Sasaki","doi":"10.11190/JER.16.1","DOIUrl":"https://doi.org/10.11190/JER.16.1","url":null,"abstract":"An experimental study and a regression analysis were carried out to find out the growing patterns of Egeria densa at three different NH 4+ -N concentrations as low (2 mgL -1 ), medium (4 mgL -1 ), and high (6 mgL -1 ). DO concentration during respiration and photosynthesis was monitored in daily basis while plant morphological characteristics were examined with harvesting at six-day interval. There was no any significant difference in morphological characteristics indicated at low and medium NH 4+ -N concentrations (p>0.05). On contrary, the total plant length at high NH 4+ -N concentration has deviated significantly (p<0.01) from other two concentrations after 15 days since commencement of the experiment. Averaged relative growth rates (RGRs) were recorded as 0.05, 0.04 and -0.01 mgday -1 in terms of dry weight production for low, medium and high NH 4+ -N concentrations, respectively. The results of the non-linear regression analysis explained the effect of low and medium concentrations over high concentration of NH 4+ -N, while the medium concentration provided the best correlation coefficient (r 2 = 0.901) for the modeled equation. These results can be used in optimizing the effects of E.densa at tertiary wastewater treatment.","PeriodicalId":15612,"journal":{"name":"Journal of ecotechnology research","volume":"34 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87832281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yearly and spring precipitation increased significantly from 1910 to 2008, and the significance levels were p < 0.10 and 0.01, respectively. The data of daily precipitation were classified into two groups (class 1-4 and 5) separated by the distribution of the data, and class 1-4 precipitation increased significantly. There were 4 significant-climatic jumps (1925-27, 1963, 1979-1982 and 1993) by results of the Lepage test. The averages of yearly precipitation during whole years and the latest period are 215.0 and 280.9 mm/year, respectively. The averages of monthly precipitation in February, October and November during the latest period (1993-2008) is higher than those in the previous periods. That in February during the latest period was especially heavy, when the mean precipitation in February was six times higher than that in the previous period. This change was attributed to the increase in the frequency of storm events in February during the latest period. Monthly precipitation exceeding 100 mm/month in February was recorded three times (1995, 2001 and 2006), and this occurred only 2 times in previous periods (1925 and 1975).","PeriodicalId":15612,"journal":{"name":"Journal of ecotechnology research","volume":"3 1","pages":"27-31"},"PeriodicalIF":0.0,"publicationDate":"2010-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90328212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
