In recent decades, significant efforts have been devoted to understanding and interpreting the link between ionospheric perturbations natural or anthropogenic phenomena, such as seismic activity, electrical geomagnetic storms, unidentified radio emissions. This is achieved through various methods among which also study of electromagnetic (EM) wave propagation in very low frequency (VLF, 3–30 kHz) (LF, 30–300 bands. These bands enable long-distance communication,...
Abstract The effects of applied current, testing time and microstructure on the electrochemical properties magnesium‐based sacrificial anodes in potable water were evaluated. Galvanostatic tests, potentiodynamic polarisation scanning electron microscopy (SEM) analyses used to determine anode efficiency, corrosion rate microstructures Mg‐anodes under study. contribution processes as mechanical material loss hydrogen evolution current wastage was investigated. effect different like those...
This paper aims to investigate the composition, surface, and microstructural characteristics, bioactivity of two commercially available pulp capping materials known as TheraCal LC BIO MTA+. The were prepared cylindrical samples assessed by X-ray diffraction (XRD) complex thermal analysis for mineralogical characterization, scanning electron microscopy (SEM) coupled with energy dispersive (EDX), Fourier-Transformed Infrared Spectroscopy (FT-IR), atomic force (AFM) surface characteristics. in...
Potentiodynamic polarisation and impedance measurements are used to examine the corrosion behaviour of some magnesium alloys, which were previously stressed in order establish effects mechanical deformation on electrochemical reactions at interface alloy/electrolyte. Due increasing demand for joint parts alloys there is a need perform localised machining. For this reason it interesting study both surface cross-section. DC und AC Polarisationsuntersuchung an Magnesiumlegierungen Einfluß der...
Amidst the prevalence of aggressive bacterial infections that can impact both oral and systemic health following various dental implant procedures, search for alternative, high-performing biocompatible materials has become a challenging pursuit. The need such investigations is increasing owing to fact toxicological risks cobalt–chromium (CoCr) alloys used in dentistry have part EU’s new Medical Devices Regulations establishing cobalt metal been classified as carcinogenic, genotoxic...
This work presents a case study of geoelectrical exploration understudied mud volcanoes in Romania, specifically the Pâclele Mici volcano from Buzău County. Using technique facilitated by distributed network V-FullWaver equipment, we present, to our knowledge, first deep 3D country. The findings indicate that while surveys such environments are met with important challenges terms soil conductivity, they nonetheless provide viable approach uncovering complex structures and processes...
In this paper, the microstructure, mechanical and anticorrosive properties of new CoCrNbMoZr alloy were studied in comparison with those commercial CoCrMo, Heraenium CE alloy. SEM XRD techniques used to evince morphology two alloys. Electrochemical linear potentiodynamic polarisation electrochemical impedance spectroscopy methods showed corrosion behaviour alloys artificial Carter‐Brugirard saliva different composition (doped NaF, pH = 8.21 undoped) values (3.83; 7.84; 9.11) simulating...
Large-scale radon monitoring is carried out due to the fact that it directly responsible for public health. European Directive 2013/59/EURATOM has been transposed into legislation of several countries and provides need long-term in homes workplaces by setting average annual reference level at 300 Bq/m3. At same time, a precursor factor, its emission being correlated with seismic volcanic activity. In this case, protection population ensured forecast similar meteorological one. The NIEP...
This paper is a review focused on the capability of graphene oxide (GO) coatings in preventing peri-implantitis. Firstly, establishes GO’s place frame carbonic materials and its role as composite material dentistry prevention bacterial infections sustaining osseointegration. Secondly, most relevant articles GO implant their associated shortcomings are presented emphasizing placed areas where more data needed. The main chapters devoted to relationship between biofilm formation implants...
The purpose of this study was to investigate the effect ultrasonic scaling on teeth restored with a light‐cured resin. Ultrasonic is very popular periodontal therapy among dentists, and used for removal dental plaque calculus in order reduce eliminate inflammation. Given fact that most devices are at high frequencies perform scaling, undesirable consequences, such as loss adhesion increase surface roughness, may occur have been resins. Electrochemical impedance spectroscopy ( EIS ) scanning...
Background & Aims: Even though Romania has one of the highest incidence and mortality in colorectal cancer (CRC) Europe, there is currently no organized screening program. We aimed to assess results our opportunistic CRC using colonoscopy.Methods: A single center retrospective study include all colonoscopies performed two 18 month periods (2007-2008 2012-2013) was designed. All asymptomatic individuals without a personal or family history adenoma with complete colonoscopy these time were...
We investigate the complex flow field around Vrancea slab in Romania, a steeply sinking seismogenic lithospheric block that experienced lateral tear-off and possible rotation. The is located beneath South-East Carpathians generates frequent seismicity despite its remote location from active collisional boundaries. analyse core-refracted shear wave (SKS) splitting recorded by permanent broadband seismic stations Romanian Seismic Network for periods up to 10 years, compare our results with...
