Flight speeds of swifts (Apus apus): seasonal differences smaller than expected.
We have studied the nocturnal flight behaviour of the common swift (Apus apus L.), by the use of a tracking radar. Birds were tracked from Lund University in southern Sweden during spring migration, summer roosting flights and autumn migration. Flight speeds were compared with predictions from flight mechanical and optimal migration theories. During spring, flight speeds were predicted to be hi...
متن کاملAre Ours Really Smaller than Theirs? Are Ours Really Smaller than Theirs?
The claim is often made that functional programs are \more" expressive than their imperative counterparts. This paper examines this claim using a particular measure of (i) program length and (ii) programming language \level" (a measure of expressive power) both from the work of Halstead on software metrics. This paper was presented at the 1996 Glasgow Functional Programming Workshop, held in Ul...
متن کاملAre there species smaller than 1 mm?
The rapid advance in genetic sequencing technologies has provided an unprecedented amount of data on the biodiversity of meiofauna. It was hoped that these data would allow the identification and counting of species, distinguished as tight clusters of similar genomes. Surprisingly, this appears not to be the case. Here, we begin a theoretical discussion of this phenomenon, drawing on an individ...

متن کاملPresenting a food in multiple smaller units increases expected satiety
Presentation of the same amount of a food in multiple smaller units ('segmentation') has been shown to reduce food intake and increase estimates of the amount of food consumed. However, this effect has been demonstrated for ad libitum food intake only. In the majority of cases, meals are not consumed ad libitum, but are pre-selected and consumed in their entirety, Expected satiety (ES; the anti...
