Investigation on Damage Regularity of Mikania micrantha

[Objectives]The paper was to understand the occurrence and damage regularity of the invasive plant Mikania micrantha in Huadu District of Guangzhou.[Methods]The damage status of M.micranthFa in different forest lands and its annual growth dynamics were investigated by field investigation.[Results]With the change of canopy density from low to high,the occurrence degree of M.micrantha changed from high to low.The occurrence degree of M.micrantha in different forest land types was:abandoned orchard>wasteland>roadside greenbelt>waterside>forest edge>normally managed orchard.[Conclusions]M.micrantha enters the rapid growth period from March to May in spring,with the growth rate gradually slowing down after June.The result provides a theoretical basis and practical guidance for the prevention and control of M.micrantha.

Development Path for Rural Tourism of Henan Province from the Perspective of Innovation

According to innovation theory and research on innovation of rural tourism development,innovation theory is of great guiding significance for rural tourism development of Henan Province. At present,rural tourism development in Henan Province has made outstanding achievements,but there are still problems: innovation concept of rural tourism is not scientific; product lacks consolidation,industrial chain is not perfect,and public service level of tourism is relatively low. In order to realize optimization and upgrade of rural tourism in Henan Province,it is recommended to make innovation of development path and take development paths such as innovation of development concept,product innovation,industrial structure innovation of rural tourism,and public service innovation for rural tourism.

The Effect and Effectiveness Evaluation of Sit-up Training on Elderly Bedridden Patients with Severe Pneumonia

The objective of the study was to access the effect and the effectiveness of sit-up training on elderly bedridden patients with severe pneumonia.A total of 150 elderly bedridden patients diagnosed with severe pneumonia were recruited for this study.They were divided equally into the observation group and control group,that is,75 cases in each group.All patients were selected from January 2016 to April 2018.On this basis,both groups were treated with the same routine nursing care except with the addition of 30–60 min situp trainings twice daily for the control group under supervision.The clinical hospitalization outcomes,length of hospital stay,and patient care satisfaction of the two groups were compared.The clinical hospitalization outcomes,length of hospital stay,and patient satisfaction of the observation group were found to be superior to the control group,and the difference was significant.In bedridden elderly patients with severe pneumonia,sit-up training had positive effects and beneficial in improving the clinical outcomes and recovery rate.

An organic-inorganic hybrid thermochromic ferroelastic with multi-channel switches

Multifunctional switchable materials are attracting tremendous interest because of their great application potential in signal processing,information encryption,and smart devices.Here,we reported an organic-inorganic hybrid thermochromic ferroelastic crystal,[TMIm][CuCl_(4)](TMIm=1,1,3,3-tetramethylimidazolidinium),which undergoes two reversible phase transitions at 333 K and 419 K,respectively.Intriguingly,these three phases experience a remarkable ferroelastic-paraelastic-ferroelastic(2/m-mmm-2/m)transition,which remains relatively unexplored in ferroelastics.Moreover,the ferroelastic domains can be simultaneously switched under temperature and stress stimuli.Meanwhile,[TMIm][CuCl_(4)]exhibits thermochromic phenomenon,endowing it with extra spectral encryption possibilities during information processing.Combined with dielectric switching behavior,[TMIm][Cu Cl_(4)]are promising for practical applications in memory devices,next-generation sensors,and encryption technology.
