Witnessing the Ruins: Speculative Stories of Caring for the Particular and the Peculiar
Authors: Drew John , MacAlpine Kelly-Ann
Published: July 2020

Educational scholars and practitioners are confronting long-held anthropocentric pedagogical practices as well as notions of care. To trouble the notion of care, this article draws from the collaborative research that stories the collective experiences of children, educators, and researchers at an early years learning centre located in an emerging suburban enclave of a mid-sized city in southwestern Ontario, Canada. Our work is guided by the question of how we as educators and scholars reclaim and augment the politics of care. Through the practice of storying everyday encounters, we explore how emerging and precarious relations with more-than-human others, both real and imaginary, challenge anthropocentric notions of care.

Entre os termofixos existentes no mercado, encontra-se o polietileno reticulado (PEX), que é utilizado no encapsulamento de fios de alta tensão. Nesse processo, uma grande quantidade de resíduos é gerada e descartada, onerando a produção e prejudicando o meio ambiente. Desse modo, este trabalho propôs a modificação química do PEX por meio de reações de sulfonação, que consistem na introdução de grupos SO3H em sua estrutura. Estudou-se a influência da pré-irradiação em micro-ondas, do tempo de reação e da concentração de SO3 livre no ácido sulfúrico fumegante por FTIR-ATR, DRX e ICP. Pelos resultados obtidos verificou-se que PEX-SO3H pode ser classificado como uma resina fortemente catiônica. Os melhores resultados foram obtidos com 30 minutos de reação e 65% de SO3 livre sem pré-irradiação em micro-ondas. Apesar da avaliação econômica não ter sido satisfatória, esse estudo abre novas possibilidades para a reciclagem de termofixos.Entre os termofixos existentes no mercado, encontra-se o polietileno reticulado (PEX), que é utilizado no encapsulamento de fios de alta tensão.

Published: July 2020

Neste trabalho foi estudado o uso da lignina-peroxidase para remoção de 2-clorofenol em efluente líquido. Foi proposta a biorremediação enzimática por processo descontínuo de efluente contendo 20 mg/L de 2-clorofenol, utilizando concentrações de lignina-peroxidase (LiP) entre 0,012 e 0,026 mg/mL e de peróxido de hidrogênio (H2O2) entre 10 e 50 mmol/L, 30ºC e pH igual 4,2. Foram realizados 4 ensaios sendo coletadas amostragens para os tempos de reação de 2, 4, 8 ,12 e 24 h. Análises cromatográficas revelaram 96,5% de redução do 2-clorofenol quando empregadas concentrações de 0,026mg/mL de LiP e 50 mmol/L de H2O2. Resultados eficazes foram observados somente após 24h de tratamento, independente das concentrações de LiP e H2O2. Análises via CG/MS revelaram possíveis formações de benzaldeído e ácido ftálico e confirmou-se o consumo praticamente total de todo o 2-clorofenol após 24 horas de tratamento na condição ideal.

Os escoamentos podem ser caracterizados como: escoamento laminar ou turbulento; uniforme ou transiente e compressível e incompressível. O número de Reynolds é uma grandeza adimensional que caracteriza o movimento de fluidos, sendo definido pela razão entre forças inerciais e forças viscosas. O presente trabalho teve como objetivo utilizar um experimento didático da disciplina de Laboratório de Engenharia Química, especificamente Mecânica dos Fluidos, para evocar os seguintes estes conceitos vistos em sala de aula, bem como: a) diâmetro hidráulico; b) número de Reynolds; c) vazão mássica e vazão volumétrica; d) velocidade média do escoamento; (e) equação da continuidade, e visualizar os diferentes regimes de escoamento: laminar, transição e turbulento. A observação experimental possibilitou uma classificação do escoamento coerente com aquela dos cálculos. Neste experimento, foi confirmada, matematicamente pela análise de propagação de incertezas, usando o programa EES,  a contribuição significativa da medida do volume de água nos valores dos erros experimentais. O efeito da temperatura e a contribuição de sua incerteza também foram verificados na determinação do número de Reynolds.

Challenges for Ukraine’s cyber security: National dimensions
Authors: Katerynchuk Pavlo
Published: July 2020

The usage of information as a weapon in the foreign and domestic policies of Russia is not a new phenomenon. Still, the sophistication and intensity of it grow with each passing year. Recently the EU and USA have realized the powerful latent influence of Russian media and propaganda, including on electoral processes and the activities of State administration. They have realized that Russian disinformation poses a serious threat to the United States and its European allies, first and foremost with regard to Poland, the Baltic States and Ukraine. Moreover, unlike Soviet propaganda, the modern methods of the Russian information war do not rudely promote the agenda of the Kremlin. Instead, they aim to confuse, daze and divert citizens from supporting the EU and Ukraine. Russia seeks to undermine the support for European values; producing disarray among European allies in order to increase its influence. Ethnic, linguistic, regional, social and historical contradictions and stereotypes are used for this purpose. As current experience shows, Russian advocacy efforts in Europe make up an important part of their hybrid approach to the projection of force. Despite the fact that the crisis in Ukraine for the first time drew the attention of the West to the importance and real meaning of the information campaign in Russia, the Kremlin’s use of disinformation was launched long before the crisis. Russia carefully and purposefully prepared an information war against Ukraine.
ENERVADAS, DE MME. CHRYSANTHÈME: UM SIMULACRO AUTOBIOGRÁFICO
Authors: Fortes Maia Mariana
Published: July 2020

Mme. Chrysanthème (1870-1948) foi presença recorrente nos periódicos das primeiras décadas do século XX, publicando inúmeras resenhas, crônicas e alguns de romances. Entretanto, caiu em completo esquecimento: eis o destino costumeiro das mulheres escritoras que contrariavam, em alguma medida, as expectativas do público masculino. Impulsionados pela recente reedição de Enervadas (2019), destrincharemos alguns dos traços inovadores de sua obra, dentre os quais a estrutura bipartida que nos conduz a um simulacro autobiográfico seguido por um diário ficcional. Trata-se de um livro em que a protagonista, Lúcia, transforma-se em uma obra de arte, performando uma existência artificiosa que subverterá as noções de gênero. Estamos diante, portanto, de um duplo movimento: um romance, ficcional por excelência, é também ficcionalizado pela sua narradora. O corpo de Lúcia é um quadro e suas atitudes são sempre calculadas para atingir determinado efeito. Este estudo, igualmente bipartido, pensando nos gêneros que a obra pretende simular, busca compreender as motivações de tão entediada personagem que age de acordo com os postulados pela burguesia para dela debochar. Pretendemos, ainda, demonstrar a modernidade que há em suas subversões, perfeitamente coerentes com o temperamento enervado da personagem.

Prawo ochrony konsumenta usług finansowych w świetle założenia racjonalnego ustawodawcy — kilka wybranych uwag
Authors: Rutkowska-Tomaszewska Edyta
Published: July 2020

Akty prawa unijnego i krajowego regulujące usługi finansowe coraz częściej mają charakter kompleksowy, gdyż zawierają nie tylko normy dotyczące prawnych warunków dopuszczalności ich wykonywania przez instytucje finansowe, ale także normy regulujące w sposób szczegółowy prawa i obowiązki umów o usługi finansowe, szczególne uprawnienia konsumenta i inne mechanizmy oraz instrumenty jego ochrony, co może budzić wątpliwości. Tworzą one konsumenckie prawo rynku finan-sowego (prawo ochrony konsumenta usług finansowych) i niewątpliwie może to rodzić wiele sporów na etapie stosowania i interpretacji tego prawa i przyczyniać się także do ograniczania skuteczności przewidywanych przez te regulacje prawnych mechanizmów ochrony konsumenta usług finansowych. Celem niniejszego opracowania jest wskazanie specyfiki tego prawa oraz podkreślenie konieczności jego właściwego stanowienia, stosowania i egzekwowania.
Rozwód według procedury khula w prawie egipskim
Authors: Sadowski Mirosław
Published: July 2020

Artykuł stanowi analizę egipskiego prawa rozwodowego według procedury khula, ze szczególnym uwzględnieniem ustawy nr 1 z 2000 roku. Autor stara się wykazać, że uchwalenie tego prawa było krokiem milowym na drodze do równouprawnienia kobiet w prawie małżeńskim. Poprzednie rozwiązania prawne uzależniały uzyskanie rozwodu z inicjatywy żony od spełnienia przez nią szeregu przesłanek lub zgody męża. Nowatorstwo rozwiązań wprowadzonych ustawą nr 1 z 2000 roku polega na tym, że rozwód nie jest uzależniony od zgody męża lub sędziego. Jest on raczej uzależniony od rezygnacji przez żonę z roszczeń finansowych wobec męża przysługujących jej zgodnie z szariatem, które wynikają z kontraktu małżeńskiego lub przepisów prawa.
Jednostronnie profesjonalne umowy pośrednictwa handlowego a regulacja kodeksu cywilnego o umowie agencyjnej i umowie zlecenia — uwagi na tle wybranych umów
Authors: Wójtowicz Ewa
Published: July 2020

Umowy o świadczenie usług pośrednictwa handlowego — podobne do umowy agencyjnej — są powszechnie zawierane w obrocie handlowym. Istnieje potencjalnie możliwość stosowania do takich umów przepisów kodeksu cywilnego o umowie zlecenia. Jednakże istnieje wiele elementów, które sprawiają, że takie umowy są zbliżone raczej do umowy agencyjnej niż do umowy zlecenia. W konsekwencji należy rozważyć stosowanie przepisów kodeksu cywilnego o umowie agencyjnej, jednak przy uwzględnieniu okoliczności, że niektóre z tych przepisów są charakterystyczne wy-łącznie dla umowy agencyjnej, w tym regulacja związana z dwustronnie handlowym charakterem umowy agencyjnej oraz związana z kreowaniem przez umowę agencyjną długoterminowej relacji między stronami.

The relevance of the problem is due to the requirement of pedagogical theory and practice in ensuring professional self-development of a future primary education teacher and the existing imperfection of modern technological means of supporting professional self-development of a future primary education teacher in a digital educational environment. The information support of professional self-development of the future primary education teacher in the digital educational environment is considered. A theoretical review of the concepts of “information educational environment” and “digital educational environment” is also presented. The closest, in the context of the study, is the definition of a digital educational environment, as a combination of digital educational technologies, means and related resources that ensure the educational process in the context of society digitalization. The informational means of implementation were the technologies of pedagogical support of professional self-development of the future primary education teacher, which were substantively modernized: “Time Management” technologies, projects, web quests, modeling, foresight technologies, discussions, project technologies, various social and moral practices, modeling and gamification of future professional strategies, technology of achievements and success (competitions, olympiads). In the framework of this work, we substantiate a new scientific direction in the field of the theory and methods of professional education, substantiating both theoretical and applied solutions to the important problem of pedagogical support of the process of professional self-development of a future primary education teacher in accordance with the requirements of federal state educational standards of higher education, as well as the standard of profession “Teacher”.
Teaching translation from Chinese to Russian by means of blog technology on the example of economic discourse
Authors: Malankhanova Antonina E.
Published: July 2020

Today, the relevance of use of modern information and communication technologies (wiki-technology, blogs, podcasts, linguistic corpus), which have didactic features and methodic functions, in teaching a foreign language and translation is not in doubt. The translation of economic discourse from Chinese into Russian is in demand in the context of the expanding interaction of the two countries in the trade and economic sphere. In this connection, the need for training highly qualified specialists in translating economic discourse is growing. We present suggestions on teaching students how to translate economic discourse from Chinese into Russian language on example of using blog technology. When translating and teaching, it is necessary to take into account the difference in the organization of the structures of the Russian and Chinese languages. The listed types of modern information and communication technologies can meet the requirements for teaching translation from Chinese, which is structured as an isolating type. The focus is on the translation competencies development (linguistic, text-forming, communicative, technological competence, as well as special competencies, including economic component), based on the developed system of exercises. An algorithm is presented for organizing teaching translation of economic discourse from Chinese into Russian through blog technology, highlighting three main stages (preparatory, practical, and final) and a detailed description of the actions involved.
Psychological and pedagogical conditions for the development of pragmatic competence of students based on corpus technologies
Authors: Zolotov Pitirim Y.
Published: July 2020

We present an analysis of the concept of “pedagogical conditions”. On the basis of a comparative multi-aspect analysis of the concept of “conditions”, we determine the concept of “pedagogical conditions” and the main characteristic features are identified. We analyze pedagogical conditions in the work as an integral part of the pedagogical system; they reflect environmental opportunities that affect the personal and technological aspects of the system, contributing to its successful functioning. We consider various groups of conditions that ensure the effective functioning of the pedagogical system. We reveal the features of three groups of pedagogical conditions (organizational and pedagogical, psychological and pedagogical, didactic). Further, we propose psychological and pedagogical conditions aimed at the development of pragmatic competence based on corpus technologies. The first proposed psychological and pedagogical condition is the motivation of students to develop pragmatic competence based on corpus technologies. The second psychological and pedagogical condition is the development of foreign communicative competence in students not lower than level B1. The third psychological and pedagogical condition for the formation of pragmatic competence based on corpus technology should include the development of information and communications technologies competency in students. The following psychological and pedagogical condition for the development of pragmatic competence based on corpus technology is the formation of information and communications technologies competency in the teacher. And the last psychological and pedagogical condition for the development of pragmatic competence based on corpus technologies should be considered as following by students the designated algorithm for the development of pragmatic competence based on corpus technologies.
On the issue of business discourse in the multilingual space of Kazakhstan
Authors: Sarsenov Murat A. , Tumanova Ainakul B.
Published: July 2020

The work is devoted to the analysis of business discourse operating in the multilingual space of Kazakhstan, a multinational state where official bilingualism is present, and paperwork is conducted in two languages: Kazakh and Russian (Constitution of the Republic of Kazakhstan, Law on Languages in the Republic of Kazakhstan). Particular attention is paid to the identification of certain language units and the textual features presented in the texts of this discourse. Since 2007, along with the process of implementing the national and cultural project on the trinity of languages in the Republic of Kazakhstan, documentation, business communication and training are conducted in three languages: Kazakh, Russian and English. This generally affects the formation of the language environment of modern Kazakhstan – real business bilingualism is impossible without a parallel knowledge of the Kazakh and Russian languages, Kazakh and English. Taking into account the used methods of description, generalization, systematization and business texts contextual analysis, we make an attempt to study the linguistic features of business discourse as one of the most important types of verbal communication at the moment, which is not characterized by a personality component. We analyze the text of the order “On the Approval of Typical Curricula of Military Educational Institutions Subordinate to the Ministry of Defense of the Republic of Kazakhstan” and the sections of the text “Typical Curriculum of Military Educational Institutions Subordinate to the Ministry of Defense of the Republic of Kazakhstan for the Technical and Vocational Education Specialties Group “Military Science and Security”.

Introduction: Self-efficacy in avoiding free sex and HIV/AIDS will have an impact on adolescent sexual behavior. As well as the increasing of their self-efficacy, their sexual behavior will be more healthier. This study was aimed to determine the correlation between self-efficacy in avoiding free sex and HIV/AIDS with adolescent’s sexual behavior.Method: This was correlational study with cross-sectional approach. The populations were adolescents aged 17-19 years in Senior High School at Blitar City. Total samples were 127 respondents, taken by using simple random sampling technique. Independent variabel was self-efficacy in avoiding free-sex. Dependent variable was adolescent sexual behavior. Data were collected by using questionnaires. Data were then analyzed by using univariate and bivariate analysis with Spearman-rho test.Result: The results showed a low category of self-efficacy (magnitude, generalizability, the strength of belief), and the adolescent sexual behavior (knowledge, attitudes, and actions) in the risk category. Self-efficacy in avoiding free sex and HIV/AIDS correlate significantly with adolescent sexual behavior (p=0.000; r = -0.448).Conclusion: It can be concluded that there is a significant and quite unidirectional relationship between self-efficacy in avoiding free sex and HIV/AIDS with adolescent sexual behavior. Future research iexpected to be able to examine other factors that influence the increase in self-efficacy in avoiding free sex and HIV/AIDS, to reduce the rate of risky sexual behavior in adolescents.

The Mann-Whitney U Test showed differences in the level of emotional control in the treatment group and the control group (p = 0,000) and there were differences in blood pressure between the treatment group and the control group (systolic blood pressure p=0.004 and diastolic blood pressure p = 0.064).Conclusion: Listening to Al-Qur'an Murottal can have a positive impact. So Nurses can provide Al-Qur'an Murottal listening interventions for patients with hypertension that control patients' anger and suppress blood emotions.
Technological innovation promoters, service quality practices and performance of SACCOs in Kenya
Authors: Otii Leonard Omondi , Lawrence Kenneth , Omondi Humphrey
Published: July 2020

The programmed co-operative enterprises’ innovation initiatives in Kenya have been below their expectations of customers. The majority (60%) of the customers are satisfied by banking and related financial services offered by co-operative enterprises in Kenya. This is below the expectations of what the customers perceive and what is realized at the point of service delivery. This study sought to provide insights into the relationship between technological innovation promoters and performance by empirically testing the direct effect of technological innovation promoters on performance and exploring the moderation effects of service quality practices. The study is anchored on the promoter theory and collective entrepreneurship concept. The study used a self-administered questionnaire to Chief Executive Officers of 158 Savings and Credit Co-operative Societies (SACCOs). Data were analyzed by employing Statistical Software for Social Sciences (SPSS) Version 22 and structural equation modeling using AMOS version 25. The hypotheses were tested using structural equation modeling and hierarchical moderated multiple regression (MMR). Overall, the study found out that, technological innovation promoters have a positive influence on the performance of SACCOs in Kenya, and service quality practices (R2 change) is 0.153. This implied that the moderating effect of service quality practices gained 15.3% variance in the SACCOs above and beyond the variance by technological innovation promoters and performance. This study concludes that an integrative model comprising of technological innovation promoters, service quality practices and performance is a sure way of enhancing collective entrepreneurship and recommends that SACCO management together with their partners should deliberately nurture a customer relationship management culture that will enable them to realize positive performance that has been influenced by service quality practices

Published: July 2020

Inventarisasi sumberdaya mineral adalah kegiatan pencatatan, penggambaran, perekaman, pengambilan dan manajemen data serta informasi sumberdaya mineral, baik data primer maupun sekunder, yang diperoleh dari hasil kegiatan eksplorasi. Data dan informasi yang dikelola dalam kegiatan inventarisasi didapatkan dari proses bisnis Sistem Informasi Eksplorasi (Exploration Information System - EIS), yang terdiri dari tiga tahapan, yaitu input, pengelolaan, dan pemutakhiran data.  Penulis telah mengembangkan dua versi sistem perekaman data EIS, yaitu MODA-AWA Versi 1.0 (berbasis dBase) dan Versi 2.0 (berbasis MS-Access).  Kedua versi ini dijalankan single-user secara offline di komputer stand-alone.  Sejalan dengan perkembangan teknologi dan kebutuhan praktis di lapangan, Penulis mengembangkan Versi 3.0. Versi ini dikembangkan dengan mengoptimalkan fitur yang dimiliki Form online dan diintegrasikan dengan Aplikasi Sistem Informasi Geografis, dengan mempertimbangkan standar yang diatur dalam regulasi  dan pedoman yang berlaku di Indonesia. Pada saat awal pengembangan MODA-AWA Versi 3.0 ini, data lokasi didapatkan berdasarkan koordinat yang terdapat pada gadget. Namun dari beberapa kegiatan percobaan di lapangan, koordinat yang terbaca pada gadget kurang akurat dan presisi bila dibandingkan dengan koordinat yang didapatkan dari GPS.

A Toca do Paraguaio, assim como outros doze sítios do Holoceno antigo, localizados no Parque Nacional Serra da Capivara, no sudeste do Piauí, apresentam conjuntos culturais que atestam uma multiplicidade de comportamentos arcaicos datados entre 12 e 8 mil anos BP. Assim, com o objetivo de identificar similaridades e diferenças nesses comportamentos, bem como promover uma correlação entre os sítios datados desse período, realizou-se um levantamento de dados na bibliografia disponível, na documentação antiga relativa aos sítios e em observações diretas nos conjuntos arqueológicos, o que levou ao estabelecimento de um quadro preliminar cronocultural do Holoceno antigo no sudeste do Piauí.ARCHAEOLOGICAL CONTEXT OF THE PARAGUAYTOUCH AND ANCIENT HOLOCENE OCCUPATIONS IN SOUTHEAST PIAUÍ, BRAZIL ABSTRACTThe Paraguaio rockshelter, as well as a set of twelve other sites dated to the Early Holocene and located in Serra da Capivara National Park in the southeast of Piauí, present cultural assemblages that attest to a multiplicity of archaic behaviors between 12 and 8 Kyr BP. Thus, in order to identify similarities and differences in these behavioral aspects, as well as to promote a correlation between the different sites on the southeastern border of the Parnaíba Basin, a data collection was done in the available bibliography, in the old documentation related to the sites and through direct observations in the archaeological records, which led to the establishment of an Early Holocene chronocultural preliminary framework for the southeast of PiauíKeywords: Early Holocene; Paraguaio rockshelter; Holocene Cultures; Lithic Industry; Rock-art; Funerary behavior

Published: July 2020

A região de Palestina de Goiás, localizada no Sudoeste do Estado de Goiás, abrange cerca de 42 sítios arqueológicos registrados, sendo 28 com pinturas rupestres. Esse patrimônio cultural vem sofrendo degradação por vários fatores, e um deles é a bioturbação por cupins. Diante da importância de levantar dados que subsidiem ações de proteção e preservação da arte rupestre nessa região, o objetivo deste trabalho foi identificar a presença de cupins e suas ações nos sítios arqueológicos com pinturas. A Bioturbação por cupins foi confirmada nos seis sítios e representam uma ameaça para as pinturas rupestres. Nasutitermes foi o gênero mais frequente (59%). Os resultados subsidiam futuros estudos de monitoramento e ações de conservação em sítios arqueológicos com este tipo de ameaça.BIOTURBATION BY TERMITES (BLATTODEA, ISOPTERA) IN ROCK-ART SITES IN THE ARCHAEOLOGICAL REGION OF CAIAPÔNIA, CENTRAL BRAZILABSTRACTThe Palestine region of Goiás, located in the southwest of the state of Goiás, has about 42 registered archaeological sites, 28 of them with cave paintings. This cultural heritage has been degraded by several factors, and one of them is the presence of termites. Given the importance of protection and preservation of rock art in this region, a study was proposed to identify the presence of termites and their actions in archaeological sites with paintings. Of the 42 sites, six were visited. Termite Bioturbation was confirmed at the six sites, posing a threat to cave paintings. Nasutitermes was the most frequent genera (59%).

A delayed crosslinked polymer gel was developed for indepth water control in mature oilfields. The thermal gelation behavior of nonionic polyacrylamide (NPAM) and PEI was investigated, and sodium citrate (NaCit) was selected as a new retarder to prolong the gelation time. The gelation performance of NPAM/PEI gel system can be adjusted by the variation of NPAM or PEI concentration, and a quadratic model was developed by statistical analysis, which predict the gelation time of NPAM/PEI gel system. The obtained model showed high significance and good reliability as suggested by the F-ratio of 175.16 and high adjusted R-square value (0.9732). The decrease of the initial pH value of gelling solution leads to the weaker gel viscosity and longer gelation time due to the protonation of amine groups on the PEI chains. Increasing temperature resulted in higher gel viscosity but shorter gelation time. The addition of NaCit showed a good delayed gelation effect on the NPAM/PEI gel system, and the gel system in the presence of NaCit exhibited a good compatibility with injected and formation water. A dense three-dimensional structure was observed in matured NPAM/PEI/NaCit gel, and it could keep stable below 150℃. The gel system could effectively reduce the permeability (>95%) and restricted the flow of water after matured in natural cores.

The Covid-19 infodemic can be countered by scientific evidences, clear and consistent communication and improved health literacy of both individuals in need of information and those providing it. A rapid online survey was carried out to evaluate vaccine literacy (VL) skills in the general population and perceptions about candidate Covid-19 vaccines, as well as behavior and beliefs about current vaccinations. Observed VL levels were sufficiently high and consistent with previous observations - where comparable self-reported tools were administered face-to-face and paper-and-pencil - the mean functional score being =2.92, while the interactive-critical one was =3.27, on a maximum of 4. Perceptions regarding future Covid-19 vaccines, along with beliefs about vaccination, were mostly positive and significantly associated with functional and interactive-critical VL scales. Despite obvious limitations, the study confirms that rapid surveys via web are a suitable method to evaluate and trail attitudes during infectious disease outbreaks, and to assess health literacy skills about vaccination, which can be useful to adapt medical communication strategies, for a better understanding of the value of immunization.
Signal Fluctuations and the Information Transmission Rates in Binary Communication Channels
Authors: Pregowska Agnieszka
Published: July 2020

(1) Background: In nervous system information is conveyed by a sequence of action potentials, called spikes-trains. As MacKay and McCulloch proposed, spike-trains can be represented as bits sequences coming from Information Sources. Previously, we studied relations between Information Transmission Rates (ITR) carried out by the spikes, their correlations, and frequencies. Here, we concentrate on the problem of how spikes fluctuations affect ITR. (2) Methods: The Information Theory Method developed by Shannon is applied. Information Sources are modeled as stationary stochastic processes. We assume such sources as two states Markov processes. As a spike-trains' fluctuation measure, we consider the Standard Deviation sigma, which, in fact, measures average fluctuation of spikes around the average spike frequency. (3) Results: We found that character of ITR and signal fluctuations relation strongly depends on the parameter s which is a sum of transitions probabilities from no spike state to spike state and vice versa. It turned out that for smaller s (s<1) the quotient ITR\sigma has a maximum and can tend to zero depending on transition probabilities. While for s large enough (1<s) the ITR\sigma is separated from 0 for each s. Similar behavior was observed also when we replaced Shannon entropy terms in Markov entropy formula by their approximation with polynomials. We also show that the ITR quotient by Variance behaves in a completely different way. (4) Conclusions: Our results show that for large transition parameter s the Information Transmission Rate by sigma will never decrease to zero. Specifically, for 1<s<1.7 the ITR will be always, independently on transition probabilities which form this s, above the level of fluctuations, i.e. in this case we have sigma<ITR. Thus, we conclude that in a more noisy environment, to get appropriate reliability and efficiency of transmission, Information Sources with higher tendency of transition from the state no spike to spike state and vice versa should be applied.

The maturity of tomato fruit is normally characterized by external color and it is often difficult to know when fruit have achieved commercial maturity or become over-mature. The internal structure of tomato fruit change during development and this study investigates the utility of nondestructive measurement of tomato fruit structure as a function of maturity using magnetic resonance imaging (MRI). The objective of this work is to use analysis of internal tomato fruit structural measurements to characterize maturity. Intact cherry tomato fruit were harvested at six different maturity stages. At each stage of maturity, the internal structure of the fruit was measured using a series of 2D magnetic resonance (MR) images. Qualitative and quantitative image analyses were performed to correlate internal fruit structure with maturity. Internal structural changes observed in the pericarp region of the tomato fruit are highly correlated with fruit maturity. MR image information combined with classical analysis techniques provides a more complete understanding of structure and physicochemical changes in tomato fruit during maturation. This study demonstrates that MRI is a useful analytical tool to characterize internal changes in agricultural produce as the produce matures. This technique can be applied to almost any agricultural produce to monitor internal physical changes due to external impact, maturity stage, variation in climate, storage time and condition or other factor impacting quality.
