According to many previous studies,application of remote sensing for the complex and heterogeneous urban environments in Sub-Saharan African countries is challenging due to the spectral confusion among features caused by diversity of construction *** to classification based on spectral indices that are expected to better highlight features of interest and to be prone to unsupervised classification,this study aims(1)to evaluate the effectiveness of index-based classification for Land Use Land Cover(LULC)using an unsupervised machine learning algorithm Product Quantized K-means(PQk-means);and(2)to monitor the urban expansion of Luanda,the capital city of Angola in a Logistic Regression Model(LRM).Comparison with state-of-the-art algorithms shows that unsupervised classification by means of spectral indices is effective for the study area and can be used for further *** built-up area of Luanda has increased from 94.5 km2 in 2000 to 198.3 km2 in 2008 and to 468.4 km2 in 2018,mainly driven by the proximity to the already established residential areas and to the main roads as confirmed by the logistic regression *** generated probability maps show high probability of urban growth in the areas where government had defined housing programs.

Whilst caking occurs via several different mechanisms,absorption and migration of moisture is frequently the most dominant mechanism within the food and pharmaceutical *** understanding the propensity to cake is important for minimising down-stream process issues,however most characterisation techniques assume that moisture induced caking occurs homogenously through the sample resulting in a uniformly caked powder *** this study,the effect of moisture induced caking on powder flowability was investigated using powder *** materials,including skimmed milk powder(SMP)and sulphated methyl ester(SME)were stored for several days under controlled humidity *** flow energies,a measure of the resistance to flow,were measured at 24 h intervals using an FT4 Powder *** the energy is measured as a function of the bed height,variations in the powder bed are also *** results demonstrated that caking does not always occur uniformly,instead a caked region(or crust)forms at the air-powder interface and then progresses through the powder ***,the strength of this caked region was shown to increase over several days before stabilising.

本文首次确认Nathan Lewis及其合作者于1989年5月1日在美国马里兰州巴尔的摩举行的美国物理学会(APS)会议上所犯的关键计算错误。Lewis等人分析了Martin Fleischmann及其合作者报告的9轮实验中的热测量结果,并报告在没有催化复合的情况下每轮实验都显示出异常的热功率损失。而本文使用相同的原始数据,经过正确的计算,再次确认每轮实验都显示出异常的功率增益。因此,这些数据意味着可能存在一种能产生能量的新物理现象。

Plant Diversity 2019年第2期41卷 124-131页

作者： Ted Chapman Stephanie miles Clare Trivedi Royal Botanic Gardens Kew

Ex situ seed banking is a practical and cost-effective means of preserving wild plant diversity and a crucial complement to the in situ conservation and restoration of species and habitats. As pressures on the natural environment have grown, so has the call for seed banks to provide scientifically-robust,practical solutions to seed-related problems in nature conservation, from single-species recovery and reintroduction to the restoration of complex, dynamic communities at the largest scales. In this paper, we discuss how the Royal Botanic Gardens, Kew and its Millennium Seed Bank have responded to this call in the United Kingdom. We demonstrate that banked seed collections can provide a range of otherwiseunavailable, high quality, known-origin, genetically-diverse biological materials. The data, expertise and specialist facilities that accompany these collections are also valuable, helping overcome constraints to the collection, production and effective use of native seed. Challenges remain-to ensure ex situ collections protect the species and genetic diversity that will enable plants to adapt to a changing environment, and to find new ways for seed banks to mobilise their resources at a landscape scale.
