This research work starts with the question: What would be the reason why our compatriots choose to live in vulnerable areas, exposing their own life and that of their relatives? This question is relevant because it affects millions of compatriots (36% of the population, according to the Ministry of the Environment) and is applicable to any part of Peru. To answer the question an explanatory model is proposed, indicating variables of analysis, and their possible relationships, to make simulations, from the model. It is necessary to consider that the objective of the simulations is not to provide exact results, but to describe possible future behaviors, considering the actions that we take in the present. The proposed model considers a horizon of 50 years, and indicates that only if the problem is treated intensively the percentage of people in vulnerable areas could be reduced after a de...

Se propone una nueva modalidad de entrega que comparamos con la actual. Ésta consiste en compartir recursos, los repartidores, entre tiendas con el fin de reducir la variabilidad de la demanda y optimizar su utilización. Se hace la hipótesis que esta nueva modalidad puede reducir los costos de contratación, reduciendo la cantidad de repartidores para lograr el mismo nivel de servicio que se tiene, utilizándolos más eficientemente. El costo total de la operación se resume en tres componentes: el de contratar, el cual es variable según la cantidad de repartidores; el costo esperado por la pérdida de las órdenes que se entregan fuera del tiempo establecido con el cliente, el cual disminuye con la cantidad de repartidores y el costo adicional por el traslado de los repartidores entre tiendas para cubrir la demanda necesitada, el cual incrementa según se compartan más los recursos...

The ultrasound has solved the problem of the placentae localization, Still the high cost of ecography attempts its massification. But in this technique we count with equipments that taking advantage of the. Doppler effect inolate the acoustic reflection with notable economic advantage and simplicity in its management that also permits its high diffusion. In the beginning Doppler was used to get cardiac sound of the fetus. Besides this sound, we can appreciate others with this instrument where the placentae blow is an important one. While getting it, we supposed that it was possible to delimit the placentae contour which projection was drawn on the abdominal wall by "map out". The investigation has been taken in the Hospital Docente of Trujillo in a group of 50 pregnants that for got surgical interventions.

The concentration of heavy metals in cocoa crops is currently a serious problem for farmers and producers in various regions of Peru. Exports of cocoa and its derivatives to European markets are threatened by possible evidence of heavy metal contamination in exportable cocoa beans, some at levels higher than those permitted by food regulations established by the European Community, which are aimed at protecting consumers. It is considered that the possible reasons for the contamination of the Cd in cocoa crops may come from natural activities such as volcanic activities, erosion processes and sedimentation in rocks that contain minerals with a high content of these heavy metals. This contamination is also produced by anthropogenic activities such as mining of associated deposits, agriculture (use of fertilizers), smelting of minerals and burning of fossil fuels. Currently, there is no in...

A poco tiempo de empezar el nuevo milenio, los problemas derivados del aprovechamiento y la distribución de la tierra en el departamento de Puno, ubicado en la sierra sur del Perú, parecen no tener solución. En las páginas que siguen intentaremos dar una mirada de conjunto a la problemática que afecta a esta vasta y hermoso región del altiplano peruano; hermosa, pero también poco propicia para el desarrollo de la agricultura y de las propia vida humana. Como muchos de los problemas más complejos que afectan a la sociedad, la realidad de Puno no puede entenderse sin mirar a su historia, plena de detalles en el caso de la tierra, especialmente a todo lo largo de este siglo.

The objective of this investigation is to test the hypothesis of the possible association of one or more microsatellites located on 425-4933 with NSCLP. In this study a sample of 51 extended pedigrees were analyzed. From these pedigrees a sample of 51 caseparents trios was obtained. A novel genetic analysis was carried out using the Extended Transmission Disequilibrium Test (ETDT). Also a case control study was carried out with the 51 probands of the case-parents trios plus a sample of 94 controls of the Chilean population to test if differences were observed resulting from the methods used for the association studies. Microsatellites D4S1570, D4S1615, FGA, UCP1 and D4S1597 located in 4q were analyzed. The polymerase chain reaction (PCR) was used for analysis of DNA. Forward primers were marked with fluorescent-dye-label. Electrophoresis and analyses were carried out in an ABI PRISM 377 ...

The vehicle routing problem is one of the most studied problems in Operations Re-search. Different variants have been treated in the past 50 years and with technological advances, new challenges appear. In this thesis, we introduce a new variation of the VRP appearing in wireless networks. The new characteristic added to this well-know problem is the possibility of pick-up information via wireless transmissions. In the con-text considered here, a unique base station is connected with the outside and a vehicle is responsible for collecting information via wireless connection to the vehicle when it is located in another sufficiently close station. Simultaneous transmissions are permitted. Time of transmission depends on the distance between stations, the amount of infor-mation transmitted, and other physical factors (e.g obstacles along the way, installed equipment). Information to be sent...
