The Role of Open Web Standards for Website Development Adhering to the One Web Vision
Serena Pastore
International Journal of Engineering and Technology , 2012,
Abstract: Information dissemination is essential for every organization that needs to increase its visibility. This is valid for educational or research institutes and businesses. Websites are actually the usual way to promote information considering that modern websites are web-based systems composed by several software layers implementing different functionalities. Nowadays, a plethora of web –based content management systems (WCMs), commercial and open-source, provide similar capabilities. The paper highlights the trends in modern website development considering actual open web standards and the particular features of the mobile framework. Approaches include responsive web design techniques and custom mobile sites. Web content should be accessible everywhere, anytime and with whatever devices, which means it should be visualized and processed in the same way regardless of the type of device used, the physical location of the user, and the communication network used at the time. Mobile users’ behavior has a great influence on website development, but open web standards should be adopted in web design to ensure a long-term growth towards the era of the Future Internet.
The Necessity of Semantic Technologies in Grid Discovery
Serena Pastore
Journal of Networks , 2008, DOI: 10.4304/jnw.3.4.1-9
Abstract: Service discovery and its automation are some of the key features that a large scale, open distributed system must provide so that clients and users may take advantage of shared resources. Most actual distributed systems are built with several middleware applications developed by using grid and web service technologies that allow an infrastructure to be implemented where users work as if they were in a local system. The paper, starting from the work done within grid projects in which the INAF Institute was involved, examines issues encountered and solutions proposed in the optics of sharing and thus using web resources such as web services in a specific grid system. By guaranteeing the efficient use of such resources, different discovery mechanisms, developed within grid and web service areas, have been evaluated. The results show the necessity of an appropriate resources’ description in terms of the information data model, protocol and search tools that could integrate semantic technologies required for automating the process. Enabling automatic discovery means both the enriching of description with one of the semantic languages that are in constant development (i.e. OWL-S, WSDL-S) and the availability of a mechanism able to interpret and process such information. This work aims at taking advantage of the improvement in semantic technologies to prove the efficacy of this approach in making use of applications that need a grid environment for their execution.
School-to-Work Transitions in Mongolia
Pastore, Francesco
The European Journal of Comparative Economics , 2009,
Abstract: Relatively little is known about the youth labour market in Mongolia. This paper addresses the issue by taking advantage of a recent ad hoc School to Work Transition Survey (SWTS) on young people aged 15-29 years carried out in 2006. After a period of sharp reduction in the 1990s, educational attainment is increasing, as compared to other countries in the area. Nonetheless, important constraints seem to affect the supply of education, especially in rural areas. In addition, as application of the new ILO school-to-work transition classification shows, the country is unable to provide young people with a sufficient number of decent jobs. This translates into high youth unemployment in urban areas and very low productivity jobs in rural areas. Mincerian estimates confirm that human capital is an important determinant of earnings in urban, but not in rural areas

Pairing properties and specific heat of the inner crust of a neutron star
A. Pastore
Physics , 2014, DOI: 10.1103/PhysRevC.91.015809
Abstract: We investigate the pairing properties at finite temperature of the Wigner-Seitz cells in the inner crust of a neutron star obtained with the recent Brussels-Montreal Skyrme functional BSk21. In particular we analyze the phenomena of persistence and reentrance of pairing correlations and their impact on the specific heat in the low-density region of the inner crust.
Pairing properties of the inner crust of neutron stars at finite temperature

Physics , 2014, DOI: 10.1051/epjconf/20146607019
Abstract: We investigate the thermal properties of the inner crust of a neutron star using the Hartree-Fock-Bogoliubov (HFB) formalism at finite temperature. We compare our results with the ones obtained solving the same equations, but within the BCS approximation. We observe that for the outermost regions of the inner crust, the two methods can show important differences, in particular when we use them to calculate the neutron specific heat of the system.
Superfluid properties of the inner crust of neutron stars. II. Wigner-Seitz cells at finite temperature
A. Pastore
Physics , 2012, DOI: 10.1103/PhysRevC.86.065802
Abstract: We investigate the superfluid properties of the inner crust of neutron stars at finite temperature for different pairing functionals. We generalize the formalism adopted in previous article to include the effect of the temperature to calculate the specific heat of each given Wigner-Seitz cell. The calculations are done for two pairing forces, Gogny D1 and $V_{\text{low-k}}$, with finite range and a density dependent contact interaction. We compare in such a way the effect of the pairing strength and of the range on the thermal properties of the inner crust.

Physics , 2015,
Abstract: The present understanding of nuclear electromagnetic properties including electromagnetic moments, form factors and transitions in nuclei with A $\le$ 10 is reviewed. Emphasis is on calculations based on nuclear Hamiltonians that include two- and three-nucleon realistic potentials, along with one- and two-body electromagnetic currents derived from a chiral effective field theory with pions and nucleons.

Abstract: the aim of this work is to obtain, purify and characterize biochemically a peroxidase from copaifera langsdorffii leaves (cop). cop was obtained by acetone precipitation followed by ion-exchange chromatography. purification yielded 3.5% of peroxidase with the purification factor of 46.86. the cop optimum ph is 6.0 and the temperature is 35 oc. cop was stable in the ph range of 4.5 to 9.3 and at temperatures below 50.0 oc. the apparent michaelis-menten constants (km) for guaiacol and h2o2 were 0.04 mm and 0.39 mm respectively. enzyme turnover was 0.075 s-1 for guaiacol and 0.28 s-1 for hydrogen peroxide. copaifera langsdorffii leaves showed to be a rich source of active peroxidase (cop) during the whole year. cop could replace hrp, the most used peroxidase, in analytical determinations and treatment of industrial effluents at low cost.
Redox Imbalance in T Cell-Mediated Skin Diseases
Saveria Pastore,Liudmila Korkina
Mediators of Inflammation , 2010, DOI: 10.1155/2010/861949
Abstract: The skin is permanently exposed to physical, chemical, and biological aggression by the environment. In addition, acute and chronic inflammatory events taking place in the skin are accompanied by abnormal release of pro-oxidative mediators. In this paper, we will briefly overview the homeostatic systems active in the skin to maintain the redox balance and also to counteract abnormal oxidative stress. We will concentrate on the evidence that a local and/or systemic redox dysregulation accompanies the chronic inflammatory disorder events associated to psoriasis, contact dermatitis, and atopic dermatitis. We will also discuss the fact that several well-established treatments for the therapy of chronic inflammatory skin disorders are based on the application of strong physical or chemical oxidants onto the skin, indicating that, in selected conditions, a further increase of the oxidative imbalance may lead to a beneficial outcome. 1. Introduction Epithelial cells are the outermost viable components of the skin and mucous membranes, and are the fundamental generators of highly specialized physicochemical barriers, that is, organized tissues that exist primarily to define and separate distinct compartments of the body with the aim to protect the host in its entirety and preserve single organ functions homeostatically. These protective functions are obviously maximal in the skin, the conjunctiva and the respiratory mucosa, since they define boundaries with direct contact with the environment. Normally, environmental microorganisms, toxins, and allergens are efficiently blocked from entry by the defence wall organized by layers of epithelial cells. In the viable portion of the epidermis, lipid plasma membranes, and highly specific membrane transport systems pose a formidable obstacle to transepithelial passages of most undesired molecules. In addition, intercellular junctional barrier connections (or tight junctions) create a continuum with the epithelial cell cytoskeleton, and are conserved even when epithelial cells divide or apoptose [1]. However, much of the physicochemical barrier function of human epidermis against the environment is provided by the cornified cell envelope (CE), a unique, highly lipophilic two-compartment system of corneocytes embedded in a lipid-enriched intercellular matrix [2]. Moving upward from the deepest layers of the epidermis, keratinocytes progressively differentiate and eventually become anucleated corneocytes, formed of cross-linked keratins enclosed within an insoluble matrix of proteins and surrounded by a ceramide-rich
