We use a family of algebraic foliations given by A. Lins Neto to provide new evidences to a conjecture, related to the Harbourne-Hirschowitz's one and implying the Nagata's conjecture, which concerns the structure of the Mori cone of blow-ups of P 2 at very general points. Also, we give an explicit family of smooth projective rational surfaces X such that the set of faces of the Mori cone N E(X...

This paper discusses the author’s artwork, Neuro Memento Mori, a self-portrait comprising digital animations and live action video projection-mapped onto a 3D print. The life-sized sculpture of the head and neck, dissected to reveal the artist’s brain, was produced from MRI data gathered as the artist viewed memento mori paintings and meditated on death. The production of the artwork, made with...

The theoretical description of the dynamics of liquids by the theory of Mori and Zwanzig is in practice mostly applied to simple liquids, where the molecules have no internal structure. Recently a second-order Mori-Zwanzig model for the incoherent intermediate scattering function has been employed in order to interpret quasielastic neutron scattering QENS experiments on water and aqueous soluti...

Use of Juvenile Hormone Analogues (JHA) in sericulture practices has been shown to boost good cocoon yield; their effect has been determined to be dose-dependent. We studied the impact of low doses of JHA compounds such as methoprene and fenoxycarb on selected key enzymatic activities of the silkworm Bombyx mori. Methoprene and fenoxycarb at doses of 1.0 microg and 3.0 fg/larvae/48 hours showed...

The minichromosome maintenance protein (MCM) family is involved in the regulatory role of DNA replication in eukaryotic organisms. A cDNA encoding of an MCM of the silkworm, Bombyx mori L. (Lepidoptera: Bombycidae), was cloned by reverse transcriptase-polymerase chain reaction (RT-PCR) and sequenced. The resultant amino acid sequence and phylogenetic analysis revealed high identity to MCM, and ...

The silkworm, Bombyx mori is infected by a number of viruses: Bombyx mori nuclear polyhedrosis virus (BmNPV), cytoplasmic polyhedrosis virus (CPV), infectious flacherie virus (IFV) and densonucleosis virus (DNV). Except DNV, resistance of silkworms to the virus is controlled by polygenes. Serologically, two DNV types, DNV-1 and DNV-2 are identified. The non-susceptibility to DNV types is confer...

hook worm (necator americanus) is one of the major pathogenic parasites in the north of iran. neonatal hamsters 1-3 days old showed a high degree of susceptibility to necator americanus infection and the parasite reached to sexually mature stages in six weeks following skin exposure. this method could be used for production of egg, larvae and adult worms. in this study neonatal hamsters were in...
