Mathematical modeling and analysis of the development of territorial communities
Authors: Bihun Roman , Lytvyn Vasyl , Oleksiv Nazar
Published: July 2021

This article examines the problems of the development of united territorial communities, in particular, unemployment and economic problems. The object of the research is the improvement of territorial communities on the example of the Lviv region (Ukraine). One of the most problematic areas is the fact that communities, in most cases, do not have enough funds to solve economic and other problems.
The study uses the idea of the need to create self-sufficient communities with a sufficient number of financial instruments for their own development. The mathematical model of the decision support system for the development of territorial communities using the agro-industrial sector is also considered. An important step in building a mathematical model of the agro-industrial complex is taking into account the specifics of agriculture. The paper considers a mathematical model of linear and multifactorial regression, which describes the relationship between the amount of resources expended and the volume of output. Since the processes in the economy and production processes in agriculture are complex, it is difficult to describe them using only linear deterministic models. A common case is when task variables take some discrete values or values from a specific one. This situation makes the search difficult. To build a mathematical model for the development of territorial communities and study the fact that the development of agro-industry will improve the overall economic situation of the territorial community, correlation and regression analysis, the Farrar-Glauber method and the method of least squares are used. Thanks to the listed instruments, the statement is formed that the regulation of key factors of economic indicators of the agricultural sector can positively affect the growth of the economic component of territorial communities. The created mathematical model clearly forms the conclusion that agriculture in local communities can become an economic engine of community development, taking into account regional conditions.
Research of ANSYS Autodyn capabilities in evaluating the landmine blast resistance of specialized armored vehicles
Authors: Shlyk Sergii
Published: July 2021

The object of research is the processes of pulse explosive loading in an explicit formulation for simulation of complex nonlinear dynamics of solids, gases, and their interactions. One of the most problematic areas of modern studies of nonlinear dynamic loads of materials using a numerical analysis is that such studies usually do not take into account the characteristic transition of the stationary deformation zone of the loaded material to the unsteady one and the front pressure and shockwave velocity variation by time.
The work is aimed at developing a mathematical model of a pulsed load of materials by a shockwave, developing a mathematical apparatus for calculating the parameters of a shockwave, creating analytical dependences of the interaction of a shockwave with a loaded surface. A study of dynamic explosive loading using software based on an explicit method for solving the equations of continuum mechanics is proposed.
In this work, the stress-state equation at a point of the material under pulsed load conditions was further developed, methods for determining the principal stresses and the invariant of the stress tensor, taking into account the pulsed nature of the load, were established. The character of the behavior of the shockwave formed as a result of the detonation of the explosive has been established. Analytical dependences of the interaction of a shockwave with a loaded surface are compiled. A mathematical apparatus has been developed for calculating such parameters of the shockwave as the detonation front pressure and its change in time and the velocity of the shockwave at the moment when it reaches the surface.
Mathematical dependences have been developed and proposed, which, in contrast to the existing ones, make it possible to determine the current values of stresses and strains passing through the points of the actual stress curve, as well as the intensity of stresses and strains under pulse loading of metals.
On the basis of theoretical and experimental studies of the parameters of body material deformation under the action of explosive loading, the mechanisms of destruction of the KrAZ «Shrek» and KrAZ «Fiona» (Ukraine) specialized armored vehicles body were clarified to establish the compliance of the declared landmine resistance of vehicles with the STANAG 4569 standardization agreement.
The influence of the rigidity of mining security structures on the stability of side rocks in the coal-rock massif
Authors: Korol Anton
Published: July 2021

The object of research is the processes of controlling the state of side rocks to prevent the collapse of the stratified rock strata in the coal-rock massif containing the workings. The studies carried out made it possible to establish the influence of the rigidity of the guard structures of mine workings on the stability of side rocks in the coal-rock massif. It is proved that as a result of the action of an external compressive load on the supporting lateral rocks, the structure, in the form of a model of bunches made of wooden posts, increases its rigidity until the destruction of the security structure. After that, there is an increase in the convergence of side rocks and their destruction. The change in the stiffness of the crushed rock in the filling massif model, which is used to support the lateral rocks, occurs as a result of the compaction of the original material. This is due to repackaging of crushed rock fractions of different sizes and its additional grinding. As a result of this interaction of the side rocks with the filling massif, the integrity of the roof and soil is ensured and convergence is limited. To assess the stability of side rocks, it is proposed to use a dimensionless stress concentration factor k. This coefficient takes into account the rigidity of the guard structures of the mine workings and the flexural rigidity of the side rocks. It was found that when the values of the coefficient k are close to zero (k→0), there is a loss of stability of the guard structures of mine workings and the destruction of side rocks in the coal-rock massif. The preservation of the integrity of the side rocks and the stability of security structures is ensured at values of k>0.1, which corresponds to the parameters of the pliable supporting structures. Most favorably on the condition of side rocks in the coal-rock massif is influenced by the method of backing up the mined-out space of crushed rock. The use of this method excludes the collapse of side rocks. When solving the problem of stability of mine workings at the stage of making technical decisions, it is necessary to predetermine the issues of rigidity of security structures with deformation characteristics of side rocks.

Deep wound infection of the anterior chest wall tissues in patients after transsternal cardiac surgery despite intensive developments in surgical techniques and improvement of antibacterial chemotherapy, remains a genuine concern worldwide [1]. The incidence of this complication in the general population ranges from 0.5 to 4% [2, 3]. Despite developed approaches in the treatment of cardiac surgery patients, the treatment of deep sternal wound infection and surrounding tissues following a heart transplantation still remains a rather serious and pressing challenge. This paper presents a clinical observation of a heart transplant recipient, complicated by deep postoperative wound infection. The strategy of staged surgical treatment of sternal osteomyelitis consisted of surgical wound debridement, local wound debridement with vacuum dressings, and reconstructive surgery at the final stage (sternal reosteosynthesis, plasty of the anterior chest wall wound with displaced skin and fascial flaps).

To date, liver transplantation remains the only effective treatment for patients with cirrhosis. Due to lack of other effective, alternative therapeutic methods, the search and development of new treatment technologies is problem number one. The development of cellular technologies is promising for use in clinical practice. Using this observation as an example, the safety and efficacy of cell therapy technology for prolonged stay on the liver transplant waiting list by a patient with cirrhosis is shown. After intraportal injection of autologous bone marrow-derived mononuclear cells, liver cirrhosis stabilized on the CTP and MELD-Na scales for 22 months of observation, which allowed the patient to wait for an organ and successfully undergo liver transplantation.
UM ESTUDO DE PREPOSIÇÕES EM CONTEXTO DE CONSTRUÇÕES DE VERBO AUXILIAR
Authors: COELHO Sueli Maria
Published: July 2021

RESUMO Neste artigo, descrevemos e analisamos construções da língua portuguesa formadas por [verbo auxiliar + preposição + infinitivo], que são aqui abordadas num viés pancrônico, pautado numa concepção cognitivista e multissistêmica de língua(gem). Nosso objetivo maior consiste em explicar por que, em algumas dessas construções, a preposição tende a ser apagada, sobretudo em contextos de oralidade, sem que tal apagamento resulte em prejuízo para a boa formação da sentença, enquanto em outras o liame preposicional deve obrigatoriamente se interpor entre o verbo auxiliar e a forma nominal de infinitivo, sob pena de se comprometer a boa formação do composto. No entorno dessa questão maior, buscamos ainda descrever que tipo de preposição ocorre nessas construções, a correlação entre o tipo de preposição e a função gramatical (tempo, aspecto, modalidade) codificada pela construção, além de identificar fatores condicionantes da presença da preposição nesses contextos. Os resultados obtidos acusam que apenas as preposições A, DE, PARA e POR podem ocorrer nesses contextos e que elas são herdadas do contexto de reanálise da construção, majoritariamente ligado a um ambiente sintático de finalidade. A opcionalidade da preposição no contexto é restrita à preposição A e condicionada por uma imbricação de fatores de natureza fonológica, prosódica e semântica.

ABSTRACT The success of the integrated crop-livestock system depends on the correct pasture management, particularly regarding nitrogen fertilization and grazing intensity. The objective of this study was to evaluate the total production of forage and the proportion of the botanical and structural components of black oat and annual ryegrass mixture. The experimental design was randomized blocks with three replicates and the treatments were arranged in a three-factorial scheme: seed inoculation (with and without Azospirillum brasilense inoculation), grazing management (conventional grazing, where the animals were kept in pasture with no control of pasture height; 30, 20 and 10 cm at the end of grazing, and a control without grazing), and nitrogen fertilization (0, 50 and 100 kg nitrogen ha-1). In treatments with pasture heights where grazing ended at 30, 20 and 10 cm, the height was monitored and biomass was collected when the animals entered and exited the plots. Manual separation of the components was used to determine the dry mass of green leaves, stems, senescent material and inflorescence. Total dry mass production was obtained based on the initial forage mass plus the daily accumulation rates. The proportion of structural components varied according to the different grazing managements, nitrogen doses and inoculation with Azospirillum brasilense. Biomass production of black oat and ryegrass mixture was increased by nitrogen application and Azospirillum brasilense inoculation.

Published: July 2021

ABSTRACT Technologies that use rhizobacteria to promote plant growth are increasing in agriculture, results have shown improvements in soil quality, increases in productivity, and decreases in the use of synthetic inputs, The objective of work was to characterize bacterial isolates regarding their biological activity and growth promotion of soybean plants grown in a controlled environment. Fifteen bacteria were isolated from soils with continuous use of biological fertilizer. They were evaluated for enzymes production (amylase and protease), nitrogen fixation, antagonistic activity to phytopathogenic fungi, and indoleacetic acid (IAA) production, Soybean seeds were inoculated with bacterial isolates in a greenhouse and evaluated for plant development and soil chemical attributes. The results showed that 8 of the 15 isolates presented production of amylase, protease, or both and 4 isolates presented nitrogen-fixing capacity. The percentage of isolates with high or moderate inhibitory action against the fungi Sclerotinia sclerotiorum, Macrophomina phaseolina, and Fusarium solani were 73.3%, 66.6%, and 73.3%, respectively. The IAA production varied from 8.56 to 31.33 µg mL-1 (5 isolates had low, 6 had moderate, and 4 had high production). The soybean development was significantly higher in 80% of the treatments with inoculation with bacterial isolates. Five bacterial isolates effectively present all characteristics for use as inoculant (biofertilizer) to promote the development of soybean plants.

ABSTRACT Stress caused by soil water deficit has been one of the main factors that inhibit plant growth. The knowledge of the factors related to the behavior of weed species under water stress conditions can contribute to the elaboration of effective control strategies. Two experiments were carried out to evaluate the effects of the degree and duration of water deficit on physiological and growth indicators of two weed species (Bidens pilosa L. and Bidens subalternans DC.). The stress degree was simulated by four soil moisture: 100, 75, 50, 25% of total soil capacity. The water deficit duration was evaluated by five intervals of water supply: 0, 1, 2, 3, 4, 5, and 6 days. The experiments were carried out in a randomized complete block design with six replicates. The evaluated variables were: the photosynthetic rate (A; μmol CO2 m-2), stomatal conductance (gs; μmol H2O m-2 s-1), transpiration (E; mmol H2O m-2 s-1), number of leaves per plant, and dry matter of the roots, stems, leaves, and total. The results showed that the species of B. pilosa and B. subalternans tolerate low water availability conditions. Low stomatal opening and loss of leaves are mechanisms that ensure the survival of Bidens plants to the water deficit. However, water stress close to 25% of field capacity caused the death of species. The B. subalternans had higher sensitivity to the water deficit, showing a lower dry matter of leaf, stem, and root than B. pilosa.

Published: July 2021

Resumo O saneamento básico inadequado pode ocasionar uma série de doenças endêmicas e epidêmicas. O objetivo é analisar a influência da Política Municipal de Saneamento Básico (PMSB) na ocorrência de doenças relacionadas ao saneamento básico inadequado nos municípios brasileiros. Utilizando dados da Pesquisa de Informações Básicas Municipais (MUNIC) de 2017, a análise empírica é dividida em duas etapas. Primeiro, utiliza-se o modelo probit espacial para identificar se a presença da PMSB influencia a probabilidade dos municípios apresentarem doenças. Segundo, utiliza-se o modelo logit para verificar as chances de ocorrência de doenças, levando em consideração o tipo de cluster espacial de PMSB que os municípios pertencem. Os resultados da primeira etapa detectaram a presença de dependência espacial e não permitem afirmar que possuir a PMSB diminui a probabilidade de ocorrência de doenças. Os resultados da segunda etapa mostraram que há uma diminuição das chances de ocorrência de doenças em municípios que pertencem a clusters do tipo HH (municípios com PMSB, cercados por municípios com PMSB) e LH (municípios sem PMSB, cercados por municípios com PMSB). Conclui-se que para a PMSB ser efetiva na redução da ocorrência de doenças, ela deve ser planejada em um contexto espacial mais amplo que os limites municipais.

Published: July 2021

Abstract The main objective of this study was to identify and quantify inappropriate disposal of construction and demolition waste (CDW) in Cabo Frio, Brazil. The municipality has areas of environmental preservation and suffers significant environmental impacts due to the large flow of tourists and the inappropriate disposal of CDW. Data collection, carried out from June to September-2019, covered eighteen neighborhoods. 179 inadequate CDW disposal points were detected corresponding to a volume of approximately 448.75m3. The results were grouped by neighbourhood, kind of disposal place and CDW type. Pareto diagrams were also presented to help define priority neighborhoods for inappropriate disposal reducing actions. There was inappropriate disposal in areas of ecological, landscape or scientific interest, over drainage places, on public roads or sidewalks, and on vacant lots. Besides analysing the disposal characteristics and suggesting actions to solve the problem, a methodology for surveying of inappropriate disposal of CDW was proposed, including a method for the rough calculation of CDW volumes. The development of a smartphone application is another contribution that can facilitate data registration and assist decision making. Although the research focuses on a Brazilian municipality, the same work can be expanded to other municipalities in the world.
Movilidad residencial y social en barrios populares consolidados en Bogotá
Authors: Sierra Angélica Camargo , Solano Alex Smith Araque
Published: July 2021

Resumen En este texto se estudia la movilidad social y residencial de los propietarios de viviendas en algunos barrios populares consolidados en Bogotá. La trayectoria laboral y residencial del propietario antes de su llegada a la vivienda actual permite acercarse a la movilidad social ocupacional intrageneracional. Mediante el enfoque biográfico se analizaron 341 encuestas a propietarios en cinco barrios populares consolidados. Los datos permiten concluir que tienen trayectorias estáticas, tanto a nivel ocupacional como residencial. Las razones explicativas de la inmovilidad ocupacional y residencial se encuentran en aspectos estructurales: bajo nivel educativo, reducidos cambios de trabajo y bajos ingresos. Construir una vivienda grande en un largo periodo de tiempo y albergar varios hogares con vínculo familiar inmoviliza a los propietarios ocupacional y residencialmente, excepto que logren movilizar la vivienda como activo mediante el alquiler de espacios. Se discute sobre el papel de la propiedad de la vivienda en la confluencia de estas inmovilidades y se reflexiona sobre la reproducción de las desigualdades en el marco de la política habitacional.
Oferta de serviços ecossistêmicos culturais na despoluição de rios urbanos em São Paulo
Authors: Flausino Fábio Richard , Gallardo Amarilis Lucia Casteli Figueiredo
Published: July 2021

Resumo A despoluição de rios representa uma iniciativa de requalificação do ambiente urbano. Córregos revitalizados abrangem ações de saneamento, mas ensejam expectativas de agregar valor à qualidade de vida. A gestão urbana tem o desafio de mensurar o bem-estar proporcionado por políticas públicas. Enquanto os serviços ecossistêmicos culturais representam os benefícios vivenciados no contato com ambientes naturais ou manejados, esse artigo objetiva analisar se esses serviços estão associados a benefícios não tangíveis percebidos pela população em um programa público de despoluição de rios em São Paulo. Os serviços culturais de interações pessoais, lazer, contemplação e espaço para manifestações são os mais percebidos frente àqueles que revelam influência para além do ambiente local e temporal como diversidade cultural e valores religiosos, espirituais e de educação. Recomenda-se que a avaliação de programas dessa natureza possa internalizar a perspectiva desses serviços ecossistêmicos como forma de fortalecer benefícios culturais à população nessa agenda de gestão urbana.

Published: July 2021

Abstract Whereas passenger demand is one of the main risks in passenger transport infrastructure projects on track, this paper aims to propose a demand forecasting model based on artificial neural networks (ANN) in order to contribute to the project management still in its early planning stages. For this, the design of ex post facto type was used in a descriptive research with quantitative approach, where the research group was composed by subway and train stations in the metropolitan region of São Paulo-Brazil. In total, 12 ANN were proposed architectures with 15 different configurations, totaling 180 training processes, testing and validation. For each architecture has been identified the lowest mean square error percentage obtained; and the best architecture, with a hidden layer, was performed relevance analysis by Garson method, the model 4 input variables: the population; the school enrolment; the number of jobs; and per capita income. With the proposed model, one expects to contribute to the theory by adding to demand forecasting models using a robust methodology and, for managers, serve as a tool in studies of economic and financial viability of these projects, still in its planning phase anticipated as an investment decision-making tool.

Abstract The eastern portion of the state of Maranhão is a transitional area between Amazon Rainforest, Cerrado and Caatinga. Knowledge about the flora of this region is very poor, especially regarding Orchidaceae. The aim of this study was to provide a survey of the species of this family in the central area of this region. Fieldwork was performed monthly between December 2015 and April 2019 in the municipalities of Aldeias Altas, Caxias, Codó and São João do Sóter. An identification key, morphological descriptions and illustrations of the species are presented. Orchidaceae is represented in the area by seven genera and 17 species. The richest genera were Catasetum (five species), and Habenaria (four species). Habenaria schenckii is a new record for the state. The majority of the species are epiphytes (eight species, 47%) or terrestrial (seven species, 41%). The municipality of Caxias was the richest, with 13 species (76%), of which six were collected in the conservation units (CU’s) existing in the municipality (Área de Proteção Ambiental Municipal (APAM) Buriti do Meio Municipal and APAM Inhamum). Our data highlight the importance of the CU’s for the conservation of Orchidaceae, and the potential of ecotonal regions for discovering new records for the region.

Transcutaneous neurostimulatory treatment for peripheral polyneuropathy induced by hypereosinophilic syndrome - A case report -
Authors: Kwon Kihyug , Park Ji Eun , Park Woosoo , Lee Teakseon
Published: July 2021

Background: Hypereosinophilic syndrome is a rare disease that increases the number of circulating eosinophils in the body. It has many complications, including peripheral polyneuropathy. Peripheral polyneuropathy often does not respond well to conventional therapies. Transcutaneous neurostimulatory treatment, also known as scrambler therapy, is an alternative modality for the treatment of chronic retractable pain. Case: A 47-year-old woman presented with complaints of bilateral calf pain. She had been under treatment for peripheral polyneuropathy induced by hypereosinophilic syndrome for 7 years. Pharmacologic treatment did not affect the patient’s symptoms. Conclusions: Transcutaneous neurostimulatory treatment was administered to the patient. It was effective on her symptoms, and the effect of pain alleviation continued for 3 months.

Background: Pediatric patients with moyamoya disease are vulnerable to ischemic attacks following physical or emotional stress, such as those experienced during blood sampling. A central venous catheter might be beneficial for blood sampling, and a peripherally inserted central catheter (PICC) is a considerable option for central venous access. However, PICC insertion during anesthetic management is relatively rare.Case: Thirty cases of ultrasound-guided PICC insertion were performed in children undergoing surgery for moyamoya disease after anesthetic induction. Positioning was successful in 22 cases, and 5 were malpositioned. In three cases, the peripheral insertion failed. Adjustment of the insertion depth was performed in nine cases. No complications related to catheterization were observed during the procedure or the catheter indwelling period.Conclusions: We report the successful use of PICC in children undergoing surgery for moyamoya disease with a considerable success rate and low incidence of malpositioning or complications.

This article presents an overview of the projects approved in Porto Alegre between the years 2010 and 2019, through the city’s Special Projects of Urban Impact (PE) development instrument. The concept of “flexible planning” is presented to explain the type of planning practiced today and to describe the PE instrument as outlined in the Porto Alegre Master Plan. In the article, the PE normative framework is presented, followed by a statistical and socio-spatial description of the projects undertaken. The patterns regarding the socioeconomic and urban requirements are presented, as well as the community contributions or benefits that resulted from these projects. The research reveals that, rather than being exceptions, Special Projects have become the norm for large developments in Porto Alegre, resulting in a shock wave of large real estate developments in the city.

Changes in land use have been detrimental to natural ecosystems. In Argentina, the Espinal ecoregion is one of the most affected, with only a few relics remaining. The province of Córdoba is one of the largest agricultural producers, which led to the modification of natural ecosystems, losing the environmental services they provide. This happens in the city of Villa María and especially in its peri-urban territory. The identification and analysis of the fragmentation of the ecosystem structures in this peri-urban area provide a different way of identifying the new ecosystem structures to be considered in the territorial planning of medium or small cities. Six ecosystemic structures (patches) were identified: Residual Ecosystems, Neoecosystems, Neosols, Neohumedales, Surface Runoff Neoredes, and Geophagy. It's processing through a Geographic Information System allowed mapping the survey results and identifying the environmental services that they provide. The fieldwork allowed to show the richness and diversity present; however, their distance and size denote the vulnerability of the patches. The importance of the structures in terms of the provision of services demands the need to consolidate political strategies in municipal management aimed at protecting the patches.
Le genre et ses indices: les normes internationales sur l’égalité femmes / hommes en question

Dans les années 1990-2000, la communauté internationale s’est engagée pour la lutte contre les inégalités entre les femmes et les hommes. Les institutions se sont alors dotées d’outils permettant de mesurer les évolutions dans ce domaine à l’échelle internationale. Divers « indices d’inégalité de genre » ont été élaborés. S’ils ont subi des critiques méthodologiques menant à des réajustements, les cadres conceptuels utilisés n’ont en revanche jamais été analysés à l’aune des savoirs sur le genre. Notre analyse porte sur les indices du FEM, de l’OCDE et du PNUD et révèle que ces indices reposent sur des postulats qui participent d’une vision située et réductrice des rapports sociaux de sexe. Par ailleurs, les domaines dans lesquels sont mesurées les inégalités de genre tendent à réifier les rôles sociaux traditionnels attribués aux femmes et des hommes. Enfin, ces indices, parce qu’ils sont le résultat d’une approche située, mettent en avant certaines formes d’inégalités de genre et en oublient d’autres, ce qui limite largement leur utilisation dans un cadre comparatiste et scientifique.
L’égalité juridique entre hommes et femmes dans le monde arabe après les soulèvements de 2011
Authors: Bernard-Maugiron Nathalie
Published: July 2021

Suite aux soulèvements populaires qui ont traversé le monde arabe en 2011, le principe d’égalité entre hommes et femmes a été renforcé dans plusieurs textes constitutionnels de la région. Mais le statut juridique des femmes demeure souvent inégalitaire par rapport à celui des hommes, notamment en droit pénal, en droit de la nationalité et dans le droit de la famille. De plus, des normes sociales viennent entraver la mise en œuvre des réformes juridiques adoptées pour remédier à certaines inégalités. Or, comme de nombreux organismes internationaux l’ont souligné, la persistance de ces discriminations envers les femmes constitue un frein majeur au développement économique et social de la région.
Infécondité, procréation médicale et inégalités sociales
Authors: Bonnet Doris , Duchesne Véronique
Published: July 2021

Le développement des technologies de la reproduction, et notamment de la fécondation in vitro (FIV), permet aujourd’hui à certains couples (hétérosexuels) infertiles africains d’avoir un enfant. L’offre d’assistance médicale à la procréation (AMP) s’inscrit dans un système de soins libéral qui s’adresse prioritairement aux classes moyennes et urbaines. Certains couples ne trouvent pas dans leur pays les conditions ou les techniques recherchées et sont amenés à se déplacer à leurs frais dans des pays limitrophes ou encore en Europe ou aux États-Unis. D’autres couples résident en France où l’AMP est encadrée par les lois de bioéthique. Ce chapitre montre comment l’espace mondialisé de la reproduction renvoie à un rapport inégalitaire aux biotechnologies de la reproduction des couples africains infertiles selon leurs conditions socio-économiques, mais aussi selon leur lieu de résidence. Ce contexte renvoie au cadre théorique de la « reproduction stratifiée ».
Régimes de temporalités et récits des inégalités au Pérou

Published: July 2021

Dans des entretiens semi-narratifs recueillis en 2005 dans l’ONG La Casa de Panchita à Lima, 32 employées domestiques péruviennes produisent des récits autobiographiques sur l’arrière-fond des inégalités sociales qu’elles perçoivent au sein de la société. Afin de donner du sens à leurs expériences au moment de l’énonciation, certaines déploient plus que d’autres, dans leur récit, des ressources discursives et linguistiques créatives. Dans ce chapitre, nous étudierons l’exploitation particulière des temps verbaux du passé par les locutrices, et la temporalisation dans la narration de leur vécu.

The critical functional part of any high performance resonance based sensor is a mechanical resonator. The performance is measured by resonator quality factor (Q-factor). Damping mechanisms such as thermoelastic damping (TED), anchor loss, surface loss, material internal friction, fluid damping and electronics damping are covered in this review with more focus on gyroscope resonators. Dissipations can be reduced by different means. Hence, the effects of various design to operational parameters on the Q-factor for different configurations, sizes and materials are reviewed in detail. Micro scale ring resonators can achieve a Q-factor of the order of hundreds of thousands. Macro scale hemispherical resonators are suitable for ultrahigh Q-factors. High temperature sensor operation is not preferred because of TED, while sub-zero operation is limited by material internal friction. Few orders of dissipation increase are seen with thin film metallic coating due to TED and coating material internal friction. High precision fabrication is mandatory to achieve the designed minimum anchor loss as it is highly sensitive to fabrication imperfections. Q-factor sensitivity to operating pressure is different for different resonator configurations. This review study helps to build a comprehensive mechanical resonator design, realization and operation strategy to achieve high sensor performance. A roadmap on future research requirements for developing compact mass producible CVG type sensors with ultrahigh Q-factor is also highlighted.

This paper proposes the use of the Gbest-Guided Artificial Bee Colony (GABC) algorithm to solve an online optimization problem for the leaderless distributed formation control of hexarotor Unmanned Aerial Vehicles (UAVs). The GABC is employed to optimize a cost function for each agent while ensuring the convergence of the fleet to the target position and averting both obstacles and collisions with other UAVs. The GABC algorithm has been shown to be competitive with some other conventional biological-inspired algorithms such as the Particle Swarm Optimization (PSO). Fault-Tolerant Control (FTC) methods are presented and tested on several scenarios, particularly we considered the cases of loss of agents and actuator faults in the fleet. Results show the success of the proposed FTC methods to minimize the faults effect on the formation final goal.

Cellulose nanocrystals (CNCs) have gained worldwide interest for their properties. CNCs are mostly produced by acid hydrolysis of cellulose-rich biomass, but its’ quantification is still complicated and tedious. Here, we describe a rapid method for the determination of CNCs concentration using Calcofluor White (CW) fluorescence dye. This method is robust, easy, selective for crystalline cellulose and suitable for routine measurement in CNCs production.
