Dark matter results from 225 live days of XENON100 data
2012
We report on a search for particle dark matter with the XENON100 experiment, operated at the Laboratori Nazionali del Gran Sasso (LNGS) for 13 months during 2011 and 2012. XENON100 features an ultra-low electromagnetic background of (5.3 \pm 0.6) \times 10^-3 events (kg day keVee)^-1 in the energy region of interest. A blind analysis of 224.6 live days \times 34 kg exposure has yielded no evidence for dark matter interactions. The two candidate events observed in the pre-defined nuclear recoil energy range of 6.6-30.5 keVnr are consistent with the background expectation of (1.0 \pm 0.2) events. A Profile Likelihood analysis using a 6.6-43.3 keVnr energy range sets the most stringent limit o…
Amphiphilic poly(hydroxyethylaspartamide) derivative-based micelles as drug delivery systems for ferulic acid
2008
Self-assembling micelles, potentially useful as drug delivery systems for ferulic acid (FA), were obtained in aqueous media from amphiphilic alpha,beta-poly(N-2-hydroxyethyl)-dl-aspartamide (PHEA) copolymers bearing at the polyamino acidic backbone both poly(ethyleneglycol) (2000 or 5000 Da) and hexadecylamine (C(16)) moieties, at a concentration of 7 x 10(- 3) and 4 x 10(- 3) g/l, respectively, with nanometre size and negative zeta potential. These micelles were able to entrap FA and to release it in a prolonged way in phosphate buffer solution at pH 7.4 and human plasma. These systems were also stable in storage conditions and have no cytotoxic effects on Caco-2, 16 HBE, HuDe and K562 cel…
Familial hypercholesterolæmia in children and adolescents: Gaining decades of life by optimizing detection and treatment
2015
Contains fulltext : 155263.pdf (Publisher’s version ) (Open Access) Familial hypercholesterolaemia (FH) is a common genetic cause of premature coronary heart disease (CHD). Globally, one baby is born with FH every minute. If diagnosed and treated early in childhood, individuals with FH can have normal life expectancy. This consensus paper aims to improve awareness of the need for early detection and management of FH children. Familial hypercholesterolaemia is diagnosed either on phenotypic criteria, i.e. an elevated low-density lipoprotein cholesterol (LDL-C) level plus a family history of elevated LDL-C, premature coronary artery disease and/or genetic diagnosis, or positive genetic testin…
I mercati coperti a Palermo. Architettura e tecnica nella costruzione in ferro tra Ottocento e Novecento
2020
The history of the construction and transformations of the covered iron markets in Palermo, between the nineteenth and twentieth centuries, is very interesting for scholars of historical construction techniques and systems and studies - in addition to the evolution, progress and rethinking - also the assumptions economic and social which made it possible to better organize trade within designed buildings. The essay offers some reflections on two covered markets designed by Giuseppe Damiani Almejda in Palermo and representative of that short and fervent Iron Age that was able to combine the needs of local entrepreneurs, who found a promising opportunity for growth in iron processing, and the…
Problems of the Constitutionalism of the Legal Norms related to the Restrictions of the Spread of Covid-19 infection
2022
Plašās diskusijas Latvijas sabiedrībā par Covid-19 infekcijas slimības ietekmē pieņemtajiem ierobežojumiem, to nozīmi un izpratni, kā arī Satversmes tiesā iesniegto pieteikumu skaits un ierosinātās lietas par iespējamo ar Covid-19 infekcijas slimības izplatības ierobežojumiem saistīto tiesību normu neatbilstību Satversmei norāda uz šī temata nozīmīgumu, kā arī uz to, ka par tiesību normās ietvertajiem ierobežojumiem nolūkā mazināt vīrusa slimības izplatību nav vienprātīgas nostājas. Pētījuma mērķis ir noskaidrot ar Covid-19 infekcijas slimības izplatības ierobežojumiem saistīto tiesību normu satversmības problēmas. Dažādu tiesību institūtu izpratne normatīvajos aktos un tiesību realitātē va…
CRIME AND PUNISHMENT: ADAM SMITH’S THEORY OF SENTIMENTAL LAW AND ECONOMICS
2020
For Adam Smith, a crime is not the result of a rational calculation of loss and gain but the consequence of envy and a vain desire to parade wealth to attract the approbation of others, combined with a natural systematic bias in overestimating the probability of success. Similarly, Smith does not conceive of legal sanctions as a rational deterrent but as deriving from the feeling of resentment. While the prevailing approach of the eighteenth century is a rational explanation of crime and a utilitarian use of punishment, Adam Smith instead builds his theory of criminal behavior and legal prosecution consistently on the sentiments. A well-functioning legal system is thus an unintended consequ…
Ozone-induced reductions in below-ground biomass: an anatomical approach in potato
2010
[EN] Potato plants were grown in open-top chambers under three ozone concentrations during two complete cropping seasons (93 and 77 d in 2004 and 2005, respectively). The effects of chronic exposure to ozone on leaf anatomy, cell ultrastructure and crop yield were studied. Severe cell damage was found, even at ambient ozone levels, mainly affecting the spongy parenchyma and areas near the stomata. Damage to the cell wall caused loss of cell contact, and loss of turgor pressure due to tonoplast disintegration, contributed to cell collapse. Phloem sieve plates were obstructed by callose accumulation, and damaged mesophyll cells increased their starch stores. Tuber yield fell sharply (24–44%),…
Adaptive Planning in-Service Inspections of Fatigued Structures in Damage Tolerance Situations via Observations of Crack Growth Process
2017
From an engineering standpoint the fatigue life of a fatigued structure consists of two periods: (i) crack initiation period, which starts with the first load cycle and ends when a technically detectable crack is presented, and (ii) crack propagation period, which starts with a technically detectable crack and ends when the remaining cross section can no longer withstand the loads applied and fails statically. The main aim of this paper is to present more accurate innovative stochastic fatigue model for adaptive planning inspections of fatigued structures in damage tolerance situations via observations of crack growth process during a crack propagation period. A new crack growth equation is…
Key competences and plurilingual education in the Valencian Region (Spain) : a curricular analysis of Primary Education
2020
The purpose of this work is to study the level of transversality of key competences in Primary Education in the Valencian Community. To this end, an analysis of the Decree 108/2014 cur-rently in effect will be carried out, along with determining the frequency with which each competence is worked on during this stage of education. The data obtained will be interpreted bearing in mind plurilingual programs and, more specifically, the basis of the methodological needs that are pursued in CLIL, the approach to teaching non-linguistic areas through a foreign language. Generally, the findings point to a lack of transversality in some of the competences, one of them being the linguistic competence…
On the nuclear response of the helium-cooled lithium lead test blanket module in ITER
2005
Abstract The helium-cooled lithium lead (HCLL) concept has been recently selected as one of the two European reference designs foreseen for the breeding blanket of a demonstration fusion reactor. In particular, within the framework of the research and development activities on this blanket line, an HCLL test blanket module (TBM) has to be designed and manufactured to be implemented in ITER. At the Department of Nuclear Engineering (DIN) of the University of Palermo, a research campaign has been carried out to investigate the nuclear response of HCLL-TBM inside ITER by a numerical approach based on the Monte Carlo method. A realistic 3D heterogeneous model of HCLL-TBM has been set-up and ins…
