The technologies of treating acid mine drainage (AMD) commonly include active and passive treatment. The coating technology can enhance the removal performance of some low-cost adsorbents. This study adopted Langmuir and Freundlich isotherm to fit the batch experimental dates. The results show that the Qmax of coated bone char could increase 78.83 times than uncoated bone char. However, the coa...

Since the appearing probability of each English symbol P (a), ...P (b), ...P (” ”), ..., P (; ) is not uniform, we should be able to reduce the number of required bits. Based on the probability of each English symbol, we can compute the entropy H(E) ∼= 4.5 bits / char. If we use Huffman coding taught in this lecture to encode English keyboard, then we only need around 4.7 bits / char. Furthermo...

The trophic ecology (diet and headmorphology) andmigration patterns of two closely related salmonid fishes, Arctic char (Salvelinus alpinus (L., 1758)) and Dolly Varden (Salvelinus malma (Walbaum, 1792)), were examined in tributaries of Lake Aleknagik, southwestern Alaska, to test for differentiation between species. Schoener’s index of proportional overlap andmultivariate analyses of diets sug...

It has been observed that certain char particles shrink when oxidized under kinetically limited conditions, instead of reacting at constant diameter, as expected. This study was perfonned to determine whether or not char from PSOC 1451 coal, prepared at different temperatures would also shrink during low temperature gasification. Coal chars, formed at l 200K and 1600K, were levitated in the ele...

Carbonization is a kind of pyrolysis process to produce char from organic materials under an inert atmosphere. In this work, chars derived from various solid wastes were characterized from the standpoint of fuel recovery and pretreatment of waste before landfilling. Sixteen kinds of municipal and industrial solid wastes such as residential combustible wastes, non-combustible wastes, bulky waste...

The successful migration of euryhaline teleost fish from freshwater to seawater requires the upregulation of gill Na+-K+-ATPase, an ion transport enzyme located in the basolateral membrane (BLM) of gill chloride cells. Following 39 days of seawater exposure, Arctic char had similar plasma sodium and chloride levels as individuals maintained in freshwater, indicating they had successfully acclim...

In this work, a bio-based flame retardant (Cy-HEDP) was synthesized from cytosine and HEDP through facile salt-forming reaction embedded into epoxy matrix to improve the retardancy smoke suppression performance. The product Cy-HEDP well characterized by FTIR, 1 H 31P NMR SEM tests. On basis of results, adding 15 wt% Cy-HEDP, EP15 can pass UL-94 V-0 rating, total production (TSP) as heat release...

We report on the construction of a linkage map for brown trout (Salmo trutta) and its comparison with those of other tetraploid-derivative fish in the family Salmonidae, including Atlantic salmon (Salmo salar), rainbow trout (Oncorhynchus mykiss), and Arctic char (Salvelinus alpinus). Overall, we identified 37 linkage groups (2n = 80) from the analysis of 288 microsatellite polymorphisms, 13 al...

This paper reports the pyrolytic treatment of granulated scrap tires (GST) in a pilot distillation unit at moderate temperature (550°C) and atmospheric pressure, to produce oil, char and gas products. Tire-derived oil is a complex mixture of organic C(5)-C(24) compounds, including a very large proportion of aromatic compounds. This oil has a high gross calorific value (∼ 43 MJ kg(-1)) and N and...
