Internal Differentiation of the Archean Continental Crust: Fluid-Controlled Partial Melting of Granulites and TTG-Amphibolite Associations in Central…

2009

Fault bound blocks of granulite and enderbite occur within upper amphibolite-facies migmatitic tonalitic-trondhjemitic-granodioritic (TTG) gneisses of the Iisalmi block of Central Finland. These units record reworking and partial melting of different levels of the Archean crust during a major tectonothermal event at 2·6-2·7 Ga. Anhydrous mineral assemblages and tonalitic melts in the granulites formed as a result of hydrous phase breakdown melting reactions involving amphibole at peak metamorphic conditions of 8-11 kbar and 750-900°C. A nominally fluid-absent melting regime in the granulites is supported by the presence of carbonic fluid inclusions. The geochemical signature of light rare e…

Stochastic equation of population dynamics with diffusion on a domain

2003

We consider Lotka-Volterra competition model with diffusion in a territorial domain with a stochastic perturbation which represents the random variations of environment conditions. We prove the existence, the uniqueness and the positivity of the solution. Moreover, the stochastic boundedness of the solution is analized.

LA PROPAGACIÓN DE LA NULIDAD EN EL ÁMBITO DE LA INFRACCIÓN DEL DERECHO DE LA COMPETENCIA

2019

El presente artículo tiene por finalidad analizar la propagación de la nulidad por infracción del Derecho de la Competencia. Para ello, tras analizar el fundamento de la nulidad, el trabajo analiza cómo la propagación de la nulidad no es la solución correcta en todos los contratos conexos. En algunos supuestos la solución será la indemnización de daños y perjuicios por infracción del Derecho de la Competencia ejercitada por el perjudicado frente a la empresa infractora, aunque no tenga relación contractual directa con ella, pero no la nulidad.

The Perpetrator's mise-en-scene: Language, Body, and Memory in the Cambodian Genocide

2018

Rithy Panh's film S-21. The Khmer Rouge Killing Machine (2003) was the result of a three-year shooting period in the Khmer Rouge centre of torture where perpetrators and victims exchanged experiences and re-enacted scenes from the past under the gaze of the filmmaker's camera. Yet, a crucial testimony was missing in that puzzle: the voice of the prison's director, Kaing Guek Eav, comrade Duch. When the Extraordinary Chambers in the Courts of Cambodia (ECCC) were finally established in Phnom Penh to judge the master criminals of Democratic Kampuchea, the first to be indicted was this desk criminal. The film Duch, Master of the Forges of Hell (R. Panh, 2011) deploys a new confrontation – an a…

Life-Cycle Land-Use Requirement for PV in Vietnam

2021

Over the last 15 years, photovoltaics (PV) in Vietnam has experienced development. The increased installed capacity of PV requires more land for installation sites as well as for manufacturing the plants’ component and waste treatment during the plants’ decommissioning. As a developing country, in which more than 80% of the population’s livelihood depends on agriculture, there are concerns about the competition of land for agriculture and solar development. This paper estimates the life-cycle land-use requirement for PV development in Vietnam, to provide the scientific-based evidence for policy makers on the quantity of land required, so that the land budget can be suitably allocated. The d…

Numerical and Experimental Investigation of Equivalence Ratio (ER) and Feedstock Particle Size on Birchwood Gasification

2017

This paper discusses the characteristics of Birchwood gasification using the simulated results of a Computational Fluid Dynamics (CFD) model. The CFD model is developed and validated with the experimental results obtained with the fixed bed downdraft gasifier available at the University of Agder (UIA), Norway. In this work, several parameters are examined and given importance, such as producer gas yield, syngas composition, lower heating value (LHV), and cold gas efficiency (CGE) of the syngas. The behavior of the parameters mentioned above is examined by varying the biomass particle size. The diameters of the two biomass particles are 11.5 mm and 9.18 mm. All the parameters investigate wit…

Heuristic algorithms for a storage location assignment problem in a chaotic warehouse

2014

The extensive application of emerging technologies is revolutionizing warehouse management. These technologies facilitate working with complex and powerful warehouse management models in which products do not have assigned fixed locations (random storage). Random storage allows the utilization of the available space to be optimized. In this context, and motivated by a real problem, this article presents a model that looks for the optimal allocation of goods in order to maximize the storage space availability within the restrictions of the warehouse. For the proposed model a construction method, a local search algorithm and different metaheuristics have been developed. The introduced algorit…

How Physical Education Teachers’ Interpersonal Behaviour is Related to Students’ Health-Related Quality of Life

2019

Grounded in self-determination theory (SDT), this cross-sectional study tested relations of students’ perceptions of autonomy-supportive and controlling behaviour from teachers in physical education with students’ health-related quality of life (HRQoL), and the potential role of students’ perceived need satisfaction and need frustration as a mediator of these relationships. School students (N = 1031) completed self-report measures of perceived autonomy support, perceived teachers’ controlling behaviour, students’ need satisfaction and need frustration, and HRQoL. Results indicated that students’ perceptions of autonomy support from teachers was positively associated with HRQoL through need …

Tracking Formation of a Lava Lake From Ground and Space: Masaya Volcano (Nicaragua), 2014-2017

2018

A vigorously degassing lava lake appeared inside the Santiago pit crater of Masaya volcano (Nicaragua) in December 2015, after years of degassing with no (or minor) incandescence. Here we present an unprecedented-long (3 years) and continuous volcanic gas record that instrumentally characterizes the (re)activation of the lava lake. Our results show that, before appearance of the lake, the volcanic gas plume composition became unusually CO 2 rich, as testified by high CO 2 /SO 2 ratios (mean: 12.2 ± 6.3) and low H 2 O/CO 2 ratios (mean: 2.3 ± 1.3). The volcanic CO 2 flux also peaked in November 2015 (mean: 81.3 ± 40.6 kg/s; maximum: 247 kg/s). Using results of magma degassing models and budg…
