The real fluid, between the molecules of which intermolecular forces are acting is regarded as an ideal fluid without molecular interaction situated in an external force field. A force potential is assigned to this virtual force field, and it is shown that all the equilibrium properties of real fluids can be expressed in terms of this virtual potential or/and of its derivatives. Equations are given, expressing the common state functions of pure substances as functions of the virtual potential. In addition, it is shown that close relationships do exist between the approach mentioned above and the known fundamental approaches, such as the dynamical and statistical-mechanical one. Therefrom it is evident that the approach proposed here represents an additional alternative for the description of equilibrium properties of fluids which is equivalent to the existing approaches from the formal point of view.

Most of the common road accidents are due to the driver’s inappropriate behavior, lack of attention, tiredness, and road conditions which usually cause the vehicle to deviate from the roadway or crash into others. Although, thanks to the Steer-by-Wire system, recent research showed that is now possible to enhance vehicles’ manipulability and users’ safety by stimulating the drivers to react efficiently in common and critical situations. This paper describes a new strategy to assist the driver in his trajectories’ planning on a multiple-lane highway. A driving assistant is here designed to give appropriate and continuous tactile feedbacks generated from a virtual force field present in the roadway’s environment. First, the assistant algorithm global structure is presented. Then, a road condition dependant virtual force field based driving input is designed in order to avoid road deviations as well as to enhance safety in presence of potentially dangerous road conditions, as lack of adherence and visibility. The performance of the system is evaluated firstly through preliminary simulations, and then confirmed on a driving simulator.

This chapter explores the funerary rites in the Phoenician-Punic world from a comprehensive point of view, and it focuses on the common points arising from a large amount of data. The concern for burying their deceased and the belief in the soul’s afterlife show that the Phoenicians considered death as a transformation rather than as the end of a person’s life. Through our access to archaeological remains and written sources, we can reconstruct the existence of a meaningful burial program that was destined to provide a “good death” and afterlife. Funerary rituals, thus, are the actions or gestures to achieve this goal. The aim of this chapter is to explain the rites that family members undertook once someone died, in order to transform correctly the deceased person into an otherworldly being, the ancestor. The social implications of the data arising from burials are also briefly considered.

A joint and unified vision of stochastic diffusion models associated with the family of hyperbolastic curves is presented. The motivation behind this approach stems from the fact that all hyperbolastic curves verify a linear differential equation of the Malthusian type. By virtue of this, and by adding a multiplicative noise to said ordinary differential equation, a diffusion process may be associated with each curve whose mean function is said curve. The inference in the resulting processes is presented jointly, as well as the strategies developed to obtain the initial solutions necessary for the numerical resolution of the system of equations resulting from the application of the maximum likelihood method. The common perspective presented is especially useful for the implementation of the necessary procedures for fitting the models to real data. Some examples based on simulated data support the suitability of the development described in the present paper.

The knowledge of the topological structure and the automatic fare collection systems in urban public transport produce many data that need to be adequately analyzed, processed and presented. These data provide a powerful tool to improve the quality of transport services and plan ahead. This paper aims at studying, from a mathematical and statistical point of view, the Barcelona metro network; specifically: (1) the structural and robustness characteristics of the transportation network are computed and analyzed considering the complex network analysis; and (2) the common characteristics of the different subway stations of Barcelona, based on the passenger hourly entries, are identified through hierarchical clustering analysis. These results will be of great help in planning and restructuring transport to cope with the new social conditions, after the pandemic.

Heart failure has been defined in many ways and definitions change over time. The multiplicity of definitions reflect the paucity of our understanding of the primary underlying physiology of heart failure and the many diseases for which heart failure is the common end-point. Fundamentally, heart failure represents a failure of the heart to meet the body’s requirement for blood supply for whatever reason. It is thus a clinical syndrome with characteristic features – not a single disease in its own right. The syndrome includes symptoms and signs of organ underperfusion, fluid retention and neuroendocrine activation. The syndrome arises from a range of possible causes of which ischaemic heart disease is the commonest. From the point of view of a clinician, the underlying pathology will determine treatment options and prognosis. The extensive range of possible aetiologies present a diagnostic challenge both to correctly identify the syndrome amongst all other causes of dyspnoea and to identify the aetiology, allowing optimization of treatment.

Summary The objective of the paper is to present the results of negotiations on the EU budget for 2014-2020, with particular emphasis on the Common Agricultural Policy. Authors indicate the steps for establishing the budget, from the proposal of the European Commission presented in 2011, ending with the draft of UE budget agreed at the meeting of the European Council on February 2013 and the meeting of the AGRIFISH on March 2013 and then approved by the political agreement of the European Commission, European Parliament and European Council on June 2013. In this context, there will be an assessment of the new budget from the point of view of Polish economy and agriculture.

This paper is a response to Dale Hutchison’s recent arguments about the role of fairness in contract law after the Constitution. From the point of view of transformative constitutionalism, the paper argues that the fairness ‘debate’ in the South African law of contract should be approached as what it so patently is, namely, as evidence of a deep ideological conflict that has existed in our law of contract for a very long time, and that this debate now exists within the context of a larger debate about the appropriate transformative reach of the Constitution. The argument takes the form of two ‘dangerous supplements’ to Hutchison’s discourse. The first of these supplements contends that indeterminacy is a symptom of the common law itself, rather than a result of contract law’s contact with the Constitution. The second dangerous supplement suggests a responsible judicial engagement with bona fides and ubuntu, one that can exploit the strengths of both the common law and the Constitution and that understands good faith and ubuntu to be ‘inter-linking’ constitutional values that should be enlisted in unison or at least in resonance when it comes to the question of fairness in our contemporary law of contract. In conclusion, I offer a reading of Hutchison’s own politics of contract law and contend that his is an altruistic politics committed to the standard form. I contend that this politics of contract law is consistent with a transformative understanding of the post-apartheid legal order. ‘Law, like every other cultural institution, is a place where we tell one another stories about our relationships with ourselves, one another, and authority. In this, law is no different from the Boston Globe, the CBS evening news, Mother Jones, or a law school faculty meeting. When we tell one another stories, we use languages and themes that different pieces of the culture make available to us, and that limit the stories we can tell. Since our stories influence how we imagine, as well as how we describe, our relationships, our stories also limit who we can be’.
