Ideal characteristics for

DDT met all but one of Muller s ideal characteristics for an insecticide. It was a cheap, contact poison without objectionable odors. It was stable in air and light. Because it was so powerful, extremely small doses could be used. And finally, it dissolved so poorly in water that warm-blooded organisms absorbed only traces of it. The fact that DDT dissolves well in oils did not seem dangerous only later did scientists realize that, because DDT accumulates in animal fat and mammals milk, it becomes increasingly more concentrated in predator species as it moves up the food chain. DDT s only failing, as far as Muller s original conception was concerned, was that it did not kill immediately. [Pg.154]

It is clear from the preceding discussion that the transition metals have the ideal characteristics for catalytic activity, both because of their pronounced but relatively moderate directional binding, and because... [Pg.17]

A new set of ideal characteristics for the desensitizing agent for use with RDX for producing Compn A-3 is contained in Ref 55. These characteristics are ... [Pg.335]

Form factor — Ratio between the RMS value and the average value of a periodic waveform. Form factor is another indicator of the deviation of a periodic waveform from the ideal characteristics. For example, the average value of a pure sinusoidal wave averaged over a cycle is 0.637 times the peak value. The RMS value of the sinusoidal wave is 0.707 times the peak value. The form factor, FF, is calculated as FF = 0.707/0.637 = 1.11. [Pg.15]

For the formation of solid dispersions by congealing a melt of poorly water-soluble drug and carrier, Ford recommends the following ideal characteristics for the substrate/carrier material ... [Pg.764]

No storage tank technology has all of the ideal characteristics for commercial applications. It would have to be compact, lightweight, safe, inexpensive, and easily filled. [Pg.183]

AlTUD-1, a new mesoporous, Bronsted acidic aluminosilicate with ideal characteristics for catalyst immobilization was used for the noncovalent anchoring of hydride tungsten complex [WH2(ti -OOCCH3) (Ph2PCH2CH2PPh2)2][BPh4]. The immobilization was carried out by an adsorption process in liquid phase. The new materials were characterized by several techniques spectroscopic methods (ICP-AES, FT-IR and UVA is), X-ray techniques (XPS and XRD), isothermal nitrogen adsorption and elemental analysis. [Pg.417]

The ideal characteristics for a detector are high sensitivity, low noise, linearity of response, and uniform response with respect to wavelength. [Pg.3490]

Unfortunately, the ideal SMP biomedical device has yet to be designed that meets all of the listed ideal characteristics for any given application. It is important that SMP devices be designed with these ideals and practical challenges in mind, and that the limitations of the technology are well understood to design a successful SMP device. [Pg.170]

Water possesses many of the ideal characteristics for a reaction medium- it is readily available at negligible cost, is safe and convenient to use, and has low environmental impact. [Pg.350]

The fine control over the ablation process makes another feature possible. If the etching is intermpted just before file metal is reached, a defect with a thin (several im) residual layer on the bottom can be produced, as illustrated schematically in Figure 21. It is this defect that proved to have ideal characteristics for broad characterization of organic coatings, including electrochemical impedance spectroscopy. [Pg.718]
