NH4HCO3–water solutions regeneration in RED closed loop applications
2017
Reverse Electrodialysis (RED) in closed loop arrangement (Reverse Electrodialysis Heat Engine - REDHE) is a promising technology to convert low-grade waste heat into electricity. RED is a membrane process exploiting the salinity gradient between a concentrated and a diluted solution to generate electrical current. Due to the transfer phenomena occurring in the RED unit, the two exiting solutions are partially mixed. Thermal regeneration processes can be used to restore the initial conditions of the two solutions, thus closing the loop. In this regard, ammonium hydrogen carbonate (NH4HCO3) salt solutions are suitable for such applications, being able to decompose at temperatures above 40-45 …
Search for Light Dark Matter Interactions Enhanced by the Migdal Effect or Bremsstrahlung in XENON1T.
2019
Direct dark matter detection experiments based on a liquid xenon target are leading the search for dark matter particles with masses above ∼5 GeV/c2, but have limited sensitivity to lighter masses because of the small momentum transfer in dark matter-nucleus elastic scattering. However, there is an irreducible contribution from inelastic processes accompanying the elastic scattering, which leads to the excitation and ionization of the recoiling atom (the Migdal effect) or the emission of a bremsstrahlung photon. In this Letter, we report on a probe of low-mass dark matter with masses down to about 85 MeV/c2 by looking for electronic recoils induced by the Migdal effect and bremsstrahlung us…
Taloyhtiöistä tulevaisuuden energiatuottajia : muutospolut vuoteen 2035 ja murrosareena tiedon yhteistuotannon menetelmänä
2020
Noin neljännes Suomen asuntokannasta koostuu taloyhtiöistä. Niistä merkittävä osa tarvitsee lähivuosina korjauksia, joiden avulla voidaan kehittää rakennuskannassa tapahtuvaa hajautettua energiantuotantoa esimerkiksi aurinkopaneelien ja lämpöpumppuratkaisujen avulla. Vuonna 2018 voimaan tullut EU:n energiayhteisösääntely luo yhdessään meneillään olevat kansallisten sääntelymuutosten kanssa perustan, jonka varassa taloyhtiöt voivat vahvistaa kansalaisten energiantuottajaroolia tulevaisuudessa. Murros taloyhtiöiden kestävään energiantuotantoon on haaste, joka edellyttää useiden yhteiskunnan osa-alueiden näkökulmien ja toimijoiden kokoamista yhteen. Tätä tavoitetta varten järjestettiin vuonna …

Triggering sustainability communication in a B2B context: combining action research and sensemaking
2021
PurposeThe paper explores processes associated with the adoption of corporate sustainability communication in a B2B context. It employs a combined action research and sensemaking approach to document moments that precede the initiation of external sustainability communication.Design/methodology/approachThe paper is the outcome of an action research project, where we examine the case of one industrial company that was silent on its multiple sustainability-related practices, but recently decided to become more transparent to the outside world. A processual approach to sensemaking is adopted to show how organisational and non-organisational members actively participated in meaning co-construct…
Etude théorique de surfaces d'énergie potentielle, de moment dipolaire et de polarizabilité des complexes de van der Waals CH4-N2 et C2H4-C2H4
2010
In the present thesis both ab initio and analytical calculations were carried out for thepotential energy, dipole moment and polarizability surfaces of the weakly bound van der Waals complexes CH4-N2 and C2H4-C2H4 for a broad range of intermolecular separations and configurations in the approximation of the rigid interacting molecules. For ab initio calculations the CCSD(T), CCSD(T)-F12 and less computationally expensive methods such as MP2, MP2-F12, SAPT, DFT-SAPT were employed (for all methods the aug-cc-pVTZ basis set was used). The BSSE correction was taken into account during the calculations. The analytical calculations were performed in the framework of the classical long-range appro…
Les limites de la théorie du salaire d'efficience
1998
Efficiency wage theory, evolved by the "new keynesians", is part of a research programme concerned with explaining "involuntary" unemployment as part of the "general equilibrium". So, these works are a synthesis attempt of neo-classical and keynesian analyses in the employment area. Indeed, the authors place their analysis in a walrasian framework, but they integrate a keynesian concept to complete their models. In order to achieve their purpose, the efficiency wage theorists formulate two propositions on which their argument is based: 1° the relation supposed rising between the rate of wage and the productivity of wage earners, 2° the determination of the rate of wage outside the market. W…
