Lixiviação de nitrogênio em latossolo incubado com lodo de esgoto Nitrogen leaching in a latosol incubated with sewage sludges

Revista Brasileira de Ciência do Solo, 2009
Lodo de esgoto contém teores elevados de N orgânico. Se for aplicado em quantidade excessiva em solos, há risco de poluição de águas subsuperficiais com nitrato, produto da mineralização do N.

Nitrato derivado do suco de beterraba e suas influências no exercício de alta intensidade: uma revisão sistemática de ensaios clínicos randomizados

Revista Brasileira de Nutrição Esportiva, 2022
A suplementação de nitrato (NO3) por meio do suco de beterraba, parece ser eficaz em exercícios de alta intensidade e curta duração, que utilizam primordialmente a via metabólica anaeróbica. A fim de esclarecer tais questões, foi desenvolvida uma revisão

Efeito da homeopatia Ammonium Carbonicum na minimização da lixiviação de nitrato Effect of the homeopathy Ammonium Carbonicum in the minimization of nitrate leaching

Ciência e Agrotecnologia, 2007
Avaliou-se o efeito da solução homeopática Ammonium Carbonicum em duas dinamizações, CH3 e CH30, sobre a lixiviação de NO-3. A hipótese inicial foi a de que essas soluções homeopáticas atuariam na microbiota do solo otimizando a utilização de N pela ...

Emerging Rare Earth Element Separation Technologies

European Journal of Inorganic Chemistry, Volume 27, Issue 25, September 2, 2024.
Lanthanides are crucial components used in clean energy technologies, but their similar chemical and physical properties make separation challenging. This review article explores the use of neutral organic compounds (i. e., extractants and ligands) to effectively separate these vital elements.

Exotic, traditional and hybrid landscapes: The subtle history of the Iberian Peninsula maize between ‘tradition’ and ‘modernity’

PLANTS, PEOPLE, PLANET, Volume 6, Issue 5, Page 1047-1059, September 2024.
Maize is the world's second most important agricultural crop. The cereal was unknown to Europeans before the end of the 15th century, but since its arrival in Europe, it has changed agriculture, food and landscapes. Terraces where maize was cultivated in the Northwest of the Iberian Peninsula contributed to the formation of local cultures and ...

Microbubble‐encapsulated Cobalt Nitrato Complexes for Ultrasound‐triggerable Nitric Oxide Delivery

ChemMedChem, Volume 19, Issue 16, August 19, 2024.
Complexation of cobalt with nitric oxide (NO) is complex and its understanding offers applications in catalysis and biological processes. We evaluated four cobalt nitrato complexes for ultrasound‐triggered release of NO. For future therapeutic evaluation we showed for one complex tolerability in vitro and encapsulation in polymeric microbubbles ...

Structural Trends and Vibrational Analysis of N,N,N′,N′−Tetramethylmalonamide Complexes Across the Lanthanide Series

European Journal of Inorganic Chemistry, Volume 27, Issue 6, February 21, 2024.
Exploring the structural and vibrational properties of N,N,N′,N′−tetramethylmalonamide complexes across the lanthanide series may explain the lanthanide speciation and distribution ratios during liquid‐liquid separations by diamide extractants. Abstract Fundamental understanding of coordination chemistry across the lanthanide series is essential for ...
