A implantação do Parque Natural Municipal de Marapendi, no Rio de Janeiro
Authors: Poian Pedro Paulo Da
Published: May 2017

RESUMO O artigo procura identificar os principais entraves para a implantação efetiva do Parque Natural Municipal de Marapendi (PNM de Marapendi), no Rio de Janeiro, tal como previsto no Plano Diretor da Cidade do Rio de Janeiro. A metodologia empregada foi a realização de extensa pesquisa bibliográfica, complementada com levantamento de dados de campo e documentação fotográfica, além da participação do autor em ciclos de debates sobre o tema. Foram levantadas algumas ações que ampliariam a possibilidade de que aquela implantação ocorresse de fato, sendo, inclusive, defendida a ampliação do PNM de Marapendi mediante a anexação do vizinho Parque Natural Municipal da Barra da Tijuca (PNM da Barra da Tijuca). Na concepção do autor, o parque passaria a ser uma área de lazer extraordinária, sem que suas características de mata de restinga e fauna típicas fossem afetadas. Esse parque teria uma área quase três vezes maior que a do Aterro do Flamengo, circundando uma lagoa com um espelho d’água uma vez e meia maior que o da Lagoa Rodrigo de Freitas.

Published: May 2017

RESUMO Os perímetros irrigados de Gorutuba/Lagoa Grande e Jaíba localizam-se na porção mineira do Médio São Francisco, totalizando cerca de 31.493 ha. Essa região possui potencial de contaminar os recursos hídricos em decorrência da urbanização, do desmatamento e da utilização de fertilizantes e de agrotóxicos nas atividades agrícolas. O objetivo desta pesquisa foi investigar o impacto da irrigação na qualidade das águas superficiais da região, utilizando fontes de dados secundários de monitoramento. Foram selecionadas nove estações de monitoramento da qualidade da água superficial na região, que representavam diferentes usos e ocupação do solo. A análise de cluster e o teste não paramétrico de Kruskal-Wallis, seguido do teste de comparações múltiplas, foram utilizados para avaliar comparativamente as estações de amostragem, bem como identificar os parâmetros que apresentaram comportamentos diferenciados entre essas estações. Apesar de não ter sido possível observar um padrão de contaminação em função da localização das estações, detectou-se que as estações localizadas ao longo do Rio São Francisco não apresentaram diferenças significativas entre si, ainda que o uso e ocupação do solo fossem diferentes. A tendência temporal dos constituintes foi verificada através da aplicação do teste de hipótese de estacionariedade de Spearman, o qual detectou que a maioria dos dados analisados foram não estacionários, apresentando tendência de elevação ou redução ao longo do período analisado. Após a aplicação desses testes estatísticos, concluiu-se que, de maneira geral, a implantação de perímetros irrigados causou baixo impacto na qualidade das águas na região, no período estudado, considerando os parâmetros analisados neste trabalho.
A Inclusão de Crianças com Necessidades Educativas Especiais no Ensino Regular em Portugal: a Opinião de Educadores de Infância e de Professores do 1º Ciclo do Ensino Público e Privado
Authors: VIEIRA-RODRIGUES Margarida Maria de Moura , SANCHES-FERREIRA Maria Manuela Pires
Published: May 2017

RESUMO: este artigo particulariza dados de uma pesquisa e teve como objetivo descrever a opinião dos docentes acerca da inclusão de alunos com Necessidades Educativas Especiais e conhecer os fatores que justificam essas opiniões, após seis anos da implementação de um decreto Português que teve o objetivo de promover a igualdade de oportunidades, valorizar a educação e promover a melhoria da qualidade do ensino. Foram inquiridos 244 docentes de escolas públicas e privadas do Porto, através de um instrumento constituído por cinco vinhetas que descreviam diferentes funcionamentos de crianças. Os resultados indicaram que as crianças descritas com funcionamentos compatíveis com Perturbação de Espetro de Autismo e Paralisia Cerebral foram as menos aceitos, sendo as justificações aduzidas a falta de formação, a impossibilidade de despender o tempo de ensino necessário e a exigência dos outros alunos obterem bons resultados acadêmicos. A formação em Educação Especial apenas estava associada à maior aceitação de alunos com Paralisia Cerebral, e ser docente-educador versus professor do 1º ciclo influencia a aceitação de alunos com Perturbação de Espetro de Autismo, Paralisia Cerebral e Atraso Global de Desenvolvimento/Dificuldades de Aprendizagem. Os docentes do ensino privado evidenciaram maior aceitação dos alunos descritos do que os do público.

RESUMO: o objetivo do presente estudo foi avaliar as habilidades sociais de alunos com deficiência intelectual, antes e após um programa de Educação Física, sob a perspectiva dos professores. Desenvolveu-se sob abordagem quantitativa, com delineamento quase-experimental. A amostra foi composta por sete crianças com idade entre sete e 14 anos (M=10; DP=2.61) e três professores com idade entre 24 e 45 anos (M=37.67; DP=12.34). Os participantes foram avaliados pelos respectivos professores, por meio do instrumento Sistema de Avaliação das Habilidades Sociais (SSRS-BR), aplicado antes e após um programa de intervenção em Educação Física. O programa foi composto por 24 sessões, com duração de 40 minutos cada, durante dois meses. As informações obtidas por meio do SSRS-BR foram analisadas quantitativamente pelo Método JT. Dos sete participantes, cinco obtiveram mudança positiva confiável nas habilidades sociais após o programa de Educação Física. A categoria social mais influenciada foi a responsabilidade, sendo que houve uma mudança positiva nas habilidades sociais globais. Conclui-se que após o programa de Educação Física as crianças com deficiência intelectual obtiveram um aumento no escore global das habilidades sociais.
Entre Chicago e Salvador: Donald Pierson e o estudo das relações raciais
Authors: Maio Marcos Chor , Lopes Thiago Da Costa
Published: May 2017

Resumo Este artigo analisa, de uma perspectiva histórica transnacional, a pesquisa sobre relações raciais desenvolvida pelo sociólogo norte-americano Donald Pierson na cidade de Salvador entre 1935 e 1937, que resultou na sua tese de doutorado defendida na Universidade de Chicago sob orientação de Robert Park. Partimos da hipótese de que a forma como o sociólogo apresenta e analisa o vasto material coletado na Bahia, assim como as proposições de caráter mais geral contidas em seu livro, somente adquirem significado quando se explicita, além dos diálogos com os cientistas sociais brasileiros, seu enquadramento conceitual subjacente, que remonta à agenda de pesquisas capitaneada por Robert Park.
Between the Cold War and the Global South: Argentina and Third World Solidarity in the Falklands/Malvinas Crisis
Authors: Krepp Stella Paresa
Published: May 2017

Abstract This article looks at Argentine attempts to mobilize the Third World support by framing the Falklands/Malvinas War as a North-South conflict. Despite fundamental ideological divisions, the Organization of American States (OAS) and the Non-Aligned Movement offered support to Argentina, while the NATO powers - the European Economic Community (EEC) and the United States − backed Great Britain. The Falklands/Malvinas was thus a conflict where nationalist agendas linked up with global narratives of decolonization and the Global South.
Historiografias periféricas em perspectiva global ou transnacional: eurocentrismo em questão
Authors: Santos Pedro Afonso Cristovão dos , Nicodemo Thiago Lima , Pereira Mateus Henrique de Faria
Published: May 2017

Resumo O presente artigo discute questões teóricas envolvidas na reflexão sobre a história da historiografia a partir das perspectivas global/transnacional. Examinando estudos de historiografia em contextos distintos, pensados em particular a partir dos estudos subalternos e dos estudos pós-coloniais, o artigo pondera o problema do uso de uma concepção de história e de historiografia gerada na Europa como base para uma reflexão global. Indagando as formas como essa prática historiográfica de matriz europeia viajou e foi apropriada em diferentes contextos, nossa pesquisa procura explorar as possibilidades de pensar a dinâmica centro-periferia para a produção do conhecimento histórico. Concomitantemente, o artigo estuda uma questão relevante colocada, em especial, pela história da historiografia preocupada com tradições periféricas: como pensar representações do passado não-ocidentais (como as de culturas indígenas) dentro da história da historiografia, ou em relação a esta, sem estabelecer uma hierarquia de saberes que atribua à concepção europeia de história um "privilégio epistêmico", nos termos do historiador indiano Sanjay Seth.
Conceptual Readings into the Cold War: Towards Transnational Approaches from the Perspective of Latin American Studies in Eastern and Western Europe
Authors: Manke Albert , Březinová Kateřina , Blecha Laurin
Published: May 2017

Abstract This bibliographical and conceptual essay summarizes recent research in Cold War Studies in Europe and the Americas, especially on smaller states in historiographical studies. Against the background of an increasing connectedness and globalization of research about the Cold War, the authors highlight the importance of the full-scale integration of countries and regions of the 'Global South' into Cold War Studies. Critical readings of the newly available resources reveal the existence of important decentralizing perspectives resulting from Cold War entanglements of the 'Global South' with the 'Global North.' As a result, the idea that these state actors from the former 'periphery' of the Cold War should be considered as passive recipients of superpower politics seems rather troubled. The evidence shows (at least partially) autonomous and active multiple actors.

Published: May 2017

The ESRD Prospective Payment System introduced two incentives to increase home dialysis use: bundling injectable medications into a single payment for treatment and paying for home dialysis training. We evaluated the effects of the ESRD Prospective Payment System on home dialysis use by patients starting dialysis in the United States from January 1, 2006 to August 31, 2013. We analyzed data on dialysis modality, insurance type, and comorbidities from the United States Renal Data System. We estimated the effect of the policy on home dialysis use with multivariable logistic regression and compared the effect on Medicare Parts A/B beneficiaries with the effect on patients with other types of insurance. The ESRD Prospective Payment System associated with a 5.0% (95% confidence interval [95% CI], 4.0% to 6.0%) increase in home dialysis use by the end of the study period. Home dialysis use increased by 5.8% (95% CI, 4.3% to 6.9%) among Medicare beneficiaries and 4.1% (95% CI, 2.3% to 5.4%) among patients covered by other forms of health insurance. The difference between these groups was not statistically significant (1.8%; 95% CI, −0.2% to 3.8%). Conversely, in both populations, the training add-on did not associate with increases in home dialysis use beyond the effect of the policy. The ESRD Prospective Payment System bundling, but not the training add-on, associated with substantial increases in home dialysis, which were identical for both Medicare and non-Medicare patients. These spill-over effects suggest that major payment changes in Medicare can affect all patients with ESRD.
Political Representation, Imperial Dependency and Political Transfer: Finland and Sweden 1809–1819

Political Representation, Imperial Dependency and Political Transfer: Finland and Sweden 1809–1819

The article examines the post-revolutionary rearrangement in Europe by focusing on the separation of Finland from Sweden. In 1809, the eastern part of the Swedish kingdom became a grand duchy within the autocratically ruled Russian empire. Both Finland and Sweden experienced the constitutional moment which characterised the post-revolutionary and post-Napoleonic Europe, but in very different ways. The Swedish Diet enacted a new written constitution while the Finnish Diet gave its oath to the new emperor, who promised to maintain the laws, privileges and rights of the country. Alexander I might have used the word «constitution» in his speech to the Finnish Estates, but the political status of the grand duchy remained unclear, and it was only in 1863 that the Finnish Diet was called to convene again. In the context of imperial dependency and a lack of established forums for public debate, the article analyses how the issue of political representation was made public in Finland during the first decade of Russian rule. The analysis is based on the ways in which the official newspaper described the new political situation of Finland and reported on political circumstances and parliamentary life in other countries. It is argued that the publication of news from abroad can be seen as an important way of keeping the issue of political representation alive in Finland. It was also a channel for the reception of political concepts. The study discusses the Finnish case in relation to political circumstances in Sweden. The comparative angle draws attention to complex features of the formation of a new polity and a reformation of an old.

Ante  la situación que presentan los niños y niñas del mundo, sobre todo  los  de los países en desarrollo,  se establecen, con la participación de 189 países miembros de las Naciones Unidas, en el 2000, seis Objetivos de Desarrollo del Milenio dirigidos a la infancia. Uno de ellos pretende asegurar para el 2015 que todos los niños y niñas terminen la enseñanza primaria.

Una serie de factores individuales y estructurales  impiden el acceso o permanencia de los niños y niñas en la escuela, sin embargo, de acuerdo a una serie de estudios realizados, los factores externos, como la pobreza, y el género resultan ser los factores clave que mantiene a los niñ@s alejad@s de la escuela.

El presente trabajo tiene por objetivo mostrar los resultados de un estudio exploratorio realizado desde el enfoque mixto sobre la percepción que tienen directivos, profesores y habitantes de nueve agebs del Polígono San Bernabé, del municipio de Monterrey,  sobre los factores que promueven el rezago educativo de los estudiantes que cursan la enseñanza básica. Se dará a conocer, además, las principales estrategias utilizadas en las instituciones educativas para incidir en los factores de riesgo.

O romance Era bom que trocássemos umas ideias sobre o assunto (1995), do escritor português Mário de Carvalho, coloca em cena o próprio processo de escrita ficcional, favorecendo, assim, uma discussão sobre as convenções narrativas e sobre o papel do leitor na recepção de textos contemporâneos. Além disso, promove uma reflexão sobre o estado atual da sociedade portuguesa mediada pela ironia e pelo humor, o que justifica a base teórica eleita para a análise que apresentamos: o texto “Ironia, humor e fingimento literário” (1995), de Lélia Parreira Duarte.

Authors: B. Sunil , N. Girish , Bhuyan Manali
Published: May 2017

Background: Continuous positive airway pressure (CPAP) has become a useful modality in management of respiratory distress in preterm babies. Nasal CPAP was found to be safe and effective means of treating mild and moderate RDS and apnoea of prematurity; Continuous Positive Airway Pressure (CPAP) is a cost-effective and minimal invasive respiratory support for the newborn. The aim of the study was to assess whether the introduction of continuous positive airway pressure (CPAP) results in improved respiratory outcomes in preterm neonates ≤36 weeks of gestation in KIMS hospital.Methods: The study was an observational clinical study, undertaken in KIMS hospital, Bangalore, Karnataka, between November 2015 to October 2016. All babies born ≤36 weeks of gestational age with respiratory distress were included in this study. Chi-square/ Fisher Exact test has been used to find the significance of study parameters on categorical scale between two or more groups and Non-parametric setting for Qualitative data analysisResults: Seventy-seven premature newborn babies with ≤36 weeks of gestation were included in the study and were put on nasal CPAP. The incidence of CPAP failure was 22.1% (95% CI 14.27-32.54%). The proportion of neonates who required surfactant was 16.9% (10.14-26.77%) and the proportion of children who met with mortality was 6.5% (10.14-26.77%) in this study.Conclusions: Early institution of CPAP in the management of RDS in premature neonates can significantly reduce the need for mechanical ventilation (MV) and surfactant therapy.

Published: May 2017

Parkinson's disease (PD) can be caused by genetic changes in a lot of genes. The effect of these changes is determined by the nature of the mutation and ranges from weak associations to pathogenic mutation which leads to loss of protein function. Our study is based on epidemiological data which show significantly increased prevalence of PD (2.9 %) in an isolated population of South-Eastern Moravia in the Czech Republic. We compared two different Next Generation Sequencing (NGS) data analysis approaches in DNA from 28 PD patients in the genes responsible for Parkinsonism (ADH1C, ATP13A2, EIF4G1, FBXO7, GBA + GBAP1, GIGYF2, HTRA2, LRRK2, MAPT, PARK2, PARK7, PINK1, PLA2G6, SNCA, UCHL1 and VPS35) using: 1) already described missense rare variants or pathogenic mutations 2) twelve control DNA samples from the same isolated population. Ion Torrent NGS data processing and trimming from Fastaq through “bam” to “vcf” files was done parallely by Torrent Suite/Ion Reporter and NextGENe software. After filtering out, three missense mutations were found in LRRK2 gene: rs33995883 in 6/0 patients/control (p/c); rs33958906 in 1/1p/c; rs781737269 in 3/0p/c; one missense mutation in MAPT gene rs63750072 in 6/1p/c; and one mutation in HTRA2 gene rs72470545 in 3/1p/c. Both the results from NextGENe with Ion Torrent adaptation and from Ion Reporter significantly correlated in variant calling. Our study may contribute to further explain the genetic background of Parkinsonism.

Background: Alternative therapeutic approaches have been explored to modulate host response to periodontal disease. Knowledge of new strategies to treat periodontitis is particularly relevant in patients presenting augmented risk to periodontitis, such as smokers. The aim of this study is to investigate the impact of resveratrol (RESV) on progression of experimental periodontitis (EP) in the presence of cigarette smoke inhalation (CSI).

Methods: Rats were assigned to one of three groups: 1) CSI+RESV (n = 20); 2) CSI+placebo (n = 20); and 3) non‐CSI (n = 20). CSI was initiated 1 week prior to initiation of RESV or placebo administration (systemically for 30 days) and was continued until the end of the study. EP was induced around the first mandibular and second maxillary molars using ligatures. Specimens from the mandible were processed for morphometric and microcomputed tomography examination of bone volume/levels. Gingival tissues surrounding mandibular molars were collected for quantification of interleukin (IL)‐1β, IL‐4, IL‐6, IL‐17, and tumor necrosis factor‐α using an assay system. Additional analyses of immunoinflammatory mediator performance (T‐helper Type 17 [Th17]/Th2 and Th1/Th2 cell levels) were performed according to Th cell responses in gingival tissues. Gingival tissues of maxillary molars were subjected to real‐time polymerase chain reaction for assessment of osteoprotegrin, runt‐related transcription factor‐2, receptor activator of nuclear factor‐kappa B ligand (RANKL), sclerostin, and Dickkopf Wnt signaling pathway inhibitor 1 levels.

Results: Higher linear alveolar bone loss (ABL) and lower interradicular bone density were detected in ligated molars in the CSI+placebo group (P <0.05). IL‐4 level was the highest, and Th17/Th2 levels were the lowest in RESV‐treated rats compared with placebo rats (P <0.05). RESV reduced expression of messenger RNA for RANKL in animals receiving CSI (P <0.05).

Conclusion: RESV inhibits EP and CSI‐induced supporting ABL and has a beneficial effect on osteo‐immunoinflammatory markers.

Pojam rada zauzima centralno mesto na kom Marks utemeljuje svoju filozofiju. Marksovo shvatanje podele rada je osnova na kom gradi kritiku kapitalističkog sistema. Razlikujući pozitivni i negativni aspekt podele rada, Marks ističe važnost odnosa između podele rada i privatnog vlasništva kao centralnog problema građanske epohe. Robni karakter proizvodnje osnovni je uzrok čovekovog otuđenja u kapitalizmu. Oslobođenje procesa rada od diktata kapitala postavlja se kao nužni uslov čovekovog oslobođenja.

Renesansno shvatanje poetike se u ovom radu razmatra s obzirom na istaknuti značaj imaginacije i inovacije u stvaranju umetničkog dela. Značaj imaginacije direktno je suprotstavljen Aristotelovom pojmu podražavanja, a njegov primat pokazuje uticaj Aristotela na renesansno razumevanje poetike, kao i osobenosti tog razumevanja u otklonu od Aristotela. Razvoj razumevanja imaginacije kao porekla poezije u radu se pored pojma podražavanja razmatra i s obzirom na pitanje estetskog zadovoljstva, te s obzirom na probleme istine i morala.

Published: May 2017

Aim: To assess the influence of different fiberglass post surface treatments on the bond strength (BS) to root dentin. Methods: Thirty bovine root canals were endodontically treated and filled with gutta-percha and AH Plus sealer. At 24 h after the endodontic filling, the post spaces were prepared with Gates-Glidden drills and #3 drills of the DC White Post system, maintaining a 4 mm apical seal. The roots were randomly divided into three groups: S (fiberglass posts treated with silane), SA (fiberglass posts treated with silane and a hydrophobic adhesive system) and SHA (fiberglass posts treated with silane, followed by drying with hot air). The posts were cemented with a selfadhesive cement (RelyX U200). The specimens were stored in distilled water at 37 °C for 24 h and subjected to the push-out test (0.5 mm/min). Data were statistically analyzed using one-way ANOVA and Tukey's test (α=0.05) Results: SA and SHA groups showed the highest BS mean values (11.29 and 10.85 MPa, respectively), while the S group presented the lowest BS mean value (7.21 MPa). S group was significantly different from SA and SAH groups. Conclusions: The surface treatment of fiberglass posts influenced BS values.

Aim: This in vitro study investigated the effect of the application of an adhesive, silane and thermal cycling (TC) on the shear bond strength (SBS) of ceramic brackets to feldspathic ceramic. Methods: 16 cylinders of feldspathic ceramic were etched with hydrofluoric acid and divided into four groups (n=4): G1 - silane, without TC; G2 – silane, with TC; G3 - adhesive, without TC; G4 - adhesive, with TC. One layer of silane was applied on the surface of cylinders in G1 and G2 e one layer of photo-activated adhesive Single Bond Universal was used in G3 and G4. Ceramic brackets were bonded using Transbond XT. The SBS data were subjected to two-way ANOVA and Tukey’s post hoc test (α=0.05). The Adhesive Remnant Index (ARI) was evaluated at 40× magnification. Results: Silane was more effective than adhesive on the SBS of the brackets to ceramic (p<0.05). TC decreased significantly the SBS values compared with the groups without TC (p<0.05). The ARI results showed predominance of score 0. Conclusions: Groups with silane showed higher SBS than groups with adhesive. TC influence significantly on the bond strength. Regarding ARI, score 0 predominated in all groups.

Aim: To test the hypothesis that there is no relationship between the amount of vestibular inclination of mandibular incisors and the appearance of gingival recession in this region. Methods: This study included 20 patients selected in accordance with the following inclusion criteria: 1. adult patients without gingival recession in the mandibular incisors before treatment (T0), 2. no previous orthodontic treatment, 3. treated without tooth extraction in the mandibular arch, 4. bonded mandibular splinting from one canine to another after the active stage of orthodontic treatment (T1), 5. no visible wear of the incisal edge of the mandibular incisors, 6. Pre- and post-treatment teleradiography and plaster casts, and plaster casts 3 years post-treatment (T2). Depending on the amount of inclination of the mandibular incisors after treatment, the sample was divided into two groups: Group 1- 10 individuals (IMPA T1-T0 ≤ 5˚) and Group 2- 10 individuals (IMPA T1-T0 > 5˚). The measurement of length of the clinical crown (LCC) of the four mandibular incisors, distance between the incisal edge and vestibular marginal gingiva were made in plaster casts at T0, T1 and T2. Results: In spite of Group 1 presenting a reduction in LCC at T2, there was no statistically significant difference in LCC in the 3 time intervals evaluated in the two groups. Conclusions: The null hypothesis was accepted. The variation in the amount of vestibular inclination of the mandibular incisors during orthodontic treatment and 3 years after conclusion of treatment did not promote the appearance of gingival recessions in this group of patients.

Temperatures are elevated, due to the presence of heat generating waste, relative humidity varies from 20% to 100%, and swelling pressures within the bentonite barrier can typically be 2-10 MPa. Here, we test the robustness of a bespoke design MEMS sensor-based monitoring system, which we encapsulate in polyurethane resin. We place the sensor within an oedometer cell and show that despite a rise in swelling pressure to 2 MPa, our relative humidity (RH) measurements are unaffected. We then test the sensing system against a traditional RH sensor, using saturated bentonite with a range of RH values between 50% and 100%. Measurements differ, on average, by 2.87% RH, and a particularly far apart for high values of RH. However, bespoke calibration of the MEMS sensing system using saturated solutions of known RH, reduces the measurement difference to an average of 1.97% RH, greatly increasing the accuracy for RH values close to 100%.

Native plants from the Brazilian Amazon Biome are rich in nutrientes, oils and fats and, therefore, represent a very important regional food resource. Althoung there is a global interest in the nutritional potential of tropical fruits, the potential of Amazonian fruits as source of essential fatty acids is still under exploited, since their composition is still understudied. 1H Magnetic Resonance Nuclear (1H NMR) is a robust spectroscopic tool to profile fatty acids components in oils. The objectives of this work were to use 1H NMR to determine the fatty acids profile and the physicochemical properties of crude oils and fats obtained from fruits of Brazilian Amazon: açaí, ata-brava, bacaba, buriti, buritirana, murici amarelo, murici vermelho, piaçaba braba, tucumanzinho, pupunha red and yellow varieties. Oils were obtained by Soxhlet extraction using hexane as a solvent. After solvent removal by rotoevaporation, the resulting oils and fats were analyzed by 1H NMR spectroscopy. Unsaturated fatty acids oleic (ω9), linoleic (ω6) and linolenic (ω3) acids were quantified in the oils and their physicochemical properties were determined. It was observed that the oils have predominately ω9 fatty acids, followed by ω6 and ω3 representatives. The physicochemical properties confirmed edibility and good quality of oils and fats present in the aforementioned Amazonian fruits.

The study was carried out to determine the profitability and resource use efficiency of poultry-egg production in Yobe State. A sample of 200 poultry-egg farmers was selected by multistage sampling technique and data were collected by using a structured questionnaire. The data were analyzed using descriptive statistics, budgetary analysis, and Stochastic Frontier Analysis techniques. The study revealed that poultry-egg production enterprise is profitable in the study area. Maximum Likelihood Estimate of coefficients of the stochastic frontier model for poultry-egg production were all positive and the parameters estimates of farm size, veterinary services, feed intake and labour were statistically significant, indicating that they contributed incrementally to the total value of poultry-egg output in the study area. Analysis of inefficiency model shows that factors influencing technical efficiency were years of experience, access to credit, cooperative membership and extension contact. Recommendations include the establishment of feed producer cooperative society, provision of adequate and timely veterinary services, and access to credit, frequent extension contacts and adult education classes for the farmers.

A ocupação irregular está associada ao acelerado processo de urbanização das grandes cidades brasileiras. O Instituto Brasileiro de Geografia e Estatística utiliza a classificação de “aglomerados subnormais” para uma parte dessa modalidade de ocupação. Na cidade de Manaus, as formas de ocupação, classificadas pelo IBGE como aglomerados subnormais, estão localizadas nas faixas de depressão, nas encostas e próximo às margens de rios que drenam uma rede hidrográfica de aproximadamente 1.017 canais. Neste contexto, são inseridos 40 bairros dos 63 existentes nesta cidade. Constituem aglomerados de pessoas que vivem em condições não propícias à habitação e reúnem populações excluídas, sem infraestrutura para serviços de saúde, segurança, transportes e educação. Para realizar este estudo, selecionamos o bairro da Redenção localizado na Micro-bacia do Gigante, visando realizar uma análise geoespacial nos aglomerados subnormais do bairro da Redenção. Primeiramente foi identificado e classificado o número de setores de aglomerados subnormais (n). Posteriormente, verificou-se que no Estado do Amazonas, que o n = 122 aglomerado subnormal e mostra a cidade de Manaus como o maior receptor de n = 51 aglomerados subnormais, em seguida aparecem Iranduba n = 10, Parintins n = 7 e Tefé n = 7 No bairro de Redenção, foram identificados 48 setores censitários, sendo 4 aglomerados subnormais, totalizando 914 domicílios.

Polymer‐coated urea reduced N leaching as compared with conventional urea.

Climatic conditions during the lantana growth affected the N uptake and N‐use efficiency.

These results can be used for water and fertilizer management for ornamental plants.

This study can be used to minimize environmental impact caused by N leaching.

Lantana (Lantana camara L.) is a popular ornamental plant in seaside communities and an annual plant in hanging baskets. This species cultivated as an annual plant in containers needs to receive fertilizers. The nutrient management in containers can be made using conventional or controlled release fertilizers. The effects of ratios among conventional urea (CU) and polymer‐coated urea (PCU), and irrigation water rates applied by evapotranspiration (ET)‐based irrigation were studied on dry weight of biomass and N uptake of lantana, N leaching, water‐use efficiency (WUE), and N‐use efficiency (NUE). Six ratios between CU and PCU (expressed in percentages) and two irrigation rates were evaluated: 0:100, 25:75, 50:50, 75:25, 100:0, and 0:0 of CU/PCU; and water volume applied by 150% of reference evapotranspiration (ETo) and 200% of ETo‐based irrigation. Two trials were conducted with environmental conditions varying between them. With greater temperatures, the cumulative number of inflorescences increased with 100% of PCU as compared with 100% of CU applied in the trial. Polymer‐coated urea (100%) as compared with CU (100%) also reduced N leaching by 64.5 and 61.5% in the first and second trial, respectively. High water volume applied (200% of ETo) increased the dry weight of biomass, N uptake, and NUE. Water volume applied by 150% of ETo‐based irrigation resulted in a reduction of 53.5 and 58.5% of N leaching in the first and second trial, respectively. The response of WUE to ratios among CU and PCU and irrigation rates was not consistent, and was influenced by climatic conditions since WUE increased 26.6% in the second trial characterized for lower temperatures.
Surface Effects on Water Storage under Dryland Summer Fallow: A Lysimeter Study
Authors: Wuest Stewart
Published: May 2017

Core Ideas

Inexpensive lysimeters can produce precise, summer‐long evaporation comparisons.

Surface soil density and tillage depth had small effects on evaporation.

Crop residue had a small effect on evaporation over long dry periods.

Crop residue had a substantial effect on evaporation following rain.

Small changes in short‐ and long‐term soil water storage can affect crop productivity in semiarid climates. To optimize tillage and residue management on silt loam soils, we compared evaporation from a range of soil surface conditions in a climate with dry summers. Sixty low‐cost, low‐maintenance lysimeters were constructed from 26‐L buckets and installed in‐ground for five summers. Three summer fallow soil management options were mimicked by packing soil uniformly to the surface, putting a loose layer of fine soil on top of the packed base, or placing a mixture of clods and fine soil on top of the base. Different amounts of wheat residue on the soil surface were also tested. With three replications, the lysimeters were capable of discriminating 0.10‐mm evaporation differences between treatments at p < 0.05. Evaporation differences were small, typically only 5 mm, at the end of each summer fallow dry season. Wheat residue on the soil surface and different soil mulch treatments had little influence on evaporation during long dry periods, but surface residue had a substantial effect on soil water storage immediately after rainfall, especially as evaporative demand decreased in early autumn. The results indicate that high levels of surface residue might be more important than tillage or no‐till in the proportion of early autumn rain being stored vs. evaporated.
Size‐Dependent Turbidimetric Quantification of Suspended Soil Colloids

Core Ideas

An efficient turbidimetric method was developed to quantify colloids in aqueous samples.

Concentration–turbidity correlations depend primarily on particle size rather than composition.

The size‐dependent correlations have practical and nearly universal applicability.

This method allows accurate and quick colloid quantification in field samples.

Mobile soil colloids play an important role in affecting soil hydraulic properties and soil formation, as well as in facilitating the transport of strongly sorbing constituents (e.g., contaminants, pesticides, nutrients) in subsurface environments. Accurate quantification of mobile colloids is thus essential for understanding and prediction of soil element migration, changes in soil hydraulic properties, and colloid‐associated contaminants in natural and managed systems. However, quantification of colloids in field samples, especially the <0.45‐μm fractions, which are traditionally considered dissolved solutes, has largely been hindered due to the lack of reliable methods. In this study, we developed a simple and efficient methodology of using size‐dependent correlations between nephelometric turbidity and mass concentrations of colloids for quantifying colloids in the <0.1‐, 0.1‐ to 0.45‐, and 0.45‐ to 1.0‐μm fractions. The correlations were measured using model colloids (latex, silica, and Fe oxide particles) and soil colloids extracted from 37 soils. We found that colloid size strongly affected concentration–turbidity relationships, while colloid composition played a less important role in shifting the correlations. The size‐dependent concentration–turbidity correlations were further tested against gravimetric measurements using additional field samples and found to be more accurate than correlations that do not consider size effects. The relatively insignificant particle composition effect indicates the practically “universal” applicability of the reported correlations. In addition, the correlations, for the first time, allow quantification of colloids in different size fractions in environmental samples. This would enhance our capability to more accurately quantify the colloidal pools in natural systems, which have strong implications for understanding the processes and mechanisms of colloid and colloid‐associated‐constituent mobilization and transport.
A Simple Representation of Plant Water Storage Effects in Coupled Soil Water Flow and Transpiration Stream Modeling

Core Ideas

A previous soil water flow model was extended to allow simulation of transient plant water storage.

Comparison with measured Norway spruce sap flow data indicates improved model performance.

The proposed algorithm can be easily incorporated into existing soil water flow models.

When describing the movement of water in a variably saturated plant root zone, most existing hydrological models use the assumption of quasi‐steady‐state flow to relate root water uptake to canopy transpiration, thereby neglecting the effect of changing plant water storage. This approach is known to be problematic, especially when considering relatively large volumes of water stored in the tissues of tall trees. We propose a simple algorithm, based on the concept of whole‐plant hydraulic capacitance, to deal with the problem. The algorithm is implemented in a one‐dimensional soil water flow model involving vertically distributed macroscopic root water uptake. In this study, the proposed transient storage approach was compared with the quasi‐steady‐state approach. Both approaches were used to simulate soil water flow and diurnal variations of transpiration at a forest site covered with Norway spruce [Picea abies (L.) H. Karst.]. The key parameter of the transient storage approach, the plant hydraulic capacitance, is estimated by comparing the variations in the potential transpiration rate, derived from micrometeorological measurements, with observed sap flow intensities. The application of the proposed algorithm leads to more realistic predictions of root water uptake rates at the site of interest. The inclusion of the plant water storage effects improved the ability of the model to capture the anticipated diurnal variations in actual transpiration rates. The algorithm can be easily implemented into existing soil water flow models and used to simulate transpiration stream responses to varying atmospheric and soil moisture conditions including isohydric and partly also anisohydric plant responses to drought stress.
