Abstract Estuaries are extremely valuable ecosystems and have been affected by several anthropogenic activities from urban growth and industrial development, such as the release of untreated efuents which decrease water quality. This study aimed to evaluate the seasonal and temporal trophic status variation in the Formoso River Estuarine System (FRES), a tropical estuary. Three campaigns were carried out in each season (rainy and dry), during which surface water was sampled for abiotic parameter analyses. The TRIX index was used for trophic status assessment. For the temporal evaluation, a review of literature addressing the matter in the study area was conducted. Between 2017 and 2018, the TRIX index varied from a mean of 6 ± 0.2 upstream to 5 ± 0.4 downstream during the rainy season, indicating eutrophic conditions throughout most of the FRES extension, especially near the Formoso River, and from 6 ± 1 to 3 ± 0.8 during the dry season. Temporal analyses showed that in 2002 the overall mean TRIX index was 5.72 ± 0.4, decreasing in 2005 and 2014, and followed by an upwards trend. We conclude that the FRES is impacted by the release of untreated efuents such as sewage and fertilizers from the city of Rio Formoso and from various agricultural activities, which are more intense during the rainy season. Nevertheless, over time there were more critical scenarios pertaining to the trophic status. The present diagnosis reinforces the importance of public sanitation policies in estuarine regions and spatial planning instruments for pollution control in fishery areas.

ABSTRACT BACKGROUND: Obstructive sleep apnea (OSA) is characterized by recurrent pharyngeal wall collapse during sleep caused by anatomical or functional changes associated with obesity or dislocation of maxillofacial structures. OBJECTIVE: To determine the major risk factors for obstructive sleep apnea monitored in the home. DESIGN AND SETTING: Cross-sectional study conducted in a private clinic in Fortaleza (CE), Brazil. METHODS: Between 2015 and 2018, 427 patients were screened for OSA with home-based monitoring, yielding 374 positives. Information was collected on age, sex, body mass index (BMI), hypertension, diabetes (DM), dyslipidemia, coronary artery disease (CAD), arrhythmia, peripheral artery occlusive disease (PAOD), heart failure (HF) and lung disease. The home sleep apnea test result was then compared with the clinical diagnosis. Lastly, parameters identified as significant in the univariate analysis were subjected to multivariate logistic regression. RESULTS: Male sex predominated, although not significantly. OSA was associated with hypertension, DM, dyslipidemia, age and BMI. The risk of OSA being associated with these parameters was 2.195 (hypertension), 11.14 (DM), 2.044 (dyslipidemia) and 5.71 (BMI). The association was also significant for BMI categories (normal, overweight or obese). No significant association was observed for CAD, arrhythmia, PAOD, HF or lung disease. After multivariate logistic analysis, only age and BMI (and its categories) remained significant. CONCLUSION: OSA was associated with hypertension, DM, dyslipidemia, age and BMI in univariate analyses, but only with age and BMI (and its categories) in multivariate logistic analysis.

ABSTRACT Oxisols are important soils that have been converted from native vegetation to croplands, and can affect soil biological properties such as microbial biomass and enzyme activity. Thus, the aim of this study was to evaluate the changes on soil microbial biomass and enzyme activity when native vegetation (NV) was converted to cropland (CL), such as maize or sugarcane in six oxisols from São Paulo state, Brazil. Soil microbial biomass C (MBC) and N (MBN), and the activity of arylsulphatase, dehydrogenase and fluorescein diacetate hydrolysis (FDA) were assessed in samples collected at 0-0.20 m. In general, MBC was higher under NV than CL (about + 40%), while MBN and FDA did not show a consistent pattern between NV and CL. All soils showed higher values of arylsulfatase (increased from 101 to 717%) and dehydrogenase (increased 15 to 220%) under NV than CL. In conclusion, soil microbial biomass C is usually higher under native vegetation than cropland. Arylsulphatase and dehydrogenase were the attributes that presented better differentiation between native and cropped soils.

RESUMO Desde o final do século vinte, 100% do esgoto urbano da cidade de Jaboticabal é recolhido por interceptores e conduzido a uma estação de tratamento. Entre 1999 e 2000, estudos sobre o efeito desse cuidado ambiental, mostraram que a coleta de esgoto ainda não tinha sido eficiente para despoluir as águas dos dois córregos que atravessam a cidade e fluem para uma área agrícola. Neste trabalho avalia-se a influência do uso do solo na qualidade da água destes dois córregos. O estudo foi realizado 15 anos após a implantação dos interceptores de esgoto. Durante o ano de 2014, bimestralmente, coletaram-se amostras de água em oito pontos (P1 a P8), dos córregos Cerradinho e Jaboticabal, em Jaboticabal (SP, Brasil). P1 estava localizado na nascente do córrego Jaboticabal; P2 em área agrícola; P3, P4 e P5 em área urbana; P6, P7 e P8 em área agrícola. Foram determinadas variáveis físicas e químicas e a comparação metabólica da população microbiana em diversas fontes de carbono pelo método EcoPlate (Biolog). Em todos os pontos e coletas, o teor de fósforo total excedeu o limite estabelecido pela legislação brasileira, assim como valores encontrados em estudos anteriores, o que também foi observado em relação à demanda química de oxigênio. Entretanto, a população microbiana da água parece não estar sendo alterada pelas atividades urbanas e agrícolas. Os resultados das análises sinalizam à possibilidade de descarga clandestina de águas residuárias nos córregos estudados e à influência do uso agrícola do solo.

ABSTRACT Since the end of the twentieth century, 100% of the urban sewage from the city of Jaboticabal has been collected by interceptors and routed to a treatment plant. Between 1999 and 2000, studies on the effect of this environmental care showed that it did not efficiently clean up the water from the two streams that run through the city and flow into an agricultural area. This paper focuses on assessing the influence of soil use on the water quality of surface waters from these two streams. The study was conducted 15 years after the implementation of sewage interceptors. The sampling dates were bimonthly at eight points (P1 to P8) in the Cerradinho and Jaboticabal streams, in Jaboticabal (São Paulo State, Brazil). P1 was located at the source of the Jaboticabal stream, P2 was in a farming area, P3, P4 and P5 were in an urban area, and P6, P7 and P8 were in a farming area. The physical and chemical variables of the water were assessed. We compared the ability of microorganisms to metabolize different sources of carbon using the EcoPlate (Biolog). The total phosphorus (TP) concentration exceeded the limit set by the Brazilian legislation as well as values found in previous studies, which was also observed for the chemical oxygen demand. However, the bacterial metabolic profile had no association with urban or farming practices. The results of the analysis indicated the possibility of clandestine discharge of wastewater in the streams studied and the influence of the agricultural soil.

RESUMO A grande produção de lodo de esgoto (LE), principalmente em grandes centros urbanos, tem sugerido a disposição desse resíduo como fertilizante na agricultura. Trata-se de uma ação de grande viabilidade econômica, além de contribuir para melhorar o meio ambiente pela ciclagem dos nutrientes presentes nesse resíduo, que possui elevado teor de matéria orgânica e de nutrientes para as plantas. O objetivo deste estudo foi avaliar atributos químicos e bioquímicos de dois Latossolos Vermelhos, um Eutroférrico (LVef) e outro Distrófico (LVd), cultivados com milho, após aplicação do LE em diferentes doses por 16 anos. O experimento foi instalado em condições de campo em Jaboticabal, São Paulo. O delineamento experimental foi em blocos casualizados com quatro tratamentos e cinco repetições. Os tratamentos foram: T1 = testemunha (fertilização mineral, sem aplicação de LE), T2 = 5 Mg ha-1 de LE, T3 = 10 Mg ha-1 de LE e T4 = 20 Mg ha-1 de LE (base seca). Os resultados obtidos para os diferentes atributos avaliados foram submetidos à análise da variância e utilizou-se o teste de Duncan para comparação de médias (p≤0,05). O lodo de esgoto aumentou o P extraído pelo método da resina em ambos os Latossolos, e o teor de matéria orgânica no Latossolo Vermelho Distrófico. Na dose 20 Mg ha-1, base seca, o resíduo promoveu aumento na atividade da fosfatase ácida no Latossolo Vermelho Eutroférrico, respiração basal e quociente metabólico no Latossolo Vermelho Distrófico. A dose 20 Mg ha-1 de lodo de esgoto, base seca, não alterou a biomassa microbiana em ambos os Latossolos e aumentou a produção de grãos no Latossolo Vermelho Eutroférrico, sem causar sintomas de fitotoxicidade ou deficiência nutricional nas plantas.

ABSTRACT The large production of sewage sludge (SS), especially in large urban centers, has led to the suggestion of using this waste as fertilizer in agriculture. The economic viability of this action is great and contributes to improve the environment by cycling the nutrients present in this waste, including high contents of organic matter and plant nutrients. This study evaluated the chemical and biochemical properties of Dystrophic and EutroferricLatossolos Vermelhos (Oxisols) under corn and after SS application at different rates for 16 years. The field experiment was carried out in Jaboticabal, São Paulo State, Brazil, using a randomized block design with four treatments and five replications. Treatments consisted of control - T1 (mineral fertilization, without SS application), 5 Mg ha-1 SS - T2, 10 Mg ha-1 SS - T3, and 20 Mg ha-1 SS - T4 (dry weight base). The data were submitted to variance analysis and means were compared by the Duncan test at 5 %. Sewage sludge increased P extracted by resin in both theLatossolos Vermelhos, Dystrophic and Eutroferric, and the organic matter content in the Dystrophic Latossolo Vermelho. The waste at the rate 20 Mg ha-1 on a dry weight basis promoted increases in acid phosphatase activity in Eutroferric Latossolo Vermelho, basal respiration and metabolic quotient in DystrophicLatossolo Vermelho. The rate 20 Mg ha-1 sewage sludge on a dry weight basis did not alter the soil microbial biomass in both the Latossolos Vermelhos; in addition, it improved corn yields without inducing any symptoms of phytotoxicity or nutrient deficiency in the plants.

A avaliação da qualidade ambiental assume grande importância em programas de recuperação de áreas degradadas, razão pela qual se faz necessário o desenvolvimento de sistemas quantitativos, com base em combinação de indicadores que melhor representem as condições de degradação ou recuperação em curso. O presente trabalho utiliza-se de parâmetros biológicos do solo como a biomassa microbiana e a atividade de desidrogenase, além da análise do material vegetal, para verificar a influência do plantio sucessivo de leguminosas em um solo minerado em processo de recuperação. A atividade microbiana foi determinada a partir da quantificação do carbono e o nitrogênio da biomassa microbiana (BMC e BMN respectivamente), da atividade da desidrogenase e da hidrólise do FDA avaliadas em uma área de piso de lavra após um, dois e três anos de plantio consecutivos de leguminosas e de uma área de deposição de rejeito após um ano de plantio de um mistura de leguminosas: feijão guandu, mucuna preta e crotalária juncea, comparados com o solo sob mata e com áreas sem plantio. O uso dos indicadores biológicos: biomassa microbiana e atividade de desidrogenase, e da análise do material vegetal na avaliação das técnicas e estratégias de recuperação adotadas revelaram que o plantio de leguminosas e sua posterior incorporação vêm promovendo alterações graduais positivas no solo degradado, principalmente em relação à BMC em áreas após o plantio consecutivo de três anos de leguminosas.

The evaluation of the environmental quality assumes great importance in recovery programs of degraded areas, which makes necessary the development of quantitative systems based on combinations of indicators that best represent the degradation or the ongoing recovery conditions. This work uses soil biological parameters, such as microbian biomass and dehydrogenase activity, in addition to the analysis of the plant material to verify the influence of the successive planting of legumes in a mined soil undergoing recovery. The microbian activity was determined through the quantification of the microbian biomass' carbon and nitrogen (BMC e BMN), the dehydrogenase activity and FDA hydrolysis, evaluated in a mine pit area after one, two and three years of consecutive planting of legumes, and in a tailing area after one year of planting a mixture of legumes (pigeon peas, velvet beans and sunn hemp). Those areas were compared to forest soil and areas with no planting. The use of biological indicators (microbian biomass and dehydrogenase activity) and the analysis of plant material in the evaluation of the adopted techniques and strategies revealed that the planting of legumes and its further incorporation promoted positive and gradual modifications in the degraded soil, mainly in the BMC in areas after the consecutive planting of legumes over the course of three years.

O presente trabalho teve como objetivo avaliar: (a) Uso de leguminosas e gramíneas utilizadas na adubação verde; (b) Incorporação de matéria orgânica pela adição de compostos orgânicos e (c) Efeitos da adubação química e calagem na recuperação de áreas degradadas pela mineração de cassiterita na FLONA do Jamari (RO). O experimento foi instalado em dezembro de 1999. O delineamento experimental adotado foi em blocos casualizados com 24 tratamentos no esquema fatorial 6 X 4, constando de seis tipos de coberturas vegetais (Brachiaria humidicula (Braquiária), Cajanus cajan (Feijão guandu), Mucuma aterrima (Mucuna preta), Cajanus cajan (Feijão guandu) + Brachiaria humidicula (Braquiária); Mucuma aterrima (Mucuna preta)+ Brachiaria humidicula (Braquiária) e solo nu e quatro tipos de adubação na cova (NPK 10-10-10; 50% rejeito + 50% composto; 50% rejeito + 50% composto + NPK 10-10-10; 50% rejeito + 50% composto + NPK 10-10-10 + calcário dolomítico). As amostras de solo foram coletadas superficialmente (0-20 cm) para fins de análises químicas e físicas, 15 meses após o plantio, logo após as chuvas. Os resultados foram submetidos à análise de variância (p < 0,05) e, nos casos em que o teste F foi significativo, aplicou-se o teste Tukey para a comparação das médias de seis repetições Apenas nas características químicas foram observadas diferenças significativas entre os tratamentos. As adubações química e orgânica e a calagem contribuíram para essas diferenças, e os tratamentos que receberam calcário proporcionaram como esperado aumento no pH, nos teores de Ca, Mg, na CTC, SB e V% e diminuição no H+Al quando comparados aos demais. Porém, quando se analisa o teor de matéria orgânica e os parâmetros físicos estudados não houve diferenças entre os tratamentos, mesmo naqueles onde a adubação foi intensiva associada ao plantio de adubos verde e a gramíneas indicando que as melhorias nos atributos físicos do solo em áreas de deposição de rejeito deve ocorrer de forma mais lenta.

This work had the goal of evaluating (a) The use of legumes and grasses employed in green fertilizing; (b)The incorporation of organic matter through the addition of organic compounds and (c) The effects of chemical fertilizing and lime application in the recovery of areas degraded by tin mining in the Jamari National Forest (RO). The experiment was set up in December, 1999. The experimental design adopted consisted of casualized blocks with 24 treatments according to a 6x4 factorial scheme, composed by six types of plantcoverage (Brachiaria humidicula, Cajanus cajan, Mucuna aterrima, Cajanus cajan + Brachiaria humidicula, Mucuna aterrima + Brachiaria humidicula, and bare soil), and four types of fertilizer in the pit (NPK 10-10-10; 50% tailing + 50% compound; 50% tailing + 50% compound + NPK 10-10-10; 50% tailing + 50% compound + NPK 10-10-10 + dolomite lime. The soil samples were collected superficially (0-20 cm) and used for chemical and physical analyses in 144 installments, 15 months after planting, right after the rains fall periods. The results were submitted to analysis of variance (p < 0,05) when test F proved significant, the Tukey test was applied for comparison of the averages of six repetitions. The chemical characteristics were the only ones to present significant differences between treatments. The chemical and organic fertilizing, as well as the lime application, contributed for these differences, and the treatments that received lime presented a series of improvements in soil, such as an increase in pH, in the levels of Ca, Mg, in CTC, SB and V% and a decrease in H+Al when compared to the others. However, when the level of organic matter was analyzed, the physical parameters and the biological aspects studied did not present differences between treatments, even in those where fertilizing was intensively associated to the planting of green manure and the introduction of forest species, indicating that the improvements in the physical attributes of the soil in tailing areas must happen at a slower pace.

OBJECTIVE: Using strain gauge (SG) analysis, the aim of this in vitro study was quantify the strain development during the fixation of three-unit screw implant-supported fixed partial dentures, varying the types of implant-abutment joints and the type of prosthetic coping. The hypotheses were that the type of hexagonal connection would generate different microstrains and the type of copings would produce similar microstrains after prosthetic screws had been tightened onto microunit abutments. MATERIALS AND METHODS: Three dental implants with external (EH) and internal (IH) hexagonal configurations were inserted into two polyurethane blocks. Microunit abutments were screwed onto their respective implant groups, applying a torque of 20 Ncm. Machined Co-Cr copings (M) and plastic prosthetic copings (P) were screwed onto the abutments, which received standard wax patterns. The wax patterns were cast in Co-Cr alloy (n=5), forming four groups: G1) EH/M; G2) EH/P; G3) IH/M and G4) IH/P. Four SGs were bonded onto the surface of the block tangentially to the implants, SG 1 mesially to implant 1, SG 2 and SG 3 mesially and distally to implant 2, respectively, and SG 4 distally to implant 3. The superstructure's occlusal screws were tightened onto microunit abutments with 10 Ncm torque using a manual torque driver. The magnitude of microstrain on each SG was recorded in units of microstrain (µε). The data were analyzed statistically by ANOVA and Tukey's test (p<0.05). RESULTS: Microstrain values of each group were: G1= 338.1±223.0 µε; G2= 363.9±190.9 µε; G3= 415.1±53.5 IE; G4= 363.9±190.9 µε. No statistically signifcant difference was found between EH and IH, regardless of the type of copings (p>0.05). The hypotheses were partially accepted. CONCLUSIONS: It was concluded that the type of hexagonal connection and coping presented similar mechanical behavior under tightening conditions.

Poucas cultivares de coentro (Coriandrum sativum L.) estão disponíveis aos produtores e, em algumas regiões, cultivam-se genótipos de origem desconhecida, mantidos pelos próprios hortelãos. Para conservar as cultivares tradicionais é necessário não só coletá-las e conservá-las, mas também caracterizá-las. Dessa forma, este trabalho teve por objetivo determinar caracteres morfológicos para diferenciar genótipos de coentro no processo de registro de cultivares. Foram realizados dois experimentos, ambos em blocos casualizados, com cinco repetições. As cultivares Americano, Asteca, Palmeira, Português, Santo, Supéria, Tabocas, Tapacurá e Verdão, além da linhagem HTV-9299 foram analisadas para caracteres de fruto, plântula, folhas, folíolos e flores. Os dados obtidos foram submetidos à análise de variância univariada. A cultivar Palmeira apresentou frutos de maior tamanho e massa. Já para antocianina a cultivar Americano apresentou menor intensidade, ou praticamente ausência do pigmento tanto nas plântulas quanto nas plantas, ao contrário da cultivar Tabocas que apresentou maior intensidade. As cultivares Americano, Tabocas, Palmeira, Asteca, Verdão e Tabocas e a linhagem HTV-9299 possuem maior número de folhas basais, no entanto, as cultivares que produziram maior quantidade de massa por planta foram Tabocas, Palmeira, Verdão, HTV-9299 e Tapacurá. A cultivar Americano possui folíolo verde claro pouco amarelado, a linhagem HTV-9299 folíolo verde e a cultivar Tabocas folíolo verde escuro. Os descritores morfológicos com maior poder discriminatório para o grupo de dez cultivares avaliadas foram tamanho e massa de fruto; antocianina na plântula e planta; número de folhas basais; comprimento da quinta folha; tamanho e coloração de folíolo; número de dias para pendoamento e abertura da primeira flor e massa da planta fresca.

Few coriander cultivars (Coriandrum sativum L.) are available to producers and, in some regions, are grown genotypes of unknown origin, kept by the growers themselves. To conserve such traditional crops it is necessary to collect, save, and characterize them. Thus, this study was to determine morphological characters to differentiate coriander genotypes aiming the registration of cultivars. Two trials were carried out, and the experimental design used in both was in completely randomized blocks with five replications. Americano, Asteca, Palmeira, Português, Santo, Superia, Tabocas, Tapacurá, and Verdão cultivars, and the line HTV-9299 were characterized for seedling, leaflets, leaves, fruits, and flowers. The data were subjected to a univariate ANOVA. The fruits of cv. Palmeira exhibited greater size and mass. As regards the presence of anthocyanins in seedlings and plants, cv. Americano showed the lowest intensity or slight pigmentation while cv. Tabocas had the highest pigmentation. The cultivars Americano, Palmeira, Asteca, Verdão, and Tabocas and the line HTV-9299 displayed higher number of basal leaves, however, the genotypes that produced larger amount of mass per plant were Tabocas, Palmeira, Verdão, HTV-9299, and Tapacurá. The green tone of leaflets showed differences among cultivars. So, cv. Americanos leaflets exhibited a light green, slightly yellowish color, HTV-9299 green, and Tabocas dark green. The morphological traits with higher discriminatory power for the group of the ten evaluated cultivars were: size and weight of fruits; presence or absence of anthocyanin in seedlings and plants; number of basal leaves; length of the fifth leaf; size and color of leaflets; number of days to bolting initiation, and opening of the first flower, and plant fresh mass.

Abstract: Pt En | Text: Pt En | PDF: Pt | PDF: En

Avaliaram-se sete genótipos de coentro, sendo cinco linhagens (HTV 9299, HTV 7299, HTV 0699, HTV 0999 e HTV 0199) e duas cultivares comerciais (Verdão e Palmeira), de maio a julho de 2003 no município de Areia-PB, em delineamento de blocos casualizados em quatro repetições. As cultivares Verdão (5,0 kg m-2) e Palmeira (4,3 kg m-2) e as linhagens HTV 9299 (4,4 kg m-2), HTV 7299 (4,5 kg m-2) e HTV 0999 (4,3 kg m-2), apresentaram as maiores produções de massa verde (PMV), enquanto a linhagem HTV 0199, com produção de 2,9 kg m-2, foi a menos produtiva. As linhagens HTV 7299 (0,73) e HTV 0199 (0,81) apresentaram os mais elevados valores para a relação folhas:talos. As cultivares Verdão e Palmeira e as linhagens HTV 7299, HTV 0999, HTV 0699 e 9299 apresentaram 65; 58; 35; 29; 40 e 59%, respectivamente, de plantas pendoadas aos 42 dias após a semeadura, enquanto a linhagem 0199 apresentou apenas 11%. A linhagem HTV 7299 pode ser uma alternativa para os produtores de coentro da região de Areia.

Seven coriander genotypes were evaluated (lines HTV 9299, HTV 7299, HTV 0699, HTV 0999,HTV 0199 and cvs. Verdão and Palmeira), in Areia County, Paraiba State, Brazil, from May to July of 2003 in randomized blocks in four replications. Verdão (5,0 kg m-2) and Palmeira (4,3 kg m-2) cultivars and the lines HTV 9299 (4,4 kg m-2), HTV 7299 (4,5 kg m-2) and HTV 0999 (4,3 kg m-2), exhibited the greatest yield of green mass (GM), while the line HTV 0199, with 2.9 kg m-2 of GM, showed the lowest yield. Lines HTV 7299 (0.73) and HTV 0199 (0.81) presented the largest values for the ratio leaves:stalks. Verdão and Palmeira cultivars and lines HTV 7299, HTV 0999, HTV 0699 and 9299 persented 65; 58; 35; 29; 40 and 59%, respectively, of plant bolting (PB) at 42 days after sowing date, while Line HTV 0199 presented only 11%. Line HTV 7299 might be an alternative for coriander cropping in Areia.
