A phase diagram near the NAC point in liquid crystals
(Elsevier Science SA, 2002-07-28)In this study using a mean field model we obtain the phase line equations for the NA. NC and AC transitions near the NAC point in a mixture of liquid crystals. We then fit these phase line equations to the experimental ... -
Yeşilırmak Taraçalarında (Orta Kuzey Anadolu) Geç Pleyistosen İklim Değişiklikleri ve Düşey Yönlü Deformasyona Akarsu Cevabının Araştırılması
(TMMOB Jeoloji Mühendisleri Odası, 2017)River terraces are remnants of former river floodplains that are fossilized above present-day river channels, often in staircase systems. The formation of terrace staircases is attributed to both tectonic, climate and ... -
Tectonic and climatic controls on Quaternary fluvial processes and river terrace formation in a Mediterranean setting, the Goksu River, southern Turkey
(Cambridge Univ Press, 2019-03)Climate and tectonics effect the fluvial evolution of the Mediterranean Mut basin. The basin contains a river terrace staircase of 16 levels (T16-T1) ranging from 365 to 10m above the current Goksu River in its middle and ... -
Quaternary uplift of the northern margin of the Central Anatolian Plateau: New OSL dates of fluvial and delta-terrace deposits of the Kizilirmak River, Black Sea coast, Turkey
(Pergamon-Elsevier Science Ltd, 2018-12-01)We analysed the interplay between coastal uplift, sea level change in the Black Sea, and incision of the Kizilirmak River in northern Turkey. These processes have created multiple co-genetic fluvial and marine terrace ... -
Future projections of temperature and precipitation climatology for CORDEX-MENA domain using RegCM4.4
(Elsevier Science Inc, 2018-07-01)In this study, we investigate changes in seasonal temperature and precipitation climatology of CORDEX Middle East and North Africa (MENA) region for three periods of 2010-2040, 2040-2070 and 2070-2100 with respect to the ... -
Particle Size and Shell Thickness Dependence of the Light Intensity Enhancement in the Cap Layers of Ag, Au, Al and SiO2@TiO2 Core-Shell Nanostructures
(Wiley-V C H Verlag GMBH, 2018-03-22)We present a systematic study of the light intensity enhancement in the shell layers of half burrried Ag, Au, Al and SiO2 spherical nanoparticles capped with TiO2. We calculated the light intensity profiles near these ... -
Eolianite and coquinite as evidence of MIS 6 and 5, NW Black Sea coast, Turkey
(Elsevier B.V., 2017-04)This paper discusses the implications of a lowstand carbonate eolianite and overlying transgressive sequence of coquinite at Şile on the Turkish Black Sea coast based on composition, depositional characteristics and optical ... -
A realistic quantum capacitance model for quantum Hall edge state based Fabry-Pérot interferometers
(Institute of Physics Publishing, 2017-01-25)In this work, the classical and the quantum capacitances are calculated for a Fabry-Pérot interferometer operating in the integer quantized Hall regime. We first consider a rotationally symmetric electrostatic confinement ... -
Projected changes in temperature and precipitation climatology of Central Asia CORDEX Region 8 by using RegCM4.3.5
(Elsevier Ltd, 2017-01-01)This work investigated projected future changes in seasonal mean air temperature (°C) and precipitation (mm/day) climatology for the three periods of 2011–2040, 2041–2070, and 2071–2100, with respect to the control period ... -
Impact of climate change on natural snow reliability, snowmaking capacities, and wind conditions of ski Resorts in Northeast Turkey: a dynamical downscaling approach
(Mdpi Ag, 2016-04)Many ski resorts worldwide are going through deteriorating snow cover conditions due to anthropogenic warming trends. As the natural and the artificially supported, i.e., technical, snow reliability of ski resorts diminish, ... -
Records of repeated drought stages during the Holocene, Lake Iznik (Turkey) with reference to beachrock
(Pergamon-Elsevier Science Ltd., 2016-07-15)The cement fabrics, subsurface nature and optically stimulated luminescence age of beachrocks along the shores of Lake Iznik in NW Turkey were studied within the context of Holocene lake level changes. With a maximum ... -
Did Amphistegina lobifera Larsen reach the Mediterranean via the Suez Canal?
(Elsevier Ltd., 2016-05-16)It has been accepted by many researchers that Amphistegina lobifera Larsen migrated to the Mediterranean Sea via Suez Canal like many other Indo-Pacific originated foraminifers and organisms. This idea was also supported ... -
Dating fossil root cast (Black Sea coast, Turkey) using thermoluminescence: Implications for windblown drift of shelf carbonates during MIS 2
(Elsevier Ltd., 2016-05-16)Rhizoliths are mostly sub-aerially exposed root prints which appear through removal of the rock units that cap them. A horizontal-lying residual of a rhizolith, consisting purely of soft inner core material of white color ... -
Cement fabrics and optical luminescence ages of beachrock, North Cyprus: Implications for Holocene sea-level changes
(Elsevier Ltd., 2016-05-16)CaCO3-cemented beachrocks are widely found along the northern coast of Cyprus. In this study, we aim to discuss the cementation history of beachrocks at ten particular sites within the context of Holocene sea-level changes. ... -
Spatial slip behavior of large strike-slip fault belts: Implications for the Holocene slip rates of the eastern termination of the North Anatolian Fault, Turkey
(Blackwell Publishing Ltd, 2015-12)We present new data on Holocene slip rates for the eastern end of the North Anatolian Fault (NAF) by using the optically stimulated luminescence ages of the offset terrace deposits at two sites, where a total of four ... -
Projections of climate change in the Mediterranean Basin by using downscaled global climate model outputs
(Wiley-Blackwell, 2015-11-30)The Mediterranean Basin is one of the regions that shall be affected most by the impacts of the future climate changes on hydrology and water resources. In this study, projected future changes in mean air temperature and ... -
An Optical Setup for Deterministic Creation of Four Partite W state
(Polish Academy of Sciences, 2015-04)In order to create polarization based entanglement networks of W-4 state, we propose an optical setup, which uses only four horizontally polarized photons as resource which implies no entanglement requirement as a resource. ... -
Spectral renormalization group for the Gaussian model and ψ4 theory on nonspatial networks
(Amer Physical Soc, 2015-08-06)We implement the spectral renormalization group on different deterministic nonspatial networks without translational invariance. We calculate the thermodynamic critical exponents for the Gaussian model on the Cayley tree ... -
Temperature lags of luminescence measurements in a commercial luminescence reader
(Elsevier Science Inc, 2015-09-15)The temperature recorded in thermoluminescence and optically stimulated luminescence equipments is not the temperature of the sample but that of the heating element on which the thermocouple is attached. Depending upon the ... -
