Published: June 2019

En este trabajo se presenta el diseño e implementación de un prototipo de máquina trituradora de plástico PET (Tereftalato de polietileno), como una alternativa de solución tecnológica al gran problema de la contaminación ambiental por el excesivo consumo de materiales poco degradables como es el plástico.

Este proyecto se enmarca en una solución de innovación tecnológica local dado que en la región La Libertad-Perú a pesar del alto consumo de materiales plásticos no existe una estrategia formal de reciclaje o eliminación de este tipo de desechos ni tampoco desarrollos tecnológicos para ese fin. Por lo que la propuesta que se implementa en este trabajo tiene un aporte de innovación tecnológica para el reciclaje de plásticos y así contribuir en la transformación o eliminación de residuos plásticos.

Por otro lado, los plásticos tipo PET son fácilmente triturables a dimensiones minúsculas para posteriormente ser utilizados en diferentes procesos que determinan productos útiles al hombre o con menos efectos negativos al medio ambiente. Y en ese sentido, el trabajo presentado aquí desarrolla un prototipo de máquina trituradora cuyas partes y componentes son de fácil construcción o adquiribles en el entorno local.

La máquina trituradora de Plástico desarrollado aquí se compone de 3 partes fundamentales: (1) Sistema eléctrico con lógica de mando y arranque directo de un motor trifásico. (2) estructura mecánica o cuerpo del equipo, que permite sostener o soportar a las diferentes partes de la máquina. (3) sistema de trituración, que convierte el plástico reciclado en pequeñas virutas, las que son luego almacenadas en un deposito que es parte de la maquina desarrollada.

Los conocimientos adquiridos en el curso de electromagnetismo, de la carrera Ing. Mecánica-eléctrica permiten realizar el diseño y construcción de una máquina trituradora de residuos plásticos que garantice su funcionamiento adecuado, facilidad de operación, seguridad laboral y una adecuada selección de los diferentes elementos y materiales requeridos para la implementación del equipo.

Three Journeys: One Project
Authors: McGee-Lockhart Olivia , Tandy Kisha , Copeland Andrea
Published: June 2019

The Bethel Project is about the history of Indianapolis’ oldest black church, archival records, preservation technologies, virtual experiences, and collaboration and co-creation among many different departments, heritage institutions and community members. This paper provides three perspectives on this project from individuals who’ve worked closely together over the past four years. This may seem like a long while to work on one project but for those whose research is community-based it seems about right. Three unique voices will be presented with each telling their own narrative of what she thought when the project started and how her thinking has changed until now. Andrea Copeland is an associate professor in the School of Informatics and Computing whose research focuses specifically on public libraries, community collections, and engagement. Kisha Tandy is the associate curator of social history at the Indiana State Museum who researches African American history and culture. At the center of the project is Olivia McGee Lockhart: Bethel AME Church of Indianapolis’ Keeper of History, Indianapolis native, and an Indianapolis Public Schools educator for nearly four decades.
Trust in Participatory Action Community Engaged Partnerships: Relationships and Historic Trauma Matter
Authors: Pierce Barbara , Klemme Paige , Tate Val , Studley Mary
Published: June 2019

University-community participatory action partnerships can be mutually beneficial. Universities often work alongside communities to establish new and innovative community-based programming and research that are intended to benefit communities from these efforts. However, mistrust has been found to be a major issue in creating and maintaining strong relationships. This paper will marry a model of trust that forms when partners exhibit relational capital, relational embeddedness, and transparency within the principles of trauma-informed care as established by the Substance Abuse Mental Health Services Administration (SAMHSA) (2014).
A group of university researchers and community activists/organizers analyzed their work on a project to bring a community engaged participatory action design team intervention to develop and implement trauma-responsive care in an established transitional African American community located in a large urban Midwestern city. Through our analysis we identified three major reasons for mistrust:  objectification of community members, lack of real change in the community, and lack of transparency.. Additionally, we found that paying attention to power differentials between the university researchers and community partners is key. Major findings around best practices mirrored the SAMHSA trauma-informed care principles and included developing “not just trust but trusting relationships”, sharing “voice and choice” with all who seek to participate, understanding the historical trauma within the community, using cultural guides and long time seasoned community organizers to facilitate processes, “showing up” and being interested in the community beyond the research or intervention by finding a way to give back to the community beyond the project.
Artful Spaces/Safe Places: A Gallery Provokes Voices that Interrogate Common Narratives of Latino Immigrant Children
Authors: Borgmann Cindy Bixler , Peñalva Stacy
Published: June 2019

What do Latino immigrant children’s voices say as they are provided a safe community space to be heard and soft clay through which to speak? Through art work, focus groups, gallery exhibitions, and filtering data (Author, 2018)  this critical ethnographic research (Madison, 2012; Merriam & Tissdell, 2016; Wolcott, 2008; Thomas, 1993)  exposes the complex political nature of linguistic, cultural, and national negotiations in which Latino children and their families in this study engage daily.  This work troubles stereotypic mainstream narratives (Dillard, 2012; hooks, 1990, 1994; Janks, 2010) and points out the need for strong community/university collaborations to impact the excavation of deeper understandings of people in our neighborhoods. This ethnographic portrait of families, part of a larger study, involved the community director in an urban Spanish speaking church and faculty from literacy education and visual art at IUPUI.  In this study children created clay objects called “hanging journals” during a summer program.  These clay artworks acted as semiotic mediators (Kress, 2010; Pahl & Rowsell, 2012) for voices of this group—voices which routinely go unheard, or are devalued. Using theoretical frameworks from the fields of literacy and art, layered with multiplex ethnographic research tools, the volume on these important and complicated voices was turned up to hear buried stories and to interrogate commonly accepted narratives that swirl around Latino immigrants and their families.
            This study provides a peek into the authentic narratives of children as they share the daily navigation of a transnational existence, and shows the power of the arts to communicate across contested spaces. This study embraces the necessity of authentic university/community collaborations as a two-way street to understand and empower Latino youth, to better prepare future teachers as agents of change, and to expose versions of immigrant ways of being and knowing that are misconstrued.
Analysis of Modular DCM Flyback Converters in Input Parallel Connections with Parametric Mismatches
Authors: Fuerback Vinícius B. , Dall’Asta Matheus S. , Pagliosa Mauro André , Lazzarin Telles B.
Published: June 2019

This paper analyzes the effects of parameter mismatches in the balance mechanism of modular DC-DC Flyback converters operating in discontinuous conduction mode. The natural current and voltage distributions among modules are evaluated when mismatches on duty cycles, transformer magnetizing inductances and transform turns ratios are present. From these results, the critical values of inductances and duty cycles that assure the discontinuous operation are equated. The small-signal equivalent circuit for Input-Parallel-Output-Series and Input-Parallel-Output-Parallel connections are found, followed by a simple control strategy. The theoretical analysis is verified by experimental results obtained with a prototype composed of three 200 W Flyback modules, with a rated power of 600 W and maximum efficiency of 95.5%. Results corroborate the proposed equations for the steady state balance and dynamic behavior of both connections, highlighting the modular characteristic of the converter.
The role of hemodynamic limitations in the reduction of exercise capacity in patients with sarcoidosis
Authors: Gudim A. L. , Postnikova L. B. , Boldina M. V. , Bychkova E. V.
Published: June 2019

Aim: To perform comprehensive evaluation of the Cardiopulmonary Exercise Testing (CPET) parameters with gas analysis in patients with pulmonary sarcoidosis (PS) and to assess the effects of hemodynamic limitations on the reduction of exercise capacity (EC).

Materials and methods: We examined 42 PS patients (25 men, 17 women) aged from 22 to 62 years (34.5 [29; 41.5] years old). PS had been verified histologically in 33 (78.6%) patients. The group 1 included patients with decreased oxygen consumption per minute at the peak load (n = 20) with VO₂ peak pred ≤ 84%, i.e. with decreased EC. Group 2 consisted of 22 patients with normal VO₂ peak pred (> 84%). In all patients, echocardiographic and CPET parameters were assessed that characterize response of the cardiovascular system to physical exercise, such as oxygen consumption at the anaerobic threshold (VO₂ AT, % of predicted value); oxygen pulse (VO₂/HR, abs/% of predicted), the chronotropic-metabolic index (CMI), and blood pressure.

Results: Thickening of the left ventricular posterior wall (p = 0.012) was found in the group 1, together with decreased VO₂ AT (р < 0.001), VО₂/HR (р < 0.001), and systolic blood pressure (p = 0.037) at the peak load during CPET, compared to the parameters in the group 2. Twelve patients from the group 1 demonstrated their VO₂ AT < 43%, 6 patients had decreased VО₂/HR < 80% of predicted, and 3 patients were diagnosed with the chronotropic incompetence phenomenon.

Conclusion: Decreased EC was identified by CPET in 47.6% of PS patients without any functional abnormalities at rest. The reduction of EC in 17/20 PS patients from the group 1 was associated with abnormalities in CPET parameters, corresponding to the hemodynamic limitations (reduction of cardiac output and chronotropic incompetence).

Authors: Mikasi Masiza Samuel , Baloyi Joseph Jimu , Bhebe Everson
Published: June 2019

This experiment was conducted to evaluate the effects of supplementing 10% or 15% of baobab seed cake (BSC) or macadamia oil cake (MOC) in fattening diets for lambs on feed intake, growth performance and carcass characteristics. Thirty-two lambs aged between 150 and 180 days were randomly allocated to 4 diets (10% MOC; 15% MOC; 10% BSC and 15% BSC diets) in an experiment arranged as a 2x2 factorial design and sex as a block. The results showed that there were significant protein source and inclusion level interactions on average daily feed intake, average daily gain, and total weight gain, warm and cold carcass mass. Males were significantly superior in all parameters except for feed conversion ratio, dressing percentage and rib-eye area. It was concluded that 10% MOC and 15% BSC can be incorporated in diets for fattening of growing South African Mutton Merino lambs without compromising on their growth performance and carcass characteristics.

Published: June 2019

This study was conducted to identify the diversity of chicken growth hormone (cGH) single nucleotide polymorphs’ (SNP) and their association on morphometric and growth traits of three Nigerian chicken breeds namely Funaab Alpha (FA), Shikabrown (SB) and Nigerian local chicken (NLC). Morphometric traits measured include shank length (cm), breast girth (cm) and breast width (cm) while growth traits measured were final body weight, av. weight gain, feed intake and feed conversion ratio all at laying stages respectively. Morphometric and growth traits were significantly influenced (P less than 0.05) between the different breeds. The SNP panel showed two base pair substitution mutation (GT and CA) on locus 5 chromosome for the FA and locus 6 chromosome for the SB and NLC respectively. The G – T alignment produced genotypes GG and GT, with TT not observed. Also C – A alignment produced genotypes CC and CA, with AA not observed. The NLC breed had the highest number of haplotypes of 6 while FA and SB had 4 haplotypes each implying that the local breed had more allelic variation than the other two breeds. Also FA had heterozygosity of 0.48 while SB and NLC had a value of 0.44, indicating higher genetic variability of FA breed than the rest with negative theta value (-0.0843) of F-statistics indicating high level of outbreeding. The conducted association of SNP genotypes showed no significant association effects (P>0.05) on the morphometric traits, except for SB breed where CA genotypes was significantly associated with CC for bodyweight, and in NLC breed where CC genotype was also significantly associated with CA genotypes for shank length.

Published: June 2019

Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most commonly used class of drugs for treating inflammation and pain. Meloxicam has analgesic, anti-inflammatory and antipyretic properties and is a commonly used NSAID in veterinary practice. The present study was done to evaluate effect of meloxicam on toxico-pathological and hematological parameters in Wistar rats. Eighteen Wistar rats were equally divided into three groups i.e. Group I, Group II and Group III. Group I (negative control) rats received only Normal saline (0.9%) @ 1ml/kg. Group II (Low dose) received meloxicam@ 4 mg/kg B.W. and Group III (High dose) rats received meloxicam@8 mg/kg B.W. orally by gavage for 28 days. Dose-dependent clinical signs and lesions were observed after meloxicam treatment. Kidneys and liver were severely hemorrhagic at the high dose, while intestine and stomach had ulcers and erosions. Hematological values were altered after 28 days of administration. Total Erythrocyte Count (TEC), Packed Cell Volume (PCV), Haemoglobin values were decreased and TLC count was significantly increased in both doses of meloxicam treated groups in a dose-dependent manner. It was concluded that meloxicam caused GIT lesions, nephrotoxicity, hepatotoxicity and variation in the hematological parameters at selected dose and duration.

Published: June 2019

A two year field experiment was conducted in hot arid region at Bikaner, Rajasthan to investigate the effects of application of sulphydryl compounds (thioglycollic acid, TGA; thiourea TU) on growth traits, photosynthetic efficiency, yield components and yield of moth bean under water deficit conditions. The experiment comprised seven treatments (water spray, TGA 200 mg L-1, TGA 300 mg L-1, TGA 400 mg L-1, TU 500 mg L-1, TU 750 mg L-1 and TU 1000 mg L-1) and laid out in randomized block design with three replications. Application of sulphydryl compounds had significant effects on growth, photosynthetic traits, activities of anti-oxidant enzymes, and yield of moth bean. The sulphydryl compounds sprayed plants had 24-70, 13-40 and 13-20 % higher activities of antioxidant enzymes (glutathione reductase, GR; gluthathione-s-transferase, GST), photosynthetic parameters (net photosynthetic rate, PN; stomatal conductance, gs; transpiration rate, E) and seed yield respectively compared to unsprayed plants. The results suggest that application of sulphydryl compounds mitigate moisture deficit induced negative effects on growth, and photosynthetic parameters which lead to better seed yield of moth bean.

Seed germination and seedling growth are the most sensitive plant stages towards salinity. Various techniques can improve emergence and stand formation under salt conditions. Seeds priming is one of the most frequently used technique. Seed priming could develop different defence mechanisms of seeds against salinity stress. This experiment aims to examine the seed priming into potassium nitrate - KNO3 (1%), ascorbic acid – ASA (100mgl-1), and potassium chloride - KCl (1%) solutions, that may reduce harmful effects of salinity stress. Salinity was imposed by treatment of seeds with different concentrations of NaCl (0 (control), 50, 100, 200m MNaCl). All data were analysed statistically by three-way ANOVA. Individual testing of probability was carried out using Tukey’s method p £ 0.05 and p £ 0.01. Correlation dependence was determined using the Pearson correlation coefficient. Test results demonstrated positive effect of seed priming. This was showed by improved soybean seed quality and increased seed germination rate. The intensity of lipid peroxidation, free proline concentration and Na+ was decreased, while K+ in seedlings increased due to priming treatment. Priming of seeds into ASA solution resulted in increased vitamin C concentration, while priming into KNO3 and ÊCl solutions reduced the content of vitamin Ñ in soybean seedlings.
Stratied Finite Empirical Bernstein Sampling
Authors: Burgess Mark Alexander , Chapman Archie C.
Published: June 2019

We derive a concentration inequality for the uncertainty in the mean computed by stratified random sampling, and provide an online sampling method based on this inequality.  Our concentration inequality is versatile and considers a range of factors including: the data ranges, weights, sizes of the strata, the number of samples taken, the estimated sample variances, and whether strata are sampled with or without replacement.  Sequentially choosing samples to minimize this inequality leads to a online method for choosing samples from a stratified population.  We evaluate and compare the effectiveness of our method against others for synthetic data sets, and also in approximating the Shapley value of cooperative games.  Results show that our method is competitive with the performance of Neyman sampling with perfect variance information, even without having prior information on strata variances.We also provide a multidimensional extension of our inequality and discuss future applications.

Accounting for Spacers in the Mechanical Calculation of Flexible Wires for Overhead Lines and Switchgears
Authors: Bladyko Yu. V.
Published: June 2019

The mechanical calculation of flexible wires of overhead lines and switchgears, in which in-phase or phase-to-phase spacers are installed, is under consideration. Spacers are considered as concentrated loads acting on the split phase. The formulas for determining the sag are given for a different number of spacers as a function of their number and the coefficient of concentrated forces. This takes into account the difference in suspension heights, tension insulators strings, wind and ice loads. These formulas, being presented in a form that is convenient for consumers, can be used for computer execution of the mechanical calculation of flexible wires in different climatic regimes, both in the presence and in the absence of phase splitting. The errors of replacing the spacers with a distributed load are demonstrated. Formulas are proposed that give the smallest error when replacing spacers with a distributed load. The greater the value of the concentrated forces from the tap-off lines and loops, the greater the error in calculating the sag of the switchgears wires. Therefore, it is not possible to replace them with a distributed load obtained by simply dividing the total load by the length of the span in the presence of the tap-off lines and loops.
Thermal and Aerodynamic Researches of Staggered Bundles for Choice of an Effective Spacing of Round-Finned Tubes
Authors: Kuntysh V. B. , Sukhotskii A. B. , Marshalova G. S. , Dudarev V. V. , Farafontov V. N.
Published: June 2019

The results of an experimental study of local modeling of convective heat transfer and aerodynamic resistance of staggered six-row bundles of bimetallic tubes with spiral knurled aluminum fins under transverse air flow in the range of its velocity alteration in a compressed bundle section of 1.9−11.0 m/s are presented. The velocity range covers the possible modes of operation of industrial air coolers (AVO). The fins with a diameter of approximately 57 mm are rolled on a steel supporting tube with an outer diameter of 25 mm. Tube finning ratio j = 19.26. Such tubes are widely used in the heat exchange sections of AVO of natural gas, in particular, at “Gribanovskii Engineering Plant” JSC (Russia). To measure the reduced heat transfer coefficients, an electric calorimeter had been developed by the authors with a power input of 600−1300 W. The temperature of the wall surface at the base of the fins did not exceed the range of 77–92 °C. The transverse tube spacing in bundles S1was 64.0 or 68.0 mm, while the longitudinal spacing S2 was 54.4 or 50.0 mm. The heat transfer of each transverse row of six-row bundles was measured, as well as the average heat transfer and aerodynamic drag, which are summarized by the similarity equation of a power type. The heat transfer rate of the last transverse row in the direction of air movement is 0–5 % lower than the heat transfer rate of the stabilized rows, and here new features of heat transfer variations in the insufficiently studied area of spacing changes S1 and S2 have been found. The thermal contact resistance (TCR) was measured in the range of the average temperature of the contact surfaces tк = (79–95) оС, and no dependence of the value of TCR on tк for the specified interval was found. The numerical average value of TCR was Rк = 2,13 × 10–4 m2×K/W, which is typical for reliable mechanical connection of the finned aluminum shell with the supporting steel tube made of carbon steel. The results of variant thermal and aerodynamic calculations with the use of the obtained data established the technical and economic feasibility of placing tubes at the vertices of an isosceles triangle with spacing S1 = 68–69 mm and S2 = 55 mm with failure to use the location of the tubes along an equilateral triangle with S1 = S2' = 64 mm (where S2' – is diagonal spacing). With Q = idem and other conditions being equal, the number of tubes on AVO decreases by 5.7 % with a decrease in power consumption to 4.0 %.

Published: June 2019

In the article the technique of an assessment of modes of operation of the heat engineering equipment used for heat treatment of concrete products in the conditions of programcontrolled heat supply according to the pattern of “heating – isothermal influence – cooling” has been developed. The method is based on the numerical solution of a non-stationary heat equation supplemented by equations describing the hydration process of a concrete product; also, it includes a system of initial and boundary conditions for its spatial structure. The method makes it possible to create tabulated functions of temperature and the degree of hydration of the time of heat treatment in any point of a 3D-product. The mathematical tools for calculating the functional dependencies of concrete hydration equipment with software-heated environment are presented. Numerical calculations of the concrete hydration process in the formwork are performed with respect to the symmetrical object. Based on the calculation of the temperature gradient across the minimal cross section of the product, a numerical analysis of the functions modeling heat supply mode depending on the processing time of a concrete product has been fulfilled. It is demonstrated that the maximum speed of the hydration process in a concrete product hardening is achieved at the maximum of time lag of isothermal cure. Additionally, with an increase in the duration of the product heating, the value of the maximum hydration rate decreases. It is concluded that the method of assessing the mode of heat treatment of concrete products being developed makes it possible to determine parameters for the calculation of the minimal useful heat required for the heat treatment of concrete products with spatially distributed parameters. The proposed method is applicable to calculate the temperature fields and the extent of hydration in the products of any geometric shape and volume in a software-controlled heating environment of industrial facilities for the accelerated hydration of concrete, and also affords the possibility of preliminary calibration prior to the assignment of relevant heat supply modes to the products being processed.

Published: June 2019

Background: Assessing body image among breast cancer survivors is essential to the development of good treatment and rehabilitation plans. Culturally-appropriate methods and instruments are needed for body image assessment. The aim of this study was to assess the psychometric properties of the Persian version of Body Image after Breast Cancer Questionnaire.
Methods: In this methodological study, the Body Image after Breast Cancer Questionnaire was translated into Persian through forward-backward translation. Then, its content validity was assessed by twelve experts, and 400 women with breast cancer completed the questionnaire. The construct validity of the questionnaire was evaluated through exploratory and confirmatory factor analyses and its convergent and discriminant validity were evaluated using Fornell and Larcker’s approach. The reliability of the questionnaire was also evaluated through Cronbach’s alpha, McDonald’s omega, and composite reliability.
Results: In exploratory factor analysis, five factors were extracted, namely vulnerability, body stigma, body-related shame, body satisfaction, and physical disability stigma. Confirmatory factor analysis also confirmed the fit of the five-factor model (χ2 = 466.95; N = 241; P < 0.001; PCFI = 0.728; PNFI = 0.624; CMIN/DF = 1.938; RMSEA = 0.068; AGFI = 0.808; IFI = 0.838). Second-order factor analysis also revealed that the subscales of the questionnaire measured an overarching concept which was labeled “Body image stigma”. The questionnaire had acceptable content and convergent validity and composite reliability.
Conclusion: The Persian version of Body Image after Breast Cancer Questionnaire measures the broad concept of “Body image stigma”. The Persian BIBCQ has acceptable validity and reliability and hence, can be used for assessing body image among breast cancer survivors.

Transcriptome sequencing of a keystone aquatic herbivore yields insights on the temperature-dependent metabolism of essential lipids
Authors: Windisch Heidrun Sigrid , Fink Patrick
Published: June 2019

Background:
Phytoplankton dietary quality is the major determinant of the trophic transfer efficiency at the plant-herbivore interface in freshwater food webs. In particular, the phytoplankton’s content of the essential polyunsaturated omega-3 fatty acid eicosapentaenoic acid (EPA) has repeatedly been shown to determine the secondary production in the major zooplankton herbivore genus Daphnia. Despite extensive research efforts on the biological model organism Daphnia and the availability of several Daphnia genomes, little is known on the molecular mechanisms underlying the limitation of Daphnia by dietary EPA availability.
Results:
Here, we used RNAseq to analyse the transcriptomic response of Daphnia magna fed with diets with or without EPA to specifically analyse gene-networks and pathways that are driven by dietary EPA availability. Since EPA is – among other functions – critical to the adaptation of poikilothermic organisms to low environmental temperatures, we ran our experiment at two temperature levels to investigate potentially constrained physiological responses to EPA availability at lower temperatures. Here, trade-offs between food quality and homeoviscous adjustments of biological membranes are expected through the incorporation of polyunsaturated fatty acids.
Conclusions:
Our highly controlled eco-physiological experiments revealed an orchestrated response of genes involved in transformation and signalling of the essential fatty acid, including eicosanoid-signalling pathways with potential immune functions. We provide an overview of downstream-regulated genes, which contribute to enhance growth and reproductive output. We also identified numerous EPA-responsive candidate genes of yet unknown function, which constitute new targets for future studies on the molecular basis of EPA-dependent effects at the freshwater plant-herbivore interface.

Background: Ventriculoperitoneal shunting (VPS) is a common neurosurgical procedure for treating hydrocephalus. Catheter obstruction is one of the most common factors influencing patient prognosis. We evaluated the possibility of improving the accuracy of proximal catheter placement and the probable relationship of ventricular catheter obstruction with the symptom grade and postoperative Evans index with intraoperative navigation for VPS compared with conventional surgery via the occipital horn.
Method: We performed a retrospective study including 33 patients with VPS in the navigation surgery group and 26 patients with VPS in the conventional surgery group between January 2012 and August 2018. The clinical data, follow-up time, catheterization accuracy, postoperative outcomes, cumulative survival time and correlations of catheter placement with obstruction and of catheter obstruction with the symptom grade and postoperative Evans index were analyzed.
Results: Thirty-one patients experienced optimal ventricular catheter placement (grade 1), 2 patients experienced suboptimal placement (grade 2), and no patients experienced poor ventricular catheter placement (grade 3) in the navigation surgery group compared with 6, 14, and 6 patients, respectively, in the conventional surgery group. Greater improvement in postoperative symptoms (P=0.017) was observed in the navigation surgery group, including less catheter readjustment (P<0.001). Kaplan-Meier survival analysis showed that the cumulative catheter obstruction-free survival time was longer in the navigation surgery group than in the conventional surgery group (P=0.028). Catheter placement was significantly correlated with catheter obstruction (P<0.001). In addition, catheter obstruction was significantly correlated with the symptom grade (P=0.001) and postoperative Evans index (P<0.001).
Conclusions: The intraoperative navigation system for VPS improved patient outcomes and the accuracy of ventricular catheter placement. Catheter obstruction-free survival time was longer in the navigation surgery group, and catheter placement was significantly correlated with catheter obstruction.

Background: Streptococcus mitis (S. mitis) belongs to the viridans group streptococci, which is rarely isolated as a causative pathogen of corneal ulcers. When S. mitis causes keratitis, penetrating keratoplasty (PK) might be necessary. Herein, we demonstrated that amniotic membrane transplantation (AMT) may be an easier procedure with acceptable outcomes and with fewer complications.

Case presentation: A 63-year-old female presented with a right persistent corneal ulcer that she had suffered from for the past nine months. The culture of a corneal scraping yielded S. mitis. The right eye descemetocele decreased from 3 mm in diameter to 0.8 mm in diameter after the continuous administration of topical vancomycin and ceftriaxone for two weeks. Due to the slow healing, AMT was performed. Her corneal erosion healed and gradually became clear. Her visual acuity recovered from initially counting fingers to 20/200 17 months after AMT.

Conclusion: This unusual case illustrated that antibiotics plus AMT may be an effective alternative treatment instead of PK to promote epithelialization and to reduce inflammation in corneas complicated by S. mitis keratitis.

Background

Some Gynura species were reported to be natural anti-diabetic plants. The chloroplast genomes of four Gynura species were sequenced for hybridizations to improve agronomic traits. There are only 4 genera of tribe Senecioneae have published chloroplast genome in Genbank up to now. The internal relationships of the genus Gynura and the relationship of the genus Gynura with other genera in tribe Senecioneae need further researches.

Results

The chloroplast genome of 4 Gynura species were sequenced, assembled and annotated. Comparing with other 12 Senecioneae species, the chloroplast genome features were detailedly analyzed. Subsequently, the differences of the microsatellites and repeats type in the tribe were found. By comparison, the IR expansion and contraction is conserved in the genera Gynura, Dendrosenecio and Ligularia. The region from 25,000 to 50,000 bp is relatively not conservative but the 7 ndh genes in this region are under purifying selection with small change in amino acids. The phylogenetic tree shows two major clades, same as the sequence divergence in region 25,000 to 50,000 bp. Based on the oldest Artemisia pollen fossil, the divergence time were estimated.

Conclusions

Sequencing of chloroplast genome of the 4 Gynura species help us to develop abundant genetic resources. The phylogenetic relationships and divergence time among 4 Gynura and 16 Senecioneae species were sorted out by comparing the chloroplast genomes. The phylogenetic relationship of the genera Gynura and Ligularia is different with former work and further morphology and genome-wide analysis are needed to clarify the genera relationship.
Why Humans Aren’t Just Great Apes
Authors: Dunbar Robert I.M.
Published: June 2019

Although we share many aspects of our behaviour and bi­ology with our primate cousins, humans are, nonetheless, different in one crucial respect: our capacity to live in the world of the imagination. This is reflected in two core aspects of our behaviour that are in many ways archetypal of what it is to be human: religion and story-telling. I shall show how these remarkable traits seem to have arisen as a natural development of the social brain hypothesis, and the underlying nature of primate sociality and cognition, as hu­man societies have been forced to expand in size during the course of our evolution over the past 5 million years.
The Festival Order – Music Stages of Power and Pleasure
Authors: Lukić Krstanović Miroslava
Published: June 2019

Music festivals consist of a complex of interactions and social and cultural experiences. This paper analyzes mu­sic festivals in SE Europe in their function as a planetary pro­duction, combining regional cross-cultural perspectives and local politics. At the beginning of the 1990s music events in SE Europe (concerts, festivals, cultural happenings) were ei­ther a part of political conflict, antagonisms and economic crises, or they were included in the music world through the cultural contacts of global achievements – the music net and industry. Music festivals become the arena and scene of a contradictory reality in these places, being made up of indi­vidual, group interests, needs, establishment strategy and politics.To illustrate this phenomenon the paper presents the biggest festivals and spectacles in Serbia and SE Europe: EXIT festival (Novi Sad) attracted thousands of techno and rock lovers with the participation of many famous bands; and the folk trumpet playing festival (Guča), which each summer for several decades has been attracting thousands of lovers of ethno sound to a fair-carnival atmosphere. This ethnological research stresses complex property divisions – lifestyle, mu­sic genres, political strategies, scene movements and eco­nomic interests.
The Economic Basis of the Model of Traditional Montenegrin Masculinity
Authors: Banović Branko
Published: June 2019

The model of traditional Montenegrin masculinity is inseparable from the social formations that have contributed to its creation, hence the need for its more thorough economic, social and historical contextualization. It is particularly important to distinguish the two components of the model of traditional Montenegrin masculinity, which tend to be intertwined and are therefore difficult to separate. The first concerns the gender roles assigned to men and women in an economy based on livestock raising, warfare, and raiding, while the other concerns the concept of gender roles shaped by fictional, ethnological and historical narratives. The paper attempts to problematize the economic basis of the model of traditional Montenegrin masculinity in the context of a semi-nomadic livestock raising economy and a clan’s collective property.
The Possibility of Social Change and Pop Music in Serbia: Šobaja’s Three Kisses – A Case Study
Authors: Brkić Aleksandar
Published: June 2019

Can social change be brought about only in a radical manner? Is a radical manner of bringing about change possible at all? When we say social change, do we mean "revolution"? Is there a different way of looking at social change, and what is the role of elite culture and  that of popular culture in these processes? Has the temporally and contextually limited effect of change and guerilla subversion through popular culture proved more effective? This small-scale study aims to raise the question of whether pop music can contribute to positive changes in society, and examines the conditions for this possibility through the case study of Nebojša "Šobaja" Anđelković’s song Three Kisses, declared the biggest music hit of 2009 in Serbia.

Upon nearly twenty years since the beginning of commercialization of the Ukrainian higher education system, the intensity of discussion of its purposes, results and possible amendments did not decrease neither among experts nor among the interested public. Supporters and opponents of commercialization note that education is the social branch, which participates in the formation of prerequisites of economic growth. The main point of the article is to disclose the essence of the phenomena of economism and commercialization. Economism is seen as part of globalization of education, a global corporatization of education provides training for the global labor market, using human capital economic theories. As noted by George Spring, the human capital, economists argue that investments in education lead to economic growth, reducing income inequality and increasing employment.The article confirms that the state educational policy as a component of social policy is one of instruments of influence of the state on formation of social structure and is directed to the solution of problems of societal level. It performs relevant sociological examination of transformational processes in education and, in particular, results of commercialization. Thus, it is possible to claim that the educational system tests the uncommon influence of globalization, forming and building a peculiar system of the relations and interaction.
Subsídio público à oferta educacional privada: reflexões a partir do modelo irlandês
Authors: Adrião Theresa Maria De Freitas , Azevedo Juliana De Paula Eduardo
Published: June 2019

Com base em pesquisa de natureza exploratória, em fontes primárias, secundárias e em entrevistas, o artigo reflete sobre o modelo irlandês de acesso à educação obrigatória, o qual se assenta na escolha de escolas pelas famílias e se organiza sem a presença de escolas estatais, ainda que a oferta educacional seja gratuita. Indica-se, na forma de fechamento não conclusivo, as contradições do modelo decorrentes dos critérios de seleção praticados pelas escolas e dos limites percebidos nas entrevistas aos tipos de escolas “disponíveis” na região de Dublin, elementos que suscitam o aprofundamento de estudos sobre estes formatos, especialmente no contexto de ampliação desse modelo associado a interesses corporativos.
Individuación y mercado educacional en chile
Authors: Orellana C. Víctor , Canales C. Manuel , Bellei C. Cristián , Guajardo M. Fabián
Published: June 2019

Este artículo sistematiza hallazgos de distintas investigaciones sobre la educación chilena para comprender los mercados educativos. A sus reportados déficits de equidad y calidad, se discute su efecto profundizador de la individualización. Prácticas antes emplazadas en el mundo de la vida o en la política ahora son colonizadas mercantilmente, articulando la experiencia de vida como continuo individual de elección de mercado y rendimiento alienado. Se experimenta el mercado educativo como constricción de libertad, lo que se suma a la inequidad y la baja calidad promedio documentada.
