The present of this study was to identify the relationship between psychosocial factors and the organizational climate present in the workers of a dermocosmetic laboratory. A cross-sectional, descriptive and propositive, non-experimental research design was used, according to the methodological categories suggested by (Hernández, Fernández and Baptista, 2010), applying the battery of psychosocial risk, proposed by the Ministry of Labour (2011); further, we conducted focus groups, knowing the worker’s perception of variables that evaluate the organizational climate. The quantitative results show that Demands of Responsibility of the Office with 78%, Characteristics of Leadership and Social Relations at Work with 65% and Feedback and Performance 58%, are found at high and very high risk levels; results that coincide with the qualitative data evidenced by workers in the focus groups. There is then a direct relationship between psychosocial risks and the variables of the organizational climate, because as the former are present, they generate conditions that alter the organizational climate. For this reason, an intervention proposal is designed that allows the improvement of working conditions, strengthening the safety, health and well-being of workers.

El petróleo es motor de progreso, desarrollo y riqueza y ha exigido de los científicos, profesionales y directores de seguridad un estudio sistemático de los incontables riesgos profesionales que su manejo genera para desarrollar meticulosos procedimientos y tecnologías dirigidas a evitar los accidentes de trabajo, las lesiones y los incendios.

El tema de la Gestión de Tránsito tiene una relevancia mayor que la que el público poco conocedor puede suponer. A la pregunta de muchas personas: ¿cuándo se solucionarán definitivamente los problemas de tránsito y de congestión?, la respuesta es: no hay solución definitiva. El tránsito se gestiona. La Ingeniería de Transporte hispanoamericana encontrará en este libro una importante guía para el manejo de distintos tipos de problemas asociados.

Esta investigación pretendió construir un modelo automatizable de documentación de procesos. Se espera que este permita dar respuesta a los requisitos de varios sistemas de gestión, de manera que una organización pueda estandarizarlos y automatizarlos con la confianza de cumplir, al mismo tiempo, con lo establecido tanto por el Consejo Nacional de Acreditación (cna), como por la norma iso 9001 y la Business Process Management (bpm). Se analizaron de manera minuciosa y comparativa estos modelos. Los resultados se utilizaron para complementar el contenido del manual. El modelo resultante se aplicó directamente en el contexto organizacional. Los resultados muestran que es posible documentar procesos al detalle, cumplir con estándares internacionales, responder con rapidez a cambios con base en las mejoras que los procesos pueden presentar y llevar el contenido del modelo propuesto a una Business Process Management Suite (bpms), ahorrando con esto costos, tiempo y otros elementos valiosos.

The excavation for the 53-story reinforced concrete One Museum Park West building (OMPW) in Chicago was constructed using combined support systems. The building was supported by caissons and a perimeter wall formed by secant piles which transitioned to tangent piles below the bottom of the cut. After installing the perimeter wall and deep foundations for the building, the excavation for the reinforced concrete central core was supported by a circular cofferdam made of sheet piles and steel ring beams. This excavation was made using conventional bottom-up excavation techniques. The excavation for the rest of the building was made using a top-down method and was laterally braced with reinforced concrete floor slabs structurally connected to the secant pile walls and the reinforced concrete core. Field performance data during construction of the OMPW basements were collected with settlement points, inclinometers and strain gages installed in the concrete basement slabs. Significant settlements were observed adjacent to the excavation during wall and deep foundation installation, central core construction and top-down excavation. The influence of concrete material time-dependence of the floor slabs on the performance during top-down excavation is evaluated and a method for the separation of temperature-related strains from the excavation-induced strains in the concrete is described. The construction of the basements is simulated with a 3D numerical structural model to study the influence of the concrete material time-dependence of the floor slabs in the excavation-induced movements resulting from top-down construction. Computed strains in the floor slabs are compared with the observed performance data collected from the strain gages. For use in numerical simulation of the entire excavation process, hypoplasticity constitutive parameters for clays (HC model) at the element test level were calibrated with tests conducted on high quality block samples obtained from the excavation of Block 37 project in Chicago. They included oedometer tests, bender element measurements, and triaxial tests following different stress probes, and were further refined with seismic cone penetration results.  The entire OMPW excavation is simulated with the calibrated parameters with a fully coupled-flow deformation, three-dimensional finite element model. Influence of the construction of secant pile walls, concrete material time-dependence, and nonlinear concrete behavior of the perimeter pile walls on the performance of the OMPW excavation is determined. Conclusions about top-down construction are drawn in light of the measured and simulated performance of the OMPW excavation.

The OpenModelica Compiler-Compiler parser generator (OMCCp) is an LALR(1) parser generator implemented in the MetaModelica language with parsing tables generated by the tools Flex and GNU Bison. The code generated for the parser is in MetaModelica 2.0 language which is the OpenModelica compiler implementation language and is an extension of the Modelica 3.2 language. OMCCp uses as input an LALR(1) grammar that specifies the Modelica language. The generated Parser can be used inside the OpenModelica Compiler (OMC) as a replacement for the current parser generated by the tool ANTLR from an LL(k) Modelica grammar. This report explains the design and implementation of this novel Lexer and Parser Generator called OMCCp. Modelica and its extension MetaModelica are both languages used in the OpenModelica environment. Modelica is an Object-Oriented EquationBased language for Modeling and Simulation.

This thesis proposes a novel window aggregate sharing approach for out-of-order stream processing. We combined together the best of two worlds: the Google dataflow model for out-of-order stream processing and the Cutty aggregate sharing strategy. To our knowledge, our solution is the only aggregate sharing strategy for out-of-order stream processing that supports sliding, tumbling and session windows. Based on the experiments with the real world dataset DEBS12 [28] and a 3% out-of-order level, our solution has 1.24 higher throughput than the current implementation in Flink. Moreover, we show that the throughput of our solution becomes higher, as the out-of-order level increases.

A simple apparatus was designed to collect ammonia gas coming out from waste stabilization ponds (WSP). The apparatus has a capture chamber and an absorption system, which were optimized under laboratory conditions prior to being used to assess ammonia volatilization rates in a pilot-scale maturation pond during summer 2005. Under laboratory conditions (water temperature ¼ 17.1 8C and pH ¼ 10.1), the average ammonia volatilization rate was 2,517 g NH3-N/ha d and the apparatus absorbed 79% of volatilized ammonia. On site, the mean ammonia volatilization rate was 15 g N/ha d, which corresponds to 3% of the total nitrogen removed (531 g N/ha d) in the maturation pond studied. A net nitrogen mass balance showed that ammonia volatilization was not the most important mechanism involved in either total nitrogen or ammonia removal. Nitrogen fractions (suspended organic nitrogen, soluble organic nitrogen, ammonia, nitrite and nitrate) from the M1 influent and effluent showed that ammonia is removed by biological (mainly algal) uptake and total nitrogen removal by sedimentation of dead algal biomass.
