The aim of this study was to gather information on the indoor air quality of the Herbarium of Vascular Plants of the Museo de Ciencias Naturales de La PlataArgentinain relation to fungal propagules and inert particles.

This study was made using a volumetric system and two complementary sampling methods: 1 a non-viable method for direct evaluation, and 2 a viable method by culture for viable fungal propagules. The non-viable method led to ten spore morphotypes being found from related fungal sources.

A total of The viable method led to the finding of nine fungal taxa as viable spores that mostly belonged to anamorphic forms of Ascomycota, although the pigmented yeast Rhodotorula F. Harrison Basidiomycota was also found. Both the non-viable and viable sampling methods were necessary to monitor the bio-aerosol load in the La Plata Herbarium. Publicado por Elsevier España, S.

Concentrations of 21 Pb and Cs in sediment samples collected from two cores at a drainage channel to the La Plata river estuary in Buenos Aires, Argentinawere measured using ultralow-background detection systems. The 21 Pb data were used to determine the rate of sediment accumulation of the sites.

These results were correlated with some heavy metal chromium and lead concentrations of the samples in an attempt to characterize the historical input of contaminants due to the industrial development, which has taken place in this area over the last century. The Cs measurements demonstrate that cesium dating is not adequate in regions of the southern hemisphere.

The hydrochemistry of minor elements and traces such as bromide, lithium, strontium, uranium and selenium, together with the chemical analysis of major ions, has been used in the study of salinization process.

This process occurs in a semi-confined aquifer that corresponds to a Pliocene—Pleistocene fluvial environment. The semi-confined aquifer is located in the littoral of the cities of Ensenada and Berisso, in the region of the middle Río de la Plata estuary, Argentina.

Groundwater salinization was chicas en foz do iguacu weather july in the semi-confined aquifer in the coastal plain area, with salt contents that increase from the loess plain towards the river. In the salinized area, Li, Sr and Se enrichments occur, and are used as tracers of the average time that a substance remains in solution in sea water in the aquifer.

The study of such minor ions together with the geological evolution of the area made it possible to recognize that the salt water in the semi-confined aquifer corresponds to chicas en foz do iguacu weather july palaeo-intrusion of sea water associated with the Pleistocene—Holocene ingressions caused by the climate changes occurring during the Quaternary.

Urban transformations in the district of La Plata since the nineties. A compact or a diffuse city model? Full Text Available In the last decade several studies done on the transformation of the city from compact to more scattered and fragmented have shown the concern for the effects the open and scattered city may have upon the environment.

Although we consider that the urban models, "compact" and "diffuse", actually cannot be found in isolation, they are used to represent the extremes that relate the model of our city with these two models.

Determination of risk indices in quarries of two basins in La Plata Municipality Argentina.

Soil extraction is one of the main causes of degradation of this resource in Buenos Aires province. In La Plata municipality, soil is extracted at different depths for a variety of uses. Deep soil extraction creates quarries which have a negative impact on the environment, the landscape, the real estate value and life quality.

The inundated quarries become precarious swimming places where many people have drowned. When the quarries are used as garbage dumps, they can concentrate disease vectors or pollute groundwater through their leachates. The chicas en foz do iguacu weather july are often near vertical and can be susceptible to collapse. The methodology to calculate the risk index is based on the hypothesis that risk variables can be identified, individually assessed and combined in such a way that they would provide a numerical value reflecting the likelihood of accidents or diseases occurring as a consequence of quarry's presence.

The general objective of the project is to obtain an index for the quarries of the studied basins aimed at warning local authorities and affected persons about the sites where protection and reclamation measures are more urgently needed.

The values obtained are represented on a map showing the risk class of each quarry. It is concluded that the methodology is useful to determine priorities and can prove a good management tool for those involved in this problem [es.

Oil spill in the Rio de la Plata estuary, Argentina : 2-hydrocarbon disappearance rates in sediments and soils. The 6-month assessment of the oil spill impact in the Rio de la Plata described in the preceding paper [Colombo, J. Oil spill in the Rio de la Plata estuary, Argentina : 1 - biogeochemical assessment of waters, sediments, soils and biota. Environmental Pollution] was followed by a and month campaigns to evaluate the progress of hydrocarbon decay.

Individual aliphatic rate constants decrease with increasing molecular weight from 0. Aromatics disappearance rates were more homogeneous with higher values for methylated relative to unsubstituted species 0.

Continued hydrocarbon inputs, either from biogenic algal n-C15,17; vascular plant n-C27,29 or combustion related sources fluoranthene and pyreneappear to contribute to reduced disappearance rate.

Comparing the abundance and composition of litter in urban areas with different intensity of nightlife use in Mar del PlataArgentina.

Nightlife activities represents an important source of urban litter; the latter often being left behind or abandoned in public places and streets. Mar del Plata is a very important city on the Atlantic coast of Argentina and is the main tourism destination in the South Atlantic region of South America. However, chicas en foz do iguacu weather july studies on urban litter related to nightlife activities have been conducted in the area.

Here we assessed i the abundance and composition of litter, and ii the spatial and temporal variations of its abundance, diversity, richness and evenness in urbanized areas with different intensity of nightlife activities from April to March An overall of 13, items were counted. We found significant spatial differences in the abundance of litter between sampling sites, with the greatest amounts of litter chicas en foz do iguacu weather july the Alem site followed by the Hipólito site both with an intensive nightlife activity compared with the Chauvin site a quiet chicas en foz do iguacu weather july neighborhood.

The composition of litter of the Alem and the Hipólito sites was relatively similar and both sites differ with respect to the Chauvin site. Cigarette butts, papers, and plastics were the items that contributed most to the dissimilarity between sampling sites.

The diversity of litter was the single community parameter that significantly differed from the other seasons. We discussed the potential effect of nightlife activities on the amounts and quality of urban litter in the city of Mar del Plata.

Geology of the Río de la Plata and the surrounding areas of Argentina and Uruguay related to the evolution of the Atlantic margin. An integrated study of geological and geophysical data of the Río de la Plata region and its relation to the evolution of the Atlantic passive margin is herein described. This characterization is based on the available geological and geophysical information and on the correlation of the southern end of the best-known Santa Lucía Basin in Uruguay to the Salado Basin in Argentinaand their connection through the Quilmes Trough.

Furthermore, a new Meso-Cenozoic depocenter is characterized and identified as Recalada Trough, subparallely aligned to the Quilmes Trough and separated from it by the Magdalena-Montevideo High. This suggests an evolution from a triple junction where interconnected extensional arms developed, which have had common Mesozoic tectosedimentary histories related to the early opening of the Atlantic Ocean.

Based on the geophysical and geological evidence, the previously accepted existence in the Río de la Plata of a first-order structural feature along the international border between Argentina and Uruguay, associated to an ENE-WSW trending tectonic high, identified as Martín Chicas en foz do iguacu weather july, is unjustified.

The tectonic evolution of the Atlantic margin chicas en foz do iguacu weather july front of the Río de la Plata estuary is the consequence of a long deformation history starting in the Precambrian up to recent times. Each Precambrian, Paleozoic, Mesozoic and Cenozoic tectonic scenario adds different weak trends on the continental crust, which control the evolution of the sedimentary depocenters.

The presence of these tectosedimentary records influence the bathymetric control of the Río de la Plata and the dynamics of the recent estuarine deposits. The Meso-Cenozoic sedimentary infill is estimated to comprise considerable ranges of sandstones and conglomerates associated with faulted blocks of the crystalline basement, with expected petrophysical conditions oscillating in.

Sewage impact on the composition and distribution of Polychaeta associated to intertidal mussel beds of the Mar del Plata rocky shore, Argentina.

Full Text Available The polychaete composition and distribution within mussel beds were studied in order to assess organic pollution due to domestic sewage in a rocky shore of Mar del Plata Argentina during Four stations and a control site were randomly sampled around the local effluent. Quantitative data on polychaetes, as well as sediment accumulated among mussels and its organic carbon content were measured.

Polychaete distribution patterns are related to the organic matter gradient, being Capitella cf. At medial distances, the cirratulids Caulleriella alata Southern, and Cirratulus cirratus Müller, are very important in abundance. The syllids Syllis prolixa Ehlers, and S. The orbiniid Protoariciella uncinata Hartmann-Schröder, is subdominant at the control station.

Environmental modulation of the plankton community composition and size-structure along the eutrophic intertidal coast of the Río de la Plata estuary, Argentina.

Full Text Available In this study we investigated the spatial distribution of the plankton community, bacterio- phyto- and zooplankton, in relation with environmental conditions along the intertidal coast of the Río de la Plata estuary, Argentina. Plankton was analyzed in terms of species composition, abundance, biomass carbon content and size-structure. We aim to evaluate the potential effects of anthropogenic impacts e. We asked whether the natural structuring of the plankton by salinity and turbidity, known to be true of estuaries, is modified by eutrophication along the studied shoreline.

We found that the density and biomass of bacteria and phytoplankton were strikingly enhanced by high eutrophication levels along the intertidal southwest coast of the Río de la Plata estuary. We also found that the highest zooplankton density in the most polluted area but the biomass showed a different distribution pattern.

Nevertheless, when zooplankton was analyzed by means of its size fraction, we accordingly found that the microzooplankton biomass was positively associated with smaller-size phytoplankton groups and the most polluted study sites. Copepods were the major taxonomic groups that best represented the mesozooplankton biomass. We therefore expected that its distribution was modulated by the presence of its food items i.

In contrast, we found that the highest biomass of copepods occurred at the innermost site of the estuary and we found no significant association with other planktonic groups. Overall, this study highlights the noteworthy impacts of human activities modifying the functioning of this coastal ecosystem. The differences found in the taxonomic composition and size structure of the planktonic community assemblage between the most.

Full Text Available This study describes the macrofaunal assemblages of subtidal rocky reefs off Mar del Plata in order to compare the macro invertebrate assemblages settled on shipwrecks with those of nearby reef sand to characterize the fish fauna associated with natural NR and artificial AR reefs.

Topographic characterizations and surveys of invertebrates and fishes were performed in November and Decemberusing SCUBA diving. A non-parametric multivariate analysis was used to analyze the environmental and biological data.

The reefs were mainly distinguished by their depth and the position of the substrate. The red calcareous algae, Corallina officinalis, dominated the shallowest NR, whereas conspicuous mytilid assemblages of Mytilus platensis were present at depths over 3 m, sea anemones, Anthothoe chilensis, were more abundant between 6 and 10 m, and the soft coral, Tripalea clavaria, was found at nearly 20 m depth.

No differences were found between horizontal ARs and the adjacent NRs. The greatest differences were found between the communities of vertical and horizontal substrates, both in NRs and ARs. Fifteen fish species were recorded in the analyzed area.

Species having strong site fidelity, e. This pioneer study in the surveyed area showed that reef sallow the settlement of diverse benthic assemblages.

ARs also provide refuge for fishes. As sport fishing and diving are activities being carried out in Mar del Platawhere tourism is one of the main economic resources, the protection of such areas should be considered in conservation plans.

However, the most chicas en foz do iguacu weather july zircon population is Mesoproterozoic, showing maxima at 1. Zircons recovered from two sandstone levels in the Arroyo del Soldado Group Yerbal and Cerros San Francisco formations are mostly Archean in age, with maxima at 3. Palaeoproterozoic zircons are also prominent in this unit, with peaks at 2. Sandstones of the Villa Monica Formation show a unimodal zircon population of Transamazonian age peak at 2.

Sandstones of the Cerro Largo Formation are characterized by a dominant Transamazonian zircon population peaks at 2. The abundance of Mesoproterozoic detrital zircons is surprising. A proto-Andean, Mesoproterozoic belt is suggested as the source of the Mesoproterozoic detritus.

The sinistral reactivation of the Sarandi del Yi Shear Zone in the Cambrian, as a result of tangential collision of the Cuchilla Dionisio-Pelotas Terrane, may explain this observations.

Benthic communities on hard substrates covered by Limnoperna fortunei Dunker Bivalvia, Mytilidae at an estuarine beach Río de la PlataArgentina. Full Text Available The structure and composition of benthic communities on hard substrates covered by the nonindigenous bivalve Limnoperna fortunei Dunker, the golden mussel, were quantified in the middle zone of the Río de la Plata Estuary Argentina from April through March A total of 26 taxa were recorded.

The prevalence of L. The golden mussel alters both the structure and function of benthic native communities on hard substrates, allows a higher surface available for colonization and refuge, and provides food source to deposit-feeding organisms in the form of organic or residual material. The mussel also increases the abundance and diversity of taxa on hard substrata - such as Oligochaeta, Hirudinea, Tardigrada, Chironomidae, Copepoda, Tanaidacea, and Hydrachnidia.

Similarities and nonparametric multidimensional-scaling analyses indicated that the benthic composition had a seasonal variation. IQ Gains in Argentina between and The literature on IQ gains in Latin America is sparse. The gains are robust at the top of the curve as well as at the bottom.

Sewage-induced disturbance on polychaetes inhabiting intertidal mussel beds of Brachidontes rodriguezii off Mar del Plata SW Atlantic, Argentina. Full Text Available Continuous and short-term disturbances are produced on intertidal Brachidontes rodriguezii mussel beds by the sewage outfall of Mar del PlataChicas en foz do iguacu weather july Atlantic.

The effects on the associated polychaetes living on and between mussels were investigated, in both the spatial and short-term temporal scales. Multivariate methods show that the polychaete fauna was influenced by tidal level, total amount of sediment accumulated between mussels, distance from the sewage outfall, organic carbon of interstitial sediments, and sewage volume before and after the summer season. Environmental variables in the water column fitted with a spatial and temporal organic gradient.

Cirratulus sp. Syllis prolixa, S. Close to the outfall mussel density and dominance is low, and opportunist polychaetes successfully colonize organically enriched interstitial sediments. At intermediate distances from the outfall sediments retained by mussels reach their maximum values, and density of polychaetes is also high.

The control station is characterized by monolayered mussel beds and very low diversity of polychaetes. Opportunistic polychaetes increase in response to short-term increases of sewage discharge during the summer season November-March. Water samples were collected during 3 years — at three sampling sites in the Rio de la Plata estuary. Thirteen biological, physical, and chemical parameters were determined on the water samples.

The presence of microcystin-LR in the reservoir samples, and also in domestic water samples, was confirmed and quantified. Microcystin-LR concentration ranged between 0.

Principal components analysis was used to identify the factors promoting cyanobacteria growth. The observed fluctuating patterns of Microcystis aeruginosa, total coliforms, and Microcystin-LR were also described by probabilistic models based on the log-normal and extreme value distributions.

The sampling sites were compared in terms of the distribution parameters and the probability of observing high concentrations for Microcystis aeruginosa, total coliforms, and microcystin-LR concentration.

As I have mentioned in this column previously, research conducted by students is one means of accomplishing this goal. An Enzyme at Work is another useful resource. It can be used in any classroom where kinetics, catalysis, proteins, or enzymes are discussed. Because most high school students complete at least one year chicas en foz do iguacu weather july biology before enrolling in chemistry, developing the connections between biology and chemistry can be especially productive.

Connections between chemistry and biology often seem to be more real to students than do many of the phenomena we cite as applications. For example, students often are not able to make the connection between the excitation of electrons to produce electromagnetic radiation and anything that is personally relevant. The light given off by sodium or mercury vapor lights provides a common example of relating atomic emission to a useful process, but many students do not seem to find that particularly interesting.

The need to make a connection between biology and chemistry becomes especially meaningful to students when the chemical change occurs within the human body. As an example, the interaction of emitted electromagnetic radiation with human cells to cause well-tanned skin seems more relevant to a greater number chicas en foz do iguacu weather july students than the color of lights in a parking lot.

This issue contains an article that describes a useful application of light to kill cancer cells through use of photosensitizers p The process of photodynamic therapy PDT provides another example that could help students make a connection between the emission of electromagnetic radiation and the challenge of killing cancer cells without harming healthy cells.

Certainly this example is not a magic. The Nobel Prize in chemistry and the research that led to the awards are discussed in an article beginning on p An account of the winners appeared in last January's issue 5providing the basis for another convenient chicas en foz do iguacu weather july file. Water droplets on a surface of Magic Sand. For many students electrochemistry is among the least favorite of the topics included in first- or second-year high school chemistry - despite the many interesting applications that students encounter every day.

There are many reasons why students find the topic difficult, but misconceptions about current flow seem to present the largest obstacle to developing a conceptual understanding of electrochemical processes.

Two university faculty members and a high school teacher, Huddle, White, and Rogers, have developed a teaching model to help students confront and overcome their misconceptions pp They have conducted studies of the impact of the model's use on student learning in both high school and introductory college chemistry courses.

Particularly encouraging were the learning gains made by students with weak academic backgrounds. An action research project focused on student perspectives of small-group learning is described by Towns, Kreke, and Fields pp Although the project involved upper-division undergraduate university students, action research can be useful to any chemistry teacher who wishes to systematically examine and improve instructional methods and strategies.

This article may be especially interesting to readers who frequently employ small-group learning techniques in their classroom. Advances in the technology of multimedia delivery are having an impact on the format in which new JCE Software releases are available.

Alimentación de dos especies de anfibios Anura: Hylidae en la estación de bajas temperaturas y su relación con la acumulación de energía en Santa Fe, Argentina. Full Text Available Existe escasa información sobre la alimentación de las especies de anfibios activas durante la estación fría o las estrategias de utilización de reservas lipídicas como fuente de energía durante el periodo de bajas temperaturas.

Por lo tanto, se analizaron las estrategias de obtención y acumulación energética durante la estación de bajas temperaturas en un anfibio que se reproduce principalmente en otoño-invierno, Hypsiboas pulchellus Hp, y uno que lo hace en primavera-verano, Dendropsophus nanus Dn. Para ello se analizó la alimentación de ambas especies y se utilizó el peso de los cuerpos grasos CG como indicador del desarrollo de las reservas energéticas.

Si bien se encontró una elevada similitud en la dieta entre las especiesesto no implicó la ausencia de diferencias en las estrategias de obtención energética entre ellas. Por otro lado, el índice de vacuidad de Dn fue mayor al de Hp, mientras que sus CG se encontraron bien desarrollados, por lo que esta especie utilizaría en mayor medida sus reservas lipídicas como fuente de energía para transitar el período de bajas temperaturas y llegar en buenas condiciones a la temporada reproductiva en la próxima primavera-verano.

They are crucial in scanning tunnelling experiments and give important insight into the electron transport mechanism and charge distribution inside chains.

It is found that depending on the chain parity the local DOS at the Fermi level can form cone-like structures DOS cones along the chain. The general condition for the local DOS oscillations is obtained and the linear behaviour of the local density function is confirmed analytically. DOS cones are characterized by a linear decay towards the chain which is in contrast to the propagation properties of charge density waves, end states and Friedel oscillations in one-dimensional systems. We find that DOS cones can appear due to non-resonant electron transport, the spin-orbit scattering or for chains fabricated on chicas en foz do iguacu weather july substrate with localized electrons.

It is also shown that for imperfect chains e. We find that DOS cones can appear due to non-resonant electron transport, the spin—orbit scattering or for chains fabricated on a substrate with localized electrons.
