The problem of a monopole mounted near the edge of a wedge or a vertex is considered. Three types of solutions-surface patch modeling, moment method/geometrical theory of diffraction (MM/GTD), and MM/eigenfunction-are presented, discussed, and compared with measurements. Results are in the form of input impedance and radiation patterns.
The microstructure with homogeneously distributed grains and less prior particle boundary (PPB) precipitates is always desired for powder metallurgy superalloys after hot isostatic pressing (HIPping). In this work, we studied the effects of HIPping parameters, temperature and pressure on the grain structure in PM superalloy FGH96, by means of scanning electron microscope (SEM), electron backsca...
Experimental results on hot deformation and dynamic structural processes of nickel based alloy Inconel 718 are reviewed. The focus is the analysis of dynamic precipitation processes which operate during hot deformation of these materials at elevated temperatures. Hot compression tests were performed on the solution treated precipitation hardenable nickel based superalloy Inconel 718 at 720-1150...
در این مقاله اثر صفحه زمین محدود آنتن بر الگوی تشعشعی آن تحلیل و بررسی شده است. الگوی تشعشعی چند نمونه آنتن تک قطبی سیمی ساده و یک آنتن تک قطبی خط پیچ دار تیغه ای شکل -که با المان های فشرده بارگذاری شده و پهنای باند 30-500 mhz را پوشش می دهد- با صفحه زمین های محدود با روش های تحلیلی تفرق هندسی (gtd) و جریان معادل لبه (eec) محاسبه شده اند. نتایج تحلیلی و شبیه سازی ها نشان می دهد که روش gtd در حا...
The work is devoted to a study of the microstructure and microhardness heat-resistant nickel-based superalloy 58Ni-Cr-Mo-B-Al-Cu after radial-shear rolling. rolling was carried out at temperature 925°С in three stages. It found that grain size γ-phase all stages decreased radial direction from center periphery 62 ± 2 2.5 0.2 µm. At third stage, grains reduced twice billet comparison initial sta...
The creep of the pre-strained superalloy N07080 is described in this work. pre-strain was achieved by warm rolling at 1050 oC.-The performed due to additional strengthening, i.e increasing hardness.-The drastically reduces rupture life compared standard heat treated superalloy.-The drastic reductionof result rapid cavity nucleation on stress concentration sites along primary grain boundaries su...
Circulating Tumor DNA: A Potential Novel Diagnostic Approach in Gestational Trophoblastic Neoplasia.
http://dx.doi.org/10.1016/j.ebiom.2016.01.013 2352-3964/Crown Copyright © 2016 Published by Elsevie Gestational trophoblastic diseases (GTD) are a group of disorders that originate from the trophoblast, which is the outer layer of the blastocyst that normally gives rise to the placenta and is the first tissue to differentiate from the developing embryos after implantation. The human chorionic g...
Masaharu Fukunaga, M.D. Department of Pathology, the Jikei University Daisan Hospital, Tokyo, Japan Hydatidiform moles With the increased use of ultrasound hydatidiform mole (HM) is being diagnosed at increasingly early stages of gestation. As villous edema is not fully developed, we cannot make a diagnosis of HM by macroscopic observation. Furthermore, microscopically the classic features of c...
