Optimisation of the baluba east ore treatment

The Baluba east concentrator is part of the Roan Antelope Mining Corporation (RAMCO) which is a unit of the Binani Group of Companies. It treats an ore which is a mixture of sulphide and oxide copper minerals. In the flotation of mixed sulphide - oxide ores, the sulphide minerals are floated first, then followed by a sulphidisation step of the oxide minerals to effect their flotation. This test work was carried out because of a decrease in the grades and recoveries obtainable during the period of January 1998 up to around September 1998. This was so despite having an above average head grade of 1.91%Tcu. The optimum mesh of grind was found to be 65% passing 75 ìm using release analysis and theconclusions were drawn on the basis of flotation kinetics. The optimisation of reagents addition was done using a FACTORIAL DESIGN of experiments to improve the reliability of the result and Analysis of Variance(ANOVA) and the F-test were used to draw meaningful conclusions. Dosages of 120g/t collector (SIPX) and 100 g/t conditioner (NaHS) were obtained as the optimum reagent levels. The associated concentrate grade was  6.10%TCu (without a cleaning stage) at a recovery of 90.16%TCu. This adjustment in reagent consumption rates, if effected, would introduce a 10% reduction incollector consumption and a 50% reduction in conditioner consumption, which clearly indicates a significant reduction in the overall costs of reagents per tonne ore treated

FTMS: an efficient multicast scheduling algorithm for feedback-based two-stage switch

Session - NGNI02: Router Architecture & Switch DesignTwo major challenges in designing high-speed multicast switches are the expensive multicast switch fabric and the highly complicated central scheduler. While the recent load-balanced switch architecture uses simple unicast switch fabric and does not require a central scheduler, it is only good at handling unicast traffic. In this paper, we extend an existing load-balanced switch called feedback-based two-stage switch to support multicast traffic. In particular, an efficient multicast scheduling algorithm (FTMS) is designed. With FTMS, head-of-line (HOL) packet blocking at each input port is eliminated by adopting 'pointer' queues. To cut down queuing delay, packet replication is carried out at middle-stage ports. As compared with other multicast scheduling algorithms, simulation results show that our FTMS always provides the highest throughput. © 2012 IEEE.published_or_final_versio

Effectiveness of Educational Poster on Knowledge of Emergency Management of Dental Trauma - Part 2: Cluster Randomised Controlled Trial for Secondary School Students

Objective To investigate the effectiveness of educational poster on improving secondary school students' knowledge of emergency management of dental trauma. Methods A cluster randomised controlled trial was conducted. 16 schools with total 671 secondary students who can read Chinese or English were randomised into intervention (poster, 8 schools, 364 students) and control groups (8 schools, 305 students) at the school level. Baseline knowledge of dental trauma was obtained by a questionnaire. Poster containing information of dental trauma management was displayed in a classroom for 2 weeks in each school in the intervention group whereas in the control group there was no display of such posters. Students of both groups completed the same questionnarie after 2 weeks. Results Two-week display of posters improved the knowledge score by 1.25 (p-value = 0.0407) on average. Conclusion Educational poster on dental trauma management significantly improved the level of knowledge of secondary school students in Hong Kong.published_or_final_versio

On the scalability of feedback-based two-stage switch

The feedback-based two-stage switch does not require a central scheduler and can provide close to 100% throughput [3]. But the number of crosspoints required for the two stages of switch fabric is 2N2, and the average packet delay performance (even under light traffic load) is on the order of O(N) slots, where N is the switch size. To improve the performance of feedback-based two-stage switch when N is large, we adopt the Clos network for constructing a large switch from a set of smaller feedback-based switch modules. We call it a Clos-feedback switch. The potential problem of packet mis-sequencing is solved by using application-flow based load balancing. With recursive decomposition, a Clos network can degenerate into a Benes network. We show that for a Clos-feedback switch, the number of crosspoints required is reduced to 4N(2 log2N-1) and the average packet delay is cut down to O(log 2 N) slots. © 2012 IEEE.published_or_final_versio

Discontinuous Reception for Multiple-Beam Communication

This is the final version. Available from IEEE via the DOI in this recordDiscontinuous reception (DRX) techniques have successfully been proposed for energy savings in 4G radio access systems, which are deployed on legacy 2GHz spectrum bands with signal features of omni-directional propagation. In upcoming 5G systems, higher frequency spectrum bands will also be utilized. Unfortunately higher frequency bands encounter more significant path loss, thus requiring directional beamforming to aggregate the radiant signal in a certain direction. We, therefore, propose a DRX scheme for multiple beam (DRXB) communication scenarios. The proposed DRXB scheme is designed to avoid unnecessary energy-and-time-consuming beam-training procedures, which enables longer sleep periods and shorter wake-up latency. We provide an analytical model to investigate the receiver-side energy efficiency and transmission latency of the proposed scheme. Through simulations, our approach is shown to have clear performance improvements over the conventional DRX scheme where beam training is conducted in each DRX cycle.Swedish Research CouncilNational Natural Science Foundation of ChinaEuropean Union Horizon 202

Concurrent use of prescription drugs and herbal medicinal products in older adults: a systematic review protocol

Background: There has been a global increase in the use of herbal medicinal products (HMPs). About a quarter of UK adults use HMPs, bought over the counter by self-prescription and often not disclosed to healthcare professionals. Potential herb-drug interaction is a clinical concern, with older people at greater risk because of co-morbidities and slower clearance of pharmacologically active compounds. While there is a good understanding of general herbal medicine use by older people, less is known about the extent and implications of concurrent use with prescription medicines. The aim of this systematic review is to assess the prevalence, patterns, safety issues and other factors associated with concurrent prescription and herbal medicines use among older adults. Methods/design: Systematic electronic searches of MEDLINE, PsychINFO, Excerpta Medica dataBASE (EMBASE), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Allied and Complementary Medicine Database (AMED), Web of Science and Cochrane from inception till present for studies reporting the concurrent use of prescription medicines with HMPs in older adults (≥65 years). Lateral searching via related citation (PubMed) and checking reference lists of identified studies will be performed. Two reviewers will independently screen studies, extract data and appraise methodological quality using the Joanna Briggs Institute checklist for prevalence data and the Critical Appraisal Skills Programme (CASP) checklist. Qualitative and quantitative studies from all settings will be included. Non-empirical papers, in vitro experiments and animal studies will be excluded. Primary outcomes are prevalence and patterns of concurrent use, number and types of prescription and HMPs and adverse reactions reported. Secondary outcomes are disclosure of HMP use to healthcare professionals and cost of HMPs. A narrative synthesis of included studies will be performed to summarise the evidence. Discussion: This review will synthesise and critically appraise current knowledge on the concurrent use of drugs and HMPs by older adults and thus provide a better understanding of the issue. It will also identify any gaps in knowledge. By establishing safety issues associated with concurrent use, it will also inform strategies that can help practitioners to identify and manage older people at potential risk of herb-drug interactions.
