background: nasal intermittent positive pressure ventilation (nippv) is a non-invasive ventilatory mode, which delivers mechanical ventilation via nasal tubes or prongs. the present study was conducted to compare the efficacy of nippv and nasal continuous positive airway pressure ventilation (ncpap) in reducing the need for intubation in preterm infants with respiratory distress syndrome (rds)....

20 Orogastric tube feeding is indicated for neonates with impaired ability to ingest, and can 21 be administered by intermittent bolus or continuous schedule. Our aim was to determine 22 whether feeding modalities affect muscle protein deposition and to identify mechanisms 23 involved. Neonatal pigs were overnight fasted (FAS) or fed the same amount of food 24 continuously (CON) or intermittent...

Industrial and experimental induction furnaces are used for melting various types of iron ingots, returned scraps and DRI sponge pellets to produce high purity cast - iron and steel heats. The lowest consumption of electrical energy determined for continuous feeding operation is 0.3 KWH/Kg for the production of cast - iron in a 1.5 - ton industrial furnace and 0.45 KWH/Kg for the production of ...

The effect of light regime and feeding system on broiler performance, carcass traits, serum hormones and metabolic profiles was studied using eight hundred and ten one-day-old broiler chicks from Arbor Acres strain. Broilers were distributed randomly in 3 by 3 factorial arrangement. Three light regimes, (continuous light (23L: 1D), constant light (15L: 9D) and intermittent light (4L: 8D)) were ...

Two species of microalgae growing as immobilized and free-cells were compared to test its ability to remove N and P in batch cultures of urban wastewater. The best microalgae-cell growth configuration was selected to be tested in bioreactor operated in semi-continuous mode. Scenedesmus obliquus showed a higher N and P uptake rate in urban wastewater than Chlorella vulgaris. When tested in semi-...

Continuous production of nisin in laboratory media and whey permeate was investigated using a packed-bed bioreactor. Lactococcus lactis subsp. lactis ATCC 11454 was immobilized by natural attachment to fibre surfaces and entrapment in the void volume within spiral wound fibrous matrix. The inoculated bioreactor was fed M17 medium and effect of pH, temperature, dilution rate, and substrate conce...

Ventilator-associated pneumonia (VAP) is a common cause of morbidity in critically ill patients. Appropriate enteral feeding is the most important factor associated with the prevention of VAP. However, the standardization of enteral feeding methods needs clarification. The purpose of this systematic review was to synthesize the factors associated with enteral feeding in order to prevent VAP and...

Immobilized cell reactor of the bacterium Corynebacterium glutamicum entrapped into carrageenan gel beads was constructed and used for the investigation of batch, fed-batch and continuous production of L-glutamic acid from nutritionally enriched sugarcane molasses. High final L-glutamic acid concentration (>93 g l ) was achieved, in batch fermentation, but with low productivity of 3.8 g l h . R...
