N-Cinnamoyltetraketide Derivatives from the Leaves of Toussaintia orientalis
2015
Seven N-cinnamoyltetraketides (1−7), including the new Ztoussaintine E (2), toussaintine F (6), and toussaintine G (7), were isolated from the methanol extract of the leaves of Toussaintia orientalis using column chromatography and HPLC. The configurations of E-toussaintine E (1) and toussaintines A (3) and D (5) are revised based on single-crystal X-ray diffraction data from racemic crystals. Both the crude methanol extract and the isolated constituents exhibit antimycobacterial activities (MIC 83.3−107.7 μM) against the H37Rv strain of Mycobacterium tuberculosis. Compounds 1, 3, 4, and 5 are cytotoxic (ED50 15.3−105.7 μM) against the MDA-MB-231 triple negative aggressive breast cancer cel…
Sustainability in the restoration and management of the historic architecture in Palermo
2015
This research investigates the energy and environmental sustainability in the restoration and conservation of historic buildings. It focuses on the architectural heritage of Palermo, which can be a significant case study for the Mediterranean area. Its objective is to analyse the current energy performance of this historic architecture and its potential for energy improvement. Therefore, it aims at proposing a methodology to combine the enhancement of energy and environmental performances of the historic architecture of Palermo with the need of its material and aesthetic conservation, in the frame of the current regulations.
Rebuilt the space using stone or brick vaulted systems: catching the contemporary challenge of construction tradition
2019
In the recovery and restoration sites, as well as in the versatile word of university research about construction history, its not infrequent to study stereotomy for the re-proposal of stony or tiled vaulted systems, sometimes complex for their constitutive geometry, equipment, preliminary/subsidiary carpentry works. It represents a didactic study-key also in Engineering and Architecture Schools, through laboratories that teach to future designers a know-how that can be easily spent in their professional repercussions.
Innovative, Translucent and Multi-functional Components for the Building Envelope: technological and performance optimization
2017
The paper describes the actions aimed at the technology and performance optimization of an innovative, multi-functional building component made of precast and pre-stressed glass blocks useful for the construction of sustainable building envelopes able to reduce the energy consumption and to produce clean energy from the sun. The design optimization of different sub-components and the choice of the right materials for guaranteeing their good response in terms of mechanical resistance, thermal and acoustic insulation, light transmission, electricity production, integration with other components, dimensional coordination, are particularly described.
Architecture in iron in the city of XIX century Roof structures of theatres and covered markets in Palermo
2016
In post-unification Palermo, components manufactured abroad were usually used for complementary iron structures (greenhouses and skylights, projecting roofs, staircases…), whereas, for more demanding works, more weight was given to the contribution of producers with experience gained in the field of metal construction. Analysis is here carried out on the works of greatest importance, from the roofs of the two major theatres to the roofing of food market structures; the finest technicians were employed and a critical debate was triggered in the city with regard to formal, static and building aspects.
Strategies, Technologies and Novel Components for the Architectural Integration of Photovoltaics
2015
La ricerca riguarda l'integrazione architettonica del fotovoltaico (FV) per il retrofit energetico del patrimonio edilizio esistente e la costruzione di edifici a energia zero (ZEB). L'obiettivo è lo studio e la successiva definizione di strategie, tecnologie e componenti innovativi per l'involucro edilizio che integrino il fotovoltaico, con particolare attenzione verso le tecnologie fotovoltaiche di nuova generazione. Il lavoro si concentra anche sull'ottimizzazione energetica e sull'analisi delle prestazioni di un componente innovativo per il BIPV (Building Integrated Photovoltaics, letteralmente fotovoltaico integrato negli edifici) utile alla costruzione di involucri edilizi sostenibili…
The assessment of the reliability of an innovative 3rd generation solar cell integrated with “thermal belt” glass block
2017
Glass block is a building product widely used for the construction of translucent building façades and roofs. The need to adapt the product to the regulations in the field of energy saving and environmental sustainability has led to the design of innovative configurations, through the integration of different sub-components. These ones are able to improve its energy performance by means of the integration of a“thermal belt”, cold glued to the glass shells, which constitute the traditional glass block, and 3rd generation solar cells. This paper reports the first results of the experimental program designed to assess some durability components: inherent and critical reliability. <div id="g…
Yoga en España. Proceso de regulación profesional
2015
New approaches to spirituality go hand in hand with emerging physical, psychological and spiritual movements that have had a clear impact on many areas, and in particular on health and well-being. It is increasingly common to find nurses teaching yoga or doctors prescribing mindfulness. Use of socalled Complementary and Alternative Medicine (CAM) is becoming mainstream. Health centres, medical practices and even schools are offering a growing number of alternative therapies, resulting in the need for effective legal regulation of these activities, both in terms of professional recognition and training. In Spain, recent legislation represents a significant breakthrough in the regulation of y…
Artemisinin–Second Career as Anticancer Drug?
2015
Artemisinin represents a showcase example not only for the activity of medicinal herbs deriving from traditional chinese medicine, but for phytotherapy in general. Its isolation from Sweet Wormwood (qinhao, Artemisia annua L.) represents the starting point for an unprecedent success story in the treatment of malaria worldwide. Beyond the therapeutic value against Plasmodium parasites, it turned out in recent years that the bioactivity of artemisinin is not restricted to malaria. We and others found that this sesquiterpenoid also exerts profound anticancer activity in vitro and in vivo. Artemisinin-type drugs exert multi-factorial cellular and molecular actions in cancer cells. Ferrous iron …
Dictamen profesional sobre la fusión y escisión como extrategias alternativas en un grupo de sociedades
2021
This work is a professional, legal opinion which sets out two alternative strategies (merger by absorption and partial demerger) in order to bring together the different areas of activity of the various companies in a group of companies. The aim is to provide solutions to the questions raised by customers and, therefore, to set out clearly and simply the procedure to be followed in each of the strategies, weighing up the advantages and disadvantages from each of them
