In this work, the effect on the addition of oatmeal (Avena sativa) and passion fruit (Passiflora edulis) in the content of fiber, calcium, iron, phosphorus and A vitamin in beverage formulation based on pumpkin (Cucurbita maxima), milk and whey, was determined. The beverages undergone significant changes during the storage time, the pH decreased as the acidity showed a slight increase. The coordinates of CIELAB (L *, a * and b *) were located in quadrant 1 indicating a clear tendency to yellow caused by the presence of carotenoids from the pumpkin and passion fruit. Based on the sensory analysis it was selected best treatment who was higher in 3 of the 4 parameters evaluated. This sample also presented a pseudoplastic behavior with a consistency index of 3.57 Pa.s0.24 and a shelf life of 9 days

The aim of this work is to select residual biomass from the Arequipa Region for the production of biofuels (biodiesel, bioethanol and biogas). In each case, the initial point is a matrix based on products with residual biomass available in the region, from the agricultural and livestock sectors, information that was obtained from the regional Management of Agriculture web site. Specific factors of the resudue that will be used as raw material for each biofuel production would be considered for the selection process. For the production of biodiesel it is necessary to start from the oil extracted from oilseeds. Regarding obtaining bioethanol, it requires that the residual biomass has high percent of cellulose. With regard to the generation of biogas, we will use animal droppings. Finally, the raw materials selected are: squash and avocado seeds for biodiesel, rice chaff and deseeded corncob for bioethanol and cow and sheep droppings for biogas

The present article relates concepts and knowledge on the international tendency as for the administration and improvement of the managerial processes. In the methodology review and analysis published online access, indexed database and other Web of Science is considered to identify those aspects of interest that influence the performance of companies and their processes. The main findings indicate that today any attempt to formalize the management and process improvement must contain theoretical assumptions about process management and system integration, it is also imperative to accept the basis of good management practices, treated with a focus process, highlighted in the selection process, the identification and assessment of opportunities for improvement, indicators and its relationship with business strategies

The watershed as the basic territorial unit of planning and management of water resources, requires its proper delimitation of the catchment or drainage area, faced with this situation, the lack of geographic information of Casacay river micro watersheds, hydrographic unit should be resolved, for this purpose the research was aimed at automatic delimitation of micro watersheds using of Geographic Information Systems (GIS) techniques and the project Shuttle Radar Topographic Mission (SRTM) 30 meters spatial resolution data. The selected methodology was the Pfafstetter one, with which nine micro watersheds were obtained with their respective codification allowing to continue with watersheds standardization adopted by Ecuador Water s Secretariat. With the investigation results watersheds will be updated with more detail information, promoting the execution of tasks or activities related to the integrated management of the hydrographic unit studied

In Ecuador, a factor of great ecological wealth is linked to its tradition in the use of fibers and other organic waste composite character as filler element, reinforcement or insulation in the field of housing construction, which carries great potential under the most viable architecture. The climate variability in Ecuador and the low purchasing power of their inhabitants forced to use local available building materials inexpensive or at no cost, in order to achieve economic and comfortable housing. That is why we have analyzed the presence of natural resources and waste biomass confronting regional building tradition, later superimpose geographically with major climatic variables affecting energy efficiency. This makes it possible to determine what, where and how to use the different biomass resources to allow a response to build that has a strong social, economic, environmental and energy argument in order to facilitate the conditions for access to economic habitat efficient, safe and dignified

This paper provides a detailed description and all the procedures involved in designing a power amplifier using microstrip technology and the design software Microwave OfficeTM. Specifically, the design is oriented to build an amplifier with central frequency at 14 GHz, but the same fundamentals and principles could be applied in the whole range of radio frequency. For the design, a MESFET transistor and simultaneous input and output matching networks are considered. The values of the parameters and the simulation for every stage are computed and performed using AWR Microwave OfficeTM. At the end of the document, a fully functional circuit layout represented in 2D and 3D is shown with all their complementary elements

This research comprises monitoring, assessment and recommendations for chemical risk originating from organic vapors (benzene, toluene and xylene) of fuel (super and extra gasoline) to which attendants at a gas station are exposed. Given the concentration measured of organic vapors (benzene, toluene and xylene) the chemical risk to which attendants are exposed in the supply area is acceptable. Control measures are recommended to ensure healthy working conditions for gas station attendants and also to avoid occurrence of occupational diseases in the medium or long term

Concrete plants are important to the economy of a country. However, this industry causes major environmental impacts in each of the steps involved in the manufacturing process of concrete production which are analyzed in this research. In addition, the perception of experts and workers in the area, about the environmental impacts associated with the activity of a producer of concrete was evaluated. The methodology used for the analysis of steps in the production process was as kind documentary. For to evaluate perception of environmental impacts the methodology used was descriptive non experimental, using interviews with workers related to the manufacturing process of the concrete. Among the major identified environmental impacts are dust emissions and improper handling of effluents, hazardous and non-hazardous materials. Among the proposals put forward to address these impacts include: installation of dust collectors, settling tanks, management plans for hazardous and non-hazardous materials, among others. An analysis of the results incorporating the principles of corporate social responsibility for improving or minimizing adverse impacts are detected proposed
