Metacognition and Self-regulated Learning in Predicting University Students' Academic Achievement in Turkey

The purpose of this study was to determine whether perceived levels of self-regulated learning and metacognition predicted the ultimate grade point average (GPA) attained by 206 female and 70 male college seniors (aged 21 to 27) finishing their elementary education teaching certification studies at a university in Turkey. Data regarding individual levels of metacognition were collected through the administration of the “Metacognitive Skills Inventory for Adults” (Schraw & Dennison, 1994) and translated to Turkish by Ozcan (2007). A separate scale authored by Turan (2009) was administered to the same set of participants to obtain levels of perceived self-regulated learning. Findings indicated that students’ self-regulated learning and metacognition total scores correlated with each other but neither scale was predictive of the students’ GPAs at a significant level in the hypothesized positive direction. Interestingly, self- regulated learning scores were significantly related to GPA but in a negative direction

Design of a specific MATLAB code for processing of standard tensile test data for sheet metal forming simulations

In order to obtain proper and sufficiently precise results from metal forming simulations, accurate material data should be input to the simulation software. One of the most important input for the simulation software is the flow curve yield curve of the material. Although there are many tests which could be performed in order to construct the flow curve such as standard tensile test, hydraulic bulge test, frictionless dome test, etc., standard tensile test is the simplest and cheapest technique despite of its technical restrictions. In this article, the studies regarding to the creation of a specific MatLab code for processing of tensile test data are presented. This specific MatLab code is capable of determining the constants of Hollomon’s, Ludwig’s, Swift’s and Voce’s hardening equations with their regression results, as well. By means of this code, the proper flow curve of any material and also the Lankford parameters could be obtained and the hardening equations which fits best to the experimental data could be determined

Possible role of GADD45γ methylation in diffuse large B-cell Lymphoma: Does it affect the progression and tissue involvement?

Objective: Diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma among adults and is characterized by heterogeneous clinical, immunophenotypic, and genetic features. Different mechanisms deregulating cell cycle and apoptosis play a role in the pathogenesis of DLBCL. Growth arrest DNA damage-inducible 45 (GADD45γ) is an important gene family involved in these mechanisms. The aims of this study are to determine the frequency of GADD45γ methylation, to evaluate the correlation between GADD45γ methylation and protein expression, and to investigate the relation between methylation status and clinicopathologic parameters in DLBCL tissues and reactive lymphoid node tissues from patients with reactive lymphoid hyperplasia. Materials and Methods: Thirty-six tissue samples of DLBCL and 40 nonmalignant reactive lymphoid node tissues were analyzed in this study. Methylation-sensitive high-resolution melting analysis was used for the determination of GADD45γ methylation status. The GADD45γ protein expression was determined by immunohistochemistry. Results: GADD45γ methylation was frequent (50.0%) in DLBCL. It was also significantly higher in advanced-stage tumors compared with early-stage (p=0.041). In contrast, unmethylated GADD45γ was associated with nodal involvement as the primary anatomical site (p=0.040). Conclusion: The results of this study show that, in contrast to solid tumors, the frequency of GADD45γ methylation is higher and this epigenetic alteration of GADD45γ may be associated with progression in DLBCL. In addition, nodal involvement is more likely to be present in patients with unmethylated GADD45γ. © 2015 Turkish Society of Hematology. All rights reserved

Kristal plastisite modellemesi ile ınconel 718 alaşımının işlenmesinde artık gerilmelerin doğru tahmini

Determination and assessment of residual stresses are crucial to prevent the failure of the components used in defense, aerospace and automotive industries. The objective of this study is to present a material method to accurately predict the residual stresses induced during machining of Inconel 718. Orthogonal cutting tests were performed at various cutting speeds and feeds, and the residual stresses after machining of Inconel 718 were characterized by X-ray diffraction. A viscoplastic self-consistent crystal plasticity model was developed to import the microstructural inputs of this superalloy into a commercially available finite element software (Deform 2D). In addition, same simulations were carried out with classical Johnson - Cook material model. The simulation and experimental results showed that the crystal plasticity based multi-scale and multi-axial material model significantly improved the prediction accuracy of machining induced residual stresses of Inconel 718 when compared to the existing model, and it can be used to minimize the surface defects and cost of production trials in machining of difficult-to-cut materials.Artık gerilmelerin belirlenmesi ve değerlendirilmesi, savunma, havacılık ve otomotiv endüstrilerinde kullanılan bileşenlerin arızalanmasını önlemede çok önemlidir. Bu çalışmanın amacı, Inconel 718'in işlenmesi sırasında oluşan artık gerilmeleri doğru bir şekilde tahmin etmek için bir malzeme modeli sunmaktır. Ortogonal talaşlı imalat testleri, çeşitli kesme ve ilerleme hızlarında gerçekleştirilerek, Inconel 718'in işlenmesinden sonraki artık gerilmeler, X-Ray ışın kırınımı ile karakterize edildi. Bu süper alaşımın mikroyapısal girdilerini ticari olarak temin edilebilen bir sonlu eleman yazılımına (Deform 2D) aktarmak için bir viskoplastik kendi içinde tutarlı kristal plastisite modeli geliştirildi. Ayrıca simülasyonlar klasik Johnson - Cook malzeme modeli ile aynı işleme parametrelerinde yapıldı. Bu çalışmada elde edilen simülasyon ve deneysel sonuçlar, kristal plastisite tabanlı çok ölçekli ve çok ölçekli malzeme modelinin, mevcut modele kıyasla Inconel 718'in işleme kaynaklı kalıntı gerilmelerinin tahmin doğruluğunu önemli ölçüde geliştirdiğini ve yüzey kusurlarını en aza indirmek için kullanılabileceğini göstermiştir. Geliştirilen bu model, kesilmesi zor malzemelerin işlenmesinde yüzey kusurlarını ve üretim denemelerinin maliyetini en aza indirmek için kullanılabilir
