1. Management of rice straw in rice-soybean succession in tropical lowland
ABSTRACT This study aimed to analyze rice straw alternative managements to maximize the rice-soybean succession yield and to quantify their impacts on soil properties. The experiment was set up in a completely randomized design with six replicates. Nine rice straw managements were evaluated: straw burning (M1), straw harvesting (M2), straw incorporation with

2. Influence of bottom ash and red mud additions on self-leveling underlayment properties
Abstract Self-levelling underlayments (SLUs) based on Portland cement (PC) are susceptible to cracking due to drying shrinkage. The present study evaluated the influence of binder contents on systems consisting of calcium aluminate cement (CAC), PC, and a source of calcium sulfate (C$), derived from the flue gas desulfurization process (FGD), on the mechanic

3. Prostatic alterations associated to early weaning and its relation with cocoa powder supplementation. Experimental study in adult wistar rats
ABSTRACT Early weaning can predispose the offspring to greater risk of developing chronic diseases in adulthood. It is believed that the consumption of functional foods is able to prevent these effects. The aim of this study is to evaluate the effects of maternal and postnatal cocoa powder supplementation on body mass, metabolism, and morphology of the prost

4. Influence of the physical characteristics of sand and the crushed filler content on the properties of self-leveling mortars
Abstract The properties of self-leveling mortars (SLMs) in the fresh and hardened state are strongly affected by their formulation. In this study, the influence of three different quartz sands (different physical characteristics) was investigated in SLMs, as well as the replacement of these sands by crushed basalt filler. The tests performed were: spreading,

5. Ternary system Portland cement-calcium aluminate cement-calcium sulfate applied to self-leveling mortar: a literature review
Abstract The modernization of building systems is increasingly demanding products that improve efficiency during their processing. The development of self-leveling mortars for the regularization of flooring is a consequence of this evolution. The high contents of binder and water to obtain self-flowing property, plus the application of thin layers over large

9. OUTLIER=GROSS ERROR? DO ONLY GROSS ERRORS CAUSE OUTLIERS IN GEODETIC NETWORKS? ADDRESSING THESE AND OTHER QUESTIONS
Abstract This article has theoretically discussed some points regarding outliers caused by errors in geodetic observations (see consideration made). Comments have also been made on the usual 3σ-rule to identify outliers and its common approachs in the simulation of outliers in geodetic networks. Three simulated experiments have been conducted to verify the

10. Soil compaction on traffic lane due to soil tillage and sugarcane mechanical harvesting operations
ABSTRACT: Mechanical sugarcane harvesting increases soil compaction due to the intense traffic of agricultural machinery, reducing longevity of sugarcane crops. In order to mitigate the harmful effects caused by agricultural traffic on the soil structure in sugarcane fields, this study evaluated impacts of mechanical sugarcane harvesting on traffic lane unde

12. PHYSICAL CONNECTION BETWEEN BVRF SEGMENTS BASED ON LEVELING ASSOCIATED WITH GRAVIMETRY
Resumo Considerando os esforços no estabelecimento de Sistemas de Referência Globais vinculados ao geopotencial, buscam-se novas alternativas para abordar os problemas apresentados nas redes verticais clássicas nacionais. A Rede Vertical de Referência do Brasil (RVRB) foi materializada em dois segmentos distintos, com origens independentes (marégrafos d
