the foraging behavior of a natural enemy is greatly affected by temperature. the influence ofdifferent constant temperatures on the functional response and prey consumption of the mated female ofneoseiulus barkeri hughes on nymphal stages of tetranychus urticae koch was evaluated. four ambienttemperatures (20, 25, 30 and 35 â± 1â°c) and six prey densities (2, 4, 8, 16, 32 and 64 individuals) we...

The n-queens problem is to determine Q(n), the number of ways place n mutually non-threatening queens on an n×n board. We show that there exists a constant α=1.942±3×10−3 such Q(n)=((1±o(1))ne−α)n. α characterized as solution convex optimization in P([−1/2,1/2]2), space Borel probability measures square. chief innovation introduction limit objects for configurations, which we call queenons. The...

The surface tension of 1,2-dimethyl-3-N-hexadecyl imidazolium tetrafluoroborate (Im BF4) as a function of concentration has been measured. Between 10−5 and 4× 10−4 mol/L, the surface tension decreases with increasing imidazolium concentration. Aggregate formation appears to occur at a concentration near 4× 10−4 mol/L for temperatures between 50 and 75 ◦C. Small angle neutron scattering measurem...

BACKGROUND Biofilm formation is a major pathogenic factor in different bacteria such as Pseudomonas aeruginosa. A number of studies have reported that bacterial biofilms show different levels of antibiotic resistance. In order to re-sensitize the bacterial biofilms to antibiotics, biofilms should be dispersed. OBJECTIVES In this study, the effect of n-butanolic Cyclamen coum extract in combin...

Elevated C-terminal fibroblast growth factor 23 (C-FGF23) concentrations have been reported in Gambian children with and without putative Ca-deficiency rickets. The aims of this study were to investigate whether i) elevated C-FGF23 concentrations in Gambian children persist long term; ii) they are associated with higher intact FGF23 concentrations (I-FGF23), poor iron status and shorter 25-hydr...
