Research ArticleOpen accessIn the abstractThe Spatial-Temporal Variability of Nitrates in a Section of the Cuneo Plain (North West Italy)Massimo Vincenzo Civita, Adriano Fiorucci, Bartolomeo VignaThe study of an aquifer system is very important, but also very complicated because of the high temporal and spatial variabilities of a system and because of the phenomena that are at play within the system. It is from these problems that the necessity arises of finding methods that are able to extend point knowledge to an entire area, while … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 6,733 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Air Quality in Kuwait Urban and Industrial AreasHamad B Matar, Talal Almutairi, Nayef Z. Al-MutairiThis paper describes the research carried out to investigate air quality in Kuwait. It examined the results of several years of pollutants data provided by Kuwait Environment Public Authority. The data were obtained from a number of fix monitoring stations. The results of the time series analysis have shown that monitored exposures vary substantially and are unique to the location … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 8 Apr 2020 · 7,979 accessesView PDFCite

Research ArticleOpen accessIn the abstractEFFECT OF LIMING AND FERTILIZER APPLICATION IN HEMIC AND SAPRIC OF TROPICAL PEAT: PHOSPHORUS MINERALIZATION, INFRA-RED SPECTROSCOPY AND MICROSCOPYAmeera Abdul Reeza, Aminuddin Hussin, Ahmad Husni Mohd Hanif, Mohd Aspollah Md. SukariThis study was conducted to investigate the changes in nutrient level P as well as in the structural and functional groups upon the decomposition of Hemic and Sapric peat material due to application of lime and fertilizers. The peat materials were left to decompose for 8 weeks under laboratory incubation and samples were taken for the determination of extractable P … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 31 Mar 2014 · 8,393 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Evaluation of Adaptive Filter and Neuro-Fuzzy Filter in Artifacts Removal From Electroencephalogram SignalPaulchamy Balaiah, IlavennilaProblem statement: This study presents an effective method for removing mixed artifacts (EOG-Electro-ocular gram, ECG-Electrocardiogram, EMG-Electromyogram) from the EEG-Electroencephalogram records. The noise sources increases the difficulty in analyzing the EEG and obtaining clinical information. EEG signals are multidimensional, non-stationary (i.e., statistical properties are not invariant in time), time domain biological signals, which are not reproducible. It is supposed to contain … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 15 Aug 2012 · 7,090 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Shrimp Farm Effluent on Water Quality in Coastal Areas of the World Heritage-Listed Ha Long BayThuyet D. Bui, Jim Luong-Van, Chris M. AustinProblem statement: Shrimp farming has rapidly developed in coastal areas of the World Heritage-listed Ha Long Bay since the last decade. Effluent discharged from shrimp farms with high levels of nutrient waste may cause eutrophication in receiving waterways. Therefore, assessing water quality at tidal creeks receiving shrimp farm effluent in coastal areas of Ha Long Bay supports environmental protection and … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 3 Mar 2012 · 11,289 accessesView PDFCite
