An Atypical Case of Taravana Syndrome in Mediterraneo

2010

Dysbaric accidents are usually referred to compressed air-supplied diving. Nonetheless, diving accidents are known to have occurred among breath-hold divers also and some cases are reported in medical literature. A male professional breath hold diver (57 year old) presented neurological disorders as dizziness, sensory numbness, blurred vision and left phronto-parietal pain after many dives to a 30-35 meters seawater depth. He went home after the regression of the symptoms and runned 8 Km the following morning. Pain, sensory numbness and dizziness occurred after running. He went by himself to the hospital where he had a grand mal seizure and lost consciousness. A magnetic resonance imaging o…

Inferential processes in readers with Down syndrome

2013

The aim of this work is to know if the source of the difficulty in making inferences, readers with Down syndrome, is in access to prior knowledge or constructing ideas from purely textual knowledge (based on Saldaña and Frith, 2002 for autism). Involved a sample of 20 students with Down syndrome and mild mental retardation (mean IQ = 60) and a control group of 20 children without cognitive deficits. They were matched as to their extent read metal age via Prueba de Evaluación del Retraso Lector (average 8 years). We created two experimental situations: a) subjects had to generate inferences based on physical knowledge, b) social inferences about knowledge. The ability to check and reaction t…

Abstract. Foreland fold-and-thrust belts (FTBs) record long-lived tectono-sedimentary activity, from passive margin sedimentation, flexuring, and further evolution into wedge accretion ahead of an advancing orogen. Therefore, dating fault activity is fundamental for plate movement reconstruction, resource exploration, and earthquake hazard assessment. Here, we report U–Pb ages of syn-tectonic calcite mineralizations from four thrusts and three tear faults sampled at the regional scale across the Jura fold-and-thrust belt in the northwestern Alpine foreland (eastern France). Three regional tectonic phases are recognized in the middle Eocene–Pliocene interval: (1) pre-orogenic faulting at 48.…

Abdominal Compartment Syndrome: diagnostic evaluation and possible treatment

2020

BACKGROUND: Abdominal compartment syndrome (ACS) is a clinical condition caused by an increase in intra-abdominal pressure. The incidence is variable, based on the type of patients taken into consideration, increasing exponentially in critical conditions, such as traumatized, burned patients in shock. The syndrome can also follow surgical procedures like transplantation of abdominal organs, for example configuring rare pictures such as RACS (post-transplant kidney syndrome). In most cases the symptoms are non-specific and varied according to the different etiology of the ACS, therefore the diagnosis may not be immediate. AIM: The aim of this work is to evaluate the best therapeutic approach…

Earth Construction: The Mechanical Properties of Adobe with the Addition of Laponite

2015

The contribution describes testing of compression strength, flexural strength and abrasion resistance of adobe made up of soil, water and sand (AS), soil, water, sand and straw (ASP), soil, water, sand and laponite nanoparticles (ASN). Embodied energy in materials presents an increasingly high percentage of the energy spent in the whole life cycle of a building. The same applies for carbon dioxide (CO2). Therefore, the development of new sustainable construction materi- als with lower embodied energy and lower CO2 emissions is needed. The use in construction of the brick made from soil, water and sand or straw, called adobe, boasts a millenary tradition and in recent years there has been re…

Testing the Acemoglu–Pischke model in Spain

2001

Abstract The Acemoglu–Pischke approach to training in imperfect labor markets predicts that wage compressions should shift incentives to invest in training from workers to firms. This will increase firm-sponsored general training when workers are unable to invest in training by themselves. Spain is on the top of the ranking of regulated labor markets. However, the training figures for Spain indicate a poor effect of highly compressed wage structure on firm-sponsored training.

Compression Methods for Microclimate Data Based on Linear Approximation of Sensor Data

2019

Edge computing is currently one of the main research topics in the field of Internet of Things. Edge computing requires lightweight and computationally simple algorithms for sensor data analytics. Sensing edge devices are often battery powered and have a wireless connection. In designing edge devices the energy efficiency needs to be taken into account. Pre-processing the data locally in the edge device reduces the amount of data and thus decreases the energy consumption of wireless data transmission. Sensor data compression algorithms presented in this paper are mainly based on data linearity. Microclimate data is near linear in short time window and thus simple linear approximation based …

Analysis and optimization against buckling of beams interacting with elastic foundation

2017

We consider an infinite continuous elastic beam that interacts with linearly elastic foundation and is under compression. The problem of the beam buckling is formulated and analyzed. Then the optimization of beam against buckling is investigated. As a design variable (control function) we take the parameters of cross-section distribution of the beam from the set of periodic functions and transform the original problem of optimization of infinite beam to the corresponding problem defined at the finite interval. All investigations are on the whole founded on the analytical variational approaches and the optimal solutions are studied as a function of problems parameters. peerReviewed

The use of results of spectral analysis of synchronous generator output voltage for technical diagnostics.

2006

The method of technical diagnostics of ship diesel engine-generator installations is offered. Spectral-power diagnostic parameters of the synchronous generator voltage and currents are used. The electric machine in this case is the multipurpose sensor of diagnostic parameters. On these parameters it is possible to judge quality of course of working processes in diesel engine cylinder, its technical condition. This method is applicable to piston compressor installations with the electric drive.

A Study on the Use of Combustion Phase Indicators for MBT Spark Timing on a Bi-Fuel Engine

2007

The performance of a spark ignition engine strongly depends on the phase of the combustion process with respect to piston motion, and hence on the spark advance; this fundamental parameter is actually controlled in open-loop by means of maps drawn up on the test bench and stored in the Electronic Control Unit (ECU). Bi-fuel engines (e.g. running either on gasoline or on natural gas) require a double mapping process in order to obtain a spark timing map for each of the fuels. This map based open-loop control however does not assure to run the engine always with the best spark timing, which can be influenced by many factors, like ambient condition of pressure, temperature and humidity, fuel p…
