The role of abscisic acid and water relations in drought responses of subterranean clover [PDF]
The role of water relations and abscisic acid (ABA) in the responses to drought were studied in a mediterranean forage crop, Trifolium subterraneum L. under field conditions.

The effects of carboxylic acids on the aqueous dispersion and electrophoretic deposition of ZrO2 [PDF]
The agglomeration, electrokinetic properties and electrophoretic deposition behaviour of aqueous suspensions of ZrO2 with carboxylic acid additives were studied in comparison with conventional pH adjustment. It was found that citric acid imparted negative zeta-potential values and electrosteric stabilisation to particles in suspensions at all pH levels.

Nature's Starships. I. Observed Abundances and Relative Frequencies of Amino Acids in Meteorites [PDF]
The class of meteorites called carbonaceous chondrites are examples of material from the solar system which have been relatively unchanged from the time of their initial formation. These meteorites have been classified according to the temperatures and physical conditions of their parent planetesimals.

Improvement of seed germination of Fagus orientalis Lipsky [PDF]
This thesis was seeking two main approaches for improvement of seed germination of oriental beech, a timber producing species in Hyrcanian forests in northern Iran. Germination behavior of beechnuts was enhanced either by decreasing the dormancy breakage

Dormancy in wheat grain (Triticum aestivum L.) : studies on grain-coat pigment formation and abscisic acid content during the development of wheat grain of six genotypes : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Botany at Massey University [PDF]
Dormancy in wheat grain has been associated with red pigmentation of the grain-coats. The development from anthesis to harvest-ripeness of two-white-grained and four red-grained genotypes of varying dormancy was investigated. Grain growth was measured as

Low temperature in early spring impairs wheat growth and grain yield. However, little is known about the cytological and molecular mechanisms underlying low temperature regulation of wheat spike development.

Meteoritic Abundances of Fatty Acids and Potential Reaction Pathways in Planetesimals [PDF]
The origin of fatty acids on the prebiotic Earth is important as they likely formed the encapsulating membranes of the first protocells. Carbon-rich meteorites (i.e., carbonaceous chondrites) such as Murchison and Tagish Lake are well known to contain these molecules, and their delivery to the early planet by intense early meteorite bombardments ...
