The effect of ashes on the properties of cement mortar and typical concrete fillers
Authors: Setina Janina , Juhnevica Inna , Baronins Janis
Published: December 2019

The production of heat and electricity from shale and biomass is leading to a significant increase in the amount of the combustion residues i.e. ashes. The utilization of ashes as the pozzolanic additive in the production of Portland cement mortar and concrete for the construction of lightweight structures is the most popular way. The interaction of ashes with other typical concrete fillers also can affect the final relative short-term and long-term properties of fresh and hardened concrete when designing the concrete mixture. The influence of wood and shale ashes on the properties of cement mortar and typical concrete fillers (sand, limestone, dolomite) – fresh mortar, hydration process, and hardened mortar were researched and assessed for their applicability in the production of concrete. The best results of mechanical strength, frost resistance and water absorption were measured in case of shale ashes containing samples in combination with cement and selected concrete additive – sand. Shale ashes can be recommended for application as the active additive. Since wood ash was exhibiting lower activity, it can also be applied as a filler to produce building materials.

Published: December 2019

The objective of this research is to develop a modeling and simulation approach for the bending stiffness of
sandwich panels which have been verified and compared by experimental results in normal condition and fire case. For
this purpose, polyisocyanurate (PIR) foam has been used as core material along with trapezoidal sheeting. In order to
simulate the experiments, Finite Element (FE) software ABAQUS has been applied. The modelling process contains
heat transfer analyses, mechanical analyses in normal condition and sequential analyses which includes the combination
of both mechanical analyses and thermal analyses. The main aim of this paper is to investigate the effect of fire on the
bending stiffness and stabilization of sandwich panels. Although with increase in temperature the strength of panels
decreases, this decline is not linear. The presented work should be considered as first step in STABFI project financed
by Research Fund for Coal and Steel (RFCS) which its purpose is to investigate translational and also torsional stiffness
of sandwich panels as future work. STABFI stands for steel cladding systems for stabilization of steel buildings in fire.

Published: December 2019

The concept of circular economy have gained a popularity in the scientific areas for the past decades due to
raising influence of climate change, overpopulation, deforestation, resource depletion, urbanization, pollution and other
global issues. Real estate is crucial aspect for every human being, because majority of people spend majority of their
lifetime in buildings which are mainly located in cities. Purpose of the study is to reflect how built environment and real
estate industry can benefit from the features of circular economy concept while promoting the practices of sustainable
development. Authors have carried out a study based on the methodology of literature review and state of the art review
to show how features of circular economy can support practices of sustainable construction. Results show that the
construction processes can be supported by features of circular economy throughout the whole life cycle of construction
project including logistics, supply chains, design, manufacturing process, exploitation and maintenance of real estate
and reusing the building materials. Research indicates that urban circular economy contributes to the development of
sustainable societies. Additionally, efficient implementation of circular construction requires profitability for majority
of stakeholders.

Authors: Volkova Viktorija , Pakrastinsh Leonids , Gaile Liga
Published: December 2019

This paper is devoted to the study of the dynamic behaviour of a tower structure with an attached damper.
Two dampers are attached to the upper end of the rod in two mutually perpendicular planes. The oscillation damper is
a mass attached to the rod by elastic coupling and a viscous friction. The mathematical model of the object being under consideration includes a system of two non-linear differential equations. The numerical simulation was used to
study the dynamic behavior of a dissipative system with limited excitation, containing a pendulum vibration damper.
The characteristics of the system amplitude − the speed of the wind flow is obtained. It is shown that the pendulum
vibration damper can significantly reduce the amplitudes of resonant oscillations of the cantilever rod. It is also shown
that the choice of system parameters makes it possible to avoid the establishing of resonant oscillations of the system.

Authors: Ciupack Yvonne , Ledecky Lukas , Kasper Yann , Geßler Achim , Albiez Matthias , Pasternak Hartmut , Ummenhofer Thomas , Feldmann Markus
Published: December 2019

In comparison to classic strengthening methods of fatigue-damaged steel structures, adhesively bonded CFRP
lamellas show several advantages. Compared to bolted reinforcement measures and the drilling of the crack tip, crosssectional weakening is avoided. Heat-induced, negatively acting residual stresses and distortions, usually occurring during repair welding, can also be excluded. Therefore, the effectiveness of adhesively bonded CFRP lamellas to enhance
the remaining lifetime of fatigue damaged steel structures is examined in a German research project. Selected results
are presented in this paper. To characterize the steel, CFRP and adhesive materials, different tests on small scale specimens are carried out. With the help of fatigue tests on CT-samples the remaining fatigue lifetimes of specimens strengthened with adhesively bonded CFRP lamellas is compared to the remaining lifetimes of specimens strengthened by established methods such as drilling the crack tip and repair welding. Based on the evaluation of the crack propagation
after the rehabilitation measures, the great potential of adhesively bonded CFRP reinforcements can be deduced. By
prestressing the lamellas, the remaining lifetime can generally be increased further. The combination of adhesively
bonded CFRP lamellas together with established rehabilitation methods shows a particularly high positive influence on
the remaining lifetime of the CT-specimens.
Volume changes of concrete in interaction with sliding joint
Authors: Kropacek Michal , Cajka Radim , Mynarcik Petr
Published: December 2019

The paper describes volume changes of cement plain concrete and steel fiber reinforced concrete with strength class C 30/37 in interaction with sliding joints. In the research experiment was performed large-dimensional specimens, on which volume changes were measured using string strain gauges. Below the large-dimensional specimens were designed sliding joints. The specimens were placed in a controlled laboratory environment and in an outdoor environment to simulate real conditions during construction and the measurements were carried out for several months. Volume changes of the concrete were compared to each other and significant influence of the sliding joints was observed. Significant influence on the development of volume changes also has dispersed reinforcement. Another part of the article is a comparison of experimental results with calculation models that allow to calculate the final shrinkage of concrete. Comparison results of volume changes with calculation models is important for demonstrating the effect of sliding joint, as currently valid calculation models do not consider the influence of subsoil and sliding joints, and the results are different as expected. For comparison model B4 (Bazant, 2015), model from technical standard EN 1992-1-1 (CSN EN 1992-1-1, 2006), model from fib model code 2010 (FIB, 2010) and model ACI (ACI, 2008) are used. The paper describes a unique experiment dealing with the influence of sliding joint on the development of volume changes of concrete from beginning of setting and hardening of concrete under precisely defined conditions, that allow comparison with calculation models and thus points to the shortcomings of the building practice.

Authors: Gałaj Jerzy , Drzymała Tomasz , Pełech Adam , Šukys Ritoldas
Published: December 2019

In the work, the distribution of the sprinkling intensity for a selected nozzle with the trade name Turbomatic
was tested and analysed. The device meets Polish legal requirements, has a CNBOP approval certificate and is classified
as a TURBO type nozzle. The research was aimed at extending the knowledge about spray jets generated by nozzles, in
particular analysing the impact of water flow rate on selected parameters of the sprinkling surface. These dependencies
can in practice save water and more effectively extinguish during rescue and firefighting operations. The tests were
carried out in the laboratory of the Rescue and Fire-Fighting Equipment of the Main School of Fire Service partly in
field conditions. Two different water flow rates of 200 and 400 dm3/min were assumed at a set operating pressure at the
nozzle outlet of 0.4 MPa. The position and methodology of conducted research was discussed. Selected results were
presented in tabular and graphical form. Their analysis was carried out and conclusions were made based on it. They
shows that the flow rate of the nozzle has a significant impact on sprinkling surface parameters such as: its size and
shape, range projection, maximum value of sprinkling intensity, location of maximum, etc.

Authors: Nazarenko Lidiia , Chirkov Aleksandr , Stolarski Henryk , Altenbach Holm
Published: December 2019

A mathematical model based on the concept of the energy-equivalent inhomogeneity combined with the
method of conditional moments (MCM) has been applied to analyze Carbon Nanotube (CNT)-reinforced materials. The
idea of the energy-equivalent inhomogeneity is to replace the inhomogeneity and its interphase by a single equivalent
inhomogeneity. It is evaluated for cylindrical inhomogeneity with Gurtin-Murdoch surface model and spring layer
model of interphases. Inclusion of multiple mechanisms in the description of interphases is applied to the CNT-reinforced materials. The CNT is modeled as a cylindrical high-stiffness surface. A weak zone surrounding the CNT can be
modeled by a spring layer. In this case, one Gurtin-Murdoch and one spring layer models would need to be combined.
To evaluate the effective properties of CNT-reinforced materials a statistical method, the MCM, has been employed
which describes random distribution of CNT’s. Closed-form formulas for the components of the effective stiffness tensor of such composites have been developed. A composite plate weakened by a hole under different types of loading is
considered. It is assumed, that the plate made of the polymer with randomly distributed and disoriented CNT’s. Analysis
of how various special distributions of CNT concentration affect the response of this plate is performed.

Authors: Jokūbaitis Aidas , Marčiukaitis Gediminas , Valivonis Juozas
Published: December 2019

Prestressed concrete railway sleepers are the most widespread sleepers due to their stiffness and high bearing capacity. They transfer train induced loads from the rails directly to the ballast and therefore are the most important part of the railway structure. As railway traffic is constantly increasing with increasing loads and additional environmental effects take place it is necessary to ensure safety of the railway. Therefore, the present study focuses on durability of prestressed concrete railway sleepers. This paper examines new sleepers and sleepers damaged during exploitation. As all sleepers were manufactured at the same time the comparison of cracking loads and bearing capacity are provided. Additionaly, a difference between chemical composition of concrete samples from new and exploited sleepers is briefly discussed. Further, possible causes of damages of exploited sleepers are analyzed.

Published: December 2019

Close relation of modal properties to mechanical properties of structures presents interest for applied research
and solutions of Structural Health Monitoring (SHM) tasks. The paper considers application of analytical and modal
analysis techniques for structural research and monitoring of composite blades as well as required measurement tools.
The Roving Hummer Technique (RHT) and Operational Modal Analysis OMA) were admitted as optimal methods for
modal properties estimation, but 3-axial accelerometers and vibration deformation sensors – as most acceptable measurement tools. There is discussion of methodology and technical aspects required for modal properties estimation of
static and rotating blades. Samples of composite blades preparation for measurements and equipment applied for testing
are considered. Authors discuss the modal passport concept as the platform for applied studies of modal properties and
for diagnostic purposes including Structural Health Monitoring (SHM) of operating structures. Typical modal passport
structure is described as the set of modal parameters that are common for same type of blades and generalized dependences of modal parameters from operational factors. The paper discusses the principles of modal passport application
for a particular blade based on its individual modal properties. There are conclusions about application of typical modal
passport in industry.
Non-linear analysis of slab-column connections with openings
Authors: Kormosova Ludmila , Augustin Tomas , Halvonik Jaroslav
Published: December 2019

This paper is focused on the assessment of punching capacity of the slab-column connections without transverse reinforcement with openings located close to a column. Non-linear analysis and design equations from the relevant
codes of practise are used for the prediction of the punching resistance of flat slab specimens supported by the rectangular columns with different ratio h/d of the column’s cross-section. The non-linear models were calibrated using experimental results from the laboratory tests. The main goal of the study is an investigation of the effect of the openings
on the punching capacity and as well as testing accuracy of the design equations for the prediction of the punching
resistance. Several methods for the reduction of the control perimeter length accounting for presence of the openings
were tested in order to find the most general method for the estimation of the punching capacity. However, standard
methods introduced in the relevant codes of practise provide very inconsistent results concerning of the model’s safety
for different position of the openings as well as for different cross-section of the columns. Therefore modification of the
methods was proposed and verified using obtained results.

Currently, the construction sector is facing requirements for higher quality and efficiency standards as well
as objectives related to value creation. In construction, rational decision-making problems often involve creating a
unique complex of criteria, which must consider multiple requirements and conditions. The paper presents the developed
model for the selection of multi-layered external walls of a residential building. The model considers the following
aspects and parameters: time, cost, quality, environmental conditions, aspects of sustainable development, and problemsolving benefits received from the assessment of alternatives and the development of the model. Game theory was used
to calculate the defining rational decision. For the calculations was used game theory: Bayes, Wald’s rule, Savage criterion, Laplace’s rule. This study presents the developed model for the selection of multi-layered external walls of a
residential building and calculation results based on game-theory rules, which are effective tools for rational decisionmaking.

Authors: Laera Rossana , Pérez Inmaculada Martínez , Fernández Luis de Pereda , Caballero Ricardo Tendero , Iannone Francesco
Published: December 2019

Thermally Activated Building Systems (TABS) play a major role in building envelope integration. TABS operate at low temperatures, enabling efficient utilization of renewable sources. Moreover, their combination with other building energy systems provides a high degree of dynamic interactivity with users, improving the quality of the indoor thermal environment. In this research, the efficiency of the technology of active pipe-embedded structures is investigated within its practical application in an existing office building energy retrofit in Spain. Concrete Core Activation (CCA) of the original horizontal structure aims at exploiting its thermal inertial properties and potential storage capability in combination with low-grade energy production systems and devices, such as geothermal heat pumps. A proper methodology of energy diagnosis is aimed at the optimization of TABS performance in building retrofitting. Significant energy savings could be achieved by applying appropriate solutions, control strategies and corrective actions for TABS. The continuity of energy management and follow-up has been proven necessary to keep high standards in terms of TABS energy performance, targeting the identification of energy saving opportunities for the improvement of energy efficiency.
Investigation of Portland cement composites containing high amounts of different kinds of fly ashes
Authors: Wilińska Iwona , Pacewska Barbara , Kubissa Wojciech
Published: December 2019

Utilization of fluidized fly ash in cement composite is problematic, e.g. because of its changeable chemical composition and increased water demand of the mixture. However, this kind of by-product shows some self-cementing properties, which may be beneficial for low-cement mixtures. The article compares the impact of various kinds of fly ashes, i.e. fluidized fly ash and conventional one, and their mixtures on hydration of fly ash–cement compositions in relation to properties of final material. The amount of fly ash in the binder was 50 wt%. Calorimetry, thermal analysis (TG/DTG) and infrared spectroscopy were used. Compressive strength and water absorption of hardened composites were also registered. It was found that both fly ashes exhibit delay effect in fly ash-cement pastes which causes extension of initial setting time and lower heat released compared to the reference without fly ash. At later hydration days, fluidized fly ash develops higher pozzolanic activity than conventional one. Compositions with fluidized fly ash show better compressive strength compared to those containing conventional one. Mixing of different materials of high and low activity (fluidized and conventional fly ash in this case) seems to be a good way for creation of new cement replacement material.

Design analysis of strengthening a damaged supporting structure in a swimming pool building
Authors: Kruszka Leopold , Chmielewski Ryszard
Published: December 2019

The issue of strengthening the supporting structure of the swimming pool building, with a special attention
on damaged reinforced concrete pillars in the sub-pool, is presented. The technical condition of those pillars in the
basement of the swimming pool was defined as the risk of structural collapse. Numerous cracks and the occurrence of
deformation of reinforcing bars were noticed. Three columns were damaged in basement rooms. First of all, the cause
of damage was determined. The actual load carrying capacity of the built pillars was checked. To this aim, the geometry
of the columns was checked first and the actual strength class of built-in concrete. It was found that all columns were
made of concrete of the same strength class and good homogeneity of concrete, but this concrete did not meet the
standard requirements as a construction material for reinforced concrete structures. The new supporting structure was
designed in the form of four-leg cross-sections made of an isosceles angle profile. Due to structural damage, an additional safety factor was adopted, increasing the total load per pillar by 50%. This approach took into account the possible
redistribution of loads in the building structure that occurred as a result of damages.
Design errors and performance defects as causes of the risk for a collapse of the ceiling of the concert hall
Authors: Chmielewski Ryszard , Kruszka Leopold
Published: December 2019

The issue presented concerns the proper assessment of a ceiling underneath a modernised concert hall in a
historic building as a case study. The reason for a reconstruction was to replace a wood block floor with stone slab floor
made of marble. Shortly after the construction works, cracks which appeared, made the floor unsuitable for further use.
In order to determine the cause of the damage, a detailed analysis of a state of the construction was performed within
the technical diagnostics. The first element that was inspected was the way the cracks were distributed. This layout was
typical for overloading of ceiling. It was assumed that the thickness of the concrete overlay of the Ackerman floor was
9 cm. In order to verify the actual layout of the floor layers, five different opencast works were taken from the top level
of the floor cavity blocks. The actual layout of the uncovered parts differed from both the assumptions that were made
and the new design. The arrangement of the floor layers that differed from the design documents, caused the overloading
of the supporting structure of the Ackerman floor. Additionally, an incorrect design assumption has overlapped.
Study of the influence of the secondary raw materials on microstructure and properties of calcium silicate composite
Authors: Húšťavová Jana , Černý Vít , Drochytka Rostislav
Published: December 2019

Calcium silicate composites are a widely used building material, especially autoclaved aerated concrete or
sand-lime bricks. The physico-mechanical properties of these materials depend on their microstructure. Microstructure
is characterized by the content of crystalline calcium silicate compounds that arise during autoclaving. This is in particular the tobermorite mineral, which carries the mechanical strength of the composite. This paper focuses on the influence
of secondary raw materials on properties and microstructure of the calcium silicate composite. Secondary raw materials
were selected as slag from the combustion of lignite and ground glass. Mixtures of composites were selected with respect
to the required C/S molar ratio of 0.73. The hydrothermal treatment was carried out at a temperature of 190 °C and a
residence time of 4, 8 and 16 hours. The microstructure of calcium silicate composites and autoclaved aerated concrete
was studied. The use of slag resulted in an increase in the intensity of the diffraction line of tobermorite by X-ray
diffraction analysis as well as the use of glass. The difference was particularly evident in the shape of the tobermorite
crystals. Long strong crystals were detected in the sample with slag, while the sample with glass exhibited low tobermorite leaves. Porous structure of autoclaved aerated concrete with slag was uniform, unlike samples with glass. Both
materials have a positive effect on the increase in compressive strengths of the samples.

Published: December 2019

Optimization procedures offer a possibility for time-effective determination of input parameters values for
complex soil constitutive models. The following paper presents a combination of the metaheuristic Particle swarm optimization method (PSO) and commercially available solver based on the finite element method (FEM). After the brief
theoretical description, different alternatives to the PSO method are reviewed and tested. An optimal alternative is chosen and further used. In the second part of the paper, the combination PSO – FEM is utilized for a fully automatic
derivation of input parameters values for the Hardening small strain model from pressuremeter tests. Predicted pressurevolume curves from the axisymmetric FE model gradually converge towards the measured curve until the accuracy
criterion is reached.

Published: December 2019

BACKGROUND: Pediatric supracondylar humerus fracture (SHF) is a complicated injury which can result in severe sequela. Nowadays, closed reduction and percutaneous pinning (CRPP) is the most popular treatment.
AIM: This study had two aims (1) checking the result of treating pediatric SHF patients without neurovascular injury by CRPP under image intensifier, and (2) analysing neurovascular complications of CRPP in treating these patients.
METHODS: We conducted a research on 42 patients from February 2018 to March 2019. The age of patients ranged from 3 to 11 years old, with a mean of 5. There was a male predominance with a male / female ratio of 3/1. The average duration of the procedure was 46 minutes, and there was no failed case.
RESULTS: Result evaluation based on Flynn criteria (1974): 85.74 % excellent, 9.5% good, 2.38% fair, and 2.38% poor. There was 1 patient how got ulnar nerve injury complication after medial-lateral crossed pinning, making up 2.38% of all cases. This case was a late admission – 3 days after being injured – and the elbow was badly swollen, so locating the medial condyle for pin placement was very problematic, this the ulnar nerve could be damaged during K-wire pinning. The K-wires are removed after 4 weeks.
CONCLUSION: CRPP under image intensifier in treating pediatric supracondylar humerus fracture is an effective treatment and with good treatment result.

Leaf- and fruit-feeding chrysomelids (Coleoptera) on bananas and plantains (Musaceae, Zingiberales) cause major losses to banana growers in the northern and northeastern regions of India, Bangladesh, and other parts of Southeast Asia. The species composition of these beetles has not been studied so far in India and wrong names or wrong name combinations in the literature have caused confusion. Most particularly, the Central and South American apecies ofColaspis hypochloraLefèvre (Chrysomelidae, Eumolpinae) has been erroneously reported as occurring in India and Bangladesh, and this name has been used for the Indian species. Based on extensive surveys for leaf- and fruit-feeding chrysomelids in the northern and northeastern regions of India from 2015 to 2019, three species of banana-feeding chrysomelids, namely,Basilepta subcostata(Jacoby) (Eumolpinae),Bhamoina varipes(Jacoby), and a new species,Sphaeroderma cruentasp. nov.(Galerucinae, Alticini), are documented. Of these, the latter two are recorded as pests of banana in India for the first time. An illustrated diagnostic account of these three species is given to facilitate their identification by economic entomologists. COI sequences of populations ofB. subcostatafrom Assam and Uttar Pradesh showed 98–100% homology, indicating that these populations are conspecific and that COI sequences can be used for rapid species determination. Brief notes on the biology and available management options for these pests are also given.

The introduction of mammals on oceanic islands currently threatens or has caused the extinction of many endemic species. Cats and rats represent the major threat for 40 % of currently endangered island bird species. Direct (predation) and/or indirect (exploitative competition for food resource) trophic interactions are key mechanisms by which invaders cause the decrease or extinction of native populations. Here, we investigated both direct and indirect trophic interactions amongst four predator species (i.e. animals that hunt, kill and feed on other animals), including three introduced mammals (Felis silvestris catus, Rattus rattus and Rattus exulans) and one critically endangered native bird, the Niau kingfisher (Todiramphus gertrudae). All four species’ diets and prey availability were assessed from sampling at the six main kingfisher habitats on Niau Island during the breeding season. Diet analyses were conducted on 578 cat scats, 295 rat digestive tracts (218 R. exulans and 77 R. rattus) and 186 kingfisher pellets. Despite simultaneous use of morphological and PCR-based methods, no bird remains in cat and rat diet samples could be assigned to the Niau kingfisher, weakening the hypothesis of current intense predation pressure. However, we determined that Niau kingfishers mainly feed on introduced and/or cryptogenic prey and highlighted the potential for exploitative competition between this bird and both introduced rat species (for Dictyoptera, Coleoptera and Scincidae). We recommend removing the cats and both rat species, at least within kingfisher breeding and foraging areas (e.g. mechanical or chemical control, cat sterilisation, biosecurity reinforcement), to simultaneously decrease predation risk, increase key prey availability and boost kingfisher population dynamics.
L'avocat et l'algorithme
Authors: Milburn Philip
Published: December 2019

L'article s'interroge dans un premier temps sur le travail et les compétences réels des avocats, au-delà des discours et de la rhétorique de la profession. Cet examen en détail de la nature de cette activité concrète permet de poser quelques linéaments quant à la manière dont les services juridiques offerts par l'intelligence artificielle sont susceptibles de venir l'impacter, d'après les publications de Richard Susskind. Afin d'éviter une disqualification économique de leur expertise, les avocats doivent prendre conscience et mettre en valeur la part non juridique de leur compétence.
Politicizations by ‘UK’ European Commissioners During Exit Referenda: The Impact of Institutionalized Roles
Authors: Smith Andy
Published: December 2019

En se fondant sur les théories constructivistes, cet article est centré sur la manière dont les commissaires européens sont intervenus dans l’espace public pour politiser des questions liées à l'intégration européenne en invoquant des valeurs et des principes ou, au contraire, en les dépolitisant par des discours exprimés en termes de " nécessité ", " efficience " ou " faisabilité technique ". Sur le plan empirique, les données sont mobilisées pour comparer la manière dont les commissaires britanniques ont prononcé des discours sur l'Union européenne "chez eux" dans les contextes des référendums d'adhésion. Cette étude montre que dans les débats qui ont précédé le vote Brexit, le dernier commissaire britannique a clairement beaucoup moins politisé l'UE que ses prédécesseurs lors de la campagne équivalente en 1975. Ce changement ne réside pas simplement dans des variables contextuelles telles qu'un changement de la politique de l'UE ou du parti britannique. Il découle également des profondes modifications du rôle institutionnalisé d'un commissaire depuis la chute du collège Santer en 1999.
La thérapie de Pleine Conscience : une médiation articulant les espaces psychiques et corporels
Authors: Bazin Anne-Sophie
Published: December 2019

Les thérapies psychocorporelles ont une place essentielle en addictologie où les patients sont dans des tentatives psychosomatiques de venir à bout de leur souffrance. Les carences dans le maternage ou les stimulations précoces traumatiques induisent une défaillance dans les capacités pare-excitantes. L’éprouvé de sensations tonico-sensorielles contenantes et sécurisantes modèle les représentations que le patient a de lui-même et du monde. Il lui sera alors possible d’éprouver progressivement ses affects sans crainte d’effondrement. Le yoga et la méditation sont les pratiques qui inspirent l’approche psychocorporelle présentée dans cet article. Elles ont pour perspectives d’assouplir le clivage psyché-soma et de contenir la réactivité liée à l’activité mentale. Cette approche est présentée par le prisme d’une pratique au centre médical Marmottan.
Addictions et pratique du shiatsu
Authors: Mehdaoui Youssef
Published: December 2019

Chez les patients addicts, le stress, les conflits, la violence, les abus, le manque de communication tendent à perturber leur équilibre et, en particulier, les structures énergétiques. Cela crée des blocages dans la circulation des énergies intérieures. Nous verrons dans cet article comment la prise en charge shiatsu peut restaurer l’image de ces patients via la sensation de leur enveloppe corporelle et donc de leur mémoire connectée à leur histoire. Des vignettes cliniques viendront illustrer la description de la pratique.
Troubles de l’usage de l’alcool et Rorschach : défaut du Moi corporel et évitement psychique
Authors: Gaudriault Pierre , Jacquet Marie-Madeleine
Published: December 2019

À partir des travaux psychanalytiques portant sur le mécanisme d’évitement psychique évoqué par S. Fraiberg et A. Green d’une part, et sur les troubles du Moi corporel décrits par G. Haag d’autre part, les auteurs font l’hypothèse que ces phénomènes impactent le Rorschach de patients souffrant d’addiction alcoolique (AUD). Les Rorschach de 58 patients AUD comparés à 58 patients souffrants de troubles psychiatriques divers non addictifs (PSY) montrent des signes d’évitement préalable dans un quart des sujets des deux groupes. Chez les patients restants, les kinesthésies mineures, les réponses contre-expressives et les réponses Pénétration sont significativement plus nombreuses chez les AUD. Ces résultats vont dans le sens de l’évitement psychique et des troubles du Moi corporel chez ces patients, éclairant la question de leur engagement dans les soins.
L’addictologie : d’une néo-discipline et de son homogénéité. Conditions historiques de son émergence en France
Authors: Dugarin Jean
Published: December 2019

À la toute fin du XX e  siècle est apparue en France une nouvelle discipline, l’addictologie. L’Université s’en est emparée et nombre d’enseignements ont été proposés, d’inspirations diverses, s’adressant à des publics variés. Ainsi est né un praticien d’un style nouveau, l’addictologue. En miroir, un patient nouveau s’est dessiné « l’addict », avatar récent tout à la fois de l’alcoolique, du toxicomane, du pharmacodépendant et du dépendant comportemental. Son homogénéité conceptuelle tant sur le plan clinique que social continue à être discutée. Les professionnels s’interrogent sur ses définitions et sur les diagnostics différentiels à partir de grilles de lecture d’horizons divers. Les patients eux-mêmes peinent, parfois, tant les stéréotypes sont figés en la matière et les contextes différents, à voir ce qu’il peut y avoir de commun entre un usager de crack, un fumeur de tabac et un « cyberaddict ». Dans le champ de l’addictologie plus qu’ailleurs se pose le problème des statuts alloués à l’« addict », les statuts ontologiques, cliniques, éthiques, juridiques pouvant venir s’interpénétrer. Pour tenter d’y voir un peu plus clair, ce texte va proposer une remise en perspective historique, où nous verrons d’abord comment le XIX e  siècle va réunir les conditions d’une problématisation débouchant sur l’apparition progressive de l’image de l’alcoolique et du toxicomane. Puis, au XXe siècle, viendront les textes de loi, et notamment la loi du 31 décembre 1970 qui va logiquement poser la question d’un système de soins spécifique (sa nature, ses acteurs, ses références théoriques).
Los huesos olvidados del dolmen de Carrascal (Agualva, Sintra, Portugal). Examinando los restos humanos antiguos
Authors: Silva Ana Maria , Sousa Ana Catarina , Boaventura (†) Rui , Scarre Chris
Published: December 2019

El dolmen de Carrascal (Sintra, Portugal) fue descubierto a finales del siglo XIX. Los restos óseos humanos depositados en el Museu dos Serviços Geológicos (Lisboa) han sido re-analizados con un programa que investiga el estilo de vida de las poblaciones del Neolítico Final de las regiones del centro/sur de Portugal.Según los recientes trabajos de campo enmarcados en el proyecto de Recuperación y Valorización del monumento llevados a cabo por el Municipio de Sintra, estos han permitido clarificar aspectos de la construcción y la recuperación del material osteológico y arqueológico.Los datos de radiocarbono de los restos óseos humanos nos permiten encuadrar las prácticas funerarias en una fase inicial del megalitismo en el oeste de la península ibérica. La colección comprende un mínimo de 9 adultos (ambos sexos) y 5 no adultos.Se han observado evidencias de enfermedades infecciosas, cambios degenerativos, alteraciones metabólicas y una trepanación remodelada realizada en un parietal derecho.Los restos dentales ofrecen información particularmente interesante con respecto a otros usos no masticatorios de los dientes. Esto se manifiesta en forma de astillas y agujeros en los dientes anteriores.Estos datos han sido comparados con otras colecciones contemporáneas de Portugal con el objetivo de observar la salud y el comportamiento de estas poblaciones prehistóricas.
De la philosophie à l’histoire, en passant par la psychologie : que nous apprennent les archives Foucault des années 1950 ?
Authors: Basso Elisabetta
Published: December 2019

Cet article s’appuie sur des manuscrits foucaldiens des années 1950 afin d’analyser le chantier théorique à partir duquel le jeune Foucault inaugure la réflexion qui l’amènera à une mise en question radicale des sciences humaines. En particulier, l’article suit la piste d’un ouvrage inédit que Foucault a consacré à l’analyse existentielle de Ludwig Binswanger à l’époque de son enseignement à Lille. Ce manuscrit représente le maillon manquant entre l’« Introduction » à Le rêve et l’existence (1954) et la thèse que Foucault publie en 1961, Folie et déraison. Tout en adjoignant à l’analyse du manuscrit la lecture de notes et fiches de lecture de la même époque, l’article montre que la critique que Foucault finit par adresser à l’anthropologie et la phénoménologie au début des années 1960 serait déjà présente de manière implicite dans l’« Introduction » à Le rêve et l’existence. Dans cette étude, en effet, Foucault aurait déjà abandonné son enthousiasme initial pour l’anthropologie phénoménologique de Binswanger pour focaliser plutôt son attention sur le problème du langage et de l’historicité des formes d’expériences.
Reconstruction of the Old Institutions
Authors: Asal Ugur Yasin , Ekren Nazım
Published: December 2019

The recent global economic and financial crisis has fundamentally questioned the crisis management mechanisms of the international institutions. Despite the development of the skills of these institutions, financial vulnerability, economic imbalances, and the instability of the macroeconomic performance indicators are still rising cyclically. The G20 represents roughly 85% percent of global GDP and two-thirds of the world population. It emerged as a leading body for international economic performance. The lack of permanent secretariat of the G20 is decreasing the effectiveness, legitimacy, and the economic viability of the club. Regarding this philosophical background, the role of G20s' institutional structure is examined according to institutional capacity and the macroeconomic performance of the club.
