Abstract:

This study investigated the relationships between growth orientation, body height and depth on sampling sites. The survey was carried out during 2008 in the area of the island Mali Losinj. A total of 46 specimens of Halocynthia papillosa (Linnaeus, 1767) were analyzed. The growth orientation varied from 60? to 80? and body height was in the range of 20 mm to 110 mm. Pearson?s correlation coefficient shows the positive correlation between growth orientation and body height and the same correlation is determined between depth and body height. The Spearman rank correlation coefficient shows a mor

Abstract:

Own measurements examine the tensile strength of expanded polystyrene (EPS) depending on its bulk density. 30 samples were used to calculate the correlation coefficients between these two properties. In addition to the standard Pearson coefficient, we also calculate the rank correlation coefficients, Spearman´s and Kendall´s. By testing the hypotheses, we verify the correlation of the entire population. After finding a relatively close correlation (0.6 - 0.8), we apply different regression models, especially polynomial, but also exponential. We evaluate the properties of parameters in models,

Abstract:

Aim: We aimed to translate, cross-cultural adapt and validate the Marx activity rating scale (MARS) of the knee for Romanian patients with anterior cruciate ligament (ACL) injury. Method: The original English form was translated according to guidelines. We included patients with ACL injury undergoing reconstruction in two centers over 3 years. Subjects completed the translated MARS, International Knee Documentation Committee (IKDC) subjective knee form and EuroQol EQ5D. The examining physician completed the Tegner Lysholm scale as an objective evaluation. Re-testing was obtained after one mont

Abstract:

Genetic distance among six elite maize inbred lines was analyzed using SSR markers. Hybrid progeny obtained by crossing inbred lines according an incomplete diallel design was tested in field trials together with inbred lines per se.The objective of this study was to determine genetic distance of inbred maize lines and to examine if a significant correlation exist between the genetic distance of parental lines and the exhibited high parent heterosis (HPH) and specific combining abilities (SCA) for grain yield, ear lenght, kernel row numberand number of kernels per row.

Abstract:

Background/Aim. Quality of life related to health should be seen as a multidimensional concept that, in addition to the physical symptoms associated with a disease and treatment, should include physical, psychological and social functioning of a person. The primary objective of this study was to use the Serbian preliminary version of the Geriatric Oral Health Assessment Index (GOHAI) questionnaire in oder to examine the consistency, reliability and stability, as well as an introduction to the verification tool. Methods. The GOHAI questionnaire with 6-level Likert scale, translated into Serbian

Abstract:

Introduction: Preoperative evaluation of meningioma consistency is important because it will affect surgical procedures, surgical optimization, risk assessment, and patient management. The consistency of meningioma can be predicted by Apparent Diffusion Coefficient (ADC) value on MRI. ADC values are useful in quantitative tumor assessment based on diffusivity in the tumor. The objective of the study is to find out the correlation between ADC value and the pathology consistency of meningioma.Methods: A retrospective study was carried out using medical records at Dr. Soetomo General Hospital, Su

Abstract:

Beijing-Tianjin-Hebei is an area with insufficient per capita water resources. This study evaluates the current status and development trend of sustainable use of water resources in the region, and identifies specific factors influencing sustainable development so as to provide a theoretical basis and data support for the management of water resources in the Beijing-Tianjin-Hebei region. Applying the compound system of social, economic and ecological environment, this study established an evaluation index system. The evaluation index data is obtained through the relevant calculations based on

Abstract:

The research presented in this paper builds on previous work that lead to the definition of a family of semantic relatedness algorithms. These algorithms depend on a semantic graph and on a set of weights assigned to each type of arcs in the graph. The current objective of this research is to automatically tune the weights for a given graph in order to increase the proximity quality. The quality of a semantic relatedness method is usually measured against a benchmark data set. The results produced by a method are compared with those on the benchmark using a nonparametric measure of statistical
