Physiological effects of copper on the freshwater alga Closterium ehrenbergii Meneghini (Conjugatophyceae) and its potential use in toxicity assessments
Although green algae of the genus Closterium are considered ideal models for testing toxicity in aquatic ecosystems, little data about the effects of toxicity on these algal species is currently available. Here, Closterium ehrenbergii was used to assess the acute toxicity of copper (Cu). The median effective concentration (EC50) of copper sulfate based on a dose response curve was 0.202 mg L, a...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...
15 صفحه اولFatty Acid Profile and Hydrocarbon Characterization of Nitzschia Closterium (w.sm.)
Lipid productivity is a critical variable for evaluating algal species for biodiesel production. The pennate diatom Nitzschia closterium (W. Sm.) isolated from the local water body of Madurai was cultivated in four different media (WCg, Csi, F/2 and Diatom medium) and screened for the presence of neutral lipid content using Nile red fluorescent dye. The relative abundance of lipid content was e...
متن کاملSynthesis of Organic Nitrogen and Chlorophyll by Nitzschia Closterium
When cells of Chlorella are grown in a medium containing a limiting quantity of nitrate or ammonia as nitrogen source, photosynthesis and cell division continue after all the available nitrogen in the medium has been abstracted by the growing plants. The cells become nitrogen-deficient. When kept in darkness with added nitrate these nitrogen-deficient cells synthesize a considerable quantity of...
