Humusica 2, article 14: Anthropogenic soils and humus systems - Comparing classification systems

The aim of this article is to present a sort of state of the art from a soil classification point of view. How far are soils from their original natural state? A few years ago, the two most important soil classification systems added a classification of anthropogenic soils. Even so, although the concept of anthropogenic soil differs slightly in the two systems, it is easy to recognize these soi...

Humusica 2, article 18: Techno humus systems and global change – Greenhouse effect, soil and agriculture

The article is structured in six sections. A first section is dedicated to the state of the art concerning climatic change and agriculture. Internet-available IPCC maps and cartographic documents made by scientific research centres were used for illustrating forecasted climatic changes. In sections 2 and 3, bibliographic evidences were collected for supporting a vegetation and soil co-evolution...

Cancer Immunity 2:15 (2002) - ARTICLE

Dendritic cells (DCs) are professional antigen-presenting cells currently being discussed as a potent tool for antitumor vaccination strategies. The approach consisting of the in vitro generation of DC-tumor cell hybrids may be advantageous for individualized vaccines since there is no need for the determination of MHC-restricted tumor-associated antigens recognized by T cells. As recent vaccin...

Humus forms in terrestrial ecosystems: a framework to biodiversity

Humus forms are the seat of most biological transformations taking place in terrestrial ecosystems, being at the interface between plants, animals and microbes. The diversity of terrestrial humus forms (mor, moder and mull) can be attributed to the existence of different patterns (strategies) for the capture and use of resources by ecosystems, in ascending order of biodiversity and bioavailabil...
