Letterkenny Institute of Technology , formerly the Regional Technical College, Letterkenny and still occasionally referred to as The Regional, particularly by aged citizens, is a third level institution serving County Donegal and the north-west of Ireland. Based at Letterkenny, County Donegal, it is today one of the largest places of third level education anywhere in Ulster. Wikipedia.

Scrums are particularly useful in the development of enterprise scale applications due to the size of the task and number of disparate inputs required. Given that the team may include members with lesser capabilities as well as seasoned developers it may be difficult for some to communicate their perceived inadequacies. Admitting in a Scrum that a piece of work is incomplete or incorrect can be daunting. This early investigative work outlines observations, over a two year period, on encouraging developers to 'Soapbox' their issues/faults. © 2015 IEEE. Source

This paper presents an outline of the issues encountered in the progression from wired PCs to supporting Bring Your Own Device (BYOD) for learners. The paper also documents the simultaneous transition to cloud hosting of teaching resources. The paper describes the issues that Letterkenny Institute of Technology faced in the planning and evaluation phase during the move to BYOD. It is expected that the details provided here will be of benefit to other educational institutions considering such a move. Source

Supporting modern workers and learners requires a shift in attitude of IT managers worldwide. Movement to bring your own device with further resources on the cloud seems inevitable. However despite the trend toward mobility and flexibility in IT there is a significant requirement for BYOD users to re-evaluate their attitude toward the security of their own devices and the resources they utilize on the cloud. This paper outlines an evaluation of business user's attitudes towards utilizing their own devices for business. The paper also outlines the results of a survey of on business users attitudes towards resources stored on the cloud. Finally recommendations are made regarding the best practice in aiding the users comprehension of security risks in BYOD and the Cloud © 2012 Natl Inst for Research. Source

In ultra-low data rate wireless sensor networks (WSNs) waking up just to listen to a beacon every superframe can be a major waste of energy. This study introduces MedMAC, a medium access protocol for ultra-low data rate WSNs that achieves significant energy efficiency through a novel synchronisation mechanism. The new draft IEEE 802.15.6 standard for body area networks includes a sub-class of applications such as medical implantable devices and long-term micro miniature sensors with ultra-low power requirements. It will be desirable for these devices to have 10 years or more of operation between battery changes, or to have average current requirements matched to energy harvesting technology. Simulation results are presented to show that the MedMAC allows nodes to maintain synchronisation to the network while sleeping through many beacons with a significant increase in energy efficiency during periods of particularly low data transfer. Results from a comparative analysis of MedMAC and IEEE 802.15.6 MAC show that MedMAC has superior efficiency with energy savings of between 25 and 87 for the presented scenarios. © 2011 The Institution of Engineering and Technology.

α-Lactalbumin (α-la) is a major whey protein found in milk. Previous data suggested that α-la has antiproliferative effects in human adenocarcinoma cell lines such as Caco-2 and HT-29. However, the cell death inducing α-la was not a naturally occurring monomer but either a multimeric variant or an α-la:oleic acid complex (HAMLET/BAMLET). Proteolysis showed that both human and bovine α-la are susceptible to digestion. ELISA assays assessing cell death with the native undigested α-la fractions showed that undigested protein fractions did have a significant cell death effect on CaCo-2 cells. Bovine α-la was also more effective than human α-la. A reduction in activity corresponded with lower concentrations of the protein and partial digestion and fragmentation of the protein using trypsin and pepsin. This suggests that the tertiary structure is vital for the apoptotic effect. © 2013 Elsevier Masson SAS. All rights reserved. Source
