The kinetics of mutator sweeps was followed in two independent populations of Escherichia coli grown for up to 350 generations in glucose-limited continuous culture. A rapid elevation of mutation rates was observed in both populations within 120-150 generations, as was apparent from major increases in the proportion of the populations with unselected mutations in fhuA. The increase in mutation ...
We characterize ring spectra morphisms from the algebraic cobordism spectrum MGL ([12]) to an oriented spectrum E (in the sense of Morel [4]) via formal group laws on the ”topological” subring E∗ = ⊕iE 2i,i of E∗∗. This result is then used to construct for any prime p a motivic Quillen idempotent on MGL(p). This defines the BP -spectrum associated to the prime p as in Quillen’s [6] for the comp...
A cyclotron for proton therapy has to fulfil many requirements set by the specific operational and safety needs of a medical facility and the medical environment. These are for instance high extraction efficiency, high availability and reliability, simple and robust operation. ACCEL Instruments GmbH has refined the design concept of a medical cyclotron for the PSI PROSCAN project with the objec...
In this study, rainbow trout (Oncorhynchus mykiss) eggs were treated with effective doses of Daenensis thyme, Thymus daenensis (20, 10 and 5 mgL-1) and Mentha, Mentha longifolia (10, 5 and 2.5 mgL-1), during incubation period (20 days) until hatching for 30 minutes per every other day as constant flow bath treatment method. The mortality level in normal control (without any treatment) was sign...
Doubled haploid production is one of the best breeding methods to produce homozygous (pure) lines. Microspore culture technique is the most efficient method for production of doubled haploid plants. This research was carried out to study the effect of genotypes, stress pre-treatments and culture media on the callus induction and plant regeneration from microspores of anthers in barley (Hordeum ...
In micropropagation of Anthurium the most important and sensitive stage, is callus induction from explant. This experiment was conducted in a completely randomized design with factorial arrangement in 4 replications in Sari Agriculture Sciences and Natural Resources University (SANRU) in 2010. The cultivar used in this study is Fire and leaf segments with and without main nervure, were used as ...
the present research was carried out to evaluate the response of seven selected persian leek accessions to in vitro gynogenesis. the experimental design was a factorial one based upon a completely randomized design of three culture media treatments b2d0 (2 mgl-1 ba), b2d2 (2 mgl-1 ba and 2 mgl-1 2, 4-d), and b2d4 (2 mgl-1 ba and 4 mgl-1 2, 4-d) along with seven persian leek accessions (gorgan, ...
Navel oranges and Clementine mandarin are classified as early cultivars and when fruits are left on the trees, fruit firmness and juice content will decrease. Plant growth regulators have been used to improve fruit quality. Gibberellic acid (GA3) and 2,4-D isopropyl ester sprays were used to increase juice content ,peel firmness and delay senescence in Navel oranges and Clementine mandarin. F...

Dog rose (Rosa canina L.) is one of the most important ornamental and medicinal plants which are used as a rootstock for ornamental roses such as Rosa hybrid and Rosa floribunda. In vitro propagation of rose has a very important role in rapid multiplication of species with desirable traits and in production of healthy and d...
