in-situ testing techniques have proven to be successful in improving the speed and reliability of geotechnical investigations. one of the most common in-situ methods in engineering geology and site investigation is cone penetration test (cpt), which is mainly used for characterization of soils, as it is a robust, simple, fast, reliable and economic test that can provide continuous soundings of ...

Background and Objective:Determination of HER2 gene is crucial in breast carcinoma management and prognosis, as HER2 alterations are linked to a shorter disease-free period, overall survival and resistance to tamoxifen anti-estrogen therapy and other chemotherapy regimens, regardless of the nodal or hormone receptor status. This study aimed to...

knowledge of the orientation of horizontal in situ stresses is important to some areas of oil and gas field development plans. borehole breakouts observed in image logs and drilling-induced fractures are the main parameters for the determination of the stresses’ directions in situ. in this work, the orientations of borehole breakouts were investigated as a function of depth in oil wells a and b...

a literature review revealed that most of the empirical equations introduced for determination of the uniaxial compressive strength (ucs) of rocks based on the schmidt hammer rebound number (n) are not sufficiently reliable mostly due to the relatively low coefficient of correlations. this is attributed to the fact that in most cases one formula is used for all types of rocks, although...

background: flat urothelial lesions comprise a spectrum of morphologic changes ranging from reactive atypia to carcinoma in situ (cis). urothelial dysplasia and cis are associated with the recurrence and progression of urothelial carcinoma. distinguishing cis and dysplasia from reactive atypia based on histolopathogical features alone is often difficult. using different immunohistochemical mark...

the present study deals with development of a floating in-situ gel of the narrow absorption window drug baclofen. sodium alginate-based in-situ gelling systems were prepared by dissolving various concentrations of sodium alginate in deionized water, to which varying concentrations of drug and calcium bicarbonate were added. fourier transform infrared spectroscopy (ftir) and differential scannin...

purpose : to assess the outcomes of laser in situ keratomileusis (lasik) in patients with multiple sclerosis (ms) methods : 15 eyes of 8 patients with ms (2 men and 6 women) who referred for myopia treatment (with or without astigmatism) were undergone lasik. after refractive and visual acuity examinations, topographic and pachymetry screening, intraocular pressure (iop) measurement, biomicrosc...
