Gene Flow and Vertical Stratification of Pollination in the Bat‐Pollinated Liana Marcgravia longifolia

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
This study investigates pollen dispersal, vertical stratification of gene flow, and spatial genetic structure in the bat‐pollinated liana Marcgravia longifolia in a western Amazonian forest. Flowers are produced from the forest floor to the canopy, allowing analysis of pollination across strata.

EFFECT OF WELL STIMULATION ON THE SKIN FACTOR IN ELONGATED RESERVOIRS Efectos de la estimulación del pozo sobre el factor de daño en yacimientos alargados

open access: yesCT&F Ciencia, Tecnología & Futuro, 2006
Because of fluvial deposition or faulting, many reservoirs around the world may possess a long and narrow geometry in which linear flow is expected to take place once radial flow vanishes, if existed.

Putting Out Fires With Institutional Reforms: Experts as Policy Entrepreneurs in the Swedish Fire and Rescue Policy Sector, 1986–2021

open access: yesEuropean Policy Analysis, Volume 11, Issue 3, Page 420-432, Summer 2025.
ABSTRACT This article examines the fire and rescue services sector in Sweden in the period 1986–2021, and explains the timing of bureaucratic reforms using the Multiple Streams Framework (MSF). In this study, we insert institutions in MSF by employing a two‐level analysis; we highlight the interactions among experts acting as policy entrepreneurs over ...

Vitamin D deficiency induces erectile dysfunction: Role of superoxide and Slpi

open access: yesBritish Journal of Pharmacology, Volume 182, Issue 15, Page 3669-3687, August 2025.
Background and Purpose Epidemiological studies suggest a relationship between vitamin D deficiency and erectile dysfunction (ED). We hypothesized that vitamin D deficiency or vitamin D receptor (VDR) knockout causes ED and analysed the underlying molecular mechanisms.

The role of socialization network to understand the adoption of demand‐reduction behaviors: The red siskin's breeders community case study

open access: yesConservation Science and Practice, Volume 7, Issue 8, August 2025.
Social network analysis and decision‐making models revealed how socialization networks and psychosocial factors influence the adoption of sustainable bird‐sourcing practices among red siskin breeders across Venezuela, Brazil, Spain, and Portugal. Key findings, such as the role of information flow and attitudes towards collaboration, highlight the ...

The Computer‐Assisted Sequence Annotation (CASA) workflow for enzyme discovery

open access: yesApplications in Plant Sciences, Volume 13, Issue 4, July-August 2025.
Abstract Premise With the advent of inexpensive nucleic acid sequencing and automated annotation at the level of basic functionality, the central problem of enzyme discovery is no longer finding active sequences, it is determining which ones are suitable for further study.

CONVENTIONAL PRESSURE ANALYSIS FOR NATURALLY FRACTURED RESERVOIRS WITH TRANSITION PERIOD BEFORE AND AFTER THE RADIAL FLOW REGIME

open access: yesCT&F Ciencia, Tecnología & Futuro, 2009
It is expected for naturally occurring formations that the transition period of flow from fissures to matrix takes place during the radial flow regime. However, depending upon the value of the interporosity flow parameter, this transition period can show

Improving University Students' Learning of Programming Using Customised Pseudocode

open access: yesComputer Applications in Engineering Education, Volume 33, Issue 4, July 2025.
ABSTRACT Pseudocode is a well‐known tool for introducing students to the basics of programming. The aim of pseudocode is to make algorithmic constructs easy to write and to understand. In this study, we propose the design of a ‘natural’ pseudocode, with keywords frequently used in the mother tongue, referring to basic computational instructions and ...
