Weekly homework quizzes as formative assessment for Engineering students are a fair and effective strategy to increase learning?
2018
International audience; A strategy to apply online weekly homework quizzes as formative assessment for Engineering students was designed and tested in order to study if it increases student's learning. The strategy was to make optional weekly online quizzes not randomly generated that students may retry over and over again until to reach the correct answer, they contribute to 10% of grade but only if students get 45% or more in traditional assessment.The quizzes were applied to two different mathematics courses (Single and Multivariable Calculus) of two different Engineering degrees, each one to around 100 students and during a semester. Student's adherence was very high, nearly all student…
“Making connections” in the mathematics courses for engineers: the example of online resources for trigonometry
2018
International audience; This paper concerns the teaching of mathematics for future engineers, focusing on the theme of trigonometry. We claim that the use of trigonometry in engineering courses requires different kinds of connections: connecting different domains, different concepts, frames and registers. We use here the concept of connectivity, developed in the frame of e-textbooks analysis, to analyse online courses for future engineers in France. We evidence that these courses propose some connections; but their connectivity is not developed enough to meet the requirements of engineering courses.
Student Partners in Task Design in a computer medium to promote Foundation students' learning of mathematics
2018
International audience; A team consisting of three mathematics education teacher-researchers, four former Foundation students (called Student Partners, SPs), and two analytic assistants worked together to produce mathematical tasks in a computer medium for the mathematical learning of current Foundation students (FSs). We have explored the collaboration between the SPs and researchers, the processes and outcomes of task design, and the contribution of the collaboration to tutorial teaching of FSs. We seek insight into the learning of all concerned of mathematics, mathematics teaching, task design and personal-professional development. The project is ongoing. Here we introduce the project an…
Synthesis and Characterization of Palladium Nanoparticle/Polypyrrole Composites
2008
In this work, a simple non-template one-step method for the synthesis of 2.0−2.5 nm palladium nanoparticles encapsulated into a polypyrrole shell via direct redox reaction between palladium(II) acetate and pyrrole in acetonitrile medium is described. Palladium nanoparticles are found to be able to self-organize into spherical Pd/PPy composites. The size of the Pd/PPy composite particles and Pd content in the composite depend strongly on the concentration of the palladium salt component. The combination of elemental CHNS and thermogravimetric (TGA) analysis was used to determine a high (∼40 wt %) content of palladium, which is in a good agreement with EDX data. The process of Pd/PPy composit…
Total petroleum hydrocarbons (TPH) determination in surfactant stabilized marine water emulsions
2022
Bilge waters are wastewaters produced on boats during navigation and usually contain hydrocarbons and oils. They cannot be released into the sea if not below certain hydrocarbon concentration limits set by current legislation. Surfactants are often used to improve the solubility of petroleum hydrocarbons in water and in this work, the analytical approach proposed is suitable to determine accurately the concentration of hydrocarbons in surfactant-rich waters, as found in bilge water or similar wastewater. The method relies on the surfactant precipitation by addition of potassium and calcium salts, which also promote TPH extraction through a “salting out” effect. This allows for an accurate d…
An open-source instrumentation package for intensive soil hydraulic characterization
2020
International audience; We present a new open-source and modular instrumentation package composed of up to ten automatic in- filtrometers connected to data acquisition systems for automatic recording of multiple infiltration experiments. The infiltrometers are equipped with differential transducers to monitor water level changes in a Mariotte re- servoir, and, in turn, to quantify water infiltration rates. The data acquisition systems consist of low-cost components and operate on the open-source microcontroller platform Arduino. The devices were tested both in the laboratory and on different urban and agricultural soils in France and India. More specifically, we tested three procedures to t…
Automatic Extraction of Semantic Roles in Support Verb Constructions
2021
This paper deals with paraphrastic relations in Italian. In the following sentences: (a) Max strappò delle lacrime a Sara 'Max moved Sara to tears' and (b) Max fece piangere Sara 'Max made Sara cry', the verbs differ syntactically and semantically. Strappare 'tear/rip/wring' is transitive, fare ‘have/make’ is a causative, and piangere 'cry' is intransitive. Despite this, a translation of (a) as (b) is legitimate and therefore (a) is a paraphrase of (b). In theoretical linguistics this raises an issue concerning the relationship between strappare and fare/piangere in Italian, and that in English between move and make. In computational linguistics, can such paraphrases be obtained automatical…
Programmatūras dzīves cikla trasējamība, veicot ALM rīku integrāciju
2017
Mūsdienās tiek izstrādātas jaunas un papildinātas esošas programmatūras un informāciju sistēmas, kuras tiek veidotas arvien komplicētākas un apjomīgākas, kā rezultātā ar to saistītais informācijas apjoms ievērojami pieaug. Šādu sistēmu dzīves ciklu pārvaldība nav viegls uzdevums, jo ne tikai tās informācijas apjoms ir liels, bet šo informāciju var ietekmēt katra no iesaistītajām personām, kurai katrai var nedaudz atšķirties izstrādājamā risinājuma nolūks un skata punkts uz to. Bakalaura darba “PROGRAMMATŪRAS DZĪVES CIKLA TRASĒJAMĪBA, VEICOT ALM RĪKU INTEGRĀCIJU” mērķis ir izpētīt un rast integrētu risinājumu programmatūras dzīves cikla artefaktu informācijas atsekošanai un pārraudzībai no p…
[The role of the anesthesiologist in secondary hyperparathyroidism].
2010
In the last years the increasing of diabetes and hypertension has produced a considerable increase of patients with chronic renal failure; secondary hyperparathyroidism is one of the major complications. The resection of hyperfunctioning parathyroid tissue is the ultimate goal of the treatment. The preoperative examination by the anesthetist is the starting-point of the treatment. The anesthetist programs hemodialysis, the correction of fluid and electrolyte abnormalities and of the anaemia. In the operating room the anesthetist is involved in the careful monitoring of liquid infusion and anesthesiological procedure. The intraoperative parathyroid hormone (PTH) assay is an essential tool be…
La intervenció de la/treballador/a social sanitari a la Comunitat Valenciana
2012
The purpose of this document is to provide both, professionals and citizens, with information about the procedures and processes of intervention developed by social workers within the different health institutions of the Community of Valencia. It is important to identify the specificity of Social Work in the Health Care System in order to consolidate Professional Identity from the homogeneity in the processes and procedures of intervention and the identification of the duties carried out by these professionals in the different health institutions/services of the Community of Valencia.
