A discursive analysis of oppositional interpretations of the agro-food system: A case study of Latvia
2015
Abstract This article critically reflects on the literature that addresses the complexity of food systems, which is often caught in application of simplistic binary oppositions of local vs. global, short vs. long, sustainable vs. intensive, etc. It then goes on to show, through a case study analysis of food-system discourses in Latvia how the binary oppositions surrounding with food systems, are actually mobilised in a specific national context. Agro-food systems are often explained through binary opposing knowledge systems that, depending on the theoretical affiliation of the author, might be called frames, narratives or discourses. These powerful instruments are used to explain, and often…

Exponential Relaxation out of Nonequilibrium
1989
Simulation results are presented for a quench from a disordered state to a state below the coexistence curve. The model which we consider is the Ising model but with the dynamics governed by the Swendsen-Wang transition probabilities. We show that the resulting domain growth has an exponential instead of a power law behaviour and that the system is non-self-averaging while in nonequilibrium. The simulations were carried out on a parallel computer with up to 128 processors.

Gasification of pelletized renewable fuel for clean energy production
2011
Abstract The main aim of the study was to develop and investigate a small-scale experimental gasification technique for the effective thermal decomposition of pelletized renewable fuels (wood sawdust, wheat straw). The technical solution of the biomass gasifier for gasification of renewable fuels presents a downdraft gasifier with controllable additional heat energy supply to the biomass using the radial propane flame injection into the bottom part of the biomass layer. From the kinetic study of the mass conversion rate of pelletized biomass and variations of the composition of produced gas it is concluded that the process of biomass gasification is strongly influenced by the amount of addi…
