Calculation of the natural frequencies and mode shapes of a Euler–Bernoulli beam which has any combination of linear boundary conditions
(2019-09-01)
There are well-known expressions for natural frequencies and mode shapes of a Euler-Bernoulli beam which has classical boundary conditions, such as free, fixed, and pinned. There are also expressions for particular boundary ...
Acaricidal activity of thymol against larvae of Rhipicephalus microplus (Acari: Ixodidae) under semi-natural conditions
(Springer, 2015-09-01)
This is the first study to investigate the activity of thymol on Rhipicephalus microplus larvae under semi-natural conditions. For this purpose, tests were conducted in pots with Brachiaria decumbens seedlings containing ...
Designing naturally-conditioned dwellings for warm and cold-temperate regions of Chile
(Taylor & Francis, 2020)
The central problem addressed by this paper is the fuel poverty experienced in Chile as a result of poor thermal performance of dwellings, a problem commonly encountered throughout the country, even in new housing. The ...
May a natural lake behave as an efficient Fenton reactor under dark conditions?
(Springer, 2019-09)
Phenol degradation experiments were performed to study the potential behavior of the acidic Lake Caviahue (LC) as a dark Fenton reactor under natural conditions and upon H2O2 addition at doses typically used for technological ...
Suitable conditions for natural regeneration in variable retention harvesting of southern Patagonian Nothofagus pumilio forests
(SpringerOpen, 2019-06)
Background: Variable retention (aggregated and dispersed retention) harvesting proposed for Nothofagus pumilio was designed for timber purposes and biodiversity conservation. Harvesting by opening canopy generates different ...
