Oil-Polluted Water Treatment Using Nano Size Bagasse Optimized- Isotherm Study

The preliminary studies were conducted in order to evaluate the ability and behavior of sugarcane bagasse (generated as waste material from sugar mill) to remove oil by-products from aqueous. In this work adsorption experiments were carried out in a batch reactor to obtain adsorption isotherms of oil by-product on sugarcane bagasse. The capacity of sugarcane bagasse to adsorb oil by-product from aqueous solutions was evaluated at different pH, adsorbent dose and initial concentration. Equilibrium isotherms were analyzed by Langmuir isotherm equations. Compare the result and Langmuir isotherm shown that adsorption of oil by-product on a sugarcane bagasse is favorable. The concentration which was reviewed in this study was much closed to concentration in the industrial water disposal effluents and Langmuir isotherm did describe well the adsorption behavior obtained for these systems

RRR (Reclamation, Remediation and Recovery): Green Phases of Mining and Drilling Lifecycle Influence on and/or Influenced by Sustainable Development

Today industries play comprehensive role in modern and developed societies. Pollution and wastes as output of these processes- here: mine and drilling - are important concerns of both environmental authorities and managers. Recently green studies are favored as a key factor in environmental management systems. It can also be served as a study field in sustainable development. One environmentally-concerned phase of industries is closure and abandonment of mine and well when permanent environmental impacts must be dealt with. Reclamation and/or rehabilitation of mined and drilled lands not only can decrease environmental problems but also can establish environment-friendly conditions having substantial benefits. Wastes can be lowered or even eliminated by being returned into source or by remediation and reuse processes. Circumstantially in mining, the mined land can approach post-mining land uses such as recreational, residential and agricultural uses. These make losses and disadvantages to turn into benefit and advantage. In terms of drilling, practices like subsurface injection can procure demanding disposal. Post closure acts are the long-term phases of industries which should integrate well-designed engineering, management and monitoring to bring about the aimed results and to comply with the environmental management systems

Supplementation of dietary apple cider vinegar as an organic acidifier on the growth performance, digestive enzymes and mucosal immunity of green terror (Andinoacara rivulatus)

The present study was designed to investigate the effects of dietary apple cider vinegar (ACV) on digestive enzyme activity and growth performance as well as immune responses and antibacterial activity of skin mucus in green terror (Andinoacara rivulatus). Fish were fed diets supplemented with 0%, 1%, 2% and 4% of ACV (40.830 ppm acetic acid concentration) for 63 days. The final weight and weight gain values were observed to be significantly higher in fish fed with 2% of ACV compared to the control group (p .05). ACV treatment resulted in a significant increase in the intestinal protease, α‐amylase, lipase and alkaline phosphatase activities compared to control (p < .05). The activities of digestive enzymes in fish fed with 2% and 4% of ACV diets were significantly higher than the other groups (p < .05). The total protein content, alternative haemolytic complement, alkaline phosphatase, total immunoglobulins and lysozyme activities of skin mucus increased significantly in fish fed with ACV diets (p < .05). In conclusion, administration of ACV enhanced digestive enzyme activity, growth performance, immune responses and the immune properties of skin mucus, and it can be used as a natural growth promoter and immunostimulant in green terror culture

Structural Controls of Polymetal Mineralization in North Kashmar, Iran

Abs tract: The North part of Kashmar is located about 250 Km Southwest of M ashhad, Northeast Iran. It is part of the structural Darouneh fault zone and contains rhyolitic, andesitic, pyroclas t ic a n d lava flows . Based on results obtained fro m A F M and Miyashiro diagrams the igneous rocks class ified as a s ubalkaline and calcalkaline. From the data obtained the Ka s h mar strike-slip fault geometry (dis tribution of s hear fractures s uc h a s R,Ró ,P s urfaces , Riedel structures ) plays an important role in controlling the location and emplacement of polymetal mineralization of cop per, lead and zinc ore depos its . The Rie del structure which was obs erved along the northern border of Darouneh fault in d ic a t es a top-west sense of motion. Similar s tructures were obs erved along the southern border o f T a n o u rcheh fault as well. In alterated regions along R, Ró and P surfaces , intrus ion of plutonic roc ks into volcanic rocks have caus ed the develop me n t o f p ropylytic, argillic and s ilis ic hydrothermal alteration, hos ting copper, gold, lead and zinc ore depos its . To s how that the obs erved s hear fracture s urfaces are indeed not significantly different from class ical Riedel s hear pattern a fractal analys is has been done to compare field obs ervations and class ical Riedel s hear pattern. The result shows that the estimated fractal dimens ion for s chematic Riedel is about 1.17, which is in agreement with fra c tal dimens ion of field measurement

Review Article Biological Activities and Pharmacokinetics of Praeruptorins from Peucedanum Species: A Systematic Review

Praeruptorins belonging to the angular-type pyranocoumarins are bioactive constituents that have been isolated from some Peucedanum species such as P. praeruptorum, which is used in traditional Chinese medicine for treatment of cold, cough, upper respiratory infections, and so forth. Many reports have demonstrated that the beneficial pharmacological effects of P. praeruptorum root on cardiovascular, pulmonary, immune, and nervous system diseases were attributed to the presence of praeruptorins. The aim of this review is to explain the recent efforts of scientists in pharmacological screening of natural and synthetic praeruptorin derivatives, studying the mechanisms of some praeruptorins action, pharmacokinetics, toxicity, and relevant structure-activity relationships. Based on reported data about the pharmacological properties of praeruptorins and semisynthetic derivatives of them, it is hopeful that in the near future more studies focus on the discovery of the new application and therapeutic uses of these bioactive compounds and understanding the specific mechanisms of them. The present discusses the reports on molecular and biological activities of praeruptorins of the genus Peucedanum, from 1976 onwards

Effects of waterborne ZnO nanoparticles and Zn2+ions on the gills of rainbow trout (Oncorhynchus mykiss): Bioaccumulation, histopathological and ultrastructural changes

The aim of this study was comparing the toxic effects of zinc oxide nanoparticles (ZnO NPs) versus zinc ions (Zn2+) at a high non-lethal (500μg/L) and a low environmental relevant (0.05μg/L) concentrations on gills of rainbow trout (Oncorhynchus mykiss) following 14 days of waterborne exposure. Structural alterations, histopathological anomalies, and zinc bioaccumulation were investigated in the gills using field emission scanning electron microscopy (FESEM), hematoxylin and eosin staining (H&amp;E), and graphite furnace atomic absorption spectrophotometry (GFAAS) respectively. Some damages such as shortening and fusion of secondary lamellae, surface epithelium hypertrophy, and hyperplasia of the primary lamellae were observed in the gill tissue. Histopathological alterations of gills were minimum in both 659777250 exposed (control) fish and fish exposed to 0.05μg/L Zn2+. The severity of gill damages were higher in fish exposed to 500μg/L ZnO NPs compared to 500μg/L Zn2+and 0.05μg/L ZnO NPs. The Zn accumulation in the gills was concentration-dependent such that bioaccumulation order was as 500μg/L Zn2+&gt; 500μg/L ZnO NPs � 0.05μg/L Zn2+&gt; 0.05μg/L ZnO NPs&gt; control. In summary, the results of present study showed that although the accumulation capability of Zn2+was higher than ZnO NPs, but NPs cause more structural damages to gills compare to ions. © 2018, Central Fisheries Research Inst.
