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. Unité mixte du CNRS et de l’EP, UMR 7644.
یک روش تکثیر درون شیشه¬ای کارآمد به منظور تکثیر گونه rosa hybrid واریته city of leads از طریق تکثیر جوانه جانبی بررسی گردید. در ابتدا ریزنمونه¬ها به منظور استقرار بر روی دو محیط کشت ms و van der salm در ترکیب با غلظت¬های مختلف هورمون¬های ba و naa کشت گردیدند. بیشترین درصد استقرار ریزنمونه¬ها (100 درصد) و تعداد نوساقه¬ها (4/3 نوساقه در هر ریزنمونه) در محیط van der salm حاوی 2 میلی¬گرم در لیتر ba...
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...
During the Holocene Lake Orūmiye has been subjected to significant changes in climate. These have impacted the surround vegetation and runoff, and erosion rates of the surrounding basin. Shifts in seasonal rainfall from winter to summer dominated patterns have resulted in dramatic changes in the Orūmiye Basin’s vegetation cover from grass to shrub dominated communities. The degree of ground sur...
The surface water quality of some stagnant water bodies (ponds and lakes—Obi Lake, Usede pond, Oguta lake, Omuku pond, Ugheghe pond, Karabodone lake, Abua lake, Ikarama lake, Tenmako lake, and Adiegbe lake) in the Niger Delta area of Nigeria have been investigated experimentally by analysing the physico-chemical and biological characteristics of the surface water samples. Results show: pH (5.10...
