This paper reports on the recent outcomes from our research into Unconventional Computing for sound and music using slime mould of Physarum polycephalum. This slime mould is a huge single cell with thousands of nuclei, which behaves like a giant amoeba. During its foraging behaviour it produces electrical activity corresponding to different physiological states. We developed a method to render ...

THE fat content of mould mycelium, as reported by various authors, ranges from 1 to 40 %, depending upon the species and upon the conditions of growth. Even within a single strain of a species certain characteristics of the fat, as well as its amount, have been reported to vaty with the conditions of growth. From what is known about the chemical composition of mould-fat it appears that glycerid...

Slime mould P. polycephalum is a single cells visible by unaided eye. The cells shows a wide spectrum of intelligent behaviour. By interpreting the behaviour in terms of computation one can make a slime mould based computing device. The Physarum computers are capable to solve a range of tasks of computational geometry, optimisation and logic. Physarum computers designed so far lack of localised...

The influence of temperature on the growth of the mould Penicillium roqueforti growing on malt extract agar was studied by correlating the produced heat (measured by isothermal calorimetry), ergosterol content (quantified by GC-MS/MS) and biomass of the mould at 10, 15, 20, 25 and 30 degrees C. The results were analysed with a simple metabolic model from which the metabolic efficiency was calcu...

Slime mould Physarum polycephalum is a single cell visible by the unaided eye. Let the slime mould span two electrodes with a single protoplasmic tube: if the tube is heated to approximately ≈40 °C, the electrical resistance of the protoplasmic tube increases from ≈3 MΩ to ≈10,000 MΩ. The organism's resistance is not proportional nor correlated to the temperature of its environment. Slime mould...

A diploid and a haploid strain of Pichia anomala were tested for their biocontrol ability against the spoilage mould Penicillium roqueforti in glass tubes filled with grain at two water activities (aw). At aw 0.98, the two yeast strains grew and inhibited mould growth equally well and showed similar patterns of ethyl acetate production, reaching maximum values of 10-14 microg ml(-1) headspace. ...

This Study was carried out on 40 random samples of cooked chicken products represented by chicken luncheon and Shawerma (20 of each). Samples were collected from different markets at Al-Taif governorate, KSA. and subjected to some microbiological investigations; including determination of total aerobic plate, Enterobacteriacae spp, E.coli, Staph.spp., Staph.aureus bacterial count, mould and yea...

The internal quality of apple is impossible to be detected by eyes in the procedure of sorting, which could reduce the apple’s quality reaching market. This paper illustrates an instrument using X-ray and machine vision. The following steps were introduced to process the X-ray image in order to determine the mould core apple. Firstly, lifting wavelet transform was used to get a low frequency im...

The cooling channels of injection mould play a crucial role in determining the productivity of moulding process and the product quality. It’s not a simple task to design high quality cooling channels. In this paper, an intelligent cooling channels design system including automatic layout of cooling channels, interference checking and assembly of accessories is studied. Automatic layout of cooli...

Slime mould of Physarum polycephalum is a large cell exhibiting rich spatial non-linear electrical characteristics. We exploit the electrical properties of the slime mould to implement logic gates using a flexible hardware platform designed for investigating the electrical properties of a substrate (Mecobo). We apply arbitrary electrical signals to ‘configure’ the slime mould, i.e. change shape...
