Experimental determination of pressure losses and critical velocities in transporting sand by water
(1996)There is not a reliable theoretical method of calculation regarding the solid material transport in pipes. Therefore, the systems which transport solid material by fluid have been designed by using experimental results. ... -
Secondary effects of SO2 pollution on leachate chemistry and decay of scots pine and mixed angiospermous leaf litters
(Elsevier Ltd, 1996)The secondary effects of SO2 fumigation on CO4 evolution from leaf litter of Scots pine (Pinus sylvestris L.) and mixed broad-leaved species [Quercus petraca mattuschka (Liebl.), Fraxinus excelsior L., Betula pubescens ... -
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 ... -
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 ... -
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 ... -
Renewable energy potential as an alternative to fossil fuels in Turkey
(Elsevier Ltd, 1999)Clean, domestic and renewable energy is commonly accepted as the key for future life, not only for Turkey but also for the world. All nations, regardless of their degree of development, are trying to develop and apply ... -
Analytic formulas for calculating the quasistatic parameters of a multilayer cylindrical coplanar strip line
(John Wiley and Sons Limited, 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 ... -
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 ... -
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, ... -
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 ... -
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 ... -
