While the incidence of extreme poverty fell dramatically in China over 1980–2001, progress was uneven over time and across provinces. Rural areas accounted for the bulk of the gains to the poor, though migration to urban areas helped. Rural economic growth was far more important to national poverty reduction than urban economic growth; agriculture played a far more important role than the secon...

The surface V3 of the denuded corneal stroma was separated into the anterior and posterior segments; the swelling ratio of each was compared under zero pressure. In the rabbit, cat, and bovine corneas, the anterior segment was less hydrophilic than the posterior one, in both the central and peripheral regions. In the rabbit cornea, the swelling ratio of the posterior segment was significantly l...

Abstract: This research is aimed at improving accuracy of stereolithography (Rapid prototyping) system. The objective of this paper is to detect the flatness of freeform liquid surface. The principle of measurement is performed by obtaining grating image of total reflection from freeform liquid surface. The detection is performed by two steps, coarse detection and fine one. Coarse detection is ...

in order to study the effect of elevation on quantitative and qualitative characteristics of the humid forests of guilan shafaroud, series 17, 16 and 7 were selected that fall in to three height classes; class 1 (‏less than 500 m), class 2 (‏500 – 1000 m) and class 3 (‏1000 – 1600 m). in height class 1, 2 and 3 sample plots were determined as 4, 15 and 20 respectively and each sample plot was 0...

Key words Structure was assessed in uneven-aged stands of loblolly (Pinus taeda) and shortleaf pine (P. echinata) that were subjected to prescribed winter burns on cycles of 0, 3, 6, and 9 years. Vegetation assessments were made in late summer of 1990, 10 years after a single hardwood control treatment (basal injection of nonpine woody plants >2.5 cm in ground-line diameter with TordorP 101 R);...

Available evidence indicates that pulmonary diffusion is distributed in a non-uniform manner throughout the lung; the pertinent literature was reviewed briefly in the preceding paper of this series (1). Conventional methods for measuring the pulmonary diffusing capacity do not allow a quantitative assessment of this non-uniformity, and, in the presence of uneven diffusion, may yield erroneous v...

We consider a finite-difference approximation to the Cauchy problem for a firstorder hyperbolic partial differential equation using different mesh spacings in different portions of the domain. By reformulating our problem as a difference approximation to an initial-boundary value problem, we are able to use the theory of H. O. Kreiss and S. Osher to analyze the L3 stability of our scheme. 0. In...

This paper presents a novel gait generation approach which combines a reactionary and a central pattern generator (CPG) system. The former couples isolated leg controllers by simple gait generation rules that ensure static stability and produce a continuum of gait patterns across the full speed range. The CPG system is based on six coupled oscillators and complements the reactionary system to f...

The use of uneven-aged silviculture has increased markedly in the past 20 years. This is especially true in the southern United States, where the use of clearcutting and planting is often viewed as a practice whose emphasis on fiber production results in unacceptable consequences for other values, such as those that benefit from maintenance of continuous forest cover over time. Public lands in ...

The issue of economic globalization and global economic change has been a subject of immense academic research in the past two decades. The Janus face of economic globalization, however, continues to obfuscate our understanding of its complex processes and alleged geographical outcomes. In this paper, I aim to re-present the indispensable role of geography in conceptualizing economic globalizat...
