Temperature (T),PH,light intensity (I),dissolved oxygen (DO) and filling rate five factors plays important role in the process of ammonia nitrogen removal ,related data between ammonia removal and five factors was received through multi-factor orthogonal test,and established relations model between the five factor and nitrogen removal. The results show that five-factors had significant effect on AR,and the best combinations for removing AR was temperature 30 ℃,pH=7.0,light intensity 6 000 lux,dissolved oxygen 5.0 mg/L and the fill rate 10%. According to the experimental data,equation model was proposed and coefficient of determination R2 =0.864 8,P<0.05. Samples T-test was done between the model predictions and the actual measured values.Test results showed that the significant difference of overall mean value sig. (2-tailed) was 0.978 (P>0.05),it Shows that had no significant difference between model predictions and the actual measured value,and model had a high degree of fitting.展开更多

The Luoyixi section near Luoyixi town, Guzhang, northwestern Hunan is ratified as the boundary stratotype for the base of the global Guzhangian Stage, which is the upmost stage of an unnamed series termed provisionally as Cambrian Series 3. The GSSP position lies 121.3 m above the base of the Huaqiao Formation in the section, coinciding with the first appearance of the cosmopolitan agnostoid trilobite Lejopyge leavigata.The Duibian B section at Duibian village, Jiangshan, western Zhejiang, is proposed as the boundary stratotype for the base of the proposed global Jiangshanian Stage that is the second stage of the Furongian Series. The proposed GSSP position lies 108.12 m above the base of the Huayansi Formation in the section, coinciding with the first appearance of the cosmopolitan agnostoid trilobite Agnostotes orientalius. This horizon is also with the first appearance of the cosmopolitan polymerid trilobite lrvingella angustilimbata.展开更多

Methods A phenomenological-qualitative,non-experimental type of research was utilized to recruit 27 staff nurses/clinical teachers in China. Data was collected by using audio-tapes and taking notes in the interviews. Results A content analysis was conducted and the sorted into four themes:(1) The things that they were able to teach their students;(2) The things that they were not able to teach their students;(3) The difficulties encountered in doing Clinical Teaching for their students;(4) Suggestions to improve Clinical Teaching. Conclusion According to the findings,the "CP's Proposed Nursing Clinical Teaching Model"should be introduced into the clinical set-up for staff nurses/clinical teachers handling nursing students in China.展开更多

Consequently, many protocols and algorithms for hospitalized patients with COVID-19 induced hyperglycemia based mainly on recent studies and previous evidence on non-COVID-19 patients were published. Of note nearly all guidelines released by the different COVID-19 committees in Libya don’t include a clear focus on management of in-patient hyperglycemia and maybe this plays a pivotal role in increase our COVID-19 in-hospital mortality. I proposed a simplified approach depending on the released international guidelines to be easily implemented by Libyan health care staff caring about COVID-19 patients and hoping to be accepted by our National Diabetes Committee.展开更多

In order to keep abreast with the advanced international level in terms of scholarship, a well-known Chinese scientist has called on the central authorities to set up a national biomedical information center.

A nonlinear oscillation, the solar cycle must be generated internally, and Babcock-Leighton models apply an artificial nonlinear source term that can simulate the observations—which leaves open the question of the actual source mechanism for the solar cycle. Addressing this question, we propose to take guidance from the wave mechanism that generates the 2-year Quasi-biennial Oscillation (QBO) in the Earth atmosphere. Upward propagating gravity waves, eastward and westward, deposit momentum to generate the observed zonal wind oscillation. On the Sun, helioseismology has provided a thorough understanding of the acoustic p-waves, which propagate down into the convective envelope guided by the increasing temperature and related propagation velocity. Near the tachocline with low turbulent viscosity, the waves propagating eastward and westward can produce an axisymmetric 22-year oscillation of the zonal flow velocities that can generate the magnetic solar dynamo. Following the Earth model, waves in opposite directions can generate in the Sun wind and magnetic field oscillations in opposite directions, the proposition of a potential solar cycle mechanism.展开更多

WM was slowly introduced into China by missionaries from the middle 17th century to the beginning of the 19th century. By 1840, WM began to take root in China. Western hospitals, clinics, medical schools and nursing schools spread rapidly throughout the country. At that time, with the might and power portrayed by Western countries,展开更多
