Investigation of the Reoxidation and Material Behavior of Directly Reduced Pellets and Fines Under Simulated Rail Transport Conditions

open access: yessteel research international, EarlyView.
The study investigates the reoxidation behavior of DRI pellets (Midrex and H2‐reduced) under realistic conditions, considering the test parameters of temperature, humidity, storage duration, particle size (including fine fraction), and container geometry. The samples are analyzed based on mass changes.

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

open access: yesStructural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

Marginal costs for railway level crossings in Sweden

open access: yes, 2019
The purpose of the present study is to estimate accident risks and marginal costs for railway level crossings in Sweden. The marginal effect of train traffic on the accident risk is used to derive the marginal cost per train passage that is due to level crossing accidents.

Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.

Adaptation of road safety inspection method to railway level crossings

open access: yes
In recent years, the number of road traffic crashes showed a decreasing trend in Hungary, but this cannot be stated about crashes at road-railway level crossings.

Stepwise Pre‐Treatment Enables Tunable Phase Evolution for High‐Efficiency Co‐Evaporated and Sulfurized Cu2ZnSnS4 Solar Cells

open access: yesSusMat, EarlyView.
A stepwise pre‐treatment strategy combining pre‐alloying and pre‐sulfurization regulates the phase‐evolution kinetics of co‐evaporated CZTS absorbers. The engineered intermediate phases promote direct kesterite crystallization, suppress defects and nonradiative recombination, and deliver a power conversion efficiency of 10.62%, representing the highest

Programmable Logic Controllers for Systems of Automatic of the Level Crossing

open access: yesAdvances in Electrical and Electronic Engineering, 2006
The railway crossings are vulnerable to incidence of high number of accidents often deadly. In order to face this problem, the modern systems of automatic of the level crossing have been introduced.

Ungulate substrate use in fauna passages

open access: yesWildlife Biology, EarlyView.
Fauna passages are increasingly constructed at major roads and railways to mitigate the negative effects of infrastructure and traffic on wildlife. The function of such passages depends on design, including the construction materials, soil, and vegetation.

Evaluation of Safety Improvement in Iranian Railway Level Crossings

open access: yes, 2020
Increasing railway level crossing accidents during nineties, made the railway to analyse the situation. The primary investigation showed that; despite having very few level crossings, unfortunately, the number of accidents is 4 times greater than the ...

Effects of complex soundscapes on the occurrence of Anaxipha pallidula in isolated green spaces in Tokyo

open access: yesWildlife Biology, EarlyView.
Urban green spaces experience a mix of natural and anthropogenic noises, which could disrupt the vocal communication of several species. This study investigated how such complex soundscapes affect the occurrence of Anaxipha pallidula, which communicates through calls, focusing on both sound level and quality.
