Authors: Dębski Przemysław , Białas Ewelina , Gnat Rafał
Published: February 2019

Self-myofascial release (SMR) is a well-known and popular therapy. Its growing popularity is based on high effectiveness and availability. However, there is a lack of agreement about which parameters should be used to optimize the effects of the therapy. The purpose of this review is to critically select and assess current literature and ascertain the values of the follow­ing parameters: (1) therapy duration, (2) volume of applied pressure, (3) speed and (4) frequency of roll, (5) type of roller, (6) the number of treatment applications during one session, (7) the duration of intervals between applications that yield the best results in terms of soft tissue.

The authors launched their research in May 2018. The search strategy included the electronic databases EBSCOhost and PubMed. The following inclusion criteria were assessed:

- English language, high quality manuscripts (evaluation in PEDro scale)

- at least one of the groups using the foam roller, tennis ball or the stick to fascial release

- basic parameters of therapy described.A total 55 articles met the inclusion criteria. Patients can usually withstand a maximum tolerable pressure for 30-120 seconds, repeated 1-3 times, separated by 30 seconds of rest. The intensity of a single rolling movement should be moderate, and the movement should last about 3 seconds. Keeping the roller on particularly sensitive areas is recommended to release tension and enhance blood perfusion.Currently, there is no consensus on an optimal FR programme. However, there is a tendency to use SMR tools with a physiol­ogy-based method to enhance therapeutic efficiency.

Study aim: To verify the relationship between different durations of regular practice of physical activity in aspects related to the anthropometric profile and hepatic function of patients infected by hepatitis C virus (HCV). Material and methods: 125 patients (aged 55.2 ± 10.4 years) participated in the study. Clinical data were obtained through medical records available at the Pernambuco Liver Institute. Physical activity levels were obtained through the International Physical Activity Questionnaire (IPAQ) short form to classify the patients according to the guidelines of the American College of Sports Medicine (ACSM). Results: Significant differences were found in GGT 141 (28-378 U/L) and HDL 39 (27-56 mg/dL) respectively in insuffi­ciently active and physically active groups, AST 71 (26-268 U/L), ALT 83 (36-452 U/L), GGT 78 (3-532 U/L), alkaline phos­phatase 74 (47-302 mg/dL) and total bilirubin 0.7 (0.1-2.8 mg/dL) in insufficiently active and very physically active groups. Anthropometric data showed significant differences in chest (p < 0.01), abdomen (p < 0.02) and waist measurement (p < 0.01) between insufficiently active and very physically active groups.

Conclusion: Physical activity, when practiced regularly for more than 300 minutes per week, can improve the clinical and an­thropometric profile in patients infected with HCV.
An inversion method based on random sampling for real-time MEG neuroimaging
Authors: Pascarella Annalisa , Pitolli Francesca
Published: February 2019

The MagnetoEncephaloGraphy (MEG) has gained great interest in neurorehabilitation training due to its high temporal resolution. The challenge is to localize the active regions of the brain in a fast and accurate way. In this paper we use an inversion method based on random spatial sampling to solve the real-time MEG inverse problem. Several numerical tests on synthetic but realistic data show that the method takes just a few hundredths of a second on a laptop to produce an accurate map of the electric activity inside the brain. Moreover, it requires very little memory storage. For these reasons the random sampling method is particularly attractive in real-time MEG applications.
Extension of tumor fingers: A comparison between an individual-cell based model and a measure theoretic approach
Authors: Scianna Marco , Colombi Annachiara
Published: February 2019

The invasive capability is fundamental in determining the malignancy of a solid tumor. In particular, tumor invasion fronts are characterized by different morphologies, which result both from cell-based processes (such as cell elasticity, adhesive properties and motility) and from subcellular molecular dynamics (such as growth factor internalization, ECM protein digestion and MMP secretion). Of particular relevance is the development of tumors with unstable fingered morphologies: they are in fact more aggressive and hard to be treated than smoother ones as, even if their invasive depth is limited, they are difficult to be surgically removed. The phenomenon of malignant fingering has been reproduced with several mathematical approaches. In this respect, we here present a qualitative comparison between the results obtained by an individual cell-based model (an extended version of the cellular Potts model) and by a measure-based theoretic method. In particular, we show that in both cases a fundamental role in finger extension is played by intercellular adhesive forces and taxis-like migration.

Authors: Filipiak Beata Zofia , Dylewski Marek , Cheba Katarzyna
Published: February 2019

The principle of transparency not only is changing but its importance is increasing. International organizations, including the OECD, are seeking to develop harmonized standards of transparency in public administration. This fact is of particular importance in the search for common solutions for the OECD countries in the implementation of transparency standards, but also this organisation has sought adequate methods for measuring implementation of these standards. The main purpose of the study is to analyze the level of spatial homogeneity in the area of application of the standards of “integrity” of the OECD, which are an expression of the principle of transparency in the member states of this organization, on the European continent. In the study vector calculus was used.
The Significance of Openness and Transparency for Accountability in Public Finances
Authors: Szołno-Koguc Jolanta
Published: February 2019

An essential condition for asserting responsibility in public finances is that they are open and transparent. The Public Finance Act mentions ways of applying the principles of openness, and also stipulates the entities obliged to present data and information on public finances. There is, however, no legislation connected directly with transparency. So do the general requirements of classification and of accountancy and reporting principles constitute sufficient premises for accountability and asserting responsibility? An analysis of the reports and documents concerning the Polish public finance sector indicates that the processes of collecting and spending public funds are insufficiently transparent. The information system enables formal verification of discipline of public finances; however, it does not provide a sufficient basis to assess the effectiveness and efficiency, which are of key importance in terms of accountability. The aim of the article is to analyse the requirements and standards in the field of openness and transparency insofar as these concern the responsibility and accountability of public authorities, along with elements of how these are assessed in the Polish public finance system. A normative descriptive method was applied which took into consideration elements of finance theory, as well as an analysis of practical experience in the field of how public sector bodies function in Poland. The research objectives are realised mainly on the basis of a critical review of the literature on the subject, and an analysis of legal acts, reports and other documents of domestic and international institutions. The considerations and analyzes have led to several key applications to develop the principles of openness and transparency in relation to improving the accountability of public finances.
On Atriplex canescens (Chenopodiaceae s. str./Amaranthaceae s. l.) in Tunisia: nomenclatural and morphological notes on its infraspecific variability
Authors: Iamonico Duilio , Mokni Ridha El
Published: February 2019

Populations of Atriplex canescens var. gigantea were found in Lamta, Bouficha-Enfidha (central Tunisia), and Medenine (southern Tunisia). Literature data concerning the presence of this species in Tunisia are contradictory but now our data confirm its occurrence in the country. On the other hand, this variety is reported in the present paper for the first time both in Tunisia and in North Africa in general. Morphological characters and ecological data are presented, as well as notes about patterns of infraspecific variability of A. canescens. Nomenclatural notes on infraspecific names in A. canescens, as well as on the closely related species A. garrettii, are provided. The types of the names A. canescens var. laciniata, A. canescens var. macilenta, A. garrettii, Obione occidentalis var. angustifolia, and Pterochiton occidentale, that in earlier publications were erroneously considered to be holotypes, are in fact lectotypes (for most of taxa) under Art. 9.10 of the ICN. Isolectotypes were found at CAS (A. canescens var. laciniata and A. canescens var. macilenta), GH (A. canescens var. macilenta), and YU (Atriplex nuttallii).

Authors: Zabihi-Samani Masoud , Mokhtari Seyed Payam , Raji Farzaneh
Published: February 2019

Cement is a common and widespread building material over the world. Similarly, carbon dioxide emissions have been significantly increased due to cement production. Alternative low-carbon binders rather than cement have been progressively sought in recent years. Fly ash was found as an available option, since it is being largely disposed annually as a waste material. In this research several studies have been reviewed and recent applications of fly ash on concrete specification, including strength and fracture toughness of green concrete have been perused. Furthermore, transport properties of high volume fly ash after exposure to high temperature and influence of curing temperature on strength development of fly ash-recycled concrete aggregate blends have been investigated. The investigated test results showed that the properties of composites incorporating fly ash depend on the age of the concrete. Test results also revealed that transport properties of concrete increased notably after exposure to 400cº and the results achieved on fly ash-recycled concrete aggregate led to the conclusion that 15% FA is the optimum blend for road stabilization applications.
Comparative Analysis of Structure-From-Motion Software’s –An Example of Letychiv (Ukraine) Castle and Convent Buildings
Authors: Lewińska P. , Pargieła K.
Published: February 2019

Letychiv (pl. Latyczów) is a town located in central Ukraine in the Khmelnytskyi Oblast. It has a unique and complicated history. Second World War left it in ruin, destroying buildings, infrastructure and decimating its once large population. Perhaps the most prominent part of the town currently is the building Dominican convent with adjoin Letychiv Assumption Church. This object is surrounded by what is left of the previously impressive Letychiv Castle, founded by Jan Potocki in 1598. Past 30 years have been dedicated by this small Catholic parish towards rebuilding monastery-castle-church complex. Since this is an ongoing project, it was decided to perform a photographic inventory of the current state of the construction and to create a 3D digital model of the castle, facade of the church and monastery, and the altar. This task have proven to be difficult due to complicated structure of the object. Facades and inner parts of the church are almost white with limited number of distinctive elements, painted in pail gold. Elements other than white are almost identical to each other. It leads to various errors in the processing of Structure-from-motion. This article describes how various versions of SfM algorithm work thru mention difficulties, compares results in terms of accuracy, level of detail and overall look. It also describes how SfM can help to document various stages of restoration of important historical objects.
Forests in the Czech Public Discourse
Authors: Stachová Jana
Published: February 2019

Forests are being increasingly studied within the framework of social sciences, especially in relation to environmental problems and global climate change. This article deals with the perception of Czech forests and their management at two basic levels: at the level of sociological analysis of in-depth interviews with experts in the field of forestry and at the level of public opinion research. The main aim of this study was to describe the attitudes of professionals and the general public towards forests and forestry, especially with regard to climate change. Qualitative analysis of interviews with professionals discerned two main categories of opinion: ecological realism and social constructionism. The results of the study show that the Czech public, in agreement with ecological realists, considers it highly important to preserve and support the non-productive environmental functions of forests. The public also prefers close-to-nature forest management practices. Czech Republic is witnessing a fundamental shift in the mindset about forests. Although the public still expects forests to retain their production function, it perceives their environmental functions as increasingly important.
John Murray and James B. Torrance on Covenant Theology
Authors: Moga Dinu
Published: February 2019

Whatever opinion we might have on the covenants of God with man, we cannot escape the fundamental truth that covenant theology is the best way of presenting the Biblical development of God’s revelation in the history of mankind. Therefore, our duty is to learn to think in covenantal terms, because thinking in covenantal terms means to think biblically. When God, in His sovereignty, has chosen to deal with man, He has chosen to do so through two covenants: the covenant of works, made between God and Adam as the representative head of all mankind, and through the covenant of grace, made between God and Christ on behalf of those who were predestined and elected in Christ.

Colonisation of gastrointestinal tract by extended spectrum beta lactamase (ESBL)-producing Gram-negative bacteria is a source for infections. The present work is a prospective study in Latvia aimed to determine the role of two surgical profile wards in transmission of ESBL-producing bacteria. Differences between hospital wards were not analysed due to low number of patients. We have also determined a correlation between the duration of hospitalisation and risk of ESBL colonisation. Tests for ESBL-producing bacteria were made twice for 136 patients — upon admission and upon discharge from the hospital. Of them, 21 (15.4%) patients already were ESBL-positive at the time of admission and 115 (84.6%) patients were ESBL-negative. Upon discharge from hospital, 45 (33.1%) patients were ESBL-positive, one patient was ESBL-negative, and 25 (18.4%) of ESBL-positive cases had emerged during hospitalisation. In total, 46 (33.8%) from 136 patients were ESBL-positive and ESBL was positive in 51 bacterial isolates. On discharge from hospital, the newly acquired ESBL-positive bacterial isolates were K. pneumoniae (n = 18), E. coli (n = 7) and P. mirabilis (n = 3). The prevalence of ESBL-positive E. coli from all detected E. coli was 7.0% and from all Klebsiella spp. — 88.9% in gut flora. Analysis of patientassociated wound infections did not show correlation between the ESBL-producing gut microbiota and the bacterial species involved in wound infection.
The bilingualism wars: Is the bilingual advantage out of (executive) control?
Authors: Fernández-López María , Perea Manuel
Published: February 2019

Whether bilingualism has an effect on the executive function of non-verbal representations is probably one of the most controversial issues in cognitive psychology and cognitive neuroscience. As bilinguals have to alternate between two languages that compete for selection in their daily lives, they make use of selection, inhibition, and monitoring (i.e., components of executive function) more often than monolinguals. Thus, it would not be surprising that these highly trained abilities at selecting and monitoring the linguistic processes would also help the processing of non-linguistic representations. Although the “bilingual advantage” in executive control (Bialystok, 1999) has been repeatedly demonstrated, a number of recent studies—in particular since the publication of the Paap and Greenberg (2013) study—have questioned this effect. Both positive and null findings are currently being published from each of the two sides, thus making it difficult to reach consensus in the scientific community. Here, we propose a plausible solution to this debate: a group of independent researches should carry out a carefully planned large-scale study.

Melanonychia refers to a brown or black coloration of the nail plate caused by numerous factors. Regarding the arrangement of pigmentation, we can differentiate between total melanonychia, when pigmentation involves the whole nail plate, or transverse or longitudinal melanonychia, when pigmentation involves the nail in a form of transverse or longitudinal band of pigmentation, respectively. Since longitudinal melanonychia can be a sign of numerous benign and malignant lesions, it often poses a diagnostic challenge for a dermatologist. Herein, we report a case of a 13-year-old girl who developed longitudinal melanonychia on multiple nails after receiving a therapy with azithromycin.

Published: February 2019

The article deals with the problem of electric power production in terms of environmental impact, in particular the energy efficiency of its production to utilize primary sources. The efficiency of its production directly depends on the composition of primary sources and technologies used. Difference in efficiency by converting various forms of energy into electrical power and their ratio in the use directly affect the resulting efficiency, production of emissions and thus the environmental impact. Electric traction, its production, is burdened less efficient than other types of tractions used in transport, but at the final reconciliation of their consumption in vehicles, this difference decreases or delays because the vehicles themselves work with different conversion efficiency of its traction on mechanical work, vehicle driving.
Analysis of Liquid Flow and Mixing in an Oscillatory Flow Reactor Provided with 2D Smooth Periodic Constrictions
Authors: Almeida F. , Rocha F. , Ferreira A.
Published: February 2019

In this research paper the residence time distribution (RTD) was monitored for a range of fluid oscillation, frequency, amplitude and flow rate in two oscillatory flow reactors (OFR) provided with 2D smooth periodic constrictions (2D-SPC) with different designs. It was studied the axial liquid dispersion using axial dispersion model and the mixing efficiency using tank-in-series model for continuous mode. Two cases, with and without fluid oscillation, were studied and determined the optimum conditions to ensure a close plug flow, an efficient mixing and a low axial liquid dispersion. The optimum operation conditions for the two 2D-SPC designs were found. Moreover, the effect of open cross-sectional area (a) on mixing and axial dispersion was also investigated. For low cross-sectional area values the mixing is higher. It was observed that fluid oscillation increases the mixing intensity even at lower flow rates, and the axial dispersion increases as the flow rate increases.

Published: February 2019

Near the end of the 1950s, a new key artistic institution was created in Argentina — The National Endowment for the Arts. Its primary function was to centralize and administrate all public funds granted to the promotion of art and culture. What was new about it was that it was able to create financial programs in order to fulfill its objectives, thus making the FNA the first national bank for the arts. In this paper we will study the impact that this institution had on the Argentinian art world, its market, and the hierarchies within.

Authors: TASDEMİR Sakir , OZKAN İlker Ali
Published: February 2019

Computer technology and software are widely used in every multi-discipline field. Geomatics engineering can be seen as a pioneer of these disciplines especially in photogrammetry and image processing. Photogrammetry is a method where geometric parameters of objects on digitally captured images are determined and make measurements on them. Capturing the digital images and photogrammetric processing include several fully defined stages, which allows to generate three-dimension or two-dimension digital models of the body as an end product. The aim of this study is to predict Holstein cows’ live weight via artificial neural network whose body dimensions were determined with photogrammetry method. The body dimensions to be used in this study are obtained metric from analysis of cows’ images captured by synchronized three-dimension camera environment from different aspects. Wither height, hip height, body length, hip width of cows determined with photogrammetry. Artificial neural network prediction model was developed by using these body measurements. Dataset is divided into two after preprocessing as training and testing dataset. Different structured artificial neural network models are generated and the artificial neural network model which has the best performance is determined. Then with this artificial neural network model live weight of animals is estimated by using measurements obtained from images. After comparison of estimated live weights and weights obtained from scale, correlation coefficient is found (R=0.995). The statistical analysis shows that both groups are meaningful and artificial neural network can be used in live weight prediction safely.

Glutathione (GSH) is one of the most important thiol-containing antioxidants involved into various biochemical processes in the human body. Glutathione determination in biological fluids (saliva, urine, serum) and pharmaceutical preparations is rather important for clinical practice. Various analytical methods — spectrophotometry, fluorimetry, high-performance liquid chromatography, NMR spectroscopy, capillary electrophoresis and electrochemical methods — are widely used for this purpose. Electrochemical methods are characterized by easy implementation, low cost and possibility of miniaturization. The electrochemical behavior of reduced (GSH) and oxidized (GSSG) glutathione on a gold-carbon-containing electrode (AuCE) was studied using cathodic voltammetry with different methods of removing oxygen from an electrochemical cell: nitrogen sparging and addition of sodium sulfite (4 mol/dm3). It has been shown that traces of H2O2 that remain in the near-electrode layer on the AuCE even after oxygen removal influence the electrochemical properties of GSH at a cathode sweep of the potential from 0 to –1.8 V: GSH is oxidized by H2O2 to GSSG, the most important product of this reaction is O2. An indirect determination of GSH by the current of oxygen reduction in the Na2SO3 medium in the concentration range from 0.5 × 10–8 to 4.2 × 10–8 mol/dm3 with a detection limit of 2.5 × 10–9 mol/dm3 is proposed. The developed voltammetric method is approved for the determination of GSH in certain pharmaceutical preparations.
On optimization methods in the problems of experiment design
Authors: Ermakov S. M. , Semenchikov D. N.
Published: February 2019

A new known modification for simulation of annealing to search the global extremum of the functions of many variables uses the fact that the function whenn→ ¥ converges to the δ-function concentrated at the point of global maximum off(x). The case when the function has many equal extrema is discussed in detail. Problems of this type are often present, particularly in the design of regression experiments. Here we introduce the reader to an extremum search method that is effective in solving a wide range of applied problems, and also illustrate the use of the method in some of the simplest problems of designing the regression experiments. The proposed modification of simulated annealing uses quasi-random search at the intermediate stages. This is not the most rapid, but very reliable method which provide a complete exploring of the function domain. When solving numerical examples, the so-called exactD-optimal designs are constructed, which are very difficult to be obtained by other methods. Although with the increase in the number of variables, the complexity of the method (as well as the complexity of other well-known methods) increases dramatically due to an increase in the order of the determinant, the proposed algorithm is simple, reliable, and easily parallelized. It is known that the gain from using optimal designs in some cases can justify any computational costs of developing those designs. Using the described technique, the reader will be able to construct (even using the laptop capacity) the optimal designs in different areas at moderate values of the parameters (for example, for quadratic regression for s variables in variables fors≤ 10).
Issues of standardization of the methods of chemical analysis in metallurgy
Authors: Karpov Yu. A. , Baranovskaya V. B.
Published: February 2019

The quality of chemical analysis is inextricably linked with such concepts as the methodology of analysis, unification, certification and standardization. In essence, a modern analysis technique is a type of software that allows quality control of the specific types of substances and materials in chemical composition. The methodology is a formalized regulatory document implemented at different levels — in the form of a certified procedure, in the form of an enterprise standard method, in the form of a unified industrial method, in the form of a national (state) and international standard. It is through the use of analysis techniques provides consumers, product manufacturers, and scientists with the most important information about the composition of a huge variety of substances and materials, the reliability of which allows their specific use and determines the cost of production. Therefore, the development and application of the methods need legal regulation both at the national and international levels. Features of standardization of analytical methods are considered in the case study of the quality control of metallurgical products.

Published: February 2019

The main directions in the development of the spectral systems for scintillation atomic emission analysis of powdered geological samples are aimed at increase in the sensitivity, spectral resolution, and speed of the spectrum analyzers to reduce the detection limits. The goal of the study is developing of high-speed MAÉS analyzers with hybrid assemblies of the arrays of 14 multichannel photodetectors of two types: high-sensitivity BLPP-2000 and BLPP-4000 photodetector array with high spatial resolution and theoretical estimation of the signal-to-noise ratio when recording scintillation and integral spectra with aforementioned photodetectors. The high-speed MAÉS analyzers with BLPP-2000 and BLPP-4000 photodetector arrays are designed so as to provide parallel readout of photodetectors in hybrid assemblies. They consist of 14 BLPP 2000 or BLPP 4000 photodetectors and records the spectra in the 190 – 350 nm wavelength range on a «Grand» spectrometer. The minimum exposure time is 0.9 and 1.7 msec, respectively. It is shown that in measurements of spectral-line intensities using BLPP-2000, the signal-to-noise ratio is 3 times higher in integral analysis and 5 times higher in scintillation analysis compared to measurements with BLPP-4000 photodetector array.
Optimal coding of blended seismic sources for 2D full waveform inversion in time
Authors: Flórez Katherine , Abreo Carrillo Sergio Alberto , Ramírez Silva Ana Beatriz
Published: February 2019

Full Waveform Inversion (FWI) schemes are gradually becoming more common in the oil and gas industry, as a new tool for studying complex geological zones, based on their reliability for estimating velocity models. FWI is a non-linear inversion method that iteratively estimates subsurface characteristics such as seismic velocity, starting from an initial velocity model and the preconditioned data acquired.

Blended sources have been used in marine seismic acquisitions to reduce acquisition costs, reducing the number of times that the vessel needs to cross the exploration delineation trajectory. When blended or simultaneous without previous de-blending or separation, stage data are used in the reconstruction of the velocity model with the FWI method, and the computational time is reduced. However, blended data implies overlapping single shot-gathers, producing interference that affects the result of seismic approaches, such as FWI or seismic image migration.

In this document, an encoding strategy is developed, which reduces the overlap areas within the blended data to improve the final velocity model with the FWI method.
Comparative analysis of 3D RTM Implementation Strategies for an Efficient Use of Memory in a Single GPU:
Authors: Salamanca William , Ramírez- Silva Ana Beatríz , Vivas Flor Alba
Published: February 2019

Reverse-Time Migration (RTM) is a two-way wave-equation based method used to generate images of the Earth’s subsurface. RTM has been successfully used in seismic imaging as it allows defining complex structural areas. However, RTM is a highly computational expensive algorithm that requires the computation of both the source and the receiver wavefields for each shot. Fortunately, numerical methods that compute the wave propagation using the wave equation are highly parallelizable, so they can take leverage on GPU features. However, the main problem of a GPU-RTM implementation is memory management. To take advantage of the GPU computing capabilities, the transfers to host RAM memory storage, or more expensive hard disk storage must be avoided. We present the analysis of three different strategies to implement RTM using only the memory available on a single GPU: (1) Stored wavefield checkpointing (2) Backpropagation of source wavefield using stored boundaries, and (3) Backpropagation of source wavefield using the two last snapshots and random boundaries, showing that the large amount of memory required in the first two strategies becomes a restriction over the model size.

Authors: Norris Tony , Gonzalez Jose , Parry David , Scott Richard , Dugdale Julie , Khazanchi Deepak
Published: February 2019

This paper describes the origins and progress of an international project to advance disaster eHealth (DEH) – the application of eHealth technologies to enhance the delivery of healthcare in disasters. The study to date has focused on two major themes; the role of DEH in facilitating inter-agency communication in disaster situations, and the fundamental need to promote awareness of DEH in the education of disaster managers and health professionals. The paper deals mainly with on-going research on the second of these themes, surveying the current provision of disaster medicine education, the design considerations for a DEH programme for health professionals, the key curriculum topics, and the optimal delivery mode.
Une poétique des espaces : lecture écocritique des géographies et langages hybrides dans Verre Cassé
Authors: Germain Nathan
Published: February 2019

Le roman Verre Cassé d’Alain Mabanckou présente une nouvelle réalité de l’Afrique. A travers les écrits du personnage éponyme, le lecteur entre dans la vie quotidienne d'un quartier pauvre à Pointe-Noire, au Congo. Le livre est un effort de donner une voix à cet espace normalement muet ; dans un langage qui est toujours à mi-chemin entre le français littéraire et le français populaire, Verre Cassé représente une manière de tenir compte de plusieurs espaces, tant global que local. Cet article se propose d’analyser le rôle que joue le langage dans cette ouverture aux complexités du monde et dans la mise en relation de plusieurs espaces géographiques. Verre Cassé semble nous donner un moyen d’existence « entre-deux » : entre le français littéraire et populaire, entre une prise de conscience locale et un engagement plus global. Cet article se propose donc d’examiner le rapport entre l’espace local (dans le quartier Trois-Cents) et l’espace global (le Congo, la France, ou le monde en général) dans Verre Cassé. Dans quelle mesure peut-on dire que le langage permet un enracinement et une ouverture en même temps? À partir de quelques notions géographiques de base, cet article analyse le roman de Mabanckou comme une poétique des espaces. Enfin, en examinant les théories de Glissant (Relation, Tout-monde, mondialité), l’étude explore la vision originale de l’espace que propose Mabanckou tout en démontrant la pertinence des approches écocritiques portant sur des littératures francophones.

Many variables can influence animal behavior and physiology, potentially affecting scientific study outcomes. Laboratory and husbandry procedures—including handling, cage cleaning, injections, blood collection, and animal identification—may produce a multitude of effects.
Previous studies have examined the effects of such procedures by making behavioral and physiologic measurements at specific time points; this approach can be disruptive and limits the frequency or duration of observations. Because these procedures can have both acute and long-term effects,
the behavior and physiology of animals should be monitored continuously. We performed a retrospective data analysis on the effects of 2 routine procedures, animal identification and cage changing, on motion and breathing rates of mice continuously monitored in the home cage. Animal identification,
specifically tail tattooing and ear tagging, as well as cage changing, produced distinct and reproducible postprocedural changes in spontaneous motion and breathing rate patterns. Behavioral and physiologic changes lasted approximately 2 d after tattooing or ear tagging and 2 to 4 d for cage
changing. Furthermore, cage changes showed strain-, sex-, and time-of-day–dependent responses but not age-dependent differences. Finally, by reviewing data from a rodent model of multiple sclerosis as a retrospective case study, we documented that cage changing inadvertently affected
experimental outcomes. In summary, we demonstrate how retrospective analysis of data collected continuously can provide high-throughput, meaningful, and longitudinal insights in to how animals respond to routine procedures.

ATTEMPT ON G. YE. RASPUTIN’S LIFE ON 29 JUNE, 1914 IN RESPONSES OF THE RUSSIAN PRESS (JUNE-JULY 1914)
Authors: Kotsyubinskii Daniil Aleksandrovich
Published: February 2019

The article is devoted to the analysis of the Russian press reaction to the events connected with an attempt on G. Ye. Rasputin’s life on 29 June, 1914. The conclusion is made about the priority of the political orientation of the news materials over their reliability. Unreliable details of the newspaper publications are revealed, in particular those included in historiography. The author shows that the greatest deviations from the canons of good-quality journalism were observed in the work of the newspapers oriented to the social “elites”, who were critical of Rasputin and the supreme power, while the cheap yellow as well as socialist press showed a great deal of professional correctness in the coverage of this theme.
