This study evaluated the oil extraction from Euphorbia lagascae seeds by pre-pressing followed solvent extraction. The objective was to assess effect of starting seed moisture content (MC) and heating temperature on extractability quality pressed solvent-extracted oils. expelling conditions (5% 10% MC) that were subjected three levels (ambient, 60 °C 104 for 20 min) then screw-pressed. press ca...

INTRODUCTION In many chemical and pharmaceutical processes, solid-liquid separation, cake washing and drying steps directly impact the effectiveness of the production operation. Process engineers devote much of their time to analyzing these steps. The solid-liquid separation step can be by pressure, vacuum or centrifugation as well as in a batch or continuous mode. In this separation step, ther...

In urban areas of low-income countries, treatment of faecal sludge (FS) is insufficient or non-existent. This results in large amounts of FS being dumped into the environment. Existing treatment technologies for FS, such as settling-thickening tanks and drying beds, are land intensive which is limiting in urban areas. Enhanced settling and dewatering by conditioning was evaluated in order to re...

Using natural waste as a source of minerals and biostimulants can offer many advantages in the production plants containers. The research aimed to evaluate usefulness cakes obtained from camelina seed oil (Camelina sativa) cultivation ferns. greenhouse experiment used ornamental ferns rich health-promoting compounds: Onoclea sensibilis, Polypodium vulgare, Polystichum polyblepharum. Plants were...

A cake is a metaphor for a heterogeneous, divisible good, such as land. A perfect division of cake is efficient (also called Pareto-optimal), envyfree, and equitable. We give an example of a cake in which it is impossible to divide it among three players such that these three properties are satisfied, however many cuts are made. It turns out that two of the three properties can be satisfied by ...

Fair Division, unlike most research on fairness in the social sciences and mathematics, is devoted solely to the analysis of constructive procedures for actually dividing things up and resolving disputes, including...

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...

The aim of this study was to evaluate biogeographic variability in the fruit, kernel, kernel-oil and press-cake contents 50 accessions beauty leaf tree (C. inophyllum L.) collected from 19 locations spanning 4000 km along eastern northern coasts Australia (Northern Territory Queensland). Mature fallen fruits C. were individual trees stored a shed for over year. cracked open extract kernels, ker...
