Diversidad de árboles, aves y la regulación de los ecosistemas

LUIS ALEJANDRO ABDALA ROBERTS (2023, [Artículo])

La diversidad de especies de árboles medida, por ejemplo, como el número de especies que cohabitan un sitio dado, afecta a animales que hacen uso de los bosques y la manera en que estos interactúan con plantas y otros animales. Estudios han encontrado que un aumento en la diversidad arbórea, favorece la abundancia y diversidad de depredadores como, por ejemplo, aves insectívoras, lo cual resulta en mayores niveles de depredación por estas sobre insectos herbívoros y consecuentes beneficios a las plantas y al ecosistema en su conjunto.

LUCHAS EN DEFENSA DE LA VIDA. CRIMINALIZACIÓN COMO ESTRATEGIA NECROPOLÍTICA EN CONTRA DE LAS Y LOS LIDERES SOCIALES DEL CONGRESO DE LOS PUEBLOS

Julián Andrés Gil Reyes (2023, [Tesis de maestría])

"Este trabajo tiene como objetivo principal analizar los procesos de criminalización desarrollados contra un líder y una lideresa social del congreso de los pueblos de las regiones de Arauca y sur de Bolívar durante el periodo 2015-2022, buscando comprender las estrategias necropolítica de criminalización y judicialización que han vivido y las duras amenazas que actualmente enfrentan contra sus vidas. Esta tesis es entonces un esfuerzo por narrar la realidad de las y los líderes sociales en Colombia desde su propia voz, un tema que ha sido poco explorado desde los espacios académicos, dados los altos riesgos para la vida que representa la denuncia o investigación de estos temas. Sin embargo, es imperativo ético, académico y político aportar estas reflexiones que pueden ser significativas para los movimientos sociales de Colombia y otros lugares que padecen situaciones similares, así mismo ubica una pieza más en el puente entre la academia y los movimientos sociales".

Universal fixation system for pad printing of plastic parts

JOSE ALEJANDRO FERNANDEZ RAMIREZ (2023, [Artículo])

Pad printing is used in automotive, medical, electrical and other industries, employing diverse materials to transfer a 2D image onto a 3D object with different sizes and geometries. This work presents a universal fixation system for pad printing of plastic parts (UFSP4) in response to the needs of small companies that cannot afford to invest in the latest technological advances. The UFSP4 comprises two main subsystems: a mechanical support system (i.e., support structure, jig matrix and braking system) and a control system (i.e., an electronic system and an electric-hydraulic system). A relevant feature is the combination of a jig matrix and jig pins to fixate complex workpieces with different sizes. Using finite element analysis (FEA), in the mesh convergence, the total displacement converges to 0.00028781 m after 12,000 elements. The maximum equivalent stress value is 1.22 MPa for the polycarbonate plate in compliance with the safety factor. In a functionality test of the prototype performed in a production environment for one hour, the jigs fixed by the plate did not loosen, maintaining the satisfactory operation of the device. This is consistent with the displacement distribution of the creep analysis and shows the absence of the creep phenomenon. Based on FEA that underpinned the structural health computation of the braking system, the prototype was designed and built, seeking to ensure a reliable and safe device to fixate plastic parts, showing portability, low-cost maintenance and adaptability to the requirements of pad printing of automotive plastic parts.

Wheat seed demand assessment assisted by genotyping in Ethiopia

Moti Jaleta Kindie Tesfaye Olaf Erenstein (2023, [Artículo])

This study examines the extent to which wheat varieties supplied by the formal seed system align with the varieties demanded and used by farmers in Ethiopia. The framework of stated and revealed preferences drawn from the consumer preference theory is used to analyze farmer demand for different wheat varieties. We used official data from the formal seed sector and representative survey data from wheat farm households in Ethiopia. The survey data allow to contrast the farmer reported varietal use with genotyping by sequencing (also known as DNA fingerprinting). Farmers' reliance on informal seed sources and own saved seed, among others, contributes to the misidentification of the varieties they grow. Consequently, farmers are likely to misinform the formal seed demand assessment leading to either an over- or underestimation of actual seed demand for specific wheat varieties. Genotyping by sequencing, as opposed to farmer reports, established the persistence of old varieties. This also implies vulnerability of wheat production to disease dynamics depending on the longevity of disease resistance by the variety in use. Apart from narrowing the gap between the actual and stated demand and ensuring timely replacement of wheat varieties, genotyping-assisted estimates can save seed carry-over cost. Genotyping by sequencing is increasingly used as the new benchmark and gold standard for identifying and tracking the adoption of crop varieties. The technique has potential to enhance the performance of the seed sector through effective planning that can optimize resource commitments and accelerate the rate of varietal replacement.

Local markets and food security. The case of the Milpera and Puuc regions in Yucatan

Ana Laura Bojórquez Carrillo Monserrat Vargas Jiménez Mireya Noemi Hernández Islas (2023, [Artículo, Artículo])

Food insecurity is a complex problem worldwide. A major part of this problem is the food supply. Local markets can represent a strategy for building social capital, as well as strategies for subsistence and sustainability of food value chains, contributing to food security and its effects. The objective of this research is to determine if the existence of a municipal market in the Milpera and Puuc regions of Yucatán favors the existence of food security, the consumption or the expense of natural foods. The population is located in 18 municipalities of Yucatán, Mexico. To carry out this study, a cross-sectional, non-experimental study, with a quantitative approach and correlational scope. The main techniques that were applied were descriptive statistics and contingency tables with respect to 6 hypotheses. This work shows that the existence of markets in the communities makes a significant difference because it positively impacts the food security of the inhabitants, since it allows them to have access to a wider variety of products and at the same time, favors the active dynamics of the economy of the community.
