Surface modification of luminescent lanthanide phosphate nanorods with cationic "Quat-primer" polymers.

2011

"Quat-primer" polymers bearing cationic groups were investigated as a surface modifier for Tb-doped cerium phosphate green-emitting fluorescent nanorods (NRs). The NRs were synthesized by a microwave process without using any complex agents or ligands and were characterized with different analytical tools such as X-ray diffraction, transmission electron microscopy, and fluorescence spectroscopy. Poly(ethyleneimine) partially quarternized with glycidyltrimethylammonium chloride was synthesized separately and characterized in detail. (1)H and (13)C NMR spectroscopic studies revealed that the quaternary ammonium group was covalently attached to the polymer. UV-vis spectroscopy was used to exam…

Epistemic and didactic values of the demonstrative process in different cultures: a case study in Geometry with Chinese and Italian students

2011

This paper presents same key findings of the research project conducted by G.R.I.M. of Palermo on the approaches to justification and proof in Geometry by investigating how Chinese and Italian teachers and students taught particular geometrical topics refereed to different epistemic and didactic values related to own culture. It was found that Chinese teachers and students emphasized justification of the proof by a stressed visual verification based on some metarules linked with the structure of their own written language and defined as historical Chinese modus operandi in the Jiuzhang Suanshu. The Italians paid close attention to mathematical proof by a hypoxemic deductive system defined on the Euclide’ Elements. The geometrical problem discussed on the paper was defined and presented as “one problem multiple solution problems” and “one problem multiple changes”. Important aspect of the case study discussed in the paper focus on the mediation of knowledge between Chinese and Italian students involved in multicultural class. According to us these kind of activities can establish possibilities for the students to confront their self with different cultural social and educational prospective of knowledge discovering the power of mathematics as tool of negotiation in multicultural class?Settore MAT/04 - Matematiche Complementari

Innovative fully robotic 4-arm Ivor Lewis esophagectomy for esophageal cancer (RAMIE4).

2019

Nowadays robotic surgery is established for abdominal and thoracic surgery. It has been shown that complex procedures are feasible using robotic systems, e.g., da Vinci Xi, with a huge benefit in precision. Different techniques for esophageal cancer surgery are reported; however, only a few robotic and partial robotic procedures are described. Therefore, a fully robotic (abdominal and thoracic) Ivor Lewis esophageal resection using four robotic arms-RAMIE4-the standard technique used for lower esophageal cancer, is presented in this paper. The technique shown in the video was performed successfully in 100 cases in 24 months. The reconstruction is performed with a gastric conduit pull-up and…

Abstract Background: The association of attention-deficit/hyperactivity disorder (ADHD) and tic disorder (TD) is frequent and clinically important. Very few and inconclusive attempts have been made to clarify if and how the combination of ADHD+TD runs in families. Aim: To determine the first time in a large-scale ADHD sample whether ADHD+TD increases the risk of ADHD+TD in siblings and, also the first time, if this is independent of their psychopathological vulnerability in general. Methods: The study is based on the International Multicenter ADHD Genetics (IMAGE) study. The present sub-sample of 2815 individuals included ADHD-index patients with co-existing TD (ADHD+TD, n=262) and without …

[Choosing a quality-of-life questionnaire].

2006

International audience; Define the objective of the questionnaire: Discrimination: do you want a questionnaire to enable you to describe the quality of life of patients or to compare the quality of life between groups of patients, for example, to determine who has improved and who has gotten worse? Assessment: do you want a questionnaire to help you measure changes over time (improvement or aggravation) in your patients? Determine the properties of instruments necessary for this objective: If the objective is discrimination, analyze: construct validity, reliability. If the objective is assessment, analyze construct validity, sensitivity to changes. Choose the general category of questionnai…

Occupational health disparities among U.S. long-haul truck drivers: the influence of work organization and sleep on cardiovascular and metabolic dise…

2018

Objective The organization of work has undergone vast transformations over the past four decades in the United States and has had profound impacts on worker health and wellbeing. The profession of commercial truck driving is one of the best examples. Particularly for long-haul truck drivers, changes in work organization have led to disproportionately poor physiological, psychological, and sleep health outcomes. Methods The present study examined disparities in cardiometabolic disease risk among long-haul truck drivers and the general population, and the influence of work organization and sleep in generating these outcomes. Researchers collected survey data from 260 drivers, and blood assay …

Predicting accelerometer-based physical activity in physical education and total physical activity: The Self-determination Theory approach

2019

The present study tested the motivational model of physical education (PE) including needs for competence, autonomy, social relatedness, intrinsic and extrinsic motivation, in-class moderate to vigorous physical activity (MVPA), and total MVPA. Participants were 490 (264 girls, 226 boys) Finnish elementary school students. The data were collected using accelerometers and questionnaires for a seven-day period during the fall semester 2017. The key findings were that 1) social relatedness associated with total MVPA via in-class MVPA in girls, whereas competence was linked to in-class MVPA through extrinsic motivation in boys, 2) competence was positively linked to extrinsic motivation in a si…
