Identification of lptA, lpxE, and lpxO, three genes involved in the remodeling of Brucella cell envelope
(Frontiers Media, 2018)
info:eu-repo/semantics/article,
The brucellae are facultative intracellular bacteria that cause a worldwide extended zoonosis. One of the pathogenicity mechanisms of these bacteria is their ability to avoid rapid recognition by innate immunity because ...
Tree-to-tree competition in mixed European beech-Scots pine forests has different impacts on growth and water-use efficiency depending on site condition.
(WileyBritish Ecological Society, 2018)
Artículo / Artikulua,
Mixed conifer-hardwood forests can be more productive than pure forests and they are increasingly considered as ecosystems that could provide adaptation strategies in the face of global ...
Tunable deflection and asymmetric transmission of THz waves using a thin slab of graphene-dielectric metamaterial, with and without ENZ components
(Optical Society of America, 2018)
Artículo / Artikulua,
Tunable deflection of obliquely incident, linearly polarized terahertz waves is theoretically studied in a wide frequency range around 20 THz, by combining a thin slab of graphene-dielectric metamaterial (with ten layers ...
Antenna mutual coupling suppression over wideband using embedded periphery slot for antenna arrays
(MDPI, 2018)
info:eu-repo/semantics/article,
This paper presents a new approach to suppress interference between neighbouring radiating elements resulting from surface wave currents. The proposed technique will enable the realization of low-profile implementation of ...
Multi-scale approach to forest functioning of Pinus sylvestris L. and Fagus sylvatica L. mixtures of the Pyrenees under global change
(2018)
info:eu-repo/semantics/doctoralThesis,
Hoy en día, los bosques mixtos son cada vez más reconocidos como superiores a los bosques puros en cuanto a la provisión de una completa gama de bienes y servicios ecosistémicos. La gestión de los bosques en una condición ...
Interaction between closely packed array antenna elements using meta-surface for applications such as MIMO systems and synthetic aperture radars
(Wiley, 2018)
info:eu-repo/semantics/article,
The paper presents a technique to enhance the isolation between adjacent radiating elements that is common in densely packed antenna arrays. Such antennas provide frequency beam-scanning capability needed in multiple-input ...
A new waveguide slot array antenna with high isolation and high antenna bandwidth operation on Ku- and K- Bands for radar and MIMO systems
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
In this paper a novel technique is proposed to reduce the mutual coupling between the radiating elements of a waveguide slot array antenna. This is achieved by inserting slots between the waveguide oval shaped slots. The ...
Chemical and mechanical stability of air annealed cathodic arc evaporated CrAlON coatings
(Elsevier, 2018)
info:eu-repo/semantics/article,
This study reports the synthesis and characterization of ternary Cr-Al-O and quaternary Cr-Al-O-N coatings deposited by cathodic arc physical vapour deposition, for various nitrogen and oxygen mass flow ratios during the ...
CrAlON CAE-PVD coatings for oxidation and wear protection of TZM alloys in FAST sintering applications
(Elsevier, 2018)
info:eu-repo/semantics/article,
In this work CrAlO and CrAlO/CrAlN multilayers deposited by cathodic arc evaporation are evaluated as protective films in metal and ceramic powder FAST sintering tool dies fabricated in titanium-zirconium-molybdenum allows ...
A new study to suppress mutual-coupling between waveguide slot array antennas based on metasurface bulkhead for MIMO systems
(IEEE, 2018)
info:eu-repo/semantics/conferenceObject,
In this paper, a new method is proposed to reduce mutual coupling between waveguide slot array (WSA) antennas based on metasurface technology. This is achieved by placing a metasurface bulkhead between the two WSA antennas. ...
