Post-fledging movements of Cinereous Vultures Aegypius monachus in Turkey revealed by GPS telemetry
(Nederlandse Ornithologische Unie, 2012)
Yamac E. & Bilgin C.C. 2012. Post-fledging movements of Cinereous Vultures Aegypius monachus in Turkey revealed by GPS telemetry. Ardea 100: 149-156. We studied the movements, home ranges and roost site preferences of three ...
New developments in alpha-SiAlON ceramics
(Elsevier Sci LTD, 1999)
Two different alpha-sialon compositions have been densified by either pressureless sintering or capsul-free sinter HIPing using either single cation namely strontium, lanthanum, cerium, neodymium or their equimolar mixtures ...
Displacement amplification of electroactive materials using the cymbal flextensional transducer
(Elsevier Science Sa, 2001)
High performance electroactive materials were studied as the driver element for the "cymbal" flextensional transducer. The compositions included were commercially available Navy Type I and PKT552 lead zirconate titanate ...
Exergetic Irreversibility and Sustainability Performances for Alternative Fuels in the Micro-Turbojet Engine
(Taylor & Francis Inc, 2018)
Design and modernization of the micro turbojet engine technology have an important problem related to fuel consumption in terms of economics and environmental. For this purpose, in this study, first, energy and exergy ...
Structural analysis of bio-oils from fixed-bed pyrolysis of Euphorbia rigida and sunflower pressed bagasse
(Taylor & Francis Inc, 2000)
Fixed-bed tars of Euphorbia rigida and sunflower pressed bagasse have been investigated for their structures. These mrs were fractionated into pentane-soluble and -insoluble compounds (asphaltenes). Pentane soluble were ...
The Apoptotic Effects of Escin in The H-Ras Transformed 5RP7 Cell Line
(Wiley, 2013)
Extracts of Aesculus hippocastanum L. (horse chestnut) seed have been used in the treatment of chronic venous insufficiency, edema and hemorrhoids. Most of the beneficial effects of horse chestnut are attributed to its ...
Mechanical properties of melt infiltrated boron carbide-aluminium composites
(Trans Tech Publications LTD, 2002)
Boron carbide (B4C)-aluminium (Al) composites were produced by melt infiltration of 2024-T3 series Al alloys into porous B4C compacts in the temperature range of 985 degrees -1370 degreesC under an inert atmosphere (Ar). ...
Chemical durability behaviour of bulk glasses in the SrO-Mn2O3Fe2O3-MgO-ZrO 2-SiO2 (SMFMZS) system
(2001)
It is known that the SrO-MgO-ZrO2-SiO2 (SMZS) system glasses with 40 weight % silica content seem to give a very high chemical endurance against highly alkaline solutions and can be recommended for the reinforcement of ...
On the limitations of the DFT plus U approach to energetics of actinides
(Elsevier Science BV, 2012)
Scalar-relativistic density functional theory calculations are performed on three phases of Np within the framework of LSDA+U approach. Material properties examined include lattice parameters, atomic volumes, bulk modulus, ...
Investigation of the phase composition and stability of the alpha-SiAlONs by the Rietveld method
(Elsevier Sci LTD, 2002)
Different compositions of Y- and Nd-alpha-SiAlONs were sintered at 1825 degreesC and analysed by the XRD method. The Rietveld technique was used for characterisation of the diffraction pattern and the x value of alpha-SiAlON, ...
