Short communication : HIV type 1 transmitted drug resistance and evidence of transmission clusters among recently infected antiretroviral-naive individuals from Ugandan fishing communities of Lake Victoria

Human immunodeficiency virus type 1 (HIV-1) prevalence and incidence in the fishing communities on Lake Victoria in Uganda are high. This population may play a role in driving the HIV epidemic in Uganda including the spread of transmitted drug resistance (TDR). We report data on TDR in this population among antiretroviral (ARV)-naive, recently infected individuals about 5 years after ARV scaling-u

Virological Response and Antiretroviral Drug Resistance Emerging during Antiretroviral Therapy at Three Treatment Centers in Uganda

BACKGROUND: With the scale-up of antiretroviral therapy (ART), monitoring programme performance is needed to maximize ART efficacy and limit HIV drug resistance (HIVDR).METHODS: We implemented a WHO HIVDR prospective survey protocol at three treatment centers between 2012 and 2013. Data were abstracted from patient records at ART start (T1) and after 12 months (T2). Genotyping was performed in the

Low Rates of Transmitted Drug Resistance Among Newly Identified HIV-1 Seroconverters in Rural Rakai, Uganda

We investigated the rate of transmitted drug resistance (TDR) among HIV-1 seroconverters identified from the Rakai Community Cohort Study (RCCS) survey, a population-based cohort in Rakai District, Uganda. Participants aged 15-49 are interviewed at study visits approximately every 12-18 months and provided a serological sample. Antiretroviral therapy (ART) has been provided free of charge since 20

Exploring interdepencies and common goals in disaster recovery coordination

The present paper seeks to investigate the extent and nature of organizational interdependencies in recovery operations. It focuses on the recovery following the Boxing day tsunami in 2004 in Tamil Nadu, India. It uses the theoretical framework from infrastructure interdependencies to a disaster recovery setting. It takes a case study approach and is based on eighteen interviews conducted in Tamil

Care and consequences of traumatic brain injury in Neolithic Sweden : A case study of ante mortem skull trauma and brain injury addressed through the bioarchaeology of care

A number of papers have provided insight into frequencies of violence-related trauma, especially skull trauma, in Northern European skeletal assemblages dating to the Neolithic and Bronze Age. Although the cases are often well described, they lack further discussion about the consequences of skull trauma for the injured individual and the implications for the surrounding society, especially consid

2D and 3D Nanoscale Imaging Using High Repetition Rate Laboratory-Based Soft X-Ray Sources

In this contribution, we report about tomographic nanoscale imaging using a laser-produced plasma-based laboratory transmission X-ray microscope (LTXM) in the water window. The soft X-ray radiation of the LTXM is provided by a high average power laser-produced (1.3 kHz repetition rate, 0.5 ns pulse duration, 140 W average power) plasma source, a multilayer condenser mirror, an objective zone plate

Behavioral testing and litter effects in the rabbit

Background: Behavioral testing provides an essential approach in further developing our understanding of brain structure and function. The aim of our study was to outline a more expanded approach to cognition- and anxiety-related behavior in the rabbit. Methods: Twenty-one 70-day old rabbits (13 female, 8 male) were exposed to open field test, dark-light box test and object recognition testing wit

A sol-gel integrated dual-readout microarray platform for quantification and identification of prostate-specific antigen

Here, we report a sol-gel integrated affinity microarray for on-chip matrix-assisted laser desorption/ionization time-offlight mass spectrometry (MALDI-TOF-MS) that enables capture and identification of prostate-specific antigen (PSA) in samples. An anti-PSA antibody (H117) was mixed with a sol-gel, and the mixture was spotted onto a porous silicon (pSi) surface without additional surface modifica

A multi-layered performance analysis for cloud-based topic detection and tracking in Big Data applications

In the era of the Internet of Things and social media; communities, governments, and corporations are increasingly eager to exploit new technological innovations in order to track and keep up to date with important new events. Examples of such events include the news, health related incidents, and other major occurrences such as earthquakes and landslides. This area of research commonly referred t

Assessment of Competence in EVAR Procedures : A Novel Rating Scale Developed by the Delphi Technique

OBJECTIVE/BACKGROUND: To develop a procedure specific global rating scale for assessment of operator competence in endovascular aortic repair (EVAR).METHODS: A Delphi approach was used to achieve expert consensus. A panel of 32 international experts (median 300 EVAR procedures, range 200-3000) from vascular surgery (n = 21) and radiology (n = 11) was established. The first Delphi round was based o

DN Debatt ”Partier, lova väljarna att avstå från oetiska digitala metoder”

DN DEBATT 22/3. Det svenska valet hotas av digitala påverkansoperationer där falska robot-konton och så kallade ”dark ads” kan dränka det politiska samtalet. Vi utmanar nu riksdagspartierna: Ge ett enkelt löfte till väljarna om att ni inte kommer att använda er av oetiska metoder på nätet, skriver Jonas Andersson Schwarz, Stefan Larsson och Anders Mildner.

On Giddens: Interpreting Public Relations through Anthony Giddens’s Structuration and Late Modernity Theories

Public relations was historically an isolated theoretical field and an, in practice, undeveloped organizational publicity function for many years. From the perspective of strategy research, theory as well as practice has traditionally been dominated by traditional, rational, linear and functionalistic approaches (Whittington, 2000). The foundation in functionalism has led researchers to focus on e

Experimentell fysik

I denna bok utgår författarna både från experimentalfysikens varför och experimentalfysikens hur. De ger bakgrunder och visioner tillsammans med handfasta kunskaper inom den experimentella fysiken. Boken är främst avsedd för teknologer, naturvetare och lärare. Men framställningen är medvetet utformad för att också kunna nå utanför denna krets, och bokens första halva kräver inga speciella matemati

Researchers’ online visibility : Tensions of visibility, trust and reputation

Purpose – The purpose of this article is to understand what role researchers assign to online representations on the new digital communication sites that have emerged, such as Academia, ResearchGate or Mendeley. How are researchers’ online presentations created, managed, accessed and, more generally, viewed by academic researchers themselves? And how are expectations of the academic reward system

Air pollution online : Everyday environmental information on the social media site Sina Weibo

Purpose: This study explores how information on air pollution is shaped online on an everyday basis, with a particular emphasis on digital devices and digital representations as constitutive of environmental information practices. Furthermore, this research highlights an understudied aspect of air pollution – the digital flow of multimodal representations that citizens encounter and produce in the

Allmänhetens uppfattning kring användandet av övervakningskameror på gator och torg, augusti 2017

Under andra veckan av augusti genomfördes 1000 telefonintervjuer på temat allmänhetens attityd till användandet av övervakningskameror på gator och torg. 90% av allmänheten svarade positivt när de ställdes frågan ”Vad tycker du om övervakningskameror på allmän plats?” uppdelat på 49% som ställde sig mycket positiva och 41% som ställde sig ganska positiva. Vidare ansåg 72% av de tillfrågade att det

New biobased non-ionic hyperbranched polymers as environmentally friendly antibacterial additives for biopolymers

The aim of this research was to develop new biobased non-ionic polymeric additives with significant bacterial inhibition and low leaching potential, so that they can be used to produce biopolymer materials for various applications such as biomedical devices, surgical textile, or food packaging. Two new non-ionic hyperbranched polymers (HBPs) were prepared by a facile solvent-free polymerization of
