Plant-derived compounds with progesterone receptor (PR)-related activity (phytoprogestins) have been proposed as potential alternatives to endogenous progesterone; however, their pharmacological equivalence and clinical applicability remain uncertain. This systematic review aimed...

Engineering antifouling UiO-66-NH₂ mixed matrix membranes for geothermal brine pretreatment: Fouling prediction, techno-economic analysis, and environmental assessment

This study develops polysulfone/UiO-66-NH₂ mixed-matrix membranes (MMMs) for silica removal from geothermal brine and evaluates their antifouling behavior, fouling mechanisms, techno-economic feasibility, and environmental implications. Incorporation of UiO-66-NH₂ improved membra...

Gypsum-calcium carbonate-gelatine composite graft for bone repair: Biocompatibility and histological assessment in a rat model

Background Gypsum (calcium sulphate dihydrate; POP) is a resorbable synthetic bone substitute with favourable biocompatibility; however, its rapid degradation limits clinical effectiveness. A modified composite incorporating calcium carbonate and gelatine hydrogel (POPHD) was dev...

The Bahuma traditions of the Dayak Kenyah tribe, Kutai Kartanegara: An ecolinguistics study

The Bahuma (traditional farming) practice among the Dayak Kenyah tribe is not merely an agricultural activity but an integral part of their identity and local wisdom, deeply embedded with ecological values. However, this tradition is at risk of extinction due to policies prohibit...

Solvent selection governs the performance of low-quality cat’s eye damar resin as a bio-based coating for biomass composite roof tiles

The growing demand for sustainable construction materials has increased interest in bio-based coatings from renewable resources. This study investigated the effect of solvent type on the performance of Cat’s Eye damar resin as a protective coating for sorghum bagasse composite ro...

Response surface optimization of KIT-6 mesoporous silica synthesis using sapindus rarak bio-template for dye removal and waste cooking oil pyrolysis

Hybrid-templated KIT-6 mesoporous silica was synthesized using Pluronic P123 and Sapindus rarak extract as dual templates. The synthesis was optimized using Response Surface Methodology (RSM) to evaluate the structural and textural properties. The effects of the P123/SRE ratio, n...

Critical Fatigue Factors Among Indonesian Seafarers: A Delphi Consensus Study

Seafarer fatigue is multifactorial and a leading contributor to maritime accidents, yet we identified no study establishing which fatigue factors matter most for the Indonesian fleet, and maritime prioritisation studies rarely report indices that allow their consensus to be audit...

Measurements of the production of W$$^{\pm }$$ and Z$$^0$$ bosons in pp collisions at $$\sqrt{s} = 13$$ TeV

Abstract Measurements of the production of the W $$^{\pm }$$ ± and Z $$^0$$ 0 bosons at midrapidity in pp collisions at $$\sqrt{s} = 13$$ s = 13 TeV with ALICE at the Large Hadron Collider (LHC) are presented. The W $$^{\pm }$$ ± and Z $$^0$$ 0 bosons are detected via their (di)e...
