Synthesis, characterization, and thermal behavior of transition metal oxamates, M(NH(2)C(2)O(3))(2)center dot nH(2)O (M = Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(II)), as well as the thermal behavior of oxamic acid and ...
Thermal behaviour of succinic acid, sodium succinate and its compounds with some bivalent transition metal ions
(Elsevier B.V., 2010-03-10)
Characterization, thermal stability and thermal decomposition of transition metal succinates, MC(2)H(4)C(2)O(4)center dot nH(2)O (M = Mn(II), Fe(II), Co(II), Ni(II), Cu(II), Zn(II)), the thermal behaviour of succinic acid ...
Histopathology of Rhipicephalus sanguineus (Acari: Ixodidae) ticks fed on resistant hosts
(Springer, 2010-02-01)
Histological features of Rhipicephalus sanguineus ticks fed on dog, a non resistant host, and on guinea pig, a resistant host, were compared. Unfed ticks and ticks from each host species were collected during first and ...
Influence of Fungal Contamination on Substrate Carrying by the Leafcutter Ant Atta sexdens rubropilosa (Hymenoptera: Formicidae)
(California State University, 2009-01-01)
Toxic baits are the most used method for controlling leafcutter ants and are usually composed of a mixture of dehydrated citric pulp with an active ingredient dissolved in soy oil. In this study, we evaluate if filamentous ...
When Basking Is Not an Option: Thermoregulation of a Viperid Snake Endemic to a Small Island in the South Atlantic of Brazil
(Amer Soc Ichthyologists & Herpetologists, 2012-09-20)
It is broadly accepted that snakes are able to regulate their body temperature (T-b) behaviorally, but fundamental differences in this ability have been suggested to exist between temperate and tropical species. Herein, ...
Synthesis, characterization and thermal behaviour of solid-state compounds of 4-methoxybenzoate with some bivalent transition metal ions
(2005-05-18)
Solid-state M-4-MeO-Bz compounds, where M stands for bivalent Mn, Co, Ni, Cu and Zn and 4-MeO-Bz is 4-methoxybenzoate, have been synthesized. Simultaneous thermogravimetry-differential thermal analysis (TG-DTA), differential ...
CERAMIC MATERIAL FROM SEWAGE SLUDGE AS SUPPORT MATERIAL SUPPLY WATER FILTRATION
(Trans Tech Publications Ltd, 2012-01-01)
This study shows a possibility of using municipal sewage sludge after thermal treatment in the production of a filtering material to water treatment. Due to the fast urbanization and implementation of high standards for ...
Comparison of the biological behavior of wollastonite bioceramics prepared from synthetic and natural precursors
(2008-01-22)
Wollastonite bioceramics prepared from synthetic and natural precursors were implanted in rats in bone and subcutaneous tissues. The implant sites were excised after 7, 30 and 120 days, fixed, dehydrated, embedded in ...
