Out-of-plane dynamic response of a tuff masonry wall. Shaking table testing and numerical simulation [PDF]

open access: yes, 2017
The out-of-plane dynamic response of a masonry element is investigated, both experimentally and numerically. The results of shaking table tests on a tuff masonry wall, subjected to harmonic acceleration histories, are presented.

Bioprospecting Ulleungdo‐isolated microalgae for carbon valorization and utilization

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The growing demand for renewable energy alternatives has intensified global interest in microalgae as versatile bioresources for carbon valorization and bioenergy production. Owing to their rapid growth and biochemical versatility, microalgae provide a sustainable route for converting captured carbon into bioenergy and high‐value products ...

Miocene Slănic Tuff, Eastern Carpathians, Romania, in the Context of Badenian Salinity Crisis

open access: yesGeosciences, 2018
New geochronological investigations for the Slănic Formation, correlated with previous bio- and lithostratigaphical information, allow for a better succession of events for the Middle Miocene, including the absolute age of the Badenian salinity crisis in

Diffusion of Carbamazepine in Hydrophobic Zeolites: A Comparative Study Using Classical and Machine‐Learned Potentials

open access: yesChemistry – A European Journal, EarlyView.
Can hydrophobic, shape‐selective zeolites efficiently remove the persistent pharmaceutical CBZ from water? This work moves beyond the static picture of interaction energies by modeling diffusion with umbrella sampling and machine‐learned potentials. Even high intrinsic diffusion barriers can be overcome through exergonic adsorption from water, yielding

Paleoenvironmental analysis of the Mangere Formation, Mangere Island, Chatham Islands, New Zealand : a thesis submitted in Earth Science for the degree of Master of Science at Massey University [PDF]

open access: yes, 2006
Mangere Island consists almost entirely of alkali basalt of the late Miocene early Pliocene Rangiauria Formation (Campbell et al., 1993) with outcrops of the sedimentary Tupuangi Formation on the east coast and the Mangere Formation (Campbell, et al ...

Probability prediction of true‐triaxial compressive strength of intact rocks based on the improved PSO‐RVM model

open access: yesDeep Underground Science and Engineering, EarlyView.
In this work, we propose an improved particle swarm optimization (PSO) algorithm and develop an improved PSO‐relevance vector machine (RVM) model as a substitute for traditional true‐triaxial testing. The model's high prediction accuracy was validated through comparisons with two other machine learning methods and five three‐dimensional Hoek–Brown type

Radiation protection considerations on radon and building materials radioactivity in Near Zero Energy Buildings [PDF]

open access: yes, 2017
Recent updates of the E.U. Basic Safety Standards, stated in the Council Directive 2013/59/EURATOM, are focusing on risks related to radon gas concentration inside dwellings and working places, as well as radioactivity of building materials.
