Growth, interleukin-2 production, and responsiveness to IL-2 in T4- positive T Lymphocyte populations from malignant cutaneous T cell lymphoma (Sezar…
1984
Abstract Functional analysis and surface phenotyping using monoclonal antibodies have revealed that malignant T lymphocyte populations in the peripheral blood of patients with Sezary's syndrome resemble the T helper cell populations from normal individuals. In this article we have studied the effects of the immunosuppressive drug cyclosporine A (CsA) on growth, interleukin-2 (IL-2) production, and the induction of IL-2 responsiveness of peripheral blood monocytes (PBMs) from five patients with Sezary's syndrome in vitro, using the lectin phytohemagglutinin (PHA) and the phorbol ester phorbol myristate acetate (PMA) as stimuli. The following results were obtained: PHA-induced cell proliferat…
Intangibles Disclosure Information on Internet by Multinational Corporations
2003
Rapid developments in information and communications technology, especially with regard to Internet, have caused a substantial impact on the delivery and dissemination of business information. Internet reporting is expected to bring significant benefits to reporting companies, including facilitating access to potential investors an other stakeholders, disseminating information more quickly, more widely and at less cost, providing a platform to integrate different technologies and reducing the cost of providing hard copy annual reports. In this paper, we have examined the extent and the way companies use Internet to provide information about their intangibles. We have established for the Sta…
Ionic Liquids: Media for Better Molecular Catalysis
2004
Ionic liquids (ILs) are more and more suggested as substitutes for traditional solvents in organic synthesis and catalysis. They are suitable candidates for the dissolution of ionic complexes. They can activate and retain them in a polar state: in fact, they act as sequestrands, opening the route to two-phase processes and easier catalyst recovery. This paper reviews authors' results with the development of new syntheses of ILs and applications in carbon–carbon bond formation (dimerisation of methyl acrylate) and redistribution (ring closing metathesis) reactions using ionic precatalysts.
Sustainable technologies for greenhouse systems
2020
The greenhouse cultivation system in European countries represents one of the most energy-intensive sectors in the agriculture and agro-industry sector. In this regard, renewable energies represent an innovative solution to reduce energy costs and environmental impacts. Both, the energy demands and the economic aspects are analyzed with regard to the main energy users, i.e.: heating and cooling systems, lighting and pumping for irrigation. This work considers the use of solar photovoltaic and thermal energy. The use of semi-closed greenhouses is also considered.
Diffusion versus recrystallization processes in Rb–Sr geochronology: Isotopic relics in eclogite facies rocks, Western Gneiss Region, Norway
2008
Abstract Rb–Sr and U–Pb isotopic data for granulite facies rocks, forming textural relics with respect to eclogite facies metamorphism in the Western Gneiss Region (WGR) of Norway, highlight the importance of textures and mineral reaction kinetics for the interpretation of geochronological data. Studied rocks from Bardsholmen, southern WGR, were subjected to granulite facies metamorphism at 955 ± 3 Ma (U–Pb, zircon). Later on, they experienced a subduction-related, kinetically stranded eclogitization ( T > 650 °C at ∼20 kbar) at 404 ± 2 Ma (Rb–Sr multimineral internal isochron data), followed by exhumation through amphibolite facies conditions. Full conversion of granulite to eclogite was …
Giovanni Giudici scrittore di racconti
2016
The essay inquires the narrative fiction of the Italian poet Giovanni Giudici with special regard to the two short stories "Sunny Scandinavia" and "Frau Doktor". A final comparison between Giudici's poetry and his narrative attempts concludes the essay.
Fatigue Design of Cruciform Joints including V-notch Effect at the Weld Toe
2014
Abstract The present paper proposes a new and more accurate fatigue life prediction model for fillet welded joints in steel subjected to constant amplitude loading. With the traditional fracture mechanics approach, the greatest difficulty when computing the fatigue life of a welded detail is to determine the initial crack size a0. The classical way to determine the stress intensity factor K (SIF) is by using the following formula Where σ is the applied stress, a is the crack size and g(a/T) the geometrical correction factor which has been determined by Gurney function or similar solutions. This approach is not accurate for short crack because of the singular V-notch behaviour close to the c…
A Note on added information in the RAS Procedure: reexamination of some evidence
2006
International audience; An example in Miernyk (1977) presented a rather counterintuitive result, namely that introducing accurate exogenous information into an RAS matrix estimating procedure could lead to an estimate that was worse than one generated by RAS using no exogenous information at all. This became an oft-cited black mark against RAS. Miller and Blair (1985) included a different (and small) illustration of the same possibility. It was recently pointed out by one of us that the Miller/Blair numerical results are wrong. For that reason, we decided to reexamine all the empirical evidence we could find on the subject. While figures in both Miernyk and Miller/Blair appear to be wrong, …
Condylar distances in hypermobile temporomandibular joints of patients with excessive mouth openings by using computed tomography
2014
Objectives: hypermobility in Temporomandibular joint (TMJ) can manifest higher range of motions in mandible. The aim of this study was to compare the position and distances of the head of condyle to glenoid fossa in TMJs of healthy individuals and patients with mild, moderate and severe TMJ hypermobility. Material and Methods: In this clinical study, 69 patients (between the ages of 22 to 42) with manifestation of joint hypermobility were included and Computed tomography were administered for both TMJs. The patients were divided into three groups based on their maximum mouth opening (MMO): (A) with MMO of 50-55 mm; (B) with MMO between 55 to 65 mm; and (C) with MMO >65 mm. Also, 15 healthy …
Reclutamiento y reclutas en la ciudad de Valencia (1717-1762)
2019
This research aims to analyze recruitment by quintas, Spanish word for recruitment levies by lot, in the city of Valencia and the townships included in its jurisdictional area. The analyzed period began in 1717 with the first levie decreted by king Philip V once the War of Spanish Succession was over. Applied this levie in the kingdom of Valencia, this was the first application of levies by lot. The closing year for the reported period up to 1762, whith the last levy made by king Charles III before the establishment of the annual periodicity for the recruitment process. Procedures with which human contingents claimed to the city of Valencia between the mentioned dates were organized and dis…
