Pattern Classification and Recognition of Invertebrate Functional Groups Using Self-Organizing Neural Networks
Springer Science and Business Media LLC - Tập 130 - Trang 415-422 - 2006
WenJun Zhang
Self-organizing neural networks can be used to mimic non-linear systems. The main objective of this study is to make pattern classification and recognition on sampling information using two self-organizing neural network models. Invertebrate functional groups sampled in the irrigated rice field were classified and recognized using one-dimensional self-organizing map and self-organizing competitive...... hiện toàn bộ
Patterns of cyanobacterial abundance in a major drinking water reservoir: what 3 years of comprehensive monitoring data reveals?
Springer Science and Business Media LLC - Tập 192 - Trang 1-11 - 2020
Azadeh Golshan, Craig Evans, Phillip Geary, Abigail Morrow, Marcel Maeder, Romà Tauler
The present study provides a detailed analysis of the factors influencing variation in cyanobacterial communities of a large shallow off-river drinking water reservoir on the east coast of Australia. Receiving multiple inflows from two unprotected mixed land-use catchments, the Grahamstown Reservoir is a model example of a reservoir which is highly vulnerable to adverse water quality issues, inclu...... hiện toàn bộ
Evaluation of microbiological air quality and of microclimate in university classrooms

Modeling of atmospheric particulate matters via artificial intelligence methods
Springer Science and Business Media LLC - Tập 193 - Trang 1-15 - 2021
Pınar Cihan, Huseyin Ozel, Huseyin Kurtulus Ozcan
Nowadays, pollutants continue to be released into the atmosphere in increasing amounts with each passing day. Some of them may turn into more harmful forms by accumulating in different layers of the atmosphere at different times and can be transported to other regions with atmospheric events. Particulate matter (PM) is one of the most important air pollutants in the atmosphere, and it can be relea...... hiện toàn bộ
Cumulative influences of a small city and former mining activities on the sediment quality of a subtropical estuarine protected area
Springer Science and Business Media LLC - Tập 186 - Trang 7035-7046 - 2014
Ana Carolina Feitosa Cruz, Marcela Bergo Davanso, Giuliana Seraphim Araujo, Lucas M. Buruaem, Sandra Tédde Santaella, Rodofley Davino de Morais, Denis M. S. Abessa
This study aimed to evaluate the sediment quality in the estuarine protected area known as Cananéia-Iguape-Peruíbe (CIP-PA), located on the southeastern coast of Brazil. The study was designed considering possible negative effects induced by the city of Cananéia on the sediment quality of surrounding areas. This evaluation was performed using chemical and ecotoxicological analyses. Sediments were ...... hiện toàn bộ
Identifying fecal pollution sources using 3M™ Petrifilm™ count plates and antibiotic resistance analysis in the Horse Creek Watershed in Aiken County, SC (USA)
Springer Science and Business Media LLC - Tập 186 - Trang 8215-8227 - 2014
S. Michele Harmon, Ryan T. West, James R. Yates
Sources of fecal coliform pollution in a small South Carolina (USA) watershed were identified using inexpensive methods and commonly available equipment. Samples from the upper reaches of the watershed were analyzed with 3M™ Petrifilm™ count plates. We were able to narrow down the study’s focus to one particular tributary, Sand River, that was the major contributor of the coliform pollution (both ...... hiện toàn bộ
PM2.5 and PM10 Concentrations from the Qalabotjha Low-Smoke Fuels Macro-Scale Experiment in South Africa
Springer Science and Business Media LLC - Tập 69 - Trang 1-15 - 2001
Johann P. Engelbrecht, Leon Swanepoel, Judith C. Chow, John G. Watson, Richard T. Egami
This article presents results from the particulate monitoringcampaign conducted at Qalabotjha in South Africa during the winter of 1997. Combustion of D-grade domestic coal and low-smoke fuels were compared in a residential neighborhood to evaluate the extent of air quality improvement by switchinghousehold cooking and heating fuels.Comparisons are drawn between the gravimetric results from the tw...... hiện toàn bộ
Surface disturbances: Their role in accelerating desertification
Springer Science and Business Media LLC - Tập 37 - Trang 39-57 - 1995
Jayne Belnap
Maintaining soil stability and normal water and nutrient cycles in desert systems is critical to avoiding desertification. These particular ecosystem processes are threatened by trampling of livestock and people, and by off-road vehicle use. Soil compaction and disruption of cryptobiotic soil surfaces (composed of cyanobacteria, lichens, and mosses) can result in decreased water availability to va...... hiện toàn bộ
Using ensemble forecasting to examine how climate change promotes worldwide invasion of the golden apple snail (Pomacea canaliculata)
Springer Science and Business Media LLC - Tập 189 - Trang 1-11 - 2017
Juncheng Lei, Lian Chen, Hong Li
The golden apple snail, Pomacea canaliculata, is one of the world’s 100 most notorious invasive alien species. Knowledge about the critical climate variables that limit the global distribution range of the snail, as well as predictions of future species distributions under climate change, is very helpful for management of snail. In this study, the climatically suitable habitats for this kind of sn...... hiện toàn bộ
