Abstract:
This study investigates the evolution of different grain boundaries in two-dimensional wet foam (2D) together with the width and the roughness of the interface. The foam around the boundaries coarsened and became disordered. The level of the disorder increased with time over a range and is consistent with the results from previous studies on relatively ordered soap froths. Although the misorientation angle comprising the grain boundaries did not affect the evolution of the foam, the nature of the system boundaries had a significant effect on the degree of the disorder along the grain boundarie

Analysis has estimated the seasonal boundaries in time according to the instantaneous frequency in cycles/day and the estimations are verified with studying power spectrum of the time series. Two boundaries are obtained in each analysis over the average of yearly analysis of four years. Obtained seasonal boundaries on 16 March and 20 October are indicated as the differe

Presence-absence data for tree species in over 1000 quadrats, 10 ° 20m, on 144 transects were analysed by the divisive classificatory program TWINSPAN in order to define wet or dry monsoon forest, ecotone and savanna assemblages. A sorted table revealed that there was continuous floristic variation among these six vegetation types, although the abundance of tree species varied highly significantly between assemblages. Both wet and dry monsoon forests have higher stem densities, greater basal area, more tree species, higher litter cover and lower grass cover than surrounding savannas. Wet monso

Abstract:
Nonstationary two-dimensional filtration in a porous medium is considered, whereby part of the medium is saturated, another part is unsaturated but wet, and the remaining part is dry. The saturated/unsaturated and unsaturated/dry interfaces are free boundaries. It is shown that there exists a unique solution, and that the saturation function is continuous in the wet portion of the medium; this implies that the two interfaces are separated. Under some monotonicity-type conditions on the initial and boundary data it is shown that the free boundaries are continuous.

AbstractWet nurses in early imperial China were chosen from household slaves based on their physical and psychological conditions.

Indolent and distrusted wet nurses could be whipped or executed, but loyal and intimate ones could bring themselves and their family material and honorary rewards.

Abstract:
Physical experiments indicate that when an expanding fluid flows through a porous rock then the boundary between the wet and the dry region can be very irregular (e.g. see [OMBAFJ] and the references therein). In fact, it has been conjectured that this boundary is a fractal with Hausdorff dimension about 2.5. The (one-phase) fluid flow in a porous medium can be modelled mathematically by a system of partial differential equations, which, under some simplifying assumptions, can be reduced to a family of semi-elliptic boundary value problems involving the (unknown) pressure p(x) of the fluid (at

Consider an ontology T where every axiom is labeled with an element of a lattice (L, ≤). Then every element l of L determines a sub-ontology Tl, which consists of the axioms of T whose labels are greater or equal to l. These labels may be interpreted as required access rights, in which case Tl is the sub-ontology that a user with access right l is allowed to see, or as trust levels, in which case Tl consists of those axioms that we trust with level at least l. Given a consequence α (such as a subsumption relationship between concepts) that follows from the whole ontology T, we want to know fro

Abstract:
In this restless world, leaders face complex challenges that can be solved only by building bridges across expansive boundaries. In this second of two CCL white papers on boundary spanning, we share some success stories and outline some tactics that you can use right away to bridge boundaries in your organization.

Abstract:
We investigate whether better access to markets through an improved road network plays a role in improving firm profitability in India. We construct a district-level market access index using shapefiles of India's road network, district boundaries, and nightlight raster images and estimate the shortest driving distances for districts using the road network. Using the annual survey of industries data for India during 2001–2015, we show that market access through improved road connectivity resulted in a lower dispersion of ROA between 2001 and 2015 in India.

Abstract:
This paper tests the sensitivity of poverty indexes to the choice of adult equivalence scales, assumptions about the existence of economies of scale in consumption, methods for treating missing and zero incomes, and different adjustments to handle income misreporting. We also perform sensitivity analysis to the use of different poverty lines and poverty indexes, which are issues that have been much more explored in the literature. The sensitivity analysis is applied to household survey data from 17 Latin American countries, which include 92% of the population in the region. By varying these pa

Abstract:
Portable X-ray fluorescence (pXRF) technology collects geochemical data at a fraction of the cost of traditional laboratory methods. Although the pXRF spectrometer provides concentrations for 41 elements, only a subset of these elements meet the criteria for definitive, quantitative, and qualitative data. However, high-quality pXRF data obtained by correct application of analytical protocols, can provide robust insight to stratigraphy and sediment characteristics that are often not observed by, for example, visual core logging, grain size analysis, and geophysical logging. We present examples

Abstract:
The Scott and Norma Matheson Wetlands Preserve (“the Preserve”) is a rare riparian environment in the Colorado River corridor and a popular recreation area adjacent to Moab, Utah. We undertook this study to better understand the hydrologic system of the wetlands and a brine layer that underlies fresh water within the boundaries of the Preserve. We calculated a water budget for the Preserve using field measurements, remote sensing, and the United States Geological Survey (USGS) Soil-Water Balance Model, version 2, for water years 2017 to 2022. We used transient electromagnetic (TEM) surveys, el

Abstract:
The McMurdo shear zone (MSZ) is strip of heavily crevassed ice oriented in the south-north direction and moving northward. Previous airborne surveys revealed a chaotic crevasse structure superimposed on a set of expected crevasse orientations at 45 degrees to the south-north flow (due to shear stress mechanisms). The dynamics that produced this chaotic structure are poorly understood. Our purpose is to present our field methodology and provide field data that will enable validation of models of the MSZ evolution, and here, we present a method for deriving a local velocity field from ground pen

Abstract:
In nature, ice frequently contains dissolved solutes or entrapped particles, which modify the microstructure and mechanical properties of ice. Seeking to understand the effect of particle shape and geometry on the mechanical properties of ice, we performed experiments on ice containing 15 wt% silica spheres or rods. Unique to this work was the use of 3-D microstructural imaging in a -10ºC cold room during compressive loading of the sample. The silica particles were present in the ice microstructure as randomly dispersed aggregates within grains and at grain boundaries. While cracks originated
