Development and evaluation of a collision avoidance system for supervisory control of a micro aerial vehicle

REA Auditado

Recent technological advances have enabled Unmanned Aerial Vehicles (UAVs) and Micro Aerial Vehicles (MAVs) to become increasingly prevalent in a variety of domains. From military surveillance to disaster relief to search-and-rescue tasks, these systems have the capacity to assist in difficult or dangerous tasks and to potentially save lives. To enable operation by minimally trained personnel, the control interfaces require increased usability in order to maintain safety and mission effectiveness.

Effects of proactive population-based nephrologist oversight on progression of chronic kidney disease: a retrospective control analysis

REA Auditado

Abstract Background Benefits of early nephrology care are well-established, but as many as 40% of U.S. patients with end-stage renal disease (ESRD) do not see a nephrologist before its onset. Our objective was to evaluate the effect of proactive, population-based nephrologist oversight (PPNO) on chronic kidney disease (CKD) progression. Methods Retrospective control analysis of Kaiser Permanente Hawaii members with CKD using propensity score matching methods.

EFFECT OF THE BENCH SCALE EXTRACTION CONDITIONS ON Pinus radiata BARK EXTRACT YIELD, ANTIOXIDANT PROPERTIES AND COMPOSITION

REA Auditado

Many pine bark extracts have antioxidant properties. This work examined bench scale extraction on the yield, the composition and antioxidant properties of Pinus radiata. Acetone solvent (98.7% w/w at 120 °C) yielded maximum phenols concentration, tannins concentration, anti-radical activity (DPPH) and reducing activity (FRAP), although its extraction yield was the lowest. When the organic solvent in the mixture decreased, the chelating activity increased (ICA) and antiradical and reducing activities decreased.

Are there "black holes" in carbonate deposystems?

REA Auditado

The likelihood that extensive dissolution of aragonite (and high magnesian calcite) takes place during very early burial, even in relatively shallow tropical settings, has wide implications for interpreting and modelling ancient limestones. Some low energy environments may constitute net sinks (¿black holes¿) for carbonates. If this is the case attempts to model sediment budgets and develop depth-productivity profiles for carbonate systems require as yet unavailable quantitative data on the effects of these processes.

Implications of Higher Global Food Prices for Poverty in Low-Income Countries

REA Auditado

In many poor countries, the recent
increases in prices of staple foods raise the real incomes
of those selling food, many of whom are relatively poor,
while hurting net food consumers, many of whom are also
relatively poor. The impacts on poverty will certainly be
very diverse, but the average impact on poverty depends upon
the balance between these two effects, and can only be
determined by looking at real-world data.

HIV/AIDS, Climate Change and Disaster Management : Challenges for Institutions in Malawi

REA Auditado

Southern African institutions involved
in disaster management face two major new threats: the
HIV/AIDS pandemic (eroding organizational capacity and
increasing vulnerability of the population), and climate
change (higher risk of extreme events and disasters).
Analyzing the combined effects of these two threats on six
disaster-related institutions in Malawi, the authors find
evidence of a growing gap between demand for their services
and capacity to satisfy that demand.

An injury awareness education program on outcomes of juvenile justice offenders in Western Australia: an economic analysis

REA Auditado

Abstract
Background
Injury is a major cause of mortality and morbidity of young people and the cost-effectiveness of many injury prevention programs remains uncertain. This study aimed to analyze the costs and benefits of an injury awareness education program, the P.A.R.T.Y.

Evaluation in the Practice of Development

REA Auditado

Knowledge about development
effectiveness is constrained by two factors. First, the
project staff in governments and international agencies who
decide how much to invest in research on specific
interventions are often not well informed about the returns
to rigorous evaluation and (even when they are) cannot be
expected to take full account of the external benefits to
others from new knowledge. This leads to under-investment in
evaluative research.

Yield stress modelling of doped alumina suspensions for applications in freeze granulation: towards dry pressed transparent ceramics

REA Auditado

Rheology of powder suspensions is a key factor in many processing routes, and better understanding of the parameters that control the rheology improves technical progress by reducing the empirical factors in the formulation of powder slurries. The strict requirements for the production of transparent polycrystalline alumina demand a fundamental understanding of powder handling and processing steps. The use of dopants (Mg, Y, La) has proven useful, but produces noticeable effects on suspension rheology and influences the choice of the processing route.

The Impact of Remittances on Rural Poverty and Inequality in China

REA Auditado

Large numbers of agricultural labor
moved from the countryside to cities after the economic
reforms in China. Migration and remittances play an
important role in transforming the structure of rural
household income. This paper examines the impact of
rural-to-urban migration on rural poverty and inequality in
the case of Hubei province using the data of a 2002
household survey.
