Current health and physical education subject guidelines from the Australian Curriculum Assessment and Reporting Authority state that puberty education should be introduced to students between year levels five to six ...

Vaccine hesitancy has been described as any delay or refusal of vaccines despite their availability and is increasing in Australia and other middle to high-income countries. The aim of this study is to gain a deep understanding of the experiences and influences on vaccine hesitant children and their families. A qualitative interview approach was undertaken with vaccine hesitant parents and pregnant ...

Estimating the density of space debris as a function of orbital elements and size is crucial for determining the risk of collision of spacecraft. For objects 1 cm or larger in diameter, this information can be obtained using beam park observations made with powerful ground based radars. This study presents a novel technique for estimating the density of space debris as a function of orbital elements ...

Fruen fra Havet handler om Ellida Wangels psykiske krise og dens løsning. Hennes mann, legen Johannes Wangel, framstår som bekymret og omsorgsfull. Det antydes at han gir henne medisiner, men det nevnes ikke hvilke. Mange har ment at Ibsen i stykket foregriper Freuds «snakkekur» med flere år. I denne artikkelen utforsker jeg de psykiske problemene Ellida har, hvilke legemidler det kunne være snakk ...

I denne artikkelen analyserer vi framveksten av to framtidsvisjoner for regionen Lofoten. Den ene visjonen handlet om oljeutvinning. Den andre samfunnsvisjonen framstiller grønn omstilling som en regional vekstmulighet, og har vokst fram i perioden etter at oljevisjonen mistet sitt fotfeste. Vi analyserer hvilke argumenter som har vært sentrale i den lokale debatten om oljevirksomhet, og kobler ...

The Atg8 family of ubiquitin-like proteins play pivotal roles in autophagy and other processes involving vesicle fusion and transport where the lysosome/vacuole is the end station. Nuclear roles of Atg8 proteins are also emerging. Here, we review the structural and functional features of Atg8 family proteins and their protein-protein interaction modes in model organisms such as yeast, Arabidopsis, ...

The Northern Svalbard Composite Tectono-Sedimentary Element (CTSE) comprises Proterozoic, Early Paleozoic, and Devonian sedimentary rocks preserved in northern Svalbard and on the adjacent shelf margin. Here, the sedimentary strata of the CTSE are preserved between complexes of metamorphic and crystalline basement rocks. The Northern Svalbard CTSE covers four main tectonostratigraphic elements: ...

More than half of the population with HIV in the world live in sub-Saharan Africa. HIV-associated chronic lung disease is the most prevalent comorbidity among children and adolescents with HIV in this region. The pathogenesis is multifactorial and thought to be a result of chronic immune activation and repeated lung injury. CD4+ T-cells are the main target for HIV infection. As the majority of CD4+ ...

The cosmopolitan apex predator killer whale (Orcinus orca) is one of the species worldwide with the highest levels of persistent organic pollutants (POPs) in their tissues. The knowledge of how POPs may affect the species is limited, likely due to the ethical, legal, and practical challenges of researching toxicology on free-ranging marine mammals. The use of in vitro models has proved to be a ...
