The electrical properties of Bi3.25Dy0.75Ti3O12 (BDT) and Bi3.25Gd0.75Ti3O12 (BGT) ceramics were investigated. The current-voltage curve of the BGT sample exhibits a negative differential resistance behavior, whereas that of the BDT sample exhibits a simple ohmic behavior. The impedance spectrum of the BDT and BGT samples indicate that both consist of semiconducting grain and moderately insulating grain boundary regions. XRD, SEM and EPMA analyses reveal crystalline phase characterized by a Bi-layered perovskite structure of Bi4Ti3O12 and the distribution of every element is uniform. Both BDT and BGT samples exhibit randomly oriented and plate-like morphology.

Effector proteins secreted by plant pathogens play important roles in promoting colonization. Blumeria effector candidate (BEC) 1019, a highly conserved metalloprotease of Blumeria graminis f. sp. hordei (Bgh), is essential for fungal haustorium formation, and silencing BEC1019 significantly reduces Bgh virulence. In this study, we found that BEC1019 homologs in B. graminis f. sp. tritici (Bgt) and Gaeumannomyces graminis var. tritici (Ggt) have complete sequence identity with those in Bgh, prompting us to investigate their functions. Transcript levels of BEC1019 were abundantly induced concomitant with haustorium formation in Bgt and necrosis development in Ggt-infected plants. BEC1019 overexpression considerably increased wheat susceptibility to Bgt and Ggt, whereas silencing this gene using host-induced gene silencing significantly enhanced wheat resistance to Bgt and Ggt, which was associated with hydrogen peroxide accumulation, cell death, and pathogenesis-related gene expression. Additionally, we found that the full and partial sequences of BEC1019 can trigger cell death in Nicotiana benthamiana leaves. These results indicate that Bgt and Ggt can utilize BEC1019 as a virulence effector to promote plant colonization, and thus these genes represent promising new targets in breeding wheat cultivars with broad-spectrum resistance.

Bovine genital campylobacteriosis (BGC) and bovine genital trichomonosis (BGT) are globally widespread, predominantly sexually transmitted diseases that mainly affect herds in which natural mating takes place. Bulls serve as good epidemiological indicators for studying the causative agents of these diseases in cattle herds. The objective of the present work was to determine the prevalence of BGC and BGT among bulls sent to slaughterhouses in southern Minas Gerais, Brazil. Samples of preputial smegma from 200 sexually mature, non-castrated bulls of several ancestries were collected in 2013 from four regional slaughterhouses. The polymerase chain reaction (PCR) was employed to detect Tritrichomonas foetus, Campylobacter fetus subsp. fetus, and C. fetus subsp. venerealis. Isolation also was used aiming to diagnosis of BGT. All smegma samples were negative in culture for T. foetus. Molecular tests revealed 8% (16/200) of animals to be positive for T. foetus, 17.5% (35/200) for Campylobacter. fetus subsp. fetus, and 13.5% (27/200) for C. fetus subsp. venerealis. The results of the present study indicate that T. foetus, C. fetus subsp. venerealis, and C. fetus subsp. fetus are present among bulls slaughtered in southern Minas Gerais, and that BGC and BGT occur in this region. These diseases therefore need to be considered during differential diagnosis of reproductive diseases affecting cattle herds in which natural mating is employed.

abstractEnglish speakers expressing futurity have the choice of two primary verb forms, will or be going to (BGT). Previous studies establish that BGT has multiple meanings not associated with will. Langacker (1987) rejected a metaphoric analysis of BGT (time is motion) as inadequate and offered a binary feature analysis. Brisard (2001) expanded on this analysis and argued that manipulating the configurations of binary features explains the semantic differences between will and BGT. However, Brisard’s analysis overlooks the semantic overlap among will, BGT, and the simple present. Moreover, it does not provide a framework that treats will and BGT as part of the larger English modal verb system. Finally, it lacks a persuasive explanation of how the meanings associated with will versus BGT arose. We address these gaps by proposing a polysemy-based explanation that emphasizes invited inferences (e.g., Bybee, Perkins, & Pagliuca, 1994) and embodied experience; a particularly novel aspect of the analysis is that all the meanings of BGT are related straightforwardly to components of the human walk cycle. Further, we argue that the shared future meaning of will and BGT represent inter-lexical polysemy (Evans, 2015b), thus providing additional evidence for the Theory of Lexical Concepts and Cognitive Models (LCCM).

Abstract Context.—One of the major attributes of laboratory testing is cost. Although fully automated central laboratory glucose testing and semiautomated bedside glucose testing (BGT) are performed at most institutions, rigorous determinations of interinstitutional comparative costs have not been performed. Objectives.—To compare interinstitutional analytical costs of central laboratory glucose testing and BGT and to provide suggestions for improvement. Design.—Participants completed a demographic form about their institutional glucose monitoring practices. They also collected information about the costs of central laboratory glucose testing, BGT at a high-volume testing site, and BGT at a low-volume testing site, including specified cost variables for labor, reagents, and instruments. Participants.—A total of 445 institutions enrolled in the College of American Pathologists Q-Probes program. Main Outcome Measure.—Median cost per glucose test at 3 testing sites. Results.—The median (10th–90th percentile range) costs per glucose test were $1.18 ($5.59–$0.36), $1.96 ($9.51– $0.77), and $4.66 ($27.54–$1.02) for central laboratory, high-volume BGT sites, and low-volume BGT sites, respectively. The largest percentages of the cost per test were for labor (59.3%, 72.7%, and 85.8%), followed by supplies (27.2%, 27.3%, and 13.4%) and equipment (2.1%, 0.0%, and 0.0%) for the 3 sites, respectively. The median number of patient specimens per month at the high-volume BGT sites was 625 compared to 30 at the low-volume BGT sites. Most participants did not include labor, instrument maintenance, competency assessment, or oversight in their BGT estimated costs until required to do so for the study. Conclusions.—Analytical costs per glucose test were lower for central laboratory glucose testing than for BGT, which, in turn, was highly variable and dependent on volume. Data that would be used for financial justification for BGT were widely aberrant and in need of improvement.

Annotation:

The neuronal α7 nicotinic acetylcholine receptor (AChR) binds the neurotoxin α-bungarotoxin (α-Bgt). Fine mapping of the α-Bgt-binding site on the human α7 AChR was performed using synthetic peptides covering the entire extracellular domain of the human α7 subunit (residues 1–206). Screening of these peptides for 125I-α-Bgt binding resulted in the identification of at least two toxin-binding sites, one at residues 186–197, which exhibited the best 125I-α-Bgt binding, and one at residues 159–165, with weak toxin-binding capacity; these correspond, respectively, to loops C and IV of the agonist-binding site. Toxin binding to the α7(186–197) peptide was almost completely inhibited by unlabelled α-Bgt or d-tubocurarine. Alanine substitutions within the sequence 186–198 revealed a predominant contribution of aromatic and negatively charged residues to the binding site. This sequence is homologous to the α-Bgt binding site of the α1 subunit (residues 188–200 in Torpedo AChR). In competition experiments, the soluble peptides α7(186–197) and Torpedo α1(184–200) inhibited the binding of 125I-α-Bgt to the immobilized α7(186–197) peptide, to native Torpedo AChR, and to the extracellular domain of the human α1 subunit. These results suggest that the toxin-binding sites of the neuronal α7 and muscle-type AChRs bind to identical or overlapping sites on the α-Bgt molecule. In support of this, when synthetic α-Bgt peptides were tested for binding to the recombinant extracellular domains of the human α7 and α1 subunits, and to native Torpedo and α7 AChR, the results indicated that α-Bgt interacts with both neuronal and muscle-type AChRs through its central loop II and C-terminal tail.

Annotation:

The title Bender Gestalt: Screening for Brain Dysfunction (2nd ed.) indicates that the primary utility of the Bender Gestalt Test (BGT) is one of screening for the presence of brain impairment. The author, Patricia Lacks, quickly dispels this notion in the preface to her book where she states, “My book is not about how to use the BGT as a single test of ‘organicity’, a long outdated practice. Instead, the focus is on neuropsychological assessment as a continuum” (p. vii). Indeed, Lacks advocates, throughout her book, the more general use of the BGT as an important part of any standard neuropsychological test battery. She writes, “Even though the BGT has been shown to be useful for identifying persons with a wide range of cognitive impairment, it primarily assesses disordered perceptual-motor and executive functions” (p. 27). Unfortunately, Lacks does not provide the reader with any data to support her above statement regarding what the BGT actually measures. Before taking the latter point any further, allow me to briefly describe the BGT and its history.

The purpose of the current study was to develop Brigatinib (BGT)-loaded nanospanlastics (BGT-loaded NSPs) (S1-S13) containing Span 60 with different edge activators (Tween 80 and Pluronic F127) and optimized based on the vesicle size, zeta potential (ZP), and percent entrapment efficiency (%EE) using Design-Expert® software. The optimum formula was recommended with desirability of 0.819 and composed of Span-60:Tween 80 at a ratio of 4:1 and 10 min as a sonication time (S13). It showed predicted EE% (81.58%), vesicle size (386.55 nm), and ZP (−29.51 mv). The optimized nanospanlastics (S13) was further coated with chitosan and further evaluated for Differential Scanning Calorimetry (DSC), X-ray Diffraction (XRD), in vitro release, Transmission Electron Microscopy (TEM), stability and in-vitro cytotoxicity studies against H-1975 lung cancer cell lines. The DSC and XRD revealed complete encapsulation of the drug. TEM imagery revealed spherical nanovesicles with a smooth surface. Also, the coated formula showed high stability for three months in two different conditions. Moreover, it resulted in improved and sustained drug release than free BGT suspension and exhibited Higuchi kinetic release mechanism. The cytotoxic activity of BGT-loaded SPs (S13) was enhanced three times in comparison to free the BGT drug against the H-1975 cell lines. Overall, these results confirmed that BGT-loaded SPs could be a promising nanocarrier to improve the anticancer efficacy of BGT.

Geopolymer, a sustainable alternative to ordinary Portland cement (OPC), offers reduced embodied energy, lower carbon emissions, enhanced durability, eco-compatibility, and waste valorization potential. In confining structural members, geopolymer still has limitations with respect to its brittleness and other properties. Enhancing the properties of geopolymer by adding banana fibers (BF) and fly ash (FA) to form banana geotextile-reinforced geopolymer mortar (BGT-RGM) as confining material, is investigated in this experimental study. BGT-RGM is a textile-reinforced mortar with varying thickness of BF-reinforced geopolymer mortar (BFRGM) through NaOH-treated 10 mm BFs and 2 mm banana geotextile (BGT) having varied grid spacings. To develop BGT-RGM, the physical, mechanical, and chemical properties of the BFs were determined, while BFRGMs were evaluated for compressive and dog-bone tensile strengths, workability, scanning electron microscopy (SEM) imaging, and thermogravimetric analysis (TGA). The BGT-RGM-confined and unconfined concrete were evaluated, and the strength variations were imparted by the confinement as reflected on the stress-strain curves. The local crack formation mode of failure was also determined through crack patterns during an axial load test. The BGT-RGM with 20 mm thickness of BFRGM with 15 mm and 20 mm geotextile grid spacings, exhibited 33.3% and 33.1% increases in strength, respectively. Future investigations towards the development and application of BGT-RGM are also discussed.

Annotation:

Twenty three stable monoclonal antibodies (mAbs) against β1-bungarotoxin (β1-bgt) were prepared by the hybridoma technique. Seven of the 23 mAbs (mAbs 2, 6, 8, 11, 17, 21 and 22) could inhibit more than 70% of phospholipase A2 activity of β1-bgt and neutralize the toxin. Six of these neutralizing mAbs (mAbs 2, 6, 8, 17, 21 and 22) recognized continuous epitopes on the A chain of β1-bgt and the other one (mAb 11) recognized a conformational epitope on the toxin. The continuous epitopes of these six mAbs were mapped using synthetic peptide and proteolytic enzymes. Experimental results indicate that mAb 17 recognized the A-chain residues 31-37; mAbs 2 and 8 recognized residues 46-51; mAbs 21 and 22 recognized residues 91-98; and mAb 6 recognized residue 100-106. The competitive-antibody-binding inhibition experiments showed that the affinity of these neutralizing mAbs to the native β1-bgt is compatible with synthetic peptides. Furthermore, mice immunized with BSA-conjugated A-chain-peptide sequences A(31-37), A(46-51), A(91-98) or A(100-106) were protected from a high-dose β1-bgt challenge. Subsequently, the peptide-immunized sera were passively injected into Balb/c mice and a significantly protective effect was also observed. To our knowledge, this study is the first systematic demonstration of multiple neutralizing B-cell epitopes of β1-bgt, and this study is also the first report of the protective synthetic-peptide vaccine against β1-bgt challenge.

Ce travail a pour objet l’étude de l’un des systèmes les plus prometteurs en tant que substitut au PZT, le ternaire Bi0,5Na0,5TiO3 - BaTiO3 - Bi0,5K0,5TiO3. La première partie de la thèse s’est focalisée sur la synthèse par voie solide de ce système et a permis une estimation plus affinée de la zone de transition de phase morphotropique. Dans une seconde partie, nous nous sommes centrés sur l’élaboration de poudres réactives de BNT par voie hydrothermale. Bien que les divers protocoles mis au point ont permis l’obtention de poudres microniques et cristallisées, toutes se distinguent par l’apparition de phases thermiquement instables en quantités infimes mais néanmoins suffisantes pour entraîner l’apparition d’une macroporosité après frittage. Diverses techniques de lavage ont été développées pour éliminer ces phases métastables. Un compromis a dû être réalisé entre la qualité de l’élimination de ces phases non désirées et le maintien de la composition chimique de la phase majoritaire. Le taux de densification et les propriétés piézoélectriques obtenus sur ces céramiques sont largement comparables à la voie solide. L’étude de la cosynthèse BNT - BT par thermolyse hydrothermale de la composition binaire 0,935 BNT - 0,065 BT n’a pu aboutir et a mis en évidence la précipitation préalable et définitive du titanate de bismuth Bi12TiO20
This study focuses on the study of one of the most promising systems as an alternative to PZT, the Bi0,5Na0,5TiO3 - BaTiO3 - Bi0,5K0,5TiO3 ternary system. The first part of the thesis consists on the solid state synthesis of this system and has allowed a more accurate estimation of the morphotropic phase boundary location. In a second part, we focused this study on the development of BNT powders hydrothermal synthesis. Although various protocols have developed the production of fine and single phased powders, all of them are characterized by the presence of thermally unstable phases in minor quantities but nevertheless sufficient to let appear a strong porosity after sintering. Various washing techniques have been developed to eliminate these metastable phases. A compromise between the quality of the metastable phase elimination and the preservation of the major phase chemical composition must be realized. The densification ratio and piezoelectric properties obtained for these ceramics are widely comparable to the solid route synthesized ones. The BNT - BT cosynthesis study of the 0,935 BNT - 0,065 BT binary composition put in evidence the prerequisite and definitive bismuth titanate Bi12TiO20 precipitation

På Beckholmen ligger stockholmsregionens enda aktiva reparationsvarv med kapacitet att ta emot såväl större fartyg samt skärgårdstrafikens fartyg. För att kunna bedriva verksamheten på ett säkert och miljövänligt sätt krävs infrastrukturella investeringar i form av byggnader och anläggningar. Stockholms stad har påbörjat ett programarbete och presenterat ett förslag till detaljplan som möjliggör dessa investeringar. Då det handlar om stora investeringar och förändringar i stadsbilden är den nya detaljplanen ett känsligt projekt, särskilt om varvsverksamheten skulle hamna i ekonomiska svårigheter. I det förslag till detaljplan som presenterats hösten 2012 har varsverksamhetens funktioner lagts inom en och samma byggnadsvolym, som till en följd blir väldigt stor. Frågeställningen i ”Beckholmen bit för bit” är om en detaljplan som låter verksamheten växa mer inkrementellt fördelat på fler byggnader kan göra projektet mer flexibelt. Efter studier av varvsverksamhetens program samt volym och planstudier, blir slutsatsen att det finns fördelar med att fördela varvsfunktionerna på fler byggnadsvolymer. Särskilt om byggnaderna gestaltas på ett sätt så att kompositionen är öppen för förändring. Ett förslag på en gestaltning som uppfyller dessa egenskaper presenteras även.
The only active shipyard in the Stockholm region with capacity for large ships and the archipelago fleet is situated at Beckholmen. Large investments in infrastructure and buildings are needed in order to secure the enviroment and worker safety. The city has presented a proposal for new planning enabeling these investments. As the investment are large and the site is sensitive the project has many potential risks, especially if the shipyard should encounter economic difficulties in the future. In the citys planning proposal presented in 2012 the whole program for the shipyard is contained within one single volume. The question at issue in ”Beckholmen bit by bit” thus is if planning that splits the program into separate buildings and permits incremental growth is prefarable. After program studies, volume and plan studies the conclusion is that there are many advantages with planning that encourages incremental growth of the shipyard at Beckholmen, especially if the building design is open to change from the beginning. A proposal of a planning and design fulfilling these qualities is also presented.

L’objectif du présent travail est de concevoir, réaliser et optimiser des matériaux accordables pour des applications en électronique à hautes fréquences. Le composant le plus simple permettant de mettre à profit cette étude est le condensateur accordable avec une tension continue qui peut être ensuite intégrée dans des dispositifs microondes accordables ou reconfigurables. Le condensteur peut être en couches minces ou en céramique. Pour réaliser de tels composants, on doit utiliser des matériaux présentant de faible pertes diélectriques, une permitivité élevée, une accordabilité importante et une bonne stabilité de la fréquence de résonance avec la température. Pour cela, nous avons mené une étude sur des matériaux ferroélectriques classiques et relaxeurs afin, d’une part d’optimiser les conditions de synthèse, et d’autre part d’améliorer leurs propriétés électriques pour des applications radiofréquences et microondes. Nous avons étudié des matériaux ferroélectriques de phase pérovskite. Il s’agit du titane de baryum et de strontium (BST) qui est un ferroélectrique classique, du titane de baryum et de zircone (BZT) qui selon sa composition peut être classique ou relaxeur et des dérivées du BZT obtenues par substitution au niveau des sites pérovskites a et b respectivement par du bismuth et par du zinc-niobium. Nous avons aussi synthétisé et caractérisé des matériaux de phase pyrochlore de formule Bi1. 5ZnNb1. 5O7. Ces études vont de l’élaboration de tous ces matériaux sous forme de céramiques et de couches minces, suivies de caractérisations physico-chimiques, structurales, diélectriques et ferroélectriques dans une large gamme de fréquences et de températures
The main objective of this work is to design, implement and optimize tunable materials for electronic applications at high frequencies. The easiest component to build on this study is the tunable capacitor with a voltage which can then be integrated into microwave devices such as tunable or reconfigurable resonators, filters, antennas. . . Etc. The capacitor can be either thin film or ceramic-based. To produce such components we must use materials which must have low dielectric loss, high dielectric permittivity, high tunability and stability of the resonant frequency of the capacitor with the temperature. For this, we conducted a detailed study of classical and relaxor ferroelectric materials in order, firstly to optimize the synthesis conditions, and secondly to improve their electrical properties for radiofrequencies and microwave applications. We have studied ferroelectric materials with perovskite phase, namely barium titanate strontium (BST) which is a classical ferroelectric and barium zirconium (BZT) which according to its composition can be a classical ferroelectric or relaxor ferroelectric and the derivatives of BaZr0. 1Ti0. 9O3 obtained by substituting bismuth and zinc-niobium respectively at A and B sites of the perovskite phase. We also synthesized and characterized the pyrochlore phase materials of bismuth zinc niobate, with composition of Bi1. 5ZnNb1. 5O7. The studies we have done range from the development of these materials in the form of ceramics and thin films, followed by characterizations to determine their physico-chemical properties, structural dielectric and ferroelectric in a range wide of frequencies and temperature

In the presented thesis, lead-free Ba(Ti0.8Zr0.2)O3-(Ba0.7Ca0.3)TiO3 (BZT-BCT) thin films were deposited on Pt/TiO2/SiO2/Si substrates using chemical solution deposition method and then the effect of process parameters were investigated to obtain optimum parameters of these lead-free thin films. The phase was selected near to the morphotropic phase boundary (MPH) to increase the number of polarization directions where rhombohedral and tetragonal phases exist together. In this study, the effect of sintering temperatures on microstructure, dielectric and ferroelectric properties were studied systematically. Among the various high-quality BZT-BCT thin films with uniform thickness, the optimum dielectric and ferroelectric responses were observed for films annealed at 800 oC for 1 h sintering time. The thickness was kept constant for all measurements as 500 nm (triple layered films). Therefore, the average grain sizes were found around 60 nm for samples sintered at 700,750 and 800 oC. BZT-BCT thin films sintered at 800 oC showed effective remnant polarization and coercive field values of 2.9 µ
C/cm2 and 49.4 kV/cm, together with a high dielectric constant and low loss tangent of 365.6 and 3.52 %, respectively, at a frequency of 600 kHz due to pure perovskite phase showing full crystallization and minimum surface porosity obtained at this temperature.

Research on inverted pendulum has gained momentum over the last decade on a number of robotic laboratories over the world; due to its unstable proprieties is a good example for control engineers to verify a control theory. To verify that the pendulum can balance we can make some simulations using a closed-loop controller method such as the linear quadratic regulator or the proportional–integral–derivative method. Also the idea of robotic teleoperation is gaining ground. Controlling a robot at a distance and doing that precisely. However, designing the tool to takes the best benefit of the human skills while keeping the error minimal is interesting, and due to the fact that the inverted pendulum is an unstable system it makes a compelling test case for exploring dynamic teleoperation. Therefore this thesis focuses on the construction of a two-wheel inverted pendulum robot, which sensor we can use to do that, how they must be integrated in the system and how we can use a human to control an inverted pendulum. The inverted pendulum robot developed employs technology like sensors, actuators and controllers. This Master thesis starts by presenting an introduction to inverted pendulums and some information about related areas such as control theory. It continues by describing related work in this area. Then we describe the mathematical model of a two-wheel inverted pendulum and a simulation made in Matlab. We also focus in the construction of this type of robot and its working theory. Because this is a mobile robot we address the theme of the teleoperation and finally this thesis finishes with a general conclusion and ideas of future work.

As redes sem fio ad hoc surgiram para estender a mobilidade e a flexibilidade no ambiente sem fio, onde um conjunto de nós, que podem agir como roteadores, formam a infra-estrutura de roteamento na rede. A maioria dos protocolos de roteamento propostos não utiliza mecanismos de segurança, pois assumem que o ambiente é composto apenas por nós confiáveis. Mas devido à mudança dinâmica de topologia e ambiente aberto, uma rede ad hoc é extremamente vulnerável à presença de nós maliciosos os quais podem degradar desempenho ou até mesmo impedir o funcionamento da rede. Para evitar ou minimizar os problemas causados pela falta de segurança, os seguintes protocolos de roteamento seguro foram propostos: Ariadne, SAODV, BFTR, SEAD e ARAN. Neste contexto, a presente dissertação tem como objetivo analisar estes protocolos de roteamento seguro utilizados em redes sem fio ad hoc e propor melhorias nos mecanismos de segurança projetados para proteger a rede contra ataques interrupção de roteamento e de consumo de recursos. Como resultado desta análise, é proposto o Ariadne-BFT (Ariadne Best-effort Fault-Tolerant), uma extensão do protocolo de roteamento seguro Ariadne baseado nos algoritmos de descoberta e seleção de rotas do protocolo BFTR. O Ariadne-BFT incrementa a segurança no roteamento em relação ao protocolo Ariadne original, com a proteção contra o ataque Blackhole. Experimentos são executados sob a forma de simulações para análise e comparação de desempenho, através das quais é demonstrado que o protocolo Ariadne-BFT possui um desempenho superior em relação às métricas latência e razão de entrega de pacotes.

Abstract The computation of exterior wave problems at low wave numbers can become prohibitively expensive when higher circumferential modes are significant. An analysis of the effect of wave number on scattering problems, with local absorbing boundary conditions specified on simple shapes as on-surface radiation conditions, provides guidelines for satisfactory performance. Excessive computational cost may be avoided for most practical applications.

Annotation:

This paper presents a novel and simple technique for the kinematic analysis of bevel gear trains (BGT). The approach is based on edge-oriented graphs for efficient computation of BGT’s relative and absolute velocities of links using incidence matrices. The kinematic equations are generated in matrix form using a cycle basis from a cycle matroid. The set of independent equations is automatically obtained from matrix orthogonalities and not by taking derivatives. Equation coefficients are expressed as function of speed ratios and have minimal variables. Then the relationships between the output and input angular velocities can be determined. In addition, a simple procedure is demonstrated to check for mechanism singularities. The method presented here has general applicability and can be employed for spatial geared mechanisms with any number of gears and degrees of freedom as illustrated by numerical examples of robotic wrist mechanisms.
