Capture–recapture experiments are conducted to estimate population parameters such as size, survival rates, and capture rates. Typically, individuals captured given unique tags, then recaptured over several time periods with the assumption that these tags not lost. However, for some populations, tag loss cannot be assumed negligible. The Jolly-Seber model is used when no-tag-loss invalid. Furth...

We demonstrate that by combining two robust theoretical quantum chemistry calculation techniques, stepwise ionization of C60 fullerene UV and extreme photons can in principle occur up to a limit as high C6026+ before coulomb explosion the cage. Furthermore, these highly ionized forms exhibit comparable structural bonding stability for neutral fullerene. Certain astrophysical sources like centra...

Impact of Atlantic salmon (Salmo salar) cage culture in Mjoifjordur, Eastern Iceland on the chemistry of the sediment was investigated. Sediment samples were collected using a Shipek grab in December 2003. A core sub-sample was taken from each grab for analyzing total organic matter, total organic carbon, total nitrogen and phosphorus in different depths from three stations at various distances...

OBJECTIVE To investigate the fauna and host feeding preferences of sandflies as for domestic animals in an endemic area of American cutaneous leishmaniasis. METHODS The sandflies collections were carried out from 8:00 pm to 12:00 am in an area 40 meters away from one of the residences in a farm in Southern Brazil, between January and April, 2004. Collection was performed using four Falcão lig...

Fullerene C60 and its derivatives are widely used in molecular electronics, photovoltaics, battery materials, because of their exceptional suitability as electron acceptors. In this context, single-electron transfer on generates the C60• – radical anion. However, short lifetime free hampers investigation application. work, we dramatically stabilize usually short-lived species within a self-asse...

The attraction response of Stomoxys calcitrans (L.) to its own feces was evaluated in a triple cage olfactometer. Both time- and concentration-response relationships were obtained for female S. calcitrans exposed to cellulose sponges impregnated with fresh fly feces or filter papers treated with chloroform:methanol extracts of fresh fly feces in 6-min tests. Attraction to feces collected on cel...

A total number of 66 day old Japanese quail chicks divided into 2 treatment groups (33 in each treatment) with 3 replications in each having 11 birds (male, 5 and female, 6) were reared on floor and in cage system for a period of 5 weeks to know the effect of rearing system on growth performance and carcass characteristics. At the age of 35 days, average body weight and feed intake were 102.15 ...

Parent (re-emerged) spruce bark beetles (Ips rypographus L., Col.; Scolytidae) beginning a second host-seeking flight were collected in pheromone-baited traps. These beetles were marked with fluorescent powder of different colors and released from a point source (9-16 June 1989) within a spruce, Picea abies L., forest (Jurbarkas forest district, Lithuania). Some of the marked beetles were recap...

6-amino-1,2,4-triazolo[4,3-b][1,2,4,5]tetrazine (attz)is an explosive material, that has been synthesized from the reaction of 3,6-diaminotetrazine , with nitrous acid and then sodium azide. in the simplest terms, an explosive is defined as a substance, which on initiation by friction, impact, shock, spark, flame, heating, or any simple application of an energy pulse, undergoes a rapid chemical...
