A pilot-scale engineered ecosystem (PSEE) operated for over 2 years in sub-tropical conditions, produced an effluent with COD (median 38 mg/L) and TSS (median 3mg/L) levels comparable to that required by the AS/NZS 1547:2000 Onsite Domestic Wastewater Management standard. Only partial nitrification was achieved as dissimilatory nitrate reduction to ammonia occurred; however the level of NH(4)-N...

Legumes have developed a unique way to interact with bacteria: in addition to preventing infection from pathogenic bacteria like any other plant, legumes also developed a mutualistic symbiotic relationship with one gender of soil bacteria: rhizobium. This interaction leads to the development of a new root organ, the nodule, where the differentiated bacteria fix for the plant the atmospheric din...

The sources and rates of metabolic acid production in relation to renal net acid excretion and thus acid balance in humans have remained controversial. The techniques and possible errors in these measurements are reviewed, as is the relationship of charge balance to acid balance. The results demonstrate that when acid production is experimentally increased among healthy subjects, renal net acid...

The present work aimed at quantifying nitrogen (N) and amino acid (AA) fluxes in the digestive tract of growing pigs fed a casein diet. In this paper we report on digesta passage at the terminal ileum, on apparent balances at the ileal and faecal levels, and on nutrients appearance in the portal vein. Digesta flow-rate at the terminal ileum was maximum between 6 and 12 h after the meal. About 1...

ASSET LEVELS GROWING: In 2011, there was $12.4 billion in health savings accounts (HSAs) and health reimbursement arrangements (HRAs), spread across 8.4 million accounts, according to data from the 2011 EBRI/MGA Consumer Engagement in Health Care Survey, sponsored by EBRI and Matthew Greenwald & Associates. This is up from 2006, when there were 1.3 million accounts with $873.4 million in assets...
