Design framework:redesign and new multi-user and testing support

The use of models to conceptualize systems is an important part of the process of building Cyber Physical Systems. While designing such systems, which are in general a multi-disciplinary activity, multiple designers are involved in the design decisions. Those decisions most likely are not captured and eventually forgotten after a period. The Design Framework is a visual modeling tool that aims to help architects and designers to documents the design rationales besides the design artifacts. It also helps them to collaborate to design a system together in a multidisciplinary environment. The Design Framework is at the level of a good prototype, but it is not ready for operational application by end-users in industry. One of the main issues with the Design Framework system is a sub-optimal code structure due to the lack of proper design and development approach. The assignment therefore is to reverse engineer the current design of the Design Framework and to come up with a new design. In order to maintain a system in use, presence of a test framework is necessary. Since the Design Framework is used in a multi-disciplinary environment, an improvement in the multi-user support of the system is also needed. In the first part of this report, the redesign of the Design Framework is discussed. To redesign the Design Frame-work, a number of refactoring techniques are applied. As a result, the code complexity is reduced, therefore the maintenance is increased. The second part of the assignment includes multi-user support and testability. The Design Framework manages the changes to design descriptions and maintains the history of the design artifacts. In this respect, it operates similar to version control systems. In the multi-user part of this report, the version controlling aspect of the Design Framework is described and synchronization of data for multi-user is elaborated. Finally some multi-user features are improved and developed. In the testability part of this report, the test support is described. A set of unit tests and end-to-end tests including the test for multi-user support is implemented. Provided test sets and the approaches used to setup test environment makes the Design Framework more stable and maintainable

Studying young people’ views on deployment of renewable energy sources in Iran through the lenses of Social Cognitive Theory

Renewable energy sources (RES) have potentials to address goals of climate change mitigation at the global level. Iran has abundant RES potentials and investment into renewable energy sources can contribute to its socio-economic development and to diversification of its energy mix. Economic and technical capacities but also human factors, such as stakeholders’ views, public and social acceptance, as well as willingness to use RES, willingness to pay for their deployment and to participate in decision-making processes on energy transition, are crucial factors for deployment of RES at scale. These human factors impact development and implementation of energy transition at the national and local governance levels. Deployment of new technology and energy transition can lead to conflicting views, believes and risks perceptions among involved stakeholders but also among people affected by deployment of new technology infrastructure deployment. To be sustainable and acceptable by all social groups, such process should be based on understanding of positions of different stakeholders and development of compromise solutions. It is crucial to understand the views of young people on deployment of RES as young people represent a significant share of population and are future decision makers. Their support and willingness to use RES will be a significant driver for RES deployment in short and medium term. Based on socio cognitive theory this paper examines the patters of behavior of young adults in relation to energy use. The results show positive influence of self-rewarding to encourage young adults to participate in energy transition. Another important driver is expectation of social outcome, which involves existing social norms in the community. Trust to the source of information is another important driver and the level of information about RES has an important influence on the willingness to use them

Saliva Secretion and Efficacy of Helicobacter Pylori Eradication in Peptic Ulcer Patients

Objective: It has been noted that the presence of Helicobacter pylori (H. pylori)in the oral cavity may affect the outcome of eradication therapy. This condition is associated with the recurrence of gastric infection. The optimum secretion of salivapromotes oral health consequently influencing H. pylori eradication. The purpose of this study was to investigate the relation between salivary secretion and the efficacy of H. pylori eradication from the stomach.Materials and Methods: Forty five patients with gastric H. pylori infection were enrolled in this study. Diagnosis of H. pylori infection was confirmed by endoscopy,biopsy, urease test and histological examination. Salivary secretion of all participants was determined under standard condition before the beginning of antibacterial treatment. Then the patients were treated with a 14-day course anti-H. pylori regimen consisting of amoxicillin, omeprazole, metronidazole and bismuth. The efficacy of eradication therapy was evaluated 4 weeks after the end of the treatment course. Mann-Whitney U test was used to analyze the variables.Results: The median of salivary secretion among successful and unsuccessful H. pylori eradication groups was 0.48 ml/min and 0.24 ml/min, respectively (p=0.005).Conclusion: Although the type of drug regimens is challenging, the efficacy of H. pylori eradication from the stomach might be reduced by lower salivary secretion

Identification of chemical compounds of <em>Nardostachys Jatamansi </em>essence available in Iran

Introduction: With regard to using drugs with plant origin and with the aim of suitable use of these types of drugs and preventing them to be abused, it is necessary to determine the standards of these plants. The aim of the present study was to identify and study chemical compounds of Nardostachys Jatamansi essence in Iran and define monograph of this plant for the Iranian plant pharmacopeia. Methods: In an experimental study the Nardostachys Jatamansi specimen was prepared from the market in Iran. The essence of the plant was prepared by the hydro-distillation in Clevenger apparatus. Essence was obtained as a greenish yellow oil layer with the 0.07 yield. The essence compounds were identified quantitatively by Gas Chromatography-Mass Spectroscopy (GC/MS) method. Results: Totally, 29 compounds were identified in Nardostachys Jatamansi essence. The retention indexes (RI) were only similar with overall standard values in two compounds like mesitylene and P-cymene. In this line the RI values about three compounds of valerenic acid, palmitic acid, and valerenyl isovalerate were determined significantly higher than standard values of RI. Conclusion: The essence prepared from the Nardostachys Jatamansi plant in Iran was different in terms of some compounds and components including valerenic acid, palmitic acid, and valerenyl isovalerate and so it is necessary to identify and register quality and quantity characteristics of compounds available in this plat in the Iranian medicinal plants pharmacopeia.</p

Prácticas reflexivas del saber cultural Guaraní, en espacio de enseñanza - aprendizaje, fuera del contexto paraguayo

Anais do I Encontro de Iniciação Científica e de Extensão da Unila - Sessão de Artes e Linguística - 05/06/12 - 14h00 às 18h00 - Unila-Centro - Sala 16 - 3o PisoHemos empezado esa investigación con muchas preguntas para las que buscamos respuesta ¿Qué guaraní enseñar? ¿Qué contenido de gramática aplicar? ¿Qué interés tendrán los alumnos? Cómo se daría en pro - ceso de enseñanza y aprendizaje en el contexto extranjero. Esas interrogantes surgen a partir de decisio - nes como la enseñanza del guaraní, que por su naturaleza denota particularidades diferentes a otras len - guas y por lo tanto nos exigió nuevos planteamiento cuanto a su enseñanza y aprendizaje. La Lengua Guarani incorporada en diversos ámbitos de la universidade ha generado un matiz muy particular de co - nocimiento, saberes y curiosidades. Más allá del aprendizaje del idioma, se involucran otros saberes y ras - gos culturales guaraníes, no solo se ensenã y se aprende el idioma, sino también las experiencias del vivir y ser guaraní: las músicas, las danzas, la gastronomía, las leyendas como un todo del entorno de uso de la lengua. En análisis de las prácticas en clase de guaraní - fuera de un contexto paraguayo - ha explicitado el interés de los extranjeros en esos elementos de nuestra cultura. Reflexionar sobre cada acción: enseñan - za, aprendizaje, adquisición, objetivos del curso y prácticas de alumnos, professores y colaboradores pue - de aportar nuevos rumbos a la enseñanza y aprendizaje de lenguas en contextos de integración y de inter - culturalidad. Para llevar a cabo nuestro propósito de observar, analizar y traer los resultados a la práctica en el salón de clase, hemos tratado de hacer el registro de todas las actividades realizadas. Eso nos facilitó el trabajo de análisis de todo el proceso de enseñanza y aprendizaje, incluso, nuestras actitudes como do - centes por medio de una investigación acción colaborativa. Nuestra actuación como professores de nues - tra lengua materna - el guaraní - pudo aportar tanto conocimientos nuevos sobre la enseñanza de lengua como un reconocimiento y valoración de ese idioma no solo en Unila, sino en Foz do Iguaçu, Brasily en Paraguay. El análisis de nuestras actitudes como profesores y de los alumnos nos llevó muchas veces a re - plantear las clases y nuestra forma de pensar y actuar el proceso de enseñanza y aprendizaje de lenguas. A diferencia de lo que ocurre con idiomas próximos, la enseñanza del guaraní para hablantes de português y de español explicita la necesidad de repensar nuevas formas de transmisión de los saberes linguístico-cul - turales en nuestra universidad y en nuestros países. La metodología empleada en cuanto a las anotaciones del proceso realizado como reflexión del desarrollo de las clases, para una experiencia y mejora de lo rea - lizado. Se propicia, dinamismo, interés y el mismo aprendizaje a lo que se agrega el trabajo por práctica escrita y oral. En consecuencia, se logra crear un espacio favorable en la difusión del idioma, la cultura, saberes populares, etc. Su trasmisión forja el aprendizaje, el guaraní ha llegado a transformar pensamien - tos y actitudes, tabúes y desconocimientos. Valoramos la herencia de los guaraníes, valoramos y respeta - mos.Universidade Federal da Integração Latino-Americana (UNILA

Association of human platelet alloantigens encoding gene polymorphisms with the risk of Coronary artery disease in Iranian patients

Background: Coronary artery disease (CAD) is characterized by narrowing/ blockade of coronary arteries that is mainly caused by atherosclerotic plaques. Considering the involvement of platelet abnormalities, such as defective aggregation and adhesion, in the cardiovascular-related disorders, genetic variations in human platelet alloantigens (HPA) have been implicated in the CAD susceptibility. Herein, we intended to determine the association of HPA-1 to -6, -9, and -15 biallelic polymorphisms with CAD in an Iranian population. Methods: In this retrospective case�control study, 200 CAD subjects and 100 matched healthy individuals were enrolled. DNA samples were isolated from peripheral blood samples and genotyping of HPA polymorphisms was accomplished using polymerase chain reaction-sequence-specific primers. Results: The alleles and genotypes of studied HPA polymorphisms were equally distributed among cases and controls and therefore no statistically significant differences were detected. Univariate analysis identified no association of combined haplotypes with CAD risk. However, multivariate analysis showed a positive association of the� HPA1b/2a/3b haplotype with CAD after adjustment for some covariates (including BMI, TG, LDL, FBS and blood pressure) that conferred a CAD susceptibility haplotype (P = 0.015; OR = 2.792; 95 CI 1.45�8.59). Conclusions: Although alleles, genotypes, and haplotypes of HPA polymorphisms were not associated with CAD risk, HPA1b/2a/3b haplotype was found to be a dependent disease risk haplotype in Iranian population after correcting for confounding factors. © 2021, The Author(s)
