Background: Patients with nasogastric tube (NTG) nutrition after discharge still need to be transferred to community hospitals for continued care. Effective health education is conducive to raising the level of knowledge of caregivers to promote the rehabilitation of patients.
Methods: Clinical data of 65 caregivers of stroke patients in Putuo Hospital affiliated to Shanghai University of Traditional Chinese Medicine from June 2020 to December 2020 were retrospectively analyzed.
Article Synopsis
- The study examines how alternating drying and wetting impacts soil preferential flow in an arid valley, specifically in the Honghe River area, using methods like dye tracers and image processing.
- Results indicated that this alternation resulted in pronounced matrix flow in the topsoil, increased dye penetration depth, and a higher number of macropores, which in turn enhanced stable effluent rates.
- The findings suggest that the size distribution of macropores shifted due to drying and wetting cycles, making soil more susceptible to preferential flow with a notable correlation between macropore characteristics and flow rates.
To clarify the morphological characteristics of soil preferential flow and the effect of plant roots on its formation, plants from the typical vegetation types of an artificial woodland (Leucaena acacia) and a dry watershed grassland (Heteropogon contortus) of Yuanmou County, Jinsha River were selected as the experimental objects. Based on the staining and tracing method combined with Photoshop CS5 and the Image-Pro Plus 6.0 image processing technology, we analyzed the morphological and distribution characteristics of soil preferential flow under the two planting types and examined the effects of plant roots.
