Improved construction of concrete viaducts with movable scaffolding systems in Spain [PDF]

open access: yes, 2016
The current paper relates the state of the art of construction of viaducts with a movable scaffolding system (MSS). Two different procedures are introduced: the traditional sequence and the new sequence applied to some viaducts in Spain.

Stronger Antipredatory Vigilance of Prey to Olfactory Cues From Injured Vulnerable Conspecifics

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
Eggs of spider mites are more vulnerable to predators. Reproductive females of spider mites are more vigilant to olfactory cues from injured eggs compared to that from injured adults and deutonymphs. ABSTRACT Predation risk is a key evolutionary force shaping prey behaviors and life‐history strategies across taxa. Predators often target vulnerable life

Strut-tie method of design and possible serviceability problems: an exploration by NLFE [PDF]

open access: yes, 2000
The strut and tie method presents a rational and consistent approach to the design of all parts in a reinforced concrete structure. With this approach, the load carrying mechanism of the structure is represented by approximating the compressive stress

Nanoparticle‐Based Tetracycline Delivery Systems: Advancing Therapeutic Effectiveness and Tackling Antibiotic Resistance

open access: yesParticle &Particle Systems Characterization, Volume 42, Issue 10, October 2025.
This review explores improved tetracycline (TCN) delivery via polymer‐based nanocarriers to enhance solubility, stability, and targeted release. It also covers stimuli‐responsive systems, triggered by pH, enzymes, or reactive oxygen species (ROS), and co‐delivery approaches that increase therapeutic efficacy in cancer and inflammatory diseases ...
