Published: May 2019

Hemangiopericytoma is a tumor derivated from the mesenchymal cells that surround the capillary of blood vessels. It has a several anatomic localization and clinic scenarios, it´s presentation with a media in the 6th decade; an early diagnostic and treatment represents a better clinic scenario for the patient. The next article presents a case report of a 51 years old man with a tumor localized in the sacrococcygeal space, with big dimensions that limited his daily activities without other symptomatology, image studies with no evidence of distant progression. Surgical resection was performed, removing mass depending from mayor and minor gluteus, achieving an immediate reconstruction with a satisfactory aesthetic and functional result. The authors presented this rare case due to the lack of published information and how it can be treated to achieve good results.

Stevens Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are considered a single entity with variability in the extent of the lesions, characterized by erythema multiforme that may involve mucosa. Severe cutaneous reactions secondary to medications are classified according to the area of epidermal detachment. The activation of cytotoxic T cells and macrophages is mediated mainly by IL-2 and interferon gamma secreted by Th1 lymphocytes, and the activation of eosinophils and B lymphocytes in IgE is mediated by secreted IL-4, IL-5, IL-10 and IL13 by B lymphocytes. The topography of SJS is predominantly central, affecting the trunk and sometimes a generalized dissemination is shown that affects a body surface area of less than 10%, characterized by irregular violaceous erythematous macules of target shooting, which can form confluent blisters. TEN is characterized by a skin detachment greater than 30% of the body surface, whose predominant lesion is diffuse erythema with individual macules, which give rise to detachment surfaces greater than 5 cm. The treatment is symptomatic, nonspecific, and aimed at avoiding complications, carried out in specialized intensive care units, due to ignorance of the pathogenesis. Integral management with different therapeutic alternatives can represent a crucial part in the multisystemic management of SJS and TEN.
What are they doing? And where? Tracking the Traffic as one of the instruments in an evidence-based redesign of a university library
Authors: Olsen Heidi Kristin
Published: May 2019

During the last decade we have seen an increased focus on the future use of academic libraries, both in terms of their legitimacy and the use of the physical library space itself.

Prior to a planned, major rebuilding of the Humanities and Social Sciences Library at the University of Oslo (HumSam library), a thorough study was required to establish the current use of the library space, as well as users’ wishes and needs for change.

Several different methods were used to collect this data. One was the method Tracking the Traffic (TTT), developed by Tord Høivik. This is a purely quantitative method, where the users in the library are counted several times during the opening hours. This registration takes place over a set period, for example, at fixed hours every day over a minimum time span of two weeks. The activities of the users are also registered, but without talking to the user, so one can register that one user is reading a book or using a laptop, but not what kind of book or what the laptop is being used for. Other methods used were a user survey, different kinds of interview and photo documentation.

This article aims at demonstrating how the use of the TTT method contributed when the HumSam library conducted studies to ensure an evidence-based renewal of the library. The experiences with this type of data collection are described, and a discussion of the methodology based on our experiences is presented.  There are also examples for how this data affected the rebuilding and renewal of the HumSam library. The TTT method needs to be a part of a suite of methods to give an adequate profile of library use. Being a method based on observation, it is necessary to compliment it with other qualitative methods to fill in the picture of library users and to ensure library development soundly based on full evidence (Evidence-based Practice – EBP).

Of course, the library staff had many pre-assumptions about the library use; however, documenting use in this way may lead to more accurate knowledge.

When visiting the redesigned HumSam library today, the responses to the results of the TTT and the other studies mentioned in this article can be clearly seen. The most obvious are the number and variation of seating facilities, the number of group rooms and the reduced height and number of shelves for the physical collection. Scenes and special places for events have also been created, opening hours in exam periods have been increased and the library counters have a more inviting design than before.

The steadily growing interest in studying of endocrine genetics is driven not only by the search for new pathologies but also by the most pressing need to develop methods for early diagnosis, treatment and management of patients. Though 20% of all the patients with von Hippel-Lindau syndrome do not have a family history of the disease; a genetic basis is a natural characteristic of the disease and determinates a phenotype. Despite the nonaggressive course, in general, a relative unpredictability of the syndrome signs onset and the lack of regular monitoring can increase the risk of surgery complications and cause a disability at a young age. The presented clinical case shows the need for a multidisciplinary approach to management of the patients with von Hippel-Lindau syndrome.
Non-Dispersive Extraction of Ge(IV) from Aqueous Solutions by Cyanex 923: Transport and Modeling Studies
Authors: Kamran Haghighi Hossein , Irannajad Mehdi , Teresa Coll Maria , Sastre Ana Maria
Published: May 2019

A transport process was studied from an aqueous solution containing oxalic acid and 100 mg/L Ge using a flat sheet supported liquid membrane (FSSLM) system. Cyanex 923 immobilized in a polytetrafluoroethylene membrane was employed as a carrier. The solution chemistry and related diagrams were applied to study the transport of germanium. The effectual parameters such as oxalic acid, carrier concentration, and strip reagent composition were evaluated in this study. Based on the results, the oxalic acid concentration of 0.075 mol/L and the carrier concentration of 20 %v/v were the condition in which the efficient germanium transport occurred. Among strip reagents, NaOH (0.04-0.1 mol/L) had the best efficiency to transport germanium through the SLM system. Furthermore, the permeation model was obtained to calculate the mass transfer resistances of the membrane (Δm) and feed (Δf) phases. According to the results, the values of 1 and 1345 s/cm were evaluated for Δm and Δf, respectively.

The Chang’e-4 (CE-4) lunar rover, equipped with The Visible and Near-IR Imaging Spectrometer(VNIS) which based on acousto-optic tunable filter spectroscopy, was launched to the far side of the moon on December 8, 2018. The detection band of VNIS ranges from 0.45 to 2.4μm. Because of the weak reflection of infrared radiation from the lunar surface, a static electronic phase-locked acquisition method is adopted in the infrared channel for signal amplification. In this paper, full-link simulations and modeling are conducted of the infrared channel information flow of the instrument. The signal/noise characteristics of VNIS are analyzed in depth, and the signal-to-noise(SNR) ratio prediction and laboratory verification are presented. On January 4, 2019, the VNIS started working successfully and acquired high-resolution spectrum data of the far side of the moon for the first time. Through analysis, the SNR ratio is in line with predictions, and the data obtained by VNIS in orbit are consistent with the information model proposed in this paper.

Proximity extension assay (PEA) is a powerful immunoassay for detection of protein molecules via DNA ligation and amplification, offering high specificity and sensitivity. Taking the advantages of PEA, we have analyzed the alteration of 92 proteins in relation with cancers with plasma samples from the volunteer subjects before and after dietary intervention with Xiangsha Taro (Colocasia esculenta Schott), an annual herbaceous perennial plant, in order to evaluate its anticancer effects. In the current study, forty-two healthy individuals were recruited and dietary intervention with 200g Xiangsha Taro daily was conducted for one month. 92 proteins related to cancer in plasma samples of all subjects before and after dietary intervention were comparatively analyzed by using Proximity Extension Assay (Oncology II). Physiological and biochemistry parameters were also examined. The altered proteins related with cancers were analyzed with GEPIA. Results indicated that CYR61, ANXA1, VIM and GZMH were found to be most significantly down-regulated after Xiangsha Taro consumption. These four proteins were found to be mainly associated with pancreatic adenocarcinoma (PAAD). Furthermore, several metabolic parameters, including the levels of globulin, albumin, creatinine, fasting blood glucose, were found to be significantly decreased after Taro dietary intervention. The current study, thereby, provides the first evidence suggesting that Xiangsha Taro may have the chemoprevention effects mainly in PAAD. Further study of the major chemical components of Xiangsha Taro and their physic chemistry functional properties in relation with anti-cancer effects has been taken into our consideration.

Easter Island (Rapa Nui) deforestation has traditionally been viewed as a single event, synchronous in time and space across the island and caused by Polynesian settlers. However, recent studies have challenged this idea introducing the concept of spatio-temporal heterogeneity and suggesting a role for climate change. This paper presents a continuous paleovegetation record of the last millennium (~960 to ~1710 CE), based on palynological analysis of a peat core from Lake Kao. During this time interval, deforestation was gradual, with three main pulses at ~1070 CE, ~1410 CE and ~1600 CE, likely driven by drought, anthropogenic practices (mostly fire) or the coupling of both. Some forest regeneration trends have been documented after the first and the second deforestation pulses. Forests were totally removed by 1600 CE, coinciding with the full permanent human settlement of the Kao area. Comparison with other continuous palynological records available for the last millennium (Aroi marsh and Lake Raraku), confirms that forest clearing was heterogeneous in time and space, rather than synchronous island-wide.

Measuring Clinical Uncertainty and Equipoise by Applying the Agreement Study Methodology to Patient Management Decisions
Authors: FAHED Robert , DARSAUT Tim E. , FARZIN Behzad , CHAGNON Miguel , Raymond Jean
Published: May 2019

Background: Clinical dilemmas in the treatment of patients translate into disagreements in decision-making. Such disagreements can reveal clinical uncertainty that should be addressed through care research. Our goal was to explore the use of reliability study methods to measure the degree of clinical uncertainty and equipoise regarding the use of rival management options prior to the conduct of randomized trials.
Methods: The study design resembles an inter-/intra-observer diagnostic reliability study. A portfolio of a sufficient number of diverse individual patients sharing a similar clinical problem and covering a wide spectrum of clinical presentations can be independently submitted to a variety of clinicians who manage that problem. Clinicians are asked to choose one of the predefined management options that are involved in the clinical dilemma. Intra-rater agreement can be assessed at a later time with a second evaluation.
Results: Descriptive statistics are presented, and results analyzed using kappa statistics. Interpretation of results can be facilitated by providing examples or by translating the results into clinically meaningful summary sentences. Reporting should follow standard guidelines.
Conclusion: Measuring the uncertainty regarding management options for clinical problems may reveal disagreements, provide an empirical foundation for the notion of equipoise, and inform or facilitate the design/conduct of clinical trials to address the clinical dilemma.

Published: May 2019

Background: The optimal approach for patients with gallbladder stones and intermediate risk for choledocholithiasis still remains undetermined. Use of diagnostic endoscopic retrograde cholangiopancreatography should be minimized as it carries considerable risk of post-procedural complications. This study compares two different management strategies: intraoperative cholangiography and endoscopic ultrasound before laparoscopic cholecystectomy for patients with symptomatic cholecystolithiasis and intermediate risk for choledocholithiasis. • Methods: It is a prospective randomized single-centre clinical trial enrolling adult patients undergoing laparoscopic cholecystectomy due to symptomatic gallbladder stones with intermediate risk for choledocholithiasis. The risk for choledocholithiasis is calculated using an original prognostic score – Vilnius University Hospital Index. A total of 106 participants will be included and randomized into two groups. Evaluation of bile ducts using endoscopic ultrasound and endoscopic retrograde cholangiography on demand will be performed before laparoscopic cholecystectomy for one arm (“Endoscopy first”). Intraoperative cholangiography during laparoscopic cholecystectomy and postoperative endoscopic retrograde cholangiopancreatography on demand will be administered in another arm (“Cholecystectomy first”). Postoperative follow-up is 6 months. The primary endpoint is the length of hospital stay. Secondary endpoints will include accuracy of the different management strategies, adverse events of interventions, duct clearance and technical success of interventions (intraoperative cholangiography, endoscopic ultrasound, endoscopic retrograde cholangiography), costs of treatment. • Discussion: This trial is planned determine which strategy is better approach for a patient with intermediate common bile duct stones risk and to define a simple to calculate and safe algorithm on managing choledocholithiasis. • Trial registration: The trial is registered at ClinicalTrials.gov, identification number NCT03658863.
Why History of Archaeology Matters?
Authors: Babić Staša
Published: May 2019

Over the last decades, in the framework of the wider critical reassessments of archaeological theory and practice, especially in the English-speaking literature, a number of writings have been published, pointing to the origins and theoretical background in which some of the basic concepts of the discipline were developed. The very essence of archaeology has thus been situated into the cultural, political and ideological context of Western Europe at the end of the 18th and beginning of the 19th century. On the other hand, by the end of the 19th century this strategy of study into the past has become a part of the academic life in other contexts (such as Serbia), where the general circumstances were utterly different. However, the basic concepts were transferred from their original setting, inevitably undergone transformations, and then applied with long-lasting consequences. Therefore, the importance of the study of the history of archaeology in various local settings surpasses local concerns, but contributes to deeper understanding of the social role and importance of archaeological research in general.
Identity Restored: Nesmin's Forensic Facial Reconstruction in Context
Authors: Anđelković Branislav , Harker Joshua
Published: May 2019

A wide range of archaeological human remains stay, for the most part, anonymous and are consequently treated as objects of analysis; not as dead people. With the growing availability of medical imaging and rapidly developing computer technology, 3D digital facial reconstruction, as a noninvasive form of study, offers a successful method of recreating faces from mummified human remains. Forensic facial reconstruction has been utilized for various purposes in scientific investigation, including restoring the physical appearance of the people of ancient civilizations which is an important aspect of their individual identity. Restoring the identity of the Belgrade mummy started in 1991. Along with the absolute dating, gender, age, name, rank and provenance, we also established his genealogy. The owner of Cairo stela 22053 discovered at Akhmim in 1885, and the Belgrade coffin purchased in Luxor in 1888, in which the mummy rests, have been identified as the very same person. Forensic facial reconstruction was used to reproduce, with the highest possible degree of accuracy, the facial appearance of the mummy Nesmin, ca. 300 B.C., a priest from Akhmim, when he was alive.
A Tentative Attempt to Estimate the Systemic Number of the Late Neolithic Vinča Culture Figurines
Authors: Porčić Marko
Published: May 2019

In this paper an attempt is made to estimate the number of figurines which were in "use" in households of the Late Neolithic Vinča culture. The number of accumulated figurines and houses is used as a starting point. Given the complexities of the settlement dynamic, figurine use and the formation processes of the archaeological record, the ratio of the number of accumulated of figurines to the number of accumulated houses is only an indirect reflection of the systemic number of figurines. Different figurine use scenarios are evaluated in order to see what the result would be. Keeping in mind that the entire analytical procedure is highly speculative and the range of tested models is far from exhaustive, the results suggest that scenarios resting on the assumption that there was a single figurine per household and that the average use-life of the figurine was equal to the average human generation length predict outcomes that are comparable to the actual archaeological situation.
Constructing Identities in the Roman Dalmatia: Gladiators of Salona and their Social Status
Authors: Janković Marko A.
Published: May 2019

Inscriptions on stone urns of the gladiators buried in the immediate vicinity of the amphitheatre in Salona offer insight into their social status. Information gained from these inscriptions testifies about the ambivalent attitude of the Roman society towards marginal groups, in this case gladiators. On one hand, these are slaves deprived of the Roman civil rights, with limited field of social action, while on the other hand the mode of burial (stone urn with inscription and image) does not differ significantly from the burials of the Roman citizens of the same period. Although gladiators were very popular, they constituted, along with actors, prostitutes and their procurers, the infames, one of the marginalized groups of the Roman society. In spite of such a social status of gladiators, the urn inscriptions speak about selected information, announced in a way that invokes a certain image – that of the gladiators’ vocation. The paper analyzes this information in order to offer insight into the preferred identity of the deceased, but as well of the ones burying them.
The Guest Worker as a Liminal Being: The Problematization and Conceptualization of Guest Worker’s Cultural Identity
Authors: Antonijević Dragana
Published: May 2019

Based on life stories of Serbian migrant workers gathered through fieldwork, we shall attempt to problematize the issue of their cultural identity which is characterized by a feeling of liminality – of not fully belonging in either environment – the country of origin nor the host country. Keeping in mind that the opposition that determines the value systems, status and worldview of migrant workers is the opposition between here and there, we will apply analysis to the cognitive cultural shema and the typical rhetorical statements, which, with certain variations, appear again and again in the narratives of migrant workers. These statements form a sort of backbone to their narratives, contributing to the creation of a cultural cognitive scheme of shared experiences among migrant workers. We shall point out and interpret several other key oppositions through which the life experience and sense of identity of our migrant workers is refracted, while noting the problems and consequences of this phenomenon, for the migrant workers themselves as well as, in the wider sense, the community they belong to in their country of origin.

This review presents the results of our own research on the informativity of new molecular biomarkers in the early diagnosis of nosocomial pneumonia, as well as modern principles for the prevention of nosocomial pneumonia. A promising direction for the early diagnosis of nosocomial pneumonia and its complications is the study of new molecular biomarkers, in particular, Clara cell protein and surfactant proteins. Effective prevention of nosocomial pneumonia should be based on a complex of modern evidence-based methods.
Images of Russians and Americans as Seen by Russian Adolescents
Authors: Marin E. B.
Published: May 2019

The present research features the image of "the typical Russian" and "the typical American" as perceived by Russian adolescents  (students of the Far Eastern Federal University). The images were  reconstructed using methods of psychosemantics, e.g. verbal  associations. The data were processed using the methods of  mathematical statistics. The semantic analysis helped to define the  ideas and emotional attitude of the respondents to "the typical  Russian" and "the typical American", as well as the semantic  contrast of the content in some categories. The Fisher criterion  revealed significant differences in the content of certain categories of associations. The stereotype displayed a predominantly positive  orientation, while the orientation of the heterostereotype was  ambivalent. The image of "the typical Russian" reflected primarily  such positive qualities as kindness, openness, and patriotism. Both  positive (activity, tact) and negative qualities (hypocrisy and lies)  were manifested in the ideas about the "typical American". The  positive personal characteristics included activity, charisma, and  communicative skills. However, the personal qualities of the  "American" clearly expressed some negative traits, e.g. hypocrisy  and lies. The generalized  image of "the typical American" is  outwardly pleasant, active, and sociable but internally hypocritical,  deceitful and selfserving. The content of the heterostereotype  reflected a certain distrust of young people to "the typical American". The negative characteristics of the heterostereotype may reduce  tolerance of young people to the USA and its representatives. The  results of the study may be useful to representatives of public  authorities and educational institutions. The obtained data can be  used to shape multicultural educational environment in Russian  universities.

Authors: Proskuryakova L. A.
Published: May 2019

The research examined eating disorders and the risk of their development in students according to the level of personal anxiety  from a gender perspective. An analysis showed a connection  between the level of personal anxiety and compulsive and external  types of eating behavior in female students. The sample group  consisted of 70 people, of whom 52,9 % had a high level of personal anxiety (the proportion of girls was 83,8 %). 95,7 % of students had either compulsive (64,2 %) or external (21,4 %) eating disorder. At  this age, an eating disorder does not affect body weight. However, if  the level of personal anxiety increases, it escalates the risk of  developing at least three types of eating disorders by 11,5 times. With an increase in the level of personal anxiety, the risk of  developing external overeating increases by 12,5 times and the risk  of developing a compulsive type of eating behavior increases by 1,5  times. The research revealed some gender features of eating  disorders development: girls with a high level of personal anxiety  proved to have a 5,68 times higher risk of developing various eating  disorders. However, a study in the ability to cope with stress in  students with different levels of personal anxiety with regard to  gender did not show any statistically significant differences in the  study groups. The research demonstrated that there is a need in  psycho-preventive measures that would shape rational nutrition  stereotypes in students.

Authors: Loginova I. O. , Sevost’yanova M. S.
Published: May 2019

The article continues a series of studies devoted to the actual problem of increasing sports effectiveness and the growth of  professional longevity of highly qualified athletes – members of  Russian national sports teams. Not contradicting the methodological  foundations of research of sports activities, the authors propose a  solution to the problem of psychological and pedagogical support of  professional success in sports of higher achievements. The research  is based on the systemic anthropological psychology and the theory  of human self-realization. The subject of this study is the  peculiarities of the stability of the lifeworld in athletes with various  levels of professional success. The paper features a comparative  analysis, the results of which clearly illustrate the specific features of the manifestation of the lifeworld stability in athletes with various levels of professional success. It was empirically proved that  the high degree of life-world stability and the constructive nature of  its manifestation are the psychological conditions for the optimal  combination of processes of achieving high athletic results and  maintaining a high level of mental adaptation. It determines the  sustainability of the lifeworld as a systemic psychological  characteristic responsible for the effective professionalization in the  sport of higher achievements. This allows the authors to conclude  that the program of psychological and pedagogical support  introduced in this paper will probably improve sports effectiveness  and mental adaptation of athletes, contributing to the growth of their professional longevity.

Background & Aims:

Chronic liver disease is characterized by complex hemostatic disorders
because the liver is the site where most of the coagulation factors and their inhibitors are synthesized.
The aim of this study was the evaluation of protein C and antithrombin III in different stages of
chronic hepatitis B and C and to determine their possible role as markers of liver cell damage in different
clinical stages.

Methods:

The study included 60 subjects who were subdivided into 4 groups: (Group I): 15 patients
diagnosed as chronic viral hepatitis B or C, (Group II): 15 patients with compensated liver cirrhosis,
(Group III): 15 patients with decompensated liver cirrhosis, and (Group IV) (control group): 15 healthy
individuals. History taking, clinical examination and abdominal ultrasonography were made for all
subjects. Investigations were done in the form of liver function tests (ALT, AST, ALP, serum bilirubin,
and serum albumin), PT, PTT, CBC. Plasma levels of Antithrombin III & protein C were estimated by
automated Stago compact coagulation analyzer.

Results:

In all patient groups, the mean value of Protein C showed significant decrease when compared
to control group, mean value of antithrombin III showed a significant decrease in compensated and
decompensated subjects when compared to chronic hepatitis and control groups. Antithrombin III and
protein C showed a significant negative correlation with (ALT, AST, PT, PTT, INR). However, this
correlation was positive with Albumin.

Conclusion:

Antithrombin III and protein C are natural anticoagulants and can be considered as markers
of different stages of chronic liver disease. This is supported further by the comparison between the
levels of these parameters and clinical stages of liver disease. Protein C is more sensitive than ATIII as
a marker of hepatocellular damage.
Imbalance of Steroid Hormones in Hamsters Infected with Schistosoma mansoni
Authors: Oliveira Katia C. , Cardoso Rita , Dos Santos Antonio C. , Fernandes Ruben , Botelho Monica C.
Published: May 2019

Objective:

Schistosomiasis is a debilitating disease that affects 200 million people worldwide.
Schistosoma haematobium and Schistosoma mansoni are the major causative agents of this disease.
Cancer-association and infertility-association in Schistosoma haematobium infection have already
been described and it is known that the parasite produces a catechol-estrogen molecule that induces
a hormonal imbalance in the host.

Methods:

In order to better understand the relation of hormonal imbalance in experimental Schistosoma
mansoni infection, we investigated a serum panel of steroid hormones in Schistosoma mansoni
infected hamsters.

Results:

We found a decrease in the serum levels of Estradiol (E2), Testosterone and Progesterone in
infected females and an increase of Testosterone and a decrease in Progesterone in infected males in
comparison with controls.

Conclusion:

These results indicate that S. mansoni alters the levels of steroid hormones in infected
males and females and it will increase the repertoire of data about the host-parasite molecular interplay
and its relation with the endocrine system.
Features of designing IoT systems
Authors: Anufrienko A. Yu.
Published: May 2019

The development of IoT systems, especially in the field of Industrial Internet of things with a large number of end devices is a complex scientific and technical problem. Inability to take into account the number of factors at the early stage leads to a negative result. This document demonstrates the scientific approach to the creation of the above systems. The IoT protocols, the IoT system architecture and its components are described in this article. The problems arising in the design of IoT systems are described. The basic characteristics of the most common protocols are systematized. The method for solution of the actual scientific and applied problem, allowing to design the IoT system, taking into account various fundamental parameters including the frequency range, bandwidth, data transfer rate, radiated power, range, work intensity, as well as the fundamental constraints, is proposed. As a result of the application of the described method, the optimal IoT protocol can be chosen to build a system, or to determine and optimize the parameters of the proprietary protocol. That makes it possible to build a reliable and scalable IoT system for the solution of the relevant experimental problems.

Authors: Krylov V. P. , Bogachev A. M. , Pronin T. Yu.
Published: May 2019

This article deals with the possibilities of methods of the deep-level transient spectroscopy in semiconductors and the reasons constraining their application for industrial control of potential defects of the semiconductor electronic component base. Among the reasons there are an ambiguous interpretation of the results of indirect measurements, the lack of the domestic regulatory base and software and hardware tools, a variety of algorithms and techniques of measurements and processing of results. Models of hardware transformations of weak relaxation responses of microelectronic barrier structures are proposed. The methodology and results of experimental studies of the characteristics of potential defects of serial semiconductor diodes by the method of frequency-temperature scanning using the developed models are described. The obtained results indicate the possibility of a significant increase in accuracy of measurements of parameters of potential defects. The conclusion is made about the need to organize and perform interlaboratory checking on uniform samples to promote the methods of the deep-level transient spectroscopy in the practice of industrial monitoring.
Evaluation of open-loop linear drive accuracy achieved by calibration and linear thermal expansion compensation
Authors: Slobodzyan N. S.
Published: May 2019

The study is a part of the current work on the design and creation of a precision mechanism with parallel kinematics such as a space hexapod. The positioning accuracy and repeatability of the movable platform of the machine relative to its fixed base in the structure under consideration depends on the accuracy of the actuating elements of the hexapod – linear drives. The aim of the work is to assess the achievable accuracy of the linear drive, taking into account the main factors affecting the accuracy of its rod movement. The article describes the studies of the accuracy of the open-loop linear drive, which has no common feedback on the output coordinate. The main factors affecting the accuracy of movement are highlighted. The experimentally obtained estimates of the linear drive rod displacement errors are given. A technique is proposed for improving the linear drive accuracy by programmatically calibrating its ball screw drive and compensating for linear thermal expansion (LTE) when the drive is operating in a wide temperature range. An estimate of the calibrated linear drive rod movement accuracy with LTE compensation has been obtained.
Design and evaluation of a large, wide-scope autostereoscopic laser display for outdoor use
Authors: Karimov K. N. , Lipatov Yu. V. , Khaybullin R. K.
Published: May 2019

Modern autostereoscopic displays often do not meet the mandatory requirements for external use due to limitations in size, brightness, the number of 3D viewing zones, etc. The design concept for modular autostereoscopic laser displays with a wide viewing angle and a vivid luminosity, the theoretical viewing area of the 3D image reaches several thousand observers at a distance of up to 70 m is proposed herein. Each element of the image contains three laser diodes and cylindrical microlenses. To demonstrate the proposed solution, a prototype of a display on a 5×3 trixel board was developed and the optical properties of the prototype were characterized. The concept makes it possible to create a modular display without restrictions on the overall size, which is able to send information about the image to the left and right eyes of several viewers, proving the effectiveness of the proposed approach. Such displays can be used at large exhibitions, venues for air shows, walls of high-rise apartment buildings located along the highways, to attract consumers.

Authors: Bortolanza Ana Maria Esteves , Freire Renata Teixeira Junqueira
Published: May 2019

Este artigo analisa gestos da escrita de uma criança de seis anos que frequenta o primeiro ano do Ensino Fundamental, período inicial de sua alfabetização, em 2015. Os dados coletados em uma entrevista informal fazem parte de um projeto de pesquisa institucional em andamento denominado A formação da atitude autora e leitora no processo de apropriação da escrita na educação infantil, que se estendeu aos primeiros anos do ensino fundamental, tendo como objetivo compreender como as crianças se apropriam da escrita em contextos educativos formais e informais. Trata-se de uma pesquisa qualitativa, de caráter etnográfico, realizada por meio de observações, entrevistas e experimentos pedagógicos. Neste artigo analisamos os resultados de uma entrevista com Ivo, uma criança de seis anos cujos registros escritos analisados evidenciam o paradoxo entre significar a escrita na vida e decifrar o código alfabético na escola. Conclui-se que, embora a escola alfabetize priorizando o ensino do código alfabético, portanto o aspecto externo da escrita, a criança busca apropriar-se de sua significação social, atribuindo-lhe sentidos que são construídos no entorno da família e de outros contextos.
