“海葵”台风路径及其强度分析     

廖廓  蔡晓禾  曾瑾瑜 《闽江学院学报》2013,34(2):128-131

＂海葵＂是在高纬生成的台风,大部分时间活跃在北纬25度以上,在北部副热带高压环流、大陆高压环流引导和自身内力作用下,＂海葵＂台风路径较为稳定,一路沿偏西方向前进.本次过程中,中纬度西风槽和冷空气位置偏北,没有冷空气侵入＂海葵＂台风环流,因此中纬度系统其实不利于＂海葵＂台风生命史的延长.＂海葵＂台风登陆后减弱缓慢,原因之一是没有受到台湾地形的阻挡,另一重要原因是登陆后有源源不断的水汽输送.此外,由于台风登陆前高层由辐合转为辐散,其抽吸作用也有利于台风强度的维持.  相似文献   

A comprehensive update: gastrointestinal microflora,gastric cancer and gastric premalignant condition,and intervention by traditional Chinese medicine     

Yuting LU  Huayi LIU  Kuo YANG  Yijia MAO  Lingkai MENG  Liu YANG  Guangze OUYANG  Wenjie LIU 《Journal of Zhejiang University. Science. B》2022,23(1):1-18

With the recent upsurge of studies in the field of microbiology,we have learned more about the complexity of the gastrointestinal microecosystem.More than 30 genera and 1000 species of gastrointestinal microflora have been found.The structure of the normal microflora is relatively stable,and is in an interdependent and restricted dynamic equilibrium with the body.In recent years,studies have shown that there is a potential relationship between gastrointestinal microflora imbalance and gastric cancer(GC)and precancerous lesions.So,restoring the balance of gastrointestinal microflora is of great significance.Moreover,intervention in gastric premalignant condition(GPC),also known as precancerous lesion of gastric cancer(PLGC),has been the focus of current clinical studies.The holistic view of traditional Chinese medicine(TCM)is consistent with the microecology concept,and oral TCM can play a two-way regulatory role directly with the microflora in the digestive tract,restoring the homeostasis of gastrointestinal microflora to prevent canceration.However,large gaps in knowledge remain to be addressed.This review aims to provide new ideas and a reference for clinical practice.  相似文献   

Effects of an acute bout of exercise on serum soluble leptin receptor (sOB-R) levels

Abstract

We investigated the effects of an acute bout of exercise on serum soluble leptin receptor (sOB-R) concentrations. Eighteen male participants completed two different exercise sessions with intensities of 25% and 65% maximal aerobic capacity (VO₂max). In addition to the energy expenditure during exercise sessions being measured, blood samples were collected before exercise, and immediately, at 24 h, and at 48 h post-exercise to analyse sOB-R, leptin and insulin levels. At 24 h post-exercise, sOB-R and leptin concentrations at the 65% VO₂max were significantly different from those at the 25% VO₂max. Leptin levels at 48 h post-exercise were also significantly lower for the 65% VO₂max than for the 25% VO₂max (P < 0.01). In the 65% VO₂max session, the energy expenditure during exercise was significantly associated with leptin concentrations at 24 h and 48 h and sOB-R concentrations at 24 h post-exercise. However, no correlations were found between sOB-R and leptin at the three post-exercise time points. In conclusion, an acute bout of exercise with 920 kcal of output resulted in an increase in sOB-R levels at 24 h post-exercise. However, the changes in sOB-R levels due to an acute bout of exercise might not contribute to the delayed decrease observed for leptin.  相似文献

An Exploratory Study of Minority Students’ Technology Usage and Perceptions of Technology: Nontraditional Adult Students in Technology-Based Environments     

Yu-Chun Kuo 《Journal of Research on Technology in Education》2018,50(4):350-364

Abstract

The study examines nontraditional, African-American adult students’ use of technologies and their perceptions toward this in technology-based environments. Technology perceptions included computer self-efficacy, Internet self-efficacy, user attitude, and computer anxiety. The effects of student characteristics on these factors and the relationships between these factors were examined throughout this study. Participants included minority students who participated in face-to-face or online undergraduate courses offered in continuing education. A quantitative approach was undertaken to analyze the collected data. Results indicated that nontraditional minority students utilized basic software tools more frequently than the advanced ones, suggesting that many of them may lack the knowledge or skills for advanced technologies. Age, hours spent online, and previous online course experiences influenced students’ technology perceptions. Gender did not have an impact on technology perceptions. Internet self-efficacy was affected by most of the student characteristics variables. Computer self-efficacy was found to be a good predictor for both user attitude and computer anxiety. (Keywords: technology usage, technology perceptions, student characteristics, computer and Internet self-efficacy, minority students)  相似文献   

Probing primordial gravitational waves: Ali CMB Polarization Telescope     

Hong Li  Si-Yu Li  Yang Liu  Yong-Ping Li  Yifu Cai  Mingzhe Li  Gong-Bo Zhao  Cong-Zhan Liu  Zheng-Wei Li  He Xu  Di Wu  Yong-Jie Zhang  Zu-Hui Fan  Yong-Qiang Yao  Chao-Lin Kuo  Fang-Jun Lu  Xinmin Zhang 《国家科学评论(英文版)》2019,6(1):145

In this paper, we will give a general introduction to the Ali CMB Polarization Telescope (AliCPT) project, which is a Sino–US joint project led by the Institute of High Energy Physics and involves many different institutes in China. It is the first ground-based Cosmic Microwave Background (CMB) polarization experiment in China and an integral part of China''s Gravitational-wave Program. The main scientific goal of the AliCPT project is to probe the primordial gravitational waves (PGWs) originating from the very early Universe. The AliCPT project includes two stages. The first stage, referred to as AliCPT-1, is to build a telescope in the Ali region of Tibet at an altitude of 5250 meters. Once completed, it will be the highest ground-based CMB observatory in the world and will open a new window for probing PGWs in the northern hemisphere. The AliCPT-1 telescope is designed to have about 7000 transition-edge sensor detectors at 95 GHz and 150 GHz. The second stage is to have a more sensitive telescope (AliCPT-2) with more than 20 000 detectors. Our simulations show that AliCPT will improve the current constraint on the tensor-to-scalar ratio r by one order of magnitude with three years'' observation. Besides the PGWs, AliCPT will also enable a precise measurement of the CMB rotation angle and provide a precise test of the CPT symmetry. We show that three years'' observation will improve the current limit by two orders of magnitude.  相似文献   

Indigenous Crisis Counseling in Taiwan: An Exploratory Qualitative Case Study of an Expert Therapist     

Ben C. H. Kuo  Wei-Su Hsu  Nien-Hwa Lai 《International journal for the advancement of counseling》2011,33(1):1-21

In this study, we adopted a single qualitative case study method to explore and examine indigenous approaches to crisis counseling in Taiwan, through the distinct lens of an expert Taiwanese counseling psychologist. In-depth, open-ended interviews were conducted with the psychologist (as the case) to document her lived clinical experiences counseling a grief-stricken Taiwanese family in crisis (as the context). Using open-code data analysis, five cultural themes were abstracted from the interviews: a) significance of counselor’s authority and expertness; b) primacy of client-counselor rapport and relationship; c) centrality of collective familism; d) observance of indigenous grief response and process; and e) adherence to face-saving communication and interpersonal patterns. Implications for implementing crisis counseling practice and research with native Taiwanese/Chinese clients based on these preliminary findings are discussed.  相似文献
