This study is a contribution to the study of the spatial evolution of the properties of the municipal lake of Yaounde-Cameroon. The objective was the characterization of the physico-chemical, bacteriological and organoleptic parameters of water of this lake in order to provide the scientifically exploitable data. To understand the sources and the evolution of the pollution of this lake, we carr...

Spatiotemporal modelling of land use/cover change (LUCC) has become increasingly important in recent years, especially for environmental change and regional planning. There have been many approaches and software packages for modelling LUCC, but developing a model for a specific region is still a difficult task, because it requires large volume of data input and elaborate model adjustment. Fuxia...

Long-term information of phytoplankton bloom is critical for assessing the processes driving blooms in lakes. A three-decade survey of the phytoplankton blooms was completed for Erhai Lake from 1987 to 2016 with Landsat imagery. A modified three-band model using Landsat broad bands is developed by comparing reflectance data from Landsat imagery to two field datasets. The model is applied to the...

Definition: The term “lake effect” generally refers to the effect of any lake in modifying the weather about its shore and for some distance downwind. In the United States, this term is applied specifically to the region about the Great Lakes or the Great Salt Lake. More specifically, lake effect often refers to the generation of sometimes spectacular snowfall amounts to the lee of the Great La...

We give a brief summary of present bounds on the size of possible extra-dimensions from collider experiments. Based on talks given by I.A. at Pascos99 [1] Lake Tahoe, California, 10-16 December 1999 and by K.B. at Rencontres de Moriond [2] on Electroweak Interactions and Unified Theories, Les Arcs, France, March 11-18, 2000.

Taihu Lake in China is suffering from severe eutrophication partly due to non-point pollution from the watershed. There is an increasing need to identify the regions within the watershed that most contribute to lake water degradation. The selection of appropriate temporal scales and lake indicators is important to identify sensitive watershed regions. This study selected three eutrophic lake ar...

Fully atomistic molecular dynamics simulations were utilized to examine melt dispersions of graphene nanosheets in a poly(ethylene glycol) (PEG) matrix, in a wide temperature range and for two different polymer sizes. The resulted mixtures were characterized by the organization of graphene in oligomeric clusters. No indications for polymer crystallization were noted in the examined time window....
