mHealth4Afrika is a collaborative research project that addresses maternal and newborn healthcare delivery, a key requirement of end-user communities in developing countries, and priority area in both the 2015 Millennium Development Goals and Post-2015 Sustainable Development Goals. Aligned with Horizon 2020 Societal Challenges, mHealth4Afrika will research and evaluate the potential impact of co-designing an open source, multilingual mHealth platform on the quality of community based maternal and newborn healthcare delivery in Southern Africa (Malawi, South Africa), East Africa (Kenya) and Horn of Africa (Ethiopia). Research and innovation actors from three European and four African countries will engage with local end-user communities (i.e. representatives of parents and local community leaders, Ministry of Health, healthcare professionals and volunteers, health oriented NGOs). Based on this User-centred Design, Living Labs, Collaborative Open Innovation based approach, the consortium will integrate and adapt Multilingual electronic health records to store patient history, associated tests and test results; Sensors to capture the results of a range of standardised tests for expectant and lactating mothers, unborn babies and infants; Analytical and visualisation tools to facilitate the interpretation and monitoring of the patient results; and Multi-lingual and multimodal mobile interfaces leveraging visualisation and speech synthesis to address literacy deficits and digitise data gathering through electronic forms. By focusing on accessibility, usability and integrated training, this will facilitate urban, rural and deep rural healthcare workers to adopt and use a comprehensive system that integrates quality community based healthcare delivery with telemedicine. The expected outcome is a multi-region proof of concept that can make a significant contribution in accelerating exploitation of mHealth across Africa.

Employers of computing graduates have high expectations of graduates in terms of soft skills, the most desirable of these being communication skills. Not only must the graduates exhibit writing skills, but they are expected to be highly proficient therein. The consequence of this expectation is not only performance pressure exerted on the graduate, but also the laying down of a challenge at the door of computing instructors to encourage and instil successfully the art of writing in the graduate. Varied and numerous initiatives have been launched in the computing discipline to address this particular challenge over the past few decades. Despite documented success on the many experiences of incorporating writing into the computing discipline, the fact is that the challenge is as relevant today as it was in the 1980s. There is sufficient evidence to suggest that agreement is yet to be reached on exactly how to integrate successfully writing skills into traditional computing curricula, thereby familiarising computing students with an essential activity of their chosen profession. Furthermore, the reporting of successful experiences tends to focus on the application of a variety of teaching strategies, is predominantly based on the experiences of instructors and is dominated by a lack of quantifiable results. This apparent lack of sufficient empirical evidence prompted a rigorous investigation into the perceived benefits of the integration of writing skills activities into a traditional intermediary level programming course. The main aim of the study is to measure the perceived benefit of each of a number of academic writing interventions, facilitated to skill students appropriately in the art of writing for the computing discipline. Each intervention is designed to support particular principles of academic writing. The ultimate outcome of the study is a survey which allows student participants to measure the perceived benefit-impact of each intervention. The qualitative and quantitative findings of this study suggest that students perceive most of the commonly used academic writing activities as beneficial in the construction of a report. What is apparent, however, is that those activities that are most frequently used by instructors are not necessarily perceived by students as being the most useful activities. © 2012 Elsevier Ltd.

This article explores current language-based research aimed at promoting scientific literacy and examines issues of language use in schools, particularly where science teaching and learning take place in teachers' and learners' second language. Literature supporting the premise that promoting reading, writing, and talking while "doing science" plays a vital role in effective teaching and learning of the subject is highlighted. A wide range of studies suggest that, whether in homogenous or language-diverse settings, science educators can make a significant contribution to both understanding science and promoting literacy.

Rivers in mediterranean regions are subject to hydrological extremes. They range from highly stable, perennial ground- or snow-fed systems to highly ephemeral, unpredictable ones in semi-arid environments. Spatial and temporal complexity inherent in these systems presents challenges for ecological status assessment and defining reference conditions, particularly as many areas have been extensively transformed through anthropogenic activities. Temporal variability driven by sequential and predictable, seasonal events of flooding and drying accentuates the need to take season and/or hydrological period into account. Intermittent streams, which are common in mediterranean regions (med-regions) and which have aquatic communities distinct from perennial streams, are often not incorporated in bioassessment and present distinct challenges. Med-regions are also known for their high biodiversity and rates of endemism, as well as large numbers of introduced species. Med-regions are expected to be among the most affected by global climate change and, in these systems, climate change is an additional driver influencing ecosystems that are already stressed. From this review it is evident that an understanding of responses of indices, metrics, and models to climate change in comparison to existing stresses, and the development of thermally specific bioassessment tools are needed for this region. © 2012 Springer Science+Business Media B.V.

Environmental flow requirements of estuaries have been ignored in the past, mostly because of the lack of long-term monitoring data or understanding of the responses to changes in freshwater inflow. In some cases, it was incorrectly assumed that the minimum flows determined for rivers would protect downstream processes and in others the omission of environmental water requirement studies for estuaries was as a result of the sectoral management of water resources or lack of applicable legislation. Three main countries have developed methods for estuaries, i.e. Australia, South Africa and the USA, from practical applications and a learning-by-doing approach. Recent methods take a holistic and adaptive standpoint and are presented as frameworks that include a number of steps and have elements of risk assessment and adaptive management. Most approaches are data rich and emphasize long-term monitoring. This review showed that, although methods are available, implementation is slow and will require strong governance structures, stakeholder participation, monitoring and feedback in an adaptive management cycle.

A method for upgrading coal fines by separating out at least some mineral components is provided. The method comprises the treatment of optionally graded coal fines with micro-algae in aqueous medium to form a slurry under conditions that permit adsorption of micro-algae onto particles of coal fines. The slurry is treated to separate a first fraction that is rich in coal fines together with adsorbed micro-algae thereon from a second fraction that has more mineral components in it than does the first fraction and processing the first fraction to recover upgraded coal fines therefrom. Contacting is preferably carried out in a manner aimed at loading the coal fines generally evenly with microalgae adsorbed thereon in an amount of from 5 to 15% by weight of coal fines. Separation may be carried out by sedimentation, cyclone separation or flotation.

A circuit structure (200) for suppressing single event transients (SETs) or glitches in digital electronic circuits is provided. The circuit structure includes a first input (100) which receives an output of a digital electronic circuit (A), a second input (100) which receives a redundant or duplicated output of the digital electronic circuit (A), and two sub-circuits (102, 106) that each receive the inputs and have one output. One of the sub-circuits is insensitive to a change in the value of one of its inputs when the inputs are in a first logic state and the other sub-circuit is insensitive to a change in the value of one of the inputs when the inputs are in a second, inverted logic state. The sub-circuit outputs are input into a two-input multiplexer (202) which has its output (204) connected to its selection port (SEL), and the sub-circuits are arranged so that the sub-circuit which is insensitive to a change in the value of one of its inputs is selected whenever the output of the multiplexer changes. The multiplexer output (204) is provided as a final output in which SETs and glitches have been suppressed.

A method of processing a carbonaceous material in the form of carbonaceous fines is provided in which the carbonaceous material is treated with micro-algae to adsorb the micro-algae onto the carbonaceous material followed by heating in a heat activating step. Such heating is effected to a temperature within the range of from that at which water starts evaporating to a temperature at which volatile components of the carbonaceous material start to volatilize. The heating is continued for a duration selected to allow chemical interaction between the micro-algae and the carbonaceous material so as to alter the chemical structure of the carbonaceous material. The carbonaceous material microalgae are preferably in the form of substantially intact cells that are still in a photosynthetically active state. Dry carbonaceous materials may be mixed with micro-algae slurry in water, or micro-algae may be added to carbonaceous material already present in water.

A method is provided for the treatment of water containing micro-algae wherein the water is contacted with carbonaceous fines to adsorb micro-algae onto particles of the carbonaceous fines. The carbonaceous fines may be coal or charcoal fines or mixtures thereof. The carbonaceous fines may be pre-treated to remove any unsuitable or valuable materials therefrom; or to produce suitable size ranges of particles for one or more purposes selected from facilitating adsorption; handling of the carbonaceous fines both before and after adsorption of the micro-algae; and separation of the carbonaceous fines with adsorbed micro-algae thereon. The method may target the beneficiation of carbonaceous fines and the carbonaceous fines together with the adsorbed microalgae thereon may be subjected to an agglomeration process for the production of agglomerates such as briquettes or pellets. The method may target the upgrading of a polluted water system in a commercial water treatment process.
