Application of SINTACS method to the aquifers of Piana di Palermo, Siciliy,Italy

2004

Piana di Palermo is characterized by the presence of two different aquifers: one shallow, constituted by calcarenites and the other deep in fractured carbonates. The calcarenitic aquifer presents a low potential compared to the carbonatic aquifer. The chemistry of the water in both aquifers reflects water-rock interaction, seawater intrusion, ionic exchange etc. The application of SINTACS method showed that about 80% of the study area can be classified as of high to very high vulnerability. Piana di Palermo es caracterizada por la presencia de dos acuíferos diferentes: uno somero constituido por calcarenitas y otro profundo en rocas carbonatadas fracturadas. El acuífero calcarenítico presen…

Diagnosis and therapeutic management of primary headache in an emergency setting

2013

Introduction and aim: Much headachers are under or mis-diagnoses and data regarding the proportion of patients attending an emergency department (ED) because of headache are still few. We conducted a retrospective observational study in an ED with the following aims: (a) estimate the proportion of headache attending to an ED (b) to estimate and describe the therapeutic management of primary headache and (c) to assessment the exam most frequently requested. Materials and methods: We collected data regarding patients diagnosed with headache consecutively attending the ED of the University of Palermo between September 2011 and March 2012. The study was approved by the ethics committee. Results: Between the semester evaluated 25110 subjects were admitted to ED headache suffers were equal to 1.6 %. Of these 263 (63.1 %) were woman and 154 (36.9 %). Mean age was 44.2 (DS ± 18.4) years (p = 0.068).According to ED registry headache admission was as follow assigned: 76.5 % with a diagnosis of headache 22.8 % with a secondary headache 0.7 % with Trigeminal Autonomic Cephalgias (TACs). Among those with a primary headache about 36 % of patient did not received a pharmacological treatment. Monotherapy was prescribed less frequently than combination therapy (19.1 vs 44.5 %).In monotherapy the most frequent medication were NSAIDs (28.3 %) benzodiazepines (26.7 %) and dopamine antagonists (11.7 %). Among those with a primary headache a CT scan was performed in the 124 subjects and 111 (34.8 %) had a neurologist consultation. Discussion: Our data are in line with the one previously reported in literature. The most frequently medication in the Italian ED were NSAIDs benzodiazepines dopamine antagonists and steroids. Neverless our data unlikely can be compared to other study give a snapshot. We believe that much more can be done to improve treatment of primary headache in ED.Settore MED/26 - Neurologia

Families of rational solutions to the KPI equation of order 7 depending on 12 parameters

2017

International audience; We construct in this paper, rational solutions as a quotient of two determinants of order 2N = 14 and we obtain what we call solutions of order N = 7 to the Kadomtsev-Petviashvili equation (KPI) as a quotient of 2 polynomials of degree 112 in x, y and t depending on 12 parameters. The maximum of modulus of these solutions at order 7 is equal to 2(2N + 1)2= 450. We make the study of the patterns of their modulus in the plane (x, y) and their evolution according to time and parameters a1, a2, a3, a4, a5, a6, b1, b2, b3, b4, b5, b6. When all these parameters grow, triangle and ring structures are obtained.

Pseidoeksfoliatīvā sindroma un kataraktas izmeklējumu un operācijas rezultāti

2017

Ievads: Pseidoeksfoliatīvais sindroms ir ar vecumu saistīta sistēmiska saslimšana, kas noved pie ekstracelulārā materiāla izgulsnēšanās primāri acs struktūrās un sekundāri visā organismā – asinsvados, ādā, žultspūslī, nierēs, plaušās un sirdī. Pseidoeksfoliatīvā sindroma pacientiem kataraktas operācija saistās ar neskaitāmām komplikācijām un izaicinājumiem. Cinna saišu vājums un traucēta zīlītes dilatācija ir divi galvenie riska faktori samazinātam redzes asumam un ķirurģiskajām komplikācijām, tādēļ šī sindroma aktualitāte un diagnostikas nepieciešamība īpaši pieaugusi pēdējo desmit gadu laikā. Darba mērķis: Šī retrospektīvā pētījuma mērķis ir apkopot “Dr. Solomatina Acu rehabilitācijas un …

Rational solutions to the KdV equation depending on multi-parameters

2021

We construct multi-parametric rational solutions to the KdV equation. For this, we use solutions in terms of exponentials depending on several parameters and take a limit when one of these parameters goes to 0. Here we present degenerate rational solutions and give a result without the presence of a limit as a quotient of polynomials depending on 3N parameters. We give the explicit expressions of some of these rational solutions.
