Low “gradient”, low flow aortic stenosis [PDF]

open access: yesHeart, 2006
Aortic stenosis is thought to have a long, asymptomatic latent phase during which the risk of sudden death is low. In fact symptoms can be revealed by treadmill exercise in a large proportion of apparently asymptomatic patients.1 Patients may limit exercise to avoid symptoms or may fail to recognise the presence of exertional breathlessness or ascribe ...

Hydrogeological approach to the regional analysis of low flow in medium and small streams of the hilly and mountainous areas of Serbia [PDF]

open access: yesGlasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2006
During the long rainless spells of the dry season, flows in medium and small streams get reduced to what is generally known as "low flow". For ungauged streams, the controlling "low flows" are determined using the regional analysis method.
