Enhanced heat dissipation of truncated multi-level fin heat sink (MLFHS) in case of natural convection for photovoltaic cooling

open access: yesCase Studies in Thermal Engineering, 2021
The increase in module operating temperature above 25 °C can be detrimental to the electrical output performance of photovoltaic (PV) modules. The study introduces a novel truncated multi-level fin heat sink (MLFHS) subject to natural convection for ...

Thermal Analysis of Vertical Plate Fin Heat Sink [PDF]

open access: yesE3S Web of Conferences, 2020
Heat Sinks are widely used to remove the heat from the components which are generating heat during their functioning. Overheating causes malfunctioning of the components as well as it is responsible for reducing their life. Free convection is very common

Nutrient dynamics and development of soil fauna in vegetated roofs with the focus on biochar amendment

open access: yesNature-Based Solutions, 2021
The impacts of biochar amendment on the quality and quantity of runoff, substrate properties and soil fauna in two types of experimental vegetated roofs (‘plantings’ and ‘mats’) were examined during a 7-year period in southern Finland.

Faecal Glucocorticoid Metabolites and H/L Ratio Are Related Markers of Stress in Semi-Captive Asian Timber Elephants

open access: yesAnimals, 2020
Animals are kept in captivity for various reasons, but species with a slower pace of life may adapt to captive environments less easily, leading to welfare concerns and the need to assess stress reliably in order to develop effective interventions.
