Transfer Of Photometric Quantities At Arbitrary Distribution Temperatures, İzmir Mamedbeyli̇, Zafer Ürey, A. Kamuran Türkoğlu
Transfer Of Photometric Quantities At Arbitrary Distribution Temperatures, İzmir Mamedbeyli̇, Zafer Ürey, A. Kamuran Türkoğlu
Turkish Journal of Physics
Characteristics of a photometric setup used for the measurement of photometric quantities at the National Institute of Metrology (UME) in Turkey are reported. A high accuracy method is developed to adjust the filaments of incandescent lamps with respect to the optical axis. The method also provides the basis for low uncertainty distance measurements between lamp filaments and photometers. Transfer of photometric quantities at arbitrary distribution temperatures is examined both theoretically and experimentally, and the results are compared to the calibration values of the Bureau International Des Poids Et Measures (BIPM), Paris, France.
Low-Temperature Phase Transition In Tl In Se_{2} Crystals, Oktay Zeynelabidin O Alekperov, Mazahir Amirjan Oglu Aljanov, Elmira M. Ali Gizi Keri̇mova
Low-Temperature Phase Transition In Tl In Se_{2} Crystals, Oktay Zeynelabidin O Alekperov, Mazahir Amirjan Oglu Aljanov, Elmira M. Ali Gizi Keri̇mova
Turkish Journal of Physics
Heat capacity, lattice parameter, spectral and temperature dependences of photoconductivity of chained crystal Tl In Se_{2} have been investigated in this work. For the first time, it has been found that the phase transtion takes plase at temperatures 135 and 184 K in this crystal. The changes of heat capacity, photoconductivity and lattice parameter of Tl In Se_{2} in the region of phase transition is supposed to be connected with the presence of an incommensurate phase in this crystal.
Coulomb Breakup Of Nucleus ^6 Li On Ion ^{208}Pb, B. F. Irgaziev, H. T. Ergashbaev
Coulomb Breakup Of Nucleus ^6 Li On Ion ^{208}Pb, B. F. Irgaziev, H. T. Ergashbaev
Turkish Journal of Physics
In the framework of the three-body approach the A(a,bc)A Coulomb breakup has been investigated. The three-body Coulomb dynamic is taken into account to derive the expression for the reaction matrix element. The mechanism of the breakup includes the direct process and the excitation of resonance state of the particle a. The calculation of the triple differential cross section of the ^{208}Pb(^6Li, \alpha d)^{208}Pb Coulomb dissociation have been performed in the energy region E_{\alpha d} < 1MeV. Calculations for the Coulomb dissociation ^{208}Pb(^6Li, \alpha d)^{208}Pb, including consideration of the triple cross section going through the first resonance of ^6Li have been performed. The results of the calculations are compared with experimental data.
Formation Of Hot Zone By The Application Of An Electric Field To Superconducting Bi_{1.6}Pb_{0.4}Sr_2ca_3cu_4o_X (2234) Rod, E. Yanmaz
Turkish Journal of Physics
The formation of hot zone by electric field on superconducting Bi-Pb-Sr-Ca-Cu-O (BSCCO) rods is described. Bulk samples with a nominal composition of Bi_{1.6}Pb_{0.4}Sr_2Ca_3Cu_4O_x (2234) were prepared as rods by a melt casting process. An electrical field was applied to the BSCCO rods and this current caused the resistance of the rod to fall and after a few minutes the initial voltage fell while the current was increased to 2.5A. Under certain conditions, a well-defined hot zone formed at the positive electrode, travelled along the rod and eventually disappeared on reaching the negative electrode. A small increase in the applied current …
Numerical, Image, And Signal Processing Algorithms Applied To Radar Rainfall Estimation, John Eugene Lane
Numerical, Image, And Signal Processing Algorithms Applied To Radar Rainfall Estimation, John Eugene Lane
Retrospective Theses and Dissertations
Since the advent of radar in the 1940s, it has been well known that water drops composing precipitation scatter microwaves in a predictable manner. This characteristic of early. radar has lead to the present day Weather Surveillance Radar (WSR-88D) or NEXRAD systems, operated by the National Weather Service (NWS). In parallel to the evolution of weather radar for measuring precipitation over large areas, remote networks of rain gauges have been deployed and managed by agencies such as the Florida Water Management Districts. Since the recent deployment of the NWS network of WSR-88D, as well as the recent launch of the …

Difference Method For A Singularly Perturbed Initial Value Problem, Gabi̇l Muhammadoğlu Amiraliyev
Difference Method For A Singularly Perturbed Initial Value Problem, Gabi̇l Muhammadoğlu Amiraliyev
Turkish Journal of Mathematics
In this paper we construct a completely exponentially fitted finite difference scheme for the initial value problem with small parameter by first and second derivatives. We prove the first order uniform convergence of the scheme in the sense of discrete maximum norm. Numerical results are presented.
Teaching For Educated Children, Jane Ericson
Teaching For Educated Children, Jane Ericson
Presidential Scholars Theses (1990 – 2006)
Considering the question, "What are the qualities of an educated child?" has been both a personal and professional journey for me. That question was what I sought to answer nearly a year ago and have been thinking about ever since. Through this paper I intend, not just to share any conclusions I have reached, but also describe the thinking process I went through to get there. Actually, the process may have been more significant than the end. I believe that it has been a worthwhile topic to investigate, helping me to grow as I complete my own formal education and …

An Analysis Of The Effects Of Study Skills Instruction On Reading Comprehension Of Middle School Resource Room Students, Govinda Dasi Harmon Gottes
Graduate Theses and Dissertations
Imagine that every day teachers, parents, and friends tell you to “try harder” and ask if you “get it?” You overhear teachers say that you do not “apply yourself”, and if you would only do your homework, you would learn everything much faster. Your parents bribe you with incentives, favorite activities, and even money if you would only bring home better grades. Your friends wonder if you are “dumb” and why you are not in any of their classes except for physical education and music. You have (or may have already for years) begun to think that there is something …

Environmental And Botanical Controls On Peatification - A Comparative Study Of Two New Zealand Restiad Bogs Using Py-Gc/Ms, Petrography And Fungal Analysis, Tomasz K. Kuder, Michael A. Kruge, J C. Shearer, S L. Miller
Environmental And Botanical Controls On Peatification - A Comparative Study Of Two New Zealand Restiad Bogs Using Py-Gc/Ms, Petrography And Fungal Analysis, Tomasz K. Kuder, Michael A. Kruge, J C. Shearer, S L. Miller
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
This study shows that chemical properties of two restiad species, Empodisma minus and Sporadanthus traversii, may contribute to their success as peat-formers in a climate of the North Island of New Zealand which is not conducive to raised mire development. Unlike Sphagnum, the equivalent northern hemisphere peat-former, restiads possess lignin in their tissues. In addition, the presence of non-lignin polyphenols (including tannins and phenolic acids) in restiads may be an important factor in peat formation due to the allelopathic decay retardation. Patterns of degradation of plant biopolymers have been examined and the pathway of degradation of monocotyledons (loss …

A Molecular Evaluation Of Contaminants And Natural Organic Matter In Surface Sediments From Western Lake Ontario, Michael A. Kruge, Prasanta K. Mukhopadhyay, C.F. Michael Lewis
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Pyrolysis-gas chromatography-mass spectrometry (Py-GC/MS) analysis of bottom sediment from Lake Ontario was shown to be effective in assessing organic contaminants, especially attractive as it is a rapid technique requiring little sample preparation. Pyrolyzates of samples richer in organic matter (OM) were relatively enriched in aliphatic hydrocarbons and pyrrolic nitrogen compounds, while leaner samples were more aromatic and pyridinic. Alkylbenzene and alkylphenol distributions in the pyrolyzates were most compatible with derivation from aquatic (algal, bacterial) OM. The organonitrogen compounds indicated the presence of degraded proteinaceous material from aquatic sources and/or sewage. Normal and polycyclic aromatic hydrocarbon distributions indicate, at least in …
