Variation in seroprevalence of antibodies against Mycoplasma gallisepticum and Avipoxvirus in nine species of birds with differential access to feeders

Posted on 9. March, 2018.

Congregation of individuals at high densities is known to increase disease transmission and bird-feeding activities are specifically aimed at attracting many birds to a single location. Studies have shown that implementing bird feeders increases the likelihood of host infection to Mycoplasma gallisepticum, a causative agent of conjunctivitis in birds.

Mathematical models of microbial growth and metabolism: a whole-organism perspective

Posted on 7. March, 2018.

Life on Earth can be divided into several kingdoms, with the prokaryote domains of the Archaea and the Bacteria standing out by dint of their vast metabolic diversity and versatility which is belied by the paltry morphological variation encountered in these domains.

Free for 24 hours - The mechanism of the reaction of the Tollens reagent

Posted on 7. March, 2018.

The Tollens test for aldehydes has been used for over 100 years but no reason has been given for adding sodium hydroxide to the silver nitrate before the solution is cleared with ammonia. In this paper, a mechanism is proposed which explains why the addition of alkali makes the test much more sensitive.

A Free Review from Progress in Reaction Kinetics and Mechanism: Halocarbenes may deplete atmospheric ozone

Posted on 6. March, 2018.

The stratospheric ozone layer protects biological processes on Earth by absorbing the more harmful solar UV radiation. The discovery of the loss of stratospheric O3 led to investigations to find the cause. It was found that chlorofluorocarbons had long atmospheric lifetimes and could reach the stratosphere where they photocleaved to yield Cl atoms which destroyed O3 in a catalytic chain reaction.

A convenient synthesis of gimeracil

Posted on 6. March, 2018.

A practical three-step synthetic approach to gimeracil in a 68% overall yield is described, using 2,4-dimethoxypyridine as the starting material with 3,5-dichloro-2,4-dimethoxypyridine and 3,5-dichloro-2,4-dihydroxypyridine as intermediates. The advantages of this procedure include short reaction steps, simple operation and good yield.

Weather-dependent variation in the winter diet of urban roosting Long-eared Owls (Asio otus) in Pécs (Hungary)

Posted on 5. March, 2018.

Long-eared Owls usually winter in groups, mainly on evergreen trees in settlements, They hunt at night and rest in trees during the day. The indigestible parts of the prey (e.g. bones, hair, feathers and chitin) are regurgitated in the form of pellets, from which one can conclude the composition of their diet.
