Saprolegnia on roach (Leuciscus rutilus) and carp (Cyprinus carpio) [Translation from: Acta zool.pathol.Antverpiensia 43 107-123, 1976] [PDF]

open access: yes, 1979
There is, in nature, as well as in the aquarium, a parasitic disease known as 'mousse' and which attacks predominantly fish. It is caused by Phycomycete fungi, genus Saprolegnia.

6 hr tide seen in sporadic E layers

open access: yes, 2018
The GPS radio occultation technique is used to study sporadic E (Es) layer plasma irregularities of the Earth’s ionosphere on a global scale using COSMIC/FORMOSAT-3 satellite constellation GPS signal-to-noise ratio (SNR) profiles. The maximum deviation from the mean SNR is attributed to the height of the Es layer. Es are produced by ion convergence due

Circular Economy Pathways for Airport Climate Change Mitigation

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Airport operators face growing climate‐change pressures; the circular economy offers pathways to reduce impacts and recover resources. We examine how airport operators apply the circular economy in practice. We use an exploratory qualitative multicase design based on practitioner‐generated documents (e.g., press releases and sustainability ...

Morphology and dynamics of sporadic E layers observed by amateur radio

open access: yesEarth and Planetary Physics
The Es layer is a thin layer that concentrates metallic ions in the mesosphere and lower thermosphere (MLT) region. When it occurs, it can affect the performance of the Global Navigation Satellite System and high/very high frequency (HF/VHF) radio ...

A Decision‐Making Model for Implementing Green Technology in Sustainable Building Projects

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Green technology (GT) adoption is pivotal for reconciling environmental stewardship with economic viability in the built environment, particularly in resource‐constrained emerging economies. However, empirical evidence on how specific GT drivers actively mitigate adoption barriers remains scarce.

Flap perfusion of superficial split flap design for guided bone regeneration: A case report with ultrasonography

open access: yesClinical Advances in Periodontics, EarlyView.
Abstract Background Effective flap management is crucial for successful bone regeneration procedures. Traditional flap release has been performed by the deep split design; recently, the superficial split design revives for its proposed anatomical and biomechanical advantages.

Diurnal variations in characteristics of sporadic layer Eₛ over Irkutsk

open access: yesSolar-Terrestrial Physics
We have studied the morphological features of semidiurnal variations in the occurrence of the sporadic Es layer (PEs) and height of the layer (hEs), using data from the Irkutsk DPS-4 ionosonde (52.3° N, 104.3° E) for 2003–2021.

A Two-Stage Machine Learning Framework for Predicting Sporadic E Occurrence and Intensity

open access: yesUniverse
Sporadic E (Es) layers exhibit strong intermittency and highly skewed intensity distributions, exerting significant impacts on high-frequency communication and navigation systems and posing challenges for data-driven prediction. Conventional single-stage

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

open access: yesChemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.
