N-ACETYL-ASPARTATE ABNORMALITIES IN INTERNAL-TEMPORAL EPILEPTICUS FOCUS USING PROTON MAGNETIC-RESONANCE SPECTROSCOPY

1995

International audience; Abstract: The aim of this study was to characterize the neurochemical abnormalities related to N-acetyl-aspartate which is a neuronal marker, within an epilepticus focus located in the internal-temporal area, using proton magnetic resonance spectroscopy, Eleven patients,with a mono-hippocampal epilepticus focus on clinical and per-critical electroencephalographical criteria, were matched with II controls by age, sex and laterality. Proton spectroscopy of a volume of 8 cm(3) was performed within the ipsilateral and the contralateral internal-temporal area and within the 2 hippocampus of controls. Volumetry of the ipsilateral and the contralateral hippocampus and of th…

Sistemi di tariffe di cubatura per le fustaie di pino d'Aleppo, pino laricio e pino domestico della Sicilia

2009

Obiettivo del presente lavoro e la messa a punto di sistemi di tariffe validi per la cubatura delle masse legnose dei principali soprassuoli di conifere della Sicilia: in particolare, i sistemi proposti si basano sull’elaborazione delle serie di inquadramento delle relazioni ipsodiametriche per il pino domestico, il pino d’Aleppo e il pino laricio. Per ciascuna specie e stato studiato l’andamento della distribuzione dei valori ipsodiametrici, risultato ben rappresentato da una forma funzionale di tipo semilogaritmico utilizzabile come «curva guida» delle serie di inquadramento delle relazioni ipsodiametriche. Adottando l’inclinazione stimata in base alla curva guida e adattando le singole s…

Dynamic shakedown design of structures under repeated seismic loads

2013

The paper is devoted to the formulation of an optimal design (minimum volume) problem of elastic perfectly plastic structures subjected to suitable combinations of static (fixed) and dynamic (seismic) loads. The structure is constrained to simultaneously respect two different safety criteria; actually, it must exhibit an elastic shakedown behaviour for the combination of loads characterizing the serviceability conditions and it must prevent the instantaneous collapse for the highest expected load condition (combination of loads characterized by the presence of fixed loads and maximum expected intensity of seismic action). The shakedown limit behaviour for the optimal structure will be impos…

Integrated Administration of the Organizations Informational Resources

2007

Organizations grow and develop continuosly and information volume grows in the same rythm, which makes from improvement or changing the old counting systems an imperative. More and more companies, instead of continuing to invest in small applications choose integrated informational solutions, which are adapted to the user’s daily needsfrom, all decisional levels. Although apparently profitable from the costs point of view, small applications assure only the simple economical solutions between clients, partners, furnisors, and employees. For high business volume companies, this kind of applications become useless in a short time, fact that involves extra sustained investitions

Volume preserving mean curvature flows near strictly stable sets in flat torus

2021

In this paper we establish a new stability result for the smooth volume preserving mean curvature flow in flat torus $\mathbb T^n$ in low dimensions $n=3,4$. The result says roughly that if the initial set is near to a strictly stable set in $\mathbb T^n$ in $H^3$-sense, then the corresponding flow has infinite lifetime and converges exponentially fast to a translate of the strictly stable (critical) set in $W^{2,5}$-sense.

UV filters: From sunscreens to human body and the environment

2007

Recognition of the harmful effects of ultraviolet (UV) radiation on the skin has triggered development of organic chemicals (commonly referred as UV filters) that can absorb UV radiation and attenuate the negative effects of sunlight exposure. Depending on the properties and the intended degree of protection, a wide array of combinations is being marketed as delivering protection against most kinds of UV-induced skin damage. However, some UV filters have dermatological implications, so maximum applicable concentrations have been established. To monitor to what extent commercial products comply with the mandatory limits, several analytical methods have been used for their determination in co…

Low Tree Vigor, Free Palmette Training Form, and High Planting Density Increase Olive and Oil Yield Efficiency in Dry, Sloping Areas of Mediterranean…

2022

Exploiting biodiversity must be considered today an effective strategy to improve the sustainability of olive production systems. The evaluation of local cultivars, based on their vegetative and fruiting traits, along with an analysis of product quality, may contribute significantly to the development and diffusion of new olive-growing systems. The aim of this study was to evaluate growth, productivity, and olive oil quality of three Sicilian cultivars with different vigor/growth habit grown in four different combinations of training form and planting density. ‘Abunara’, ‘Calatina’, and ‘Nocellara del Belice’ olive trees were planted in four different int…

Characteristic Kα emission of electron cyclotron resonance ion source plasmas

2018

This thesis presents the results of an investigation of the volumetric Kα emission rate/inner shell ionization rate from an Electron Cyclotron Resonance Ion Source (ECRIS) plasma tuned predominantly for high charge state ion production. The experimental work include four complimentary studies covering the influence of a parametric sweep of the four source tune parameters i.e microwave power, neutral gas flow, biased disc voltage and magnetic field on the volumetric Kα emission rate, an investigation into the gas mixing effect, an investigation into the effectiveness of double-frequency heating mode and finally an investigation into microwave induced electron losses (relative and direct) from th…

Nordic Higher Education in Flux: System Evolution and Reform Trajectories

2019

AbstractThis chapter provides a brief description of how the four national systems included in this study—Denmark, Finland, Norway, and Sweden—are currently organised and structured. In doing so, it illuminates several specific features such as the types and sizes of the institutions, enrolment patterns, performance measures, and funding. In addition, the chapter gives a snapshot of how higher education systems have evolved historically by shedding light on policy dynamics from the late 1990s to 2013, the baseline period for the FINNUT comparative study, the research project that provides the basis for this edited volume. This is followed by a section describing the aim, methods, theoretica…
