New approach to suppress mutual coupling between longitudinal-slotted arrays based on SIW antenna loaded with metal-fences working on VHF/UHF frequency-bands: study, investigation, and principle
In this work it is demonstrated that substrate integrated waveguide longitudinal slotted array antenna (SIWLSAA) which is loaded with metal fences exhibits high-isolation across VHF/UHF bands. A reference SIWLSAA used for ... -
New challenges in organic fertilization: soil quality indicators under long-term sewage sludge application
(2023) Tesis doctoral / Doktoretza tesiaSoils represent a fundamental part of life on Earth and represent a crucial player on climate change action, for their capacity to sequester atmospheric carbon (C) through organic matter stabilization, constituting one of ... -
New functions for Cyt proteins and sporulation determinants in Bacillus thuringiensis
(2023) Tesis doctoral / Doktoretza tesiaEn este estudio, primero nos centramos a encontrar nuevas proteínas insecticidas y factores sinérgicos con actividad contra larvas de A. albopictus. Nuestro primer objetivo, fue caracterizar la actividad individual de ... -
A new role for aldosterone/mineralocorticoid receptor pathway in the development of mitral valve prolapse
La hipótesis de trabajo es que la vía Aldosterona/Receptor Mineralocorticoide (Aldo/RM) podría jugar un papel en el desarrollo del prolapso de la válvula mitral (PVM), modulando la activación de las células intersticiales ... -
A new study to suppress mutual-coupling between waveguide slot array antennas based on metasurface bulkhead for MIMO systems
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. ... -
A new waveguide slot array antenna with high isolation and high antenna bandwidth operation on Ku- and K- Bands for radar and MIMO systems
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 ... -
Nodule carbohydrate catabolism is enhanced in the Medicago truncatula A17-Sinorhizobium medicae WSM419 symbiosis
The symbiotic association between Medicago truncatula and Sinorhizobium meliloti is a well-established model system in the legume–Rhizobium community. Despite its wide use, the symbiotic efficiency of this model has been ... -
Non-invasive aging analysis of lithium-ion batteries in extreme cold temperatures
This paper presents a non-invasive technical analysis of the degra-dation of four lithium-ion batteries (LIBs) used in extreme frigid weather. In contrast to other studies in which the batteries were tested in laboratory ... -
Noncontiguous operon is a genetic organization for coordinating bacterial gene expression
Bacterial genes are typically grouped into operons defined as clusters of adjacent genes encoding for proteins that fill related roles and are transcribed into a single polycistronic mRNA molecule. This simple organization ... -
A novel 0.3-0.31 THz GaAs-based transceiver with on-chip slotted metamaterial antenna based on SIW technology
This paper presents a novel on-chip antenna with fully integrated 0.3-0.31 THz transceiver is implemented on 0.5μm GaAs substrate, and comprises a voltage-controlled oscillator (VCO), a buffer amplifier, a modulator stage, ... -
Novel blaROB-1-bearing plasmid conferring resistance to β-lactams in Haemophilus parasuis isolates from healthy weaning pigs
Haemophilus parasuis, the causative agent of Glässer’s disease, is one of the early colonizers of the nasal mucosa of piglets. It is prevalent in swine herds, and lesions associated with disease are fibrinous polyserositis ... -
Novel concentric hexagonal-shaped RFID tag antenna with T-shaped stub matching
This paper presents a unique concentric hexagonal-shaped ring antenna for radio frequency identification (RFID) tags. The rings are excited with a common microstrip feedline. The radiation characteristics of the antenna ... -
Novel method for an optimised calculation of the cross-sectional distribution of live loads on girder bridge decks
One of the main goals in the design of girder bridge deck systems is to determine the cross-sectional distribution of live loads across the different girders that make up the cross-section of the deck. Structural grillage ... -
Novel multivariate methods to track frequency shifts of neural oscillations in EEG/MEG recordings
Instantaneous and peak frequency changes in neural oscillations have been linked to many perceptual, motor, and cognitive processes. Yet, the majority of such studies have been performed in sensor space and only occasionally ... -
Nuclear engineering and technology transfer: the Spanish strategies to deal with US, French and German nuclear manufacturers, 1955–1985
We analysed the process of construction and connection to the electrical grid of four Spanish nuclear power plants with different financial and technological foreign partners: those of Zorita (PWR by Westinghouse), Garoña ... -
Nuclear power for a dictatorship: state and business involvement in the Spanish atomic program 1950-1985
Spain was the first developing country to exploit a nuclear power plant commercially. By the early 1970s Spain had become the major nuclear client of the USA, the world’s largest reactor exporter. Despite its importance, ... -
On fixed point theory in partially ordered sets and an application to asymptotic complexity of algorithms
The celebrated Kleene fixed point theorem is crucial in the mathematical modelling of recursive specifications in Denotational Semantics. In this paper we discuss whether the hypothesis of the aforementioned result can be ... -
On the characterization of lithium-ion batteries under overtemperature and overcharge conditions: identification of abuse areas and experimental validation
Although lithium-ion batteries have gained considerable popularity in renewable energy and electric vehicle applications, their safety still remains a concern under certain voltage, temperature, or state of charge conditions. ... -
Onset of irreversible reactions in overcharging lithium-ion cells: an experimental and modeling approach
