An important population of the endemic Mediterranean fan mussel Pinna nobilis thrives in the marine protected area of Gera Gulf (Lesvos island, north-eastern Aegean Sea, Greece), and was assessed for the first time. To estimate the abundance, spatial distribution and habitat use of fan mussels in Gera Gulf, a distance sampling underwater survey was conducted. Detectability was modelled to secure unbiased estimates of population density. Two approaches were applied to analyze survey data, a design-based and a model-based approach using generalized additive models. The first approach was based on stratified random sampling on two strata, an assumed ‘preferable’ zone close to the coastline and an assumed unsuitable habitat, with predominantly muddy sediments, in which low sampling effort was applied. For the needs of the model-based approach, a dedicated cruise was conducted to collect bathymetric data with a single-beam echo-sounder and map the bathymetry of the study area. A very high-resolution image from the Worldview-3 satellite was processed, based on an object-based image analysis, for mapping all main habitat types in the study area. The estimated abundance using the design-based approach was low-biased as the stratum of pre-assumed unsuitable habitat proved to include patches of suitable habitats with high population densities that were missed by sampling. The model-based approach provided an abundance estimate of 213300 individuals (95% confidence interval between 97600-466000 individuals), which renders the fan mussel population of Gera Gulf the largest recorded population in Greece. Population density peaked between 1.5-8 m depth and became practically zero at depths >15 m. A bathymetric segregation of fan mussel size classes was noted, with the density of small individuals peaking in shallow waters, while that of large individuals peaked deeper. The highest population densities were observed in Posidonia oceanica meadows, followed by mixed bottoms (with reefs, rocks and sandy patches), while densities were very low on sandy and zero on muddy sediments. The current assessment provides a baseline for future monitoring of the fan mussel population in Gera Gulf. In view of the current (2017-2018) ongoing mass mortality of the species in the western Mediterranean, continuous monitoring of the main fan mussel populations, such as the one in Gera Gulf, is of utmost importance.
Interactions between free-living nematodes and benthic diatoms: insights from the Gulf of Trieste (northern Adriatic Sea)

Published: January 2019

From July 2010 to July 2012, free-living nematodes were investigated in terms of abundance, genera and trophic composition at the long term St. C1 (depth 18 m), located in the Gulf of Trieste (northern Adriatic Sea). The integration of these results with environmental (e.g. sediment grain-size, Biopolymeric C and Chl a) and biological variables (benthic diatom biomass and composition) collected synoptically with nematodes, allowed to clarify the linkage between these organisms and another ecosystem component, i.e. benthic diatoms. The observed peaks of nematode abundance in summer samplings were ascribable almost exclusively to piercing nematodes that feed on microalgae (Chromadoridae and, among them, Ptycholaimellus) and were concomitant with the highest numbers of benthic diatoms. DISTLM outputs further corroborated this interaction by indicating Chl a, i.e. a proxy of benthic diatoms, as the only environmental variable that significantly shaped nematode assemblage over the 2-year period. This linkage was not explained only quantitatively (i.e. more diatoms supported more nematodes) but also qualitatively. During winter, in fact, the presence of heavily silicified diatoms co-occurred with nematode minima and the lowest percentage of piercing organisms, suggesting an overall minor ability of the assemblage in using this feeding strategy. In a benthic ecosystem functioning point of view, the observed seasonal pattern of variation in both nematodes and benthic diatoms suggests that more of the energy flowing to nematodes during the summer derives directly from benthic diatom primary production while in the winter this linkage is less important.

Published: January 2019

Artisanal Small-Scale Fisheries (SSFs) are a primordial and very diverse activity in the Mediterranean, also within Marine Protected Areas (MPAs). This diversity is explained in terms of target species, gears, and fishing strategies. The main objective of this work was to investigate the spatio-temporal dynamics of artisanal SSFs of the future MPA of “Taza” (Algeria, SW Mediterranean). Data were collected through direct assessment of daily landings and using questionnaires. They were the subject of multivariate analyses that allowed us to identify the métiers practiced by artisanal fishers. During the one year (May 2013 to April 2014) field work period, 1330 fishing trips and 1613 fishing operations in 16 fishing grounds were recorded in the Ziama fishing harbor, where 15.2 tons of total catch was assessed. Our results show that, in the study area, the boats are predominantly gillnetters and that among the five métiers characterized by target species, gear type, fishing grounds, and fishing seasons, two métiers (“Mullus surmuletus trammel net” and “Sparids monofilament gillnet”) are practiced throughout the year, while the remaining three (“Sarda sarda driftnet”, “Merluccius merluccius set gillnet”, and “Pagellus set gillnet”) are specific to a determined period of the year. The ‘Mullus surmuletus trammel net’ métier represents 40% of the total fishing operations, of which 57.5% are carried out in the coastal sector at - 25 m. This study could contribute to defining the appropriate management approaches for SSFs in the future MPA of “Taza” by providing baseline information to build a sound management plan. In Algeria, it will certainly serve as a scientific reference in terms of zoning, protection of biodiversity, and specific monitoring at particular locations and periods of the year for the sustainable management of MPAs.

Schizofrenia jest przewlekłą chorobą rozpoczynającą się zwykle w wieku młodzieńczym lub wczesnej dorosłości. Często jest postrzegana jako poważna, nieuleczalna choroba, o ogólnie złym rokowaniu, w której pacjenci bywają pobudzeni, agresywni i nieprzewidywalni w swoich zachowaniach. Postępująca świadomość i powoli wprowadzane zmiany w podejściu do konieczności wieloaspektowej terapii schizofrenii oraz postęp w farmakoterapii w ostatnich dekadach pozwalają na poprawę rokowania u wielu chorych. Ze względu na wielopostaciowy charakter choroby w klasyfikacjach chorób psychicznych rozróżnia się wiele podtypów schizofrenii, starając się dostosować kryteria i opisy do najczęściej spotykanych sytuacji klinicznych. Opisy kliniczne schizofrenii opierają się na różnych modelach psychopatologicznych. Często są to modele wielowymiarowe, wieloczynnikowe. Praktycznie zawsze modele takie uwzględniają dwa wymiary: objawów negatywnych (ubytkowych) i objawów pozytywnych (wytwórczych).
Współczesne podejście do leczenia schizofrenii zakłada zastosowanie wielokierunkowej interwencji terapeutycznej, której konieczne jest uzyskanie pełnej remisji objawów i powrót chorego do pełnego funkcjonowania psychospołecznego. Badania długofalowe wykazują, że stopień nasilenia objawów negatywnych jest wskaźnikiem prognostycznym pogorszenia funkcjonowania społecznego i zawodowego oraz obniżonej jakości życia. Niniejsza praca przedstawia przegląd koncepcji i badań nad objawami negatywnymi w schizofrenii i ich leczeniem; w drugiej części będę zaprezentowane międzynarodowe standardy i rekomendacje Polskiego Towarzystwa Psychiatrycznego odnośnie podejścia do skutecznego leczenia objawów negatywnych w przebiegu schizofrenii.
Leitura compartilhada de histórias e aprendizagem de palavras em crianças típicas e com Síndrome de Down
Authors: Bonagamba Camila , Schmidt Andréia
Published: January 2019

A leitura compartilhada de histórias é um recurso para ensino de vocabulário para crianças pré-escolares, porém não se sabe sobre a sua eficácia para crianças com Síndrome de Down (SD). Este estudo investigou a aprendizagem de relações entre palavras (um substantivo e um adjetivo) e figuras, por crianças com sd e com desenvolvimento típico (DT), a partir da leitura repetida de uma história. Seis crianças dt (3-4 anos) e seis sd (5-8 anos) participaram de três sessões individuais de leitura de um livro não comercial, que continha duas palavras desconhecidas e suas respectivas figuras. Cada sessão tinha uma condição diferente de leitura. Antes do procedimento e ao final das sessões foram realizadas sondas de nomeação, emparelhamento com o modelo e exclusão. Uma semana após a última sessão as sondas foram reaplicadas, acrescidas de sondas de generalização. As crianças dt demostraram aprendizagem da relação palavra-fruta nas sondas. Dois participantes SD demonstraram indícios de aprendizagem da relação palavra-fruta, mas não da relação palavra-cor. O procedimento foi adequado para ensinar substantivos para crianças DT, porém não para crianças SD, que demandam procedimentos adicionais.Palavras-chave: leitura compartilhada de livros, aprendizagem de palavras, Síndrome de Down.
The Effect of the Say-on-Pay Vote in the United States
Authors: Iliev Peter , Vitanova Svetla
Published: January 2019

The Dodd–Frank Act mandated advisory shareholder votes on executive compensation. To isolate the effect of holding a Say-on-Pay vote we use an exemption provided to a group of firms based on their public float. We find that the regulation increased the level of CEO pay and the fraction of performance-linked pay in the companies that had to comply with the new rule. This increase was larger for CEOs with higher ownership and longer tenure. Moreover, the market reacted negatively to the exemption from the Say-on-Pay rule suggesting general support for holding the Say-on-Pay votes. These effects are not present in placebo specifications in previous years or in different groups.

VOZ, LITERATURA, POLÍTICA E OUTRAS TRAVESTILIDADES DO CORPO TRANS-NACIONAL
Authors: De Oliveira Leonardo Davino
Published: January 2019

A partir das perguntas “a literatura é o desejo travestido? O desejo da literatura impõe o travestimento?”, feitas por Ana Chiara (2004), para quem o crítico “não [pode] esquecer no travestimento o jogo, a trapaça, o artifício”, este ensaio investiga a representação da travestilidade na canção popular. Obras dos cancionistas brasileiros Caetano Veloso, Chico Buarque, Erasmo Carlos, Aldir Blanc, Moacyr Luz, Linn da Quebrada; do português Pedro Abrunhosa; e do inglês Sting serão analisadas comparativamente a narrativas (em especial livros do franco-cubano Severo Sarduy) em que a travesti aparece como protagonista. O objetivo é pensar as marcas éticas e estéticas inscritas pela travesti no corpo nacional. Inscrição esta que define o impacto da imagem em circulação internacional do Brasil, marcada pelos plurilinguismo e cruzamento de fronteiras. Para tanto, faz-se necessário discutir tanto a expressão “travestis tipo exportação” (TREVISAN, 2000), quanto o conceito de androginia (ELIADE, 1999; e WOOLF, 2014).
“UMA MULHER QUE NUNCA VERGAVA; QUE NÃO TINHA AMO NEM DEUS” – RECORTES DA MÍTICA RAINHA NZINGA NA LITERATURA DE AGUALUSA, MUSSA E EGÉNIA NETO
Authors: Aires Franceschini Marcele
Published: January 2019

A mítica Nzinga Mbandi, a Rainha Ginga, foi líder de vastíssimo território no século XVIII. Grande parte dos escravizados que vieram ao Brasil são oriundos da região bantu – dominada por ela então. Sua história é tão gloriosa quanto a da própria África. Não por acaso inúmeros são os historiadores que se interessam por sua figura, assim como centenas são os escritores que já se aventuraram a romancear ou a cantar seus feitos. Para essa análise, escolheram-se três autores: o angolano José Eduardo Agualusa e seu romance histórico A Rainha Ginga: e de como os africanos inventaram o mundo (2014); o carioca Alberto Mussa e seu romance policial O trono da Rainha Jinga, (1999); e a portuguesa radicada em Angola Eugénia Neto e seu poema “Poema à Mãe Angolana”, lançado em 1976, no contexto da luta pela Independência de Angola. Prezaram-se, nesse estudo, dois movimentos: primeiramente, descreveu-se historicamente a figura da Rainha para então a retratar segundo recortes dos autores supracitados. Ambos Agualusa e Mussa tendem a demonstrar o poder da Rainha representado por sua força “de macho”, já que a líder assume a governança marcada pela linhagem patriarcal. Já Eugénia Neto humaniza a figura de Nzinga como a grande “Mãe Angolana”, salientando suas características femininas. Independente do julgamento, importa perceber como autores de distintas nacionalidades e gêneros constroem a imagem da soberana africana, mesclando história e ficção num balé fértil de dimensões épicas e poéticas.

The market for gender-equality expertise: providing services to public and private organisations in France
Authors: Blanchard Soline
Published: January 2019

This article analyses the rise and functioning of the professional gender-equality consulting market in France on the basis of 63 interviews, participant observation and document review. It first examines the socio-historical process of creating the market and highlights the role of public action. It then investigates the market structure and reveals a division between two ideal-typical segments, before presenting some overlaps and circulations between them. It finally discusses existing power relations within the market and ambivalent public regulation, arguing that weak state commitment and low social pressure hinder the potential for transformative change brought about by gender-equality consulting.
O sister, where art thou? Theory and evidence on female participation at citizen assemblies
Authors: Gerber Marlène , Schaub Hans-Peter , Mueller Sean
Published: January 2019

This article investigates gender differences in participation at the citizen assembly of Glarus, Switzerland. We use original survey data collected among 800 citizens. We find significant gender gaps both for attending and holding a speech at the assembly. Lower female attendance is particularly pronounced among older cohorts and can largely be explained by gender differences in political interest, knowledge and efficacy. In contrast, the gender gap in speaking is substantial regardless of age and cannot be reduced to factors that typically shape participation. Hence, gender differences are disappearing in voting but persist in more public, interactive forms of political engagement.

Effect of Various Yeasts Antagonists on Anthracnose Disease and the Shelf Life of MangoPostharvest decay on mango may occur due to physiological damage and/or postharvest disease especially anthracnose. This postharvest decay may decrease the quality of mango fruit. The use of antagonists yeast as biocontrol agent is an alternative control measure for postharvest diseases of fruits. This study aimed to screen yeast species as biological control agents and in the same time delaying the maturity of fruits to extend its shelf life.  Six isolates of yeasts were evaluated, namely Cryptococcus albidus, Cryptococcus terreus, Aureobasidium pullulans, Rhodotorula minuta, Candida tropicalis, Pseoudozyma hubeiensis); fungicides treatment using azoksistrobin was applied for comparative treatment. The study was conducted at two temperature conditions, namely room temperature and 15 ° C. It was evidenced that C. albidus, A. pullulans, and C. tropicalis were effective to control anthracnose disease on mango under both temperatures.  Furthermore, C. tropicalis and A. pullulans were able to extend manggo shelf life for 21 days at room temperature and for 54 days at 15 °C, respectively.
RTD Measurement, Modeling, and Analysis of Liquid Phase of Three-Tube Industrial Pulp Digester
Authors: Sheoran Meenakshi , Chandra Avinash , Ahuja Sanjeev , Bhunia Haripada , Pant Harish J.
Published: January 2019

Residence-time distribution (RTD) experiments were performed to analyze an industrial scale three-tube series continuous pulping digester’s hydrodynamic performance. An impulse of radiotracer 82Br (γ energy source) was introduced at the inlet of the first tube. The radiotracer concentration in the liquid phase was traced at the outlet of each tube. The input behavior of the radiotracer converted to a non-ideal pulse tracer input for the second and third tubes of the digester. Numerical convolution is adopted to deal with the non-ideal pulse input of the radiotracer. A modeling procedure for determining the RTD from the outlet tracer concentration data is proposed. A plug flow component followed by axial dispersion model is considered, and is adjusted after its convolution with the inlet tracer concentration data to obtain the RTD of the individual tubes. The obtained RTD data are analyzed to explain the flow behavior, degree of dispersion, and flow abnormalities existing in the digester. The mean residence-time (MRT), and dispersion number are estimated for the model components for the three tubes. The vessel dispersion number is found to decrease from tube 1 to tube 3. Overall, the conversion of the highly dispersed flow regime into the plug-flow regime is observed in the whole digester.
Sixth-Kind Chebyshev Spectral Approach for Solving Fractional Differential Equations
Authors: Abd-Elhameed W. M. , Youssri Y. H.
Published: January 2019

The basic aim of this paper is to develop new numerical algorithms for solving some linear and nonlinear fractional-order differential equations. We have developed a new type of Chebyshev polynomials, namely, Chebyshev polynomials of sixth kind. This type of polynomials is a special class of symmetric orthogonal polynomials, involving four parameters that were constructed with the aid of the extended Sturm–Liouville theorem for symmetric functions. The proposed algorithms are basically built on reducing the fractional-order differential equations with their initial/boundary conditions to systems of algebraic equations which can be efficiently solved. The new proposed algorithms are supported by a detailed study of the convergence and error analysis of the sixth-kind Chebyshev expansion. New connection formulae between Chebyshev polynomials of the second and sixth kinds were established for this study. Some examples were displayed to illustrate the efficiency of the proposed algorithms compared to other methods in literature. The proposed algorithms have provided accurate results, even using few terms of the proposed expansion.
On Kant’s Derivation of the Categories
Authors: Borboa Santiago de Jesus Sanchez
Published: January 2019

In this paper, I put forth a novel interpretation of how the third categories under each heading in the table of categories (totality, limitation, community, and necessity) are derived. Drawing on a passage from the first Critique and a letter to Schultz, I argue that in order to derive these categories, a special act of the understanding is required. I propose that we interpret this special act as consisting of an application of the third logical function under the corresponding heading that unites the combination of the first and second categories (under that same heading) so as to produce the third.
Self-organization of surfaces on the nanoscale by topography-mediated selection of quasi-cylindrical and plasmonic waves
Authors: Rudenko Anton , Mauclair Cyril , Garrelie Florence , Stoian Razvan , Colombier Jean-Philippe
Published: January 2019

Using coupled electromagnetic and hydrodynamic calculations, we elucidate theoretically the topographic transition from a random metallic surface to a periodic sub-wavelength grating by ultrashort laser ablation. The origin of this transition lies in the successive selection of hybrid surface waves scattered by random nanoholes. Contrary to the common belief that surface plasmon polaritons play the dominant role in the process and define the grating periodicity, we show that both quasi-cylindrical and surface plasmon waves are involved, whereas the diversity in the resulting spacings λ/2–λ (λ is the laser wavelength) is the manifestation of a broad frequency overlap of these waves, controlled by their relative phase shifts with respect to the plasmonic counterparts. The topography evolution imposes the dominant contribution to the surface sub-wavelength pattern by selecting the appropriate wave character from plasmonic modes to evanescent cylindrical waves. With the radiation dose, the grating periodicity exhibits a pronounced blue shift due to reinforced dipole–dipole coupling between the nanoholes and surface curvatures in the laser-processed area. This allows the creation of regular patterns with tunable periodicity.

Using chemical synthesis to optimise antimicrobial peptides in the fight against antimicrobial resistance
Authors: Li Freda F. , Brimble Margaret A.
Published: January 2019

The emergence of multidrug-resistant bacteria has necessitated the urgent need for novel antibacterial agents. Antimicrobial peptides (AMPs), the host-defence molecules of most living organisms, have shown great promise as potential antibiotic candidates due to their multiple mechanisms of action which result in very low or negligible induction of resistance. However, the development of AMPs for clinical use has been limited by their potential toxicity to animal cells, low metabolic stability and high manufacturing cost. Extensive efforts have therefore been directed towards the development of enhanced variants of natural AMPs to overcome these aforementioned limitations. In this review, we present our efforts focused on development of efficient strategies to prepare several recently discovered AMPs including antitubercular peptides. The design and synthesis of more potent and stable AMP analogues with synthetic modifications made to the natural peptides containing glycosylated residues or disulfide bridges are described.

Dialogues with the Archives: Arrarrkpi Responses to Recordings as Part of the Living Song Tradition of Manyardi
Authors: Brown Reuben , Manmurulu David , Manmurulu Jenny , O’Keeffe Isabel
Published: January 2019

This article explores the role of legacy recordings of song for a family of Arrarrkpi (Mawng-speaking people), who are contemporary singers and dancers of manyardi, a public ceremonial performance of western Arnhem Land, in their collaborative work with a team of Balanda (Euro-diasporic) researchers. Drawing inspiration from the dialogical approach of the Yolŋu ceremonial leader and scholar Joe Gumbula, the article reflects on various dialogues that inform the research, practice and archival recording of manyardi. We demonstrate how legacy recordings reinvigorate contemporary performance practice in collective settings, rather than serving as canonical or ideal versions of song sets to be replicated by an individual singer. We suggest that maintaining the linking and organisation of enriched song metadata from this community to the archival collection will enable future song inheritors to maintain dialogues with archives that hold recordings of manyardi.
Matjabala Mali’ Buku-ruŋanmaram: New Pathways for Indigenous Cultural Survival through Yolŋu Explorations of the University of Sydney Archives
Authors: Gumbula Joseph Neparrŋa
Published: January 2019

This article was adapted by Aaron Corn from a lecture presented by Joe Gumbula at the Koori Centre at the University of Sydney on 5 April 2007. The day before, Joe had been admitted to the degree of Doctor of Music honoris causa at the University, and had only recently started work at the Koori Centre on his first Australian Research Council (ARC) project as an ARC Indigenous Research Fellow. Called “Elder Assessments of Early Material Culture Collections from Arnhem Land and Contemporary Access Needs to them among their Source Communities” (DI0775822) and including Aaron Corn as a nominal Mentor, this was the first ARC project to be led by a Yolŋu Chief Investigator. It enabled Joe to undertake detailed research into the Yolŋu heritage collections held in the University of Sydney’s Archives and Macleay Museum. Eighteen members of Joe’s family from Miliŋinbi (Milingimbi) and Galiwin’ku, who were visiting Sydney to attend his graduation ceremony, were present at this lecture. Joe’s assured and impassioned delivery on this occasion aptly demonstrates his exemplary knowledge of Yolŋu heritage, his mastery in applying Yolŋu law to its interpretation, and his ability to engage others in the process and significance of collections research. All University of Sydney materials that Joe presented in the lecture were later published in his 2011 book, Matjabala Mali’ Buku-ruŋanmaram: Images from Miliŋinbi (Milingimbi) and Surrounds, 1926–1948, and, in this article, are cross-referenced to this source, which remains available for purchase from Sydney University Press.
Feasibility Study of Textureless Object Detection and Pose Estimation Based on a Model with 3D Edgels and Surfaces
Authors: Yamazaki Kimitoshi , Sogen Kiyohiro , Yamamoto Takashi , Inaba Masayuki
Published: January 2019

This paper describes a method for the detection
of textureless objects. Our target objects include furniture
and home appliances, which have no rich textural
features or characteristic shapes. Focusing on the ease of
application, we define a model that represents objects in
terms of three-dimensional edgels and surfaces. Object detection
is performed by superimposing input data on the
model. A two-stage algorithm is applied to bring out object
poses. Surfaces are used to extract candidates fromthe
input data, and edgels are then used to identify the pose
of a target object using two-dimensional template matching.
Experiments using four real furniture and home appliances
were performed to show the feasibility of the proposed
method.We suggest the possible applicability in occlusion
and clutter conditions.
Salivary IgA as a Predictor of Upper Respiratory Tract Infections and Relationship to Training Load in Elite Rugby Union Players

Tiernan, C, Lyons, M, Comyns, T, Nevill, AM, and Warrington, G. Salivary IgA as a predictor of upper respiratory tract infections and relationship to training load in elite rugby union players. J Strength Cond Res 34(3): 782–790, 2020—Upper Respiratory Tract Infections (URTI) are among the most common illnesses reported in athletes. An URTI can result in missed training days, which in turn may lead to performance decrements. The purpose of this study was to investigate the use of salivary immunoglobulin A (sIgA) as a predictor of URTI, while also exploring the relationship to weekly training load in elite rugby union players. Nineteen male elite rugby union players provided morning saliva swabs, biweekly (Monday and Friday), over a 10-week training period. Participants completed an illness log documenting symptoms of URTI. Session Rate of Perceived Exertion (sRPE) was collected to determine training load (sRPE × session duration). Weekly training load was also calculated. Logistic regression was used to analyze the relationship between incidences of URTI with sIgA and training load. Multilevel regression was conducted to compare associations between sIgA and training load. The results found that the likelihood of suffering from an URTI increased when sIgA significantly decreased (p = 0.046). Where sIgA decreased by 65% or more, a player was at a greater risk of contracting an URTI within the following 2 weeks. No association was found between sIgA and training load. In conclusion, sIgA may be a useful predictor for determining the likelihood of players contracting an URTI. This will allow the coach to make informed decisions on training status, helping reduce the risk of players missing training, which may have performance decrements. Coaches will benefit from the fast, easy, and instant results available, to analyze a player's immune function.

Twenty-six professional players were assessed during a competitive Australian Football League (AFL) season. [CK] was collected 24–36 hours before match and 34–40 hours after match during 8 in-season rounds. An athlete-tracking technology was used to quantify match load. Generalized estimating equations and random forest models were constructed to determine the extent to which match-load indices and pre-match [CK] explained post-match [CK]. There was a 129 ± 152% increase in [CK] in response to AFL competition. Generalized estimating equations found that number of impacts >3g (p = 0.004) and game time (p = 0.016) were most strongly associated with post-match [CK]. Random forest, with considerably lower errors (130 vs. 316 U·L−1), found deceleration, acceleration, impacts >3g, and sprint distance to be the strongest predictors. Pre-match [CK] accounted for 11% of post-match [CK], and considerable interindividual and intraindividual variability existed in the data. Creatine kinase, an indicator of muscle damage, was considerably elevated as a result of AFL competition. Parametric and machine-learning analysis techniques found several indices of physical load associated with muscle damage during competition, with impacts >3g and high-intensity running variables as the strongest predictors. [CK] may be used as a global measure of muscle damage in field team sports such as AF, yet with some caution given cost, invasiveness, and inherent variability. Quantifying physical load and the responses to that load can guide athlete management decision-making and is best undertaken within a suite of practical, sport-specific measures, where data are interpreted individually and with an understanding of the limitations.

Nakao, S, Ikezoe, T, Nakamura, M, Umegaki, H, Fujita, K, Umehara, J, Kobayashi, T, Ibuki, S, and Ichihashi, N. Chronic effects of a static stretching program on hamstring strength. J Strength Cond Res 35(7): 1924–1929, 2021—This study investigated the effects of a 4-week static stretching (SS) program on isokinetic and isometric knee flexor peak torque and angle of peak torque. Thirty healthy men (age, 22.7 ± 2.2 years) were randomized to receive either of the following: (a) a 4-week stretch intervention for the hamstrings (SS intervention group; n = 15) or (b) no intervention (control group; n = 15). The maximum pain-free knee angle, passive stiffness, which was determined by a slope of torque-angle curve, isometric and isokinetic (at 60°·s−1 and 180°·s−1) peak torque, and angle of peak torque for knee flexors were measured before and after 4 weeks. After 4 weeks, passive stiffness decreased significantly in the intervention group. There were no significant changes in isometric and isokinetic (neither at 60°·s−1 nor at 180°·s−1) peak torque, or angle of peak torque at 180°·s−1. A significantly increased peak extension angle at 60°·s−1 was observed in the intervention group. These results suggest that SS intervention is effective for decreasing musculotendinous unit stiffness of the hamstrings and that an SS program influences the angle of peak torque, whereas no significant changes occur in peak torque. Because a previous study suggests that angle of peak torque is associated with hamstring strain injuries, the results of this study would be helpful when considering the training program for preventing or treating hamstring strain injuries.

Published: January 2019

In this study, polyester, i.e., Poly(ethylene terephthalate) (PET) nonwoven fabric, was coated with white tuff, perlite, and volcanic stone powder at rates of 10, 20, 30 and 40 % so as to increase the thermal insulation properties of PET nonwoven fabric. In order to apply white tuff, perlite, and volcanic stone powder to PET nonwoven fabric, polyurethane-based coating material was used as a cross-linking agent. The porosity and thermal conductivity coefficients of samples were then investigated as regards the type and concentration of stone powder. Furthermore, three-layer feed-forward artificial neural network (3FFNN) was used to estimate and verify the accuracy of the thermal conductivity coefficient of PET nonwovens coated with white tuff, perlite, and volcanic stone powder. The results showed that perlite stone powder provided higher thermal insulation compared to white tuff and volcanic stone powder. Moreover, thermal insulation coefficient of samples increased with the rise in concentration of white tuff, perlite, and volcanic stone powder. Besides, the accuracy of 3FFNN was 99 %. Artificial neural network (ANN)-based results showed that the thermal conductivity coefficients of samples with four different concentrations obtained from white tuff, perlite, and volcanic stone powder were almost the same for experimental and ANN-trained models. According to the results, it was seen that 3FFNN was correctly modeled, and the prediction of the thermal conductivity coefficients was successfully realized.
Influence of Shear Lip Symmetry on the Fracture Behavior of Charpy Specimens
Authors: Lucon Enrico
Published: January 2019

An investigation was conducted at the National Institute of Standards and Technology (NIST) on the influence of shear lip symmetry on the fracture behavior (absorbed energy and data scatter) of Charpy specimens at different energy levels, corresponding to NIST low-energy, high-energy, and super-high-energy certified verification specimens. Whenever both shear lips are on the same tested specimen half (symmetrical fracture), absorbed energy tends to be lower than when each specimen half includes one shear lip (asymmetrical fracture). Fracture type does not have a significant effect on impact toughness or variability at low- or high-energy levels, but its influence becomes significant above 200 J. Specifically, super-high-energy specimen lots do not fulfill the NIST requirement (sample size < 5.0) when both fracture types are combined, whereas they may become acceptable if only symmetrical or asymmetrical fractures are considered. This tendency is particularly clear for the 9310 (3-nickel) steel, which is currently under consideration for the reinstatement of super-high-energy specimens in the NIST Standard Reference Materials catalog. The most effective method for preventing the formation of shear lips, and therefore avoiding this type of bimodal behavior, is to side-groove the Charpy specimens for a total thickness reduction of 10 %.
Sylvie Vartan – 50 ans de bonheur? Stationen in der Karriere eines yé-yé-Idols
Authors: Bonnermeier Andreas
Published: January 2019

About 50 years ago, Sylvie Vartan was one of the major stars of the French chanson yé-yé. Being the perfect example of promulgation through the mass media, she quickly received the status of an idol and became one of the favorite copains of French adolescents in the 1960s. As one of the few real stars of the yé-yé movement, she managed to continue her career up to the present day: first by adopting the American show model, then by engaging in projects with new authors and representatives of the new French chanson. Success was not always part of the show, but Vartan found a way to conserve parts of her public even in the new millennium. Is this the reason why she can be considered an idol unaffected by time?
Musik – Sprache – (Sprach-)Bild. Zur Semiotizität italienischer barocker Gleichnisarien (2. Teil)
Authors: Agnetta Marco
Published: January 2019

The aim of the present study is to describe some of the possible relations between music, language and verbal picture (or metaphor) which are given in the drammi per musica of the early 18th century and, especially, in four allegorical arias in Vivaldi’s opus La Griselda (1735). This paper sketches some aspects of the cooperation between librettist (Goldoni) and composer (Vivaldi) as well as the importance of metaphor for the interlinkage of music and language in such arias. The essay is divided up into two parts: the first part, which has been presented in ATeM 2 (2017), outlines the bipartite textual structure of the mentioned simile arias (metaphoric vs. literal stanza) which recalls the same two-piece structure of renaissance and baroque emblems. The second part which is presented in the following will focus on the interaction of poetic language, verbal image and Vivaldi’s music in the mentioned simile arias. Here it is explained why questions on musical semantics primarily require a theory of the sign occurrence before generalizations can be carried out on the level of sign systems. The contribution also sheds light on the central role of internal sign learning processes that may transcend arias, entire operas and other combined artworks.

Cognitive decline with aging is often due to altered levels of protein expression. The NMDA receptor (NMDAR) and the complex of proteins surrounding the receptor are susceptible to age-related changes in expression. In the frontal cortex of aged mice, there is a significant loss of expression of the GluN2B subunit of the NMDAR, an increase in Fyn expression, and no change in PSD-95. Studies have also found that, in the frontal cortex, phosphorylation of GluN2B subunits and palmitoylation of GluN2 subunits and NMDAR complex proteins are affected by age. In this study, we examined some of the factors that may lead to the differences in the palmitoylation levels of NMDAR complex proteins in the frontal cortex of aged animals. The Morris water maze was used to test spatial learning in 3- and 24-month-old mice. The acyl–biotinyl exchange method was used to precipitate palmitoylated proteins from the frontal cortices and hippocampi of the mice. Additionally, brain lysates from old and young mice were probed for the expression of fatty acid transporter proteins. An age-related increase of palmitoylated GluN2A, GluN2B, Fyn, PSD-95, and APT1 (acyl protein thioesterase 1) in the frontal cortex was associated with poorer reference memory and/or executive functions. These data suggest that there may be a perturbation in the palmitoylation cycle in the frontal cortex of aged mice that contributes to age-related cognitive declines.
Stress Elicits Contrasting Effects on the Structure and Number of Astrocytes in the Amygdala versus Hippocampus

Stress causes divergent patterns of structural and physiological plasticity in the hippocampus versus amygdala. However, a majority of earlier studies focused primarily on neurons. Despite growing evidence for the importance of glia in health and disease, relatively little is known about how stress affects astrocytes. Further, previous work focused on hippocampal astrocytes. Hence, we examined the impact of chronic immobilization stress (2 h/d, 10 d), on the number and structure of astrocytes in the rat hippocampus and amygdala. We observed a reduction in the number of glial fibrillary acidic protein (GFAP)-positive astrocytes in the basal amygdala (BA), 1 d after the end of 10 d of chronic stress. Detailed morphometric analysis of individual dye-filled astrocytes also revealed a decrease in the neuropil volume occupied by these astrocytes in the BA, alongside a reduction in the volume fraction of fine astrocytic protrusions rather than larger dendrite-like processes. By contrast, the same chronic stress had no effect on the number or morphology of astrocytes in hippocampal area CA3. We also confirmed previous reports that chronic stress triggers dendritic hypertrophy in dye-filled BA principal neurons that were located adjacent to astrocytes that had undergone atrophy. Thus, building on earlier evidence for contrasting patterns of stress-induced plasticity in neurons across brain areas, our findings offer new evidence that the same stress can also elicit divergent morphological effects in astrocytes in the hippocampus versus the amygdala.
