Every human society has a history that it takes pride in. In times of despair there could be invocation or calls to return to that history either as an informant of correct practice or as an inspiration of what current practice should be. Hence some African scholars and politicians have made calls that seek to return to that source. At least three problems pose some significant threat to the project of the return to the source. Firstly, there is a problem of interpreting what the exact nature of that traditional set up was, secondly there is a problem of working out how the traditional mode can fit into the modern, and thirdly there is the problem of the possibility that different sources existed in that pristine past. Without an adequate response to these threats, the return may not be as smooth as its advocates have thought it to be.

The current paper presents an experimental study of the energy budget of a two-dimensional internal wave attractor in a trapezoidal domain filled with uniformly stratified fluid. The injected energy flux and the dissipation rate are simultaneously measured from a two-dimensional, two-component, experimental velocity field. The pressure perturbation field needed to quantify the injected energy is determined from the linear inviscid theory. The dissipation rate in the bulk of the domain is directly computed from the measurements, while the energy sink occurring in the boundary layers is estimated using the theoretical expression for the velocity field in the boundary layers, derived recently by Beckebanze et al. (J. Fluid Mech., vol. 841, 2018, pp. 614–635). In the linear regime, we show that the energy budget is closed, in the steady state and also in the transient regime, by taking into account the bulk dissipation and, more importantly, the dissipation in the boundary layers, without any adjustable parameters. The dependence of the different sources on the thickness of the experimental set-up is also discussed. In the nonlinear regime, the analysis is extended by estimating the dissipation due to the secondary waves generated by triadic resonant instabilities, showing the importance of the energy transfer from large scales to small scales. The method tested here on internal wave attractors can be generalized straightforwardly to any quasi-two-dimensional stratified flow.

In a normal port operation, yard cranes are used to move containers from one location to another for import, export or relocation purposes. In order to locate the positions of containers, a database is set up in the office server to store the current locations of existing containers within the yard. Whenever the Rubber Tyred Gantry (RTG) crane operator moves a container around, the database has to be updated via a program installed in the Vehicle Mounted Terminal (VMT) fitted to the crane. This requires the establishment of a communication channel between the server and the crane VMT. The current practice is to make use of wireless networks, even though these are susceptible to attenuation and interferences in rugged surroundings as in a port. This paper describes and explores another alternative, that of using 2G/SMS for short messages and 3G networks for real-time scenarios. These methods are more reliable as major telecommunication service providers normally expend substantial resources in infrastructure development. They also provide a cheaper alternative in terms of reducing maintenance expenses.

AbstractIn this article, we lay out the basic case for wellbeing as the goal of government. We briefly review the history of this idea, which goes back to the ancient Greeks and was the acknowledged ideal of the Enlightenment. We then discuss possible measures on which a wellbeing orientation could be based, emphasizing the importance of acknowledging the political agency of citizens and thus their own evaluations of their lives. We then turn to practicalities and consequences: how would one actually set up wellbeing-oriented decision-making and what difference should we expect from current practice? We end by discussing the current barriers to the adoption of wellbeing as the goal of government, both in terms of what we need to know more about and where the ideological barriers lie.

The earthquake was a double-edged sword. On one hand, it brought about catastrophe to the human society. On the other hand, it created plentiful preciously earthquake ruins resources. Based on previous studies on earthquake sites resources, it aimed to explore methods and measurements of protecting earthquake ruins resources from the heritage protection perspective. Firstly, the notion of earthquake site was defined, then the classification system of earthquake ruins was set up and the earthquake ruins in Sichuan province were listed. Secondly, the values of Sichuan earthquake ruins were analyzed, such as scientific value, spiritual culture value, science education value and tourist economy value. Finally, those earthquake sites must be kept in authenticity and integrity. This paper also illustrated the process of protecting the earthquake sites in Sichuan. The objective of this study was to preserve the earthquake ruins resources well and provide experiences for protecting the similar ruins or sites resources.

The article provides material on the organization and characteristics of equestrian tourism. The popularity of equestrian tourism is now growing rapidly throughout the world. Everywhere, campsites are built to service riders, horse-riding routes are laid. Equestrian tourism squeezes into the background many traditional types of travel. Considering the huge interest shown to equestrian tourism by various strata of the population in many countries of the world, the International Equestrian Federation has paid serious attention to this issue in recent years. Within the framework of the Federation, a special commission has been set up under the supervision of the Italian professor Vittorio de Sanctis, who has begun working out rules for conducting international horse-riding tours, hikes and runs. Horse tourism is an integral part of eco-tourism. For the organization of equestrian tourism, a proper base is needed, horses are properly trained for horse riding and saddlery, a school of instructors and methods for training tourists to care for horses and handling them, arranging training for hikers, working out routes with halts, and preparing feed for horses. Equestrian tourism in Ukraine is developing, winning more and more supporters. This type of active tourism enjoys well-deserved popularity among horseback riding enthusiasts of natural, ethnic, historical, extreme, pilgrimage, hunting, fishing, and mountain destinations. Equestrian tourism is an attractive way of spending time and studying from inside the life of the inhabitants of the country. Any rest on horses is interesting and fascinating, and everyone can take with them a positive impression. In addition, the horse is a unique live simulator. It is thanks to this ability that a method of medical riding, or hippotherapy, has emerged, which has become one of the effective ways to rehabilitate the disabled.

Microstructure Imaging

Some collectors and connoisseurs have found that the nephrite from different sources possess different sub-microstructures inside the body, which could become a quite convenient and effective basis for determining provenance. The sub-microstructure of nephrite can be observed by the naked eye under irradiated by strong light. However, the images of original submicrostructure of nephrite were recorded by use of multispectral imaging in our previous work, but the visual effect is not satisfied. Here, the main features of different sub-microstructures will present more distinct by appropriately subtracting the shining strength and then the average filtering is adopted to promote the resolution of sub-microstructure imaging as well as to reduce some image noises. The sub-microstructure images of nephrite from five most common sources have typical inherent characteristics respectively, which are qualified to set up a demonstration for identifying provenances. Furthermore, the shape, size, distribution and name for these different sub-microstructures have been summarized and they will become the basis for future research on the provenance of nephrite including the ancient jade.

The Way

The early phases of pattern formation, as described in the two previous chapters, set the stage for all that follows—for the whole grand sweep of morphogenesis by which the phenotype is created. Right from the oocyte stage there is an ordering of the embryo, both in the sense of spatial patterning and in the sense of setting in place the components of developmental processes. As pattern formation continues, particularly in “regulative” embryos, the ordering of the embryo becomes more and more specific. A point is reached that is quite impossible to define but nonetheless real, when the embryo is set up in such a way that all the components are in place. At least, everything has been specified. Such an embryo, for example the amphibian neurula, may look very little like the final phenotype, but from this point onward morphogenesis represents a working out of potentials that have already been established. All the basic morphogenetic information is in place. Morphogenesis is both simple and complex. It is simple because relatively few processes will be involved. It is complex because of the diversity of cell and tissue types that is involved, because of the subtlety of control of differentiation and even size and shape in organogenesis, and because of the complexity of both embryonic and subsequent adult function. Finally, it is complex because of the interactivity and “wholeness” of the developing embryo as well as the multiplicity of the parts making up that whole. It is with the simplicity of morphogenetic processes, the relatively small number of cell and tissue-level processes involved (processes that are common to all morphogenetic systems), that we will be concerned first. In order to understand both the basic rules of development and the way in which they relate to mechanisms for the introduction of evolutionarily significant phenotypic variation (Chapter 2), we must understand first these common processes of morphogenesis, and the way in which they operate under the rules and mechanisms of pattern control discussed in the previous chapters. Morphogenesis involves a relatively small number of phenomena characteristic of all cells and tissues, and their relation to features of the extracellular environment.

Inclusions removal by flotation in mechanically agitated vessels is widely used in liquid aluminium treatments. Originating from different sources (oxide skins, refractory or recycling wastes), inclusions may have disastrous repercussions, such as physical properties alterations of the final products or difficulties during forging processes.With the aim of both a better understanding of the physical processes acting during flotation and the optimization of the refining process, a mathematical modelling of the behaviour of the inclusions population has been set up. Agglomeration, flotation and settling of inclusions are considered here. The model is divided in two steps: a 3D calculation of the biphasic liquid aluminium/bubbles fluid flow based on an Euler/Lagrange approach and a population balance. The population balance is performed with the assumption of a perfectly stirred reactor, and the calculation of agglomeration and flotation rates relies on mean values of fluid flow properties provided by the CFD simulation. Kruis & Kusters' model is employed for the calculation of the agglomeration rate and Kostoglou's model is used for the flotation rate. The fixed pivot method of Kumar & Ramkrishna is employed for the resolution of the population balance equation.A laboratory scaled flotation vessel is modeled and results of a simulation are presented.

Bad News Delivery

As a result of the COVID-19 global pandemic, paramedics in the UK face unprecedented challenges in the care of acutely unwell patients and their family members. This article will describe and discuss a new ethical dilemma faced by clinicians in the out-of-hospital environment during this time, namely the delivery of bad news to family members who are required to remain at home and self-isolate while the critically unwell patient is transported to hospital. I will discuss some failings of current practice and reflect on some of the ethical and practical challenges confronting paramedics in these circumstances. I conclude by making three recommendations: first, that dedicated pastoral outreach teams ought to be set up during pandemics to assist family members of patients transported to hospital; second, I offer a framework for how bad news can be delivered during a lockdown in a less damaging way; and finally, that a new model of bad news delivery more suited for unplanned, time-pressured care should be developed.
