The colours of living organisms are produced by the differential absorption of light by pigments (e.g. carotenoids, melanins) and/or by the physical interactions of light with biological nanostructures, referred to as structural colours. Only two fundamental morphologies of non-iridescent nanostructures are known in feathers, and recent work has proposed that they self-assemble by intracellular...

A Ti-4Al-2Fe-3Cu (wt pct) alloy containing only low-cost alloying elements was fabricated by vacuum sintering a blend of TiH2, Al, Fe, and Cu powders at 1200 °C for 1 hour followed hot extrusion the same temperature. The as-extruded exhibited microstructure consisting mainly α/β lamellar colonies Ti2Cu as minor phase. average colony size lamella thickness were 118 12 µm, respectively, Fe predom...

Introduction: One of the complications anesthesia that can be encountered in thalassemia patients is cardiovascular instability caused by chronic anemia, cardiomyopathy, and endocrinopathy. In addition, with preeclampsia may also experience postoperative risks such as sustained hypertension, stroke, venous thromboembolism, seizures. This case report will discuss anesthetic management pregnant w...

In this paper, a new two-parameter window function - Raised semi-ellipse (RSE) is proposed. The obtained from fixed elliptical known as Semi-ellipse by raising the radius of minor axis parameter (β), and applied for design finite impulse response (FIR) digital filters. spectral parameters proposed are determined first compared with Kaiser – 2-parameter adjustable window. Subsequently, in its ap...

background: it has been reported that curcumin has anti inflammatory, antibacterial, anti tumor and analgesic properties. objective: the purpose of this study was to investigate the efficacy of curcumin in the treatment of minor aphthous stomatitis. methods: the study was a two week, randomized, double blind, placebo controlled of patients with minor aphthous. patients between 18 and 65 years o...

OBJECTIVE Recent work has shown that insulin stimulates its own secretion in insulin-sensitive humans, suggesting that insulin resistance in the β-cell could cause β-cell dysfunction. We have tested whether insulin exposure and insulin sensitivity modulate β-cell function in subjects with normal glucose tolerance (NGT) and whether they contribute to dysglycemia in impaired glucose regulation (I...

Background: Osteoporosis is one of the late complications of β-Thalassemia major. The pathogenesis of osteoporosis depends on different factors. Ineffectiveness of hematopoiesis is the major factor, and the other factors are defected by hormonal functions or biochemical parameters. Osteoclasts hyperactivity in thalassemia increases the serum receptor activator of nuclear factor Kappa B ligand (...
