Psychiatry and the geriatric syndromes – creating constructive interfaces
Authors: Thacker Simon , Skelton Mike , Harwood Rowan
Published: January 2018

Integrating mental and physical healthcare is difficult to achieve because of professional and organisational barriers. Psychiatrists recognise the problems resulting from fragmentation of services and want continuity of care for patients, but commissioning and service structures perpetuate these problems. One way forward may be to follow the syndromic model employed by geriatricians as a means of avoiding over-emphasis on diagnosis above the pragmatics of implementing multi-component, coordinated care. Commissioners need to be made aware of the overlap and complementarity of skills possessed by old age psychiatry and geriatric medicine to create joint services for people vulnerable to dementia and delirium. A re-forged alliance between the two specialties will be necessary to turn integrated care for frail, elderly people from rhetoric into reality.
Online media reporting of suicides: Analysis of adherence to existing guidelines
Authors: Utterson Michael , Daoud Jason , Dutta Rina
Published: January 2018

Aims and method

To assess the compliance of contemporary online media output with guidelines for the responsible reporting of suicidal acts. A search engine was used to identify online media reports of suicide from UK sources over the course of 1 month. Each article was assessed against guidelines for the responsible reporting of suicide produced by the Samaritans, a UK mental health charity.

Results

We identified 229 articles, of which 199 failed to comply with at least one of the Samaritans' guidelines. Failure to mention support sources, excessive detail about the method used and undue speculation about the trigger for suicide were the most commonly breached guidelines. Significant differences were found between the quality of local and national media sources, with local media sources being broadly more compliant with guidelines.

Clinical implications

This study highlights the urgent need for the implementation of responsible reporting guidelines in online media articles as a component of suicide prevention efforts.
Biomechanics of swimming in developing larval fish
Authors: Voesenek Cees J. , Muijres Florian T. , van Leeuwen Johan L.
Published: January 2018

Most larvae of bony fish are able to swim almost immediately after hatching. Their locomotory system supports several vital functions: fish larvae make fast manoeuvres to escape from predators, aim accurately during suction feeding and may migrate towards suitable future habitats. Owing to their small size and low swimming speed, larval fish operate in the intermediate hydrodynamic regime, which connects the viscous and inertial flow regimes. They experience relatively strong viscous effects at low swimming speeds, and relatively strong inertial effects at their highest speeds. As the larvae grow and increase swimming speed, a shift occurs towards the inertial flow regime. To compensate for size-related limitations on swimming speed, fish larvae exploit high tail beat frequencies at their highest speeds, made possible by their low body inertia and fast neuromuscular system. The shifts in flow regime and body inertia lead to changing functional demands on the locomotory system during larval growth. To reach the reproductive adult stage, the developing larvae need to adjust to and perform the functions necessary for survival. Just after hatching, many fish larvae rely on yolk and need to develop their feeding systems before the yolk is exhausted. Furthermore, the larvae need to develop and continuously adjust their sensory, neural and muscular systems to catch prey and avoid predation. This Review discusses the hydrodynamics of swimming in the intermediate flow regime, the changing functional demands on the locomotory system of the growing and developing larval fish, and the solutions that have evolved to accommodate these demands.
Claudin-10isoform expression and cation selectivity change with salinity in salt-secreting epithelia ofF. heteroclitus
Authors: Marshall William S. , Breves Jason P. , Doohan Ellen M. , Tipsmark Christian K. , Kelly Scott P. , Robertson George N. , Schulte Patricia M.
Published: January 2018

To provide insight into claudin (Cldn) tight junction (TJ) protein contributions to branchial salt secretion in marine teleost fishes, this study examined cldn-10 TJ protein isoforms of a euryhaline teleost (mummichog; Fundulus heteroclitus) in association with salinity change and measurements of transepithelial cation selectivity. Mummichogs were transferred from fresh water (FW) to seawater (SW, 35 ‰) and from SW to hypersaline SW (2SW, 60 ‰) in a time course with transfer control groups (FW to FW and SW to SW). FW to SW transfer increased mRNA abundance of cldn-10d and -10e by 2-fold, whilst cldn-10c and -10f transcripts were unchanged. Transfer from SW to 2SW did not alter cldn-10d, and transiently altered cldn-10e abundance, but increased cldn-10c and -10f by 4-fold. This was coincident with an increased number of single-stranded junctions (observed by TEM). For both salinity transfers; (1) cldn-10e mRNA was acutely responsive (i.e. after 24 h), (2) other responsive cldn-10 isoforms increased later (3-7 days), and (3) cystic fibrosis transmembrane conductance regulator (cftr) mRNA was elevated in accordance with established changes in transcellular Cl− movement. Changes in mRNA encoding cldn-10c and -10f appeared linked, consistent with the tandem repeat locus in the Fundulus genome, whereas mRNA for tandem cldn-10d and -10e seemed independent of each other. Cation selectivity sequence measured by voltage and conductance responses to artificial SW revealed Eisenman sequence VII: Na+>K+>Rb+∼Cs+>Li+. Collectively, these data support the idea that Cldn-10 TJ proteins create and maintain cation-selective pore junctions in salt-secreting tissues of teleost fishes.
Η εφαρμογή του μετασχηματιστικού μοντέλου ηγεσίας στο σύγχρονο σχολικό περιβάλλον
Authors: Φάσουρα Αργυρώ , Αντωνίου Αλέξανδρος - Σταμάτιο�
Published: January 2018

Από πολλούς ερευνητές τα τελευταία χρόνια τονίζεται η ανάγκη για την υιοθέτηση μετασχηματιστικού τύπου ηγεσίας στην εκπαίδευση. Πρωτίστως, το έργο του μετασχηματιστικού ηγέτη είναι  να ευθυγραμμίσει τα συμφέροντα του οργανισμού με αυτά των μελών του με τον εμπνέει, να διεγείρει πνευματικά και να παρέχει εξατομικευμένη φροντίδα στους οπαδούς του. Η μετασχηματιστική ηγεσία στην εκπαίδευση επικεντρώνεται στην ανάπτυξη ενός κοινού οράματος και μιας συλλογικής δέσμευσης για την αλλαγή του σχολείου. Σκοπός της ανακοίνωσης αυτής είναι η παρουσίαση των αποτελεσμάτων σχετικά με την  υιοθέτηση αυτού του τύπου ηγεσίας στα σχολεία. Τα αποτελέσματα θα εξεταστούν ως προς το αντίκτυπο που έχουν στον ίδιο τον οργανισμό/σχολείο, στους δασκάλους, και τους μαθητές. Όσο αφορά το σχολείο, η μετασχηματιστική ηγεσία έχει επίδραση στις συνθήκες του σχολείου (π.χ στόχους, σχεδιασμό, δομή) αντανακλώντας τις συνθήκες που επικρατούν στην τάξη όπως οδηγίες, πολιτική και εκπαιδευτικές διαδικασίες. Άλλα ερευνητικά αποτελέσματα υποστηρίζουν ότι αυτού του είδους ηγεσία ασκεί επίδραση σε ευρύτερες σχολικές συνθήκες (π.χ εργασιακό κλίμα).  Ως προς τους δασκάλους, έχει επιπτώσεις στις αντιλήψεις τους σχετικά με τις συνθήκες στο σχολείο, την δέσμευση τους για αλλαγή και την οργανωσιακή μάθηση, καθώς και στην επαγγελματική τους ικανοποίηση. Το άμεσο αποτέλεσμα της μετασχηματιστικής ηγεσίας στην επίδοση των μαθητών, ως δέσμευση στο σχολείο και συμμετοχή, δεν καταγράφεται ως στατιστικά σημαντικό. ‘Ωστόσο, η ευρύτερη αλλαγή του σχολικού κλίματος καθώς και η ικανοποίηση που λαμβάνουν οι δάσκαλοι από την εργασία τους φαίνεται να έχει αντίκτυπο στη μάθηση και την επίδοση των μαθητών.

Digital Mediation, Soft Cabs, and Spatial Labour
Authors: Anderson Donald N.
Published: January 2018

Critics of digitally mediated labour platforms (often called the “sharing” or “gig economy”) have focused on the character and extent of the control exerted by these platforms over both workers and customers, and in particular on the precarizing impact on the workers on whose labor the services depend. Less attention has been paid to the specifically spatial character of the forms of work targeted by mobile digital platforms. The production and maintenance of urban social space has always been dependent, to a large degree, on work that involves the crossing of spatial boundaries - particularly between public and private spaces, but also crossing spaces segregated by class, race, and gender. Delivery workers, cabdrivers, day labourers, home care providers, and similar boundary-crossers all perform spatial work: the work of moving between and connecting spaces physically, experientially, and through representation. Spatial work contributes to the production and reproduction of social space; it is also productive of three specific, though interrelated, products: physical movement from one place to another; the experience of this movement; and the articulation of these places, experiences, and movements with visions of society and of the social. Significantly, it is precisely such spatial work, and its products, which mobile digital platforms seek most urgently to transform. Drawing on several recent studies of “ridesharing” (or soft cab) labour platforms, I interrogate the impact of digital mediation on the actual practices involved in spatial work. I argue that the roll-out of digital labour platforms needs to be understood in terms of a struggle over the production of social space.
Effects of Raster Orientation, Infill Rate and Infill Pattern on the Mechanical Properties of 3D Printed Materials
Authors: Dudescu Cristian , Racz Laszlo
Published: January 2018

Three-dimensional printing is an additive manufacturing process that allows rapid design and manufacture of complex component based on computer-aided design models. Compared with some conventional manufacturing processes, additive manufacturing part properties can depend on structural and process parameters rather than purely on material properties. The objectives of the paper are to evaluate the tensile properties of 3D printed components produced using a commercial 3D printer by performing standard tensile tests and to assess the influence of the technological parameters upon mechanical proprieties of printed specimens, considering different printing directions, infill rates and infill patterns. The influence of raster angles is tested through the designed specimens with different transverse plane, they are printed by placing in different angle, including 0°, 30°, 45° and 90°. Specimens with an infill rate varying from 20% to 100% and six different infill patterns has been tested.
Forecasting global coal consumption: An artificial neural network approach
Authors: Benalcazar Pablo , Krawczyk Małgorzata , Kamiński Jacek
Published: January 2018

In the 21st century, energy has become an integral part of our society and of global economic development. Although the world has experienced tremendous technological advancements, fossil fuels (including coal, natural gas, and oil) continue to be the world’s primary energy source. At the current production level, it has been estimated that coal reserves (economically recoverable) would last approximately 130 years (with the biggest reserves found in the USA, Russia, China, and India). The intricate relationship between economic growth, demographics and energy consumption (particularly in countries with coal intensive industries and heavy reliance on fossil fuels), along with the elevated amounts of greenhouse gases in the atmosphere, have raised serious concerns within the scientific community about the future of coal. Thus, various studies have focused on the development and application of forecasting methods to predict the economic prospects of coal, future levels of reserves, production, consumption, and its environmental impact. With this scope in mind, the goal of this article is to contribute to the scarce literature on global coal consumption forecasting with the aid of an artificial neural network method. This paper proposes a Multilayer Perceptron neural network (MLP) for the prediction of global coal consumption for the years 2020-2030. The MLP-based model is trained with historical data sets gathered from financial institutions, global energy authorities, and energy statistic agencies, covering the years 1970 through 2016. The results of this study show a deceleration in global coal consumption for the years 2020 (3 932 Mtoe), 2025 (4 069 Mtoe) and 2030 (4 182 Mtoe).
Microvascular Obstruction in Acute Myocardial Infarction
Authors: Dregoesc Ioana , Iancu Adrian , Manole Simona , Bălănescu Şerban
Published: January 2018

Introduction: The no-reflow phenomenon has been described in 20–40% of patients with acute ST-segment elevation myocardial infarction, despite restoration of TIMI 3 myocardial flow. It is associated with adverse left ventricular remodeling and an unfavorable long-term prognosis.

Case presentation: A 45-year-old gentleman was admitted one hour after the onset of an acute anterior ST-segment elevation myocardial infarction. Emergency coronary angiography was performed, and a severe stenosis of the left anterior descending artery was identified. The lesion was crossed with a pressure-wire, and a drug-eluting stent was directly implanted, with restoration of TIMI 3 epicardial flow. Predilatation was not performed. Coronary wedge pressure was measured during stent deployment. The mean pressure value was 27 mmHg. However, a tall systolic wave was identified in the morphology of the pressure curve. Myocardial blush grade and ST-segment resolution were concordant with early micro-vascular obstruction. Similarly, at transthoracic Doppler echocardiography, the flow in the left anterior descending artery revealed the same pattern. An apical left ventricular aneurysm was echocardiographically detected. The MRI described extensive interstitial edema that affected the anterior, septal, and apical regions of the left ventricle. Areas of intramyocardial hemorrhage and microvascular obstruction were also detected. According to recent literature data, the morphology of the coronary wedge pressure wave suggested at least the presence of pre-procedural distal embolization.

Conclusions: In the setting of acute myocardial infarction, the integrity of coronary microvasculature is an important issue. The distal coronary pressure wave pattern before primary percutaneous revascularization can be a deciding factor for an early therapeutic approach.
The probability of return conditional on migration duration: evidence from Kosovo
Authors: Kotorri Mrika
Published: January 2018

The aim of this paper is to conceptualise the migration duration decision within the expected utility maximisation framework, and from that to derive and estimate an empirical proposition. For this purpose, the conceptual framework in Kotorri (2015) is extended where households decide to return to the home country conditional on their migration duration. In the empirical analysis, the Cox proportional hazards model is employed. This analysis is the first to investigate migration duration based on a random sample stemming from the Kosovo census of population conducted in 2011. The findings suggest rather mixed support for the household approach. The hazard to return decreases with income but not nonlinearly. The results indicate that household return migration behaviour is influenced by demographic characteristics, psychic income, and political factors.
The social and financial efficiency of microfinance institutions: the case of Bosnia and Herzegovina
Authors: Efendic Velid , Hadziahmetovic Nejra
Published: January 2018

This paper investigates the financial and social efficiency of microfinance institutions (“MFIs”) in Bosnia and Herzegovina, as well as the effects of the latest crisis on these “two-dimensional” efficiencies. Specifically, we analyze the efficiency of MFIs in Bosnia and Herzegovina (BiH) as a good case of a European, post-war country in transition with a developed micro-financial sector. The efficiency analysis relies on secondary data collected and investigated through Data Envelopment Analysis (DEA). The study covers data for the period commencing in 2008 and ending in 2015. In our empirical investigation, we find a suboptimal level of both financial and social efficiency among MFIs in BiH. However, financial efficiency is significantly higher than social efficiency, while small-sized MFIs over perform larger ones in both the financial and social dimensions. As a result of the crisis, MFIs recorded a declining trend in efficiency up to 2010, after which they began to show signs of slow recovery. However, our results suggest that MFIs prioritized financial over social goals in recovery period following the crisis.
How did rapid credit growth cause non-performing loans in the CEE Countries?
Authors: Peric Blanka Skrabic , Konjusak Nikola
Published: January 2018

This paper investigates the influence of three types of credit growth on non-performing loans in eleven Central and Eastern European countries during the period from 1999 to 2013. As opposed to previous research on credit risk, we have moved the focus from the usually investigated bank-specific and macroeconomic variables to different types of credit growth from earlier periods. At the same time, the results of this research give answer on the studies before the crisis, which tried to determine the possible consequences of rapid credit growth in the CEE countries. The results indicate that at least two years are necessary for each type of credit growth to increase credit risk. Finally, empirical results confirm the importance of both bank-specific and macroeconomic variables.
Human resource management practices stimulating knowledge sharing
Authors: Matošková Jana , Směšná Petra
Published: January 2018

The major goal of the paper was to develop a theoretical framework that conceptualizes the indirect impact on human resource management practice on knowledge sharing in the organization. In the current competitive environment, the ability to use knowledge assets and to continuously renovate it is required for organizational success. Therefore, the field of human resource management should dedicate great effort to understanding how to enhance the knowledge flows within the organization. Theoretical indications were provided about HRM practices that influence the quality and quantity of knowledge sharing within an organization. Further, a conceptual model of relations between HRM practices and factors influencing knowledge sharing within an organization was introduced. It is supposed that HRM practices have direct impacts on personality traits of employees, organizational culture, characteristics of managers, and instruments used for knowledge sharing. Subsequently, these factors have direct effects on the perceived intensity of knowledge sharing. The paper offers 12 testable propositions for the indirect relation between HRM practices and knowledge sharing in the organization. The suggested model could assist future research to examine the influence of HRM practices upon managing knowledge is a more complex way. Via a theoretical contribution to the debate on the influence on HRM practices upon managing knowledge, the study contributes to further research development in this field.

Can Responsible Leadership Affect Work-Life Balance/Imbalance? A Study on Female Pharmacists in Egyptian Public Hospitals
Authors: Mousa Mohamed
Published: January 2018

As a result of the scandals in organizations like Enron, Arthur Anderson and WorldCom in addition to the 2008 global economic crisis, management scholars and practitioners have started to ask about the adequacy of current styles of leadership. Many management academic experts have realized that focusing only on maximizing shareholder profit is no longer acceptable as a sole business target. This has fostered the emergence of responsible leadership in the last 7 years as an attempt to fulfill both shareholders and stakeholders well-being.

Over the past two decades there has been a growing awareness of labor market participation and feminist active lobbying, and the concept “work-life balance” has come to be considered a buzzword in both management and organization studies. Moreover, the concept has also gained a rising significance owing to its positive correlation with individual and organizational performance.

This study focuses on public hospital in Menoufia province (Egypt) and investigates the effect of responsible leadership dimensions (aggregate of virtues, stakeholder involvement, model of leader’s role and principles of ethical values) on forms of work-life balance of pharmacists (time-based balance/imbalance, strain-based balance/imbalance and behavior-based balance/imbalance). Having collected and analyzed 230 questionnaire forms and used hierarchical regression analysis, the researcher found that only the aggregate of virtues is not considered a significant statistical predictor of the three forms of work-life balance/imbalance, whereas the other 3 dimensions of responsible leadership were found to be strong determinants of the 3 forms of work-life balance/imbalance.
Collision models in quantum optics
Authors: Ciccarello Francesco
Published: January 2018

Quantum collision models (CMs) provide advantageous case studies for investigating major issues in open quantum systems theory, and especially quantum non-Markovianity. After reviewing their general definition and distinctive features, we illustrate the emergence of a CM in a familiar quantum optics scenario. This task is carried out by highlighting the close connection between the well-known input-output formalism and CMs. Within this quantum optics framework, usual assumptions in the CMs’ literature - such as considering a bath of noninteracting yet initially correlated ancillas - have a clear physical origin.
Isolation of human testicular cells and co-culture with embryonic stem cells

Published: January 2018

Our overall goal is to create a three-dimensional human cell-based testicular model for toxicological and spermatogenesis studies. Methods to purify the major somatic testicular cells, namely Leydig cells (LCs), peritubular myoid cells (PCs) and Sertoli cells (SCs), from rats, mice and guinea pigs have been reported. In humans, the isolation of populations enriched for primary LCs, PCs or SCs also have described. One objective of this study was to determine if populations of cells enriched for all three of these cell types can be isolated from testes of single human donors, and we were successful in doing so from testes of three donors. Testes tissues were enzymatically digested, gravity sedimented and Percoll filtered to isolate populations enriched for LCs, PCs and SCs. LCs and PCs were identified by colorimetric detection of the expression of prototypical enzymes. Division of PCs and SCs in culture has been reported. We observed that primary human LCs could divide in culture by incorporation of 5-ethynyl-2′-deoxyuridine. SCs were identified and their functionality was demonstrated by the formation of tight junctions as shown by the expression of tight junction proteins, increased transepithelial electrical resistance, polarized secretion of biomolecules and inhibition of lucifer yellow penetration. Furthermore, we found that human SC feeder layers could facilitate germ cell progression of human embryonic stem cells (hESCs) by microarray analysis of gene expression.

Published: January 2018

Background

The current antiemetic prophylaxis for patients treated with highly emetogenic chemotherapy (HEC) included the olanzapine-based triplet and neurokinin-1 receptor antagonists (NK-1RAs)-based triplet. However, which one shows better antiemetic effect remained unclear.

Materials and Methods

We systematically reviewed 43 trials, involving 16,609 patients with HEC, which compared the following antiemetics at therapeutic dose range for the treatment of chemotherapy-induced nausea and vomiting: olanzapine, aprepitant, casopitant, fosaprepitant, netupitant, and rolapitant. The main outcomes were the proportion of patients who achieved no nausea, complete response (CR), and drug-related adverse events. A Bayesian network meta-analysis was performed.

Results

Olanzapine-based triple regimens showed significantly better no-nausea rate in overall phase and delayed phase than aprepitant-based triplet (odds ratios 3.18, 3.00, respectively), casopitant-based triplet (3.78, 4.12, respectively), fosaprepitant-based triplet (3.08, 4.10, respectively), rolapitant-based triplet (3.45, 3.20, respectively), and conventional duplex regimens (4.66, 4.38, respectively). CRs of olanzapine-based triplet were roughly equal to different NK-1RAs-based triplet but better than the conventional duplet. Moreover, no significant drug-related adverse events were observed in olanzapine-based triple regimens when compared with NK-1RAs-based triple regimens and duplex regimens. Additionally, the costs of olanzapine-based regimens were obviously much lower than the NK-1RA-based regimens.

Conclusion

Olanzapine-based triplet stood out in terms of nausea control and drug price but represented no significant difference of CRs in comparison with NK-1RAs-based triplet. Olanzapine-based triple regimens should be an optional antiemetic choice for patients with HEC, especially those suffering from delayed phase nausea.

Implications for Practice

According to the results of this study, olanzapine-based triple antiemetic regimens were superior in both overall and delayed-phase nausea control when compared with various neurokinin-1 receptor antagonists-based triple regimens in patients with highly emetogenic chemotherapy (HEC). Olanzapine-based triplet was outstanding in terms of nausea control and drug price. For cancer patients with HEC, especially those suffering from delayed-phase nausea, olanzapine-based triple regimens should be an optional antiemetic choice.
Potensi Kombinasi Teknologi Mutan Padi Toleran Kekeringan dan Polimer Superabsorben: Peran IPTEK Nuklir dalam Peningkatan Produksi Padi Lahan Kering
Authors: Herwibawa Bagus , Kusmiyati Florentina
Published: January 2018

Padi merupakan sumber bahan pangan pokok, yang dikonsumsi lebih dari 95% penduduk Indonesia. Kebutuhannya terus meningkat tiap tahun, namun belum berhasil dicukupi dari produksi sendiri, sehingga masih bergantung impor hingga 1.347.856 ton per tahun. Upaya yang dapat dilakukan selain impor, adalah peningkatan produksi padi melalui ekstensifikasi dan intensifikasi pertanian. Namun 72,98% daratan Indonesia yang sesuai untuk pertanian merupakan lahan kering, tentu akan menghambat peningkatan produksi padi. IPTEK Nuklir dapat berperan dalam optimalisasi pemanfaatan lahan kering, dimana keterbatasan keragaman alami dalam pemuliaan tanaman padi toleran kekeringan, dan polimerasi serta grafting polimer superabsorben, keduanya dapat diperbaiki melalui radiasi pengion. Kombinasi teknologi mutan padi toleran kekeringan dan polimer superabsorben sangat potensial sebagai satu diantara upaya-upaya untuk meningkatkan produksi padi. Namun, upaya penerapan teknologi tersebut tentu akan menimbukan masalah karena lemahnya diseminasi teknologi inovatif, dan lambatnya adopsi teknologi. Diperlukan  perhatian yang lebih besar dari peneliti, pengambil kebijakan, dan masyarakat pengguna.

A enunciação da cidade: práticas discursivas sobre a São Paulo do início do século XX
Authors: Joanilho André Luiz , Joanilho Mariângela Peccioli Galli
Published: January 2018

O estabelecimento do espaço urbano da cidade de São Paulo no início do século XX instaura a abertura de um amplo campo de estudos para a compreensão das práticas discursivas que se estabeleceram sobre a cidade no momento em que ela própria se constituía. Com a expansão física da cidade, foi possível estabelecer instituições novas: o Instituto Pasteur, o Instituto Vacinogênico, o Instituto Bacteriológico, a Faculdade de Medicina e Cirurgia, a Escola Normal, para citar algumas. Estas instituições promoveram o ideário cientificista e passaram a atuar no sentido de estabelecer práticas ligadas aos ideais higiênicos da época, como também, estimularam as discussões sobre o sujeito brasileiro, e instilaram ideias nacionalistas através de intensa propaganda. Permitiram um campo de atuação para a elite educada na cidade, fechando, de certa maneira, o circuito fazendeiros/educação/atividades urbanas. O ideário cientificista e a educação formal passaram a fazer parte das marcas de distinção de classe do lado da elite, que, pelo menos para parte dela, encontrou nas instituições urbanas um campo de atuação nas suas atividades além da política. O trabalho, a moral, a higiene, as habitações, o nacionalismo, a educação, passam a ser temas dessa elite cientificista. Neste sentido, a capital paulista, se torna o campo privilegiado para a aplicação de práticas discursivas que visam o controle e a conformação dos indivíduos. Estas práticas, por sua vez, constituem-se de enunciados que têm origem em locais diversos e se correlacionam (biologia, educação, nacionalismo, etc.).

Vagabmundear pensamentos – ciência e loucura e arte
Authors: Dias Susana Oliveira
Published: January 2018

Há poeira nos olhos. Partículas coloridas se agitam entre Javé, escrita, ciência, arte e loucura. Esfrego as narrativas. “Não, não!”. Tarde demais. Palavras feridas. Livros escavados. Perigo (de morte? de vida?). Também poeira são as águas, as lágrimas. Não há como salvar o globo da poeira e da loucura, é preciso afirmar o seu excesso, conviver com lesões na córnea gramatical. Querer o filme como pálpebra dobrada, que expõe os mundos às águas im-puras e facilita o acúmulo de germes na sintaxe.
A relação centro-periferia na discursividade da cidade
Authors: Ramos Tiago Roberto , Pimentel Renata Marcelle Lara
Published: January 2018

Este artigo aborda a relação entre espaços centrais e periféricos na cidade de Maringá (PR), buscando compreender, pela Análise de Discurso pecheutiana, como se dá a sua constituição simbólica. A observação em campo possibilitou explicitar um funcionamento marcado por constante intercâmbio e disputas de sentidos. Por mais que a estrutura espacial e o imaginário urbano tendam a silenciar o social, este irrompe na falha. Tal dinâmica marca um conflito pela constituição de memórias sobre a cidade.

Published: January 2018

This study examines selenite [Se(IV)] and selenate [Se(VI)] adsorption on two‐line ferrihydrite in the presence and absence of two low‐molecular‐weight dissolved organic carbon (DOC) species, citric and salicylic acid. Ferrihydrite surface potential measurements were also examined to identify shifts in isoelectric points, which suggest possible adsorption mechanisms. Sorption was completed in batch reactor systems at environmentally relevant pH. Our results indicate citric acid suppressed both Se(IV) and Se(VI) sorption on ferrihydrite, which may be caused by competition. This was especially evident at pH 5 to 7 for Se(IV) and pH 5 to 6 for Se(VI). Little sorption suppression was observed for both Se species in the presence of salicylic acid. In the presence of Se(IV) and Se(VI), citric acid adsorption was reduced (pH 5–8). Salicylic acid sorption was almost completely suppressed in the presence of Se(IV) throughout the entire pH range examined, with minimal sorption occurring at pH 5. In the presence of Se(VI), the largest reduction in salicylic acid sorption occurred at pH 5 to 6. Small shifts in the surface potential of ferrihydrite at higher pH suggest that Se(VI) and salicylic acid form weak, outer‐sphere complexes. However, at pH 5 and 6, there is a shift in the surface potential measurements to more negative values, indicating possible formation of stronger, inner‐sphere complexes. Larger surface potential shifts for Se(IV) and citric acid suggest the formation of strong, inner‐sphere complexes. This work demonstrates the ability of low‐molecular‐weight DOC species (particularly for citric acid) to increase Se(IV) and Se(VI) solubility through sorption suppression.

Core Ideas

Citric acid effectively reduced selenite and selenate sorption at lower pH.

Citric acid sorption was reduced by both selenite and selenate.

Little sorption suppression was exhibited by salicylic acid with both Se species.

Salicylic acid sorption was suppressed by selenite and reduced by selenate.

Surface potential shifts suggest inner‐sphere complexes for citric acid and selenite.
Yield Stability Differs in Commercial Maize Hybrids in Response to Changes in Plant Density, Nitrogen Fertility, and Environment

Continued yield increases in modern commercial maize (Zea mays L.) hybrids will require increased plant density, improved nitrogen‐use efficiency, and breeding for a hybrid's potential yield response to this management. The objective of this study was to determine the genetic variation of commercial hybrids in response to plant density and nitrogen (N) fertilizer levels to assist breeding programs to select hybrids with high yield stability or adaptability to crop management. From 2011 to 2014, 101 hybrids were grown in eight different environments at two planting densities (79,000 and 110,000 plants ha‐1) and three N rates (0, 67, and 252 kg N ha‐1). Broad‐sense heritability increased with increased N rate and plant density. Increased plant density altered yield from ‐0.60 Mg ha‐1 to +0.58 Mg ha‐1 under high N conditions, whereas the yield response to increased N ranged from +4.47 to +5.64 Mg ha‐1. Hybrids that combined above‐average yield under unfertilized and low‐N conditions exhibited greater‐than‐average yield stability across environments under high‐N conditions. Hybrid yield stability variance was larger under high‐N than under low‐N conditions because of greater genotype × environment interaction. Hybrids that were adaptable to high plant density and N conditions exhibited greater‐than‐average yield potential and yield variation across environments. Selecting hybrids with both high yield and yield stability may be difficult, as yield under lower N levels and yield increases with high N fertilization were negatively correlated.

Relevance. The correct implantation of acetabular component in total hip arthroplasty is an important factor for obtaining good outcomes and long-term survival of the prosthesis. The anteversion angle is one of the significant indicators for the three-dimensional orientation of the cup. The purpose of the study — to develope the method of calculating the anteversion angle of the acetabular component using postoperative anteroposterior radiographs of the hip and pelvis.The method. The authors used the projection ellipse formed by the opening of the prosthesis cup on the radiograph centered on the hip joint to calculate the desired value. The ratio sine of projectional diameter of the ellipse to its true diameter is a mathematical formula for finding the angle of anteversion. The comparison of the calculated index on anteroposterior radiographs centered on the hip joint and on the pelvis is necessary to identify the distinction between anteversion and retroversion of the acetabular component. In negative anteversion, or retroversion, the projectional diameter on the pelvic radiograph is larger than on the radiograph focused on the hip joint.Conclusion. Measuring of anteversion angle of acetabular component on postoperative radiograph allows to gain an optimal orientation of acetabular component which decreases postoperative complications rate. X-rays of any scale can be used for measurements while the ratio but not the absolute value of measured diameters is important for the result.

The purpose of the study – to compare the effectiveness of surgical correction of spine lumbar congenital deformity by complete or partial resection of the abnormal vertebra in children.Material and methods. 68 children with isolated congenital malformation of the lumbar area of the spine were evaluated both clinically and instrumentally. Age of the patients was 6 months — 16 years 2 months (mean — 4 years 5 months). There were 41 female and 27 male patients. Patients were divided in two groups depending on the volume of the surgery. First group (n = 52) consisted of patients treated with complete hemivertebrae resection. Second group (n = 16) consisted of patients treated with partial resection of the malformed vertebrae.Results. After the surgery in the 1st group scoliotic curve was 0 to 21° and kyphotic curve was from -33 to 9°. 9 years post-op scoliotic and kyphotic curves were 0 to 22° and -31 to 10° respectively. In the 2nd group scoliotic curve was 3 to 27° and kyphotic curve was from -30 to 12°. 9 years post-op scoliotic and kyphotic curves were 7 to 41° and -26 to 8° respectively. Significant differences in the amount of scoliotic curve correction were revealed between the groups: in the 1st group mean Cobb angle for the scoliotic curve after surgery was 3,3° (correction — 94%), in the 2nd group — 13,6° (correction — 80%) (p0,05). Mean Cobb angle for the scoliotic curve in the long-term period was 5° (correction — 92%) for the 1st group wich was significantly lower (p0,05) comparing to the 2nd group (mean Cobb angle 18,3° correction — 62%).Conclusion. Our data showed higher efficacy of the complete resection of the hemivertebrae comparing to its partial resection in pediatric patients with isolated malformation in the lumbar spine. Complete removal of the vertebrae body, its growth plates and disks allowed to achieve radical correction of the deformity and to perform short fusion of the adjacent segments which was crucial for further normal growth and development of the child’s spine with saving the results in the long-term period. Thus complete resection of the malformed vertebrae with radical correction and short segment fusion is the most appropriate option in surgical treatment of pediatric patient of any age with isolated vertebrae malformation in the lumbar spine.
