Future potential applications and benefits of Nano Dimension's side-mounting technology include printing a horizontal ground layer on the z-axis, enabling the printer to produce higher performance antennas or multiple antennas with varying voltages within the board.
* loss of ground layer vegetation, including orchids to digging rats;
In oil paintings there can be physical deterioration such as weakening of the canvas, tears, holes, losses in the ground layer, cracking, cupping, flaking and shrinking of the paint layer; chemical damage such as darkening of the varnish and colour changes; biological factors such as attacks by fungus, silverfish, termites, cockroaches or rats; and human factors such as negligent storage, packaging, transportation, display, or vandalism.
Fog is a phenomenon due to lots of water droplets or ice crystals suspended in the air of the ground layer, which makes horizontal visibility decline to 1 km or less [1].
However, the higher slopes of the hill will be warm, as the low circulation mixes the ground layer with neighboring warm air.
The species attrition hypothesis, originally applied to seed banks (Bond, 1984) and extended to predicting the response of ground layer species richness and traits to woody encroachment in oak woodlands (Taft, 2009), provides a framework for examining changes in shrub and sapling-encroached native grasslands.
Not so Eastaugh's analysis, which identified the pigment titanium white--unavailable in 1914--in the ground layer of the picture.
At the same time, the position and number of grounded via holes distributed between the antenna ground layer and the system PCB board are also a key factor that affects the antenna performance.
The aquatic layer was comprised of submerged or floating plants; the ground layer was restricted to bryophytes; the herbaceous stratum was characterized as vegetation less than 1 m in height; the shrub layer was characterized as vegetation with diameter at breast height (DBH) [less than or equal to] 4 cm; the tree layer was characterized as vegetation with living stems > 4 cm DBH.
In this paper, parasitic capacitance of integrated EMI filter is effectively cancelled by using modified ground layer. The simplified equivalent circuits were derived to demonstrate the cancellation mechanism, and main influence factors in implementation were also investigated.
In early stage on designing proposed WPD, a ground layer was introduced where this design only satisfied for narrow band operating frequency.
