Studies into the separation of the component metals of chrome residue [PDF]

, 1991
Chrome residue, the disposal product of a chrome ore pyrometallurgical extraction process, contains a number of valuable metals in oxide form. The bulk extraction of the main metals in residue is investigated by acid dissolution, followed by solvent ...

Efeito da concentração de coagulantes e do pH da solução na turbidez da água, em recirculação, utilizada no processamento dos frutos do cafeeiro Effects from the concentration of coagulants and pH solution on the turbidity of the recirculating water used in the coffee cherry processing

Engenharia Agrícola, 2007
Com o objetivo de determinar a dose e a faixa de pH dos coagulantes sulfato de alumínio (SA), sulfato ferroso clorado (SFC), cloreto férrico (CF) e extrato de semente de moringa (ESM), que proporcionassem maior eficiência na remoção da turbidez na água ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Can inorganic fertilizer substitute for organic amendments in the rehabilitation of saline, sodic ore refining residues?

, 2003
Organic amendments would generally be attractive additions for revegetation of ore refining residues that mostly contain negligible organic matter. However organic materials may not be available on mine sites in sufficient quantities and are bulky to ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Impacts of amending bauxite residue sands with residue fines for the establishment of vegetation on residue disposal areas

, 2009
Long term storage of bauxite residue materials requires a capping stratum which will limit erosion while stabilizing slopes, limit deep infiltration of water into storage piles, and be aesthetically acceptable to the surrounding community.

Espaçamentos entre plantas e cobertura do solo com cama-de-frango na produção da bardana (Arctium lappa L.) Spacing among plants and soil covering with poultry litter in burdock (Arctium lappa L.) production

Revista Brasileira de Plantas Medicinais, 2010
O objetivo do trabalho foi estudar o crescimento, o desenvolvimento e a produção da bardana em resposta a cinco espaçamentos entre plantas (40,0; 47,5; 55,0; 62,5 e 70,0 cm) e ao uso (CCF) ou não (SCF) de cobertura de solo com cama-de-frango ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Effect of vetch wheat mixture and broccoli as preceding crops on organic summer vegetables: on farm trial in western Turkey

, 2011
Organic farming requires the use of practices such as crop rotation, green manure and compost application instead of chemical compounds to enhance farm productivity.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

FEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified
