Políticas do esquecimento: trauma e fantasmagoria nas culturas brasileira e portuguesa
Authors: Vasconcellos Lisa Carvalho 
Published: June 2019

A escassa produção de textos – literários ou não – sobre a Colônia Correcional da Ilha Grande, no Brasil, e o campo de prisioneiros de Tarrafal, na África portuguesa, dois importantes centros de detenção política, pode ser tomada como um índice das dificuldades enfrentadas pelas culturas desses países na elaboração das práticas autoritárias às quais ambos foram submetidos ao longo de quase todo o século XX. Escritos sob o influxo da dor e do trauma, mas também do interdito e do recalque (cf. FREUD, 2010), muitos dos testemunhos, dos depoimentos e dos textos ficcionais (memorialísticos e autobiográficos em sua maioria) que procuraram pensar tais assuntos estão marcados pelo silenciamento de conflitos e pela denegação – novamente em sentido freudiano – da violência experienciada. Nesse sentido – e conforme propõem Roberto Vecchi e Margarida Calafate Ribeiro (cf. RIBEIRO & VECCHI, 2011) no que diz respeito à memória poética da Guerra Colonial lusa – os conceitos de fantasmagoria, rastro e resto propostos por Walter Benjamin podem funcionar como provocação teórica para o entendimento dos textos literários e da cultura letrada desses países (assim como das práticas políticas que lhe servem de horizonte). No trabalho que ora propomos, o objetivo será estudar comparativamente os livros Memórias do cárcere (1953), de Graciliano Ramos e Tarrafal, o pântano da morte, de Cândido de Oliveira, procurando ver como ambas as obras – ao mesmo tempo em que se reconhecem assombradas pelos fantasmas do silenciamento e da repressão – decidem enfrentá-los, usando o próprio texto como arma e mediação.
O autoritarismo e a violência em O rei branco, de György Dragomán
Authors: Lazzaretti Jildonei , Martins Adriana Claudia 
Published: June 2019

Este artigo consiste em uma análise da obra O rei branco, de György Dragomán, a partir dos conceitos de autoritarismo e de violência, a fim de constatar como a narrativa se desenvolve em relação a essas duas temáticas. Nesse sentido, são consideradas as definições de “autoritarismo” e “violência” presentes no Dicionário de Política, de Bobbio el al. (1998), bem como a reflexão teórica e alegórica de Wolfgang Sofsky no Tratado sobre la violencia (2006). Além disso, são também analisadas as referências históricas utilizadas na construção ficcional da narrativa, a fim de compreender as especificidades do regime autoritário e violento mencionado na obra. Desta forma, a presente análise demonstra a centralidade dos conceitos de autoritarismo e de violência em O rei branco, sendo determinantes, não apenas para o desenvolvimento do enredo, como também para a transformação do narrador-personagem: Dzsátá.
Agression en milieu psychiatrique fermé : identification des déclencheurs qui précèdent les agressions contre les intervenants
Authors: Groleau Robert , Da Silva Guerreiro Joao 
Published: June 2019

Cette étude vise l’identification des déclencheurs qui précèdent les agressions survenues dans un hôpital psychiatrique fermé. Une analyse de contenu de 140 rapports d’incident visant l’identification du déclencheur qui précédait immédiatement les événements d’agression survenus entre 2012 et 2017 a été effectuée. Avec un accord interjuge de 0,87, les résultats concordent avec ceux retrouvés dans des études précédentes. Plus de 37 % des agressions surviennent à la suite d’une intervention verbale d’un intervenant, alors qu’un peu plus de 54 % ont lieu à la suite d’un contact physique entre un intervenant et un patient. Moins de 9 % des agressions subies par le personnel sont liées à des événements où il a été impossible d’observer un déclencheur. Ces résultats sont discutés dans le cadre d’une approche interactionnelle sur l’agression en psychiatrie légale et ils permettent de proposer des pistes pour réduire le risque d’agression.
Relative and absolute within-session reliability of the modified Star Excursion Balance Test in healthy elite athletes
Authors: Onofrei Roxana R. , Amaricai Elena , Petroman Radu , Suciu Oana 
Published: June 2019

Background
The Star Excursion Balance Test (SEBT) is commonly used to assess dynamic postural balance both in clinical practice and research. The aim of our study was to assess the within-session relative and absolute reliability of participants’ performance of the modified SEBT (mSEBT) using a single practice trial in healthy elite athletes who were familiar with the test.

Methods
An intra-session repeated-measures design was used to investigate the relative and absolute reliability of participants’ (healthy athletes partaking in sports at a high-risk of ankle sprain injury) performance of the mSEBT. A total of 122 healthy elite athletes from soccer (n = 73), basketball (n = 15), and volleyball (n = 34) performed one practice trial and three test trials within one session, in three directions (anterior, postero-medial, and postero-lateral), for both legs. Intraclass correlation coefficient (ICC), standard error of measurement (SEM), and smallest detectable change at a 95% confidence were calculated.

Results
We found a good to excellent relative within-session intra-rater reliability between the three trials on specified directions, with an ICC (3,1) from 0.90 to 0.95. SEM and SDC95 for normalized and composite scores, for both legs ranged from 0.91 to 2.86, and 2.54 to 7.94, respectively.

Conclusions
In conclusion, we report good to excellent within-session reliability for the mSEBT. Our results confirm that the test can be reliably used with only one practice trial in healthy elite athletes familiar with the test.
Bioinformatic pipelines for whole transcriptome sequencing data exploitation in leukemia patients with complex structural variants
Authors: Hynst Jakub , Plevova Karla , Radova Lenka , Bystry Vojtech , Pal Karol , Pospisilova Sarka 
Published: June 2019

Background
Extensive genome rearrangements, known as chromothripsis, have been recently identified in several cancer types. Chromothripsis leads to complex structural variants (cSVs) causing aberrant gene expression and the formation of de novo fusion genes, which can trigger cancer development, or worsen its clinical course. The functional impact of cSVs can be studied at the RNA level using whole transcriptome sequencing (total RNA-Seq). It represents a powerful tool for discovering, profiling, and quantifying changes of gene expression in the overall genomic context. However, bioinformatic analysis of transcriptomic data, especially in cases with cSVs, is a complex and challenging task, and the development of proper bioinformatic tools for transcriptome studies is necessary.

Methods
We designed a bioinformatic workflow for the analysis of total RNA-Seq data consisting of two separate parts (pipelines): The first pipeline incorporates a statistical solution for differential gene expression analysis in a biologically heterogeneous sample set. We utilized results from transcriptomic arrays which were carried out in parallel to increase the precision of the analysis. The second pipeline is used for the identification of de novo fusion genes. Special attention was given to the filtering of false positives (FPs), which was achieved through consensus fusion calling with several fusion gene callers. We applied the workflow to the data obtained from ten patients with chronic lymphocytic leukemia (CLL) to describe the consequences of their cSVs in detail. The fusion genes identified by our pipeline were correlated with genomic break-points detected by genomic arrays.

Results
We set up a novel solution for differential gene expression analysis of individual samples and de novo fusion gene detection from total RNA-Seq data. The results of the differential gene expression analysis were concordant with results obtained by transcriptomic arrays, which demonstrates the analytical capabilities of our method. We also showed that the consensus fusion gene detection approach was able to identify true positives (TPs) efficiently. Detected coordinates of fusion gene junctions were in concordance with genomic breakpoints assessed using genomic arrays.

Discussion
Byapplying our methods to real clinical samples, we proved that our approach for total RNA-Seq data analysis generates results consistent with other genomic analytical techniques. The data obtained by our analyses provided clues for the study of the biological consequences of cSVs with far-reaching implications for clinical outcome and management of cancer patients. The bioinformatic workflow is also widely applicable for addressing other research questions in different contexts, for which transcriptomic data are generated.
WAVE FORCE ON A VESSEL TIED AT OFFSHORE DOLPHINS
Authors: Goda Yoshimi , Yoshimura Tomotsuka 
Published: June 2019

The solution of wave scattering by a vertical elliptical cylinder is
applied to calculate the wave forces exerted upon it. The wave forces in
the directions of long and short axes of ellipsis are shown in nondimensional
forms as the functions of the angle of wave approach, the diameter-to-wavelength
ratio, and the aspect ratio of ellipsis. The results of wave force computed
are also shown in terms of the virtual mass coefficients associated with the
reference volume of the circular cylinder the diameter of which is approximately
equal to the apparent width of the elliptical cylinder observed from the direction
of wave approach.
Theory is further applied for the wave forces acting upon a vessel moored
tight at offshore dolphins and the forces transmitted to the dolphins through
the vessel. The vessel is approximated with the fixed elliptical cylinder
having the same width-to-length ratio. The computation with directional wave
spectra shows that a tanker of 200,000 D.W.T. may exert the force of about
1,400 tons at the one-third maximum amplitude to each breasting dolphin when
the tanker is exposed to the incident waves of H,/,,=1.0m and T» / =10 sec from
the broadside.
COAST PROTECTION AGAINST THE ACTION OF WAVES AND CURRENTS
Authors: Mikhailov Leren P. , Uspenskii Sergei M. 
Published: June 2019

According to the information available in the USSR,
now in the world there are more than 13000 reservoirs with storage capacity over 1 million m? in service and under construction. The largest ones are illustrated in Table 1. In some countries these storage reservoirs constitute rather a great per cent relative to all the reservoirs of the given country. (Table 2). Lately, such reservoirs have substantially grown in number in many countries of the world, especially in the USSR and USA, what is seen from the chart (Fig.1). In this connection, one can conclude on the great area of some reservoirs (reaching sometimes thousands of square kilometers), on their importance in the balance of the controlled runoff, making up in some countries over 95 per cent and on the intensive increase of their storage capacity beginning from the fifties of the present century. The above said is one of the reasons of greater interest in the action of waves and currents of the shore line showing up most intensively on the largest storage reservoirs. The length of the shore line of the USSR reservoirs is over 40000 km. The length of the erosion shores of storage reservoirs at the hydroelectric projects on the Volga and Dnieper River make up more than 30 per cent of the total shoreline of these reservoirs, while that of the reservoirs on the Kama River - 35 per cent. Most intensively the erosion is going on in the first decades of the operation of the reservoirs. The action of waves on the shore results in formation of the underwater slope with a gradient at which the wave energy is dissipated on the shoal, and the shore erosion slows gradually down until it ceases completely. However, it is rather difficult now to determine the period of the shore formation attenuation process in view of the fact that the problem of distribution of wave energy between all the phenomena taking place here is not properly studied yet and it is hot also clear what width and gradient of the shoal can fully baffle the wave energy and how much time it will take for such a shoal to get formed. The observation carried out on the natural water bodies well prove it.
FIELD OBSERVATION ON SUSPENDED-LOAD IN THE SURF ZONE
Authors: Katoh Kazumasa , Tanaka Norio , Irie Isao 
Published: June 2019

Both the concentration of suspended-load and the
current velocity have been measured continuously in
the surf zone. In order to measure the concentration
of the suspended-load in the surf zone, a optical
densitometer has been developed. The current
velocity was measured by means of electromagnetic
current meters. According to data analyses, the
mean concentration of the suspended-load is high in
the final breaking zone and in the breaker zone. In
the final breaking zone, the concentration
fluctuates with the period of the incident waves.
On the other hand, it fluctuates with the period
longer than 40 seconds in the breaker zone and it
becomes high when the current is offshoreward. The
directions of the net transport of the suspendedload
in the middle layer in and near the surf zone
are offshoreward.

Carbon Black
Authors: Niedermeier Werner , Chavez Ricardo , Westenberg Hauke , Schinkel Arndt‐Peter 
Published: November 2024

Abstract
Carbon black is a high‐tech raw material, with clearly defined properties, widely used in different fields of applications, as an excellent black pigment, reinforcing particle in polymers, UV‐protection agent as well as conductive material in batteries.
Due to its excellent pigmentation properties, especially its light stability and universal insolubility, carbon black has been used as a black pigment since early times. Today you can find it in car coatings, black dashboards, and inks.
Carbon black is also used as reinforcing particle to modify the mechanical and electrical properties of elastomers and plastics. Its largest application is in tires to improve durability, abrasion resistance, and traction.
The individual morphology parameters of the carbon black are tailored for each application. These parameters as well as the microstructure are discussed after the introduction in the second section. The following section deals with the methods to characterize the morphology and to carefully control the formation process. The following two sections focus on the formation and various production processes. Section 6 is devoted to the applications of carbon blacks in plastics and elastomers as a pigment as well as a reinforcing particle. The subject of achieving optimal quality dispersion and its importance to end‐use performance is also addressed. Finally, the topics of sustainability and product safety are outlined.
Determining oviposition preferences to inform population reinforcement of the specialist chequered blue butterfly (Scolitantides orion)
Authors: Dunskis Aivars , Stigenberg Julia , Ågren Jon , Sletvold Nina 
Published: November 2024

Abstract

Many Lepidoptera species are declining to the point that active measures such as reinforcements and reintroductions are necessary to maintain viable populations. To maximise success of such efforts, we need to understand the factors influencing habitat preferences for oviposition.

In a Swedish island population of the red‐listed chequered blue butterfly (Scolitantides orion), we characterised oviposition preference by documenting whether the presence and abundance of eggs (i) increased with size and local density of its host plant, orpine (Hylotelephium telephium), and (ii) was associated with nectar plant abundance, degree of shading, and ground cover composition within small and large circular plots (1 m vs. 5 m radius) around focal plants. To reinforce a tiny population on a neighbouring island, we released 127 pupae and 46 imagos and recorded oviposition for two seasons.

The probability of receiving eggs increased with focal host plant size, and also with mean size of other host plants and cover of lichens within the large plots. The abundance of eggs within large plots increased with host plant density and amount of lichen cover. Habitat characteristics of the large plots predicted oviposition better than did those of small plots, and both outperformed models including host plant size only.

In the reinforcement population, all released pupae eclosed, and we found a total of 507 eggs on 272 host plants during the release season. Eggs were present on 5% of examined host plants, and median distance to a release spot was 19.3 m. In the following year, we found 420 eggs on 209 plants, and median distance to a release spot increased to 35.7 m, indicating diffusion through the habitat.

Practical implication. The chequered blue butterfly prefers to oviposit on large host plants in patches with high host density and high cover of lichens. To identify suitable release habitats, environmental conditions should be considered in an area of ca 80 m2. The reinforcement shows that small releases can be successful and suggests that similar low‐effort approaches can be effective to boost local populations of many threatened butterflies, provided suitable habitats are available.
