Atmospheric trace elements in Ankara Turkey 1 factors affecting chemical composition of fine particles
Mustafa, Yatin; TUNCEL, SEMRA; Namik K, Aras; Ilhan, Olmez; Sezer, Aygun; Tuncel, Süleyman Gürdal (2000-01-01)
Fine and coarse aerosol samples were collected between February and June 1993, in Ankara, Turkey using a stack filter unit (SFU). Collected samples were analyzed for approximately 40 trace elements and major ions using a combination of instrumental neutron activation analysis, atomic absorption spectromerty and ion chromatography. Particle sizing characteristics of the SFU was tested against dichotomous sampler and the sampler was found to be a good alternative for more expensive particle sizing devices. Fo...
Net migration between different settlement types in Turkey, 1985-90
Hamamcı, Nihan Şahin; Gedik, Ayşe; Department of City and Regional Planning (2003)
In the past studies covering 1965-90, it is observed that net migration was from villages and district centers towards province centers. Although the net migration trend throughout the period was almost constant for the villages and the province centers, the role of the district centers changed in later periods. Previously, the district centers were transient settlements in terms of net migration with resultant almost zero net migration. However, in later years, they began to have net out-migration in signi...
Investigation of Turkey's carbon dioxide problem by numerical modeling
Can, Ali; Tokdemir, Turgut; Department of Engineering Sciences (2006)
CO2 emission is very important, because it is responsible for about 60% of the "Greenhouse Effect". The major objectives of this study were to prepare a CO2 emission inventory of Turkey based on districts and provinces by using the fuel consumption data with respect to its sources, to find the CO2 uptake rate of forests in Turkey based on provinces and districts, and to estimate the ground level concentration of CO2 across Turkey using U.S. EPA's ISCLT3 model for the preparation of ground level concentratio...
The Prognostic Value of Angiogenic Markers in Twin Pregnancies to Predict Delivery Due to Maternal Complications of Preeclampsia
Binder, Julia; Palmrich, Pilar; Pateisky, Petra; Kalafat, Erkan; Kussel, Lorenz; Zeisler, Harald; Munkhbaatar, March; Windsperger, Karin; Thilaganathan, Basky; Khalil, Asma (Ovid Technologies (Wolters Kluwer Health), 2020-07-01)
The sFlt-1 (soluble fms-like tyrosine kinase-1), PlGF (placental growth factor), and their ratio are useful for predicting delivery because of preeclampsia in singleton pregnancies. Evidence on the utility of sFlt-1/PlGF ratio in twin pregnancies is lacking. We aimed to evaluate the predictive value of sFlt-1/PlGF ratio for delivery because of preeclampsia in twins. A retrospective data analysis of 164 twin pregnancies with suspected preeclampsia was performed. The sFlt-1/PlGF ratio, which was known to clin...
Prognostic Value of Maternal Cardiovascular Hemodynamics in Women With Gestational Hypertension and Chronic Hypertension in Pregnancy
Kalafat, Erkan; Perry, Helen; Bowe, Sophie; Thilaganathan, Basky; Khalil, Asma (Ovid Technologies (Wolters Kluwer Health), 2020-08-01)
This study aimed to assess the prognostic value of cardiovascular assessment in women with gestational hypertension or chronic hypertension for the risk of preeclampsia and need for closer antenatal surveillance. This was a prospective study of pregnancies complicated by gestational hypertension or chronic hypertension presenting to St George's Hospital, between January 2015 and May 2018. A noninvasive ultrasonic cardiac output monitor was used to obtain cardiovascular variables of cardiac output (CO) and s...
