Optimization and sustainability analysis of PV/wind/diesel hybrid energy system for decentralized energy generation

open access: yesEnergy Strategy Reviews, 2020
This paper focuses on the techno-economic feasibility and sustainability of a PV/wind/diesel hybrid system designed for decentralized power supply. Several designs have been studied for the hybrid system by varying the PV slope and wind turbine hub ...

Considering the Risks and Costs of Solid Organ Xenotransplantation

open access: yesAdvanced Biology, EarlyView.
This perspective discusses the rationale, risks, and costs of whole‐organ xenotransplantation. It considers alternative strategies to obviate the demand for transplants and optimize allotransplantation systems and practices that do not impose xenotransplantation's harms and risks, and whether they are the most ethical and effective means to increase ...

Temporal changes in avian abundance in aspen-dominated boreal mixedwood forests of central Saskatchewan, Canada

open access: yesAvian Conservation and Ecology, 2018
The boreal forest provides important breeding habitat for many migratory songbirds; however, changes in disturbance regimes have led to concern for populations breeding there. Monitoring data to track changes in boreal forest bird populations are scarce.

Environmental Impact Assessment of Copper‐Alloy Production Using Process Simulation and Semantic Modeling

open access: yesAdvanced Engineering Materials, EarlyView.
In the current research, how environmental impacts of products can be tracked through complex production networks using semantic data and environmental impact calculations is demonstrated. Here, the example of secondary copper production and the subsequent production of copper alloys is discussed.

Measurement and verification analysis on the energy performance of a retrofit residential building after energy efficiency measures using RETScreen Expert

open access: yesAlexandria Engineering Journal, 2020
Korean old residential apartments built over many decades were constructed without proper energy efficiency measures. This makes the energy performance of existing buildings to be very poor when compared with the energy performance of new buildings. This

Climate Monitoring using Internet of X-Things [PDF]

open access: yesarXiv, 2020
Global climate change is significantly affecting the life on planet Earth. Predicting timely changes in the climate is a big challenge and requires great attention from the scientific community. Research now suggests that using the internet of X-things (X-IoT) helps in monitoring global climate change.

A new framework for climate sensitivity and prediction: a modelling perspective [PDF]

open access: yes, 2014
The sensitivity of climate models to increasing CO2 concentration and the climate response at decadal time scales are still major factors of uncertainty for the assessment of the long and short term effects of anthropogenic climate change. While the relative slow progress on these issues is partly due to the inherent inaccuracies of numerical climate ...
