COMPARATIVE STABLE ISOTOPES STUDY OF THE MAGNESITE DEPOSITS OF GREECE
Authors: Gartzos E.
Published: July 2018

The magnesite deposits of North Evia, Lesvos and Chalkidiki, which are hosted by Alpine type ultramafic rocks, have been studied from an isotopie point of view and are compared with similar magnesite deposits occurring in other countries of central-southeastern Europe and Turkey. Magnesites from N. Evia, Lesvos and Chalkidiki have similar isotopie compositions. They have 513CPDB values ranging from -8.6 %o to -14.8 %o and 518OSMOW values ranging from 24.0 %oto 30.1 %o, which indicate a rather similar formation process for all three areas. The studied Greek magnesite deposits have similar isotopie compositions with vein and stockwork type magnesite deposits from: Turkey (Koyakci Tepe, vein and stockwork types; Helvacibaba, stockwork type), Poland (vein type), and Former Yugoslavia (vein type). There is strong isotopie evidence that meteoric water is involved in the formation of the stockwork and vein type magnesite deposits of all four countries, including Greece. There is also isotopie evidence for the organic origin of carbon participating in the carbonates (magnesites) of these deposits.

Published: July 2018

The excavation of the hard formations of the overburden is one of the main problems of lignite exploitation in Southern Field Mine of Western Macedonian Lignite Center. These hard formations consist of sandstones, conglomerates and silts. Since their excavation is difficult with bucket wheel excavators, blasting and diesel equipment is used. These formations have been deposited in three different geological periods and can be described according to their colour in red, yellow and green series. Red strata contains 38% of hard formations, the yellow strata contains 49% hard formations and the green strata contains 2%. The total content of the overburden in hard rocks is 26.2%.

The aim of this study is to estimate the environmental impacts in case of exploitation the Pellanalignites for power generation. The object of the study is to predict the element mobility during lignite combustion using mineralogical and geochemical data from bulk-lignite samples and their ashes of two cores from this area. The mineralogical determinations on the ashes revealed that quartz, K-feldspars and illitemicas are the major mineral phases contained in the lignite. The identification of anhydrite in ashes implies the presence of gypsum, althought neoformation of anhydrite from organic associated with Ca+2 and SO42 can not be excluded. These minerals correspond to primary phases. Oxides and hydroxides occur subordinately and probably represent minerals that do not correspond to primary phases. The results of the elemental analysis show that the major elements (>1000 ppm) are AI, Fe, Ca, Mg and Κ in the bulk samples of both cores. Minor elements (100-1000 ppm) are Na, Mn and Ba, while the concentrations of Be, Bi, Cd, Ce, Co, Cs, Cu, Eu, Ga, Hf, La, Li, Lu, Mo, Nb, Nd, Pb, Rb, Sb, Se, Sm, Sn, Sr, Tb, Te, Th, TI, U, Y, Yb and Zr do not exceed 100 ppm. The concentrations of many elements like As, Ba, Cr, Ni, V and Zn have a wide range among the bulk samples. In order to assess the geochemical affiliation of the studied elements, R-type factor analysis was applied on the element contents of bulk lignite and ash. The elements Ca, S, V, As, Μη, Mo, Na, Sb, Hf, Zr and U provide both organic and inorganic affiliations, while Se and Nb provide organic affiliations. To approach the mobility of each trace element, the relative enrichment factor (RE) was calculated. The most depleted trace elements according to RE mean (<0.5) are Hf and Sb, while the elements Se and Ba are moderately depleted (0.7>RE mean>0.5).
EXPLOITATION OF GOLD ORES DEPOSITS. THE PRESS AND THE LOCAL SOCIETY, ENVIRONMENTAL PROTECTION AND CONCERN. THE CASE OF THRACE REGION (GREECE).

Published: July 2018

The proposed possible exploitation of gold ores deposits in the region of Thrace introduces a number of issues regarding the protection of the environment and the relevant concerns, set by the local communities, the information which the society is receiving on such matters through the press, and the presentation of such industrial activities through out the press. In this paper, a number of articles published in national and local press, dealing with the above issues are examined. At the same time, this work presents the results of a survey which was contacted in the region in order to investigate the perception of the local community, and the influence of the press in shaping the local public opinion with respect to a possible exploitation of the gold ores deposits in Thrace.
MlNERALOGICAL STUDY OF BISMUTH - GOLD - ANTIMONY MINERALIZATION AT THE AREA OF KAMARIZA, LAVRION
Authors: Σολωμός Χ. , Βουδούρης Π. , Κατερινόπουλος Α.
Published: July 2018

At the Lavrion mine, area, near the village of Kamariza, an oxidized mineralization unusually rich in bismuth, gold, antimony and copper has been studied. Three different parageneses have been recognized and described: a) a copper-rich assemblage, containing chalcopyrite, chalcocine, digenite, covelline, azurite, malachite and georgeite, b) a bismuth-gold-rich assemblage, consisting of native bismuth, bismuthinite, native gold, bismite, bismutite, beyerite, kettnerite, preisingerite, rooseveltite and mixité and c) an antimony-rich one, comprising stibiconite, bindheimite, mimetite and gartrellite. The mineral study suggests that the primary mineralization should consist of pyrite ± arsenopyrite, chalcopyrite, bismuthinite (and/or bismuth sulphosalts), native bismuth, maldonite (which has been exsoluted to gold and bismuth) and bournonite. The oxidation of this primary mineralization and the reac ion with supergene solutions containing significant amounts of HCO3" and HAsCV2 - H2ASO4", caused the formation of 17 secondary minerals.
MlNERALOGICAL STUDY OF Mg-SKARNS WITH CLINOHUMITE AT THE OMERLI SITE AGGISTRO, SERRES
Authors: Δήμου Ε. , Κούκουζας Κ.
Published: July 2018

Mg-skam occurrences located in the dolomitic marbles at the Omerli site near Aggistro are studied. The dolomitic marbles are gradually enriched in metasomatic minerals, up to the full replacement and the formation of cohesive lenticular beds of skarns in the marbles. The aplito-pegmatitic veins traversing the surrounding marbles as well as the granodiorite occurring in the broader area of Ahladohoho, are considered responsible for the phenomena of thermal metamorphism and metasomatism in the dolomites. On the basis of mineralogical analytical methods (optical microscopy, X-Ray diffraction, microanalysis) the following metasomatic minerals in decreasing order, have been determined: Clinohumite (Mg, Fe +)Q (Si04)4(F,OH)2, forsterite Mg2Si04, spinel MgAb04, hornblende-pargasite NaCa2 (MgFe% AI(SÌ6AI2)022(F,OH)2, clinochlore (MgFe2+)AI(SÌ3AI)Oi0(OH)8, phlogopite KMg3SÌ3AIOio(F, OH)2, dolomite, calcite. The mineral chemistry and petrography of the above assemblages lead to the conclusion that the skarns at Omerli site constitute pure metasomatic concentrations at the expense of the dolomites, with addition of elements from external thermal source and removal of elements from the hosting dolomites. It is, therefore, an open chemical system and not an iso-chemical one.

Published: July 2018

Standard mixtures of amorphous material (volcanic glass) and crystalline phase (equally participated montmorillonite, muscovite, heulandite, quartz, and calcite) were prepared at the following weight proportions after weighting: 100-0, 75-25, 50-50, 25-75 and 0-100, respectively. From their XRD patterns and using two different techniques of analysis the percentage of amorphous material was calculated. The pure amorphous and crystalline standard mixtures constituted the mixtures of report. The area of the broad background peak of the amorphous material determined using the analogical technique and its percentage was calculated by comparing the measured area to the area of the 100:0 standard mixture, while with the second technique was appreciated the crystallinity of each standard mixture and from this resulted the percentage of amorphous material. It was found that between the two methods there is a very good identification and their divergence concerning the weighed percentages varied between ±3 wt. %. The percentage proportion of minerals based in the values resulted from the application of mass absorption coefficient is in very good agreement with the weighted proportions. The method of Powder X-Ray Diffraction can constitute a very good tool for the semi-quantitative calculation of the amorphous material contained in a sample.
PLUMBIAN "ALUNITES" IN HYDROTHERMAL ALTERATION ZONES OF EPITHERMAL AND PORPHYRY TYPE MINERALIZATIONS IN W. THRACE
Authors: Βουδούρης Π. , Αρίκας Κ. , Κατερινόπουλος Α.
Published: July 2018

In this study a new occurrence of Pb-rich members of the alunite supergroup minerals is described. The "alunites" were traced in advanced argilic alteration zones of epithermal and porphyry type mineralizations in W. Thrace/(Greece). These "alunites" are Ca-Sr-Ba-Pb-rich phosphatessulfates and represent solid solutions between members of the alunite, woodhouseite and crandallite group minerals. The highest concentrations of PbO in the Mavrokoryfi and Melitaina alunites are 24.7% and 17.4% respectively. The plumbian phosphates-sulfates occur in the cores of the crystals and are surrounded by common K-Na-rich alunites in Mavrokoryfi and Ba-rich woodhouseite in Melitena, an indication that they were formed in a magmatic-hydrothermal environment after dissolution of apatite and feldspars by phosphate-sulphate rich solutions. The mineral-chemistry of these "alunites" can provide information regarding the genesis of the advanced argilic alteration zones in Greece, and help us in the distinction of the epithermal from deep porphyry style environments.
GEOCHEMICAL CHARACTERISTICS OF PIGI AND KARATHODORO MIGMATIZED METASEDIMENTS, GUEVGUELI COMPLEX, MACEDONIA, GREECE
Authors: Ζαχαριάδου Σ. , Σολδάτος Τ. , Δημητριάδης Σ.
Published: July 2018

Two continental slivers, those of Pigi and Karathodoro (parts of the Stip-Axios unit) are intercalated among members of the Guevgueli ophiolitic complex. These two slivers are closely related with the Late Jurassic basic and acid (expressed mainly by Fanos granite) magmatism ofthat area. A subduction-related volcanic suite intrudes the two continental slivers. Migmatized metasediments constitute the main lithological type of Pigi and Karathodoro. The geochemistry shows that minerals participating in the main decompressional-melting reactions, such as biotite, sillimanite, cordierite, plagioclase and orthoclase, control the differentation of the major elements between mesosomes - diatexites, leucosomes and restites. The refractory behavior of accessory minerals, such as monazite, allanite, zircon, hercynite and ilmenite, control the differentiation of the trace elements. Harker and rare earth element diagrams establish a complementary relationship between restites, leucosomes and mesosomes. In the peraluminous system Ab-Qz-Or leucosomes are projected close to the thermal minimum between 760-800 °C. A main exception is the Platania granite projected within the quartz stability field, probably due to the participation of restitic quartz in its mineralogy. The geochemical results are in good agreement with the pétrographie observations and show that the partial melting was responsible for the formation of Pigi and Karathodoro migmatites

Published: July 2018

The myddy formations studied are characterized by the presence of abundant friable aggregates. Lithologically they belong to the sandy muds up to muddy sands. As their grain size decreases the percentage of the clay minerals increases significantly. Among the clay minerals illite predominates, while smectite, vermiculite, chlorite, kaolinite and their interstratified phases, follow. The presence of amphiboles and pyroxenes, as well as the high content of clay minerals and feldspars in these muddy formations, signify their mineralogical immaturity and the predominance of mild climatic conditions and thus mild weathering processes. The compaction and induration degree of the studied sediments is medium, because of the presence of grains of various granulometrie and mineralogical composition. Their swelling and shrinkage grade is relative high, because of the high content of smectite and its interstratified phases.
NEW EVIDENCES OF THE LOW-P/HIGH-T PRE-ALPINE METAMORPHISM AND MEDIUM-P ALPINE OVERPRINT OF THE PELAGONIAN ZONE DOCUMENTED IN METAPELITES AND ORTHOGNEISSES FROM THE VORAS MASSIF, MACEDONIA, NORTHERN GREECE
Authors: Mposkos E. , Krone A.
Published: July 2018

Pelitic rocks of the pre-Alpine "gneiss series" from the Voras Massif record a polymetamorphic history of three metamorphic events; a first HT event indicated by migmatitization phenomena, a subsequent LP-HT event (andalusite-sillimanite series) at 2.5-3 Kbar and 610-640°C, and a third medium-P event at ~11 Kbar and ~550°C. The LP-HT metamorphism is associated with intrusion of Variscan granitoid plutois in a magmatic arc setting. The medium-P metamorphism records an Alpine event (probably Early Cretaceous) indicated by kyanite, chlohtoid, garnet and staurolite formation replacing andalusite and cordierite. The Variscan granitoids and the overlying lithologies of the "schist series" are affected only by the medium-P metamorphism. Granitoids are transformed into phengite orthogneisses having the mineral assemblage phen (Si=3.35-3.47 a.p.f.u.)±Bt-Ab-Kfs- Qtz±Czo±Grt and high-alumina pelites into gamet-chloritoid schists with the mineral assemblage Grt-Ctd-Chl-Ms-Qtz-Rt±llm. The "schist series" which underlies the Late Triassic-Early Jurassic marbles and overlies lithologies of the "gneiss series" and metagranitoids represents protoliths of the Permo-Triassic volcanosedimentary series deposited at the eastern margin of the Pelagonian continental block
COMPARATIVE GEOCHEMICAL STUDY OF THE TRIASSIC TRACHYANDESITES OF GLYKOMILIA AND ALKALI BASALTS FROM THE KOZIAKAS OPHIOLITE MELANGE (W. THESSALY): IMPLICATIONS FOR THEIR ORIGIN
Authors: Pomonis P. , Tsikouras V. , Hatzipanagiotou K.
Published: July 2018

The Triassic Glykomilia trachyandesites of the Koziakas mountain range (western Thessaly) are parts of the oldest volcanic series in continental central Greece. Rock fragments and blocks of pillowed alkali basalts, which are dispersed into the Koziakas ophiolite mélange, display similar subparallel chondrite-norme'ized trace and rare earth element patterns to the trachyandesites, suggesting cogenetic origin. However, the Glykomilia trachyandesites are more differentiated than the Koziakas alkali basalts, which display a different petrogenetic evolution from the basalts occurring in the Koziakas Ophiolite Unit. REE patterns and discrimination diagram plots reveal significant similarities to Triassic volcanic rocks from the Hellenides, suggesting also a VAB signature for the Glykomilia trachyandesites and a WPB affinity for the alkali basalts. Partial melting of a LILEenriched hydrous mantle under spreading conditions is suggested to give rise to Glykomilia trachyandesites. This partial melting episode was probably induced by the uplift of an OIB-type mantle plume, which subsequently produced the WPB alkali basalts of the Koziakas ophiolite mélange. The close association cf both the Glykomilia trachyandesites and the Koziakas alkali basalts with cherts lead to the hypothesis of eruption in a deep rift basin.
Magmatic emplacement of northwestern Geece ophiolites

Published: July 2018

New field observations reinforce the interpretation that was admitted from 1956 to 1970 according to which the ophiolites of Northwestern Greece were generated and emplaced as a massive submarine flow of mantelle magma which had risen through the opening of an orogenic rift. As it opened, the still narrow rift left out submarin tuffs and lavas (pillows) which have been found in different places under the basal peridotites of ophiolitic suits.

Petrology of the ultra-high pressure metamorphic Kimi complex in Rhodope (NE Greece). A new insight into the Alpine geodynamic evolution of Rhodope
Authors: MPOSKOS E.
Published: July 2018

Structural, penological and geochronological work has revealed that the Rhodope metamorphic province is a synmetamorphic nappe-system of Alpine age. The Kimi complex representing the uppermost entity underwent UHP metamorphism in Lower Cretaceous (>119 Ma). Diamond inclusions in garnet porphyroblasts, exsolutions of quartz rods and rutile needles in garnet from Grt-Ky-Bt-gneisses constrain pressures >4 GPa (probably -7 GPa) and temperatures > 1000 °C, indicating subduction of continental crust into the asthenospheric mantle. The garnet-spinel peridotite of the Kimi area represents a segment of upwelling asthenosphere reequilibrated into the lithospheric mantle wedge at -2.5 GPa and 1235 °C. The spinel-garnet clinopyroxenites, associated with the peridotite, represent HP mantle cumulates crystallized from a melt at similar P-T conditions (i.e. P-2.4 GPa, T~1200°C). Decompression and cooling took place in the mantle wedge within the Cr-Spinel peridotite field up to -1.8 GPa and 900 °C. Subsequent isobaric cooling crossed the stability field of garnet peridotite. At this stage, the peridotite was tectonically emplaced into the educted underlying continental crust. Three stages of exhumation of the crustal assemblage occurred in the Kimi Complex. The first stage, from the maximum depth of -200- 220 Km to -60 Km (P-1.6 GPa, T-800 °C), is characterized by slow cooling rates, indicating rapid exhumation. The second stage, from -60 Km to -38 Km (P-1.05 GPa, T~640°C), is indicated by cooling at slow rates and is characterized by hydration and annealing reequilibration/recrystallization processes. The third stage of exhumation started between 73 and 65 Ma and is characterized by rapid uplift, continuous influx of water, intrusion of muscovite pegmatites at -20 Km depth, and finally by rapid cooling at shallow levels. The Kimi Complex reached the surface before 48-42 Ma.
Geodynamics and evolution of the Miocene mineralization in the Cycladic - Pelagonian belt, Hellenides
Authors: SKARPELIS N.
Published: July 2018

The paper aims to provide a sound account of the type of Miocene mineralisations in the Cycladic – Pelagonian belt and their relationship with the geodynamic evolution of the area. Skarn and manto types, epithermal precious and base metals mineralisation, and vein magnesite in ultramafics are associated to distinct stages of the geodynamic evolution of the belt. Extensional tectonics favoured their generation. Late stages of extensional tectonics resulted in the formation of vertical to subvertical NW-SE trending fault zones, which were then used as conduits for ascending hydrothermal fluids. The relationship between the geodynamics and the metallogenetic evolution of the belt is discussed on the basis of available data on the geology of four critical areas: Tinos and Mykonos islands, Laurium and Northern Euboea.

O Estatuto da Metrópole, como novo marco legislativo de uma realidade regional então reconhecida apenas de forma socioeconômica - e ora prevista normativamente - reconfigurou o conceito legal da dinâmica da governança interfederativa e da gestão plena de Regiões Metropolitanas e Aglomerações Urbanas. Como decorrência, espera-se que o pacto federativo, na forma como originariamente conhecido, deverá também ser revisitado no tocante à cooperação que se espera entre os entes federados integrantes desta nova realidade. Mesmo que Regiões Metropolitanas e Aglomerações Urbanas não sejam efetivamente entes federados formais, deverão gerir os interesses comuns dos Municípios componentes de forma harmônica com o exercício de suas competências legislativas e administrativas, de acordo com os instrumentos de desenvolvimento urbano integrado previstos no Estatuto da Metrópole. Um deles é a Parceria Público-Privada Interfederativa, que carece de valor conceitual claro, o que não se afere diretamente a partir da legislação, mas deve ser interpretado de acordo com o regime das competências administrativas e legislativas que decorrem do pacto federativo, o que constitui o objetivo deste artigo. Como método para conferir o sentido pretendido foi realizada revisão bibliográfica, buscando considerações à luz do pacto federativo brasileiro que pretende, mas ainda não o é, cooperativo.

Published: July 2018

O presente estudo versa sobre o necessário enfrentamento da crise socioambiental decorrente da má gestão dos resíduos sólidos, levando em conta os termos da Lei da Política Nacional de Resíduos Sólidos. Utilizou-se do método indutivo para realização de pesquisa bibliográfica e de dados estatísticos, no intuito de demonstrar que o cerne do impasse a ser suplantado - de produção desenfreada de resíduos sólidos - encontra suas raízes na lógica capitalista. Como resultados, verificou-se que o potencial econômico a ser extraído a partir da reutilização se revela imensamente inferior ao esperado, mormente pela falta de investimento no método de reciclagem, bem como pela desvalorização dos catadores de material reciclável, de modo que a adoção de uma perspectiva de manejo sustentável com inclusão social seria um possível caminho a ser trilhado. Nesse contexto, o intuito é contribuir para a reflexão sobre o impacto da gestão adequada dos resíduos sólidos no ambiente, tudo em consonância com um dos temas centrais da “Rio+20”, que é a busca do desenvolvimento sustentável com erradicação da pobreza

Collective values in an entrepreneurial world: imagining craft labour in cultural work
Authors: Jennifer Hambleton
Published: July 2018

Established entertainment industry unions are often perceived to be in decline in a new landscape of work that requires new forms of organising, but the International Alliance of Theatrical Stage Employees and Allied Crafts (IATSE), a union that represents precarious workers in the entertainment industries in North America continues to expand its membership. This article analyses a shift from seniority-based to skill-based hiring practices in IATSE locals that began in the mid-1990s. Case study research on the formation of a skill-based Canadian IATSE local in 1998 finds that skill-based and seniority-based hiring are each representative of different conceptions of labour. However, the picture this case study sketches also suggests that these seemingly opposing concepts of labour – skill-based and seniority-based – are entangled. The idea of hiring based on ‘skill’ proved to be an effective organising strategy, but intensified precarious working conditions for IATSE employees, and relied on a more entrepreneurial conception of labour.
Does Postpartum Contraceptive Use Vary By Birth Intendedness?
Authors: Guzzo Karen Benjamin , Eickmeyer Kasey , Hayford Sarah R.
Published: July 2018

CONTEXT

Women with an unintended birth have an elevated risk of subsequent unintended pregnancy, and multiple unintended pregnancies could exacerbate any negative consequences of such births. It is therefore important to understand whether postpartum contraceptive use differs by birth intendedness.

METHODS

Data on 2,769 births reported in the 2011–2015 cycles of the National Survey of Family Growth were used to examine postpartum contraceptive use. Life‐table estimates were employed to assess differences by birth intendedness in timing of postpartum contraceptive use, and multinomial logistic event history methods were used to model initial contraceptive uptake and efficacy by birth intendedness.

RESULTS

Compared with postpartum women whose births were on time or too late, those with seriously mistimed and those with unwanted births were more likely to first adopt a highly effective method (e.g., implant or IUD), rather than no method (relative risk ratios, 1.9 and 1.7, respectively); mothers with unwanted births were also more likely to first use least effective methods (e.g., condoms or withdrawal) instead of no method (1.5). Mothers with seriously mistimed births had a reduced likelihood of using either effective methods (e.g., the pill or injectable) or least effective methods, rather than highly effective ones (0.5 for each).

CONCLUSION

The elevated risk of repeat unintended fertility does not seem to be due to mothers’ initial postpartum contraceptive behavior. Whether mothers with unintended births use contraceptives less consistently, discontinue use sooner or switch methods more often than those with intended births remains to be seen.

Published: July 2018

Estimates of the genetic diversity of Large Japanese field mouse Apodemusspeciosus populations and identification of their plant food resources were conducted in an industrial green space, where were constructed on reclaimed land and belonged to the Aichi Refinery of Idemitsu Kosan Co., Ltd., in Aichi Prefecture, Japan. A total of six mitochondrial D-loop haplotypes were identified in 50 mice. Habitat condition with the highest number of captured individuals had abundant broad-leaved trees and understory vegetation. A minimum spanning network, which did not form a ring-shaped network, revealed that the hereditary population structure was weak. The low genetic diversity observed in the study area was thus attributed to isolation from other populations once the population in the study area by sea and road, which is more than 30 m wide. In order to identify which plant food resources were utilized by mice captured inside the industrial green space, partial chloroplast rbcL sequences were amplified by PCR from DNA extracted from 43 feces samples. Calculations of sample completeness curve revealed that 25 of the taxa identified in this study comprised approximately 90% of the food plant resources in the study area. Of the 21 plant families identified from the obtained rbcL sequences, members of the Rosaceae (28.0%), Fagaceae (17.2%), Lauraceae (14.2%) and Oleaceae (7.7%) were dominant. To ensure the continued survival of A. speciosuspopulation in this industrial green space would be to preferentially conserve plant species that are used as food resources by this species.
Lecturas y libros de texto: Las sociedades aborígenes en los textos escolares: de «indios salvajes» a «pueblos originarios». Una mirada en la larga duración.

Published: July 2018

En las últimas dos décadas una diversidad de temas y problemas vinculados a los pueblos originarios adquirió una presencia considerable en la agenda de políticas públicas y derechos.El sistema educativo argentino fue caja de resonancia de estos cambios y vehículo de expansión de nuevos relatos que tímidamente empezaron a poner interrogantes sobre el mito fundacional de una Argentina racial y culturalmente europea y blanca, y un territorio sin indios. Las disciplinas escolares vinculadas a las ciencias sociales fueron un terreno especialmente fértil para este proceso. En este artículo nos detendremos en el análisis del modo como fueron representadas las sociedades indígenas en los libros de texto para el nivel primario desde los albores del sistema educativo en las últimas décadas del siglo XIX hasta la actualidad. En particular nos centraremos en los capítulos dedicados a historia de los libros de texto para 4 grado, ya que es en ellos en los que aparece por primera vez ese contenido desde una perspectiva histórica, lo que le da cierto carácter fundante a las representaciones de los «indios» que los niños construyen en ese momento de la escolaridad.

Stem Cell Therapy for Demyelinating Disorders
Authors: Pazour Jan , Mokrý Jaroslav
Published: July 2018

Multiple sclerosis (MS) is a progressive disease of the central nervous system (CNS) that attacks mainly young people. It leads to the progressive deterioration of the neurological status. Histopatologically, this disease is characterized by appearance of multiple foci of the demyelination in white matter of the CNS, with various grade of an axonal loss. The current treatment is targeted on moderating the inflammatory process and symptomatic therapy. In spite of all this therapy, the course of the disease often progresses. The tissue of the CNS in mammalians, including humans, is able to provide some degree of spontaneous remyelination. Unfortunatelly the extent of this process is not sufficient for the complete restoration. The support of remyelination by using the cell manipulations is the aim of many experimental studies. Theoretically, it is possible to achieve remyelination either by exogenous induction of remyelination from endogenous sources (precursor cells) or by the real transplantation of myelin-forming cells intrafocally, intracerebroventricularly or into the blood stream. In this work, we present the brief view on the recent state of this topic. We present the list of the cell types, useable for cell transplantations and the summary of the growth factors influencing the behaviour of the oligodendroglial precursors. We are considering the hampers in usage of the cell therapy of demyelinating disorders in clinics.

Authors: Somanathan Rakesh V. , Šimůnek Antonín
Published: July 2018

Sinus lift operations have become a prerequisite for implantologists in the rehabilitation of atrophic posterior maxilla. Alloplasts and xenografts are the recent innovation in the world of grafting materials and have evolved in such a way as to compensate the need for autografts to be used in conjunction. In order to perfect the grafting materials, histomorphometry is the most often tool used to study the success of the augmentation. This article has tried to commemorate the importance of histomorphometry in maxillary antroplasty and also the success rate of β-tricalciumphosphate and deproteinized bovine bone as an augmentation material in maxillary augmentation.
The Effects of Pesticide Exposure on Serum Total Sialic Acid Levels
Authors: Kurtul Naciye , Arikan Burcu Canter
Published: July 2018

Pesticides used to increase agricultural production have hazard effects for human being health. The present study reports the serum levels of total sialic acid (TSA) in the pesticide applicators in the agriculture areas of the Kahramanmaras, Turkiye. This study included a total of 79 volunteer individuals. Pesticide group included 47 men who were working as pesticide applicators. Control group comprised healthy males (n=32), nonsmokers and nondrinkers and also nonexposured to pesticide and other chemicals chronically. Serum TSA level was measured with the Warren method modified by Pönniö et al. The TSA concentrations were significantly higher in the pesticide groups (p<0.001) than those of control subjects. We can conclude from the results obtained that serum TSA was affected by pesticide exposure. This finding may be an indication of harmful effects of pesticides. Increased serum TSA levels in pesticide exposure might be related to various diseases e.g. various cancers, which are also often associated with elevated serum TSA levels. However further studies are necessary to evaluate the concentrations of serum TSA in pesticide exposure.

In the whole group, we observed 0.68% occurence and in the subgroup of donors over 40 years of age even 1.18% occurrence of the serum paraprotein. We have presented our recommendations for the screening of monoclonal gammopathies in blood donors.
Cytoskeletal Changes in Non-Apoptotic Cell Death
Authors: Rudolf Emil , Červinka Miroslav
Published: July 2018

Dynamic morphology and cytoskeletal changes in Hep-2 cells exhibiting features of non-apoptotic cell death after treatment with zinc were studied using immunofluorescence microscopy and spectrofluorimetry. Among early morphological changes in treated cells was development of vacuolization, surface blebbing, relatively rapid cell detachment from substratum, cell shrinkage and, in some cases, appearance of membrane protrusions. Staining of microfilaments revealed rapid rearrangement and subsequent loss of F-actin accompanied by changes in the amount and localization of G-actin. The use of specific kinase and caspase inhibitors did not prevent surface blebbing as well as other morphological features in dying cells. Dying cells were only weakly positive for phosphatidyl serine and showed only a transient activation of caspase-9 with no signs of activation of caspase-3. These results suggest the existence of nonapoptotic cell death showing morphological features of both apoptosis and necrosis but, biochemically, resembling some other type of cell death.
Amylases and related glycoside hydrolases with transglycosylation activity used for the production of isomaltooligosaccharides
Authors: Casa-Villegas Mary , Marín-Navarro Julia , Polaina Julio
Published: July 2018

Isomaltooligosaccharides (IMOS) are sugars with health promoting properties that make them relevant for the pharmaceutical and food industries. IMOS have ample chemical diversity achieved by different α-glucosidic linkages and polymerization degrees, forming linear, branched and cyclic structures. Enzymatic synthesis of these compounds can be carried out by glycoside hydrolases (GHs) with transglycosylating activity. Different substrates are used for the synthesis: combinations of disaccharides and monosaccharides, or polymeric carbohydrates such as starch or dextran, which are converted to IMOS by a combination of hydrolysis and transglucosylation. In this review, the structural features of different enzyme families (GH31, GH13, GH70, GH57 and GH66) involved in IMOS synthesis are analysed. Focus is placed on structural traits that affect substrate and product specificity, and on the relative efficiency of transglucosylation and hydrolysis. Information resulting from site-directed mutagenesis and sequence alignments complements structural data to understand the role of specific residues in the performance of the enzymes. Altogether, these studies provide a frame of knowledge which may be used to design new enzymes with improved properties

Authors: Eigel Martin , Neumann Johannes , Schneider Reinhold , Wolf Sebastian
Published: July 2018

This paper examines a completely non-intrusive, sample-based method for the computation of functional low-rank solutions of high-dimensional parametric random PDEs, which have become an area of intensive research in Uncertainty Quantification (UQ).
In order to obtain a generalized polynomial chaos representation of the approximate stochastic solution, a novel black-box rank-adapted tensor reconstruction procedure is proposed.
The performance of the described approach is illustrated with several numerical examples and compared to (Quasi-)Monte Carlo sampling.

The paper also analyzes the most common mistakes of students and suggests ways to uncover them through tests. Based on these, it creates tests, compares the performance of the emulator and real device tests, and the proposed tools are partially retrospectively tested on assignments from the previous run of a particular Android application programming course. From partial results the paper suggests changes for the course in relation to the testing environment and deploys it in the background of the course alongside the manual evaluation. It describes testing experience, analyzes the results and suggests changes for the future
p21Waf1 deficiency does not decrease DNA repair in E1A+cHa-Ras transformed cells by HDI sodium butyrate
Authors: Igotti Maria , Gnedina Olga , Morshneva Alisa , Svetlikova Svetlana , Pospelov Valery
Published: July 2018

This study aimed to explore a role of p21Waf1 in γH2AX foci formation and DNA repair as assessed by a Host-Cell Reactivation Assay in wild-type (p21Waf+/+) and p21Waf1-deficient E1A+Ras-transformed cells. p21Waf1+/+ cells have low γH2AX background compared to p21Waf1−/− cells. The treatment with histone deacetylase inhibitor (HDI) sodium butyrate (NaBut) causes to accumulation of γH2AX in p21Waf+/+ cells with little effect in p21Waf−/− cells. Moreover, NaBut inhibits DNA repair in wt cells but not in p21Waf1−/− cells. This could be explained by the weakening of GADD45 and PCNA proteins binding in NaBut-treated p21Waf1-expressing cells but not in p21Waf1−/− cells. We suggest that in wt-ERas cells NaBut activates both p21Waf1 expression and a release of p21Waf1 from the complexes with E1A that leads to suppression of DNA repair and promotes γH2AX persistency. The absence of p21Waf1 is by itself considered by the cell as stressful factor with formation of γH2AX. But the lack of p21Waf1 interferes with an inhibitory effect of NaBut to inhibit DNA repair and thereby to stop concomitant accumulation of harmful mutations. We conclude that p21Waf1 is directly involved in control of genome integrity and DNA repair acting through modulation of the components of the DNA repair machinery.
Markov-Chain Monte-Carlo methods and non-identifiabilities
Authors: Müller Christian , Weysser Fabian , Mrziglod Thomas , Schuppert Andreas
Published: July 2018

We consider the problem of sampling from high-dimensional likelihood functions with large amounts of non-identifiabilities via Markov-Chain Monte-Carlo algorithms. Non-identifiabilities are problematic for commonly used proposal densities, leading to a low effective sample size.
To address this problem, we introduce a regularization method using an artificial prior, which restricts non-identifiable parts of the likelihood function. This enables us to sample the posterior using common MCMC methods more efficiently. We demonstrate this with three MCMC methods on a likelihood based on a complex, high-dimensional blood coagulation model and a single series of measurements.
By using the approximation of the artificial prior for the non-identifiable directions, we obtain a sample quality criterion. Unlike other sample quality criteria, it is valid even for short chain lengths.
We use the criterion to compare the following three MCMC variants:
The Random Walk Metropolis Hastings, the Adaptive Metropolis Hastings and the Metropolis adjusted Langevin algorithm.
