Sustainable Living Unveiled: A Comprehensive Review of Key Studies on Zero Energy Homes
Published: 2023-12-20
Subjects: Engineering, Life Sciences
The journey to achieve Net Zero Energy in residential areas has progressed slowly. However, in recent times, the research behind accessing Net Zero has become more consistent. This paper discusses the steps to be taken in terms of technology, energy consumption, and energy efficiency to reach the goal of Net Zero. The timeline has been changed throughout discovering new and improved ways to [...]
Shortening and extrusion in the East Anatolian Plateau: how was Neogene Arabia-Europe convergence tectonically accommodated?
Published: 2023-12-20
Subjects: Physical Sciences and Mathematics
Deformation in orogenic belts is typically widely distributed but may be localized to form discrete, fast-moving fault zones enclosing semi-rigid microplates. An example is the Anatolian microplate, which is extruding westwards from the East Anatolian Plateau in the Arabia-Eurasia collision zone along the North and East Anatolian Faults that cause devastating earthquakes, including the February [...]
Zero Energy Homes: Definitions, Design Considerations, Challenges, and Real-world Applications
Published: 2023-12-20
Subjects: Engineering, Life Sciences
In the pursuit of sustainable living, Zero Energy Homes (ZEHs) have emerged as a promising solution to mitigate the carbon footprint of residential housing. This review paper explores the multifaceted realm of ZEHs by examining diverse definitions, design considerations, challenges, and real-world applications. The lack of standardized definitions is addressed, encompassing variations from [...]
Comprehensive Analysis of Riverine Flood Impact on Bridges: Iowa Case Study
Published: 2023-12-20
Subjects: Environmental Engineering
Floods often have a catastrophic impact on human life in terms of economic loss, infrastructure damage, and loss of life. Transportation network resilience is one of the critical aspects of supply lines for delivering goods and services during and after disaster events. Understanding vulnerable transportation segments is critical to addressing potential disruptions that may be caused by a flood [...]
Field testing autogenic storage thresholds for environmental signals in the strata of the Mississippi River Delta, U.S.A.
Published: 2023-12-19
Subjects: Physical Sciences and Mathematics
Sediments transported from source terrains to depositional sinks carry environmental signals, which may or may not be preserved in stratigraphy. Recently developed theory suggests storage thresholds for environmental signals are set by the internal dynamics of sediment transport systems. For the first time, we explore this theory by testing whether changes in relative sea level (RSL) of various [...]
Role of Indonesian Archipelago on Global Thermohaline Circulation: Insights from Numerical Experiments
Published: 2023-12-18
Subjects: Numerical Analysis and Scientific Computing, Oceanography, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics
This study employs the cGENIE Earth System Model to investigate the effects of the Indonesian Throughflow (ITF) and Indonesian Archipelago (IA) closure on global meridional thermohaline circulation (THC). Over a simulated period of 10,000 years, the analysis centers on critical variables, including surface density, vertical density profiles, global overturning circulation, and ocean ventilation [...]
A Hybrid Pore-Network-Continuum Modeling Framework for Flow and Transport in 3D Digital Images of Porous Media
Published: 2023-12-18
Subjects: Civil and Environmental Engineering, Oil, Gas, and Energy
Understanding flow and transport in multiscale porous media is challenging due to the presence of a wide range of pore sizes. Recent imaging advances offer high-resolution characterization of the multiscale pore structures. However, simulating flow and transport in 3D digital images requires models to represent both the resolved and sub-resolution pore structures. Here, we develop a hybrid [...]
On the economic feasibility of tidal range power plants
Published: 2023-12-17
Subjects: Civil and Environmental Engineering, Computational Engineering, Engineering, Environmental Engineering, Hydraulic Engineering
The wave potential energy associated with tides presents a promising sustainable energy resource. Uncertainties on the economic case of tidal range power plants are a known bottleneck hindering the development of the industry. Significant costs depend on each design's general arrangement, which includes both mechanical components and the associated civil works. Research on tidal range structures [...]
Assessing recent thaw and subsidence of peatland permafrost in coastal Labrador, northeastern Canada
Published: 2023-12-16
Subjects: Physical Sciences and Mathematics
Ground temperatures have been monitored since 2014 in four shallow boreholes (up to 5.7 m deep) drilled in palsas along the southeastern Labrador Sea coastline. This borehole network is critical for monitoring the effects of climate change on the terrestrial cryosphere and includes some of the southernmost coastal permafrost in the Northern Hemisphere. In this region, there are very few published [...]
Untangling intercropping in heterogeneous smallholder maize-cassava farming systems with remote sensing
Published: 2023-12-14
Subjects: Environmental Monitoring, Environmental Sciences, Physical Sciences and Mathematics
Earth observation approaches for large-scale crop monocultures are often not transferable to heterogeneous smallholder systems. Key challenges in this regard are intercropping, high intra-field crop type variability, wide sowing windows, presence of non-crop vegetation and small but variable field sizes. Currently, studies on smallholder agriculture mainly focus on specific crops and seldom [...]

Amplified seasonality in western Europe in a warmer world
Published: 2023-12-10
Subjects: Physical Sciences and Mathematics
Documenting the seasonal temperature cycle constitutes an essential step towards mitigating risks associated with extreme weather events in a future warmer world. The mid-Piacenzian Warm Period (mPWP), 3.3 – 3.0 million years ago, featured global temperatures approximately 3°C above pre-industrial levels. It represents an ideal period for directed paleoclimate reconstructions equivalent to model [...]
Sensitivity Analysis of Global Kinematics on Mantle Structure Using Automatically Generated Adjoint Thermochemical Convection Codes
Published: 2023-12-10
Subjects: Earth Sciences, Geophysics and Seismology, Numerical Analysis and Scientific Computing, Tectonics and Structure
Within the past 30 years, numerical models of mantle convection have been able to predict observations on Earth and planets, and among them tectonics. The possibility of building inverse problems in global geodynamics became concrete, and often involve the development of adjoint codes. Such tools provide efficient ways to estimate sensitivities of misfit functions relative to control parameters, [...]
