PCR-Typing of the Human HLA-DQα Locus: Population Genetics and Application in Forensic Casework

1991

Multi- and single-locus probes recognizing highly polymorphic DNA sequences throughout the genome ([1–3]; C. Rittner, this volume) have become powerful tools for paternity testing and forensic stain analysis. In forensic casework, however, DNA probe technology can often not be applied, since genomic DNA extracted from stain material exposed to conditions of high temperatures and humidity is degraded. Also, the amount of DNA to be typed may not be sufficient to use DNA probe technology, e.g. if extracted from minute blood or sperm stains, from single hairs or from cell smears on microscope slides.

Growth of Domains and Scaling in the Late Stages of Phase Separation and Diffusion-Controlled Ordering Phenomena

1991

These lectures consider the kinetics of phase changes, induced by a sudden change of external thermodynamic parameters. E.g., we treat a system with a second-order transition at a critical temperature Tc (Fig. 1, left part). For T0 > Tc the system is disordered, while for T < Tc there is an order parameter ± ψ (implying one-component orderings, e.g., an Ising model; later we discuss generalizations). We consider a “quenching experiment”: The system is brought from an initially disordered state at T0 to a state at T where in equilibrium the system should be orderedl. Since no sign of ψ is preferred, the system starts forming locally ordered regions of either sign, separated by domain walls. …

Aggregation in Input–Output Tables: How to Select the Best Cluster Linkage

1991

In this paper we try to give a solution to the aggregation problem on working with Input–Output tables. First of all we verify the degree of similarity among the production functions of the industries which aggregate in each sector. Secondly, once we have established the aggregation by using different cluster analysis, we set a number of conditions required to choose the proper linkage method that allows us to characterize the process of aggregation (weighted or unweighted) of the input–output table.

Survey on polarization observables in deuteron photodisintegration below pion-production threshold

1991

Polarization observables of deuteron photodisintegration with polarized photons and oriented deuterons are systematically investigated below π-production threshold with respect to their sensitivity to subnuclear degrees of freedom and relativistic effects, to the different electric and magnetic multipole contributions, and to various realistic potential models. In particular, a complete survey on all single- and double-polarization observables like beam and target asymmetries of the differential cross section, nucleon polarization and proton-neutron spin correlation is given.

Symptomatology and Diagnosis of Benign Prostatic Hyperplasia

1991

The symptoms of benign prostatic hyperplasia are well known. Diagnosis rests on digital palpation of the enlarged prostate. Objective parameters are laboratory tests, imaging techniques, endoscopy, and urodynamic investigations. Laboratory tests include urinalysis and serum creatinine measurement. Markers are not reliable and the determination of acid phosphatase and prostate-specific antigen is not recommended routinely for patients with prostatism. Imaging techniques are usually restricted to a complete echographic investigation of the entire urinary tract. Endoscopic manipulations are seldom necessary. Uroflow measurements are customarily performed, but the need for a complete urodynamic…

Elements of Significance Testing with Equivalence Problems

1991

AbstractThe paper outlines an approach to the general methodological problem of equivalence assessment which is based on the classical theory of testing statistical hypotheses. Within this frame of reference it is natural to search for decision rules satisfying the same criteria of optimality which are customarily applied in deriving solutions to one- and two-sided testing problems. For three standard situations very frequently encountered in medical applications of statistics, a concise account of such an optimal test for equivalence is presented. It is pointed out that tests based on the well-known principle of confidence interval inclusion are valid in the sense 1 of guaranteeing the pre…

La paradoja de la emigración mora en Valencia durante el siglo XV: expatriación musulmana en época de Honorat Mercader (1467-1481)

1991

Desde el acopio de numerosos datos, rigurosamente ensamblados, se busca la explicación a la profunda contradicción que presidió las relaciones entre cristianos y musulmanes a fines de la Edad Media, especialmente en Valencia, donde los grupos políticos dominantes parecen oponerse a la emigración voluntaria musulmana hacia tierras de Granada o Berbería y, sin emabrgo, el flujo de los que salieron nunca cesó e incluso contaron con la ayuda, licencia y permiso de máximas autoridades del aparato administrativo real, en contradicción directa con la letra y el espíritu de la ley. Desentrañar este intrincado acontecimiento es tarea que ha supuesto el acopio de cuantas noticias dispersas se han pod…

Appropriateness between physical space and multicentre economic space in localization problems

1991

Location models are constructed in mathematical economic spaces whereas people locate themselves in real or physical spaces. If economic spaces are multicentric ones, their properties are different from physical spaces. We say that these two spaces are not symmetric. Hence, mathematical location model can lead to an optimal location solution which doesn't' exist in physical space. But, if we admit that an optimal location solution owns more or less to a function of demand of location, we can resolve this question. Then, fuzzy demand functions of location are defined in multicentric spaces and an illustration of this concept is presented.

La evolución de la comedia urbana hasta el Index prohibitorum de 1559

1991

Estudio sobre la evolución de la comedia española desde Torres Naharro hasta el año 1SS9, en que se publicó el Index Prohibitorum, que marcó un cambio en la trayectoria del teatro nacional, desapareciendo al menos de la circulación una multitud de obras teatrales que fueron determinantes en la evolución del drama profano en la Península. Se pasa revista ante todo a la comedia urbana, a la que Crawford denominaba Comedia Romántica o de Costumbres: obras como las anónimas Ypólita, Farsa a manera de tragedia, Auto de Clarindo, y autores como Jaime Huete, Agustín Ortiz, Juan Uceda de Sepúlveda, Martín de Santander, Francisco de Avendaño, Luis de Miranda.

1991

Ce texte se propose de réunir quelques arguments en faveur de la reconnaissance du rôle de la théorie du capital humain dans les progrès de l'analyse du fonctionnement du marché du travail. Au niveau le plus élémentaire, la théorie du capital humain a suscité une confrontation théorique et empirique centrée sur l'analyse des déterminants des gains qui a permis une relance de l'intérêt des économistes pour les phénomènes liés au marché du travail. Plus fondamentalement, la mise à jour des particularités du capital humain et notamment de son incorporation à la personne, a ouvert un vaste champ d'investigation dans lequel se sont inscrites la plupart des analyses économiques actuelles des phén…

A query language for medical statistical analysis

1991

While standard query languages support primarily the definition of single queries, in the evaluation of medical studies one usually formulates large sets of interdependent queries. A set of this type is called an integrated transaction. Our system for the definition of integrated transactions is based on the observation that in medicine a large number of statistical evaluations is founded on a conceptional model that can be structured as a tree. We describe a screen oriented tree editor for the relational data base system DBase and report on our experience with its application in the evaluation of the success rate of PTCA interventions.

A parallel splitting up method and its application to Navier-Stokes equations

1991

A parallel splitting-up method (or the so called alternating-direction method) is proposed in this paper. The method not only reduces the original linear and nonlinear problems into a series of one dimensional linear problems, but also enables us to compute all these one dimensional linear problems by parallel processors. Applications of the method to linear parabolic problem, steady state and nonsteady state Navier-Stokes problems are given. peerReviewed

Phenomenological Paths to Metaphysics

1991

Fifty years after Husserl’s death it is becoming more necessary than ever to give deep thought to the fundamental aspirations of his phenomenology: to lay the foundations of philosophy as opposed to that naturalist, positivist, and objectivist rationality which leads to relativism and skepticism. Husserl’s attempt to create a first philosophy as a framework for philosophical rationality, by itself enough with which to conduct human life, should be reconsidered, since yet again we are living in a cultural situation where the power of facts prevails over the force of reason.

Effect of isoprinosine on IL-2, IFN-γ and IL-4 production in vivo and in vitro

1991

The effects of an immunopotentiating drug, isoprinosine, on the splenocytes of BALB/c mice to produce cytokines were investigated. Isoprinosine enhanced IL-2 production, upregulating the expression of IL-2 receptor in vitro. It also significantly increased the IFN-gamma secretion and decreased the IL-4 production in vivo. The significance of these findings in terms of immune regulation is discussed.

119Sn-NMR Study on Bis(Tri-Butyltin)oxide Derivatives of Phenolic Compounds

1991

Abstract 119Sn-NMR spectroscopy has been utilized in the characterization of various phenolics as their bis(tri-butyltin)oxide, TBTO, derivatives. The present method has been applied both for determination of simple model compounds and for characterization of complex biopolymeric material originating from spent bleach liquor fractionated by an ultrafiltration technique. Based on the large range of 119Sn-NMR chemical shifts of TBTO derivatives of the phenolic compounds and the similar relaxation properties of 119Sn nuclei located in those derivatives, both qualitative and quantitative analytical conclusions can be drawn.
