Zika virus spreads to people primarily through the bite of an infected Aedes aegypti species mosquito. But it Zika can also be passed through sex from an infected to his or her sex partners and it can be spread from a pregnant woman to her fetus. Zika continues to spreading geographically to areas where competent vectors are present. Although a decline in cases of Zika virus infection has been reported in some countries, or in some parts of countries, vigilance needs to remain high. In this work, we propose a mathematical model that uses diffusion-advection equations to study the impact of the Zika epidemic. We present a numerical scheme linking finite elements (FEM) with finite differences to solve the model. The computer simulations are performed for Paramaribo and Santa Ana that have different demographic characteristics and allow us to extend the study to other regions.

The cytochrome P450 14alpha-sterol demethylase is an enzyme of the Mycobacterium tuberculosis (MT) that by redundancy of its gene that codifies it in the genome of MT should have preponderant rolls for the survival of the pathogen. Using the published models of the structure 3D of this enzyme, we evaluated by «docking» computational method interaction of this protein to ligands of azole type, those that were modeled by geometric optimization and present values of LogP up to 4,9, which indicates their extreme lipophilicity, being observed with clotrimazole the best values for its docking with the protein.

Las instituciones de educación superior tradicionalmente miden el éxito de los estudiantes y la calidad de un programa académico mediante métricas estándar, como el tiempo que tarda un estudiante en obtener un título, las tasas de graduación y las tasas de retención. Además, algunos programas han instituido un "examen de calificación" como una forma alternativa de medir la calidad de un programa académico y evaluar el dominio del estudiante en los conceptos básicos. El programa de Ciencias de la Computación (CS) de la Universidad de Florida Central implementó un examen de calificación "Examen básico" en 1998 con el propósito de evaluar el dominio de los estudiantes de los conceptos básicos de CS y controlar la calidad del programa. Sin embargo, las tasas de aprobación de los estudiantes que tomaron este examen de calificación fueron significativamente bajas a lo largo...

This research is part of an exploratory study that focuses on the observation and analysis of the integration of the tablet in the classroom, and it takes part of the «EduTablettes-86» project (Poitiers, France). This study addresses the «pervasive computing» or «ubiquitous computing» as an approach that allows us to understand the direction of technology and its relation to the use of the tablet in the school, in addition, the theory of «situated action» is used as a reference and it makes possible to study the tablet in an application context, besides that, it includes the notion of communication «Human-Machine» to understand and to reflect on the interaction: teacher-student-tablet. We made use of the «ethnomethodology» as a method to understand the organization and structuring of a class session.

Objective. Determine the relationship of bone quality in cortical bone according to the different regions of the maxilla and mandible by histomorphometry and the equivalent Hounsfield values of Cone Beam computed tomography in partially edentulous patients. Methods.

Abstract: To compare the diagnostic accuracy of digital radiography (DR) and cone beam computed tomography (CBCT) in the detection of peri-implant bone defects. Materials and methods: Implants were placed in 5 fresh bovine ribs (3 without peri-implant bone defects, 12 with 1.4mm peri-implant bone defects) and images were taken using (i) portable x-ray system (DEXCOWIN 3000), (ii) intraoral x-ray sensor (SENSOR H1/SENSOR H2), (iii) volume-limited HSCT with 3D Accuitomo 80 (CASTELLINI). Images of each were randomly presented to 10 examiners. Confidence in the diagnosis of the presence or absence of a peri-implant radiolucency was recorded on a scale of bone defect definitely absent, doubts about the defect if absent or present, defect definitely present. Analyzes was performed using a kappa test. Results: There has been a coincidence between the direct digital radiography and the cone beam...

Objectives: determine the total length and the largest diameter in cervical, middle and apical level of deciduous mandibular first molars using cone beam computed tomography. Materials and method: In this cross-sectional study a sample of 21 deciduous upper first molars with the length of the complete root and no fracture was analyzed. The teeth were scanned using CT Cone Beam, the diameter of the root canal was measured by taking three points of reference for these measures, cervical, middle and apical. The obtained images were examined and measured by mean a 3D processing imagery software. The measures of the ducts was made by a single observer (CCI= 0.70); nonparametric Kruskal-Wallis test to compare and find the differences were used. Results: The average length of deciduous upper first molars was 13.53 mm, 5.61 mm crown and root 7.92 mm. The average diameter of the palatal root cana...

Las formulaciones de elementos finitos Mixto se utilizan para aproximar las variables de presión y desplazamiento simultáneamente para problemas de Poisson. El proposito de este articulo es analizar una nueva aproximación mixta discreta basada en la aplicación de la version enriquecida de Poisson clásico - espacios compatibles. Con ese propósito decidimos medir el costo computacional de aplicar tres formulaciones para dos problemas de Poisson con solución exacta conocida. El objetivo no es comparar que formulación es mejor, sino mas bien para resaltar las características del costo computacional y los errores obtenidos tanto para variables primal y dual. Las formulaciones debiles correspondientes a la aplicacion del H1− conforme clasico, el metodo mixto y el método mixto enriquecido en los algoritmos desarrollados, calculan el error de la variable primal y medimos el costo com...

Recent investigations emphasize the importance of cybersecurity in the growing digital era; 83% of organizations experienced breaks in cyber security in 2022, spending a mean of 4,35 million dollars per incident. Cybersecurity in Peru is regulated by legal norms aimed at protecting data and providing informatic security. Objective: To describe cybersecurity in the support services to occupational physicians (SSOP) in the city of Lima. Methods: A non-validated survey was created and distributed to 11 SSOPs in Lima that provide a service to an important building project in Lima. Results: More than 80% of health care establishments had a response plan against cybernetic attacks; security copies of the data were done regularly storing them in a different place than the establishment and regularly updated security software’s. Conclusion: The cybersecurity program is reactive. We discuss the...

Molecular Docking (MD) es una herramienta clave en el diseño de medicamentos asistido por computadora. AutoDock es un código MD ampliamente utilizado que ejecuta un algoritmo genético lamarckiano (LGA) y, el método Solis-Wets como algoritmo de búsqueda local. Este tesis presenta una paralelización de AutoDock basasa en OpenCL, y su evaluación correspondientes en términos de rendimiento de ejecución, calidad de resultados y eficiencia de cálculo de energía, lograda en CPUs, GPUs y FPGAs. Si bien un enfoqu de paralelización basada en datos ha demostrado su efectividad en CPUs y GPUs, se observó que para FPGAs, dicho enfoque resultó en ejecuciones más lentas. Para superar este inconveniente, también se analiza una paralelización basada en tareas para FPGAs. Además, esta tesis amplía la búsqueda de LGA con nuevos métodos alternativos de búsqueda local basados en gradien...

We study a system formed by M dimers through half-filled two-site Hubbard model, with two electrons. Our approach use the third version of Nonextensive Statistical Mechanics as tool for calculating thermodynamic and magnetic parameters such as entropy, internal energy, magnetization and specific heat. In the computer simulations, we vary the q entropic index values between 1 and 2, such that, q = 1.0, 1.4, 1.7 and 2.0. These values are interesting to study small magnetic systems. We find the critical temperature regions in simulations with the simple Hubbard model, i.e. without the intersite interaction. For other side, adding this additional term, we notice an enlargement and shifting of the thermodynamic parameters comparing with the obtained from simple Hubbard model; even more, we found in some cases the absence of the critical temperature regions.
