We Were There
Authors: Fryer-Moreira Raffaella
Published: March 2021

The popular uprising in Brazil between 2013 and 2014 led to the emergence ofmidiativistas,media activists who produced audiovisual testimony from the front lines of protests. Their reports were grounded in their act of ‘being there’ and bearing witness, and the affective encounters that their position made possible. Their first-hand accounts were situated, partial, and deemed more convincing because they rejected the mainstream media’s claims to ‘objective truth’ – as a view from everywhere that is simultaneously a view from nowhere (and no-one) – in favour of situated truth, witnessed directly, unsettling traditional divisions between representation and reality, and questioning the conditions (and relations) through which knowledge is produced. This ethnographic engagement with the knowledge practices of others, and the role of witnessing within them, reflects on anthropological knowledge practices more broadly, and how they may be conceived otherwise in light of empirical variants from our fields.
The Anthropologist’s Video Camera as Stage
Authors: Hänsch Valerie
Published: March 2021

In this article, I explore how Sudanese communities have attempted to visually document, witness and communicate a silenced history of forced displacement. Thousands of peasants in rural Northern Sudan were flooded out of their homes along the Nile during the 2003–2009 Merowe Dam construction project. My aim is to examine both the complex local interactions with and appropriations of the anthropologist’s video camera, which, in the relational process of witnessing, turned into a stage to provide audio-visual evidence against hegemonic discourses of Sudan’s successful hydroelectric future. I show how my video camera’s affordances of capturing and mediating ‘truth’ evoked specific performative genres of representation in moments of crisis and illustrate how these usages differ from everyday interactions with a video camera. These performative genres of ‘crisis witnessing’, I contend, resonate with globally distributed media realities and thereby reproduce certain practices of communication that are stereotyped in the mass media.
The Aesthetics and Publics of Testimony
Authors: Çaylı Eray
Published: March 2021

Physical environments and their images feature increasingly prominently today in efforts to contend publicly with political violence, making aesthetics ever-significant to discourses and practices of testimony. Critics have shown that the publicness of the platforms and practices used in these efforts is marked by disparate levels and types of participation and agency. Relatively underexplored, however, is how those disadvantaged by this disparity navigate it and what role aesthetics may play therein. I explore these questions through fieldwork on architectural memorializations of the 1993 Solingen arson attack where a family with Turkish background were targeted at home in their sleep. I argue that the arson attack has featured in these memorializations not simply as the subject of testimony but also as a force structuring its aesthetics.
Witnessing the Unseen
Authors: Chua Liana
Published: March 2021

This article draws on two research projects – one on orangutan conservation, and the other on religious change among indigenous Bidayuh communities – to reflect on the relations, technologies and processes involved in producing witnesses and witness-able truths. I compare two forms of witnessing: visualizations of environmental crisis and orangutan extinction, and modes of encountering invisible entities among Bidayuhs. Both involve the challenge of making the unseen visible or apprehensible and thus addressable. But whereas the first entails a crisis-laden visual imaginary that turns witnessing into a form of human stewardship over the environment, the second involves a more relational encounter involving mutual adjustment and responsivity to obligations and commitments. I suggest that this latter mode of witnessing invites us to reimagine both the crisis logic of environmental visualizations and ideals and practices of anthropological witnessing.

Te article tackles the feasibility of improving the raspberry fruit size as an important production and marketability factor. Te trials included 22 domestic and foreign cultivars, 11 selected forms of raspberry, as well as ten cross-breeding combinations and three open-pollinated forms. Te assessment of parental forms and hybrids was carried out at the collection and breeding sites of the Kokino base station of Federal Horticultural Center for Breeding, Agrotechnology and Nursery during 2016-2020. Fruits were harvested from regular cultivar bushes every 2 days in triplicate. Te average weight was determined per 100 berries in each replicate. Cultivars and hybrids were divided into three groups, small- (3.6 g). Te average berry weight in hybrid nurslings was estimated per plant. Each plant was sampled with 30 berries. Weighing was performed with an SCC-750 electronic scales device. Te weather conditions of the trial period were contrast, allowing a more objective assessment of the collection and breeding raspberry material by berry weight. Te following cultivars were identiﬁed as the sources of improved berry size in the parental form trials: Maria, Cascade Delight, Fenomen, Lavina, Cowichan, Patricia, Laczka, Glen Ample and selections 2-115-1, 8-13-2, 18-11-3, 18-11-2, 2-90-2 and 2-90-3. Tese forms had an average trial-period berry weight of 3.7-4.3 g least aﬀected by weather conditions. Te inspection of hybrids revealed the best parental forms for obtaining new raspberry cultivars with an improved berry weight: Maria, Fenomen, Lavina, Cowichan, Glen Ample and the selected form 8-13-2. Te promising cross-combinations are: 2-12-1 x Fenomen, Lavina x Ulybka, 8-13-2 x Peresvet, as well as the open-pollinated oﬀspring of Glen Ample, Cowichan and Maria. Large-fruited genotypes isolated in these lineages will be used in further breeding to increase the fruit size in raspberry.
How Engineering Technology Students Perceive Mathematics

Published: March 2021

Engineering Technology (ET) is often combined with that of Engineering. Although Engineering Technology is based on a more hands-on approach and Engineering a theoretical approach, the two majors share a very similar pedagogy in teaching students the same engineering and scientific principles. An observation by an ET professor found that ET students more often than not would eschew the use of mathematical computations and instead provide answers they believe to be correct, without computation or explanation. Leading researchers to delve into possible reasons as to why ET students are reluctant to utilize mathematics. This study utilized in-person interviews with 15 undergraduate participants from a Midwestern University in the United States of America from ET to ascertain how ET students perceive mathematics. The results of the study found that although ET students were stated to not hate mathematics and are open to using mathematics, there was a slight apprehension towards math due to bad math experiences and not being able to connect the conceptual nature of mathematics to the visual and real-life scenarios ET students are used to facing. The results of this study help to lay the foundation for future research studies geared towards further understanding why ET students are apprehensive towards mathematics and ultimately how to help ET students overcome this apprehension.

Politicisation of Administration and Implications for Knowledge Generation in South Africa : A case of a Black University
Authors: B. Shai Kgothatso
Published: March 2021

The subject of the politics of knowledge is not uniformly understood by both scholars and practitioners. Much work in this regard is based on Northern angled perspectives, which are deficient in abilities to capture the essence of African reality. On the basis of qualitative materials and interdisciplinary discourse analysis, this article’s focus is on the politicisation of university administration in South Africa. Taking cue from my previous works on this subject, I have identified and discussed additional three central factors which impair scientific knowledge generation and development in South Africa and Africa as a whole. Among others, these factors include bureaucratisation of academic administration, academic jealousy and gangsterism and shortage of academic role models. Theoretically and in order to foster epistemic justice, this study has drawn from Afrocentricity as an alternative contextual lens to paint a qualitatively rich picture of the phenomena under study.
Transforming the Public Sector through ICTs : Content Analysis of the E-Government Websites of the Ministries of the Government of Lesotho
Authors: Matsieli Molefi , Sooriyamoorthy Radhamani
Published: March 2021

E-government has been proposed as an ICT strategy and a tool to reinvent government and transform the public sector. However, most of the existing literature on transforming the public sector through ICTs in Lesotho assessed e-government at the national level through the National Government Web Portal. This paper evaluates the current status of the websites of the ministries of the Government of Lesotho concerning their maturity levels to deliver e-government services and allow government-citizens interaction. The evaluation is based on a content analysis of four ministerial websites. The results show that the websites of the ministries of the Government of Lesotho are at the infancy stages of e-government implementation, clearly delaying the realisation of the government objective to transform government and the public sector through the use of innovative technologies. It is recommended that the government addresses both technical and social obstacles impeding web-based e-government implementation.
Rescaling the Weather Experience: From an Object of Aesthetics to a Matter of Concern
Authors: Diaconu Madalina
Published: March 2021

This paper analyses the cluster of aesthetic features involved in the common experience of the weather. Perceptual features (framelessness, chromatics, texture, synaesthesia, ephemerality, proteism) are accompanied by ‘atmospheric’ moods that are irreducible to physiological well-being. Representation and imagination reach their limits due to the more-than-human spatiotemporal scale of the atmosphere. Finally, some ‘transaesthetic’ aspects include the agency of an active matter and the longing for an elemental alterity. The aesthetics of the weather has to account for the interdependence between aesthetic and ethical values, between bodily engagement and appropriate knowledge, individual contemplation and social commitment, in order to develop ecological responsibility.
Development of effective methods and means of normalizing the atmosphere of working zones of open-cast mines
Authors: Nalyvaiko V. , Konovaliuk V.
Published: March 2021

The search for technical solutions for effective air exchange in the space of deep open-cast mines. Since intensive air exchange is necessary to remove and disperse harmful impurities from the open-cast mines, improvement can be achieved mainly by intensifying natural air exchange based on phase transformations of liquids in the lower atmosphere of the working zones of the open-cast mines by creating a positive or negative temperature gradient. New technical solutions are considered that provide support for the sanitary-hygienic parameters of the atmosphere of the deep open-cast mines at the normative level. The formation of an ascending gas stream by a cascade explosion of a fuel-air mixture has the greatest efficiency. The proposed method allows for the implementation of a pulsed ventilation mode with a power of the outgoing air flow of more than 1010 W with a blasting fuel mass of 30 tons. It has been established by analytical and experimental studies that it is advisable to use pulsed fine irrigation systems to intensify air exchange in a deep open-cast mines, using the double effect, ventilating gaseous working zones and cleaning them from harmful substances with the help of a fine aerosol freely floating in space. It is also advisable to use such facilities to reduce peak loads on emissions of harmful substances from the open-cast mines into the environment and to normalize the composition of the atmosphere of the deep open-cast mines. Significant peak emissions of harmful impurities in open-cast mines include mass explosions and situations involving the creation of internal inversion zones. In a computational experiment, there are two water guns: big gun (the water jet range is 200 m, water volume per one cycle is 1000 dm3) and small gun(the water jet range is 100 m, water volume per one cycle is 200 dm3). The results of the experiment indicate greater efficiency in the use of a large water gun for airing the lower horizons of the deep open-cast mines. The use of pulsed fine irrigation systems will allow for carrying out internal technological work at a depth of more than 500 meters using a motorized ore delivery system to transfer points of cyclic-flow technology.

Published: March 2021

The article researches the behavior and limit state of thin-web bedI-beams with transversal corrugations under patch loading action. Web local stability analysis was performed on beam models, which had been created according to standard corrugated profiles range of company Zeman. Numerical analyses on physical and mathematical models and experimental investigations on two physical models with similar to them parameters and steel were executed.

The critical stress analyses were carried out via the finite elements method (FEM) with the assumption of steel elastic behavior accounting both geometric linearity and geometric nonlinearity. The calculation shows that taking into account the elastic behavior of steel the geometric nonlinearity has insignificant effect on the results.

Two buckling forms (local and general for thicker webs) were ascertained while investigating the stability loss of web. The critical loading's value increases with increasing of purlin’s supporting length, but the web's critical stress decreases. But for all models critical stresses value is almost similar (tolerance is less than 0.36%) to steel yield strength fy= 305MPa.

The numerical and experimental investigation results of corrugated web behavior under patch loading are presented. Established that model’s bearing capacity does not fail after reaching by theoretical and experimental normal stresses the ultimate strength of the web steel, and ultimate loading increases by 35 – 40 % due to the stress’s redistribution in the web along the length.

The results of calculations and experiments certificates that when the strength requirement specified by Eurocode No. 3 is met the corrugated web’s bearing capacity will be alwaysensured.

Authors: Lizunov Petro , Nedin Valentyn
Published: March 2021

The results of numerical investigation of shafts transverse oscillations with account of gyroscopic inertia forces are presented. It is shown what the action and how the gyroscopic forces influence on the transverse oscillations of the shafts during rotation. The study has been done with computer program with a graphical interface that is developed by authors. The process of numerical solution of the differential equations of oscillations of rotating rods using the method of numerical differentiation of rod's bend forms by polynomial spline-functions and the Houbolt time integration method is described. A general block diagram of the algorithm is shown. This algorithm describes the process of repeated (cyclical) solving the system of differential equations of oscillations for every point of mechanical system in order to find the new coordinates of positions of these points in each next point of time t+Dt. The computer program in which the shown algorithm is realized allows to monitor for the behavior of moving computer model, which demonstrates the process of oscillatory motion in rotation. Moreover, the program draws the graphics of oscillations and changes of angular speeds and accelerations in different coordinate systems. Defines the dynamic stability fields and draw the diagrams of found fields. Using this program, the dynamics of a range of objects which are modeled by long elastic rods have been studied. For some objects is shown that on special rotational speeds of shafts with different lengths, in the rotating with shaft coordinate system, the trajectories of center of the section have an ordered character in the form of n-pointed star in time interval from excitation to the start of established circular oscillation with amplitude that harmoniously changes in time. It is noted that such trajectories are fact of the action of gyroscopic inertia forces that arise in rotation.
Model of high-speed shock interaction with compatible type
Authors: Kovtun Anatolii , Tabunenko Volodymyr , Nesterenko Serhii
Published: March 2021

In connection with military operations, the issue of developing protection for military personnel against bullets and splinters remains an issue. Modern studies of the interaction of bullets and fragments with protective obstacles are based on the search for new types of structures and materials of protection. The focus is on the development of NATO-compliant protective structures to increase the level of protection for military personnel using low-cost, affordable materials with minimal production and intended use.
Despite some advances in the study of solid-body impact, the known results of theoretical and experimental studies do not describe the overall picture of the interaction of the element of damage and interference. When designing protective structures, only certain aspects of the shock interaction are considered, based on the absorption of the kinetic energy of the element of damage. Therefore, it remains important for the scientific and technical task - to continue the study of the process of interaction of bullets (fragments) with protective obstacles, at the stages of penetration, penetration and their departure, which will allow to develop new models of protection structure of military personnel that are relevant for military use.
The main method of studying the process of striking and punching an obstacle with a bullet (fragment) is a combination of analytical and experimental studies. Analytical methods of research are based on mathematical modeling of stages of interaction of bullets (fragments) with elements of a protective obstacle with the subsequent carrying out of corresponding mathematical calculations. Experimental research methods are based on determining the level of security and require complex research in laboratory and polygonal conditions. The combination of analytical and experimental research results makes it possible to consider the level of security more fully.
In this work the process of interaction of a ball (fragment) with the protective obstacles formed by a set of hollow cylinders of compatible type is considered. Models for determining the depth of penetration of the impactor into the obstacle in the form of a set of hollow cylinders of compatible type are proposed. The results of calculations of the depth of penetration of the ball from Kalashnikov (AK-74) in steel hollow cylinders of compatible type are presented. Further research is concerned with improving the design of armor by developing new technical solutions using the latest technologies.
Algorithm for reducing computational costs in problems of calculation of asymmetrically loaded shells of rotation
Authors: Dzyuba Anatolii , Safronova Inha , Levitina Larysa
Published: March 2021

The problem of calculating the shells of rotation of a variable along the meridian of rigidity under asymmetric loading is reduced o a set of systems of one-dimensional boundary value problems with respect to the amplitudes of decomposition of the required functions into trigonometric Fourier series.
A method for reducing the number of one-dimensional boundary value problems required to achieve a given accuracy in determining the stress-strain state of the shells of rotation with a variable along the meridian wall thickness under asymmetric load. The idea of the proposed approach is to apply periodic extrapolation (prediction) of the values of the decomposition coefficients of the required functions using the results of calculations of previous coefficients of the corresponding trigonometric series, thus replacing them with some prediction values calculated by simple formulas.
To solve this problem, we propose the joint use of Aitken-Steffens extrapolation dependences and Adams method in the form of incremental component, which is quite effective in solving the Cauchy problem for systems of ordinary differential equations and is based on Lagrange and Newton extrapolation dependences.
The validity of the proposed approach was verified b the results of a systematic numerical experiment by predicting the values of the expansion coefficients in the Fourier series of known functions of one variable.
The approach is quite effective in the calculation of asymmetrically loaded shells of rotation with variable along the meridian thickness, when the coefficients of decomposition of the required functions into Fourier series are functions of the longitudina lcoordinate and are calculated by solving the corresponding boundary value problem. In this case, the approach allows solving solutions of differential equations for the amplitudes of decompositionin to trigonometric series only for individual "reference" harmonics, and the amplitudes for every third harmonic can be calculated by interpolating their values for all node integration points of the corresponding boundary value problem. This significantly reduces the computational cost of obtaining the solution as a whole.
As an example, the results of the calculation of the stress-strain state of a steel annular plate under asymmetric transverse loading are given.
Сalculation of maintenance of surface drainage roofing of a German manufacturer
Authors: Tetiana M. Tkachenko  , Ivan O. Prokopenko
Published: March 2021

With the help of some green technologies, such as green roofs, quantitative and qualitative indicators of rainwater can be successfully adjusted. The big advantage of green roofs is the accumulation of moisture, which allows to delay the runoff of storm water, unloading the sewer system and preventing floods. However, an arbitrary increase in accumulated water in a standard green roof structure is not possible, because more amount of moisture can adversely affect vegetation. However, this option is available in the rainwater system on the green roof as an addition to other landscaping systems. The rainwater collection system on the green roof allows to accumulate on average 80 l/m² of rainfall and then release water into the sewer system for a certain period of time (from 24 hours to several days). The purpose of the study – to study the effect of surface runoff on the environment and reduce its negative impact with the help of green roofs. The calculation of the retained surface runoff by the roof of the German manufacturer was carried out according to the original author's method (Tkachenko, T., 2019). The reservoir volume was calculated using the author's advanced Wilo methodology adapted to the climatic conditions of Ukraine. The calculation of the retained surface runoff is done by the roof of the German manufacturer ZinCo. The "green" roof is located in Kiev. The area of the roof is 150 m2. ZinСo roof has been found to be able to hold 7950 liters of rainwater and thereby to reduce surface runoff by unloading storm wells. Roof efficiency for the reduction of surface runoff reaches 21.2%, which is a very good indicator. Purified rain water from green roofs can be collected in tanks and used for technical purposes. For collecting rain water from an intensive flat roof with an area of 150 m2, a 4 m3 tank is needed for an office staff of 8 people.

Authors: Walker Benjamin F.
Published: March 2021

The George A. Smathers Libraries has a more than 60 year history of utilizing remote storage. Throughout that time, there have been drastic changes in how storage has been managed. It has historically been a somewhat opportunistic endeavor, utilizing facilities designed for other purposes and acquiring and renovating spaces as funding allowed. This article will highlight efforts by the George A. Smathers libraries to store materials remotely, with a particular focus on the 1990s on. Details of the Florida Academic Repository, including the funding proposals, shared print retention developments, and current status will be discussed. Looking back over the history of storage at UF, the George A. Smathers Libraries has invested substantial effort and money in trying to resolve these space issues, most notably with the FLARE legislative proposals. The inability to secure that funding certainly has impeded progress, but FLARE has found other ways to be an important partner in the storage and shared print movement.

Authors: Santos Natalina Moraes , Oliveira Edilson Brito de
Published: March 2021

O questionamento apresentado neste trabalho teve origem durante os estudos do curso em “Formação pela Escola” oferecida pelo FNDE (Fundo Nacional de Desenvolvimento da Educação) via Secretaria Municipal de Educação “Competências Básicas”, encontrou motivação para a sua elaboração a partir das reflexões mediante o aprendizado das Políticas Públicas na área da educação executada pelo Governo Federal, o financiamento dessas politicas e o papel do FNDE no apoio a efetivação da mesma. Compreendendo que toda classe educacional culminam de um mesmo objetivo, que é uma educação pública de qualidade a todos, resolve-se então destacar um dos impasses enfrentado pela coordenação pedagógica que, em uma visão pessoal, atrapalha a realização de tal objetivo dentro das instituições educacional quando não tratada com significância, uma vez que, este profissional precisa de autonomia, pois as atuais Politicas Públicas Educacionais e alguns princípios administrativos gerenciais acabam comprometendo ao que tange no processo de gestão do trabalho da coordenação dentro das instituições escolares, principalmente nos aspectos que exprime relação ao controle das ações docentes e ao alcance do resultado de um Ensino de Qualidade.

La tubercolosi (TB) è una malattia infettiva causata da batteri patogeni. Il bacillo si trasmette principalmente attraverso il meccanismo della tosse, oltre agli starnuti e alla parola, responsabili del rilascio di goccioline di saliva. In Brasile, nel 2017 sono stati confermati 69.569 nuovi casi di tubercolosi. Nello stato brasiliano di Amapá, sempre nel 2017, sono stati segnalati 237 nuovi casi di tubercolosi. L’obiettivo di questo lavoro è confrontare la percentuale di casi confermati di tubercolosi in Brasile, nella regione del Nord, nello stato di Amapá e nel comune di Macapá, tra gli anni 2013 e 2017. I dati sono stati raccolti sul sito web DATASUS. Anche le coinfezioni, l’alcolismo, l’uso di droghe, gli agglomerati urbani e lo stato nutrizionale dell’individuo possono rappresentare fattori che aumentano i casi di tubercolosi. Anche la vulnerabilità sociale e la scarsa assistenza sanitaria di base favoriscono un aumento di questi numeri. Avere un Centro di riferimento per le malattie tropicali (CRDT), che include anche il Centro di test e consulenza (CTA) e Assistenza domiciliare terapeutica (ADT) aiuta a rilevare i casi, razionalizzare e controllare il trattamento dei pazienti. Gli uomini in età lavorativa sono più colpiti a causa della loro interazione sociale necessaria per il lavoro.
