Recent advances in design, sensing and control have led to aerial robots that offer great promise in a range of real-world applications. However, one critical open question centres on how to improve the energetic efficiency of aerial robots so that they can be useful in practical situations. This review paper provides a survey on small-scale aerial robots (i.e. less than 1 m 2 area foot print, and less than 3 kg weight) from the point of view of energetics. The paper discusses methods to improve the efficiency of aerial vehicles, and reports on recent findings by the authors and other groups on modelling the impact of aerodynamics for the purpose of building energy-aware motion planners and controllers.

AbstractThe central question of this article — why people may change their religious affiliation or become disaffiliated — is relevant from both an academic and a practical point of view. The article makes first an inventory of existing literature on religious conversion. Next I sketch the contours of the new conversion careers approach I am currently working on. I make some comparisons with a region that is not usually mentioned in the literature on conversion: Latin America. These comparisons are based on my earlier fieldwork on Roman Catholicism, Pentecostalism, and Mormonism in Costa Rica and Guatemala (H. Gooren, Rich among the Poor: Church, Firm, and Household among Small-scale Entrepreneurs in Guatemala City, Amsterdam: Thela Thesis 1999).

This chapter examines the flow of goods across and through Crimea in an attempt to understand the impact of Russian rule on the economic landscape. It focuses on the patterns of exchange and consumption, arguing for the significance of small-scale transactions for understanding the economic geography of the region. While Russian officials were eager to facilitate and control Black Sea trade, farmers and gardeners and craftsmen began participating in the system of overland markets and fairs that connected the southern provinces to merchants and consumers everywhere from Kharkov and Moscow to Nizhnii Novgorod and Kazan. The Crimean economy thus moved southward toward Constantinople and northward toward Moscow, yet the towns of the peninsula remained key nodes of consumption and production, the orchards and vineyards key sites of prosperity.

Background: Supportive supervision of infection prevention and control (IPC) practices was one of a range of interventions employed at the county level in the control of the world’s most deadly Ebola virus disease outbreak that affected Liberia during 2013–2016. Methods: Datasets generated from four consecutive assessment visits to 25 health facilities in Maryland County, in Liberia, were analysed. Information on IPC practices was obtained by interview, direct observation and completion of a standardised assessment tool. For each of the IPC fields assessed, a score < 50% was graded poor, 50–75% as fair, while > 75% was rated as good. Results: Before the intervention, the first assessment (baseline) indicated that the majority of the health facilities scored low in terms of isolation facilities, IPC administration, supply and equipment, personnel and staffing, triage and waste management. Following the application of supportive supervision and monitoring, all the facilities recorded moderate to good performance in all the fields during the fourth round of assessment, except for isolation facilities, which scored low. Conclusion: Supportive supervision and monitoring of healthcare facilities appeared to have contributed to the improvement in IPC standards and compliance during the Ebola outbreak as demonstrated in this small-scale study and should be sustained as a core component of IPC programs, particularly in prolonged outbreak situations.

There are all sort of indications that Internet usage will go only upwards, resulting in an increase in energy consumption and CO2 emissions. At the same time, a significant amount of this carbon footprint corresponds to the information and communication technologies (ICT) sector, with around one third being due to networking. In this paper we have approached the problem of green networking from the point of view of sustainability. Here, alongside energy-aware routing, we have also introduced pollution-aware routing with environmental metrics like carbon emission factor and non-renewable energy usage percentage. We have proposed an algorithm based on these three candidate-metrics. Our algorithm provides optimum data and control planes for three different metrics which regulate the usage of different routers and adapt the bandwidth of the links while giving the traffic demand requirements utmost priority. We have made a comparison between these three metrics in order to show their impact on greening routing. The results show that for a particular scenario, our pollution-aware routing algorithm can reduce 36% and 20% of CO2 emissions compared to shortest path first and energy-based solutions, respectively.

AbstractThe scientific community has widely discussed the role of abiotic and biotic forces in reshaping the Earth’s surface. Currently, the literature is debating whether humans are leaving a topographic signature on the landscape. Apart from the influence of humans on processes, does the resulting landscape bear an unmistakable signature of anthropogenic activities? This research analyses from a statistical point of view the morphological signature of anthropogenic and natural land covers in different topographic context, as a fundamental challenge in the emerging debate of human-environment relationships and the modelling of global environmental change. It aims to explore how intrinsically small-scale processes, related to land use, can influence the form of entire landscapes and to determine whether these processes create a distinctive topography. The work focusses on four study areas in floodplains, plain to hilly, hills and mountains, for which LiDAR-derived Digital Terrain Models (DTMs) are available. Surface morphology is described with different geomorphometric parameters (slope, mean curvature and surface peak curvature) and their frequency distribution. The results show that the distribution of geomorphometric indices can reveal anthropogenic land covers and landscapes. In most cases, different land covers show statistically significant differences (p < 0.05) in their morphology. Finally, this study demonstrates the possibility to use a geomorphic analysis to quantify anthropogenic impact based on land covers in different landscape contexts. This provides useful insight into understanding the impact of human activities on the present morphology and offers a comprehensive understanding of coupling human-land interaction from a geomorphological point of view.

- Scientific literature provides substantial evidence on how socioeconomic circumstances influence health, showing that this association holds with any indicator of socioeconomic position, independently of the theoretical approach on which is based. The open question on the indicators used to represent socioeconomic position is: are they equal proxy of a third variable, social classification or stratification, or do they capture specific dimensions of this stratification, the impact of which would be measurable independently of the others? This paper gives a tentative answer, from the epidemiological point of view, examining the indicators of socioeconomic position most used in health research (education, employment status, occupational class, income and goods), particularly focusing on their meaning, i.e. what they intend to measure, together with how data are elicited and the validity and limitations of the indicators. Keywords: indicators, education, social class, income, sources, epidemiology, social determinants of health. Parole chiave: indicatori, istruzione, classe sociale, reddito, fonti, epidemiologia, determinanti sociali di salute.

This study aimed to examine the patterns of Jordanian undergraduates' youths exposure to the dubbed Turkish series, and to determine the motives and gratifications achieved by such series from their viewpoint, as well as to know the impact of these series and the values ​​it carries within on youth, by conducting a survey study using the questionnaire tool on a single stratified sample of (480) undergraduate Jordanian students. The study found that (48.3%) of the respondents watched the dubbed Turkish series for several reasons, most notably; achieving fun and entertainment and escaping from the pressures of their studies, most of the respondents believe that most values ​​included in the dubbed Turkish series contain threatening values ​​for morals and behavior, nonetheless, they provide an atmosphere of entertainment during their leisure time, and the most values ​​included in the dubbed Turkish series from the respondents' point of view stated as they: "containing values ​​threatening to morals and behavior", and they "add an atmosphere of entertainment during my free time", while the most achieved gratifications achieved while watching these series are acquiring knowledge of the Turkish society, and for fun and entertainment inquiry. Among the most important recommendations recommended by the study, the need for intellectual supervision and control over the dubbed Turkish series, as they contain ideas that contradict our Arab and Islamic reality, for viewers in general and for young people in particular, and the need to commit drama presented through Arab screens to display everything that works to protect identity, privacy and values Cultural through highlighting the richness of Arab society with important customs and traditions.
