Chirality and helicity of linearly-polarised Laguerre-Gaussian beams of small beam waists
(Elsevıer, 2021)The chirality and helicity of a linearly polarised Laguerre-Gaussian (LG) beam are examined. Such a type of light possesses a large longitudinal field amplitude when it is created with a sufficiently small beam waist and ... -
Change of electrical resistivity during phase transitions in NiMnSn-based shape memory alloy
The electrical conductivity is an important behavior of shape memory alloys. It is known that such alloys exhibit different electrical characteristics during phase transformation. In this study, Ni((50-x))Mn39Sn(11)Ta(x) ... -
Effects of water quality on the species richness and population distribution of waterbirds in Ahlat marshes, Turkey
(Sprınger, 2021)This study aims to evaluate the effect of water quality on species richness and population distribution of waterbirds in the Ahlat Marshes. Water quality values of temperature, pH level, dissolved oxygen total dissolved ... -
Comparison of Scour Properties of Classical and Trapezoidal Labyrinth Weirs
Free overfall structures might affect the structural safety of weirs. Thus, it is essential to minimize local scour in the downstream pool to ensure structural safety. In the present study, triangular, trapezoidal, and ... -
The design and development of a diesel engine electromechanical EGR cooling system based on machine learning-genetic algorithm prediction models to reduce emission and fuel consumption
Data-driven modelling techniques have recently been used in the development of engine design and control systems for defining the engine in-cylinder complex combustion process. The aim of this investigation is to improve ... -
Analysis of Dry Wear, Microstructure and Thermodynamic Parameters of CuAlTa Bulk Material
(Sprınger Indıa, 2021)The microstructural properties and thermodynamic parameters before and after abrasion were examined for a bulk Cu86Al10Ta4 (%wt.) shape memory alloy produced by the arc-melting method. From the XRD and SEM-EDX microstructural ... -
Novel gas measurement based on pressure triggered release cycles for biochemical methane potential tests
(Walter De Gruyter Gmbh, 2021)This study aims to present a novel gas counter and to demonstrate its suitability for biochemical methane potential tests. In this system, the gas to be measured is collected in a chamber enclosed with two one-way solenoid ... -
Assessment of radioactivity and heavy metal contents in surface water samples from Van Lake, Turkey
(Sprınger Heıdelberg, 2021)The aim of this study was to determine the natural radioactivity levels of surface water samples obtained from Van Lake in spring and autumn seasons. For this purpose, the gross alpha and beta radioactivity levels of the ... -
The radon concentrations of some waters in Bitlis (Turkey) and their dose estimates
(Sprınger, 2021)The activity concentration values of Rn-222 radio-isotope, which in an alpha active isotope, were measured in Bitlis and its district water samples in this study. The samples were analyzed with AlphaGuard PQ 2000 PRO active ... -
Antibacterial efficacy of ethyl pyruvate treatment against Escherichia coli O157:H7 and Salmonella Typhimurium on cherry tomatoes
(Akademıaı Kıado Zrt, 2021)Cherry tomatoes inoculated with Escherichia coli O157:H7 and Salmonella Typhimurium were treated with vaporised ethyl pyruvate (EP). The changes of microbial and organoleptic properties of the samples during storage were ... -
New species and new records of Pyraloid moths (Lepidoptera: Pyraloidea) from Turkey
