Megastore is one of the building blocks of Google’s data infrastructure. It has allowed storingand processing operations of huge volumes of data (Big Data) with high scalability, reliabilityand security. Companies and individuals using this technology benefit from a highly availableand stable service. In this paper an analysis of Google’s data infrastructure is made, startingwith a review of the core components that have been developed in recent years until theimplementation of Megastore. An analysis is also made of the most important

In May 2012, using a 30x30 cm surface and 0.5 mm aperture Surber net in the rivers: PindoMirador, Pindo Grande and Alpayacu, located in Mera, Pastaza, Ecuadorian Amazonia, thediversity and abundance of macro invertebrates was analyzed applying the BMWP/Col and theEPT indexes. It was determined the good Pindo Mirador, Pindo Grande and Alpayacu rivers’water quality, as well as the bad Alpayacu river’s water quality. This work provides an overviewof the environmental situation of aquatic ecosystems near Pindo Mirador Biological Station, ithighlights the importance of the rivers’ micro-watersheds near Pindo Mirador Biological Station,used as water source by the populations living downstream, and shows how macroinvertebrates can be used as bioindicators for the water and forests quality.

The company "Products Alexander" snack manufacturer in the city of Quito, has a production system that cannot supply customer orders, with a customer service index of 89,58%, also their processes are working with capabilities that are not properly programmed in given this reason the objective of this research is to propose a system of continuous improvement to increase production and make effective the snacks of chips using the Theory of Constraints (TOC) as a scientific methodology is to focus on solutions to critical problems of enterprises so that they approach their goal through a process of continuous improvement (Arias, 2006). The measurement was carried capacity of each of the operations which compose the preparation of snacks and identified restriction in the frying process, which was not working 100% of the daily time thereby limiting the ability of the factory, so we chose to exploit the constraint to eliminate it.The proposal made to exploit the constraint is a better production scheduling, reducingtransfer batch process to process, scheduling the amount of work for each of the operators inthe day, the preparation process and setting shifts at lunchtime for workers helping tostreamline the process of frying and allow work to full capacity 100% of the time. This proposalcan be considered as a solution to problems and improve production levels of the company,considering that based on indicators of TOC net income the company would increase from $ 15333.09 $ 17 392.14 in meeting quantity time and all customer orders.
