Aggressiva talgoxar Parus major: utsvultna fåglar eller tillhörande en annan population?
Authors: Ryttman Hans
Published: April 2019

During autumn 2016, bird ringing stations in east Sweden observed Great Tits Parus major with extremely aggressive behaviour. They attacked smaller birds such as Goldcrests Regulus regulus, killed them and ate the brain or the content of the belly. I examine with data from Ottenby Bird Observatory two explanations: the birds were exhausted after migration and very hungry or they were birds from an eastern population where aggressive behaviour has been suggested to be more common. Fat index and body mass did not indicate low energy stores and the weather was stable with wind from the east so the ﬁrst explanation was not supported. Unfortunately, wing length cannot be used to differentiate between Swedish and more eastern populations so also the second explanation could not be supported. However, Great Tits from eastern parts of north Europe moult their alula earlier than birds from Sweden. The next time aggressive Great Tits are observed, bird ringers should check the moulting stage of the alula in order to determine their origin.
Green Warbler Phylloscopus nitidus ringed at Blåvand: molecular confirmation of a Danish first and European eighth vagrant record
Authors: Stervander Martin , Knudsen Henrik , Bruun Kristensen Henrik
Published: April 2019

On 27 May 2015, a Green Warbler Phylloscopus nitidus was caught and ringed at Blåvand Bird Observatory, the westernmost point in Denmark. The species is challenging to identify on morphological basis alone, and the bird’s identity was conﬁrmed with phylogenetic analyses of mitochondrial DNA sequences. This constitutes the ﬁrst record of Green Warbler in Denmark, the third record in Fennoscandia – following records on Öland, Sweden, on 29 May 2003, and Åland, Finland, on 20 May 2012 – and the eighth vagrant record in Europe outside the species’ very restricted peripheral breeding range.
Phloem sap in fire-damaged Scots pine provides instant foraging opportunities for Three-toed Woodpeckers Picoides tridactylus
Authors: Pakkala Timo , Kouki Jari , Piha Markus , Tiainen Juha
Published: April 2019

Three-toed Woodpeckers Picoides tridactylus are known to use phloem sap of conifer trees as a food resource mostly in springtime. A local pair instantly began to forage sap of Scots pine Pinus sylvestris trees that were damaged in a prescribed forest burning; before the ﬁre they had used phloem sap elsewhere in their territory. During three weeks after the ﬁre, the pair intensively used sap of Scots pines which were exposed to ﬁre. The woodpeckers were probably attracted by nutrients induced by damage reaction of the burned pines. Rapid sap use of newly burned trees has not been described before, and it indicates behavioural plasticity how this woodpecker species can use resources in disturbance driven, dynamic forest environments.
Häckningsframgång hos ormvråk Buteo buteo och kattuggla Strix aluco i Varbergs kommun 1984–2016
Authors: Kanje Bo , Kanje Sonja
Published: April 2019

In 1984–2016 we studied the habitat choice, nest placement and breeding success of Common Buzzard Buteo buteo and Tawny Owl Strix aluco in the municipality of Varberg in southwest Sweden (57°10'N, 12°10'E). The analyses are based on 1,512 successful breeding attempts of Common Buzzard, and 1,387 of Tawny Owl. The average number of young per successful breeding was 1.74 and 2.86, respectively. The variation between years was highly correlated between the two species, suggesting a common food source. In both species the between-year variation in clutch size was particularly large in beech forest territories, most likely caused by the effect of beech mast years on local rodent populations. The breeding density of Common Buzzard was particularly high in 1990–1995, coinciding with large areas of farmland set-aside. In the Common Buzzard, the yearly average number of young per clutch declined significantly with yearly average hatching date.
A Great Tit Parus major without yellow pigment in its plumage
Authors: Svensson Sören , Kadin Germund
Published: April 2019

A Great Tit Parus major without any yellow pigment in the plumage was ringed in southern Swedish Lapland in 2006. Such pale birds are known to appear with a low frequency throughout the species’ range. Superficially they look like the eastern (sub)species Parus (major) minor. The focal bird was a yearling with a wing length well above that of minor so there is no reason to suspect eastern origin. The yellow pigment, a carotenoid, is obtained through food, particularly green larvae. Such larvae were available in reasonably high numbers in 2006. The focal bird was an exception as no other pale Great Tit has been recorded during more than fifty years of fieldwork in the area. Yellow at the flange of the gape indicates that the bird had not completely lost its capacity to take up pig-ments, only the plumage was affected.
Sewage sedimentation ponds – a lost bird paradise: a nostalgic return visit and case study
Authors: Svensson Sören
Published: April 2019

Sewage ponds with exposed sludge are known to be excellent feeding sites for waders during migration. They still exist in parts of the world but are disappearing in pace with introduction of modern methods which do not involve open exposure of the sludge. Here I report a five-year study from a Swedish plant with open sludge ponds in the 1950s when many similar ones were still active. I counted the waders with frequent visits from 18 April through 2 November, 1952–1956. Ninety-three percent of the dates had a visit in at least one of the years giving an almost complete combined coverage of migration. Nineteen species were recorded at least once. The total average annual number of bird-days was 2868 (5% in spring). Most abundant were the Ruff Calidris pugnax with 35% and Wood Sandpiper Tringa glareola with 32% of all bird days. Temminck’s Stint Calidris temminckii showed the highest spring proportion of bird-days, 30%.
Planning the supply of gas LPG to the filling station network
in the concept of stocks controlled by the carrier
Authors: Kaleta Jacek
Published: April 2019

In this paper, supply system of LPG to fuel station is presented as a specific example of vendor managed inventory replenishment concept. A single hauler of LPG is considered, which operates within the network of domestic depots and performs deliveries to hundreds of final customers being responsible for full accessibility for all supported LPG stations. The carrier is responsible for the entire LPG supply planning process (volume as well as scheduling of deliveries), information process, completed deliveries and any problems arising during execution. In the article the LPG supply process and the planning system which has been developed are presented with a brief presentation of an interactive computer system (DSS implementation) developed and implemented in the reporting enterprise. The work ends with an indication of the benefits of using a system approach to planning and determination of the directions for further research.

Deformations of the surface and trackbed beside the bridge objects - tests and diagnostics
Authors: Sołkowski Juliusz , Jamka Maciej
Published: April 2019

In the paper the results of research into dynamic rail deflections and rail accelerations under passing trains are presented. The research was carried out on five railway bridges within the precinct of Krakow Railway Management. The objects varied as to their construction (ballasted, ballastless structures) and tonnage borne. The measurements were carried out in the period of 18 months. As a result, special algorithms for predicting the geometrical deformations and the changes in the dynamic stiffness of the railway structure (track, subgrade, bridge) were worked out. These algorithms were implemented in the diagnostic data base DIAGTOR. Some examples of the algorithms and calculations are presented in the paper.
Railway Traffic Regional in Silesia - history or the future
Authors: Trzoński Karol
Published: April 2019

Silesian Voivodeship is the most populated area in Poland, having a well-functioning road network and a dense rail network, which unfortunately is not sufficiently used due to low capacity due to poor technical condition (at medium speeds not exceeding 30 km/h for passenger traffic and 20 km/h for freight traffic). On the railway network in Silesia there is mixed traffic, ie. Commodity-passenger. Often freight traffic has priority over passenger traffic and a number of railway lines is greater % of occupancy. The article presents the historical regional railway, which was to be dedicated to only passenger traffics, as a movement dedicated on Silesia for such carriage. Unfortunately, for economic reasons and it seems that the political, this project has not been implemented, even though part of the design was made at 100% and part of the infrastructure at 30%.

Applying the COM-B Model to Assess the Usability of Smartphone-Connected Listening Devices in Adults with Hearing Loss
Authors: Maidment David W. , Ali Yasmin H. K. , Ferguson Melanie A.
Published: April 2019

Background:Unlike conventional hearing aids, smartphone-connected listening devices may require limited or no input from a trained audiologist in terms of device programming and adjustment. However, there is a lack of peer-reviewed evidence assessing the real-world perspectives
of people living with hearing loss toward such technological innovations.Purpose:This study assessed the everyday experiences of adults living with hearing loss toward a range of smartphone-connected listening devices using the Capability, Opportunity, Motivation, Behaviour (COM-B)
model as a theoretical framework.Research Design:A qualitative study where participants trialed one of the following smartphone-connected listening devices for two weeks in their everyday lives: made-for-smartphone hearing aid, personal sound amplification product, and smartphone “hearing
aid” app with wired earphones or wireless hearable. Individual semistructured interviews were conducted.Study Sample:Twenty adults (13 male and 7 female; mean age = 62.25 years, SD = 11.59) with mild-to-moderate hearing loss (mean better ear pure-tone average = 30.49 dB HL, SD
= 17.51) were recruited using a convenience sampling strategy. All participants owned conventional hearing aids.Data Analysis:The data were analyzed using an established deductive thematic analysis procedure within the context of the COM-B model. The model stipulates that for individuals
to engage in a particular behavior (B), they must have sufficient capability (C), opportunity (O), and motivation (M).Results:Capability: One of the key advantages facilitating use and adherence of smartphone-connected listening devices was the ability for participants to make
fine-tune adjustments in any listening situation. Opportunity: Participants commented that these devices could address issues surrounding stigma as smartphones are ubiquitous in everyday life. Motivation: Participants consistently reported that the ability to make adjustments
via a smartphone provided them with a greater sense of autonomy and empowerment. As a result, they felt more in control of their hearing loss.Conclusions:This study lays the foundation for further high-quality research to explore whether smartphone-connected technologies have the potential
to yield optimum benefits for people living with hearing loss.
Possible Evidence for Cosmic-Ray Acceleration in the Type Ia SNR RCW 86: Spatial Correlation between TeV Gamma-Rays and Interstellar Atomic Protons

Published: April 2019

We present a detailed morphological study of TeV gamma-rays, synchrotron radiation, and interstellar gas in the young Type Ia supernova remnant (SNR) RCW 86. We find that the interstellar atomic gas shows good spatial correlation with the gamma-rays, indicating that the TeV gamma-rays from RCW 86 are likely predominantly of hadronic origin. In contrast, the spatial correlation between the interstellar molecular cloud and the TeV gamma-rays is poor in the southeastern shell of the SNR. We argue that this poor correlation can be attributed to the low-energy cosmic rays (∼1 TeV) not penetrating into the dense molecular cloud due to an enhancement of the turbulent magnetic field around the dense cloud of ∼10–100 μG. We also find that the southwestern shell, which is bright in both synchrotron X-ray and radio continuum radiation, shows a significant gamma-ray excess compared with the interstellar proton column density, suggesting that leptonic gamma-rays via inverse Compton scattering possibly contribute alongside the hadronic gamma-rays. The total cosmic-ray energies of the young TeV gamma-ray SNRs—RX J1713.7−3946, Vela Jr, HESS J1731−347, and RCW 86—are roughly similar, which indicates that cosmic rays can be accelerated in both the core-collapse and Type Ia supernovae. The total energy of cosmic rays derived using the gas density, ∼1048–1049 erg, gives a safe lower limit due mainly to the low filling factor of interstellar gas within the shell.
Bird diversity along riverine areas in the Bhagirathi Valley, Uttarakhand, India
Authors: Sinha Ankita , Hariharan Hima , Adhikari Bhupendra , Krishnamurthy Ramesh
Published: April 2019

Natural riverine areas mark ecotonal habitats harbouring a characteristically diverse faunal assemblage, especially birds that also use these habitats as pathways crucial for their movement. Increasingly, riverine systems are subjected to large-scale habitat alterations due to climatic fluctuations and anthropogenic changes. Therefore, it is important to understand broad-scale community patterns for conservation planning and prioritisation for these ecotone habitats. The Bhagirathi river is one of the major headwaters of the river Ganges; despite its rich and diverse fauna, little is known about the bird species that inhabit this montane region. This study presents an extensive list of 281 bird species from 59 families, their seasonal distribution and habitat associations as recorded from field surveys along the riverine areas between April 2013 and May 2018. The present communication simultaneously discusses a few noteworthy sightings for the region and provides a baseline for future research on the distribution of birds in the Western Himalaya.

Transitional Experiences: From Clinical Nurse to Nurse Faculty
Authors: Hoffman Danielle M.E.
Published: April 2019

Background:

A limited pool of nurse faculty has affected enrollment of nursing students and the ability to produce the nursing workforce needed for the evolving health care system. The experiences clinical nurses face as they transition to the faculty role may contribute to the faculty shortage.

Method:

A qualitative descriptive study was conducted to explore the lived experiences of clinical nurses as they entered the nurse faculty role. A purposive sample was recruited from two higher learning institutions in the midwestern United States. Data analysis was performed using Colaizzi's method.

Results:

Four themes emerged: Perpetual Novice, Faculty as a Resource, Teaching Ambiguity, and Student as My Patient. The prominent theme surrounded the idea that the faculty were in a state of constant change as a perpetual novice.

Conclusion:

Implications exist for academic nursing program administration to invest in developing nurse faculty skill level and ease the transition to the role.

Inspiring Empathy and Policy Action in Undergraduate Students: Monopoly as a Strategy
Authors: Adams Sara B.
Published: April 2019

Background:

Baccalaureate-prepared nurses report low levels of confidence and fail to view policy-level advocacy as an essential role of the nurse. Innovations in baccalaureate curricula intended to bolster empathy with regard to vulnerable groups and to increase awareness of the advocacy role are essential.

Method:

Cross-sectional descriptive methods were used to explore the impact of a modified version of the game Monopoly—created to simulate a social environment of socioeconomic disadvantage—on nursing student perspectives of advocacy.

Results:

Data were analyzed from oral debriefing and written reflections following the exercise. A content analysis was performed that revealed themes of Awareness, Emotional Response, Empathy, and Advocacy.

Conclusion:

This exercise challenged student perspectives and ultimately enhanced awareness, empathy, and intent to advocate for socioeconomically disadvantaged groups.

Teaching Prioritization: “Who, What, & Why?”
Authors: Jessee Mary Ann
Published: April 2019

Background:

New graduate nurses must be equipped to prioritize the needs of multiple complex patients and intervene on problems causing the highest risk of adverse outcomes. Targeted and theoretically supported strategies to teach prioritization without significant change to clinical education structure are needed.

Method:

A structured, scaffolded prioritization exercise using individual and peer-learning strategies engages prelicensure nursing students in purposeful practice prioritizing care needs for individuals and groups of patients. The exercise uses students' assigned clinical patient data, during existing clinical conference sessions, across a three-semester clinical course sequence with baccalaureate-level prelicensure nursing students.

Results:

Students appreciate the peer learning and coaching provided by instructors during this activity. Instructors identify that students more readily recognize potential and actual risks and prioritize nursing actions in conferences and clinical sessions.

Conclusion:

Simple and theoretically based teaching strategies offer a pathway for teaching students to recognize salient features of complex patient situations, prioritize actions, and provide safe patient care.

Accelerating Improvement of a Doctor of Nursing Practice Project Proposal Course Using Quality Improvement Methods
Authors: Durham Marianne L. , Yingling Charles , Hershberger Patricia E.
Published: April 2019

Background:

Transition from traditional research-based to Doctor of Nursing Practice (DNP) projects led students and faculty in our program to express confusion and anxiety about proposal requirements and project planning. This demanded an improvement approach to engage students and faculty.

Method:

Plan-Do-Study-Act cycles were used to accelerate improvement in the first DNP project course. Strategies targeted both students and faculty mentors and included tools and resources to assist with course and project navigation. Voice of the customer feedback and lessons learned were used to plan for improvement in the next cycle.

Results:

After four PDSA cycles, student evaluation of course quality was favorable and scholarly writing and feasibility improved. Student comments about course anxiety and confusion decreased and faculty mentors' confidence improved.

Conclusion:

A quality improvement strategy is a successful approach for continued course improvements and can role model quality improvement approaches expected in DNP project work.

Characterization of lignocellulosic composition and residual lipids in empty fruit bunches from palm oil processing
Authors: Volpi M. P.C. , Bastos R. G. , Badan A. P.R. , Santana M. H.A. , Santos V. S.
Published: April 2019

Empty fruit bunches (EFBs) are an agro-industrial residue discarded in the environment when the fresh palm fruits are removed for oil extraction. EFBs are abundant in palm-oil-producing countries and cause environmental problems. Besides their content in lignocellulosic, EFBs also contain amounts of residual lipids from the separation process. Because the palm fruit has two main types of oil from the pulp (palm oil) or the seeds (kernal oil), the residual EFBs lipids may have different compositions. Thus, this work aimed at characterizing the lignocellulosic content and the residual lipids in two EFBs from different palm oil producers. The EFBs were classified as Type 1 and Type 2 according to their source. The results showed that Type 1 EFBs had higher lignocellulosic and fatty acid compositions, similar to palm and kernel oils, while Type 2 EFBs had lower lignocellulosic content and fatty acid composition, similar to palm oil.

Published: April 2019

The authors' research activities connected information and communication technologies affecting teaching methods in higher education. A total of 201 respondents studying Programming 2 participated in this research. Two hypotheses were created, as well as a pre-test (ensuring that the initial condition of equality among the group members was met) and a post-test (measuring the shift of knowledge among the respondents of the same group). An analysis based on the t-test showed the presence of a statistically significant difference among the male respondents with regard to the test results. H1 hypothesis was accepted. No statistically significant difference was detected among the female respondents, so the H2 hypothesis was rejected. Our results showed that major difference have been found only in male population, which is interesting since female respondents tend to use LMS systems more often and since male respondents are more frequently in computer games activities.
NEUTRALIZAÇÃO DE CARBONO POR MEIO DE INVENTÁRIO DAS EMISSÕES DE GASES DE EFEITO ESTUFA A PARTIR DO PLANEJAMENTO INSTITUCIONAL DA UFU
Authors: Gonzaga Eunir Augusto Reis , Wendling Beno
Published: April 2019

As ações antrópicas após a Revolução Industrial passaram a considerar o Meio Ambiente como espaço fornecedor de recursos naturais ao modelo de produção capitalista globalizado. Com isso suprimiu-se a vegetação nativa de diversos biomas, substituindo o espaço outrora composto por fauna e flora nativa por cidades, indústrias, agriculturas, pastagens, gerando poluição atmosférica, o que impactou diretamente no atual contexto de mudanças climáticas. Nesse sentido, observou-se a ausência de registros públicos de inventários, contendo emissões de gases de efeito estufa da Universidade Federal de Uberlândia (UFU). O propósito do trabalho foi identificar no planejamento institucional indicadores aquisição de energia elétrica e de energia térmica, utilizando a ferramenta Global Reporting Initiative (GRI) intersetorial. Escolheu-se a metodologia GHG Protocol por ser um padrão internacionalmente aceito. Os principais resultados obtidos foram as emissões em toneladas de gás carbônico equivalente para o ano 2014, propondo neutralização por meio do plantio de mudas nativas do Bioma Cerrado. O inventário não apenas pode viabilizar a implantação de medidas para mitigação e compensação, como também pode contribuir com a otimização dos gastos públicos, por meio de um planejamento macro que esteja alinhado com as atividades de ensino, pesquisa e extensão, mas também que contribua com os eixos temáticos da Agenda Ambiental da Administração Pública (A3P), proposta pelo Ministério do Meio Ambiente.

Published: April 2019

Os desafios que se apresentam frente à inclusão de alunos com NEE, no ensino de Geografia, têm sido alvo de discussões, não apenas dentro das instituições de ensino, mas em diversos segmentos da sociedade. Assim, este artigo procurou refletir acerca do processo de inclusão de alunos com Necessidades Educacionais Especiais no ensino de Geografia. O objetivo desta produção consistiu em avaliar a contribuição do uso do Mapa Conceitual enquanto instrumento de avaliação na preparação na formação inicial do professor de Geografia voltada para a Educação Inclusiva. A partir da interpretação e da análise dos resultados obtidos, verificou-se que, com as atividades desenvolvidas em grupo e com o professor sendo parte do processo de mediação pedagógica em todas as etapas de construção dos instrumentos de análise, houve promoção da preparação na formação inicial do professor de Geografia voltada para a Educação Inclusiva. Por fim, concluiu-se a pesquisa observando-se a necessidade de que professores de Geografia compreendam as consideráveis influências de suas atividades pedagógicas no crescimento intelectual e pessoal de seus alunos, sabendo que a preparação do professor é um momento necessário, pois propicia a atualização de um corpo teórico conjugado com os mais modernos conhecimentos científicos e possibilita o reconhecimento cada vez mais acentuado da função social da escola.
MAPEAMENTO DAS ÁREAS DE PRESERVAÇÃO PERMANENTE NO PERÍMETRO URBANO DO MUNICÍPIO DE CANOINHAS – ESTADO DE SANTA CATARINA
Authors: Tabalipa Felipe , Voos Vieira Celso
Published: April 2019

A manutenção de ambientes entendidos como de preservação ambiental é relevante para salvaguardar os recursos hídricos, estabilidade geológica e a biodiversidade do território municipal, conforme previsto na legislação ambiental federal. O objetivo deste trabalho foi a delimitação e a análise das Áreas de Preservação Permanente (APP) considerando os parâmetros determinados pela legislação vigente (Lei Federal nº 12.651/12) no perímetro urbano do município de Canoinhas com a utilização de Sistema de Informação Geográfica (SIG). Para o cumprimento do objetivo proposto foi utilizada a base cartográfica digital do município de Canoinhas, da Secretaria de Estado do Desenvolvimento Sustentável (SDS) e da EPAGRI/IBGE, que permitiram manipular dados geográficos referentes a altimetria e recursos hídricos. Em função das inconsistências das bases digitais disponibilizadas no que diz respeito à hidrografia, foi necessário a geração de um modelo hidrológico para reconstituir a rede de drenagem do perímetro urbano. Entre as categorias passíveis de aplicação de APP de acordo com a legislação ambiental vigente, citam-se as áreas associadas aos cursos d’água, nascentes e declividade, não existindo outros enquadramentos. No presente estudo foi identificado uma área total de 7,3 km2 de restrições ambientais que representa 22,5% do perímetro urbano do município de Canoinhas. As principais intervenções antrópicas ocorreram nos cursos d’água, principalmente com a retificação e a canalização dos canais. Todavia, nas áreas que apresentam amplas planícies de inundação dos principais cursos d’água observou-se a manutenção da mata ciliar em estágio inicial e médio de regeneração.

Published: April 2019

Este trabalho insere-se no “Zoneamento Ambiental das Sub-bacias Hidrográficas dos Afluentes Mineiros do Médio Rio Grande”. O objetivo geral foi estabelecer uma classificação do terreno quanto ao potencial à produção rural e, com isto, fornecer aos gestores públicos e à comunidade regional uma ferramenta útil no planejamento agropecuário e no desenvolvimento sustentável da bacia hidrográfica. Para a efetivação desta abordagem buscou-se realizar uma análise conjunta de atributos levantados na área, dentre os quais: clima, relevo, substrato rochoso e solo, além dos aspectos legais relacionados ao uso e ocupação do solo. Todos os processamentos foram realizados em um sistema de informações geográficas (SIG). O produto final foi a Carta de Potencial à Produção Rural e a classificação de 1607 unidades ambientais quanto ao potencial à produção rural. Dentre as unidades que demandam mais cuidados com relação à preservação estão aquelas situadas no setor norte, que abrange a unidade de conservação denominada Parque Nacional da Serra da Canastra e sua zona de amortecimento. No setor sudoeste concentram-se áreas com alto potencial à produção agropecuária, principalmente aquelas onde predominam substrato de rochas efusivas básicas. Neste mesmo setor, entretanto, ocorrem áreas que concentram processos erosivos pronunciados e que demandam práticas conservacionistas no uso do solo.

O PAPEL DAS LOCALIDADES NA URBANIZAÇÃO ESTENDIDA DA AMAZÔNIA CONTEMPORÂNEA: TIPOLOGIA DAS COMUNIDADES DO SUDOESTE DO PARÁ ENQUANTO NÓS DE UMA REDE URBANA LOCAL
Authors: Amaral Silvana , Dal'Asta Ana Paula
Published: April 2019

Este artigo destaca a contribuição de unidades territoriais de escala local na estruturação da rede urbana na Amazônia Brasileira. Apoiados no referencial teórico da urbanização estendida, composta por unidades espaciais de diferentes tipologias de ocupação, apresenta-se um estudo sobre as comunidades do sudoeste paraense, enquanto nós de uma rede urbana em escala local. Além da caracterização e hierarquia dos nós, buscou-se verificar a influência do contexto na classificação destes nós quanto ao fato de estarem incluídos ou não em unidades de conservação (UC); e quanto à localização ao longo de rios (ribeirinhas) ou estradas (terrestres). De 2009 a 2015, expedições de campo anuais caracterizaram 236 comunidades quanto à origem e organização da população, à presença de equipamento e infraestrutura urbana, ao acesso a serviços de saúde e educação, e às formas de uso da terra, sumarizadas em 28 variáveis. A avaliação estatística multivariada (teste T2 de Hotelling) indicou que comunidades inseridas em UC apresentam médias das variáveis significativamente diferentes das encontradas para as comunidades não incluídas em UC, evidenciando a importância da regulação do uso da terra para as condições das comunidades na região. A análise estatística de agrupamentos, baseada em inferência fuzzy, identificou cinco grupo de comunidades, ordenados das melhores (Fuzzy 1) para as piores condições (Fuzzy 5) identificadas pelas variáveis. Estes grupos foram descritos e avaliados quanto à sua evolução temporal, distribuição no espaço geográfico e variáveis condicionantes, e comparados a estudos anteriores. A maior frequência de comunidades terrestres no cluster Fuzzy 1, e das ribeirinhas nos clusters de condições pior (Fuzzy 5) a intermediária (Fuzzy 2) indicam que comunidades terrestres apresentaram-se melhores estruturadas que as ribeirinhas. Assim, ao retratar as comunidades como elementos de aspectos comuns e particulares, numa tipologia hierárquica dos seus atributos, espera-se contribuir com informações úteis para a definição de políticas de conservação e sustentabilidade regional.

Published: April 2019

The efficiency of bacterial biomass as an adsorbent for the removal of Chromium in a fixed column was the subject of this study. The effect of different parameters such as initial Cr (VI) concentrations (25, 50, and 100mg/L), flow rate (0.5, 0.75, and 1 mL/min), and bed depth (8, 16, and 24 cm) on Cr (VI) biosorption were investigated. The breakthrough data obtained for Cr (VI) removal was more adequately described by the Clark and Yan model with high correlation coefficients (R2 = 0,996). According to the results obtained, fixed bacterial biomass was estimated as possible biosorbent for removal of chromium (VI) from aqueous solutions in a dynamic process.

Published: April 2019

The aim of this research is to investigate and to evaluate the changes that occur on the surface of wood specimens, coated with three different coatings and exposed to artificial weathering. The three used coatings contain linseed oil and different types of pigments. Specimens of pine wood (Pinussylvestris L.) were painted with one or two layers of coatings to evaluate the discoloration and changes in lightness. For all the tested coatings, discoloration and loss of lightness were observed for all specimens regardless of the applied coatings. Different rates of color changes were observed for the tested coatings. The presence of pigments in the coatings formulation delays the discoloration of wood; as also the composition of pigments plays a significant role in the process.

The production of low-temperature clay lightweight aggregates is pursued eagerly as low energy and cost lightweight aggregate concrete (LAC) building blocks becomes more popular. Clay ceramic hollow spheres (CCHS) with waste glass (WG) additive was developed and studied as aggregate in cement composite. CCHS with diameter ranging in 6/8mm were produced by a sacrificial template technique with subsequent sintering under temperature of 900 °C and different WG content of 0, 5, 7 and 10 wt%. The effect of the sintering temperature and WG content on the physical properties and morphology of the CHS-cement composites were studied by means of optical microscopy and mechanical properties. Obtained composite materials were compared with commercially available lightweight fillers such as foamed glass granules and lightweight expanded clay aggregates (LECA). The results compressive strength of CCHS containing LAC is much higher from 4.8 to 7.1 MPa in comparison with the LECA-cement LAC - 3.5 MPa. Reduction of CCHS open porosity due to higher content of WG (10%) leads to lower absorption of cement paste, as result lower cement consumption, lower bulk density and compression strength. LAC with CCHS proved to be promising construction material due to low-temperature production process (i), widely available raw material (clay) and secondary material (glass cullet) use (ii), reduction of cement paste needed for material production (iii).

Few derivatives of 3-arylmethyl-4-hydroxycoumarin and 4-aryl-3,4-dihydrocoumarin as potential free radical scavengers were synthesized. The antiradical activity of these compounds was measured according to 1,1-diphenyl-2-picrylhidrazyl and galvinoxyl tests. It strongly depends on phenol-type substituent attached to the coumarin skeleton, nevertheless the chromen-2-one scaffold by itself plays an important role for the antiradical activity.

Published: April 2019

Today, artificial implants (AI) industry depends strongly on tribological constitution of the material (s) of the implant. Erosion, corrosion, tribocorrosion and biocorrosion are essential factors to determine both functionality and lifetime of the AIs. Histo-Biocompatibility is also an additional constraint, indispensable for implant manufacturing process. The prediction of durability, based on the computational and experimental study of constituents of AI material (s) are key factors to obtain objective data of any AI characteristics. This contribution deals with a computational comparative analysis of materials for hip implants using Archard’s model mainly. Selected hip implant material hardness are Co-Cr alloy and Titanium types. Method is carried out with specific material data, e.g., hardness or wear constants, nonlinear optimization and graphical subroutines. Results presented are both numerical and graphical. Particular interest is focused on application of the 3D Graphical Optimization method.

Reactive oxygen species (ROS) can damage lipids, nucleic acids, and proteins, thereby altering their functions. When a balance between production of ROS and antioxidative defense is disturbed, state of oxidative stress occurs. Oxidative stress leads to many diseases. There are few biomarkers that are used for better understanding how oxidative stress is involved in cancer pathophysiology. This review focuses on 8-hidroxy-2-deoxyguanosine (8-OHdG) and antioxidative enzymes as biomarkers for measurement of oxidative stress in different types of cancer. This review also deals with the product of lipid peroxidation, malondialdehyde (MDA), and across a variety of cancers. To address this aim, analysis of studies of breast, prostate, lung, colon, cervical, ovarian, brain, bladder, renal, thyroid cancer, and chronic lymphocytic leukemia has been conducted. In general, levels of antioxidative enzymes are mostly lower in cancer patients, while 8-OHdG and MDA are higher. Further research is needed, with focus on correlation levels of these biomarkers and advancement of the disease. Moreover, all studies explored the idea of those biomarkers as a useful tool in determining the levels of oxidative stress. Some of the studies proposed their potential in defining the stage of tumor progression.

Chikungunya (CHIK) has emerged as a major public health concern worldwide. Recently, atypical manifestations are drawing special attention because these might be associated with various complications. Information on atypical manifestations of CHIK is still limited. Here, we analyzed a dataset of 1,326 cases from our recent Dhaka outbreak study to explore the demographics and distributions of atypical manifestations. About 80% of cases reported at least one atypical symptom. Among all atypical symptoms, the most common and unique atypical symptom was joint pain before fever (90.2%), occurred predominantly in female respondents. Other common symptoms included red eye (68.2%), oral ulcer (37.7%), and dermatological manifestations (27.1%). More than two-thirds of patients reported multiple atypical symptoms. Atypical manifestations were not significantly different across age groups, except ocular complications. This study would be an important resource for clinicians and epidemiologists to understand the diversity of Chikungunya infection and, thus, help in better patient management.
Casas Vedoble

Published: April 2019

Este conjunto de 4 casas nace de una investigación sobre la variación tipológica a partir de un “prototipo”, la Casa Equis, situada en la misma bahía. Con la creciente densificación de construcciones en playa La Escondida, operamos como lo hace el tiempo en los pueblos de la costa peruana, declinando un prototipo, el rancho, según las circunstancias de uso, de situación específica y de los anhelos de sus moradores.

Si bien las casas no fueron diseñadas como un conjunto, prolongándose en un período de tres años, ellas forman un conjunto compacto y coherente por encontrarse en lotes vecinos y provenir todas de un mismo “prototipo”. Ellas forman parte de un único laboratorio de investigación proyectual sobre las condiciones de habitabilidad que ofrece el desierto peruano.

La disponibilidad del recurso hídrico es de vital importancia para la planificación hidrológica, este depende de múltiples causas como la variabilidad climática y la cobertura vegetal. La precipitación, temperatura y evapotranspiración han sufrido cambios en diferentes partes de España. Para la cuenca del río Júcar además de otras cuencas en España se ha producido un significativo cambio en el valor promedio de las aportaciones hidrológicas desde 1980. El presente estudio se centra en analizar cómo han afectado los cambios en las variables climáticas a las aportaciones hidrológicas y en qué grado explican las reducciones registradas en las mismas. Adicionalmente se considera la posibilidad de que otros factores como cambios en la cobertura vegetal también puedan haber influido en la reducción de escorrentía. Para modelar la hidrología de la cuenca del Júcar se utilizó el modelo lluviaescorrentía HBV. El modelo fue calibrado para periodo anterior a la fecha de cambio considerada (1950-1979) y se simuló y adaptó para los años posteriores a 1980 (1980-2007) ajustando parámetros que puedan ser explicados por cambios en las condiciones de la cuenca. La zona más susceptible es la cabecera del Júcar donde se genera la mayor cantidad del recurso hídrico y se presenta la mayor disminución en las aportaciones. En la cuenca media del Júcar se presenta una menor disminución en las aportaciones, sin embargo en la cuenca baja del Júcar se registra un incremento en las aportaciones. Los cambios en las variables hidrológicas (precipitación y temperatura) explican una parte de los cambios en las aportaciones. Otras causas posibles como los cambios en la cobertura vegetal pueden completar la explicación del cambio en las aportaciones. Para probarlo se ha recalibrado el modelo hidrológico alterando solo uno o dos parámetros relacionados con esta condición.
Mies en Canadá: una revisión de sus proyectos y obras en Toronto y Montreal
Authors: La Spina Vincenzina
Published: April 2019

The main goal of this paper is to show the work of the Modern Movement architect Mies van der Rohe in Canada. A total of 7 projects, 2 of them not implemented and an urban collaboration in the cities of Toronto and Montreal. Most of them are not relatively unknown projects with the exception of the Toronto-Dominion Centre and the Westmount Square in Montreal. These projects were carried out in the 1960s, in his last creative period, when he was over 70. Nevertheless, these projects are unique and iconic, the architect redeveloped and improved solutions and ideas already used in previous projects, and also addressed a different architectural use, the gas station. Mies’s Canadian work adapts his architecture typologies morphologically: high-rise building, pavilion building and the combination of both in complexes paying attention to urban configuration. Consequently, each project is analysed from a historical, typological and compositional perspective, paying attention to its particularities and linking these to other projects by the architect, mainly in the United States.
