It is well known that in many particular systems, the upper bound on a certain time-varying delay that preserves the stability may be higher than the corresponding bound for the constant delay. Moreover, sometimes oscillating delays improve the performance (Michiels, W., Van Assche, V. & Niculescu, S. (2005) Stabilization of time-delay systems with a controlled time-varying delays and applicati...
In this paper we consider that dark energy could be described solely by a complex scalar field with Bose-Einstein condensate-like potential (denoted as CSFDE), is, self-interaction and mass term. particular, analyse solution which in fast oscillation regime at late-times behaves Cosmological Constant. Our proposal adequately describes the standard homogeneous flat Fridman dynamics, furthermore,...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
abstract objectives gradual increase length and complexity of utterance (gilcu) therapy method is a form of operant conditioning. this type of treatment is very precise and controlled that is done in 54 steps in 3 speech situations consisted of monologue, reading and conversation. this study aimed to examine the effects of gilcu treatment method on reduction of speech dysfluency of school-age...
Background Tertiary Lymphoid Structures (TLS) are highly organized ectopic lymphoid structures found in inflamed or tumor tissues, acting as sites of recruitment and immune activation. A high TLS density within the is commonly associated with an increased prognostic effect TILs improved disease free survival overall for patients. 1 However, existence conflicting studies suggest that multiple fe...
Amaç:
 Elastomerik zincirlerin klinik kullanımı sırasında birçok avantajlarının olmasının yanısıra aktivasyon kuvvetinin zamanla farkedilir bir şekilde azalması en büyük dezavantajlarından biridir. Bu çalışmanın amacı; farklı elastomerik zincirlerde oluşan kuvvet kaybındaki değişimlerin incelenmesidir.
 
 Gereç ve Yöntem:
 Çalışmamız, 5 zincir grubundan oluşmuştur; Grup 1: A...
Background and Objectives: Heart failure is more common in the elderly than in the general population. Among the non-drug treatments, the easiest and most comprehensible method is direct implementation of sports program. Due to high cost of hospital care for patients with heart failure and complications, this study examined the effects of walking as a form of rehabilitation program. The subject...
We address the inverse problem of cosmic large-scale structure reconstruction from a Bayesian perspective. For a linear data model, a number of known and novel reconstruction schemes, which differ in terms of the underlying signal prior, data likelihood, and numerical inverse extra-regularization schemes are derived and classified. The Bayesian methodology presented in this paper tries to unify...
The thermal decomposition and ignition of high-performance high explosives occur via a mechanism where the solid phase sublimes parent molecules decompose rapidly in gas to form unstable charged intermediates. These intermediates continue react final products release energy do work. We have observed that presence electromagnetic significantly reduces temperature common explosive, data suggest t...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
