1. Scarcity, Abundance and Sufficiency: Contributions to Social and Economic Theory
Abstract : Economic sociology has established itself as a strong and vibrant field in the social sciences. A number of significant studies have been conducted on the relation between the economy and society: on firms, markets, networks, money, and general action theory. But little has been done on the issues of scarcity, abundance, and sufficiency (SAS). READ MORE

2. Chemical Abundance Analysis of Population II Stars : The Summary Includes a Background in General Astronomy
Abstract : We are made of stardust in the sense that most atomic nuclei around us have been formed by stars. Stars synthesise new elements and expel them to the interstellar medium, from which later new generations of stars are born. We can map this chemical evolution by analysing the atmospheric contents of old Galactic halo stars. READ MORE

3. Skin hydration - How water and osmolytes influence biophysical properties of stratum corneum
Abstract : The outermost layer of skin (i.e., the stratum corneum, SC) is the interface that separates the water-rich inside of the body from the relatively dry external environment. SC forms an effective permeability barrier, which has to be overcome in transdermal drug delivery. READ MORE

4. Species interactions in streams - effects of predation, competition and ecosystem properties
Abstract : Stream ecosystems are dynamic and they have an inherent environmental variability. Organisms that live in streams are adapted to the continuously changing environment and the presence or absence of species are determined by their environmental requirements, while abundance is most often affected by interactions, such as competition and predation, with other species that are found in the same habitat.

5. Diatom and Sedimentological Investigations on West Antarctic Shelf Sediment
Abstract : Climate and environmental change following the retreat of the last glacial ice sheet in the Antarctic Peninsula has been interpreted, employing diatom abundance, relative abundance of Chaetoceros resting spores and diatom assemblages as proxies. These together with sedimentological data and radiocarbon dating, suggest four major events that can be further subdivided. READ MORE
