Optimizing Airport Runway Capacity and Sustainability through the Introduction of Rapid Exit Taxiways: A Case Study

This contribution arises from the need to respond to the increased air demand of an airport with a sustainable approach that minimizes the land consumption of new runways and reduces the fuel burn and emissions associated with aircraft. A new methodology is presented for designing Rapid Exit Taxiways (RETs), which is applied in improving the runway capacity of Costa Smeralda Airport following both the International Civil Aviation Organization (ICAO) and the Federal Aviation Administration (FAA) guidelines. The optimal scenario resulted from a combination of these guidelines. Using this new approach, it is demonstrated that, through both the introduction of RETs and their positioning along the runway, the hourly capacity of the runway can effectively be improved, consequently enhancing the airport capacity and reducing the runway occupancy time and thus fuel burn and emissions. Moreover, the presence of RETs increases the infrastructure resilience, since airplanes can clear the runway faster in case of flooding in risk areas

Influence of pulsed electromagnetic field as a pre-sowing treatment on germination, plant growth and yield of broad beans

Magnetic field is a variable abiotic factor, like temperature, air, soil and water that interacts with the living organisms. The use of different types of magnetic field at many different plant species is increasing and the results are promising. A two-year field experiment was established following a completely randomized design, to investigate the effect of pre-sowing magnetic field treatment for 0, 15, 30 and 45 min on three broad bean varieties. The obtained results showed that the treatment of seeds with pulsed electromagnetic field increased germination percentage, chlorophyll content, leaf area, photosynthetic rate, transpiration rate, stomatal conductance and dry weight. In general, the exposure of seeds for 15 min, gave the highest values compared to the control treatments for the three varieties used. A very interesting result is the fact that although there was an influence of the exposure of magnetic field on the dry weight of the plants, there was not a positive or a negative influence on the seed yield for both years. This means that magnetic field enhanced the vegetative development of the broad beans, but it had no effect on the reproductive development. The results indicate that magnetic field can be used in the cases that the productive direction of the cultivation of broad beans is for livestock forage and silage, as the pre-sowing treatment of seeds had a positive effect on plant dry weight. *** In press - Online First. Article has been peer reviewed, accepted for publication and published online without pagination.

O testamento da rainha D. Beatriz

As precárias condições de vida, a falta de imunidade às doenças e o proliferar das epidemias tornavam a morte uma realidade tão constante e presente no quotidiano da sociedade medieva que ela era aceite como inerente à própria natureza humana. No entanto, esta familiaridade não diminuiu o medo que a população tinha da morte. Porque ela é certa, mas incerta a sua hora, era necessário preparar o “saimento” deste Mundo. A forma como ocorria essa passagem podia abrir as portas da eternidade, ou seja, era através da morte preparada que o indivíduo tinha a esperança de conquistar o paraíso. A doutrina da Igreja defendia, por um lado, o fim dos prazeres terrenos e, por outro, sendo a salvação da alma o objectivo supremo de todos os homens, era importante que cada cristão reflectisse na sua passagem para a vida eterna. Deste modo, a prática de redacção do testamento vulgarizou-se, sobretudo a partir dos finais do século XIII1

'The greatest living critic': Christiana Herringham and the practise of connoisseurship

Christiana Herringham (1851–1929) was a founder and benefactor of the National Art Collections Fund in 1903. Her career as an artist and art writer is less well known. Herringham undertook early experimentation with tempera painting alongside her translation of Cennino Cennini’s (c.1370–c.1440) treatise on painting techniques. Herringham’s meticulous approach to understanding “medieval art methods” was a catalyst for the foundation of the Society of Painters in Tempera. Her writing for the art press, most notably for the Burlington Magazine where she was on the Consultative Committee, reveals her expertise on the technical aspects of connoisseurship. This article traces the development of Herringham’s “scientific” method and highlights her pivotal role in a series of interconnecting networks. Knowledge and understanding of techniques and materials gave her a particular authority, just at the point that art history as a discipline was developing. Herringham’s interventions point to the need for a re-evaluation of male-centered narratives about the formation of art history

May lamotrigine be an alternative to topiramate in the prevention of migraine with aura? Results of a retrospective study

Evidence suggests that lamotrigine could be effective in reducing aura frequency and duration. However, studies comparing lamotrigine to other, first-line prophylactic agents solely involving patients suffering from migraine with aura are still lacking. The aim of this study was to compare the efficacy of lamotrigine and topiramate for the preventive treatment of migraine with aura

Le criticità del post, il caso EXPO 2015

A pochissimo tempo dalla chiusura di Expo Milano 2015 vi è ancora un grosso interrogativo su ciò che avverrà nell’area dell’esposizione una volta conclusi i lavori di smantellamento dell’evento. L’incertezza e l’immobilità delle istituzioni, che tanto hanno spinto affinché la manifestazione riuscisse nelle sue fasi iniziali, certamente non contribuiscono a smorzare le perplessità crescenti. Se a quanto detto vengono sommati i numerosi scandali nelle fasi iniziali della manifestazione si può capire come le preoccupazioni per la riqualificazione dell’area Expo siano molte e giustificate. Queste si fondano sulla consapevolezza che il non aver previsto per tempo il destino dell’Esposizione sia stato un errore strategico per lo sviluppo futuro dell'area

Charakter wyspiarski turystyki: przykład Sycylii i Sardynii

Treść artykułu podzielona jest na 4 części, w których autorka omawia kolejno: — specyfikę turyzmu w autonomicznym regionie wyspiarskich Włoch, — sycylijski model turystyki, — sardyński model turystyki, — doświadczenia regionów wyspiarskich w turystyce. Sycylia i Sardynia — mimo położenia na trasie wielkich, śródziemnomorskich potoków turystycznych — pozostają ciągle na uboczu. Głównymi powodami są: dość trudna dostępność, wygórowane ceny, polityka faworyzująca turystykę luksusową etc
