Du devoir du chrétien à l’impératif du citoyen : les œuvres dans l’homilétique du Désert (1741-1791)
Authors: Borello Céline
Published: July 2019

Parce qu’ils sont une des rares prises de parole publique de la communauté huguenote durant la clandestinité du XVIIIe siècle, les sermons sont une source importante de l’étude du Désert protestant. Ils sont ici utilisés afin de percevoir les différents aspects de l’homilétique concernant les œuvres. Pour une cohérence documentaire, le choix des sermons s’est arrêté sur ceux de la première dynastie pastorale du XVIIIe siècle, celle des Rabaut : Paul (1718-1794), le père, ainsi que deux de ses fils, Jean-Paul (1743-1793) et Jacques-Antoine (1744-1820). De ce corpus de trois cents textes, il ressort tout d’abord une présence polymorphe des œuvres qui se lit dans les discours de chaire, de manière directe ou indirecte : à l’occasion de certains sermons et à partir de péricopes choisies, les pasteurs exhortent les fidèles aux « bonnes œuvres » et plus particulièrement à l’aumône à la fin du culte ou bien dans le cadre de collectes dans la semaine qui le suit. Un deuxième point abordé est la signification qui est donnée aux œuvres : certes, le salut par la foi est rappelé, les œuvres étant le symbole de la foi agissante mais, à plusieurs reprises, ces dernières sont présentées comme essentielles pour le salut. Enfin, il convient de souligner que ces discours s’inscrivent dans une réflexion qui n’est pas seulement religieuse mais aussi sociale : la bénéficence prêchée par les pasteurs Rabaut est un devoir du chrétien mais aussi une responsabilité du sujet et du citoyen.
L’aide aux pauvres dans l’Église réformée de Calais au XVIIe siècle
Authors: Joblin Alain
Published: July 2019

L’étude des communautés protestantes du Nord de la France sous l’Ancien Régime se heurte à la rareté des sources. Aussi, il est intéressant de présenter et d’analyser les quelques vestiges qui nous sont parvenus. C’est le cas du « registre des pauvres » tenus par les diacres de l’Église de Calais d’avril 1661 à juillet 1681. Ce registre est actuellement conservé à la Bibliothèque de la Société huguenote de Londres sous le titre : « The Poor Relief Account Book of Guines ». La source est précieuse car, au-delà des informations sur la vie quotidienne des huguenots calaisiens qu’elle livre, le chercheur peut découvrir une politique d’assistance aux pauvres ambitieuse et variée. L’Église venait ainsi en aide aux nécessiteux victimes de nombreuses crises frumentaires, aux orphelins, aux veuves et aux étrangers de passage dans la région qu’ils soient protestants ou non. Il faut remarquer la place laissée dans cette aide à l’école et à l’apprentissage, la finalité protestante de cette politique des « œuvres » étant de privilégier le travail à l’aumône. Des comptes précisément tenus révèlent l’origine de l’argent rendant possible cette politique : il s’agissait, pour l’essentiel de « cueillettes » réalisées à l’occasion du culte dominical. L’objectif est donc de présenter une politique de « bonnes œuvres » organisée et vécue au quotidien.
L’Asile protestant d’Orthez : des femmes à l’œuvre (1852-1905)
Authors: Lanusse-Cazalé Hélène
Published: July 2019

Aux lendemains de la reconnaissance officielle du protestantisme, les œuvres charitables protestantes se développent fortement en France sous l’effet du Réveil. L’Asile protestant d’Orthez, fondé en 1852, recueille de jeunes orphelines ou filles « exposées à de funestes influences » ainsi que des vieillards et des malades. Aux côtés des pasteurs et des conseillers presbytéraux, les femmes, et plus particulièrement les diaconesses, prennent part à la gestion quotidienne de l’établissement. Modèles de piété, celles-ci participent à la diffusion quotidienne d’une morale chrétienne. Leur professionnalisation est également un facteur de l’émancipation progressive des femmes.
A Data Privacy Governance Model
Authors: Stoll Margareth
Published: July 2019

The importance of data privacy, information availability and integrity are increasingly recognized. The new EU general data protection regulation 679/2016 obligates stringent legal requirements with high sanctions for noncompliance. Most organizations worldwide are affected directly or indirectly. It requires overall a risk and evidence-based data privacy management as part of corporate governance. More than 1.6 million organizations worldwide are implementing a standard-based management system, such as ISO 9001 or others. To implement the new data protection regulation in an effective, efficient and sustainable way, the author provides design-oriented guidelines on how to integrate the legal requirements into standard based management systems. The holistic data privacy governance model integrates different information security governance frameworks with standard based management systems in order to comply the regulation. In that way data privacy is part of all strategic, tactical and operational business processes, promotes corporate governance, legal compliance and living data protection.
Comparison of the Structure of AlCrSiN Coating Produced by Planar and Rotating Arc Technology
Authors: Galeja Justyna , Lukaszkowicz Krzysztof
Published: July 2019

The aim of this work was an attempt to verify two concepts of cathode modules, and the qualification of structure analysis of nitride coatings with the addition of silicon. The analysis covered one of the most commonly used in industrial conditions AlCrSiN coatings manufactured by the planar ARC and rotating (LARC®) technology, which have recently gained more and more recognition in the production of coatings by physical vapour deposition (PVD) technique. Their microstructure was examined using transmission electron microscope (TEM), scanning electron microscopy (SEM), and atomic force microscopy (AFM). Their mechanical and tribological properties were compared in terms of their application in the field of surface engineering. Tribological tests were performed in sliding friction conditions using the ball-on-disc method, where a ceramic Al2O3 ball was used as the counterpart. Presented research results allow to determine the relationship between the structure, wear resistance, and the specific module responsible for the number, type and position of cathodes used in the constitution of the tested coatings. This study complements and contributes to the knowledge on the direct influence of the chemical composition of the coating and the method of its production on the quality and structure of the coated element for wear-resistant coatings produced by PVD in the arc evaporation method (AE).

Published: July 2019

The aim of this work is to present the influences of composition of the material and manufacturing technology conditions of the organic photovoltaics devices (OPv) with the organic and hybrid bulk heterojunction on the active layers properties and cells performance. The layers were produced by using small molecular compounds: the metal-phthalocyanine (MePc) and perylene derivatives (PTCDA) and the titanium dioxide (TiO2) nanoparticles. Two kinds of metal phthalocyanines (NiPc, TiOPc) were used as donor material and pperylenetetracarboxylic dianhydride (PTCDA) as an acceptor. The used manufacturing technique allowed to employ thin layers of materials in a fast deposition process. Bulk heterojunction was created by simultaneously applying the MePc:PTCDA materials during the evaporation of the components mixture.The research was based on the estimate of composition of bulk heterojunction, the examination of the surface morphology of the used layers and optical properties studies of the heterojunction and its implementation to photovoltaic architecture. The produced photovoltaic cells parameters were determined on the basis of current - voltage characteristics.The researches of structure of obtained layers were conducted by using scanning electron microscope (SEM) and transmission electron microscopy (TEM). The quantitative determination of surface topography by determining RMS and Ra coefficients were performed by atomic force microscopy (AFM). In order to determine the optical properties of the films the UV-Visible spectroscope have been utilized. Current - voltage characteristics were employed to determine the basic photovoltaic parameters using a dedicated device.The paper describes the influence of the individual components sharing the bulk heterojunction on its structure, optical properties and morphology of surface. In addition it allows for linking active layers properties with the parameters of the photovoltaic cells. The obtained results suggest the possibility of developing the utilized materials and technology in the further works on photovoltaic structures.

Published: July 2019

A 62-year-old man with a history of systemic sclerosis was admitted with diffuse alveolar hemorrhage and acute kidney injury without clinical data suggestive of glomerulonephritis. Laboratory tests showed anemia, leukocytosis with neutrophilia, thrombocytopenia, elevated serum creatinine and metabolic acidosis. Antinuclear antibodies were positive at a titer of 1/640 (speckled, 1/160; nucleolar, 1/320) while rheumatoid factor, anti Scl-70, anti-centromere, anti-neutrophil cytoplasmic antibody and anti-glomerular basement membrane antibodies were negative and serum complement levels were within normal range. During the following days, the patient developed multiple organ failure and, eventually, died. Lupus anticoagulant was revealed positive after the patient’s death, suggesting a catastrophic antiphospholipid syndrome. Clinical data and autopsy were consistent with this diagnosis.

Published: July 2019

Anti-tumor necrosis factor drugs are used routinely according to treatment guidelines for several chronic rheumatologic problems. However, a rare and usually unpredictable adverse drug reaction namely peripheral nervous system demyelination is being increasingly recognized. Biosimilars are gaining momentum especially in countries like India. Hence, we report a case of Guillain-Barré syndrome secondary to an etanercept biosimilar, probably the first case reported so far.

Authors: Younis A.A. , Hamed R.A. , Abdulkareem I.H.
Published: July 2019

Angioleiomyomas are benign tumors originating in the vascular smooth muscles. The tumor typically presents as a painful, solitary, small subcutaneous nodule. Herein, we have described a case report of chronic leg pain due to angioleiomyoma. We outline the clinical, radiological and histopathological features of this rare diagnosis for a painful nodule of extremity. Although rare, angioleiomyoma should be included in the differential diagnosis of chronic leg pain.
Conventional and magnetic resonance hysterosalpingography in assessing tubal patency—A comparative study
Authors: Jagannathan Devimeenal , Hithaya Fouzal
Published: July 2019

Context: Tubal factors, one of the leading causes of female infertility, have been conventionally evaluated by hysterosalpingography (HSG). The role of magnetic resonance imaging (MRI) in assessing female infertility is gaining importance because of its inherent efficiency in detecting structural abnormalities. Magnetic resonance hysterosalpingography (MR HSG) is less invasive and avoids exposure of ovaries to ionizing radiation. Its utility is extrapolated to visualize fallopian tubes. Aims: To assess the diagnostic accuracies of dynamic MR HSG and conventional HSG (cHSG) in identifying tubal patency in women with infertility using diagnostic laparoscopy (DL) as gold standard. Materials and Methods: A prospective study of 40 patients was conducted over a period of 6 months. The patients were subjected to MR HSG followed by cHSG during the preovulatory period. If tubes were blocked, the patients were subjected to DL in the next menstrual cycle. If the tubes were patent and there was failure of conception, they were subjected to DL in the interval of 3 months. Results: Twenty-four patients had bilateral tubal spill which was confirmed using cHSG and DL. One patient had discordant MR HSG and cHSG results and six patients had discordant MR HSG and DL results. No statistical difference was observed between MR HSG and cHSG. Conclusion: Pelvic MRI is an inevitable tool in infertility evaluation. MR HSG can be used in addition as it avoids exposure of the reproductive organs to radiation and has the same efficacy as cHSG.
Basic interventional procedures: Practice essentials
Authors: Mukund Amar , Bhardwaj Krishna , Mohan Chander
Published: July 2019

There has been an increasing demand in image-guided minimally invasive procedures and these have become an integral part of present-day clinical practice. Basic interventional radiology (IR) procedures have greatly reduced the need for invasive procedures for sampling as well as treating conditions like abscess and fluid collections. Owing to their minimally invasive nature, most of these procedures may be performed on the outpatient patients as daycare procedures. Some of these procedures in critically ill patients may be lifesaving. Basic interventional radiology (IR) procedures consist of image-guided fine-needle aspiration cytology and biopsy, tru-cut (core) biopsy, needle aspiration/drainage and percutaneous catheter drainage. This review aims to provide practice requisites for basic IR procedures.

Published: July 2019

OBJECTIVES: Tuberculosis (TB) is a global public health problem that causes morbidity and mortality in millions of people per year. The purpose of this study was to examine the relationship of potential risk factors with TB mortality in Iran.METHODS: This cross-sectional study was performed on 9,151 patients with TB from March 2017 to March 2018 in Iran. Data were gathered from all 429 counties of Iran by the Ministry of Health and Medical Education and Statistical Center of Iran. In this study, a generalized estimating equation-based zero-inflated negative binomial model was used to determine the effect of related factors on TB mortality at the community level. For data analysis, R version 3.4.2 was used with the relevant packages.RESULTS: The risk of mortality from TB was found to increase with the unemployment rate (βˆ=0.02), illiteracy (βˆ=0.04), household density per residential unit (βˆ=1.29), distance between the center of the county and the provincial capital (βˆ=0.03), and urbanization (βˆ=0.81). The following other risk factors for TB mortality were identified: diabetes (βˆ=0.02), human immunodeficiency virus infection (βˆ=0.04), infection with TB in the most recent 2 years (βˆ=0.07), injection drug use (βˆ=0.07), long-term corticosteroid use (βˆ=0.09), malignant diseases (βˆ=0.09), chronic kidney disease (βˆ=0.32), gastrectomy (βˆ=0.50), chronic malnutrition (βˆ=0.38), and a body mass index more than 10% under the ideal weight (βˆ=0.01). However, silicosis had no effect.CONCLUSIONS: The results of this study provide useful information on risk factors for mortality from TB.
Evaluating the Renoprotective Activity of 4-Methylthiobutyl Isothiocyanate against 7,12-Dimethylbenz(α) anthracene generated Radical Stress in Male Wistar Rats
Authors: Kukreja Sahiba , Arora Rohit , Mannan Rahul , Bhushan Sakshi , Arora Saroj
Published: July 2019

Aim

An increasing environmental pollution has elevated the number of deleterious pollutants present in the atmosphere. Among these, polyaromatic hydrocarbons, such as 7,12-dimethylbenz(α)anthracene (DMBA) have posed serious threat to the health of both animals and plants. Most of these compounds are genotoxic in nature and an elevated exposure of these carcinogens increases the risk of initiation and promotion of cancer. The low efficacy, specific target sites, and large number of side effects of the available drugs have encouraged researchers to look for an alternate drug with high biological potency. The best alternate for this is the use of medicinal plants and especially their phytochemicals, such as glucosinolate hydrolytic products. A large number of glucosinolate hydrolytic products are available in different plant species, but sulforaphane has emerged as the most potent among them. This important compound is interconverted to 4-methylthiobutyl isothiocyanate (4-MTBITC) or erucin in the body of an organism. In contrast to sulforaphane, not much work has been done on the biological properties of 4-MTBITC. The current study, therefore, focuses on evaluating the renoprotective activity of 4-MTBITC on DMBA induced nephrotoxicity in male Wistar rats.

Materials and methods

The bioprotective efficacy of erucin was evaluated in male Wistar rats treated with DMBA using the levels of serum creatinine, urea, sodium, and potassium.

Results

The treatment with erucin significantly ameliorated the DMBA induced stress in male Wistar rats.

Conclusion

Erucin or 4-MTBITC has the potential to impart protection to male Wistar rats against genotoxic carcinogen (DMBA) induced stress.

Narratividade jornalística e a inferência das redes sociais na produção de conteúdo do site de notícias HuffPost Brasil
Authors: Horn Aline Tainá Amaral
Published: July 2019

Este artigo visa investigar o tratamento do conteúdo jornalístico na edição brasileira do pure player HuffPost, sobre um caso de assédio sexual sofrido por uma jornalista, e verificar como as redes sociais serviram de matéria-prima para a produção das notícias na cobertura desse acontecimento. O referencial teórico está embasado no conceito de gatewatching (BRUNS, 2011) e no fenômeno de contra-agendamento (SILVA, 2008), a partir da compreensão de que o uso das redes sociais nas redações alterou as práticas jornalísticas (BE DIAF, 2013), e que o público passa a influenciar a produção jornalística (ESTIENNE, 2007). A análise qualitativa das notícias – coletadas entre junho e novembro de 2016 – se ancora nas perspectivas teórico-metodológicas de análise pragmática da narrativa jornalística (MOTTA, 2008). Conclui-se que a cobertura jornalística enfatiza a desaprovação da opinião pública sobre o caso, e que as campanhas das redes sociais encadeiam ritmo e prolongam a narrativa jornalística.

Published: July 2019

Background and aims – An increased interest in the diatom flora from subaerial habitats in the Republic of North Macedonia has revealed the presence of a large number of interesting and often unknown, species. During a recent biodiversity survey, seven Muelleria species were recorded, several of which could not be identified based on the available literature.

Methods – Using both Light Microscopy and Scanning Electron Microscopy techniques, the morphology of several Muelleria species has been analysed. The morphology of all taxa is described, illustrated and compared with other possible similar Muelleria taxa, known worldwide.

Key results – Four already documented Muelleria species, M. gibbula, M. islandica, M. terrestris and M. undulata (= Navicula gibbula f. undulata) were identified, while two distinct species are described as new. These new species belong to the M. gibbula complex, and can be differentiated by valve size, stria density, shape of the proximal raphe ends and the shape of external areola foramina. The identity of one taxon remains uncertain due to a low number of observed specimens in the samples. As their ultrastructure is almost entirely unknown, they are briefly discussed.

Conclusions – The diversity of Muelleria in Europe and the North Hemisphere is most likely underestimated and some of the previous records of M. gibbula belong to other species. Observations of diatoms from “extreme” habitats such as intermittent ponds, wet mosses and soils can reveal the existence of interesting and new species.
Taxonomy and diversity of a little-known diatom genus Simonsenia (Bacillariaceae) in the marine littoral: novel taxa from the Yellow Sea and the Gulf of Mexico

Published: July 2019

Background and aims – The diatom genus Simonsenia has been considered for some time a minor taxon, limited in its distribution to fresh and slightly brackish waters. Recently, knowledge of its diversity and geographic distribution has been enhanced with new species described from brackish-marine waters of the southern Iberian Peninsula and from inland freshwaters of South China, and here we report novel Simonsenia from fully marine waters.

Methods – New isolates of Simonsenia species were obtained from marine waters, the littoral zone of the Korean Yellow Sea coast and the Gulf of Mexico in Corpus Christi (Texas), and documented in LM, SEM and with DNA sequence data (plastid-encoded rbcL and psbC). Phylogenetic trees of raphid diatoms were constructed to assess the relationships of the new species and of the genus as a whole.

Key results and conclusions – Two novel species of Simonsenia (S. eileencoxiae and S. paucistriata) are described and a further putative taxon is characterized morphologically. The molecular phylogeny of the new Simonsenia species and previously sequenced species supports both the monophyly of the genus and its place within the Bacillariaceae. The Simonsenia clade clusters with clades composed of Cylindrotheca, Denticula and some Nitzschia spp. (including N. amphibia, N. frustulum, N. inconspicua). Hence Simonsenia is firmly positioned within the Bacillariaceae by molecular phylogenies, confirming its position within this group based on the possession of a canal raphe and its ultrastructure, and rejecting its classification within the Surirellaceae. Morphological data from the new Simonsenia species is typical for the genus, with a “simonsenioid” canal raphe type supported over the valve face with fenestral braces, alar canals connecting the canal raphe with the cell lumen, and the presence of fenestrae between the alar canals externally. Our results indicate unequivocally that the biogeography and the biodiversity of Simonsenia remain highly underestimated.

Published: July 2019

Background and aims – The present study aims to describe a new species of pennate blue diatom from the genus Haslea, H. nusantara sp. nov., collected from Semak Daun Island, the Seribu Archipelago, in Indonesian marine waters.

Methods – Assessment for species identification was conducted using light microscopy, Scanning Electron Microscopy and molecular techniques. The morphological characteristics of H. nusantara have been described, illustrated and compared to other morphologically similar blue Haslea taxa, distributed worldwide. Additionally, molecular characterization was achieved by sequencing plastidial and mitochondrial genomes.

Key results – This new species, named Haslea nusantara, cannot be discriminated by its morphology (stria density) but it is characterized by its gene sequences (rbcL chloroplast gene and cox1 mitochondrial gene). Moreover, it differentiates from other blue Haslea species by the presence of a thin central bar, which has been previously reported in non-blue species like H. pseudostrearia. The complete mitochondrion (36,288 basepairs, bp) and plastid (120,448 bp) genomes of H. nusantara were sequenced and the gene arrangements were compared with other diatom genomes. Phylogeny analyses established using rbcL indicated that H. nusantara is included in the blue Haslea cluster and close to a blue Haslea sp. found in Canary Islands (H. silbo sp. ined.).

Conclusions – All investigations carried out in this study show that H. nusantara is a new blue-pigmented species, which belongs to the blue Haslea clade, with an exceptional geographic distribution in the Southern Hemisphere.
GlobSim (v1.0): Deriving meteorological time series for point locations from multiple global reanalyses
Authors: Cao Bin , Quan Xiaojing , Brown Nicholas , Stewart-Jones Emilie , Gruber Stephan
Published: July 2019

Abstract. Simulations of land-surface processes and phenomena often require driving time series of meteorological variables. Corresponding observations, however, are unavailable in most locations, even more so, when considering the duration, continuity and data quality required. Atmospheric reanalyses provide global coverage of relevant meteorological variables, but their use is largely restricted to grid-based studies. This is because technical challenges limit the ease with which reanalysis data can be applied to models at the site scale. We present the software toolkit GlobSim, which automates the downloading, interpolation and scaling of different reanalyses – currently ERA-5, ERA-Interim, JRA-55 and MERRA-2 – to produce meteorological time series for user-defined point locations. The resulting data have consistent structure and units to efficiently support ensemble simulation. The utility of GlobSim is demonstrated using an application in permafrost research. We perform ensemble simulations of ground-surface temperature for ten terrain types in a remote tundra area in northern Canada and compare the results with observations. Simulation results reproduced seasonal cycles and variation between terrain types well, demonstrating that GlobSim can support efficient land-surface simulations. Ensemble means often yielded better accuracy than individual simulation and ensemble ranges additionally provide indications of uncertainty arising from uncertain input. By improving the usability of reanalyses for research requiring time-series of climate variables for point locations, GlobSim can enable a wide range of simulation studies and model evaluations that previously were impeded by technical hurdles in obtaining suitable data.
Soil lacquer peel do-it-yourself: simply capturing beauty
Authors: Stoof Cathelijne R. , Candel Jasper H. J. , van der Wal Laszlo A. G. M. , Peek Gert
Published: July 2019

Abstract. Visualization can greatly
benefit understanding of concepts and processes, which in soil science and
geology can be done using real-life snapshots of soils and sediments in
lacquer peels and glue peels. While it may seem complicated, anyone can make
such a soil peel for use in classrooms, public places, homes, and offices for
teaching, outreach, decoration, and awareness. Technological development has
considerably simplified the making of soil peels, but this methodological
innovation has not been described in the literature. Here, we report on a
thoroughly tested and simple method for taking peels of sandy soils using
readily available tools and materials. Our method follows the main previously
published steps of preparing a soil face, impregnating the soil face with a
fixation agent in the field, extracting the resulting peel, and mounting it
on a wooden panel. Yet instead of using lacquers and thinning agents, we use
strong though flexible contact adhesive (glue), which has the major advantage
that it no longer requires use and mixing of toxic chemicals in the field or
reinforcement of the peel to prevent breaking. Moreover, the preservation
potential is much higher than with the old method. This new twist to old
methods makes creation of soil peels safer, simpler, and more successful, and
thereby a true DIY (do-it-yourself) activity. The resulting increased accessibility of
making soil and sediment peels can benefit research, teaching, and science
communication and can thereby bring the value and beauty of the ground below
our feet to students, schools, policy makers, and the general public.
Estimating Early-Winter Antarctic Sea Ice Thickness From Deformed Ice Morphology
Authors: Mei M. Jeffrey , Maksym Ted , Singh Hanumant
Published: July 2019

Abstract. Satellites have documented variability in sea ice areal extent for decades, but there are significant challenges in obtaining analogous measurements for sea ice thickness data in the Antarctic, primarily due to difficulties in estimating snow cover on sea ice. Sea ice thickness can be estimated from surface elevation measurements, such as those from airborne/satellite LiDAR, by assuming some snow depth distribution or empirically fitting with limited data from drilled transects from various field studies. Current estimates for large-scale Antarctic sea ice thickness have errors as high as ~ 50 %, and simple statistical models of small-scale mean thickness have similarly high errors. Averaging measurements over hundreds of meters can improve the model fits to existing data, though these results do not necessarily generalize to other floes. At present, we do not have algorithms that accurately estimate sea ice thickness at high resolutions. We use a convolutional neural network with laser altimetry profiles of sea ice surfaces at 0.2 m resolution to show that it is possible to estimate sea ice thickness at 20 m resolution with better accuracy and generalization than current methods (mean relative errors ~ 15 %). Moreover, the neural network does not require specifying snow depth/density, which increases its potential applications to other LiDAR datasets. The learned features appear to correspond to basic morphological features, and these features appear to be common to other floes with the same climatology. This suggests that there is a relationship between the surface morphology and the ice thickness. The model has a mean relative error of 20 % when applied to a new floe from the region and season, which is much lower than the mean relative error for a linear fit (errors up to 47 %). This method may be extended to lower-resolution, larger-footprint data such as such as IceBridge, and suggests a possible avenue to reduce errors in satellite estimates of Antarctic sea ice thickness from ICESat-2 over current methods, especially at smaller scale.

Published: July 2019

O projeto “Horta Universitária: plantando ciência e reduzindo desigualdades” teve como objetivo criar um ambiente cada vez mais sustentável dentro da universidade, a partir da elaboração de uma horta comunitária, com a participação de estudantes de graduação dos diversos cursos ofertados nos Campi da Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM), em Diamantina, visando promover a redução da retenção e evasão. Cerca de 87,5 % dos integrantes da equipe do projeto melhoraram seu Coeficiente de Rendimento Acadêmico (CRA). Portanto, podemos inferir que a abertura de uma oportunidade para que estudantes dos diversos cursos de graduação da UFVJM venham a integrar algum tipo de projeto em âmbito universitário, mesmo como voluntário, além de cumprir com o dever constitucional da universidade referente a indissociabilidade do ensino, pesquisa e extensão, torna-se uma atividade motivadora e que contribui positivamente para a manutenção ou melhoria do rendimento acadêmico. Por sua vez, a melhoria no rendimento acadêmico, elimina um possível fator que levaria a evasão desse aluno do curso ou da instituição de ensino superior.
Memória Do Programa “Trilhas Potiguares” (1996-1999): 23 Anos Depois
Authors: Sousa Andréia Da Silva Quintanilha
Published: July 2019

Este artigo revisita a atividade de extensão denominada “Trilhas Potiguares” desenvolvida na Universidade Federal do Rio Grande do Norte (UFRN). Essa atividade foi objeto da pesquisa intitulada “Memória do Programa Trilhas Potiguares de 1996-1999”. A pesquisa de natureza qualitativa visava, dentre outros objetivos, preservar a memória dessa atividade de extensão e foi realizada em nível de mestrado no Programa de Pós-graduação em Educação da UFRN entre os anos 1998 a 2000. Hoje, o Programa Trilhas Potiguares está na sua vigésima terceira edição e é considerado o “maior Programa de Extensão” da UFRN conforme Fraga e Villa (2017). O Relatório das Trilhas Potiguares do ano de 2018 divulga que o Programa envolve 243 alunos, 43 cursos, 11 Centros, desenvolve 743 ações e 29.886 pessoas foram atendidas pelo programa (UFRN, 2019b). Passadas mais de duas décadas da realização da pesquisa, é possível afirmar que as atividades de extensão do Trilhas preservam os aspectos positivos identificados naquele estudo realizado há vinte anos: a sua capacidade de articular ensino e extensão. Porém, acompanha a tendência mundial que convoca as universidades a assumirem o protagonismo no processo de desenvolvimento da sociedade, nos campos científicos, social, econômico, ambiental e cultural nos marcos da racionalidade neoliberal.

Authors: Kirima Lucy Karimi
Published: July 2019

The purpose of the study was to establish socio-cultural factors affecting gender mainstreaming in the ministry of education. The study used descriptive survey research design. The target population consisted of the county and sub-county gender coordinators and the heads of public secondary schools. Embu and Tharaka-Nithi was selected purposively because of low transition rate from primary to secondary schools. A total of 211 respondents were sampled through purposive and random sampling techniques. A questionnaire and an interview schedule were used to collect primary data. Descriptive statistics were used to summarize the properties of the mass data that were collected from the respondents. Factor analysis method was used to determine the factors that were used in the study namely; strength of strategies, gender mainstreaming strategies, gender policy in education, gender disparities in education and understanding of the policy which were used in logistic regression analysis. Logit regression was used to determine the effect of the factors on gender mainstreaming. Among the five factors, only one factor (gender disparities in education) affected gender mainstreaming negatively. All other predictor variables: strength of strategies; gender mainstreaming strategies; gender policy in education and understanding of gender policy in education affected gender mainstreaming positively. From the findings, it is evident that Gender policy in education is not being implemented effectively in the public secondary schools and there are several factors affecting gender mainstreaming in the education sector which includes; inadequate commitment from top-down to the institution, gender concept was not well understood, inadequate training and awareness for teachers, gender imbalance and inadequate training for Board of Governors and Parents Teachers Association, inadequate resources and socio-cultural factors. The study concluded that the school heads, teachers and management were ill-prepared for the policy implementation, there is inadequate support, training and awareness. Also, there is poor system of monitoring and evaluation. More so, policies and strategies outlined for secondary schools are appropriate and satisfactory but requires balancing between boys and girls.
La inserción a la docencia: una política pendiente en el marco de un sistema de formación permanente en Honduras
Authors: Díaz Dora Suyapa
Published: July 2019

El presente artículo tiene como propósito analizar los resultados de la investigación realizada el año 2017, a docentes del sistema educativo hondureño en los niveles de Básica y Media en zona urbana y rural, con el interés de plantear un aporte científico que contribuya a fortalecer un programa de formación docente novel como sistema a la inserción. El estudio hace énfasis en cuatro aspectos: la inserción del docente novel, programa integral, formación permanente y la identidad del docente. La información empírica fue obtenida por docentes activos en los departamentos de Francisco Morazán, Cortes, Atlántida, Choluteca, Santa Bárbara, ubicados en la zona central, sur, occidente de Honduras. En el trabajo de campo participaron asistentes técnicos de las Direcciones Departamentales correspondientes. Al realizar el estudio se detectó que el sistema educativo hondureño está pendiente de implementar un programa de inserción a docente novel, intermedio y experimentado; siendo una realidad educativa para ser discutido en la agenda de las autoridades educativas y tomar la decisión. Asimismo, de ser posible, construir una política educativa en forma acertada, participativa y con actores clave. Esta realidad de no contar con programas de inserción refleja debilidad del ejercicio de ser docente y, consecuentemente, en las competencias dentro del ejercicio de la docencia; también, debilidad en el concepto sobre la identidad y los procedimientos de contratación docente. Todo esto se estaría reflejando en los indicadores de la calidad educativa. En este sentido, el estudio utilizó como instrumento metodológico técnicas cualitativas como las de grupos colaborativos y entrevistas, las cuales contienen una serie de datos sobre la caracterización de programas de inserción, la identidad del ejercicio docente, los procedimientos de contratación; así como la caracterización de los modelos de capacitación implementados. Además, se utilizó el método de teoría fundamentada de referentes teóricos y documentos oficiales.

Published: July 2019

Increasing demand for wood resulted in competition between different branches of wood-based production. High intensity production, like the production of wood-based panels, is forced to look for other lignocellulosic resources. Bark is a possible source for wood-based panel industry, especially for particleboards. Bark chips were crushed into bark dust, which were used for the production of single-layer particleboards. The share of bark dust was 0 %, 0.5 %, 1 %, 5 % and 10 %. The boards were tested on thickness swelling (immersion in water, exposure to humid conditions) and internal bond. The highest internal bond was determined in the particleboard with 1 % bark share. Thickness swelling of boards with added bark was higher compared to boards without bark. The highest swelling was observed in boards with 10 % bark dust (immersion in water) or 5 % (humid conditions). Bark based boards absorbed less water.

The most ordinary way to use wind energy for building heating needs is to convert mechanical wind energy into electrical energy and to use electrical energy for heating. Though there are ways to convert mechanical wind energy into thermal energy without transitional energy conversion – hydraulic systems can be implemented for this purpose. Wind rotor gives rotational motion to the pump of hydraulic system and it creates fluid circulation in the hydraulic system. A part of liquid mechanical energy due to hydraulic resistance of the system converts into the thermal energy when the liquid circulates in the close hydraulic loop and it heats up the liquid that can be used for heating purposes. Different hydraulic valves can be integrated in the hydraulic system and they can work as the load-regulating component of the system. The purpose of the study was to adjust the hydraulic load to the optimal value in order to generate a maximum amount of thermal energy. During the study, the work of a wind rotor was simulated by an electric motor, rotated at different frequencies (without feedback). The hydraulic system consisted of a gear pump, an adjustable load regulation valve, pipes, oil tank, sensors for measuring motor shaft rotational speed, oil temperature and pressure. The experiments were carried out at different electromotor speeds: 12.5, 17.5 and 22.5 Hz, and for different oil temperatures in the range of 20 to 50 °C. The relationship between the opening degree of the valve and the amount of generated thermal energy was determined. The study showed that wind energy usage can cover a significant part of the building's thermal energy needs at the same time reducing pollution and the usage of the fossil fuel for heating purposes.

This paper focuses on cross-laminated timber (CLT) and how it is affected by the dynamic properties of moisture during installation in the cold climate of Estonia. The moisture safety principles are designed using a case study of comparable activities with 4D principles and on-site water content monitoring. On-site water content monitoring was done on the CLT elements that were installed and a parallel polygon specimen. Polygon testing was arranged with reduced size CLT elements subject to different conditions, with some exposed to the climate, some protected from precipitation, and some covered with film.

The moisture content (MC) of the uncovered horizontal CLT element that was exposed to the climate reached over 25% after higher precipitation and the MC after prolonged direct exposure can reach up to 40% in a week, giving a clear signal of high risk areas for moisture safety. Installing a partly weather protected CLT element without a preliminary roof is a high-risk arrangement, but is essentially possible in a cold climate. Moisture safety pre-planning and a lean strategy must be applied with timber construction.
St. Catherine of Siena
Authors: Ragazzi Grazia Mangano ,   Society of Catholic Social Scientists
Published: July 2019

In this article, the author shows how Catherine of Siena, a mystic who lived in Italy for thirty-three years in the second part of the fourteenth century, known for ecstasies and revelations, put discretion (and prudence, its synonym), the leading virtue in the moral life, at the core of her spirituality, thus becoming a real lover of the truth and a teacher of true freedom. The article contains bibliographical references for the reader’s further study of the writings (Dialogue, Letters, and Prayers) linked to this formidable figure, who was canonized in 1461 and proclaimed a Doctor of the Church in 1970. Catherine’s teaching, firmly anchored in what the Church and her great Doctors have always taught, remains to this day a rich treasure for spiritual growth.
Parent and Administrator Perceptions of Hybrid Homeschools
Authors: Wearne Eric ,   Society of Catholic Social Scientists
Published: July 2019

This article reports the results of a series of interviews with “hybrid homeschool” parents and administrators. “Hybrid homeschools” are entities which generally operate as formal schools two to three days per week, with teachers, enrolled students, and brick and mortar buildings. The balance of the week, students learn as homeschoolers. Previous research into hybrid homeschools has consisted mainly of electronic surveys asking families why they choose this schooling model, what they value in education for their children, and demographic questions. The purpose of this study is to build on these surveys by conducting longer-form qualitative interviews with hybrid homeschool parents, teachers, and administrators. This study reports the results of a series of semi-structured interviews conducted with seven participants from four schools in two states over the course of the 2017–2018 school year. The results of these interviews support some of the broad suggestions made in previous electronic survey results, while also adding to what parents value in these schools, and why they choose them.
