Identidades fraturadas: variações do duplo em Dois Irmãos, de Milton Hatoum
Authors: Camargo Flávio Pereira , Silva Alex Bruno da
Published: December 2018

Neste artigo, propomos uma análise das variações do mito do duplo no romance Dois irmãos, de Milton Hatoum, publicado em 2000. Com base nos pressupostos teórico-críticos de Bravo (1997), Rank (2013), Bachelard (1993), Rosset (1999) e Freud (1996), pretendemos demonstrar que, para além do tema dos irmãos gêmeos, o duplo, em Dois irmãos, pode ser lido em mais dois aspectos de duplicidade: a configuração do narrador, que tenta definir sua identidade como espelho do outro, e a imagem da casa em ruínas, espaço que reflete duplamente a decadência da família libanesa, bem como a identidade cultural do imigrante em terra alheia.

Criminality, Human Capital and Economic Performance
Authors: Mokline Adla
Published: December 2018

Criminality is any breach of the law likely to give rise to legal proceedings. It is determined by several factors namely (population density- unemployment-income- poverty and education). The objective of our work is to study criminality determinants on a sample of 51 American States over the period (2000-2013). Particular attention is paid to study the causal relationship between education (with its different measures) and criminality.In line with the approach to the economics of crime, this paper attempts to verify that urbanization, income inequality, unemployment, poverty and educational attainment significantly explain crime, on the one hand, and education is an investment activity that produces human capital, which is a fundamental factor of economic growth, job creation, wages and increased productivity of factors of production. Our results showed that the investment in human capital has a negative impact on crime in general. This effect is more considerable on crime against property. This leads us to define a crime deterrence policy through the implementation of structures able to help with installation of young people out of school and increase public spending on education.

From 2004 to 2007, the Spanish financial system grew at a very rapid rate. However, from 2008 to 2012 impairment losses amounted equivalent to 25% of Spanish GDP.The objective of this paper is investigate how have affected the main problems that have suffered the Spanish economy on the late payments on Spanish credit institutions. And to check whether the effect of these problems is different on stages of growth with respect to the stages of crisis.The main results, according the test Chow, confirmed that there is a structural break in the model in 2007. Also the increase in unemployment increases the late payments   and this increase is greater in the stages of growth compared to the stages of recession. The decrease in the price of housing increases the late payments. The increase in equity decreases the late payments, in these two variables decrease is greater in the recession stages compared to the growth stages.
EXPERIMENTAL INVESTIGATION OF A FOIL BEARING STRUCTURE WITH A POLYMER COATING UNDER DYNAMIC LOADS
Authors: BAGIŃSKI Paweł , ŻYWICA Grzegorz
Published: December 2018

This paper presents the results of research on the structural elements of a prototypical foil bearing in terms of its dynamic loads. In the framework of dynamic tests, several dozens of measurement series were carried out on a test rig specially prepared for this purpose. Dynamic excitations were applied using an electromagnetic exciter that enables changing the amplitude and frequency of the excitation force. Owing to this, it was possible to determine characteristics of the tested system in a wide range of loads and frequencies. A value of 400 Hz was assumed as the upper limit of the excitation frequency. The test rig enabled considering the direction of dynamic loads, which, as it turned out, had a significant impact on the obtained results. The research findings show that both the amplitude and frequency of an excitation force have a major impact on the stiffness and damping of the structural part of the foil bearing. The results of dynamic load tests complement the results of static tests performed earlier.
THE USE OF PLATE SPRINGS FOR PRELOADING OF A SYSTEM OF TAPERED ROLLER BEARINGS OF A WIND TURBINE GEARBOX
Authors: BASTIAN Bartosz , WASILCZUK Michał
Published: December 2018

The use of preloaded tapered roller bearings in wind turbine drive systems allows a transfer of load in the case of high variations of axial forces. The examined bearing system, a modification of a current design, consists of a pair of different sized bearings. Previous study showed the high sensitivity of tapered roller bearings on the existing radial interference. Dimensional tolerances used in the original design do not allow obtaining precise values of preload required for slippage-free operation of bearings with varying wind turbine load conditions. With the aim of achieving expected preload values, the use of plate springs (Belleville springs) is proposed. The springs will allow creating an axial force, independently of real dimensions in a modernised unit. Furthermore, it is very important in the case of gearbox retrofits to be executed up in the wind turbine nacelle without dismantling the gearbox.

Authors: Nowikiewicz Tomasz , Zegarski Wojciech , Szychta Paweł
Published: December 2018

Introduction: Incomplete excision of the primary lesion is one of the most important causes of local recurrence in breast cancer patients undergoing breast conserving therapy (BCT). The aim of the study is to determine the factors that increase the risk of obtaining positive surgical margins after BCT.
Material/Methods: Prospective analysis included 1,102 cases of invasive primary breast cancer treated with BCT (01/2015-12/2016). In the study group, we selected clinical-pathological factors, which have an impact on the excision rate of the primary lesion. It concerned identifiable features in pre-operative diagnostic procedures.
Results: In 15.7% of patients after BCT, positive margins of primary tumor excision were obtained. These patients required secondary surgery (with conversion to mastectomy in 78 (45.1%) patients undergoing surgery). In other cases, the primary tumor was excised radically.
Non-radical excision of the tumor was recorded in 21.4% of patients presenting lobular breast cancer (vs 7.4% in case of different histopathological types), lesions exceeding value of 2 cm and in event of positive HER2 receptor status (16.8% vs 11.4%). Among factors significantly increasing the rate of non-radical BCT operations, patients’ age and BMI (body mass index) value were specified (in uni- and multivariate analysis, with presence of statistically significant differences in case of every above mentioned factors).
Conclusions: Several clinical and pathological factors contribute to significantly increased risk of the incomplete excision following BCT. Identification of such variables should influence the selection of the surgical method. It concerns especially risk factors, which presence is possible to record prior to surgical procedure.

EXPERIMENTAL EVALUATION OF DLC/STEEL SLIDING CONTACTS’ OPERATIONAL ENVELOPE
Authors: ŁUBIŃSKI Jacek , WASILCZUK Michał
Published: December 2018

In an industrial project concerning sliding bearings, a sliding pair was selected of high alloy steel vs. industrial grade DLC coated high alloy steel as a basis for an innovative design of high performance sliding bearings lubricated with a synthetic oil for use in geared transmission units. The development process required credible data on the ultimate resistance of the sliding pair to very high contact stress. An experimental evaluation was undertaken in ring-on-ring contact with an incremental semi-steady state input parameters increase. Due to restrictions in time, economy, and manufacturing, the number of specimen sets available was limited. A flexible approach to specimen use and load/velocity/time combinations was employed to deliver required test results within the available resource limitations and at constantly updated project detailed goals.
TRIBOLOGICAL PROPERTIES OF GRAPHENE OXIDE-METAL-CARBON COMPOSITES
Authors: MUZYKA Roksana , DUDA Piotr , ROBAK Zbigniew , KAPTACZ Sławomir , DREWNIAK Sabina
Published: December 2018

Cu-C composites are materials used for the production of brushes, contacts, and pressing shoes for electric machines due to their mechanical and wear properties. These characteristics include good thermal and electrical conductivity, a low coefficient of friction, and lubricity under varying operating conditions. Currently, graphite and copper nanopowder based materials are used as a metal-carbon material in different ratios of these components. Graphite content in this kind of material has a positive effect on the smaller consumption of, e.g., rings and commutators. In contrast, a material without graphite content is used at high current densities. The examples of such machines are a DC motor starter or generators for electrolysis characterized by large current and low voltage. The present study tested the effect of graphene oxide (rGO) content on tribological properties in contact with steel in Cu-C composites. Tests were conducted on a ball-on-disk apparatus in conditions of dry friction. Disk wear and surface geometrical structure parameters (SGP) of the samples after tribological tests were determined on the basis of measurements made on the Talysurf.3D contact profilometer from Taylor Hobson. Damage mechanisms were identified and their relationships with structural characteristics were deducted. The hardness of Cu-C materials was higher than in copper. Cu-C based materials produce a better improvement of wear resistance, while the wear resistance of the graphene oxide based composites also decreased.
THE STRUCTURE AND COEFFICIENT OF FRICTION OF WELDED NICKEL ALLOYS INCONEL 625 AND INCONEL 718
Authors: STRZELCZAK Katarzyna , DUDEK Agata
Published: December 2018

In this study, the coefficients of friction for three series of welded nickel alloy joints, subjected to different heat treatments (lack of heat treatment, solution heat treatment, precipitation hardening), were determined. Heat treatment of the prepared samples was aimed at eliminating the structural and stress gradient, because the electron beam welding technique is dedicated for constructions with very high quality and strength requirements. Given the nature of the electron beam process, the authors are aware that the obtained weld’s structures are characterized by different properties from parent materials, and also from structures melted under equilibrium conditions. The scientific aim of the presented work is to determine the influence of heat treatment on the microstructure, mechanical properties, and performance of dissimilar joints of nickel alloys Inconel 625 and Inconel 718. In order to determine the coefficient of friction for samples, the scratch test method was used. As a result of the research, it was proved that subjecting the welds to the precipitation hardening has a significant effect on abrasion resistance.
THE EFFECT OF THE FORMATION OF POLYMER /SURFACTANT COMPLEXES ON SELECTED TRIBOLOGICAL PROPERTIES OF THEIR AQUEOUS SOLUTIONS
Authors: SUŁEK Marian W. , JEDYNAK Radosław
Published: December 2018

Aqueous solutions of sodium alkyl sulphate (surfactant) and polyvinylpyrrolidone (polymer) whose physicochemical properties, including complexing ability, have been widely described in the literature were proposed as a model lubricant. It has been assumed that aqueous solutions of these compounds will favourably modify lubricating properties of water under high load conditions. For this purpose, measurements were made on a four-ball apparatus (T-02 Tester) for aqueous solutions of these compounds. Two kinds of tests were carried out: at constant loads (2, 3, and 4 kN) and variable loads within the range of 0 to 7.2 kN. Unexpectedly, high decreases in motion resistance and wear as well as an increase in antiseizure properties were found in relation to water as a base. The results obtained are so promising that solutions with an optimized composition can find practical applications. The surprisingly high effectiveness of the additives used results from the formation of surfactant/polymer complexes. These adducts adsorb at the interface, and, under friction conditions, they form a lubricant film capable of carrying high loads.

Potential opportunities of possible shortening of production time in high-volume production were also indicated.
Powłoki kompozytowe Zn/C z dyspersją węglową wytwarzane metodą elektrochemiczną
Authors: Osuchowska Ewa , Buczko Zofia
Published: December 2018

W pracy przedstawiono nowe kierunki rozwoju w obszarze elektroosadzania cynku. Badano wpływ warunków prądowych i zastosowanego elektrolitu na skład powłoki oraz jej właściwości (morfologię, chropowatość, twardość, współczynnik tarcia). W większości przypadków w badanym zakresie zawartość węgla w powłoce rosła wraz ze wzrostem zawartości węgla w kąpieli. Badane powłoki kompozytowe Zn/C wykazywały wyższą mikrotwardość niż powłoki cynkowe. Rodzaj węgla wpływał na współczynnik tarcia otrzymywanych powłok kompozytowych. Najniższy współczynnik tarcia wykazywały powłoki z dodatkiem fazy dyspersyjnej zbliżonej do grafitu w porównaniu z powłokami cynkowymi i innymi kompozytami Zn/C.
Mikrostruktura i właściwości wytrzymałościowe gwoździ wytwarzanych od początku XX wieku do chwili obecnej
Authors: Skoczylas P. , Penkul Andrzej
Published: December 2018

W pracy porównano mikrostrukturę, właściwości wytrzymałościowe oraz twardość gwoździ wytwarzanych w różnych okresach, od pierwszej wojny światowej do współczesności. Wśród badanych materiałów są gwoździe kute ręcznie, walcowane na gorąco oraz gwoździe współczesne wytwarzane metodą kucia matrycowego. Starsze gwoździe mają głównie trzpień o przekroju kwadratowym, natomiast najpopularniejsze gwoździe produkowane współcześnie mają trzpień okrągły. Badania wykazały, jak zmieniła się jakość stali stosowanej do ich wyrobu i jak przełożyło się to na właściwości wytrzymałościowe. Dowiedziono również, iż jakość obecnie używanych stali do wyrobu gwoździ jest dużo wyższa niż od stosowanych 80–100 lat temu. Za starszymi gwoździami przemawia natomiast kwadratowy kształt przekroju poprzecznego trzpienia, który utrudnia pękanie drewna w trakcie wbijania gwoździa, a dzięki większym wartościom współczynników wytrzymałości na zginanie i skręcania jest mniej podatny na odkształcenie.
Effect of aluminum additives on the ignition of tungsten–Teflon mixtures
Authors: Alymov Mikhail , Vadchenko Sergey , Gordopolova Irina
Published: December 2018

Thermodynamic analysis and studies of combustion and structure formation of products were carried out in the powder mixtures of tungsten and polytetrafluoroethylene (Teflon, Tf) with aluminum additives. The mixture components were selected to fabricate high-density condensed products with high ignition temperature. Aluminum was used as an energetic additive accelerating the ignition process and increasing the mixture combustion temperature. In the mixtures, a tungsten/Tf ratio was fixed; the aluminum content was varied according to the following formula: (1– x)(0.8W + 0.2Tf) + xAl = const. Mechanically activated mixtures were pressed into the samples and heated in a special crucible with the controlled heating rate. It was shown that an increase in the heating rate changes insignificantly the ignition temperature of systems, but strongly affects the structure of combustion products. The ignition and combustion of the compositions with low aluminum content results in a large volume of gaseous products, which fly apart or form a high-porous structure. At high Al concentration, the results of the experiments and thermodynamic calculations are sufficiently different, which can be explained by the lack of thermodynamic data on tungsten aluminides in the used program and by the fact that real conditions of the reaction are far from equilibrium and adiabatic ones. The calculated and experimental data has shown that the optimal aluminum content to form the melted products with a high density (ρ(W2C) = 17.2 g/cm3) is about 10 wt %. At high Al concentration, the main combustion product (tungsten aluminide WAl4) has the lower density (ρ(WAl4) = 6.6 g/cm3), which is insufficient for a practical application.

Influence of layer substrate hardening on nitrided carbon steels on their tribological properties
Authors: Senatorski Jan , Tacikowski Jan , Trojanowski Janusz , Mączyński Paweł
Published: December 2018

Nitriding of carbon steels does not allow for adequate hardening of the substrate of layers and core required in some applications. Such hardening can be achieved by using further heat treatment. As a result of this heat treatment, the zone of nitrides vanishes and a nitro-carbon martensite structure is formed, additionally hardened by ageing. The carried out tribological tests have shown that subjecting nitrided carbon steel to further hardening treatment significantly improves its wear resistance in comparison to nitrided steel, and the zone of good wear resistance goes deeper.

Published: December 2018

Este artigo trata da realização de um breve levantamento literário sobre a atuação da música e da musicoterapia no campo da surdez. A percepção da música, muitas vezes, é mais acessível aos surdos do que a percepção de outros sons, sendo assim, torna-se necessário e indispensável pensar novas maneiras, novas tecnologias e novos instrumentos musicais quando um músico, professor de música ou musicoterapeuta se depara com esse publico. Para ampliar os meios de acesso à música por parte das pessoas surdas, é preciso romper com o pensamento de que estes são exclusivos da capacidade sensorial e física do ouvir, ou seja, dos chamados ouvintes.

Stan Getz em Samba de uma Nota Só: Um exemplo da conjunção das abordagens horizontal e vertical na construção de uma coerência na improvisação.
Authors:   PPGMUS UDESC, Gomes Luis Felipe
Published: December 2018

Estudo analítico da improvisação de Stan Getz e outros aspectos interpretativos presentes em Samba de uma Nota Só, faixa do álbum Jazz Samba lançado em 1962. A partir do registro fonográfico, cuja transcrição foi realizada pelo autor do presente artigo, observa-se como o saxofonista desenvolve, a partir da conjunção das abordagens horizontal e vertical (RUSSEL 2001), uma improvisação coerente. Outrossim, confirma-se elementos do cool jazz e do bebop, duas das instancias artísticas até então vivenciadas pelo músico e que estão atreladas ao seu estilo pessoal. No que diz respeito a outras questões de interpretação, são flagradas adaptações da composição de Tom Jobim e Newton Mendonça vinculadas aos moldes da linguagem jazzista. A análise revela também questões de hibridismo entre a linguagem da música norte americana e a brasileira. Com isso, o trabalho significa uma contribuição aos estudos sobre improvisação, vindo a somar-se na perspectiva das práticas interpretativas em música popular.

Para tanto, foi restringido o objetivo do texto a um estudo de caso de Treatise (1963-67), peça representativa das experimentações entre as pesquisas composicionais e suas soluções gráficas na obra de Cardew. A pesquisa também tangencia teorias da linguagem e da estética para sustentar os limites definidos para a análise, que se divide em dois momentos: a) Breve levantamento histórico do desenvolvimento das soluções gráficas para notações musicais não tradicionais no século XX, contextualizando historicamente a peça como parte integrante do debate sobre a notação; b) Delinear pontos de relação entre a poética de Cardew e a leitura da música como fenômeno de linguagem socialmente compartilhado.
Bumba-meu-boi do Maranhão: uma releitura de seus primeiros registros sonoros
Authors:   Universidade Federal do Maranhão, Cerqueira Daniel Lemos
Published: December 2018

O presente artigo tem como objetivo principal elaborar uma análise sonora das quatro gravações de bumba-meu-boi do Maranhão registradas em 1938 através da Missão de Pesquisas Folclóricas do Departamento de Cultura do município de São Paulo, coordenada por Mário de Andrade. Serão adotados como referência os padrões estéticos sonoros característicos da atual convenção de “sotaques”, presente tanto em estudos acadêmicos quanto em documentos oficiais do governo do Maranhão, fazendo uso de referências da Etnomusicologia. De maneira a complementar a presente análise, serão discutidas questões acerca do método de documentação sonora e das políticas culturais voltadas à patrimonialização cultural, status em que se encontra atualmente a manifestação em pauta. Conclusões reforçam a imprescindibilidade de ampliar o conceito estabelecido de “cultura maranhense”, historicamente sedimentado através das políticas culturais do governo estadual, e destacam a necessidade de haver mais estudos culturais sobre o Maranhão em uma perspectiva etnomusicológica.

Economic Analysis in a Diagnosis Related Groups System for Two-stage Exchange of Prosthetic-joint Infections
Authors: Fischbacher Arnaud , Peltier Karine , Borens Olivier
Published: December 2018

Abstract. Background: There is a constant increase of joint arthroplasties performed, with an infectious risk of 1-2%. Different therapeutic options for prosthetic-joint infections exist, but surgery remains essential. With a two-stage exchange procedure, a success rate above 90% can be expected. Currently, there is no consensus regarding the optimal interval duration between explantation and reimplantation. This retrospective study aimed to assess the economic impact of a two-stage exchange from a single-hospital perspective.Methods: 21 patients who have undergone a two-stage exchange of a hip or knee prosthetic-joint infection at the University Hospital of Lausanne (Switzerland) from 2012 to 2013 were included. The revenues earned according to the Swiss Diagnosis Related Groups (SwissDRG) system introduced in 2012 and the costs were compared for each hospital stay.Results: The remuneration ranged from 26'806 to 42'978 Swiss francs (CHF) (~ 22'905-36'723 EUR, median 36'338 CHF, ~ 31'049 EUR). The median total cost per patient was 76'000 CHF (~ 65'000 EUR) (51'151 to 118'263; hip median 79'744, knee median 66'708). The main determinant of the costs was the length of the hospital stay. Revenues never covered all the costs, even with a short-interval procedure. The hospital lost a median of 35'000 CHF per patient (~ 30'000 EUR) (22'280 to 64'666).Conclusion: The current DRG system may not be specific enough for rewarding prosthetic-joint infections. Several options could be considered to act on the length of the hospital stay. In order to cover costs in complicated cases, such as prosthetic-joint infections, more specific DRGs are needed.
Voiceless stop lenition and reduction as linguistic and social phenomena in Concepción, Chile
Authors: Rogers Brandon M.A. , Mirisis Christina A.
Published: December 2018

This study investigates voiceless stop lenition in Chilean Spanish.  Recent studies (e.g. Pérez 2007, Figueroa & Evans 2014 among others) have documented high levels of lenition of /bdg/ in Chilean Spanish.  As a result, the present study seeks to document the degree to which the voiceless stops /ptk/ undergo lenition in this variety of Spanish. Furthermore, the relationship between lenition and social factors (e.g., age, gender, and socioeconomic stratification) is examined.  Data was taken from the sociolinguistic interviews of 32 speakers from the Province of Concepción, Chile. In all, 4,419 intervocalic tokens of /ptk/ were analyzed for lenition using three different measurement criteria: total voicing, articulatory reduction, and duration.  Results confirm that, according to all three criteria, elevated levels of lenition are observed in the production of /ptk/ in Concepción.  Likewise, results indicate that as a social phenomenon, voiceless stop lenition in Concepcion is primarily conditioned by age and gender.
Degree Modification and Pluractionality in Spanish
Authors: Padilla-Reyes Ramon E
Published: December 2018

Standard and Puerto Rican Spanish has two modifiers, bastante/enough and más/more. These modifiers behave like the Spanish modifier muy/very in that they can modify gradable adjectives. However, these modifiers have an additional property. They are categorically flexible, in that they can combine not only with adjectives but also nouns and verbs. And when they modify verbs, plucational readings emerge. I show that these modifiers convey a multiplicity of pluractional readings that stem from the verb’s lexical property. Also, I show how these modifiers can be syntactically flexible. In the grammar, más and bastante bind to an event variable which determines its semantic. El español puertorriqueño y estándar cuenta con dos modificadores, bastante/enough y más/more. Estos se comportan como el modificador muy/very en que modifica adjetivos gradables. Sin embargo, estos modificadores tienen una propiedad adicional. Son categóricamente flexibles, en que pueden combinar no solamente con adjetivos, pero también con sustantivos y verbos. Y cuando modifican verbos, surge unas interpretaciones de pluraccionales. Demuestro que estos modificadores codifican una multiplicidad de interpretaciones pluraccionales. Estas interpretaciones surgen de las propiedades léxicas del verbo cuyo están modificando. También, demuestro como estos modificadores pueden ser sintácticamente flexibles. En la gramática, más y bastante se enlazan a una variable de eventos el cual determina su semántica.
Determiners and quantifiers in Spanish: types, tests and theories
Authors: Fábregas Antonio
Published: December 2018

This article provides an overview about the main facts and analytical options in the domain of determiners and quantifiers in Spanish. It covers the main classification of determiners and their basic syntactic and semantic properties (§1), the differences in behaviour between quantifiers and determiners in the strict sense (§2), the notion of definiteness and the contrasts in the use of the definite and indefinite articles (§3), the notion of specificity (§4) and the main types of quantifiers and how they can be identified (§5). In terms of analytical problems, it discusses whether determiners should be considered heads or not (§6), the areas within the determiner and quantifier domain (§7), the nature of the indefinite article as an element that shares properties with existential quantifiers (§8), the problems posed by proper names (§9) and the possible existence of phonologically null determiners in Spanish (§10). Conclusions are presented in §11.

Anthropogenic pressures threaten the health of coral reefs globally. Some of these pressures directly affect coral functioning, while others are indirect, for example by promoting the capacity of bioeroders to dissolve coral aragonite. To assess the coral reef status, it is necessary to validate community-scale measurements of metabolic and geochemical processes in the field, by determining fluxes from enclosed coral reef patches. Here, we investigate diurnal trends of carbonate chemistry, dissolved organic carbon, oxygen, and nutrients on a 20 m deep coral reef patch offshore from the island of Saba, Dutch Caribbean by means of tent incubations. The obtained trends are related to benthic carbon fluxes by quantifying net community calcification (NCC) and net community production (NCP). The relatively strong currents and swell-induced near-bottom surge at this location caused minor seawater exchange between the incubated reef and ambient water. Employing a compensating interpretive model, the exchange is used to our advantage as it maintains reasonably ventilated conditions, which conceivably prevents metabolic arrest during incubation periods of multiple hours. No diurnal trends in carbonate chemistry were detected and all net diurnal rates of production were strongly skewed towards respiration suggesting net heterotrophy in all incubations. The NCC inferred from our incubations ranges from −0.2 to 1.4 mmol CaCO3 m−2 h−1 (−0.2 to 1.2 kg CaCO3 m−2 year−1) and NCP varies from −9 to −21.7 mmol m−2 h−1 (net respiration). When comparing to the consensus-based ReefBudget approach, the estimated NCC rate for the incubated full planar area (0.36 kg CaCO3 m−2 year−1) was lower, but still within range of the different NCC inferred from our incubations. Field trials indicate that the tent-based incubation as presented here, coupled with an appropriate interpretive model, is an effective tool to investigate, in situ, the state of coral reef patches even when located in a relatively hydrodynamic environment.

Published: December 2018

Bighead carps (Aristichthys nobilis) were divided into four groups with different feeding strategies: group A, nature live food only (fertiliser only, 200 g urea + 160 g ethylamine phosphate + 250 g Huangjintai bio-fertiliser); group B, nature live food + 1/2 formulated feed; group C, nature live food + formulated feed; and group D, formulated feed only. The intestinal microbiomes of the different groups were compared through the Illumina MiSeq sequencing of the bacterial 16S rRNA gene. The specific growth rate (SGR), survival and blood biochemical factors of the fish were also investigated. Results showed that feeding treatment influenced the intestinal communities in the fish. In specific, more bacterial phyla dominated in groups A and B (phyla Bacteroidetes, Fusobacteria, Firmicutes and Proteobacteria in group A, phyla Proteobacteria and Fusobacteria in group B) than in groups C and D (phylum Proteobacteria). The diversity was also lower in groups C and D than in groups A and B. Unweighted pair-group method analysis revealed a clear difference in intestinal microbiota among the different feeding treatments. No difference in survival rate was found among the treatment groups, but the SGR was significantly higher (P < 0.01) in groups B, C and D than in group A. Functional analysis showed that the intestinal bacteria correlated with fish glucose metabolism in group A but with lipid metabolic activity in groups B, C and D. In summary, the intestinal microbiomes and their potential functions vary in bighead carp under different feeding treatments. This study provides new insights into the gut microbiomes of filter-feeding and formulated diet-fed fish.
