BACKGROUND The terrestrial land surface in West Africa is made up of several types of savanna ecosystems differing in land use changes which modulate gas exchanges between their vegetation and the overlying atmosphere. This study compares diurnal and seasonal estimates of CO2 fluxes from three contrasting ecosystems, a grassland, a mixture of fallow and cropland, and nature reserve in the Sudan...

Early warning systems for food security require accurate and up-to-date information on the location of major crops in order to prevent hazards. A recent systematic analysis of existing cropland maps identified priority areas for cropland mapping and highlighted a major need for the Sahelian and Sudanian agrosystems. This paper proposes a knowledge-based approach to map cropland in the Sahelian ...

A passage to India by E.M. Forster is a modern novel written in 1924. It describes the modern movement in that period, so we could say that each movement of the human beings has its own characterizations which recognize it from other periods. Forester’s novel has its own features which recognize it from other ages in English literature. A Passage to India is one of the novels affected by Modern...

BACKGROUND Gamma-enolase, known also as neuron-specific enolase (NSE), is an enzyme of the glycolytic pathway, which is expressed predominantly in neurons and cells of the neuroendocrine system. As a tumour marker it is used in diagnosis and prognosis of cancer; however, the mechanisms enrolling it in malignant progression remain elusive. As a cytoplasmic enzyme gamma-enolase is involved in inc...

microbe-associated molecular patterns (mamps) play key roles as activators of the innate immune response in animals and, analogously, as elicitors of defense responses in plants. however, there are not much investigations concerning their real importance in plant resistance against pathogens. here we used derivatives of flagellin and ef-tu as two well-known mamps against some important fungal a...
