Nerve commitment in Hydra. I. Role of morphogenetic signals [PDF]

open access: yes, 1981
The kinetics of nerve commitment during head regeneration in Hydra were investigated using a newly developed assay for committed cells. Committed nerve precursors were assayed by their ability to continue nerve differentiation following explanation of ...

Navigating the Rapids: How Non‐Governmental Organization Managers Develop Strategic Adaptation to Repressive Political Environments

open access: yesPublic Administration and Development, EarlyView.
ABSTRACT This article explores the management adaptation strategies non‐governmental organizations (NGOs) managers employ in order to operate in repressive political environments. It answers the question: how do NGO managers initiate, manage and sustain internal change when the political/regulatory environment changes?

A Hybrid Solid‐State Battery with a Panoramic‐Scale Stack of Bulk Electrodes and a Thin‐Film Electrolyte

open access: yesSmall, EarlyView.
A hybrid all‐solid‐state battery (ASSB) is implemented by integrating a thin‐film electrolyte on a bulk anode, and a thick cathode sheet. A densified anode substrate with suppressed porosity is prepared by cold pressing. Thin‐film electrolyte is fabricated onto the bulk substrate via co‐sputtering and infrared‐based rapid annealing.

Cabomba caroliniana and Schoenoplectus californicus as Antifouling Candidates: Anti‐Attachment and Toxicological Effects in Aurelia coerulea (Cnidaria, Scyphozoa)

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Biofouling on artificial surfaces in aquatic ecosystems leads to significant economic losses. Current antifouling paints, while effective, often harm the aquatic environment. This study explores ecologically safe antifouling alternatives derived from plants, focusing on the aquatic macrophytes Cabomba caroliniana (CC) and Schoenoplectus ...

Critical point drying of brain tissue for X‐ray phase‐contrast imaging

open access: yesJournal of Synchrotron Radiation, EarlyView.
X‐ray phase contrast tomography can efficiently image brain tissue at subcellular resolution. Critical point drying allows a gentle replacement of interstitial material by air, enhancing X‐ray phase contrast of the ultrastructural features.X‐ray phase‐contrast tomography can efficiently image brain tissue at subcellular resolution.

On the Physical Characteristics of the Hydra Cluster of Nebulae [PDF]

open access: yes, 1942
A. Observational Data. - In a previous paper [1] counts of the brighter nebulae in the Hydra cluster were communicated. The distance of the Hydra cluster was estimated as 7.3 X 10^6 parsecs and the average apparent velocity of recession to be expected ...

Quantitative analysis of cell types during growth and morphogenesis in Hydra [PDF]

open access: yes, 1973
Tissue maceration was used to determine the absolute number and the distribution of cell types in Hydra. It was shown that the total number of cells per animal as well as the distribution of cells vary depending on temperature, feeding conditions, and ...

A ‘Wholly Unjustifiable Treatment of British Subject’? The Detention of W. T. Goode in the Baltic, 1919

open access: yesHistory, EarlyView.
Abstract In the summer of 1919, W. T. Goode, the Manchester Guardian’s special correspondent in Russia and the Baltic, was arrested in the Estonian capital Tallinn and briefly detained aboard a British warship. Goode's detention caused a furore, leading to accusations of kidnap, heated commentary in the press and questions in parliament.

Methane seep in shallow-water permeable sediment harbors high diversity of anaerobic methanotrophic communities, Elba, Italy

open access: yesFrontiers in Microbiology, 2016
The anaerobic oxidation of methane (AOM) is a key biogeochemical process regulating methane emission from marine sediments into the hydrosphere. AOM is largely mediated by consortia of anaerobic methanotrophic archaea (ANME) and sulfate-reducing bacteria
