Escaping a Neighborhood Along a Prescribed Sequence in Lie Groups and Banach Algebras
Authors: Badea Catalin , Devinck Vincent , Grivaux Sophie
Published: October 2019

It is shown that Jamison sequences, introduced in 2007 by Badea and Grivaux, arise naturally in the study of topological groups with no small subgroups, of Banach or normed algebra elements whose powers are close to identity along subsequences, and in characterizations of (self-adjoint) positive operators by the accretiveness of some of their powers. The common core of these results is a description of those sequences for which non-identity elements in Lie groups or normed algebras escape an arbitrary small neighborhood of the identity in a number of steps belonging to the given sequence. Several spectral characterizations of Jamison sequences are given, and other related results are proved.

On proximal fineness of topological groups in their right uniformity
Authors: Bouziad Ahmed
Published: October 2019

A uniform space X is said to be proximally fine if every proximally continuous function defined on X into an arbitrary uniform pace Y is uniformly continuous. We supply a proof that every topological group which is functionally generated by its precompact subsets is proximally fine with respect to its right uniformity. On the other hand, we show that there are various permutation groups G on the integers N that are not proximally fine with respect to the topology generated by the sets {g ∈ G : g(A) ⊂ B}, A, B ⊂ N.
Existence results of delay and fractional differential equations via fuzzy weakly contraction mapping principle
Authors: Tabassum Rehana , Azam Akbar , Mohammed Shehu Shagari
Published: October 2019

The purpose of this article is to extend the results derived through former articles with respect to the notion of weak contraction into intuitionistic fuzzy weak contraction in the context of (T,N,∝) -cut set of an intuitionistic fuzzy set. We intend to prove common fixed point theorem for a pair of intuitionistic fuzzy mappings satisfying weakly contractive condition in a complete metric space which generalizes many results existing in the literature. Moreover, concrete results on existence of the solution of a delay differential equation and a system of Riemann-Liouville Cauchy type problems have been derived. In addition, we also present illustrative examples to substantiate the usability of our main result.

Abstract. The aerosol optical characteristics in the urban area of Rome were retrieved over a period of 7 years from March to September 2010–2016. The impact of aerosol single scattering albedo (SSA), optical depth (AOD), estimated at 400 nm, and Ångström exponent on the ultraviolet (UV) index has been analyzed. Aerosol optical properties are provided by a PREDE-POM sun-sky radiometer of the ESR/SKYNET network and the UV index values were retrieved by a Brewer spectrophotometer both located in Rome. Chemical characterization of urban PM10 (particulate matter 10 micrometers or less in diameter) samples, collected during the URBan Sustainability Related to Observed and Monitored Aerosol (URBS ROMA) intensive filed campaign held in summer 2011 in the same site, was performed. PM macro-components were grouped in order to evaluate the contribution of the main macro-sources (SOIL, SEA, SECONDARY INORGANIC, ORGANICS and TRAFFIC) and the analysis of the modulation of their concentration was found to strongly affects the absorption capability of the atmosphere over Rome. The surface forcing efficiency, provided by the decreasing trend of UV index with AOD, which is the primary parameter affecting the surface irradiance, was found very significant, probably masking the dependence of UV index on SSA and Ångström exponents. Moreover it was found greater for larger particles and with a more pronounced slope at the smaller solar zenith angle. In Rome large particles are generally less absorbing since related to the presence of SOIL and SEA components in the atmosphere. The former contribution was found much higher in summer months because of the numerous episodes of Saharan dust transport.

Abstract. Evaporation (E) and transpiration (T) respond differently
to ongoing changes in climate, atmospheric composition, and land use. It is
difficult to partition ecosystem-scale evapotranspiration (ET) measurements
into E and T, which makes it difficult to validate satellite data and land
surface models. Here, we review current progress in partitioning E and T and
provide a prospectus for how to improve theory and observations going
forward. Recent advancements in analytical techniques create new
opportunities for partitioning E and T at the ecosystem scale, but their
assumptions have yet to be fully tested. For example, many approaches to
partition E and T rely on the notion that plant canopy conductance and
ecosystem water use efficiency exhibit optimal responses to atmospheric
vapor pressure deficit (D). We use observations from 240 eddy covariance flux
towers to demonstrate that optimal ecosystem response to D is a reasonable
assumption, in agreement with recent studies, but more analysis is necessary
to determine the conditions for which this assumption holds. Another
critical assumption for many partitioning approaches is that ET can be
approximated as T during ideal transpiring conditions, which has been
challenged by observational studies. We demonstrate that T can exceed 95 %
of ET from certain ecosystems, but other ecosystems do not appear to reach
this value, which suggests that this assumption is ecosystem-dependent with
implications for partitioning. It is important to further improve approaches
for partitioning E and T, yet few multi-method comparisons have been
undertaken to date. Advances in our understanding of carbon–water coupling
at the stomatal, leaf, and canopy level open new perspectives on how to
quantify T via its strong coupling with photosynthesis. Photosynthesis can be
constrained at the ecosystem and global scales with emerging data sources
including solar-induced fluorescence, carbonyl sulfide flux measurements,
thermography, and more. Such comparisons would improve our mechanistic
understanding of ecosystem water fluxes and provide the observations
necessary to validate remote sensing algorithms and land surface models to
understand the changing global water cycle.
Ideas and perspectives: Is dark carbon fixation relevant for oceanic primary production estimates?
Authors: Baltar Federico , Herndl Gerhard J.
Published: October 2019

Abstract. About half of the global primary production (PP) is generated in
the euphotic layer of the ocean. The 14C method developed by
Steemann Nielsen (Nielsen, 1952) more than half a century
ago has been the most frequently used method to determine PP in all aquatic
systems. This method includes dark incubations to exclude the
non-phototrophic dissolved inorganic carbon (DIC) fixation. The presence of
significant dark DIC fixation rates has been habitually used to suggest the
inaccuracy of the 14C method to determine autotrophic phytoplankton
primary production. However, we suggest that the dark DIC fixation
rates should be incorporated into global oceanic carbon production estimates
since the total production of organic matter does not originate only from
photosynthesis but also from other processes such as chemoautotrophic and
anaplerotic processes. Here we analyzed data collected over almost 30 years
from the longest available oceanic time series and calculated that the
inclusion of dark DIC fixation would increase oceanic PP estimates by
5 %–22 % when total dark DIC fixation is included or by 2.5 %–11 % when only
considering the nighttime DIC fixation. We conclude that dark DIC fixation
should be included into global oceanic primary production estimates as it
represents newly synthesized organic carbon (ca. 1.2–11 Pg C yr−1)
available for the marine food web.

Published: October 2019

Abstract. Over the last decades, hypoxia in marine coastal environments have become more and more widespread, prolonged and intense. These hypoxic events have large consequences for the functioning of benthic ecosystems. They profoundly modify early diagenetic processes involved in organic matter recycling, and in severe cases, they may lead to complete anoxia and presence of toxic sulphides in the sediment and bottom water, thereby severely affecting biological compartments of benthic marine ecosystems. Within these ecosystems, benthic foraminifera show a high diversity of ecological responses, with a wide range of adaptive life strategies. Some species are particularly resistant to hypoxia/anoxia and consequently, it is interesting to study the whole foraminiferal community as well as species specific responses to such events. Here we investigated the temporal dynamics of living benthic foraminiferal communities (recognised by CellTracker™ Green) at two sites in the saltwater Lake Grevelingen in the Netherlands. These sites are subject to seasonal anoxia with different durations and are characterised by the presence of free sulphide (H2S) in the uppermost part of the sediment. Our results indicate that foraminiferal communities are impacted by the presence of H2S in their habitat, with a stronger response in case of longer exposure times. At the deepest site (34 m), one to two months of anoxia and free H2S in the surface sediment resulted in an almost complete disappearance of the foraminiferal community. Conversely, at the shallower site (23 m), where the duration of anoxia and free H2S was shorter (one month or less), a dense foraminiferal community was found throughout the year. Interestingly, at both sites, the foraminiferal community showed a delayed response to the onset of anoxia and free H2S, suggesting that the combination of anoxia and free H2S does not lead to increased mortality, but rather to strongly decreased reproduction rates. At the deepest site, where highly stressful conditions prevailed for one to two months, the recovery time of the community takes about half a year. In Lake Grevelingen, Elphidium selseyense and Elphidium magellanicum are much less affected by anoxia and free H2S than Ammonia sp. T6. We hypothesise that this is not due to a higher tolerance of H2S, but rather related to the seasonal availability of food sources, which could have been less suitable for Ammonia sp. T6 than for the elphidiids.
Temporally dependent effects of rainfall characteristics on inter- and intra-event branch-scale stemflow variability in two xerophytic shrubs

Published: October 2019

Abstract. Stemflow is important for recharging root-zone soil moisture in arid
regions. Previous studies have generally focused on stemflow volume,
efficiency and influential factors but have failed to depict stemflow
processes and quantify their relations with rainfall characteristics within
events, particularly for xerophytic shrubs. Here, we measured the stemflow
volume, intensity, funneling ratio and time lags to rain at two dominant
shrub species (Caragana korshinskii and Salix psammophila) and rainfall characteristics during 54 events at the
semiarid Liudaogou catchment of the Loess Plateau, China, during the
2014–2015 rainy seasons. The funneling ratio was calculated as the ratio
between stemflow and rainfall intensities at the inter- and intra-event scales.
Our results indicated that the stemflow of C. korshinskii and S. psammophila, on average, started at 66.2
and 54.8 min, maximized 109.4 and 120.5 min after rain began, and ended
20.0 and 13.5 min after rain ceased. The two shrubs had shorter stemflow
duration (3.8 and 3.4 h) and significantly larger stemflow intensities
(517.5 and 367.3 mm h−1) than those of rain (4.7 h and 4.5 mm h−1). As branch size increased, both species shared the
decreasing funneling ratios (97.7–163.7 and 44.2–212.0) and stemflow
intensities (333.8–716.2 and 197.2–738.7 mm h−1). Tested by the multiple correspondence analysis and
stepwise regression, rainfall amount and duration controlled stemflow volume
and duration, respectively, at the event scale by linear relations (p < 0.01). Rainfall intensity and raindrop momentum controlled stemflow
intensity and time lags to rain for both species within the event by linear or
power relationships (p < 0.01). Rainfall intensity was the key factor
affecting stemflow process of C. korshinskii, whereas raindrop momentum had the greatest
influence on stemflow process of S. psammophila. Therefore, rainfall characteristics had
temporally dependent influences on corresponding stemflow variables, and the
influence also depended on specific species.
Role of sublimation and riming in the precipitation distribution in the Kananaskis Valley, Alberta, Canada
Authors: Poirier Émilie , Thériault Julie M. , Leriche Maud
Published: October 2019

Abstract. The phase of precipitation and its distribution at the surface can affect water resources and the regional water cycle of a region. A field project was held in March–April 2015 on the eastern slope of the Canadian Rockies to document precipitation characteristics and associated atmospheric conditions. During the project, 60 % of the particles documented were rimed in relatively warm and dry conditions. Rain–snow transitions also occurred aloft and at the surface in sub-saturated conditions. Ice-phase precipitation falling through a saturated atmospheric layer with temperatures > 0 ∘C will start melting. In contrast, if the melting layer is sub-saturated, the ice-phase precipitation undergoes sublimation, which increases the depth of the rain–snow transition. In this context, this study investigates the role of sublimation and riming in precipitation intensity and type reaching the surface in the Kananaskis Valley, Alberta, during March–April 2015. To address this, a set of numerical simulations of an event of mixed precipitation observed at the surface was conducted. This event on 31 March 2015 was documented with a set of devices at the main observation site (Kananaskis Emergency Services, KES), including a precipitation gauge, disdrometer, and micro rain radar. Sensitivity experiments were performed to assess the impacts of temperature changes from sublimation and the role of the production of graupel (riming) aloft in the surface precipitation evolution. A warmer environment associated with no temperature changes from sublimation leads to a peak in the intensity of graupel at the surface. When the formation of graupel is not considered, the maximum snowfall rate occurred at later times. Results suggest that unrimed snow reaching the surface is formed on the western flank and is advected eastward. In contrast, graupel would form aloft in the Kananaskis Valley. The cooling from sublimation and melting by rimed particles increases the vertical shear near KES. Overall, this study illustrated that the presence of graupel influenced the surface evolution of precipitation type in the valley due to the horizontal transport of precipitation particles.
A REVIEW OF MODELLING APPROACHES ON TIDAL ANALYSIS AND PREDICTION

Published: October 2019

Abstract. Tide height depends on both long-term astronomical effects that are principally affected by the moon and sun and short-term meteorological effects caused by severe weather conditions which are very important tasks for human activities, safe marine navigation in shallow areas, oceans and coastal engineering work. Conventional tidal forecasting techniques are based on harmonic analysis, which is a superposition of many sinusoidal constituents with three parameters amplitudes, Phase and frequencies using the least squares method to determine the harmonic parameters. However, harmonic analysis required a large number of parameters and long-term tidal measured for precise tidal level predictions. Furthermore, what seems to stand out by the other researchers on traditional harmonic methods, was its limitation when short data are involved and rely on based on the analysis of astronomical components and they can be insufficient when the influence of non-astronomical components such as the weather, is important. Therefore, conventional harmonic analysis alone does not adequately predict the coastal water level variation, in order to deal with these situations and provide predictions with the desired accuracy, with respect to the length of the available tidal record, an alternative approach has been developed by various tidalist. In this study the state - of - art for tidal analysis and prediction techniques that have proven to be successful in a variety of circumstances have been reviewed in a systematic and consistent way for holistic understanding with a view to provide a reference for future work, showing their main mathematical concepts, model capabilities for tidal analysis and prediction with their limitations.
EFFECTIVENESS OF CLASSIFICATION METHOD AND COLOR SYMBOL SCHEME ON CHOROPLETH MAP OF POPULATION DENSITY IN SPECIAL REGION OF YOGYAKARTA
Authors: 'Afifah Z. N. ,   Sudaryatno
Published: October 2019

Abstract. The need for presenting information in maps is increasingly high in various scientific fields. All scientific fields need to present effective data for decision making. Good decision making based on maps requires good understanding but not all scientific fields are familiar with using maps. Supporting factors for easy maps to understand are classification method and color symbol scheme. The purpose of this study was to select and test the classification method and the most effective color symbol scheme for mapping population density in the Special Region of Yogyakarta. The classification methods used in this study are constant interval, arithmetic progression, geometric progression, quantile, standard deviation and dispersal graph. The effectiveness test method for the most effective classification method is the proportion assessment. The color symbol scheme used in this study is a sequential color scheme, diverging color schemes, Corel Draw color schemes and color symbol schemes provided in ArcMap 10.3 software. The effectiveness test method for the most effective color symbol scheme is conventional eye tracking. The results showed that according to the proportion test the most effective classification method was the arithmetic interval classification method with results of 0.26. The most effective color symbol scheme in accordance with the effectiveness test using the conventional eye tracking method shows that the most effective color symbol scheme is a diverging color scheme. The important aspects to consider are average answering duration of 8.15 seconds, the accuracy of the answer is 98.9%, and easiness level of symbolization readings is 341. This research can be one of the references on the most effective classification method and reference regarding the selection of the most effective color symbol scheme on Choropleth Map of Population Density in Special Region of Yogyakarta, so that further research can continue the analysis of appropriate classification methods for demographic data. The method discussed in this study is also expected to be applicable to other data.

Published: October 2019

Abstract. Videogrammetry is a technique to generate point clouds by using video frame sequences. It is a branch of photogrammetry that offers an attractive capabilities and make it an interesting choice for a 3D data acquisition. However, different camera input and specification will produce different quality of point cloud. Thus, it is the aim of this study to investigate the quality of point cloud that is produced from various camera input and specification. Several devices are using in this study such as Iphone 5s, Iphone 7+, Iphone X, Digital camera of Casio Exilim EX-ZR1000 and Nikon D7000 DSLR. For each device, different camera with different resolution and frame per second (fps) are used for video recording. The videos are processed using EyesCloud3D by eCapture. EyesCloud3D is a platform that receive input such as videos and images to generate point clouds. 3D model is constructed based on generated point clouds. The total number of point clouds produced is analyzed to determine which camera input and specification produce a good 3D model. Besides that, factor of generating number of point clouds is analyzed. Finally, each camera resolution and fps is suggested for certain applications based on generated number of point cloud.
Spatial and temporal variations in basal melting at Nivlisen ice shelf, East Antarctica, derived from phase-sensitive radars

Published: October 2019

Abstract. Thinning rates of ice shelves vary widely around Antarctica, and basal
melting is a major component of ice shelf mass loss. In this study, we
present records of basal melting at a unique spatial and temporal resolution
for East Antarctica, derived from autonomous phase-sensitive radars. These
records show spatial and temporal variations of basal melting in 2017 and
2018 at Nivlisen, an ice shelf in central Dronning Maud Land. The annually
averaged basal melt rates are in general moderate (∼0.8 m yr−1).
Radar profiling of the ice shelf shows variable ice thickness from smooth
beds to basal crevasses and channels. The highest basal melt rates (3.9 m yr−1) were observed close to a grounded feature near the ice shelf front. Daily time-varying measurements reveal a seasonal melt signal 4 km
from the ice shelf front, at an ice draft of 130 m, where the highest daily
basal melt rates occurred in summer (up to 5.6 m yr−1). In comparison
with wind, air temperatures, and sea ice cover from reanalysis and satellite
data, the seasonality in basal melt rates indicates that summer-warmed ocean
surface water was pushed by wind beneath the ice shelf front. We observed a
different melt regime 35 km into the ice shelf cavity, at an ice draft of
280 m, with considerably lower basal melt rates (annual average of 0.4 m yr−1) and no seasonality. We conclude that warm deep-ocean water at
present has a limited effect on the basal melting of Nivlisen. On the other
hand, a warming in surface waters, as a result of diminishing sea ice cover,
has the potential to increase basal melting near the ice shelf front.
Continuous in situ monitoring of Antarctic ice shelves is needed to
understand the complex mechanisms involved in ice shelf–ocean
interactions.
Numerals under negation: Empirical findings
Authors: Solt Stephanie , Waldon Brandon
Published: October 2019

Despite a vast literature on the semantics and pragmatics of cardinal numerals, it has gone largely unnoticed that they exhibit a variety of polarity sensitivity, in that they require contextual support to occur felicitously in the scope of sentential negation. We present the results of a corpus analysis and two experiments that demonstrate that negated cardinals are acceptable when the negated value has been asserted or otherwise explicitly mentioned in the preceding discourse context, but unacceptable when such a value is neither mentioned nor inferable from that context. In this, bare cardinals exhibit both similarities to and differences from other types of numerical expressions. We propose an account of our findings based on the notion of convexity of linguistic meanings (Gärdenfors 2004) and discuss the implications for the semantics of numerical expressions more generally.

Geen bancair klantonderzoek op verzoek van het OM: aandachtspunten voor een vrijwaring voor het niet-naleven van de wet

Het OM verzoekt banken steeds vaker om geen klantonderzoekshandelingen, ook wel know your customer- of KYC-handelingen, ten opzichte van een bepaalde klant te verrichten. Dergelijke handelingen zouden in bepaalde gevallen namelijk schadelijk kunnen zijn voor het strafrechtelijk onderzoek. Als een bank bereid is om aan zo’n verzoek van het OM mee te werken, loopt die bank verschillende risico’s op strafrechtelijke aansprakelijkheid. Het OM kan deze risico’s afdekken door de bank hiervoor strafrechtelijk te vrijwaren. In de praktijk neemt het uitonderhandelen van de vrijwaringstekst nog vaak veel tijd in beslag. Een standaardvrijwaring zou dit probleem oplossen.

The Use of LIF-based Instrument with 405 nm for Real-time Monitoring of Aerosolized Bio-particles
Authors: Yoon Sung Nyo , Lee Jaekyung , Kim Duckho , Yoo Hyun Sang , Min Kyung Yool , Kim Min Cheol
Published: October 2019

Bio-aerosols can affect public health depending on the origin of bio-particles (bacteria, virus etc.). Here, we attempted to assess the applicability of laser-induced fluorescence (LIF) instrument with 405 nm to real-time monitoring of bacteria and viruscontaining aerosols. For the purpose, the LIF-based BDS (Bio-aerosol Detection System) was used. The bio-particle monitoring of the BDS is based on fluorescence signals from two wavelength ranges [short wavelength range (SWR): 430–550 nm & long wavelength range (LWR): 500–600 nm] and the scattering signal. Firstly, auto-fluorophores (NADH, riboflavin, tyrosine, tryptophan) were tested to expect the monitoring ranges of the BDS for the auto-fluorophores. NADH and riboflavin showed fluorescence signals from two wavelength ranges, and the fluorescence efficiency of NADH was higher in the SWR than in the LWR and that of riboflavin was reversed. While tyrosine and tryptophan showed negligible fluorescence signals from two wavelength ranges as expected. Next, the lyophilized powders of Bacillus subtilis (BS), virus vaccines [ND (Newcastle Disease), IB (Infectious Bronchitis)] and the bacteriophage MS2 were tested to investigate the monitoring ranges of the BDS for the bio-particles. Individual virus and bacteriophage have been expected no fluorescence signals because of the absence of NADH and riboflavin fluorescing by 405 nm. Nonetheless, all the tested samples showed the fluorescence signals in the size range of 2 to 15 μm, generally known as bio-aerosol size. Considering that atmospheric virus particles are released through the respiratory organs of their hosts, just as virus vaccines from chicken embryo and MS2 from E. coli, it can be thought in turn that the BDS can also monitor bio-aerosols including virus as well as bacteria. Taken together, we suggests that the BDS, LIF-based instrument with 405 nm, is applicable for real-time monitoring of virus-containing aerosols as well as other bio-aerosols by counting the fluorescence particles and resolving their particle sizes.
Genetic determinants of resistance to highly pathogenic avian influenza in chickens
Authors: Drobik-Czwarno Wioleta , Wolc Anna , Kucharska Kornelia , Martyniuk Elżbieta
Published: October 2019

Highly pathogenic avian influenza (HPAI) poses a huge threat to poultry production and also introduces an epidemiological risk in the human population. Thus far, HPAI has been controlled mainly through widespread implementation of biosecurity, and in the case of an outbreak, liquidation of flocks and establishment of protection zones. Alternative strategies for combating HPAI include the use of vaccines, genetic modification, and genetic selection for increased general and specific immunity in birds. These kinds of strategies often require identification of the genes involved in the immune response to the pathogen. Many genes have been identified as potentially associated with differences in the response to HPAI between poultry species and between individuals. Thus far, the most attention has been focused on genes taking part in regulating the innate immune response, which is responsible for preventing infection and limiting the replication and spread of the virus. The most commonly mentioned candidates for layer chickens include interferon-stimulated genes (ISGs) and RIG-I-like receptors. Proteins encoded by genes of the BTLN family, defensins, and proteins involved in apoptosis have also been associated with differences in the response to HPAI. Recent years have seen an increasing number of studies on the genetic determinants of individual differences in the response to HPAI in chickens. Data from HPAI outbreaks in the US in the spring of 2015 and Mexico in the years 2012-2016 have enabled a more precise analysis of this problem. A number of genes have been identified as associated with the immune response, but their specific role in determining the survival of birds requires further study. Preliminary results indicate that genetic determinants of resistance to HPAI are highly complex and can vary depending on the virus strain and the genetic line of birds.
Dependence of the frequency of sperm defects and dimensions on sperm motility in ejaculates of Polish Landrace boars
Authors: IWANINA Maria , KONDRACKI Stanisław
Published: October 2019

An attempt was made to determine the dependence of the frequency of sperm defects and dimensions on sperm motility in ejaculates of Polish Landrace boars. The study was conducted on 393 ejaculates collected from 33 Polish Landrace boars. Ejaculates were grouped according to the percentage of sperm with progressive motility, distinguishing ejaculates in which the percentage of motile sperm was 70% and 80%. In each ejaculate, the frequency of morphological changes in the sperm was determined and morphometric measurements of the sperm were made. Ejaculates with a higher proportion of sperm with progressive motility were found to contain more sperm. The ejaculate volume and sperm concentration in the ejaculate were not found to be directly associated with sperm motility. The frequency of primary defects was linked to sperm motility. Ejaculates with higher sperm motility contained fewer sperm with primary defects. The frequency of minor morphological changes, however, shows no significant dependence on sperm motility in the ejaculate. The primary morphological sperm defects most often found in ejaculates are a proximal droplet and the Dag defect. Both of these morphological forms are more common in ejaculates with lower sperm motility. The most common secondary sperm defects include sperm with a simple bent tail, sperm with a free normal head, and sperm with a distal droplet. These defects were not found to depend on sperm motility in the ejaculate. Sperm cells in ejaculates with greater sperm motility had slightly larger dimensions than sperm in ejaculates with lower sperm motility. Ejaculates with higher sperm motility are preferable for use in practice, not only because more insemination portions can be prepared from them, but also due to the lower frequency of primary defects.

Engaging a Wider Audience: Reflections on Walter Gulick’s Recovering Truths
Authors: Bernal Ellen W. ,   The Polanyi Society
Published: October 2019

Michael Polanyi’s thought still has an “outsider” status, despite the efforts of The Polanyi Society and extensive publications by other scholars in various fields. Gulick attributes this limited familiarity to Polanyi’s complexity and atypical philosophical insights, his re-introduction of the personal in feats of knowing, and his call for significant intellectual reform. Gulick sets out to remedy the situation with his well written, comprehensive, and accessible anthology. Polanyi’s thought can be applied to many of today’s concerns, including human research, animal intelligence, ecoliterature, and socio-political problems. Gulick’s book is an excellent resource for introducing students and others to the relevance of Polanyi’s thought for today’s issues.

Published: October 2019

This well-organized collection offers a blueprint for tracing continuity in Polanyi’s lifelong intellectual output. Gulick’s Recovering Truths: A Comprehensive Anthology of Michael Polanyi’s Writings makes it possible for anyone interested in Polanyi’s writings to explore the overall philosophical stance from which Polanyi’s thought originates. In addition to key texts from Polanyi’s ouvre, the volume introduces the reader to the method by which Polanyi’s philosophy transcends disciplinary preoccupations and transforms the post-Cartesian intellectual terrain through the conceptual tools of a post-critical philosophy.

Neste estudo propõe-se conhecer a dinâmica da vegetação de Cerrado e Floresta Estacional, no período de 2000 a 2017, na Área de Preservação Ambiental (APA) Lago de Palmas, utilizando-se imagens do satélite Landsat e o software livre Spring 5.5.3. Foram construídos dois mapas temáticos da área estudada para estimar, por meio de análise comparativa, o processo de substituição da vegetação nativa, utilizaram-se os métodos Maxver e Isoseg para as classes de cobertura da terra: Vegetação nativa – Mata densa, Vegetação nativa – Campo, Solo exposto e Curso hídrico, na correção e validação recorreram-se às imagens históricas do Google Earth Pro. Os resultados indicam que houve uma perda de 38,56% da vegetação nativa, o centro urbano expandiu em uma proporção de 14 vezes, cerca de 10.760,13 ha foram inundados pelo reservatório da usina do Lajeado, resultando a perda de terra, árvores e biodiversidade. Infere-se que a APA não cumpre o papel previsto na legislação ambiental, pois sua ocupação é feita de forma desordenada, não existe plano de manejo, os mapeamentos indicam uma sistemática substituição da vegetação nativa por massa d’água, áreas agrícolas e de urbanização.

A bacia hidrográfica do rio Machadinho é um exemplo de ocupação desordenada presente na região amazônica, na qual foram desmatadas grandes áreas com consequente conversão da floresta em pastagens e em núcleos urbanos. O presente trabalho tem o objetivo de analisar os impactos na hidrologia (vazão, precipitação e evapotranspiração) da bacia do rio Machadinho diante de sua dinâmica de ocupação antrópica. Primeiramente, analisaram-se mudanças na cobertura da terra usando imagens do sensor Landsat 5-TM para os anos 1984, 1997 e 2011. A variável vazão foi avaliada quanto a sua sensibilidade mediante o emprego do modelo SWAT para determinar a descarga líquida fixando-se os padrões climáticos e variando-se os cenários históricos de cobertura da terra. A precipitação, obtida por meio de dados do CHIRPS para o período de 1981 a 2017, e a evapotranspiração, estimada via dados do SSEBop entre os anos de 2002 a 2017, foram tratadas como variáveis geoespaciais distribuídas na bacia, com tendências de comportamento de suas séries históricas aferidas por meio do teste Mann-Kendal. Os resultados obtidos mostraram que a ocupação da bacia deu-se de maneira desordenada, cuja área com pastagem passou de 2,6% no ano de 1984 para 45,9% no ano de 2011, sendo a maior conversão observada na nascente do corpo hídrico principal, o que evidenciou uma maior produção de vazão pelo modelo SWAT, que adequadamente captou a variação dessa variável. Adicionalmente, observou-se tendência de redução pluviométrica nos meses mais chuvosos, enquanto detectou-se elevação da evapotranspiração nos meses mais quentes. Nesse sentido, é importante ressaltar que o desmatamento da região tende a reduzir a disponibilidade hídrica para a bacia.

Este trabalho teve por objetivo avaliar se diferentes doses de calcário, aplicadas em subsuperfície, influenciam a absorção de nutrientes em plantas de pinhão-manso (Jatropha curcas L.) em desenvolvimento inicial. O experimento foi realizado em vasos e sob condição de casa de vegetação, em que as plantas de pinhão-manso foram cultivadas em vasos de PVC, divididos em camada superficial (0-20 cm) e camada subsuperficial (20-60 cm). A camada superficial recebeu solo corrigido (11,1 t ha-1 de CaCO3 e MgCO3) e adubação com NPK. Na camada subsuperficial foi adicionado ao solo as doses de 0; 3,7; 5,6; 7,4; 11,1 e 14,9 t ha-1 de CaCO3 e MgCO3 na relação molar 4:1. Após 120 dias da emergência das plantas, avaliaram-se os teores e conteúdos de Al, P, K, Ca, Mg, Zn, Mn, Fe e Cu nas folhas, no caule e nas raízes. Em plantas de pinhão-manso, os teores de Al são maiores nos tecidos radiculares, seguido das folhas e do caule. Os teores e os conteúdos de P, K, Ca, Mg, Zn e Mn no tecido vegetal são influenciados pelo aumento das doses de calcário no solo. Os teores de Fe e Cu nos tecidos vegetais de pinhão-manso sofrem pouca influência das doses crescentes de calcário em subsuperfície.

Published: October 2019

O Atualmente vivemos inúmeras transformações, percebe-se que o estilo de vida das pessoas, vem provocando modificações. Um exemplo bastante atual dessas modificações são os resíduos sólidos, que vem comprometendo a qualidade ambiental, e, a qualidade de vida do homem a julgar pelos impactos socioeconômicos, sanitários e ambientais a eles inerentes. Os resíduos dos serviços de saúde (RSS) se inserem dentro desta problemática e vêm assumindo grande importância nos últimos anos. Esta preocupação cresceu devido ao conhecimento sobre os riscos impostos à saúde pública e ao meio ambiente. O presente estudo objetivou apresentar alternativas tecnológicas no tratamento e na disposição final utilizados na gestão de RSS. Trata-se de um estudo descritivo simples, de cunho bibliográfico. A coleta de dados, foi alcançada por meio de informações junto à bibliotecas eletrônicas. Percebe-se, no entanto que, existem inúmeras tecnologias de tratamento de RSS, com diferentes características, em termos de custos, segurança ao meio ambiente e à população, entre outros. Nota-se que aqueles processos que apresentam custo baixo, não são considerados seguros e biodegradáveis e que há necessidade de conhecer todas as características desses processos para que haja uma escolha do tratamento mais adequado, podendo variar essa adequação.
Dewey, Ford e Monteiro Lobato: Os princípios da eficiência e da continuidade no olhar da filosofia e da literatura
Authors:   professor udesc, matos José claudio morelli
Published: October 2019

O artigo discute a representação da pessoa e da obra de Henry Ford, no romance O Presidente Negro de Monteiro Lobato. Pela interpretação do texto literário, formula o ideário fordista com o princípio da eficiência. Propõe criticamente o princípio da continuidade, originário da filosofia de John Dewey, como alternativa ao fordismo, para fundamentar a reflexão sobre a educação e a vida social. Emprega a literatura como instrumento de reflexão e atribuição de significado, conforme a teoria deweyana da continuidade entre a experiência estética e intelectual. As conclusões têm relevância para as questões sociais e educacionais da contemporaneidade, além de abrir um campo de estudos sobre a função da literatura em uma forma de educação que promova o crescimento da vida compartilhada. Formula, a partir de Dewey, uma crítica ao fordismo e às formas mecanicistas de organização da vida social, incluindo a educação.

Published: October 2019

Este artigo busca identificar as contribuições das Exposições Universais para a disseminação de padrões na joalheria da segunda metade do século XIX, posto que tais eventos foram palco para demonstrações dos ideais de progresso e avanços tecnológicos vigentes no século XIX, além de terem sido o espelho dos valores e gostos da elite da Europa oitocentista. Analisaremos, sob a perspectiva da Cultura Material, considerando a produção, circulação e usos dos objetos, documentos textuais e visuais das Exposições Universais realizadas em Londres em 1851 e 1862, bem como da Exposição de Paris de 1889. A partir dos relatórios do júri buscaremos identificar quais foram os critérios utilizados para a escolha das joias premiadas em cada Exposição, bem como quem eram os principais joalheiros expositores e suas características. A partir dos catálogos e jornais ilustrados das Exposições buscaremos compreender a visualidade das joias, formas e materiais. Ao utilizarmos as Exposições Universais como fonte para o estudo da joalheria, pretendemos contribuir para uma aproximação interdisciplinar do estudo da história da moda.

El presente estudio caso-controle, doble ciego, y prospectivo investigó los efectos del entrenamiento musical de numerosidad (NMT; Numeracy Musical Training), sobre habilidades cognitivas en niños de enseñanza primaria. Participaron 42 niños de 8 a 10 años divididos en dos grupos: con Bajo Rendimiento Aritmético (n = 21), y con Medio Rendimiento Aritmético (n = 21). Los niños pasaron por dos evaluaciones, antes y después de la realización del NMT, en las cuales se aplicaron pruebas cognitivas y escalas de comportamiento, que evaluaban variables tales como: rendimiento escolar, CI, memoria operativa, cognición numérica, ansiedad y estrés. El NMT fue desarrollado en ocho sesiones colectivas y tuvo como objetivo estimular los sistemas de la cognición numérica e integrar conocimientos musicales básicos y representaciones simbólicas. Después de la intervención por medio del entrenamiento musical los niños de ambos grupos obtuvieron mejoras significativas en el rendimiento académico, en los sistemas de la cognición numérica y en la memoria operativa, así como una disminución de la manifestación de ansiedad a las matemáticas.

The present case-control, double-blind, and prospective study investigated the effects of Numeracy Music Training (NMT) on cognitive skills of primary school children. Participating in the study were 42 children aged 8 to 10 years divided into two groups: Low Achievement in Math (n = 21), and Average Achievement in Math (n = 21). The children underwent two evaluations before and after NMT, where cognitive tests and behavior scales were applied that assessed variables such as school performance, IQ, working memory, numerical cognition, anxiety and stress. NMT was developed in eight group sessions and aimed to stimulate the systems of numerical cognition and integrate basic musical knowledge, and symbolic representations. After the intervention, through musical training, the children in both groups showed significant improvements in school performance, systems of numerical cognition and working memory, as well as the reduction of manifestation of mathematics anxiety.
