In this study, granulated sludge synthesized in a sequence batch reactor (SBR) and then granulated sludge was transferred to continuous feeding and intermittent discharge (CFID) bioreactor. Two independent variables (air flow rate and hydraulic retention time (HRT)) were considered to optimize the process. Subsequently, long term performance (150 days) of the bioreactor was assessed by monitori...
objective about 1 % of infants are of very low birth weight. however, they comprise about 50% of infant mortality. we compare the effects of continuous versus intermittent feeding on physical growth, gastrointestinal tolerance and macronutrient retention in low birth weight infants (methods a prospective randomized trial clinical trial was performed from 2004-2005. very low birth weight neonate...

Background and purpose: CO2 is the main cause of greenhouse effect. Previous studies have shown that CO2 in methane and coal flue gas can lead to microalgae growth. The aim of this research was to study the CO2 biofixation by Spirulina and injecting kerosene flue gas. Materials and methods: A photo bioreactor was fabricated in which kerosene flue gas and air were separately injected. The ph...
background: Ventilator-Associated pneumonia (VAP) is the second common infections with high mortality (24-40%).In this study designed to determined effect of continuous(infusion) and intermittent(bolus) feeding on the Ventilator-associated Pneumonia in ICU Patient.Methods: This randomized controlled trial was performed on 76 patients admitted in ICU. They were randomly allocated to equal two gr...
introduction the compounds known as β-adrenergic agonists (β-aa) are organic molecules that have the ability to bind to β-adrenergic receptors (β-ar) and start biochemical reactions that will result in increase of accretion of skeletal muscle and reduction in accretion of fat. the anabolic responses to β-aa are temporary, with a peak time occurring during the first 14 days, after which there is...
Background & Aims : About 60% of term infants and 80% of preterm infants are affected by jaundice in the neonatal period which 5-10 % of them require phototherapy. Phototherapy causes the separation of mother and infant, interfering with breastfeeding and there are also some concerns regarding to destruction of the genetic materials. Methods which might reduce the rate of photo would be use...
the objective of this study was to investigate the effects of different levels of amino acid and feeding methods on performance and immune system of broiler chickens. experimental design was based on completely randomized design in a factorial arrangement with 3 feeding methods [control (ad libitum feed intake), intermittent feeding (if) and continuous feed withdrawal (fw)), and 2 amino acid le...
