The influence of feed size and pulp density on the specific rate of breakage of quartz was investigated. Plots of log fraction of feed remaining within the feed size interval against grinding time allowed the application of the first order grinding model to be examined. Substantial non-linearities were observed for all feed sizes due to environmental and material factors. For feed sizes above 1...

The renal protective effect of an active principle isolated from the aqueous extract of fruit pulp of Eugenia jambolana was investigated in streptozotocin (45 mg/kg body weight)-induced severely diabetic rats (FBG > or = 300 mg/dl). For isolation of active principle, crude aqueous extract of E. jambolana fruit pulp was subjected to purification by ion-exchange column chromatography, which yield...

OBJECTIVE The aim of this study was to evaluate the tissue dissolution efficacy of four root canal irrigation solutions (sodium hypochlorite [NaOCl], chlorhexidine gluconate [CHX], Octenidine [OCT], and QMix 2in1) on bovine pulp tissue. MATERIALS AND METHODS Fifty bovine pulp tissue samples, each weighing 6.55 mg, were prepared and randomly divided into four experimental groups and one contro...

this experiment was conducted to evaluate the effects of different levels of dried lemon pulp (dlp) on performance, carcass traits, blood biochemical and immunity parameters of broilers. in this experiment 240 of broilers (ross-308) were used in a completely randomized design with 4 treatments and 3 replicates (with 20 birds in each replicate) from 1 to 42 days. experimental diets included: 1) ...

the effect feeding olive-pulp silage (ops) for 120 days on several blood attributes was studied using 16 rams allotted to two diets consisting of 70% corn silage or 70% ops. olive-pulp silage feeding resulted in lower serum total protein, alanine aminotransferase, calcium and phosphorus levels and higher glucose concentration compared to the corn silage diet. body weight and other blood attribu...

Pulp properties are key factors to assessing the performance of a refining process, evaluating operational conditions, and optimizing the process of stock preparation. This paper presents a data-driven approach to estimate the beating degree and wet weight of pulp after refining using case-based reasoning (CBR). Historical data generated in a refining process at a paper mill was used to evaluat...

Some feedstuffs containing significant levels of fiber may be a good source of bioactive compounds that may contribute to improving broiler meat quality. However, high fiber level can have a negative impact on broiler performance. A study was undertaken to investigate the impact of incorporating citrus pulp (5 or 10%) or dehydrated pasture (5 or 10%) on the performance, carcass yield, and chara...

enzymatic deinking of xerox printed papers by commercial cellulase from aspergillus niger fungi was investigated. enzymatic treatment was done under constant condition of 0.1 percent enzyme based on oven-dried weight of pulp (102 unit per 100 gram oven-dried pulp), 15 min. treatment time, in four ph levels as 4, 5.7, 8 and 9. then, the effect of ph variation on the appearance and strength prope...

With an annual production of some 3.5 million tons between 1990 and 1995, dissolving wood pulp accounts for only 2% of the total wood pulp production. However, the high demands for cellulose purity and reactivity as well as its manifold routes of utilization are the reason for the advanced state of technology within the pulp industry. For dissolving pulp production, only acid sulfite and prehyd...
