Attacks aerial

Acharya, L. and Fenton, M. B. (1992). Echolocation behavior of vespertillionid bats (Lasiurus cinereus and Lasiurus borealis) attacking aerial targets including arctiid moths. Canadian Journal of Zoology IQ 1292-1298. [Pg.274]

The addition of organometallics leads to alkyl- or aryl-dihydro-TPs and can be followed by rearomatization. After the attack of phenyllithium on unsubstituted TP and aerial oxidation, the 5- and 7-phenyl-TPs are isolated (72JHC1157). Methyllithium, on the other hand, gives a mixture of 5-methyl-TP and its 4,5-dihydro derivative [68DIS(B)1303]. [Pg.115]

Bergman explains why he prefers the term air acid or aerial acid to the then usual name—fixed air. In the first place, because this is only one of several kinds of air which occur fixed, and in the second place, because it is at the same time a true acid and a constant constituent of the atmosphere. Fixed air, he says, is a true acid, because it possesses a distinctly acid taste it reddens litmus ( turnsol ) it attacks caustic fixed alkalies, rendering them mild a smaller quantity of this acid than of the stronger acids saturates these alkalies and renders them crystallizable and less soluble it makes the volatile alkali (ammonia) more fixed, less odorous and penetrating and causes it to crystallize when it just saturates quicklime, it deprives it of its solubility and acrimony and causes... [Pg.477]

Two measures to reproduce the key aspects of the enzyme have had some success to use an aromatic thiol and to block attack on the iron by building organic frameworks over the metal. Other approaches, illustrated in Fig. 4.10, include substituting iron with manganese, which is less sensitive to aerial oxidation, and to tether a cyclodextrin to the porphyrin so that the organic substrate could be positioned correctly for oxidation. [Pg.122]

Apart from its thermochemical and catalytic activities, it. seems very probable that pyrites can assist in the oxidation of coal in a purely mechanical manner as well, inasmuch as it tends to swell on oxidation and thus to increase the mechanical disintegration of the coal, thereby exposing larger surfaces to aerial attack.4... [Pg.69]

Colored Low-Target Flare, M50 was developed in 1944 when mass concentration of planes for ni t aerial attacks had grown so heavy that some method of identifying group leaders in the air was required. This flare was towed by a cable behind the plane of each leader, with each leader having a different colored flare. Burning time was five minutes and candlepower 20000 to 225000 (Ref 2, p 316)... [Pg.446]

Mealy bugs (Planococcus spp.) are also plant fluid sucking insects which sometimes attack kava aerial parts and roots. Severe infestation can lead to defoliation, and in the case of root infestation, to a general unsightly plant appearance. [Pg.36]

Gradually, all ships conformed to the neutral grey shades that had been typical of early World War 1. In spite of the not inconsiderable success of dazzle painting, no attempt was made to reintroduce it, at least not in its original form and not on the majority of British mercantile auxiliaries. From April 1941, aware of the threat of aerial attack. Admiralty recommendations for merchant ship colouring called for the use of MSS (Merchant Ship Sides) mid-grey and MSI) (Merchant Ship Decks) dark grey. [Pg.43]
