Effects of Ecological Restoration of Mangrove Wetlands Using Native Mangrove Species to Replace Spartina alterniflora: A Case Study in Southern China

引用

Open Journal of Ecology 2023年第12期13卷 956-976页

作者： Jiaming Li Mouxin Ye Chunxi Cao Shozo shibata Graduate School of Global Environmental Studies Kyoto University Kyoto Japan Shenzhen Mangrove Wetlands Conservation Foundation Shenzhen China

Within the expanse of China’s coastline, the invasive alien cordgrass species Spartina alterniflora has caused profound nationwide damage and has emerged as a critical factor contributing to the degradation of mangrove wetlands, especially in the study area in Beihai, Guangxi. However, current treatments for S. alterniflora remain less effective and limited research focuses on the preliminary changes after artificial plantation. A comprehensive approach combining physical interventions with biological control measures has been employed to eradicate smooth cordgrass and facilitate the restoration of native mangrove wetlands. The study involved the periodic monitoring of the growth conditions of mangroves and the biodiversity of avian and benthic organisms, conducted at three to four-month intervals following the artificial plantation with one-year-old seedlings and propagules of native mangrove species Rhizophora stylosa. Results indicated that through the allometric equation, the above-ground biomass of planted seedlings had a ~20 g increase in average but the growth conditions were not significant over an eight-month period. High percentage of important avian species underlined the potential of the study site to serve as a worthwhile habitat and notable seasonal variations were observed in the biodiversity of bird species. Biodiversity indices of bird and benthos species also followed a similar fluctuation and reached a peak in April 2023. This research underscores the initial lack of distinct improvements during the early stages of the ecological restoration project, thorough maintenance, long-term monitoring, holistic considerations on a larger scale would be imperative for ongoing projects in the future.

Numerical and Experimental Investigation on Heat PropagationThrough Composite Sinter Bed With Non-Uniform Voidage:Part Ⅱ Prediction of Process Efficiency

引用

Journal of Iron and Steel Research(International) 2010年第10期17卷 1-6页

作者： Sergey V Komarov Hiroyuki shibata Naohito Hayashi Eiki Kasai Nippon Light Metal Company Tohoku University

The results of numerical simulation of the mosaic embedding iron ore sintering （MEBIOS） process according to the model presented in the first part of the study are introduced. The main objective of the second part is the elucidation of key factors influencing the process efficiency, particularly the sintering completeness, velocity of the heat wave propagation and maximum temperature achievable in the pellet during the wave propagation. Numerical results reveal that the mass fraction of coal, diameter of coal particles and air inlet velocity are of prime importance in determining efficiency of the MEBIOS sintering process.

Activation of Trifluoromethylthio Moiety by Appending Iodonium Ylide under Copper Catalysis for Electrophilic Trifluoromethylation Reaction

引用

Chinese Journal of Chemistry 2016年第5期34卷 485-489页

作者： Ibrayim Saidalimu Shugo Suzuki Etsuko Tokunaga Norio shibata Department of Frontier Materials Nagoya Institute of Technology Gokiso Showa-ku Nagoya 466-8555 Japan Department of Nanopharmaceutical Sciences Nagoya Institute oF Technology Gokiso Showa-ku Nagoya 466-8555 Japan

A novel iodonium-ylide compound 2 that appends a trifluoromethylthio （SCF3） group is disclosed as a new, shelf-stable electrophilic trifluoromethylation reagent. Unlike known shelf-stable electrophilic trifluoromethylation reagents, 2 has a stable SCF3 group which is activated by appending iodonium ylide under copper catalysis via sul- fonium ylide to generate a cationic trifluoromethyl （CF3） species. Reagent 2 was found to be an efficient electro- philic trifluoromethylation reagent for a wide range of silyl enol ethers 3 under copper catalysis. Cyclic and acyclic a-trifiuoromethyl ketones 4 were obtained by reagent 2 in moderate to good yields. On the other hand, a difluoro- methylthio analogue 5 did not affect intermolecular transfer difluoromethylation to substrates. Instead, intramolecu- lar 1,4-migration proceeded similar to the Stevens rearrangement to provide 6 in 21% yield, independent of the presence of nucleophiles 3.

Open Journal of Therapy and Rehabilitation 2022年第1期10卷 1-8页

作者： Hiroya Miyabara Seigo Koura Moemi Matsuo Makoto Uchinoura Yuki Kishikawa Yuji Yamaguchi Youhei Komatsu Seijiro Nishimura Shinichi shibata Hajime shibata Faculty of Rehabilitation Nishikyusyu University Kanzaki Japan Kurume Rehabilitation Hospital Kurume Japan

Purpose: To compare and examine motor and cognitive functions in people who require support, and in healthy elders. Method: The variables of age, BMI, educational background, blood pressure, grip strength, knee extension, gait speed, MMSE, and subjective health feeling for 36 rehabilitation users and 22 healthy elders were assessed. We compared and examined motor and cognitive functions in rehabilitation users who need support and healthy elders. Results: The percentage of MMSE scores with 27 points or higher and that of subjective health feeling with 3 points or higher were significantly higher in healthy elders than in rehabilitation users. Systolic and diastolic blood pressure were significantly higher in rehabilitation users than in healthy elders. Gait speed and MMSE scores were significantly higher in healthy elders than rehabilitation users. Conclusion: Gait speed could be used for physical fitness in elders. Gait speed was the best physical fitness measurement for elders. Gait speed of rehabilitation users was strongly related to MMSE scores. Gait speed could be a determinant of MMSE scores.

引用

Open Journal of Therapy and Rehabilitation 2022年第2期10卷 54-61页

[Purpose] This study aimed to evaluation of the Tokyo cognitive assessment (Toca) for predicting cognitive impairment in rehabilitation users. [Method] The variables of age, BMI, educational background, Toca for 36 rehabilitation users and 22 healthy elder were assessed. We compared cognitive functions in rehabilitation users who need support and healthy elders. [Results] Of the Toca 1 to 11 trials, there was a significant difference other than 9, 10 rials. The Toca scores with 8 points higher were significantly higher in healthy elders than in rehabilitation users. The area under the receiver-operator curve (AUC) for predicting mild cognitive impairment (MCI) by the Toca was 0.874. Using a cut-off point of 19/20, the Toca demonstrated a sensitivity of 83.9% and a sensitivity of 85.0% in diagnosing MCI. [Conclusion] The Toca is a brief cognitive screening tool with high sensitivity and specificity for detecting MCI as currently conceptualized in rehabilitation users.
