Unconventional Optical Imaging for Biology
by Corinne Fournier Olivier HaeberléOptical imaging of biological systems has undergone spectacular development in recent years, producing a quantity and a quality of information that, just twenty years ago, could only be dreamed of by physicists, biologists and physicians. Unconventional imaging systems provide access to physical quantities – phase, absorption, optical index, the polarization property of a wave or the chemical composition of an object – not accessible to conventional measurement systems. To achieve this, these systems use special optical setups and specific digital image processing to reconstruct physical quantities. This field is also known as computational imaging. This book presents various non-conventional imaging modalities developed for the biomedical field: wave front analysis imaging, digital holography/tomography, optical nanoscopy, endoscopy and singlesensor imaging. Experimental setups and reconstruction algorithms are presented for each modality.

Urban Slums and Circular Economy Synergies in the Global South: Theoretical and Policy Imperatives for Sustainable Communities (Advances in 21st Century Human Settlements)
by Seth Asare Okyere Matthew Abunyewah Michael Odei Erdiaw-Kwasie Festival Godwin BoatengThis book takes a theoretical and empirical distance from urban slums/low-income settlements as a threat to environmental sustainability and recast them as places where environmentally rehabilitative and circular practices occur—drawing on the theoretical lens of the circular economy (CE). CE is defined as regenerative system that minimizes waste, emission, and energy leakage by slowing, closing, and narrowing material and energy loops. In principle, CE departs from the traditional linear model of take-make-use-dispose. As conceived in urban contexts, circular cities offer possibilities to regenerate natural systems, design out waste, and keep products in use. While the CE key principles of reduce, repair, and reuse are essential to the sustainable and inclusive interventions in urban slums, there is lack of case studies exploring the role of place and agency, especially the slum living-CE nexus in global south contexts. In inequitable urban transitions, a nuanced understanding of thesynergies between urban slums and the circular economy is not only theoretically relevant for reconceptualizing the slum in urban sustainability discourses but also exert policy and practice ramifications to decidedly figure out how the urban slum phenomenon can foster the sustainable and inclusive development of marginal areas through contextual and people-centered initiatives.

Using 137Cs Resampling Method to Estimate Mean Soil Erosion Rates for Selected Time Windows (Environmental Science and Engineering)
by Paolo Porto Emil Fulajtar Lee Kheng HengThis book provides guidelines for using a new approach of resampling the Cs-137 radionuclide tracer which is used to estimate soil erosion rates. The Cs-137 resampling approach will improve significantly the use of the Cs-137 method for assessment of soil erosion, because resampling the radionuclide repeatedly (at least two times, but more sampling campaigns are possible) allows to avoid several methodological difficulties associated with Cs-137 method, namely the problems with small-scale spatial heterogeneity, the question of representativeness of reference site, reference samples, and inappropriate time extent of evaluated period. All these methodological problems are very important for reliability and accuracy of erosion rates estimated by Cs-137 method. If using single sampling approach, the small-scale spatial heterogeneity can be overcome by high number of sampling points, but this is time and labour demanding solution increasing the expenses of the erosion research. The representativeness of reference site is evaluated usually on the basis of expert judgement and knowledge of land use history of studied area, but this approach is often uncertain because the expert judgement can be subjective and the data on land use history is often not sufficient. Further, in many areas an appropriate reference site is not available, what limits the territorial extent of using Cs-137 method. The resampling approach offers its second sampling to be done in a proximate vicinity of the same points sampled during the first sampling campaign. A great advantage is the possibility to decide how long time windows should be investigated. Choosing the time schedule of first and second sampling allows to shorten the time window and adjust it to the study objectives. This is a great improvement of the Cs-137 method, because the time period since the Cs-137 fallout is still growing and thus if using the single sampling approach the results refer to still longer and longer time window(since the Cs-137 fallout until the sampling time), and this period (recently ca 60 years assuming the maximum Cs-137 fallout in 1963) is too long to represent stable land use, because land uses are changing over the time and having the same land use over six decades is rather rare. The improvement of Cs-137 method achieved by resampling approach is significantly contributing to understanding the erosion dynamics and estimating its rates under changing environmental conditions (such as land uses, weather), and it will bring a significant benefit to soil conservation programmes, because Cs-137 method is indispensable for assessing the medium and long term soil erosion rates, and this information is among the basic inputs needed for planning and designing soil conservation measures.
