Introduction. The system of assessment of students' performance needs to comprise certain psychometric characteristics, including in particular reliability and validity, so that it can be a highly objective source of knowledge of students' learning outcomes. Aim. Analysis of reliability and validity of the performance assessment system for Midwifery students who started a Bachelor's degree prog...

and multiferroic [ 2 ] materials. For instance, ferroelectric materials at morphotropic phase boundaries (MPB), where multiple structural phases with ferroelectric polarizations pointing in different crystallographic directions coexist, often display large piezoelectric coeffi cients. [ 3– 5 ] It is the ferroelectric distortions, which accompany the polarization rotation that leads to enhanceme...

For the usual st raight·line model, in whic h the independent variable ta kes on a fixed, kno wn se t of va lues, it is shown that the sample corre lation coeffi cie nt is distributed as Q with (n-2) degrees of freedom and noncentralit y O=({3 /CT) V~(Xi X)2. The Q variate has been defin ed and studied e lse· where by Hogben et al. It is noted that the square of the correlation coeffi cient is ...

Wind speed and optical stratifi cation porosity (OSP) were measured at various heights inside a coastal protective forest thinned to different stem densities to assess whether any characteristics of the wind profi le in the coastal protective forest could be predicted from OSP. OSP was defi ned as vertical distribution of the proportion of sky hemisphere not obscured by tree elements inside a f...

Imaging and spectroscopy are non-destructive techniques for determining fruit qualities. The qualities of table grapes (Vitis vinifera) such as soluble solids content (SSC), pH, fi rmness seedlessness key parameters. This research was focused on comparison between imaging in laboratory eld. results Partial least squares regression (PLSR) showed that the best coeffi cient determination (R2) pred...

Background: Reports on the aquaporin-4 immunoglobulin G (AQP4-IgG) status for cognitive performance and neuroimaging correlations are limited in neuromyelitis optica (NMO) and multiple sclerosis (MS) literature. Methods: Cognitive results of 19 MS and 15 NMO patients were compared with 47 agematched controls. Apparent diffusion coeffi cient (ADC) values were used to delineate gray matter and wh...

Today, effective management of information requires an in-depth study its internal organization. The structural organization affects the efficiency choosing a method for solving problem and qualitative presentation about subject area. Therefore, article proposes new semiotic approach to assessing structuredness in area, as well theoretical, practical, general logical methods studying process se...

cial in subgroups of inten sive care unit (ICU) patients, but may harm other sub groups. Th is harm may be due to hypoglycemic events. In avoiding hypoglycemia, an accurate bedside glucometry method is essential [1]. Bridges and colleagues therefore evaluated the accuracy of a continuous subcutaneous glucose monitoring system (CGMS) in critically ill children, and concluded that the system prov...

background and purpose : there has been no report in which preoperative evaluation of adc for prediction of post therapeutic outcome was presented. the aim of our study was to retrospectively evaluation the use of the apparent diffusion coefficient (adc) for the prediction of malignancy and the outcome of malignant astrocytic tumors. methods: we reviewed mri of 26 male and 14 female patients wi...
