Adaptive arrangement of cyclic prefix length for MC-CDMA systems via multi-objective bat algorithm
(Springer London Ltd, 2018)
Multi-carrier multiplexing systems, used in high bit rate communication applications, are more affected by the time- or frequency-dependent fading effects incurring in the channel than the single-carrier systems. When the ...
Investigation of effects of MgO ratio on the surface quality and tool wear in turning Al-MgO composites
(Sage Publications Ltd, 2018)
In this study, specimens of Al-MgO metal matrix composites with reinforcement-volume ratios of 5%, 10% and 15% were produced using vacuum infiltration method. The produced specimens were then tested for machining on computer ...
Impacts Of High Voltage Electric Field (Hvef) Applications On Germination And Seedling Growth Of Seed (Triticum Aestivum L.) With Analysis By Fourier Transform Infrared (Ftir) Spectroscopy
(Parlar Scientific Publications (P S P), 2018)
Wheat is an important widely grown cereal that its grains used worldwide as a staple food. In this study, germination and seedling growth characteristics of grains of Triticum aestivum, the most widely grown species of the ...
Synthesis of amine-functionalized methacrylic acid-g-poly(ethylene terephthalate) fiber and its Congo red removal ability
(Springer, 2018)
The two kinds of amine-type adsorbents were synthesized by reacting hexamethylenediamine (HMDA) and tetraethylenepentamine (TEPA) with methacrylic acid-g-poly(ethylene terephthalate) (MAA-g-PET) fiber for the removal of ...
The Effect Of Different Environmental Conditions On Yield And Oil Rates Of Safflower (Carthamus Tinctorius L.)
(Parlar Scientific Publications (P S P), 2018)
Safflower (Carthamus tinctorius L.) is an important vegetable oil plant for human consumption and alternative bioenergy source. Also, this plant is used for the evaluation of fallow and marginal land areas in the world. ...
Effect of sintering on mechanical property of SiC/B4C reinforced aluminum
(Iop Publishing Ltd, 2019)
In this study, SiC (silicon carbide) and B4C (boron carbide) added Al 7075 based composites were prepared at 40%, 20% and 10% reinforcement ratios. Using powder metallurgy, composite sample with 9 different structures were ...
Removing of Congo red from aqueous solution by 2-hydroxyethyl methacrylate-g-poly(ethylene terephthalate) fibers
(Springer, 2019)
Grafting of 2-hydroxyethyl methacrylate (HEMA) on poly(ethylene terephthalate) (PET) fibers was carried out via free-radical polymerization technique using benzoyl peroxide as initiator. The obtained copolymers were examined ...
Investigation of cutting tool wear behaviors in machining of silicon carbide and magnesium oxide reinforced aluminum 2024 matrix composites
(Iop Publishing Ltd, 2019)
In this study, first Silicon Carbide (SiC) and Magnesium Oxide (MgO) powders of <= 105 micron particle size were mixed in equal amounts. Then, the powder mixture was reinforced by using vortex method in liquid Al2024 ...
Elimination of carcinogenic bromate ions from aqueous environment with 4-vinyl pyridine-g-poly(ethylene terephthalate) fibers
(Springer Heidelberg, 2019)
In this study, poly(ethylene terephthalate) fibers grafted with 4-vinyl pyridine (PET-g-4VP) was synthesized with using a radical polymerization method and its removal capacity for bromate ions in the aqueous solution was ...
Investigation of Heavy Metal Levels in Blood Samples of Three Cattle Breeds in Turkey
(Springer, 2019)
The aim of this study is to determine seasonal changes in the blood levels of some heavy metals in three Turkey-specific cattle breed: Native Land (NL), Grizzle Race (GR), and South Anatolian Red (SR). Blood samples were ...
