Badbury Rings in a northwest direction (visible today as a thin strip of woodland) heading for the Roman fort at Hod Hill. At an early stage, this road formed a junction with Ackling Dyke, a Roman road which headed northeast to Old Sarum ("Sorviodunum"). Another road ran across country in a north by northwest direction towards Bath ("Aquae Sulis")., and another ran south to a small port in Poole Harbour ("Moriconium", modern Hamworthy). The final road (still used as a modern trackway on the west side of Badbury Rings) ran in a southwest direction through the settlement of "Vindocladia" heading towards Dorchester
Aphanizomenon flos-aquae (dietary supplement) from the air, and water to synthesize proteins, carbohydrates, and lipids. AFA is also able to directly use molecular nitrogen from the air to produce proteins and other nitrogen-containing biomolecules. This ability is widespread in prokaryotes, but unknown in eukaryotes. "Aphanizomenon flos-aquae" as a species has both toxic and non-toxic forms. While benefits have been indicated, toxicity has been shown in some strains of the species "Aphanizomenon flos-aquae", with cylindrospermopsin and saxitoxins present, and microcystins found contaminating AFA dietary supplements. The World Health Organization's "Guidelines For Drinking Water Quality" note Anatoxin-a, saxitoxins, and cylindrospermopsins are present in the Aphanizomenon genus.
