Alternative Energy at a Steel Mill

More than ever alternative energy solutions are being discussed including potential legislative action. With the use of fossil fuels being the most abundant and most controversial sources of energy, new solutions must be found. This paper looks at the economic and technical feasibility of different types of alternative energy and cogeneration applications within a steel mill. This paper examines alternative energy systems. The systems examined include Solar systems, thermal electric materials, and an Organic Rankine Cycle cogeneration project. None of the projects has limiting technical feasibility issues however each of the projects face economically limiting factors. Taking into account tangible and non-tangible factors the solar system and Organic Rankine Cycle cogeneration project are recommended for further study and potential installation.

Historiografia del «Ball de Torrent»: de la moixiganga barroca al quadre de balls populars valencians (1692-1929)

El Ball de Torrent és una moixiganga dramàtica popular escenificada a la ciutat de València i altres indrets del País Valencià des de finals del segle XVII fins a principis del segle XX. Estava organitzada per agrupacions gremials, juntes d’hospitals o clavaris de festes i protagonitzada per personatges agrupats en comparses que representaven una paròdia sobre les relacions entre les estructures de poder i les classes populars. Tot i la variabilitat segons el moment històric, es conforma com una mescla de quadres amb danses, música i jocs teatrals. El ball interacciona de diverses formes amb algunes festes valencianes i és, probablement, una de les mostres de teatre de carrer més nostrades i menys estudiades de la València Moderna. En aquest article es realitza una revisió bibliogràfica crítica i una primera anàlisi historiogràfica.

Impact de l’âge et des variations pluviométriques sur la croissance du pin d’Alep (Pinus halepensis. MILL): Cas du peuplement artificiel de la forêt domaniale de Tlemcen. (Algeria)

La comparaison des résultats de l’analyse dendrochronologique et dendroclimatologique du Pin d’Alep de la forêt domaniale de Tlemcen a été réalisée en conditions stationnelles particulières. L’analyse de la croissance des cernes annuels et des rapports des écarts relatifs des cernes successifs montrent une nette tendance régressive chez les arbres jeunes. La sensibilité moyenne (SM) et les coefficients d’inter datation (SR) respectifs aux jeunes arbres et aux plus âgés confirment la dépendance assez forte des premiers aux facteurs climatiques particulièrement à la pluviométrie. Les résultats de ce travail ont permis d’établir une relation pluviométrie / accroissement radial en fonction de l’âge de leur formation. Ainsi, il est établi qu’à partir de ces résultats particulièrement ceux des valeurs des sensibilités moyennes (SM) que les conséquences probables des variations climatiques influentes sensiblement sur les jeunes sujets. Aussi pour éviter les changements d’ordre physio biologiques liés au vieillissement des arbres, il est préférable de comparer les cernes sur une période de 40 à 50 ans comme c’est le cas des six échantillons choisis dans la zone d’étude.

Sport-Specific Practice and the Development of Expert Decision-Making in Team Ball Sports

The role of sport-specific practice in the development of decision-making expertise in the sports of field hockey, netball, and basketball was examined. Fifteen expert decision-makers and 13 experienced non-expert athletes provided detailed information about the quantity and type of sport-specific and other related practice activities they had undertaken throughout their careers. Experts accumulated more hours of sport-specific practice from age 12 years onwards than did non-experts, spending on average some 13 years and 4,000 hours on concentrated sport-specific practice before reaching international standard. A significant negative correlation existed between the number of additional activities undertaken and the hours of sportspecific training required before attaining expertise, suggesting a functional role for activities other than sport-specific training in the development of expert decision-making.

Quaternary refugia of the sweet chestnut (Castanea sativa Mill.): an extended palynological approach

Knowledge about the glacial refugia of the thermophilous European Castanea sativa Mill. (sweet chestnut) is still inadequate. Its original range of distribution has been masked by strong human impact. Moreover, under natural conditions the species was probably admixed with other taxa (such as Quercus, Fraxinus, Fagus, Tilia) and thus possibly represented by low percentages in pollen records. In this paper we try to overcome the difficulties related to the scarcity and irregularity of chestnut pollen records by considering 1471 sites and extending the palynological approach to develop a Castanea refugium probability index (IRP), aimed at detecting possible chestnut refugia where chestnuts survived during the last glaciation. The results are in close agreement with the current literature on the refugia of other thermophilous European trees. The few divergences are most probably due to the large amount of new data integrated in this study, rather than to fundamental disagreements about data and data interpretation. The main chestnut refugia are located in the Transcaucasian region, north-western Anatolia, the hinterland of the Tyrrhenian coast from Liguria to Lazio along the Apennine range, the region around Lago di Monticchio (Monte Vulture) in southern Italy, and the Cantabrian coast on the Iberian peninsula. Despite the high likelihood of Castanea refugia in the Balkan Peninsula and north-eastern Italy (Colli Euganei, Monti Berici, Emilia-Romagna) as suggested by the IRP, additional palaeobotanical investigations are needed to assess whether these regions effectively sheltered chestnut during the last glaciation. Other regions, such as the Isère Département in France, the region across north-west Portugal and Galicia, and the hilly region along the Mediterranean coast of Syria and Lebanon were classified as areas of medium refugium probability. Our results reveal an unexpected spatial richness of potential Castanea refugia. It is likely that other European trees had similar distribution ranges during the last glaciation. It is thus conceivable that shelter zones with favourable microclimates were probably more numerous and more widely dispersed across Europe than so far assumed. In the future, more attention should be paid to pollen traces of sporadic taxa thought to have disappeared from a given area during the last glacial and post-glacial period.
