A diallel cross experiment of 4 rice (Oryza sativa L.) female and 6 male varieties was conducted to study the genetic effects and their interaction with salt-stress condition of 7 agronomic traits in normal and salt-stressed planting conditions. The panicle length (PL), effective number of panicles per plant (ENP), plumped number of grains per panicles (PNG), total number of grains per panicles...

Besides young children, pregnant women are at high risk of malaria in highly endemic countries. This paper reviews evidence from studies conducted in Papua New Guinea (PNG) in the last 20 years on the burden and prevention of malaria in pregnancy and highlights gaps in our knowledge of malaria in pregnancy in PNG. Overall, primigravidae were found to be at higher risk than multigravidae, with u...

OBJECTIVE To assess capacity to provide essential surgical services including emergency, obstetric and anaesthesia care in Papua New Guinea (PNG) in order to support planning for relevant post-2015 sustainable development goals for PNG. DESIGN Cross-sectional survey. SETTING Hospitals and health facilities in PNG. PARTICIPANTS 21 facilities including 3 national/provincial hospitals, 11 di...

We report on the electrospinning of poly(vinylidene fluoride-hexafluoropropylene) [P(VDF-HFP)] nanofibers doped with silver nanoparticles for the preparation of a polymer based nanogenerator (PNG). It has been found that the yield of the piezoelectric phase is increased by the addition of silver nanoparticles. Furthermore, defects in the P(VDF-HFP) electrospun fibers are removed resulting in a ...

The primordial non-Gaussianity (PNG) in matter density perturbation is a very powerful probe of the physics of the very early Universe. The local PNG can induce a distinct scale-dependent bias on the large scale structure distribution of galaxies and quasars, which could be used for constraining it. We study the detection limits on PNG from the surveys of the LAMOST telescope. The cases of the ...

Nanogold particles are commonly used in nanomedicine. We generated physical nanogold (pNG) conjugated with different ratios of epigallocatechin-3-gallate (EGCG) and evaluated its physicochemical properties, antioxidant activity, and cytotoxicity in vitro as well as anticancer activity in vivo. Results showed that the EGCG-pNG conjugates were successfully prepared at ratios between 23:1 and 23:5...

The nature of the planetary noble gas (PNG) carrier or Q-phase [1] in meteorites is still a subject of discussion. Failure to identify and isolate this carrier since the first successful concentration of it by a factor of ~200 in an Allende HF-HCl residue [1] and establishing it to be carbonaceous in nature [2], led eventually to the so-called “labyrinth” theory [3], according to which PNG init...

EDITORIAL Why computed tomography is needed in Papua New Guinea Computed tomography (CT) was introduced in the 1970s and rapidly transformed diagnostic imaging, especially in neurology and neurosurgery. Direct images of brain pathology could be seen and therapy could be precisely directed to the pathology. As a result of more accurate diagnosis, the mortality of various conditions began to fall...

Despite the rapid growth of the Internet for storage and display of World Wide Web–based teaching files, the available image file formats have remained relatively limited. The recently developed portable networks graphics (PNG) format is versatile and offers several advantages over the older Internet standard image file formats that make it an attractive option for digital teaching files. With ...

BACKGROUND The social and cultural positions of both researchers and research participants influence qualitative methods and study findings. In Papua New Guinea (PNG), as in other contexts, gender is a key organising characteristic and needs to be central to the design and conduct of research. The colonial history between researcher and participant is also critical to understanding potential po...
