Arcos laminados para invernaderos [PDF]

Ciencia & Investigación Forestal, 1987
La ventaja de los invernaderos cuya estructura estaba constituida por arcos de madera laminada encolada radica en la duración de su vida útil, superior a la de materiales alternativos, en la facilidad de montaje, en la reducción de los costos y en la posibilidad de proporcionar las luces y alturas requeridas como para introducir elementos de trabajo ...

Can heterosis and inbreeding depression explain the maintenance of outcrossing in a cleistogamous perennial?

American Journal of Botany, Volume 110, Issue 10, October 2023., 2023
Abstract Premise What maintains mixed mating is an evolutionary enigma. Cleistogamy—the production of both potentially outcrossing chasmogamous and obligately selfing cleistogamous flowers on the same individual plant—is an excellent system to study the costs of selfing.

Energy analysis of drying basil (Ocimum basilicum) leaves in an active greenhouse solar dryer

Journal of Food Process Engineering, Volume 46, Issue 3, March 2023., 2023
Abstract The need for better utilization of solar greenhouses during summer in the hot climate conditions of Mexico led to the development of the concept of active greenhouse solar dryers. The objective of this research was energy analysis of an active greenhouse solar dryer for basil leaves drying.

Report of the Scientific Committee of the Spanish Agency for Food Safety and Nutrition (AESAN) on sustainable dietary and physical activity recommendations for the Spanish population

Food Risk Assess Europe, Volume 1, Issue 1, March 2023., 2023
Abstract Dietary recommendations are developed from the best available scientific evidence on the effect of nutrients and food on health. These recommendations take into account that the effect of food depends not only on its nutritional content but also on the matrix in which is ingested, the alterations during the culinary process, the presence of ...

Combined impacts of future climate‐driven vegetation changes and socioeconomic pressures on protected areas in Africa

Conservation Biology, Volume 36, Issue 6, December 2022., 2022
Abstract Africa's protected areas (PAs) are the last stronghold of the continent's unique biodiversity, but they appear increasingly threatened by climate change, substantial human population growth, and land‐use change. Conservation planning is challenged by uncertainty about how strongly and where these drivers will interact over the next few decades.

Implementación de un microprocesador basado en Arduino para el monitoreo de variables ambientales en invernaderos [PDF]

, 2023
En el país, los pequeños y medianos agricultores no suelen invertir en tecnologías para monitorear el ambiente de los invernaderos, lo que muchas veces aumenta el riesgo de pérdidas en la producción.

How seeds and growth dynamics influence plant size and yield: Integrating trait relationships into ontogeny

Journal of Ecology, Volume 110, Issue 11, Page 2684-2700, November 2022., 2022
Our results provide important insights into the proximal mechanisms that operate during ontogeny and drive variation in mature plant size in annual herbs. Of the three traits considered (a), seed mass and duration of vegetative growth had the greatest influence on plant size at maturity (b).

Climate change adaptation in Central America: A review of the national policy efforts

Latin American Policy, Volume 13, Issue 2, Page 276-327, November 2022., 2022
Abstract The latest comparative studies of climate policies reinforce the fundamental importance of employing adaptation planning alongside national development strategies. While these studies are necessary to document and share the knowledge of the practices and experiences undertaken at the national level, documents are still scarce on regions of ...

Impaired cell growth under ammonium stress explained by modeling the energy cost of vacuole expansion in tomato leaves

The Plant Journal, Volume 112, Issue 4, Page 1014-1028, November 2022., 2022
SUMMARY Ammonium (NH4+)‐based fertilization efficiently mitigates the adverse effects of nitrogen fertilization on the environment. However, high concentrations of soil NH4+ provoke growth inhibition, partly caused by the reduction of cell enlargement and associated with modifications of cell composition, such as an increase of sugars and a decrease in
