The study of the interaction between highly charged ions and solid surfaces not only has great significance for basic scientific research such as atomic physics, astrophysics, high energy density physics but also promising application prospects in biomedicine, nanotechnology, surface analysis, microelectronics. In this paper, intermediate Rydberg states formed during <inline-formula><t...

In late September 2012, I travelled from Sydney to the small village of Valoka in West New Britain province of Papua New Guinea to set up an ultrasound service there. In early 2011 I had replied to a post on the ASA website from the Kimbe Assistance project, who are supplying much-needed equipment and consumables to the small rural clinic on the west coast island province of New Britain. A Phil...

BACKGROUND The success of health programs is influenced not only by their acceptability but also their ability to meet and respond to community expectations of service delivery. The World Health Organization (WHO) and the Joint United Nations Programme on HIV/AIDS (UNAIDS) have recommended medical male circumcision (MC) as an essential component of comprehensive HIV prevention programs in high ...

CONTEXT Although Papua New Guinea (PNG) has made some progress in social development over the past 30 years, the country's Human Development Index has slowed in recent years, placing it below the regional average. In 2012, the estimated HIV prevalence for adults aged 15-49 years was 0.5% and an estimated 25,000 people were living with HIV. Although reduced from previous estimates, the country's...

OBJECTIVE Papua New Guinea (PNG) has among the highest estimated prevalences of genital Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Trichomonas vaginalis (TV) of any country in the Asia-Pacific region. Diagnosis and treatment of these infections have relied on the WHO-endorsed syndromic management strategy that uses clinical presentation without laboratory confirmation to make tr...

INTRODUCTION The importance of Plasmodium vivax in malaria elimination is increasingly being recognized, yet little is known about its population size and population genetic structure in the South Pacific, an area that is the focus of intensified malaria control. METHODS We have genotyped 13 microsatellite markers in 295 P. vivax isolates from four geographically distinct sites in Papua New G...

This paper explores the issues concerning women's groups in the context of women's network in Papua New Guinea (PNG) and from an association with such a network in West New Britain province. The women's groups in PNG often came into existence under the influence of colonial rule and as an adjunct to the Church. Some 20 years later, their vulnerability to colonization by other development fact...

BACKGROUND AND AIMS The genetic and morphological variation in the sago palm (Metroxylon sagu, Arecaceae) in Papua New Guinea (PNG) was investigated. METHODS Amplified fragment length polymorphism (AFLP) was used to investigate the genetic structure of 76 accessions of M. sagu, collected in seven wild and semi-wild stands in PNG. KEY RESULTS An analysis of ten quantitative morphological var...

Digital images are used to safeguard confidential & important information. But the problem is providing authentication, integrity and data security to these digital images. In existing techniques of security and authentication conventional watermarking schemes are used. In these techniques cryptography is the basic method adopted which has problem of tampering of information easily by hackers. ...
