An experimental investigation of the cake filtration behaviour of 125-180 pm polyethylene particles, suspended in a neutrally buoyant Newtonian fluid, has been carried out. Static cake filtration measurements of both filtrate volume out-flow and cake thickness kinetics show the familiar t”” time dependence. In addition, the hydraulic resistance of the cake was found to be pressure independent, ...

Twelve people became ill with vomiting and diarrhoea approximately four hours after eating cake with a cream filling at a birthday party and on the day following. The cake had been prepared by a food handler who had long experience in preparing foods for such functions. Staphylococcus aureus that produced enterotoxin A was isolated from the nose, the fingernails, and a healed infection on the n...

We study the problem of fair division of a heterogeneous resource among strategic players. Given a divisible heterogeneous cake, we wish to divide the cake among n players in a way that meets the following criteria: (I) every player (weakly) prefers his allocated cake to any other player’s share (such notion is known as envy-freeness), (II) the mechanism is strategy-proof (truthful), and (III) ...

The aim of the work was to define the influence of dietary supplementation with GM (genetically modified) GT#4 flaxseed cake enriched in polyphenols on inflammation development in mice liver. Mice were given ad libitum isoprotein diets: (1) standard diet; (2) high-fat diet rich in lard, high-fat diet enriched with 30% of (3) isogenic flax Linola seed cake; and (4) GM GT#4 flaxseed cake; for 96 ...

A lab-scale membrane bioreactor (MBR) was continuously operated to investigate the membrane fouling. A new membrane fouling mechanism: osmotic pressure mechanism in cake layer filtration process was identified. Osmotic pressure was proposed to stem from the retention of counter-ions in the matrix of biopolymers in cake layer. Through Fourier transform infrared (FT-IR) spectroscopy and X-ray pho...

SIMULATION OF DUST CAKE BUILD-UP ON THE FILTER MEDIUM This section describes a physical model for cake and pressure build-up on candle filters. The model was aimed at investigating filtration operation and reverse pulse cleaning of the filter. It is useful to calculate the filter cake thickness and pressure drop along the filter candle. Figure 1 shows the schematic diagram of filter cake build-...

Flaxseed cake containing antioxidants is a valuable dietary component. Its nutritional effect may be diminished by the presence of anti-nutrients. The work was aimed at determining the effect of different contents of flaxseed cake in diets and their administration period on the development of rats and selected parameters of their health status. Diets with 15% and 30% addition of genetically mod...

The objective of this study was to determine the technological and sensory characteristics sweet biscuits with addition tocosh flour tarwi flour. For which a rotational compound central design (DCCR) 22 used, giving total 11 formulations (4 factorial, 4 axial 3 points) where independent variables were X1 = Tocosh X2 Tarwi additions from 2% 8% 6% replacing percentage wheat in base formulation. r...

Filter cake trials with sugarcane in pot and field experiments have shown large yield responses to treatment with filter cake. The first invaders of filter cake were found to be yeasts and bacteria (non-spore formers) which use the free sugars still available in the filter cake. The second invaders were several fungi which were able to attack the available fibrous matter in the filter cake. In ...

AIM To assess the effect of mustard cake (Brassica juncea L.) levels in concentrate mixtures and in composite feed mixtures (CFMs) on in-vitro fermentation characteristics and methane production. MATERIALS AND METHODS Five concentrate mixtures were prepared with containing 30% oil cake, where linseed cake was replaced by mustard cake at the rate of 0%, 7.5%, 15.0%, 22.5%, and 30% in concentra...
