    Amplitudes With Different Helicity Configurations Of Noncommutative QED

    Get PDF
    The amplitudes of purely photonic and photon{2-fermion processes of non- commutative QED (NCQED) are derived for different helicity configurations of photons. The basic ingredient is the NCQED counterpart of Yang-Mills recursion relations by means of Berends and Giele. The explicit solutions of recursion relations for NCQED photonic processes with special helicity configurations are presented.Comment: 23 pages, 2 figure

    We present the first record for Anelosimus jucundus O. Pickard-Cambridge, 1896 for the state of Ceará, Brazil. We collected 22 individuals in three different ecosystems: (1) Mangrove swamps, (2) Caatinga-type desert vegetation, and (3) Montane semi-deciduous tropical forest. We corrected the misinformation of Levi’s 1963 Ceará record, was actually from the state of Pernambuco. Anelosimus jucundus presents a wide altitudinal distribution, which indicates that this species can tolerate a variety climatic conditions and can colonize a variety of sites with different vegetation155933936CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQCOORDENAÇÃO DE APERFEIÇOAMENTO DE PESSOAL DE NÍVEL SUPERIOR - CAPESFUNDAÇÃO DE AMPARO À PESQUISA DO ESTADO DE SÃO PAULO - FAPESPnão temnão temnão temThis study was financed in part by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - Brasil (CAPES), Finance Code 001 (G.A.

    Survey of Farmers Market Managers in California: Food Safety Perspectives

    Get PDF
    We conducted a survey to characterize certified California farmers markets (FMs) regarding location, seasonality, size, product, product labeling, advertising methods, postharvest practices, regulations governing vendors, training offered, and training interests. Data obtained from the survey highlight the need for improvement regarding food safety and can serve as a basis for development of collaborative education by Extension educators, regulatory agencies, and FMs. Extension professionals can play a proactive role in such training opportunities, focusing outreach efforts for training according to applicable findings and including online training venues to maximize reach to stakeholders
