Multivariate analysis and extraction of parameters in resistive RAMs using the Quantum Point Contact model

A multivariate analysis of the parameters that characterize the reset process in RRAMs has been performed. The different correlations obtained can help to shed light on the current components that contribute in the Low Resistance State (LRS) of the technology considered. In addition, a screening method for the Quantum Point Contact (QPC) current component is presented. For this purpose the second derivative of the current has been obtained using a novel numerical method which allows determining the QPC model parameters. Once the procedure is completed, a whole RS series of thousands of curves is studied by means of a genetic algorithm. The extracted QPC parameter distributions are characterized in depth to get information about the filamentary pathways associated with LRS in the low voltage conduction regime.Spanish Ministry of Economy and Competitiveness TEC2014-52152-C3-2-R , MTM2013-47929-P (also supported by the FEDER program)IMB-CNM Spanish Ministry of Economy and Competitiveness TEC2014-52152-C3-1-R and TEC2014-54906-JIN (supported by the FEDER program)ENIAC Joint Undertaking-PANACHE project.Spanish ICTS Network MICRONANOFAB

Bovine milk production in Campeche: prospects and challenges for rural producers' development

Objective: To characterize at the municipal level the productivity of the bovine-milk sector in the state of Campeche; to determine the profitability of the sector and propose improvement schemes to add value to the commercialization of the product. Design / Methodology / Approach: From the Agricultural and Fisheries Information System, variables were obtained: Production (thousands of L), Price ($L-1) and Value of Production (thousands of$) from 2006 to 2018. Through multivariate statistics and analysis, the profitability of the bovine-milk sector from 2013-2018 compared to 2007-2012 was determined. The analyses were completed by an interview with 12 milk producers who gave added value through the manufacture of chesses. Results: A drop in profitability (-8.8%) was found in the sector from 2013-2018 compared to 2007-2012, despite the increase in production of 6.2% that did not compensate for the fall in prices (-14.2%). The regions with the highest productivity were located from the center to the south of the state: Champotón (24.62%), Escárcega (17.36%) and Campeche (16.63%). Limitations / Implications: Adding value to the milk commodity is a priority need in the short term, to avoid abandoning the activity, which could compromise the economy of rural producers. Findings / Conclusions: The Mennonite settlements in Campeche have managed to add value to the cattle-milk sector through the manufacture and sale of artisan chesses. However, the great challenge of the sector is the revaluation of artisan chesses with market strategies that encourage the consumption of local resources in a context of globalization.Objective: To characterize at the municipal level the productivity of the bovine-milk sector in the state of Campeche, Mexico; to determine the profitability of the sector and to propose improvement schemes in order to add value to the commercialization of the product.

Integración de recursos electrónicos en las bibliotecas del Consorcio de Bibliotecas Universitarias de Andaluzas (CBUA)

En los últimos años, el presupuesto en recursos electrónicos ha ido creciendo paulatinamente en las Bibliotecas Universitarias y como consecuencia las inversiones en este tipo de materiales han ido aumentando, convirtiéndose hoy día la Biblioteca Universitaria en una gran factoría virtual. El Consorcio de Bibliotecas Universitarias Andaluzas (CBUA) que asume entre sus políticas el desarrollo de proyectos para la mejora de la calidad de los servicios a través de la cooperación, consciente de esta situación, acomete el plan de dotar a las Bibliotecas del Consorcio de tecnologías centradas en el usuario, para hacer más accesibles las colecciones de recursos electrónicos y poder competir en la Europa del conocimiento con parámetros de calidad. Se presenta el proyecto que está llevando a cabo el Grupo de Trabajo de MAP y ERM del CBUA, de implementación y puesta en marcha de herramientas, para el acceso, integración y gestión de los recursos electrónicos en las Bibliotecas Universitarias Andaluzas, para un mejor uso de las colecciones digitales contratadas, que redundará en la calidad y mejora de los servicios prestados. Se enumeran las fases del proyecto, los objetivos operativos, las líneas de acción, las acciones realizadas, la documentación generada, la difusión y formación en las nuevas herramientas y la repercusión que está teniendo en las Bibliotecas del CBU

Estimating the Quantity of Non-Tariff Measures SADC Meat and Milk Trade

Global trade protection in the form of tariffs has been on the downward trend since the conclusion of the World Trade Organisation Uruguay Round of negotiations. The same pattern was observed in SADC as well as other regional integration groups. In SADC the declining trade protection was not accompanied by improvement in trade performance. If anything, the share of intra-SADC trade has actually declined during the phase down of tariffs in the eight year period. This study explores the possible reason for poor trade performance in the tariff reducing environment using meat and dairy markets as case studies over the period 2000 to 2010. It is hypothesised that non tariff measures (NTMs) are more trade restricting that tariffs. The statistics show that on average each agricultural product traded is affected by about ten NTM. These vary from country to country, with Mozambique having the highest incidence of NTMs, and the lowest being Malawi. On a product level, fruits are the most affected products with more about 40% of all NTMs applied. The gravity model was used to estimate intra-SADC trade and to evaluate the quantity impacts of NTMs on tariffs. The NTMs applied to meat products were found to be as high as 400% compared to roughly 200% for dairy. Furthermore, it was found that in the case of dairy tariffs and NTMs were used jointly as means of protection. This implies that there is a need to focus attention, both in research and policy on the NTMs
