Price induced water irrigation: Unraveling conflicts and synergies between European agricultural and water policies [PDF]

The 2003 CAP reform considerably affects cropping patterns in European agriculture. At the same time the imperatives of the forthcoming Water Framework Directive (WFD) is expected to modify irrigation decisions especially in Southern Europe where ...

The Water Framework Directive could be the Key

Ökologisches Wirtschaften - Fachzeitschrift, 2003
Die Wasserrahmenrichtlinie ist eine der wichtigsten neuen EU-Richtlinien im Hin­blick auf eine nachhaltige Entwicklung. Auch in den Beitrittsländern sind die Vorbe­reitungen zur Übernahme in vollem Gange. Da das Management von Wasserres­sourcen in unmittelbarem Zusammenhang mit Fragen der Landnutzung und der all­gemeinen wirtschaftlichen Entwicklung ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

C2α‐carbanion‐protonating glutamate discloses tradeoffs between substrate accommodation and reaction rate in actinobacterial 2‐hydroxyacyl‐CoA lyase

FEBS Open Bio, EarlyView.
Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Sources of uncertainty in DNA metabarcoding of whole communities: Implications for its use in biomonitoring

Methods in Ecology and Evolution
Advancements have been made in the use of DNA‐based methods for the detection of single species. However, the routine application of DNA‐based methods to monitor whole communities using a metabarcoding approach and derive ecosystem status continues to be

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Potential groundwater and surface water contamination from nitrate in the Po River Delta (Northern Italy): results from an applied research within the Water Framework Directive

, 2009
Nitrogen losses from agricultural sources have been recognised as one of the most serious threats in industrialised and emerging countries, determining ecosystem eutrophication and groundwater nitrate contamination.

Promiscuous stimulation of HSP70 ATPase activity by parasite‐derived J‐domains

FEBS Open Bio, EarlyView.
The malaria parasite Plasmodium falciparum exports three highly homologous yet functionally divergent J‐domain proteins into human erythrocytes. Here, we show that J‐domains isolated from all three proteins effectively stimulate the ATPase activity of both endogenous host and exported parasite HSP70 chaperones.

Salt marshes in the water Framework Directive

, 2005
The Water Framework Directive requires the description of reference conditions and good ecological statuses of several ecological parameters and multimetrics for assessment. One of these parameters is 'salt marshes'. Due to many changes (embankments in particular) within the water bodies no directly applicable reference conditions can be developed for ...
