Abstract:
Pepper vein banding virus (PVBV) is a distinct species in the Potyvirus genus which infects economically important plants in several parts of India. Like other potyviruses, PVBV encodes multifunctional proteins, with several interaction partners, having implications at different stages of the potyviral infection. In this review, we summarize the functional characterization of different PVBV-encoded proteins with an emphasis on their interaction partners governing the multifunctionality of potyviral proteins. Intrinsically disordered domains/regions of these proteins play an important role in their interactions with other proteins. Deciphering the function of PVBV-encoded proteins and their interactions with cognitive partners will help in understanding the putative mechanisms by which the potyviral proteins are regulated at different stages of the viral life-cycle. This review also discusses PVBV virus-like particles (VLPs) and their potential applications in nanotechnology. Further, virus-like nanoparticle-cell interactions and intracellular fate of PVBV VLPs are also discussed.

Abstract:
A survey conducted in pepper-growing tracts of Karnataka State, covering 165 fields in 33 villages, revealed the occurrence of many pepper mosaic diseases. Based on reactions on selected test plants, the viruses were identified as pepper vein banding virus (PVBV), pepper veinal mottle virus, potato virus Y, cucumber mosaic virus, and tobacco mosaic virus. Among these, PVBV was the most prevalent. PVBV was purified from infected leaves of Capsicum annuum cv. California Wonder. Electron microscopy revealed flexuous rod-shaped particles in the purified preparations. The coat protein (CP) molecular weight was 35,000, which is similar to members of the Potyvirus group. As in other potyviruses, the CP underwent proteolytic degradation to a fragment with a molecular weight of 31,000. Both of these bands cross-reacted with antibodies against tobacco etch virus in Western blots. Polyclonal antibodies were produced against PVBV. Cross-reactivity studies with other potyviral antisera showed that PVBV is serologically closer to peanut mottle virus than to peanut stripe virus or sorghum potyvirus. N-terminal sequence analysis of the intact CP and trypsin-resistant core revealed that PVBV is a distinct member of the Potyvirus group.

Abstract:
Common bean (Phaseolus vulgaris L.) is the primary source of protein and nutrients in the majority of households in sub-Saharan Africa. However, pests and viral diseases are key drivers in the reduction of bean production. To date, the majority of viruses reported in beans have been RNA viruses. In this study, we carried out a viral metagenomic analysis on virus symptomatic bean plants. Our virus detection pipeline identified three viral fragments of the double-stranded DNA virus Pelargonium vein banding virus (PVBV) (family, Caulimoviridae, genus Badnavirus). This is the first report of the dsDNA virus and specifically PVBV in legumes to our knowledge. In addition two previously reported +ssRNA viruses the bean common mosaic necrosis virus (BCMNVA) (Potyviridae) and aphid lethal paralysis virus (ALPV) (Dicistroviridae) were identified. Bayesian phylogenetic analysis of the Badnavirus (PVBV) using amino acid sequences of the RT/RNA-dependent DNA polymerase region showed the Kenyan sequence (SRF019_MK014483) was closely matched with two Badnavirus viruses: Dracaena mottle virus (DrMV) (YP_610965) and Lucky bamboo bacilliform virus (ABR01170). Phylogenetic analysis of BCMNVA was based on amino acid sequences of the Nib region. The BCMNVA phylogenetic tree resolved two clades identified as clade (I and II). Sequence from this study SRF35_MK014482, clustered within clade I with other Kenyan sequences. Conversely, Bayesian phylogenetic analysis of ALPV was based on nucleotide sequences of the hypothetical protein gene 1 and 2. Three main clades were resolved and identified as clades I–III. The Kenyan sequence from this study (SRF35_MK014481) clustered within clade II, and nested within a sub-clade; comprising of sequences from China and an earlier ALPV sequences from Kenya isolated from maize (MF458892). Our findings support the use of viral metagenomics to reveal the nascent viruses, their viral diversity and evolutionary history of these viruses. The detection of ALPV and PVBV indicate that these viruses have likely been underreported due to the unavailability of diagnostic tools.

Abstract:
The Sport Motivation Scale was firstly developed in French and later translated into English and validated by Pelletier et al. (1995). It is based on the principles of self-determination theory. The present study translated the English version into Portuguese to access and validate it with Brazilian athletes using a sample of 419 athletes (127 women and 292 men) from ten sports. The Brazilian version of the scale showed satisfactory levels of internal consistency and temporal stability over a four-week period. The results of a confirmatory factor analysis partially supported the seven-factor structure. Finally, gender differences were found in all subscales. Taken together, these findings support the use of the Brazilian version of the scale for the assessment of motivation in sport.

Abstract:
A poly(styrene-b-vinylbenzyl triazolylmethyl methyladenine) (PS-b-PVBA) diblock copolymer and a poly(vinylbenzyl triazolylmethyl methylthymine) (PVBT) homopolymer were prepared through a combination of nitroxide-mediated radical polymerizations and click reactions. Strong multiple hydrogen bonding interactions of the A···T binary pairs occurred in the PVBA/PVBT miscible domain of the PS-b-PVBA/PVPT diblock copolymer/homopolymer blend, as evidenced in Fourier transform infrared and 1H nuclear magnetic resonance spectra. The self-assembled lamellar structure of the pure PS-b-PVBA diblock copolymer after thermal annealing was transformed to a cylinder structure after blending with PVBT at lower concentrations and then to a disordered micelle or macrophase structure at higher PVBT concentrations, as revealed by small-angle X-ray scattering and transmission electron microscopy.

Abstract:
Abstract Optimal perturbations are constructed for a two-layer β-plane extension of the Eady model. The surface and interior dynamics is interpreted using the concept of potential vorticity building blocks (PVBs), which are zonally wavelike, vertically confined sheets of quasigeostrophic potential vorticity. The results are compared with the Charney model and with the two-layer Eady model without β. The authors focus particularly on the role of the different growth mechanisms in the optimal perturbation evolution. The optimal perturbations are constructed allowing only one PVB, three PVBs, and finally a discrete equivalent of a continuum of PVBs to be present initially. On the f plane only the PVB at the surface and at the tropopause can be amplified. In the presence of β, however, PVBs influence each other’s growth and propagation at all levels. Compared to the two-layer f-plane model, the inclusion of β slightly reduces the surface growth and propagation speed of all optimal perturbations. Responsible for the reduction are the interior PVBs, which are excited by the initial PVB after initialization. Their joint effect is almost as strong as the effect from the excited tropopause PVB, which is also negative at the surface. If the optimal perturbation is composed of more than one PVB, the Orr mechanism dominates the initial amplification in the entire troposphere. At low levels, the interaction between the surface PVB and the interior tropospheric PVBs (in particular those near the critical level) takes over after about half a day, whereas the interaction between the tropopause PVB and the interior PVBs is responsible for the main amplification in the upper troposphere. In all cases in which more than one PVB is used, the growing normal mode configuration is not reached at optimization time.

Abstract:
Introduction. The article discusses increasing the intensity of light incident on the surface of a photovoltaic battery (PVB) based on semiconductor solar battery, methods of cooling the PVB and protecting the surface from contamination have been investigated. To do this, the PVB is the planes that reflect light to the long sides, and a polycarbonate collector with a parallel channel on the back, this device looks like a photovoltaic-thermal battery (PVT). The article presents the results of the study of electrical and thermal parameters of PVT when changing (increasing) the intensity of solar radiation using reflective planes and cooling by means of a collector. The effects of cold water temperature, environmental characteristics, and atmospheric dust on PVT efficiency have been studied. Research methods and materials. The experiment compared the power of ordinary PVB, collector PVT, and PVTs with reflective planes and collectors. The temperature of the hot water in the collector PVT and the reflective planes and in the PVT with the collector is compared. Experiments have also been carried out to protect the surface of the PVB from dust. Initial measurements were made using PVBs with the same electrical parameters. PVBs are set horizontally, one of which is closed with a lid during the day. In the next experiment, it was studied that the degree of contamination of PVBs depends on the angle of installation. Two of them are horizontal, and the other three are at angles of 300, 450 and 600, respectively. Results and discussions. According to the measurement results, ordinary PVBs, PVBs with collector reflectors and PVTs with collectors have the highest electric power. The difference between the PVB with the collector and the reflection planes and the hot water outlet from the PVT with the collector was 200C. It was determined that the hot water temperature would not exceed 40°C in the absence of reflective planes. Besides, most of the dust on the surface of the PVB falls at night and the level of contamination of the PVB for the city of Termez has been determined. PVBs installed at different slope angles were tested for PVBs installed below 450 with moderate levels of contamination and high electrical parameters. Conclusion. The PVT was found to produce 1,5-1,6 times more electricity in the southern regions of the country than the traditional PVB. It has been shown that hot water can be obtained at temperatures above 40ºC in winter. Research and experiments conducted in the conditions of Termez have shown that it is possible to get the necessary amount of electricity and hot water throughout the year to create good conditions in a rural home. Besides, at night the surface of the PVBs was closed to prevent contamination.

Abstract:
Abstract Background: Regional anesthesia improves postoperative analgesia and enhances quality of recovery (QoR) after ambulatory surgery. This randomized, double-blinded, parallel-group, placebo-controlled trial examines the effects of multilevel ultrasound-guided paravertebral blocks (PVBs) and total intravenous anesthesia on QoR after ambulatory breast tumor resection. Methods: Sixty-six women were randomized to standardized general anesthesia (control group) or PVBs and propofol-based total intravenous anesthesia (PVB group). The PVB group received T1–T5 PVBs with 5 ml of 0.5% ropivacaine per level, whereas the control group received sham subcutaneous injections. Postoperative QoR was designated as the primary outcome. The 29-item ambulatory QoR tool was administered in the preadmission clinic, before discharge, and on postoperative days 2, 4, and 7. Secondary outcomes included block success, pain scores, intra- and postoperative morphine consumption, time to rescue analgesia, incidence of nausea and vomiting, and hospital discharge time. Results: Data from sixty-four patients were analyzed. The PVB group had higher QoR scores than control group upon discharge (146 vs. 131; P < 0.0001) and on postoperative day 2 (145 vs. 135; P = 0.013); improvements beyond postoperative day 2 lacked statistical significance. None of the PVB group patients required conversion to inhalation gas–based general anesthesia or experienced block-related complications. PVB group patients had improved pain scores on postanesthesia care unit admission and discharge, hospital discharge, and postoperative day 2; their intraoperative morphine consumption, incidence of nausea and vomiting, and discharge time were also reduced. Conclusion: Combining multilevel PVBs with total intravenous anesthesia provides reliable anesthesia, improves postoperative analgesia, enhances QoR, and expedites discharge compared with inhalational gas- and opioid-based general anesthesia for ambulatory breast tumor resection.

Abstract:
No laboratório de Análise, Processamento e Reologia de Materiais Poliméricos da Escola Politécnica da USP tem sido estudadas blendas de Poliamida-6 (PA-6) e filme de poli(vinil butiral) (PVB), como uma alternativa para reciclagem do filme de PVB oriundo do processo de separação dos componentes do vidro laminado pós-consumo. As propriedades mecânicas de uma blenda polimérica dependem da sua morfologia e, por sua vez, a morfologia depende das propriedades reológicas e da tensão interfacial entre os polímeros formadores da blenda, que para o caso de blendas envolvendo filme de PVB podem mudar em função da concentração de plastificante presente na composição do filme. Apesar da importância do seu conhecimento, a tensão interfacial entre PA-6 e filme de PVB não é conhecida. O presente trabalho teve como objetivo avaliar a tensão superficial do filme de PVB e da PA-6. O método utilizado foi o da gota pendente. Também estudou-se a influência da adição de plastificante na tensão superficial do filme de PVB. Os resultados mostraram que a tensão superficial dos polímeros estudados decresce com o aumento da temperatura (temperatura variando entre 240 e 260ºC). Em particular, para o filme de PVB a entropia de superfície ( (d/dT) ) apresentou um valor acima dos normalmente encontrados para polímeros fundidos. Este comportamento foi atribuído à estabilidade térmica do filme. O filme de PVB utilizado nos ensaios de tensão superficial foi caracterizado por Espectroscopia no Infravermelho (FTIR), Espectroscopia no Ultravioleta/Visível (UV-VIS), Espectroscopia Eletrônica para Análise Química (ESCA) e Análise Termogravimétrica (TG). Os resultados obtidos comprovaram que há mudanças na estrutura do PVB durante sua exposição a temperaturas elevadas, por longo período de tempo (condições do ensaio de tensão superficial). Foi observado, primeiramente, a evaporação do plastificante, seguida por perda de grupos polares (-OH, C=O e C-O-C) presentes na estrutura do PVB. A tensão superficial da Poliamida-6 foi determinada para temperaturas de 250 e 260ºC. Os resultados mostraram que a PA-6 manteve-se estável durante os ensaios.
In the Rheology and Polymer Processing Laboratory of Escola Politécnica of the University of São Paulo, Polyamide-6 / poly(vinyl butiral) film blends have been studied as an alternative for the recycling of post-consumption laminated glasses. The mechanical properties of these blends were studied and explained in light of their morphology. The morphology of polymer blends strongly depends on the rheological behavior of the blend and on the interfacial tension between the polymers forming the blend. In the case of Poliamide-6 (PA-6)/poly(vinyl butiral) (PVB) film blends, the interfacial tension depends on the plasticizer concentration present in PVB film. However, to our knowledge neither the PA-6/PVB film interfacial tension nor the surface tension of PVB film at temperatures above softening temperatures have been evaluated. In this work, the surface tension of poly(vinyl butyral) and polyamide was evaluated using the pendant drop method. Also it was tried to evaluate the surface tension of PVB film as a function of plasticizer content. The surface tension values obtained were in the same range as the ones obtained for other molten polymers: the surface tension decreases with increasing temperature (for temperatures ranging from 240 to 260°C). However, the value of PVB film surface entropy ((d/dT) where is the surface tension and T is the temperature) was much larger than values reported for other molten polymers. This result was attributed to thermal stability of PVB film during the surface tension measurement. The drops of PVB film after surface tension analysis were examined for any change in their functional groups using infrared spectroscopy (FITIR), ultraviolet-visible spectroscopy (UV/VIS), electron spectroscopy for chemical analysis (XPS/ESCA) and thermogravimetric analysis (TG). The results showed that changes in the chemical structure of PVB film occur during surface tension measurement. First, the plasticizer within the PVB film evaporates and, then, the PVB suffers reduction of polar units and creation of C=C bonds. The surface tension of PA-6 was evaluated for temperatures of 250 and 260°C. The PA-6 remained stable during tests.

Abstract:
O objetivo deste trabalho foi descrever a dinâmica não linear das vozes de homens adultos sem queixas vocais por meio dos padrões visuais de dinâmica vocal (PVDV). Participaram 77 homens falantes nativos do português brasileiro com idades entre 20 a 40 anos (média 30 anos ± 5,54 anos). Para análise não linear foi adotado o método de reconstrução do espaço de fase e gerado um gráfico bidimensional a partir de uma rotina desenvolvida no MatLab® 10.0. Este gráfico foi analisado qualitativamente pela técnica dos PVDV que considera três aspectos da configuração: número de laços das órbitas, regularidade e espaçamento dos traçados. Cada aspecto foi classificado em uma escala de 4 a 0, da melhor para a pior configuração. Todos os indivíduos apresentaram qualidade de voz adaptada na variabilidade normal de acordo com os resultados da avaliação perceptivo-auditiva pelo protocolo CAPE-V e da análise acústica pelo programa MDVP-Kay Pentax. A avaliação do protocolo CAPE-V apresentou média de 18,07 mm (± 4,14 mm), no grau geral da vogal /a/. Na avaliação acústica as médias foram de 125,44 Hz (± 20,78 Hz) para F0; 0,85% (± 0,64%) para jitter; 3,23% (± 1,75%) para shimmer e 0,13 (± 0,02) para NHR. Os resultados da dinâmica não linear por meio dos PVDV se mostrou com número de laços em grau 4 (85,71% com média de 3,84 ± 0,40), regularidade em grau 3 e 4 (ambos com 40,26% e média de 3,12 ± 0,95) e espaçamento em grau 3 (58,44% e média de 2,95 ± 0,76). Concluiu-se que os PVDV da vogal /a/ de homens adultos brasileiros com vozes adaptadas dentro da variabilidade normal apresentou padrão visual caracterizado em sua maioria por presença de 4 ou mais laços, traçados regulares ou com discretas irregularidades e com espaçamento entre as linhas de médio a pequeno.
This work intended to describe the nonlinear dynamics of voices from adult men without vocal complaints using a qualitative analysis of Vocal Dynamics Visual Pattern (VDVP). 77 men speakers of Brazilian Portuguese, aged between 20-40 years old (mean 30 years ± 5.54 years), participated. For the nonlinear analysis a Phase Space Reconstruction was adopted and a two-dimensional graphic was generated from a routine developed on MatLab® 10.0. This graphic was qualitatively analyzed by a VDVP technique, which considers three aspects of the configuration: orbits loop numbers, regularity and spacing of the traces. Each aspect was classified in a scale ranging from 4 to 0, from the better to the worst configuration. All subjects had voice quality adapted on normal variability according to the results of the perceptual evaluation protocol for CAPE-V and acoustic analysis by the program MDVP Kay-Pentax. The perceptual analysis using CAPE-V protocol showed an average of 18,07 mm (± 4,14 mm), in Overall Severity of vowel /a/. On the acoustic analysis, means of 125,44 Hz (± 20,78 Hz) to F0; 0,85% (± 0,64%) for jitter; 3,23% (± 1,75%) for shimmer and 0,13 (± 0,02) for NHR using MDVP program. The results of nonlinear dynamics through PVDV proved with the number of loops in degree 4 (85.71% with a mean of 3.84 ± 0.40), regularity in degree 3 and 4 (both with 40.26% and mean of 3.12 ± 0.95) and degree 3 in spacing (58.44% and mean 2.95 ± 0.76). It was concluded that PVDV of the vowel /a/ of adult males Brazilians with adapted voices on the normal variability presented visual pattern characterized mostly by the presence of 4 or more loops, regular tracings or with discrete irregularities and spacing between lines of medium to small.

Abstract:
O projeto educativo Para Viver de Bem com os Bichos PVBB tem sido aplicado junto a instituições de ensino da Cidade de São Paulo - SP, Brasil e consta de dois módulos: Posse Responsável e Fauna Sinantrópica. O presente estudo foi delineado para analisar a dinâmica deste processo educativo, avaliando o papel dos sujeitos no repasse das informações sobre animais sinantrópicos. Houve o acompanhamento do curso de formação oferecido pelo Centro de Controle de Zoonoses em São Paulo-SP-Brasil, com avaliação dos conteúdos apreendidos pelos multiplicadores e da ação de duas multiplicadoras, professores, alunos e responsáveis em uma unidade de ensino. Foram utilizados questionários de auto-preenchimento, com questões abertas para a análise de conteúdos que após a categorização foram submetidos ao teste de McNemar e concordância kappa. Questões semi-abertas foram utilizadas para caracterizar os grupos sociais homogêneos. A análise de correspondência foi utilizada para estabelecer relações entre respostas e grupos sociais homogêneos. Constatou-se que a implementação do PVBB contribui para a melhoria do grau de conhecimento dos multiplicadores sobre fauna sinantrópica; entretanto a participação no curso do CCZ. A participação dos multiplicadores no curso não foi suficiente para instrumentá-los para o repasse de conteúdos do projeto e de informações técnicas em sua unidade de ensino. Os professores contribuíram no repasse de informações aos alunos dentro das possibilidades que lhes foram oferecidas. Não houve impacto significativo no repasse de informações dos alunos aos seus responsáveis entretanto é interessante observar que, quando da sua existência, este repasse variou nos grupos sociais homogêneos detectados e na condição de haver oportunidade de diálogo em casa.A utilização da agregação das famílias dos sujeitos, em grupos sociais homogêneos, permitiu avaliar a inserção social dos mesmos.A análise feita com a utilização dos grupos sociais homogêneos permitiu avaliar tendências de associações diferenciadas entre os GSH e as respostas citadas pelos responsáveis.
The educative project How to live well with the animals has been applied to educational institutions in the city of São Paulo SP Brazil and has two modules: responsible pets ownership and the other synanthropic fauna. The current study was written to analyze the dynamics of the educational process, evaluating this research subjects in the role of re-passing the information about synanthropic animals. The course offered by the Municipal Center of Zoonosis Control (CCZ), in São Paulo (SP), is offered to multiplier teachers. This course was accompanied and the taught topics to the multipliers were evaluated by applying a self-filling-questionnaire, before and after the course. The teaching action on this taught topics, was accompanied in the school where two multipliers worked. The taught topics were evaluated in the same way again, but considering the teachers, who had received information from the two multipliers, and the children, who studied in the school, and these childrens parents or tutors. The self-filling-questionnaire was composed of free open answers in order to evaluate the taught topics. The topics were statistically studied by McNemar and Kappa concordance test. Another questionnaire with part-closed questions was used to study the social insertion which was studied by the Social Homogeneous Group (SHG) methodology. The correspondence analysis ANACOR-was used to study relations among the SHG and the taught points. The study indicated that PVBB project increases multipliers information about synanthropic animal, but the multiplier could not act on re-passing the information and technical taught to the teachers in the school. The participation of the multipliers in the course was not sufficient for preparing them to act in this way. According to the possibilities the teachers could re-pass part of the topics with their students. There was no sigificative impact on the students action of re-passing the information to their parents or tutors, but it was interesting to observe that the re-passing actions was different according to the homogeneous social group, and the possibility of dialogue between the child and the familiars. The use of SHG methodology could evaluate the social insertion and different association tendencies between the SHG and the answers written by the parents and tutors.

Abstract:
A vasta gama de sistemas poliméricos classificados como blendas tem sido alvo crescente no meio acadêmico e científico. A possibilidade de obtenção de propriedades combinadas e múltiplas, associada a incorporações de blendas poliméricas, enriquece a condição de pesquisa abrindo assim uma extensa área de atuação. Neste trabalho foi proposto o estudo de mistura de composto de poli (cloreto de vinila) plastificado com resíduo de poli (vinil butiral), proveniente de laminados para produção de para-brisas da indústria automotiva, bem como a investigação do efeito da irradiação gama com dose absorvida de 25 kGy, 30 kGy e 40 kGy, controlado com uso de dosímetro de PMMA e taxa de dose equivalente de 0-10 kGy.h-1. Foram analisadas variações das propriedades mecânicas e térmicas das amostras antes e após exposição à radiação gama. As formulações foram constituídas em diferentes concentrações: composto de PVC-C, resíduo de PVB-R, PVC-C/PVB-R 90/10, PVC-C/PVB-R 50/50 e PVC-R/PVB-R 50/50. O composto de poli (cloreto de vinila) foi formulado e aditivado, apresentando comportamento de um elastômero termoplástico, produto flexível. Foram incorporadas aparas moídas de poli (vinil butiral), provenientes de laminados para produção de para-brisas. Ambos os materiais foram incorporados em extrusora granuladora tipo rosca simples e submetidos ao processo de calandragem para efetivação da mistura e formação de mantas plásticas. As mantas foram irradiadas em um reator multipropósito de 60Co e caracterizadas para verificação das propriedades mecânicas e térmicas. Para tanto, as blendas após exposição à radiação gama apresentaram propriedades mecânicas e térmicas intermediarias as propriedades dos seus componentes, mostrando-se um material resistente e de baixo custo. Por meio da microscopia eletrônica de varredura obteve uma redução nos vasos interfaciais mostrando um aumento na capacidade de percolação do PVB na matriz de PVC, favorecendo suas propriedades físicas.
The wide range of polymer systems classified as blends has been increasingly targeted in the academic and scientific milieu. The possibility of obtaining multiple and combined properties, combined with the incorporation of polymer blends, enriches the research condition, thus opening up an extensive area of performance. In this work the study of the poly (vinyl butyral) plasticized polyvinyl chloride mixture from laminates for automotive windshield production was investigated, as well as the investigation of the effect of gamma irradiation with absorbed dose of 25 kGy, 30 kGy and 40 kGy, controlled with use of PMMA dosimeter and equivalent dose rate of 0-10 kGy.h-1. Variations of the mechanical and thermal properties of the samples were analyzed before and after exposure to gamma radiation. The formulations were constituted in different concentrations: PVC-C compound, PVB-R residue, PVC-C/PVB-R 90/10, PVC-C/PVB-R 50/50 and PVC-R/PVB-R 50/50. The polyvinyl chloride compound was formulated and added, exhibiting the behavior of a thermoplastic elastomer, a flexible product. Poly (vinyl butyral) ground chips were produced from laminates for the production of windshields. Both materials were incorporated in a single-thread granulator extruder and submitted to the calendering process to effect the mixing and formation of plastic blankets. The blankets were irradiated in a 60Co multipurpose reactor and characterized for verification of mechanical and thermal properties. In order to do so, the blends after exposure to gamma radiation presented mechanical properties and intermediate thermal properties of their components, showing a resistant material and low cost. By means of the scanning electron microscopy it obtained a reduction in the interfacial vessels showing an increase in the percolation capacity of the PVB in the PVC matrix, favoring its physical properties.

Abstract:
Soot is a combustion generated pollutant that is both a direct risk to human health and a contributing source to global environmental change. Soot can also be a controlling factor in heat transfer inside combustion systems. Thus there is a growing interest in being able to measure soot and understand its production in practical, turbulent combustion environments. Therefore, the specific objectives of this research work were: (1) developing a way to measure velocity of sooty regions that is compatible with existing methods for measuring temporally and spatially resolved soot concentration fields and (2) using these methods to make quantitative measurements of soot in an unsteady, turbulent-like combustor. The Particle Vaporization Velocimetry (PVV) technique was developed and is compatible with Laser Induced Incandescence (LII), a soot concentration measurement approach. PVV is a flow tagging approach, where a high intensity laser (~2-3 J/cm2) is used to vaporize a small region in the soot field. This approach was demonstrated to produce a long lasting and easily readable flow tag that allows for velocity measurements over a wide range of velocities. LII proved to be the best method for detection the motion of the tag after a fixed delay. PVV and LII were used to measure velocity and two-dimensional soot concentration fields in an acoustically excited burner. In addition, images of soot luminosity were obtained. Both laminar and transitional acetylene diffusion flames were studied. The results reveal that strong acoustic forcing can significantly reduce total flame soot, as well as maximum soot concentrations, while simultaneously increasing the average soot temperature. The influence of acoustically generated vortices on soot formation was studied, and soot and products mixture mostly likely dominant high soot concentration regions. Eventually, these mixtures will be propagated downstream and oxidized as a diffusion flame.

Abstract:
Pedestrian protection performance becomes more and more in focus for the car manufactures and systems to reduce injury risk are under development. A wider understanding of both the present and the future windscreen performance in free moving headform testing is needed to optimize these systems. The purpose of this thesis was therefore to learn and understand windscreen behaviour when subjected to head impact and to gain knowledge of CAE status for head impact in windscreens from a pedestrian point of view. A literature review concluded that there are different ways to model a windscreen. It was found that the computer material models for laminated windscreen glass were not capable of fully representing the behaviour of this material under all impact conditions, particularly the non-linear behaviour after fracture or failure. Experimental testing on three different windscreen models, with a free moving headform in a horizontal impactor, has been performed. Test set up was according to Euro NCAP pedestrian testing protocol and three different windscreen angles were tested. The parameter investigated was curvature and HIC and deformation depth on the windscreen were used as evaluation tools. Deformation was measured with a laser positioned behind the windscreen at impact. Film analysis and integration of headform accelerations were used as comparison. The testing concludes that different curvature alone will not have a big influence on HIC and deformation.   Keywords: PVB laminated windscreen, pedestrian, impact, free moving headform

Full text
Abstract:
Bacterial infections are becoming progressively more difficult to treat due to antibiotic resistance and the decreasing rate at which new antibiotics are brought to market. The Turos laboratory has attempted to tackle this problem for the last 15 years with the discovery of N-thiolated β-lactams leading to the design of polyacrylate nanoparticles to deliver these and other drugs. Chapter 1 discusses many reported instances of utilizing different types of polymeric nanoparticles to deliver antibiotics. Poly(lactic-co-glycolic acid) (PLGA), poly(alkyl cyanoacrylate) (PACA), poly(styrene-co-butylacrylate), and chitosan are the main polymers used to make nanoparticles. Chapter 2 describes the synthesis, antibacterial activity, and mechanism of action of N-acyl ciprofloxacins, which have demonstrated in vitro bioactivity against Staphyloccocus aureus, methicillin-resistant Staphylococcus aureus, Bacillus anthracis, Enterococcus faecalis, Bartonella, and E. coli. Antimicrobial activity was found to diminish with increasingly lipophilic acyl groups of the derivatives. The N-acyl ciprofloxacins were found to utilize the same mechanism of action as the parent drug, ciprofloxacin, however, several exhibited lower mutation frequencies. Chapter 3 discusses the use of the N-acyl ciprofloxacins as probes for experimentation on the poly(vinyl benzoate) nanoparticles. These compounds were incorporated into poly(vinyl benzoate) nanoparticles, also designed in the Turos laboratory, to determine the effects of the lipophilic acyl groups on drug loading and drug release. N-acyl ciprofloxacins with higher lipophilicities (predicted logP values) experienced higher drug loading than the less lipophilic counterparts. However, the nanoparticles were unable to release large amounts of entrapped drug. N-acyl ciprofloxacins with increased hydrophilicity were found to either not be incorporated at all, or in incredibly small amounts. Drug release studies of these drugs indicate that possible the hydrophobic compounds that were associated with the nanoparticles were done so via adsorption onto the surface resulting in a burst release of drug. The work is concluded in Chapter 4, followed by experimental procedures and spectral data in Chapters 5 and 6.

Abstract:
Belgium and the Netherlands are fertile ground for radical right parties, including the Flemish Bloc and its successor Flemish Interest (VB), and the List Pim Fortuyn (LPF) and the later Party for Freedom (PVV) in the Netherlands. The LPF presented a mix of anti-immigrant and anti-elitist positions; the PVV was strict on immigration and against European integration; the VB was a nationalist/regionalist party that became successful only after adopting the anti-immigration issue. The LPF showed how a successful but badly organized party can both rise and fall quickly. The PVV shows that a strong leader can establish an electorally successful party that is less effective politically, with an uncertain future because of its dependency on the leader. The VB shows that a party that connects with the electorate’s “demands” can have a series of good election results without having direct policy effects and can be vulnerable to more effective competitors.

Full text
Abstract:
Pressure vessel burst (PVB) explosions are credible explosion hazards at a number of chemical processing and petroleum refining facilities. PVBs can present both blast and fragment hazards. Blast prediction methods specific to spherical PVBs were first developed in the 1970s and revised blast curves were subsequently published. The directional effects from non-spherical PVBs were recently investigated by the authors, resulting in correlations for blast overpressure and impulse for a range of vessel geometries and burst conditions. The existing blast charts coupled with these correlations provide a well-defined blast prediction method for PVBs. When a PVB blast wave propagates through an enclosure opening (e.g., window or door), the result is an infiltrated blast wave which will propagate downstream into the enclosure. This paper addresses the infiltration of a PVB blast wave through an opening on a wall. The properties of an infiltrated blast wave depend primarily on the incident blast wave peak pressure, positive phase duration and the opening size. The purpose of the work described in this paper is to introduce an equivalent explosion source, characterized by these three parameters, so that the infiltrated PVB blast loads can be evaluated based on the equivalent source and existing blast curves.

Abstract:
Pressure vessel burst (PVB) is an explosion scenario commonly encountered at chemical processing facilities. PVBs pose both blast and fragmentation hazards. Blast prediction methods specific to PVBs were first developed in the 1970s and revised blast curves were published in 1995. The published blast curves were developed for spherical vessel bursts. However, most pressure vessels are cylindrical rather than spherical. The blast wave originating from a cylindrical PVB is not spherical (i.e., as with a spherical vessel). Rather, the blast to the sides of a cylindrical vessel is stronger than on the ends, creating non-spherical pressure contours, particularly near the vessel. The cylindrical vessel directional blast effect has recently been investigated by the authors, resulting in a correlation to account for the directional effects. However, it was assumed in the prior work that the vessel was at ground level. This paper extends the prior work to elevated PVBs. Both elevated spherical and cylindrical PVBs are examined to provide new correlations for blast overpressure and impulse for a range of vessel geometries and burst conditions.

Full text
Abstract:
Pressure vessel burst (PVB) is a class of explosion for which there are hazards at virtually all chemical processing facilities. PVBs present both airblast and fragmentation hazards. Blast prediction methods specific to PVBs were first developed in the 1970s and revised blast curves were published in 1995. The published blast curves were developed for spherical vessel bursts, whereas most pressure vessels in use in industry are cylindrical. Blast effects around a bursting cylindrical vessel are not uniform as with a spherical vessel. The blast to the side of a cylindrical vessel is stronger than off the ends, creating non-circular pressure contours. The directional effects diminish with distance as the expanding shock wave approaches a spherical shape. A correlation was developed in the 1970s to account for directional effects using high explosive test data, the best available resource at the time. Like all test programs, pressure transducers extended to limited distances from the explosive charge, yet the data are often extrapolated to a far greater distance. This paper presents the results of recent work on directional effects specific to bursting cylindrical pressure vessels and provides new correlations for blast overpressure and impulse for a range of vessel geometries and burst conditions. The results can be used to predict the airblast hazards from cylindrical PVBs over the range of standoff distances for which directional effects exist.

Full text
Abstract:
Abstract Blast waves from explosion sources such as a pressure vessel burst (PVB) exhibit both positive and negative phases, and the relative magnitude of the positive and negative phases is a function of standoff distance from the explosion source to the target of interest. When an incident blast wave reaches a target building, the blast wave will be reflected off the front wall (i.e., that facing the blast source). Both the blast wave positive and negative phases are affected by this reflection process. A fully reflected blast wave would be produced if the incident blast wave reflected off an infinitely tall and wide wall in a normal orientation. However, when an incident blast wave reflects from a facing wall of finite size, rarefaction waves are created at the edges of the wall and roof, which then sweep inward across the wall. The rarefaction waves result in a clearing effect for both the positive and negative phases. Clearing relieves some of the applied positive phase blast load on the reflected wall. However, clearing may either relieve or enhance the applied negative phase blast load, depending on the blast wave profile and the wall dimensions. This paper focuses on the determination of negative phase clearing as a function of blast wave and structure parameters. Blast load adjustment factors (i.e., ratio of cleared to fully reflected blast loads) are introduced to characterize blast clearing as a function of these parameters. The purpose of the evaluation described in this paper was to generate a database of the blast clearing for engineering modeling of blast-structure interaction.

Full text
Abstract:
Abstract A pressure vessel burst (PVB) is an explosion scenario commonly encountered at chemical processing and petroleum refining facilities. Existing methodologies are available to predict the blast loads resulting from a spherical or cylindrical PVB source, with the PVB source either at grade or at an elevation. In the case of an elevated PVB source, the resulting blast wave will reflect from the ground at an angle. This ground level reflection will result in the formation of a Mach stem at certain angles between the incident blast wave and ground, with the required angles dependent on the blast wave overpressure. The triple point associated with the Mach stem moves upwards as the Mach stem progresses forwards, which can create a region of high blast pressure. This paper focuses on the investigation of a methodology that can be used to determine the high-pressure region generated by the Mach stem, along with the associated blast pressure, as a function of the PVB source elevation and incident blast pressure.

Full text
Abstract:
The Netherlands boasts a wide array of populist Radical Right parties, from the Freedom Party (PVV) and Forum for Democracy (FvD) to Correct Alternative 2021 (JA21). To complicate matters further, the left-wing Socialist Party (SP) is also considered a populist party. Mirroring the diversity of responses to the Russian invasion of Ukraine in the rest of Europe, Dutch populist parties have reacted in myriad ways. Whereas the PVV condemned the Russian invasion, the FvD remained highly supportive of Putin. Interestingly, while many European populist Radical Right leaders, following public opinion, pivoted away from support for Russia, the FvD has maintained its support for Putin’s regime throughout 2022. JA21, on the other hand, has followed the non-populist parties, calling for tougher sanctions on Russia. This report maps the diverse positions of the three populist Radical Right parties regarding Russia. However, we also seek to explain why they have chosen such diverse paths. The report focuses on supply-side considerations, such as the impact of the parties’ relative degree of populism, their attaching ideology, and their position in the highly fragmented party system.
