Background: This research aims to improve the urban excavation safety by creating an uncertainty-aware, geospatial augmented reality (AR) to visualize and monitor the proximity between invisible utilities and digging implements. Excavation is the single largest cause of utility strikes. Utility strikes could be prevented if the excavator operator were able to “see” buried utilities and excavato...

despite multiple published studies reporting result of salvage regimens for relapsed and refractory hodgkin's lymphoma, there are no comparisons of different combinations.a total of 44 patients identified with refractory or relapsed hodgkin's lymphoma were considered eligible for this study. the patients were randomly divided into two groups of 22, one of which were treated with gdp regimen (ge...

background:   primary bone lymphoma or non-hodgkin lymphoma of bone is a rare disease. there are only a few case series of stage ie of this condition in medical literature. the aim of this study is to determine the rate of survival   for stage ie after combined modality treatment, the rate of local recurrence, and the results of limb salvage in cases   of local recurrence.     methods:   we col...

background: massive bone allograft is an option in cases of limb preservation and reconstruction after massive benign and malignant bone tumor resection. the purpose of this study was to analyze the outcome of these procedures at imam reza hospital, mashhad university of medical sciences. methods: in this study, 113 cases have been presented. eleven cases were excluded (patients has a traumatic...

One practical excavation support system is the inclined struts connected to adjacent buildings. This method is very common in small excavations, because of simplicity and minimum cost, when soil is cohesive and depth of excavation is less than stability depth (Hcr) but adjacent structures is at risk of damage due to weakness, old age or lack of proper skeleton frame. Although this method ...

The site BAF-5 is located on the summit of Resolution Island, Nunavut, just southeast of Baffin Island at 61 degrees 35'N and 60 degrees 40'W. The site was part of a North American military defense system established in the 1950s that became heavily contaminated with PCBs during and subsequent, its operational years. Remediation through excavation of the PCB contaminated soil at Resolution Isla...

OBJECTIVES To compare the micro-tensile bond strengths of two different adhesive systems (ABF (Clearfil Protect Bond), Kuraray Medical Inc., Tokyo, Japan) and Prime & Bond NT (PBNT, Dentsply, Konstanz, Germany) bonded to caries-affected dentine retained after chemo-mechanical caries removal using Carisolv gel, with that retained after excavation using conventional hand instrumentation. METHOD...

Myocardial salvage assessed by 99mTc-sestamibi scintigraphy is a marker of myocardial tissue reperfusion in patients with acute myocardial infarction. The prognostic value of myocardial salvage index in patients with acute myocardial infarction after reperfusion therapy has not, however, been investigated. Methods: We analyzed 765 patients with acute myocardial infarction randomized to treatmen...

UNLABELLED Myocardial salvage assessed by (99m)Tc-sestamibi scintigraphy is a marker of myocardial tissue reperfusion in patients with acute myocardial infarction. The prognostic value of myocardial salvage index in patients with acute myocardial infarction after reperfusion therapy has not, however, been investigated. METHODS We analyzed 765 patients with acute myocardial infarction randomiz...
