Second, the machining process was divided into three parts including sparking, horizontal feeding and vertical feeding.
The neck may have been used for increasing the horizontal feeding range (Martin 1987) or for high browsing (Bakker 1986; Paul 1988).
Although some authors favoured nearly vertical neck postures and specialized high-browsing [ 6, 7], others have argued that increased horizontal feeding range has been the primary function of the neck and that the vertical range was only limited [ 8, 9].
The long necks of sauropods (Fig. 5) are either interpreted as a means for high browsing (e.g. Bakker, 1987; Paul, 1987, 1998) or for increasing the horizontal feeding range (e.g. Martin, 1987; Mateus, Maidment & Christiansen, 2009; Seymour, 2009 a, Preuschoft et al., in press).
Most horizontal balers are fed by conveyor belt, cyclone or forklift for achieving continuous feeding.
In most simple machines the movement of the cutter may be controlled by the manual operation of transverse, horizontal, and vertical feeds.
To our knowledge, this study is the first to investigate the microbial dynamics of the gut microbiota in house fly larvae and their horizontal transfer through feeding.
We are interested in (1) the microbial dynamics of the gut microbiota in house fly larvae and (2) their horizontal transfer through feeding.
Nevertheless, these larvae are exposed to horizontal transmission via feeding (reviewed by Chen et al. [ 2]).
The Rotorvane consists of a horizontal barrel with a feed hopper at one end and a perforated plate at the other.
During habituation, vertical activity was increased in the 2 h bin preceding scheduled feeding (P = 0.006) and there was a trend for increased horizontal activity preceding scheduled feeding (P = 0.094).
