AMM (ABANDONED METHANE MINE) TECHNIQUES APPLICABLE TO MINING OPERATIONS DURING THE CLOSING OF THE JIU VALLEY

(STEF92 Technology, 2026, Cornel Boanta, Doru Cioclea, Florin Radoi, Cristian Cioara)

Show more

In the midst of an energy crisis, coal remains essential to the energy mix of many countries. Over time, coal reserves inevitably deplete, and as a result, coal mining progresses, and mines are closed and abandoned. Abandoned mines continue to emit methane for many years after closure, yet their emissions remain uncontrolled and unmonitored in many coal-producing regions. Closed mines may offer a small but significant opportunity to exploit a clean energy resource, known as Abandoned Mine Methane (AMM), which can ...

The efficiency of zinc oxide nanoparticles (ZnO-NPs) in inhibiting Phytophthora spp. growth in both durian fruits and stems is demonstrated. The size of ZnO-NPs used was in range of 25-50 nm in diameter. Diseased durian sample were collected from a durian orchard located in southern of Thailand. The pathogen of diseased durian was isolated for subsequent morphological identification. Three distinct strains of Phytophthora spp. (designated as PHY41, PHY45, PHY49) were successfully isolated and were found in colonie...

GREEN CITIES AS BIODIVERSITY HUBS

(STEF92 Technology, 2024-12-15, Denis Vasiliev, Lennart Bornmalm, Rodney Stevens)

Show more

Global biodiversity decline is dramatic. Urbanization is a global trend that is often driving biodiversity loss. At the same time urban green spaces can maintain high levels of biodiversity. However, for urban Nature-based Solutions to maintain biodiversity they have to be designed and managed with this goal in mind. Furthermore, there are certain risks to biodiversity associated with the urban green infrastructure. These risks merit consideration when urban planning is undertaken. Approaches to green infrastructu...

In contemporary agricultural practice, ensuring sufficient bioavailable macronutrients, particularly phosphorus, for plants in phosphorus-deficient soils remains a significant challenge. As a promising alternative, the application of phosphate-calcium-based nanofertilizers (NFs), with or without zinc, emerges as a suitable solution, offering targeted effects through foliar dispersion. However, current knowledge gaps persist regarding the development and colloidal properties of applied NFs and their impact on sunfl...

Approximately 5% of the area of Slovakia is made up of built-up areas and courtyards. These represent land where buildings and courtyards, motorways, roads, local roads, railways, airports, and water structures are built. To compare the influence of the urbanized part of the country on the daily air temperature, the city of Nitra, located in the western part of Slovakia, was selected. Meteorological stations are in the territory of the city, from which air temperature data were obtained. For the comparison of the ...

Urbanization is an ongoing trend. It causes various negative issues, including strain on human health and biodiversity. Cities are often subject to negative effects of climate change. Currently green and blue infrastructure are often seen as potential solutions for these problems. However, integration of topographically diverse sites and geological elements into urban landscapes is rarely considered as an important measure for addressing societal and environmental issues in cities. This can lead to lost opportunit...
