The 69 Millisecond Radio Pulsar Near The Supernova Remnant Rcw 103, V. M. Kaspi, Fronefield Crawford

Physics Faculty Scholarship

We report the detection of the radio pulsar counterpart to the 69 ms X-ray pulsar discovered near the supernova remnant RCW 103 (G332.4-0.4). Our detection confirms that the pulsations arise from a rotation-powered neutron star, which we name PSR J1617-5055. The observed barycentric period derivative confirms that the pulsar has a characteristic age of only 8 kyr, the sixth youngest of all known pulsars. The unusual apparent youth of the pulsar and its proximity to a young remnant require that an association be considered. Although the respective ages and distances are consistent within substantial uncertainties, the large inferred pulsar transverse …

The Effects Of Abdominal Strength Exercises And Testing On Posture In School Children, Greta L. Mcdonald, Kristin L. Nederveld

Masters Theses

The purpose of this study was to compare an abdominal strength testing method used in school systems to tests used in the physical therapy profession. Results were associated with lumbar lordosis. The study included 58 female and 5 male subjects between 10-11 years old from two school districts. Kendall’s Upper Abdominal Test, Kendall’s Lower Abdominal Test and The Presidential Physical Fimess Test were performed in random order. Lumbar lordosis was measured before and afrer abdominal testing by recording the curvature of the low back using a flexible ruler. A Chi-square analysis was used to demonstrate the association of abdominal strength …

Measured And Simulated Performance Of Reflective Roofing Systems In Residential Buildings, Florida Solar Energy Center, Danny Parker

FSEC Energy Research Center®

A series of experiments in Florida residences have measured the impact on space cooling of increasing roof solar reflectance. In tests on 11 homes with the roof color changed mid summer, the average cooling energy use was reduced by 19%. Measurements and infrared thermography showed that a significant part of the savings were due to interactions when the duct system is located in the attic space. An improved residential attic and duct simulation model, taking these experimental results into account, has been implemented in the DOE-2.1E building energy simulation program. The model was then used to estimate the impact of …

Measurement Of The Axial-Vector Τ Spectral Functions And Determination Of Αs (M2Τ) From Hadronic Τ Decays, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

An analysis based on 124 000 selected ττ pairs recorded by the ALEPH detector at LEP provides the vector (V)(V) and axial-vector (A)(A) spectral functions of hadronic ττ decays together with their total widths. This allows the evaluation of finite energy chiral sum rules that are weighted integrals over the (V−A)(V−A) spectral functions. In addition, a precise measurement of αsαs along with a determination of nonperturbative contributions at the ττ mass scale is performed. The experimentally and theoretically most robust determination of αs(M2τ)αs(Mτ2) is obtained from the (V+A)(V+A) fit that yields αs(M2τ)=0.334±0.022αs(Mτ2)=0.334±0.022 giving αs(M2Z)=0.1202±0.0027αs(MZ2)=0.1202±0.0027 after the extrapolation to the mass …

Search For Evidence Of Compositeness At Lep I, R. Barate, M. Thulasidas

Research Collection School Of Computing and Information Systems

Extensive searches for evidence of compositeness of quarks and leptons have been made in the complete set of ALEPH data from LEP running at the Z peak. These include searches for radiative and weak decays of excited fermions, produced either in pairs or singly, and a scalar partner of the Z. Coupling and branching ratio limits deduced from these searches are presented.

The Effectiveness Of A Strength Training Program On Extremity Strength, Flexibility, And Balance Of Elderly Women, Patricia L. Murphy

Master's Projects

This quasi-experimental study, partially replicating that of Nelson and Wernick (1997), compares balance, flexibility, and extremity strength before and after an 8-week weight-bearing exercise class. Six women, aged 69 to 85, used 1-5 pound wrist weights and ankle weights up to 1 o pounds. Pre-and post-exercise measurements of biceps curls, seated leg lifts with weights, one leg stand, and seated stretches were gathered. Results showed improvement in every category, with the greatest improvement (41.6%) in balance and the least (8.3%) in trunk flexibility. Nursing is uniquely positioned to assist this population by promoting, developing, and implementing such exercise programs.

Azobenzene Side-Chain Liquid Crystalline Polyesters With Outstanding Optical Storage Properties, S. Hvilsted, M. Pedersen, N.C.R. Holme, P.S. Ramanujan

Turkish Journal of Chemistry

A flexible azobenzene side-chain liquid crystalline (SCLC) polyester architecture employed for reversible optical storage is described. The modular design allows four structural parameters to be individually modified. These parameters: {\em i}- the methylene side-chain spacer length, {\em ii}- the substituent on azobenzene, {\em iii}- the methylene main-chain segment length, and {\em iv}- the polyester molecular mass, all influence the optical storage properties. A general synthetic route to novel mesogenic azobenzene diols comprising parameters {\em i} and {\em ii} is outlined. Polyesters with molecular masses (parameter {\em iv}) up to 100,000 are routinely obtained by melt transesterification of the novel diols …

Xps Investigations On Conducting Polymers, Ş. Süzer, Ö. Bi̇rer, U.A. Sevi̇l, O. Güven

Turkish Journal of Chemistry

X-ray photoelectron spectroscopy, XPS, was used for the characterization of electrically conducting polymeric materials. In the spectrum of polypyrrole, PPy, the Nls region exhibits two peaks, at 402.0 and 399.8 eV, corresponding to -N$^+$- and -N- moieties, respectively. The intensity of the N$^+$ peak decreases as the material loses its conductivity, hence the ratio of the experimentally derived N$^+$/C atomic ratio correlates exponentially with the measured conductivity. A similar observation also exists between the F$^-$/C atomic ratio both in polypyrrole and polythiophene. In the XPS spectrum of the composite material prepared using polyaniline, PAN and polyvinylchloride, PVC, two different kinds …

Dimerization Of Pyrrole, Mine Yurtsever, Ersin Yurtsever

Turkish Journal of Chemistry

Accurate ab-inito quantum mechanical calculations of pyrrole dimers are reported. The thermodynamical stabilities of dimers with $\alpha - \alpha, \alpha - \beta$, and $\beta - \beta$ type linkages are compared in order to predict the possibilities of branching in polypyrroles. Calculations employing large basis sets and including electron correlation effects predict the $\alpha - \alpha$ dimers as the most stable form. However, an $\alpha - \beta$ type bonding requires only 1.5-2.0 kcal/mol, and the energy necessary to introduce a $\beta - \beta$ type bond is 3.6-4.0 kcal/mol. These values show that a high degree of branching is possible even at …

Reaction Of 3,4-Diformyl-2,5-Dimethylpyrrole With 1,2(Substituted)Diphenyl-1,2-Diaminoethanes, Cemil Öğreti̇r, Fatma Severcan

Turkish Journal of Chemistry

3,4-Diformyl-2,5-dimethylpyrrole (1) reacts with 1,2-diphenyl-1,2-diamine derivatives to form the potentially tautomeric 2:2 macrocyclic adduct (1)=(1). ^1H and ^{13}C n.m.r. spectral data along with acidity measurements indicate that the 2-azafulvene structure (7) is predominant for all adducts.

Theoretical Studies On The Configurations Of Benzhomobarrelene Derivatives, Rıza Abbasoğlu, Abdullah Menzek, Metin Balci

Turkish Journal of Chemistry

Reaction of 7-carbomethoxy-cycloheptatriene with benzyne resulted in the formation of only one benzhomobarrelene isomer, {\bf 5A}. Theoretically, four addition products, {\bf 5A-D}, can be formed from this reaction. Certain molecular mechanic calculations (MM2 force field) have been undertaken on these isomers. It has been shown that the isomers {\bf 5A} and {\bf 5C} have the lowest energies. The non-existence of {\bf 5C} has been discussed in terms of a benzyne approach to a norcaradiene structure. Furthermore, MM2 calculations on two different conformers of {\bf 5A} have revealed that the bisected conformer {\bf 5AE} has the highest strain energy. However, AM1 …
