Eutrophic reservoirs are characterized by excessive presence of plant and algal growth due to favourable environmental conditions, temperature, light nutrients. Human activities accelerate this phenomenon provoke dramatic changes the aquatic ecosystems. The monitoring water quality these ecosystems study effects they have on environment demand a large amount spatial temporal information, which ...

Background: Qual2k is a stream water quality model and was used to evaluate the water quality of the Kine-Vars River and assess the response of the river to nutrient management strategies. Methods: For that purpose, 7 sample stations were selected and surface water samples were collected in the winter and summer of 2012 and were analyzed for temperature, dissolved oxygen, biological oxygen dem...

In this study, the influence of eutrophication on arsenic speciation in lake waters was investigated. Surface water samples (n=1-10) were collected from 18 lakes in Japan during July 2007 and February 2008. The lakes were classified into mesotrophic (7 lakes) and eutrophic (11 lakes) based on the total phosphate (T-P) and chlorophyll-a (Chl-a) concentrations in water column. Inorganic, methylat...

INTRODUCTION Patients suffering from long standing dysphagia need tube feeding through gastrostomy. Nutritional assessment of these patients is challenging and must be supported on objective data, including anthropometric evaluation. AIM The aim of this study was the evaluation of the usefulness of anthropometry for identifying and grading malnutrition, as part of the initial assessment of pa...

This study aimed to elucidate the effects of periphyton on the microprofiles of oxygen (O2), pH, and oxidation-reduction potential around the stems and leaves of a submerged macrophyte Potamogeton malaianus and on the plant growth in the eutrophic shallow Taihu Lake, China. The microprofiles were measured using a motorized microprofiling system equipped with microsensors. The leaf age of the ma...

Cyanobacteria are found worldwide in various habitats. Members of the picocyanobacteria genera Synechococcus and Prochlorococcus dominate in oligotrophic ocean waters. Other picocyanobacteria dominate in eutrophic fresh or brackish waters. Usually, these are morphologically determined as species of the order Chroococcales/clade B2. The phytoplankton of a shallow, eutrophic brackish lagoon was i...

INTRODUCTION Obesity causes alterations in cardiac autonomic function. However, there are scarce and conflicting data on this function with regard to heart rate variability in obese children. OBJECTIVE To compare the autonomic function of obese and eutrophic children by analyzing heart rate variability. METHODS One hundred twenty-one children (57 male and 64 female) aged 8 to 12 years were ...
