1high-entropy silicide:(Mo_(0.2)Nb_(0.2)Ta_(0.2)Ti_(0.2)W_(0.2))Si_(2)显示文摘A high-entropy metal disilicide,(Mo_(0.2)Nb_(0.2)Ta_(0.2)Ti_(0.2)W_(0.2))Si_(2),has been successfully synthesized.X-ray diffraction(XRD),energy dispersive X-ray spectroscopy(EDX),and electron backscatter diffraction(EBSD)collectively show the formation of a single high-entropy silicide phase.This high-entropy(Mo_(0.2)Nb_(0.2)Ta_(0.2)Ti_(0.2)W_(0.2))Si_(2) possesses a hexagonal C40 crystal structure with ABC stacking sequence and a space group of P6222.This discovery expands the known families of high-entropy materials from metals,oxides,borides,carbides,and nitrides to a silicide,for the first time to our knowledge,as well as demonstrating that a new,non-cubic,crystal structure(with lower symmetry)can be made into highentropy phase.This(Mo_(0.2)Nb_(0.2)Ta_(0.2)Ti_(0.2)W_(0.2))Si_(2) exhibits high nanohardness of 16.7±1.9 GPa and Vickers hardness of 11.6±0.5 GPa.Moreover,it has a low thermal conductivity of 6.9±1.1Wm^(-1) K^(-1),which is approximately one order of magnitude lower than that of the widely-used tetragonal MoSi_(2) and ~1/3 of those reported values for the hexagonal NbSi_(2) and TaSi_(2) with the same crystal structure.Joshua Gild Jeffrey Braun Kevin Kaufmann Eduardo Marin Tyler Harrington Patrick Hopkins Kenneth Vecchio Jian Luo 2019Journal of Materiomics2019,5,3:27
2Cultured meat in western media: The disproportionate coverage of vegetarian reactions, demographic realities, and implications for cultured meat marketing显示文摘This paper examines the media coverage of the 2013 London cultured meat tasting event, particularly in the United States, Canada, and the United Kingdom. Using major news outlets, prominent magazines covering food and science issues, and advocacy websites concerning meat consumption, the paper characterizes the overall emphases of the coverage, the tenor of the coverage, and compares the media portrayal of the important issues to the demographic and psychological realities of the actual consumer market into which cultured meat will compete. In particular, the paper argues that Western media gives a distorted picture of what obstacles are in the path of cultured meat acceptance, especially by overemphasizing and overrepresenting the importance of the reception of cultured meat among vegetarians. Promoters of cultured meat should recognize the skewed impression that this media coverage provides and pay attention to the demographic data that suggests strict vegetarians are a demographically negligible group. Resources for promoting cultured meat should focus on the empirical demographics of the consumer market and the empirical psychology of mainstream consumers.Patrick D Hopkins 2015Journal of Integrative Agriculture2015,14,2:2
3From river blindness control to elimination:bridge over troubled water显示文摘Background:An estimated 25 million people are currently infected with onchocerciasis(a parasitic infection caused by the filarial nematode Onchocerca volvulus and transmitted by Simulium vectors),and 99%of these are in sub-Saharan Africa.The African Programme for Onchocerciasis Control closed in December 2015 and the World Health Organization has established a new structure,the Expanded Special Project for the Elimination of Neglected Tropical Diseases for the coordination of technical support for activities focused on five neglected tropical diseases in Africa,including onchocerciasis elimination.Aims:In this paper we argue that despite the delineation of a reasonably well-defined elimination strategy,its implementation will present particular difficulties in practice.We aim to highlight these in an attempt to ensure that they are well understood and that effective plans can be laid to solve them by the countries concerned and their international partners.Conclusions:A specific concern is the burden of disease caused by onchocerciasis-associated epilepsy in hyperendemic zones situated in countries experiencing difficulties in strengthening their onchocerciasis control programmes.These difficulties should be identified and programmes supported during the transition from morbidity control to interruption of transmission and elimination.Robert Colebunders Maria-Gloria Basanez Katja Siling Rory J.Post Anke Rotsaert Bruno Mmbando Patrick Suykerbuyk Adrian Hopkins 2018Infectious Diseases of Poverty2018,7,1:1
4Report of the first international workshop on onchocerciasis-associated epilepsy显示文摘Background:Recently,several epidemiological studies performed in Onchocerca volvulus-endemic regions have suggested that onchocerciasis-associated epilepsy(OAE)may constitute an important but neglected public health problem in many countries where onchocerciasis is still endemic.Main text:On October 12-14th 2017,the first international workshop on onchocerciasis-associated epilepsy(OAE)was held in Antwerp,Belgium.The workshop was attended by 79 participants from 20 different countries.Recent research findings strongly suggest that O.volvulus is an important contributor to epilepsy,particularly in meso-and hyperendemic areas for onchocerciasis.Infection with O.volvulus is associated with a spectrum of epileptic seizures,mainly generalised tonic-clonic seizures but also atonic neck seizures(nodding),and stunted growth.OAE is characterised by an onset of seizures between the ages of 3-18 years.Multidisciplinary working groups discussed topics such as how to 1)strengthen the evidence for an association between onchocerciasis and epilepsy,2)determine the burden of disease caused by OAE,3)prevent OAE,4)improve the treatment/care for persons with OAE and affected families,5)identify the pathophysiological mechanism of OAE,and 6)deal with misconceptions,stigma,discrimination and gender violence associated with OAE.An OAE Alliance was created to increase awareness about OAE and its public health importance,stimulate research and disseminate research findings,and create partnerships between OAE researchers,communities,advocacy groups,ministries of health,non-governmental organisations,the pharmaceutical industry and funding organizations.Conclusions:Although the exact pathophysiological mechanism underlying OAE remains unknown,there is increasing evidence that by controlling and eliminating onchocerciasis,OAE will also disappear.Therefore,OAE constitutes an additional argument for strengthening onchocerciasis elimination efforts.Given the high numbers of people with epilepsy in O.volvulus-endemic regions,more advocacy is urgently needed to provide anti-epileptic treatment to improve the quality of life of these individuals and their families.Robert Colebunders Michel Mandro Alfred K.Njamnshi Michel Boussinesq An Hotterbeekx Joseph Kamgno Sarah O’Neill Adrian Hopkins Patrick Suykerbuyk Maria-Gloria Basanez Rory J.Post Belen Pedrique Pierre-Marie Preux Wilma A.Stolk Thomas B.Nutman Richard Idro 2018Infectious Diseases of Poverty2018,7,1:1
