BaCe0.5Zr0.3Y0.2–xYbxO3–δ proton-conducting electrolytes for intermediate-temperature solid oxide fuel cells
(2017)This work describes new findings concerning the preparation of Y- and Yb- co-doped BaCeO3–BaZrO3 materials, their structural, microstructural, electrical characterization and application as electrolytes for solid oxide ... -
BaCeO3: Materials development, properties and application
(2014)The characteristic of a number of oxide materials, which include BaCeO3-systems, is their ability to show the proton conductivity along with oxygen-ion conductivity. Such atypical behavior for other oxides attracts great ... -
Bacillus cereus: an important foodborne pathogen
(2010)B. cereus is a spore-forming bacterium, frequently found in the environment. Most of the strains can grow at a temperature range of 10 degrees - 42 degrees C. B. cereus grows under aerobic conditions, but anaerobic growth ... -
Back pressure based multicast scheduling for fair bandwidth allocation
(2005)We study the fair allocation of bandwidth in multicast networks with multirate capabilities. In multirate transmission, each source encodes its signal in layers. The lowest layer contains the most important information and ... -
Back to design fundamentals: The step and the eye
(2019)Space Syntax has often been associated with techniques and computer methods. Its basic concept though lays beyond the techniques: it’s a way of understanding space. The fundamental idea is that space is been perceived, ... -
Backbone formation in military multi-layer ad hoc networks using complex network concepts
(2016)Modern battlefields are characterized by increasing deployment of ad hoc communications among allied entities. These networks can be seen as a complex multi-layer ad hoc network, where each layer may be an independently ... -
Backbones for Internet of Battlefield Things
(2021)The Internet of Battlefield Things is a relatively new cyberphysical system and even though it shares a lot of concepts from the Internet of Things and wireless ad hoc networking in general, a lot of research is required ... -
Background characteristics as predictors of Greek teachers’ self-efficacy
(2016)Purpose – The purpose of this paper is to investigate the relationship between elementary and secondary teachers’ background characteristics and constructs of self-efficacy, using the Teachers’ Sense of Efficacy Scale – ... -
Backhaul relaxation through caching
(2017)In this chapter the idea of content centric mobile wireless networks introduced as a solution to the traffic expansion problem faced by MNOs. We denoted the essential role that in-network caching plays in the transition ... -
Backorder penalty cost coefficient "b": What could it be?
(2010)The classical economic order quantity (EOQ) model with planned penalized backorders (PB) relies on postulating a value for the backorder penalty cost coefficient, b, which is supposed to reflect the intangible adverse ... -
Backscatter Sensors Communication for 6G Low-Powered NOMA-Enabled IoT Networks Under Imperfect SIC
(2022)The combination of nonorthogonal multiple access (NOMA) using power-domain with backscatter communication (BC) is expected to connect large-scale Internet of things (IoT) devices in the future sixth-generation era. This ... -
Backward Degree a new index for online and offline change point detection based on complex network analysis
(2022)How to identify an upcoming transition in a time series continues to be an important open research issue. In various fields of physical sciences, engineering, finance and neuroscience abrupt changes can occur unexpectedly ... -
Bacterial and archaeal phylotypes associated with distinct mineralogical layers of a white smoker spire from a deep-sea hydrothermal vent site (9 degrees N, East Pacific Rise)
(2006)A diffusely venting chimney spire from the East Pacific Rise (9 degrees N) was analysed by petrographic thin sectioning and 16S rRNA gene cloning and sequencing in parallel, to correlate microbial community composition ... -

(2006)A diffusely venting chimney spire from the East Pacific Rise (9°N) was analysed by petrographic thin sectioning and 16S rRNA gene cloning and sequencing in parallel, to correlate microbial community composition with ... -
Bacterial biofilm development during experimental degradation of Melicertus kerathurus exoskeleton in seawater
(2018)Chitinolytic bacteria are widespread in marine and terrestrial environment, and this is rather a reflection of their principle growth substrate’s ubiquity, chitin, in our planet. In this paper, we investigated the development ... -
Bacterial Bronchitis Caused by Streptococcus pneumoniae and Nontypable Haemophilus influenzae in Children The Impact of Vaccination
(2013)Background: Protracted bacterial bronchitis is a major cause of persistent cough in childhood. The organisms most commonly isolated are nontypable Haemophilus infiuenzae and Streptococcus pneumoniae. There are no studies ... -
Bacterial canine vector-borne zoonotic diseases in "One Health" concept
(2016)Canine vector-borne diseases constitute a large group of diseases transmitted by arthropods with worldwide distribution. A wide range of bacterial, viral, and parasitic agents that are transmitted by vectors cause disease ...
