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, ...
Epidermal growth factor receptor (egfr) immunolocalization in the sialoadenectomized rat ovaries
(2004)
Intra-ovarian regulation of follicular maturation is modulate by various factors. Among these, Epidermal growth factor (EGF) is vital factor. Epidermal growth factor (EGF) have potent mitogenic effects on granulosa and ...
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, ...
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 ...
Statistical convergent topological sequence entropy maps of the circle
(MDPI AG, 2004)
A continuous map f of the interval is chaotic iff there is an increasing of nonnegative integers T such that the topological sequence entropy off relative to T, hT(f), is positive. On the other hand, for any increasing ...
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. ...
Comparative petrogenetic investigation of Composite Kaçkar Batholith granitoids in Eastern Pontide magmatic arc—Northern Turkey
(2004)
The Pontides are an east-west trending orogenic belt which is subdivided into west, middle and eastern sectors according to their different tectonostratigraphy. The Eastern Pontides are represented by west-east-trending ...
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, ...
