Totally 3 QTLs forSPAD values, two on chromosome 3 located at interval RG179-CDO337 and RG348-RZ329, respectively, andone on chromosome 10 at interval RZ500-RG134, were detected under stressed conditions of low N inthe soil and/or nutrient solution culture experiments. One QTL located at interval RG179-GDO337 onchromosome 3 associated with a relative change in SPAD value from a high N level to a low N level inthe soil culture experiment was also detected.Based on the different responses to low N stressbetween the two parents, it was supposed that the QTLs identified in this study associated withnitrogen efficiency in rice at low N levels might be useful in applying marker technology to ricebreeding programs.展开更多

The deposition rate was about 0.11 nm/s. The as-deposited films were annealed at 450,550, and 650℃, respectively, in a vacuum lower than 3 x 10~3 Pa for 1 h. The Ni_(83)Fe_(17) filmsmainly grow with a crystalline orientation of [111] in the direction of the film growth. With theannealing temperature increasing, the [111] orientation enhances. For films deposited at all fourdifferent temperatures, the significant improvement on anisotropic magnetoresistance occurs at theannealing temperature higher than 550℃. But for films deposited at ambient temperatures and 240 ℃,the anisotropic magnetoresistance can only rise to about 1% after 650 ℃ annealing. For filmsdeposited at 350℃ and 410℃, the anisotropic magnetoresistance rises to about 3.8% after 650℃annealing. The atomic force microscopy (AFM) observation shows a significant increase in grain sizeof the film deposited at 350℃ after 650℃ annealing. The decrease in resistivity and the increasein anisotropic magnetoresistance are caused by the decrease in point defects, the increase in grainsize, and the improvement in lattice structure integrity of the films.展开更多

Methods: 80 cases of hepatobiliary surgery patients in our hospital from May 2020 to October 2021 were selected as research objects, and were divided into observation group and control group according to the random number table method. 42 cases in the observation group received comfortable nursing intervention and 38 cases in the control group. According to the relevant standards and criteria, a reasonable distinction can be made. Results: after nursing, the practical operation indexes of the observation group were significantly better than those of the control group, and the difference was statistically significant (P<0.05). After nursing, the SAS score, SDS score, pain level score and incidence rate of disease in the observation group were significantly lower than those in the control group, and the difference was statistically significant (P<0.05). The quality of life score of the observation group was higher than that of the control group, and the satisfaction rate of the observation group was significantly higher than that of the control group (P<0.05). Conclusion: comfortable nursing for patients with hepatobiliary surgery can effectively improve the index value of surgical treatment, reduce anxiety and depression, reduce the incidence of diseases, relieve pain, improve the curative effect and results, and make patients satisfied, which is very worthy of reference.展开更多
