We describe recent observations and measurements realized with microstrip gas chambers (MSGCs) manufactured on boro-silicate glass coated with a thin layer of diamond-like carbon (DLC) having a surface resistivity around 4.1016Ω/❒. The role of the back-plane electrode configuration and potential in the detector performance has been studied. Even for this very high resistivity of the coatings, M...

purpose: to compare outcomes and recurrence rates of amniotic membrane transplantation (amt) plus intraoperative mitomycin c (mmc) and conjunctival rotational autograft (cra) plus intraoperative mmc in pterygium surgery methods: ninety-two eyes of 92 patients with primary nasal pterygium were enrolled. all patients were randomized to undergo either amt or cra. forty-three patients underwent amt...

conclusions both dexmedetomidine and esmolol can be used as agents to control hypotension in patients undergoing lumbar spine decompression and fixation surgery; the dexmedetomidine group, however, was associated with better intraoperative hemodynamic stability and reduced intraoperative analgesic and volatile anaesthetic requirement. results the study results showed that dexmedetomidine had lo...

Background: The touch preparation technique is an accurate and rapid method, and when used as intraoperative consultation examination technique it preserves a good amount of tissue for paraffin embedded sections. This study aimed at examining the accuracy of the touch preparation technique by comparing its diagnosis with that of final pathological diagnosis made by microscopic examinations. ...

Ten patients with prior spinal cord trauma were examined preoperatively by metrizamide computed tomography (CT) and were studied subsequently by intraoperative spinal sonography. On comparing intraoperative sonography with metrizamide CT, it was found that metrizamide CT tends to overestimate the size and number of posttraumatic cysts, that areas of myelomalacia on metrizamide CT correspond to ...

One of the biggest successes of the standard Big Bang cosmology is the prediction of the existence and black body nature of Cosmic Microwave Background (CMB). Observations and measurements of the CMB radiation by COBE (COsmic Background Explorer), WMAP (Wilkinson Microwave Anisotropy Probe) and Planck show an almost isotropic blackbody radiation with temperature TCMB = 2.726 ± 0.010 K (Mather e...

!%" The Vogar Fissure Swarm is one of four en-echelon fracture swarms that connect the !&" Reykjanes Ridge to the South Iceland Seismic Zone and the Western Volcanic Zone. !'" Occurring in an area of flat topography, this fissure swarm is clearly visible at the surface, !(" where it can be seen to affect recent postglacial lavas. Using remote sensing methods to !)" identify and measure all the ...

We introduce new OWL ontologies for observations and sampling features, based on the O&M conceptual model from OGC and ISO 19156. Previous efforts, (a) through the W3C SSN project, and (b) following ISO rules for conversion from UML, had dependencies on elaborate pre-existing ontologies and frameworks. The new ontologies, known as om-lite and sam-lite, remove such dependencies, and can therefor...
