Sobre ontología jurídica e interpretación del Derecho

Ontologically speaking, my contention is that Law is composed of utterances. These legal utterances are elements that comprise Law and precede interpretative activity. The interpretative activity that addresses such utterances, that is, interpretation of Law, focuses on those designated as <>. Interpretative utterances differ from judicial utterances not only by the fact that the...

Pulsating strings with mixed three-form flux

Abstract Circular strings pulsating in AdS3 × S3 × T 4 with mixed R-R and NS-NS three-form fluxes can be described by an integrable deformation of the one-dimensional Neumann-Rosochatius mechanical model. In this article we find a general class of pulsating solutions to this integrable system that can be expressed in terms of elliptic functions. In the limit of strings moving in...

Role of oceanography in shaping the genetic structure in the North Pacific hake Merluccius productus

Determining the relative influence of biotic and abiotic factors on genetic connectivity among populations remains a major challenge in evolutionary biology and in the management and conservation of species. North Pacific hake (Merluccius productus) inhabits upwelling regions in the California Current ecosystem from the Gulf of California to the Gulf of Alaska. In this study, we...

Homogeneous Oxidation of Volatile Nitrogen (NH3, HCN) to Nitrogen Oxides: A Modeling Study of the Effect of Alkali Vapors

The effect of alkali vapors in the combustion of different types of Scandinavian fuels, i.e. Finnish black liquor, Swedish wood and Danish straw, was studied based on detailed chemical kinetic modeling. Two H/C/O/N/Na/K mechanisms consisting of about 350 reactions between 60 chemical species were utilized and validated with available experimental data from the literature. The...

Operational Losses for the Capital Charge of Health Insurers: Lessons from Spain

The new legislation in the insurance sector within the European Union, Solvency II, which represents an important milestone for the management and financial analysis of operational risk, will have a positive impact on their knowledge and control. This research explores the statistical analysis of the operational risks of health insurance companies in Spain from an external...

STATegra EMS: an Experiment Management System for complex next-generation omics experiments

High-throughput sequencing assays are now routinely used to study different aspects of genome organization. As decreasing costs and widespread availability of sequencing enable more laboratories to use sequencing assays in their research projects, the number of samples and replicates in these experiments can quickly grow to several dozens of samples and thus require standardized...

Increased levels of prolactin receptor expression correlate with the early onset of lupus symptoms and increased numbers of transitional-1 B cells after prolactin treatment

Background Prolactin is secreted from the pituitary gland and other organs, as well as by cells such as lymphocytes. Prolactin has an immunostimulatory effect and is associated with autoimmune diseases that are characterised by abnormal B cell activation, such as systemic lupus erythematosus (SLE). Our aim was to determine if different splenic B cell subsets express the prolactin...

Inhibitory effect of c-Myc on p53-induced apoptosis in leukemia cells. Microarray analysis reveals defective induction of p53 target genes and upregulation of chaperone genes

We have previously demonstrated that c-Myc impairs p53-mediated apoptosis in K562 human leukemia cells, which lack ARF. To investigate the mechanisms by which c-Myc protects from p53-mediated apoptosis, we used K562 cells that conditionally express c-Myc and harbor a temperature-sensitive allele of p53. Gene expression profiles of cells expressing wild-type conformation p53 in...

Terazosin: Ex vivo and in vitro platelet aggregation effects in patients with arterial hypertension

Antihypertensive effect, platelet aggregation, and plasma lipid profile were studied in a group of 14 hypertensive patients with diastolic blood pressure between 96 and 116 mm Hg during placebo and terazosin phases. Terazosin, an α1-adrenergic blocking agent, was given initially at the dosage of 1 mg daily. Then it was continued at a dosage of 2 mg daily and 5 mg daily...
