Martín,Unai; Esnaola,Santiago; Audicana,Covadonga; Bacigalupe,Amaia;
Revista Espa?ola de Salud Pública , 2011, DOI: 10.1590/S1135-57272011000500006
Abstract: background: the estimation of the impact of morbidity on health is essential to health planning. the objective was to estimate this impact using disability free life expectancy, and to analyze whether the hypothetical elimination of various diseases would have led to a compression or expansion of morbidity. methods: cross-sectional study on the population of the basque country. data on mortality (2002-2006), health survey data (2007) and population based data were used. the impact of different groups of diseases on mortality rates, years of life and potential years of life lost (pyll) and disability (absolute number and rates) were calculated. an integrated analysis was also done, using disability free life expectancy (dfle), using the sullivan method. results: the diseases causing the greatest impact on mortality were tumours among men (35,2% and 39,3% of deaths and pyll respectively), and circulatory diseases (34,5% of deaths) and tumours (43,6% of pyll) among women. osteomuscular diseases had a major impact on disability, causing the 26,6% and the 45,2% of the total cases in men and women). circulatory diseases had the highest impact as a whole (4.2 years of dfle in men and 3.8 in women). however, osteomuscular diseases had the highest influence on years of life with disability. conclusions: the diseases which caused the overall greatest impact on mortality and disability were circulatory system related ones, tumors, and osteomuscular diseases. the elimination of this last group of diseases would have led to a morbidity compression, meaning the greatest reduction in life years with disability among all the causes.

Gaceta Sanitaria , 2006, DOI: 10.1590/S0213-91112006000100004
Abstract: objectives: to describe socioeconomic inequalities in mortality in the basque country, using mortality and socioeconomic data by census sections. methods: mortality and population data were obtained from the basque institute of statistics. socioeconomic characteristics of the census sections were assigned to each death and a deprivation index combining information from four socioeconomic indicators was computed. age-adjusted mortality rates by sex, age group (0-64 ≥ 65) and cause of death were calculated for each quintile of the deprivation index. poisson regression models were fitted to estimate age-adjusted rate ratios and excess mortality attributable to inequalities. results: mortality showed a gradient according to the deprivation index in men and women. mortality was greater in the most deprived sections. mortality inequalities were observed in men younger than 65 years. a total of 9.3% of deaths in men and 4.9% of those in women were attributable to socioeconomic inequalities. the relative importance of the cause of death differed according to the inequality measure used. lifestyle-related causes of death were notable. conclusion: this study illustrates the potential utility of census section socioeconomic indicators both to describe socioeconomic inequalities in mortality and to identify priorities for interventions.
Chronic Urticaria Due to Allergy to Wheat Alpha-Amylase Inhibitor Proteins  [PDF]

Case Reports in Clinical Medicine (CRCM) , 2016, DOI: 10.4236/crcm.2016.54024
Abstract: Chronic spontaneous urticaria (CSU) is defined as the spontaneous appearance of wheals, angioedema, or both, for at least 6 weeks, due to known or unknown causes [1]. In some patients who present a CSU with daily or almost daily symptoms a type I allergy could be the underlying cause. We present one adult patient with chronic urticaria who was finally diagnosed as a non-occupational case of IgE-mediated wheat allergy manifested following exposure by 3 different routes: inhalation (rhinitis and bronchial asthma), dermal absorption (contact urticaria) and ingestion (systemic chronic urticaria). We were able to detect the culprit proteins by immunoblotting. Serum IgE binds mainly to alpha-amylase/trypsin inhibitors and, to a lesser extent, to other proteins associated with food allergy to grains (e.g. beta-glucanase, serpin, peroxidase). In our opinion, skin prick tests with a food standard battery could help in the etiological diagnosis of chronic urticaria. The identification of responsible allergens could be difficult because only a few complex in vitro techniques allow detecting the allergy to several proteins.
Modeling Agricultural Change through Logistic Regression and Cellular Automata: A Case Study on Shifting Cultivation  [PDF]
Santiago Lopez
Journal of Geographic Information System (JGIS) , 2014, DOI: 10.4236/jgis.2014.63021

Agricultural expansion is one of the prime driving forces of global land cover change. Despite the increasing attention to the factors that cause it, the patterns and processes associated with indigenous cultivation systems are not well understood. This study analyzes agricultural change associated with subsistence-based indigenous production systems in the lower Pastaza River Basin in the Ecuadorian Amazon through a spatially explicit dynamic model. The model integrates multiple logistic regression and cellular automata to simulate agricultural expansion at a resolution consistent with small scale agriculture and deal with inherently spatial processes. Data on land use and cultivation practices were collected through remote sensing and field visits, and processed within a geographic information system framework. Results show that the probability of an area of becoming agriculture increases with population pressure, in the vicinity of existing cultivation plots, and proximity to the center of human settlements. The positive association between proximity to cultivation areas and the probability of the presence of agriculture clearly shows the spillover effect and spatial inertia carried by shifting cultivation practices. The model depicts an ideal shifting cultivation system, with a complete cropping-fallow-cropping cycle that shows how agricultural areas expand and contract across space and over time. The model produced relatively accurate spatial outputs, as shown by the results of a spatial comparison between the simulated landscapes and the actual one. The study helped understand local landscape dynamics associated with shifting cultivation systems and their implications for land management.

Comprehensible Technique in Solving Consecutive Number Problems in Algebra  [PDF]
Gener Santiago Subia
Journal of Applied Mathematics and Physics (JAMP) , 2018, DOI: 10.4236/jamp.2018.63041
Abstract: This research paper evaluated and investigated the effectiveness of the comprehensible technique (CT) introduced by the researcher as an alternative solution to Algebra’s linear equations in solving consecutive number problems. The CT is a proposed easy and efficient way of solving number problems which aimed to help the learners reduce their difficulties in using variables since the technique only uses basic arithmetic and mental Mathematics. Evaluation research was utilized in this study where 20 people, from various ages and professions, were chosen purposively as respondents of the study. The study found out that CT was very effective for the respondents especially in unlocking difficulties in solving consecutive number problems. Moreover, according to them, the CT is easy to use, it is engaging and enjoyable, direct and simple and can be utilized as shortcut way of solving consecutive number problems when competing in Math quiz bees or taking board examinations where time is of the essence.

Trials , 2011, DOI: 10.1186/1745-6215-12-191
Abstract: The aim of the present randomised, double-blind, placebo-controlled clinical trial was to assess the efficacy and tolerability of latex sublingual immunotherapy in adult patients undergoing permanent latex avoidance.Twenty-eight adult latex-allergic patients (5 males and 23 females), with mean age of 39 years (range 24-57) were randomized to receive a commercial latex-sublingual immunotherapy or placebo during one year, followed by another year of open, active therapy. The following outcomes were measured at baseline and at the end of first and second year of follow-up: skin prick test, gloves-use score, conjunctival challenge test, total and specific IgE, basophil activation test, and adverse reactions monitoring.No significant difference in any of the efficacy in vivo variables was observed between active and placebo groups at the end of the placebo-controlled phase, nor when each group was compared with their baseline values at the end of the two year-study. An improvement in the average percentage of basophils activated was observed. During the induction phase, 4 reactions in the active group and 5 in the placebo group were recorded. During the maintenance phase, two patients dropped out due to pruritus and to acute dermatitis respectively.Further studies are needed to evaluate latex-sublingual immunotherapy, since efficacy could not be demonstrated in adult patients with avoidance of the allergen.ACTRN12611000543987Natural rubber latex (NRL) is an ubiquitous material and NRL-allergy is a relatively recently considered diagnosis as it was first recognised in the late 70s [1,2]. It mostly affects certain groups of high risk populations (health care workers, patients with frequent hospitalization) but the prevalence of latex sensitisation in general population is also far from negligible. Moreover, there has been a recent increasing number of cases of NRL-allergy in other occupations including hairdressers, housekeepers, construction workers, food handlers or secu
Is the Space-Time a Superconductor?  [PDF]

At the fundamental level, the 4-dimensional space-time of our direct experience might not be a continuum and discrete quantum entities might “collectively” rule its dynamics. Henceforth, it seems natural to think that in the “low-energy” regime some of its distinctive quantum attributes could, in principle, manifest themselves even at macroscopically large scales. Indeed, when confronted with Nature, classical gravitational dynamics of spinning astrophysical bodies is known to lead to paradoxes: to untangle them, dark matter or modifications to the classical law of gravity are openly considered. In this article, the hypothesis of a fluctuating space-time acquiring “at large distances” the properties of a Bose-Einstein condensate is pushed forward: firstly, it is shown that a natural outcome of this picture is the production of monopoles, dyons, and vortex lines of “quantized” gravitomagnetic—or gyrogravitational—flux along the transition phase; the minimal supported “charge” (and multiples of it) being directly linked with a nonzero (minimal) vacuum energy. Thus, a world of vibrating, spinning, interacting strings whose only elements in their construction are our topological concepts of space and time is envisioned, and they are proposed as tracers of the superfluid features of the space-time: the archetypal embodiment of these physical processes being set by the “gravitational roton”, an analogue of Landau’s classic higher-energy excitation used to explain the superfluid properties of helium II. The far and the near field asymptotics of string line solutions are presented and used to deduce their pair-interaction energy. Remarkably, it is found that two stationary, axis-aligned, quantum space-time vortices with the same sense of spin not only exhibit zones of repulsion but also of attraction, depending on their relative geodetic distance.

Enzyme Kinetic Equations of Irreversible and Reversible Reactions in Metabolism  [PDF]
Santiago Imperial, Josep J. Centelles
Journal of Biosciences and Medicines (JBM) , 2014, DOI: 10.4236/jbm.2014.24005

This paper compares the irreversible and reversible rate equations from several uni-uni kinetic mechanisms (Michaelis-Menten, Hill and Adair equations) and bi-bi mechanisms (single- and double- displacement equations). In reversible reactions, Haldane relationship is considered to be identical for all mechanisms considered and reversible equations can be also obtained from this rela- tionship. Some reversible reactions of the metabolism are also presented, with their equilibrium constant.

Hermeneutical Theodolite of Requirements: Evaluating and Revealing the Quality Grades of Software Requirements and of Domain of Application  [PDF]
Wagner Varalda, ítalo Santiago Vega
Journal of Computer and Communications (JCC) , 2018, DOI: 10.4236/jcc.2018.65004
Abstract: Throughout the development of software, during Requirements Engineering activities, software requirements dynamically and constantly evolve and mature from an “identified” stage to an “approved” stage. This evolution takes place individually for each requirement, in a very particular way, because it depends on the level of understanding that the requirements engineer reaches in relation to it. How, then, to monitor the evolution of each software requirement? How to know the quality of each software requirement? How to measure the level of understanding and difficulty that the requirements engineer has in relation to each software requirement? This paper aims to present a proposal to answer these questions through the use of an instrument developed specifically to assess and reveal the quality grades of each software requirement and also to assess and reveal that the levels of understanding and of difficulty of the requirements engineer is in relation to each software requirement. This instrument was called the Hermeneutical Theodolite of Requirements, which also can be applied to evaluate that the levels of understanding and of difficulty of the requirements engineer is in relation to the domain of application, essential input artifact and primordial to the specification of the requirements of software.
Hermeneutical Elicitation of Requirements: A Technical Perspective to Improve the Conception of the Software Requirements  [PDF]
Wagner Varalda, ítalo Santiago Vega
Journal of Computer and Communications (JCC) , 2018, DOI: 10.4236/jcc.2018.69010
Abstract: In order to develop quality software that meets the originals needs of its users, it is necessary to perform the Requirements Engineering, so that the software context to be developed is identified, examined and specified properly. However, there is a problem that is increasingly in debate: the difficulty in understanding and establishing the purpose of the software to be developed, as pointed out by important researches in the area, such as the Chaos Report, which indicates that only 29% of software projects are successful, and the Software Engineering Institute, which points out software requirements as a critical factor for the success of software engineering and that deficiencies in this dimension are the main causes of software project failures. This article presents a proposal to address this problem through the use of the Hermeneutical Elicitation of Requirements, which is the conceptual adequacy of some hermeneutical methods in a technical approach that assists the requirements engineer to conceive better of the software requirements. In this way, the software engineer will be better able to develop the software to better meet the needs of its end users and sponsors.
