16 The male is a little larger than the female and has very bright orange ventral fins when in breeding colouration.

17 Blindness is also a major handicap to the recognition of a potential mate, as is deviant colouration.

18 "The finding that immune responsiveness and parasite intensity correlates with colouration suggests that melanin-based colouration could play a role in sexual selection, " explains Ms Jacquin.

19 The contents was determined by thin layer scanner with double wavelength after the dithizone colouration.

20 Through analyzing the properties of PVC extruded materials, the main factors causing the colouration of PVC extruded product were investigated.

21 The story goes that our ancestors were first attracted to ripe, red fruit, then co-opted this attraction for sexual purposes, developing pronounced red colouration on the genitals and lips.

22 In this paper the working principles and process technology of the electrolytic colouration operation tor fhe automobile window frames made of aluminium alloy are presented.

23 However, there are exceptions: animals which are dangerous to eat (e.g. wasps) advertise with warning colouration.

24 Conclusion:The new assay showed wide linearity, good recovery and stable colouration and is a specific indication for distinguishing tuberculous effusions from non-tuberculous effusions.

25 They added that the canids were "larger, more slender and sometimes with a more whitish colouration".

26 In fact, the depiction of the burning clouds was only one brush of rosiness in the bright-colored and massive colouration in the whole piece of literature.

27 Methods: The traditional separation method and cribration with Salmonella colouration flat plate.

28 Spectrophotometry is one of the most widely used methods for determination of trace Pt,[] the rhodanine compounds are excellent colouration agent.

29 The vibration types and existence format of water in the emerald are revealed. Further, the colouration mechanism of the emerald is discussed.

30 Conclusion: The disservice of Salmonella mainly from the meat products, through the cribration with Salmonella colouration flat plate can reduced the quantity of the work.

36 The colouration of Aluminum film with mirror face was introduced with the addiction of proper amount of activating agent in metallographic mirror bright coating dye bath.

37 One of the direct reasons for bad colouration of Feizixiao is that the chlorophyll content in Nuomizi fruit peel is much lower than that of Feizixiao during the ripening period.

38 The developments of technologies for plastics colouration with colour master - batches were mainly introduced.
