Isolation of Coxsackievirus A24 variant from patients with hemorrhagic conjunctivitis in Cuba, 2008-2009

BACKGROUND: An outbreak of acute hemorrhagic conjunctivitis occurred in Cuba in 2008 and 2009.OBJECTIVE: To determinate the etiological agent associated with the Cuban outbreaks of acute hemorrhagic conjunctivitis during 2008 and 2009.STUDY DESIGN: Conjunctival swabs and/or faecal samples from 382 patients with clinical diagnosis suggestive of acute hemorrhagic conjunctivitis were subject to viral

Importing political polarization? The electoral consequences of rising trade exposure

Has rising import competition contributed to the polarization of US politics? Analyzing multiple measures of political expression and results of congressional and presidential elections spanning the period 2000 through 2016, we find strong though not definitive evidence of an ideological realignment in trade- exposed local labor markets that commences prior to the divisive 2016 US presidential ele

Responses of soil extracellular enzyme activities and microbial community properties to interaction between nitrogen addition and increased precipitation in a semi-arid grassland ecosystem

Both atmospheric nitrogen (N) deposition and precipitation can strongly impact below-ground biogeochemical processes. Soil extracellular enzymes activities (EEAs) and microorganisms are considered as the key agents in ecosystem nutrient cycling. However, how the interaction between increasing N deposition and precipitation may affect soil EEAs and microbes remain poorly understood. In a 5-year fie

Effects of polyamine pool manipulation on genes expressed during the cell cycle

Popular Abstract in Swedish En cell förökar sig genom delning. Före delningen måste den växa och fördubbla cellinnehållet för att det ska finnas material till två nya celler. En cellcykel är de händelser som sker från det en cell delat sig tills den delar sig igen [Fig 1]. En cellcykel kan delas in i fyra faser som cellen måste genomgå innan den är mogen att dela sig. Under första fasen, G1, tillvThe polyamines - putrescine, spermidine and spermine - are polycations found within cells. They have been shown to be essential for optimal cell proliferation and cell survival. Cells maintain their polyamine levels in a well-regulated system involving biosynthesis, catabolism and uptake/excretion. The biosynthetic enzymes - ornithine decarboxylase (ODC) and S-adenosylmethionine decarboxylase (Ado

SME creation facilitation process at Universities

Much research on SMEs is aimed at researching SMEs after the fact that they have become SMEs. However all SMEs as well as larger companies start as an idea in the head or heads of one or many persons - the prospective entrepreneurs. The purpose of this paper is to investigate how SMEs can be created by transforming ideas into real companies. More specifically we will investigate if and how Univers

The Virtual Museum of the Western Han Dynasty: 3D Documentation and Interpretation

This project, aimed to the digital documentation of archaeological sites, artifacts and cultural relics of the Western Han Dynasty, started in 2008. The anticipated outcome will be the creation of a virtual museum, based on collaborative environments, dedicated to the Western Han Dynasty and able to integrate new archaeological datasets coming from fieldwork activities (most part of them unpublish

An Improved Spatial Downscaling Procedure for TRMM 3B43 Precipitation Product Using Geographically Weighted Regression

Precipitation data at high spatio-temporal resolution are essential for hydrological, meteorological, and ecological research in local basins and regions. The coarse spatial resolution (0.25°) of Tropical Rainfall Measuring Mission (TRMM) 3B43 product is insufficient for practical requirements. In this paper, a multivariable geographically weighted regression (GWR) downscaling method was developed

Turning the tanker? Exploring the preconditions for change in the global petrochemical industry

Meeting the goals set out in the Paris Agreement will require rapid and deep reductions of greenhouse gas emissions (GHG) across all sectors of the global economy. Like all major societal transformations, this climate transition will impact both social and technical aspects of society and, depending on how it evolves, will reallocate social and economic benefits and costs differently. Recognising

Informing the SWAT model with remote sensing detected vegetation phenology for improved modeling of ecohydrological processes

The Soil and Water Assessment Tool (SWAT) model has been widely applied for simulating the water cycle and quantifying the influence of climate change and anthropogenic activities on hydrological processes. A major uncertainty of SWAT stems from the poor representation of vegetation dynamics due to the use of a simplistic vegetation growth and development module. Using long-term remote sensing-bas

A global assessment of the species composition and effectiveness of watermelon pollinators and the management strategies to inform effective pollination service delivery

For most food crops the identity and efficiency of pollinators across key growing regions remains a significant knowledge gap that needs to be addressed before we can develop crop-specific approaches for pollination service delivery. Here, we conducted a systematic literature review and meta-analysis on watermelon (Citrullus lanatus (Thunb. Matsum. & Nakai)), a globally important fruit crop, t

Questioning Transcription: The Case for the Systematic and Reflexive Interviewing and Reporting (SRIR) Method

The recording and verbatim transcription of interviews is often considered to be one of the more tedious but necessary aspects of the in-depth qualitative research process. While transcription is undoubtedly a necessary methodological tool for researchers focusing specifically on discourse and language, it has also been widely adopted by researchers across the social sciences, and is sometimes adv

The technology-adjusted balance of emissions embodied in trade: Assessing global carbon emission displacement from 1995 to 2009

Increasing global production fragmentation allows for emission displacement, which may counteract advanced nation’s domestic reductions of production-related carbon emissions. Consequently, input-output analysis has become a common tool to measure countries’ carbon footprint and emission trade balances based on national consumption instead of domestically produced CO2 emissions. Nevertheless, trad

Strategic narratives and US military bases in Japan: How ‘deterrence’ makes the Marine base on Okinawa ‘indispensable’

Governed directly by the US from the Battle of Okinawa in 1945 until its reversion to Japan in 1972, the island of Okinawa hosts the majority of US military bases in Japan despite comprising only a fraction of a percent of the total land area. The central government in Tokyo has refused to countenance revision of the status quo in the face of increasing local opposition, including mass protests an

Early Cambrian oxygen minimum zone-like conditions at Chengjiang

The early Cambrian succession at Chengjiang contains the most diverse Cambrian fossil assemblage yet described, and contributes significantly to our understanding of the diversification of metazoans in the Cambrian “explosion”. The Cambrian Period occupies a transitional episode of global ocean chemistry, following the oxygenation of the surface ocean and of shallow marine environments during the
