The EMSO Generic Instrument Module (EGIM): Standardized and Interoperable Instrumentation for Ocean Observation

open access: yesFrontiers in Marine Science, 2022
The oceans are a fundamental source for climate balance, sustainability of resources and life on Earth, therefore society has a strong and pressing interest in maintaining and, where possible, restoring the health of the marine ecosystems.

Sectional Analysis of Reinforced Engineered Cementitious Composite Columns Subjected to Combined Lateral Load and Axial Compression

open access: yesFrontiers in Materials, 2022
The ultra-high tensile ductility of ECC provides an alternative way to enhance the ductility of structural members by using high-ductile matrix material instead of simply increasing reinforcements. However, the application of ECC members is still limited

Influence of the specific load on stability and vibrations of the multimember column with internal cracks [PDF]

open access: yesBulletin of the Polish Academy of Sciences: Technical Sciences, 2023
Slender systems are mostly studied when Euler’s load or follower load is considered. The use of those types of external loads results in well-known divergence or flutter shape of the characteristic curve.

The effect of temperature and digested sewage sludge cover over tailings on the leaching of contaminants from Ballangen tailings deposit

open access: yesJournal of Water and Climate Change, 2021
Dry covers can be applied above tailings to reduce and prevent formation of acid mine drainage and leaching of contaminants. Efficiency of covers is affected by different parameters, of which temperature change under climate change context is one.

Pre-Load Effect on CFRP-Confinement of Concrete Columns: Experimental and Theoretical Study

open access: yesCrystals, 2021
The axial compression strength of concrete columns has been proved to be significantly enhanced by external confinement. In this perspective, the use of Fiber-Reinforced Polymers (FRPs) has been extensively studied.

“Latent Gastric Cancer” after Eradicating Helicobacter pylori

open access: yesGut and Liver, 2018
Background/AimsEndoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is useful for obtaining pancreatic mass samples. The combination of modified techniques (i.e., slow-pull technique and fanning technique) may improve the quality of the sample ...
