Authors: Ivanov I.K. , Pugachenko S.E. , Tkachev N.A.
Published: May 2020

The paper deals with manned orbital station-hotels built for regular visits of space tourists. The purpose of the study was to find a rational method to dispose waste products from the orbital station operation. For three options of the crew number, we introduce four ways to dispose waste products from tourists --- residents of the near-еarth and near-lunar orbital station-hotels. During the study, we used a system analysis method and developed a mathematical model of the manned space infrastructure. We estimated the effect of each method on economic costs in the design, manufacture and operation of the orbital stations and carried out a comparative analysis of the possible methods of waste disposal. Based on the results obtained, we propose rational options for both orbital stations. As a criterion of rationality, we chose indicators of program costs and unit costs for one visit by one tourist.
Analysis of the Orbital Approach Dynamics of the Space Debris Collector to the Fragment of Debris by the Method of Thrust Reversal with Interruption
Authors: Arinchev S.V.
Published: May 2020

The debris collector and a debris fragment move along random noncoplanar orbits in the altitude range of 400--2000 km. The thrust of the promising engine is 5000--25 000 N, the specific impulse of the promising fuel is not lower than 20 000 m/s. The remaining fuel after approach is not less than the specified. The debris collector undocks from the base station, transfers from its orbital plane to the debris fragment orbital plane, performs phasing, approaches the fragment, grabs it and returns to the base station. The paper considers only the stage of orbital approach. The duration of the entire flight mission is limited to one day. The phasing time is insufficient, therefore, at the start time of the orbital approach, the distance to the target is ~ 100 km, the relative velocity is ~ 1 km/s. On the other hand, for reliable and safe grabbing of a debris fragment, it is necessary to provide a distance of ~ 1 m and a relative velocity of ~ 1 m/s. It is shown that this can be achieved by approach using the method of thrust reversal with interruption. An effective algorithm of approach with target is proposed. An analysis of the orbital approach dynamics was performed by joint numerical integration of the orbital motion equations of the debris collector and the debris fragment by the 4th-order Runge --- Kutta method. Approach is performed in 6 cycles. In each cycle, the engine turns on three times. Two cycles are performed by sustainer engines, four cycles are performed by auxiliary engines of lower thrust. The fuel depletion and the non-sphericity of the Earth's gravitational field according to the 2nd zonal harmonic are taken into account. Calculation example is considered. Convergence estimates of the integration procedure by the resultant distance to the target and the resultant relative velocity are given. Resultant orbital approach is oscillation process with heavy damping. Damping is ensured by multiple firings of the sustainer (auxiliary) engine
A produção do espaço urbano na cidade de Campinas 2000-2017
Authors: Barbutti Marcio Rodrigo , Munia Benfatti Denio
Published: May 2020

O artigo proposto decorre de uma dissertação de mestrado e analisa a expansão urbana recente do município de Campinas a partir do levantamento dos loteamentos aprovados no período 2000–2017. Esta base de dados nos permite compreender as diferentes configurações da expansão e transformação urbana da cidade nestes últimos vinte anos. Como nem todos os empreendimentos aprovados foram efetivamente realizados, a pesquisa contrapõe as informações cadastrais com as transformações verificadas nas imagens da plataforma Google no período considerado. A acessibilidade, neste trabalho, é tomada como um elemento que influi fortemente nos valores imobiliários. Em contrapartida, seus diferentes noveis de serviço estariam criando áreas visivelmente segregadas no processo recente de expansão urbana. Por um lado o sistema viário principal, as rodovias e as principais avenidas de circulação automobilística e, por outro, as áreas mais cativas do transporte público estão sendo determinantes na localização diferenciada dos novos loteamentos. No caso específico, além da influência dessas infraestruturas, a legislação urbanística local tem contribuído para induzir transformações significativas na forma urbana e na construção da cidade, principalmente de suas bordas mais recentes.
A efetividade do instrumento ZEIS vazias na inserção da Habitação de Interesse Social na cidade planejada
Authors: ROCHA Marecilda Sampaio da , MELLO Cristina Maria Correia de , REIS Talitha Mendes
Published: May 2020

Este artigo aborda como o instrumento urbanístico denominado ZEIS de vazios vem sendo pensado e implementado na cidade planejada, no caso Brasília - DF. Discute-se sua efetividade em atender a demanda de habitação de interesse social, debatendo sobre os limites e as potencialidades desse instrumento, que surgiu pela necessidade de flexibilização de parâmetros urbanísticos para viabilizar a moradia social. Mas será que isso vem atendendo ao ideal planejado? A utilização de outros instrumentos poderia potencializar os resultados de ZEIS de vazios quando se pensa na inserção de moradias sociais em áreas que garantam o efetivo direito à cidade, com dignidade às famílias, integrando-as ao meio social adjacente a esses núcleos? A metodologia utilizada partiu da revisão bibliográfica sobre o tema, seguido do levantamento de dados históricos e ocupacionais e das ações do poder público para a criação de ZEIS de vazios. Averiguou-se nos estudos se as ações adotadas foram relevantes para suprir a demanda socioespacial e do direito à cidade da população de baixa renda no Distrito Federal. O que se constatou foi a pouca efetividade desse instrumento que, apesar de contemplar a delimitação de algumas áreas no planejamento local, ainda se encontra aquém da demanda de moradia.

ABSTRACTDengue Hemorrhagic Fever (DHF) is influenced by the environmental factors; climate and population mobility. The DHF incident mapping is conducted to know its distribution and the areas belong to high-risk of DHF. This study aims to know the DHF incident mapping, climate conditions, and population mobility at Putat Jaya in 2015-2017.This study is an observation analysis by using the ecology time series study. There were 110 samples population. This study used a correlation test to know the strength and weakness of climate variable, population mobility number towards the DHF incident. The data used a primary and secondary data. Most cases of DHF incident are found in community areas (RW) where the distance between citizen’s house is narrow. The mapping showed the distribution pattern of DHF in each RW was grouping and spreading. Based on the correlation test, if the rainfall is higher, the DHF incident increases (r = 0,278). If the air temperature is higher, the DHF incident decreases (r = -0.480). If the humidity is higher, the DHF incident increases (r = 0.282). If the duration of solar radiation is higher, the DHF incident decreases (r = -0,150). If the population mobility rate is higher, the DHF incident increases (r = 0,413). There was an environmental factor that support the DHF incident at Putat Jaya. It causes a high-risk exposure to DHF, thus the case was grouping and spreading. In addition, it still need a cooperation between the Health Center and the society to control the DHF incident. Keywords: Mobility Rate, Climate, Larva Density, Mapping

Published: May 2020

Background: Environmental problems in Indonesia are complex to solve. Most people in Indonesia still inappropriately dispose feces in wrong places. Based on the Joint Monitoring Program WHO/UNICEF, 55 million people in Indonesia still had unhygienic defecation behavior. Rangkah Village, Tambaksari District face the same problem because its population is not balance with its area, so settling septic-tank becomes a problem. Objective: This study identified community’s feces disposal behavior in Community Association Number 8 of Rangkah Village. Method: The primary data were collected through questionnaires, interview, and observation distributed to 249 respondents in Community Association Number 8 of Rangkah Village. While the secondary data were obtained through primary healthcare report. The analysis was done by using Slovin formula. Results: The respondents had good knowledge and attitude towards the importance of having latrines, septic-tank, and the danger of disposing feces into a river. However, environment has a big impact on the respondents to dispose fece into the river. They have already had latrines, but not septic-tank due to the lack of landfill for septic-tank and community’s low economic level.  Conclusion: Feces drain from the toilet to the river through pipes, and this causes environmental pollution which spreads diseases to people around the river. This problem still cannot be solved by the healthcare providers and local government although they have done a program that deals with this problem.

Published: May 2020

Managerial intellectual capital is one of the attributes of a global mindset, associated with knowledge, skill level, and creation of an organization competitive advantage. This paper sought to delve into the concept of internationalization of commercial banks by examining the relationship between managerial intellectual capital and internationalization of commercial banks in Kenya. The paper used positivism philosophical approach and adopted cross-sectional descriptive research design. The target population was top and middle level managers in commercial banks in Kenya. Data was collected using a structured questionnaire and analyzed using Statistical Package for Social Sciences (SPSS) version 22.0 to obtain both descriptive and inferential statistics.  In addition, Structural Equation Modelling (SEM) was used to establish the influence of managerial global mindset attributes on internationalization of commercial banks in Kenya. The study established that there was a significant and positive relationship between human capital, relational capital and structural capital as attributes of managerial intellectual capital and internationalization of commercial banks in Kenya. Further, the study established that human capital, relational capital, and structural capital have significant influence on the success of internationalization strategy of commercial banks in Kenya. Thus, structural capital, human capital and relational capital, which are the managerial intellectual capital attributes, jointly influence the success of the internationalization of commercial banks in Kenya. It is therefore recommended that when appointing managers, the management of commercial banks should consider factors such as an individual’s knowledge of global industry, global value networks, and global organization.
Application of a Bandpass Filter for the Active Vibration Control of High-Speed Rotors
Authors: Pawlenka Miroslav , Mahdal Miroslav , Tuma Jiri , Burecek Adam
Published: May 2020

This study concerns the active vibration control of journal bearings, which are also known as sliding bearings. The control system contains a non-rotating loose bushing, the position of which is controlled by piezoelectric actuators. For governing the respective orthogonal direction of the journal motion, the control algorithm realizes a proportional controller in parallel with a bandpass filter of the IIR type. The bandpass filter is of the second order and its centre frequency is self-tuned to be the same as the whirl frequency that results from the instability of the bearing journal due to the oil film. The objective of active vibration control is to achieve the highest operational speed of the journal bearing at which the motion of the rotor is stable. The control algorithm for the active vibration control is implemented in Simulink and realized in a dSPACE control system.
The Exact Frequency Equations for the Rayleigh and Shear Beams with Boundary Damping
Authors: Coleman Matthew P. , McSweeney Laura A.
Published: May 2020

While the Euler-Bernoulli beam is the most commonly utilized model in studying vibrating beams, one often requires a model that captures the additional effects of rotary inertia or deformation due to shear. The Rayleigh beam improves upon the Euler-Bernoulli by including the former effect, while the shear beam is an improvement that includes the latter. While all of these problems have been well studied when subject to energy-conserving boundary conditions, none have been solved for the case of boundary damping. We compute the exact frequency equations for the Rayleigh and shear beams, subject to boundary damping and, in the process, we find interesting connections between the two models, despite their being very different.

The sound radiation characteristics of a structure depend on its critical frequency. The expression for theoretically estimating the critical frequency of a composite cylindrical shell has not yet been reported. Thus, the practice is to use the expression for the composite panel for determining the critical frequency of a composite shell. In this work, critical frequencies of composite shells are investigated. As the critical frequency depends on the speed of the bending wave, an expression for the speed of the bending wave is first derived. It is seen that the curvature causes an increase in the speed of the bending wave and the orthotropic nature of the cylinder reduces the speed. An expression for the critical frequency of a composite cylindrical shell is then derived. The curvature causes a reduction in the critical frequency and the influence is significant in acoustically thick cylinders. Hence, the critical frequencies of such cylinders cannot be determined by using the expression for the panels. Effects of transverse shear deformation on the speed of the bending wave as well as the critical frequency are then investigated. Transverse shear deformation causes both reduction in the speed of the bending wave and an increase in the critical frequency. The orthotropic nature of the cylindrical shell increases the critical frequency further. The critical frequency of a typical composite cylinder is determined through a numerical simulation and the results are in agreement with the results obtained using the expressions derived. The critical frequency of a typical composite cylinder obtained through an experiment is presented. With this work, expressions for theoretically estimating the speeds of the bending waves and critical frequencies are derived for a composite cylindrical shell considering transverse shear deformation.

Honeycomb sandwich composite cylindrical shells are widely used in aerospace structures. Experimentally observed modal densities of such shells are not reported. In this work, modal densities of a typical honeycomb sandwich composite cylinder are obtained experimentally by measuring the drive point admittance. The results are in good agreement with those estimated theoretically that incorporated transverse shear deformation. Its limitations at higher frequencies are investigated and the frequency beyond which the estimation is in error is determined. The results provide an example to prove the need for measuring the imaginary part of the driving point admittance and using it in the determination of the modal densities of honeycomb sandwich-type structures. Experiments are carried out with two boundary conditions for the cylinder and the results provide experimental evidence for the fact that the modal densities at high frequencies do not depend on the boundary conditions. At higher frequencies, it is expected that both of the face sheets vibrate independently. This frequency can be approximately estimated as the fundamental bending mode frequency of the wall of the honeycomb core. The modal density determined through the measured driving point admittance will have a sharp reduction at this frequency and this feature can be used in identifying this phenomenon. The experimental results are in very good agreement with the above results.

Les relations entre les conditions de production du lait et les teneurs en composés d’intérêt nutritionnel de fromages fermiers au lait de vache ou de chèvre ont été étudiées en conditions réelles de production au sein de 4 filières fromagères (Abondance, Tomme de Savoie, Salers/Cantal et Rocamadour). Au total, 432 fromages, dont 306 au lait de vache et 126 au lait de chèvre, produits tout au long de l’année par 74 producteurs fermiers ont été analysés. Dans un premier temps, les effets respectifs des conditions de production du lait et de la transformation fromagère sur la variabilité de composition du fromage ont été quantifiés. Dans un second temps, les relations entre la composition du fromage et les conditions de production du lait, préalablement identifiées au moyen d’enquêtes, ont été étudiées. Le fromage fermier se caractérise par une grande variabilité de composition qui dépend majoritairement de la transformation fromagère pour la vitamine B9 et les minéraux et des conditions de production du lait pour les acides gras (AG), les vitamines A et E et les caroténoïdes. L’espèce animale explique une grande partie de la variabilité en certains AG et en β-carotène dans le fromage. Les teneurs en micronutriments liposolubles et le potentiel antioxydant du fromage dépendent principalement de la nature de la ration fourragère (pâturage vs fourrages conservés) quelle que soit l’espèce animale. Les rations à base de pâturage sont associées à des teneurs en caroténoïdes et en vitamines A et E et à un potentiel antioxydant dans le fromage plus importants. En revanche, les facteurs de variation du profil en AG du fromage ont différé dans cette étude entre les vaches et les chèvres. Pour les fromages au lait de vache, il dépend principalement de la nature de la ration fourragère (pâturage vs fourrages conservés). Les fromages associés au pâturage sont plus riches en AG saturés et insaturés à longue chaîne (≥ C18) et plus pauvres en AG saturés à courte et moyenne chaîne (C6:0 à C16:0). Le profil en AG du fromage au lait de chèvre dépend principalement de la proportion de matières grasses apportées par les concentrés dans la ration, du stade de lactation des animaux et dans une moindre mesure de la présence ou non de lin dans les concentrés. Ce fromage est plus riche en AG à longue chaîne et plus pauvre en AG saturés à courte et moyenne chaîne lorsque la proportion de matières grasses apportées par les concentrés est plus importante, les concentrés contiennent du lin et les animaux sont en début de lactation. En conclusion, ce travail a permis de collecter des données représentatives et détaillées sur les caractéristiques nutritionnelles de différentes variétés fromagères et de hiérarchiser les effets des principaux facteurs de production responsables de la variabilité de composition du fromage.
Superovulation chez la jument avec les hormones gonadotropes : le point sur la situation et nouvelles données

Chez les espèces domestiques de rente, les traitements de superovulation sont destinés à augmenter le taux naturel d’ovulations, afin de produire plusieurs embryons au cours d’un même cycle et de les transférer chez des femelles receveuses. Pour l’espèce équine, aucun traitement n’est commercialisé car, d’une part, les gonadotrophines commercialisées pour les autres espèces de rente sont inefficaces chez la jument, d’autre part, les réponses aux traitements montrent une grande variabilité.
Chez la jument, les traitements administrés utilisent la FSH équine (eFSH). La variabilité des réponses concerne à la fois les capacités de stimulation, représentées par le nombre de follicules préovulatoires, le nombre d’ovulations et le nombre d’embryons transférables. Comme pour l’ensemble des espèces de rente, les causes de cette variabilité sont multiples. Parmi celles-ci une posologie d’administration des gonadotrophines inadaptée est responsable d’anomalies de la folliculogénèse et de perturbations endocriniennes qui conduisent à une diminution de la production d’embryons. Partant des modèles proposés dans l’espèce bovine, de nouvelles études ont été conduites chez la jument afin de déterminer les interactions entre les altérations folliculaires et endocrines et de préciser quels étaient les paramètres agissant sur la production d’embryons. Une posologie idéale a ensuite été recherchée comme étant capable de reproduire des taux plasmatiques physiologiques de FSH, susceptibles d’induire une superovulation, sans effets indésirables. Cette posologie correspond à l’apport d’une quantité quotidienne de eFSH égale à environ 50 % du taux de production journalier de la jument ovariectomisée. A partir de l’ensemble de ces données, un protocole de traitement peut actuellement être proposé, avec l’espérance d’obtenir pour une jument et par cycle traité une moyenne de 3 à 4 ovulations et 1,8 à 2,5 embryons. Différentes stratégies sont ensuite abordées qui pourraient améliorer l’efficacité des traitements.
Cependant la commercialisation future d’une préparation de eFSH pour l’espèce équine est incertaine, du fait de la fourniture limitée des hypophyses nécessaires, des contraintes sanitaires liées à ce type de produit et de la nécessité de préparer un produit spécifique pour cette espèce.
