Computational Methods for Modelling and Optimization of Flow Control Devices
(MDPI, 2020-07-19)
Over the last few years, the advances in size and weight for wind turbines have led to the development of flow control devices. The current work presents an innovative method to model flow control devices based on a cell-set ...
A review on the valorization of CO2. Focusing on the thermodynamics and catalyst design studies of the direct synthesis of dimethyl ether
(Elsevier, 2022-08)
The direct synthesis of dimethyl ether (DME) on bifunctional catalysts is highly attractive for valorizing CO2 and syngas derived from biomass gasification and is a key process to reduce greenhouse gas emissions. DME economy ...
Explaining Public-Private Partnership Projects through Political Factors: An Assessment of Developing Countries
(Sage, 2021-09-13)
This paper analyses the effect of political factors on the use of PPPs in developing countries. According to a sample of 80 low- and middle-income countries over the period 1995-2017, our findings suggest that PPP projects ...
Analysing the link between corruption and PPPs in infrastructure projects: an empirical assessment in developing countries
(Taylor & Francis, 2021-10-21)
This study analyses the relationship between Public-Private Partnerships (PPPs) and corruption. To do this, several econometric analyses were developed using a sample of 92 low- and middle-income countries over the period ...
Effect of privatisation on income inequality: A European analysis
(Springer Nature, 2020-06-15)
This study analyses the link between privatisation reforms and income inequality on a sample of 25 European countries between 2003 and 2013. Previous literature has related privatisations with the level of poverty, welfare, ...
Conditions for the joint conversion of CO2 and syngas in the direct synthesis of light olefins using In2O3−ZrO2/SAPO-34 catalyst
(ACS, 2021-11-09)
The conditions for promoting the joint conversion of CO2 and syngas in the direct synthesis of light olefins have been studied. In addition, given the relevance for the viability of the process, the stability of the ...
Kinetic modeling and reactor design of the direct synthesis of dimethyl ether for CO2 valorization. A review
(Elsevier, 2022-08-04)
The direct synthesis of dimethyl ether (DME) is considered one of the most attractive routes for valorizing CO2 and syngas on a large scale. DME has a high cetane number and its properties are similar to those of liquefied ...
Herritartasuna aztergai: zer diote Hego Euskal Herriko gizarte-mugimenduek?
(2021)
Herritartasuna, izatez, kontzeptu aldakor eta eztabaidatua da. Hego Euskal Herriko gizarte-mugimenduek herritartasunaz garatzen duten diskurtsoa aztertzea da artikulu honen helburua. Ikuspegi kualitatibo batetik, feminismoan, ...
Model validation of a packed bed LTA membrane reactor for the direct synthesis of DME from CO/CO2
(2020-10-16)
A model for simulating the direct synthesis of dimethyl ether (DME) in a packed bed membrane reactor (PBMR) has been validated, using a LTA zeolite hydrophilic membrane in a lab-scale reaction equipment. In the model, ...
ADITU: A mesh-free formulation for the solution of Helmholtz equation in bounded and unbounded domains
(Elsevier, 2022-06-01)
This work describes a mesh-free collocation formulation for the acoustic fluid–fluid coupling among
non-homogeneous bounded and unbounded fluid domains. The proposed formulations use series
of functions that are generated ...
