The combination of geophysical data and geotechnical measurements may greatly improve the quality buildings under construction in civil engineering. A case study is presented here at a vacant building site. Initially, boreholes indicated complex geology. dipole–dipole configuration was selected for electrical resistivity tomography (ERT) implementation were processed interpreted by applying 2D 3D inversions. An electromagnetic survey also carried out different time periods successfully used...
The present paper cannot be considered, either as a rebuttal to any participant, or our overview of the debate. Its publication became necessary due fact that various participants raised additional questions, i.e., beyond points suggested by Varotsos et al. [1996]. We clarify these questions concern noise discrimination from electrical recordings, recent laboratory experiments which support emission precursors, and question on whether, not, retroactive adjustment VAN prediction parameters...
Abstract The three‐dimensional (3‐D) electron density representation of the ionosphere computed by assimilative IRI‐SIRMUP‐P (ISP) model was tested using IONORT (IONOspheric Ray‐Tracing), a software tool for calculating 3‐D ray‐tracing high‐frequency waves in ionospheric medium. A radio link established between Rome (41.8°N, 12.5°E) Italy, and Chania (35.7°N, 24.0°E) Greece, within ISP validity area, which oblique soundings are conducted. reference stations, from autoscaled fo F2 M (3000)F2...
Colonic lipomas are uncommon nonepithelial neoplasms that typically sessile, asymptomatic and incidentally found during endoscopy, surgery, or autopsy. We present a very rare case of 34-year-old female patient with symptomatic pedunculated cecal lipoma causing intermittent colo-colonic intussusception. Despite adequate imaging studies, definite preoperative diagnosis was not established the underwent exploratory laparotomy. Intraoperatively, intussusception cecum into ascending colon right...
The use of Mohr circles into magnetotelluric (MT) intepretation was introduced by Lilley (Lilley, 1976). By plotting Zxx-rotated versus Zxy-rotated (real and imaginary parts) important information on the conductivity structure is obtained. In this paper are employed to reveal directions polarisation electric field. Furthermore, following procedure for circle analysis suggested: Zxx -rotated Zyx-rotated (instead Zxy-rotated) principal axes system i.e., strike angle, regional 2D can be...
This letter investigates the possible coalition of time intervals and patterns in seismic activity during preparation process consecutive sizeable events (i.e., <i xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">M</i> <sub xmlns:xlink="http://www.w3.org/1999/xlink">S</sub> ges 5.9). During periods low-level activity, stress processes crust accumulate energy at seismogenic area, while larger act as a decongesting mechanism that releases considerable...
This letter presents the development and application of prediction-based adaptive filters incorporated with neuro-fuzzy technology for emergence detection weak electrotelluric potential anomalies appearing upon recordings Earth's electric field. Electric earthquake precursors (EEPs) are considered to be related forthcoming seismic events and, in many cases, hidden field background. Their can further complicated by probable appearance severe transient fluctuations induced mainly magnetic...
One of the complications laparoscopic cholecystectomy for gallstone disease that seems to exceed traditional open method is gallbladder perforation and spillage. Its incidence can occur in up 40% patients, most cases its course uneventful. However few an abdominal abscess develop, which may lead significant morbidity. Rarely formation due spilled lost gallstones retroperitoneal space. We herein report case a female patient who presented with clinical symptoms sepsis six months following...
The design, programming and implementation of a cost effective wireless structural health monitoring system (wSHMs) is presented, able to monitor the seismic and/or man-made acceleration in buildings. This actually operates as sensor network exploiting internet connections that commonly exist, aiming buildings being installed. Key-feature wSHMs it can be implemented Wide Area Network mode cover many remote structures buildings, on metropolitan scale. Acceleration data send, real time, from...
Abstract. In the present work, installation and technology applied for operation of Hellenic Seismological Network Crete (HSNC), located in front Arc, are presented. The topology, communication modes (wire satellite) along with data collection processing methodologies leads to a new seismological infrastructure South Aegean, one most seismically active regions Europe.
