The remember-know procedure is widely used to investigate recollection and familiarity in recognition memory, but almost all of the results obtained with that procedure can be readily accommodated by a unidimensional model based on signal-detection theory. The unidimensional model holds that remember judgments reflect strong memories (associated with high confidence, high accuracy, and fast rea...

Tiroid hastalıkları, gebelik esnasında kompleks hormonal değişiklikler nedeniyle yaygın olarak görülür. Fetal hidrops, düşük doğum ağırlığı, fetal distress ve nörofizyolojik gelişme geriliği açısından risklidir. 20 yaşında primigravid gebe hipotiroidizmle başvurdu ve bu esnada propiltiourasil (PTU) 3x1 kullanmaktaydı. Yapılan ultrasonografi (USG)’de hidrops fetalis görüldü ve bunun üzerine PTU ...
Mientras que los anillos incompletos asintomáticos pueden mantenerse bajo vigilancia9,10. La asociación de RTS y anillo vascular completo es poco frecuente. Es importante que ante la sospecha de anomalías cromosómicas los pacientes sean valorados por el cardiólogo pediatra para su diagnóstico. Las técnicas de imagen no invasivas son de ayuda para la delimitación de la anatomía precisa y la plan...
In recent decades cultivation of plants as a tool to manage the polluted areas by heavy metals has received an increased attention. In order to evaluate the possibility of using Four o’clock plant as a phytoremediator in soils polluted by Cu and Pb, an experiment was conducted using four levels of Cu and Pb (0, 200, 400, and 800 mg/kg) concentrations, as a factorial experiment based on a comple...
Backgrounds and Objectives : Heavy metals in dust can enter to the human body through ingestion andinhalation. They can pollute the water and soil resources via atmospheric precipitation and accumulate in the plants tissue and enter human body by water and food. The aim of this study was measurement of the heavy metals in wet and dry atmospheric precipitation and effects of pollution sources at...
Spin relaxation of conduction electrons in metals is significantly influenced by the Fermi surface topology. Electrons near Brillouin zone boundaries, special symmetry points, or accidental degeneracy lines have spin flip rates much higher than an average electron. A realistic calculation and analytical estimates show that these regions dominate the spin relaxation, explaining why polyvalent me...

Game-theoretic analysis is a well-established part of the toolkit of economic analysis. In crucial respects, however, game theory has failed to deliver on its original promise of generating sharp predictions of behavior in situations where neoclassical microeconomics has little to say. Experience has shown that in most situations, it is possible to tell a game-theoretic story to t almost any p...
Metals make up the bulk of the periodic table and range from the very light (e.g., beryllium) to the very heavy (e.g., the actinides). Metals are important constituents of life, drive economic activity and industry, but can also be a hazard to human health. The metals can be roughly divided into three groups. The first being those metals, such as iron and zinc, that are essential to human life ...
