Research ArticleOpen accessEvery word in the titleEffect of Acidity on Delta 7 Stigmastenol Content of Palestinian Olive OilJihad M. Quasem, Ibrahim Abdullah Afaneh, Harbi T. Al-Masri et al.Olive oil quality is a term influenced by many factors. Δ7 Stigmastenol is a new criteria used to determine olive oil quality especially its purity from adulteration with other types of seeds oil. Δ7 Stigmastenol-acidity correlation were investigated through studying the effect of the literature’s highlighted factors, namely; Olive fly infection, the land topographic and the preservation of olive before … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 7 Nov 2012 · 7,332 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDietary Effects of Magnesium on Histamine Metabolism and Urine Acidity in Domestic FelinesSarah K. Martin, David L. Harmon, Charlotte E. Conway et al.Magnesium deficiency has been associated with increased histamine production in rats. Limitation of Mg with acidifying foods is common practice for management of urinary tract health in domestic cats. Nine healthy adult female shorthair cats were used in a 3 period random crossover experiment with fixed treatment sequences to test the effects of dietary Mg (0.06, 0.12 and 0.18% DM) … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 4 · 29 Dec 2012 · 8,161 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalysis of the Impact of Acidity and Alkalinity on the Microbial Community Structure in Urban RiversDongmei Shen, Cairui Yu, Xinwei Song et al.To address the impact of low-temperature pH on the microbial community structure of river sediment in urban rivers during winter, the sediment of the Pi River was sampled to investigate. Four experimental samples were designed by varying the pH to 5.0, 7.0, and 8.5 based on the original sample (pH = 5.5) and the characteristics of the microbial community were … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 3 · 8 Aug 2023 · 4,959 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInfluence of Brewing Methods and Saccharomyces Cerevisiae on the Aroma and Quality of Shuanghong Vitis Amurensis WineXiaochun Yu, Jing Xu, Zixuan Wang et al.Blending wines is a useful practice in red wine production, however, it is rarely used in Vitis amurensis wine. In recent years there has been a tendency to seek new products from the blending of wines to achieve greater complexity. The purpose of this study was to improve the aroma composition and complexity of Shuanghong V. amurensis wine, enhance its … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 3 · 29 Sep 2023 · 4,974 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExperimental Study on the Microbial Community Structure of the Sediment of Pi River under the Different pH in WinterCairui Yu, Dongmei Shen, Wanfeng Wang et al.In order to solve the poor self-purification ability of low temperature water in winter, the microbial community structure in the sediment of Pi River water (located in West Anhui) was investigated experimentally in this study. Firstly, the sediment was sampled in the lower reaches of Pi River and prepared with the different pH (5.0, 5.5, 7.0 and 8.5); secondly, the … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 15 Mar 2021 · 6,122 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Comparative Assessment of Heavy Metal Pollution in Soil using pH Enrichment Factor and Pollution IndexMichael Nwachukwu, Okoro Uwaezu, Ogbuja I. Ogbuja, Leonard NwosuMany researchers have described pH as heavy metals pollution indicator in soil, but no effort has been made to determine level or quantity of heavy metals that could be indicated by pH. This study measured in-situ soil pH values at Nekede motor mechanic village against the natural background values. We used readings obtained to compute pH enrichment factor (pHeF) at … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Apr 2017 · 7,974 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInfluence of Chemical Properties on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: It is important to investigate the seriousness of degradation of peat swamp forest caused by skidding system in terms of its function as a carbon sink. In this study, we formulated assumptions that conditions of our research site before the introduction of skidding system were in their natural states, thus that changes measured are clearly caused by skidding … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 7,915 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEffect of Precipitation Fluctuation on Soil Carbon Storage of a Tropical Peat Swamp ForestAnton Eko Satrio, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: It is important to compare the effect of extremely different rainfall conditions on soil carbon storage of lowland tropical peat swamp forest. Therefore, under these natural rainfall gradient, the objectives of this study were to determine whether rainfall affects soil carbon storage of a tropical peat swamp forest and to determine what correlations between variables occurs which stimulate … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 8,603 accessesView PDFCite
Research ArticleOpen accessIn the keywordsComparison of Selected Chemical Properties of Peat Swamp Soil Before and After Timber HarvestingMuhamad Ismawi Salimin, Seca Gandaseca, Osumanu Haruna Ahmed, Nik Muhamad Ab. MajidProblem statement: Peat swamp is an important component of the world’s wetlands. Once they are disturbed the tendency for the soil degradation is very high. This study compared selected chemical properties of a peat swamp soil before and after timber harvesting. Approach: Peat soil samples were taken at 0-15 cm depth in 6 plots with 0.1 ha each plot at … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 8,786 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhosphorus Availability Modulates Bradyrhizobium japonicum’s Impact on Soil Micribial Biomass and Soybean (Glycine max (L.) Merrill) Yield in Lubumbashi Tropical SoilsBen Tshibuyi Kasu-Bandi et al.Tropical soils in sub-Saharan Africa exhibit low fertility, high acidity, and limited Phosphorus (P) availability, a key nutrient for agricultural productivity and the sustainability of cropping systems. This deficiency, exacerbated by the strong fixation of P in acidic soils, not only limits plant growth but also the efficiency of the nitrogen-fixing symbiosis between soybeans (Glycine max (L.) Merrill) and Bradyrhizobium … …American Journal of Agricultural and Biological Sciences, Vol. 21, Issue 1 · 13 May 2026 · 1,980 accessesView PDFCite
