Decision trees in selection of featured determined food quality

The determination of food quality, authenticity and the detection of adulterations are problems of increasing importance in food chemistry. Recently, chemometric classification techniques and pattern recognition analysis methods for wine and other alcoholic beverages have received great attention and have been largely used. Beer is a complex mixture of components: on one hand a volatile fraction, which is responsible for its aroma, and on the other hand, a non-volatile fraction or extract consisting of a great variety of substances with distinct characteristics. The aim of this study was to consider parameters which contribute to beer differentiation according to the quality grade. Chemical (e.g. pH, acidity, dry extract, alcohol content, CO(2) content) and sensory features (e.g. bitter taste, color) were determined in 70 beer samples and used as variables in decision tree techniques. This pattern recognition techniques applied to the dataset were able to extract information useful in obtaining a satisfactory classification of beer samples according to their quality grade. Feature selection procedures indicated which features are the most discriminating for classification.

Algebraic Curves of Low Convolution Degree

AbstractStudying convolutions of hypersurfaces (especially of curves and surfaces) has become an active research area in recent years. The main characterization from the point of view of convolutions is their convolution degree, which is an affine invariant associated to a hypersurface describing the complexity of the shape with respect to the operation of convolution. Extending the results from [1], we will focus on the two simplest classes of planar algebraic curves with respect to the operation of convolution, namely on the curves with the convolution degree one (so called LN curves) and two. We will present an algebraic analysis of these curves, provide their decomposition, and study their properties.KeywordsCurve VersusAlgebraic CurfGeometric DesignRational CurfHermite InterpolationThese keywords were added by machine and not by the authors.

Replicating the natural rain process for a sustainable distributed water production: more water with less consumed energy

Our society is in front of numerous challenges, trying to meet world’s increasing water needs, as: plastic waste from bottled water, massive water demand, pollution of superficial waters, scarcity, sanitation or climate change. The main existing drinking water solutions, intending to overcome the low quality/scarcity of superficial fresh water sources, are bottled water, desalination plants, water tanks or aquifers. However, they all present significant gaps, as they are unsustainable, polluting or they require high CAPEX/OPEX. On the other hand, atmospheric water generators have a reduced cost/l and although, they constitute a promising, though yet unknown solution for the domestic sector, they currently lack energy efficiency, manufacturing capacity and solid sales network. These gaps generate significant market opportunities in the drinking water industry (expected to reach €1.2 trillion by 2025) for our innovation.
With GENAQ we aim to provide a drinking water generation solution wherever needed with zero environmental impact. Our AWGs are drinking water production units harvesting the humidity in the air to produce condensed drinking water of high purity anywhere in the world. We produce water with excellent properties, which fully complies with WHO standards/EU laws and is certified by EU health authorities. Our system decreases the use of plastic bottles, and achieves 50% more water production with 150% reduced energy consumption (0.19 kWh/l), compared to existing AWG solutions under the same conditions. Our AWGs can be autonomous, using sustainable power sources, resulting in almost zero OPEX. The successful commercialization of this project, based on the distributed production of water will reach a cumulative turnover of €135.6M by 2025. Based on our initial business plan, we estimate to sell over 17,000 units/year, create €21.61M cumulative profit, generate ROI of 3.68 and create in total 356 new jobs after five years of commercialization.
Development of a world-level neuroengineering research centre by european twinning

The project BrainTwin will enhance networking activities and strengthen the research collaboration in the field of Neuroengineering between leading research institutions in Romania, Germany and Spain with the support of knowledge transfer organisations from Austria and Germany.
Neuroengineering is a discipline with high potential for the future that uses engineering techniques to study, restore, replace, or enhance neural systems. It comprises the application of engineering principles and techniques to the field of neuroscience. Bringing together research departments from medical sciences and engineering fields have the potential to achieve further significant progress e.g. in the comprehension and care of neurodegenerative diseases, as well as in the development of brain-connected prosthetics.
The city of Iasi in the North-East of Romania is a strong research and higher education hotspot . The Technical University Gheorghe Asachi of Iasi (TUIASI) is an excellent university in engineering fields and is part of the North East Regional Innovative Cluster for Structural and Molecular Imaging (the only medical imaging cluster in Romania). For this reason, TUIASI have the strategy to develop a new centre for research and education in the field of Neuroengineering and will need the strong support of internationally-leading counterparts in Germany and Spain. This twinning exercise will enhance the scientific and technological capacity by knowledge exchange with a focus on early stage researchers, strengthen the research management skills and visibility of Romanian Neuroengineering Research in order to compete at international level and widen scientific excellence and innovation capacity of all the Partners.
The development of an International Projects Support Centre for proposal preparation and project management/administration, as well as joint workshops and summer schools, short-term staff exchanges and expert twinning visits will permit to achieve these objectives.
Development and valorisation of port museums as natural and cultural heritage sites

The overall objective of Muse project is developing, enhancing and linking port museums as natural and cultural heritage sites.

The Port-Museum is a dynamic place of research, collection, exchange and deepening of knowledge linked to the traditions of the sea and of coastal communities.

Muse project has a clear strategy, based on the involvement of local stakeholders: fishermens, carpenters, cookers, local associations that through their “day-to-day” work, preserve over the time the traditional lifestyle of the maritime community.

The concept of ‘port museum’ was born from the idea of investing in culture and nature to guarantee the social and economic sustainable development in coastal and marine areas, starting from the Apulian regional legislation (regional law n. 15 of the 6th July 2011) and the experiences of “eco museums” in many European countries.

Together with local community, MUSE project aims to build and strenght an Adriatic – Ionian network of Ports Museum; it includes the port museum already created (in Tricase, Italy) and areas where the natural and cultural heritage linked to the values of port museums exist but are not fully established and developed in Corfu and Messolonghi, in Greece.

Lead Partner of the project is the Municipality of Tricase; the project partners are CIHEAM BARI, the Municipality of Messolonghi, the Port Authority of Corfu and the European Regional Framework for Cooperation (ERFC-Greece).

A simple, sensitive and efficient assay for the determination of d- and l-lactic acid enantiomers in human plasma by high-performance liquid chromatography

A new method for the simultaneous determination of D- and L-lactic acid in human plasma has been developed using high-performance liquid chromatography (HPLC) with fluorescence detection. This method is based on the reaction of lactic acid with (2S)-2-amino-3-methyl-1-[4-(7-nitro-benzo-2,1,3-oxadiazol-4-yl)-piperazin-1-yl]-butan-1-one (NBD-PZ-Val) in the presence of O-(7-azobenzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (HATU) and N-ethyldiisopropylamine (DIEA) to produce fluorescent diastereomeric derivatives that were easily monitored fluorimetrically at λ(ex)=490 nm and λ(em)=532 nm. The separation was achieved by use of a C18 analytical column (Synergy Hydro 150 mm x 3 mm i.d., 4 μm). The calibration curve was linear over the on-column concentration range of 10-200 μmol/L for D-lactic acid and 0.5-4.0 mmol/L for L-lactic acid. The sensitivity was good with a limit of detection of 5.24 μmol/L for D-lactic acid and 0.15 mmol/L for L-lactic acid. The analytical method was successfully applied to human plasma samples from normal healthy subjects.
Disruptive cyclone-based technology for effective and affordable particulate matter emission reduction in biomass combustion systems

A strong complementary team with more than 70 years' experience has come together to upgrade, scale-up and market launch an urgently needed affordable integrated solution for emission reduction for biomass combustion plants (CYCLOMB), which will generate 26.54M€ of cumulative profit and 97 new direct jobs by 2023. All EU countries will have to abide by new regulations (already implemented in Germany, Denmark and UK, other EU member states have to follow until 2030) which fix particulate matter (PM) emission limits under 20 mg/m3. Today no cost effective solutions exist that comply with the legislation. The CYCLOMB system achieves a 96-99% PM emission reduction, combining flue gas recycling and cyclone variable geometry. Recirculation of flue gases provides the biomass boiler with a high combustion efficiency (up to 95%) and reduces boiler emissions from 150 mg/m3 of typical automatic boilers to 80 mg/m3. By using a variable-geometry design of the attached PM abatement device a ≥96-99% particulate matter reduction is achieved. Final emission levels are always lower than 20 mg/m3 while investing only an additional 26% in PM abatement technology with respect to boiler price. It thus provides a comparative performance to the most advanced electrostatic precipitators and bag filters but at a 66% lower cost. The total annual operation and maintenance cost of biomass power plants is typically 5%-6.5% of the capital cost of small and medium capacity power plants. The implementation of CYCLOMB can reduce these maintenance costs at least 80% The PM abatement cyclone-technology solution will be optimized for the CYCLOMB integrated solution medium-scale range (200kW-5MW) ideal for medium scale district heating plants and applications in the primary sector (farms, greenhouses) and the tertiary sector (office buildings, schools, hospitals and hotels).
The unsteady nature of sea cliff retreat due to mechanical abrasion, failure and comminution feedbacks

Sea cliff retreat is often linked to large waves, heavy precipitation and seismic events, but the specific operative mechanics have not been well constrained. In particular, what is the role of mechanical abrasion by beach sediments in cliff/platform evolution and how does it relate to the episodic nature of cliff retreat observed at certain locations? Here we present a simple, numerical model of sea cliff retreat that incorporates mechanical abrasion of a basal notch, threshold-controlled failure of the cantilevered block, and a feedback mechanism wherein retreat is dependent on the rate of sediment comminution within the surf zone. Using shore platform and cliff characteristics found in two coastal settings (the central California coast and the English North Sea coast), the model produces retreat rates comparable to those observed via field measurements. The highest retreat rates coincide with the steepest shore platforms and increasing wave height. Steeper platforms promote wave access to the cliff toe and, correspondingly, the receding cliff face produces additional accommodation space for the platform beach, preserving the erosive efficacy of the beach sediments. When exposed to energetic wave forcing, the slope of the inner platform segment controls retreat rates for concave platforms, whereas the slope of the outer platform segment exerts greater control for convex platforms. Platform beaches approached a long-term dynamic equilibrium on the concave profiles, leading to more consistent and steady retreat. Platform beaches were ephemeral on convex profiles, mirroring observed sand wave (Ord) migration on the Holderness coast, UK. These findings agree with previous field observations and support mechanical abrasion as a viable cause of temporal heterogeneity in cliff retreat rate for both coastlines.
Novel drilling technology combining hydro-jet and percussion for rop improvement in deep geothermal drilling

Deep geothermal reservoirs are being targeted for renewable energy supply worldwide. However, while international research efforts are stepping up to the challenge of overcoming the low efficiency of heat recovery from depth to the surface, the showstopper remains the slow drilling speed provided by the conventional rotary system in deep hard rocks (> 4 km). Deep drilling requires long drilling times, often resulting in unacceptably high initial investment.
ORCHYD’s new drilling technology will increase hard rock drilling rates from the current range of 1-2 m/h up to 4-10 m/h. The novelty is to combine two, previously separate, mature technologies: High Pressure Water Jetting (HPWJ) and Percussive Drilling, in a system customised for hard rock geothermal reservoirs to depths of 6 km.
Planned experiments and solid-fluid coupled models designed to reveal the critical fragmentation mechanisms under in-situ stress conditions will be used to design, build and validate, with pilot drilling tests, the new system for field operations.
The hybrid development requires optimisation of: i) release of high stress concentrations on the hole bottom while drilling, ii) slotting circumferential relieving grooves on the hole bottom using HPWJ (up to 200 MPa), iii) in-hole production of the HPWJ using a down-hole pressure intensifier activated by the drilling vibrations, hence damping out harmful drilling system vibrations and iv) an advanced down-hole percussive rotating mud hammer for drilling to derive the maximum benefit from the modified bottom-hole stress regime.
ORCHYD will decrease the drilling cost by 65% in hard rock sections. This will result in 30% reduction of the total cost of deep geothermal well construction. In addition, the new coupled Intensifier-HPWJ-Hammer system has the potential to drill and steer multi-lateral wells which greatly increase thermal connectivity, are cheaper, use far less water and are more controllable than conventional fracking stimulations.
Pulmonary hyperpolarized129Xe morphometry for mapping xenon gas concentrations and alveolar oxygen partial pressure: Proof-of-concept demonstration in healthy and COPD subjects

Diffusion-weighted (DW) hyperpolarized (129) Xe morphometry magnetic resonance imaging (MRI) can be used to map regional differences in lung tissue micro-structure. We aimed to generate absolute xenon concentration ([Xe]) and alveolar oxygen partial pressure (pA O2 ) maps by extracting the unrestricted diffusion coefficient (D0 ) of xenon as a morphometric parameter.In this proof-of-concept demonstration, morphometry was performed using multi b-value (0, 12, 20, 30 s/cm(2) ) DW hyperpolarized (129) Xe images obtained in four never-smokers and four COPD ex-smokers. Morphometric parameters and D0 maps were computed and the latter used to generate [Xe] and pA O2 maps. Xenon concentration phantoms estimating a range of values mimicking those observed in vivo were also investigated.Xenon D0 was significantly increased (P = 0.035) in COPD (0.14 ± 0.03 cm(2) /s) compared with never-smokers (0.12 ± 0.02 cm(2) /s). COPD ex-smokers also had significantly decreased [Xe] (COPD = 8 ± 7% versus never-smokers = 13 ± 8%, P = 0.012) and increased pA O2 (COPD = 18 ± 3% versus never-smokers = 15 ± 3%, P = 0.009) compared with never-smokers. Phantom measurements showed the expected dependence of D0 on [Xe] over the range of concentrations anticipated in vivo.DW hyperpolarized (129) Xe MRI morphometry can be used to simultaneously map [Xe] and pA O2 in addition to providing micro-structural biomarkers of emphysematous destruction in COPD. Phantom measurements of D0 ([Xe]) supported the hypotheses that differences in subjects may reflect differences in functional residual capacity.

Less carbon emissions of wheat–maize intercropping under reduced tillage in arid areas

Intercropping is used to increase grain production in many areas of the world. However, this increasing crop yield costs large amounts of water used by intercropped plants. In addition, intercropping usually requires higher inputs that induce greenhouse gas emissions. Actually, it is unknown whether intercropping can be effective in water-limited arid areas. Here, we measured crop yield, water consumption, soil respiration, and carbon emissions of wheat–maize intercropping under different tillage and crop residue management options. A field experiment was conducted at Wuwei in northwest China in 2011 and 2012. Our results show that wheat–maize intercropping increased grain yield by 61 % in 2011 and 63 % in 2012 compared with the average yield of monoculture crops. The intercropping under reduced tillage with stubble mulching yielded 15.9 t ha−1 in 2011 and 15.5 t ha−1 in 2012, an increase of 7.8 % in 2011 and 8.1 % in 2012, compared to conventional tillage. Wheat–maize intercropping had carbon emission of 2,400 kg C ha−1 during the growing season, about 7 % less than monoculture maize, of 2,580 kg C ha−1. Reduced tillage decreased C emission over conventional tillage by 6.7 % for the intercropping, 5.9 % for monoculture maize, and 7.1 % for monoculture wheat. Compared to monoculture maize, wheat–maize intercropping used more water but emitted 3.4 kg C per hectare per millimeter of water used, which was 23 % lower than monoculture maize. Overall, our findings show that maize–wheat intercropping with reduced tillage coupled with stubble mulching can be used to increase grain production while effectively lower carbon emissions in arid areas.
Course of the Radial Nerve in Relation to the Center of Rotation of the Elbow—The Need for a Rational Safe Zone for Lateral Pin Placement

To investigate the course and variability of the radial nerve along the lateral humerus in relation to the center of rotation of the elbow joint in the context of lateral pin placement for hinged external fixation.A total of 95 formalin-fixed upper extremities were dissected. The course of the radial nerve along the lateral aspect of the humerus was measured at 3 landmarks with respect to the center of rotation of the elbow. We analyzed the data and the landmark positions correlated with the length of the humerus.The measured positions of 3 landmarks of the radial nerve in the lateral aspect of the humerus ranged from 19% to 43% of the length of the humerus and were located, on average, 6.0, 9.7, and 13.5 cm from the lateral center of rotation.These data help predict the humeral course of the radial nerve and define a safe zone for pin implantation. However, because of variability in the course of the radial nerve, a safe zone cannot fully ensure prevention of iatrogenic injury to the nerve. The safest method of pin application remains mini-open dissection and visual implantation.Based on this cadaveric study, it is not possible to define a rational safe zone. The safest method of pin application for dynamic external fixation of the elbow is to perform a mini-open dissection with direct visualization.
