Alternative gaseous fuels in port fuel injection spark ignition engines
(Elsevier Sci Ltd, 2011)
This paper investigates the use of alternative gaseous fuels in port fuel injection spark ignition engines via the Lotus engine simulation program. To this end, the engine model for a port fuel injection spark ignition ...
Pushover and nonlinear time history analysis evaluation of a RC building collapsed during the Van (Turkey) earthquake on October 23, 2011
(Springer, 2014)
The nonlinear seismic behavior of a collapsed reinforced concrete (RC) residential building in the city of Van in Turkey is investigated by the static pushover and nonlinear time history analyses. The selected RC structure ...
Some approximations of second order derivatives complex-valued functions
(Karaganda State Univ, 2018)
In this paper, we generalize the well known finite difference method to compute derivatives of real valued function to approximate of second order complex derivatives w(zz) and w((zz) over bar) for complex-valued function ...

Centaurea hypoleuca is one of the plants have been traditionally used in treatments of many diseases in folk medicine in Turkey. In the present study, ethanol, methanol, and ethyl acetate extracts of the plant's aerial ...
HEAVY METAL ANALYSIS BY MOSS SPECIES IN THE BLACK SEA REGION OF TURKEY
(Parlar Scientific Publications (P S P), 2013)
The heavy metal analysis of mosses in the Black Sea region of Turkey was determined using atomic absorption spectrometry method. The procedure was also validated by analysis of standard reference material (IAEA-336 Lichen). ...
Concentrations of elements in Lias coals from the eastern Black Sea Region, NE-Turkey
(Taylor & Francis Inc, 2016)
The element contents and organic matter-element relation between Lias-aged coals exposed in four fields in Gumushane and Bayburt were investigated. In general, fixed carbon and gross calorific values of the Edire and ...

Dacitic rocks that crop out around the Zigana Mountain (GumuAYhane) in the eastern Pontide (NE Turkey), are mainly composed of quartz, plagioclase, sanidine, amphibole, muscovite, and biotite as the main minerals. Zircon ...
Investigation of abrasion resistance of cement mortar with different pozzolanic compositions and subjected to sulfated medium
(Elsevier Sci Ltd, 2010)
The durability phenomenon for concrete, or cement mortar, has gained attention recently as one of the important mechanical properties. It can be described as concrete's resistance to the destructive influences of a medium ...
High Order Approximation of the Inverse Elliptic Problem with Dirichlet-Neumann Conditions
(Univ Nis, Fac Sci Math, 2014)
Inverse problem for the multidimensional elliptic equation with Dirichlet-Neumann conditions is considered. High order of accuracy difference schemes for the solution of inverse problem are presented. Stability, almost ...
