Hybrid RF-FSO Transceiver for Adaptive Real-time Signal Reception and Distribution Dr Sunday Ekpo, Dr Muhammed Ijaz, Opeyemi Oguntodu In recent years, there has been tremendous advancement and growth in information and communications technology. The increase in the use of video-conferencing, high speed Internet, aircraft monitoring, disaster management etc., has seen bandwidth and capacity requirements increasing exponentially. The aim of this research is the production of an integrated multichannel adaptive and reconfigurable hybrid RF-free space transceiver for real-time signal capturing and distribution. This research work will be targeting 5G frequency band. However, various simulations will be carried out across the frequency band (C, X, Ku. Ka-band) The aims include: 1. Design of RF and FSO transmitters and receivers (Transceiver) 2. Modelling of RF and FSO transmitters and receivers (Transceiver) 3. Simulation of RF and FSO transmitters and receivers (Transceiver) 4. Development and prototyping (Fabrication) of an integrated multichannel adaptive and reconfigurable Hybrid RF-FSO transceiver. As this is a qualitative research, various software and hardware are used for data collection. MatLab software is used for generating various signals; Advanced Design System (ADS) will be used to design the RF transceiver. Optism will be used for the FSO transceiver. Other software used for this research include: Vector Analyser, SystemVue and Hardware include Integrated RF/microwave-Fibre communication system testbed. This research will ensure reliable and sustainable real-time acquisition, processing, and transmission of information. Applications where this research will be used include, aircraft monitoring; capability-based satellite payload implementation; seamless space-earth connectivity due to high data rate and availability of links; disaster management; high-definition video imagery. This research work will change lives as it helps to ease and transform the way information is passed from one media to the other How to evaluate dancers’ performance? The validation of a jump mat to be used in the field Bárbara Pessali-Marques, Gladys Onambele-Pearson, Adrian Burden, Islay McEwan. Jump capability is crucial for dancers, however, when compared to physically active control participants, they do not jump significantly higher. Jump height can be increased with training, although there is evidence to suggest that dancers do not undertake sufficient supplementary training, or that the training may be ineffective. For good jump training results, jump height should be monitored. Force platforms and 3D-analysis are considered to be the gold standard for jump height measurements, however, they are expensive and their acquisition is not often possible for dance companies. An alternative is the jump mat that is cheaper, lighter, and considered to be a reliable method(5), despite accuracy levels being questionable. The aim of this study was to compare data from jump mat with that from force platform and 3Danalysis in order to validate and calculate its reliability. One participant performed 12 countermovement jumps in each situation: jump mat+3D-analysis; force platform+3D-analysis, and; jump mat+force platform+3D-analysis. The jump mat intra and inter reliability between 12 countermovement jumps was found to be very good (CV=2.93% and CV=3.33%, respectively). The correlation between jump mat and force plate was r 2 =0.76 and the equation to predict force plate height from jump mat height was found to be y=1.6664x-36.041. The jump mat overestimate the jump height compared to the 3D-analyses in 12.99±0.64cm, (Bland-Altman analysis 95% limits of agreement ranging from 11.72 to 14.26cm). Jump mat was found to be reliable and valid for field based monitoring of jump height. This may change dancers’ lives, as better performance could lead to a more successful career.
“She’ll be like ‘oh, I’m a psycho’ and it’s not, she doesn’t mean it like that.” The Language and Labelling Used by University Students When Discussing Mental Health Judith Rodwell Research around mental health labelling has focused mainly on stigma and the negative implications of attaching a label to a mental health issue, although there has been little investigation into how attitudes towards mental health and the use of mental health labels are developed through individual social influences and experiences. The present research aimed to explore University students’ understanding of mental health issues, mental health labels, and their attitudes towards these concepts within a focus group setting. Five participants discussed social aspects of their childhoods that they considered had affected their attitudes towards mental health and labelling. A thematic analysis produced three major themes; ‘the language and context of labelling’ where participants explored their own use of labels in everyday situations, ‘stereotypes and social stigma’ outlining the lack of understanding of the impact of mental health labels, and ‘personal experiences’ where participants discussed their own encounters with mental health issues. This is a pilot study and these themes will inform future research in the area. Uncovering the leading influential factors that form our initial opinions and attitudes towards mental health and its associated labels is valuable for further developing anti-stigma initiatives, improving the mental health literacy of the general population, and in turn, changing the lives of those who experience mental health stigma. Antimicrobial activity of essential oils and biocides against Candida albicans Elisa Serra, Joanna Verran, Araida Hidalgo-Bastida, Sladjana Malic Introduction and Aims: Oral candidosis is an oral infection caused mainly by C. albicans. Management of this infection is limited due to the low number of antifungal drugs, the toxicity of the available compounds and the emergence of antifungal resistance. The aims of this study are i) the evaluation of the antifungal activity of 15 essential oils and two biocides (chlorhexidine and triclosan) against C. albicans in a planktonic and biofilm growth mode, ii) the evaluation of the synergy blends and iii) the test of the cytotoxicity. Methods: To determine the Minimum Inhibitory Concentrations (MICs) and the Minimal Biofilm Eradication Concentrations (MBECs) C. albicans is exposed to a range of antimicrobial concentrations. The synergistic activity is evaluated by the Fractional Inhibitory Concentration (FIC) Index, while the cytotoxicity is assessed on murine fibroblasts by the Half Maximal Inhibitory Concentrations (ICs50). Results: All the compounds tested have an anti-candidal potential in the planktonic form, while biofilms show a noticeable increase resistance, with only five essential oils active. The check board method does not show a synergistic effect, although an additive relation is found. Finally, the cytotoxicity screening reveals that the ICs50 are lower than the corresponding MICs. Conclusions: Susceptibility of C. albicans against the antimicrobials tested is apparent, despite an enhanced biofilm resistance being evident. Even if a synergistic activity is not detected, the additive relation allows obtaining the same level of C. albicans inhibition using lower concentrations than the MICs. However, the compounds inhibit fibroblast proliferation.
