Adaptive beam-size control scheme for ground-to-satellite optical communications
(Society of Photo-Optical Instrumentation Engineers, Bellingham, WA, United States, 1999)
Atmospheric turbulence severely degrades the performance of ground-to-satellite optical links. Employment of adaptive optics to enhance ground-to-space optical communication systems has recently been considered and possible ...
Biostratigraphic and palaeoecologic study of the early Maastrichtian-Paleocene sediments in Kalecik region (Ankara-Turkey)
(King Fahd University of Petroleum and Minerals, 1999)
In this study, the Gansserina gansseri (early Maastrichtian), Morozovella
pseudobuUoides, Morozovella trinidadensis (Danian), Morozovella angulata (DanianThanetian), Planorotalites pseudomenardii, Morozovella velascoensis ...
Biostratigraphic and isotopic data on the Coreklik Member of the Hekimhan Formation (Campanian-Maastrichtian) of SE Turkey and their palaeoenvironmental significance
(Academic Press, 1999)
The Coreklik Member of the Hekimhan Formation crops out in the Hekimhan (Malatya) region of SE Turkey. It includes beds that are rich in planktic and benthic foraminifera, and in calcareous nannoplankton. Eighty-eight rock ...
Analytic formulas for calculating the quasistatic parameters of a multilayer cylindrical coplanar strip line
(John Wiley & Sons Inc, New York, 1999)
Fast, simple, and accurate analytic expressions are derived for calculating the quasistatic TEM parameters of a multilayer cylindrical coplanar strip line (MC CPS). The effects of the dielectric materials on the quasi-TEM ...
Hydrogeological study and discharge features of the niksar karst springs (Tokat-Turkey)
(King Fahd University of Petroleum and Minerals, 1997)
The exposed Paleozoic and Recent units in the study area have various hydrogeological characteristics such as pervious, semipervious, and impervious. Pervious limestones and associated impervious formations that were not ...
Hydrochemical and isotopic properties of the Mahmutlu and Bagdatoglu mineralized thermal springs, Kirşehir, Turkey
(Springer New York, 1999)
The present study identifies the hydrochemical and isotopic properties of the Mahmutlu and Bagdatoglu mineralized thermal springs in Kirşehir province, a geothermal field in central Anatolia, Turkey. Based on these properties, ...
Measurement of acid rain effect on soil microorganisms
(1997)
In this investigation, the sensitivity of decomposer microorganism to artificial acid rain (sulphite solution) was investigated. Decomposition of sycamore (Acer pseudoplatanus L.) leaf litter and activity of soil microorganisms ...
Measurement of SO2 deposition on decomposing leaf litter in a laboratory fumigation system
(1996)
Dry deposition of SO2 under laboratory conditions was investigated using environmentally-realistic concentrations of SO2 During a month of continuous fumigation of decomposing leaf litter, dry deposition of SO decreased ...
Hydrogeochemistry and isotopic study of the travertine deposition of the Tuzlusu (Aksaray) thermal-mineral springs
(1999)
Tuzlusu thermal-mineral springs emerge at the intersection of faults, parallel to the Tuzgolu fault zone and oblique to these faults in NW of Aksaray. The marbles of the Bozcaldag metamorphics, cropping out at Cal region ...
Optimum beam size for laser beam propagating through atmospheric turbulence
(1999)
A previous study concluded that the optimum beam diameter for a laser beam propagating through atmospheric turbulence is of the order of the coherence scale. It is shown that the optimum size is critically dependent on ...
