Chemistry of the Oxidant, Ferrate, Its Interaction With Specific Organics Found in Waste Water

It became obvious during this investigation that while much work has been done with ferrate (VI) chemistry, discrepancies existed in the literature and very little attention had been given possible engineering uses. This work attempted to fulfill these two needs in an exploratory manner. The preparative techniques were reviewed and mechanical improvements made in one which allowed improved yields. Essentially what was done was to enlarge and improve the filtering technique of the product and use cooler temperatures throughout the preparation. This greatly shortened the time required. Then it was learned that the addition of ethyl alcohol to the final filtrate, after product separation, produced more ferrate (VI) but of lower purity. Qualitative studies showed however, that for most situations high purity was not required. The procedure developed resulted in doubled yields and reduced time of preparation

Challenges in Improving Information Security Practice in Australian General

The status of information security in Australian medical general practice is discussed together with a review of the challenges facing small practices that often lack the technical knowledge and skill to secure patient information by themselves. It is proposed that an information security governance framework is required to assist practices in identifying weaknesses and gaps and then to plan and implement how to overcome their shortcomings through policies, training and changes to processes and management structure

An Information Security Governance Framework for Australian Primary Care Health Providers

The competitive nature of business and society means that the protection of information, and governance of the information security function, is increasingly important. This paper introduces the notion of a governance framework for information security for health providers. It refines the idea of an IT Balanced Scorecard into a scorecard process for use in governing information security for primary care health providers, where IT and security skills may be limited. The approach amends and justifies the four main elements of the scorecard process. The existence of a governance framework specifically tailored for the needs of primary care practice is a critical success factor if such organizations are to move to a robust level of information security. The challenge is twofold. Firstly, measures for governance need to be understandable to the target audience using the framework. Secondly, the number of measures needs to be controllable otherwise the process will become unviable and unused. This research synthesizes existing models and industry standards to formulate a new governance process that meets these two important criteria. The contribution of this research is in the refinement of governance metrics to make them useful to healthcare providers, specifically in relation to IT and new information communication technologies

Phases of granular segregation in a binary mixture

We present results from an extensive experimental investigation into granular segregation of a shallow binary mixture in which particles are driven by frictional interactions with the surface of a vibrating horizontal tray. Three distinct phases of the mixture are established viz; binary gas (unsegregated), segregation liquid and segregation crystal. Their ranges of existence are mapped out as a function of the system's primary control parameters using a number of measures based on Voronoi tessellation. We study the associated transitions and show that segregation can be suppressed is the total filling fraction of the granular layer, $C$, is decreased below a critical value, $C_{c}$, or if the dimensionless acceleration of the driving, $\gamma$, is increased above a value $\gamma_{c}$.Comment: 12 pages, 12 figures, submitted to Phys.

Amino acids in samples of surface sea water

Both paper and ion exchange chromatographic techniques have been used to identify and make a partial quantitative estimate of amino acids in surface water samples collected in four subtropical regions. The most abundant of the 18 amino acids identified were aspartic acid, threonine, serine, glutamic acid, alanine, valine, isoleucine, and leucine. In general, basic amino acids, possibly except for lysine, seem to be in low concentration. The amino acid composition of hydrolysates of proteinaceous material in sea water varies in the samples. These differences may be important in the ecology of marine organisms

Student attitudes towards technology and their preferences for learning tools/devices at two universities in the UAE

© Journal of information Technology Education Research 2018. Aim/Purpose The purpose of this study was to survey student opinions about technology in order to best implement and utilize technology in the classroom. In this paper, technology refers to \u27digital technology\u27. The aims of this study were to: (1) examine student attitudes towards technology in regards to enjoyment and per-ceived usefulness; (2) investigate what tools and devices students enjoyed and preferred to use for learning; (3) examine whether students preferred learning with books and paper instead of technological devices (e.g. laptops, tablets, smartphones); and (4) investigate whether student opinions about digital tech-nology and preferred learning tools differ between two universities (based on their level of technology implementation) and between two programs (Founda-tion Studies and General Studies). Background Previous studies have investigated student device choice, however, fewer studies have looked specifically at which tools and devices students choose for certain academic tasks, and how these preferences may vary according to the level of digital technology integration between two different universities. Methodology In this study, a mix of quantitative and qualitative data was gathered from 1102 participants across two universities in the United Arab Emirates from an Eng-lish-language Foundation Studies program and a first-year General Studies pro-gram. A questionnaire (containing closed-ended and open-ended questions) was followed by three focus-group interviews (n=4,3,2). ANOVA and t-Tests were used to test for statistically significant differences in the survey data, and qualita-tive survey and interview data were analyzed for recurring themes. Contribution This study aims to provide a more comprehensive account of the learning tools (including books/paper, laptops, tablets, and phones) students prefer to use to complete specific academic tasks within a university context. This study also seeks to evaluate student attitudes towards using digital technology for learning, in order to best implement and utilize technology in the context of higher edu-cation institutions in the Middle East and around the world. Findings Findings suggest that participants enjoy learning how to use new technology, believe it improves learning, and prepares them for future jobs. Books/paper were the most preferred resources for learning, followed closely by laptops, while tablets and smartphones were much less preferred for specific educational tasks. The data also revealed that respondents preferred learning through a combination of traditional resources (e.g. books, paper) and digital technologi-cal tools (e.g. laptops, tablets). Recommendations for Practitioners These findings can be used to recommend to educators and higher education administrators the importance of adopting learning outcomes related to digital literacy in the classroom, to not only help students become more effective learners, but also more skilled professionals in their working lives. Additionally, classroom practices that incorporate both traditional tools and newer techno-logical tools for learning might be most effective because they provide flexibility to find the best learning tool(s) for the task. Recommendations for Researchers Participants preferred books and paper for learning. One reason was that paper helped them remember information better. More research needs to be done on the learning benefits of using more tactile mediums, such as paper for reading and writing. Impact on Society The findings from this study suggest that some learners may benefit more from the use of digital technology than others. Institutions and organizations need to provide flexibility when it comes to technology implementation for both stu-dents and faculty. This flexibility can accommodate different learning styles and preferences and not isolate individuals in the classroom or workplace who may be slower to adapt to new technologies. Future Research Future research is needed to investigate student attitudes towards digital tech-nology at higher education institutions in other parts of the world. In addition, this study focused mostly on student perceptions of learning tools and devices in the classroom. More research needs to be done on the impact technology has on learning per se - specifically how certain tools may help learners more effec-tively complete different educational tasks
