Abstract: Asthma is a chronic inflammatory disorder of the respiratory tract that can cause an increased response and activity within the airway which is characterized by the recurrent episodes of wheezing, shortness of breath, and cough accompanied by airway obstruction in varying degrees. Vitamin D plays a role in the pathogenesis of asthma. Many studies suggest a relation between vitamin D and calcium, which can be seen as a possible link between calcium levels and asthma. This study aimed to determine the correlation between the level of calcium and asthma attacks in children. This was a case-control study that gathered 21 asthmatic children and 19 non-asthmatic children with acute respiratory infections who did not use corticosteroids for the treatment at outpatient services Prof. Dr. R. D. Kandou Hospital Manado from January to June 2015. Calcium levels of asthmatic patients and non-asthmatic were noted. Statistical analysis using logistic regression with a P value < 0.05 were considered significant. The results of logistic regression analysis showed a significant association between calcium level and asthma attack (P = 0.04 with OR = 2.75). The average level of calcium in the asthmatic group was 9.2 mg/dL (0.81, 95% CI 8.91 to 9.64) and the non-asthmatic group was 8.7 mg/dL (0.72, 95% CI 8.38-9.07). Conclusion: There was a correlation between calcium level and asthma attack in children. The lower the level of calcium, the higher the chance of asthma attack.Keywords: children, asthma, calciumAbstrak: Asma adalah kelainan inflamasi kronis saluran pernapasan yang dapat menyebabkan peningkatan respon dan aktivitas jalan napas, ditandai dengan episode mengi berulang, sesak napas, dan batuk yang disertai obstruksi jalan napas dalam derajat bervariasi.

ECOLOGICAL AND MICROBIOLOGICAL ASSESSMENT OF SEWAGE SLUDGE OF WASTE TREATMENT PLANTS IN THE CITY OF ODESA
Authors: Dyshliuk V.Ye. , Pyliak N.V. , Loban L.L.
Published: July 2019

Objective. Investigate the number of microorganisms – representatives of various ecological trophic groups in mechanically dewatered and naturally disinfected sewage sludge (SS) of the biological sewage treatment plants (BSTP) “Pivnichna” and “Pivdenna” of the City of Odesa to determine their suitability for microbiological parameters for use as fertilizers in agriculture.

Methods. Microbiological, statistical.

Results. It was established that SS of BSTP “Pivdenna” and “Pivnichna” in the City of Odesa, bacteria that consume organic and mineral nitrogen compounds, phosphate-mobilizing microorganisms, are actively developing, due to the presence of the corresponding trophic substrates. By the number of ammonifiers, microorganisms that consume mineral compounds of phosphorus and bacteria capable of hydrolyzing the organophosphates, spore microorganisms, the waste is inferior to traditional organic manure – animal manure. The functional orientation of microbiological processes in the studied substrates is determined on the basis of the obtained data, calculations of the mineralization-immobilization factors and the oligotrophic index. The parameters of the mineralization-immobilization factors (0.04-0.2) in the SS indicate the predominance of synthesis processes over the destruction of organic matter. The oligotrophic index (an indicator of the supply of substrates with easily digestible nutrients) shows insignificant content of nutrients available for microorganisms in SS from BSTP “Pivnichna” (OI = 1.0) and a high level of supply with nutrients of SS from BSTP “Pivdenna” (OI = 0.1). In general, according to microbiological parameters, investigated SS are suitable for use as fertilizing substrates in agriculture.

Conclusion. Taking into account the obtained data and taking into account the results of previous studies on the compliance of SS with sanitary regulations, it can be considered that the use of SS as fertilizers will have a positive effect on the functioning of agrocenoses.
DEVELOPMENT OF MICROORGANISMS AND TRENDS OF BIOLOGICAL PROCESSES IN LEACHED CHORNOZEM UNDER SIMULATION OF DEFICIENCY OF THE FRESH ORGANIC MATTER AND THE INFLUENCE OF MINERAL NITROGEN
Authors: Volkohon V.V. , Brytan T.Yu. , Pyrih O.V.
Published: July 2019

Objective. Study the peculiarities of the development of microorganisms and trends of biological processes in the soil under the influence of mineral nitrogen under the conditions of simulation of the deficiency of fresh organic matter.

Methods. Microbiological, agrochemical, gas chromatographic, statistical.

Results. In the conditions of the vegetative experiment under the simulation of the deficiency of fresh organic matter (preparation of soil in accordance with the method of determining the content of humus) in the leached chornozem, the effect of increasing doses of mineral nitrogen on the dynamics of the number of representatives of certain ecological trophic groups of microorganisms and the course of soil-biological processes that accompany the mineralization of humus was studied. Nitrogen fertilizers, under given conditions, stimulate the development of ammonifiers, microorganisms that mainly utilize mineral compounds of nitrogen, denitrifiers, cellulolytic bacteria, activates biological nitrogen and carbon dioxide emission processes. In this case, the need for carbon to provide metabolic processes of microorganisms can meet only at the expense of destruction of humus compounds. When the fresh organic matter is introduced in the soil in the form of straw chopped to sawdust, as well as under the growth of barley, the activity of biological denitrification is reduced. At the end of the experiment, the content of total carbon in the soil has a clear tendency to decrease with increasing doses of mineral nitrogen – according to the variants: without fertilizers, control – 2.97 %, 13 mg N/kg of soil – 2.91 %, 26 mg N/kg – 2.88 %, 39 mg N/kg – 2.85 %.

Conclusion. Under the deficiency of fresh organic matter in leached chornozem, the depleted use of mineral nitrogen fertilizers, especially in large quantities, leads to the creation of a situation where microorganisms for the maintenance of metabolic needs use carbon-preservative organic compounds. The use of mineral nitrogen, not coordinated with the required amount of fresh organic matter, leads to the initiation of dehumidification processes. To prevent such effects, environmentally sound fertilizer systems for crops should include systematic entry of fresh organic matter into the soil.

Published: July 2019

In the present paper we investigate the effect of heat-treatment on geometry and mobility of Au nanoparticles (NPs) on Si substrate. Chemically synthesized Au nanoparticles with median diameter of 14 nm were annealed at 200°C, 400°C, 600°C and 800°C for 1 hour. Geometry changes from faceted towards more rounded shapes were observed already for 200oC and increased further for higher temperatures. According to KCM simulations NPs become rounded through the minimization of the surface area and transitioning to lower energy surface types {111} and {100}. Next, NPs were manipulated with AFM and it was found that the higher is annealing temperature, the less energy was required to displace the particle. However, after treatment at 800°C particles became immovable. We attributed this surprising effect to diffusion of gold into Si and to the growth of SiO2.

We present the discovery and statistical analysis of 12,660 spotted variable stars toward and inside the Galactic bulge from the Optical Gravitational Lensing Experiment (OGLE) data that are over two decades long. We devise a new method of dereddening of individual stars toward the Galactic bulge where strong and highly nonuniform extinction is present. In effect, 11,812 stars were classified as giants and 848 as dwarfs. Well-defined correlations among the luminosity, variability amplitude, and rotation period were found for the giants. Rapidly rotating dwarfs with periods P ≤ 2 days show I-band amplitudes <0.2 mag, which is substantially less than the amplitudes of up to 0.8 mag observed in giants and slowly rotating dwarfs. We also notice that amplitudes of stars brighter than I
0 ≈ 16 mag do not exceed 0.3–0.4 mag. We divide the stars into three groups characterized by correlation between light and color variations. The positive correlation is characteristic for stars that are cooler when fainter, which results from the variable coverage of the stellar surface with spots similar to the sunspots. The variability of stars that are cooler when brighter (negative correlation) can be characterized by chemical spots with an overabundance of heavy elements inside and a variable line-blanketing effect, which is observed in chemically peculiar stars. The null correlation may result from a very high level of the magnetic activity with rapidly variable magnetic fields. This division is readily visible on the color–magnitude diagram (CMD), which suggests that it may depend on the radius of the stars. We detect 79 flaring objects and discuss briefly their properties. Among others, we find that relative brightening during flares is correlated with brightness amplitude.

Published: July 2019

Le but de la présente étude est d’examiner le lien entre le traitement perceptuel et attentionnel des vrais et des faux sourires à l’aide de l’enregistrement des mouvements oculaires lors de la tâche de jugement de l’authenticité des sourires chez les enfants. Des enfants âgés de 6-7 ans et 9-10 ans sont exposés à des sourires comprenant les caractéristiques d’un sourire authentique (Duchenne symétrique) ainsi que des sourires sans l’activation du marqueur de Duchenne (non-Duchenne) et des sourires asymétriques (Duchenne asymétrique), deux signes de non-authenticité. Les résultats révèlent que les enfants, peu importe leur groupe d’âge, jugent le sourire Duchenne symétrique plus joyeux que le sourire Duchenne asymétrique et le sourire Duchenne asymétrique plus joyeux que le sourire non-Duchenne. Les participants donnent également la réponse attendue plus souvent pour le sourire Duchenne symétrique et le sourire non-Duchenne que pour le sourire Duchenne asymétrique. Toutefois, l’analyse des saccades et du temps de fixation ne révèle aucune différence significative en fonction du type de sourire (Duchenne symétrique, Duchenne asymétrique, non-Duchenne), et ce pour les deux groupes d’âge. En somme, les tendances des mouvements oculaires chez les enfants ne permettent pas d’écarter l’hypothèse des limites attentionnelles-perceptuelles. L’implication théorique des résultats est discutée en plus de faire le lien avec les études antérieures chez les adultes.
Un défi après la Grande Guerre : renouveler la diplomatie. Approche comparée des cas espagnol et français
Authors: Petrovici Zorann
Published: July 2019

Le nouvel ordre international, né à la fin de la Grande Guerre et incarné par la Société des Nations, pousse les diplomaties des divers États à adopter des pratiques et méthodes nouvelles. Dans cet article, nous analysons la position adoptée par l’Espagne et la France face au multilatéralisme, la principale de ces nouveautés, à travers quelques thèmes – la perte de souveraineté pour les nations, le caractère international des fonctionnaires en poste à Genève ou le poids de l’opinion publique par rapport à l’œuvre de la Société des Nations – ainsi que la façon dont chaque État adapte sa diplomatie à cette nouvelle réalité. Cette étude comparée nous permettra d’apprécier si le comportement d’un pays qui a maintenu sa neutralité pendant la guerre est différent de celui d’un autre État qui a été l’un des grands belligérants.

Les impensés philosophiques du jeu animal
Authors: Duquenne Vincent
Published: July 2019

S’il est évident que les animaux jouent, peu d’auteurs ont pris la peine de mentionner ce fait ou de s’y attarder. Sans doute était-ce parce que le jeu animal remet en cause l’idée d’un déterminisme instinctif fort et conduit à accorder à l’animal plus de liberté et de gratuité qu’on n’était prêt à le faire. Ce n’est qu’avec Karl Groos, en 1896, que le jeu animal fait l’objet d’une monographie, mais elle n’a pas constitué un tournant décisif dans la perception de l’animalité, car Groos se limite à tracer le programme de l’éthologie et réduit le jeu animal à la seule logique de l’évolution darwinienne. Une approche philosophique qui lui rende justice reste à construire.

Njen vršaj je odrezal severne ponore in preusmeril glavni dotok s polja proti zahodu, posredno na Planinsko polje. Zato so današnje hidrološke razmere v Planinski jami neposredna posledica dogajanj na Cerkniškem polju.Detailed study of the upper Cerkniščica’s catchment and its sediments in Cerkniško polje revealed that the river turned this direction in the middle Würm, while in the more remote past, the input to Cerkniško polje (and to the caves) was completely karstic. Its alluvial fan cut the main vertical ponors, and deflected the main polje outflow westwards, indirectly into Planinsko polje. Consequently, recent hydrogeological conditions in Planinska jama are a direct consequence of development in Cerkniško polje.

Skriti kras (cryptokarst) je kras, razvit pod prepustnim, vendar netopnim pokrovom. Nastane zaradi vode, ki prenika skozi krovne plasti. V krovnih plasteh se zbira voda, se poèasi preceja skoznje in razjeda matično kamnino. Zaradi tega nastanejo depresije, zapolnjene s pokrovnim sedimentom, in kraški stebri. Zaradi posedanja prepustnega pokrova, nastanejo na površju ulegnine. Če erozija odtsrani krovnino, se razgali relief, za katerega so značilni kraški stebri, razvalinasti relief in vrtače.Cryptokarst is a karst developed beneath a permeable and not karstifiable formation by percolating waters. The permeable rock acts as a storage of water which feeds slow seepage and infiltration enhancing the alteration of bedrock. The resulting forms consist of depressions, filled by the covering sediments, and pinnacles. The sinking of the permeable cover can produce depressions on the topographic surface. Erosion of the cover exposes a landscape characterised by pinnacles, ruinforms and dolines. In the Apulia region, cryptocorrosion surfaces are characterized by solution pipes 4-5 meters deep and with variable width (from a few centimeters to about one meter). Pipes walls are covered by a brownish carbonate crust, from a centimeter to more than 10 centimeters thick. The continental sands are only found in these depressions. The cryptocorrosion process took place late in the Middle Pleistocene on Quaternary marine abrasion terraces covered by no-carbonate sandy-silty continental deposits. The process stopped before the Last Interglacial age in response of an abrupt climatic change that induces a calcium carbonate precipitation and the formation of a carbonate crust.
Effects of the Tectonic Movements on the Karstification in Anatolia, Turkey
Authors: Atalay Ibrahim
Published: July 2019

V Turčiji so razvite različne kraške oblike, škraplje, jame, vrtače, uvale in polja. Zakrasevanje je odvisno tudi od tektonskih premikanj. Dobro razvite kraške oblike, kot velika polja, podzemeljski tokovi in jamski sistemi, so na široko razviti v mezozojskih apnencih v gorovju Taurus. Z dvigom Taurusa konec mezozoika se je na splošno pričelo zakrasevanje. V nekaterih velikih poljih so bila v neogenu jezera, v katerih sta se odlagala apnenec in glina. Sladkovodna jezera, kot Beyºehir in Egirdir, so v tektonsko-kraških depresijah. Sistemi podzemeljskih rek so med jezersko regijo (zahodni Taurus) in sredozemsko obalo. Ti sistemi so se spustili v globlje dele apnenčevega masiva zaradi napredovanja zakrasevanja in dviga Taurusa (zgornji terciar, spodnji kvartar). Jame so nastale kot rezultat teh navpičnih tektonskih premikov, zaradi katerih se je znižala erozijska baza. In tako se je proces zakrasevanja prestavil iz višjih v globlje dele Taurusa.Turkey has several types of karstic land-forms containing lapies (karren), caves, dolines, uvalas and poljes. Karstification is related also to the tectonic movements. Well-developed karstic features such as wide poljes, ground water and cave system are widespread in/on the Mesozoic comprehensive limestone in the Taurus Mountains. Karstification begun to develop towards the end of the Mesozoic by the uplift movements of the Taurus Mountains in general. Some large poljes were occupied by the Neogene lakes in which lime and clay accumulated. The fresh water lakes such as Lake Beyºehir and Egirdir are found in the tectonic-karstic depressions. Underground river systems are found between the Lake Region (western Taurus) and Mediterranean coast. These river systems have been shifted towards the deeper parts of the limestone as the result of the progress of karstification and the vertical uplift of the Taurus Mountains (upper Tertiary, Early Quaternary). Caves formed as the result of vertical tectonic movements. These movements caused the lowering of the base level. So the karstification process have shifted from the upper level to deeper parts of the Taurus.
Archduke Ludwig Salvator and Leptodirus Hohenwarti from Postojnska jama
Authors: Mader Brigitta

Avtor predstavi zgodovinski preparat hroščka Leptodirus hohenwarti Schmidt, ki je bil nedavno najden v hiši Evgenija Sforze (1820-1894) v Toskani. Dejstvo, da je bil Sforza tutor in spremljevalec avstrijskega nadvojvode in naravoslovca Ludvika Salvatorja (1847-1915), navaja avtorico na domnevo, da je ta drobnovratnik v zvezi z njegovimi naravoslovnimi zbirkami. Hroščka naj bi Ludvik Salvator domnevno dobil v Postojni 1863, ko je v spremstvu Evgenija Sforze prvič obiskal Postojnsko jamo.The author presents a historic preparation of a Leptodirus hohenwarti Schmidt recently found in the house of Eugenio Sforza (1820-1894) in Toscana.Because of the fact that Sforza has been the tutor and equerry of the Austrian Archduke and natural scientist Ludwig Salvator (1847-1915) a connection is presumed between Ludwig Salvator’s natural history collections and the Leptodirus-specimen, which was in the author’s opinion acquired in Postojna in 1863 on the occasion of Ludwig Salvator’s first visit to the caves, accompagnied by Eugenio Sforza.
Vulnerability Mapping in the Recharge Area of the Korentan Spring, Slovenia
Authors: Petrič Metka , Šebela Stanka
Published: July 2019

Zaradi dobro razvitega sistema kraških kanalov in razpok, ki omogoča hiter tok podzemne vode in tudi hiter prenos škodljivih snovi, so kraški vodonosniki zelo ranljivi za onesnaženje. Osnovo za njihovo ustrezno varovanje predstavljajo karte ranljivosti. Za izdelavo teh kart so bile razvite različne metode, pri oceni ranljivosti zaledja izvira Korentan pri Postojni pa smo uporabili metodo EPIK, ki je bila že večkrat uspešno preizkušena na krasu in stopnjo ranljivosti določa v odvisnosti od štirih parametrov: razvitosti epikrasa, učinkovitosti varovalnega pokrova, pogojev infiltracije in razvitosti kraške mreže. Za oceno posameznih parametrov smo uporabili različne raziskovalne metode kot so podrobno strukturno-litološko in geomorfološko kartiranje ter vzporedna analiza hidravličnih in fizikalno-kemičnih odzivov izvira na padavinske dogodke. Izdelana karta ranljivosti opredeljuje območja zelo velike, velike in zmerne ranljivosti znotraj zaledja izvira Korentana in jo lahko uporabimo kot osnovo za omejitev varstvenih pasov.Karst aquifers are very vulnerable to pollution due to well developed system of karst channels and fissures which enable fast groundwater flow and also fast transport of pollutants. An expert bases for their protection are vulnerability maps. Different methods for the construction of these maps were developed, and to assess the vulnerability of the recharge area of the Korentan spring near Postojna the EPIK method was used. In this method, which was many times successfully tested on karst, the degree of vulnerabilty is defined on the basis of four parameters: developement of the epikarst, effectiveness of the protective cover, infiltration conditions, and development of the karst network. For the assessment of individual parameters different research methods were used, such as detailed structural-lithological and geomorphological mapping, and combined analysis of hydraulic and physico-chemical responses of the spring to recharge events. Final result is the vulnerability map, which defines the areas of very high, high and moderate vulnerability within the recharge area of the Korentan spring and can be used to set up the protection zones.
Contribution to Knowledge of the Content of Heavy Metals (Pb, Cu, Zn and Cd) in Speleological Objects in the Risnjak National Park (Croatia)
Authors: Vrbek Boris , Buzjak Nenad
Published: July 2019

Vzorce mulja smo nabrali v šestih jamah v Narodnem parku Risnjak v Gorskem kotarju. Da bi kar najbolj omejili neposreden antropogeni vpliv, smo vzorčili v težko dostopnih razpokah in breznih. Vzorce smo pedološko analizirali in jim izmerili vsebnost težkih kovin. Rezultati so pokazali nizko vsebnost svinca, bakra in cinka, ki je nižja kot v večini hrvaških jam, medtem ko je vsebnost kadmija višja kot v drugih jamah. Vsebnost težkih kovin v jamah je nižja kot v humusnem horizontu.Samples of silt were taken from six speleological objects in the Risnjak National Park in Gorski kotar area (NW Croatia). The samples were taken from almost inaccessible rock fissures and shafts in order to find the most natural sediment outside the reach of anthropogenic pollution. The samples were examined in the Laboratory of the Forest Research Institute, where standard pedological analyses were performed, and the content of several heavy metals (Pb, Cu, Zn and Cd) was determined. The results indicate relatively low values of the content of lead, copper and zinc, while the values of cadmium in the sediment were increased above the limit level of 2 mgkg-1 in the majority of speleological objects. The content of other heavy metals (Pb, Cu and Zn) in mgkg-1 was lower than previously determined in samples taken from other speleological objects on the Croatian territory. Also, the content of heavy metals was lower in relation to surface soil samples taken from the humus horizon and mineral part of the soil under the parent rock of limestone, when sampling the soils of the Risnjak National Park.
Valvasor – A Common Error about his Publications on Cerkniško jezero, Slovenia
Authors: Shaw Trevor R.
Published: July 2019

Valvasor je svojo prvo, razmeroma preprosto razlago presihanja Cerkniškega jezera, objavljeno 1687, močno spremenil in zapletel v knjigi Die Ehre dess Hertzogthums Crain in članku v Acta Eruditorum, kar oboje je izšlo 1689. Sodobni avtorji, ki niso preverjali svojih virov, napačno navajajo, da gre za prevod članka iz 1687, namesto da bi opozorili na te velike spremembe in razlike v Valvasorjevih zamislih.Valvasorʼs first relatively simple explanation for the flooding and draining of the Cerkniško jezero lake, published in 1687, was greatly modified and complicated by 1689 when it appeared both in his book Die Ehre dess Hertzogthums Crain and in a paper in Acta Eruditorum. Modern authors who have not verified their sources have wrongly described the latter as a translation of the 1687 paper instead of recognizing the great change in Valvasorʼs ideas that it contains.
Los sefardíes y el hebreo: errores gráficos y de comprensión en las versiones judeoespañolas de cuatro midrašim hebreos
Authors: Romero Elena
Published: July 2019

En este artículo y a través de ejemplos basados en las versiones sefardíes de cuatro midrašim hebreos –Guedulat Mošé, Petirat Mošé, Ma‘asé Yerušalmí y Séfer Ben-Sirá–, se pretende mostrar el desconocimiento del hebreo del que, en ocasiones, hacen gala impresores y manuscribas sefardíes. La argumentación se basa en dos tipos de errores: 1) los gráficos, en los que las palabras hebreas se escriben a la «fonética», lo que especialmente en el caso de los impresos induce a pensar en una composición tipográfica al dictado; y 2) los que muestran la incomprensión de textos hebreos a la hora de traducirlos al judeoespañol, lo que puede dar como resultado pasajes, bien incomprensibles, bien hilarantes por disparatados.
Visualizando el pasado: el papel de las imágenes en la promoción de la identidad sefardí de los judíos de Sarajevo
Authors: Rajner Mirjam
Published: July 2019

El presente artículo examina el uso de las fotografías en el libro de Moritz Levy, dedicado a la historia de los sefardíes de Bosnia, que fue publicado en 1911. Aunque las fotografías acompañan la narrativa histórica intentando demostrar la preservación y continuidad de la identidad singular de los sefardíes bosnios a lo largo de los siglos, fueron, como se demuestra en el artículo, claramente una creación moderna. Visualmente destacadas e impregnadas de esteticismo, y fundadas en los álbumes oficiales otomanos de fotografía promocional, las orientalizadas imágenes austro-húngaras de la Bosnia ocupada y el nuevo arte judío. Como el resultado de esa novedad el libro de Levy sirvió de modelo para la representación de los sefardíes bosnios en las publicaciones judías yugoslavas posteriores. Sin embargo, debido a los eventos históricos turbulentos en la región, esas imágenes fueron politizadas y asumieron un papel conmemorativo y recientemente también han inspirado una renovación.
Doux commerce et droit naturel : la fable de la lex mercatoria
Authors: Marquer Éric
Published: July 2019

Pour justifier leur activité, les premiers mercantilistes anglais présentent le commerce comme une activité naturelle, qui favorise la paix entre les nations et contribue au progrès de la civilisation. Ils ont en particulier recours à la lex mercatoria, notion héritée du Moyen Âge. L’idée d’un commerce mutuel de l’humanité, mise en avant dans les écrits de marchands, mais également chez un auteur comme Grotius, contraste ainsi avec les théories de la souveraineté liée à un territoire national chez des penseurs politiques comme Francis Bacon, Thomas Hobbes et William Petty, ou à certains égards chez un juriste comme John Selden. Paradoxalement, alors que la constitution des empires coloniaux coïncide avec l’essor du grand négoce international, la liberté du commerce (free trade) est présentée par ses défenseurs comme une alternative à l’antagonisme entre les États et à la logique de domination induite par les théories modernes de l’imperium. Cette apparente contradiction entre la logique étatique et l’humanisme marchand – ou ce qui se présente comme tel – semble subsister dans les résurgences modernes de la lex mercatoria au XXe siècle. Pourtant, l’idée d’une source du droit indépendante de l’État et s’enracinant dans l’ancienneté des coutumes, l’uniformité des pratiques marchandes ou encore le jus gentium, relève en grande partie de la fable, et d’une construction idéologique visant à dissimuler la réalité des pratiques commerciales. De ce point de vue, la fable de la lex mercatoria joue très certainement un rôle important dans la constitution du topos du doux commerce et la promotion de la liberté des échanges par ceux qui en sont, directement ou indirectement, les principaux bénéficiaires.
