Determination of type and ratio of superplasticizers in concrete production
(2007)
Concrete is the most commonly used construction material. The most significant properties of the concrete are the workability and compressive strength. The use of silica fume (SF) and super plasticizers (SP) in concrete ...
Setup times with a learning effect in flowshop scheduling problem
(2007)
Relevant to recent scheduling studies, setup times of jobs have generally been either neglected or considered in processing times. But, in some production systems the setup times may be so large that it can not be neglected ...
The bryophyte flora of Erdek, Bandirma, Manyas districts (Balikesir, Turkey)
(Asian Network for Scientific Information, 2007)
This study was carried out in Erdek, Bandirma and Manyas districts in Balikesir province in order to contribute to the bryophyte flora of northwest Turkey. In this study, 134 taxa (at species and infraspecific ranks) ...
The relationship between orthostatic differences in arterial blood pressure and autonomic tone: Gender variability
(2007)
Objectives: The differences in orthostatic blood pressure result from dynamic changes in the sympathovagal balance. We studied sex-related variations in autonomic tone regulation. Study design: The study included 237 ...
A new delay parameter for variable traffic flows at signalized intersections
(2007)
Estimation of delay at signalized intersections is a complex process and depends on a number of parameters, among which the degree of saturation (x = v/c) is the most important. This paper presents a new methodology for ...
A new method for extracting 3D solid models of objects using 2D technical drawings
(2007)
In this study, a new method called "3D-Space" have been developed to obtain 3D models of prismatic machine parts using 2D technical drawings. The algorithm basicaly works in the following manner: 3 basic views (i.e. top, ...
The karyotype of the wild boar Sus scrofa Linnaeus, 1758 in Turkey (Mammalia: Artiodactyla)
(2007)
This study is based on the karyological analyses of 4 Sus scrofa specimens obtained from Kirikkale province in 2003 and 2005. It is the first time that karyotypes of Turkish wild boar specimens were determined. The diploid ...
Embolization of high-flow craniofacial vascular malformations with onyx
(Amer Soc Neuroradiology, 2007)
BACKGROUND AND PURPOSE: Various techniques and materials have been used for the endovascular treatment of craniofacial high-flow arteriovenous vascular malformations, because their rarity precludes standardization of their ...
The role of nickel accumulation and epithelial cell proliferation in orthodontic treatment-induced gingival overgrowth
(Oxford Univ Press, 2007)
The aim of this study was to investigate the role of nickel in orthodontic treatment-induced gingival hyperplasia. The nickel concentration in gingival tissues with and without overgrowth, histopathology of gingival ...
