Inelastic neutron scattering measurements on several Tl filled skutterudites (Tl0.5Co3.5Fe0.5Sb12, Tl0.8Co3FeSb12, and Tl0.8Co4Sb11Sn) all show a sharp peak in the vibrational density of states at 57 +/- 2 K, which is absent in the unfilled skutterudite CoSb3. Heat capacity measurements on Tl0.8Co4Sb11Sn as compared to CoSb3 are consistent with the presence of a localized vibrational mode associated with the "rattling" thallium atoms in this filled skutterudite compound. Both results are well described by a localized Einstein mode model with an Einstein temperature Theta(E) of 53 +/- 1 K. These data provide perhaps the clearest example of local mode behavior in a concentrated metallic system. [less ▲]

The Einstein model of a solid usually lacks a clear illustration in introductory solid-state physics courses because most solids are much better described by the Debye model. Filled antimony skutterudites, materials that have recently attracted much attention because of their potential for thermoelectric applications, provide a canonical illustration of the Einstein model. The filling atoms are loosely bound in the atomic cage formed by their neighbors, and hence their description as independent harmonic oscillators is adequate. Simple models for the heat capacity and thermal conductivity of a solid are introduced, with emphasis on the density of vibrational states. These models are used in conjunction with experimental results obtained from heat capacity and inelastic neutron scattering measurements to demonstrate the applicability of the concept of the Einstein oscillator to the filling guests in antimony skutterudites. The importance of these Einstein oscillators for impeding thermal transport is discussed and some simple problems involving the heat capacity, thermal conductivity, and inelastic neutron scattering are proposed.

We present the first observations of the initiation of a coronal mass ejection (CME) seen on the disk of the Sun. Observations with the EIT experiment on SOHO show that the CME began in a small volume and was initially associated with slow motions of prominence material and a small brightening at one end of the prominence. Shortly afterward, the prominence was accelerated to about 100 km s[SUP]-1[/SUP] and was preceded by a bright loop-like structure, which surrounded an emission void, that traveled out into the corona at a velocity of 200 400 km s[SUP]-1[/SUP]. These three components, the prominence, the dark void, and the bright loops are typical of CMEs when seen at distance in the corona and here are shown to be present at the earliest stages of the CME. The event was later observed to traverse the LASCO coronagraphs fields of view from 1.1 to 30 Ro. Of particular interest is the fact that this large-scale event, spanning as much as 70 deg in latitude, originated in a volume with dimensions of roughly 35" (2.5 x 10[SUP]4[/SUP] km). Further, a disturbance that propagated across the disk and a chain of activity near the limb may also be associated with this event as well as a considerable degree of activity near the west limb.

The Extreme Ultraviolet Imaging Telescope (EIT) on board the SOHO spacecraft has been operational since 2 January 1996. EIT observes the Sun over a 45 x 45 arc min field of view in four emission line groups: Feix, x, Fexii, Fexv, and Heii. A post-launch determination of the instrument flatfield, the instrument scattering function, and the instrument aging were necessary for the reduction and analysis of the data. The observed structures and their evolution in each of the four EUV bandpasses are characteristic of the peak emission temperature of the line(s) chosen for that bandpass. Reports on the initial results of a variety of analysis projects demonstrate the range of investigations now underway: EIT provides new observations of the corona in the temperature range of 1 to 2 MK. Temperature studies of the large-scale coronal features extend previous coronagraph work with low-noise temperature maps. Temperatures of radial, extended, plume-like structures in both the polar coronal hole and in a low latitude decaying active region were found to be cooler than the surrounding material. Active region loops were investigated in detail and found to be isothermal for the low loops but hottest at the loop tops for the large loops. [less ▲]

The Extreme-ultraviolet Imaging Telescope (EIT) will provide wide-field images of the corona and transition region on the solar disc and up to 1.5 Ro above the solar limb. Its normal incidence multilayer-coated optics will select spectral emission lines from Fe IX (171 Å), Fe XII (195 Å), Fe XV (284 Å), and He II (304 Å) to provide sensitive temperature diagnostics in the range from 6 × 10[SUP]4[/SUP] K to 3 × 10[SUP]6[/SUP] K. The telescope has a 45 x 45 arcmin field of view and 2.6 arcsec pixels which will provide approximately 5-arcsec spatial resolution. The EIT will probe the coronal plasma on a global scale, as well as the underlying cooler and turbulent atmosphere, providing the basis for comparative analyses with observations from both the ground and other SOHO instruments. This paper presents details of the EIT instrumentation, its performance and operating modes. [less ▲]

Il existe actuellement une tendance à réserver le diagnostic de trouble de l‘éjaculation précoce (EP) aux seuls cas caractérisés par des durées de pénétration inférieures ou égales à une minute environ. L’idée sous-jacente est que ces situations relèveraient d’une étiologie essentiellement bio-constitutionnelle et qu’un traitement pharmacologique au long cours constituerait l’unique option thérapeutique valable. À l’examen de la littérature cependant, les évidences scientifiques invoquées en soutien de cette proposition apparaissent assez faibles. Bon nombre de personnes souffrant d’éjaculer trop rapidement présentent en effet des durées de pénétration supérieures à une minute, et il semble que les formes sévères d’EP puissent aussi répondre favorablement à des traitements psycho-sexologiques. En outre, s’il s’avère certain que des variables biologiques influencent la latence éjaculatoire, rien ne permet cependant de prétendre qu’elles jouent, dans les formes sévères d’EP, un rôle exclusif de facteurs étiologiques psychosociaux. Il apparaît ainsi « prématuré » de fonder le diagnostic d’EP sur une durée de pénétration d’une minute maximum, ce critère détermine plutôt un gradient de sévérité du trouble. Considérant que, en matière de durée de pénétration, les critères d’aspiration se situent souvent au delà des normes biologiques, il semble délicat de soutenir que seules les formes d’EP les plus sévères auraient une origine bio-constitutionnelle. Dans tous les cas au demeurant, la constitution s’avère relativement plastique, sensible aux apprentissages à visée adaptative. Ceux-ci sont sans doute plus difficiles à réaliser par les porteurs d’une forme sévère du trouble, mais pas impossibles. La question de l’indication d’un traitement pharmacologique ou psycho-sexologique gagnerait à se dégager d’un simple critère de latence éjaculatoire. [less ▲]
