Improving the mechanical characteristics of environmentally friendly concrete using fly ash and brick powder as partial sand replacements [PDF]

Građevinski Materijali i Konstrukcije
Infrastructure and urbanization drive the demand for concrete, which puts pressure on natural resources and jeopardizes the ecosystem. Incorporating recycled materials into concrete can fulfill this demand without sacrificing quality. This study examines

PERFORMANCE PREDICTION OF CHAIN SAW MACHINES USING SCHMIDT HAMMER HARDNESS

Bilimsel Madencilik Dergisi, 2018
Schmidt hammer hardness (RL) provides a quick and inexpensive measure of surface hardness that is widely used for estimating the mechanical properties of rock material such as strength, sawability, cuttability and drillability. In this study, RL as predictors, which is thought to be a useful, simple and inexpensive test particularly for ...

Mother tongue instruction as a sticky object: The making of a register of denunciation

Journal of Linguistic Anthropology, Volume 36, Issue 1, May 2026.
Abstract This article examines the making of a political register to denounce mother tongue instruction (MTI) in Sweden. Nationally mandated since 1977, MTI is a state‐sponsored, curriculum‐stipulated subject for minority pupils of over 187 languages other than Swedish.

Dietary Specialisation Shapes Gut Bacterial Diversity in Dung Beetles: Insights From Coprophagy to Millipede Carnivory

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Dung beetles feed on various food sources that are rich in microbial life. Here, we describe how the diets of seven dung beetle species, specialising in coprophagy, necrophagy, detritophagy, fungivory and carnivory influence their gut bacterial structure and diversity.

Studi Evaluasi Pengaruh Variasi Mutu Beton Terhadap Kekuatan Struktur Beton Normal Menggunakan Metode Non-Destructive Test dan Destructive Test

Rekayasa Sipil, 2019
To make the examination of the strength of existing building structures easier, can be done by using the NDT methods. It is therefore a study related to the combination of NDT and DT methods to obtain better accuracy of the results.

Perspectives on Time and Personality: Philip G. Zimbardo (1934–2024) in Memoriam

Journal of Personality, Volume 94, Issue 2, Page 181-198, April 2026.
ABSTRACT The present paper aims to honor the memory of one of the most notable figures in psychological science over the past five decades, Philip G. Zimbardo, who sadly passed away in late 2024. To this end, we provide a multi‐perspective view on psychological time—a topic that deeply engaged Phil Zimbardo during the later stages of his prolific ...

Analysing Indirect Methods for Comparatively Determining the Compressive Strength of Materials with Various Properties [PDF]

E3S Web of Conferences
The properties and compressive strength of hardened concrete are examined by destructive and non-destructive testing methods. There was no direct relationship between non-destructive testing results for existing concrete structures.

Drilling Within the Critical Zone

Hydrological Processes, Volume 40, Issue 3, March 2026.
This review synthesises 30 years of critical zone drilling methodologies for studying subsurface weathering, water storage, and biogeochemical processes. We evaluate drilling techniques, sampling strategies, downhole logging, and long‐term monitoring approaches while addressing contamination control and core preservation challenges.
