The word is analogous to the German aufwuchs, which means “to grow upon,” but some authors (e.g., Round, 1981) argue against using it because it is often used incorrectly to describe only the algal community and is imprecise with regard to habitat. Its use probably will not be ...
This means that temperature changes in the water are more gradual, particularly so in more vast areas of water. When this freshwater ecosystem is habitable, many factors will come into play determining the overall makeup of the environment in which organisms will have to adapt to....
1. In lenticulating apparatus, in combination, an embossing roller having a multiplicity of close- 1y adjacent minute, lenticular shaped depressions distributed continuously over the surface of said roller, film handling means including means for maintaining film under pressure against the surface of ...
This means that damming the river and impeding water behind it can cause profound impacts on the physicochemical parameters and the zooplankton community in the water body. A large number of studies examined the different topics of the water quality parameters either in Nasser Lake or in Nile ...
I have found that a filter or diaphragm for the illumination- of the negative film in printing lenticular film can be dispensed with when illuminating the negative film by means of an incandescent lamp the coils of which are arranged in the form of a stair in such a manner that a line dr...
The order obtained by means of discriminant analysis may be explained as resulting from two processes: succession and microsuccession.doi:10.1080/00207239708711108Copes, C. D.Kieffer, L. A.Sierra, Patricia De LaMarino, F.Taylor & Francis GroupInternational Journal of Environmental Studies...
The antimicrobial activities of the extracts were tested against test microorganisms by means of disk diffusion method. Four gram - positive bacteria, four Gram - negative bacteria, one mold and one candida were used tested microorganism. Our data showed that Gram-positive bacteria were more ...
The paucity of permanent waters in arid and semi-arid regions means, of course, that temporary waters have an ecological significance much greater there than in more temperate regions. For example, throughout most of continental Australia, waterfowl are closely dependent for survival on the ...
This means Lingambudi lake water requires 6 days to stabilize without undergoing mixing process at a dosage of 100mg/L. At 10th day the phosphate and nitrate removal efficiency was about 50-60% for both the water samples. Hence Lentic and Eutrophic state of the lake can be reduced and the...
