Preliminary limnological assessment on the shallow lagoon lake Çernek (Samsun, Turkey): Plankton composition and in relation to physical and chemical variables
(2004)
Çernek Lake is one of the most valuable wetlands of Northern Turkey. The lake and the surrounding wetlands are characterized by a high degree of biodiversity with reference to the species and natural habitats, so it has ...
Histological examination of ovarium development of shemaya Chalcalburnus chalcoides living in Lake Tödürge (Sivas/Turkey)
(2004)
The process of oogenesis of C. chalcoides living in Lake Tödürge was histologically studied from monthly samples during April-November 2000. The process was divided into five stages (previtellogenic, cytoplasmic growth, ...
The Influence of Preparation Methods on the Swelling and Network Properties of Acrylamide Hydrogels with Crosslinkers
(Marcel Dekker Inc., 2004)
Using different types and concentrations of crosslinkers, acrylamide (AAm) hydrogels have been prepared with chemical initiation and gamma irradiation techniques. The effects of the preparation method, crosslinkers type ...
Single mode optical radiation distribution and reflectivity calculations in novel-hot electron light emission and lasing in semiconductor heterostructures VCSELs
(2004)
In this work, we calculate the power reflectivity in vertical cavity surface emitting lasers (VCSELs) using a new method. In VCSELs, the stop band of the reflectivity spectrum should exhibit a dip at the lasing wavelength, ...
Preliminary design of ruble mound breakwaters by using artificial neural networks [Taş Dolgu Dalgakiranlarin Yapay Sinir A?lari ile Ön Tasarimi]
(2004)
A neural network is an artificial intelligence technique used in complex systems. It is based on the simplified simulation of biological neurons in human brain. Van der Meer equations are utilized for the design of rubble ...
Geology and trona potential of the middle Miocene Gürün (Si?vas) basin, Central Anatolia, Turkey
(Northeastern Science Foundation Inc., 2004)
Gürün (Sivas) basin, extending along east-west direction, contains a volcano-sedimentary sequence of up to 1222 m thick. The middle Miocene sedimentary sequence rest with angular unconformity on the basement rocks, which ...
Trace- and rare-earth element geochemistry of the Karalar (Gazipaşa-Antalya) barite-galena deposits, southern Turkey
(2004)
The Karalar barite-galena deposits are typical examples of carbonate-hosted barite-galena deposits that occur widely in the central Taurides. Recent mining activity has been concentrated in the Büyük and Boyalik mine areas. ...
Measurement of the carrying angle of the elbow in 2,000 children at ages six and fourteen years [Alti ve on dört yaş grubundaki 2000 çocukta ölçülen dirsek taşima açisi degerleri.]
(2004)
OBJECTIVES: It is important to know the carrying angles of both elbows in the evaluation of deformities which may be seen after treatment of distal humerus fractures. This study was performed to determine the basal values ...
Bacteriology in patients with chronic sinusitis who have been medically and surgically treated
(2004)
Chronic sinusitis is a disease that afflicts a significant percentage of the population and causes considerable long-term morbidity. The common use of multiple broad-spectrum oral antibiotics and endoscopic sinus surgery ...
On the reliability of SPT-N value as an indication of consistency of clayey soils
(2004)
Investigation of the shear strength properties and consistency distributions of the clayey alluviual soils of the Niksar basin located at the right bank of the Kelkit River and evaluation of the shear strength of the clays, ...
