Authors: Thi Ha Bui , Gia Duong Bach 
Published: June 2019

Abstract: In the paper, the new microwave modules of NanoDragon satellite’s receiver were designed and fabricated. Purpose of this design is not only reduce budget but also respond to frequency requirement, bandwidth and transmission rate. The microwave modules consist of low noise amplifier (LNA), mixer and local oscillator (LO). These modules operate at S band according to requirement of satellite. Firstly, each module was designed, simulated, fabricated and measured. Then they were integrated together. Output of integrated microwave modules is IF signal with bandwidth is suitable for demodulation PCM – PM (BPSK). And have high gain value conform to receiver’s requirement. Simulation result of low noise amplifier is 19.108 dB at 2.9 GHZ. Simulation result of integrating two stage LNA become 2-stage LNA have gain value over 38 dB. Gain value obtained is 11.5 dB when measurement. Integrating microwave modules result is 10.5 dB with gain value. That mean this microwave modules of receiver operated very well. LNA was very good. This subsystem can apply for NanoDragon satellite’s receiver and receiver of ground station.
Keywords: Receiver, Microwave Modules of Receiver, Satellite, NanoDragon satellite, LNA, Mixer, LO, IF.

O Design de Informação e a narrativa diagramática em Whale Hunt de Jonathan Harris
Authors: Franco Juliana Rocha 
Published: June 2019

Uma questão que atravessou os anos 80 e 90 do século passado, a “hipertrofia das imagens” no mundo contemporâneo, poderia ser nos dias de hoje reformulada e ampliada. Vive-se atualmente uma imersão na hipertrofia dos dados na qual as modalidades de criação, organização e acesso à informação têm se alterado drasticamente. Dentro desse contexto, o uso de bancos de dados e ferramentas interativas que promovem o Design de informação tem se revelado importantes para práticas de produção de sentido e organização no mundo contemporâneo. O presente trabalho busca compreender a potencialidade narrativa dos ambientes midiáticos de visualização dinâmicos de bancos de dados digitais. Especificamente é empreendido um estudo de caso da obra Whale Hunt, do artista multimídia Jonathan Harris. O que buscaremos mostrar no presente trabalho, é que uma interface pode ser um poderoso dispositivo narrativo ao ser trabalhada diagramaticamente. Em Whale Hunt o usuário não só́ interpreta a narrativa, mas como também a explora e a configura. A premissa básica é a da agência como interação.

A survey of important decisions and settings needed for attaining a sustainable world
Authors: Larsson Nils O. 
Published: June 2019

The main objective of the methodology to be presented is to find the most important decisions within the area of discussion. Focussing on the important decisions and in which environment they are taken gives an increased possibility of solving the problems in question. The analysis should cover decisions on all levels i.e. individual, informal and formal groupings of people, nations, group of nations as well as decisions on the global level. In this paper I will present some examples that could serve as an elucidation of the method. The goal of the method is to outline a system for a sustainable control of global renewable as well as non-renewable resources such as cultivable soil, water, fish, clean air, minerals, and oil. In order to handle the complexity of the problem the analysis must be limited to the most important factors in a long as well as short time view. A number of factors to be used in describing the methodology is presented. In order to simplify the finding of the decisions influencing an analysis of sub-factors is necessary. Decisions having an important influence on the above factors are presented and the information needed for making relevant decisions. The next step in the analysis is to create a decision hierarchy and what organizations should be responsible for taking these decisions.
The current issue of JoS

Deeply shocked we had to take note that Nils O. Larsson, one of the authors of the last issue of Journal of Sociocybernetics, passed away very unexpectedly. Since many years Nils O. Larsson was a member of the Research Committee on Sociocybernetics (RC 51) and the International Sociological Association (ISA). He took part in the World Congress of Sociology 2010 in Gothenburg, where he organized the RC 51 – Session “Global problems require solutions with a global perspective”. This session was strongly related to one of the main themes of the XVII World Congress of Sociology: sustainability, a subject which had become more and more in focus due to the threatening climate change and the present economic crisis. In the face of the increasing and sometimes overwhelming complexity of this problems it was Nils' ambition to develop an adequate research method that can analyse and design human activity systems on individual, family, as well as society and global level. He called this methodology "Decision Settings Analysis". Three of the papers, presented in his world congress session were published later in Volume 10 of JoS. But it was not granted to Nils that he could lived to see this result of his efforts. He died during the editorial process what came to know to us when the Volume already was published. Today, while we are preparing the VXIII World Congress of Sociology in Yokohama, we miss Nils O. Larsson very much.The current issue of the Journal of Sociocybernetics includes three theoretical oriented articles and one empircal study. In their article
Changing Social Focussing in the Development of Jazz Music
Authors: Hay James , Flynn J David 
Published: June 2019

This paper traces the development of jazz musical styles by relating those styles to the organization of jazz musicians and the social context of American society. The authors use a theory developed by Flynn and Hay (2012) derived from chaos and complexity science. The Flynn/Hay theory states that social focussing (chaos, complexity or order: SF) is directly proportional to internal structure (differentiation: D) and inversely related to external information (centrality: C). In mathematical terms: SF = D/C.The authors of this paper describe the social focussing of jazz styles in terms of being chaotic, complex or ordered. They then relate the styles of social focussing to the differentiation of the social system of jazz musicians, and the centrality inputs from the surrounding American society. Their results demonstrating that the style of jazz at each period from the late 19th century to the present era, is dependent upon the ratio of d/c.They conclude that the same analysis could be applied to subsystems of the jazz system, including the development of jazz styles in different geographic regions, as well as within each band and even over the career of each musician, in a kind of fractal effect, where the shape of social focussing is the same at each level.
How do collectives of amateurs handle complexity on financial markets while deciding?
Authors: Welbers Lydia Judith 
Published: June 2019

This paper questions how investment clubs – as small groups of retail investors that pool their money – cope with issues of hyper-complexity and truth while deciding together where to invest their money. This may be challenging because investment-decisions are characterised by informational complexity, an unknown future and double contingency.
By employing ethnographic data, this paper traces how investment clubs reach a collective decision despite hyper-complexity. It will be shown how the members of the group struggle to make sense of and to find a shared definition of a situation. During this process they try to reduce complexity by evaluating and deciding collectively. The ways the different groups achieve this is influenced by the group composition, their organisational structure and the interaction order. In some groups negotiations are an essential part of their meetings whereby complexity is initially cultivated. Negotiations are used to develop a shared definition of the situation. These groups question if the truth can be uncovered in financial markets. Other groups reduce complexity by using certain techniques to uncover the true value of a stock. These ways of coping with complexity are bound to certain ways of organising and types of members. Accordingly, successful evaluating and deciding, which means that decisions are made, is bound to several exclusions that are made legitimate by the inclusion in the financial market. In summary, the paper adds new insights to processes of decision making in situations that are characterised by complexity.

The implementation of social welfare development programs in developing countries is generally focused on the empowerment program of the poor, which is more nuanced in a participatory approach involving the community, business and government. empowerment is considered appropriate to be one of the policy choices in the development of social welfare today. The development of social welfare based on the principle of empowerment is intended that in the handling of the poor, it must be done through increasing the capacity of human resources to increase independence (Law Number 13 of 2011).
Regional development has an impact on national development. Poverty reduction policies realized through community empowerment programs have become the main agenda and prior development in Baleendah Subdistrict, especially Rancamanyar Village. One of the poverty alleviation programs through community empowerment carried out in Rancamanyar Village is the Housing Assistance Program for uninhabitable houses. Various local government efforts to reduce the number of uninhabitable houses are still considered uneven. With the limited management and processing of survey data in the regions, it is one of the factors that do not help the existing policies.
With the construction of a geographic information system for uninhabitable homes, one of the efforts that must be taken by the local government in order to support and assist in making decisions for uninhabitable houses is to conduct geographical analysis and mapping of uninhabitable houses in Rancamanyar Village, so that help is not the wrong target.

Published: June 2019

Ferrocement is composed of cement mortar reinforced with small diameter closely spaced steel wire mesh to form a thin section conforming high performance of serviceability. The present study investigates the performance of ferrocement panels focused on the mechanical properties, water absorption and durability. A series of specimens were cast with single and double mesh layers. Flexural performance was carried out following sixty days in temperature cycle and in corrosion cell. These results was compared with the controlled sample. The test results shows that the flexural strength performance was reduced by 52% and 35% for single and double layer wire mesh samples respectively followed by corrosion environment. First crack load also changed after completion of sixty temperature cycles. This load is 27.3%, 42.3% and 31.8% of failure load for controlled sample, sample in room air after every temperature cycle and samples in room air following quenching after every temperature cycle respectively for single mesh layer sample, and for double mesh layer sample these values are 38.9%, 30.1% and 17.7%. Early first crack is found for the samples following quenching and cooled in room air; however, both types of samples are in low absorption level. This data represents that double layer mesh specimen exhibits better when compared to single layer mesh specimen in strength and corrosion parameters.

Published: June 2019

Abstract. In this study, four different nanostructures precursors, pistachio wood, walnuts wood, forest wood and coal (Anthracite) were selected to produce activated carbon. The experiments were done in industrial scale using a rotary furnace with temperature between 850 and 920 ºC for 45 minutes followed by steam. The product was grounded and divided in three particle sizes, 8x30, 30x50, and 60x80 meshes. The physical properties and surface chemistry of the activated carbon samples were determined by imaging of BET-N2 adsorption. The results obtained from measurements of iodine and methylene blue numbers, surface area, pore volume and comparison of surface area and pore volume, show that by decreasing of particle sizes of each sample, increase the surface area and micro pore volumes significantly. The magnitude of changes in surface area with particle size is a significant factor in defining the effectiveness and suitability of an activated carbon for the production of carbon molecular sieve. Our results indicate that the highest pore volume belongs to pistachio wood, which was increased from 0.168 to 0.271 cm3/g from 8x30 to 60x80 mesh.
Resumen. En este estudio, se seleccionaron cuatro precursores de nanoestructuras diferentes, madera de pistache, madera de nueces, madera de bosque y carbón (antracita) para producir carbón activado. Los experimentos se realizaron a escala industrial utilizando un horno rotatorio con una temperatura entre 850 y 920 ºC durante 45 minutos, seguido de vapor. El producto se molió y se dividió en tres tamaños de partículas, en mallas de 8x30, 30x50 y 60x80. Las propiedades físicas y la química de la superficie de las muestras de carbón activado se determinaron mediante imágenes de la adsorción de BET-N2. Los resultados obtenidos de las mediciones de los números de yodo y azul de metileno, área de superficie, volumen de poros y comparación de área de superficie y volumen de poros muestran que, al disminuir los tamaños de partícula de cada muestra, aumenta significativamente el área de superficie y los volúmenes de microporos. La magnitud de los cambios en el área de la superficie con el tamaño de partícula es un factor significativo en la definición de la efectividad y la idoneidad de un carbón activado para la producción de tamiz molecular de carbono. Nuestros resultados indican que el mayor volumen de poros pertenece a la madera de pistache, que aumentó de la malla de 0.168 a 0.271 cm3/g de 8x30 a 60x80.
Morphofunctional characteristics of leaves and fruits in Maloideae (Rosaceae): a. Microstructure of surface tissues
Authors: Kumachova T. Kh. , Voronkov A. S. , Babosha A. V. , Ryabchenko A. S. 
Published: June 2019

Background. The formation of cover tissues (epidermis, cork), providing a connection with the environment, in the evolution of flowering plants was one of the main consequences of the transition to life on earth. The epidermis, which emerged as a device for protecting deeper underlying tissues from drying, subsequently acquired additional functions (participation in gas exchange and transpiration, absorption and isolation of certain substances as well as protection from the penetration of pathogens) and became a multifunctional tissue consisting of several types of cells (basic, stomatal, and trichomes). Features of the fine structure of the epidermis are of interest in representatives of the subfamily Maloideae Werber (Rosaceae Juss.), which grow, inter alia in mountain agrobiocenoses with their rather harsh conditions. They extended their area of distribution to various habitats due to the development of structural adaptations that play an important role in the formation of resistance to stressors of different etiologies.Objective. Representatives of 4 genera were chosen as model objects from subfam. Maloideae for the study: Malus domestica Borkh., Pyrus communis L., Cydonia oblonga Mill., and Mespilus germanica L.Materials and methods. Mature leaves and fruits were selected from the middle part of the crown of three model trees of each species. The samples were studied by scanning electron microscopy (SEM), with a freezing attachment.Results. Leaves of Maloideae were found to be hypostomatic, while the abaxial (lower) epidermis is multifunctional: it performs a barrier function together with the cuticle. Formation of the cuticular nature can be attributed to the surface structures: peristomatic rings and ridges as well as radially extending folds, all forming a specific microrelief. The adaxial (upper) and abaxial surfaces clearly differ not only in the features of the structure, but also in the specificity of the microrelief’s arrangement. Species-specific traits were also found in the structure of the surface tissue of the pericarp. M. germanica, unlike the other species, does not have a continuous cuticular cover and wax deposits: most of a mature fruit’s surface is covered with a peeling cork layer. In the study of the surface of C. oblonga fruits, numerous rather large stomata with peristomatic rings and cuticular cushions were found similar to those in leaves.Conclusion. Surface structures of leaves and fruits in subfam. Maloideae include formations of cuticular nature, with different specificities of microrelief shaping due to the functional load of the epidermal tissue and environmental conditions. They can also be involved in building resistance to biotic stressors. The obtained data on the features of the fine structure of surface tissues are of interest for applied and theoretical studies, especially environmental and botanical, relating to taxonomic issues.
Viability of pollen in sweet cherry (<i>Cerasus avium</i>) varieties of different ecogeographic origin in the Northwestern region of Russia
Authors: Orlova S. Yu. , Pavlov A. V. , Verzhuk V. G. 
Published: June 2019

Background.Sweet cherry is an unconventional fruit crop for the Northwestern region of Russia. Identification of cultivars adapted to the conditions of the northwest requires a comprehensive study of cultivars of different ecogeographic origin and, specifically, morpho-physiological characteristics of pollen, which ensure the productivity of sweet cherries.Materials and methods.The field sweet cherry collection maintained at Pushkin and Pavlovsk Laboratories of VIR served as the material for the study carried out in 2017 at the Plant Diversity Long-Term Storage Laboratory. Twenty-four sweet cherry accessions belonging to five different groups were studied: I – Northwestern (bred at VIR); II – Central; III – Central Black Soil (all three are regions in Russia); IV – Belarus; and V – Estonia. Viability of pollen was assessed by germinating on an artificial medium with 10% sucrose and 0.6% agar. Pollen viability results were statistically processed using StatSoft Statistica 13.0 and Microsoft Excel.Results.The initial viability of pollen for almost all varieties in 2017 was low. High percentage of pollen germination was characteristic of cvs. ‘Krasnaya sladkaya’ (gr. I, 50.0%), ‘Leningradskaya rozovaya’ (gr. I, 61.8%), ‘Adelina’ (gr. III, 53.5%) and ‘Zarya Vostoka’ (gr. III, 60.3%). After storage in liquid nitrogen, the level of pollen germination increased in all cultivars of groups I and V as well as in a number of cultivars from group II (‘Raditza’, ‘Iput’, ‘Rechitsa’ and ‘Fatezh’), group III (‘Zarya Vostoka’, ‘Rondo’ and ‘Orlovskaya rozovaya’) and group IV (‘Severnaya’ and ‘Vityaz’). Pollen viability after cryopreservation significantly decreased by 8.7‑17.3% in cvs. ‘Bryanochka’ (gr. II), ‘Alebastrovaya’ (IV),’ Bryanskaya rozovaya’ (II) and ‘Adelina’ (III). Pollen viability parameters (length of pollen tubes and percentage of germinated pollen grains) positively correlated prior to immersion into liquid nitrogen from r = 0,54 (gr. III) to r = 0,76 (gr. II), while after cryopreservation, they showed weak correlation (r = 0,28) in gr. I, and strong one (r = 0,79) in group IV. In the length of pollen tubes and the level of viability, the parent cv. ‘Leningradskaya chernaya’ had practically no connection with cv. ‘Raditsa’ (r = 0.09), while with cv. ‘Meelika’ the correlation was medium negative (r = –0.49); correlations between the parent cv. ‘Krasnaya plotnaya’ and cvs. ‘Sopernitsa’, ‘Bryanochka’ and ‘Vityaz’ were medium (r = 0.57) and high (r = 0.78 and r = 0.83), respectively.Conclusion.In their level of pollen viability, the introduced sweet cherry cultivars are similar to or even exceed the cultivars native to the northwest (bred at VIR).
