Some have a round cross section while others have a more square or rectangular shape. Approximately 50,000 F1 flies were scored and 84 lines with bristle phenotypes were established.

Figure 5.16. Therefore, only milk bottles from bottle suppliers and filling companies which support the project are directed to the bottle-to-bottle recycling process. The passages introduce two characters of different gender (i.e., Elizabeth and the male lifeguard), who are subsequently referred in the target sentences (a) to (d) using either a pronoun or a repeated noun. However, innovations are also produced in stable environments, where an animal discovers a new method of exploiting the environment, an example of niche construction. If one animal has performed the novel behavior, then it is obviously possible for such a novelty to appear in the population. This is consistent with the thoughts of the original observers and the findings of a study of captive blue tits (Sasvari, 1979) but not with studies of black-capped chickadees (Sherry and Galef, 1984, 1990). There was, however, a great deal of variation between individuals in their learning ability in the presence of knowledgeable tutors because significant age- and sex-biased social learning was observed. Two quantitative models of the cultural transmission of bottle opening behaviours were compared: a logistic model representing the cumulative bottle opening sites both in Belfast and the whole of the UK and a linear wave-of-advance model representing the progressive spread of bottle opening over time from its presumed original location of Swaythling.

Second, each bird might, independently, discover this feeding option.

Within seconds (she1/Elizabeth1) sank into the pool.

[3] This leads to the other main issue associated with anaphora resolution, which concerns the nature of the discourse representation required to support the process. As plastics technology advances, partial replacement of glass containers by plastics has occurred in various liquid food packaging applications including milk (INEOS Polyolefins 2007).

However, the antecedent probe recognition technique has not been so successful in demonstrating immediate reactivation of antecedents after reading a pronoun anaphor (Gernsbacher 1989). Plastic Bottles; 12 to 16 oz Plastic Bottles; 18 to 32 oz. Because glass is impermeable, the milk inside won't get contaminated by the bottle, appealing to consumers who are highly conscious of what goes into their food and drink. A key factor with one-way recyclables is the recycling rate: In the US, only about 30-35% of HDPE bottles are recycled.

The studies of chickadees suggested that social learning was unlikely to have occurred and these equivocal findings prompted a theoretical analysis (Lefebvre, 1995) to examine the likely causes of the spread of the milk bottle opening behaviour, using the data from the original studies (Fisher and Hinde, 1949; Hinde and Fisher, 1951). This view received only partial support from studies of black-capped chickadees because when birds were presented with open or closed bottles of milk they were no faster at learning to open them in the presence of knowledgeable tutors in comparison to other naïve individuals (Sherry and Galef, 1984, 1990). To identify novel genes involved in Notch signaling pathway, we performed a genetic screen for genes on the 3R chromosome that affect the development and specification of Drosophila external sensory organs, a process regulated by the Notch pathway (Jafar-Nejad et al., 2005). [9] This sniffing device is able to detect potential migrants, such as solvents or other volatile substances, which might be introduced into the recycling process. By reading the bar code the vendors are able to separate bottles from these two manufacturing companies from other milk bottles which are rejected.

Glass gives a vintage, old-style feel, while plastic suggests more about convenience.

Empty Plastic Bottles Milk Container, 12 oz Bottles Mini Milk Jugs Juice Water with Lids 12 Pk. Note: HTML is not translated! Typical 1-liter bottle dimensions for pasteurized milk are 89 mm (base diameter), 35–40 mm (neck diameter) and 267 mm (height); and for sterilized milk 89 mm (base diameter), 26 mm (neck diameter) and 294 mm (height). Glass milk bottles have traditionally been reusable while light-weight plastic bottles are designed for single trips and plastic recycling. Hence, readers immediately respond to the anomaly with sentence (b) as compared with sentence (a) above.


The short lives of these small birds combined with the increasing dependence on supermarket purchase of milk—and low-fat milk, at that—mean that the behavior is rarely observed in modern Britain. In Swaythling, a village in southern Britain, in 1921 the first observation was made of a blue tit opening milk bottles left outside homes and drinking the cream. They found that recognition was enhanced immediately following criminal as compared with cat. In primates, there is a positive correlation between brain size and social learning abilities and yet the same relationship is much less clear in birds and so blue tits and other Parids offer a useful opportunity to explore this relationship because blue tits are faster learners than closely related marsh tits (Poecile palustris). In summary, evidence on the time course of anaphora resolution, both from antecedent reactivation studies and from studies that tap into the consequences of resolution, indicate that it occurs in tandem with other more basic sentence comprehension processes. A fraction of pasteurized, ultrapasteurized and sterilized milk is sold in glass bottles today in several countries including Great Britain, Sweden, Greece, Cyprus, etc. Several milk bottles were piled at the curb. In 2002 the following project was started in Northern Ireland.37 Milk bottles were recovered by a deposit system and were subjected to a bottle-to-bottle recycling process. The HDPE milk bottles were provided by only two bottle manufacturers, which are integrated into the project.

This discrepancy in the findings from the two techniques leads to the conclusion that anaphora resolution is a two-stage process. The intended application for the recycled material was again bottles for fresh milk with short time storage under refrigerated conditions.

They presented readers with passages such as the following: Elizabeth1 was an inexperienced swimmer and would not have gone in if the male lifeguard2 had not been standing by the pool. 1) (Aplin et al., 2013). They're also free of BPA that's found in some plastic containers. Use of Food contact materials is required: potential food contamination is prohibited. The second way of investigating the time course of resolution is to examine when antecedent information is incorporated into the interpretation of the sentence containing the anaphor. One approach is to record precisely when an antecedent is reactivated after encountering an anaphor.
