Infinities within graviton scattering amplitudes

We present unitarity as a method for determining the infinities present in graviton scattering amplitudes. The infinities are a combination of IR and UV. By understanding the soft singularities we may extract the UV infinities and relate these to counter-terms in the effective action. As an demonstration of this method we rederive the UV infinities present at one-loop when gravity is coupled to matter.Comment: revised versio

Biological and molecular characterization of an isolate of Tobacco streak virus obtained from soybeans in Brazil.

A virus was isolated from soybean (Glycine max) plants with symptoms of dwarfing and bud blight in Wenceslau Braz County, Paraná, Brazil. The host range and properties resembled those of Tobacco streak virus (TSV). The purified virus showed three peaks in a frozen sucrose gradient. Antiserum was produced and the virus was serologically related to TSV. Electron microscopy detected 28 nm spherical particles. Coat protein (CP) had a Mr of 29.880 Da. A fragment of 1028 nt was amplified, cloned and sequenced. One open reading frame with 717 nt was identified and associated to the CP. The CP gene shared 83% identity with the sequence of TSV CP from white clover (Trifolium repens) (GenBank CAA25133). This is the first report of the biological and molecular characterization of TSV isolated from soybeans. It is proposed that this isolate be considered a strain of TSV named TSV-BR

Rendimento de biomassa da palma Miúda irrigada sob doses de adubação orgânica e intensidades de corte.

Resumo: No semiárido nordestino existe um severo déficit na oferta de forragem e a palma forrageira apresenta-se como uma alternativa para melhorar o desempenho dos rebanhos. No entanto, em vários municípios do Rio Grande do Norte ocorrem murchas severas da palma. Assim, a utilização da irrigação com quantidade mínima de água tem sido uma opção para sua produção nessas regiões. A pesquisa objetivou avaliar o efeito da adubação orgânica e de diferentes intensidades de corte sobre a produção de matéria verde (PMV) e seca (PMS) da palma forrageira cv. Miúda (Nopalea cochenillifera) sob condições de irrigação com 12 meses de rebrota. Foi utilizado o delineamento inteiramente casualizado em parcelas subdivididas, onde as doses da adubação orgânica (20, 40 e 60 Mg ha-1 ano-1) constituíram às parcelas e as intensidades de corte (deixando somente o cladódio mãe, todos os primários e todos os secundários) as subparcelas, com seis repetições. O plantio foi feito no espaçamento 2,0 x 0,10 m (50.000 plantas ha-1). A água utilizada na irrigação foi classificada como C4S1T3. A lâmina aplicada foi de cinco litros (2,5 mm) por metro a cada sete dias ou 10 mm por mês. O sistema de irrigação foi o de gotejamento em fileiras simples. As intensidades de corte e adubação orgânica influenciaram a PMV e a PMS. A maior PMS (30,47 Mg ha-1ano-1) foi obtida quando todos os cladódios secundários foram preservados e com aplicação de 37,5 Mg ha-1ano-1de esterco bovino. [Biomass yield of irrigated Miúda spineless forage cactus under organic fertilization doses and different cutting intensities]. Abstract: In the Brazilian Northeast semi-arid region there is a severe deficit in the supply of fodder and forage and cactus pear is an important alternative to improve the performance of the herds. However, in several municipalities of Rio Grande do Norte State occur severe withered of these cacti. Thus, the use of irrigation with a minimum amount of water has been an option for production in these regions. The research aimed to evaluate the effect of organic fertilizer (bovine manure) and different cutting intensities on the production of fresh (PFM) and dry matter (PDM)) of spineless cactus pear cv. Miúda (Nopalea cochenillifera) under irrigation with 12 months of regrowth. A completely randomized design with a split plot was applied, where organic fertilizers doses (20, 40 and 60 Mg ha-1 yr-1) were the main plots and cutting intensities (leaving only the mother cladode, all primary and all secondary cladodes), the subplots, with six replicates. The planting was done in 2.0 x 0.10 m spacing (50,000 plants ha-1). The water used for irrigation was classified as C4S1T3. The lamina applied was 2.5 mm every seven days or 10 mm month-1. The irrigation system was dripping in single rows. The cutting intensities and organic fertilization influenced the PFM and PDM. The highest PDM (30.47 Mg ha-1 yr-1) was obtained when all secondary cladodes were preserved with an application of 37.5 Mg ha-1 yr-1 of bovine manure

Constraints on Four Fermion Contact Interactions from Precise Electroweak Measurements

We establish constraints on a general four-fermion contact interaction from precise measurements of electroweak parameters. We compute the one-loop contribution for the leptonic $Z$ width, anomalous magnetic, weak-magnetic, electric and weak dipole moments of leptons in order to extract bounds on the energy scale of these effective interactions.Comment: 16 pages, RevTeX, two figure
