In this paper, we settle Alspach’s problem in the case of Hamilton cycles and 5cycles; that is, we show that for all odd integers n ≥ 5 and all nonnegative integers h and t with hn + 5t = n(n − 1)/2, the complete graph Kn decomposes into h Hamilton cycles and t 5-cycles and for all even integers n ≥ 6 and all nonnegative integers h and t with hn+5t = n(n−2)/2, the complete graph Kn decomposes i...

The natural variation in leaf and plant longevity in Arabidopsis thaliana was analysed in a set of 45 ecotypes and 155 recombinant inbred lines derived from a Cape Verde Islands (Cvi) x Landsberg erecta (Ler) cross. Post-bolting longevity was inversely related to time to flowering and rosette leaf number in the set of 45 ecotypes, with Cvi having the longest and Ler the shortest post-bolting lo...

In the presence of water and amines etherate bicyclic Al2(OSiPh2OSiPh2O)3 (II a) can be used to generate novel alumosiloxane polycycles like [O(Ph2SiOSiPh2)O−]2Al2O[O(Ph2SiOSiPh2)O] ⋅ 2 H2N+Et2 (1), [O(Ph2SiOSiPh2)O−]2Al2[O(Ph2Si)O]2 HN+Et3 (2), [O(Ph2SiOSiPh2)O−]2Al2[O(Ph2SiOSiPh2)O]2 (3 a, 3 b), which crystallizes in two different phases, HN+(CH2CH2)3N (4). As a common structural feature thes...

OBJECTIVES There is no formal agreement or criteria utilized to establish a standard of treatment in children with antenatally diagnosed HN. METHODS We analyzed our own experience in addition to the protocols attending to this subject. Twenty eight (28) children with unilateral HN were assessed from October 1999 through October 2005 and the anteroposterior diameter of renal pelvis (APDP) was ...

We consider a sequence HN of finite-dimensional Hilbert spaces of dimensions dN → ∞. Motivating examples are eigenspaces, or spaces of quasi-modes, for a Laplace or Schrödinger operator on a compact Riemannian manifold. The set of Hermitian orthonormal bases of HN may be identified with U(dN), and a random orthonormal basis of is a choice of a random sequence UN∈U(dN) from the product of normal...

Heart interneurons (HN cells) in isolated ganglia of the medicinal leech were voltage-clamped with single microelectrodes. Hyperpolarizing voltage steps elicited a slow inward current (I,,), which underlies the characteristic depolarizing response of HN cells to injection of prolonged hyperpolarizing current pulses (Arbas and Calabrese, 1987a). The conductance underlying /,, begins to activate ...

Interactive effects of solar radiation and inorganic nitrogen phosphate on biofiltration capacity, biomass production, photosynthetic activity the accumulation bio-active compounds were studied in red alga Gracilaria cornea grown tanks with a seawater open-flow system during 35 days. Two light conditions utilized: outdoor (O), full natural radiation, indoor, inside greenhouse (G) where UV-B was...

malignant tumors of head and neck carcinomas are the sixth most common type of cancer. current systemic therapies for cancer show side effects in normal tissues and short-term efficacy due to drug resistance. consequently, there is much interest in identifying new drugs for cancer treatment. crocin (an active ingredient of saffron) has been shown to have cytotoxic effects on cancer cell lines. ...

Trichosanthin (TCS) is a type I ribosome--inactivating protein, which inhibits cell viability in human epithelial type 2 (HEp-2) and AMC-HN-8 human laryngeal epidermoid carcinoma cells. Although TCS is a potential chemotherapeutic agent, its mechanism of action remains to be elucidated. In the present study, HEp-2 and AMC-HN-8 cells were treated with different concentrations of TCS combined wit...

Suppose that K ⊂ U(n) is a compact Lie group acting on the (2n+1)dimensional Heisenberg group Hn. We say that (K,Hn) is a Gelfand pair if the convolution algebra LK(Hn) of integrable K-invariant functions on Hn is commutative. In this case, the Gelfand space ∆(K,Hn) is equipped with the GodementPlancherel measure, and the spherical transform ∧ : LK(Hn)→ L(∆(K,Hn)) is an isometry. The main resul...
