The MORET code is a simulation tool that solves the transport equation for neutrons using the Monte Carlo method. It allows users to model complex three-dimensional geometrical configurations, describe the materials, define their own tallies in order to analyse the results. The MORET code has been initially designed to perform calculations for criticality safety assessments. New features has been introduced in the MORET 5 code to expand its use for reactor applications. This paper presents an overview of the MORET 5 code capabilities, going through the description of materials, the geometry modeling, the transport simulation and the definition of the outputs. © 2014 Elsevier Ltd.All rights reserved.

This paper describes the implementation of a well-known vector control scheme for a Superficial-Permanent Magnet Synchronous Machine (S-PMSM) with a sensorless algorithm based on the estimation of back-EMF. The highlight here is the novel and extensively evaluation of this sen-sorless algorithm, from the application point of view. For this, different kinds of torque-speed curves are applied so that the load-dynamic is manipulated (load-side) and speed-response of the sensorless (motor-side) is analyzed. Based on such results, robustness and performance are defined. All the results were obtained from real experiments, using a coupled system as described in Section 6 (Fig. 5 and Table 1). © VDE VERLAG GMBH.

The recent research and field experiences in CPV systems have proved that this technology has present and potential advantages when compared with other sources of energy. Despite of that, if this technology wants to initiate its learning curve with the increment of the production and the consequent price reduction, it is necessary an institutional support that allows this technology to compete against other sources of energy through the creation of a favourable and attractive economic environment for potential investors to get interested in this new technology. Nowadays, Spain is a world CPV referent. The research developed by some of its organism and the industrial experience obtained in the past years through the installation of thousands of MW, is a guarantee of its scientific and industrial potential. The intention of this report is to justify the reasons to set aside a power cap of 10 MW in the Spanish PV regulatory framework dedicated exclusively to CPV systems, and the increment of the feed-in tariff in 10.2 c€/kWh over the present tariff and to reduce progressively this support in a 13% annual until it reaches the flat PV tariff. © 2010 American Institute of Physics.

An extensive protein hydrolyzate was produced starting from sunflower defatted seed meal, an abundant by-product of biodiesel chain oil extraction. Two-step enzymatic hydrolysis was carried out using sequentially Alcalase-Flavourzyme enzymes and a high quality hydrolyzate was produced with an interesting composition in terms of nutrient, amino acid, and peptide content for application in conventional and organic agriculture. The biostimulant properties of the hydrolyzate were investigated by carrying out auxin and gibberellin-like activity assays in Petri dishes on garden cress (Lepidium sativum L.) and lettuce (Lactuca sativa L.) seedlings and by conducting experiments in pot on maize plants. The sunflower hydrolyzate showed auxin-like, but no gibberellin-like activity and interesting effects on plant root elongation suggesting a potential use of the product as an effective biostimulant in the agricultural field. © 2014 Elsevier B.V.

Isatis indigotica Fortune is an herbaceous plant belonging to the Brassicaceae family, whose leaves and roots are rich in active compounds popularly used as natural dyes and/or for their pharmacological activity. Few studies are available on its seeds production and chemical composition. This study evaluated the seed yield and active compounds of I. indigotica Fortune (Chinese woad) with the aim to investigate its intra-species chemotypic, phenotypic and productive variations. A field experiment was carried out in Central Italy under Mediterranean climate, comparing four I. indigotica accessions. The plant phenological, morphological and productive characteristics (siliculas and seed yields) have been evaluated and the seeds analysed for fatty acid composition and glucosinolate patterns. The four accessions, grown as winter annual crop, showed similar phenological development but a different percentage of plants that turn to flower. All the genotypes showed good adaptability to the environmental conditions and good agronomical performances, with good siliculas yield (1.36±0.08tha-1) and oil content (36.8±0.82% w/w). Significant differences among the accessions were observed for the fatty acid and glucosinolate profiles. The oil was rich in mono- and polyunsaturated fatty acid (58% and 32% as mean value, respectively) with major differences for the oleic and α-linolenic acids. The erucic acid content ranged from 16 to 21%. In relation to the glucosinolates, the major differences were recorded for progoitrin, epi-progoitrin, gluconapin and glucobrassicin. The high polyunsaturated fatty acid concentration of I. indigotica seeds, together with its interesting glucosinolate content, open new perspectives for sustainable biobased production. © 2015 Elsevier B.V.

The main co-products of biodiesel and biolubricant chains are defatted oilseed meals and crude glycerin, generally considered as by-products and mainly used in animal feeding, bioenergy production and other minor uses. However, these co-products could have other interesting features, and high value added outlets could be developed in order to significantly improve the overall economic and environmental impact of the entire biodiesel chain. When defatted seed meals derive from some specific oilseed crops belonging to Brassicaceae they are characterized by high levels of glucosidic molecules potentially able to release biologically active compounds by means of an enzymatic hydrolysis reaction. The second biodiesel chain by-product, crude glycerin, contains glycerol and some impurities (including water) up to 20%. This manuscript reports in vitro and in vivo bioassay results on the application of crude glycerin and defatted seed meals of some Brassicaceae species (Brassica carinata, Brassica nigra, Barbarea verna, Crambe abyssinica) in seed germination inhibition. These features open new perspectives for obtaining bio-based products for weed control, starting from both main co-products of the biodiesel chain. Indeed, the results confirmed the inhibitory effect of crude glycerin and seed meals used alone and, moreover, showed a synergistic activity when combined. As expected, the inhibitory activity was correlated to glycerol concentrations and to the quali-quantitative release of isothiocyanates from defatted seed meals. © 2015 Elsevier B.V.

Over the last decade, many pest control techniques have seen substantial changes mainly due to the EU directive 2009/128/EC which relates to the registration process for new products and their toxicity. Thus, the list of pesticides is continuously revised and modified to include new plant protection products which have to be safer for human health, food quality and less polluting for the environment. These decisions increase the importance of and consequently the interest in non-chemical alternatives, including physical systems and bio-based products and the Directive clearly reports the need to define new non-chemical control systems in crop management and defense, as a partial or total alternative to conventional pesticides.At the same time, several crops particularly adapted to the pedoclimatic conditions of southern Italy, such as trees belonging to the genus Citrus, are suffering due to presence of several pests and pathogens that can lead to considerable reductions of yield quality and quantity, and that are often resistant to the most common pesticides. This paper reports and discusses the results of trials carried out in 2011 on the efficacy of natural formulations based on products deriving from Brassica carinata (Ethiopian mustard) on Citrus groves in southern Italy against aphids (Aphis gossypi), mites (Tetranychus urticae, Panonychus citri), scales (Protopulvinaria pyriformis, Icerya purchasi, Unaspis yanonensis) and whiteflies (Aleurothrixus floccosus,). In general, the results were positive, suggesting that the experimental liquid formulations can represent a total or partial alternative to agrochemical pesticides and also an interesting option for organic farming. © 2015 Elsevier B.V.

Two liquid formulations based on Brassica carinata oil and defatted seed meal were tested as treatments to control the red spider mite (Tetranychus urticae Koch) on eggplants in open field conditions. These products were compared to a commercial chemical acaricide (fenazaquin), which is very effective, but whose use was recently limited to ornamentals in greenhouse due to its environmental risks. The application in these trials was therapeutic, the first treatment was distributed at the time of appearance of at least five mobile mites (adults and/or larvae) per plant. The 2-year results indicated that the application of both formulations have a clear effect in containing mites, statistically different from the untreated control. Moreover, the ability of pest control of the formulation with the higher concentrations of oil and defatted seed meal was not different from the chemical treatment. Treatment efficacy clearly decreased after 21 days, but within a preventive treatment plan these formulations could represent an interesting additional bio-based option both in conventional and organic farming. © 2015 Elsevier B.V.
