Opis:
Jerk is the time derivative of an acceleration vector and, hence, the third time derivative of the position vector. In this paper, we consider a particle moving in the three dimensional Euclidean space and resolve its jerk vector along the tangential direction, radial direction in the osculating plane and the other radial direction in the rectifying plane. Also, the case for planar motion in space is given as a corollary. Furthermore, motion of an electron under a constant magnetic field and motion of a particle along a logarithmic spiral curve are given as illustrative examples. The aforementioned decomposition is a new contribution to the field and it may be useful in some specific applications that may be considered in the future.

Opis:
In this study, microstructure and electrical properties of Ag-TiO₂ powders, which were prepared by a simple sol-gel method, are investigated. The sol was prepared from titanium iso-propoxide, Ti(OC₃H₇)₄ in iso-propanol (CH₃CHOHCH₃), used as solvent. AgNO₃ was used as the precursor for Ag. For the structural studies, the corresponding gels were allowed to dry naturally for about seven days, dried in an oven at 180°C for 30 min and then calcined at different temperatures (900, 1000 and 1100°C). The Ag-TiO₂ nanoparticles were characterized using differential thermal analysis/thermal gravimetry, scanning electron microscopy, energy-dispersive X-ray analysis and X-ray diffraction. The results X-ray diffraction indicate that pure Ag and TiO₂ powders are in rutile phase. However, calcination temperature had not significantly affected the crystalline structure of TiO₂. Scanning electron microscopy images of powders show an aggregation of small spherical particles of dispersed sizes. Annealing of the Ag-TiO₂ sample at high temperature produced more spherical particles, which aggregated to form bigger particles with porous structures. The electrical properties of the samples were measured using HMS-3000 Hall measurement system. The samples were found to be of n-type. The conductivity of TiO₂ samples have been explicitly increasing with calcination temperature and with Ag doping.

Opis:
In order to investigate the influence of the number of layers on the properties of ZrO₂ thin films, we prepared one pure ZrO₂ film sample with five layers and Ce, Eu, and Dy-doped ZrO₂ samples with single layer, by spin-coating sol gel-method. The crystal structures of thin films were determined using X-ray diffraction, morphology of the samples was analyzed by scanning electron microscopy, and the optical properties of the samples were determined by ultraviolet/visible absorbance measurements. The results of these measurements have shown that the concentration of the dopants and the thickness of thin film layers play a vital role in the physical, chemical, and optical properties of the pure and doped ZrO₂ thin films.

Opis:
Zirconium oxide (ZrO₂) is one of the widely studied oxide materials because of its excellent electrical, mechanical and optical properties. In this study, undoped and Dy-Eu-Ce co-doped ZrO₂ nanofibers were fabricated by electrospinning method and their crystal structure, surface morphology, optical properties, electrical and electronic properties, and chemical properties have been analyzed using X-ray diffraction, scanning electron microscope (SEM), UV/VIS spectrometer, four point probe technique (FPPT) energy dispersive X-ray (EDX) measurements, respectively.

Opis:
This study aimed to determine element concentration in coal samples and to assess Co, Cr, Se, Th and U leaching from coals exposed to a simulated coal cleaning process. Coal samples taken from a local area of Turkey were grounded and exposed to water for one month period. Then the cleaned samples were filtered and dried. The elemental concentrations in the samples before and after the cleaning procedure were determined by relative neutron activation analysis (NAA). Raw and water cleaned coal samples were irradiated in central irradiation tube of TRIGA MARK II Research Reactor at 250 kW for 6 h and measured for their activities by using high resolution gamma spectroscopy system. The results showed that leaching percentage for Se is up to 100% and for Co, Cr, Th and U up to 71%, 17%, 30%, 28% respectively.

Opis:
When foreign investors consider investment, the possibility of international commercial arbitration and the recognition and enforcement of foreign arbitral awards in the home country where the investment will take place can be a major factor to effect investment decision. This article aims to discuss the Turkish legal framework, domestic and international, of international commercial arbitration for foreign investors willing to invest in Turkey. In this study, subsequent to the definition of investment and investors in the Turkish law, recognition and enforcement of foreign awards, appeal and setting aside of awards and the possibility of interim measures will be discussed. Special emphasis will be given to the possibility of international commercial arbitration for Build Operate and Transfer Agreements where most of the investments occur.
