Using IT to Improve the Academic Success of College Students with Learning Disabilities

Disponible en français dans EDUQ.info sous le titre "Utiliser les technologies de l'information et de la communication afin d'améliorer la réussite collégiale des étudiants ayant des troubles d'apprentissage"This article explores the role that IT can play in improving the academic success of learning-disabled college students. The authors discuss the IT required by students dealing with learning disabilities, as well as suggestions for improvement on IT use voiced by these students and other stakeholders (including those providing special-needs services). They conclude with recommendations on how to ensure that IT use in colleges promotes academic success

Drivers of reef shark abundance and biomass in the Solomon Islands

Remote island nations face a number of challenges in addressing concerns about shark population status, including access to rigorously collected data and resources to manage fisheries. At present, very little data are available on shark populations in the Solomon Islands and scientific surveys to document shark and ray diversity and distribution have not been completed. We aimed to provide a baseline of the relative abundance and diversity of reef sharks and rays and assess the major drivers of reef shark abundance/biomass in the Western Province of the Solomon Islands using stereo baited remote underwater video. On average reef sharks were more abundant than in surrounding countries such as Fiji and Indonesia, yet below that of remote islands without historical fishing pressure, suggesting populations are relatively healthy but not pristine. We also assessed the influence of location, habitat type/complexity, depth and prey biomass on reef shark abundance and biomass. Location was the most important factor driving reef shark abundance and biomass with two times the abundance and a 43% greater biomass of reef sharks in the more remote locations, suggesting fishing may be impacting sharks in some areas. Our results give a much needed baseline and suggest that reef shark populations are still relatively unexploited, providing an opportunity for improved management of sharks and rays in the Solomon Islands

Three dimensional distributions of arsenic and platinum within NiSi contact and gate of an n-type transistor

Atom probe tomography was used to study the redistribution of platinum and arsenic atoms after Ni(Pt) silicidation of As-doped polycrystalline Si. These measurements were performed on a field-effect transistor and compared with those obtained in unpatterned region submitted to the same process. These results suggest that Pt and As redistribution during silicide formation is only marginally influenced by the confinement in microelectronic devices. On the contrary, there is a clear difference with the redistribution reported in the literature for the blanket wafers. Selective etching used to remove the non-reacted Ni(Pt) film after the first rapid heat treatment may induce this difference. © 2011 American Institute of Physics

Centrifugal spreader eco-evaluation method: Sulky Econov example

International audienceThe study shows how it is possible to evaluate spreader performances when it is really used in the field. The study deals with the new Econov section control evaluation. It shows first the followed methodology and its three steps, from continuous data acquisition of spreader parameter states to spread pattern characterization, and finally distributed rates into the field. Obtained maps results are given as well for spreader parameter states as for final obtained field rates. Performed in many cases of field shape, fertilizer types, with section control or not, the study gives some quantified results about induced spreading defaults and also on benefits to use section control devices. It particularly highlights the first order importance of field shape and the regularity of spaces between tramlines importance, firstly to obtain the desired rate (global gain) and secondly to minimize fertilizer rate dispersion and maximize crops yield and quality. In a second level, fertilizer performance is also presented, mainly by the dispersion reduction it allows when transverse curves are triangular. In a more precise analyze, benefits to use section control is also evaluated regarding the position in the field (main field application vs boarder application)

Atom probe tomography of SRAM transistors: Specimen preparation methods and analysis

Different FIB-based sample preparation methods for atom probe analysis of transistors have been proposed and discussed. A special procedure, involving device deprocessing, has been used to analyze by APT a sub-30 nm transistor extracted from a SRAM device. The analysis provides three dimensional compositions of Ni-silicide contact, metal gate and high-k oxide of the transistor gate. © 2013 Elsevier B.V. All rights reserved
