IbD will create a holistic platform for facilitating process intensification in processes in which solids are an intrinsic part, the cornerstone of which will be an intensified-by-design (IbD). The IbD approach is hinged on the use of robust data about a process to redesign, modify, adapt and alter that process in a continuous, intensified system, and will be the new paradigm in the intensification of processes based on statistical, analytical and risk management methodologies in the design, development and processing of high quality safe and tailored chemicals, pharmaceuticals, minerals, ceramics, etc. under intensified processes. The IbD Project will deliver the EU process industry with an affordable and comprehensive devices-and-processes design-platform endeavoured to facilitate process intensification (PI), which specially targets -but is not limited to- solid materials processing. Five PI industry case studies will be implemented in mining, ceramics, pharmaceutical, non-ferrous metals and chemical processes using the IbD approach and to validate the IbD methodologies, tools, PI modules, control and fouling remediation strategies and the ICT Platform itself for the industrial implementation of PI in processes involving solids. The Platform includes design modules for the commonest intensified reactors-Rotating fluidized beds, micro-structured reactor and spinning disk, among others, as well as a generic Module Builder -equipped with a set of both proprietary and third-parties design tools- for designs carried out on the basis of radically novel ideas. The IbD Platform output is basically a data set that comprises the intensified reactor design -ready to be built or assembled-, an optimised whole process design including the upstream/downstream intensified unit operations and their solids handling capability, as well as cleaning methods, etc. and the expected economic and environmental quantitative impacts.

The project HERCULES-2 is targeting at a fuel-flexible large marine engine, optimally adaptive to its operating environment. The objectives of the HERCULES-2 project are associated to 4 areas of engine integrated R&D: Improving fuel flexibility for seamless switching between different fuel types, including non-conventional fuels. Formulating new materials to support high temperature component applications. Developing adaptive control methodologies to retain performance over the powerplant lifetime. Achieving near-zero emissions, via combined integrated aftertreatment of exhaust gases. The HERCULES-2 is the next phase of the R&D programme HERCULES on large engine technologies, which was initiated in 2004 as a joint vision by the two major European engine manufacturer groups MAN and WARTSILA. Three consecutive projects namely HERCULES - A, -B, -C spanned the years 2004-2014. These three projects produced exceptional results and received worldwide acclaim. The targets of HERCULES-2 build upon and surpass the targets of the previous HERCULES projects, going beyond the limits set by the regulatory authorities. By combining cutting-edge technologies, the Project overall aims at significant fuel consumption and emission reduction targets using integrated solutions, which can quickly mature into commercially available products. Focusing on the applications, the project includes several full-scale prototypes and shipboard demonstrators. The project HERCULES-2 comprises 4 R&D Work Package Groups (WPG): - WPG I: Fuel flexible engine - WPG II: New Materials (Applications in engines) - WPG III: Adaptive Powerplant for Lifetime Performance - WPG IV: Near-Zero Emissions Engine The consortium comprises 32 partners of which 30% are Industrial and 70% are Universities / Research Institutes.

Improved separation of highly toxic contact herbicides paraquat (1,1′-dimethyl-4-4′-bipyridinium), diquat (6,7-dihydrodipyridol[ 1,2-a:2′,1′-c]pyrazine-5,8-di-ium), difenzoquat (1,2-dimethyl-3,5- diphenyl-1H-pyrazolium-methyl sulfate), mepiquat (1,1-dimethyl-piperidinium), and chloromequat (2-chloroethyltrimethylammonium) were presented by high-performance thin-layer chromatography (HPTLC). The quantification is based on a derivatization reaction, using sodium tetraphenylborate. Measurements were made in the wavelength range from 500 to 535 nm, using a light-emitting diode (LED) for excitation purposes, which emits very dense light at 365 nm. For calculations, a new theory of standard addition method was used, thus leading to a minimal error if exactly the same amount of sample content is added as a standard. The method provides a fast and inexpensive approach to quantification of the five most important quats used for plant protection purposes. The method works reliably because it takes into account losses during pre-treatment procedure. The method meets the European legislation limits for paraquat and diquat in drinking water according to United States Environmental Protection Agency (US EPA) method 549.2 which are 680 ng L -1 for paraquat and 720 ng L -1 for diquat. The method of standard addition in planar chromatography can be beneficially used to reduce systematic errors. Although recovery rates of 33.7% to 65.2% are observed, calculated contents according to the method of standard addition lie between 69% and 127% of the theoretical amounts. © Akadémiai Kiadó.

Chronic insomnia is defined by difficulties in falling asleep, maintaining sleep, and early morning awakening, and is coupled with daytime consequences such as fatigue, attention deficits, and mood instability. These symptoms persist over a period of at least 3 months (Diagnostic and Statistical Manual 5 criteria). Chronic insomnia can be a symptom of many medical, neurological, and mental disorders. As a disorder, it incurs substantial health-care and occupational costs, and poses substantial risks for the development of cardiovascular and mental disorders, including cognitive deficits. Family and twin studies confirm that chronic insomnia can have a genetic component (heritability coefficients between 42% and 57%), whereas the investigation of autonomous and central nervous system parameters has identified hyperarousal as a final common pathway of the pathophysiology, implicating an imbalance of sleep-wake regulation consisting of either overactivity of the arousal systems, hypoactivity of the sleep-inducing systems, or both. Insomnia treatments include benzodiazepines, benzodiazepine-receptor agonists, and cognitive behavioural therapy. Treatments currently under investigation include transcranial magnetic or electrical brain stimulation, and novel methods to deliver psychological interventions. © 2015 Elsevier Ltd.

In their famous work on prospect theory Kahneman and Tversky have presented a couple of examples where human decision making deviates from rational decision making as defined by decision theory. This paper describes the use of extended behavior networks to model human decision making in the sense of prospect theory. We show that the experimental findings of non-rational decision making described by Kahneman and Tversky can be reproduced using a slight variation of extended behavior networks. © 2010 Springer.

Proton Exchange Membrane Fuel Cells (PEMFCs) are complex nonlinear systems. In order to improve their durability, efficiency and to decrease the cost, time of development, design of new diagnostic tools is crucial. Powerful mathematical models of the dynamic behaviour of PEMFCs are necessary for the design and improvement of diagnostic tools. The project PUMA MIND will enhance the understanding of interaction, competitions and synergies among the mechanisms at multiple scales and lead to the development of robust dynamic macroscopic models for control-command purposes with predictive capabilities. The novel mathematical models developed by PUMA MIND will be tested by an experimental work, in order to ensure the applicability on commercial attainable components and catalysts. The most suitable catalysts for the MEA manufacturing technology will be used for these experiments. The implementation of the developed models on the mentioned above catalysts might allow a significant impact, and might also contribute to the most promising solutions based on current EU industrial available components. Operation conditions and control strategies to enhance the durability of automotive PEMFC will be derived on the basis of the multiscale modeling approach proposed by PUMA MIND.

Meter reading is the backbone of the home water billing system. If meters are read incorrectly or not read at all, it will cause a chain reaction of added events that add unnecessary expense and create customer dissatisfaction. Consortium SMEs have identified a clear need to develop a smart wireless water metering system based on the European Standard EN 13757 Communication systems for meters and remote reading of meters. The system will be suitable for use in a variety of water metering scenarios, will require no maintenance and will provide authenticable and secure data transmission as well as timely and accurate recording of the consumption of water which will help in identifying any leakages through the analysis of the actual quantity supplied and recorded by the meters. The commercial objective is to develop a powerful set of new features to the SME wireless EN 13757 platforms, to enable the products and services of consortium SMEs to keep pace, and even surpass the future needs (high autonomy, interoperability and long radio range) of the emergent Automatic Water Meter Reading (AWMR) market in Europe. The project also aims to exploit aspects of the EN 13757 standard, which are not fully exploited as yet, and in this manner to add value to a European standard
