The Cadastre with Respect to the Integrated System of Real Estate Information
Authors: Konieczna Jadwiga
Published: September 2017

The strength of each country is determined by two factors, namely the economy and efficient administration. One of the instruments allowing the administration to perform its tasks is a fully operational system of real estate information, which meets the requirements commonly imposed on the systems of spatial information. This includes such prerequisites as: the reliability of up-to-date information issued from the system, easy access to this information, and ensuring the protection thereof. An effective real estate management system is largely determined by an efficiently operating Cadastre, an institution with a century-old tradition, to which the legislator has assigned specific tasks, and which provides the basis for specific decision-making actions associated, inter alia, with the real estate market. The aim of the paper is to present the scope of work carried out in Poland as part of the development of the Integrated System of Real Estate Information (Polish: Zintegrowany System Informacji o Nieruchomosciach, ZSIN), and the possibilities for the use of existing information systems with a particular emphasis on cadastral data. The paper defines the tasks, principles and functions of the Cadastre, as well as the indicated direction of changes allowing the Cadastre to be adjusted to the proper operation of the ZSIN.

Authors: Kuźma Marta , Lisowski Marcin
Published: September 2017

This paper presents the application of digital terrain model in developing a relief model. The digital terrain model served as the basis for the relief model. The research has taken into account the subject of combining different data in order to develop a numerical model of the land − surveying, bathymetry, maps. Another issue addressed was the one of vertical scale or exceeding it in the developed model. Its appropriate selection allows the correct representation of the terrain geomorphology. The paper presents research in carrying out relief model of Szczesliwicki Park in Warsaw. The results show the link between the vertical scale or exceeding it and the accuracy (correctness) of relief model in large-scale descriptions. In addition, a verification of models was made with the use of a scanner that uses structural light.
Accuracy Test of Laser Tracker under Condition of Air Turbulence
Authors: Kwiecień Janusz
Published: September 2017

Laser tracking for interior industrial metrology is discussed. In this work, the effects of air turbulence on the angle of laser wave propagation is analyzed in the absence of the effects associated with other meteorological parameters (pressure, humidity) and particulate pollutants (dust, smoke). This analysis establishes the effectiveness of laser tracking under turbulent air conditions and quantification of deviations in the angular and linear accuracy from those provided by the manufacturer. An experimental setup and associated measurement method to determine the turbulence structure coefficient are described. It was found that turbulent air conditions resulted in a radical decrease in measurement accuracy. The reduction in accuracy was evidenced by a decrease in power and an increase in standard deviation of the laser beam, as well as a decline in the angle and distance measurement precision. The experimental measurements show a high correlation to predicted values.

Published: September 2017

The analysis of the need for agricultural land consolidation in villages of the commune of Sławno was performed to identify villages in which adjustment interventions were needed most urgently. The factors indicative of the urgency of land adjustment were selected on the basis of a comprehensive analysis of the natural, social, economic and financial conditions characterizing the investigated villages. The analysis was carried out on the basis of data obtained from the Register of Land and Buildings of the District Office in Opoczno and the Office of the Commune of Sławno. The study allowed us to determine the surface area of land requiring urgent consolidation and exchange, thus providing grounds for applying for funds for the implementation of the proposed land adjustment scheme. Calculations were done on the basis of 19 factors (x1– x19) belonging to five groups of characteristics describing each of the investigated villages. The results expressed in the form of a synthetic measure calculated for each village allowed us to prioritize consolidation interventions. The priority ranking obtained was compared with another ranking performed using the zero unitarization method (ZUM).

Residential and public buildings are one of the essential energy consumers. The majority of European buildings
were constructed within the period from mid-1950ies to the late 1990ies. Currently the retrofitting process is too slow. The
main barriers are complicated retrofitting process, variety of available technologies as well as precision of estimated energy
savings calculations. This paper is prepared in scope of work done within the European Regional Development Fund project
“NEARLY ZERO ENERGY SOLUTIONS FOR UNCLASSIFIED BUILDINGS”. The main aim of this study is to develop
full modular retrofitting process based on 3D laser scanning minimizing time consumed for architectural project development,
on-site construction works as well as to ensure correct energy simulation. Paper presents results of Latvian case building 3D
scanning results, architectural project development specifics as well as selection of optimal thermal insulation layout and energy
simulations. Study analyses main barriers for wide implementation of prefabricated panels.

Authors: Lapinskienė Vilūnė , Motuzienė Violeta , Džiugaitė-Tumėnienė Rasa , Mikučionienė Rūta
Published: September 2017

Internal heat gains from occupants, equipment and lighting contribute a significant proportion of the heat
gains in an office space. Usage of ICT in offices is growing; on the other hand, their efficiency is also improving all the
time. Increasing energy efficiency in buildings have led to the situation, when new, well insulated office buildings, with
high internal gains within the working hours may cover low heating energy demand. Such buildings, even in heating
dominated countries, such as Lithuania, often also suffer from overheating during the winter heating season.
The paper presents the analysis of energy demand of the office building for various plug loads (ICT equipment) internal
gains scenarios and demonstrates its influence on buildings energy performance. Simulation results enable to conclude, that
when assessing sustainability and energy bills of the building, plug loads play a very important role. Meanwhile, assessing just
energy performance influence is very small. Energy performance certification results show, that plug loads may influence
energy performance label just for buildings corresponding A+ and A++ labels).

Published: September 2017

Decent quality of indoor air is important for health and wellbeing of building users. We live, work and study in indoors of various types of buildings. Often people are exposed to pollutants at higher concentrations than these that occur out-doors. Continual investigation of indoor air quality is needed for ensuring comfort and healthy environment. Measuring and analysis of occurrence of physical, chemical and biological factors is the first step for suggestion of optimization measures. Inside school buildings there are often inadequate indoor climate conditions such as thermal comfort parame-ters or ventilation. The aim of this study was determination of indoor environmental quality in selected offices in the building of elementary school in Slovakia. The values of operative temperature were not within the optimum range of values for the warm period of the year in one of the monitored offices. The intensity of illumination was lower in the two offices. Low levels of particulate matters were measured except the one office where permissible value was exceeded by 7.6%.

Published: September 2017

In order to reduce impact to environment, a qualitative approach of energy saving is global aspect that is
included in various forms of CO2 emissions, primary energy limitations and benchmarks in EU and member countries
policy. Exergy analysis allows expressing the quality of energy flows in comparison to ambient or other reference conditions.
Despite of this valuable information, this concept is not widely used in engineering practice. The article suggests
the calculation procedure for sessional or periodical thermodynamic (exergy) efficiency in relation to variable reference
conditions. Knowledge about defined procedures unlocks the possibility to fill up the implementation gap for building
system engineering practice where seasonal performance parameters are widely used to express efficiency. Prepared
algorithm allows determining seasonal or periodic thermodynamic efficiency of individual elements and energy transfer
chains in building energy systems. Defined calculation procedure workflow is suitable for integrated approach when
coupled heat transfer and fluid flow processes are explored in short time steps with dynamic simulation software tools.
Presented algorithm ensures result that fits in thermodynamically correct range 0-1 and helps to summarize separate
time step results. By adding duration of specific conditions, this analysis enables to identify critical peak periods and
base load conditions across operation period. The presented framework fills the gap in lack of systematic expression for
seasonal thermodynamic efficiency and suggests the process for calculation procedures workflow.
Catalog of Chinook Salmon Spawning Areas in Yukon River Basin in Canada and United States
Authors: Brown Randy J. , von Finster Al , Henszey Robert J. , Eiler John H.
Published: September 2017

Chinook Salmon Oncorhynchus tshawytscha return to the Yukon River in northwestern North America each summer, migrating to spawning destinations from the lower river to more than 3,000 km upstream. These returns support numerous fisheries throughout the basin. Despite a long history of fisheries research and management, there is no comprehensive account of Chinook Salmon spawning areas in the basin. To address this issue, we cataloged, summarized, and mapped the known spawning areas of Yukon River Chinook Salmon by using a variety of sources including published articles, gray literature, and information archived in agency databases. Most of our sources were published within the past 30 y, but some refer to observations that were recorded as long ago as the late 1800s. We classified spawning areas as major or minor producers with three indicators of abundance: 1) quantitative estimates of escapement (major producer if ≥500 fish, minor producer if <500 fish), 2) radiotelemetry-based proportions of annual production (major producer if ≥1% of the run, minor producer if <1% of the run), and 3) aerial survey index counts (major producer if ≥165 fish observed, minor producer if <165 fish observed). We documented 183 spawning areas in the Yukon River basin, 79 in the United States, and 104 in Canada. Most spawning areas were in tributary streams, but some were in main-stem reaches as well. We classified 32 spawning areas as major producers and 151 as minor producers. The Chinook Salmon spawning areas cataloged here provide a baseline that makes it possible to strategically direct abundance, biological sampling, and genetics projects for maximum effect and to assess both spatial and temporal changes within the basin.
Low Mortality of Larval Lampreys from Electrofishing, Suction-pumping, Anesthesia, and Handling
Authors: Jolley Jeffrey C. , Uh Christina T. , Silver Gregory S. , Whitesel Timothy A.
Published: September 2017

Native lamprey populations are declining worldwide. In the Pacific Northwest focus on conservation and management of these ecologically and culturally important species has increased. Concern has emerged regarding the effects of sampling and handling of lamprey, with little to no attention given to the larval lifestage. We monitored the survival of larval Pacific Lamprey Entosphenus tridentatus and Lampetra spp. after backpack electrofishing, deepwater electrofishing and suction-pumping, anesthesia, and handling. We performed survival trials on wild-caught lamprey (n = 15 larvae in each trial) collected from the Clackamas River drainage in Oregon, USA, coupled with control group trials from lamprey sourced from a hatchery (n = 10 larvae). Short-term (96 h) survival was >98% with only one observed mortality. Delayed mortality (1 wk) was observed for four individuals that had fungus; two of those were positive for the bacteria Aeromonas hyrdrophila. We recorded blood hematocrit as a secondary measure of stress. The baseline, nonstressed larvae hematocrit levels did not differ from those of fish that had undergone stress through electrofishing, suction-pumping, and handling without anesthesia. Electrofishing, suction-pumping, and anesthesia showed no short-term negative effects on larval lamprey although potential long-term effects remain unstudied. These techniques appear to provide efficient and relatively safe methods for collecting and surveying larval lamprey.
Synergising Action Research and Technology Education
Authors: Gumbo Mishack Thiza
Published: September 2017

Design process is a dominant method (backbone) for teaching the Technology Education subject in schools which demands critical and creative thinking skills. Moreover, the design process is research orientated, which could jell well with action research. This chapter explores the synergy between Technology Education and action research, and ultimately contributes a theoretical pedagogical framework which could help in teaching Technology by consciously pulling in action research principles into the design process, thus helping also to approach design process as a cyclical rather than a process.

Published: September 2017

The South African government has mandated national universities to emancipate and capacitate the teachers of the selected schools in science and technology through an Open Distance Learning (ODL) mode of which the University of South Africa form part of such as Higher Educational Institutions cohort. This chapter reports on the observations, field notes and interviews that were conducted with a group of four teachers and eight learners as a case study at Lovemore Primary School. This Community Engagement chapter focuses on teaching science and technology. In this chapter, researchers argue that focus group participants were able to give enough ideas, thoughts and points to enable the team to design an intervention programme through an Action Research approach. A developmental theory was used to underpin the study while the researcher and participants were engaged in a Community of Practice paradigm. More sessions will be planned to jointly structure the way forward and cultivate the nature of the intervention strategies.

Published: September 2017

The objective of this chapter is to narrate the initiations of sustainability lessons for inclusion within an MBA-IT Business Management Curriculum. This process is elucidated in a narrative style. Initiation of AL began in the year 2013 and improvised in 2014. ‘Trial and Error' experimentation in the year 2013, with ‘out of the box' lessons, achieved initial success with highly positive student feedback. AL was improvised in 2014 with industry visits, reflecting on corporate social responsibility and collaborations with civil society organizations. For easy comprehension of the thought process of AL iterations, it is recommended to understand Figure 1. Each AL activity is marked with year-wise sub-headings and AL reflections. For the stakeholders interested in modifying in higher education with AL, this institutional choice of sustainability and emphasis on sustainability AL is useful. Unlearning of previous social responsibility action patterns, usage of multiple intelligence, and experiential learning of social issues by IT Business students are the highlights of this chapter.
Volunteer Involvement in an Academic Camp in the Dominican Republic
Authors: Peralta Karie Jo
Published: September 2017

This chapter examines the expansion of volunteer participation in a participatory research project, which explored possibilities to enhance volunteer involvement in an academic camp operated by a non-governmental organization in the Dominican Republic. Although there are numerous studies that identify how organizations should involve volunteers, these studies typically represent an outsider perspective. Therefore, the concerns, ideas, and agency of volunteers—all of which may facilitate improvements in their participation—are often overlooked. For the purpose of this chapter, volunteers are elevated as key actors in the development of the organization. Specifically, community-based philosophy's concept of participation is applied to identify key moments in the project when the broadening of volunteer involvement was important for achieving a greater understanding of the issue of interest. The objective is to advance an appreciation of how projects with volunteer participation, albeit in fluctuating levels, can result in the co-creation and elevation of local knowledge.

Published: September 2017

Communities often lack a framework to guide research and action by which to mitigate complex socio-ecological challenges in the face of conflicting interests and poorly understood ecological and socio-political mechanisms. In an effort to provide such a framework, this article offers an approach for the systematic analysis of societal interactions with the landscape as well as for the structure and function of the ecosystem. Using an approach informed both by transdisciplinary research (TdR) and participatory action research (PAR), modeling is employed to identify trajectories of human influence on the ecosystem, which is illustrated using a case from the Negev Highlands of Israel. The approach identifies several cascades of effects, allowing diverse stakeholders to better understand the mechanisms by which human activities change the capacity of the ecosystem to support human well-being over time, as well as building capacity for stakeholder cooperation for sustainable management.
Diversity, Equity, and Inclusion for Learners With Diverse Needs
Authors: Tlale Lloyd Dan
Published: September 2017

Diversity, inclusion and equity are complex, interdependent and interlinked concepts and embedded in social justice. Diversity summarises numerous differences that exist among people. It means not only people of differing race and culture but also differing languages, religions, values, abilities, socioeconomic status, gender and any other aspect that makes people different from one another. It, therefore, recognises that each person is different even if they belong to the same ethnic group, community or family. Diversity is an evolving concept in inclusive education. While it once referred to children from different ethnic backgrounds, it now encapsulates every kind of individual difference that exists for children, families and professionals. Diversity is the celebration of difference and the acknowledgement that difference is complex and that it exists in some way for every child. Diversity refers to attributes that contribute to each person's uniqueness, such as social class, gender, occupational status, income, sexual orientation, ability, disability, religion, and education.

“Just Don't Get Too Personal”
Authors: Atwood Dana R. , Schroer Sandra E.
Published: September 2017

In this chapter, the authors explore Millennial students' perceptions of contemporary transformative teaching pedagogy. Following a review of the literature on popular transformative teaching practices, the authors share their findings from a survey of 400 students from two different colleges regarding teaching methods that students perceive distracts them from learning. The authors argue that while students appreciate many feminist teaching goals, they are distracted by some of the strategies that professors often use to accomplish these goals. More specifically, while students wish to be respected as valuable co-producers of knowledge in the classroom, a number of them claim to be distracted by the use of self-disclosure and physical movement. The authors suggest that professors may wish to revisit their strategies with the understanding that our current students' experiences with technology and family alter their expectations of faculty behavior.

Authors: Penland Jennifer (Jenny) L. , Burke Dawne Raines
Published: September 2017

For many minority, first generation, and other under-represented students at two small universities, graduation and a successful career seem almost out of reach. Lack of preparation, lack of confidence, and lack of career-focused experiential learning opportunities leave students feeling frustrated and result often in their early departure from higher education. This newly developed and piloted experiential learning educational program provides opportunities that allow students to grow and develop inside and outside the classroom. Through community building and regional partnerships—enmeshed in a visible number of academic departments campus wide—the researchers endeavored to promote engaged and active learning. Engaged, active learning encourages students' connections with college resources with diversified programming that includes (a) internships, (b) service learning communities, (c) experiential immersions, (d) undergraduate research platforms, and (e) capstone projects, all of which directly correlate with increased retention and persistence in higher education.

Authors: Turuthi David Gitau , Njagi Kageni , Chemwei Bernard
Published: September 2017

The presumed importance of technology in enhancing students' motivation may call for a profound shift in pedagogy. In an attempt to inform evidence-based practice, this study examined the influence of videos mediated instructions on students' motivation towards learning Kiswahili proverbs in a sample of secondary schools of equal ability in Nakuru County, Kenya. A Solomon Four quasi-experiment research design was used. The 436 students who participated in this study had a mean age of 16.2 years (SD = 0 .89) with a nearly equal sex distribution. The 43 five-point Likert type motivation items used were reduced into three dimensions: affective, behavioral, and cognitive by use of factor analytic methods. Regression analyses highlight equivocal effects of technology on these three dimensions of motivation while teacher experience was a notable confounder. Pre-test effects were also evident. The study has important implications for promoting more ambitious teaching methods.
A Pragmatic Characterization of Concept Algebra
Authors: Iurato Giuseppe
Published: September 2017

Taking into account the framework of denotational mathematics as seen by Yingxu Wang, in this paper the author wishes to implement a possible further pragmatic (context-depend) dimension into the algebraic structure of concept algebra. One of the main problems of software science is that regarding context-depend question of a programming language. Indeed, attention has been paid above all to syntactic and semantic dimensions of a programming language, neglecting the pragmatic one concerning context. The author has tried to face this question providing a first denotational mathematics structure taking into account a possible pragmatic dimension.

Published: September 2017

Probabilistic programming allows artificial systems to better operate with uncertainty, and stochastic arithmetic provides a way to carry out approximate computations with few resources. As such, both are plausible models for natural cognition. The authors' work on the automatic design of probabilistic machines computing soft inferences, with an arithmetic based on stochastic bitstreams, allowed to develop the following compilation toolchain: given a high-level description of some general problem, formalized as a Bayesian Program, the toolchain automatically builds a low-level description of an electronic circuit computing the corresponding probabilistic inference. This circuit can then be implemented and tested on reconfigurable logic. This paper describes two circuits as validating examples. The first one implements a Bayesian filter solving the problem of Pseudo Noise sequence acquisition in telecommunications. The second one implements decision making in a sensorimotor system: it allows a simple robot to avoid obstacles using Bayesian sensor fusion.
A Review of Congestion Control Schemes for Vehicular Ad-Hoc Network (VANET) Communication
Authors: Olotu Samuel Ibukun , Ojokoh Bolanle Adefowoke , Adewale Olumide Sunday
Published: September 2017

Intelligent Transportation Systems (ITS) are built on top of self-organizing networks, known as Vehicular Ad hoc Networks (VANET). In VANET, each vehicle equipped with communication devices represents a node and is allowed to send and receive safety messages through wireless communication channels. These messages are either periodic (beacons) or event-driven. Beacons are transmitted periodically while the event-driven messages are generated when an abnormal condition or an imminent danger is detected. The event-driven messages should be delivered to neighbouring nodes with high reliability and limit time as a single delayed or lost message could result in loss of lives. In dense network, the periodic messages broadcast lead to broadcast storm/blind flooding problem in VANETs. It is very important to keep the communication channel free from congestion in order to ensure timely and reliable delivery of event-driven safety messages. This study presents a review of existing congestion control schemes for VANETs with the aim of discussing the contributions and drawbacks of the algorithms.
Vehicular Fog Computing
Authors: Menon Varun G. , Prathap Joe
Published: September 2017

In recent years Vehicular Ad Hoc Networks (VANETs) have received increased attention due to its numerous applications in cooperative collision warning and traffic alert broadcasting. VANETs have been depending on cloud computing for networking, computing and data storage services. Emergence of advanced vehicular applications has led to the increased demand for powerful communication and computation facilities with low latency. With cloud computing unable to satisfy these demands, the focus has shifted to bring computation and communication facilities nearer to the vehicles, leading to the emergence of Vehicular Fog Computing (VFC). VFC installs highly virtualized computing and storage facilities at the proximity of these vehicles. The integration of fog computing into VANETs comes with a number of challenges that range from improved quality of service, security and privacy of data to efficient resource management. This paper presents an overview of this promising technology and discusses the issues and challenges in its implementation with future research directions.

Modern society is facing serious problems with the transportation systems given the increase in traffic jams, accidents, fatalities and CO2 emissions. Thus, improving the safety and efficiency of transportation systems is imperative. Developing a sustainable transportation system requires a better usage of the existing infrastructure, the adoption of emerging technologies (e.g. embedded devices, sensors and short-range radio transmitters) and the development of applications capable of operating in wireless and spontaneous networks. In this paper, the authors give readers a global vision of the challenges and issues related to the development of applications for vehicular ad-hoc networks (VANET). It also presents a classification of applications and an overview of the top-level application domain. In addition, it investigates the importance of information in vehicular networks and analyses the requirements for different types of vehicular applications placing them in a table which summarized the findings. Finally, the communication schemes that underpin the operation of VANET applications as well as the security threats they are exposed to are studied.

Authors: Freitas Iara Silva , Cardoso Erika Arantes de Oliveira , Santos Manoel Antônio
Published: September 2017

Espiritualidade e religiosidade constituem fontes significativas de suporte emocional e social para familiares de crianças gravemente doentes, sobretudo no caso de doenças potencialmente terminais. O transplante de células-tronco hematopoiéticas (TCTH) é um dos tratamentos mais arrojados e promissores que surgiram nas últimas décadas para doenças onco-hematológicas. Trata-se de procedimento altamente invasivo e que envolve risco de morte em decorrência de seus efeitos adversos. Por isso, exige o envolvimento intenso de um cuidador familiar durante todas as suas etapas, o que expõe esse membro da família a estressores contínuos. O objetivo deste estudo foi investigar o sentido atribuído à espiritualidade e religiosidade por mães de crianças com câncer hematológico submetidas ao transplante de células-tronco hematopoéticas. Trata-se de uma pesquisa qualitativa, de delineamento descritivo-exploratório, com fundamentação fenomenológica. Foram entrevistadas dez mães. As entrevistas individuais foram audiogravadas e, posteriormente, transcritas e submetidas à análise compreensiva dos relatos. Espiritualidade e religiosidade emergiram nas falas das participantes, coloridas pelas diferentes crenças religiosas professadas, como fonte de apoio e alento para a cuidadora familiar, auxiliando-a a suportar as adversidades inerentes à situação de ser acompanhante de paciente submetido a procedimento de alto risco. Os resultados corroboram a importância da religiosidade e da espiritualidade como recursos de enfrentamento.
ACOMPANHAMENTO TERAPÊUTICO (AT) E REFORMA PSIQUIÁTRICA: HISTÓRIA DE UMA PRÁTICA
Authors: SILVA SOUZA ANDRESSA MAYARA , PONTES SUELY AIRES
Published: September 2017

O presente trabalho versa sobre o processo histórico de consolidação do AT como prática no percurso da reforma psiquiátrica. Trata-se de uma revisão sistemática de literatura sobre o tema por meio da identificação e análise de artigos publicados nas bases de dados SciELO, PePSIC e Portal de Periódicos Capes, a partir das palavras-chave: acompanhamento terapêutico (AT) e acompanhante terapêutico (at). Como os artigos demonstram, o histórico do AT não se deu de forma linear, apresentando avanços e retrocessos em seu processo. Apesar das divergências apresentadas pelos autores em relação ao tempo de surgimento do AT, houve, nos trabalhos revisados concordância quanto aos movimentos que influenciaram o AT, sendo os principais a reforma psiquiátrica e luta antimanicomial. Após discussão dos argumentos apresentados nos diferentes artigos, conclui-se pela importância da visibilidade e promoção dessas práticas em saúde mental, de modo a afirmar o AT enquanto dispositivo clínico e político em saúde mental.
TRANSVERSALIZANDO AS POLÍTICAS PÚBLICAS: QUANDO A INTERSETORIALIDADE SE TORNA RIZOMÁTICA
Authors: Romagnoli Roberta Carvalho
Published: September 2017

Este texto discute a intersetorialidade nas políticas públicas, rede de proteção social que associa diversos setores para tornar mais eficaz o atendimento à população. Propomos, a partir das ideias de Gilles Deleuze e Félix Guattari e da prática intersetorial pensada na transversalidade da macropolítica e de micropolítica, discutir teoricamente a intersetorialidade como um rizoma, uma rede de relações que pode ser percorrida em diversas direções, possuindo estratos e invenções diversas. Entre os estratos evidenciamos o excesso de trâmites, a falta de avaliações das ações conjuntas após os encaminhamentos, a ausência de resposta de setores, a falta de conhecimento dos técnicos e a sobrecarga de trabalho. Nas possibilidades de invenção, que são singulares, encontramos alguns pontos que favorecem agenciamentos: o compromisso dos profissionais, o conhecimento das atribuições do próprio setor e dos outros setores do equipamento e o conhecimento do território. Concluímos que a prática intersetorial se faz pela conexão de diferenças em um plano de imanência.
O ESTRANHO COMO CATEGORIA POLÍTICA: PSICANÁLISE, TEORIA QUEER E AS EXPERIÊNCIAS DE INDETERMINAÇÃO
Authors: Lima Vinícius Moreira , Vorcaro Ângela Maria Resende
Published: September 2017

Judith Butler se apropria de vários conceitos da psicanálise, mas não explora o estranho (Unheimliche) freudiano. Trata-se, aqui, de investigar a função política desse conceito, considerando que a norma o converte em abjeção, como em casos de homofobia e transfobia. No encontro entre um sujeito cujo semblante sexuado é estruturado dentro da hegemonia heterossexual e um sujeito com semblante abjeto, o primeiro espera ver i(a), um outro-espelho de sua imagem narcísica, mas se defronta com a, o estranho abismo do desejo do Outro. Com Lacan, esse Unheimliche é produtor de angústia no eu do sujeito, o que faz vacilar suas identificações em uma experiência de indeterminação. Porém, nossas formas de vida sustentam ficções identitárias demasiado rígidas, que convertem essa angústia do indeterminado em medo e violência. Em certos casos de homofobia e transfobia, um sujeito com semblante normalizado vivencia de maneira improdutiva a ameaça de dissolução do seu eu frente a um estranho que é tido como abjeto, inumano, monstruoso. Torna-se crucial pensar formas de vida em que experiências de indeterminação possam ser vividas de maneira produtiva, em que identificações sejam mais porosas em relação àquilo que não se reduz à forma determinada de um eu.

The paper deals with the wear of tool electrodes for Die Sinking EDM. In the experiment were used the electrodes of copper and graphite. The workpiece material was steel EN43CrMo4. For the assessment the effects of each parameter was used the statistical method Design of Experiments (DOE). Assessed input factors were the peak current, pulse on-time, pulse off-time, and the electrode material. The result of the effects of each input factors was tool electrode wear. For calculating the relative wear of electrodes was used the percentage of the ratio of the electrode and the workpiece weight. The results show that the expression of the relative wear in practice can be described as a method unusable due to the absorption of the graphite electrode used in the experiment.

From the point of view of its design solution, the shape, the dimensions and the position of an gate have the biggest impact on the final quality of castings. The gate is where the stream of hot-melt flowing into the mould cavity is modulated, and where the speed of this stream changes, which eventually determines the loading mode of the mould cavity affecting the homogeneity of any casting, and thus its mechanical properties as well. The length of the gate for a specific type of casting is determined constantly according to the projection methodology for connecting the gate to the casting. The gate height is determined by its area to length ratio. In practice, several methods are used to determine the gate area. The presented paper deals with an assessment of particular methods of designing the gate area for a specific type of a lightweight casting on the basis of silumin produced, using die casting technology. Since the length of the gate is constant, based on particular methods for determining the area, the gate height is the variable parameter. The performed experiments focus on an assessment of permanent deformation of parts cast at certain gate heights, determined analytically according to particular calculation methods. Permanent deformation serves as an indicator of the most suitable method for the gate area calculation. At the same time, the paper specifies patterns required for the calculation of gate dimensional characteristics, since the available scientific literature only provides indicative values depending on the nature of any given casting or an alloy.
Research of the Basic Physical Regularities of Material Removal in Electrical Discharge Machining of Tool Steel

The paper describes the basic physical regularities of material removal in Electrical discharge machining (EDM) of tool steel. One of the parameters, that material removal regularities quite accurately identifies, is the tool wear rate (TWR). This parameter, however, describes only the regularities concerning the tool electrode wear. More complex parameter for assessing regularities of material removal in EDM is thus electrode wear ratio (EWR). This parameter, except the size of the wear of the tool electrode, also describes the size of the workpiece material removal. Research on material removal was carried out on samples made out of tool steel EN X32CrMoV12-28 using Cu-ETP electrode EN CW004A. Aim of this paper was also based on the selection of main process parameters that significantly influence the material removal in EDM to define the individual specifics with regard to minimizing EWR.

Histological chorioamnionitis (HCA) is an intrauterine inflammatory condition that increases the risk for preterm birth, death, and disability because of persistent systemic and localized inflammation. The immunological mechanisms sustaining this response in the preterm newborn remain unclear. We sought to determine the consequences of HCA exposure on the fetal CD4+ T lymphocyte exometabolome. We cultured naive CD4+ T lymphocytes from HCA-positive and -negative preterm infants matched for gestational age, sex, race, prenatal steroid exposure, and delivery mode. We collected conditioned media samples before and after a 6-h in vitro activation of naive CD4+ T lymphocytes with soluble staphylococcal enterotoxin B and anti-CD28. We analyzed samples by ultraperformance liquid chromatography ion mobility–mass spectrometry. We determined the impact of HCA on the CD4+ T lymphocyte exometabolome and identified potential biomarker metabolites by multivariate statistical analyses. We discovered that: 1) CD4+ T lymphocytes exposed to HCA exhibit divergent exometabolomic profiles in both naive and activated states; 2) ∼30% of detected metabolites differentially expressed in response to activation were unique to HCA-positive CD4+ T lymphocytes; 3) metabolic pathways associated with glutathione detoxification and tryptophan degradation were altered in HCA-positive CD4+ T lymphocytes; and 4) flow cytometry and cytokine analyses suggested a bias toward a TH1-biased immune response in HCA-positive samples. HCA exposure primes the neonatal adaptive immune processes by inducing changes to the exometabolomic profile of fetal CD4+ T lymphocytes. These exometabolomic changes may link HCA exposure to TH1 polarization of the neonatal adaptive immune response.

In elderly patients, bacterial infection often causes severe complications and sepsis. Compared to younger patients, older patients are more susceptible to sepsis caused by respiratory infection. Macrophage (Mϕ) phagocytosis of bacteria plays a critical role in the clearance of pathogens and the initiation of immune responses. It has been suggested that Mϕ exhibit age-related functional alterations, including reduced chemotaxis, phagocytosis, antibacterial defense, and the ability to generate reactive oxygen species. However, the mechanisms behind these changes remain unclear. The present study sought to determine changes in bacterial phagocytosis in aging alveolar Mϕ (AMϕ) and the underlying mechanisms. We show that bacteria initiate cytoskeleton remodeling in AMϕ through interaction with macrophage receptor with collagenous structure (MARCO), a bacterial scavenger receptor. This remodeling, in turn, promotes enhanced cell surface expression of MARCO and bacterial phagocytosis. We further demonstrate that Rac1-GTP mediates MARCO signaling and activates actin-related protein-2/3 complex, an F-actin nucleator, thereby inducing F-actin polymerization, filopodia formation, and increased cell surface expression of MARCO, all of which are essential for the execution of bacteria phagocytosis. However, AMϕ isolated from aging mice exhibit suppressed Rac1 mRNA and protein expression, which resulted in decreases in Rac1-GTP levels and actin-related protein-2/3 activation, as well as subsequent attenuation of F-actin polymerization, filopodia formation, and cell surface expression of MARCO. As a result, bacterial phagocytosis in aging AMϕ is decreased. This study highlights a previously unidentified mechanism by which aging impairs Mϕ phagocytosis of bacteria. Targeting these pathways may improve outcomes of bacterial infection in elderly patients.
