Technology transfer and the Australian
construction industry: Exploring the relationship
between public-sector research providers and
research users
Investigates the nature of construction-related R&D programs undertaken
by public-sector organisations in Australia, and the linkages between
those organisations and the construction industry. It is found that robust
linkages do exist between the research providers and the industry. These
linkages improve the relevance of R&D programs to industry needs.
Nevertheless, research providers are found to be generally unsatisfied
about the level of industry funding of R&D. The paper highlights the
value of linkages between research providers and research users in the
construction industry.

Synthesis and characterization of rare earth oxide
based pigments

A Suryanarayana
Pleurotus sajor-caju, an important edible mushroom, is cultivated on
various combinations of neem fruit components for bioaccumulation of
active principles of neem fruit that enrich its medicinal value. Husk and
hull : kernel (1:1) results in the best cultivation with biological efficiency
up to 45.75 per cent, which is comparable to its cultivation on banana
pseudostem (47.32 per cent), a potent lignocellulosic substrate. To find
out the intensity of accumulation of medicinally important limonoids in
the fruiting bodies through HPLC, Azadirachtin, one of the limonoids, is
taken as a reference compound and it is found to be accumulated in the
fruiting bodies of P. sajor-caju (4.19 ppm). The presence of limonoids in
these mushrooms makes them a health food.
An attempt is made to prepare eco-friendly pigments, stable at high
temperature, based on earth metal oxides as replacement to the presently
available inorganic products based on lead, chromium, cadmium, and
mercury which are harmful to environment. As a first step, brilliant red
pigments, ranging from chocolate (ISC 451) to crimson red (ISC 540) are
prepared by calcinations of cerium oxalate mixed with praseodymium
oxide in varying proportions where the later acts as the chromophore.
Sodium chloride in the precursor works as a modifier to improve the
colour quality. Proper mixing of the ingredients and calcination at
1100°C (lower than the reported values of over 1300°C) are required for
the formation of pigments with the desired characteristics.

Effect of varying degree of debittered and
non-debittered kinnow serum clarified by different
methods on quality of concentrate
B B Lal Kaushal & N K Thakur
Effect of varying degree of debittered and non-debittered kinnow serum
clarified by different methods on quality of concentrate reveals that
concentration up to 72°B is obtained successfully. The reconstituted juice
from concentrate, prepared from enzymatically clarified serum, is better
in quality than the reconstituted juice prepared from serum clarified by
centrifugation. Concentrate prepared from debittered serum is found to
be superior in quality than that prepared from non-debittered serum
which obviously results in better quality juice.

Pot culture experiments are conducted during the summer season to
evaluate the effect of flyash addition in soil on germination and stand
establishment of maize (Zea mays L.) and rice (Oryza sativa L.). Flyash
levels tested are 0, 5, 10, 15, and 20 per cent, respectively, for both the
crops. The changes in soil physical and physico-chemical characteristics
due to flyash addition are analyzed. Germination time, defined as the
time taken for 75 per cent germination and delay index (DI), normalized
parameters are introduced to evaluate the flyash incorporation effects on
germination of maize and rice.
