Minimal strong digraphs
Jesús García-López,Carlos Marijuán
Mathematics , 2010,
Abstract: We introduce adequate concepts of expansion of a digraph to obtain a sequential construction of minimal strong digraphs. We characterize the class of minimal strong digraphs whose expansion preserves the property of minimality. We prove that every minimal strong digraph of order $n\geq 2$ is the expansion of a minimal strong digraph of order $n-1$ and we give sequentially generative procedures for the constructive characterization of the classes of minimal strong digraphs. Finally we describe algorithms to compute unlabeled minimal strong digraphs and their isospectral classes.

Open Journal of Animal Sciences (OJAS) , 2012, DOI: 10.4236/ojas.2012.21001
Abstract: Different kind of feed can result in development of new meat odors, aroma and texture. The aim of the study was to use flash profile method to determine differences; if any, in sensory traits of Creole turkey meat with different alimentation programs. Treatments were kitchen leftovers + fresh forage, commercial feed, kitchen leftovers, commercial feed + fresh forage, and broken maize + fresh forage. Cooked thighs, drumstick and breast were used. For the meat evaluation two different groups of people were recruited. In order to perform the sensory profile of breast six persons were recruited, in a second group nine persons; in both cases they did not know what kind of meat they were evaluating. Each sensory profile had three replicas, previously three training sessions and establishment of sensory attributes criteria were held. Attribute discrimination was evaluated one-way ANOVA. To obtain consensus and treatment mean position, attributes of the subjects a Generalized Procrustes Analysis was used and comparison of treatments through an ascendant hierarchy classification. Thirty five different sensory descriptive were generated. There were differences in meat sensory profile, it can be said that different treatments influenced in different ways the muscle development of Creole turkey, creating new sensory attributes.

Abstract: Resuemn El objetivo del estudio fue analizar la influencia de la tecnología de las fotocélulas en el registro de tiempo y su fiabilidad durante de carreras de velocidad de corta distancia. Participaron 25 estudiantes (20.5±0.5 a os; 1.78±0.02 m; 77.5±1.8 kg) que fueron evaluados en 3 días (2 de familiarización y 1 de test). Se registraron aleatoriamente 3 carreras de aceleración y 3 velocidad lanzada, cronometradas simultáneamente a los 5, 10 y 15 m por dos sistemas de fotocélulas DSD Laser System : haz simple y doble haz. El tipo de fotocélulas utilizadas influyó en el tiempo de carrera (F=11.92 y p<0.001) y su fiabilidad (F=14.52 y p<0.001). En la carrera de aceleración el haz simple sobrestimó ~0.02 s el tiempo respecto al doble haz (F=42.95 y p<0.001), obteniéndose registros fiables (CCI > 0.80) a los 10 y 5 m, respectivamente. En la carrera lanzada ambos sistemas midieron prácticamente igual (diferencias de ~0.005 s), obteniendo registros fiables a los 15 y 10 m, respectivamente. En conclusión, en carreras de aceleración la distancia mínima a registrar con haz simple debe ser de 10 m, y de 5 m con haz doble, mientras que en carreras lanzadas deberían utilizarse unas distancias mínimas de 15 y 10 m, respectivamente. Futuros estudios deberían analizar la distancia óptima a la primera fotocélula en las carreras de aceleración, para aumentar la fiabilidad de la medición y facilitar la comparación entre registros de diferentes estudios.Abstract The purpose was to analyze the influence of the timing gates’ technology on both running time performance and its reliability during short sprint distances. Twenty-five physical students participated (20.5±0.5 yr; 1.78±0.02 m; 77.5±1.8 kg), whose were evaluated during 3 separate days (2 familiarization sessions and 1 testing session). Three standing-start and 3 flying-start runs were randomized and simultaneously registered at 5, 10 and 15 m by two timing gates DSD Laser System : single- and dual-beam. The type of timing gates affected the performance (F=11.92 y p<0.001) and the reliability (F=14.52 y p<0.001). During the standing-start runs, the single-beam system overestimated (~0.02 s) the performance with respect to the dual-beam one (F=42.95 y p<0.001), and the reliability was acceptable (CCI>0.80) at the distances of 10 and 5 m, respectively. During the flying-start runs, both systems obtained a very similar registry (differences of ~0.005 s), and the reliability was acceptable at the distances of 15 and 10 m, respectively. In conclusion, during the standing-start runs the minimum distance to registry the p
Phytoclimatic Dynamics of Mediterranean Forests under Climate Change. A Case Study in a Southern European Pinus sylvestris L. Stand  [PDF]

Some effects of climate change on the composition and competitive capacity of southern European Pinus sylvestris L. forests in the Mediterranean basin were evaluated. The variation over the period 1910-2008 through 30-year mobile averages of a Phytoclimatic Suitability Index (PSI) of the main tree species of the forest cover are used to indicate the competitive hierarchy of Pinus sylvestris and Fagus sylvatica L. The methodology was applied at a specific location on the Spanish south-facing slopes of the Pyrenees mountain range in the Iberian Peninsula, where the increase in the average temperature was 1.4?C in the period of observation. The results indicated that the apparent equilibrium between the two species studied changed from the 1934-1963 average. Due to the loss of competitive capacity of Scots pine with respect to European beech, particularly from the years 1970-1999, the model predicted an inversion of the situation as it was up until now, so that beech had a higher PSI than pine. The phytoclimatic approach proposed here offers new methodological horizons for the study of the effects of climate change on the future of the forests.

Abstract: Background: Hereditary angioedema (HAE) is a primary immunodeficiency disorder characterized by C1 complement inhibitor deficiency and unregulated activation of complement. Aspirin hypersensitivity is related to an increase in the amount of leukotrienes with eosinophil and mast cell activation and increased levels of glandular kallikrein with upregulated local conversion of bradykinin. Both conditions can be present in the same patient. Objectives: We present five patients with HAE; they were all being treated in similar ways according to the therapeuthic options available in our institute (danazol). However, three of them had recurrent episodes of angioedema; in these cases, it was identified aspirin hypersensitivity as a cause of poor disease control. A review of the literature is included. Case Presentation: We present the cases of four females and one male (age range 21 - 58 years) with type I HAE. Subjects were all ISSSTE beneficiaries (state workers) treated at the National Medical Center “20 de Noviembre”. Aspirin hypersensitivity was identified in three patients. Elimination of NSAIDs along with dietary elimination of high salicylate-containing foods improved control of angioedema crisis (severe and/ or recurrent episodes). Discussion: Aspirin hypersensitivity was identified as a factor for poor control in our patients with HAE. Such cases improved with dietary elimination of high salicylate-containing foods and avoidance of NSAIDs. Conclusions: This is the first report of patients with HAE and aspirin hypersensitivity as a cause of poor control. We recommend a deliberate search of these comorbidities, especially in cases of poor disease control. Further studies are needed to continue the investigation on this topic.
?L'intérêt légitime? et la notion de réparation des droits fondamentaux
García-López,Luisa Fernanda;
Vniversitas , 2010,
Abstract: le juge doit garantir le droit: c'est sa fonction déterminante. ainsi, il intègre la notion de dommage, avec celle des droits fondamentaux par le biais de l'action de tutelle. garantir la réparation répond a la satisfaction d'un intérêt légitime source de toute réparation. en effet, le juge doit définir les instruments pour assurer la protection du droit fondamental lésé et doit rétablir le droit, autrement, il est dans l'obligation d'ordonner l'indemnisation, qui correspond à la perte économique. en matière de responsabilité extracontractuelle, le juge analyse le dommage du point de vue de la victime et non pas de celle de l'auteur du dommage. le mal étant causé, la victime n'a pas à le supporter. de ce fait, le dommage donne un titre légitime de réparation d'un préjudice d'ordre patrimonial ou extrapatrimonial, collectif ou individuel. l'action de tutelle fait appel à la réparation d'un dommage qui n'est pas d'ordre pécuniaire.

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0032141
Abstract: Introduction Healthcare management is oriented toward single diseases, yet multimorbidity is nevertheless the rule and there is a tendency for certain diseases to occur in clusters. This study sought to identify comorbidity patterns in patients with chronic diseases, by reference to number of comorbidities, age and sex, in a population receiving medical care from 129 general practitioners in Spain, in 2007. Methods A cross-sectional study was conducted in a health-area setting of the Madrid Autonomous Region (Comunidad Autónoma), covering a population of 198,670 individuals aged over 14 years. Multiple correspondences were analyzed to identify the clustering patterns of the conditions targeted. Results Forty-two percent (95% confidence interval [CI]: 41.8–42.2) of the registered population had at least one chronic condition. In all, 24.5% (95% CI: 24.3–24.6) of the population presented with multimorbidity. In the correspondence analysis, 98.3% of the total information was accounted for by three dimensions. The following four, age- and sex-related comorbidity patterns were identified: pattern B, showing a high comorbidity rate; pattern C, showing a low comorbidity rate; and two patterns, A and D, showing intermediate comorbidity rates. Conclusions Four comorbidity patterns could be identified which grouped diseases as follows: one showing diseases with a high comorbidity burden; one showing diseases with a low comorbidity burden; and two showing diseases with an intermediate comorbidity burden.

The relationship between bacterial load and the microalga Chaetoceros muelleri was analyzed in a scale-up experiment. The microalga was grown during five days in a 0.4-L Erlenmeyer flask, 2-L Fernbach flask, 18-L Carboy and 400-L column, during which the cell density of C. muelleri, the abundance of heterotrophic bacteria, Vibrio spp., and total bacteria were determined. The highest specific growth rates (μ) of C. muelleri occurred during the first day of culture (0.88 to 2.29 d-1). Highest cell density was recorded on the fifth day at the 2-L (7.62 × 106 cells·mL-1) and 18-L (6.32 × 106 cells·mL-1), coinciding with the maximum counts of heterotrophic bacteria (16.55 × 105 and >30 × 105 CFU·mL-1, respectively). There was a high correlation (0.80, 0.75, 0.85; p <0.05) between microalgal cell density and total bacteria in the first three culture volumes and a low correlation (0.27; p = 0.34) at 400-L column. The highest mean concentration of total bacteria (884.13 × 105 cells·mL-1) during the five days occurred at 18-L Carboy. The concentration of total bacteria at all levels was always higher than that of heterotrophic bacteria. The average ratio of heterotrophic to total bacteria was higher in the 2-L (0.0108) and 18-L (0.0172) cultures. The high biomass of C. muelleri and the presence of Vibrio spp. at the 18-L and 400-L levels indicate that it is necessary to establish programs to prevent diseases and economic losses caused by pathogenic bacteria in penaeid shrimp farming.
