Authors: Chernyuk Vladimir D. , Kukharchyk Tamara I. , Kazyrenka Marharyta I.
Published: November 2021

Soil pollution in the impact zones of enterprises for the collection and processing of electronic and electrical equipment (EEE) wastes is caused by the chemicals they contain. The article presents the results of studying the content of heavy metals in soils and technogenic substrates selected in the impact zones of enterprises for the production of EEE and waste processing, located in the city of Minsk, Belarus. A total of 15 soil samples and 13 samples of technogenic deposits were taken and analyzed. Atomic absorption spectroscopy (AAS) was used in chemical analytical tests. Statistical parameters of the content of heavy metals are presented, their comparison with published data is done. It is shown that the obtained average concentrations of cadmium and lead in the soils of the investigated enterprises are
1.2–1.5 times, and copper and zinc are 2.7–4.6 times higher than those for the industrial zones of Minsk. The maximum
concentrations of heavy metals were detected in samples of technogenic deposits containing waste impurities, including
plastic particles. On the example of other countries, the importance of EEE plastic waste as a source of soil contamination
is shown.

Published: November 2021

Knowledge about structure and rheological peculiarities of drilling solutions and reagents applied for the proceeding of oil wells has significant value for the forecasting of oil wells drilling. The research results of the structure of the humic substances of peat and brown coals precipitated in different pH ranges from the standpoint of their ability to structure formation on the base of the rheological curves obtaining of the flow of their dispersions

and determining of their rheological parameters in terms of their application in drilling practice are given in the article. It is established that during transition from fraction, beset into alkaline media (12.0–8.5) to fraction beset into acid media (5.0–2.0) the decrease of the rheological indicators of caustobiolate humic substance is occurred. Rheological curves of the flow of the disperse of caustobiolate humic substances of the fraction 1 and 2 are characterized for strong fossil structures, disperses of humic substances of the fraction 3 is for less strong coagulation structures. Less structured are humic substances of brown coal so that their use is preferable for the regulation of the structure and rheological peculiarities of drilling solutions.
GEOECOLOGICAL ASSESSMENT OF SUITABILITY OF URBAN WASTEWATER SLUDGE FOR VARIOUS USES (ON THE EXAMPLE OF BREST REGION)
Authors: Basalai Ekaterina N.
Published: November 2021

The article considers the results of studies of the composition and properties of urban wastewater sludge (UWWS) of treatment facilities in 9 different cities of Brest region in three groups of indicators: agrochemical, microbiological, and heavy metal content. A comparison of the data obtained for UWWS with similar indicators for local soils, literature data on the properties of UWWS, comparison with the regulatory requirements for UWWS in the Russian Federation, the EU, the USA, etc. is presented. Shown that with the high fertilizing potential of UWWS in cities of Brest

region, due to high content of organic and nutrient substances (nitrogen, phosphorus, potassium), the use of UWWS in

agriculture is limited by its microbiological contamination and high concentrations of heavy metals (zinc, copper, nickel,

chromium), exceeding maximum permissible concentrations established by the requirements for UWWS in the Russian

Federation and other countries. Based on the results obtained and the review given in the article about the ways of handling

UWWS in different countries of the world, an assessment of the suitability of UWWS in cities of Brest region and Belarus as a whole for various types of use is given. With insufficient development of regulatory and legal regulation in the field of the management of UWWS, the most acceptable methods for the conditions of Belarus for the management of UWWS in the medium term are their use for the reclamation of disturbed land, as an insulating layer in landfills of solid municipal waste, in urban and forestry (in floriculture, in parks, squares, nurseries, etc.), and also anaerobic digestion with the production of organic fertilizers and energy.

QUEJAS EN MATERIA TRIBUTARIA: EVOLUCIÓN, PERSPECTIVAS Y OPORTUNIDADES. (PARTE II) 1
Authors: Jesús Rodrigo Fernández
Published: November 2021

Las quejas en materia tributaria existen en el Derecho español desde 1881. Son poco conocidas y, por ello, poco valoradas, como modo de defensa de los derechos de los ciudadanos. En la actualidad incluyen las que se refieren a la efectividad de los derechos de los obligados tributarios, a la calidad de los servicios de las Administraciones en el ámbito tributario y, en especial, las que se producen por la aplicación del sistema tributario. No sustituyen a los recursos administrativos, pero pueden evitarlos, colaborando a disminuir la alta litigiosidad que existe en España en materia fiscal, que es uno de sus principales problemas, que sigue pendiente de resolver. Se estudian las Instituciones y órganos internos que las atienden a nivel de la Administración del Estado, Comunidades Autónomas y Corporaciones Locales. También se estudia la actividad del Defensor del Pueblo en materia fiscal y el grado de coordinación que existe entre las diferentes vías de presentación de quejas. Finalmente se resumen las propuestas que se han hecho para mejorar su efectividad, su grado de aplicación y como pueden utilizarse para una mejor defensa de los derechos de los contribuyentes, mejora de la eficiencia de la Administración y defensa del interés público.

Effect of Flow Rate on the Corrosion Behavior of API 5L X80 Steel in Water-Saturated Supercritical CO2 Environments
Authors: da Silva de Sá Jonas , Ma Wenlong , Owen Joshua , Hua Yong , Neville Anne , Ponciano Gomes José A.C. , Barker Richard
Published: November 2021

The effect of the water-saturated supercritical carbon dioxide (scCO2) flow rate on the corrosion behavior of API 5L X80 steel at a temperature of 35°C and pressure of 80 bar was investigated. Tests were performed with the samples attached to a rotating shaft inside an autoclave. Results indicate that increasing the scCO2 flow rate had no significant influence on the general/localized corrosion rate under the various dynamic conditions considered. The average general corrosion rate was 0.064 mm/y, while the average measured pitting penetration rates were one order of magnitude higher. The size of the corrosion features on the surface of the samples, which were believed to provide an indication as to the size of the condensed water droplets, was much smaller than the calculated critical droplet size needed to be displaced by the flow, supporting the theory as to why flow rate had little effect on the corrosion response.

Published: November 2021

Diante da pandemia do COVID-19, instaurada com a propagação do Sars-CoV-2, o presente artigo estuda o reconhecimento de um dever humano de promoção da saúde, no âmbito Internacional, pelas transportadoras aéreas comerciais de passageiros no embarque, desembarque e voo internacional. Para tanto, por meio do método dialético e à luz Teoria Internacional dos Deveres Humanos, analisam-se os principais tratados internacionais relacionados à aviação comercial, tais quais: a Convenção Internacional da Aviação Civil (1944) e, a Convenção para a Unificação de Certas Regras Relativas ao Transporte Aéreo Internacional (1999), bem como documentos de ordem sanitária concernentes à aviação internacional. Assim, restou clara a existência do dever humano pesquisado. Posto isso, de maneira complementar, fez-se uma análise da extensão da onerosidade de tal dever, buscando apresentar alternativas para seu custeamento em uma lógica de sociedade democrática pautada no pilar da solidariedade. Finalmente, busca-se contribuir com a esfera jurídica da aviação civil internacional em momentos de crises sanitárias motivadas por pandemias – e em seus posteriores períodos de normalidade -, estabelecendo balizas hermenêuticas para a interpretação das codificações internacionais relacionadas ao tema e, iniciando uma discussão acerca da extensão e distribuição da onerosidade decorrente do dever humano analisado.
Proteção da inovação pela aplicação do Direito da Concorrência da União Europeia: análise da indústria farmacêutica
Authors: Leurquin Pablo
Published: November 2021

A oposição entre a defesa da concorrência e os direitos de propriedade intelectual, ou a abstrata complementariedade entre essas normas jurídicas, não são suficientes para resolver os desafios da interface entre esses ramos do Direito. Entende-se que estes desafios devem ser avaliados em setores específicos e em um determinado ordenamento jurídico. O objetivo desse artigo é investigar como o Direito da Concorrência da União Europeia tem sido aplicado para punir comportamentos abusivos de empresas detentoras de direitos de propriedade intelectual. A indústria farmacêutica foi selecionada para ser analisada, sobretudo, por causa da recorrente instrumentalização das patentes para excluir a entrada de genéricos no mercado. Foi realizado levantamento dos principais julgados de órgãos europeus de defesa da concorrência, com intuito de avaliar as suas contribuições na proteção da inovação. Foi constatado que o modelo europeu consolidou a importância das autoridades de defesa da concorrência em casos envolvendo direitos de propriedade intelectual.

Access to and use of parks is associated with physical activity participation. Our Voice is a systematic method blending community-based participatory research (CBPR) and citizen science. As part of a comprehensive, mixed-methods study in St. Louis, Missouri (PARCS), we tested the feasibility of the Our Voice method for gathering community input on the barriers to and facilitators of accessibility and use of large metropolitan parks, by describing the implementation of the Our Voice method among recreational and commuter users of a large metropolitan park in St. Louis, MO. Due to challenges posed by COVID-19, the Our Voice methodology was adapted for remote participation. Twenty-three citizen scientists (14 recreational park users and 9 commuters) collected and analyzed geolocated route, photo, and audio or text data on facilitators and barriers to park use and access. They identified 6 priority themes and 12 solution ideas, and presented them to stakeholders. In contrast to previous Our Voice studies, separate user groups (recreation and commuter users) independently prioritized many of the same themes. Adaptation of the Our Voice protocol to virtual practices during COVID-19 revealed positive implications for cost, reach, and scale of studies grounded in CBPR and citizen science. We provide a set of recommended practices for using Our Voice as a method to evaluate and promote equity of access and use of metropolitan parks.

Published: November 2021

Introduction: Interventions targeting multiple levels of influence and settings may have a greater impact on children’s total daily physical activity than those targeting a single setting. This study evaluated the addition of family supports to a classroom-based physical activity intervention.

Methods: 6 schools were randomized to a remotely delivered classroom-based physical activity only (CBPA) or classroom-based physical activity plus family (CBPA+) arm. The latter added behavior change tools (e.g., self-regulation) delivered via text messages and newsletters to caregiver/child dyads. The intervention lasted for 7 weeks with a 1-week baseline and 1-week post-intervention assessment (9 weeks total). Children who enrolled in the evaluation study received a Garmin activity monitor, which was used to tailor the text messages and evaluate changes in moderate to vigorous physical activity (MVPA). Caregivers completed surveys evaluating intervention acceptability.

Results: The 53 child participants (CBPA n=35; CBPA+ n=18) were 9.7±0.7 years old, 64% were female, 59% were Black, and 23% were Hispanic/Latinx. Almost 90% of caregivers reported high satisfaction with the added family-based intervention content. Adherence to wearing the Garmin was higher in the CBPA+ arm. MVPA was low at baseline and during the first 3 weeks of the intervention (CBPA 7.5±3.1 minutes/day; CBPA+ 7.9±2.7 minutes/day) and increased by ~45 min/day by weeks 6-8 (CBPA 56.8±34.2 minutes/day; CBPA+ 49.2±18.7minutes/day). Changes in MVPA were similar between arms.

Conclusion: The high acceptability and intervention engagement in the CBPA+ arm show promise for integrating mHealth tools to provide additional family support in multilevel multiapproach interventions targeting children’s physical activity.

Tracking the influence of cloud condensation nuclei on summer diurnal precipitating systems over complex topography in Taiwan
Authors: Chang Yu-Hung , Chen Wei-Ting , Wu Chien-Ming , Moseley Christopher , Wu Chia-Chun
Published: November 2021

Abstract. This study focuses on how aerosols, serving as cloud
condensation nuclei (CCN), affect the properties of diurnal precipitation
under the weak synoptic weather regime over complex topography, which is a
common summertime environmental regime in Taiwan. Semi-realistic large-eddy
simulations (LESs) were carried out using TaiwanVVM and driven by idealized
observational soundings. We perform object-based tracking analyses, which
diagnose both the spatial and temporal connectivity of convective systems,
aiming to reduce the variability in convection and align the aerosol effects
on the mature stage of the convective life cycle. In the hotspot areas of
strong orographic locking processes, the precipitation initiation is
postponed significantly when the CCN concentration is increased from the
clean scenario to the normal scenario, which prolongs the development of
local circulation and convection. For this organized regime, the occurrence
of the tracked extreme diurnal precipitating systems is notably enhanced.
Also, the 99th percentile of the maximum rain rate, cloud depth, and in-cloud
vertical velocity during the lifetime of the diurnal precipitating systems
increases by 9.4 %, 4.4 %, and 1.3 %. This study demonstrates that
the design of semi-realistic LESs, as well as the object-based tracking
analyses, is useful to investigate the responses of orographically driven
diurnal convective systems to ambient conditions.
Observing electric field and neutral wind with EISCAT 3D
Authors: Stamm Johann , Vierinen Juha , Gustavsson Björn
Published: November 2021

Abstract. Measurements of height-dependent electric field (E) and neutral wind (u) are important governing parameters of the Earth's upper atmosphere, which can be used to study, for example, how auroral currents close or how energy flows between the ionized and neutral constituents. The new EISCAT 3D (E3D) incoherent scatter radar will be able to measure a three-dimensional ion velocity vector (v) at each measurement point, which will allow less stringent prior assumptions about E and u to be made when estimating them from radar measurements. This study investigates the feasibility of estimating the three-dimensional electric field and neutral wind vectors along a magnetic field-aligned profile from E3D measurements, using the ion momentum equation and Maxwell's equations. The uncertainty of ion drift measurements is estimated for a time and height resolution of 5 s and 2 km. With the most favourable ionospheric conditions, the ion wind at E region peak can be measured with an accuracy of less than 1 m/s. In the worst case, during a geomagnetically quiet night, the uncertainty increases by a factor of around 10. The uncertainty of neutral wind and electric field estimates is found to be strongly dependent on the prior constraints imposed on them. In the lower E region, neutral wind estimates have a lower standard deviation than 10 m/s in the most favourable conditions. In such conditions, also the F region electric field can be estimated with uncertainty of about 1 mV/m. Simulated measurements of v are used to demonstrate the ability to resolve the field-aligned profile of E and u. However, they can only be determined well at the heights where they dominate the ion drift, that is above 125 km for E and below 115 km for u. At the other heights, the results are strongly dependent on the prior assumptions of smoothness.
Accounting for surface waves improves gas flux estimation at high wind speed in a large lake
Authors: Perolo Pascal , Fernández Castro Bieito , Escoffier Nicolas , Lambert Thibault , Bouffard Damien , Perga Marie-Elodie
Published: November 2021

Abstract. The gas transfer velocity (k) is a major source of uncertainty when assessing the magnitude of lake gas exchange with the atmosphere. For the
diversity of existing empirical and process-based k models, the transfer velocity increases with the level of turbulence near the air–water
interface. However, predictions for k can vary by a factor of 2 among different models. Near-surface turbulence results from the action of wind
shear, surface waves, and buoyancy-driven convection. Wind shear has long been identified as a key driver, but recent lake studies have shifted the
focus towards the role of convection, particularly in small lakes. In large lakes, wind fetch can, however, be long enough to generate surface waves
and contribute to enhance gas transfer, as widely recognised in oceanographic studies. Here, field values for gas transfer velocity were computed in
a large hard-water lake, Lake Geneva, from CO2 fluxes measured with an automated (forced diffusion) flux chamber and CO2 partial
pressure measured with high-frequency sensors. k estimates were compared to a set of reference limnological and oceanic k models. Our analysis
reveals that accounting for surface waves generated during windy events significantly improves the accuracy of k estimates in this large lake. The
improved k model is then used to compute k over a 1-year time period. Results show that episodic extreme events with surface waves (6 %
occurrence, significant wave height > 0.4 m) can generate more than 20 % of annual cumulative k and more than 25 % of annual
net CO2 fluxes in Lake Geneva. We conclude that for lakes whose fetch can exceed 15 km, k models need to integrate the effect of
surface waves.
Development of forecast information for institutional decision-makers: landslides in India and cyclones in Mozambique
Authors: Budimir Mirianna , Sneddon Alison , Nelder Issy , Brown Sarah , Donovan Amy , Speight Linda
Published: November 2021

Abstract. There remains a gap between the production of scientifically robust forecasts, and the translation of these forecasts into useful information such as daily "bulletins" for decision-makers in early warning systems. There is significant published literature on best practice to communicate risk information, but very little to guide and provide advice on the process of how these bulletins have been, or should be, developed. This paper reviews two case studies where bulletins were developed for national and district-level government agencies and humanitarian responders: daily reports in response to Cyclones Idai and Kenneth in Mozambique, and prototype landslide forecast bulletins in Nilgiris and Darjeeling Districts of India. Primary data was collected from producers and intermediaries of the bulletins via interview, and secondary data analysed on: iterative changes in the bulletin development; minutes from internal discussions; and feedback from users to extract learning on both the content and process of developing the bulletins. There were significant similarities in the type of content included in the bulletins, such as the layout, choice of words, and use of visualisation that was consistent with published best practices. Both case studies experienced challenges dealing with uncertainty, complexity, and whether to include advice. There were also similarities in the processes and approaches taken to develop the bulletins. Both case studies took an iterative approach, developed feedback mechanisms, benefitted from experienced multi-disciplinary teams, emphasised the need for strong inter-relationships, and the importance and value of preparedness and protocols. A major challenge was the difficulty of balancing science capabilities with user needs, which did not become significantly easier to deal with given more time availability. The findings indicate that whilst more research is needed into existing or best practice processes to develop content for forecast bulletins, there is an existing body of experiential and intuitive knowledge and learning that already exists but is not yet captured in an appropriate format that could be of significant interest and value to those developing forecast information. This paper goes some way to capturing some of the learning from translating scientific forecasts into useful information, in particular on both the content and the process of developing forecast bulletins for decision-making.
High resolution (1 km) satellite rainfall estimation from SM2RAIN applied to Sentinel-1: Po River Basin as case study
Authors: Filippucci Paolo , Brocca Luca , Quast Raphael , Ciabatta Luca , Saltalippi Carla , Wagner Wolfgang , Tarpanelli Angelica
Published: November 2021

Abstract. Satellite sensors to infer rainfall measurements have become widely available in the last years, but their spatial resolution usually exceed 10 kilometres, due to technological limitation. This poses an important constraint on their use for application such as water resource management, index insurance evaluation or hydrological models, which require more and more detailed information. In this work, the algorithm SM2RAIN (Soil Moisture to Rain) for rainfall estimation is applied to a high resolution soil moisture product derived from Sentinel-1, named S1-RT1, characterized by 1 km spatial resolution (500 m spacing), and to the 25 km ASCAT soil moisture (12.5 km spacing), resampled to the same grid of S1-RT1, to obtain rainfall products with the same spatial and temporal resolution over the Po River basin. In order to overcome the need of calibration and to allow its global application, a parameterized version of SM2RAIN algorithm was adopted along with the standard one. The capabilities in estimating rainfall of each obtained product were then compared, to assess both the parameterized SM2RAIN performances and the added value of Sentinel-1 high spatial resolution. The results show that good estimates of rainfall are obtainable from Sentinel-1 when considering aggregation time steps greater than 1 day, since to the low temporal resolution of this sensor (from 1.5 to 4 days over Europe) prevents its application to infer daily rainfall. On average, the ASCAT derived rainfall product performs better than S1-RT1 one, even if the performances are equally good when 30 days accumulated rainfall is considered, being the mean Pearson’s correlation of the rainfall obtained from ASCAT and S1-RT1 equal to 0.74 and 0.73, respectively, using the parameterized SM2RAIN. Notwithstanding this, the products obtained from Sentinel-1 outperform those from ASCAT in specific areas, like in valleys inside mountain regions and most of the plains, confirming the added value of the high spatial resolution information in obtaining spatially detailed rainfall. Finally, the parameterized products performances are similar to those obtained with SM2RAIN calibration, confirming the reliability of the parameterized algorithm for rainfall estimation in this area and fostering the possibility to apply SM2RAIN worldwide even without the availability of a rainfall benchmark product.

Abstract. On 5 December 2018, a magnitude Mw 7.5 earthquake occurred southeast of Maré, an island of the Loyalty Islands archipelago, New Caledonia. This earthquake is located at the junction between the plunging Loyalty Ridge and the southern part of the Vanuatu Arc, in a tectonically complex and very active area regularly subjected to strong seismic crises and earthquakes higher than magnitude 7 and up to 8. Widely felt in New Caledonia, it was immediately followed by a tsunami warning, confirmed shortly after by a first wave arrival at the Loyalty Islands tide gauges (Maré and Lifou), and then along the east coast of Grande Terre of New Caledonia and in several islands of the Vanuatu Archipelago. Two solutions of the seafloor initial deformation are considered for tsunami generation modeling, one using a non-uniform finite-source model from USGS and the other being a uniform slip model built from the Global Centroid Moment Tensor (GCMT) solution, with the geological knowledge of the region and empirical laws establishing relationships between the moment magnitude and the fault plane geometry. Both tsunami generation and propagation are simulated using the Semi-implicit Cross-scale Hydroscience Integrated System Model (SCHISM), an open-source modeling code solving the shallow-water equations on an unstructured grid allowing refinement in many critical areas. The results of numerical simulations are compared to tide gauge records, field observations and testimonials from 2018. Careful inspection of wave amplitude and wave energy maps for the two simulated scenarios shows clearly that the heterogeneous deformation model is inappropriate, while it raises the importance of the fault plane geometry and azimuth for tsunami amplitude and directivity. The arrival times, wave amplitude and polarities obtained with the uniform slip model are globally coherent, especially in far-field locations (Hienghène, Poindimié and Port Vila). Due to interactions between the tsunami waves and the numerous bathymetric structures like the Loyalty and Norfolk ridges in the neighborhood of the source, the tsunami propagating toward the south of Grande Terre and the Isle of Pines is captured by these structures acting like waveguides, allowing it to propagate to the north-northwest, especially in the Loyalty Islands and along the east coast of Grande Terre. A similar observation results from the propagation in the Vanuatu islands, from Aneityum to Efate.

Abstract. Nowadays, special attention is paid to hydroelectric production
because it is an efficient, reliable, and renewable source of energy,
especially in developing countries like Cameroon, where hydropower potential
is the main source of electricity production. It also represents a useful
tool to reduce the atmospheric greenhouse gas concentrations caused by human
activities. However, it is the most sensitive industry to global warming,
mainly because climate change will directly affect the quality, quantity of
water resources (streamflow and runoff), which are the important drivers of
hydropower potential. This study examined the response of hydropower
potential to climate change on the Lagdo dam located in the Benue River
Basin, Northern Cameroon. Hydropower potential was computed based on
streamflow simulated using HBV-Light hydrological model with dynamically
downscaled temperature and precipitation from the regional climate model
REMO. These data were obtained using the boundary conditions of two general
circulation models (GCMs): the Europe-wide Consortium Earth System Model
(EC-Earth) and the Max Planck Institute-Earth System Model (MPI-ESM) under
three Representative Concentrations Pathways (RCP2.6, RCP4.5 and RCP8.5).
The results suggest that, the combination of decreased precipitation and
streamflow, increased PET will negatively impact the hydropower potential in
the Lagdo dam under climate change scenarios, models and future periods.
Studying recent hydroclimatic variability in Madagascar despite deficient measurement networks: use of CHIRPS and GRACE data at the scale of the Mahajunga province

Abstract. Given the lack of in situ hydroclimatic measurements and networks in Madagascar, the GRACE (2003–2016) spatial gravimetry data, combined with other satellite data such as CHIRPS rainfall estimates or fire monitoring using GFED products, make it possible to establish an interannual assessment of certain climatic and environmental covariations at the
northwest scale of the country. The results show a negative trend in
continental rainfall and water content, especially after 2007, but also a
time lag in the linear variations and trends of the Water Equivalent Height
as well as the number of detected fires (variable indirectly measuring the
pressure of deforestation by slash and burn agriculture).

Introduction: Globally 17.9 million people die each year from CVDs (Cardio Vascular Diseases) and 85% of all CVD deaths are due to heart attacks and strokes. According to the World Health Organization (WHO), 15 million people worldwide suffer from stroke every year and after ischemic heart disease, stroke is the second most leading cause of death. Objective: To study alcohol consumption as a risk factor in patients with acute strokes. Method: Case control study was conducted among 148 newly diagnosed cases of CT scan / MRI-confirmed stroke and 148 non-stroke controls attending the tertiary hospital of central Gujarat. Sample size calculation was done, assuming the power ratio of the number of controls same as numbers of cases i.e.,1:1, specifying values for two-sided confidence level=95% (error=5%), power of study=80%, odd ratio=2.15, percent of cases with exposure=82% and percent of controls with exposure=68%. Patients who are willing to participate in the study were included. The data were analyzed using the EPI INFO TM 7.0.8.0 software. Results: Out of the total 148 cases, 100 (67.56 per cent) were male and 48 (32.43 per cent) were female. The odds of getting stroke among alcoholic was two times more as compared to non-alcoholic patients. Heavy alcohol drinkers have a significant association. Conclusion: According to the study results male married patients who drank heavily had a higher risk of stroke than light/moderate alcoholics.

Esta pesquisa constitui parte da Tese de Doutorado em Educação, intitulada “Concepções de Professores sobre a Resolução de Problemas, vinculada institucionalmente ao Programa de Pós-Graduação em Educação (PPGED) pela Universidade Federal de Uberlândia (UFU). O estudo em questão buscou delinear o referencial histórico e teórico sobre a Resolução de Problemas (RP) enquanto uma metodologia, trazendo as principais teorias e também propor a RP a partir da perspectiva davydoviana. A abordagem metodológica foi a pesquisa qualitativa, com os desdobramentos da pesquisa teórica. Após a apresentação das principais teorias da RP, utilizamos a teoria de Davydov, que propõe um processo de ensino-aprendizagem-desenvolvimento dos conteúdos matemáticos pautado na atividade de estudo que marca a formação do pensamento teórico do estudante. A RP, na perspectiva de Davydov, é abordada na atividade de estudo do aluno, que, a partir das situações de dificuldade propostas pelo professor, se envolve com o resolver problemas no desenvolvimento das tarefas. A proposta de Davydov volta-se para a apropriação dos conteúdos matemáticos e o desenvolvimento da RP é fundamentado em aspectos científicos validados para o desenvolvimento do sujeito. A perspectiva de Davydov diverge das outras teorias da RP, por apresentar a preocupação com a apropriação dos conceitos e a formação do pensamento teórico. Elucidamos que a RP no âmbito desta pesquisa, antes de qualquer ação, prioriza a trajetória que é percorrida antes e durante a resolução do problema, visto que essa linha recorre aos conteúdos e aos fundamentos científicos, o que realmente importa para a formação dos estudantes.

Gluten sensitive enteropathy-celiac disease is an immune-mediated disorder caused by permanent sensitivity to gluten in genetically susceptible individuals. Epidemiologic studies of last years suggest that it is common and may occur in 0,5-1% of the general population. The bowel inﬂammatory and immunologic response results in atrophy and damage in the small bowel and secondary malabsorbtion. The mode of presentation can be quite variable. Celiac disease is generally deﬁned as chronic diarrea and failure to thrive in infants and toddlers, diarrhea is still the most common symptom, but disease may occure in different age groups and with exstraintestinal, sometimes monosymptomic clinic. Clinical forms of celiac disease are: classic, atypical, silent, latent and potential. Deﬁnitive diagnose of Celiac disease requires serrologic screening, small intestinal biopsy and effectiveness of elimination diet. Anti-tissue transglutaminase antybody test (TTG IgA and TTG IgG) is highly sensitive, speciﬁc and less expensive, thus is recommended for general practice. None of serologic tests are 100% reliable. Deﬁnitive diagnosis requires characteristic histologic changes in intestine mucus. Tissue for investigation may be taken from duodenum during gastro endoscopy. Diagnosing only by results of gluten-free diet is not correct. The only treatment for celiac disease is lifelong exclusion of gluten. Early diagnosis and strict dietary restrictions appear to be the only possibility of prevention risk for failure to thrive, delay of sexual maturity, autoimmune disorders, adenocarcinoma of gastrointestinal tract and lymphoma.
