Published: July 2018

BACKGROUND:

In vivo animal assays are a cornerstone of preclinical pain research. An optimal stimulus for determining the activity of potential analgesics would produce responses of a consistent magnitude on repeated testing. Intraplantar (i.pl.) injection of hypertonic saline (HS) in mice produces robust nociceptive responses to different analgesics, without evidence of tissue damage. Here, we investigated whether the nociceptive response is changed by repeating the injection at different times and sites in a mouse and whether it is attenuated by morphine.

METHODS:

We conducted randomized and blinded experiments to assess responses to repeated i.pl. 10% HS in female CD-1 mice. An injection of HS was followed by a second injection into the same hind paw at 4 hours, 24 hours, or 7 days. A separate group of mice each received i.pl. injections at 5, 10, and 15 days. In 2 independent experiments, 30 minutes after initial HS injections in the ipsilateral hind paw, mice received HS injection into the contralateral hind paw or ipsilateral forepaw. The ability of morphine to block the nociceptive responses was examined by injecting morphine at 5-day intervals.

RESULTS:

Repeated injection of HS did not alter the responses at 4 hours (84 vs 75 seconds; mean difference [95% CI], −9 [−40 to 23]; P = .6), 24 hours (122 vs 113 seconds; −6 [−24 to 12]; P = .5), or 7 days (112 vs 113 seconds; −0.3 [−12 to 11]; P = .95) or at multiple injections (day 0, 122 seconds vs day 5, 121 seconds; −0.3 [−28 to 27], P > .99; day 10, 118 seconds; 2.5 [−36 to 41], P = .99; day 15, 119 seconds; 2 [−36 to 38], P = .99). A previous hind paw injection did not change the responses of the contralateral hind paw (right, 93 seconds versus left, 96 seconds; −3 [−20 to 13], P = .7) or of the ipsilateral forepaw (forepaw after HS, 146 seconds versus forepaw after 0.9% saline, 149 seconds; −3 [−28 to 22], P = .8). Morphine dose-dependently attenuated HS responses (control, 94 seconds vs 4 mg/kg, 66 seconds; 29 [−7 to 64], P = .12; vs 10 mg/kg, 27 seconds; 67 [44–90], P < .0001; 4 vs 10 mg/kg, 67 [44–90], P = .03).

CONCLUSIONS:

The repetition of i.pl. HS produces consistent reproducible responses without tissue damage. This results in efficient, rapid detection of analgesic activity, reducing the number of animals required.
Fiscal Rules and Discretion in a World Economy
Authors: Halac Marina , Yared Pierre
Published: July 2018

Governments are present-biased toward spending. Fiscal rules are deficit limits that trade off commitment to not overspend and flexibility to react to shocks. We compare coordinated rules, chosen jointly by a group of countries, to uncoordinated rules. If governments’ present bias is small, coordinated rules are tighter than uncoordinated rules: individual countries do not internalize the redistributive effect of interest rates. However, if the bias is large, coordinated rules are slacker: countries do not internalize the disciplining effect of interest rates. Surplus limits enhance welfare, and increased savings by some countries or outside economies can hurt the rest. (JEL D82, E43, E62, H62)
Government Old-Age Support and Labor Supply: Evidence from the Old Age Assistance Program
Authors: Fetter Daniel K. , Lockwood Lee M.
Published: July 2018

Many government programs transfer resources to older people and implicitly or explicitly tax their labor. We shed new light on the labor supply and welfare effects of such programs by investigating the Old Age Assistance Program (OAA). Exploiting the large differences in OAA programs across states and Census data on the entire US population in 1940, we find that OAA reduced the labor force participation rate among men aged 65–74 by 8.5 percentage points, more than one-half of its 1930–1940 decline, but that OAA’s implicit taxation of earnings imposed only small welfare costs on recipients.

Limites das assimetrias regulatórias e contratuais: o caso dos aeroportos
Authors: Marques Neto Floriano de Azevedo , Zago Marina Fontão
Published: July 2018

Limits of regulatory and contractual asymmetries: the case of the Brazilian airport infrastructure Embora uma regulação técnica implique captar e compreender as especificidades das cadeias e das atividades setoriais, essa modulação regulatória não autoriza distinções ilimitadas entre atores e atividades equivalentes, sob pena de se afrontar a isonomia e distorcer a concorrência, com impactos na qualidade do serviço a ser prestado ao consumidor. Este artigo defende que as assimetrias regulatórias (assim consideradas as regras diferenciadas para atores de um mesmo setor ou mesmo de uma mesma cadeia setorial) devem ser previstas se e na medida necessária para efetivar a pauta da política pública setorial. Além disso, o artigo define as balizas, de forma abstrata, para as assimetrias regulatórias, e depois as aplica a um caso concreto: o setor de infraestrutura aeroportuária, que possui diversidade de modelos exploratórios e contratos de concessões, o que permite distinguir as assimetrias regulatórias (decorrentes de sujeição geral e abstrata) das assimetrias contratuais (decorrentes de sujeição específica e concreta). Por fim, concluímos que as assimetrias regulatórias que extrapolam as balizas antes apontadas podem ser contestadas, administrativa ou judicialmente. In order to achieve a well-done technical regulation, it is necessary to deeply understand the specificities of one sector chains and activities. However, this regulatory modulation does not authorize unlimited distinctions between equivalent players and activities, otherwise it could violate the equal protection rule and distort competition, with impacts on the quality of the service to be provided to the consumers. This article argues that regulatory asymmetries (herein considered as the enactment of differentiated rules for players within the same sector or even the same sectorial chain) should be predicted if and to the extent necessary to implement the sectorial public policy agenda. Furthermore, the article establishes the generic limits of the regulatory asymmetries, and then applies them to a case study: the Brazilian airport infrastructure, formed by different exploitation regimes and concession agreements, which allows us to distinguish the regulatory asymmetries (arising from general and abstract subjection) from the contractual asymmetries (arising from specific and concrete subjection). In conclusion, we argue that regulatory asymmetries that overpass the aforementioned mentioned limits can be challenged with administrative or judicial procedures.

A construção social do espaço para si: pertencimento na biografia de um migrante
Authors: Sangalli Lucas Cé
Published: July 2018

Teoricamente fundamentada na tradição da sociologia de orientação fenomenológica (A. Schütz), da sociologia do conhecimento (P. Berger; T. Luckmann) e da sociologia dos processos e figurações (N. Elias), essa investigação utilizou o método de entrevista narrativa biográfica de matriz alemã (F. Schütze; G. Rosenthal) para reconstruir os processos de construção do pertencimento na biografia de um indivíduo migrante. Os resultados da investigação esclarecem a constituição processual do pertencimento e enfatizam a dimensão do movimento na biografia do indivíduo, colocando em perspectiva questões raciais e de pertencimento derivadas das vivências nas figurações sociais pelas quais se deslocou, em países como Haiti, Equador, Peru e Brasil.

Authors: Piazzi Giulia
Published: July 2018

Este artigo discute a produção editorial de um livro de futebol como estratégia de marketing esportivo, tendo como objeto de análise o livro Cruzeiro Tetracampeão Brasileiro 2014, de Guilherme Guimarães e Thiago Soraggi. Para esta avaliação, considerou-se o sítio eletrônico da obra, bem como uma pequena entrevista realizada com um dos autores via e-mail, e analisou-se o caso sob os preceitos editoriais contemporâneos de Schiffrin (2006; 2011) e Thompson (2013) e a partir do conceito de marketing esportivo de Melo Neto (2007; 2013). Além da discussão a respeito do processo de publicação do livro sob os holofotes da conquista do Campeonato Brasileiro pelo clube em questão, pretendeu-se também avaliar brevemente o interesse dos leitores-torcedores pelo produto, cujo público denominou-se mais restrito (colecionadores). Como conclusão, foi possível confirmar o êxito do livro dentro de sua proposta, bem como o valor do produto para o público-alvo e a sua relevância para o registro de uma memória recente, com as peculiaridades da produção de uma edição independente e licenciada. Ademais, a análise permitiu notar que algumas estratégias antigas de marketing do mercado de livros de futebol ainda são mantidas e usadas nos dias atuais.

Futebol de mulheres em tempos de proibição: o caso das partidas Vespasiano x Oficina (1968)
Authors: Ribeiro Raphael Rajão
Published: July 2018

O presente artigo investiga a promoção de uma série de jogos entre duas equipes femininas, Vespasiano e Oficina. As partidas se realizaram na pequena cidade de Vespasiano, vizinha à capital mineira Belo Horizonte, no ano de 1968. Ocorridas em um momento de aprofundamento da proibição da prática do futebol por mulheres no Brasil, que fora vedado expressamente pelo Conselho Nacional de Desportos em 1965, essas disputas articulam-se à mobilização comunitária em favor de uma escola local, bem como à cultura esportiva do lugar. Trata-se de episódio pouco conhecido que ajuda a compreender as formas de organização dessa modalidade, os mecanismos de perseguição a ela e os apagamentos acerca da memória sobre o desempenho dessa atividade atlética por garotas.
Campos, festas e pedreiras: narrativas varzeanas das periferias de São Paulo (SP)
Authors: Spaggiari Enrico
Published: July 2018

Nesse artigo, a questão temporal se revela fundamental para compreender os sentidos que o futebol varzeano desperta nas memórias dos moradores de um bairro periférico da cidade de São Paulo. As narrativas revelam uma contínua reelaboração das percepções de um passado rememorado – do que “era” o futebol de várzea – frente às vivências e transformações do presente. Construídas por diversos atores vinculados ao futebol varzeano, em ritmos temporais marcados por rupturas e lacunas, tais depoimentos e memórias escudam a proposta de uma etnografia da duração, que articula a rememoração de eventos e percepções do passado às reflexões e experiências vividas pelos citadinos no presente, no tempo da interação etnográfica, para impulsionar a compreensão de narrativas biográficas e processos sociais.
Futebol profissional: saída da pobreza? / Professional football: a way out of poverty?
Authors: Heller Mandel Carlos , Burgos Pimentel dos Santos Fernando
Published: July 2018

A pesquisa pretende analisar se o futebol é uma alternativa de saída da pobreza. Com base no trabalho de Fields (2001), Bradshaw (2007), Goldthorpe (2011), entre outros, são discutidos os conceitos de pobreza e mobilidade social. O trabalho de campo pautou-se nas obras de May (2004), Spink (2008) e Rego e Pinzani (2013). Foi possível perceber que é necessário grande investimento familiar para que um jovem participe de uma peneira e que, quando é de baixa renda, há uma relação predatória dos empresários. Diversas barreiras impedem que um adolescente pobre supere sua condição por meio desta prática esportiva. Entretanto, o futebol se configura como uma oportunidade para jovens no que tange a mobilidade social, embora a carreira apresente mais desafios do que a concepção vendida pelos clubes. This research aims to analyze whether football is an alternative way out of poverty. Based on the work of Fields (2001), Bradshaw (2007), Goldthorpe (2011), among others, the concepts of poverty and social mobility are discussed. The field work was based on the works of May (2004), Spink (2008) and Rego and Pinzani (2013). It was possible to realize that, for an adolescent to participate in a try-out, it is necessary a huge investment from his family and that there is a predatory relation of agents with poor teenagers. Several barriers prevent a poor teenager from overcoming his condition through this professional sporting practice. However, football is an opportunity for young people in terms of social mobility, although the career presents more challenges than the idea sold by the clubs.

Os anos 2010 estão marcando uma nova virada histórica nas formas de associação clubística, após um período de intensos debates e transformações de inserção do Brasil na lógica do futebol-negócio a nível global. Este artigo segue uma trajetória de estudos no âmbito de uma Economia Política do Futebol com o objetivo de apontar alguns elementos dentro das mudanças ocorridas nas formas de associações nos clubes brasileiros e como esse tema nos permite compreender a formação política dessas instituições. Para tanto, além do resgate histórico, também buscaremos traçar paralelos com outros países, a fim de preparar o terreno para discutir sobre o momento atual, demarcado pela resistência de grupos de torcedores frente às “vantagens” meramente consumistas.
EVALUATION OF BIOGENIC LIMESTONES FROM HERETHIANA AREA IN WESTERN CRETE FOR HYDRAULIC LIME PRODUCTION
Authors: Μαρκόπουλος Θ. , Τριανταφύλλου Γ. , Μανούσογλου Ε.
Published: July 2018

Biogenic limestones from the area of Herethiana, Western Crete, have been examined in order to evaluate their properties as hydraulic lime raw materials. Samples of three different horizons, X1, X2, and X3 have been investigated using X -ray diffraction (XRD), X - ray fluorescence spectroscopy (XRF), optical and scanning electron microscopy (SEM) and calcimetry analyses. According to the XRD analyses the main component is calcite variying between 80% and 84%. Illite, quartz, albite and goethite are also present in minor amounts. Representative samples, with a particular grain size of the different horizons, were burned at 900°C for 12 hours, to produce hydraulic lime. The analysis of the calcined products showed that larnite, portlandite and lime appear in all samples. Quartz and hematite are also present in minor amounts. The abundance of amorphous silica in the form of silica sponges and diatoms offers the necessary active silica to form, together with an appropriate portion of free lime, the calcium-silicate phase, which is present in all samples in adequate percentages. According to the European standards of the building limes the calcined products of the materials of the three different horizons can be classified as feebly, moderate and eminently hydraulic limes

Published: July 2018

In this paper the suitability of Kozani's broader area carbonate formations for certain applications is studied based on their mineralogical, chemical and technological characteristics. The studied formations geotectoniccally belong to the Pelagonian zone and are represented mainly by pure limestones with few occurences of dolomites and dolomitic limestones. The studied samples represent: a) the Vermion section (formations Be and Bd), b) the Kozani section (formations Be and Bd), c) the Siatista section (formations S1 and S2) and d) the Vouhnos section (formations Bo1, Bo2 and Bo3). The insoluble residue, the organic matter, the whiteness and the mineralogical and chemical composition are studied in order to investigate the suitability of the studied carbonates for specific industrial applications. The results showed that the dolomitic formation of Vermion (Bd) is suitable for the manufacture of flat glass, while the limestone formations of Siatista (S2) and Vourinos (Bo1) as well as the dolomitic formation of Vermion (Bd) are suitable for the manufacture of container glass. The limestone formations of Siatista (S1, S2) and the dolomitic formations of Vermion (Bd) and Kozani (Kd) can be used as fluxes in the metallurgical blast furnace to produce a slag with the acid components of the ore, while the limestone formations of Siatista (S1, S2), Kozani (Kc) and Vourinos (Bo1, Bo2, Bo3) as well as the dolomitic formations of Vermion (Bd) and Kozani (Kd) are suitable for the sinter blasts. Finally, only the S2 limestone formation of Siatista can be used in the desulphurising of flue gas, as it fulfills the chemical specifications and the restrictions in whiteness.

Authors: Σικαλίδης Κ. , Καραγιαννίδης Ν.
Published: July 2018

Limestone, dolomitic stone, huntite, active magnesia and their mixtures as well as phosphorus containing gypsum, all by-products of various industrial activities, were investigated as soil amendments for acidic (pH 4.2 - 4.5) soils from Drama area, N. Greece and alkaline (pH 8.1 - 8.2) soils from Thermi area, N. Greece. Additions of 500 and 350 kg of the industrial by-products or their various mixtures tested, per 1000 sq.meters, improve the soil pH from the strong acidic area to 6.5- 7.5. Active magnesia increases the pH values above 8. Additions of 200 kg of mixtures of limestone and active magnesia per 1000 sq.meters, found to be able to increase the soil pH from 4.2 to around 6.5. These results were obtained within ten days from the day of application. Phosphorous containing gypsum, by-product of phosphoric fertilizers industry, was found to be able to decrease the soil pH from 8.1-8.2 down to 7.1. The results of this work suggest the possible use of the studied by-products as soil amendments for acidic and alkaline soils, respectively.
MlNERALOGICAL STUDY AND PROPERTIES OF MAGNESIA REFRACTORIES DERIVED FROM EVIAN MAGNESITE
Authors: Lampropoulou P. , Katagas C.
Published: July 2018

In order for the Greek magnesia industry to retain a high position in the world market, the basic refractories derived from Greek magnesite must remain at the forefront of the international developments. A mineralogical study of magnesia materials produced from Evian magnesite has been carried out with the aim a) to provide detailed characterization of products and microstructures derived from the firing processes of magnesia raw materials and b) to contribute to the development of new magnesia-spinel refractory materials from natural Greek magnesite. The magnesite of N. Evia, Greece, is micro- crystalline and has been used for the production of basic refractories because of the very low amounts of impurities such as CaO, S1O2, FeO(tot), B2O3 it contains . Magnesia materials studied here are: 1) Raw materials. The dead- burned magnesia grains examined are divided into two groups according to the mode of beneficiation of the raw magnesite: a) Dead burned magnesias produced from natural microcrystalline magnesite (Group A). b) Dead burned magnesias of high purity produced from natural microcrystalline magnesite (Group B). The chemical composition of these materials lies essentially in the MgO-CaO-SiC>2 system, since they contain only trace amounts of Fe2Û3 and AI2O3. Their microstructures vary widely in terms of proportions of direct MgO-MgO bonding, amounts and types of phases of the siliceous bonding and size of the periclase crystals. Dead burned magnesias of high purity are better sintered and contain lower amounts of secondary phases compared to magnesias of lower purity. 2) Commercial magnesia bricks derived from dead burned magnesia of high purity and magnesia chromite bricks derived from raw materials of dead burned magnesia of high purity and chromite from Africa. 3) New spinel-based composition and new magnesia-spinel refractory materials which have been synthesized for the needs of this study. The newly synthesized spinel-based composition (70wt% Al2O3-30wt% MgO) shows an increase in the bulk density as well as in the amount of spinel formed compared to available commercial qualities (50%wt AI2O3). 4) Using this new spinel-based composition and dead burned magnesia of high purity, two new magnesia-spinel refractory materials containing 10 and 20wt% AI2O3 were produced, with the aim to obtain more friendly to the environment magnesia refractories to substitute for the magnesia chromite bricks. The compositions of the magnesia spinel refractories thus produced were expected to show endurance in thermal shocks as well as in the corrosion from slags and friction, in order to have a wide application in steel, cement industry etc .
HYDROGEOCHEMICAL CONDITION OF THE PIKROLIMNI LAKE (KILKIS GREECE)
Authors: Dotsika E. , Maniatis Y. , Tzavidopoulos E. , Poutoukis D. , Albanakis K.
Published: July 2018

In order to understand the hydrogeochemical conditions of the basin of Pikrolimni we collected water samples from the borehole in the thermal spa of Pikrolimni and samples of brine and sediments from the lake. We also sampled fresh water of the region. The depth of the borehole in the thermal spa is approximately 250 meters. This water is naturally sparkling, with a metallic aftertaste and a slight organic smell. The samples were taken twice during the year: in summer (8/2002) and in winter (2003). The analytical scheme includes field measurements of temperature, conductivity and pH. Major ions (Na+, K+, Ca2+, Mg2\ CI", Br, S04 2", C03 2", HC03", N03"), F and Br were determined, in laboratory, according to standard analytical methods. Samples were also subjected to isotopie analysis of δ Ο and δ2Η. The results from the chemical analyses of the samples, show that the waters taken from the borehole, are of the type Mg- (Na-Ca)-HCC>3 and the salts of the lake are of the type Na-CI- (CO3-S04). The salts of the lake result from mixing and condensation of the waters which are accumulated in the basin of the lake, and come not only from sources that feed the lake, e.g. waters from borehole, but also from rain water. The waters of these sources are mainly of meteoritic origin and circulate deeply, mixing probably with salt water of deeper and probably of warmer horizons. The latter comes in agreement with the hydrothermal field, which exists in the area. From hydrochemical data, the brines of summer clearly correspond to waters, which have been submitted under high degree of evaporation: they are residual mother solutions before the step of the precipitation of halite. During winter, dilution of brines and dissolution of depositing minerals by fresh water are observed. On the other hand, evaporating conditions are created in the lake during summer.

Published: July 2018

The olive oil production countries are currently faced with the major problem of dealing with olive oil mill wastewater. Effective treatment of these organic liquid wastes (katsigaros) has not been proposed yet. The common practice followed the last fifteen years in the island of Crete includes the creation of open wastewater evaporation ponds. The present work studies the sorption of organic agents, more specifically the phenolic compounds, in various lithology rocks. Three different samples were tested including Neogene marl-calcareous marl from Platania/Kissamou (PLA) area, schistolithic rock from Sarakina/Selinou (SAR) area and Neogene marl-siliceous (diatomite) marl successions from Basilies/Heraklion (VAS). The organic liquid wastes affect differently the PH and electrical conductivity from the studied rocks with different mineralogical composition. Rocks containing lllite show a significant adsorption of the phenolic compounds. Similar behavior is observed for the Neogene marl-siliceous (diatomite) samples, while the schistolithic rock show the lowest adsorption. The katsigaros dissolve the calcite and iron minerals and increases the CaO and Fe203 in the liquid waste.
QUATERNARY DEFORMATION OF THE MAVROPIGI LIGNITE FIELD (WESTERN MARGIN OF PTOLEMAIS - KOZANI GRABEN, NW MACEDONIA, GREECE)
Authors: Diamantopoulos A. , Dimitrakopoulos D. , Fountoulis I.
Published: July 2018

The present study aims to analyse in details the tectono-sedimentary processes of the western borderline of the intra-continental graben of Ptolemais-Kozani in NW Macedonia, given the presentday mining activity of Public Power Corporation. Field studies in combination with drilling analysis revealed the extremely geometrical complexity of the sedimentary fill as the result of the recent Quaternary deformation. Bearing in mind, the recognition of left-lateral strike-slip component of movement in the western border fault zone-Mavropigi shear zone, the geometrical coincidence of the morphological shapes of the present-day morphology-of the top-of the bottom of the Pliocene earthy lignite sequence and of the sub-surface morphology of the pre-Cretaceous Pelagonian basement as well as the discovery of several reverse faults in the surrounding area have allowed us to accept the action of a composite Quaternary deformational pattern. For the first time in NW Macedonia, ductile-brittle type macrostructures (mega-anticlines) with NE-SW axis direction are confirmed, showing the simultaneous and progressive action of ductile and brittle deformation of all the geological formations of the western borderline, sedimentary fill and metamorphic basement. The aforementioned geometrical complexity and also the observed field structures strongly reveal the action of a rotational couple-type stress field in Ptolemais-Kozani graben, enclosed in the incapiate in-type deformation of NW Macedonia. In this framework, the occurrence of the extensional post-orogenic structures, which seems that they have been overestimated by previous researchers in the literature, is considered of secondary importance and constitutes part and expression of the complicated Quaternary tectonic structures of the sedimentary fill. This complex deformational pattern controls and also defines the spatial distribution of the lignite reserves in the Mavropigi Lignite Field with a southward increasing of them as well as causes regions with a composite or a simple post-orogenic geometry and evolution, directly reflected by the sub-surface geometry of the Pliocene lignite sequence. The aforementioned complicated geometry is of great importance, either for the planning and the future expansion of the Mavropigi Lignite Field in the western borderline, or for the better approach of the intra-plate deformational processes of Ptolemais-Kozani graben.
MOLECULAR INDICATORS FOR TAXODIUM DUBIUM AS COAL PROGENITOR OF "CHUKUROVO" LIGNITE, BULGARIA
Authors: Stefanova M.
Published: July 2018

The coal sediment under study was of Miocene/Pliocene geological age. The petrological data pointed to Tortonian/Sarmatian age, while the paleobotanical ones - to Middle Miocene. It was documented that "Chukurovo" basin was determined by coal fades indices as limnic ombrotrophic forester swamp. Fossilized trees predominated in "Chukurovo" lignites. Well preserved wood tissue of stems and twigs impregnated by clays and enriched in organic matter were macroscopically observed. Four types of phytocenosis - aquatic, swamp, flood plain, forests, i.e. mesophilous and mesohygrophilous were proposed. The composition of the last one confirmed the predominance of evergreen laurel and laurel-oaks communities during the Miocene. In the present investigation tools of organic geochemistry were applied. Extractable matter from Taxodium dubium (Sternb.) Heer was studied by a sequence of extraction, separation and chromatographic identifications. The molecular data confirmed botanical assignment of the macrofossil to conifer family Taxodiaceae. A lot of identified geolipids, i.e. alkanes, alcohols, fatty acids, and steranes/triterpanes were without chemosystematic value as ubiquitous in plant kingdom. Ferruginol, sugiol, totarol and products of their diagenetic transformations were identified as the dominant biomarkers. Ferruginol and its homologues were the most abundant phenols in Taxodium dubium (Sternb.) Heer. The biomarker composition of extractable matter strongly suggested that species of Cupressaceae /Taxodiaceae contributed in major amounts to "Chukurovo" paleoplant swamp.
HYDROTHERMAL ALTERATION AND MINERALIZATION OF THE PETROTA EPITHERMAL SYSTEMS (W.THRACE, GREECE)
Authors: Μιχαήλ Κ. , Δημήτρουλα Μ.
Published: July 2018

At the Petrota graben important epithermal zones are developed. On the basis of the mineral assemblages of alteration zones and the type of the host rocks, the epithermal zones can be grouped into three epithermal systems: 1. Perama epithermal system 2. Mavrokoryfi epithermal system and 3. Othondoto epithermal system Hydrothermal alteration zones are developed within volcanoclastic rocks - epiclastic sandstones, andésite tuffs (Perama epithermal system), hyaloclastites (Mavrokoryfi) and rhyolitic rocks (Othondoto). Silicification (in various types) and advanced argillic alteration are the most important alteration zones and are established on the largest scale. Ore mineralisation occurs as veins, veinlets in silicification zones or secondary mineralisation in the supergene zone (Perama epithermal system). Disseminated ore mineralization is also found in the silicification zone at Othondoto and Mavrokoryfi epithermal systems. Based on the geological environment, the type of hydrothemal alteration zones (silicification and advanced argillic alteration) and the mineral compositon of the ore (enargite- luzonite), the hydrothermal systems of Petrota graben can be referred as high sulfidation systems.

A new skarn, near Therapio village, in the Evros prefecture, is described in terms of mineralogy and petrogenesis. The skarn is developed in amphibolites in close relation with pegmatite veins. It is constituted of garnet, magnetite and quartz, while retrograde minerals are actinolite, and chlorite, along with sulfides and hematite, some of them also found in the host rock. The mode of skarn growth and its close relation with the pegmatite veins indicate the genetic relation between them. At the same time, the cataclastic structure of the garnets and the magnetite as well as the brittle structures, imply later tectonism. According to the field observations and the results of the laboratory study, the Therapio skarn is a result of the metasomatism due to the intrusion of the pegmatite veins into the protolite amphibolite.

In the broad area of Pentelikon Mountain, which is part of the Attic-Cycladic crystalline belt, metamigmatites and orthogneisses occur as tectonic slices within the calc-schists or between calcschists and marbles. In the metamigmatites relic of migmatitic fabrics, comprising leucosomes and melanosomes, and cross-cutting aplitic and pegmatitic dykes are still preserved. The orthogneisses have dioritic to granitic composition. They are interpreted to be probably formed in a magmatic arc setting. Granitic orthogneisses show high-K contents and are enriched in LILEs and depleted in HFSEs. They also exhibit fractionated REE patterns with slight to strong negative Eu anomaly. The exceptionally high K2O contents (>7%) and the very low Na2Û contents (0.4-0.98 wt%) of certain phengite-orthogneisses with ultramylonitic textures are attributed to metasomatic processes that occurred during ultramylonitization.
CHEVRON-TYPE HALITE AND NODULAR ANHYDRITE IN THE TRIASSIC SUBSURFACE EVAPORITES OF THE IONIAN ZONE (WESTERN GREECE)

Published: July 2018

Samples of the Ionian zone (western Greece) subsurface evaporites, obtained from well cores in salt bodies and in depths ranging from 1000 to 3500m, are texturally studied. Layered halite rocks consisting of chevron-type halite crystals represent most of the specimens. Between the chevron -type halite crystals, which are fluid inclusions-rich, clear halite without inclusions has been diagenetically formed by dissolution and precipitation processes. Anhydrite always accompanies the halite rocks as crystals or nodules. No-occurrence of gypsum has been detected. Along halite grain boundaries dolomite crystals occur. Dolomite grew on halite crystal surfaces as an early diagenetic mineral. Some dolomite crystals are clearly derived by replacement of anhydrite crystals. Halite layers are rich in clay and carbonaceous material favoring reducing environment (presence of pyrite crystals). Chevron-type halite supports accumulation beneath a body of brine, possibly recording annual precipitation cycles. However, its close association with nodular anhydrite cannot exclude the possibility of halite development, in a shallow-water or emergent environment by displacement from capillary brines. Since the studied halite crystals show evidence of mineral replacements and displacement, we suggest an analogous mechanism including accumulation from a standing body of brine and subsequent textural modification in the groundwater zone. Although, Ionian subsurface evaporites have undergone the above-mentioned diagenetical processes, they still reU in their primary textural characteristics. Real brecciation has not been detected in subsurface, except of an in-situ pseudo-brecciation. This observation clearly shows that the outcropping evaporite solution-collapse breccias were formed in the realm of meteoric zone, after the Ionian zone orogenesis.
ORIGIN AND EVOLUTION OF THE OPHIOLITIC COMPLEX OF ZDRALJICA (CENTRAL SERBIA)
Authors: Resimic-Saric K. , Koroneos A. , Cvetkovic V. , Balogh K.
Published: July 2018

The ophiolitic complex of Zdraljica (Central Serbia) belongs to the Eastern Branch of the Vardar suture zone. It was emp'aced during the Upper Jurassic. The complex consists predominately of a MORB/VAB-like tholeiitic suite, represented mostly by gabbros and diabases. Small occurrences of cummulitic peridotites, basalts and plagiogranites also appear. The tholeiitic suite is intruded by calc-alkaline intermediate and acid magmas. Geochemical data suggest that the ZOC tholeiitic rocks originated by partial melting of a spinel-lherzolite source. Non-modal batch melting modeling indicates 10 to 15 % of partial melting of such a source. The magmas were later modified by fractional crystallization. One-step major element modeling requires 40% (F=0.60) of fractional crystallization of a mineral assemblage: PI52 gCpxi2 5OI26 iTtn2 9Ap4.4Mgt1.0- The model is supported by the variation patterns of most trace elements.
Tectonic evolution of the Hellenic Orogen. Geometry and kinematics of deformations
Authors: ΜΟΥΝΤΡΑΚΗΣ Δ.
Published: July 2018

The Hellenic orogen consists of three orogenic belts: 1) the Cimmerian orogenic belt, including Rhodopian, Serbomacedonian, Circum Rhodope, Axios and Pelagonian zones, is the internal belt which has been created in pre-Late Jurassic times as a result of the northward drift of Cimmerian contrinental fragments from Gondwana towards Eurasia. Ophiolites from small ocean basins were mainly emplaced onto the Cimmerian continental margins in Middle Jurassic. 2) the Alpine orogenic belt, including External Hellenides and Pindos-Subpelagonian ophiolites and oceanic sediments (Neo-Tethyan), which has been created in Cretaceous-Paleogene times after the subduction of the Neotethyan oceanic crust beneath the Cimmerian-Eurasian plate and the collision of the Apulian microplate to the later, 3) the Mesogean orogenic belt along the External Hellenic orogenic arc as a result of the Mesogean-African underplate beneath the unique Alpine-Cimmerian-Eurasian plate in Miocen- Pliocene times and the exhumation of the Cretan-Southern Peloponesus tectonic windows. Structural analysis and detailed studies of the geometry and kinematics suggest that during Alpine-Mesogean orogenic process a SW-ward migration of successive complessional and extensional tectonic events took place resulted of successive subductions. Thus, crustal thickening produced by compressional tectonics in each area was followed by an extensional exhumation of underplate rocks as tectonic windows.

The Geological study of the sea bottom and subbotom and the recent research trends (with emphasis on the continental shelf area)
Authors: ΠΕΡΙΣΟΡΑΤΗΣ Κ.
Published: July 2018

The systematic research of the sea bottom started axcually only in the 19th century with the research voyage of the British ship "CHALLENGER" but was particularly developed during the early 20th century. The Greek seas were geologically explored after 1950, with the research trip of the R/V Verna in 1954 in Korinthiakos Gulf. Since then a great number of research programs has been carried out in the Greek Seas both in the shelf and the deep sectors in which the Greek scientists have played a major role. The major factor in shaping the todays shelf morphology is sedimentation controlled mainly by the sea level changes during Quaternary. The shelf break in the Aegean and Ionian seas lies at a depth of 120m. to 160m. and is usually covered by relict sediments and locally by holocenic sediments, particularly at the deltaic areas. In low sea level stands many of the todays gulfs were subaerically exposed or constituted lakes of variable depth with or without outlets toward the open sea. During these stages coarse sediments were deposited mainly beyond the shelf break. During high sea level stages the coarse sediments were deposited on the shelf and the fine grained ones surpassing the self break were deposited in the deep areas. Theses changes in sediment texture are reflected in the deep sea seismic profiles as alternating opaque-transparent layers. Although the Greek area is characterized by high seismic and tectonic activity, tectonism and eustatic/isostatic factors played a considerably minor role in shaping the shelf morphology that of sea level changes. The study of the shelf area during the various sea level stands helped in locating occurrence of placer deposits in the Northern Aegean shelf and in recognizing the trans gressional layer as a suitable horizon for foundation of civil engineering projects. Except these, the shelf studies contributed important information to the basic geological knowledge. Examples from condribution to geoarchaeology to biogeography are cited. Regarding the future research trends in Marine Geology, these can be: The development of marine data (metadata) bases. The systematic use of multibean systems. The further development of digital processing of the seismic reflection records. The collection of data for the anticipating future climatic changes. The assessment of the eventual catastrophic events in the coastal zone. The recording in real time of the active sedimentation parameters.

GENTRIFICAÇÃO: ASPECTOS CONCEITUAIS E PRÁTICOS DE SUA VERIFICAÇÃO NO BRASIL
Authors: Ribeiro Tarcyla Fidalgo
Published: July 2018

Muito tem se falado, especialmente nos últimos anos, sobre gentrificação no Brasil. O termo parece ter se tornado lugar comum entre estudiosos do urbano e por vezes parece ser utilizado sem muito rigor científico, para referência a fenômenos distintos ocorridos em áreas alvo de políticas públicas de redesenvolvimento ou incremento de infraestrutura urbana. No entanto, os contornos do conceito de gentrificação e a problematização de sua aplicação no cenário urbano brasileiro são pouco explorados nos textos sobre o tema, o que vem permitindo um certo grau de distorção do conceito e dos fenômenos a ele submetidos. O presente artigo pretende ocupar esta lacuna ao realizar um estudo conceitual mais detalhado e uma problematização do cenário geral da aplicação do conceito de gentrificação, passando por um breve panorama latino americano e chegando ao Brasil a partir da análise de algumas experiências em cidades brasileiras, para então concluir sobre os limites e potencialidades do conceito na realidade nacional. A metodologia utilizada se baseia em análise bibliográfica e empírica a partir de dados obtidos de forma indireta.
CIDADANIA DO MERCOSUL E AGENDA DE TRABALHO DECENTE NO BRASIL: REVISÃO DAS CONDIÇÕES DE VIDA E EMPREGO DOS ANDINOS RESIDENTE NO RIO DE JANEIRO
Authors: Desiderio Edilma De Jesus
Published: July 2018

A população residente do Mercosul conta com reconhecimento da cidadania regional, regido por normas relacionadas com o exercício do direito a estudar, viajar, trabalhar e residir nos países partes. O objetivo desta reflexão é examinar as condições vida e trabalho da população mercosulina, procedentes dos países andinos no Brasil, relacionadas com a proteção social e apegadas a Agenda de Trabalho Decente. O marco teórico relacional e situacional se fundamenta na produção do espaço de direitos sociais e trabalhistas assimétricos. A metodologia explora a construção da mobilidade populacional no Mercosul e a informação disponível no Censo Demográfico 2000 e 2010, especificamente, relacionada com os indicadores de Trabalho Decente da OIT. Os resultados encontrados refletem uma heterogeneidade de formas de inserção laboral para o grupo de andinos e, ao mesmo tempo, uma desigualdade em matéria de oportunidades, remuneração equitativa e garantia de direitos trabalhistas, permitindo uma aproximação às representações espaciais concebidas para esta população. Como considerações finais, efetivamente, encontra-se mais avançado uma construção de identidade regional que uma cidadania plena, demonstrando assim, uma realidade similar às condições que enfrenta as populações estrangeiras ao ingressar nos mercados de trabalho brasileiro e, por tanto, limitante ao exercício de uma proteção social inclusiva e integral.Palavras-chave: Migração.
