Bu çalışmada, mekanik alaşımlama yöntemiyle üretilen alüminyum matrisli kompozitlerin aşınma performansı incelenmiştir. Tepki Yüzey Metodolojisi (TYM) Merkezi Birleşik Tasarım (MBT) kullanılarak belirli sürtünme katsayına bağlı olarak parametreleri optimize edilmeye çalışılmıştır. Farklı takviye miktarlarıyla (%6 ve %12) kompozit malzemelerin testleri farklı yük (5 N, 10 N 20 N) kayma hızlarınd...

IL-23 is a heterodimeric cytokine comprising a p19 subunit associated with the IL-12/23p40 subunit. Like IL-12, IL-23 is expressed predominantly by activated dendritic cells (DCs) and phagocytic cells, and both cytokines induce IFN-gamma secretion by T cells. The induction of experimental autoimmune encephalitis, the animal model of multiple sclerosis (MS), occurs in mice lacking IL-12, but not...

BACKGROUND Although previous studies have helped define the natural history of Duchenne muscular dystrophy (DMD)-associated cardiomyopathy, the myocardial pathobiology associated with functional impairment in DMD is not yet known.The objective of this study was to assess the distribution of transverse relaxation time (T2) in the left ventricle (LV) of DMD patients, and to determine the associat...

Background The aim of this study is to determine the predictive value of ultrasonography for results of local steroid injection in patients with carpal tunnel syndrome (CTS). Materials and Methods This prospective cohort study was conducted during a 1-year period in outpatient clinics of rehabilitation and physical medicine including 35 patients with moderate and severe CTS who receive ultras...

States and districts have embraced the goals of standards-based reform, but they have interpreted the rather broad objectives in their own unique ways. Merely setting the mark may not be enough to ensure adequate progress in our nation’s schools, Ms. Goertz warns. Comments Copyright Phi Delta Kappa International.

Cloud computing is a significant alternative in today’s educational perspective. The technology gives the students and teachers the opportunity to quickly access various application platforms and resources through the web pages on-demand. Unfortunately, not all educational institutions often have an ability to take full advantages of the newest information technology. The paper analyzes possibi...

In this work, we present the Text Conditioned Auxiliary Classifier Generative Adversarial Network, (TAC-GAN) a text to image Generative Adversarial Network (GAN) for synthesizing images from their text descriptions. Former approaches have tried to condition the generative process on the textual data; but allying it to the usage of class information, known to diversify the generated samples and ...

We propose testing for business cycle first-moment asymmetries in Markov-switching autoregressive (MS-AR) models. We derive the parametric restrictions on MS-AR models that rule out types of asymmetries such as deepness, steepness, and sharpness, and set out a testing procedure based on Wald statistics which have standard asymptotics. For a two-regime model, such as that popularised by Hamilton...
