Experiments on granule transport and the mean residence time in a rotary horizontal drum with inclined flights showed that the granules can be transported steadily. A model for granule transport based on the analysis of granule motion and other studies on inclined drums was developed to calculate the mean residence time of the granules, and verification experiments under different conditions we...

The pharmacokinetics aspects of levofloxacin were studied in healthy and experimentally renal damaged Muscovy ducks after single intravenous (IV) and oral (PO) dose of 10 mg kg(-1) bwt. Following IV administration, elimination half-life (t 1/2( β )) and mean residence time (MRT) were longer in renal damaged ducks than in healthy ones. Total clearance (Cltot) in renal damaged ducks (0.20 L kg(-1...

[1] Estimates of mean residence time (MRT) are increasingly used as simple summary descriptors of the hydrological processes involving storage and mixing of water within catchment systems. Current understanding of the physical controls on MRT remains limited, and various hypotheses have been proposed to explain its variability between catchments. We present a series of virtual experiments to in...

Evaluating biochars for their persistence in soil under field conditions is an important step towards their implementation for carbon sequestration. Current evaluations might be biased because the vast majority of studies are short-term laboratory incubations of biochars produced in laboratory-scale pyrolyzers. Here our objective was to investigate the stability of a biochar produced with a med...

Pyrogenic carbon (PyC) is an important component of the global soil carbon (C) pool, but its fate, persistence, and loss dynamics in contrasting soils and environments under planted field conditions are poorly understood. To fill this knowledge gap, a 13C-labelled biochar, as a surrogate material for PyC, produced from Eucalyptus saligna by slow pyrolysis (450°C; δ13C -36.7‰) was surface (0-10 ...

Estimates from multilevel regression of 1768 women living in the Paris metropolitan area showed that women who reported concentrating their daily activities in their perceived neighbourhood of residence had a statistically greater likelihood of not having undergone cervical screening during the previous 2 years. Furthermore, the characteristics of the administrative neighbourhood of residence (...

Hydrothermal carbonization (HTC) of lawn grass was carried out at 200 °C and 240 °C for 30 to 180 min. The chemical, energetic, and structural characteristics of HTC solid residues were investigated. Results from HTC experiments indicate that solid mass yield of all solid residues was 31 to 50%. The hydrogen/carbon (H/C) and oxygen/carbon (O/C) atomic ratios of all solid residues were 1.17 to 1...

OBJECTIVES This study analyzed the effect of the number of mosquito nets that are owned by households, dwelling characteristics and maternal demographic characteristics on malaria infections. MATERIAL AND METHODS The 2011 Demographic and Health Survey (DHS) data for children under 5 years of age were used. The children were subjected to haemoglobin test and rapid diagnostic test (RDT) to asce...

STUDY OBJECTIVES To study the association between greenery filled public areas that are nearby a residence and easy to walk in and the longevity of senior citizens in a densely populated, developed megacity. DESIGN Cohort study. METHODS The authors analysed the five year survival of 3144 people born in 1903, 1908, 1913, or 1918 who consented to a follow up survey from the records of registe...

Assessment of risk factors Childhood risk factors were assessed up to 9 years of age: neurodevelopmental characteristics (perinatal insults, gross motor skills, and intelligence quotient); parental characteristics (mother’s internalising symptoms, including depression and anxiety, mother–child interactions, criminal conviction history, and parental disagreement about discipline); family charact...
