Abstract: Objetivo. La medición del asma, la rinitis y el eczema ha sido motivo de controversia metodológica por la falta de uniformidad en los diagnósticos operacionales. Con el fin de probar la aplicabilidad de una metodología estandarizada para comparaciones en tiempo y espacio se determinó la prevalencia del asma y de otras enfermedades alérgicas en una muestra aleatoria de escolares (n= 6 238) de 6 a 8 a os y de 11 a 14 a os residentes de Cuernavaca, Morelos, México. Material y métodos. Se aplicó la metodología propuesta por el International Study of Asthma and Allergies in Childhood (ISAAC) para determinar la prevalencia y severidad del asma, la rinitis y el eczema. La información de prevalencia tanto actual como acumulada para dichos padecimientos se obtuvo a través de un cuestionario estandarizado contestado por los padres de los ni os. Resultados. La prevalencia acumulada de asma por diagnóstico médico y sibilancia fue de 5.8% (5.2-6.4) y 21.8% (20.7-22.9) respectivamente; la prevalencia de sibilancia en los últimos 12 meses fue de 8.9% en el grupo de 6 a 8 a os contra 6.6% en el de 11 a 14 a os, p< 0.001. La prevalencia de diagnóstico médico de rinitis fue de 4.9% (4.3-5.5). Con relación a los síntomas típicos de rinitis, en los últimos 12 meses la prevalencia fue de 9.6% (6 a 8 a os) y de 10.1% (11 a 14 a os). La prevalencia de eczema por diagnóstico médico fue de 4.1% (3.6-4.6). La prevalencia de síntomas de eczema en los últimos 12 meses fue de 10.1% (6 a 8 a os) y de 10.6% (11 a 14 a os). Los síntomas severos de asma fueron significativamente más prevalentes en el grupo de 6 a 8 a os y en los meses de oto o. Conclusiones. La prevalencia de asma tanto por diagnóstico médico como por síntomas resulta relativamente baja en relación con otros estudios realizados con la misma metodología. Se analizan las bondades del uso de una metodología estandarizada.

Acta Scientiarum : Human and Social Sciences , 2007,
Abstract: O artigo aponta a relevancia da coopera o interuniversitária e prop e um modelo visando estimular o intercambio científico e tecnológico entre as universidades do Sistema Público Estadual paranaense. Tem como pressupostos as bases teóricas e epistemológicas da institucionaliza o, estrutura e comportamento que formam asorganiza es em geral e as universitárias em particular. Utilizou-se a abordagem humanista da pesquisa qualitativa, de caráter histórico-longitudinal, que pode ser delineado como um estudo multi-caso, marcadamente de cunho descritivo e interpretativo. Os resultadosencontrados indicam a possibilidade de haver forte consistência entre os fatores institucionalizantes identificados em cada universidade e o seu conjunto na proposi o de um modelo de coopera o interuniversitária, a partir da perspectiva conceitual das ciênciasadministrativas. Conclui-se que as universidades, quando observadas, cada uma, individualmente, ou no seu conjunto, apresentam - pela sua evolu o e estágio já alcan ados, - forte aderência para participar, construir e manter, a partir do modelo proposto, um sistema de coopera o interuniversitária articulado e sustentável. The article points to the relevance of cooperation and proposes a model seeking to stimulate the scientific and technological exchange among public universities in the state of Paraná. It is supported on the theoretical and epistemological frameworks of institutionalization, structure and behavior that formorganizations in general, and higher education ones in particular. The humanist approach for qualitative research was used, of a historical-longitudinal character, which can be outlined as a multi-case study of remarkably descriptive and interpretative character. The results obtained indicate the possibility of strong consistence among the institutionalization factors identified in each university and their totality for the proposition of a model of interuniversity cooperation, based on the conceptual perspective of the administrative sciences. It concludes that the universities, when observed either individually or as a group, they present – due to their already-achieved levels of evolution – displayed strong cohesion to participate, build and maintain an articulate and sustainable system of inter-university cooperation, starting from the proposed model.

Define and understand the process of institutionalization of universities and their change is a relevant subject. The present study aimed to identify, study and present, - from the perception of key informants - the strategies used in the institutionalization of public universities in Paraná State. Thus, we adopted the subjective conception of the environment, based on contributions from Institutional Theory, Strategy and social actors. Regarding the methods, the research was characterized as qualitative, descriptive and sectional with longitudinal perspective, developed through a case study. Survey data were gathered in primary and secondary way. The analysis of interviews and their results indicate that: (a) possibility of adhesion between the strategies used and their achievement in the form of institutionalization of public universities from Paraná State during the period when the key informant was the head of the institution, (b) adhesion between action and resul
Analysis of Nutritional Constituents in Twenty Citrus Cultivars from the Mediterranean Area at Different Stages of Ripening  [PDF]

Abstract: Twenty Citrus cultivars grown in the Mediterranean climate were analysed at different stages of fruit maturity to determinate changes in organic acids, vitamin C and sugars. High-performance liquid chromatographic methods were used to identify and quantify of these compounds. The influences of variety, rootstocks and different stages of fruit maturity were observed. Generally, the vitamin C content was higher in varieties grafted on Troyer citrange that the corresponding cultivars grafted on Cleopatra mandarin. At commercial harvest stage, lemons, clementine mandarins and sweet oranges, showed the highest concentrations of vitamin C; citrons, limes and lemons, the higher amounts of organic acids; and mandarins and hybrids the highest amounts of sugars. Since sugars and acids played an important role in fruit flavor and their nature and concentration largely affect taste characteristic and organoleptic quality, we hope to relate genotypes and differences in final fruit quality. We have found clear differences in the content of sugars, ascorbic and organic acids for the different groups in agreement with the Citrus classification. Also climatic and cultural factors have affected to fruit quality, and anticipate or delay the collection generally results in a loss of bioactive compounds. The fruit quality was affected differently and we have observed differences in accordance with the rootstocks used but, the major differences in nutritional composition must be attributed mainly to genetic factors. The data presented are an important factor to chose varieties with a high potential as nutraceutical source.
The Pendulum of Dynamic Interactions  [PDF]
Julio Cano Lacunza
Journal of Applied Mathematics and Physics (JAMP) , 2015, DOI: 10.4236/jamp.2015.39146
Abstract: In this paper, we present evidence to show that the dynamics of rigid solid bodies is not a closed discipline, particularly in the field of rotational dynamics. From the observation of bodies with intrinsic rotation in our universe, our research group proposes new dynamic hypotheses that explain the behaviour observed when these bodies are subject to new simultaneous non-coaxial rotations. A new gyroscopic conical pendulum was designed for this purpose. Experimental tests initially conducted with this new gyroscopic conical pendulum were repeated for their recording on video, which accompanied this paper for better understanding thereof. These experimental tests positively confirm the new Theory of Dynamic Interactions, and its dynamic laws, which help us to understand the behaviour of this pendulum and, in general, that of the baryonic mass when it is subject to non-coaxial simultaneous rotations. It thus provides a better understanding of the nature and the dynamic behaviour of our universe.
Simple Adaptive Delta Operator Aircraft Flight Control for Accommodation of Loss of Control Effectiveness  [PDF]
Alfredo Cano, Kenneth Sobel
Engineering (ENG) , 2016, DOI: 10.4236/eng.2016.84016
Abstract: A new proof for stability of delta operator simple adaptive control is presented in terms of a set of Linear Matrix Inequalities (LMIs). The paper shows how to design a feedforward gain to satisfy the LMIs over a polytope of loss of control effectiveness failures. The MATLAB Robust Control Toolbox is used to find the feedforward gain with the smallest norm that satisfies the LMIs. Examples are presented of the F/A-18 aircraft and the Innovative Control Effectors (ICE) tailless aircraft that show the design of a feedforward gain for a loss of control effectiveness in any one control effector. The designs use a fixed eigenstructure assignment controller for an inner loop augmented with the simple adaptive controller. Simulations of both aircraft include simultaneous loss of control effectiveness failure and lateral wind gust. Simulation results for the F/A-18 aircraft show that the adaptive controller achieves almost perfect tracking whereas the nonadaptive controller cannot achieve a coordinated turn when an aileron failure occurs. The ICE tailless aircraft uses sideslip, washed-out stability axis yaw rate, and stability axis roll rate feedback for both the inner loop eigenstructure assignment controller and the simple adaptive controller. However, the adaptive controller also uses bank angle feedback. Simulation results for the ICE tailless aircraft show that the adaptive controller achieves almost perfect tracking whereas the nonadaptive controller diverges when an all moving tip failure occurs.

American Journal of Climate Change (AJCC) , 2014, DOI: 10.4236/ajcc.2014.32021
Abstract:

This study analyses the physical factors of the Palestinian bioclimate, the mean monthly and annual temperature, mean monthly maximum temperature, and mean monthly minimum temperature using data from six weather stations from the Palestine Meteorological Department, recorded in two periods: The first period from 1969 to 1981, the second period from 1975 to 1995 (more than 32 years). Statistical tests included a bioclimatic analysis of Palestinian meteorological stations for the periods from 1969-1981 and 1975-1995 by using bioclimatic classification of the Earth of Rivas Martinez Salvador, with regard to thermicity index, compensated thermicity index, annual ombrothermic index, and simple continentality index. The bioclimate of Palestineis affected by various factors, such as the Jordanian-Syrian desert, and its natural geography and topography, among others as well as biodiversity. Annual ombrothermic index value ranging between 0.6 to 3.4 and simple continentality index was from 12.4 to 18.1. It is concluded that the occupied Palestinian territories belong to the arid, semiarid, dry, sub-humid and humid ombrotype, and the Inframediterranean, Thermomediterranean and Mesomediterranean bioclimatic belt.

Rain Forests in Subtropical Mountains of Dominican Republic  [PDF]

American Journal of Plant Sciences (AJPS) , 2014, DOI: 10.4236/ajps.2014.510161
Abstract:


This article presents a study of the cloud forest dominated by the Prestoea montana (R. Graham) Nichols. This is a hyperhumid forest located in ravines and shaded areas with cloud condensation, and at heights ranging from 350 - 1250 masl. This type of forest is always found in thermal and mesotropical belts, without ever reaching the supratropical belt. This study was based on works published by other authors and on our own field sampling. The article begins by describing the geological, bioclimatic, biogeographic and floristic aspects of the areas in the study, specifically the hyperhumid areas in the central and eastern mountains. Due to the scarcity of phytosociological works on this area, we apply a statistical treatment to compare our communities with other associations described in Cuba. This comparison reveals that these forest groups are floristically quite distant from each other, both with regard to alliance and association species. We therefore propose two new communities: Cyathea furfuracea Baker and Prestoea montana (Grah.) Nichol; Ormosia krugii Urb. and Prestoea montana (Grah.) Nichol.


Bench-to-bedside review: Glucose production from the kidney
No?l Cano
Critical Care , 2002, DOI: 10.1186/cc1517
Abstract: Data obtained from net organ balance studies of glucose production lead to the classic view according to which glucose homeostasis is mainly ensured by the liver. Hence, these studies concluded that renal glucose production only plays a significant role during acidosis and prolonged starvation. These data were not in accordance with some clinical and biochemical evidence.As a matter of fact, blood flow and gluconeogenic-enzyme equipment in the renal cortex are compatible, with a gluconeogenic activity similar to that of the liver [1]. Moreover, renal failure was shown to be the first cause of hypoglycemia after insulin therapy [2], suggesting the importance of this organ in blood glucose regulation.The magnitude of renal glucose release and its role in various physiological and pathological circumstances were recently reconsidered in the light of new data on renal glucose release and uptake obtained by the combination of systemic and renal glucose arteriovenous balance and deuterated glucose dilution. These data now conduce one to consider that renal gluconeogenesis substantially participates in postabsorptive glucose production and that its role in adaptation is of first relevance. The present paper refers to recently published reviews on this topic [1,3].Glucose oxidation accounts for 50% of energy expenditure during the postabsorptive phase. Eighty percent of glucose utilization is located in insulin-insensitive tissues (mainly the brain) and the remaining 20% in insulin-sensitive tissues. Glucose requirements after an overnight fast are ensured by endogenous glucose production, which is approximately 10–11 μmol/kg/min [1]. According to data obtained from net organ balance studies of glucose production, the liver was considered the quasi-exclusive site of glucose production. As a matter of fact, net renal balance of glucose studies in healthy humans showed little or no net glucose release by the kidneys [4,5,6]. As a consequence, hepatic glucose production was co
