Abperleffekt, m. water-repellent effect, abpflucken, v.t. pick, pluck, gather, abplatten, v.t. flatten. — abgeplattet. p.a. flattened, oblate. [Pg.7]

There are basically two types of collector molecules ionizing and nonionizing compounds. The former dissociates into ions in water, while the latter does not. Ionizing collectors are classified in accordance with the type of ion (anion or cation) that causes the water-repellent effect in water. [Pg.197]

The blood-sucking suppressing effect of various mosquito coils was also investigated in a field test by volunteers in district A located in the suburbs of Bangkok. As a result, high repellent effect of 80% compared with the control was... [Pg.20]

In a house on Lombok Island in Indonesia, a paper emanator impregnated with 200 mg of Metofluthrin exhibited repellent effects of 80% or greater against C. quinquefasciatus and Anopheles mosquitoes over a period of 4 weeks [6]. In addition, in outdoor conditions on Lombok Island, it exhibited superior repellent effects against C. quinquefasciatus as well as Anopheles balabaciensis and An. sundaicus, which are vector mosquitoes for malaria [7]. [Pg.214]

The linear free energy relationship has been observed in large number of cases. The applicability of the relationship is quite poor for orthosubstituents because these substituents exert not only electron-attracting or electron repelling effect but also a steric effect which usually leads to <... [Pg.200]

The repellent effect depends on hunger, as in female elk (Andelt etal, 1992) and less-preferred plants are better protected by predator urine odors (Swihart etal, 1991). [Pg.402]

Arnould, C., Malosse, C., Signoret, J.-P., and Descoins, C. (1998). Which chemical constituents from dog feces are involved in its food repellent effect in sheep Journal of Chemical Ecology 24,559-576. [Pg.431]

Another problem lies in the ovedap of repellent—toxicant definition, in that many toxicants are known to have repellent effects (43). Pyrethrins are... [Pg.118]

FIGURE 3.5 One possible explanation why lone pairs have a greater repelling effect than atoms. A lone pair is less restrained than bonding pairs and so takes up more space the bonding pairs and their atoms move away from the lone pair in an attempt to lower the repulsion they experience. [Pg.252]
