Associations Of X-Ray Binaries With Open Clusters And Supernova Remnants, Eni̇s Tuncer, H. Guseinov, Ü. Kiziloğlu, A. O. Allakhverdiev

Turkish Journal of Physics

Searching for X-ray binaries projected on open clusters (OCs) and supernova remnants (SNRs), associations of X-ray binaries with OCs and SNRs in the Galaxy are discussed. Three of the high mass X-ray binaries (HMXBs) and four of the low mass X-ray binaries (LMXBs) are projected on open clusters. Five of HMXBs and six of LMXBs are projected on SNRs. The number of the HMXB projections are less than the LMXBs, which is not expected and is surprising since the objects in this study, except the LMXBs, are all young objects. Such associations help us improve distance and age estimates of …

Ferromagnetic Transitions In Ni-Mn Alloys, F. Boakye, R. K. Nkum

Turkish Journal of Physics

Ferromagnetic transitions in nickel and nickel-manganese alloys have been studied using resistivity-temperature measurements from 800 to 77 K. The results establish the transition temperature of nickel as 610 K and the transition temperature is shifted to lower values as the concentration of Mn in the alloy is increased. Analysis of the resistivity results near the ordering temperature \( (T

Interaction Between Cesium Chloride Molecules And Metal Atoms Under Coadsorption On A Single Graphite Layer On Iridium, N. M. Nasrullaev

Turkish Journal of Physics

Using the method of continuos flow to investigate the kinetics of reaction between atoms and molecules, the efficiency of substitution reactions (K, Na, Li)+ CsCl is shown to decrease. The efficiency is found to strongly depend on temperature tending to saturation with decreasing temperature. This fact is in accordance with Bonzel's concept.

Thermal Stability Of Fe_{85.5}B_{14.5} Metallic Glass, Asghari Maqsood, Ashfaq Ahmad

Turkish Journal of Physics

The thermal stability and crystallization behaviour of metallic glass Fe\( _{85.5} \)B\( _{14.5} \) were investigated by Dynamic Temperature Resistivity Measurement (DTRM) technique from room temperature to 1050K in forward and reverse mode at a heating rate of 40 K/hr. The slope of Resistivity-Temperature-Curve (RTC) changes sign and magnitude at the temperature where the transition takes place. Differential Thermal Analysis (DTA) was carried out at the heating rates of 10, 20, 30 \& 40 K/min. A comparison of the results of DTRM and DTA measurements shows that crystallization in this alloy is two-stage process. Activation energy for two crystallization steps …

Radioluminescent Properties Of Cds(Ag) Crystals, Ruhi̇ Kaplan, F. Esen Özsan

Turkish Journal of Physics

The radioluminescent proporties of silver-doped cadmium sulphide, CdS(Ag), crystals excited by 5.5 MeV $ \alpha $-particles from an $ ^{241}$Am radioactive source have been investigated. The emission spectra, decay profiles and thermal quenching curves were obtained accurately at temperatures between 80 K and 300 K. Two main radioluminescent emission bands centered at about 5760 \AA\ and 5940 \AA\ were observed. Their decay curves were found to be fast and nonexponential. From the thermal quenching of radioluminescence, the activation energies of centers responsible for these emissions were determined. The results are interpreted as the radioluminescence is possibly due to donor-acceptor pair …

K-Vacancy Production In The Collision Of Highly Charged Relativistic Ions With Heavy Atoms, P. K. Khabibullaev, V. I. Matveev, D. U. Matrasulov

Turkish Journal of Physics

A general expression for the cross section of the inelastic collision of relativistic highly charged ion with heavy (relativistic) atoms is obtained using the generalized eikonal approximation. In the ultrarelativistic limit, the obtained formula coincides with a known exact one. As an application of the obtained result, probability and cross section of the K-vacany production in the $U^{92+} - U^{91+}$ collision are calculated.

Barrier Heights Of Antimony / And Bismuth / P -Silcon (100) Junctions, A. A. Oberafo, A. Z. Ziriki

Turkish Journal of Physics

Junctions were fabricated in vacuum of about $10^{-5}$ Torr by thermal evaporation of Sb or Bi onto chemically etched $p$-type silicon (100) substrates. The electrical properties were studied by current voltage (I-V) measurements. Some of the Sb and Bi junctions were heated-treated for $\frac{1}{2}$ hr at 200 and 150^oC, respectively. The barrier height (BH) was equal to 0.64 eV for both as-deposited and heat-treated Sb junctions, while it was 0.56 and 0.74 eV for as-deposited and heat-treated Bi Junctions, respectively. These observatimons indicate that for Sb junctions, annealing at a temperature of 200^oC resulted only in partial elimination of any …

Kinetics Of The Photolysis Of Benzenetricarbonylchromium(0) In Chloroform, Leslianna Federici, Patrick E. Hoggard

Chemistry and Biochemistry

In contrast to the photolysis of Cr(CO)₃(C₆H₆) in nonhalogenated solvents, in which the products are CrL(CO)₂(C₆H₆) in the presence of a donor L, or Cr(CO)₆ and C₆H₆ if no donor is present, the photo-reaction in chloroform yields CrCl₃. No significant portion of the reaction occurs through absorption of 254nm light by CHCl₃• The quantum yield is 1.4, consistent with a mechanism in which several radicals are formed upon chlorination of the chromium, which then cause further decomposition of the reactant. …

Evaluation Of Effect Of Excipients, Temperature And Humidity On The Stability Of Levothyroxine Sodium, Niraj S. Amin

Open Access Master's Theses

Levothyroxine Sodium is one of the most critical drugs for a significant segment of the population. The development of HPLC method of analysis for levothyroxine sodium revealed that there were significant stability problems associated with this drug. On August 14, 1997, FDA announced that there was evidence which shows significant stability and potency problems associated with orally administered levothyroxine sodium products. This lack of stability and potency has a potential to cause serious health consequence to the public. The literature, on determining the stable formulation of levothyroxine sodium is very little. Much of the published work on levothyroxine sodium describes …

Predicting Milk And Soft Drink Consumption Among Female Adolescents Using The Theory Of Planned Behavior, Nada Osman Kassem

Loma Linda University Electronic Theses, Dissertations & Projects

A total of 756 female adolescents, aged 13 to 18 years, from five public high schools in Antelope Valley Union High School District located in North Los Angeles County participated in this study between February 1999 and March 1999. The ethnic composition was 53.3% White/Anglo Americans, 19.3% Hispanics or Latinos and 10.2% Black/African Americans. The constructs of the Theory of Planned Behavior (attitude, subjective norm, and perceived behavioral control and their underlying beliefs) were assessed to determine the predictors of low-fat milk and regular soda consumption. A cross-sectional design with group-administered questionnaires was utilized.

Most participants (89.6%, n = 636) …

Risk Factors Associated With Infant Mortality Among Very Low Birthweight Infants Of Teenage Mothers In San Bernardino County, C. Letitia Henry

Loma Linda University Electronic Theses, Dissertations & Projects

Background. Typically, infant mortality decreases as maternal age increases in teenagers. In contrast to these national data, San Bernardino County (SBC) experienced a different phenomenon in 1989-1994 among very low birthweight (VLBW) infants. The infant mortality rate (IMR) of VLBW infants born to mothers under 17 years old (283 per 1000 live births) was significantly lower than the IMR of VLBW infants born to mothers between the ages of 17-19 years old (430 per 1000 live births) (p = .02).

Purpose. The purpose of the study was to explain the discrepancy between IMRs of VLBW infants of younger teenage mothers …

Aspects Of Growth For The Northern Quahog, Mercenaria Mercenaria, Craig Lawrence Appleyard

Open Access Master's Theses

The growth of the northern quahog, Mercenaria mercenaria, has been mathematically modeled over both the nursery stage and the complete life so as to develop expectations of growth as a function of environmental suitability. Then, the growth of northern quahogs in an experimental nursery upweller was evaluated as a function of system operating parameters (flow rate and stocking density) and other environmental parameters to determine the limiting factors in this critical phase of shellfish aquaculture.

The von Bertalanffy growth equation was used to predict increases in shell length (millimeters), weight (grams), and the relative growth rate (% increase per …

Educational Research Abstracts, G. Bass Jr.

Journal of Mathematics and Science: Collaborative Explorations

Editors' Note: As noted in previous issues of the Journal of Mathematics and Science: Collaborative Explorations, the purpose of this Educational Research Abstract section is to present current published research on issues relevant to math and science teaching at both the K-12 and college levels. Because educational research articles are published in so many different academic journals, it is a rare public school teacher or college professor who reads all the recent published reports on a particular instructional technique or curricular advancement. Indeed, the uniqueness of various pedagogical strategies has been tacitly acknowledged by the creation of individual journals dedicated …

A Challenge To All: Raising The Participation And Success Of Women And Minorities In Mathematics, Science, And Technlogy, Mark R. Warner, Loren D. Pitt

Journal of Mathematics and Science: Collaborative Explorations

This issue of our journal is the product of a Virginia Mathematics and Science Coalition (VMSC) conference titled, "Programs That Work" and held in March, 2000 on the issues of raising both the levels of success and the levels of participation of women and minorities in mathematics, science, and technology. Traditionally, these two groups have had low rates of participation in these subjects, and we believe this situation can and must be changed. The conference was to Coalition's first direct assault on the problem.
