However, the evolutionary relationship of L338 with other ERVs is still unknown. Here whole genome analysis of the L338 ERV strain was independently performed. Its genotype constellations were determined as G13-P[18]-I6-R9-C9-M6-A6-N9-T12-E14-H11, confirming previous genotype assignments. The L338 strain only shared the P[18] and I6 genotypes with other ERVs. The nucleotide sequences of the other 9 RNA segments were different from those of cogent genes of all other group A rotavirus (RVA) strains including ERVs and formed unique phylogenetic lineages. The L338 evolutionary footprints were tentatively identified in both VP7 and VP4 amino acid sequences: two regions were found in VP7 and twelve in VP4. The conserved regions shared between L338 and other group A rotavirus strains (RVAs) indicated that L338 was more closely related genomically to animal and human RVAs other than ERVs, suggesting that L338 may not be an endogenous equine RV but have emerged as an interspecies reassortant with other RVA strains. Furthermore, genotype-specific motifs of all 27 G and 37 P types were identified in regions 7-1a (aa 91-100) of VP7 and regions 8-1 (aa146-151) and 8-3 (aa113-118 and 125-135) of VP4 (VP8*).

The volumetric and mass injection rates, as well as the macroscopic spray parameters, such as the spray penetration distance, spray cone angle, projected spray area, spray front velocity, maximum spray width, and light intensity level of different test fuels, are analyzed in detail. It is found that fuel property places an important influence on injection characteristics. Similarly, the fuel physical properties also lead to some distinctions in the macroscopic spray parameters.

Microspore culture reveals complex meiotic behaviour in a trigenomic Brassica hybrid

[More] BACKGROUND: Development of synthetic allohexaploid Brassica (2n = AABBCC) would be beneficial for agriculture, as allelic contributions from three genomes could increase hybrid vigour and broaden adaptation. Microspore culture of a near-allohexaploid hybrid derived from the cross (B. napus × B. carinata) × B. juncea was undertaken in order to assess the frequency and distribution of homologous and homoeologous crossovers in this trigenomic hybrid. SNP and SSR molecular markers were used to detect inheritance of A, B and C genome alleles in microspore-derived (MD) progeny. SNP allele copy number was also assessed. The MD progeny were also compared to progeny derived by self-pollination and open-pollination for fertility (estimated by self-pollinated seed set and pollen viability) and DNA ploidy (measured by flow cytometry).

RESULTS: In the trigenomic hybrid, homologous chromosome pairs A(j)-A(n), B(j)-B(c) and C(n)-C(c) had similar meiotic crossover frequencies and segregation to that previously observed in established Brassica species, as demonstrated by marker haplotype analysis of the MD population. Homoeologous pairing between chromosomes A1-C1, A2-C2 and A7-C6 was detected at frequencies of 12-18 %, with other homoeologous chromosome regions associating from 8 % (A3-C3) to 0-1 % (A8-C8, A8-C9) of the time. Copy number analysis revealed eight instances of additional chromosomes and 20 instances of chromosomes present in one copy in somatically doubled MD progeny. Presence of chromosome A6 was positively correlated with self-pollinated seed set and pollen viability in the MD population. Many MD progeny were unable to produce self-pollinated seed (76 %) or viable pollen (53 %), although one MD plant produced 198 self-pollinated seeds. Average fertility was significantly lower in progeny obtained by microspore culture than progeny obtained by self-pollination or open-pollination, after excluding MD progeny which had not undergone chromosome doubling.

CONCLUSIONS: Based on SNP data analysis of the microspore-derived progeny, crossover frequency per chromosome in the allohexaploid hybrid was found to be similar to that in established Brassica species, suggesting that the higher chromosome number did not significantly disrupt cellular regulation of meiosis. SNP allele copy number analysis revealed the occurrence not only of homoeologous duplication/deletion events but also other cryptic duplications and deletions that may have been the result of mitotic instability. Microspore culture simplified the assessment of chromosome behaviour in the allohexaploid hybrid but yielded progeny with lower fertility and a greater range of ploidy levels compared to progeny obtained by self- or open-pollination.

[More] An array of new MCM-41 with substantially larger average pore diameters was synthesized through adding 1,3,5-trimethylbenzene (TMB) as the swelling agent to explore the effect of pore size on final adsorbent properties. The pore expanded MCM-41 was also grafted with (3-Aminopropyl)triethoxysilane (APTES) to determine the optimal pore size for CO2 adsorption. The pore-expanded mesoporous MCM-41s showed relatively less structural regularity but significant increments of pore diameter (4.64 to 7.50 nm); the fraction of mesopore volume also illustrated an increase. The adsorption heat values were correlated with the order of the adsorption capacities for pore expanded MCM-41s. After amine functionalization, the adsorption capacities and heat values showed a significant increase. APTES-grafted pore-expanded MCM-41s depicted a high potential for CO2 capture regardless of the major drawback of the high energy required for regeneration.

Effect of stereo-configurational difference of carbohydrate model compound on the reaction with active oxygen species under oxygen delignification conditions

[Less] We examined how the stereo-configurational difference affects the reaction of a carbohydrate model compound . . . [More] We examined how the stereo-configurational difference affects the reaction of a carbohydrate model compound with active oxygen species (AOS) generated in situ by reactions between O-2 and a phenolic compound under conditions similar to those of oxygen delignification or with oxyl anion radical, the conjugate base of hydroxyl radical, generated by the decomposition of H2O2 under alkaline conditions. As the phenolic compound, 2,4,6-trimethylphenol or 4-hydroxy-3-methoxybenzyl alcohol (vanillyl alcohol) was used. The carbohydrate model compounds employed were methyl beta-d-glucopyranoside (MGP beta) and its 4 epimers, methyl alpha-d-glucopyranoside (MGP alpha), methyl beta-d-mannopyranoside (MMP), methyl beta-d-allopyranoside (MAP), and methyl beta-d-galactopyranoside (MGaP). Their stabilities were in the order of MGP alpha > MGP beta > MMP > MGaP > MAP, indicating that the reactivity of the carbohydrate model compound is significantly dependent on where the stereo-configurational difference is. Only the co-existence of MMP enhanced the degradation of MGP beta, when a pair of MGP beta and another carbohydrate model compound was reacted with the AOS. This result suggests that the profile of AOS in the system is dependent not only on the type of phenolic compound, the generator of AOS, but also on that of the carbohydrate model compound.

[More] Rate constants for the dimerization of FeCp*C6H6, RuCp*mes, RhCp2, RhCp*Cp, and IrCp*Cp (Cp* = pentamethylcydopentadienyl; mes = 1,3,5-trimethylbenzene; Cp = cydopentadienyl) have been investigated by cyclic voltammetry. Rates increased in the order FeCp*C6H6 << RhCp*Cp similar to RhCp2 < RuCp*mes and IrCp*Cp. The difference in rates between the Rh compounds and the Ru and Ir species is consistent with the thermodynamic driving forces for dimerization estimated from DFT calculations. However, the sluggish dimerization of FeCp*C6H6 cannot be rationalized with purely thermodynamic considerations and may be attributable to the very different spin-density distribution in this species. On the basis of the activation parameters for dimerization, determined by variable temperature cyclic voltammetry, and those previously dissociation of the corresponding dimer, the free energy of dimerization for the RhCp*Cp monomer was estimated to be -43 kJ mol(-1), and the effective redox potential for the RhCp*Cp+ / 0.5(RhCp*Cp)(2) couple was estimated as -1.84 V vs FeCp2+/FeCp2. determined for
