CARDAMOM 2001-2010 global carbon Model-Data Fusion (MDF) analysis
No full textThe CARbon DAta MOdel fraMework (CARDAMOM; Bloom et al., 2015 in review) outputs are derived from a global 1-degree x 1-degree 2001-2010 model-data fusion (MDF) analysis. The datasets include allocation fractions (AF) residence times (RT), mean carbon pool stocks (CP) and fluxes (FL). A list of files and their contents is provided below.
The Data Assimilation Linked Ecosystem Carbon model version 2 (DALEC2) and the Markov Chain Monte Carlo MDF algorithm are described by Bloom & Williams (2015); the fire module is described by Bloom et al., (2015; in review). Data constraints used in the CARDAMOM analysis consist of MODIS leaf area index (LAI), Harmonised World Soil Database (HWSD; Hiederer & Kochy, 2012) and tropical biomass (Saatchi et al., 2011). For each 1-degree x 1-degree gridcell, the metrics (e.g. mean, median, etc.) are based on 4000 DALEC2 model parameter samples unique to that grid-cell.
We note that the full 2001-2010 CARDAMOM output amounts to roughly 10 TB in binary format. For the sake of brevity, we have limited the following datasets to the subset presented in Bloom et al., (2015, in review). Additional MDF outputs can be made available upon request.

COMPARISON OF ANTI-ACETYLCHOLINESTERASE ACTIVITY OF BULB AND LEAF EXTRACTS OF STERNBERGIA CANDIDA MATHEW & T. BAYTOP
No full textStudies on Alzheimer's disease have been highlighted due to increasing prevalence of this disease. Oldest hypothesis about the pathophysiology strengthens the research of cholinesterase inhibitors for treatment. Amaryllidaceae plants are well known for alkaloids showing cholinesterase inhibiting activity. Among them, Sternbergia species gained attention as a source of metabolites of these alkaloid contents. Studies have focused mainly on the bulbs of these plants. In this study the potential acetylcholinesterase (AChE) inhibitory activity of endemic Sternbergia candida Mathew & T. Baytop (Sc) species was evaluated in both bulbs and leaves in comparison with lycorine. We report for the first time that methanol and chloroform leaf extracts of the plant show AChE inhibitory (AChEI) activity. Among the leaf extracts methanolic extract was much more potent than chloroform extract by means of AChE inhibition. Although IC50 values for methanolic extract was found to be lower than reference drug lycorine; this value of inhibition did not reach to a statistically significant level. Future studies aiming at investigation of the AChE inhibitory activity could be considered using leaves of the plant.Ernst Mach Grants; OEADThe authors are thankful to Ernst Mach Grants and OEAD for the supports; Prof. Dr. Ulvi Zeybek and Prof. Dr. Levent Ustunes for facilities; Dr. Bio.

Prescribing by mental health nurses: the UK perspective
No full textPURPOSE. This article aims to discuss the growth of mental health nurse (MHN) prescribing in the United Kingdom as an exemplar for readers to compare progress in their own countries and context. This study also aims to provide a historical overview of this process in the United Kingdom where MHNs prescribe safely and competently.
CONCLUSIONS. Finally, evidence has shown that MHNs with prescriptive authority are competent when prescribing when compared to psychiatrists.
PRACTICE IMPLICATIONS. Despite organizational barriers and educational concerns, MHN prescribing is becoming embedded in the healthcare context in the United Kingdo
Consultation skills and decision making
No full textConsultation and decision making form a central and critical part of non-medical prescribing practice. This chapter introduces the reader to key consultation and decision-making models which can be used to help practitioners guide their development in this area. The importance of communication and consideration of the patient’s health beliefs will be discussed. Some of the evidence related to consultation by different non-medical prescribing professions will be explored. Frameworks supporting good prescribing will be discussed as well as influences on prescribing
Modular RT-Motion USB Software Framework
No full textPhilips Applied Technologies has developed the RT-Motion USB platform as a compact distributed real-time motion control platform, but the platform can still be improved by developing a more advanced software framework. The goal of this thesis project is to design a modular software framework to complement the RT-Motion USB platform with extendability, flexibility, and configurability. The design focuses on the extendability of the platform by developing foundation building blocks to integrate software extension modules and device drivers easily. The design emphasizes the principle of simplicity to ensure the lowest possible overhead and highest reliability. The firmware is modular, which allows each module to concentrate on its own area. The implementation of the design has been tested and is proved to provide extendability, flexibility, and configurability while incurring low overhead. The improvement to the RT-Motion USB platform is expected to extend the applicability of the RT-Motion USB platform to a broader application range.Microelectronics & Computer EngineeringElectrical Engineering, Mathematics and Computer Scienc
Exploring the effects od a rigid body on the evolution of the Rayleigh-Taylor instability
No full textThis talk discusses the effects of a rigid solid boundary impeding the evolution of the Rayleigh-Taylor (RT) instability. The introduction of an obstacle completely alters the evolution of RT growth, instead of mixing the domain rapidly, a quasi-steady flow, rich in dynamics is established for long periods of time. Using a combination of low Atwood number experiments and ILES simulations, this talk will present a non-dimensional analytical model for a multi-stage mixing process, discussing the effects of the opening size and topology on the density change of each layer, buoyancy driven flux through the opening and mixing efficiency
Small-Scale Properties of Two-Dimensional Rayleigh-Taylor Turbulence
No full textWe report a high-resolution numerical study of small-scale properties of two-dimensional (2D) miscible Rayleigh-Taylor (RT) incompressible turbulence with the Boussinesq approximation at small Atwood number and unit Prandtl number. Our results show that the buoyancy force balances the inertial force at all scales below the integral length scale and thus validate the basic force-balance assumption of the Bolgiano-Obukhov scenario in 2D RT turbulence. We further examine other small-scale properties of 2D RT turbulence, such as temporal evolution of energy and thermal dissipation rates, the emergence of intermittency and anomalous scaling for high order moments of velocity and temperature differences, distributions of local dissipation scales, and so on
ナイジェリア南東部および中南部におけるラッサウイルス検出のためのRT-LAMPアッセイの開発
No full textLassa virus (LASV) causes Lassa fever (LF), a viral hemorrhagic fever endemic in West Africa. LASV strains are clustered into six lineages according to their geographic location. To confirm a diagnosis of LF, a laboratory test is required. Here, a reverse transcription loop-mediated isothermal amplification (RT-LAMP) assay using a portable device for the detection of LASV in southeast and south-central Nigeria using three primer sets specific for strains clustered in lineage II was developed. The assay detected in vitro transcribed LASV RNAs within 23 min and was further evaluated for detection in 73 plasma collected from suspected LF patients admitted into two health settings in southern Nigeria. The clinical evaluation using the conventional RT-PCR as the reference test revealed a sensitivity of 50% in general with 100% for samples with a viral titer of 9500 genome equivalent copies (geq)/mL and higher. The detection limit was estimated to be 4214 geq/mL. The assay showed 98% specificity with no cross-reactivity to other viruses which cause similar symptoms. These results suggest that this RT-LAMP assay is a useful molecular diagnostic test for LF during the acute phase, contributing to early patient management, while using a convenient device for field deployment and in resource-poor settings.長崎大学学位論文 学位記番号:博(医歯薬)甲第1265号 学位授与年月日:令和2年9月18日Author: Christelle M.

The relationship between co-authorship, currency of references and author self-citations
No full textThis paper attempts to identify the relationship between co-authorship and the currency of the references and author self-citations in the key journals of environmental engineering. The results show that the self-citation rate of co-authored articles is higher than in single-authored articles. A statistically significant correlation is identified between the numbers of co-authors, the rate of author self-citing and the author self-cited; though it was a low correlation. The value of coefficient correlation between the number of co-authors and the author self-citing rate is slightly higher than that between the number of co-authors and the author self-cited rate, which indicates that the number of co-authors hold a stronger correlation with the self-citing rate than the self-cited rate. Meanwhile, self-citing references are found to be more up-to-date than references to others. The range of publication years of self-citing references is smaller than that of references to others, indicating that researchers tend to preferentially cite their own recent works. There is no significant difference in the latest references between self-citing references and the references to others. It might result from electronic journals that provide an easy access to the most current publications.補正完畢國外SSCIY紙本電子版HU
