2. Aspettare a Ventimiglia. La frontiera italo-francese fra militarizzazione, crisi dell’accoglienza e solidarietà
Abstract This ethnography was conducted on the French-Italian border in Ventimiglia from 2019 until autumn 2021. The previous knowledge of the area has allowed understanding of how the management by the States of the Covid-19 pandemic has redefined the border device. The article starts with a description of how the border controls operate and continuously ch

3. Evaluation of a Graphite-Polyurethane Composite Electrode Modified with Copper Nanoparticles as an Amperometric Flow Detector in a Wall-Jet System for the Determination of Cysteine
A graphite-polyurethane composite electrode (GPUE) was modified by electrodeposition of copper nanoparticles (CuNP) followed by electrochemical treatment in NaOH (GPUE-CuNP), in order to prepare an amperometric sensor for the determination of cysteine (Cys). Cyclic votammograms of Cys solutions at GPUE-CuNP allowed the description of a sequence of electroche

6. Development of radiofrequency ablation device for surgical hepatocellular carcinoma treatment in agreement with Brazilian standards
Abstract Introduction Many studies have been carried out on the main causes of hepatocellular carcinoma (HCC) to identify suitable diagnosis methods and treatments to combat the disease. However, high equipment costs and the lack of hepatic-ablation technologies manufactured in Brazil encourage the design and implementation of a solution based on normative

7. Robot-assisted single port radical nephrectomy and cholecystectomy: description and technical aspects
ABSTRACT Introduction Robot-Assisted Single Site Radical Nephrectomy (RASS-RN) has been reported by surgeons in Europe and United States (1–3). To our best knowledge this video presents the first RASS-RN with concomitant cholecystectomy performed in Latin America. Case A 66 year-old renal transplant male due to chronic renal failure presented with an inc

8. Evaluation of Filler Effects on the Dynamic Mechanical Behavior of HTPB-Elastomer Used as Binder in Exemplary Composite Formulations
ABSTRACT: This study aims to evaluate the dynamic mechanical properties of a binder, used in composite propellants, with increasing amount of different solid fillers. Dynamic Mechanical Analysis (DMA) is performed to determine the region of glass-rubber transition temperature (Tg). Further parameters were obtained from the description of the loss factor curv

9. Developing novel one-step processes for obtaining food-grade O/W emulsions from pressurized fluid extracts: processes description, state of the art and perspectives
Abstract In this work, a novel on-line process for production of food-grade emulsions containing oily extracts, i.e. oil-in-water (O/W) emulsions, in only one step is presented. This process has been called ESFE, Emulsions from Supercritical Fluid Extraction. With this process, emulsions containing supercritical fluid extracts can be obtained directly from p

10. Galvanic vestibular stimulator for fMRI studies
INTRODUCTION: Areas of the brain that are associated with the vestibular system can be activated using galvanic vestibular stimulation. These areas can be studied through a combination of galvanic vestibular stimulation with functional magnetic resonance imaging (fMRI). In order to provide an appropriate sequence of galvanic stimulation synchronous with the

11. Vibration energy harvesting using piezoelectric transducer and non-controlled rectifiers circuits
Vibration energy harvesting with piezoelectric materials is of practical interest because of the demand for wireless sensing devices and low-power portable electronics without external power supply. For practical use of vibration energy harvester with piezoelectric materials, it is necessary to process the alternating current (AC) by using different rectifie
