La lexicografia catalana a l'Alguer
1994
The re are a few alguerès works made with lexicographic methods or pretensions, apart from some contributions more or less interesting or useful for the knowledge of the local language, intended principally for dialectologists: only two titles produce explicitly the label of «Vocabulary» or «Dictionary» and use the typical structure of this kind of works. We can add to these references an unpublished work by G. Palomba.

Extracellular Structural and Secretory Proteins
1994
The extracellular matrices of animal tissues consist of networks of collagens and elastins, the meshes of which are filled with structural glycoproteins and glycosaminoglycans. The cells themselves are in direct contact with the basement membranes, which are specific regions of the extracellular matrix with a thickness of 20200 nm. The very varied compositions of the different extracellular matrices determine their mechanical characters and, in particular, their interactions with the cells [73]. The binding of cells to various matrix components is mediated by specific receptors on the cell surface and these recognize certain peptide sequences in the matrix proteins [141]. Several particular…
Paternity testing of endangered species of birds by DNA fingerprinting and random amplified polymorphic DNA fingerprinting
1994
Since 1985 DNA fingerprinting is the method of choice to solve forensic problems such as paternity testing (Jeffreys et al., 1986) or identification of immigration cases (Jeffreys et al., 1985 a, b). Its applicability became evident not only in man but also in many biological problems. Jeffreys’probes 33.15 and 33.6 or Epplen’s oligonucleotide probes were used in DNA fingerprinting of dogs and cats (Jeffreys & Morton, 1987), non-human primates (Weiss, 1989), birds (Longmire et al., 1991, Miyaki et al., 1993), fishes (Schartl et al., 1993) or even plants (Weising et al., 1991). Especially its application in paternity testing turned to account in many species of animals (Lubjuhn et al., 1991,…
Deciding properties of integral relational automata
1994
This paper investigates automated model checking possibilities for CTL* formulae over infinite transition systems represented by relational automata (RA). The general model checking problem for CTL* formulae over RA is shown undecidable, the undecidability being observed already on the class of Restricted CTL formulae. The decidability result, however, is obtained for another substantial subset of the logic, called A-CTL*+, which includes all ”linear time” formulae.

Current Algebras as Hilbert Space Operator Cocycles
1994
Aspects of a generalized representation theory of current algebras in 3 + 1 dimensions axe discussed. Rules for a systematic computation of vacuum expectation values of products of currents are described. Their relation to gauge group actions in bundles of fermionic Fock spaces and to the sesquilinear form approach of Langmann and Ruijsenaars is explained. The regularization for a construction of an operator cocycle representation of the current algebra is explained. An alternative formula for the Schwinger terms defining gauge group extensions is written in terms of Wodzicki residue and Dixmier trace.

Transfusión autóloga diferida en cirugía primaria de prótesis total de cadera
1994
Se analizan los resultados obtenidos mediante transfusión autóloga diferida (TAD) en 50 pacientes intervenidos de prótesis total primaria de cadera. Las extracciones de sangre se realizaron con una semana de intervalo, transcurriendo al menos 72 horas entre la última extracción y la intervención. El total de unidades extraídas para TAD ha sido 100, transfundiéndose 77, lo que supuso el 91% de la sangre transfundida a estos pacientes. 8 pacientes precisaron la transfusión de 1 unidad de sangre homóloga. No se produjeron reacciones adversas ni durante la extracción ni tras la transfusión y los pacientes recuperaron sus cifras normales de hemoglobina y hematocrito al cabo de 1 mes de la interv…

Toxic Proteins and Peptides
1994
Many animals produce poisonous substances which, even at a relatively low dose, are deleterious or lethal to other organisms, including man. They may serve on the one hand to disable or kill prey, or on the other hand as a protection or defence against predators. These substances are mostly produced by special glands, and both poison reservoirs and specialized structures for delivering the secretion, e.g. stings or modified mouthparts or fangs, are usually also present. In accordance with the aims of this book, we will deal with the comparative biochemistry of the animal toxins as natural products with special structures and functions; a discussion of the mechanisms of their pharmacological…
Souffrir en musique
1994
Suffering to Music - Although, in its relation to suffering, music is generally reputed for possessing therapeutic virtues, several iconographie and written sources dating from the thirteenth to the fifteenth centuries attribute a harmful influence to music. This ambivalence was based on the correlation between the intensity of suffering and that of the sonorous quality of musical instruments, which in the Middle Ages were divided into two great families in accordance to the sound volume they produced. Consequently it was according to their high and strident or low and soft sonorities that the instruments were thought to act on suffering, either amplifying it or alleviating it.
Measurements of the Lineshape of the $Z^{0}$ and Determination of Electroweak Parameters from its Hadronic and Leptonic Decays
1994
Abstract: During the LEP running periods in 1990 and 1991 DELPHI has accumulated approximately 450000 Z0 decays into hadrons and charged leptons. The increased event statistics coupled with improved analysis techniques and improved knowledge of the LEP beam energies permit significantly better measurements of the mass and width of the Z0 resonance. Model independent fits to the cross sections and leptonic forward-backward asymmetries yield the following Z0 parameters: the mass and total width M(Z) = 91.187 +/- 0.009 GeV, GAMMA(Z) = 2.486 +/- 0.012 GeV, the hadronic and leptonic partial widths GAMMA(had) = 1.725 +/- 0.012GeV, GAMMA(l) = 83.01 +/- 0.52 MeV, the invisible width GAMMA(inv) = 51…
Platelet membrane fluidity, platelet membrane lipid pattern and platelet cytosolic Ca2+ content in subjects with vascular atherosclerotic disease
1994
In a group of subjects with vascular atherosclerotic disease (V AD) we examined the platelet membrane fluidity (obtained marking intact resting platelets with TMA-DPH), the platelet membrane cholesteroVphospholipid ratio (CIPL using column chromatography), the platelet membrane individual phospholipids (employing the thin layer chromatography) and the platelet cytosolic Ca2+ content (evaluated marking intact resting platelets with Fura 2-AM). From the obtained data, it is evident that platelet membrane fluidity differentiates normals from V AD subjects. Platelet membrane lipid pattern (CIPL and individual phospholipids) and cytosolic Ca2+ content do not discriminate normals from V AD subjec…

Physical Origin and Biological Significance of Solvent Induced Forces
1994
The notion of solvent-induced forces (SIFs), as distinct from solute-solute forces acting through the solvent, is illustrated in terms of: i) the microscopic space-and time-resolved view provided by Molecular Dynamics Simulations; ii) the standard statistical-mechanical formulation, and iii) the inherent structures of water. It is shown that the origin of SIFs is in the non-additivity of the effects of solute-perturbation on the H-bond network in the solvent. This nonadditivity does not require non-additivity of water-water and solute-water interaction potentials. Two experimental studies, illustrating different aspects of SIFs are discussed in detail. One is the case of Human Adult Hemoglo…
Interferon decreases serum lipid peroxidation products of hepatitis C patients
1994
Abstract Thiobarbituric acid reactive substances (TBARS) concentration in serum has been determined in healthy subjects and in patients suffering acute hepatitis and chronic cases of hepatitis C. Treatment with interferon of the chronic active hepatitis C patients, 5 × 10 6 U three times a week during 2 months, led in those patients whose SGPT activity normalized in serum, to a concomitant decrease in serum TBARS content. The possible theoretical involvement of peroxidation and antioxidants in this beneficial effect of interferon in hepatitis C patients is discussed. The results presented confirm the value of TBARS as laboratory test in the management of liver diseases and as a useful tool …
Influence of ATPase activity on PPi dependent H+-transport in tonoplast vesicles of Acer pseudoplatanus
1994
Abstract Tonoplast H + -ATPase and H + -pyrophosphatase (H + -PPase) were previously characterized in Acer pseudoplatanus cells (A. Pugin et al., Plant Sci., 73 (1991) 23–34; A. Fraichard et al., Plant Physiol. Biochem., 31 (1993) 349–359). The present study concerns the relationships between these two enzymes in vitro. ATP and PPi hydrolysis were additive and the inhibition of one did not affect the activity of the second one. ATP and PPi H + -transports were also additive. The H + -PPase inhibition did not change ATP-dependent H + -transport but H + -ATPase inhibition inhibited the PPi dependent H + -transport. Because H + -PPase was reported to transport H + and K + into the vacuole (Dav…

Untersuchungen zur Photoleitf�higkeit von alkoxysubstituierten Oligo- und Poly(1,4-phenylenethenylen)en
1994
Investigations on the Photoconductivity of Alkoxy Substituted Oligo- and Poly(1,4-phenyleneethenylene)s The photoreactivity and the photoconductivity of the mono- and dialkoxy substituted oligo- and poly(1,4-phenyleneethenylene)s 1/1′a-n were investigated in order to optimize the photoconducting properties of these materials. Increasing the length of the side chains enhances the average length of the main chain during the polycondensation and decreases the band gap till the limit of convergence is reached. The highest photoconductivity was observed for the 2,5-dipropyloxy system 1/1′j. Longer side chains render the charge transfer from chain to chain more difficult. The measurements were pe…
Covalent modificaition of juvenile hormone binding proteins by photoaffinity labeling: An unexpected gel shift effect
1994
The 32 kD juvenile hormone binding protein (JHBP) and two 80 kD proteins in larval Manduca sexta hemolymph were labeled with [3H]FDK, a photoaffinity analog of methyl farnesoate (MF). The labeling could be completely displaced by a 30-fold excess of either MF or JH II, demonstrating that [3H]FDK binds specifically to the JH binding sites of the 32 kD JHBP and the 80 kD proteins. In addition, a high molecular-mass protein was labeled with [3H]FDK; labeling could be displaced by excess MF but not by JH II, demonstrating the selectivity in binding MF. The 32 kD JHBP also appeared to weakly bind the potent juvenoid, methoprene, at the JH binding site. Covalent modification by [3H]FDK induced a …

Control of bulk density and particle size distribution of polyethylene
1994
One of most important properties of polyolefins obtained on Ziegler-Natta type catalysts is the size of polymer grains. From a technological point of view it is desirable to obtain a polymer of the highest bulk density. In this Institute we have studied the bulk density and particle size distribution of olyethylene (PE) obtained on a new titanium-magnesium catalyst. Bulk density and particle size distribution of PE were studied as functions of the supported catalyst composition as well as polymerization time. Results were compared with those obtained on conventional catalysts. It was found that the modification of titanium-magnesium catalysts and the time of polymerization improve the bulk …

High Precision Differential Astrometry in Large Angular Separation Pairs of Radiosources
1994
We show preliminary results of three of the four radiosource pairs with angular separations ranging from 0.01° to 6° where we have determined such a separation with a typical fractional precision of 10-8using phase delays corrected for structural and ionospheric contributions. In the radiosource 4C39.25 we measure a motion with respect to an external radiosource which is compatible with previously reported internal superluminal motion.
