THE ROLE OF LOUROS AND ARACHTHOS RIVERS IN THE DEVELOPMENT OF SEDIMENTS OF THE ARTA'S PLAIN WITH THE CONTRIBUTION OF GEOCHEMICAL PARAMETERS
Authors: Βρυνιώτης Δ. , Παπαδοπούλου Κ.
Published: July 2018

The investigated region, which consists of a flat part to the north of Amvrakikos gulf, has high values with respect to Ni and Cr in alluvial soil. Specifically, within the area bounded by Rodia's lagoon, Arta's and Arachthos delta there are very high values of Ni and Cr with spatial correlation of the three higher classes of nickel (152-254 ppm) and chromium (111-186 ppm). In the surrounding area there are also elevated values of Ni and Cr. These high values of Ni and Cr are derived from the weathered ultra-basic materials, transported by Arachthos river from the northern part of the greater region, where the Pindos ophiolite complex is developed. Whereas, Louros river does not carry a load of ultra-basic materials. The conclusions of this investigation are: a) The most recent sediments of the flat part within Rodia's lagoon, Arta's and Arachthos delta are exclusive deposits of Arachthos river after its separation from Louros, b) In the surrounding area, and especially to the West there are older sediments deposited by Arachthos and Louros before their break-up, and c) The contribution of Louros in the sediments of the flat part is minor

Clinoptilolite is widely known for their uses especially in environmental applications. They have been utilized.in nuclear wastewater treatment and in land restoration. Irradiation emitted by nuclear liquid waste includes α, β and γ radiation. Irradiated clinoptilolite may exhibit crystal changes which affect the sorption of Cs+ and Sr2*. Sorption experiments with Cs+ and Sr2* were carried out separately. Solutions containing various concentrations of each element were brought in contact with untreated or irradiated (electron irradiation 1014 1015 e/cm2 and y-irradiation 70 Mrad) Armenian clinoptilolite. Additional experiments were carried out with solutions containing both Sr and Cs in varying proportions (75/25%, 50/50%, 25/75%) and concentrations (0.5 χ CEC and 2x CEC). The later types of experiments were contacted with untreated and irradiated Armenian clinoptilolite (yirradiation 70 Mrad, electron irradiation 1014 e/cm2). In solutions containing one ion (either Sr21 or Cs+), there is a slight increase of Cs+ uptake in the highest loadings of Cs (2x CEC, 1x CEC) for the γ-irradiated material. Electron Irradiation (1015 e/cm2) has not affected the sorption of Cs+. Clinoptilolite treated with y-irradiation exhibits decrease in Sr2* uptake and, equilibrium is attained at a significantly greater reaction time, especially when compared to Cs+. In binary solutions (Sr^-Cs*), clinoptilolite absorbs larger amounts of Cs+ compare to Sr2* and Cs+ uptake is instant compare to Sr2* where a delay is observed. There is a decrease in Sr2* sorption and an apparent delay in attaining equilibrium after y-irradiation. The same effects have been observed in the sorption of Sr2* after electron irradiation. Cs+ uptake has not been affected after clinoptilolite treatment with electron irradiation and y-irradiation.

Published: July 2018

Lime is a product with several uses. The most important are in metallurgy, in the manufacture of paper, glass, paints and sugar, for construction and environmental uses. At the present study the contribution of lime in the protection of environment is described. The lime industry product constitutes a significant segment of the environment industry with future prospects of growth. The treatment of municipal potable water, the treatment of urban sewages, the contribution in the neutralization of acid industrial discharges and the flue gas desulfurization, constitute the main environmental applications of the lime industry products. It is appreciated that the continuously increasing demand of products and technologies friendly to the environment over the next decade will have as a consequence the increase of lime production, particularly after the increasing application of stricter environmental legislation in national, as well as in global level.

There is no doubt that the world's need for oil and gas will continue to increase for the next two decates. In 2000 fossil fuels supplied 90% of global energy, with crude oil accounting 40% of the total, natural gas 25%, coal 25%,nuclear energy 7% and hydro-electricity 3%.But fossil fuels are exhaustible resources. Energy experts believe that the future global oil supplies will meet demand until global oil production has peaked between 2005 and 2013 causing a serious energy shortage 4 to 5 years later this. Globa1 community has to be prepared to face the coming energy crisis. Perhaps, under a global scenario of rising prices, a new stable energy mix could be achieved with massive conservation, alternative fuels and energy efficiency improvements
MINERALOGY AND ORGANIC MATTER CONTENT OF BOTTOM ASH SAMPLES FROM AGIOS DIMITRIOS POWER PLANT, GREECE
Authors: Kantiranis N. , Georgakopoulos Α. , Fiiippidis A. , Drakoulis A.
Published: July 2018

Four bottom ash samples from the Power Units of the Agios Dimitrios Power Plant were studied by the method of PXRD to determine their semi-quantitative mineralogical composition. Their organic matter content was calculated by a wet chemical process. Also, the loss on ignition was measured. The samples are constituted mainly of calcite, quartz and feldspars, while micas, clays, gehlenite and portlandite were determined in a few samples in smaller quantities. The amorphous material varied between 10-43 wt. %, while organic matter varied between 5-42 wt. %. Measurements of the loss on ignition overestimate the unburned lignite contents in the bottom ash samples. The management of bottom ashes with high contents of unburned lignite should differ to that of the fly ashes. The oxidation of the inorganic compounds of the unburned lignite may lead to environmental degradation of the landfill areas. Samples showing lower values of organic matter are suitable for a series of uses, such as: snow and ice control, as an aggregate in lightweight concrete masonry units,as a raw feed material for portland cement, as an aggregate in cold mix emulsified asphalt mixes, base or sub-base courses, or in shoulder construction. Systematic study of the unburned lignite of bottom ashes is needed for possible re-combustion.

Published: July 2018

With the present study it is intended to assess the depositional palaeoenvironment of the lower part of the Lignite-bearing Sequence in the Ptolemais Basin, and more specifically in the areas of Notio-Field and Tomeas-6 open pits. The sediments under study represent the seam between the Volcanic Tephra Layer and the Basal Marl, which constitute the roof and the floor, respectively. Coal-petrographic results showed that Huminite is the main macerai group (84-96%), while macérais from Liptinite and Inertinite groups display low values (<10%). In bulk lignite samples the main mineral phases are quartz, calcite, clay minerals and feldspars, while in the ashes the main phases are quartz, anhydrite and lime. The palaeoenvironment of the lignite formation was reconstructed using the lithological, coalpetrographic and mineralogical data, as well as coal-facies diagrammes. In Notio-Field Mine, at the early stages of lignite formation the conditions used to be limnotelmatic, while in Tomeas-6 Mine they were telmatic. Upwards the conditions turned to more telmatic in both mine areas. The vegetation was mainly herbaceous with some arboreal elements occurring mostly in Tomeas-6 area. The water influx was generally intense resulting in enhanced inorganic input

STUDY OF THE WALL ROCK ALTERATION OCCURRING IN ULTRAM A F I C ROCKS HOSTING MAGNESITE DEPOSITS, EVIA, GREECE,
Authors: Σερέλης Κ. , Γκάρτζος Ε. , Τσαουσίδου Π.
Published: July 2018

Three different kinds of alteration processes occur in the studied ultramafic host rocks of the magnesite deposits of N. Evia. In chronological order: Pre-magnesite event (serpentinization), syngenetic brown alteration and weathering. This paper concerns the syngenetic wall rock alteration of the ultramafic host rocks. Two types of wall rock alteration were distinguished. The first one named type (B-i) concerns cases of brown alteration accompanying thin to medium size veins of magnesite. Alteration is restricted in thin (a few cm to 20 cm) vein-parallel bands occurring on both sides of the vein. Alteration increases gradually towards the edges of the vein. The altered band consists mainly of abundant dolomite and/or quartz. The second type (B2) concerns argillic alteration of large ultramafic masses in areas with intense magnesite mineralization and can be observed along the walls of the open pit mines. Secondary vermiculite has been formed in this case. Both types are related to the genesis of the magnesite deposits
MINERAL ASSEMBLAGES AND GENESIS OF THE Cu-Au EPITHERMAL DEPOSITS IN THE SOUTHERN PART OF THE PANAGUYRISHTE ORE DISTRICT, BULGARIA
Authors: Bogdanov K. , Tsonev D. , Popov K.
Published: July 2018

Epithermal Cu-Au deposits hosted within volcanic rocks (Radka, Elshitsa, Krassen) are related to Late Cretaceous andesite-dacite volcanic terrain in the Panagyurishte ore district. The Cu-Au ores are linked by a similar mineralogy and differ by the ratio of tennantite, bornite, enargite and discrete trace minerals of Ga, Ge, In and Bi (e.g., roquesite, germanite, betekhtinite, renierite, vinciennite, aikinite). Bi-Se-Te and Ga-Ge-ln-Sn signature with pronounced Au-enrichment of the bornite rich ores is a characteristic feature underlying the increasing role of the fS2/f02 control during the transition from IS te HS environment. Formation of the epithermal Cu-Au deposits appears to have occurred during a single broad event of contemporaneous formation of epithermal and porphyry systems.The close connection between the volcano-plutonic structures facilitates the multistage and polycyclic character of their hydrothermal systems, the similar character of the epithermal ores and the mineral succession in Elshitsa, Radka and Krassen deposits. The ô^S ratios in the sulphide minerals range from -6.7 to 4.0, suggesting comparable magmatic sources for the epithermal mineralizing fluids and close link with porphyry environment.
PRELIMINARY STUDY OF ALTERED TERTIARY VOLCANICLASTIC ROCKS IN THE AREA OF ASPROULA , ΝΕΑ SANTA, RODOPI PERFECTURE, THRACE, NE GREECE

Published: July 2018

The area of Asproula is part of the Tertiary volcanosedimentary basin of Komotini, West Thrace. The geological structure of the area comprises metamorphic rocks of the Rhodope zone and Tertiary volcano-sedimentary rocks. The Tertiary sequence consists of three units: a) the lower unit, in contact with metamorphic rocks comprises sandstones-siltstones b) a unit, which comprises andesitic tuffs and c) a highe: unit consisting of dacitic-rhyodacitic volcaniclastics alternated with tuffites, siltstones, sandstones and marls forming a sequence about 150m thick. The acid volcaniclastics have been altered to clay minerals (mixed layer l-S, kaolinite, ), analcime, albite, and mordenite. The andesitic tuffs are slightly altered to smectite. Moreover in the andesitic tuffs laumontite and scolecite have formed along faults . According to the distribution of characteristic alteration minerals a zonation of alteration has been distinguished. Hence, the lower part of dacitic- ryodacitic tuffs has been altered to analcime + mixed layer l-S + quartz or albite + l-S + quartz, whereas in the upper part the volcaniclastics have been altered to kaolinite or mordenite. In the upper part of the dacitic-rhyodacitic sequence mordenite occurs in distinct thin pyroclastic flows (<5m thickness). The mode of succession of the mordenitic-kaolinitic alteration in the upper parts of the volcaniclastic sequence suggests rapid change in the chemistry of the mineral forming fluids. It is possible that temperature controlled the formation of mordenite. The presence of R1 ordered mixed layer l-S throughout the stratigraphie sequence suggests that the temperature during alteration exceeded 90° C. Moreover, the appearance of neo-formed albite in the lower part of the succession suggests that the temperature during alteration exceeded 120° C, in the lower parts of the formation.
PROVENANCE OF PINDOS FLYSCH DEPOSITS IN METSOVO AND FOURNA AREAS USING SCANNING ELECTRON MICROSCOPY AND MICROANALYSIS

Published: July 2018

Pétrographie observation of sandstones that contain detrital grains and lithic fragments along with microanalytical data from certain minerals suggest that detrital material in Pindos flysch deposits, in Metsovo and Fourna areas, may have been sourced in the Pindos ophiolite and the Pelagonian metamorphic rocks; additionally some material from Fournas has probably been derived from the Koziakas ophiolite outcrop. The Loumnitsa Unit (Pindos ophiolite), has probably supplied the Pindos foreland with ma+erial from the erosion of amphibolites while the Dramala Unit was the most probable source of spinels and ultramafic material. Fragments of acid plutonio rocks have been observed, too, owing their origin from the plutonite of Vamounta-Kastoria (Pelagonian Zone). The area of Fourna has been also fed by the Koziakas ophiolites, as evidenced from the composition of chlorites and epidotes.
GARNETS OF MICA-SCHISTS FROM CRNI VRH AND RESAVSKI HUMOVI (SERBIA)
Authors: Eric S. , Milovanovic D. , Babic D.
Published: July 2018

Metamorphic rocks of the Crni Vrh and Resavski Humovi area belong to the north-northwestern part of the Serbo-Macedonian Composite Terrane and consist of different types of mica-schists, gneisses and amphibolites. Mica-schists are composed of biotite, muscovite, garnet, staurolite, kyanite, small quantity of Kfeldspar, acid plagioclase and quartz. Accessory minerals are apatite, zircon, tourmaline and ilmenite. Garnets in mica-schists from both localities occur as subhedral to anhedral porphyroblasts from 0.2 to 10mm in size. Most garnets are oriented parallel to the dominant foliation. Garnets from the Crni Vrh mica-schists contain more spesartine component than garnets from Resavski Humovi, while almandine component show opposite tendency. The difference between those garnets is clearly visible, as well as zonality expressed through the increase of almandine component from center to the grain rim. The spesartine component as mentioned above, shows the opposite tendency. Using different geothermometers and geobarometers it was found that mica-schists from Crni Vrh were formed at temperatures from 550-600°C and pressures from 6-6.2 kbar, while micaschists from Resavski Humovi developed at slightly lower temperatures (520-560°C) and at some higher pressures (7-7.3 kbar).

Published: July 2018

A number of polished thin sections from two cross sections within the Pindos foreland deposits were petrographically examined while microanalyses on certain minerals were carried out. Chemistry of these minerals is compared to analogous phases occurring in several formations in the neighbourhood of the studied areas which can stand as source areas. Our results reveal that the most probable source materials include the Pindos, Koziakas (and probably and Vourinos) ophiolite complexes, as well as metamorphic sequences of the Pelagonian Zone
MINERALOGY AND PETROLOGY OF THE BRNJICA GRANITOIDS (EASTERN SERBIA)
Authors: Vaskovic N. , Kuroneos A. , Christofides G. , Sreckovic-Batocanin D. , Milovanovic D.
Published: July 2018

The Variscan Brnjica granitoids in East Serbia, occurring in the Kucaj Terrane of the Carpatho-Balkanides, are composed of hornblende - biotite tonalité (TON), biotite granodiorite (GRD), twomica granite (TMG) and leucogranite (LG). The rocks analyzed are slightly peraluminous. A preplate collision tectonic environment is supported based on the R1-R2 discrimination diagram. A two-step mixing plus fractional crystallization (MFC) process is considered responsible for the evolution of the Brnjica granitoids. In the 1st step, the parental magma (having the composition of the more basic TON) is forming the mineral assemblage Pl596Biio.3Hbio.7Mto.7Titi.oQzi7.7 by 44% crystallization, and at the same time is mixed (r=0.1) with a magma similar to TMG to give a melt similar to the composition of the less evolved GRD. In the 2nd step, 60% crystallization (Pl39oKfi oBÌ25oZr06Api aMti 4Titi 0QZ303) of the less evolved GRD and a simultaneous mixing with the same acid magma (TMG) but with higher r (0.6) is needed for the genesis of GRD group. The TON could originate in the crust by melting of amphibolites and basalts under various P-T conditions while the granites could be crustal melts produced by melting of amphibolites, gneisses, graywackes and pelites. Pressure of 2.3 to 4.1 kb and temperatures from 626 to 813 °C were calculated for TON, using hornblende and co-existing hornblende and plagioclase compositions respectively.

The contribution of Geochemistry in the assessment of environmental conditions in soils and aquatic systems and in the application of remediation methodologies
Authors: ΒΑΡΝΑΒΑΣ Σ. Π.
Published: July 2018

A main present day geochemical application is the assessment of the environmental conditions prevailing in a variety of natural and anthropogenic environments and the application of remediation methodologies. For this aim geochemical studies lead to the determination of the concentration levels and the source of pollutants. In addition through biogeochemical studies the behavior of pollutants in various environments is determined (i.e. rate of enrichment or dilution in space and time, dispersion processes etc.). On the basis of the results of geochemical studies remediation methodologies and methodologies leading to prevention of toxic elements in getting into the food chain are applied while criteria are put for the quality of soils, water etc. In addition decision makers are helped to make the necessary and right decisions in the management of toxic waste.

Published: July 2018

The article presents the methodology and preliminary results from analytical simulations regarding fault rupture propagation through soft soil cover. The analyses employ the Finite Difference method for the numerical solution of boundary value problems, combined with appropriately chosen constitutive model for the shearing response of the soil cover, velocity time history for the rupture and boundary conditions. Analytical predictions are compared to field observations for an overall, qualitative as well as quantitative, evaluation of the methodology. In addition, results from an extensive parametric study are used for an initial definition of the basic design parameters in the vicinity of the fault trace and their possible range of variation.

Published: July 2018

Background: Foot and mouth disease virus (FMDV), a member of the picornaviridae that causes vesicular disease in ungulates, has seven serotypes and a large number of strains, making universal detection challenging. The mature virion is made up of 4 structural proteins, virus protein (VP) 1 – VP4, VP1-VP3 of which form the outer surface of the particle and VP4 largely contained within. Prior to mature virion formation VP2 and VP4 occur together as VP0, a structural component of the pre-capsid which, as a result of containing the internal VP4 sequence, is relatively conserved among all strains and serotypes. Detection of VP0 might therefore represent a universal virus marker.

Methods: FMDV virus protein 0 (VP0) was expressed in bacteria as a SUMO fusion protein and the SUMO carrier removed by site specific proteolysis. Rabbit polyvalent sera were generated to the isolated VP0 protein and their reactivity characterised by a number of immunoassays and by epitope mapping on peptide arrays.

Results: The specific VP0 serum recognised a variety of FMDV serotypes, as virus and as virus-like-particles, by a variety of assay formats. Epitope mapping showed the predominant epitopes to occur within the unstructured but highly conserved region of the sequence shared among many serotypes. When immunogold stained VLPs were assessed by TEM analysis they revealed exposure of epitopes on the surface of some particles, consistent with particle breathing hitherto reported for some other picornaviruses but not for FMDV.

Conclusion: A polyvalent serum based on the VP0 protein of FMDV represents a broadly reactive reagent capable of detection of many if not all FMDV isolates. The suggestion of particle breathing obtained with this serum suggests a reconsideration of the FMDV entry mechanism.

Published: July 2018

Background: Endemic and seasonally recurring respiratory viruses are a major cause of disease and death globally. The burden is particularly severe in developing countries. Improved understanding of the source of infection, pathways of spread and persistence in communities would be of benefit in devising intervention strategies.

Methods: We report epidemiological data obtained through surveillance of respiratory viruses at nine outpatient health facilities within the Kilifi Health and Demographic Surveillance System, Kilifi County, coastal Kenya, between January and December 2016. Nasopharyngeal swabs were collected from individuals of all ages presenting with acute respiratory infection (ARI) symptoms (up to 15 swabs per week per facility) and screened for 15 respiratory viruses using real-time PCR. Paediatric inpatient surveillance at Kilifi County Hospital for respiratory viruses provided comparative data.

Results: Over the year, 5,647 participants were sampled, of which 3,029 (53.7%) were aged <5 years. At least one target respiratory virus was detected in 2,380 (42.2%) of the samples; the most common being rhinovirus 18.6% (1,050), influenza virus 6.9% (390), coronavirus 6.8% (387), parainfluenza virus 6.6% (371), respiratory syncytial virus (RSV) 3.9% (219) and adenovirus 2.7% (155). Virus detections were higher among <5-year-olds compared to older children and adults (50.3% vs 32.7%, respectively; χ2(1) =177.3, P=0.0001). Frequency of viruses did not differ significantly by facility (χ2(8) =13.38, P=0.072). However, prevalence was significantly higher among inpatients than outpatients in <5-year-olds for RSV (22.1% vs 6.0%; χ2(1) = 159.4, P=0.0001), and adenovirus (12.4% vs 4.4%, χ2(1) =56.6, P=0.0001).

Conclusions: Respiratory virus infections are common amongst ARI outpatients in this coastal Kenya setting, particularly in young children. Rhinovirus predominance warrants further studies on the health and socio-economic implications. RSV and adenovirus were more commonly associated with severe disease. Further analysis will explore epidemiological transmission patterns with the addition of virus sequence data.
As lógicas por trás das políticas de regularização fundiária: a alteração de paradigma pela Lei 13.465/2017
Authors: Ferreira filho Paulo sergio
Published: July 2018

As políticas de regularização fundiária devem ser cuidadosamente planejadas e executadas, refletindo as normas sociais nas comunidades beneficiárias, bem como, aliada à titulação da propriedade, implementar uma rede de serviços públicos e infraestrutura urbana. Tal conclusão é atingida após a análise econômica dos impactos dos referidos programas, apontando como a Lei 13.465/2017 operou uma mudança de lógica no marco legal da regularização fundiária, centrando-se numa lógica de mercado. Contudo, aponta-se que uma mera lógica de concessão de títulos de propriedade individualizada pode amentar a vulnerabilidade dos beneficiários, causando uma maior insegurança da posse dos imóveis por eles exercida, o que seria sinal do fracasso de uma política pública que deve estar voltada para a efetivação do direito social à moradia e a diminuição da pobreza. Daí a necessidade de cada projeto se atentar para os usos e costumes da comunidade afetada, a melhoria efetiva das condições urbanas e de habitabilidade, bem como a criação de mecanismos para que incentivem que as pessoas beneficiadas continuem na formalidade após a execução do programa.
Increasing access to children's palliative care education through e-learning: a review of the ICPCN experience
Authors: Daniels Alex , Downing Julia
Published: July 2018

Education is integral to the development of children's palliative care (CPC) globally; thus, the International Children's Palliative Care Network (ICPCN) developed a training programme including face-to-face and e-learning programmes to increase access to CPC. A review of ICPCN's e-learning programmes was undertaken in April/May 2018. At the time of writing, there are seven courses available, with more scheduled to be released in the near future. All courses are available in English, with some available in other languages, including Mandarin, Czech and Dutch. Between May 2016 and April 2018, 1501 individuals accessed the courses from 96 countries (39% nurses, 28% doctors). English was the prevalent language used (74%), followed by Spanish (8.5%). To date, over 3106 participants have accessed the e-learning programme from 124 countries. An evaluation in 2015/16 found that >80% of respondents said the courses were clear, understandable, rated them highly and found them useful. Some 75% of respondents reported improved knowledge, skills and change in attitude, while 61% reported a change in practice. The ICPCN e-learning platform is an innovative way of improving knowledge and understanding of CPC, thereby increasing the accessibility and availability of CPC.

Published: July 2018

Objective

Cement thickness of at least 2 mm is generally associated with more favorable results for the femoral component in cemented hip arthroplasty. However, French-designed stems have shown favorable outcomes even with thin cement mantle. The biomechanical behaviors of a French stem, Charnley-Marcel-Kerboull (CMK) and cement were researched in this study.

Methods

Six polished CMK stems were implanted into a composite femur, and one million times dynamic loading tests were performed. Stem subsidence and the compressive force at the bone-cement interface were measured. Tantalum ball (ball) migration in the cement was analyzed by micro CT

Results

The cement thickness of 95 % of the proximal and middle region was less than 2.5 mm. A small amount of stem subsidence was observed even with collar contact. The greatest compressive force was observed at the proximal medial region and significant positive correlation was observed between stem subsidence and compressive force. 9 of 11 balls in the medial region moved to the horizontal direction more than that of the perpendicular direction. The amount of ball movement distance in the perpendicular direction was 59 to 83% of the stem subsidence, which was thought to be slip in the cement of the stem. No cement defect and no cement breakage were seen.

Conclusion

Thin cement in CMK stems produced effective hoop stress without excessive stem and cement subsidence. Polished CMK stem may work like force-closed fixation in short-term experiment.

El debate sobre los mecanismos capaces de frenar la publicidad engañosa es amplio y profundo en el terreno de las éticas aplicadas y del derecho. Junto al ampliamente estudiado concepto de autorregulación aparece en la actualidad el término de corregulación que se presenta como capaz de trascender y mejorar al primero. Sin embargo, la corregulación no se interpreta de forma homogénea sino que adopta cierta polisemia en función de las propuestas. El objetivo de este artículo, cuya metodología es teórica y cualitativa, consiste en estudiar el significado, las novedades y las variantes de la corregulación. Como resultados se propone diferenciar entre una visión reguladora y otra participativa de la corregulación.

The study of urban arborization can generate great contributions to urban planning, mainly for new and fast-growing cities. Aiming quantifying and qualifying urban arborization in Cassilândia, Chapadão do Sul, Costa Rica and Paranaíba, in Mato Grosso do Sul State, Brazil, we performed a survey of tree species present in 30 blocks of each city. All trees were evaluated regarding tree size, planting site, pruning and physical conservation status. The species were classified native or exotic. There were 3180 individuals and 89 species, with the highest abundance of Brazilian native trees (69%), although the richness of exotic species was higher (78%). Chapadão do Sul had the largest individuals number and Paranaíba, the smallest. The diversity index was low for all cities, especially because of the large number of oitizeiros (Licania tomentosa) registered, totaling more than half of the trees surveyed. The widespread use of only one species, as found for the oitizeiro in this study, is not recommended because it reduces diversity and increases the chances of diseases and pests in trees in the urban environment. However, it was observed a high incidence of species used in urban arborization, and tree maintenance aspects, such as pruning, were satisfactory in the four studied cities.

Cassava is the fourth largest staple food after rice, wheat and maize. Cassava is produced in the tropical and sub-tropical countries. Currently, the global production of cassava is about 215,436,496 tons. Out of these, Nigeria accounts for 20.3%, being the largest producing nation. During processing of cassava flour (Gari), three main wastes are generated including cassava mill effluents (CME), solid and gaseous emission. This paper reviews the impacts of CME in Nigeria. The study found that CME’s physicochemical quality often exceeds the limit for effluents discharge onto land and surface water as recommended by Federal Environmental Protection Agency (FEPA), Nigeria. CME alters the quality of soil and water with regard to physicochemical, heavy metal and microbial characteristics. CME can induce toxicological effects on the environments and its biota including humans, fisheries, flora and fauna. The impacts are mostly associated with physicochemical (viz: odour, cyanide, acidic, dissolved oxygen, biological and chemical oxygen demand, conductivity) and heavy metals characteristics. Therefore, there is the need for treatment and sustainable management strategies of CME through biotechnological advancement.

Hengshui Lake Wetland is the only national wetland and bird nature reserve in the North China Plain. It plays an important role in maintaining the species diversity and ecological balance. In recent years, due to industrial and agricultural production, infrastructure and ecological environment construction and other reasons, the infiltration, runoff, evapotranspiration and other water balance elements was changed, which reduced runoff into the lake. In order to ease the tense water resources situation in the region, Hengshui Lake is replenished each year by Yellow River water. Although Diversion Yellow River Wetland has made direct water supply protection, but also affected the ecology and environment of Hengshui Lake wetlands. In order to understand how artificial water diversion can affect the ecological environment of natural lakes, this paper analyzes the effects of artificial water storage on the water quality of the lake by using the measured data of water samples in the lake. The results showed that the water level of Hengshui Lake showed an upward trend after the diversion from the Yellow River. Comprehensive pollution index showed a downward trend, but Hengshui Lake wetlands are still slightly polluted. Diversion of Yellow River diversion into the lake of the ecological health of Hengshui also caused some impact.
Lecturas y libros de texto: Memorias culposas. Las representaciones de la Guerra del Paraguay en manuales escolares de Uruguay y la Argentina de la última década.
Authors: Bel Rolando
Published: July 2018

La Guerra del Paraguay (1864–1870) fue uno de los eventos más trágicos y de los más determinantes en el proceso de conformación de los estados nacionales en la Cuenca del Plata.En la región se definieron nuevas tensiones limítrofes y se pusieron en juego los intereses de Argentina y Brasil, en gran medida como consecuencia de la derrota de la nación paraguaya.El mencionado conflicto ha sido una problemática muy poco abordada en los textos escolares de los países de la Triple Alianza, con la excepción de Paraguay. Nuestra indagación se focaliza en intentar explicar cómo la temática es abordada en los sistemas de enseñanza argentino y uruguayo. Para ello se analizan en forma comparada, manuales escolares de estos países, intentando establecer la mirada historiográfica de los autores, el espacio dedicado a la cuestión y en particular, las similitudes y diferencias entre estos corpus textuales.

Authors: Billán Yésica Alejandra
Published: July 2018

El objetivo de este artículo es explorar cómo opera relación entre las prácticas cotidianas de las escuelas en torno a la transmisión de la historia reciente y el contexto que lo circunda.Para tal fin, presenta el análisis del caso de una institución educativa de nivel secundario de la provincia de Buenos Aires, próxima a la guarnición militar de Campo de Mayo, y el protagonismo que adquieren los alumnos al convertirse en protagonistas y autores de un producto cultural destinado a la comunidad. En primer lugar retoma los aportes de la cultura escolar para situar la transmisión de la historia reciente. A continuación sitúa el contexto donde se encuentra inserta la institución y las miradas que los diferentes actores imprimen sobre el proyecto institucional «30 años de democracia». Finalmente esboza algunas reflexiones en torno a las prácticas escolares cotidianas y las invenciones que, a partir del compromiso institucional, docente, de alumnos y la comunidad, pueden generar nuevos productos culturales que vuelven a la comunidad.

Published: July 2018

Objectives: Activity of Serum Adenosine Deaminase (ADA), a main enzyme in purine degradation and considered as a marker for non-specific T cell activation, in psoriasis has been investigated in a few studies with conflicting results. Design and Methods: To evaluate the significance of serum ADA activity in psoriasis, and analyze whether ADA activity may be related to disease activity, we performed a prospective study with 38 cases of psoriasis and 24 healthy volunteers. Patients were divided into two groups as cases with local and stable lesions (Group i, n: 20) and severe cases with extensive involvement (Group ii, n: 18). Serum ADA activity was determined by modified Guisti procedure. Results: When taken into consideration of all patients -regardless of the severity of the disease- the mean serum ADA activity of psoriatics did not differ significantly from that of controls (p>0.05). However, it was higher in Group ii than in Group i and healthy controls (respectively p<0.001 and p<0.05). A significant decrease was observed also after therapy only in Group ii (p<0.001). Conclusion: Serum ADA activity may be correlated to the disease activity of severe psoriasis. We suggest that it might be a serologic marker for follow-up of in such cases. It could be used in predicting relapses before clinical findings as well as in deciding to stop or decrease systemic therapies at the right time, which have potential to cause severe systemic side effects when given for a long period. Further studies with larger case populations are required to support our findings.
Renal Tubular Impairment in Children with Idiopathic Hypercalciuria
Authors: Skálová Sylva , Kutílek Štěpán
Published: July 2018

Idiopathic hypercalciuria (IH) is defined as hypercalciuria that persists after correction of dietary inbalances and has no detectable cause. The excretion of urinary N-acetyl-beta-D-glucosaminidase (U-NAG), a marker of proximal tubular damage, has been previously reported as either increased or normal in children with IH. We evaluated U-NAG in 20 children (13 boys and 7 girls, mean age 10.3 years ± 5.7 SD) with IH (urinary calcium excretion above 0.1 mmol/kg/24 hours, with no detectable cause) and with otherwise normal renal function tests. Ultrasound examination revealed urolithiasis (n = 4) and nephrocalcinosis (n = 1). The U-NAG values were evaluated in the spot urine collected from the second morning void and calculated as the urinary NAG/creatinine ratio (U-NAG/Cr) and expressed in nkat/mmol. The 24-hour urinary calcium excretion (U-Ca/24h) was assessed in a urinary sample from 24-hour collected urine and calculated in mmol/kg. The obtained results of U-Ca/24h and U-NAG/Cr were expressed as Z-scores. When compared to the reference data, the U-Ca/24h and U-NAG/Cr were significantly higher (p=0.0004 and p=0.006, respectively). There was no correlation between the U-NAG/Cr and U-Ca/24h (r = 0.18, p = 0.20). The U-NAG/Cr values were significantly higher in the 5 patients with urolithiasis/nephrocalcinosis, whether compared to the rest of the group (p=0.02), or to the reference data (p=0.01). The U-NAG/Cr activity was higher in 15 children without urolithiasis/nephrocalcinosis when compared to reference data (p < 0.01). There was no difference in U-Ca/24h between the children with and without urolithiasis/nephrocalcinosis (p = 0.58). These findings suggest that tubular impairment, as reflected by U-NAG/Cr, might occur in children with IH, especially in patients with urolithiasis/nephrocalcinosis. There doesn’t seem to be a direct relationship between the U-NAG/Cr activity and the degree of calcium leakage.

Published: July 2018

During the course of an outbreak due to Verona integron-encoded Metallo-β-lactamase (VIM)-producing Klebsiella pneumonia (KP) in the neonatal intensive care unit (NICU) of Maggiore Hospital in Bologna (Italy), an 8-day-old extremely low birth weight (ELBW) infant developed a severe ventilator-associated pneumonia (VAP) with concomitant bacteraemia. Although the microorganism was susceptible only to colistin and tigecycline, the patient was successfully treated with a combination of antibiotics including high-dosage, prolonged infusion of meropenem (MEM) and intravenous plus aerosolised gentamicin (GEN). This report highlights that, even when the microorganism is considered non-susceptible to MEM and GEN, the combination of these two agents could have a significant survival benefit.
