Charpy impact energy of functionally graded steels in the form of crack arrester configuration was investigated. Functionally graded steels which contain layers of ferrite, austenite, bainite and/or martensite could be produced by electroslag remelting. The results showed that notch tip position and the distances of notch with respect to the bainite and martensite layers significantly affect th...
Aim: The objective of the present study was to evaluate femoral notch type, width index (NWI), angle (NA) and α in patients with ACL injury compare nonathletic male population, using magnetic resonance imaging (MRI).Methods: 79 complete tear 80 as control group (aged 19-43 years) who had knee MRI were evaluated. NWI, NA measurements shape evaluated on axial fat-saturated proton-weighted sequenc...
a critical protection requirement for grid connected distributed generators (dg) is anti-islanding protection. in this paper, a new islanding detection method for any possible network loading is proposed based on utilizing and combining various system parameter indices. in order to secure the detection of islanding, eight intentional disturbances are imposed to the system under study in which t...
A compact CPW-fed ultra-wideband antenna with dual band-notch characteristic is presented. Two notched frequency bands are obtained by embedding two U-shaped slots in the radiation patch and a rectangle slot in the ground plane. The two notched bands can be controlled by adjusting the length of the responding slots. The proposed antenna is successfully simulated, fabricated and tested. Experime...
چکیده ملانومای متاستاتیک یکی از چالش برانگیزترین سرطان ها در حوزه درمان است. مطالعات اخیر نشان میدهند، سلول های بنیادی سرطان مسئول ایجاد متاستاز، مقاومت دارویی و بازگشت مجدد تومور هستند. این خصوصیات سلول های بنیادی به اختلال در مسیرهای پیام رسانی سلولی مانندnotch و wnt نسبت داده می شود و هدفگیری این مسیرها می تواند دستاورهای درمانی تازه ای را برای سرطان به همراه داشته باشد؛ اما تاکنون نقش مسیر...
Abstract Orthotropic steel decks (OSDs) are easily subjected to fatigue cracking under the cyclic vehicle loading, and arc notch between diaphragm U-rib is one of typical details. The strain values three measuring points at in a bridge were monitoring obtain stress time histories. Then, amplitudes damage degrees analysed. It was found that this detail tension–compression stress. maximum amplitu...
Notwithstanding remarkable progress in vascular network engineering, implanted bioengineered microvessels largely fail to form anastomoses with the host vasculature. Here, we demonstrate that implants containing assembled human vascular networks (A-Grafts) fail to engraft due to their inability to engage non-inflammatory host neutrophils upon implantation into mice. In contrast, unassembled vas...
Periodic noises are unwished and spurious signals that create repetitive pattern on images and decreased the visual quality. Firstly, this paper investigates various methods for reducing the effects of the periodic noise in digital images. Then an adaptive optimum notch filter is proposed. In the proposed method, the regions of noise frequencies are determined by analyzing the spectral of noisy...
Abstract Bamboo plants are one of the natural materials that often seen growing and quite fast; has been extensively researched for use as an alternative to steel reinforcement in concrete construction. is not only more accessible, it also cost effective beneficial environment. This study examines bonding strength bamboo concrete. Buluhpring from Gowa area which dried checked quality material u...
