The objective of the research was to determine the exposure to particulate material in the textil area of a manufacturing company of linens and duvets, where it is carried out measurements of particulate material in respirable fraction 2.5 μg/m3. The same were made through the use of the equipment of direct reading and the results are compared with the value set limit. The study found that in the operation with the overlock machines is where there is a greater amount of particulate matter getting the maximum value in the entire production plant of 244 μg/m³, and a lower value machine in the bender with a value of 9 μg/m³ During the course of the investigation, it wanted to know the perception of the employees, to do this a survey was administered in a manner that takes first-hand the opinion with regard to the work. Among the results is that the staff is aware that there is particulate matter and if you have had respiratory complaints, indicate that the organization presents a great deal of commitment to the security and they also are involved in the tasks.

This paper presents the oil deposit and operational variables that influence the implementation of the Steam Assisted Gravity Drainage (SAGD) process for the Production of Heavy and Extra-heavy Crude Oil. This process consists of drilling two parallel horizontal wells, one above the other, where the upper well is used for steam injection and the lower well is used for production. The efficiency of the process is greatly affected by the deposit and operating parameters (vertical spacing of wells, injection pressure, preheating period, among others). Furthermore, the prediction of the maximum rate of oil extraction was determined using an example with currently available real data of Block 20 of the Pungarayacu Field.

Three levels of paste Plukenetia volubilis (Sacha Inchi) consisting of 10, 15% and 20% were evaluated to replace the weight percent lard conventionally used to improve the nutritional quality of the common hamburger, compared with a reference group. The experimental units were 10 burgers, weighing 100 g. each and a total of 120 were analyzed in a completely randomized design with three replications. The research was conducted in the Universidad Estatal Amazónica and bromatológics and microbiological analyzes to determine the quality of the raw material and products are made in laboratory of the Faculty of Chemical Sciences of the Universidad Central del Ecuador. As supplements sensory tests and studies Benefit / Cost performed. The results show the variation of 10% pulp Sacha Inchi as the most recommended for use in industry.

This work recreates a proposal to evaluate the usage of different books categories in a university library. The model employs a mechanism to carry out usage statistics and a mechanism to carry out discovering association rules, from use data stored in the library system. Usage statistics are computed based on the degree of importance, or relevance, with respect to an area of knowledge, and association rules provide support to determine the final use of the various categories. In the process we take into account that stored data correspond to books requested on loan, renewal or consultation. The study presents knowledge discovery in data, aiming to enhance the management of a university library

The current research suggests that using of agile methodologies in conjunction with open source software tools can improve productivity, reduce costs and optimize resources in the process of software development, and helps improve user satisfaction due to implementation of excellent quality software. The following analysis shows the most important variables for the successful implementation of IT development projects and their relation with the use of traditional and agile software development methodologies.
