Analyses of human-bear conflict in Yusufeli, Artvin, Turkey
Ambarlı, Hüseyin; Bilgin, Cemal Can; Department of Biology (2006)
Increasing levels of conflict between brown bears and rural people have been reported for Yusufeli (Artvin, Turkey). This study aimed to document the conflict, understand human attitudes and responses, determine local habitat use and daily activity patterns of bears, and evaluate available damage prevention techniques. The study was conducted within landscapes at different scales, ranging from a core area defined by a large valley system to the whole of Artvin Province. Data on close encounters, injuries an...
Monitoring durability of new concrete bridge decks
Aktan, Haluk M.; Yaman, İsmail Özgür; Staton, John F. (2001-08-03)
The ND durability monitoring procedure, which measures the soundness of field concrete, is based on the fundamental relationship between ultrasonic pulse velocity (UPV) and permeability of an elastic medium. An experimental study documented adequate sensitivity between UPV and concrete permeability. The durability monitoring procedure is based on a parameter developed as part of this study and called paste quality loss (PQL) which is computed from the probability density function parameters of ultrasonic pu...
Estimation of lining thickness around circular shafts
Ozturk, H; Unal, E (2001-06-22)
In this paper, the broken zone developing, around a circular mine shafts and lining pressure is estimated by integrating the results of numerical analysis and the "rock-load height" equation derived from empirical analysis. During numerical modelling studies, the computer program FLAC(2D) was utilized. In order to estimate equivalent Mohr failure Envelope from the generalised Hoek Brown failure criterion, a new FISH function was written within FLAC(2D). Parametric studies were carried out by considering mRM...
Experimental and numerical analysis of effect of curing time on mechanical properties of thin spray-on liners
Güner, Doğukan; Öztürk, Hasan; Department of Mining Engineering (2014)
This research study investigates the effect of curing time on elastic material properties (Young’s modulus, Poisson’s ratio) and tensile, compressive strength of thin spray on liners (TSL). TSLs are fast curing, comparatively thin (3-5mm) and widely used rock support system in mining and civil engineering excavations. They have advantages of low volume, rapid application and low operating cost. The major ingredients of current TSLs are divided as polyurethane/ polyurea or Portland cement based latex product...
An inventory of medium and large mammal fauna in pine forests of beypazari through camera trapping
Mengüllüoğlu, Deniz; Bilgin, Cemal Can; Department of Biology (2010)
Information about large mammals in Turkey usually does not go further than species lists or annual counts of particular species such as the wild goat. Camera trapping is a very useful technique to overcome this deficiency by gathering information about species presence, numbers, habitat use and behavior. Hence, a one year long camera trap study was conducted to demonstrate the diversity, activity, distribution patterns, habitat preferences and interspecific interactions of medium and large mammals in a 148 ...
