The ability to modify RNA secondary structure is crucial for numerous cellular processes. We have characterized two RNA helicase genes, crhB and crhC, which are differentially expressed in the cyanobacterium Anabaena sp. strain PCC 7120. crhC transcription is limited specifically to cold shock...

A comparison of reproductive and growth traits of horned and polled cattle in three synthetic beef lines
Download1999
Pang, H., Price, M. A., Goonewardene, L. A., Berg, R. T.
One hundred and thirty-seven cow-calf pairs on pasture in southeastern Alberta, were randomly allocated to one of two treatments no supplement (NOS) or a high by-pass protein (70% of CP) creep supplement (HPS) at an intake of 1.5 kg head−1 d−1. Calf weaning weights and pre-weaning ADG were higher...

Phenotypically dehorned (genetically horned) and polled bulls were similar for birth, weaning weight, pre- and post-weaning ADG, carcass weight, grade fat, marbling, rib-eye area, cutability and carcass grade. Polled bulls had higher (P < 0.02) fat over the rib-eye compared with dehorned. The...

A definition lexical classes is proposed based on the mapping between the prototypical semantic and the unmarked syntactic properties of nouns and verbs which at once captures cross-linguistic generalizations made by previous authors and at the same time explains the typological variation shown...

We observed a case of adoption of a single four-month-old polar bear cub (Ursus maritimus) into an existing litter of two cubs on Hopen Island, Svalbard. We believe the high density of maternity dens in the study area may increase the likelihood of natural adoption. Speculation about theoretical...

An approach to evaluation of field CPTU dissipation data in overconsolidated fine-grained soils
Download1999
Campanella, R., Robertson, P. K., Woeller, D., Sully, J.
Abstract: Dissipation of excess pore pressures during piezocone testing in firm to stiff overconsolidated fine-grained soils provides data curves that cannot be interpreted using published theoretical solutions. Available solutions are based on either cavity-expansion or strain-path methods,...

Tikhonchuk, V. T., Voronkov, I., Samson, J. C., Rankin, Robert
A model is presented that describes the excitation of density perturbations and parallel electric fields by standing shear Alfven waves on dipole fields in Earth's magnetosphere. The model includes the effects of electron inertia and gyro-kinetic dispersion, accounting for field-aligned...

Composition and correlation studies of fatty acids in seed oil of yellow sarson (Brassica campestris L.) cultivars and backcross derived zero erucic acid yellow sarson populations
Download1999-01-01
Rahman, M. H., Stølen, O., Rahman, L., Rahman, M. M.
The Yellow Sarson (Brassica campestris) cultivars of Bangladesh origin contain a high level (54%) of erucic fatty acid (C22:1). In the seeds of backcross derived zero-erucic acid Yellow Sarson populations, absence of erucic acid caused a simultaneous reduction in the content of arachidic (C20:0),...

Density-dependent variation in lifetime breeding success and natural and sexual selection in Soay rams
Download1999
Smith, J.A., Bancroft, D.R., Clutton-Brock, T.H., MacColl, A.D., Pilkington, J., Coltman, D.W., Pemberton, J.M.
Variation in male lifetime breeding success (LBS) is central to understanding selection, yet it has rarely been measured in natural populations of large mammals. Here, we first describe variation in the opportunity for selection in cohorts of Soay rams (Ovis aries) on the archipelago of St....
