Analysis of soil compaction and furrow depth from planter row unit
… and a single-point laser sensor to measure field furrows under actual operating conditions. This technique assesses the depth and distribution of furrows. X-ray CT can identify and quantify soil beneath furrows compacted by the planter row unit's wheels and other contacting components, thereby …

Studies of deep-sea sedimentary microtopography in the North Atlantic Ocean
… formed in sandy muds and parallel to the flow), furrows (spacings of tens to 100's of meters, formed parallel to the flow and presently either erosional or depositional), and regular sediment waves (spacings of a few kilometers, now found oblique to the flow and migrating either upstream or …

Cell Topology Change by the Physical Engagement of Neighboring Cytoskeletal Networks
… and then bend downward to coat the nascent furrows. Concomitantly, the myosin borders become restricted to the furrow base. These observations let us hypothesize both networks antagonize each other through physical interaction. Indeed, increasing or decreasing myosin contractility resulted …

SUBSURFACE DRIP IRRIGATION AND UREA PHOSPHATE USE IN VEGETABLES ON CALCAREOUS SOILS.
… (Brassica oleracea var. capitata L.), 1982 fall. Furrows received a preplant application of phosphorus (P) at a rate of 100 kg P₂O₅/ha. Urea phosphate (UP) (17-44-0) solution was injected twice in drip lines during the growing season to give a total rate of 100 kg P₂O₅/ha on cabbage and 50 kg …

A King and a Prince Among Pioneers: Edward and John A. Creighton
… vast sums of money. His work-hardened hands, the furrows in his yet youthful brow and the squint lines about his eyes bespoke the outdoor toil which won his fortune. That toll to a greater or lesser extent helped insure the success of every major venture of the mid-Nineteenth. Century pertinent to …

The Use of Veld Restoration Techniques for Rehabilitating Degraded Waterberg Mountain Bushveld in Lapalala Wilderness Reserve, Limpopo Province
… the contour, allowing surface water to flow into furrows and penetrate the ground. Secondly, while the natural seedbank may provide seeds for pioneer plants to establish in a favourable environment with increased moisture and loose soil, the natural succession process is slow. To accelerate …

Soil erosion and conservation potential of row crop farming in mountainous landscapes of South Korea
… system induces preferential infiltration in furrows and planting holes due to its topography and the impermeable covers, but that the impact on flow processes in the soils is relatively small compared to the impact on runoff generation. To identify the patterns of overland flow and the …

Flow and transport processes as affected by tillage management under monsoonal conditions in South Korea
… head gradients induced lateral flow from furrows to ridges. Under monsoonal conditions, soil was fully saturated and down slope lateral flow occurred in the coarse textured topsoil. The dye tracer experiments showed that matrix flow dominated in the sandy topsoil. Lateral funnel flow above …

Bitesize bundles F-actin and influences actin remodeling in syncytial Drosophila embryo development
… for the formation of stable pseudo-cleavage furrows that prevented spindle collisions and nuclear fallout prior to cellularization. While previous studies focused on Btsz isoforms containing the Moesin Binding Domain (MBD), we found that isoforms lacking the MBD also function in actin …

Morphology and systematics of the adult females of the genus Lecanodiaspis (Homoptera: Coccoidea: Lecanodiaspididae)
… spiracles with 5-locular pores in the spiracular furrows; fleshy spiracular setae anteriorly and posteriorly; seven transverse rows of multilocular pores on the abdomen; dorsal anal plates, and anal ring with eight to ten setae; dorsum and venter with numerous 8-shaped and simple pores, with …

Budget and fluxes of nitrogen in mountainous agroecosystems in a summer monsoonal climate under intensive land use
… seepage water decreased similarly for ridges and furrows during the entire growing season, we conclude that the PE mulch had no significant effect on 15N retention in soil and on nitrate concentration in seepage water and did therefore not effectively protect the fertilizer in the ridges from …

Imaging skin structures for health, body mapping, and identification (under the Tucson Skin)
… Microreliefs are the fine micrometer scale furrows and ridges that appear like irregular geometric patterns on the skin surface; often, the intersection of the microrelief lines are at the outlets of the sweat ducts, which are used to regulate body temperature. The superficial vasculature is …

High speed geological boundary layer flows
The following work is an investigation of high speed boundary layers in geological flows. In particular, it focuses on meteorite impact structures of the Martian double-layer ejecta (DLE) type and the Mount St. Helens eruption of 1980 which was hypothesized to be an underexpanded jet originally by …
