Vetiver Grass and Micropollutant Leaching Through Structured Soil Columns Under Outdoor Conditions

Pedosphere 2016年第4期26卷 522-532页

作者： Sylvie DOUSSET Norbert ondo ZUE ABAGA David BILLET Universite de Lorraine-CNRS-Laboratoire Interdisciplinaire des Environnements Continentaux (LIEC) 56506 Vandoceuvre-les-Nancy

In Burkina Faso, significant amounts of endosulfan are applied to cotton fields; in addition, urban vegetable agriculture is often characterised by high fertiliser inputs, such as urban solid wastes containing heavy metals(e.g., Cu and Cd). Thus, the relevance of surrounding cotton and urban vegetable plots with vetiver(Vetiveria zizanioides) hedges to reduce environmental pollution by micropollutants was investigated using a leaching experiment, with outdoor lysimeters filled with two representative agricultural soils of Burkina Faso: Vertisol and Lixisol. After 6 months, little Cu was found in the leachates(remain at the soil surface. Despite leachate and bromide recoveries being greater in soils planted with vetiver grass than in the bare soils, smaller amounts of endosulfan and Cd were found in the effluents from the planted soils(0.01% to 0.70% of the applied amount) than in those from the bare soils(0.01% to 1.48% of the applied amount), in agreement with their adsorption coefficients. These results may also be explained by a greater degradation of endosulfan in planted soils compared to bare soils and the absorption of Cd by vetiver. Thus, vetiver may decrease the risk of groundwater contamination,especially for Cd and endosulfan, which are more mobile than Cu. In addition, despite the smaller amounts of endosulfan and Cd measured in the Vertisol leachates(0.01% and 0.04% of the applied amount, respectively) compared to the Lixisol leachates, vetiver was more effective in decreasing the leaching of micropollutants if planted on Lixisol rather than on Vertisol. Further field monitoring is necessary to demonstrate the effectiveness of vetiver under the climatic conditions of Burkina Faso.

Optogenetics and its application in neural degeneration and regeneration

引用

Neural regeneration research 2017年第8期12卷 1197-1209页

作者： josue D.Ordaz Wei Wu Xiao-Ming Xu Spinal Cord and Brain Injury research Group Stark Neurosciences Research InstituteIndiana University School of MedicineIndianapolisINUSA Department of Neurological Surgery Indiana University School of MedicineIndianapolisINUSA Goodman Campbell Brain and Spine IndianapolisIndianaUSA Department of Anatomy and Cell Biology Indiana University School of MedicineIndianapolisINUSA

Neural degeneration and regeneration are important topics in neurological diseases. There are limited options for therapeutic interventions in neurological diseases that provide simultaneous spatial and temporal control of neurons. This drawback increases side effects due to non-specific targeting. Optogenetics is a technology that allows precise spatial and temporal control of cells. Therefore, this technique has high potential as a therapeutic strategy for neurological diseases. Even though the application of optogenetics in understanding brain functional organization and complex behaviour states have been elaborated, reviews of its therapeutic potential especially in neurodegeneration and regeneration are still limited. This short review presents representative work in optogenetics in disease models such as spinal cord injury, multiple sclerosis, epilepsy, Alzheimer＇s disease and Parkinson＇s disease. It is aimed to provide a broader perspective on optogenetic therapeutic potential in neurodegeneration and neural regeneration.

A unified analysis of a micro-beam,droplet and CNT ring adhered on a substrate:Calculation of variation with movable boundaries

引用

Acta Mechanica Sinica 2013年第1期29卷 62-72页

作者： Jian-Lin Liu re Xia School of Pipeline and Civil Engineering China University of Petroleum School of Power and Mechanical Engineering Wuhan University

In this study, we developed a general method to analytically tackle a kind of movable boundary problem from the viewpoint of energy variation. Having grouped the adhesion of a micro-beam, droplet and carbon nanotube （CNT） ring on a substrate into one framework, we used the developed line of reasoning to investigate the adhesion behaviors of these systems. Based upon the derived governing equations and transversality conditions, explicit solutions involving the critical parameters and morphologies for the three systems are successfully obtained, and then the parameter analogies and common characteristics of them are thor- oughly investigated. The presented method has been verified via the concept of energy release rate in fracture mechanics. Our analyses provide a new approach for exploring the mechanism of different systems with similarities as well as for understanding the unity of nature. The analysis results may be beneficial for the design of nano-structured materi- als, and hold potential for enhancing their mechanical, chemical, optical and electronic properties.

Since the initial description, the name Musa dasycarpa Kurz (1867) has been unclear to most botanists. It has usually been synonymized with M. velutina H. Wendl. & Drude (1875). However, although the original diagnosis was very short, 'fruits hairy', it is adequate. Thus, according to Vienna Codes, M. dasycarpa Kurz has priority over M. velutina H. Wendl. & Drude. The aim of this study is to settle the true identity and to update the description of M. dasycarpa Kurz. For that purpose the names M. dasycarpa and M. velutina are typified. In addi-tion, critical notes regarding M. assamica Bull. are given; it is neotypified here, and considered as conspecific with M. sanguinea Hook. f.

Transcultural Validation and Adaptation of the Academic Stress Questionnaire (CEA) in Students of Puerto Rico

引用

Open Journal of Nursing 2024年第10期14卷 513-529页

作者： josue Pacheco-Castillo Department of Nursing Ana G. Mndez University Gurabo Puerto Rico

Background: There are multiple questionnaires to measure academic stress in university students, which have been used in nursing students. In Puerto Rico, a questionnaire valid in content and reliability was required to measure the variable of academic stress in nursing students. Purpose: The aim of this study was to adapt transculturally and validate the Academic Stress Questionnaire (CEA) for its use in Puerto Rico. Materials and Methods: Used for the first phase of this study consisted in the evaluation of the validity of content and appearance, whereas the second phase was the actual administering of the questionnaire to 20 (twenty) nursing students, to pilot test its internal consistency using the Cronbach’s α test. results: Validity of content and appearance allowed for the modification of the questionnaire into one, consisting of 42 items, thus eliminating 34 premises from the original 76 items the questionnaire was composed of. Furthermore, the appearance of the questionnaire was modified by placing the measuring scales in columns, adapting social, demographic, and academic data to the required Puerto Rican reality. The sections meant to measure the academic stress variables were left intact, except for the linguistics adaptation, which was accomplished by a team of experts in the Spanish language. With an α global of 0.80 and coefficients larger than 0.7 in the multi-item sub scales, which oscillated between 0.750 and 0.860, the questionnaire provides a high reliability. Conclusion: Although the values reported in this study are somewhat lower than previous research, they were comparable the Cronbach’s Alpha coefficients reported by Cabanach, in which the numbers reported are considered high (α > 0.70) which show acceptable confiability of the subscales included in the study and a high degree of consistency and thus can be relied upon in future research. In synthesis, the Academic Stress Questionnaire (CEA) modified and adapted, thoroughly fulfills the esta

Since the initial description, the name Musa aurantiaca Baker (1893) has been unclear to most botanists. The aim of this study is to settle its true identity and to update the description. The plant is distributed in the regions of Upper Assam and Arunachal Pradesh, India, Northern Myanmar and Tibet, China where it occurs commonly but it is not mentioned in Chinese literature at all. In this paper, the authors also review the description and the literature history of M. aurantiaca from 1893 to the present. Musa aurantiaca Baker is typified here.
