Applied and Environmental Soil Science, Volume 2011, Issue 1, 2011., 2011 The liquid sewage sludge (LSS) was applied on a field experiment during four years at successive applications to evaluate the changes in soil attributes and on Surinam grass (Brachiaria decumbens) uptake of nutrients. A randomized blocks experimental design, with two treatments (with and without LSS) and three repetitions, was used. Land application of

Redução de cromo hexavalente por bactérias isoladas de solos contaminados com cromo [PDF]
Ciência Rural, 2007 A redução do Cr(VI) para Cr(III) diminui a toxidade deste metal no ambiente, uma vez que o Cr(III) é insolúvel às membranas biológicas. Assim, a redução microbiana do Cr(VI) é uma alternativa para reduzir os impactos ambientais causados por este metal, utilizado em diversos processos industriais.

Mediators of Inflammation, Volume 6, Issue 5-6, Page 369-374, 1997., 1997 Anti‐inflammatory actions of two anti‐allergic drugs, alone or with dexamethasone (Dex) were examined in two models, because inflammation is claimed to be important for allergic events, especially for asthma. Cromoglycate and nedocromil were tested in ischaemic‐ and histamineinduced paw oedema models of mice. These antiallergic drugs (1–100 mg/kg, i.p.)

NSAIDs in the Treatment of Adult Asthma: Sodium Cromoglycate and Nedocromil Sodium
Canadian Respiratory Journal, Volume 2, Issue A, Page 19A-23A, 1995., 1995 Among nonsteroidal anti‐inflammatory drugs used in the treatment of adult asthma, sodium cromoglycate and nedocromil sodium are the most frequently prescribed. These medications have a similar efficacy profile in asthma although it has been suggested that nedocromil is more powerful than cromoglycate, particularly in its steroid sparing effects.

Winter Baseflow Calibration's Critical Role in Hydrological Modeling for the Pamir Region
Water Resources Research, Volume 62, Issue 1, January 2026.Abstract The Pamir Mountains, a critical water source for Central Asia, require accurate quantification of runoff components for water resource management under climate change. Uncertainties in precipitation data are known to greatly affect hydrological model accuracy, leading to the widespread use of multi‐data calibration methods to avoid internal ...
