Serum Levels of Alpha-Tocopherol, Vitamin C, Beta-Carotene, and Retinol in Malignant Pleural Mesothelioma
(Asian Pacific Organization Cancer Prevention, 2012)The aim of this study was to investigate the possible relationship between antioxidant vitamin levels and malignant pleural mesothelioma (MPM). For this purpose, we measured the serum levels of 4 antioxidant vitamins, ... -
Six Year Mortality Profile Of A Pediatric Intensive Care Unit: Association Between Out-Of-Hours And Mortality
(2019)Introduction. Recent improvements in pediatric intensive care units (PICUs) were achieved through trained personnel and better technology, leading to an increase in patient care, survival rates and good prognosis. Nevertheless ... -
Sneezing And Runny Nose: Should Allergy Testing Be Routinely Performed?
(Springer, 2013)The need for routine determination of rhinitis subtypes by allergy testing and the relevance between symptoms and allergy were evaluated. A retrospective study at a tertiary hospital, ENT clinic. One hundred and twenty-seven ... -
Solving Large Scale Systems Of Linear Equations With A Stabilized Lanczos-Type Algorithms Running On A Cloud Computing Platform
(Hacettepe Univ, Fac Sci, 2018)The Lanczos-type algorithms for Systems of Linear Equations (SLEs) are efficient but fragile. A number of ways to resolve this issue have been suggested. But, the problem is still not fully sorted, in our view. Here, we ... -
Some Imputation Methods For Missing Data In Sample Surveys
(Hacettepe Univ, Fac Sci, 2016)The present work suggests some imputation methods to deal with the problems of non-response in sample surveys. The imputation methods presented in this work lead to the precise estimation strategies of population mean. ... -
Subsymmetry and Asymmetry Models for Multiway Square Contingency Tables with Ordered Categories
(De Gruyter Open Ltd, 2016)This paper suggests several models that describe the symmetry and asymmetry structure of each subdimension for the multiway square contingency table with ordered categories. A classical three-way categorical example is ... -
The Comparative Analysis Of Urban Transport In Ankara By Gender And Age Groups
(2019)Today travel time by urban transport has varied as a result of developing urban facilities, land use pattern, development of transport infrastructure and alternative transport system options for communities. Different ... -
The Effect of Changing Scores for Multi-Way Tables with Open-Ended Ordered Categories
(Hacettepe Univ, Fac Sci, 2016)Log-linear models are used to analyze the contingency tables. If the variables are ordinal or interval, because the score values affect both the model significance and parameter estimates, selection of score values has ... -
The Exponentiated Kumaraswamy-Power Function Distribution
(Hacettepe Univ, Fac Sci, 2017)In this paper, the exponentiated Kumaraswamy-power function distribution is introduced. Some structural properties of the proposed distribution including the shapes of the density, hazard and quantile functions are explored. ... -
The Extended Odd Weibull-G Family: Properties And Applications
(2019)The Weibull distribution is one of the most popular and widely used model for failure time in life-testing and reliability theory. In this study, we introduce a new class of continuous distributions called the extended odd ... -
The Lindley Family Of Distributions: Properties And Applications
(Hacettepe Univ, Fac Sci, 2017)In this paper, we propose a new class of distributions called the Lindley generator with one extra parameter to generate many continuous distributions. The new distribution contains several distributions as sub-models, ... -
The Lindley Weibull Distribution: Properties And Applications
(Acad Brasileira De Ciencias, 2018)We introduce a new three-parameter lifetime model called the Lindley Weibull distribution, which accommodates unimodal and bathtub, and a broad variety of monotone failure rates. We provide a comprehensive account of some ... -
The Role Of Factor V Leiden In Adult Patients With Venous Thromboembolism: A Meta-Analysis Of Published Studies From Turkey
(Sage Publications Inc, 2012)Factor V Leiden (FVL) is the most common inherited risk factor for venous thromboembolism (VTE). The frequency of FVL in patients with VTE has been reported from different parts of Turkey. A meta-analysis was performed to ... -
Time Scale In Least Square Method
(Hindawi Publishing Corporation, 2014)Study of dynamic equations in time scale is a new area in mathematics. Time scale tries to build a bridge between real numbers and integers. Two derivatives in time scale have been introduced and called as delta and nabla ... -
Using Next-Generation Dna Sequence Data For Genetic Association Tests Based On Allele Counts With And Without Consideration Of Zero Inflation
(2016)The relationship between genetic variability and individual phenotypes is usually investigated by testing for association relying on called genotypes. Allele counts obtained from next-generation sequence data could be used ... -
Vascular Endothelial Growth Factor (Vegf)-C, Vegf-D, Vegfr-3 And D2-40 Expressions In Primary Breast Cancer: Association With Lymph Node Metastasis
(Wroclaw Medical Univ, 2017)Background. Two members of the vascular endothelial growth factor (VEGF) family, VEGF-C and -D, are known as lymphangiogenic growth factors and play an important role in tumor lymphangiogenesis via activation of the VEGF ... -
Weighted Standard Deviation Method For (X)Over-Bar And S Control Charts
(2019)A Shewhart chart based on normality assumption is not appropriate for skewed distributions since its Type-I error rate is inflated. This study presents (X) over bar and S control charts for monitoring the process variability ...
