Análisis de rentabilidad de la quinoa para el Ejido Paso Nacional

The middle and upper classes, aware of the importance of nutrition for their health, demand healthier foods. Current crops do not fully meet their nutritional and functional needs. Due to its high nutritional value, quinoa is considered an alternative that small producers can offer to these socioeconomic segments, thus increasing their income. The main objective is to analyze the profitability of this crop, compared to corn, in Ejido Paso Nacional, Tlachichuca, Puebla. This community was chosen due to its agro-climatic similarity to the origin of quinoa. Estimated costs and revenues were obtained from an experimental planting on two hectares for three consecutive years. Through the SAAFI financial software, the main financial indicators of quinoa were obtained: VAN = $607,358, TIR = 37.32$3.12, and TRDI = 4 years. It is concluded that quinoa cultivation is more profitable than corn cultivation under similar production conditions, and one hectare is needed to have an income above the poverty line.La clase media y alta, conscientes de la importancia de la nutrición en su salud, demandan alimentos más saludables. Los cultivos agrícolas actuales no satisfacen plenamente sus necesidades nutricionales y funcionales. La quínoa, por su alto valor nutricional, se considera una alternativa que los pequeños productores pueden ofrecer a estos segmentos socioeconómicos, aumentando así sus ingresos. El objetivo general consiste en analizar la rentabilidad de este cultivo, en comparación con el maíz, en el Ejido Paso Nacional, Tlachichuca, Puebla. Se eligió esta comunidad por su similitud agroclimática con respecto al centro de origen de la quínoa. Los costos e ingresos estimados se obtuvieron de una siembra experimental realizada en dos hectáreas durante tres años consecutivos. Mediante el software financiero SAAFI se obtuvieron los principales indicadores financieros del cultivo de quínoa: VAN= $607,358, TIR= 37.32$3.12 y TRDI= 4 años. Se concluye que el cultivo de quínoa es más rentable que el cultivo de maíz bajo condiciones similares de producción y se necesita una hectárea para poder tener un ingreso superior a la línea de bienestar de pobreza

Effectiveness of an intervention for improving drug prescription in primary care patients with multimorbidity and polypharmacy:Study protocol of a cluster randomized clinical trial (Multi-PAP project)

This study was funded by the Fondo de Investigaciones Sanitarias ISCIII (Grant Numbers PI15/00276, PI15/00572, PI15/00996), REDISSEC (Project Numbers RD12/0001/0012, RD16/0001/0005), and the European Regional Development Fund ("A way to build Europe").Background: Multimorbidity is associated with negative effects both on people's health and on healthcare systems. A key problem linked to multimorbidity is polypharmacy, which in turn is associated with increased risk of partly preventable adverse effects, including mortality. The Ariadne principles describe a model of care based on a thorough assessment of diseases, treatments (and potential interactions), clinical status, context and preferences of patients with multimorbidity, with the aim of prioritizing and sharing realistic treatment goals that guide an individualized management. The aim of this study is to evaluate the effectiveness of a complex intervention that implements the Ariadne principles in a population of young-old patients with multimorbidity and polypharmacy. The intervention seeks to improve the appropriateness of prescribing in primary care (PC), as measured by the medication appropriateness index (MAI) score at 6 and 12months, as compared with usual care. Methods/Design: Design:pragmatic cluster randomized clinical trial. Unit of randomization: family physician (FP). Unit of analysis: patient. Scope: PC health centres in three autonomous communities: Aragon, Madrid, and Andalusia (Spain). Population: patients aged 65-74years with multimorbidity (≥3 chronic diseases) and polypharmacy (≥5 drugs prescribed in ≥3months). Sample size: n=400 (200 per study arm). Intervention: complex intervention based on the implementation of the Ariadne principles with two components: (1) FP training and (2) FP-patient interview. Outcomes: MAI score, health services use, quality of life (Euroqol 5D-5L), pharmacotherapy and adherence to treatment (Morisky-Green, Haynes-Sackett), and clinical and socio-demographic variables. Statistical analysis: primary outcome is the difference in MAI score between T0 and T1 and corresponding 95% confidence interval. Adjustment for confounding factors will be performed by multilevel analysis. All analyses will be carried out in accordance with the intention-to-treat principle. Discussion: It is essential to provide evidence concerning interventions on PC patients with polypharmacy and multimorbidity, conducted in the context of routine clinical practice, and involving young-old patients with significant potential for preventing negative health outcomes.

Continuidad espectral

“La idea de espectro de un operador en la matemática contemporánea surge de diversos intentos ó de comprender problemas concretos de álgebra lineal que involucran la solución de ecuaciones lineales y sus generalizaciones a dimensiones infinitas. Sin embargo, esta visión es el resultado de la evolución matemática de una serie de ideas a lo largo de tres siglos. La teoríıa espectral es una rama fundamental de las matemáticas que ha tenido un fuerte impacto sobre el análisis matemático y, en particular, sobre el análisis funcional ya que esta ́ relacionado con resultados en las diferentes ́áreas como son ecuaciones diferenciales, ecuaciones integrales, sistemas dinámicos, mecánica cuántica entre otros.

Boundary value problems for the Schrödinger equation involving the Henstock-Kurzweil integral

summary:In the present paper, we investigate the existence of solutions to boundary value problems for the one-dimensional Schrödinger equation $-y''+qy=f$, where $q$ and $f$ are Henstock-Kurzweil integrable functions on $[a,b]$. Results presented in this article are generalizations of the classical results for the Lebesgue integral

Some results about the Henstock-Kurzweil Fourier transform

summary:We consider the Fourier transform in the space of Henstock-Kurzweil integrable functions. We prove that the classical results related to the Riemann-Lebesgue lemma, existence and continuity are true in appropriate subspaces
