). Both, the extraction method and solvent were found to be important contributing factors. Ultrasound-assisted extraction yielded the highest level of desirable Erodium-extract…
