Open AccessBottlenose dolphins (Tursiops truncatus) aggressive behavior towards other cetacean species in the western Mediterranean
Aggressive behavior of bottlenose dolphins (Tursiops truncatus) towards conspecifics is widely described, but they have also often been reported attacking and killing harbour porpoises (Phocoena phocoena) around ...

Open AccessDiagnostic benefits of adding EspC, EspF and Rv2348-B to the QuantiFERON Gold In-tube antigen combination
Interferon (IFN)-γ release assays (IGRAs) are used to diagnose latent tuberculosis (TB) infection (LTBI). To improve the accuracy of these tests, different approaches, such as alternative cytokine detection an...

Open AccessUse of IP-10 detection in dried plasma spots for latent tuberculosis infection diagnosis in contacts via mail
The aim of this study was to test the use of IP-10 detection in dried plasma from contact studies individuals (contacts of smear positive patients), by comparing it with IP-10 and IFN-γ detection in direct pla...

Ultrasound used to guarantee process control in the manufacture of components. A case study
In industry, there are several processes of production, and often, engineers put attention only on volume of production and few times in process control, then emerges the classic problem between the department...

Thermo-mechanical fatigue approach to predict tooling life in high temperature metal forming processes
In high temperature metal forming processes, strong mechanical and thermal cyclic loads coexist in the formed material and in the tooling. Such a phenomenon has a negative influence in the tool life cycle. The...

Numerical methodology to implement thermal effects in simulation of long stroke wear tribotests
The present paper reports the methodology used to numerically implement thermal effects in long stroke tribometer (LST) wear tests. Thermal effects correspond to the heating produced by friction between the pa...

Exposure to ionising radiations arising from the operation of nuclear installations and cancer mortality
World-wide controversy continues to surround the question of whether exposure to ionising radiations arising from nuclear power plants and radioactive fuel cycle facilities could increase the risk of cancer. T...

Open AccessAssociation between ERCC1 and XPA expression and polymorphisms and the response to cisplatin in testicular germ cell tumours
Cisplatin cures over 80% of testicular germ cell tumours (TGCTs), and nucleotide-excision repair (NER) modifies the sensitivity to cisplatin. We explored the association between NER proteins and their polymorp...

Deep Radiation Fog in a Wide Closed Valley: Study by Numerical Modeling and Remote Sensing
The Ebro river basin, in the northeastern part of the Iberian Peninsula in Europe, very often experiences radiation fog episodes in winter that can last for several days. The impact on human activities is high...

Study of Mesobeta Basin Flows by Remote Sensing
If no well-defined synoptic pressure gradients exist over a basin, flows can develop at a variety of scales, the main generators of circulations being spatial thermal differences. These dynamics are studied fo...

Wide binaries as a critical test of classical gravity
Modified gravity scenarios where a change of regime appears at acceleration scales a<a 0 have been proposed. Since for 1M ⊙ systems the acceleration drops below a ...

Heterogeneous Nocturnal Cooling in a Large Basin Under Very Stable Conditions
Large basins with relatively wide floors experience heterogeneous nocturnal cooling due to the diversity of the topography and the land use within the basin. Near mountain ranges the drainage flows prevail, bu...

A CFD comparative study of bubble break-up models in a turbulent multiphase jet
In this paper several bubble break-up models are compared. They have been implemented in the CFX-4.4 fluid dynamic commercial code, which uses the population balance equations for describing liquid/gas multi-p...

Study of the Probability Density Functions From a Large-Eddy Simulation for a Stably Stratified Boundary Layer
Turbulence in a non-strongly stably stratified large-eddy simulation (LES) case is studied through probability density functions (PDFs) to obtain additional information than that provided by classical LES aver...

Comparison of film condensation models in presence of non-condensable gases implemented in a CFD Code
Several film condensation models in presence of non-condensable gases are presented. They have been implemented in a CFD code and compared with experimental data. The aim was to improve the code for simulating...

Large-Eddy Simulations of the Stable Boundary Layer Using the Standard Kolmogorov Theory: Range of Applicability
Large-eddy simulations (LES) of the Stable Atmospheric Boundary Layer (SBL) are difficult because the turbulence is not isotropic for strong stratification and the Kolmogorov theory might be no longer valid. T...

Improving the Motion of Walking Machines by Autonomous Kinematic Calibration
Legged machines designed to walk on flat or irregular terrain do not need to possess great foot positioning accuracy in order to perform stable motion. However, the propulsion of the body—which normally follow...
