Active galactic nuclei: sources for ultra high energy cosmic rays
(WORLD SCIENTIFIC PUBL CO PTE LTD, 2009)
Ultra high energy cosmic ray events presently show a spectrum, which we interpret here as galactic cosmic rays due to a starburst, in the radio galaxy Cen A which is pushed up in energy by the shock of a relativistic jet. ...
AKT and AMPK activation after high-fat and high-glucose in vitro treatment on prostate epithelial cells.
(Amer Soc Cell Biology, 2012-01-01)
Antidiabetic, cytotoxic and antioxidant activities of oil extracted from Acrocomia aculeata pulp
(2018-03-01)
This study evaluated the hypoglycemic effect of the oil extracted from the Acrocomia aculeata pulp (OPAC) in normoglycemic rats and streptozotocin (STZ), fructose-induced diabetic rat models and its in vitro antioxidant ...
Delayed onset of electromyographic activity of the vastus medialis relative to the vastus lateralis may be related to physical activity levels in females with patellofemoral pain
(2016-02-01)
The aims of this study were to examine group differences in muscle activation onset of the vastus medialis (VM) in relation to the vastus lateralis (VL) and pain level during stair ascent in females with patellofemoral ...
Contrasting activity patterns at high and low tide in two Brazilian fiddler crabs (Decapoda: Brachyura: Ocypodidae)
(Oxford Univ Press, 2018-07-01)
Fiddler crabs are known as ecosystem engineers as well as important connectors of energy flow between the intertidal zone and the adjacent marine and terrestrial environments, being predated by both marine and terrestrial ...
Industrial activated sludge exhibit unique bacterial community composition at high taxonomic ranks
(Elsevier, 2013-04-17)
Biological degradation of domestic and industrial wastewater by activated sludge depends on a common process of separation of the diverse self-assembled and self-sustained microbial flocs from the treated wastewater. ...
High-temperature and high-pressure ethylene polymerization using a cationic activated metallocene catalytic system
(2008)
Background: Normally, olefin polymerization via metallocene-based catalysis occurs under mild conditions. However, most technology developed for polyolefin production is designed for more severe temperature and pressure ...
THE CAZA-NANO GAME AND THE TEACHING OF NANO-RELATED CONCEPTS: LUDIC ACTIVITIES AT THE HIGH SCHOOL
(Univ Nacl Colombia, Fac Sci, 2017-03-01)
The topics of nanoscience and nanotechnology (N&N) are present in the media and in the everyday life of society. However, their teaching continues to pose major challenges. In Brazil, the educational proposals that deal ...
