NATURA 2000 IN ROMANIA - A DECADE OF GOVERNANCE CHALLENGES

European Journal of Geography, 2017
Prior to Romania’s joining the European Union in 2007, the Romanian government assumed the responsibility to fully implement Community legislation in the field of nature conservation. This led to a rapid increase of protected surface areas (from 7% in

Calcium supplementation of breeding birds: directions for future research [PDF]

Ibis, 2004
Calcium is an essential nutrient for avian reproduction. Calcium‐rich foods are consumed by breeding birds for production of eggshells and for provisioning chicks that are mineralizing skeletal tissues. A number of studies have documented calcium‐limited reproduction, and calcium supplementation has been employed over the last decade to demonstrate ...

Heteroatom‐Engineering Promoted Co9S8 Bi‐functional Electrocatalyst for Hydrazine‐Assisted Hydrogen Production at Industrial Current Density

Advanced Functional Materials, EarlyView.
Fe and P co‐doped Co9S8 nanocorals (Fe, P‐Co9S8) are successfully synthesized by a heteroatom engineering strategy, which exhibit outstanding bifunctional electrocatalytic performance for both the hydrogen evolution reaction (HER) and hydrazine oxidation reaction (HzOR).

Head-direction coding in the hippocampal formation of birds [PDF]

, 2020
AbstractBirds strongly rely on spatial memory and navigation. Therefore, it is of utmost interest to reveal how space is represented in the avian brain. Here we used tetrodes to record neurons from the hippocampal formation of Japanese quails – a ground-dwelling species – while the quails roamed a 1×1-meter arena (>2,100 neurons from 23 birds ...

Nanolayer‐Encapsulated Stretchable Liquid‐Metal Sheets for Thermal Management

Advanced Functional Materials, EarlyView.
A stretchable liquid metal sheet with both high thermal conductivity and mechanical flexibility is developed. Its trilayer structure, comprising copper‐particle‐dispersed gallium liquid metal encapsulated by styrene‐butadiene‐styrene nanosheets, shows 40.4 W m−1 K−1 conductivity, elongation exceeding 200%, and retention of 96% of its initial ...
