Purpose of the work was to quantify the workloads and the neurologist’s commitment in ER, to verify the management of urgencies and appropriateness of neurological counseling requests. Neurologic emergencies are frequent in elderly patients and are associated with high morbidity and mortality. Due to the aging population, neurologic pathologies in emergency room (ER) are widely expected to increase. The role of the neurologist in this context is controversial. Methods: in 14 operative units of neurology a prospective collection of neurological evaluations in ER was carried out using boards of detection of the most frequent neurological clinical pictures seen in the course of a week. Data were collected from 738 cases. Attention was focused on cerebrovascular diseases (CVD), impairment of consciousness, epilepsy, headache, dizziness, head trauma and disorders of the peripheral nervous system (PNS). Achievements: neurological consultations were on average 5% of total accesses to ER. The most common pathology seen was ischemic stroke. After counseling most patients were discharged home. The CVD required the greatest commitment to the specialist. The usefulness of the specialized neurological “filter” has been confirmed in a non-simple operative context, aimed at optimizing the appropriateness of the hospitalization and the economy of the diagnostic path.

Simultaneous free convection above and below a uniformly heated horizontal plate has been widely investigated,both in the case of an isothermal surface,and of a uniformly heated surface,but always assuming only air as fluid(Pr=0.7).Nevertheless,there are works dealing with horizontal plates whose results show that the Nu dependence on Pr may not be simply expressed by a power law with the same exponent of the Gr *** it was considered useful to study the Prandtl number influence in the case of the isothermal horizontal *** show that,while for the lower surface of the strip the Nu dependence in Gr can be expressed by a power law with an exponent close to the Gr one,for the upper surface the exponent is sensibly *** equations related to the investigated situations are proposed.

Effect of template shape on metal nanoimprinting:a dislocation dynamics study

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2010年第10期11卷 722-726页

作者： lucia NICOLA Department of Materials Science and Engineering Delft University of Technology

Dislocation dynamics simulations are performed to investigate the effect of template shape on the nanoimprinting of metal layers. To this end, metal thin films are imprinted by a rigid template made of an array of equispaced indenters of various shapes, i.e., rectangular, wedge, and circular. The geometry of the indenters is chosen such that the contact area is approximately the same at the final imprinting depth. Results show that, for all template shapes, the final patterns strongly depend on the dislocation activity, and that each imprint differs from the neighboring ones. Large material pile ups appear between the imprints, such that polishing of the metal layer is suggested for application of the patterns in electronics. Rectangular indenters require the lowest imprinting force and achieve the deepest retained imprints.

PHYSICAL MODEL FOR THE ENGINEERING ANALYSISOF THE THERMOELASTICLTY OF SOLID BODIES

引用

Chinese Journal of Mechanical Engineering 2000年第3期13卷 165-170,177页

作者： lucia Umberto I.N.F.M.-Istituto Nazionale per la Fisica della Materia Nucl 意大利 Rivalta Sc I-15047

The thermal behaviour of the solids under elastic deformations is analysed in order to obtain a model which combines the molecular dynamics results with the global thermal behaviour of the solids under elastic transformations. The result obtained consists of the introduction of the thermal behaviour in the Parrinello-Rahman model, obtaining the thermal molecular dynamic model useful in the analysis of the thermoelastic behaviour of solids.

Smart superabsorbent alginate/carboxymethyl chitosan composite hydrogel beads as efficient biosorbents for methylene blue dye removal

引用

Journal of Materials Science & Technology 2023年第28期159卷 81-90页

作者： Zhen Zhang Noureddine Abidi lucian lucia Department of Forest Biomaterials NC State UniversityRaleighNCUSA Fiber and Biopolymer Research Institute Department of Plant and Soil ScienceTexas Tech UniversityLubbockTXUSA Department of Chemistry NC State UniversityRaleighNCUSA

The presence of toxic dyes in the aqueous medium has threatened environmental safety, and thereby re- moving them from wastewater in an efficient way is highly desired. Herein, the efficient biosorbents were successfully fabricated via a facile physical gelation process of sodium alginate (SA) and carboxymethyl chitosan (CMCTS) in an acidic aqueous solution. The as-prepared hydrogel beads not only displayed water superabsorbent properties and pH-responsive swelling characters but also exhibited excellent methylene blue (MB) adsorption capacity removal efficiency with experimental maximum MB adsorption capacity of 2518 and 1005 mg g -1 , which are comparable with most reported lignocellulosic and alginate-based hydrogels. The MB adsorption process fitted well in different kinetic and isotherm models and became more heterogeneous in concentrated MB solutions as verified by principal component analysis results. The adsorption mechanism was proposed, and the high dye absorbency was attributed to the strong electro- static forces between adsorbents and adsorbates. Our current study provides a promising and sustainable composite hydrogels platform targeted to dye decontamination.

Minimal Free Resolutions of Zero-dimensional Schemes in P1 ×P1

引用

Algebra Colloquium 2015年第1期22卷 97-108页

作者： Paola Bonacini lucia Marino Universita degli Studi di Catania ViMe A. Doria 6 95125 Catania Italy

Let X be a zero-dimensional scheme in p1 × p1. Then X has a minimal free resolution of length 2 if and only if X is ACM. In this paper we determine a class of reduced schemes whose resolutions, similarly to the ACM case, can be obtained by their Hilbert functions and depend only on their distributions of points in a grid of lines. Moreover, a minimal set of generators of the ideal of these schemes is given by curves split into the union of lines.

Telomere shortening as genetic risk factor of liver cirrhosis

引用

World Journal of Gastroenterology 2015年第2期21卷 379-383页

作者： lucia Carulli Department of Biomedical Metabolic and Neural SciencesUniversity of Modena and Reggio Emilia41126 ModenaItaly

Cirrhosis is the main complication of chronic liver disease, leads to progressive liver function impairment and is the main risk factor for the development of liver cancer. Liver failure at endstage cirrhosis is associated with increased mortality with liver transplantation as the only possible treatment at this stage. The pathogenesis of liver cirrhosis is not completely elucidated. Although the common factors leading to liver injury, such as viral hepatitis, alcohol consume or fatty liver disease can be identified in the majority of patients a small percentage of patients have no apparent risk factors. Moreover given the same risk factors, some patients progress to cirrhosis whereas others have a benign course, the reason remains unclear. In order to developnew diagnostic and therapeutic tools, it is s essential to understand the pathogenesis of cirrhosis. The identification of genetic risk factors associated with cirrhosis is one of the possible approach to achieve these goal. In the past years several studies have supported the role of telomere shortening and cirrhosis. In the recent year several studies on the relation between several single nucleotide polymorphism(SNPs) and cirrhosis have been published; it has been proposed also a cirrhosis risk score based on seven SNPs. Also epidemiological studies on identical twins and in different ethnic groups have been supporting the importance of the role of genetic risk factors. Finally in the very recent years it has been suggested that telomere shortening may represent a genetic risk factor for the development of cirrhosis.

Performance of a base isolator with shape memory alloy bars

引用

Earthquake Engineering and Engineering Vibration 2007年第4期6卷 401-408页

作者： Fabio Casciati lucia Faravelli Karim Hamdaoui Dept. of Structural Mechanics University of Pavia Pavia Italy

A new and innovative base isolation device is introduced in this paper based on extensive research carried out by the authors and their co-workers. A prototype of the device was built and experimentally tested on the shaking table. The new base isolation device consists of two disks, one vertical cylinder with an upper enlargement sustained by three horizontal cantilevers, and at least three inclined shape memory alloy （SMA） bars. The role of the SMA bars is to limit the relative motion between the base and the superstructure, to dissipate energy by their super-elastic constitutive law and to guarantee the re-centring of the device. To verify the expected performance, a prototype was built and tested under sinusoidal waves of displacement of increasing frequency with different amplitudes. It is shown that the main feature of the proposed base isolation device is that for cyclic loading, the super-elastic behavior of the alloy results in wide load-displacement loops, where a large amount of energy is dissipated.
