Abstract
The production of waste pollutants has increased in recent decades at an impressive rate. These pollutants pose a threat to life on our planet, so it is increasingly important to process them correctly. Fortunately, today it is possible to obtain profit through the reuse and recycling of most of these residues, in particular, of vegetable oil, which is especially interesting due to the potential of transforming it into biodiesel. However, this process does present some constraints, mainly related to the operating costs associated with its collection. This paper proposes a new platform that aims to simplify the bureaucracy of the process and optimize the collection routes, thus maximizing the potential profit to be obtained from this business.

Abstract
Web accessibility is becoming a current topic in social and scientific discussions. With the advances in technology, a need for access to all Web resources is becoming more and more recurrent due to the several advantages that the Web brings to those with some sort of disability, allowing them accessing and integrating in society. With this document we aim to present indicators regarding the lower accessibility levels of the Portuguese teaching institutions websites. A set of background and theoretical considerations is made alongside the article, as well as the results of an accessibility evaluation made to the Portuguese secondary schools websites using a specialized software tool and according to WCAG 2.0. The present document also contains a proposal for a model that aims on improving Web accessibility Levels in Portugal by fostering the creation of relations and group activities between the actors that, in our opinion, are those with the most relevance in the Web content accessibility issue.

Abstract
This article describes an application proposal since the analysis till the development of a software, which presents itself as a solution to the existent management problem in the Electronics Store in the Engineering Department of University of Tras-os-Montes and Alto Douro. The study as followed a development methodology intrinsic to the problem and to all the features associated to management systems, with the main purpose to obtain a suitable solution by means of Information Technologies capable to support the users in the management of all services and resources of the store in a way completely integrated with the information systems that are more relevant to teaching activity. The solution was developed using Web technologies, enabling an optimized channel for accessing and managing all services and products provided by the store, increasing their efficiency, organization and ability to respond to requests made by all users.

Abstract
Higher education institutions (HEI) and students are highly dependent of information systems, implemented as web applications. Students must be able to access this applications, thought accessible web interfaces, in order to perform their academic activities. This paper presents an overview of a typical set of web applications used by students and the main concerns regarding accessibility compliance. The analysis was conducted using the systems at the University of Trás-os-Montes e Alto Douro. © 2013 Springer-Verlag Berlin Heidelberg.

Abstract
The XXI Century society has developed a drive for Information and the Web, as one of the extremely important technologies of our times, represents the main channel to access it. As a result of this, one can perceive that the Web, and the inherent websites, must be accessible to all, in order to maintain the imperative social equality. Despite the legal requirements to the Portuguese Web content accessibility levels, in effect since 1999, the existent studies that focused on assessing those same levels of accessibility reported that the Portuguese websites, in their majority, were not compliant with the existent standards. In mid-2007 we started, within our research group and in partnership with both UMIC - Knowledge Society Agency and APDSI - Association for the Promotion and Development of the Information Society, a Web accessibility barometer. The goal of this barometer has been assessing the accessibility levels of the Portuguese websites, creating recommendations - for both the organizations and the civil society - towards the improvement of the referred websites, and publicly presenting the achieved results. One of the Portuguese enterprises that is adopting the accessibility standards into its public procurement platform anoGov is ANO. This company established a research project alongside UTAD University in order to achieve technical know-how and good practices that allowed them to develop accessible and usable Web content. © 2013 Springer-Verlag Berlin Heidelberg.

Abstract
This paper presents a proposal for the management, mentoring and training activities for employees of an organization. The training activities normally take place indoors; however, the nomadic life of some employees often makes difficult their training. Thus, the proposal takes into account the internal trainees and those who for various circumstances may not do so presentially. The use of heterogeneous mobile devices was further concerns the design proposal, since it is not always possible that all learners have the same type of platform, making it even more complicated if the organization allow BYOD. This proposal includes the development of two server applications, one located inside the organization and the other located in the cloud. The proposed solution will enable mobile interaction between the devices, the internal server and the server located in the cloud.
