Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods
Structural Concrete, EarlyView.Abstract Over the past few decades, prestressing techniques have become essential in the construction of key structures, infrastructure, and bridges. The serviceability and safety of prestressed concrete (PC) elements are closely tied to the effectiveness of the prestressing process.

Ungulate substrate use in fauna passages
Wildlife 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.

High Voltage, EarlyView.ABSTRACT This study explores the breakdown characteristics and discharge modes in a parallel plate air dielectric barrier discharge system using repetitive nanosecond pulses, with pulse repetition frequencies (PRFs) from 0.1 to 100 kHz. It examines how pulse parameters—PRF, pulse number and gas pressure—affect the memory effect, leveraging current and ...

Annals of Applied Biology, EarlyView.We investigated the role of vision in host‐seeking behaviour by Philaenus spumarius, the main European vector of Xylella fastidiosa, through an integrated anatomical, optical, physiological, and behavioural study. Our data highlight that the spittlebug uses visual cues, including polarized light, which may aid in detecting the polarized reflections ...

Archaeometric Characterization of Submerged Sasanian Stucco From Ghaleh Guri, Western Iran
Archaeometry, EarlyView.ABSTRACT The Ghaleh Guri archaeological site, a late Sasanian site with a building complex dated to 591–628 ce, lies along an ancient road linking the western Zagros to Mesopotamia. Its architectural remains, adorned with stucco, faced annual river floods yet remained stable for centuries.

Facilitated Transport of Organic Contaminants in a High Concentration, Multicomponent Plume
Groundwater Monitoring &Remediation, EarlyView.Abstract A field experiment evaluated the transport of organic contaminants in a plume from hazardous waste disposal areas at the Rocky Mountain Arsenal. The plume contained many xenobiotic contaminants, with widely varying expected mobilities.

POLARIMETRY OF LONG-PERIOD FIBER GRATINGS
, 2014 "In this thesis, an overview of long-period fiber gratings, including theoretical background, fabrication techniques and their applications are presented to explain fiber gratings properties, behavior and the importance of their characterization.

Journal of Microscopy, EarlyView.Abstract X‐ray phase contrast imaging (XPCI), when implemented in micro‐computed tomography (micro‐CT) mode, offers high‐contrast 3D imaging of weakly‐attenuating material samples. In the so‐called single‐mask edge illumination approach, a mask with periodically spaced transmitting apertures is used to split the x‐ray beam into narrow beamlets; when ...
