Development of efflorescence control methods of fly ash based foam geopolymers
(ICIVILTECH Afyonkarahisar, 2020)
Since the environmental impacts of carbon emissions due to the cement production have started to be discussed, an alternative material has been sought. Geopolymers are new generation materials which are good candidates to ...
Genetic variation among Turkish Maize (Zea mays L.) hybrids for tolerance to chilling stress
(Afyon Kocatepe Üniversitesi, 17.03.2020)
Maize (Zea mays L.) is a tropical crop and chilling temperatures (below 15 ºC) cause growth retardation and yield losses. The development of chilling-tolerant maize varieties is one of the goals of plant breeders growing ...
Modification of coupled Drinfel’d-Sokolov-Wilson equation and approximate solutions by optimal perturbation ıteration method
(Afyon Kocatepe Üniversitesi, 17.03.2020)
We try to find the semi-analytical approximate solutions for the system of partial differential equations by using a newly developed scheme. The optimal perturbation iteration method is introduced and then applied to a ...
Effect of polyolefin modified bitumen on Marshall stability
(Afyon Kocatepe Üniversitesi, 17.03.2020)
It is possible to improve the performance of the hot mix asphalt (HMA) by improving the properties of the materials (aggregate, bitumen) used in the HMA or by the addition of some special materials. In this study; polypropylene ...
Modification of pumice mineral and its use as additive for poly (lactic acid) based bio-composite materials
(Afyon Kocatepe Üniversitesi, 17.03.2020)
In this study, pumice (P) mineral was treated with silane in order to increase the compatibility for
poly(lactic acid) (PLA) which is a fully biodegradable polymer widely used in packaging and outdoor
applications. Neat ...
Genotoxic evaluation of bentazone and chloridazon herbicides in eisenia hortensis coelomocytes
(Afyon Kocatepe Üniversitesi, 31.12.2020)
In current study, genotoxic effects of Bentazone and Chloridazon herbicides on Eisenia hortensis species were investigated. The species of E. hortensis were collected from the natural habitats in Afyonkarahisar. Comet ...
Basic properties of statistical epi-convergence
(Afyon Kocatepe Üniversitesi, 31.12.2020)
In this paper, we give some basic properties in order to use statistical epi-convergence more efficiently in future studies. Such situations are studied: Uniform statistical convergence of sequence of functions, statistical ...
Combined effects of nano-sized calcite and fly ash on hydration and microstructural properties of mortars
(Afyon Kocatepe Üniversitesi, 31.12.2020)
Even though a reduction in pollution and CO2 emission can be achieved by the utilization of fly ash in cement-based materials, using a high volume of fly ash results in a reduction at the early age strength development ...
Derivation of dimensionless governing equations for axisymmetric ıncompressible turbulent flow heat transfer based on standard k-ϵ model
