Metodología analítica para el control de calidad en ambientadores higiénicos basados en la cuantificación de sus componentes mediante cromatografía de gases acoplada a espectrometría de masas (GC/MS).

Bartolomé Moro, Luis Javier (2016-04-08)

Increasingly, the quality control on production processes is becoming imperative in industry. This control includes the analysis of raw materials and their suppliers. In the hygiene products industry, this control is vital ...

Pan-European rural monitoring network shows dominance of NH3 gas and NH4NO3 aerosol in inorganic atmospheric pollution load

Tang, Y.S; Flechard, C.H.; Dämmgen, U.; Vidic, S.; Djuricic, V.; Mitosinkova, M.; Uggerud, H.T; Simmons, I.; Dragosits, U; Nemitz, E.; Twigg, M.; van Dijk, N.; Fauvel, Y.; Sanz, F.; Ferm, M.; Perrino, C.; Catrambone, M.; Leaver, D.; Braban, C.H.; Cape, J-N.; Heal, M.R; Sutton, M.A. (ATMOSPHERIC CHEMISTRY AND PHYSICS, 2021)

A comprehensive European dataset on monthly atmospheric NH3, acid gases (HNO3, SO2, HCl), and aerosols (NH+4, NO3, SO24 , Cl, NaC, Ca2C, Mg2C/ is presented and analysed. Speciated measurements were made with a low-volume ...

Ni-Mn-Sn-Cu Alloys after Thermal Cycling: Thermal and Magnetic Response

Wederni, Asma; Ipatov, Mihail; González Estévez, Julián María; Khitouni, Mohamed; Suñol, Joan-Josep (MDPI, 2021-11-13)

Heusler Ni-Mn-Sn-based alloys are good candidates for magnetic refrigeration. This application is based on cycling processes. In this work, thermal cycles (100) have been performed in three ribbons produced by melt-spinning ...

Álvarez, Álvaro; Calleja Ochoa, Amaia

; Ortega Rodríguez, Naiara; López de Lacalle Marcaide, Luis Norberto

(MDPI, 2018-05)

In this paper, a five-axis machining process is analyzed for large spiral-bevel gears, an interesting process for one-of-kind manufacturing. The work is focused on large sized spiral bevel gears manufacturing using universal ...

On the non-proportionality between wheel/rail contact forces and speed during wheelset passage over specific welds

Correa García, Nekane

; García Vadillo, Ernesto

; Santamaría Manrique, Javier

; Blanco-Lorenzo, Julio (Elsevier, 2018-01)

This study investigates the influence on the wheel-rail contact forces of the running speed and the shape and position of weld defects along the track. For this purpose, a vertical dynamic model in the space domain is used. ...
