In most cases, the anammox process is used for nitrogen removal from reject water coming from dewatering of digested sludge. However, there are more industrial streams suitable for treatment by partial nitritation/anammox process. The landfill leachate may be a good example of such wastewater. Generally, landfilling is the most used solution for treatment of urban solid wastes. The problem with...

In the past few decades, laparoscopic adjustable gastric banding is one of the most common bariatric procedures performed to treat morbid obesity. Device-related complication such as connection-tubing problem is rare. Here we present a case of gastric band tubing complication during pregnancy. This case illustrates the need to maintain high index of suspicion of gastric band device-related comp...

Anammox coupling with nitrate reduction under various electron donors was studied using sludge acclimatized to have anammox and denitrification activities. Due to a deficiency in electron donors for NO(3)(-) reduction, anammox activity in an inorganic medium containing NO(3)(-) and NH(4)(+) was lower than that in NO(2)(-) and NH(4)(+). Anammox could use NO(2)(-) competitively against denitrifie...

Samples from six depths of the Black Sea's suboxic zone were analyzed for 16S rRNA gene sequence information. A gradient in phylotype diversity was found. The distributions of known anaerobic ammonium oxidation (anammox) bacteria, many unknown Planctomycetes, and other phylotypes were examined in relation to the local nutrient and redox conditions.

Proof. The result follows by direct manipulation of the terms. Lemma S2 Suppose that the k×k matrices A and B have bounded spectral norms ‖A‖ ≤ λ and ‖B‖ ≤ λ, for some fixed positive constant λ. Then ∥∥∥Ah −Bh∥∥∥ ≤ hλh−1 ‖A−B‖ , for h = 1, 2, .... (A.1) Proof. We establish this result by backward induction. It is clear that it holds for h = 1. For h = 2, using the identity A −B = A(A−B) + (A−B)...

an experiment was carried out in 2008 to investigate the effects of different irrigation regimes, and chickpea cultivars on chickpea production in the khorramabad lorestan. the experiment was split–plot in a randomized complete block design with 3 replications. supplementary irrigation at 8 levels (1-rainfed without irrigation, 2-irrigation after sowing, 3-irrigation at flowering, 4-irrigation ...

Climate is a complex system which is changing mainly due to the increase of greenhouse gases. Because of the importance of climate change and the effects it can have on water resources, in recent years, this topic has been taken into consideration for different basins on Earth. The objective of this study is to investigate the effects of climate change and forecasting meteorological variables o...

degree, in amyotrophic lateral sclerosis. The possibility that myelotoxic antibodies may be formed secondarily to myelin destruction, arising perhaps from some non-immune cause, is a very real one in view of the finding of antibody to encephalitogenic factor in a variety of neurological conditions reported by Field, Caspary, and Ball (1963). Nevertheless, their undoubted occurrence in multiple ...

Due to its high global warming potential, nitrous oxide (N(2)O) emissions from wastewater treatment processes have recently received a high degree of attention. Nevertheless, there is still a lack of information regarding the microbiological processes leading to N(2)O production. In this study, two lab-scale sequencing batch reactors were operated with deammonification biomass to investigate th...
