La teoria della subalternità e il caso dei dalit in India
2008
Il subalterno è lo schiavo soddisfatto, il servo che idolatra il padrone, la donna che perpetua il modello del patriarca, il marginale che finisce per odiarsi: colui che ha interiorizzato la visione del mondo del dominante e crede legittimo il suo stato di minorità. Egli, subendo la cosiddetta violenza epistemica, si fa complice di chi rende angusta la sua esistenza: le fonti del suo istinto sono inquinate, alterate le ragioni dei suoi desideri ed egli vuole contro il proprio interesse. I subalterni sono il neo delle rivoluzioni e la falla di ogni progresso: quella porzione di popolazione che ha partecipato ma non ha compreso, le cui condizioni di vita non sono cambiate, subordinati prima a…
First trimester biochemical screening for Down's syndrome in singleton pregnancies conceived by assisted reproduction
2005
BACKGROUND: Serum biochemical markers [free betahCG (fbetahCG); pregnancy-associated plasma protein-A (PAPP-A)] used in first trimester Down's syndrome screening have not been fully investigated in pregnancies achieved by assisted reproduction techniques. We present data on pregnancies conceived by all types of assisted reproduction techniques, including pregnancies following ovum donation (OD) and a large sample by ICSI. METHODS: First trimester Down's syndrome screening was performed in 1054 normal singleton pregnancies: natural conception (n = 498), ovulation induction (OS, n = 97), IVF (n = 47), ICSI (n = 222) and OD (n = 190). RESULTS: No differences in maternal levels of fbetahCG and …
Harmonic behavior of trehalose-coated carbon-monoxy-myoglobin at high temperature.
1999
Abstract Embedding biostructures in saccharide glasses protects them against extreme dehydration and/or exposure to very high temperature. Among the saccharides, trehalose appears to be the most effective bioprotectant. In this paper we report on the low-frequency dynamics of carbon monoxy myoglobin in an extremely dry trehalose glass measured by neutron spectroscopy. Under these conditions, the mean square displacements and the density of state function are those of a harmonic solid, up to room temperature, in contrast to D 2 O-hydrated myoglobin, in which a dynamical transition to a nonharmonic regime has been observed at ∼180K (Doster et al., 1989. Nature. 337:754–756). The protective ef…
Subcutaneous Injection of Drugs: Literature Review of Factors Influencing Pain Sensation at the Injection Site.
2019
The subcutaneous administration route is widely used to administer different types of drugs given its high bioavailability and rapid onset of action. However, the sensation of pain at the injection site might reduce patient adherence. Apart from a direct effect of the drug itself, several factors can influence the sensation of pain: needle features, injection site, volume injected, injection speed, osmolality, viscosity and pH of formulation, as well as the kind of excipients employed, including buffers and preservatives. Short and thin needles, conveniently lubricated and with sharp tips, are generally used to minimize pain, although the anatomic injection site (abdomen versus thigh) also …
METHODOLOGIES FOR THE ENHANCEMENT AND THE PRESERVATION OF CULTURAL HERITAGE: THE CRITERIA TO DOCUMENTATION, DIFFUSION AND PREVENTION MEASURES
2014
Recovering our building heritage has a fundamental role regarding renewal process, since it constitutes one of the strategies for urban and territorial balance. The project of building recovery, therefore, mainly addresses the adjustment to new housing and urban needs, but it is obviously conditioned and/or “restricted” by the limitation of the building itself, in particular when the intrinsic characteristics must be preserved. The concept of “restriction” extends to its relation with the site, to the quality of the image, to the living conditions. Therefore any intervention of building recovery needs a philological study as a starting point, which consists of a critical interpretation of t…
Chapter 4</br>Will our children have the chance to do research on today’s digital books?
2016
In this chapter, I will first position my considerations about the sustainability of ebooks for future research in the context of book history; moreover, I will introduce basic concepts of (migration and emulation) as well as challenges to the long-term preservation of digital data in greater generality. After that and taking current research on past (printed) books as an analogy, I shall try to outline which kinds of (digital) material will be indispensable in the future to do research on today's digital book production: published digital materials and unique (digital) artefacts. Finally, I shall present the results of my exemplary studies to find out which precautions for the future avail…
Ceratium furcoides (Levander) Langhans in reservoirs at the Ebro watershed, Spain and Sao Paulo state, Brazil
2022
This study compares the morphological characteristics of the dinoflagellate Ceratium furcoides from three Ebro basin reser¬voirs (Spain) and from six reservoirs at São Paulo state (Brazil) with the aim to identify the distinct morphotypes of Ceratium furcoides in Spain and Brazil. We studied the physical and chemical variables to determine the trophic state of each reservoir. Unlike Ceratium hirundinella, Ceratium furcoides is not a frequent species within the plankton community at Ebro Basin reservoirs, however, this species has been responsible of one monospecific bloom at El Val reservoir. Nevertheless, both Ce-ratium species are considered invasive in South America. Ceratium furcoides h…

Metal oxide semiconductor sensors for monitoring of oxidative status evolution and sensory analysis of virgin olive oils with different phenolic cont…
2009
An electronic nose based on an array of six metal oxide semiconductor sensors was used to monitor the oxidative status of virgin olive oils (VOO) during storage. VOO samples, with and without phenolic compounds, were stored at 60 °C for 7 weeks. Once a week, absorbance at 232 and 270 nm, oxidized stability index, electronic nose, and sensory analysis were evaluated. Linear discriminant analysis models were constructed in order to classify samples according to oxidative levels. Based on these models, VOO samples with and without phenolic compounds at different storage times, divided in eight categories, were correctly classified also achieving a good correlation for sensory analysis. The met…
