Evaluation of producer inflation, subsidies and profitability of vegetables and grains in Sinaloa, 2018-2019

Objective: Evaluate producer inflation, equity in procampo support and profitability of eight agricultural products from Sinaloa, 2018-2019 cycle. Method: This document has three approaches; In the first, estimated the impact of inflation on the value of agricultural production, using the agricultural producer price index (INPP) base 2019. Second, using the Lorenz curves, equity is calculated or in the allocation of procampo - proagro. Third, calculated internal rate of return (IRR) for the eight products and compared with the 28-day yield of the treasury certificates (CETES). Results: The main crops in the state of Sinaloa are: cereals (corn, wheat), and vegetables (tomato, chili peppers). The current values ??generated in Sinaloa agriculture show growth. It is observed that there is an inflation gap that has been decreasing in the period 2000-2019. This implies that the transfer of prices from the producer to the consumer is less and less. It is noted that the profitability of the selected products is varied, vegetables with high rates and products such as corn and beans with low returns, even below the 28-day cetes. Limitations: this study does not specify the size of the productive unit and only the data is generalized. It does not address marketing channels and their destinations. Findings and conclusions: It is noted that there is a decrease in price transfers from the producer to the consumer, returns are also calculated and compared between crops and cetes. It is concluded that in the 2018-2019 period, corn and beans register lower profitability than if they were invested in CETES. Keywords: inflation, profitability, prices, performance.Objective: To evaluate producer inflation, equity in PROCAMPO subsidy distribution, as well as profitability of eight agricultural products in the state of Sinaloa, 2018-2019 cycle.Design/Methodology/Approach: First, inflation is estimated in the value of agricultural production, using the agricultural producer price index (INPP) base 2019. Second, the inequality in the allocation of PROCAMPO is calculated with Lorenz curves. Third, the internal rate of return (IRR) is estimated for the eight products and compared with the 28-day yield of the treasury certificates (CETES).Results: The current values generated show growth in cereals (corn, wheat), and vegetables (tomato, chili peppers), with downward inflationary gaps in the period 2000-2019. There is a concentration of the PROCAMPO allocation in producerswith high income deciles. The IRR is high in vegetables, and low in corn and beans.Study Limitations/Implications: This study does not specify the size of the productive unit and only the data is generalized. It does not address marketing channels and their destinations.Findings/Conclusions: The producer is assuming the inflationary increase. Income transfers via PROCAMPO areinequitable. The IRR in corn and beans is sometimes less profitable than CETES

Alaiz Experiment (ALEX17): Campaign and Data Report:NEWA Deliverable Report D2.21

This report ALEX17, the acronym for ALaiz EXperiment 2017, is the last full-scale experiment within the NEWA (New European Wind Atlas) project, whose primary objective is to create a wind atlas of Europe that includes the state-of-the-art in modelling the wind resource, as well as the creation of a comprehensive database. ALEX17 aims to present a utility-scale measurements campaign to characterize the wind flow in complex terrain, through a combination of measurement technologies. Having finalized the measurements campaign and processed all the information, the wind flow in the area of study can be characterized for different weather conditions. In addition, the experimental data will be able to validate the reliability of numeric simulation models of wind flow in complex terrain, in order to reduce uncertainties when evaluating the wind resource

Genomic Ancestry, CYP2D6, CYP2C9, and CYP2C19 Among Latin Americans

We present the distribution of CYP2D6, CYP2C9, and CYP2C19 variants and predicted phenotypes in 33 native and admixed populations from Ibero-America (n > 6,000) in the context of genetic ancestry (n = 3,387). Continental ancestries are the major determinants of frequencies of the increased-activity allele CYP2C19*17 and CYP2C19 gUMs (negatively associated with Native American ancestry), decreased-activity alleles CYP2D6*41 and CYP2C9*2 (positively associated with European ancestry), and decreased-activity alleles CYP2D6*17 and CYP2D6*29 (positively associated with African ancestry). For the rare alleles, CYP2C9*2 and CYPC19*17, European admixture accounts for their presence in Native American populations, but rare alleles CYP2D6*5 (null-activity), CYP2D6-multiplication alleles (increased activity), and CYP2C9*3 (decreased-activity) were present in the pre-Columbian Americas. The study of a broad spectrum of Native American populations from different ethno-linguistic groups show how autochthonous diversity shaped the distribution of pharmaco-alleles and give insights on the prevalence of clinically relevant phenotypes associated with drugs, such as paroxetine, tamoxifen, warfarin, and clopidogrel

Influencia de los conflictos familiares, presión de grupo y la necesidad de explorar, que induce a los niños de sexto grado de la Escuela Juan Valverde Mora al consumo de alcohol, durante el segundo trimestre del año 2006.

Licenciatura en Orientación.Investiga la influencia de los conflictos familiares, presión de grupo y la necesidad de explorar, que induce a los niños de sexto grado de la Escuela Juan Valverde Mora al consumo de alcohol, durante el segundo trimestre del año 2006. Es una investigación de tipo descriptiva. La población investigada está conformada por 31 estudiantes y 31 padres o encargados de los niños. Entre las conclusiones, se destaca que la influencia de los conflictos familiares en el consumo de alcohol son un factor sin influencia en el consumo de alcohol, sin embargo se cree que aspectos como la no comunicación en la familia y la violencia, influyen en forma negativa. Los padres clasificaron los conflictos como un factor de baja influencia, a pesar de que en el aspecto de la comunicación de pareja el resultado no fuese tan positivo y se muestran mayores coincidencias en las respuestas dadas por los estudiantes y los padres. En la influencia de la presión de grupo, en el consumo del alcohol se concluyó lo siguiente: Es un factor de influencia moderado, a pesar que en el aspecto de la influencia de los medios de comunicación en los niños, se definiera como influencia alta. Para los padres de familia la influencia de los conflictos familiares es un factor de baja influencia. En la Influencia de la necesidad de explorar en el consumo de alcohol, se concluyó lo siguiente: La necesidad de explorar, en el consumo de alcohol, en los niños, es un factor que influye en un nivel moderado, aspectos como el no conversar en la casa sobre los efectos nocivos del licor y que la población presente síntomas de ansiedad, puede influir en el resultado obtenido. La variable de mayor influencia en el consumo de alcohol en los estudiantes, es la necesidad de explorar. Para los padres de familia este objetivo es de influencia baja. Los encargados de familia de los niños de sexto grado de la Escuela mencionada no clasifican a ninguna de las variables investigadas como factor de influencia en el consumo de alcohol.It investigates the influence of family conflicts, peer pressure and the need to explore, which induces sixth grade children of the Juan Valverde Mora School to consume alcohol, during the second trimester of 2006. It is a descriptive research. The research population consisted of 31 students and 31 parents or guardians of the children. Among the conclusions, it is highlighted that the influence of family conflicts on alcohol consumption is a factor without influence on alcohol consumption; however, it is believed that aspects such as non-communication in the family and violence have a negative influence. Parents classified conflicts as a factor of low influence, despite the fact that in the aspect of couple communication the result was not so positive and there is greater coincidence in the answers given by students and parents. In the influence of peer pressure on alcohol consumption, the following was concluded: It is a factor of moderate influence, despite the fact that in the aspect of the influence of the media on children, it was defined as a high influence. For parents, the influence of family conflicts is a factor of low influence. In the Influence of the need to explore in the consumption of alcohol, the following was concluded: The need to explore, in the consumption of alcohol, in children, is a factor that influences at a moderate level, aspects such as not talking at home about the harmful effects of liquor and that the population presents symptoms of anxiety, can influence the result obtained. The variable with the greatest influence on alcohol consumption among students is the need to explore. For parents, this objective has a low influence. The caregivers of the sixth graders at the aforementioned school do not classify any of the variables investigated as a factor of influence on alcohol consumption.Universidad Nacional, Costa RicaSede Regional Brunca, Campus Pérez Zeledó

Validación de una técnica para la determinación de toxinas paralizantes en moluscos bivalvos de Costa Rica mediante cromatografía líquida acoplada a reactor post columna con detector de fluorescencia

Chromatographic and extraction conditions were implemented and validated for the determination of twelve paralytic toxins (PSP) in bivalves, including STX’s (saxitoxins), GTX’s (gonyautoxins) and C’s (N-sulfocarbamoyl gonyautoxins). The extraction method of Rourke et al. [1] was tested and modified using an acid extraction in 0.1 M HCl and 30 m/v trichloroacetic acid in the purification step. The chromatographic methods proposed by Rourke et al. [1] and Franco and Fernández [2] were evaluated. The validation was performed for the first method mentioned [1]; a gradient program is established for the separation of STX’s and GTX’s toxins, and an isocratic method for the separation of C’s. The established method was further validated by determining the correlation coefficient (R) (0.995-1.000), coefficient of determination (R2) (0.989-1.000), linear range (53.7-926.6 μg STX diHCl equivalents/100 g), sensitivity (4.32-60.32 LU (μmol/L)-1), recovery percentage (58-115%), coefficient of variation (2-17%) for instrumental repeatability and (2-16%) for methodological repeatability, sensitivity (limits of detection (LODs)): 1.1-8.5 μg/100g and limits of quantification (LOQs)): 1.60-12.6 μg/100g. The application of this method proved good performance and capability for simultaneous determination of PSP toxins in bivalve molluscs.Se implementaron las condiciones cromatográficas y de extracción para la validación de una técnica para la determinación de doce toxinas paralizantes (PSP), incluyendo los grupos STX’s (saxitoxinas), GTX’s (gonyautoxinas) y C’s (N-sulfocarbamoil gonyautoxinas) para moluscos bivalvos. Para la metodología de extracción se evaluó y modificó la propuesta de Rourke et al. [1], utilizando una extracción ácida en HCl 0,1 M y ácido tricloroacético 30 m/v en la etapa de purificación. Posteriormente se evaluaron y modificaron los métodos cromatográficos propuestos por Rourke et al. [1] y Franco y Fernández [2]. La validación se realizó para el primer método citado [1], en el cual se establece un programa en gradiente para la separación de las toxinas STX’s y GTX’s, y un método isocrático para la separación de C’s. La validación del método determinó un coeficiente de correlación (R) 0.995-1.000, un coeficiente de determinación (R2) 0.989-1.000 y un rango lineal de 53.7-926.6 µg STX diHCl equivalentes/100 g. La sensibilidad se determinó en 4.32-60.32 LU (µmol/L)-1, el porcentaje de recuperación entre 58-115%, el coeficiente de variación entre 2-17% para la repetibilidad instrumental y 2-16% para repetibilidad metodológica. La sensibilidad (límites de detección (LODs)): 1.1-8.5 µg/100g; límites de cuantificación (LOQs)): 1.60-12.6 µg/100g. La aplicación de esta metodología demostró un buen desempeño y capacidad para la determinación simultánea de toxinas PSP en moluscos bivalvos.  &nbsp
