On the fusion problem for degenerate elliptic equations
1995
Let F be a relatively closed subset of a Euclidean domain Ω. We investigate when solutions u to certain elliptic equations on Ω/F are restrictions of solutions on all of Ω. Specifically, we show that if ∂F is not too large, and u has a suitable decay rate near F, then u can be so extended.
RAS proteins and control of the cell cycle inSaccharomyces cerevisiae
1995
Genes related to the mammalian H-, K-, and N-ras oncogenes were identified in S. cerevisiae by DNA hybridization techniques (for reviews, see Tamanoi, 1988; Gibbs and Marshall, 1989; Broach and Deschenes, 1990). According to the rules of yeast genetics (dominant genes are indicated by three capital letters followed by a number), the yeast genes were denominated RAS1 and RAS2 (collectively referred to as RAS). The corresponding RAS1 and RAS2 proteins were 309 and 322 amino acids long, respectively. The sequence similarity between the human and yeast proteins was very high, reaching 90% identity at the level of the N-terminal 80 amino acids. As a consequence, perfect sequence conservation was…
The SMILETRAP facility
1995
The SMILETRAP experimental set-up, a Penning trap mass spectrometer for highly charged ions, is described. Capture and observation of cyclotron frequencies of externally produced highly charged ions, rapid interchange of investigated and reference ions and measurements of the rotational kinetic energies are demonstrated. Mass measurements utilizing different charge states and species to verify the consistency of the measurements are presented. A relative uncertainty of about 10−9 is attained in comparisons between highly charged carbon, nitrogen, oxygen, neon and the singly charged hydrogen molecule.

BEM Formulation of the Trailing Edge Condition
1995
This paper deals with a BEM formulation of the trailing edge condition to determine the potential flow field around an airfoil. It is seen the trailing edge condition is not sufficient to give an unique solution. It is necessary to assign a further condition to eliminate the nonuniqueness of the solution. The approach allows to adopt a discretization into superior order elements. Some preliminary applications show the validity of the formulation.
Study of the subjet structure of quark and gluon jets
1995
Measurements of the subjet structure of quark and gluon jets in hadronic Z decays are presented. The analysis is based on one million hadronic events recorded by the ALEPH detector. Roughly symmetric three-jet events are selected with a coarse jet-resolution cut-off, y(1). Gluon jets are identified with a purity of 94.6% in those events where evidence of long-lived heavy-flavour hadrons in the other two jets is found. The jets are then analyzed using a smaller cut-off y(0) (< y(1)) so that subjets are resolved. The properties of the jets (subjet multiplicities [N-q], [N-g] and rates R(n)(g(q)) for n = 1,2,3,4) are determined and are found to be in good agreement with the expectations of per…
Projectile coulomb excitation with fast radioactive beams
1995
We report a search for gamma rays emanating from Coulomb excitation of fast (30-46 MeV/u) radioactive projectiles He-8, Be-11,Be-12,Be-14 interacting with a lead target. These are clearly identified by their Doppler shift. The 320 keV 1/2(-) --> 1/2(+)gamma transition from Be-11 was observed with a cross-section of 191 +/- 26 mb which is noticeably less than expected from the known lifetime and in the perturbation limit of pure Coulomb excitation. In the other nuclei rather stringent upper limits of 0.01 to 0.2 Weisskopf units, are placed on the hypothetical transition to 1(-) states.

Gangrena gaseosa: revisión de cuatro casos
1995
Desde el mes de enero de 1988 hasta diciembre de 1993, hemos atendido en el Servicio de Cirugía Ortopédica y Traumatología 6.853 pacientes, de ellos 263 presentaron infecciones post-quirúrgicas, post-traumáticas o expontáneas. Del total de infecciones cuatro se manifestaron como un cuadro clínico de gangrena gaseosa. El origen fue post-traumático en tres casos y por arma de fuego en uno, localizándose la enfermedad en todos los pacientes en las extremidades inferiores. Para establecer el diagnóstico además de las manifestaciones clínicas se ha valorado el resultado bacterológico y anatomo-patológico de las muestras analizadas. El tratamiento consistió en Cirugía precoz, antibioticoterapia y…

Leaf spray with Ti(IV) ascorbate improves the iron uptake and iron activity in Capsicum annuum L. plants
1995
Leaves of paprika pepper (Capsicum annuum L., cv Negral) plants sprayed with Ti(IV)-ascorbate showed an important increase of iron and titanium concentrations, as well as of the activity of peroxidase and catalase enzymatic systems. Leaf-Ti increase is similar for both greenhouse and field crop experiments, but increases in leaf Fe are more marked in plants growing under field conditions.

La projecció sintaxi-fonologia en els clítics del català i de l'espanyol
1995
This article covers Spanish and Catalan clitic pronouns according to the fundamental theoretical principles of Distributed Morphology. The author postulates that the syntax-phonology mapping of clitics consists of two submappings, the first from syntax to morphology and the second from morphology to phonology. In this second mapping, the clitics may suffer the effect of various morphological rules, specifically, the structural operations of Impoverishment, Adjunction, Fusion and Fission. The author proves that the complex and quirky behaviour of clitics and clitic clusters in Spanish and Barceloní can be easily explained by taking into account that these four operations act on the clitics'…

Selectivity in the direction of photoisomerization reactions in liquid-crystalline guest-host systems
1995
E ⇄ Z photoisomerization reactions of stilbenes la-c were studied in liquid-crystalline (LC) phases and in the corresponding isotropic melts. Whereas viscosity has a moderate influence on the photostationary states, a strong effect caused by the regular incorporation of the stilbene molecules in the LC phases was observed. The direction of the isomerization can be reversed, up to the case of a one-way isomerization Z E for the tailored guest-host system 1b/BS. Such an LC-matrix effect is of typical highly ordered (smectic) phases with free volumina which are strictly limited by hydrophobic interactions; it could not be detected in a much more mobile nematic phase. Textures based on the bire…

Forja de almas. La escuela rural en el franquismo a través de su cinematografia.
1995
El cine nos muestra una imagen de la escuela rural del franquismo muy alejada de los discurso triunfales de la Dictadura. Utilizando el cine como fuente historiográfica, el análisis de varias peliculas rodadas entre 1943 y 1977 nos permite comprobar la existencia de unas escuelas con materiales escasos, infraestructuras deficientes y una metodología pasiva, así como la predominancia de símbolos y contenidos del nacionalcatolicismo
La protección jurídica de la trashumancia aragonesa en el reino de Valencia: el Tribunal de la Bailia General
1995
A lo largo de la época foral moderna, los pastores de las Comunidades de Teruel y Albarracín descendieron todos los años a los pastos litorales valencianos, amparados por importantes franquicias que les liberaban del pago de impuestos, multas y confiscaciones por los daños ocasionados por el ganado. En este artículo analizamos tanto los privilegios de los trashumantes, como la aplicación de los mismos durante los siglos XVI y XVII a través de los procesos judiciales iniciados ante el tribunal de la Bailía General de Valencia.

Dynamic path length changes in all-fiber mirrors: Transmission modulation
1995
Abstract In this paper, we present a technique to modulate the transmission of an all-fiber mirror. This technique is based on the phase modulation of the light in the fiber loop, combined with the time delay between the clockwise and anticlockwise propagating beams. Using Jones calculus, a theoretical analysis has been carried out to describe the effects of static polarization changes and a dynamic phase modulation. An experimental all-fiber optical mirror has been constructed, and using a 1–MHz piezoelectric disc as the phase modulator, we demonstrate that it is possible to achieve either a 1–MHz or 2–MHz transmission modulation by adjusting the polarization state.
Keyhole limpet haemocyanin (KLH): Purification of intact KLH1 through selective dissociation of KLH2
1995
Abstract Keyhole limpet haemocyanin (KLH) from almost all newly captive animals contains a mixture of KLH1 and KLH2. We show that the dissociation of KLH2 can be produced during EM specimen preparation by the negative staining-carbon film (NS-CF) procedure and in solution by ammonium molybdate-PEG solutions at slightly acidic pHs. The KLH2 multidecamers split apart in the pH range 7.5-6.5 and in the pH range 6.5-6.0 the individual decamers break open and start to dissociate. At pH 5.9 the dissociation of KLH2 yields predominantly a mixture of single subunits and what appear to be subunit dimers. Over the pH range 7.0-5.7 the KLH1 didecamer remains stable. Separation of intact KLH1, in the f…
Landau damping in high-temperature superconductors
1995
We investigate the decay of a phonon into single-electron excitations in the cuprate superconductors. In a clean crystal the screening of the longitudinal phonon field cancels singularity of the Landau damping threshold and makes it experimentally unobservable. In a dirty metal the phase volume of the electrons involved in damping is small, which reduces the probability of the phonon decay. However, in this case the observation of dependence between the phonon linewidth and light penetration depth is more favorable than in the clean metal because the damping has no threshold.
