admitted to hospital for thunderclap headache, blurred vision and hypertension. Based on clinical manifestations, diagnostic work-up and follow-up, the authors diagnosed the case as posterior reversible encephalopathy syndrome (PRES) [1]. We agree that PRES should be considered in this case, while diff erential diagnosis such as subarachnoid hemorrhage (SAH) requires further investigation and e...

Objective: To study the relationships between serum vitamin D levels and plasma glucose or lipid levels in children and adolescents. Material & Methods: We conducted a prospective study on pediatric patients (age 2-18 years) of Adichunchanagiri Institute of Medical Sciences, BG Nagara from December 2011 to November 2012 with simultaneous measurement of 25-hydroxyvitamin D, fasting plasma glucos...

Richards, Lundqvist-Korf and Hossfeld growth functions were fi tted to age-height data of European chestnut (Castanea sativa Mill.) dominant trees on the northern slopes of Belasitsa mountain, Southwest Bulgaria. Th e model prediction performance was evaluated using quantitative as well as qualitative examinations. Goodness of fi t of each model was estimated by the coeffi cient of determinatio...

Background and Aim: Blood samples are used for the diagnosis of many diseases. Serum ferritin level is known to be a marker of anemia and iron overload disorders. However, blood collection is an invasive method. Saliva, as a bio-fluid, contains a va-riety of important components that are successfully used for assessment of body health. The use of saliva samples for ferritin evaluation can be re...

rhabdomyosarcoma is a common primary childhood malignancy that rarely metastasizes to the breast. we report a patient with a primary sinonasal rhabdomyosarcoma metastasizing to the breast, with no distant spread. we describe the imaging appearance of rhabdomyosarcoma on magnetic resonance imaging (mri), particularly on diffusion-weighted imaging (dwi) and apparent diffusion coefficient (adc) se...

We analyse the role of time-variation in coeffi cients and other sources of uncertainty in exchange rate forecasting regressions. Our techniques incorporate the notion that the relevant set of predictors and their corresponding weights, change over time. We find that predictive models which allow for sudden, rather than smooth, changes in coeffi cients significantly beat the random walk benchma...

A. Mahmutović, University of Zenica, Faculty of Metallurgy and Materials, Zenica, Bosna and Herzegovina This paper has r esearched into the infl uence of trace elements in st eel, combined with new casting pr ocesses, on the microstructure and micr o-segregation phenomenon in the case of struc tural steel. Thermocalc sof tware has been applied for calculation of steel phase. In the paper, close...

Atomic scale computer simulations, validated with experimental data, are used to uncover the factors responsible for defect-induced chemical expansion observed in non-stoichiometric oxides, exemplifi ed by CeO 2 and ZrO 2 . It is found that chemical expansion is the result of two competing processes: the formation of a vacancy (leading to a lattice contraction primarily due to electrostatic int...

Resumen Background: This study analyzed the psychometric properties of the Dyadic Adjustment Scale (DAS). Method: A sample of 1,180 participants, 590 adult heterosexual couples, from the Community of Madrid was examined via confi rmatory factor analysis. Results: The results indicate that the factor structure of this scale fi ts the hierarchical factor model proposed by the test authors. The in...

1 The Background Elementary courses in statistics introduce at an early stage the key assumption of “random sampling”. In more technical language, the data set is assumed to be identically and independently distributed (i.i.d.). In this framework a range of simple and elegant results can be derived, for example, that the variance of the mean of n observations is 1/n times the variance of the ob...
