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 ...
Effects of thiacloprid, deltamethrin and their combination on oxidative stress in lymphoid organs, polymorphonuclear leukocytes and plasma of rats
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2011)
Deltamethrin and thiachloprid are an alpha-cyano class pyrethroid and neonicotinoid insecticide, respectively. Recently, a pesticide combining deltamethrin and thiacloprid has also been released. In the present study, the ...
Effects of a 900-MHz Electromagnetic Field on Oxidative Stress Parameters in Rat Lymphoid Organs, Polymorphonuclear Leukocytes and Plasma
(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 ...
A NOTE ON SOFT NEAR-RINGS AND IDEALISTIC SOFT NEAR-RINGS
(UNIV NIS, FAC SCI MATH, 2011)
Molodtsov introduced the theory of soft sets, which can be seen as an effective mathematical tool to deal with uncertainties, since it is free from the difficulties that the usual theoretical approaches have troubled. In ...
EVALUATION OF METAL ACCUMULATION, OXIDATIVE STRESS, BIOCHEMICAL AND HEMATOLOGICAL PARAMETERS IN SANDER LUCIOPERCA L., 1758 FROM BAFRA (SAMSUN) FISH LAKES
