Life cycle cost of electricity generated by marine renewable technologies is determined by multiple factors including energy production capability, capital costs, and operating and maintenance (O&M) costs, as well as multiple other logistical, permitting, environmental, and finance cost factors. ORPCs direct experience has been that operating and maintenance costs are dominant in the cost structure. It is clear that for marine renewable energy systems to be commercially viable they must demonstrate exceptionally high reliability and availability. ORPC is now addressing these cost, efficiency and reliability issues in order to achieve commercial status. This Project is a critical next step in commercialization of ORPCs hydrokinetic power system technology for the European market. Ultimate Project goals are to develop a complete power transfer system from prime mover to electrical grid with normal maintenance intervals of greater than five years, and availability of greater than 98%. Intermediate goals are to deliver a system with design maintenance intervals of greater than five years, and availability greater than 96%. The projects primary objectives are listed below: 1. Develop wet gap electrical generator design capable of operating in seawater flooded condition 2. Develop advanced bearings and seal designs for hydrokinetic machines 3. Develop and implement control strategies to maximize power output and power quality for multiple prime mover designs 4. Develop and implement advanced health monitoring system 5. Validate the system design work by integrated full scale lab testing of system 6. Integrate these components into a baseline ORPC hydrokinetic turbine and assess associated economic improvements 7.

The fishing industry in the EU and elsewhere produces an increasing mass of negative value crustacean shell waste (>6 MTPA), whose current disposal in landfills results in significant costs and risks to human health as well as to the environment. While in Asia small amounts of shrimp waste are processed to chitosan, the high CaCO3 content of EU crab shell waste has prevented cost effective conversion to value adding products. The project will develop an integrated biorefinery platform transforming the chemical constituents of EU, African and Asian crustacean shell waste into drop-in and novel chemical intermediates to produce high value, high performance bio-based polymers at high atom efficiencies. The innovative process comprises pretreatment steps to facilitate downstream enzymatic depolymerisation and conversion of sugars into chemical building blocks utilizing enzymatic and whole-cell biocatalysis routes. Biocatalyst development requires application of genomics techniques in combination with green-chemical and process-engineering know-how. Sustainable purification technologies will enable integration of monomers into current industrial polymerization processes. Biowaste streams will be valorised for the production of bioenergy to improve process efficiency and greenhouse gas footprint. The environmental impact of the process chain will be evaluated by a cradle-to-product life cycle analysis. Process scale-up will be linked with modelling and optimization studies to demonstrate economic viability. The consortium of 5 academic, 4 SME and 2 large industrial partners has the technical and management expertise to rapidly transfer laboratory scale results into novel industrial product lines at an accelerated pace. Key consortium members are from 5 different EU and 2 associated ICP states, which allows for strategic technology transfer from high- to low-tech driven countries, fostering the development of sustainable economies in the EU and beyond.

Like many natural resource-based processing industries, the seafood processing sector gives rise to a significant volume of organic waste. Environmental issues, economic concerns and legal restrictions regarding the disposal of processing wastes have led to increased research in the discovery of alternative value-added products, such as bioactive peptides from these waste streams. Bioactive peptides have various physiological functionalities in the human body following consumption and these include antihypertensive, antiamnesiac, mineral-binding, immunodulatory, antioxidative and antithrombotic activities. The search for bioactive peptides from a variety of different sources has become a major area of research with potential for the functional foods sector. The isolation of bioactive peptides typically involves the hydrolysis of the protein of choice with different proteolytic enzymes, alone or in combination with Generally Recognised as Safe (GRAS) micro-organisms. This review details information on angiotensin I-converting enzyme (ACE) and prolyl endopeptidase (PEP) inhibitors derived from natural, marine and marine processing waste streams and their potential for use as high-value added bioactive peptides. © 2011 Elsevier Ltd.

Watermarking is the process of embedding information in a carrier in order to protect the ownership of text, music, video and images, while steganography is the art of hiding information. Normally watermarks are embedded in images but remain visible in the majority of commercial image databases, such as Getty (gettyimages.ie) or iStock Photo (istockphoto.com). However this leaves traditional watermarking techniques vulnerable to tampering. Thus the advantage of using steganographic techniques for watermarking is that the watermark is resistant to detection and consequently to tampering. Robustness is a characteristic of critical importance, in order that a watermark is to survive image manipulation and enhancement processes, as well as intentional attacks, to ensure piracy is prevented. The aim of this work is to produce a novel hybrid digital watermarking technique, based on the exploitation of both the RGB and the YCbCr colour spaces, using spatial domain techniques. Results demonstrate that the proposed hybrid technique can withstand levels of geometric attacks and processing attacks up to a point where the commercial value of the images tested would be lost. Results also demonstrate technical and performance improvements over existing methods, in terms of security and algorithm efficiency, while taking inspiration from steganography, to avoid drawing attention to the fact that an image contains hidden information. © 2012 Elsevier B.V.

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.

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.
