Roots and tubers value chain development and food and nutrition security - PNG
Root and tuber crops (RTCs) have been the mainstay for 85% of Papua New Guineans, contributing to food security and household income. Although RTCs have special importance in Papua New Guinea (PNG), research and development on increasing their production has been minimal. Eighty percent of the population is reliant on agriculture, but the government focusses on non-renewable minerals and petroleum production. In this paper, the status of RTCs in PNG is outlined. Linking the private sector with farmer groups and government support, is key for RTC development.
Host-Pathogen Interactions
Although many insects successfully live in dangerous environments exposed to diverse communities of microbes, they are often exploited and killed by specialist pathogens. In the process of the co-evolution of insects and entomopathogenic microorganisms, they develop various adaptive systems that determine the sustainable existence of dynamic host–parasite interactions at both the organismic and population levels.
The Military and Democracy in Asia and the Pacific
In The Military and Democracy in Asia and the Pacific, a number of prominent regional specialists take a fresh look at the military's changing role in selected countries of Asia and the Pacific, particularly with regard to the countries' performance against criteria of democratic government. Indonesia, Thailand, the Philippines, Burma, Pakistan, Bangladesh, South Korea, Fiji and Papua New Guinea all fall under the spotlight as the authors examine the role which the military has played in bringing about changes of political regime, and in resisting pressures for change.
MRI Contrast Agents
This book describes the multiple aspects of (i) preparation of the magnetic core, (ii) the stabilization with different coatings, (iii) the physico-chemical characterization and (iv) the vectorization to obtain specific nanosystems. Several bio-applications are also presented in this book. In the early days of Magnetic Resonance Imaging (MRI), paramagnetic ions were proposed as contrast agents to enhance the diagnostic quality of MR images. Since then, academic and industrial efforts have been devoted to the development of new and more efficient molecular, supramolecular and nanoparticular systems. Old concepts and theories, like paramagnetic relaxation, were revisited and exploited, leading to new scientific tracks. With their high relaxivity payload, the superparamagnetic nanoparticles are very appealing in the context of molecular imaging but challenges are still numerous: absence of toxicity, specificity, ability to cross the biological barriers, etc.
