A Self Reconfigurable Undulating Grasper for Asteroid Mining
A SELF RECONFIGURABLE UNDULATING GRASPER FOR ASTEROID MINING Suzanna Lucarotti1, Chakravarthini M Saaj1, Elie Allouis2 and Paolo Bianco3 1Surrey Space Centre, Guildford UK 2Airbus DS, Stevenage UK 3Airbus, Portsmouth UK ABSTRACT are estimated as over 1km diameter and 4133 as 300- 1000m diameter. While surface features remain mostly unknown, mass and orbit parameters are available. The Recent missions to asteroids have shown that many have closest NEAs can be reached with less ∆V than the rubble surfaces, which current extra-terrestrial mining Moon. techniques are unsuited for. This paper discusses mod- elling work for autonomous mining on small solar system There have been so far been five missions to the sur- bodies, such as Asteroids.

INCLUSIVE EDUCATION AND SCHOOL REFORM IN POSTCOLONIAL INDIA Mousumi Mukherjee MA, MPhil, Calcutta University; MA Loyola University Chicago; EdM University of Illinois, Urbana-Champaign Submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy Education Policy and Leadership Melbourne Graduate School of Education University of Melbourne [5 June 2015] Keywords Inclusive Education, Equity, Democratic School Reform, Girls’ Education, Missionary Education, Postcolonial theory, Globalization, Development Inclusive Education and School Reform in Postcolonial India i Abstract Over the past two decades, a converging discourse has emerged around the world concerning the importance of socially inclusive education. In India, the idea of inclusive education is not new, and is consistent with the key principles underpinning the Indian constitution. It has been promoted by a number of educational thinkers of modern India such as Vivekananda, Aurobindo, Gandhi, Ambedkar, Azad and Tagore. However, the idea of inclusive education has been unevenly and inadequately implemented in Indian schools, which have remained largely socially segregated. There are of course major exceptions, with some schools valiantly seeking to realize social inclusion. One such school is in Kolkata, which has been nationally and globally celebrated as an example of best practice. The main aim of this thesis is to examine the initiative of inclusive educational reform that this school represents. It analyses the school’s understanding of inclusive education; provides an account of how the school promoted its achievements, not only within its own community but also around the world; and critically assesses the extent to which the initiatives are sustainable in the long term. -
Concepts & Synthesis
CONCEPTS & SYNTHESIS EMPHASIZING NEW IDEAS TO STIMULATE RESEARCH IN ECOLOGY Ecological Monographs, 81(3), 2011, pp. 349–405 Ó 2011 by the Ecological Society of America Regulation of animal size by eNPP, Bergmann’s rule, and related phenomena 1,3 2 MICHAEL A. HUSTON AND STEVE WOLVERTON 1Department of Biology, Texas State University, San Marcos, Texas 78666 USA 2University of North Texas, Department of Geography, Denton, Texas 76203-5017 USA Abstract. Bergmann’s rule, which proposes a heat-balance explanation for the observed latitudinal gradient of increasing animal body size with increasing latitude, has dominated the study of geographic patterns in animal size since it was first proposed in 1847. Several critical reviews have determined that as many as half of the species examined do not fit the predictions of Bergmann’s rule. We have proposed an alternative hypothesis for geographic variation in body size based on food availability, as regulated by the net primary production (NPP) of plants, specifically NPP during the growing season, or eNPP (ecologically and evolutionarily relevant NPP). Our hypothesis, ‘‘the eNPP rule,’’ is independent of latitude and predicts both spatial and temporal variation in body size, as well as in total population biomass, population growth rates, individual health, and life history traits of animals, including humans, wherever eNPP varies across appropriate scales of space or time. In the context of a revised interpretation of the global patterns of NPP and eNPP, we predict contrasting latitudinal correlations with body size in three distinct latitudinal zones. The eNPP rule explains body- size patterns that are consistent with Bergmann’s rule, as well as two distinct types of contradictions of Bergmann’s rule: the lack of latitudinal patterns within the tropics, and the decline in body size above approximately 608 latitude. -

The descent probe is a carry-on small spacecraft (< 100 kg), to be deployed by the mother spacecraft, that brings itself onto a collisional trajectory with the targeted planetary body in a simple manner. A possible science payload includes instruments for surface imaging, characterisation of the neutral exosphere, and magnetic field and plasma measurement near the target body down to very low-altitudes (~1 km), during the probe’s fast (~km/s) descent to the surface until impact. The science goals and the concept of operation are discussed with particular reference to Europa, including options for flying through water plumes and after-impact retrieval of very-low altitude science data. -

Chicago Wilderness Region Urban Forest Vulnerability Assessment
United States Department of Agriculture CHICAGO WILDERNESS REGION URBAN FOREST VULNERABILITY ASSESSMENT AND SYNTHESIS: A Report from the Urban Forestry Climate Change Response Framework Chicago Wilderness Pilot Project Forest Service Northern Research Station General Technical Report NRS-168 April 2017 ABSTRACT The urban forest of the Chicago Wilderness region, a 7-million-acre area covering portions of Illinois, Indiana, Michigan, and Wisconsin, will face direct and indirect impacts from a changing climate over the 21st century. This assessment evaluates the vulnerability of urban trees and natural and developed landscapes within the Chicago Wilderness region to a range of future climates. We synthesized and summarized information on the contemporary landscape, provided information on past climate trends, and illustrated a range of projected future climates. We used this information to inform models of habitat suitability for trees native to the area. Projected shifts in plant hardiness and heat zones were used to understand how nonnative species and cultivars may tolerate future conditions. We also assessed the adaptability of planted and naturally occurring trees to stressors that may not be accounted for in habitat suitability models such as drought, flooding, wind damage, and air pollution. The summary of the contemporary landscape identifies major stressors currently threatening the urban forest of the Chicago Wilderness region. Major current threats to the region’s urban forest include invasive species, pests and disease, land-use change, development, and fragmentation. Observed trends in climate over the historical record from 1901 through 2011 show a temperature increase of 1 °F in the Chicago Wilderness region. Precipitation increased as well, especially during the summer. -

Introduction: The new era of sample return missions had started since the Stardust returned samples from com- et 81P/Wild 2 in 2006 [1], followed by the Hayabusa spacecraft from the near-Earth S-type asteroid 25143 Itokawa in 2010 [2,3]. In this year, Hayabusa2 will reach its target body, the near-Earth C-type asteroid 162173 Ryugu [4], and also OSIRIS-REx toward the near-Earth B-type asteroid 101955 Bennu [5]. Additionally, several other sample return missions have been planned recently, such as the Martian Moons eXplorer (MMX) for the Phobos and/or Deimos [6], the CAESAR for 67P/Churyumov-Gerasimenko [7], and the HELACLES for the the Moon [8]. -
