DESIGNING AN EDNA ASSAY FOR RIVER OTTER (LONTRA CANADENSIS) DETECTION IN STREAMS

Environmental DNA (eDNA) is a highly promising field of survey science that hasn’t been fully explored on mammalian species. The river otter species (Lontra canadensis), is a prime candidate for testing eDNA’s uses and limitations with mammals. An eDNA primer was therefore  designed that fully amplifies river otter DNA, but does not amplify any other species, including closely related ones . Candidate primer sets were generated using the computer programs BioEdit 7.2.5 , Mega6 , eprimer3 , and Life Technologies. Once primer set possibilities were identified, those with the most base pair differences in non-target species were selected and purchased. Then, using qPCR techniques, two primer sets (OTTER_2 and OTTER_3) were tested against thirteen target DNA samples and seventeen varying non-targets. The primers were effective in amplifying all target species, but also amplified many non-target species in later PCR cycles. Hence, an internal probe was additionally designed to add specificity for the OTTER_2 primer set. The probe was not as effective as decreasing non-target amplification as hypothesized, which lead to the prediction that the samples themselves may have been contaminated with river otter DNA. To test this, the non-targets that amplified despite the additional probe were re-extracted and run through qPCR with the OTTER_2 primer set. Any amplified results will be sequenced. If sequenced results produces otter DNA, the samples are contaminated and not indicative of assay specificity, if it produces non-target DNA, then the assay must be redesigned. It is the eventual goal to use this assay in management scenarios

Biquad Based on a Generalized Divider Structure

The paper deals with the biquad based on a generalized divider structure. This principle can be considered as an effective way of universal filter and equalizers synthesis, which easily realizes any general transfer function. An attention is devoted to the derivation of optimum design conditions. As shown, these conditions strongly depend on the amplifier type used. The results obtained are illustrated by some design examples

Stacked Convolutional and Recurrent Neural Networks for Music Emotion Recognition

This paper studies the emotion recognition from musical tracks in the 2-dimensional valence-arousal (V-A) emotional space. We propose a method based on convolutional (CNN) and recurrent neural networks (RNN), having significantly fewer parameters compared with the state-of-the-art method for the same task. We utilize one CNN layer followed by two branches of RNNs trained separately for arousal and valence. The method was evaluated using the 'MediaEval2015 emotion in music' dataset. We achieved an RMSE of 0.202 for arousal and 0.268 for valence, which is the best result reported on this dataset.Comment: Accepted for Sound and Music Computing (SMC 2017

Reflective practice in portfolio development: Perceptions of fourth-year nursing students at the University of the Western Cape

Magister Curationis - MCurBackground: At the School of Nursing (SoN) of the University of the Western Cape (UWC) students (usually across all levels) carry out reflective practice when they compile a portfolio of evidence (PoE) to be submitted at the end of each semester. This contributes to their formative assessment. The PoE is a great assessment tool, although for various reasons it is often completed late by the students. Registered fourth-year nursing students were the sample population, because they have been actively involved in reflective practice through the process of compiling a PoE towards the end of every semester, and they have been doing this since their first year. In order to accomplish safe clinical judgements, nurses must be encouraged to become analytical and critical thinkers. Development of a PoE while reflecting on their clinical experiences is one of the strategies that can be used to enhance analytical and critical thinking among the students. Also, these learners carried out reflective practice, mostly on clinical activities that they were exposed to, and the PoE requirements and evidence are mostly clinically inclined (for example, incidents that they encountered, record of attendance at the clinical facilities). How the students perceive this process is important if they are to be encouraged to do reflective practice. Compilation of a PoE at an SoN of a university in the Western Cape requires and comprises a record of evidence that the learners put together and thereafter reflect upon. Objective: To describe the perceptions of fourth-year nursing students regarding reflective practice when compiling their PoE. Method: A qualitative design was used to explore the perceptions of registered fourth-year nursing students regarding their reflective practice when compiling their PoE. A purposive sampling method was employed, and three focus group discussion (FGD) sessions were held consisting of 6-8 participants per group. Data saturation was achieved at the third session. Tesch‟s method of data analysis was used. Ethical considerations were employed through the informed consent process, confidentiality, dependability, credibility of participants and appropriate handling and storage of the collected data and the tape recorder. Results: The results of this study show that through reflection the learners gained experience and professionalism from incidents that occurred and activities expected of them, mainly at the hospitals and classroom. Participants reflected on both good and bad experiences, and saw them as challenges preparing them for the future, bearing in mind that they had just about a month until commencing their Community Service Programme. For some of the participants the compilation of the PoE was a great teaching and learning strategy, as learning gaps were identified and it helped them improve their record-keeping and organisational skills

Using several data sources for offshore wind resource assessment.

The knowledge of wind resource is essential to the sitting of a wind farm. This is crucial especially in coastal areas where installation of windmills is more costly than onshore. More accurate estimation of the resource is necessary to preserve the confidence of investors and reduce the cost of production. Nowadays, the resource is evaluated by interpolation of discrete measurements but offshore measurements are rare and very costly (750,000 euros for an offshore mast) [1]. In addition, coastal wind distribution is characterised by large spatial variations, which are not represented by local measurements. Several studies demonstrated the potentials of using satellite images to map the wind field at sea surface. However, [3] and [4] show the limitations of the use of only one source of data. These limitations are caused by either low spatial resolution of data or localisation far away from coast or too low numbers of measurements for a given site. One solution is to merge al! available data to get a more accurate estimation of wind resource [4]. Satellite data have different spatial resolutions, localisations and temporal sampling. These differences impose constraints to the fusion method. In order to work out a data fusion method and evaluate it, it is necessary to study these constraints and their impacts. This paper gives an overview of various available offshore wind data. They are obtained by an appropriate processing of observations of the sea surface performed by spaceborne radars. We study the characteristics of the various data sets, namely, spatial and temporal coverage, spatial and temporal sampling, data support and accuracy. Finally, we discuss the design of a fusion algorithm

Satellite data for high resolution offshore wind resource mapping: A data fusion approach

International audienceWind resource mapping needs accurate high spatial and temporal resolutions wind measurements. Offshore, satellite data are an accurate and economic way to access wind measurements. Previous studies showed the capabilities of some remote sensing instruments to measure the wind. Synthetic aperture radars (SAR) have a high spatial resolution but are associated to a low temporal repetitiveness, preventing resource assessment reliability due to the small number of samples. Scatterometers have a sufficient temporal repetitiveness for assessment reliability but have a low spatial resolution (25 km). In this paper we apply a data fusion method to these different datasets. The fusion of scatterometer and SAR data sets results on a synthetic data set having the high spatial resolution of SAR measurements and the temporal repetitiveness of scatterometer measurements. This synthetic data set, having high spatial resolution, can be used to assess the resource at a high spatial resolution. It meets the requirements of the computation of wind statistics

Development of amperometric biosensor with cyclopentadienylruthenium (II) thiolato schiff base self-assembled monolayer (SAM) on gold

Magister Scientiae - MScA novel cyclopentadienylruthenium(II) thiolato Schiff base, [Ru(SC6H4NC(H)C6H4OCH2CH2SMe)(η5-C2H5]2 was synthesized and deposited as a selfassembled monolayer (SAM) on a gold electrode. Effective electronic communication between the Ru(II) centers and the gold electrode was established by electrostatically cycling the Shiff base-doped gold electrode in 0.1 M NaOH from -200 mV to +600 mV. The SAMmodified gold electrode (Au/SAM) exhibited quasi-reversible electrochemistry. The integrity of this electro-catalytic SAM, with respect to its ability to block and electro-catalyze certain Faradaic processes, was interrogated using Cyclic and Osteryoung Square Wave voltammetric experiments. The formal potential, E0', varied with pH to give a slope of about - 34 mV pH-1. The surface concentration, Γ, of the ruthenium redox centers was found to be 1.591 x 10-11 mol cm-2. By electrostatically doping the Au/SAM/Horseradish peroxidase at an applied potential of +700 mV vs Ag/AgCl, a biosensor was produced for the amperometric analysis of hydrogen peroxide, cumene hydroperoxide and tert-butylhydroperoxide. The electrocatalytic-type biosensors displayed typical Michaelis-Menten kinetics with their limits of detection of 6.45 M, 6.92 M and 7.01 M for hydrogen peroxide, cumene hydroperoxide and tert-butylhydroperoxide respectively.South Afric
