Benemérita Universidad Autónoma de Puebla posted this:PROCESS FOR PERFORMING TRANSESTERIFICATION REACTIONS USING ANIONIC CLAYS AND RESULTING PRODUCTS.The present invention refers to a process for performing transesterification reactions, mainly for obtaining alkyl ester from fatty acids and/or glycerine, more particularly for producing biodisel, which comprises the following stages: reaction of animal fats and/or vegetable oils either pure or used, with an alcohol at a temperature of from about 40 DEG C to about 300 DEG C in the presence of a catalyst that comprises the mixed oxides M2+OM3+2O3, M2+OMp+2OpM3+2O3 or mixtures thereof, where M2+ is a divalent cation, M3+ is a trivalent cation and Mp+ is at least a divalent or trivalent cation or a mixture thereof obtained by the calcination of materials, where the catalyst, previous the activation to be used as a catalyst, presents the X-ray diffraction pattern characteristic of the anionic clays which have a molar ratio M2+/M3 of 1 to 10, thus forming alkyl esters from fatty acids which are separated from the alcohol without reacting and from the glycerine, by decantation, filtration, centrif ugation and/or solid-liquid extraction.
aws-Austria Wirtschaftsserviceges.m.b.H. posted this:FRIDS - Moisture–regulating indoor insulation system to improve energy efficiency of old buildingsOld buildings present a special challenge since it is often only possible to insulate them from the inside (e.g. at classified historical monuments). Furthermore, old buildings frequently suffer from damp and condensation problems. FRIDS is an indoor insulation system that guarantees heat insulation and moist removal sustainable solution for ground-contact wall fragments, fire walls, reveals, etc. and offers a permanent solution to this problems.
University of Huelva posted this:Measurement system for the identification and accurate determination of distorting loads in electrical networks and microgridsThe only measurement of distortion level in a network can highlight the need for action to control it. Among those actions is, for example, the use of power filters. However, the determination of the most suitable point where the filter must be connected and its most appropriate configuration requires further analysis of the micro-network (a subset of nodes in the network with different loads connected to each). Therefore, an additional study becomes necessary to establish the responsibility of each load in global distortion levels. In addition, the establishment of the model of the most responsible loads is also necessary in order to decide the filter configuration. In this sense, the load may be voltage distorting or current distorting. All this information is provided by the device of the invention. Indeed, the device, besides distributing the responsibility for overall levels of distortion between each agent, reports whether loads are voltage harmonics or current harmonic sources. This information is the most relevant to determining the power filter settings that best mitigate the distortion in each network node.
Fundació URV posted this:ELECTRE-H software package: a tool for data analysis and decision aiding with hierarchical criteriaThe ELECTRE-H Software Package implements two new methods for ranking and ordered classification decision problems considering multiple criteria structured into a hierarchy. The hierarchy of criteria is a tool that allows the decision maker to better organize the problem based on its domain knowledge and needs, decomposing the general problem into smaller sub-problems. Both methods follow the well-known outranking model and belong to the family of ELECTRE methods. The ELECTRE approach is inspired on the voting-like procedure based on the opinion of the majority but also respecting the minorities (by allowing veto power). The software available to use ELECTRE methods does not allow a hierarchical decomposition of the problem, but on a flat organization of criteria. The ELECTRE-H for hierarchical sets of criteria was defined by Dr. Del Vasto and Dr. Valls (from URV) and Dr. Slowinski and Dr. Zielniewicz (from Poznán University of Technology, Poland). The papers can be found here: http://www.sciencedirect.com/science/article/pii/S0957417415001153 http://link.springer.com/article/10.1007/s10844-015-0362-7 The novelties of these two methods are the following: -It fully applies the standard outranking procedure of ELECTRE at all the levels of the hierarchy of criteria (concordance and discordance indices are obtained from the results of the previous layer and exploited at each node to generate new results). -The user will get a result (a ranking or classification) at each intermediate node of the hierarchy as well as the root (or overall) node. -Preference uncertainty can be managed at each node of the hierarchy with its particular discrimination threshold values. -Veto power can be given to the appropriate nodes in the hierarchy, to avoid compensation with the rest of related criteria. -Different scales of measurement can be used both in the elementary criteria and in the intermediate criteria. -For the case of sorting, simple IF…THEN… decision rules are used to define the categories. The novelty of the software ELECTRE-H is that it is the implementation of these methods given by the authors. This guarantees that the program is fully following the methodology proposed. Its main features are: -Clear and easy-to-understand user interface. -Data can be easily provided using an Excel file. -All the parameters of the model can be easily changed in the user interface. -The results obtained can be graphically displayed (i.e. partial pre-orders, rankings) and exported into a PNG image or text files. Also, the calculations of the results are provided in log files. -Additional statistical tools to compute correlations for different ranking and classification results on the same set of alternatives and hierarchy are available. - A distance-based statistical tool to compare partial preorders is available. -The “Simos revised procedure” to calculate numerical values for criteria weights is available. -Analysis of the results can be done at different levels of the hierarchy. -The software supports large number of alternatives and criteria. Also the structure of the hierarchy is only limited to be a tree (each node has a single parent). The software is designed to be easy to use while providing the full functionality required in these two methods.

UNIVERSIDAD DE ALICANTE posted this:Laboratory device to measure gas diffusion coefficients at real conditions.The Applied Petrology Group of the University of Alicante has developed an automatic device and a method to determine gas diffusion coefficients of single gases from a gas mixture under atmospheric conditions. The device works in a wide range of relative humidity and temperature and can be employed to test any permeable or porous material. The procedure allows to calculate the gas diffusion coefficients for samples with different size and nature (soils, rocks, concretes, synthetic materials, etc.). It is a non-destructive test that can be used to calculate the gas diffusion coefficients of more than one gas at the same time. It is looking for companies that are interested in this technology for its commercial exploitation.

It is useful for the connection of a distributed generation system to a bipolar DC grid. For these applications, the proposed topology is a solution with sufficient guarantees of reliability, quality and performance. The converter circuit is very simple, it includes three inductors, four capacitors, two diodes and a power switch as a switching device.

The determination of the magnetic disturbance component is especially relevant in cases of sporadic but explosive solar phenomena. From the perspective of the actual user, the present invention constitutes an essential element in the risk management of the effects of solar activity on vulnerable technologies, both ground-based and satellite-based (electric power, rail transport, terrestrial and positioning navigation systems, radio and satellite communication systems ...), increasing the capacities of public administrations, civil protection and emergencies and the companies themselves, in order to prepare a successful strategy for adverse conditions related to the solar activity. The group is looking for collaboration and/or commercial agreements with the Central Administration, Civil Protection, Critical Infrastructure, Electric Power companies, Rail Network, Oil pipelines companies, Gas Pipelines companies, Insurance firms, etc...
