The theory of informal transactions in bureaucracies: some qualifications
1986
The ambition of the paper is certainly not to change substantially Breton and Wintrobe‘s story. We can be sure that many of the differentpieces that they have forged and assembled in their book v ill be replaced or modified in the course of time. This is the fate of all interesting theories. But only time-consuming and collective efforts can achieve this. The only ambition of this paper is a small beginning in that direction. Section II of the paper compares some of the mechanisms, others than trust, vhich have been proposed to explain self-enforcing exchanges. Then, Breton 8nd Wint robe's modelling of trust and trust accumulation is looked at critically in Section III. Section IV presents …

Innovationsschübe durch Außenseiter: Das Beispiel des Amateur-Astronomen William Herschel
1986
Innovatory advances by outsiders: The example of the amateur astronomer William Herschel. — Every scientific experience and perception has been gained from within a particular historical situation constituted by numerous components, both internal and external to a particular science, called praesentabilia (Prasentabilien). They enable and determine the scope and the experiental pale of any given science as well as its way and method of acquiring experience and knowledge. The interaction of such praesentabilia forms, what may be called the Historische Erfahrungsraum (‘historical field of experience’), which each individual and/or (greater/smaller) group shares in respectively. A scientific (…

Differential polyadenylation pattern of ovalbumin precursor RNAs during development.
1986
The expression of the ovalbumin gene encoding for the major hen oviduct protein slows down with age. Analysis of Northern blots of electrophoretically separated total and poly(A) + RNA from oviducts of hens of different age with an ovalbumin-specific probe (nick-translated 9.5 kb ovalbumin gene DNA cloned into pBR322) revealed that the largest high molecular weight ovalbumin RNA precursor (7.9 kb band, representing the putative primary transcript of the ovalbumin gene) was most intense if total RNA from non-egg-laying old hen oviduct was checked as compared to that from egg-laying mature animals. On the other side, the 7.9 kb RNA precursor band was readily detected in the poly(A) + RNA from…

La estructura por edades de la población valenciana: Estudio comarcal
1986
La estructura por edades de la población del País Valenciano presenta profundas disparidades comarcales. La situación se relaciona especialmente con las corrientes migratorias que han afectado de forma contrapuesta al territorio valenciano. Los resultados permiten distinguir estructuras con un importante volumen de población joven, especialmente en las zonas costeras y en el sur del País, frente a comarcas envejecidas sobre todo interiores. Ello lleva consigo problemas diferentes en cuanto a la dinámica demográfica y actividad laboral.

Training-induced changes in neuromuscular performance under voluntary and reflex conditions.
1986
To investigate training-induced changes in neuromuscular performance under voluntary and reflex contractions, 11 male subjects went through heavy resistance (high loads of 70-120% of one maximum repetition) and 10 male subjects through explosive type (low loads with high contraction velocities) strength training three times a week for 24 weeks. A large increase (13.9%, p less than 0.01) in voluntary unilateral maximal knee extension strength with only slight and insignificant changes in time of isometric force production were observed during heavy resistance strength training. Explosive type strength training resulted in a small insignificant increase in maximal strength but in considerable…

Pre- and Postsynaptic Effects of Muscarinic Antagonists in the Isolated Guinea Pig Ileum
1986
Several compounds have been claimed to differentiate between subtypes of muscarinic receptors (2). In the experiments described in this chapter we have studied in the guinea-pig ileum whether the presynaptic muscarinic receptors of the cholinergic nerves differ from the postsynaptic muscarinic receptors of the longitudinal muscle in their affinities for several muscarinic antagonists (methylatropine; trihexyphenidyl; clozapine; DAMP). Inhibition by oxotremorine of the evoked release of acetylcholine (ACh) was used as a parameter of presynaptic activity, and the increase by oxotremorine of smooth muscle tension as a postsynaptic parameter. The affinity constants (pA2 values) of the antagonis…
Aproximación al sistema impositivo de la Generalidad: el tall del drap en el área alicantina (siglos XIV y XV)
1986
La clasificacion de los impuestos puede hacerse, al menos, desde dos puntos de vista: en base a la titularidad o al concepto. La viabilidad de la primera ha sido puesta en crisis por algunos autores que se inclinan por la segunda (1). La utilidad de esta ultima es, a nuestro juicio, indudable, pero requiere, en el confuso panorama de los impuestos medievales valencianos, una definicion previa de los conceptos impositivos que permita la mencionada clasificacion.

An inherited deficiency of the third component of complement, C3, in guinea pigs
1986
Hereditary deficiency of the third component of complement, C3, is found very seldom in the human. C3 deficiency is associated with severe bacterial infections revealing the central role of C3 in complement activation via the classical or alternative pathway. We describe a new hereditary C3 deficiency in strain 2 guinea pigs. Serum from these animals had a markedly reduced lytic activity in a standard assay for complement-dependent, antibody-mediated cytotoxicity. In functional assays of individual components, the hemolytic activity of the components C4, C2, C5 and of factors B, D and H was in the normal range. The functional C3 titer, and similarly C3 antigenic activity in the serum of the…

Aspectos citoquímicos y morfométricos de la fibrosis glútea
1986
Los autores realizan un análisis de los hallazgos anatomopatológicos y valores cuantitativos obtenidos aplicando las técnicas de histoquímica y morfometría en 9 casos de fibrosis glútea. Entre las lesiones descritas se cita una atrofia muscular de las fibras tipo I con hipertrofia de las fibras tipo 2B y distintas modificaciones celulares que representan una alteración primaria de la fibra muscular.
Veure i errors visuals
1986
Tractaré en aquest article d'un problema que ha preocupat últimament als filòsofs: el veure. I dic el veure, ja que, tot i haver-se parlat, debatut i polemitzat sobre la percepció, aquesta ha quedat sempre reduïda en la majoria dels estudis a la percepció merament visual; entre altres coses, per ser Ja que compta amb major tradició epistemològica. Parlaré, doncs, del veure. I ho faré tot oposant-me a una teoria, el fenomenisme, que és ja antiga i que ha estat reiteradament criticada, encara que no sé si refutada. De fet, els filòsofs s'han preocupat més de rebatre aquesta positura que no pas d'hoferir-hi alguna alternativa. Potser perquè l'alternativa consistesca en seguir pa…
Effect of Electrical Stimulation on Denervated Muscle
1986
The possibilities of noninvasive treatment in peripheral nerve injuries are limited. Although it is well known that the severance of a nerve results in paralysis of the dependent tissue, the methods of treating a denervated muscle are still controversial. The most obvious result of denervation is muscle atrophy and paralysis. In 1841 Reid forced the denervated muscle to contract by electrical stimulation to replace the loss of activity and observed that this treatment retarded atrophy. Since then, there has been continuing interest in preventing muscle atrophy with electrotherapy. Peripheral nerve injuries in the two world wars were, for instance, extensively treated with electrical stimula…

Acute Effects of Mechanical Vibration
1986
We know that man possesses a highly developed ability to adjust to different environmental conditions. For this function there are physiological regulatory systems, which release reactions in him for protection against such influences. Thus, receptors for light, smell, taste, temperature, sound, touch, position change, pressure, and tension are at hand which, as parts of the cybernetics system, can release physiologically meaningful protective reactions.
Skyrme-force parametrization: Least-squares fit to nuclear ground-state properties.
1986
We investigate systematically the possibilities and the limits of the Skyrme force for reproducing nuclear ground-state properties in a spherical Hartree-Fock calculation. This investigation is performed by means of least-squares fits of the force parameters to the measured binding energy, diffraction radius, and surface width of eight selected nuclei. Particular emphasis is put on the density dependence of the interaction, which turns out to be determined mainly by the surface width. The least-squares fitting procedure yields the best-fit parameters together with uncertainties on them, and it also allows one to estimate the uncertainties of an extrapolation to other fields, e.g., nuclear m…
Conformation of a chain polyelectrolyte in solution with low molecular weight salt: small angle neutron scattering measurements
1986
Small angle neutron scattering measurements have been carried out on the tetramethylammonium salt of the polystyrenesulfonic acid withDP w =310 and 1060 in water solution with tetramethylammonium chloride with ionic strength between 0.02 M and 1.0 M. The scattering curves in the scattering vector range 0.05 nm−1≤Q≤1.8nm−1 have been fitted using the form factor of a worm-like chain of finite thickness. The conformational parameters mean square radius of gyration, statistic chain element, mass per unit length and mean square radius of the cross-section have been determined experimentally and used for describing the conformation of the coils. By these molecular weights and ionic strengths, exc…

Muscarinic Receptor Activation Increases Efflux of Choline from Isolated Heart and Rat Cortex in Vivo. Interactions with Forskolin and IBMX
1986
Muscarinic receptor activation modulates functions of the heart and neurotransmission in the peripheral and central nervous system. Moreover, muscarinic agonists produce changes in the metabolism of, for example, heart tissue, such as inhibition of beta-adrenoceptor-mediated cAMP accumulation, glycogenolysis and lipase activation.
