Relationships between Tennessee homemakers\u27 employment status, household size, club membership and extension contacts and their use of clothing construction practices

The major purpose of this study was to determine the relationship between the use of recommended clothing construction practices by homemakers and their employment status, household size, membership in an Extension Homemaker Club, selected personal and family characteristics and contacts with Extension. Data were obtained from the 1986 clothing construction survey through telephone or face to face interviews. Five hundred and forty eight homemakers in 29 Tennessee counties were surveyed. The “nth” number technique of random sampling was used to select respondents from counties EHC mailing lists, telephone directories and other available sources. The chi square (x2) test and the one-way analysis of variance F test was used to determine the relationships between selected independent and dependent variables. The .05 probability level was accepted as being statistically significant. Data were analyzed using the University of Tennessee Computing Center facilities. Major findings included the following: 1. As the number of homemakers using the recommended clothing construction practices increased, so did the number of office visits made, telephone calls made. Extension clothing publications received, mass media contacts, special interest meetings attended and Extension home-maker club meetings attended increase. 2. Extension homemaker club membership was significantly related to the homemakers use of 12 of the 21 recommended clothing construction practices. 3. Employment status was not significantly related to the homemakers use of 20 of the 21 recommended clothing construction practices. 4. Homemakers\u27 household size was not significantly related to the homemakers use of 19 of the 21 recommended clothing construction practices. 5. Homemakers\u27 age and place of residence was not significantly related to the homemakers use of recommended practices. 6. As the number of garments made increased, the number of recommended practices used by homemakers also increased. Homemakers who sewed for quality construction, good fit, enjoyment and to save money tended to use recommended practices at a higher rate. Implications were drawn and recommendations for further study were made

Superconductivity in heavy fermion compounds

We review the current state of experimental and theoretical investigations of heavy fermion superconductors. We discuss most of the Ce-based compounds like Ce122, Ce115, Ce218 and Ce131 classes and U-based superconductors like UBe_13 and UPd_2Al_3. In the former the emphasis is on the connection to quantum critical phenomena and non-Fermi liquid behaviour. Recent neutron scattering and hydrostatic pressure results on SDW/SC competition in the Ce122 system are included. For the U-compounds we discuss the significance of dual models with both localised and itinerant 5f electrons for mass enhancement and superconducting pair formation. Itinerant spin fluctuation theories for unconventional superconductivity are also reviewed.Comment: 74 pages, 29 figures.

Field-induced suppression of the heavy-fermion state in YbRh_2Si_2

We report DC magnetization measurements on YbRh_2Si_2 at temperatures down to 0.04K, magnetic fields B<11.5T and under hydrostatic pressure P<1.3GPa. At ambient pressure a kink at B*=9.9T indicates a new type of field-induced transition from an itinerant to a localized 4f-state. This transition is different from the metamagnetic transition observed in other heavy fermion compounds, as here ferromagnetic rather than antiferromagnetic correlations dominate below B*. Hydrostatic pressure experiments reveal a clear correspondence of B* to the characteristic spin fluctuation temperature determined from specific heat

Effect of hydrostatic pressure on the ambient pressure superconductor CePt_3Si

We studied the evolution of superconductivity (sc) and antiferromagnetism (afm) in the heavy fermion compound CePt_3Si with hydrostatic pressure. We present a pressure-temperature phase diagram established by electrical transport measurements. Pressure shifts the superconducting transition temperature, T_c, to lower temperatures. Antiferromagnetism is suppressed at a critical pressure P_c=0.5 GPa.Comment: 2 pages, 2 figures, proceedings SCES'0

Pressure-induced change of the pairing symmetry in superconducting CeCu2Si2

Low-temperature (T) heat-capacity measurements under hydrostatic pressure of up to p=2.1 GPa have been performed on single-crystalline CeCu2Si2. A broad superconducting (SC) region exists in the T-p phase diagram. In the low-pressure region antiferromagnetic spin fluctuations and in the high-pressure region valence fluctuations had previously been proposed to mediate Cooper pairing. We could identify these two distinct SC regions. We found different thermodynamic properties of the SC phase in both regions, supporting the proposal that different mechanisms might be implied in the formation of superconductivity.Comment: 4 pages, 5 figure

Bibliografía meteorológica y climatológica de la. República Argentina. Con un apéndice: Literatura sobre meteorología y climatología de las regiones antártica y sub-antártica americanas,

Con esta contribución la Bibliografía Científica Argentina avanza un paso más. Hay que reconocer, empreo, que falta todavía mucho para que ese trabajo llegue a su término, no obstante de existir ya bibliografía de algunas materias como ser: Ciencias Químicas, Botánica, Zoología, Geología, Mineralogía y Paleontología.Gran parte de los títulos de los trabajos con sus anotaciones respectivas de esta Bibliografía se debe a la valiosa obra de M. M. Welch "Bibliography on the climate of South America".Por existir una íntinma correlación entre el clima de la Argentina con el de la región antártica, se ofrece al final en un apéndice, una lista de trabajos que se refieren a la meteorología y climatología de las regiones antárticas y subantárticas americanas
