Solid State Polymerization on Poly(Lactic Acid)‐Based Microcapsules: Process Parameters Adjustment in Order to Design Coumarin‐6 Encapsulation System

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 42, November 10, 2025.
This work emphasizes solid state polymerization (SSP) as a modification tool for altering the properties of PLA microcapsules (MCs). Therefore, the SSP process is optimized in order to avoid particle aggregation, and its kinetics is studied. Also, loaded MCs are subjected to SSP, resulting in changing release rate.

V.F. Gening and Russian archaeological sites in the Vyatka river region

open access: yesПоволжская археология, 2014
The article is devoted to V. F. Gening’s contribution to the study of Russian archaeological sites of the Vyatka region. In 1949, he examined the Iskor fortified settlement site – one of the first ancient Russian settlements of the region. Starting 1954,

Spirals in protoplanetary disks from photon travel time [PDF]

open access: yes, 2016
Spiral structures are a common feature in scattered-light images of protoplanetary disks, and of great interest as possible tracers of the presence of planets.

Multimodal Pharmacological Assessment of Arenga porphyrocarpa Palm Leaves and Stems Extracts: Insights From In Vivo, In Vitro, and In Silico Approaches

open access: yesFood Science &Nutrition, Volume 13, Issue 11, November 2025.
Arenga porphyrocarpa leaf and stem extracts demonstrated significant neuropharmacological, antioxidant, and thrombolytic potentials. GC–MS profiling identified 51 bioactive constituents, while molecular docking revealed strong affinities toward key biological targets underlying these pharmacological effects.

Multiple paths of deuterium fractionation in protoplanetary disks

open access: yes, 2018
We investigate deuterium chemistry coupled with the nuclear spin-state chemistry of H$_2$ and H$_3^+$ in protoplanetary disks. Multiple paths of deuterium fractionation are found; exchange reactions with D atoms, such as HCO$^+$ + D, are effective in ...

Consortium of Lettuce and Beet in Succession to Green Manure Irrigated by Treated Dairy Effluent

open access: yesWater Environment Research, Volume 97, Issue 11, November 2025.
The objective of this study was to evaluate the production of lettuce cultivated in conjunction with table beet following the irrigation of green manure with treated effluent from a dairy processing plant and its impact on the chemical characteristics of the soil.

Revisiting the pre-main-sequence evolution of stars II. Consequences of planet formation on stellar surface composition

open access: yes, 2018
We want to investigate how planet formation is imprinted on stellar surface composition using up-to-date stellar evolution models. We simulate the evolution of pre-main-sequence stars as a function of the efficiency of heat injection during accretion ...

An Improved Physical Model for Open Channel Confluences: Bridging the Gap Between Laboratory and Field Observations

open access: yesWater Resources Research, Volume 61, Issue 10, October 2025.
Abstract Despite decades of research on hydro‐morphodynamic processes at open‐channel confluences, significant discrepancies persist between flume experiments and field observations. This study investigated the underlying causes by compiling and comparing geometric and hydraulic parameters from both natural confluences and laboratory setups.

The inner regions of protoplanetary disks

open access: yes, 2010
To understand how planetary systems form in the dusty disks around pre-main-sequence stars a detailed knowledge of the structure and evolution of these disks is required. While this is reasonably well understood for the regions of the disk beyond about 1

Tantric religion and social change

open access: yesThe Australian Journal of Anthropology, Volume 36, Issue 2, Page 268-279, August 2025.
Abstract During the period between the seventh and 11th centuries, several religious innovations occurred in Indic religions (which I refer to anachronistically as ‘Hinduism’). In particular, during this period, we see the rise of tantric traditions based on a new revelation of texts, some of whose followers regarded themselves as transcending the ...
