Abstract: The objective of this work is to propose a chemical management alternative to control Bidens pilosa and Euphorbia heterophylla in genetically modified soybean without affecting grain production and seed germination by using glyphosate applied only once and in mixture, aiming to reduce the number of applications and the amount of herbicides used. The experimental design was randomized blocks with 10 treatments and 4 replications. The soybean used was BRS-Valiosa RR. The treatments consisted of glyphosate and chlorimuron-ethyl applied once and alone (1.5; 2.0 and 80 L or g ha-1 pc), glyphosate in mixture with chlorimuron-ethyl (1.5+10 and 2.0+10 L or g ha-1 pc) and sequentially applied glyphosate (1.5/1.5; 2.0/1.5 and 2.0/1.5/1.5 L ha-1 pc), plus weeded (clean) and non-weeded (dirty) witnesses. The evaluations were: herbicide efficacy in B. pilosa and E. heterophylla, phytotoxicity, density, height and grain yield (kg ha-1) in soybean. The production data obtained were subjected to analysis of variance and F test by the SANEST program (P<0.05). It was concluded that the studied species, B. pilosa and E. heterophylla, were controlled by glyphosate at levels above 90%. There was no visual injury in soybean and no significant decrease in production and germination.

Abstract: To quantitatively analyse conditions of intensive care experiences and influencing factors of patients. A database was established, it can be seen from the overall experience index that in the SD dimensionality, 46.11% patients have highly bad experiences and 86.11% patients have moderate and highly bad experiences in total plus the patients with moderate scores; in ET dimensionality, 32.78% patients have highly bad experiences and 67.22% patients have moderate and highly bad experiences in total plus the patients with moderate scores; in TII dimensionality, 73.88% patients have moderate and highly bad experiences. LICU and LMV of patients and overall GEI and various factor scores exhibit a significant positive correlation (P<0.05) indicating that the longer the time of mechanical ventilation treatment and length of stay in ICU, the more bad experiences the patients will have; patients' APACHE scores and the overall GEI, dimensionality ET, ACF and TII exhibit a positive correlation (P<0.05) indicating the severer the disease is, the more bad experiences on intensive care the patient will have. Mechanical ventilation duration, disease severity degrees, marital status and age are the major factors influencing intensive care experiences of patients in mechanical ventilation.
