Gibel carp (Carassius auratus gibelio) juveniles with an average weight of 8.73± 2.1 g were fed a basal diet (control) and three experimental diets (T200, T400 and T800), containing 200, 400 and 800 mgkg-1, respectively of thyme essential oil (Thymus vulgaris) for six weeks. After six weeks feeding trial, both control and thyme essential oil-added feed groups were exposed to sub-acute toxicity ...

A pecuária é uma das principais atividades da economia brasileira e as pastagens assumem papel neste cenário. Entretanto, fatores externos como plantas daninhas tendem a diminuir produtividade, lucratividade rentabilidade propriedades rurais. Objetivou-se comparar eficiência de controle três diferentes dosagens herbicida em área infestada predominantemente pelas espécies Mimosa debilis, Malva s...

Efficacy of seven fungicides and seven plant extracts were evaluated against two pathogenic species of fungi isolated from Senna alata L. in vitro. The isolated fungi were Colletotrichum gloeosporioides (Penz.) Sacc. and Pestalotiopsis guepinii (Desm.) Stay. Seven fungicides Acrobate MZ, Bavistin 50 WP, Indofil M-45, MC Sulphur 80 WP, Ridomil MZ Gold, Sulcox 50 WP and Tall 25 EC at 100, 200, 30...

mycophenolic acid is a secondary extracellular metabolite of penicillium strains with numerous pharmaceutical properties such as antibiotic and immunosuppressive uses. the aim of this work is the survey of the effect of phenylglyoxal and n-ethylmaleimide concentration in culture medium on mycophenolic acid production by penicillium brevi-compactum atcc16024 was investigated. batch submerged fer...

Solanum nigrum was found to proliferate in sediments with high levels of metal pollution. The effect of Zn on plant growth and tissue metal accumulation was assessed. The response of the plant to the inoculation with four different isolates of arbuscular mycorrhizal fungi (AMF) (Glomus sp. BEG140, Glomus claroideum, Glomus mosseae and Glomus intraradices) was studied. While the isolates of AMF ...

Inclusive standard model Higgs boson pair production at hadron colliders has the capability to determine the Higgs boson self-coupling l . We present a detailed analysis of the gg→HH→(W1W2)(W1W2) →( j j,n)( j j,8n) and gg→HH→(W1W2)(W1W2)→( j j,n)(,8n,9n) (, ,,8,,95e ,m) signal channels, and the relevant background processes, for the CERN Large Hadron Collider, and a future Very Large Hadron Col...

The Andean region of Ecuador is being impacted by climate change, and improved best management practices for agriculture are needed to increase yields food security. We conducted a study comparing different nitrogen (N) rates determine the optimum N application rate potato (Solanum tuberosum L.) systems in this region. examined five N: 0, 100, 200, 300, 400 kg ha− 1. results suggest that an 300...
