The sands of various dispersion&origin can watch as basic filler for tonnage build & industrial compounds. The work is devoted to the urgent topic of obtaining cheapened epoxy materials with a high content of natural and building sand. In the case of composite optimization, it is possible to obtain valuable competitive multitonnage composites, moreover, while maintaining the original performance properties or even improving them. In our work, the sand from Ukrainian mines & rivers were used. It is tree types of sand: A) “Quarry” – from industrial carrier in nord of Ukraina; B) “Bottom” – from bottom of big river (Desna); C) “Fabric” – industrial sand TM Stark, Ukraina. A number of practically important properties of composite materials based on epoxy resin and sand of various types and dispersions (50 wt%) have been established. It is shown that 50 wt% of all used sands leads to essential increasing of AbrasiveResistance and SwellingResistance, and microhardness. At same time, 50%-filling decreases investigated strength parameters (to compression & to bending). Is important that sands let reach a high esthetic characteristics of composites: in this simple method can obtain wood-, stone-, honey-like composite materials for building, design & décor. The prospects for the implementation of these results are quite wide, since they cover both large-tonnage construction and repair, innovative industries, as well as small repair segments that are now developed (car service, museum restoration) and handmade. At the same time, this work only opens up these prospects and can become the basis for further scientific and practical research

The pore-forming activity of SsoHel308 helicase from extreme thermophilic archaea Saccharolobus solfataricus has been demonstrated for the first time. This protein, embedded into rabbit erythrocyte membranes, may cause erythrocyte hemolysis. It has been shown that this enzyme forms pores in a flat artificial bilayer membrane and acts as the transformer. After embedding this enzyme into bilayer lipid membranes, the membrane conductivity alters. Taken together, our results show that SsoHel308 helicase is able to form pores in artificial bilayer membranes and, in some cases, the current that flows across the membranes shares features typical of ion channels. The short lifetime of the pores in the membrane significantly reduces the toxicity of helicase for a living cell, and the possibility of directed translocation of single-stranded DNA in the presence of ATP will enable the use of this enzyme as a molecular syringe for injecting single-stranded DNA into living cells.

The aqueous environment and ionic surrounding are the most important factors determining the conformation of DNA and its functioning in the cell. The specificity of the interaction between DNA and cations is especially pronounced with a decrease in water activity. In this work, we studied the B-A transition in high molecular weight DNA with a decrease of humidity in the film with different contents of Na+ ions using FTIR spectroscopy. The IR spectrum of DNA is not only very sensitive to the state of its secondary structure, but also allows us to estimate the amount of water bound to DNA. Upon dehydration of the DNA film, changes characteristic of the B-A transition were observed in the IR absorption spectrum. Using thermogravimetric analysis, it was shown that the degree of DNA hydration reaches the saturation level at a relative humidity of 60% and decreases slightly upon further drying. It has been established that with increasing Na+ concentration, the amount of water strongly bound to DNA decreases. Along with it, sodium ions destroy the hydration shell of DNA and are able to interact directly with phosphate groups.

This research investigates 24 647 non-homologous protein sequences. The occurrence profile of peptapeptides was constructed for every sequence and hierarchically organized elements of various sizes were revealed by a special mathematical method in each profile. The correlations between these hierarchical elements were analyzed and it was shown that in a tested set of protein sequences there are 11 levels of protein organization with elements ranging in length from 7 to 56 amino acid residues. It was suggested that the identified levels of organization correspond to elements of a super-secondary structure with different topology.

Quantitative analysis of cytokines, chemokines, growth factors and other soluble proteins in different biological liquids is routinely performed in contemporary diagnostics and biomedicine research. However, current methods of analysis are time-consuming and include multiple steps. In this study, we have developed a protocol that describes how bio-layer interferometry can be applied to quantify an analyte in several minutes. Conditioned growth media collected from mouse mesenchymal stem cells grown in normoxia or hypoxic conditions in a monolayer fashion, MSC-derived 3D cell sheets and 3D spheroids were used as a model system in which we determined a concentration of vascular endothelial growth factor (VEGF-A). This technique displayed a high sensitivity (down to 0.1 ng of VEGF-A per mL as a minimum). The measured concentrations of VEGF-A in the conditioned media from mesenchymal stem cells turned out to be similar with values determined by the enzyme-linked immunosorbent assay. Using bio-layer interferometry, it was shown that as compared to mesenchymal stem cells grown in monolayer, spheroids and 3D sheets of mesenchymal stem cells produce significantly more VEGF-A (by 2.5-3.0-fold). Thus, due to the developed protocol it was possible to adapt bio-layer interferometry for rapid quantification of growth factors in conditioned media.

We showed that the mouse monoclonal antibodies directed against the beta isoform of heat shock protein 90 (Hsp90beta) bind specifically to Hsp90beta found on the surface of tumor and untransformed cells. After binding to membrane-associated Hsp90beta, antibodies actively dissociated into the culture medium and were internalized by cells. An immunoconjugate prepared on the basis of the Hsp90beta-specific antibody and the cytotoxic agent mertansine did not exhibit high cytotoxic activity against tumor cells in vitro. The injection of the Hsp90beta-specific antibody into mice did not influence the growth of primary tumor of epidermoid Lewis lung carcinoma but suppressed the metastasis of tumor in the lungs and increased the mean life span of mice. The results suggest a certain therapeutic potential of antibodies directed against Hsp90beta for tumor therapy.

Authors: Ziliwu Boby Wisely
Published: October 2020

Refrigeration is an attempt to maintain the temperature level of a material or room at a level lower than the temperature of the surrounding environment by absorbing heat from the material or room. In short it can be said that refrigeration is the process of transferring heat from a material or another room. Basically, refrigeration technology is heat treatment. The refrigeration process is inseparable from the cooling load problem during the refrigeration machine operates. Excessive cooling load on a refrigeration unit will certainly have an effect that can accelerate the process of decomposition or deterioration in the quality of the catch. This research aims to calculate the cooling load of the blast freezer water and determine the refrigeration components of the blast freezer water unit. From the research results obtained, that the ship whose refrigeration system has a cooling power of 30 kW is able to cool fish as much as 3.5 tons (3,500 kg). With a cooling load of 1 ABF space of 28.54 kW with a fish mass of 3,500 kg. the COPactual achieved by the blast freezer water is about 2.8 smaller than the COPcarnot of 6.1.

Published: October 2020

This study attempts to answer the question of how a narrow (9-ft) lane dedicated to Automated Vehicles (AVs) would affect the behavior of drivers in the adjacent lane to the right. To this end, a custom driving simulator environment was designed mimicking the Interstate 15 smart corridor in San Diego. A group of participants was assigned to drive next to the simulated 9-ft narrow lane while a control group was assigned to drive next to a regular 12-ft AV lane. Driver behavior was analyzed by measuring the mean lane position, mean speed, and mental effort (self-reported/subjective measure). In addition to AV lane width, the experimental design took into consideration AV headway, gender, and right lane traffic to investigate possible interaction effects. The results showed no significant differences in the speed and mental effort of drivers while indicating significant differences in lane positioning. Although the overall effect of AV lane width was not significant, there were some significant interaction effects between lane width and other factors (i.e., driver gender and presence of traffic on the next regular lane to the right). Across all the significant interactions, there was no case in which those factors stayed constant while AV lane width changed between the groups, indicating that the significant difference stemmed from the other factors rather than the lane width. However, the trend observed was that drivers driving next to the 12-ft lane had better lane centering compared to the 9ft lane. The analysis also showed that while in general female drivers tended to drive further away from the 9-ft lane and performed worse in terms of lane centering, they performed better than male drivers when right-lane traffic was present. This study contributes to understanding the behavioral impacts of infrastructure adaptation to AVs on non-AV drivers.

Nutrition is responsible for most of the production costs and the formulation of balanced diets is of paramount importance to provide better productive performance and greater economic efficiency. Thus, the emergence of industrial amino acids allowed the elaboration of diets based on the ideal protein, providing an amino acid profile closer to the animals' needs, improving the use of nutrients and decreasing the excretion of dietary nitrogen in the environment. In view of the benefits presented using the ideal protein concept in the formulation of diets, this review aimed to show its application in poultry and swine nutrition
Variety and its quality in energy-saving tomato production technology
Authors: Velizhanov N.
Published: October 2020

Abstract. In the 21st century, the share of the variety in the formation of the size and quality of the crop will increase from 20-40 to 70 % or more. It is obvious that the role of the variety increases significantly not only in increasing productive, but also medium-improving functions of agrophytocenosis, including soil-improving, phytosanitary, bioenergy, design – aesthetic, etc. A lot of attention is paid to the appearance, texture, taste properties of fruits, which increase their dietary value and overall attractiveness to buyers. Methods. The research was carried out at the experimental site of the Federal Agricultural Research Center of the Republic of Dagestan in 2017–2019. In production conditions, 12 widely used varieties of tomato have been tested in the seedling culture in recent years. The samples were studied using the ACIRO methodology and the State Crop Testing Methodology. Results. Promising varieties with high adaptability and stability in extreme conditions of the flat zone of the republic have been revealed. We have established morpho-anatomical and physiological changes in varieties of stamp forms, which determine their reduced, compared to the unstamable forms of resistance to drought, which significantly inhibit production processes in dry years. The most economic was the cultivation of varieties with high yields of standard fruits - Mariana, Mirage, F1 Andromeda. The cultivation of the Hussar variety cost 1.6 times more than F1 Andromeda. The cost of obtaining 1t standard harvest for other varieties was significantly higher. Scientific novelty is to study the sign of a reduction in the duration of the growing season in the combination of the size and yield of fruits on the biochemical composition, taste and technological, which is overcoming negative bonds, or to achieve a compromise combination. In the process of creating new ones and testing them, these evaluation criteria should be decisive.

Published: October 2020

Abstract. Potato is an important food and industrial crop, occupying one of the leading places in the world production of crop products. Its tubers contain all the necessary nutrients: carbohydrates, proteins, vitamins, essential amino acids, organic acids, mineral salts. Potato is traditionally the second most important crop product in the Russian Federation after grain crops. In terms of production, Russia occupies one of the leading places in the world in terms of the gross harvest of potato tubers (10 % of the world volume), but in terms of productivity it is significantly inferior to all the leading potato growing countries of the world. Methods. To increase the yield and quality of the products obtained, it is of great importance to optimize the area for feeding potato. The studies were carried out on the experimental field of the educational and experimental farm “Uralets” of the Ural State Agrarian University (USAU), the village “Studencheskiy”, for three years (2016–2018) in the climatic zone of the Middle Urals. Purpose of research. The purpose of the research is to study the influence of the feeding area of Gala potato, the use of fungicides on the yield and quality of tubers in the Middle Urals. Gala potato variety, feeding area and fungicides were taken as the object of research. Scientific novelty. The scientific novelty of the research lies in the fact that for the first time in the conditions of the Middle Urals it was established that the highest yield of all the studied options was obtained with a feeding area of 2450 cm2 (70 × 35 cm) using the fungicide Shirlan 36.6 t/ha (factor B), which is 31.1 % higher than control (factor A) with HCP05 = 0.79. Results. In experiments in the variant with a feeding area of 1400 cm2, the largest leaf area from 1 hectare was 27.47 thousand m2 and the maximum photosynthetic potential was 2.03 million day m2/ha. It is economically efficient to plant potato tubers in the developed technology with the use of the fungicide shirlan in the variant with a feeding area of 2450 cm2 (planting scheme 70 × 35 cm), where the lowest cost price (4446 rubles/t), the highest profit (269 172 rubles/ha) and the highest profitability were obtained (165.43 %).

Abstract. Hedysarum gmelinii is a perspective species for the introduction into the culture and further use in the agricultural industry and pharmacology. The purpose of this research is to find suitable medium for seed germination. At present, this species is under the threat of extinction in several subjects of the Russian Federation. That is why research of the optimal nutrient medium for the seeds of H. gmeliniiis very relevant. Materials and methods: 100 pcs of mature seeds were selected from the populations of Tatarstan and Bashkortostan. The seed material had been stored at the 4°C before it was used. The Murashige and Skoog (MS) medium was prepared under the protocol with adding of such plant hormones like 6-benzylaminopurine (BAP) and Indole-3-acetic acid (IAA) in four types of concentrations. After that the sterilized seeds were planted. The germination was occurred at 20 °С and the daylight was 16 hours. The results: seeds started to grow up to 15th day of an experiment. Then the plants were transferred on the fresh medium. Young plants were formed after 13 days. Plants which seeds had been taken in Tatarstan showed the most active callus formation. Thus, the originality of this research is that the optimal medium for growing seeds of Hedysarum gmelinii in vitro was found. This medium ensures good viability and gives the opportunity to get the tissues culture for the further studies of the biologically active substances.

Published: October 2020

Abstract. The purpose of the study is to analyze and evaluate creative innovative technologies for personnel management of agricultural enterprises in the context of macroeconomic instability and uncertainty. The object of the study. The development of innovative technologies is an important condition for the formation of creative management of the personnel of enterprises. In the context of the transition to a new technological structure and the modern scientific and industrial revolution, fundamentally new technologies for human resource management arise and develop. Modern society is a society of a new type, a “risk society” (W. Beck). Therefore, creative management includes not only innovative approaches to solving the problems of personnel policy, but also new technologies for working with risks. In the context of growing macroeconomic instability and uncertainty, creative personnel management is a risk-oriented practice of recruiting, placing and organizing the work of specialists, developing their professional qualities. Methods. The study used the methods of structural-functional, program-target and comparative analysis. The subject of the research is new technologies of risk-oriented creative personnel management of agricultural enterprises. The object of the research is the personnel management system as an integral element of the system of social and labor relations. Results. The main factors of macroeconomic instability and uncertainty are identified. A detailed classification of existing personnel risks is given. The features are revealed and the practice of new technologies of personnel management is analyzed (blockchain, crowdstaffing, crowdfunding, crowdsourcing, etc.). The difficulties of adapting creative technologies of personnel management to modern conditions are shown. The thesis about the expediency of developing the practice of labor self-government at modern enterprises is argued. Scientific novelty. The author's interpretation of the essence of creative personnel management is formulated and reasoned, and its difference from innovative management is revealed. Shown is the most important manifestation of the creativity of personnel management associated with the management of personnel risks in the context of macroeconomic instability.
Metrological characteristics of measuring laser power divider

Published: October 2020

An analysis of the errors of the measuring optical power divider of laser radiation, which is used to transmit a unit of average power of high-intensity laser radiation and is structurally made in the form of a wedge, is carried out. The error of the division ratio, which affects the accuracy of the unit transmission, is determined. The estimation of the random component of the division coefficient error is carried out and it is shown that the proposed method for its determination, based on the rearrangement of the used measuring instruments, gives the most probable estimate. The error caused by the nonlinearity of the measuring instruments that determine the division coefficient is investigated, and its largest interval is estimated. It is shown that in the case of invariability of the conversion coefficients of the used measuring instruments on the laser radiation power, the method makes it possible to exclude the dependence of the error in determining the division coefficient on the mentioned coefficients, and in another case, to reduce their influence on the transmission error. The possibility of controlling the division factor of the divider by determining the control parameter and its confidence interval when transmitting a unit of radiation power is substantiated; a formula for calculating this interval in each measurement cycle is obtained. It is shown that the value of the parameter and the change in the confidence interval can be used to control the reliability of the transmission of the unit of power to the calibrated measuring instrument in real time.

Com a premissa de que o ambiente de empreendedorismo e inovação das incubadoras tem seus resultados otimizados quando se há uma gestão eficiente da criação, transferência, fluxo e aplicação do conhecimento, esta pesquisa teve como objetivo efetuar um estudo de caso da Ativa Incubadora de Empresas do IFMT para diagnosticar como se encontrava em relação as práticas de Gestão do Conhecimento e elaborar propostas de intervenção de acordo com o resultado. Foi aplicado um questionário na Gerência Executiva na incubadora, assim como em seus núcleos que se encontravam constituídos por todo o estado de Mato Grosso em 2019. Percebeu-se que embora a maioria dos gestores dos núcleos não tivesse familiaridade com esse tipo de gestão, há uma percepção abrangente das práticas, entretanto, de forma pouco intensificada e muito defasada em alguns casos, como as práticas de banco de competências individuais, banco de competências organizacionais e sistema de gestão por competências. Como proposta de intervenção, sugeriu-se utilizar as práticas que já funcionam relativas à transferência do conhecimento para a socialização entre os núcleos que já possuem uma implantação efetiva e que geram resultados e aqueles que ainda se encontram defasados.
Impacto do convívio intergeracional na socialização de idosas institucionalizadas
Authors: Gonçalves Marizete , Truccolo Adriana Barni
Published: October 2020

A institucionalização da pessoa idosa pode ser uma situação estressante uma vez que leva ao distanciamento da família e amigos e, consequentemente, ao isolamento social. Nesse contexto, o convívio com pessoas de diferentes gerações, ao mesmo tempo que propicia situações desafiadoras, proporciona troca de experiências e criação de vínculos estimulando a socialização. Dessa forma, surgiu a seguinte questão de pesquisa: Qual o impacto do convívio intergeracional na socialização entre idosas institucionalizadas e crianças? O objetivo geral é investigar o impacto provocado pelo convívio intergeracional na socialização entre idosas institucionalizadas e crianças. Foi realizado em uma instituição de longa permanência de idosos (ILPI), com 15 idosas e duas crianças. Os dados foram coletados a partir da observação participante e sistemática registradas em um diário de campo. A pesquisa aconteceu de março a dezembro de 2018, uma vez por semana, e contemplou dois momentos, a observação da rotina das idosas e as intervenções propriamente ditas. Foram realizadas quatro observações e vinte e cinco intervenções. Identificou-se que as atividades que mais favoreceram o convívio intergeracional foram aquelas em que as crianças explicavam às idosas, como a pintura, o desenho, e os jogos de tabuleiro. Constatou-se que sentimentos de amizade, solidariedade para com as limitações, respeito às diferenças, confiança e apego foram construídos ao longo dos meses. As idosas manifestaram maior autoconfiança e segurança, e as práticas de intervenção intergeracional promoveram momentos de aprendizagem mútuos, afastando das crianças qualquer pensamento preconceituoso a respeito da velhice. Idosas e crianças fazem parte de grupos vulneráveis, possuem rotinas, horários, e talvez esses pontos em comum as aproxime. O convívio intergeracional teve um impacto positivo sobre a socialização entre as idosas institucionalizadas e as crianças.

Published: October 2020

A Lei 12.305, de 02 de agosto de 2010 que instituiu a Política Nacional de Resíduos Sólidos estabeleceu novas diretrizes aos municípios brasileiros quanto à destinação final adequada destes materiais, no entanto, os gestores municipais veem enfrentando grandes dificuldades para o atendimento à Lei, pois a mesma é ampla, complexa, com vários fatores envolvidos, requerendo o empenho de altos valores para implantação e operação. Partindo deste contexto, o objetivo deste artigo foi analisar a aplicação das políticas públicas implantadas pelo Governo Municipal para o atendimento da Política Nacional de resíduos Sólidos no Município de Gurupi, Tocantins. Constata-se que a coleta de resíduos sólidos no município tem boa funcionalidade e a gestão municipal busca melhorias para aperfeiçoar o processo, porém esbarra no quesito financeiro. Quanto ao Aterro Sanitário de Gurupi, o mesmo possui deficiências na operacionalidade e dificuldades de atendimento à totalidade das demandas da Lei 12.305/2010, em contrapartida é bem conceituado pela Fundação Nacional da Saúde, demonstrando-se ser referência no estado. Dessa forma o presente artigo apresenta o diagnóstico da situação atual operacional dos resíduos sólidos no município de Gurupi.
¿Qué fue de la unión bancaria europea?
Authors: Sánchez Barrios Rocío
Published: October 2020

El impulso para la creación de la unión bancaria constituyó una respuesta política de gran calado y una solución técnica e institucional a la crisis financiera de 2008 sin precedentes en este ámbito. Ocho años después del acuerdo político que impulsó el proyecto, la unión bancaria es una realidad en lo que a su pilar de supervisión y resolución se refiere, a pesar de los importantes retos que ambos marcos enfrentan a futuro. La ausencia de avances, sin embargo, en el pilar correspondiente a la cobertura de depósitos y las otras piezas hoy identificadas como relevantes obliga a hablar de una unión bancaria incompleta.
Análisis de la Unión Europea como modelo de negociación
Authors: Verdeguer Puig Enrique
Published: October 2020

Una de las características de la Unión Europea es la permanente necesidad de alcanzar objetivos a través de la negociación. La heterogeneidad de los Estados miembros, tanto desde un punto de vista económico, como social e institucional, hace que la consecución de resultados creíbles, sostenibles y que sean satisfactorios para todas las partes, no sea una cuestión sencilla. El presente artículo trata de analizar cuáles son las condiciones necesarias para que las negociaciones puedan maximizar el beneficio conjunto y para que el interés común de la UE se anteponga a las posiciones de las partes, en la línea de lo que propone el modelo de Harvard de negociación.

I riflessi del rischio sanitario da COVID-19 sul trasporto marittimo di persone
Authors: Romagnoli Alessandra
Published: October 2020

Il rischio emergenziale connesso alla diffusione della sindrome da COVID-19 e le misure governative di relativo contenimento hanno determinato particolari conseguenze giuridiche sulla regolare esecuzione del contratto di trasporto marittimo di persone, anche sotto il profilo della tutela della posizione giuridico-patrimoniale del passeggero. Lo studio, nel compiere un'indagine comparativa del disposto di cui all'art. 88-bis del d.l. 17 marzo 2020, n. 18, dalla quale emergono significative deviazioni rispetto alle regole eurounitarie ed alle previsioni codicistiche che sarebbero risultate ordinariamente applicabili, si propone di esaminare l'incidenza dei provvedimenti autoritativi di gestione dell'emergenza sanitaria sulla conservazione del contratto, sulle forme di tutela dei diritti dei passeggeri e sul regime di responsabilità vettoriale.

Contratti di locazione turistica e per locazione turistica
Authors: Cuffaro Vincenzo
Published: October 2020

Muovendo dalla messa a fuoco della nozione di "locazione turistica", l'analisi dei testi normativi emanati nel periodo dell'emergenza consente di esaminare gli effetti che l'epidemia, bloccando l'attività turistica, ha determinato sui contratti di locazione legati al turismo. L'esame è condotto in una duplice prospettiva: la sorte di contratti di locazione conclusi dal turista, per i quali è esplicito lo scioglimento per impossibilità sopravvenuta; le vicende delle locazioni concluse in vista della successiva locazione turistica, per le quali possono essere adottati rimedi diversi, diretti a governare il sopravvenuto squilibrio delle prestazioni.
Navigare nell'emergenza: crociere e COVID-19
Authors: Lopez de Gonzalo Marco
Published: October 2020

Il settore delle crociere è stato duramente colpito dall'epidemia COVID-19. Le conseguenze di tale epidemia devono essere valutate in base alla direttiva (UE) 2015/2302 ed alla legislazione nazionale di emergenza. L'operatore di crociere può essere responsabile nei confronti dei passeggeri che siano stati contagiati a bordo; la responsabilità può essere evitata con la dimostrazione di avere adottato tutte le ragionevoli cautele. Il programma della crociera può essere sostanzialmente modificato; l'operatore di crociere deve predisporre alternative, ma ciò può risultare difficile in pratica. Le crociere possono essere cancellate, dall'operatore o dal passeggero; dovrebbe essere fornito un rimborso integrale ed è dibattuto se tale rimborso possa essere sostituito da un voucher.

Il dispositivo gruppale di psicoterapia transculturale con le famiglie migranti nell'esperienza della Cooperativa Crinali
Authors: Finzi Ida
Published: October 2020

A partire dai principi dell'approccio dell'etnopsicoanalisi, viene descritta in questo lavoro un'esperienza ormai pluriennale di terapia transculturale di gruppo per famiglie migranti. Si tratta di un servizio pubblico al quale le famiglie vengono inviate da parte dei servizi territoriali. Il gruppo è composto da una terapeuta principale, un'interprete, alcuni coterapeuti e mediatrici linguistico-culturali. Il gruppo è multiculturale e la terapia si svolge in madrelingua e in italiano. Si descrivono i principi ispiratori, il setting, le tecniche utilizzate, e le finalità terapeutiche orientate principalmente all'accoglienza e alla valorizzazione dell'alterità culturale e all'elaborazione dei meccanismi di scissione presenti a seguito del trauma migratorio.
Al di là di ciò che posso vedere con gli occhi
Authors: Sireci Maria Grazia
Published: October 2020

Un viaggio attraverso le opere della mostra itinerante e interattiva: Don't Ask Me Where I'm From, toccando alcuni temi comuni nel percorso di vita dei migranti di seconda e terza generazione. La mostra invita il visitatore/viaggiatore a fare un vero e proprio viaggio all'interno e fuori di sé, facendo risuonare delle corde personali che parlano di aspetti fondamentali nella vita di ciascun individuo; punti di riferimento, senza i quali difficilmente potremmo vivere una condizione di benessere.Temi dunque come la casa, la memoria e la lingua prendono forma attraverso il colore o il bianco e nero, le linee o gli spazi vuoti e tanto altro. L'arte rende giustizia a ciò che questi artisti hanno vissuto o stanno vivendo e permette un approdo simbolizzante, un ponte tra noi e loro.
