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...

Medium from a stationary phase culture of axenically grown D. discoideum cells contains an inhibitor of cohesion of log phase cells. The inhibitor is a heat-stable, low molecular weight substance. Its biological effects include inhibition of cohesion of aggregation-competent cells, of cells of other slime mould species, the blocking of development on Millipore filters and a reduction in adhesiv...

A 25 years old lady with vaginal atresia, secondary to a mismanaged spontaneous vaginal delivery, underwent vaginoplasty using human amnion. The amnion was kept in its place using a 60cc syringe as a mould. For the next three months, dilatation by soft mould was followed by regular intercourse. Alongwith the restoration of normal coital function, she also conceived and was delivered by planned ...

Abstract At present buildings contribute a third of total greenhouse gas emissions. There is need for sustainable solutions and natural materials, which offer low-embodied energy their low impact has promising potential as construction alternatives. Hempcrete lightweight insulation material, provides natural, airtight, vapor-permeable insulation. Straw panels are also materials they consist ext...

The plasmodium of the slime mould Physarum polycephalum has recently received significant attention for its value as a highly malleable amorphous computing substrate. In laboratory-based experiments, microand nanoscale artificial circuit components were introduced into the P. polycephalum plasmdodium to investigate the electrical properties and computational abilities of hybridised slime mould....

The present study is concerned with the investigation of mechanical properties of A713 alloy castings produced by investment casting process using expandable polystyrene as the pattern material and the plaster of paris as the mould material. Experiments were conducted as per Taguchi’s L9 orthogonal array. Castings were made under the constraint of different process parameters like mould firing ...
