The objective of this work was to evaluate the adaptability of different lettuce (Lactuca sativa) cultivars grown in no-tillage on straw of ruzi grass (Urochloa ruziziensis), as well as its effects on soil temperature and weed control, in successive cultivations in the summer. The treatments were carried out in a randomized complete block design, with four replicates, in a split-plot arrangement (2x4), in which soil management (no-tillage on ruzi grass and convention tillage) was the main plot, and the different crisphead lettuce cultivars (Amanda, Solaris, Vanda, and Vera), the subplots. No difference was observed between cultivars for soil management. No-tillage reduced the soil temperature by up to 3.7°C and weed density by 3.7 times, in comparison with conventional tillage. Ruzi grass promoted a greater bed conservation. In comparison to with conventional tillage, the no-tillage management of lettuce cultivated on ruzi grass straw resulted in a lower yield in the first crop due to excess straw; in a similar yield in the second crop; and in a greater yield in the third crop. Lettuce cultivated on ruzi grass straw in no-tillage management results in a greater sustainability, in comparison with conventional tillage, in three successive plantings.
The objective of this study was to identify nursing students' knowledge about long-term bladder catheterization. This is a descriptive, cross-sectional research with a quantitative approach. An instrument with multiple choice questions was applied to graduates of a university in the interior of São Paulo. The sample consisted of 81 students from the seventh term, most of them female, 20 to 30 years old, night students, singles, family income of 1 to 4 minimum salaries, no training and no experience in the area of nursing. The questions that presented the highest percentage of correct answers were the materials needed for the procedure (93.8%), a step that is not part of the end of the technique (87.7%) and part of the catheterization process (76.5%). It is concluded that most of the students have knowledge about the technique, since in most of the questions more than 50% of the group pointed out the correct alternative.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
