Review ArticleOpen accessEvery word in the titleRecent Status of Fishes in the Yangtze River and its Ecological Health AssessmentChun-Jiao Lu, Jin-Jing Duan, Muhammad Junaid et al.The Yangtze River, ranking behind the Nile and the Amazon rivers, is the third longest river in the world. The Three Gorges Dam constructed on the Yangtze River dramatically altered the ecological environment in the surroundings. In this review, we integrated the published data about the Three Gorges Project and systematically analyzed the status of fish population in the Three … …American Journal of Environmental Sciences, Vol. 12, Issue 2 · 4 Apr 2016 · 10,523 accessesView PDFCite
Research ArticleOpen accessEvery word in the title4D N = 1 Supersymmetric Yang-Mills Theories on Kahler-Ricci SolitonBobby Eka GunaraIn this study we consider four dimensional N = 1 supersymmetric gauge Yang-Mills theory whose complex scalar manifold is Kahler and deforms with respect to a real parameter. The deformation of the geometry is governed by Kahler-Ricci flow equation. This setup implies that some couplings such as shifting quantities, momentum maps and the scalar potential turn out to be evolved … …Journal of Mathematics and Statistics, Vol. 8, Issue 4 · 2 Jan 2013 · 6,640 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Impact of Anthropogenic Activities Recorded By Mercury in the Sediment from Dianshan LakeHui Zhang, Nan Zhang, Qi Yang et al.The mercury in sediment cores from Dianshan Lake, Shanghai is studied in this study and it indicates that the mercury level changing from 52.78-145.66 µg kg-1 in sediment can be obviously divided into three sections responding to the development of economy of Shanghai. Mercury decreases with depth in 0-11 cm underground, which is corresponding to the depositing period after 1980; … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 4 Aug 2012 · 7,018 accessesView PDFCite
Research ArticleOpen accessIn the keywordsTranslation Quality Assessment of Online Translation Systems in Translating English to Thai on Phuket TourismKitsiri Chochiang, Thanakrit Thongkhamdee, Lalita SathansatThis research aims to compare four English-to-Thai translator applications on translating the comments posted on social media. Four translator applications include Google Translate, Baidu Translate, Yandex.Translate and Microsoft/Bing Translate. The comments in this study are on three main popular attractions in Phuket, Thailand. The attractions include a temple (Wat Chalong), a viewpoint spot (Promthep Cape) and a beach (Patong beach). … …Journal of Computer Science, Vol. 16, Issue 11 · 10 Nov 2020 · 7,498 accessesView PDFCite
Review ArticleOpen accessIn the keywordsThe Status of Pollutants in the Three Gorges Reservoir Area, China and its Ecological Health AssessmentChun-Jiao Lu, Dan Luo, Muhammad Junaid et al.The Three Gorges Reservoir Area (TGRA) stretches along the Yangtze River from Jiangjin District, Chongqing to Yichang, Hubei in China. Since TGRA is the main source of drinking water and fresh fishery in China for millions of people, both researchers and the government have concerns for environmental pollution and ecological security in the TGRA. This review highlighted the status and … …American Journal of Environmental Sciences, Vol. 12, Issue 5 · 28 Sep 2016 · 7,925 accessesView PDFCite
Research ArticleOpen accessIn the author namesAnalysis on Characteristics of Corn Farmers on Selecting Seeds Under the Seed Subsidy in China: A Case Study in Liaoning and Hebei Provinces, ChinaNing-Ning Sun, Shoichi Ito, Qianhui Gao et al.The Seed Subsidy (SS) is the direct subsidy to encourage farmers cultivate with high quality seeds, which was introduced to nationwide farmers by Chinese government since 2004. China is the second biggest corn producer in the world and the government has provided SS for the corn producers since 2004. As the government allocated an increasing amount of budgets on SS … …American Journal of Economics and Business Administration, Vol. 4, Issue 2 · 22 May 2013 · 7,166 accessesView PDFCite
Research ArticleOpen accessIn the author namesSeasonal Autoregressive Integrated Moving Average Model for Precipitation Time SeriesYan Wang, Xinghua Chang, Meng Gao, Xiyong HouPredicting the trend of precipitation is a difficult task in meteorology and environmental sciences. Statistical approaches from time series analysis provide an alternative way for precipitation prediction. The ARIMA model incorporating seasonal characteristics, which is referred to as seasonal ARIMA model was presented. The time series data is the monthly precipitation data in Yantai, China and the period is from … …Journal of Mathematics and Statistics, Vol. 8, Issue 4 · 20 Feb 2013 · 12,655 accessesView PDFCite
Research ArticleOpen accessIn the author namesEffects of Oak Chip Treatments on Quality of Dry White Wines During AgingRongbin Li, Xiaofang Liang, Chunhua Song et al.The objective of the research was to evaluate the effect of different oak chip treatments on quality of Longyan dry white wine during aging. Phenolic substances, antioxidant activity and Cu2+ reduction force were measured. The results showed that wines treated with French oak chips (6 g/L) had significantly higher contents of total phenols (0.083 mg/mL) and flavonoids (0.063 mg/mL), also … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 26 Feb 2020 · 7,235 accessesView PDFCite
Research ArticleOpen accessIn the author namesExpression and Induction Optimization of Mucor Circinelloides Lipase in Escherichia ColiYueping Yang, Yao Zhang et al.Microbial lipases serve as versatile biocatalysts for modifying lipid substrates, enabling diverse biotechnological applications spanning food technology, renewable energy production, and pharmaceutical sectors. Genomic analysis of Mucor circinelloides WJ11 revealed multiple lipase-encoding genes, with WJ_23 successfully cloned and heterologously expressed in Escherichia coli. Since the lipase expression was mainly concentrated in the cell pellets, appropriate induction strategies had been investigated … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 2 · 13 Jun 2025 · 5,982 accessesView PDFCite
Research ArticleOpen accessIn the author namesIntegrated Analysis of Transcriptomic and Metabolomic Responses in Rice Resisting False SmutYanmin Yu, Haiying Liu, Hongtao Wu et al.Rice false smut, caused by Ustilaginoidea virens, is an important fungal disease that reduces both grain yield and quality. To dissect the molecular basis of resistance, we combined transcriptome sequencing and metabolite profiling in resistant and susceptible rice cultivars. Transcriptome sequencing revealed more than 8,500 genes with altered expression patterns after infection, while metabolite profiling detected over 700 significantly changed … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 27 Aug 2026 · 1,057 accessesView PDFCite
