The territorial dimension of the Common Agricultural and Rural Development policy (CAP) and its relation to cohesion objectives
An increasing focus on rural development issues has characterised the discussion of Common Agricultural Policy (CAP) reform. This reflects new societal demands for tasks and services provided by agriculture particularly in mountain and less-favoured areas (LFA). The regional distribution of CAP and Rural Development support underpins the argument that the territorial dimension implied by CAP reforms has not yet been taken sufficiently into account. The regional variation in the distribution of the LFA scheme between member states testifies this imbalance and underscores country specific priorities. LFAs will have to prove that they are more than a compensation measure, but already providing a range of multifunctional tasks.territorial impact, rural development, less-favoured areas, LFA scheme, CAP reform
Unified model of hyperthermia via hysteresis heating in systems of interacting magnetic nanoparticles
We present a general study of frequency and magnetic field dependence of the
specific heat power produced during field-driven hysteresis cycles in magnetic
nanoparticles with relevance to hyperthermia applications in biomedicine.
Employing a kinetic Monte-Carlo method with natural time scales allows us to go
beyond the assumptions of small driving field amplitudes and negligible
inter-particle interactions, which are fundamental to applicability of the
standard approach based on linear response theory. The method captures the
superparamagnetic and fully hysteretic regimes and the transition between them.
Our results reveal unexpected dipolar interaction-induced enhancement or
suppression of the specific heat power, dependent on the intrinsic statistical
properties of particles, which cannot be accounted for by the standard theory.
Although the actual heating power is difficult to predict because of the
effects of interactions, optimum heating is in the transition region between
the superparamagnetic and fully hysteretic regimes

Frio brine sequestration pilot in the Texas Gulf Coast
A field experiment to pioneer CO2 injection for sequestration in a brine-bearing sandstone-shale sequence in the Texas Gulf Coast, USA, is in the preinjection modeling and planning phase. Innovations in this experiment include (1) CO2 injection into high-volume highpermeability rocks that have storage capacity sufficient to impact greenhouse gas emissions, (2) injection into a setting lacking the complications introduced by hydrocarbons and perturbations resulting from production and secondary recovery, and (3) intensive pre-, syn-, and post-injection monitoring and modeling for validation of the effectiveness of sequestration. The experiment is designed to provide a rapid increase in information from a small-volume and short-duration injection.Bureau of Economic Geolog

EOR as sequestration: Geoscience perspective
CO2 Enhanced Oil Recovery (EOR) has a development and operational history several decades longer than geologic sequestration of CO2 designed to benefit the atmosphere and provides much of the experience on which confidence in the newer technology is based. With modest increases in surveillance and accounting, future CO2 EOR using anthropogenic CO2 (CO2-A) captured to decrease atmospheric emissions can be used as part of a sequestration program.Bureau of Economic Geolog
