Trophic status of rivers in the Forth catchment, Scotland

Aquatic Conservation: Marine and Freshwater Ecosystems, 1997
1. An increase in nutrient concentrations in fresh water may pose a threat to water quality, biodiversity, and the uses to which these resources are subject. Compared with standing waters, the trophic status of running water has been neglected with few studies describing the extent of eutrophication in rivers. 2.

ASSESSING THE TROPHIC STATUS OF LAKES WITH AQUATIC MACROPHYTES

Lake and Reservoir Management, 1984
We propose that as a first approach the trophic status of natural and artificial lakes having growths of aquatic macrophytes may be assessed by using the total nutrient concentration in the water c...

Trophic venous ulcers and their relationship with the immune status.

Angiologiia i sosudistaia khirurgiia = Angiology and vascular surgery, 2007
This paper describes the results of an original study into the systemic and local immunity in 25 patients with trophic venous ulcers. The authors discovered a number of significant parameters demonstrating the influence of the immune status on the formation of venous ulcers and tempo of their healing.

Respiratory muscles in COPD: regulation of trophical status.

Verhandelingen - Koninklijke Academie voor Geneeskunde van Belgie, 2002
Chronic obstructive pulmonary disease, COPD is a highly prevalent disorder of increasing medical and socio-economical importance. It is characterized by irreversible airflow obstruction. Besides airflow obstruction also other features are present. One of these is respiratory muscle weakness.
