Exact solutions for the nonlinear KPP equation by using the Riccati equation method combined with the G'/G - expansion method
The improved Riccati equation method combined with the improved - expansion method is an interesting approach to find more general exact solutions of the nonlinear evolution equations in mathematical physics. The objective of this article is to employ this method to construct exact solutions involving parameters of a nonlinear Kolmogorov-Petrovskii-Piskunov (KPP) equation. When these parameters are taken to be...

Effects of a Tabebuia avellanedae extract and lapachol on the labeling of blood constituents with technetium-99m
Tabebuia avellanedae extract has been used in folk medicine in the treatment of some clinical disorders. Lapachol is an active compound from this medicinal plant. The procedure of labeling of blood constituents with technetium-99m (99mTc) could be used as an in vitro assay to evaluate some properties of natural and synthetic drugs. The aim of this work was to evaluate the effect of a T. avellanedae extract and lapachol...

A hybrid multilevel text extraction algorithm in scene images
The textual pieces in scene images might often provide vital semantic data for visual content understanding, indexing and analysis; as a result, text extraction had become a significant research area in image processing and computer vision. In this paper, we propose a new hybrid multilevel algorithm to extract text in various scene images. The algorithm converts the Red – Green –Blue (RGB) image into...

Ultrastructural changes in the neuronal superior colliculus in the early stage of streptozotocin-induced diabetes mellitus in rats
The superior colliculus (SC) is a visuomotor center involved in the autonomic reflex adjustments of eye movements in response to visual stimuli. Diabetes mellitus (DM) is known to affect some visual pathway structures, but few studies have assessed the effects of diabetes on the SC. The aim of this study was to investigate the ultrastructural changes of SC neurons in the early period of streptozotocin (STZ)-induced...

Determination of the priority areas for the rehabilitation of degraded forest lands
Turkey has more than 21.67 million ha forest areas and 10.11 million ha of these forest areas are still degraded or highly degraded in 2012 year. These areas can only be transformed into a productive state with implementation of rehabilitation treatments. Determination of the priority of degraded forest areas for the rehabilitation is important issue and affected by many parameters in Turkey. Some important indicators...
