This paper analyses investment behaviour of family business owners in order to disentangle risk taking patterns in the Spanish context. In particular, this study tries to show whether family business owners are more risk tolerant than no owners, and which features are conditioning risk taking perceptions and behaviour. For that, we use data from the 2002 and 2005 Spanish Survey of Household Fin...

A pilot scale wastewater treatment plant was designed, constructed and operated on site to treat wastewater from a combined effluent drain. The activated sludge process (ASP) was used at three different hydraulic retention times (HRT) of 12, 10 and 8 hrs at an average MLSS concentration of 3500 mg/L. Under each HRT, the pilot plant was operated for a period of 10-12 weeks. Chemical oxygen deman...

The objective of the research is to develop a new, simple, and environmentally friendly method for the simultaneous removal of heavy metals and total organic carbon (TOC) in coproduced water (CW) from the energy production industry. Ferrate anions (FeO4) or Fe(VI) oxidation ability is very strong over the whole pH scale. Fe(VI) has been considered one of the futuregeneration water quality impro...

Em 2005, a Organização Mundial de Saúde revisou e atualizou a classificação dos tumores odontogênicos, e algumas terminologias foram modificadas. Devido à sua natureza neoplásica, o ceratocisto odontogênico, anteriormente classificado como um cisto, teve seu nome alterado para tumor odontogênico ceratocístico (TOC). A prevalência de TOC no seio maxilar é de apenas 1%.1 O TOC possui taxa elevada...

Chloroplast biogenesis often requires a tight orchestration between gene expression (both plastidial and nuclear) and translocation of ~3000 nuclear-encoded proteins into the organelle. Protein translocation is achieved via two multimeric import machineries at the outer (TOC) and inner (TIC) envelope of chloroplast, respectively. Three components constitute the core element of the TOC complex: ...

Crude oil exploration is associated with spillage causing environmental degradation including loss of soil fertility and biodiversity. Various technologies are available for remediating crude polluted soil, but, bioremediation seems to be more environmentally friendly cost effective. Thus, the current work on using cow dung wire croton leave as amendments. It was conducted a batch process monit...

Wastewater from the wood and pulp industry is of environmental concern. It contains high concentrations of organic and inorganic matter. In this work a combined method of coagulation, adsorption and nanofiltration/reverse osmosis (NF/RO) was investigated in the purification of biologically treated wastewater from wood processing. Coagulation with 0.8 g dm(-3) AlCl3 x 6H2O and adsorption on 2.5 ...

Simultaneous nitrification/denitrification and trace organic contaminant (TrOC) removal during wastewater treatment by an integrated anoxic-aerobic MBR was examined. A set of 30 compounds was selected to represent TrOCs that occur ubiquitously in domestic wastewater. The system achieved over 95% total organic carbon (TOC) and over 80% total nitrogen (TN) removal. In addition, 21 of the 30 TrOCs...

Supercritical water oxidation (SCWO) is able to completely mineralize every kind of waste in residence times lower than one minute. Supercritical water oxidation in presence of hydrothermal flames can reduce residence times to the order of milliseconds. The most recalcitrant compounds in terms of difficulty to oxidation for the supercritical water oxidation are acetic acid and ammonia. The obje...
