Talea: An Ontology-based Framework for e-Business Applications Development
No full textAbstract. In this paper we present Talea, a platform aimed at supporting the development of web-based e-business applications. Talea supports a flexible matching between service provision and request. The platform can be easily customized thanks to XML-based communication, Semantic Web technologies, and the exploitation of a generator/performer design pattern which greatly simplifies the task of adding new functionality. Moreover, Talea provides multidevice access to both service providers and final users. An ontological description of the application domain, expressed in RDF/RDFS format, is exploited in order to facilitate the customization and to provide personalized navigation as well as semantic-based search. The ontology-driven personalized navigation is particularly useful for limited display devices (like smartphones or PDAs), since it reduces the amount of information displayed. A first evaluation of the current prototype is planned with a restricted number of users and will be carried on by the Local Tourist Organization.

Esperienze di propagazione della canna comune (Arundo donax L.) per talea di fusto in pieno campo.
No full textLa canna comune in ambiente mediterraneo non produce seme, pertanto, ad oggi, può essere propagata solo per via agamica utilizzando piantine micropropagate, porzioni di rizoma, talee di fusto. Tra queste modalità, le prospettive più interessanti dal punto di vista dell'economicità dell'impianto, sono a carico delle talee di fusto (Copani et al.). Con il lavoro qui riportato si è voluto approfondire le conoscenze riguardo le potenzialità di propagazione dell'Arundo donax per talea di fusto in pieno campo
Feed quality of modern varieties of Festuca arundinacea and Phleum pratense as an alternative to Lolium perenne in intensively managed grassland with different defoliation schemes
No full textAbstract Grassland production based on cutting-only and an increasing frequency of prolonged periods of drought due to climate change could lead to decreased productivity in Lolium perenne . In field experiments, we tested whether Festuca arundinacea and Phleum pratense could be suitable alternatives to L. perenne on intensively managed grassland on clay, peat and sandy soil. The three grasses were sown in mixture with Poa pratensis and Trifolium repens and subjected to different frequencies of defoliation representing a cutting-only system, simulated grazing system and a mixed system. We found that in systems with at least six defoliations, F. arundinacea represented an acceptable compromise between feed quality (6.4 MJ net energy/kg dry matter (DM), 19.3% crude protein, CP), persistence (mass proportion >90%), and DM yield (12.7 Mg/ha). However, for dairy production based on intensive cutting-only systems, the quality of F. arundinacea was insufficient (5.9 MJ net energy/kg DM, 15.6% CP). Mixtures with P. pratense as the main sown species did not differ significantly in production of net energy and CP from L. perenne in cutting-only systems on sandy soil. On peat land, all sown mixtures were invaded by Holcus lanatus. We found that under frequent defoliation conditions, H. lanatus -rich swards had comparatively good DM yields (9.2 Mg/ha) and a feed quality that would be sufficient for dairy cow nutrition (net energy, 6.2–6.4 MJ/kg DM; 18.8–20.4% CP). We conclude that there is potential to adapt the choice of grasses and mixtures in different production systems to meet the challenges of climate change
Streaming the Archives: Repurposing Systems to Advance a Small Media Digitization and Dissemination Program
No full textIn 2013-2014, Brooks Library at Central Washington University (CWU) launched library content in three systems: a digital asset-management system, an institutional repository (IR), and a web-based discovery layer. In early 2014, the archives at the library began to use these systems to disseminate media recently digitized from legacy formats. As the project progressed, the archives noted that these systems—while providing valuable storage and discovery capabilities—posed challenges when it came to metadata, interoperability, cost, preservation, and ease of access. This article details the experience of the archives in its first year using these systems.Anderson, Talea. (2015).

How German dairy farmers perceive advantages and disadvantages of grazing and how it relates to their milk production systems
No full textDairy farming in Europe and in Germany in particular, is characterized by a growing trend towards all-year-housing. Along with that the proportion of grass products as sources of energy for dairy cows is decreasing. On the other hand, society and politics strongly advocate grazing resulting in the introduction of pasture-milk programs. Little is known of the dairy farmers\’ perception of grazing and it is not clear what role their attitude towards grazing plays in their decision-making and how this is related to farm structure. To investigate these questions, we conducted a survey with face-to-face interviews on three types of German dairy farms: i.) grazing farms (n = 17), ii) exercise-pasture farms (n = 19), and iii) all-year-housing farms (n = 18). On grazing farms, pasture contributes significantly to the ration of the cows (0.2 ha grassland with 0.1 ha as pasture per cow and year; at least 6 hours of grazing on 120 days per year). Exercise-pasture farms offer their cows a much more restricted access to rather small pastures. All-year-housing farms have no grazing for dairy at all but feed their cows grass silage and hay. Farmers from grazing farms expressed a high agreement with the positive aspects of grazing (low fodder costs, low labor input, benefits for animal health and fertility), while the all-year-housing farmers were more aware of the challenges and disadvantages of grazing and expressed a high agreement with its potential negative aspects (reduced milk yield, unsuitability for large herds, insufficient access of the herd to the pastures). The exercise-pasture farmers appreciated the advantages of better fertility and better animal health and saw fewer disadvantages of grazing than the all-year-housing farmers. Utilization of grass products also differed among the three groups: grass and grass silage made up 47% of the ration on grazing farms while on exercise-pasture farms and on all-year-housing farms, grass products amounted to only 28% and 23% of the ration, respectively. The grazing farms had fewer cows (n = 69) and smaller milk yields (8,270 kg milk per cow/year) than the exercise-pasture farms (n = 109; 9,524 kg milk per cow/year) and all-year-housing farms (n = 138; 9,404 kg milk per cow/year). We also discuss the influence of the human tendency to avoid cognitive dissonance on farmers\’ responses. We conclude that in developing concepts to promote grazing, the differing attitudes and perceptions of dairy farmers and the interaction with differing farm structures need to be considered
Overexpression of TaLEA gene from Tamarix androssowii improves salt and drought tolerance in transgenic poplar (Populus simonii × P. nigra).
No full textLate embryogenesis abundant (LEA) genes were confirmed to confer resistance to drought and water deficiency. An LEA gene from Tamarixandrossowii (named TaLEA) was transformed into Xiaohei poplar (Populussimonii × P. nigra) via Agrobacterium. Twenty-five independent transgenic lines were obtained that were resistant to kanamycin, and 11 transgenic lines were randomly selected for further analysis. The polymerase chain reaction (PCR) and ribonucleic acid (RNA) gel blot indicated that the TaLEA gene had been integrated into the poplar genome. The height growth rate, malondialdehyde (MDA) content, relative electrolyte leakage and damages due to salt or drought to transgenic and non-transgenic plants were compared under salt and drought stress conditions. The results showed that the constitutive expression of the TaLEA gene in transgenic poplars could induce an increase in height growth rate and a decrease in number and severity of wilted leaves under the salt and drought stresses. The MDA content and relative electrolyte leakage in transgenic lines under salt and drought stresses were significantly lower compared to those in non-transgenic plants, indicating that the TaLEA gene may enhance salt and drought tolerance by protecting cell membranes from damage. Moreover, amongst the lines analyzed for stress tolerance, the transgenic line 11 (T11) showed the highest tolerance levels under both salinity and drought stress conditions. These results indicated that the TaLEA gene could be a salt and drought tolerance candidate gene and could confer a broad spectrum of tolerance under abiotic stresses in poplars
Persistent subretinal fluid following diabetic tractional retinal detachment repair: risk factors, natural history, and management outcomes
No full textPurpose: To study the natural history, anatomical and functional outcomes of persistent subretinal fluid (SRF) after pars plana vitrectomy (PPV) for diabetic tractional retinal detachment (TRD) and combined traction-rhegmatogenous retinal detachment (TRRD). Methods: Retrospective interventional case series of 43 patients (46 eyes) with persistent SRF following PPV for diabetic TRD or combined TRRD from January 2010 to December 2017 at single tertiary institution. Primary outcomes included best corrected visual acuity (BCVA) and central foveal thickness (CFT). Results: Thirty-one eyes (67.4%) had macula-off TRD, 5 (10.9%) had fovea-threatening TRD and 10 (21.7%) had combined TRRD. The mean (± SD) duration of decreased vision was 48.0 ± 58.2 weeks. The mean follow-up duration was 21 ± 13.2 months. Residual macular SRF was detected by optical coherence tomography in all eyes at 3 months and in 10 eyes (23.8%) at 12 months after surgery. Only 3 eyes (6.5%) had persistent SRF at final follow up. The mean time to resolution was 10.6 ± 4.1 months [range 6.0–23.0]. Thirteen eyes received additional intervention to address SRF. The mean CFT gradually improved until final follow-up (P-value < 0.001). The mean BCVA improved from 1.62 ± 0.88 LogMAR at presentation to 1.05 ± 0.76 LogMAR at final follow up. No statistically significant difference in final BCVA was found between eyes that had intervention and eyes that were observed (P value = 0.762). Conclusion: Persistent SRF after diabetic vitrectomy resolves slowly over time with gradual improvement in visual acuity. Additional drainage of persistent SRF may not be necessary
New constraints from U–Pb dating of detrital zircons on the palaeogeographic origin of metasediments in the Talea Ori, central Crete
No full textHigh-pressure low-temperature metamorphic sediments of the Phyllite–Quartzite unit sensu stricto and the Talea Ori group are investigated in the field, microstructurally and by U–Pb dating of detrital zircons to shed light on their palaeogeographic origin. Zircon age spectra with ages >450 Ma of the Phyllite–Quartzite unit sensu stricto indicate a palaeogeographic origin at the northern margin of East Gondwana. In contrast, the lower stratigraphic, siliciclastic formations of the Talea Ori group show a high number of well-rounded Cambrian to Early Carboniferous aged zircons and a Neoproterozoic zircon age spectrum with East Gondwana affinity. Based on the comparison of zircon age data, a possible distal sediment source is the Sakarya Zone at the southern active margin of Eurasia. To reconcile the zircon data with the geological observations we propose different alternative models, or a combination of these, including sediment transport from the Sakarya Zone and/or a westerly source towards the northern margin of Gondwana as well as terrane-displacement of the Sakarya Zone. Also, a palaeogeographic origin of the Talea Ori group at the southern active margin of Eurasia cannot be excluded. This alternative, however, would not be consistent with the usually assumed association of the Talea Ori group with the Plattenkalk unit characterized by a palaeogeographic origin at the northern margin of Gondwana
