Plasma Orexin-A and Ghrelin Levels in Patients with Chronic Obstructive Pulmonary Disease: Interaction with Nutritional Status and Body Composition
(2014)Orexin-A and ghrelin are two important polypeptides that stimulate food intake, however, there is a lack of sufficient information concerning their plasma levels in patients with chronic obstructive pulmonary disease (COPD). ... -
Prediction of Earthquake Hazard by Hidden Markov Model (Around Bilecik, Nw Turkey)
(Sciendo, 2014)Earthquakes are one of the most important natural hazards to be evaluated carefully in engineering projects, due to the severely damaging effects on human-life and human-made structures. The hazard of an earthquake is ... -
Robust Model Selection Criteria For Robust S And Lts Estimators
(Hacettepe Univ, Fac Sci, 2016)Outliers and multi-collinearity often have large influence in the model/variable selection process in linear regression analysis. To investigate this combined problem of multi-collinearity and outliers, we studied and ... -
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 ...
