Finite element modelling of cracking behaviour of reinforced concrete tensile members using a phase field approach
Modelling the cracking behaviour of reinforced concrete (RC) elements remains a major challenge due to the inherent heterogeneity of concrete and the complex interaction with steel reinforcement. Existing finite element ...
Fatigue behavior of externally bonded and hybrid-bonded carbon fiber reinforced polymer–to–concrete joints
Although the bond behavior and failure modes of externally bonded reinforcement (EBR) fiber-reinforced polymer (FRP) and hybrid-bonded (HB) systems on concrete have been widely investigated under quasi-static loading, their ...
Heat flux through a geothermally heated fluidized bed at the bottom of a lake
Heat fluxes and the underground inflow through a natural fluidized bed within the main sub-basin of Lake Banyoles are studied and parameterized. In the upper part of this fluidized bed, at a depth of about 30 m, the vertical ...
Probability Distribution of Turbulent Kinetic Energy Dissipation Rate in Ocean: Observations and Approximations
The probability distribution of turbulent kinetic energy dissipation rate in stratified ocean usually deviates from the classic lognormal distribution that has been formulated for and often observed in homogeneous layers ...
Infiltration of Microfibers in Sediment Beds in Moderate- to High-Turbulent Aquatic Environments
Sediment beds of aquatic ecosystems are known to present high microplastic contamination levels, where the infiltration of microplastic particles can extend deep into the sediment. In particular, turbulence can fuel the ...
Tendencies in the Tempo of Prehistoric Agricultural Expansions
This paper reviews the data and some models of premodern farming expansions. Comparison of archaeological data and models makes it possible to estimate the relative importance of demic and cultural diffusion, as well as ...
Holistic assessment of chemical and biological pollutants in a Mediterranean wastewater effluent-dominated stream: Interactions and ecological impacts
The discharge of treated wastewater from wastewater treatment plants (WWTPs) into river systems is a significant source of pollution, introducing a range of chemical and biological pollutants that impact the chemical and ...
Aquatic deoxygenation associated with resuspension of anthropogenic organic matter
Aquatic environments are highly polluted due to the anthropogenic pressures associated with large populations. Among these ecosystems, coastal lagoons are particularly sensitive to anthropogenic disturbances. The Mar Menor ...

Exploring the Tiny World of Microplastics in Your Own “Lab”
Microplastics are tiny pieces of plastic that result from the breakdown of larger plastic objects, such as water bottles, shopping bags, food containers, and many other types of waste. Microplastics can be as small as a ...
Settling velocities of microplastics with different shapes in sediment-water mixtures
The widespread distribution of microplastics (MP) in aquatic systems highlights the need for a clear understanding of how they are transported and accumulate on the bottom of water bodies. Developing predictive models for ...
Global Assessment of the Cloud-Aerosol Transition Zone Using CALIPSO
The interactions between clouds and aerosols represent one of the largest uncertainties in assessing the Earth’s radiation budget, highlighting the importance of research on the transition zone (TZ) within the cloud-aerosol ...
Analytical prediction of the thermal overheating in curing thick layers of fibre-reinforced thermosets
A recurring problem when curing thick specimen carbon-fibre-reinforced polymers is the formation of thermal gradients. Thermal gradients can lead to heterogeneous properties, overcuring and, in some cases, matrix degradation. ...
Polymerization kinetics of a recyclable thermoplastic as a matrix for structural composites
In this contribution we have performed the kinetic analysis of the curing process and of its thermal decomposition. Due to the presence of a peroxide initiator, polymerization is a complex process involving an induction ...
Effects of Processing Conditions of a Ball-Milled Fe65Co35 Soft Ferromagnetic Alloy on the Structural, Thermal, and Magnetic Properties
The Fe65Co35 alloy is a well-known Fe-based soft ferromagnetic alloy with excellent soft magnetic properties, which make it a strong candidate to be used in technological applications. In the present work, synthesizing ...
Collaborative learning, cooperative learning and reflective learning to foster sustainable development: A scoping review
Education for Sustainable Development (ESD) plays a key role in addressing global challenges. This study highlights the key role of collaborative, cooperative and reflective learning in enhancing students' ability to promote ...
Mechanosynthesis of Nanocrystalline Biphasic Ni-Fe Alloy Powders by Mechanical Alloying and Their Structural and Thermal Characterization
An equiatomic Ni-Fe alloy was synthesized through mechanosynthesis, under an argon atmosphere using a planetary ball mill, after 100 h. To assess the phase stability, the alloy was subsequently annealed at 923.15 K for 2 ...
Characterization of the microstructural, magnetic, and thermal behaviors of boron-doped Fe-Co-Ni alloys produced via mechanical alloying
FeCoNi alloys, both doped and undoped, were synthesized into nanocrystalline forms using a high-energy mechanical milling technique. The study used the x-ray diffraction technique to examine the microstructure characteristics ...
A method to assess the cloud-aerosol transition zone from ceilometer measurements
Cloud and aerosol contribution to the Earth's radiative budget constitutes one of the most significant uncertainties in future climate projections. To distinguish between clouds and cloud-free air, atmospheric scientists ...
GPS observables in Newtonian spacetime or why we do not need ‘physical’ coordinate systems
Some authors have defended the claim that one needs to be able to define ‘physical coordinate systems’ and ‘observables’ in order to make sense of general relativity. Moreover, in Rovelli (Physical Review D, 65(4), 044017 ...
