_
In this paper, the hydroelastic response of a NACA0015 composite hydrofoil is studied experimentally and numerically. The foil is made of composite materials with fibers not aligned with the span of the foil, which results in the occurence of a bend-twist coupling in the material. Computations are performed using a partitioned approach. The flow problem is solved using a boundary element method. The structural response of the foil is modelled with two different finite element models. In the first one, the foil is modelled with 2D shell and 3D solid finite elements and in the second model, the foil is modelled with 1D beam finite elements. The experiments are conducted in an open circulation water channel. Hydrodynamic forces and structural displacements are measured for several angles of attack, free stream velocities and submergence depth. This paper shows that the mechanical behaviour of a composite hydrofoil submitted to hydrodynamic loads can be modelled with 1D beam finite elements. This model gives results very similar to a finite element analysis realized with 2D shell and 3D solid finite elements, which are commonly used to model composite structures. The present work also shows that the experimental results can be well predicted by numerical simulations, but it requires a precise modeling of the bend-twist coupling in the materials constituting the foil.

Published: April 2024

Объектом исследования в статье выступает пьеса для актёров и оркестра «Every good boy deserves favour» (в рус. перев. «До-ре-ми-фа-соль-ля-си-Ты-свободы-попроси»), созданная британским драматургом Томом Стоппардом и американским композитором Андре Превеном в 1977 году. Главной идеей пьесы является противостояние тоталитарного государства и личности. В работе раскрываются особенности драматургии и стилистики пьесы в ракурсе воплощения её ведущей тематической линии. Отмечается влияние театра абсурда в драматургии Стоппарда. Особое внимание уделяется специфике сценической постановки, а также музыкальному языку, насыщенному стилевыми аллюзиями и цитатами. Выбор интертекстуальных отсылок, их анализ и интерпретация позволяют утверждать, что музыка становится важным смысловым компонентом всей пьесы, не только отражая главную идею сочинения, но и устанавливая дополнительные смысловые обертоны, раскрывающие судьбу искусства в тоталитарном государстве.
The object of the research in the article is the play for actors and orchestra Every Good Boy Deserves Favour, created by the British playwright Tom Stoppard and the American composer André Previn in 1977. The main idea of the play is the confrontation between a totalitarian state and an individual. The article reveals the features of the drama and style of the play from the perspective of the embodiment of its leading thematic line. The influence of the theater of the absurd in Stoppard’s drama is noted. Special attention is devoted to the specifics of the stage production, as well as the musical language packed with stylistic allusions and quotations. The choice of intertextual references, their analysis and interpretation allow us to assert that music becomes an important semantic component of the whole play, not only reflecting the main idea of the composition, but also establishing additional semantic overtones that reveal the fate of art in a totalitarian state.

Published: April 2024

As Tecnologias de Informação e Comunicação (TIC) foram incorporadas às cidades propiciando novas relações com o espaço urbano. As tecnologias móveis, dispositivos, gadgets e aplicativosque utilizam tecnologias baseadas em localização (LBT) e serviços baseados em localização (LBS) possibilitam que um fluxo intenso de informações seja transformado em uma nova forma de territorialização.A arte contemporânea, entre tradições e identidades uniformizadas pela globalização, tem papel fundamental na construção do imaginário cotidiano neste contínuo processo de urbanização. Esta cultura, lugar de experiências urbanas, constrói cartografias estéticas, como geoanotações e narrativas na cidade. O artista-cidadão, utilizando-se da estética radicante proposta por Bourriaud (2011), transplanta origens, inventa trajetórias, ressignifica-se em suas errâncias.
O entrever da história nas narrativas de Luiz Ruffato
Authors: Paula Júlio César Machado de 
Published: April 2024

Em regra, a expectativa que se tem de uma resenha é que ela esteja associada a algo novo, isto é, ao lançamento recente de um livro, à abertura de uma exposição, ao concerto que ainda ontem fez sua estreia. O texto que ora apresentamos, no entanto, assume o risco de frustrartal expectativa por duas razões: primeiramente, motiva-se não por uma estreia literária, propriamente, mas por uma reedição, a décima primeira,“revista e definitiva”, de Eles eram muitos cavalos, de Luiz Ruffato, obra publicada, originalmente, em 2001; e, além disso, pelo fato de que não trataremos, exatamente, do livro em si, mas das relações que estabelece como conjunto da obra, especialmente, com os cinco volumes que compõem o ciclo narrativo intitulado Inferno Provisório.

Authors: Sethi Nabiea Parveen , Khalil Obaid Ahmad , Ali Shah Syed Asim , Khan Amir 
Published: April 2024

Background: Cardiovascular diseases causes more deaths and disability in developing countries than any other disease in the world, for these diseases, CABG (Coronary artery bypass grafting) and VR (valvular replacement) are the best treatment options, although, these surgeries improve the chances of survival but they may cause chronic post operative musculoskeletal pain. Musculoskeletal pain can arise from different body musculoskeletal structures such as muscles, tendons, ligaments and joints and knowing the exact cause of this musculoskeletal pain is very difficult and challenging. Chronic musculoskeletal pain patients may have different signs of pain and spread of pain to degrees which are related to pain intensity and duration, so in management, it is very important to reduce duration and intensity of pain.
Methods: A cross-sectional survey design was conducted among 199 cardiac patients in Peshawar from both genders, from June 2018-November 2018 among patients at RMI, KTH.,LRH and at other private clinics. Tool used for data collection named as Orebro musculoskeletal pain questionnaire and self- made questionnaire was used in this study.
Results: Patients mean age was 53.49±11.88, 69.8% were males and 30.2% were females. The results showed that most common MSK pain site is upper back 27.6% and most common surgery is CABG. This study analyzed that different surgical procedure through which participants had been undergone. The surgical procedures were categorized into 4 main domains as shown in table 8 and frequency analysis was done which shows that most common surgical procedure is CABG (Coronary artery bypass grafting) 64.3%. The result of this study shows that diagnosis domain descriptive analysis was done to find out the frequency of the present pain conditions of the participants which exhibits that most common pain occurs in the back 27.6% and in the shoulder 25.1%
Conclusion: Results among patients of Peshawar showed that most common surgery performed is CABG while PCI intervention is the next. Most of the patients are suffered from upper back pain while leg pain and cervical pain is not so common.

Background: Chronic inflammation, a factor for high mortality, persists throughout the pregnancy period of women living with human immunodeficiency Virus (HIV).
Aim: To determine whether pregnancy alone or the combined effects of HIV and pregnancy are the sources of the inflammation, this study evaluated the predictive variables for inflammation, lymphocyte ratio (NLR), and Platelet-Lymphocyte Ratio (PLR).
Materials and Methods: A population of 128 women, aged 15-49 years were grouped into 4; Group A- 32 HIV positive and pregnant, Group B- 32 HIV negative and pregnant, Group C- 32 HIV positive not pregnant, Group D- 32 HIV negative not pregnant (control group). Differential white blood cell and platelet count methods were used to determine the neutrophil (N), Lymphocyte (L) and platelet (P) counts. The ratio calculation method was used to derive the NLR and PLR.
Results: NLR was significantly higher for group A (2.62±0.41) compared to groups B (2.25 ± 0.18); C (0.95 ± 0.07); D (1.68 ± 0.19) at p ≤ 0.00. However, the NLR of groups A and B (p ≤ 0.05) were not significantly different, PLR was significantly higher for group A (9.86±1.12) compared to groups B (6.65 ± 1.12); C (5.35 ± 0.47); D (6.34 ± 0.43). There was no significant difference in blood pressure across the groups, significant difference was however observed in their Body Mass Index.
Conclusion: Hence, Inflammation may have been caused by pregnancy alone.
A systematic approach for on‐line identification of second‐order process model from relay feedback test
Authors: Liu Tao , Gao Furong , Wang Youqing 
Published: April 2008

AbstractLow‐order process modeling provides a basis for control system design and on‐line autotuning in process control. A systematic on‐line identification method is proposed in this article to obtain a second‐order‐plus‐dead‐time (SOPDT) model from a single biased/unbiased relay feedback test. The relay response shapes of the three types of SOPDT model, overdamped, critically damped, and underdamped, are first examined and categorized for model structure selection before proceeding with the corresponding parameter identification. Exact expressions of the corresponding limit cycles are derived for assessing process response under relay feedback test. By using the measurable parameters of these limit cycles, the corresponding identification algorithms are subsequently derived in a transparent manner. Two denoising methods are given to cope with measurement noises. Illustrative examples are performed to demonstrate the effectiveness and merits of the proposed identification algorithms. © 2008 American Institute of Chemical Engineers AIChE J, 54, 2008
Process analysis of CO2 capture from flue gas using carbonation/calcination cycles
Authors: Zhen‐shan Li , Ning‐sheng Cai , Croiset Eric 
Published: April 2008

AbstractProcess analysis of CO2 capture from flue gas using Ca‐based carbonation/calcination cycles is presented here. A carbonation/calcination system is composed essentially of two reactors (an absorber and a regenerator) with Ca‐based sorbent circulating between the two reactors (assumed here as fluidized beds). CO2 is, therefore, transferred from the absorber to the regenerator. Because of the endothermicity of the calcination reaction, a certain amount of coal is burned with pure oxygen in the regenerator. Detailed mass balance, heat balance and cost of electricity and CO2 mitigation for the carbonation/calcination cycles with three Ca‐based sorbents in dual fluidized beds were calculated and analyzed to study the effect of the Ca‐based sorbent activity decay on CO2 capture from flue gas. The three sorbents considered were: limestone, dolomite and CaO/Ca12Al14O33 (75/25 wt %) sorbent. All results, including the amount of coal and oxygen required, are presented with respect to the difference in calcium oxide conversion between the absorber and the regenerator, which is an important design parameter. Finally, costs of electricity and CO2 mitigation costs using carbonation/calcination cycles for the three sorbents were estimated. The results indicate that the economics of the carbonation/calcination process compare favorably with competing technologies for capturing CO2. © 2008 American Institute of Chemical Engineers AIChE J, 2008
Surface temperature and time‐dependent measurements of black liquor droplet combustion
Authors: Ip Leong‐Teng , Baxter Larry L. , Mackrory Andrew J. , Tree Dale R. 
Published: April 2008

AbstractBlack liquor droplets, initially 1–3 mm in diameter, were burned while simultaneously measuring surface and internal temperature, mass loss, and diameter to gain insight into the physical processes of single droplet combustion. Data were collected by weighing a droplet hanging on a thermocouple wire within a heated furnace. Two‐color images of the droplet were obtained to determine a surface temperature and particle size. The data suggest that models of droplet combustion should treat drying, devolatilization, and char oxidation as occurring simultaneously, though typically in different regions of the particle. Isothermal models should be avoided as temperature differences in excess of 300 K exist between the surface and interior, with larger gradients along the surface. Droplet swelling increased at lower ambient temperatures, and is greater for softwood than hardwood liquors. Additional unidentified factors also influence swelling, meaning it is still highly unpredictable and may be a function of initial droplet shape, size, and chemical composition. © 2008 American Institute of Chemical Engineers AIChE J, 2008
Mitochondrial DNA and craniofacial covariability of Chad Basin females indicate past population events
Authors: Hájek Martin , Černý Viktor , Brůžek Jaroslav 
Published: April 2008

AbstractThe Chad Basin lies in the middle of the Sudanic African belt between the Sahara and the tropical rain forests. Its present‐day settlement is a result of Holocene climatic changes and human immigrations from different parts of Africa. This study presents a statistical analysis of the relationships of physical features (stature and five main craniofacial measurements) and mitochondrial (mtDNA) haplogroup classifications in a sample of 282 adult individuals belonging to seven populations of different ethno‐linguistic groups living in the Chad Basin. Drawing on the analysis of variance, we identified a female‐specific DNA association between mtDNA haplogroup assignment and facial height. More specifically, the mtDNA haplogroups of East‐African origin occur more frequently in females with relatively longer faces and, conversely, the mtDNA of West‐African origin are found more frequently in females with lower faces. Interestingly, this kind of association is not found in the males of the same populations. Our interpretation refers mainly to population history; we suggest that facial height and mtDNA haplogroup co‐variance in Chad Basin females reflects a long‐term east–west population distribution in the past that made the facial differentiation possible.

AbstractWe report the results of follow‐up analyses of 12 genomic regions showing evidence of linkage in a genome‐wide scan (GWS) of Gypsy families with bipolar affective disorder (BPAD). The Gypsies are a young founder population comprising multiple genetically differentiated sub‐isolates with strong founder effect and limited genetic diversity. The BPAD families belong to a single sub‐isolate and are connected by numerous inter‐marriages, resulting in a super‐pedigree with 181 members. We aimed to re‐assess the positive GWS findings and search for evidence of a founder susceptibility allele after the addition of newly recruited subjects, some changes in diagnostic assignment, and the use of denser genetic maps. Linkage analysis was conducted with SimWalk2, accommodating the full complexity of pedigree structure and using a conservative narrow phenotype definition (BPAD only). Six regions were rejected, while 1p36, 13q31, 17p11, 17q21, 6q24, and 4q31 produced nominally significant results in both the individual families and the super‐pedigree. Haplotypes were reconstructed and joint tests for linkage and association were done for the most promising regions. No common ancestral haplotype was identified by sequencing a strong positional and functional candidate gene (GRM1) and additional STR genotyping in the top GWS region, 6q24. The best supported region was a 12 cM interval on 4q31, also implicated in previous studies, where we obtained significant results in the super‐pedigree using both SimWalk2 (P = 0.004) and joint Pseudomarker analysis of linkage and linkage disequilibrium (P = 0.000056). The size of the region and the characteristics of the Gypsy population make it suitable for LD mapping. © 2008 Wiley‐Liss, Inc.

Published: April 2008

AbstractIn this study, a series of nanocomposite membranes consisted of organic polyimide and organo‐modified clay were successfully prepared by an in situ polymerization through thermal imidization reactions using a dual‐ (i.e., CTAB/melamine) and mono‐organic modifier as swelling agent of clay mineral. A sequential comparative study was performed to investigate the effect of various feeding ratios of dual‐ and mono‐organic modifiers on the physical properties of as‐prepared samples. The as‐synthesized nanocomposite membranes were subsequently characterized by WAXRD and TEM. It should be noted that all the nanocomposite membranes prepared from a dual‐organic modifier system exhibited a better dispersion of silicate layers in PI matrices as compared with that of mono‐organic modifier system. Comparative studies for the effect of various feeding ratios of dual‐ and mono‐organic modifiers on the thermal stability, mechanical strength, molecular barrier properties, and optical clarity of PI‐clay nanocomposite membranes were performed with measurements of TGA, DSC, DMA, GPA, VPA, and UV–visible transmission spectroscopy, respectively. © 2008 Wiley Periodicals, Inc.

Published: April 2008

AbstractSurface of polypropylene (PP) sheets were modified by radiation induced graft polymerization of a mixture of two monomers, a quaternary ammonium salt ([2‐(methacryloyloxy)ethyl]‐trimethyl ammonium chloride) (QAS) and acrylic acid(AA) to control the bacterial adhesion. Electron beam radiation was used to activate PP sheets prior to the grafting reaction. Depth concentration profile of nitrogen on modified PP up to 10 nm was performed by XPS. However, XPS has revealed no significant changes in the concentration profile of nitrogen for the grafted PP prepared under different parameters. Energetic characteristics (Lifshitz‐van der Waals (γLW), electron acceptor (γ+), and electron donor (γ−) components) of these modified surfaces (with different ratio of comonomer mixtures) were calculated by using contact angle measurements. The PP surfaces prepared under one specific ratio of comonomer mixture (AA : QAS) 20 : 40 (M‐4) has been compared with the surfaces modified with 20% AA (AA‐20) and 40% QAS (QAS‐40). The surface charge and isoelectric point have been determined by zeta potential measurements. AA‐20 and comonomer mixture modified PP (M‐4) surfaces exhibit negative charges of −27 and −16, respectively, while QAS‐40 modified PP surfaces show positive charge of +16. The physicochemical properties of Listeria monocytogenes (LM) were obtained by microbial adhesion to solvent method. Finally, adhesion of LM on unmodified and modified PP surfaces was observed by electron microscopy. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008

Published: April 2008

AbstractThis study was performed on cycloolefin materials. These polymers are more and more used in the cosmetic and pharmaceutical fields. Samples were subjected to an electron beam radio‐sterilization. Different irradiation doses ranging from 25 to 150 kGy were used to study the irradiation effect on the structure and properties of the material. In this study, we were mainly interested in additive degradation, and in the modification of polymer thermomechanical properties, as elasticity, glass transition temperature, and swelling ability. Although the modification of the polymer chains was important, effect on thermomechanical properties was quite weak. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008
