Este proyecto de grado se basa en el estudio de una empresa comercializadora de repuestos para la industria lechera colombiana, con el fin de desarrollar una herramienta de gestión que le permita evaluar y controlar los niveles de inventario. El inicio del proyecto consistió en el estudio de los comportamientos de demanda de los repuestos más relevantes seleccionados a través de una clasificación ABC. Debido a los característicos comportamientos de un sistema de inventarios de repuestos, se estudiaron y realizaron pronósticos a través del método de Syntetos and Boyland, y el método de Croston. Se efectuó un cuidadoso desglose de costos necesario para el establecimiento de un sistema de revisión propicio y completamente coherente con la realidad. Finalmente, se establecieron inventarios metas e inventarios de seguridad con el fin de dejar completamente definido el sistema. Complementario al proyecto se estableció de manera descriptiva una sugerencia que permitiera realizar un almacenamiento de los repuestos de manera más ordenada y ágil.

La evaluación del suministro de carnes rojas para grandes felinos representa en el zoológico de Cali una problemática a estudiar. Actualmente los grandes felinos del zoológico son alimentados con animales donados (enfermos o recién fallecidos), después de recibir la donación, se realizan una serie de exámenes para determinar si la carne cumple con los requisitos para alimentar a los leones. De acuerdo al nivel de inventario de carne, se determina si se puede mantener al animal donado con vida, o si debe ser faenado inmediatamente para ser suministrado; en el caso que este ya esté muerto, se determina la causa por medio de exámenes y se establece si debe ser administrado inmediatamente, almacenado o rechazado. Para realizar el proceso anterior, las instalaciones del zoológico cuentan con un matadero sin la infraestructura adecuada y con incinerador para eliminar los residuos de los animales donados, materias fecales y basuras en general. El zoológico de Cali no cuenta con certificados de calidad bajo la normatividad gubernamental, en la alimentación entorno a los grandes felinos, para esto, el zoológico necesitaría eliminar el matadero y el incinerador, tendría que comprar todo su suministro de carnes y tercerizar los desechos. En cuanto a la planeación, el zoológico recoge las donaciones en diferentes municipios del Valle del Cauca y realiza viajes así sea para recoger un solo animal. Esta actividad genera unos costos que no se han estimado.

El porvenir social y económico de una ciudad depende, en gran medida, de la eficiencia de su sistema de transporte; esto se ve reflejado en la capacidad de transportar personas y bienes de una forma sostenible, con los recursos disponibles. En la actualidad se encuentran en desarrollo sistemas de transporte masivo tipo Bus Rapid Transit [BRT] en siete ciudades colombianas, situación que genera la necesidad de dar seguimiento a su progreso y al crecimiento de su participación en la demanda de viajes unipersonales. El siguiente trabajo busca, a través de una simulación en dinámica de sistemas, describir el desarrollo de un sistema de transporte masivo, con el fin de otorgar una visión acerca del impacto de los parámetros operativos y la reinversión en el sistema y en el desarrollo e incremento de su demanda. Se plantean tres escenarios para evaluar diferentes políticas operativas y de reinversión en el sistema, analizando el comportamiento en su desarrollo.

El presente documento tiene como propósito establecer en qué medida la concentración y el tamaño de la banca comercial puede afectar, si es que se da, la exposición de riesgo en el sistema bancario colombiano en el periodo de 1995 – 2014 -- Para tal fin, se siguió la metodología de Chumacero y Langon (2001) y Barro (2011), la cual realiza un modelo de serie de tiempo, tomando la razón entre cartera total y cartera vencida del total de los bancos, como variable proxy que mide el riesgo; así mismo, el indicador Herfindahl - Hirschman que determina el nivel de concentración, finalmente, con la razón entre activos de la banca como porcentaje del PIB -- El resultado obtenido describe que para el caso de la concentración, muestra un coeficiente menor a cero, que soportaría la idea de que la competencia se daría en riesgo ofertado en el mercado bancario colombiano; el tamaño por su parte, su coeficiente registra ser mayor que cero, soportando la existencia de bancos demasiado grandes para quebrar

Multi-element analyses of sediment samples from the Santos-Cubatão Estuarine System were carried out to investigate the spatial and seasonal variability of trace-element concentrations. The study area contains a rich mangrove ecosystem that is a habitat for tens of thousands of resident and migratory birds, some of them endangered globally. Enrichments of metals in fine-grained surface sediments are, in decreasing order, Hg, Mn, La, Ca, Sr, Cd, Zn, Pb, Ba, Cu, Cr, Fe, Nb, Y, Ni and Ga, relative to pre-industrial background levels. The maximum enrichment ranged from 49 (Hg) to 3.1 (Ga). Mercury concentrations were greater in the Cubatão river than in other sites, while the other elements showed greater concentrations in the Morrão river. Concentrations of Mn were significantly greater in winter and autumn than in summer and spring. However, other elements (e.g. Cd and Pb) showed the opposite, with greater concentrations in summer and spring. This study suggests that seasonal changes in physical and chemical conditions may affect the degree of sediment enrichment and therefore make the assessment of contamination difficult. Consequently, these processes need to be considered when assessing water quality and the potential contamination of biota.

A solid-phase in-line extraction system for water samples containing low levels of emerging contaminants is described. The system was specially developed for large volume samples (up to 4 L) using commercial solid-phase extraction (SPE) cartridges. Four sets containing PTFE-made connectors, brass adapters and ball valves were used to fit SPE cartridges and sample bottles to a 4-port manifold attached to a 20 L carboy. A lab-made vacuum device was connected to the manifold cap. The apparatus is robust and less expensive than the typical available system. Its also provides less experimental handling, avoiding cross contamination and sample losses.

The difficulty in adapting European dairy cows breeds in Brazil affect considerably the milk production sector. Brazilian climatic conditions are not totally favorable and the development of new tecnologies is needed for the animals express their genetic potential, as well as their best feed conversion. An economical analysis of the applied investment in the free-stall climatization equipment in dairy housing, for estimating studies related to profit, possibility of return investment as well as time for this return is necessary. The objective of this research was to evaluate the influence of climatization investment in the milk production process and analyze the economical aspect of this investment. There were used 470 high productive dairy cows with genetic and morphologic homogeneous characteristics, and analyzed in two similar periods. Investment calculations were done using Excell®. The results were satisfactory and the invested capital was proved to return to the producer in a short term, 57 days.

In the last few years the sugar-cane mechanical harvested area has increased, especially in regions with appropriated slop. The use of this technology brings some inconveniences, such as, the increase in the percentage of extraneous matter, which causes the reduction of technological quality of the raw material, and losses in the field. Extraneous matter (trash) is composed of tops and leaves in major percentage, plus soil and roots, and eventually some metal parts. In the green cane harvest system the percentage of extraneous matter has a tendency to increase due to the great amount of vegetal matter to be processed. The increase in the blower fan speed to reduce the amount of extraneous matter can lead to an unacceptable economic level of raw material losses. The main objective of this work was, using a cane loss monitor, to evaluate and quantify the amount of visible losses of sugar cane through the primary extractor at two different fan speeds. Afterwards these losses were related to the harvester cleaning efficiency. The piezoelectric transducer shows a reasonable sensibility. The results show that the cleaning efficiency in the primary extractor (85% mean), the cane losses (between 5.68% and 2.15%) and fan speed are interrelated. The total losses and specially splinters (between 3.19% and 0.91%), showed a significant difference among the treatments.

One of the problems found in mechanical harvest of sugar cane is the lack of synchronism between the harvest machine and the infield wagon, causing crop losses as well as operational capacity. The objective of the present research was to design a system capable of helping to synchronize the sugar cane harvest machine with the wagon. The communication between tractor and harvest machine is wireless. Two ultrasound sensors coupled to the elevator and a microprocessor manage such information, generating a correct synchronization among the machines. The system was tested in laboratory and on field performing its function adequately, maintaining the two machines in synchronization, indicating and alerting the operators their relative positions. The developed system reduced the sugar cane lost in 60 kg ha-1 comparing to the harvest with the system turned off.

The MINUS system was developed as a minimally invasive procedure that uses a diaphyseal cephalic extramedullary implant for the treatment of transtrochanteral fractures of the femur in elderly patients. The implant consists of a sliding screw coupled to a plate adapted to the minimally invasive technique. The surgical access is approximately three centimeters in length located on the lateral surface of the hip, below the projection of the small trochanter. A perfectly adapted instrument was used for the procedure, which also requires the use of an image intensifier, reducing surgery time and rate of bleeding. The objective of this study is to present a new instrument and implant, developed specifically for treatment with the minimally invasive technique, reducing the length of the conventional surgical access from 10 to three centimetres. This new implant was given the commercial name of MINUS System.

Problems identified in the study and analysis of the phonology of Brazilian Indian languages belonging to the Macro-Jê branch such as Kaingang, Maxakali, and Mebengokre led the author to confirm the accuracy of some intuitions on the part of Piggott (1992) and Rice (1993) on dealing with relations between nasality and sonorancy (D'Angelis 1998). The applicability of the approach to the distinct processes of nasality and nasalization in Portuguese was verified with surprising results that recover some intuitions of Trubetzkoy (1939) and contribute to reconfirm the Mattoso Câmara's (1953; 1970) considerations, but at the same time go beyond them. This article presents the result of this investigation and its conclusions that suggest the validity and the necessity of reexamining even the phonemic inventory of the Portuguese language, an issue not at all questioned in the teaching of phonology, to take into account the linguistic changes in the phonological system of that language in the last fifty years.

This text which discusses the central theme of the National Conference on Education (CONAE), held in Brasília from 28th March to 1st April 2010, deals with the concept of a National System of Education in articulation with the National Plan of Education. To that end, after pointing to the basic uses of the concept of system, it discusses the question of the National System of Education exploring the federative question in order to reveal the complete compatibility of the organization of the National System of Education with the federative regime. Thereafter, it deals with the historical meaning of the National Plan of Education demonstrating that the plan is a demand of the system, since planned action is implicit in systematized education. Thus the National Plan of Education is fulfilling those goals and objectives for which it is responsible.

OBJECTIVE: To evaluate the positive predictive value for BI-RADS (Breast Imaging Reporting and Data System) categories 3, 4 and 5, correlating mammographic and histological diagnosis in non-palpable breast lesions. MATERIALS AND METHODS: Analytical-descriptive study of 169 women submitted to stereotactic localization for surgical biopsy of non-palpable breast lesions. Mammographic and histological findings were correlated, analyzing the predictive positive value for each category. RESULTS: Forty-two (24.8%) cases were diagnosed with breast cancer - only one in category 3, 19 in category 4, and 22 in category 5. The positive predictive value for categories 3, 4A, 4B, 4C and 5 were, respectively, 3.4%, 10.3%, 11.3%, 36% and 91.7%. Microcalcifications were the most frequent finding related to malignancy, present in 61.5% of these cases. CONCLUSION: The present study has demonstrated that BI-RADS allows a safe prediction of high suspicion of malignancy in lesions category 5 and low suspicion for category 3. As regards the category 4, the positive predictive value has shown a progressive increase in subcategories A, B and C, demonstrating that this subclassification represents an invaluable contribution for a more detailed and accurate assessment of lesions suspicious for malignancy.
