In this paper, the mathematical modelling of a novel Electrical Energy Storage (EES) Receiver for Solar Parabolic Trough Collector (PTC) is presented. The EES receiver is essentially a Heat Collecting Element (HCE) with built in storage in the form of thermal batteries such as the Sodium Sulphur (NaS) battery. The conceptual design and mathematical models describing the operation of the receiver are presented along with important results of model validation. When held under adiabatic conditions (a primary indicator of model validity), results were highly consistent with established PTC, models and with National Renewable Energy Laboratory (NREL, USA) experimental data for existing SCHOTT PTR-70 and Solel UVAC3 receiver tubes, currently being used in existing PTC power plants. © 2017 Elsevier Ltd

Approximately 90 girls and young women will compete for prizes at the International Telecommunications Union’s (ITU) Girls in Information and Communication Technology (ICT) Day Caribbean Hackathon on Thursday, April 27, 2017. Students, from high schools, universities and community colleges — including Wolmer’s Girls’, Hillel Academy, St Andrew High School, St Elizabeth Technical High School, American International School Kingston, Excelsior Community College, the University of the West Indies, the University of Technology Jamaica, and Northern Caribbean University — will gather at Spanish Court Hotel, Worthington Conference Centre for a fun-filled day in celebration of International Girls in ICT Day. The ‘hackathon’, led by a group of women consultants through a joint partnership between Cotton Tree Consulting and Change Makers Development Ltd, will take place simultaneously, in Barbados and Trinidad and Tobago. The event is supported regionally by Platinum Sponsor, Scotiabank and Gold Sponsor LOOP in partnership with the University of the West Indies and locally, by Platinum Sponsor, National Commercial Bank Jamaica Ltd, and Silver Sponsor, Phase 3 Productions, and supported by the Inter-American Development Bank (IDB). Throughout the day, girls and young women will be engaged in hands-on activities, guided by a tech mentor, using ICT to create, innovate and generate solutions to various challenges. The activities include mobile app building, animation, robotics, digital video production and digital art works, and web development. A day-long immersion in ICT, the ‘hackathon’ will give the girls and young women, an opportunity to envision themselves, not only as users of technology, but creators. “With this exciting hands-on event, we hope to give girls the confidence to pursue studies and careers in ICT, to facilitate greater gender balance in the sector,” said Samantha Chantrelle of Change Makers. Bridget Lewis of Cotton Tree Consulting added, “We want girls to know that they have the power to chart their own course, in a more dynamic technology sector, which ultimately leads to, enhanced productivity and innovation and better financial results.” Throughout the day a number of local, regional and international role model tech speakers will be streamed, giving inspirational messages of support to the participants. The line-up will include Ingrid Riley, founder of SiliconCaribe (Jamaica); Leila Janah, founder of Samasource (USA); Wambui Kinya, chief strategy officer of Andela (Kenya); and Tricia Clarke Stone, co-founder and CEO of Narrative (USA). Nicole Pitter Patterson, international advisor on the project, stated: “This initiative is a key example of how women’s economic empowerment can be inclusive of girls, who will become the future women leaders, using tech to advance their economic opportunities.” Members of the public, worldwide, will be able to view the speaker presentations and the day’s happenings, by logging on to the ITU portal URL: http://www.itu.int/girlsinict Simple Facts about Girls in ICT Day Worldwide Over the last six years, over 240,000 girls and young women have taken part across 160 countries.

The purpose of this case-study is to narrate a secondary science teacher's experience of his professional development (PD) education and training in innovative technologies (IT) in the context of engaging students in environmental research projects The sources from which the narrative is derived include (1) the science teacher's reflective reports during three summer institute programs and (2) the science teacher's reflective reports while subsequently engaging students in IT-embedded environmental research projects in his classroom. The science teacher's explanations for changes in students' perception of their IT fluency illuminate his personal narrative. The science teacher attributed his growth and significant changes in students' perceptions of their IT fluency to the following mechanisms: (a) a personal commitment to developing his own and his students' IT abilities in the context of doing environmental research projects, and (b) an increase in class time devoted to science education due to school-time scheduling policy. The study implies that immersive professional development opportunities have the potential to produce significant increases in students' perceptions of their IT fluency. © 2011 Springer Science+Business Media, LLC.

Bauxite inputs into the Bayer process at a Jamaican refinery were found to contain approximately 0.4% inorganic carbon (or 3.2% CaCO3) and 0.2% organic carbon. Thermal treatment or heating of 10 g bauxite samples for 30 min at temperatures ranging from 300 to 1000 C was shown to significantly reduce levels of both organic (up to 93%) and inorganic carbon (up to 100%); however, there was an accompanying noticeable decrease in solubility of bauxite ore calcined at temperatures above 300 C based on predigestion alumina/caustic (A/C) ratios in spent liquor at 99 C. X-ray diffraction and X-ray database (XDB) spectral analysis of the calcined bauxite (>600 C) demonstrated the appearance of corundum (α-alumina), a form of aluminum oxide much less soluble than boehmite or gibbsite. © 2012 American Chemical Society.

The ability for DNA mismatch repair, after oxidative stress-induced DNA damage, is critical for the persistence of Porphyromonas gingivalis in the inflammatory environment of the periodontal pocket. Our previous report demonstrated that, in contrast to other organisms, the repair of oxidative stress-induced DNA damage involving 8-oxo-7,8-dihydroguanine (8-oxoG) may occur by a yet-to-be described mechanism in P. gingivalis. 8-oxoG does not block DNA replication; rather, it mispairs with adenine, which can be repaired by the MutY glycosylase. To determine the function of the P. gingivalis MutY homologue in DNA repair, it was insertionally inactivated using the ermF-ermAM antibiotic cassette and used to create a mutY-deficient mutant (FLL147) by allelic exchange mutagenesis. FLL147 had an increased rate of spontaneous mutation and was more sensitive to hydrogen peroxide compared with the wild-type W83 strain. DNA oligomers containing a site-specific 8-oxoG:A mispair was repaired similarly in both the P. gingivalis mutY-defective mutant and wild-type strains. The P. gingivalis mutY homologue was shown to complement the mutY mutation in Escherichia coli. In a gel mobility shift assay, the purified recombinant MutY is able to bind an oligo containing an 8-oxoG:A mispair. Taken together, MutY may play the expected role in oxidative stress resistance in P. gingivalis. However, there may exist other redundant mechanism(s) for the removal of 8-oxoG:A mismatch in this organism. © 2011 John Wiley & Sons A/S.

Deception and dishonesty in online exams are believed to link to their unmonitored nature where users appear to have the opportunity to collaborate or utilize unauthorized resources during these assessments. The primary goal of this study was to investigate the deterrent effect of Webcam-based proctoring on misconduct during online exams. This study involved an experimental design in comparing an experimental group and a control group. Both groups attended the same course, used the same e-learning system, with the same instructor, and took the same set of online exams. One group was monitored by a Web-based proctor while the other was not monitored. The results indicated no statistically significant difference between the scores of the two groups, although the non-proctored group had slightly higher scores. There was a statistically significant difference found on the time taken to complete the online exams where the proctored group used significantly less time to complete their exams. The results of a post-experiment survey indicated that those who were not proctored perceived to have experienced greater levels of opportunity to engage in misconduct than those who were monitored by a Web-based proctor. © 2015 Elsevier Ltd.

Purpose - The purpose of this paper was to examine the impact of the e-library on the usage of library resources at Northern Caribbean University. The objective was also to determine whether or not it is worthwhile to continue to invest in electronic resources in a period of declining library budgets and easy access to electronic resources via the internet. Design/methodology/ approach - Data were collected from library statistical reports as well as from a survey administered to students and faculty on both the main and extension campuses over a four-week period. The population studied in the survey was 280 faculty members and 5,340 students. Of this number, a stratified random sample of 50 faculty members and 200 students was selected. Findings - The study shows that the provision of e-library resources has increased overall usage of library materials as patrons continue to use print resources in tandem with electronic versions. The study also found that the electronic library resources are helpful to patrons and play an important role in enhancing access to library resources necessary for quality research papers and academic excellence on a whole. Originality/value - It is hoped that the findings of this paper will serve to assist the librarians and faculty at Northern Caribbean University and other similar institutions in selecting and acquiring the most appropriate format of information resources that will both satisfy the needs of their library users and fit within their library budget. Recommendations for improving the e-library service include continuous collaboration between librarians and faculty in selecting and acquiring the most appropriate format of resources to support the curriculum and satisfy the users' needs, constant marketing of the resources and on-going training in their use, and periodic assessment of the collection to ensure quality and competitiveness in light of other readily available electronic resources on the internet. © Emerald Group Publishing Limited.

Several cyanide-associated health disorders have been linked with frequent consumption of mildly toxic cassava (Manihot esculenta crantz) products in individuals on a low-protein diet. Production of bread from cassava often involves application of prolonged physical pressure (pressing) to the freshly grated root for several hours. This study aimed to determine effects of pressure and wetting on grated cassava. Six treatments were applied: confining pressure for 12 h, wetting for 4 h at 25 °C, 2 h at 25 °C, 2 h at 40 °C, and 2 h at 50 °C, or each of the above followed by pressure for 12 h. Treatments released cyanide from samples in the order: 2-h wet at 50 °C + pressing >4-h wet at 25 °C + pressing = 2-h wet at 40 °C + pressing >2-h wet at 25 °C + pressing = 4-h wet at 25 °C >12-h pressing. Wetting for 2 h at 50 °C followed by pressure for 12 h reduced cyanide levels by at least 20% more than that of any other treatment. The combination of moisture and pressure enhanced the contact time between linamarin and linamarase to increase the release of hydrogen cyanide. © 2010 Institute of Food Technologists ®.

The concentrations of nine residual metals in some Jamaican foods were determined using inductively coupled plasma mass spectrometry technique. Cadmium concentration was highest inyellow yam (0.21 mg/kg). Sweet potato had the highest concentrations of lead (0.31 mg/kg), arsenic (0.70 mg/kg) and mercury (0.35 mg/kg). Samples from Grove Place exceeded the regulatory limitsof0.1 mg/kg for cadmium, lead and arsenic and 0.05 mg/kg for mercury. Significant correlations were found between soil and agricultural produce concentrations for cadmium and lead (r2 C 0.5). These results suggest that the elements were available in soluble forms in the soil for absorption by food crops. © Springer Science+Business Media, LLC 2012.

Rapid weathering of strong, hitherto un-weathered shale rocks was fast enough to have been measurable weekly (>4 mm depth per week). Regular early morning rain showers followed by hot, dry afternoons caused frequent wet/dry cycles which facilitated rapid slaking of the shale. Other landslips occurred concurrently on the south bank of the Wild Cane River, where the rock beds dip towards lower ground. Resistance to impacts in the rock fabric was equally low after decades, or weeks of exposure. It was concluded that the combination of high frequency wet/dry cycles on steeply dipping shale beds, and rock attitude caused very rapid weathering. Rapid slaking of the illitic shales could cause high turbidity levels in contiguous aquatic environments. Building foundations and roads could be rapidly de-stabilized even on such freshly exposed, apparently consolidated sites. © 2009 Springer-Verlag.
