Identifying lateral spread fissures with ground penetrating radar in the New Madrid seismic zone
… the size, shape and orientation of relict lateral spread fissures created during the New Madrid earthquakes of 1811 and 1812. Aerial imagery was used to locate regions with elongate vented sand indicative of large-scale fissures. Five GPR surveys were conducted over these areas and …

Penumbral Distributions For High-energy Radiotherapy Photon Beams: Experimental And Theoretical Determinations
… these two distributions is associated with the lateral spread of the second electrons and is strongly dependent on the beam energy and electron density of the medium of interaction.;Specially-designed cylindrical ionization chambers of varying inside diameters were used to determine the primary …

Identification of seismically-induced landslippage along Crowley's Ridge, southeast Missouri and northeast Arkansas
… the feasibility of recognizing landslide and lateral spread features using topographic algorithms. The algorithms use drainage and topographic keys to recognize anomalous site characteristics typical of various landslide forms, including lateral spreads, slumps and retrogressive slump …

Effect of polyacrylamides on the physical properties of some light-textured soils.
… events. There was clearly only minimal lateral spread of the water in these coarse sands. However, by applying small concentrations of polyacrylamide or ‘PAM’ in the irrigation water, the crops seemed to do better. Furthermore the timing of irrigation events appeared to be more flexible …

The Effects of Basin Slope and Boundary Friction on the Character and Plunge Location of Hyperpycnal Flows Entering a Laterally Unbounded Basin
… assumption in these studies is that the flow is laterally confined. These studies allow the flow to plunge only in two directions, the horizontal x-direction and the vertical z-direction. The goal of this study is to determine if there is observable plunging of hyperpycnal flows in the lateral …

Uptake of Sulphur-35 by pasture plants from different depths in two Canterbury soils under field conditions : A dissertation submitted in partial fulfilment of the requirements for the Degree of Bachelor of Agricultural Science (Honours) in the University of Canterbury
… in s³⁵ uptake were examined, and , (3) The lateral spread of uptake of sulphur by plants from a source of application was assessed.

EPOLLS: An Empirical Method for Prediciting Surface Displacements Due to Liquefaction-Induced Lateral Spreading in Earthquakes
In historical, large-magnitude earthquakes, lateral spreading has been a very damaging type of ground failure. When a subsurface soil deposit liquefies, intact blocks of surficial soil can move downslope, or toward a vertical free face, even when the ground surface is nearly level. A lateral spread …

Structure of Cross-Bridges in Vertebrate Skeletal Muscle Activated by Photolysis of Caged Ca2+
… in relaxed fibers, while it broadens six-fold laterally. The 1/430 Å-1 meridional spot is present during contraction but markedly weakened. The 1/215 Å-1 meridional spot is weak or absent. These results are consistent with time resolved X-ray diffraction data on the periodic structures within …

Caucasian clover establishment in the high country and grazing responses in ryegrass/white clover lowland pasture
… development of Caucasian clover and the greatest lateral spread of rhizomes. However, all plants strip and sod seeding developed rhizomes after nine months. Plants established by broadcasting were small with few rhizomes in the first season. The higher fertiliser rate improved establishment and …

Evaluating soil pressures on a deep foundation element due to liquefaction-induced lateral spreading
… system, and the kinematic forces induced by the lateral spreading ground. Both must be analyzed in practice to design a bridge foundation, or other foundation type, subject to seismic forces and potential lateral spreading-induced pressures. The kinematic loadings on a large, rigid caisson due to …
