2-Ethyl-N-[(5-nitrothiophen-2-yl)methylidene]aniline
(WILEY-BLACKWELL, 2011)
In the title compound, C13H12N2O2S, the dihedral angle between the benzene and thiophene rings is 36.72 (8)degrees. An intermolecular C-H center dot center dot center dot pi interaction contributes to the stability of the ...
The rectifying developable and the tangent indicatrix of a curve in Galilean 3-space
(SPRINGER, 2011)
We study the singularities of Galilean distance and Galilean height functions intrinsically related to Frenet frame along a curve embedded into Galilean space. We establish the relationships between singularities of the ...

(ELSEVIER SCIENCE INC, 2011)
Background and Aims. The present study investigated the effects of a 900-MHz electromagnetic field (EMF) for 2 h/day for 45 days on lymphoid organs (spleen, thymus, bone marrow), polymorphonuclear leukocytes (PMNs) and ...
Effects of host species, stage and size on the sex ratio and clutch size of the parasitoid, Dibrachys boarmiae (Walker, 1863) (Hymenoptera: Pteromalidae)
(CAMBRIDGE UNIV PRESS, 2011)
Effects of host species, stage and size on clutch size and sex ratio of the gregarious, idiobiont ectoparasitoid Dibrachys boarmiae were investigated at 25 +/- 2 degrees C and 70 +/- 5% relative humidity. The greater wax ...
