Strong γ-ray emission from cocoons of young radio galaxies is newly predicted. Considering the process of adiabatic injection of the shock dissipation energy and mass of the relativistic jet in active nuclei (AGNs) into the cocoon, while assuming thermalizing electron plasma interactions, we find that the thermal electron temperature of the cocoon is typically predicted in ∼MeV, which is determ...

Silk cocoons, produced by Bombyx mori L. (Bombicidae) are used to treat heart palpitation, cough, asthma and catarrh. Phytochemical investigation of the cocoons led to the isolation of alkyl substituted dioxymethylene benzene derivatives and two citronellyl glucosides for the first time characterized as n-pentanyl-3,4-(dioxymethylene) benzene (1), n-pentanyl-2,3-dioxymethylene-4-hydroxybenzene ...

Eisenia fetida were exposed continuously to (60)Co gamma radiation during two generations (F(0) and F(1)). Adult F(0) reproduction capacity (i.e., number of cocoons produced, hatchability and number of F(1) hatchlings) in controls and at five dose rates (0.18, 1.7, 4, 11 and 43 mGy/h) was measured over a 13-week exposure period. Survival, growth and sexual maturation of F(1) hatchlings were obs...

Bombyx mori cocoon has a multi-layer structure that provides optimal protection for silkworm pupa. Research on the mechanical properties of the multi-layer structure revealed structure-property relationships of the cocoon. Here, we investigated the protein components of the B. mori cocoon in terms of its multi-layer structure. Liquid chromatography-tandem mass spectrometry identified 286 protei...

Antheraea mylitta.D. is a wild sericigenous and polyphagous insect which feeds on Terminalia arjuna and Terminalia tomentosa. It has an exclusive race in this region known as Andhra local. Due to certain weaknesses in acclimatization at different stages, this ecorace is showing signs of extinction. Present communication is based on indoor rearing of Andhra local and studies on morphological and...

A 10-wk study of the avocado seed-feeding moth Stenoma catenifer Walsingham (Lepidoptera: Elachistidae), was conducted in a commercial 'Hass' avocado (Persea americana Miller [Lauraceae]) orchard in Guatemala. Up to 45% of fruit in the orchard were damaged by larval S. catenifer. Larval-to-adult survivorship for 1,881 S. catenifer larvae in Hass fruit was 37%, and adult sex ratio was 51% female...

The aim of this study was to investigate the effects of Elado® (10 g clothianidin & 2 g beta-cyfluthrin/kg seed)-dressed oilseed rape on the development and reproduction of mason bees (Osmia bicornis) as part of a large-scale monitoring field study in Northern Germany, where oilseed rape is usually cultivated at 25-33 % of the arable land. Both reference and test sites comprised 65 km2 in which...
