1. Gas exchange, root hydraulic conductivity, water use efficiency and the growth of Toona ciliata clones and seedlings
Resumo As plantações florestais estabelecidas com mudas apresentam heterogeneidade e dificuldades de manejo. Assim, uma alternativa a estes obstáculos é o uso de clones com alta produtividade. Além disso, as plantas clonais diferem das plantas seminíferas na estrutura do sistema radicular, o que pode influenciar a eficiência na absorção de água e d

2. Effect of two desensitizing agents on dentin permeability in vitro
Abstract Objective The aim of this in vitro study was to investigate the effect of two desensitizing agents and water on hydraulic conductance in human dentin. Material and Methods GLUMA Desensitizer PowerGel (GLU) contains glutaraldehyde (GA) and 2-hydroxyethyl methacrylate (HEMA), and Teethmate Desensitizer (TD) is a powder comprising tetracalcium phos

3. Rootstocks induce contrasting photosynthetic responses of orange plants to low night temperature without affecting the antioxidant metabolism
Low temperatures negatively impact the metabolism of orange trees, and the extent of damage can be influenced by the rootstock. We evaluated the effects of low nocturnal temperatures on Valencia orange scions grafted on Rangpur lime or Swingle citrumelo rootstocks. We exposed six-month-old plants to night temperatures of 20ºC and 8ºC under controlled condi

4. Effect of adhesive system and application strategy on reduction of dentin permeability
This study evaluated the effect of adhesive systems and application strategies on dentin hydraulic conductance (HC). The buccal enamel was removed from bovine incisors to simulate laminate cavity preparations. After removing the roots and the coronal pulp, the buccal dentin was treated with EDTA solution (0.5 M) for 5 minutes, rinsed, ultrasonicated for 12 m

5. Reanálise CFSR-NCEP aplicada ao modelo SiB2 na simulação de fluxos de CO2 sobre o cultivo de soja em Cruz Alta.
The present work aimed to evaluate the behavior of CO2 fluxes, run by the Simple Biosphere Model (SiB2), by adopting CFSR-NCEP data reanalyzed as an atmospheric boundary condition. A statistical analysis was used in order to validate the results obtained using a coefficient for the adjusted model based on the simulation parameters when compared to the data o

6. Effect of propolis gel on the in vitro reduction of dentin permeability
OBJECTIVE: The aim of this study was to evaluate the capacity of potassium oxalate, fluoride gel and two kinds of propolis gel to reduce the hydraulic conductance of dentin, in vitro. MATERIAL AND METHODS: The methodology used for the measurement of hydraulic conductance of dentin in the present study was based on a model proposed in literature. Thirty-six 1

7. Análise quantitativa e qualitativa da condutividade hidráulica da dentina após tratamento com diferentes agentes dessensibilizantes. Estudo in vitro / Quantitative and qualitative analysis of the dentin hydraulic conductance after treatment with different desensitizing agents. In vitro study
O tratamento das lesões cervicais não cariosas hipersensíveis com agentes dessensibilizantes pode ser uma opção prática e eficaz devido, principalmente, à capacidade desses produtos de obliterarem os túbulos dentinários expostos. Portanto, o objetivo deste estudo foi analisar, in vitro, o efeito quantitativo e qualitativo de cinco agentes dessensibi

8. Effects of fertirrigation with effluent of primary treatment of wastewater from swine on the soil and in the productivity and quality of tomato (Lycopersicon esculentum Mill.) / Efeitos da fertirrigação com efluente do tratamento primário da água residuária da suinocultura no solo e na produtividade e qualidade do tomate (Lycopersicon esculentum Mill.)
In this study was analyzed the effects of fertirrigation with filtrated wastewater from swine (FWS) on soil and the physiological, sanitary variables and of tomato production, in drainage lysimeters under protected environment. The experiment was carried out in the lysimeter station at the Hydraulic, Irrigation and Drainage Experimental Area, in campus of th

9. Influence of intrapulpal pressure simulation on the bond strength of adhesive systems to dentin
The purpose of this study was to evaluate the influence of intrapulpal pressure simulation on the bonding effectiveness of etch & rinse and self-etch adhesives to dentin. Eighty sound human molars were distributed into eight groups, according to the permeability level of each sample, measured by an apparatus to assess hydraulic conductance (Lp). Thus, a simi

11. Morphology, relations water and photosyntheses in two cultivate of Coffea canephora submitted the of water déficit / Morfologia, relações hídricas e fotossíntese em duas cultivares de Coffea canephora submetidas ao déficit hídrico
In this study we aimed to expand our earlier understanding on the mechanisms associated with drought tolerance within Coffea canephora. Two cultivars of C. canephora, robusta (drought-sensitive) and kouillou (drought-tolerant) were grown in 24-L pots until 12-month old, when an irrigation and a drought treatment were applied. Plants were droughted until pred

12. Effects of a potassium oxalate gel/adhesive agent combined application on dentin permeability: an in vitro study / Avaliação in vitro dos efeitos da aplicação de sistemas adesivos, do oxalato de potássio, ou a combinação de ambos, na permeabilidade dentinária
There is an ongoing trend to move away from classical multi-component bonding systems toward simplified adhesives. An immediate consequence of adhesive simplification is the intrinsic permeability to water that result from their increase in hydrophilicity. Current studies have demonstrated that single-step adhesives may act as semi-permeable membranes that a
