Résumé :

Treating peat with nutrient-rich ash significantly increases the content of different nutrients in the substrate. Such ash treatment promotes the revegetation of abandoned extracted peatlands. The aim of this study is to analyze the effect of wood ash (WA15 = 15 t ha−1 and WA10 = 10 t ha−1), oil shale ash (OSA8 = 8 t ha−1), and a mixture of wood ash and oil shale ash (WA10 + OSA8) on the revegetation (vascular plants and bryophytes) of the Puhatu abandoned extracted peatland in NE Estonia. The following results were obtained: (1) The MRPP tests indicate that there are compositional differences

Wood ash may be used to mitigate soil acidity and improve crop production. We compared effects of wood ash and recommended fertilizers on soil properties of a Gray Luivsol, crop yields and contribution margins in southeast Peace, Alberta, Canada. The CHK (no fertilizer, inoculation or wood ash), FRT (recommended fertilizers or inoculation), ASH (wood ash rate to supply amounts of phosphorus equivalent to the FRT treatment); and ASH+N (same as ASH + N fertilizer or inoculation) treatments were applied in 2006 and 2007. Their effects were studied from 2006 to 2014. Wood ash had all the

Résumé :

Acid mine drainage (AMD) is formed because rocks containing sulfide minerals, such as pyrite (FeS?), are exposed to oxygen and water. AMD treatment is generally carried out with lime, but this method is relatively expensive and unsustainable. Fly ash-bottom ash (FABA), a type of coal combustion waste can potentially replace lime in treating acid mine drainage (AMD). This study aimed to elucidate the potential use of FABA to neutralize pH of AMD. The method used was a floating FABA system using styrofoam with three treatments: floating FABA with dimensions (cm length x cm width x cm height) of

Résumé :

A pilot study on the feasibility of using high carbon wood ash to control composting odor emissions was conducted at a green material composting facility. The study's treatments consisted of adding 0%, 12.5%, and 25% high carbon wood ash by volume to green material compost feedstock in three separate windrows. The wood ash has properties similar to activated carbon with an active surface area of 105 square metres per gram on a dry weight basis. The odorant emission data suggest that the higher percentage wood ash treatment results in the most effective control of most compost odors and that wo

Résumé :

Spent activated carbon (SAC) usually exhibits a low specific surface area due to its high ash contents. In this study, pre-treatments, such as heat and acid treatments, were optimized to improve this feature. The heat pre-treatment did not reduce the ash content, nor did it increase the surface area. Because metallic ions adsorbed in SACs turn into ash upon the heat treatment. In the acid pre-treatment, the volatiles and fixed carbon were increased with decreasing ash contents. In this study, it was found that the surface area increase was correlated with the ratio between fixed carbon and ash

Résumé :

Fly ash from power plants is very toxic because it contains heavy metals. In this study fly ash was treated with a thermal plasma. Before their treatment, the fly ash was analyzed by many technics such as X-ray fluorescence, CHN elemental analysis, inductively coupled plasma atomic emission spectroscopy and scanning electron microscopy. With these technics, the composition, the chemical and physical proprieties of fly ash are determined. The results obtained by these analysis show that fly ash is mainly composed of carbon, and it contains also sulfur and metals such as V, Ca, Mg, Na, Fe, Ni, a

Résumé :

Fly ash and AMD samples were characterised by standard analytical methods for selection of the test materials. Active treatment by means of mixing fly ash with AMD in beakers and a large tank at pre-determined ratios have shown that fly ash is capable of neutralising AMD and increasing the pH beyond neutral values, which optimises the removal of heavy metals and ions. The trend was: the more fly ash added the quicker was the reaction time and higher the pH values achieved. Iron was reduced by as much 99 % in beaker scale experiments via Fe(OH)3 precipitation at pH values &gt 4.0. A 99 %

Philosophiae Doctor - PhD Mine water poses a serious environmental challenge and contains elements such as Fe, Al, and Mn in potentially toxic concentrations. The major anion in mine water is sulphate. The complexity and diversity of mine water composition makes its treatment very expensive, and there is no “one-fits-all” treatment option available for mine water. Active treatment of mine water produces water with good quality but the processes are not sustainable because of the costs. Previous studies have shown that acid mine drainage can be treated with coal FA to produce better quality

Résumé :

The objectives of this study were to determine the effects of recombinant bovine somatotropin (bST) and added dietary rumen undegradable protein (RUP) on organ and tissue weights and body composition in growing dairy heifers. A total of 32 Holstein heifers, 3 months of age at the beginning of the study were used in the experiment. Eight heifers were slaughtered at 3 mo of age to determine pre- treatment body composition. The remaining heifers were randomly assigned to treatments (n=6) consisting of 0.1 mg/kg body weight per day of bST and 2% added dietary RUP (dry matter basis) applied in a 2X

Résumé :

The US Army Corps of Engineers (USACE) is responsible for stewardship of approximately 12.5 million acres across the United States. USACE’s Environmental Stewardship program mission is to protect, preserve, and restore significant ecological resources on USACE project lands. Since the early 2000s, non-native and invasive Emerald Ash Borer (EAB) has killed hundreds of millions of ash trees in the US, becoming the most destructive and costly invasive forest insect in North America. This research effort estimates the cost of managing EAB damage to USACE projects including treatment, removal, or r

Résumé :

Development projects have a wider set of impacts than just direct project outputs. A hydropower dam, for example, produces electricity but also disrupts river flows and may affect biodiversity and the general aquatic environment. A new port development may affect coastal resources such as mangroves and coral reefs. Coal-fired power plants affect both the local and the global environments through emissions of ash and dust (affecting mostly the local environment) as well as greenhouse gases (affecting the global environment). Sewage and sanitation projects provide new services to consumers but a

The clinical manifestations are light brown or dark brown patches symmetrically distributed on the cheeks, forehead and mandibular with different shades and unclear borders. Melasma particularly affects women during menstruation, especially in thirties and forties Asian women. The incidence of Asian women of childbearing age is as high as 30%. Current treatments for melasma include topical drugs, c
