Shale gas - los yacimientos de hidrocarburos no convencionales: origen del Shale gas [PDF]

Epistemus, 2015
El shale gas tiene su origen en la acumulación de materia orgánica en cuencas marinas. En Norteamérica el gas de lutita (shale gas) es una fuente emergente de gas natural de bajo costo.

Flexible drought deciduousness in a neotropical understory herb. [PDF]

Am J Bot, 2022
Progression of leaf loss and growth between wet seasons. Abstract Premise Adaptive divergence across environmental gradients is a key driver of speciation. Precipitation seasonality gradients are common in the tropics, yet drought adaptation is nearly unexplored in neotropical understory herbs. Here, we examined two recently diverged neotropical spiral

Physicochemical and Thermal Evaluation of a Mixed-Mode Greenhouse Solar Dryer for Guava (Psidium guajava L.). [PDF]

J Food Sci
ABSTRACT The present study aimed to evaluate the quality and nutritional properties of guava slices dried in a greenhouse solar dryer (operated under mixed and direct modes) and an electric stove at 50°C. The results showed that mixed‐mode solar drying resulted in greater retention of vitamin C (112.60 mg/100 g), carotenoids (0.37 mg/g), and ...

Microbe-induced resistance involves priming of direct or indirect defenses according to the stage of herbivory. [PDF]

New Phytol
Summary Microbe‐induced resistance (MIR) encompasses a broad range of plant responses that mediate both direct and indirect defenses against herbivores. However, previous studies have addressed MIR in relation to either direct or indirect defenses in isolation, overlooking potential conflicts or synergies that may arise between MIR‐elicited defense ...

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.

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 ...

Bridging the ideological gap? How fairness perceptions mediate the effect of revenue recycling on public support for carbon taxes in the United States, Canada and Germany

Review of Policy Research, Volume 38, Issue 5, Page 529-554, September 2021., 2021
Abstract Carbon taxes are frequently advocated as a means of reducing greenhouse gas (GHG) emissions, yet their political feasibility remains a challenge. To enhance their political appeal, carbon tax proponents have proposed revenue recycling as a means of alleviating public concern with this instrument's visible costs.
