On Classification of Finite-Dimensional Superbialgebras and Hopf Superalgebras

The purpose of this paper is to investigate finite-dimensional superbialgebras and Hopf superalgebras. We study connected superbialgebras and provide a classification of non-trivial superbialgebras and Hopf superalgebras in dimension $n$ with $n\leq 4$

Capacitary type estimates in strongly nonlinear potential theory and applications

In this article a general result on smooth truncation of Riesz and Bessel potentials in Orlicz-Sobolev spaces is given and a capacitary type estimate is presented. We construct also a space of uasicontinuous functions and an alternative characterization of this space and a description of its dual are established. For the Riesz kernel Rm, we prove that operators of strong type (A, A), are also of capacitaries strong and weak types (m, A)

Prevalence and factors favoring overweight and obesity in Algerian child and adolescent; case of the population of Constantine / Algeria

AbstractBackground: Our objectives through this paper are multiple: to measure the prevalence of overweight and obesity in children between 5-11 years and in adolescents between 12-17 years; highlight the main causes that influence this phenomenon in children and adolescents under 18 years old; highlight the risk factors associated with overweight and obesity in these age groups; and finally, the policies to be applied to stop or curb this phenomenon.Methods: This is a descriptive, transversal survey which focused on a representative sample of children and adolescents during the month of July 2018. The study population consisted of 1022 children and adolescents aged 5 to 17 years, who frequent a municipal swimming pool located in the wilaya of Constantine / Algeria. These children and adolescents were selected by chance for a few days over the four weeks of July 2018. Information concerning the socio-demographic characteristics, eating habits and sedentary behavior for each individual was specified by means of a questionnaire. Results: Among the results of this study: overweight affects 14% of children between 5-11 years old, while with moderate obesity, it affects 4% of children in this age category; for adolescents aged 12-17 years, 17% of them are overweight, and 7% have moderate obesity; several factors contribute to gaining extra pounds (gender and age, some hereditary factors, eating habits and physical inactivity).Conclusion: Identifying the risk factors for overweight and obesity in children and adolescents under 18 years old, would help identify risky habits and behaviors in order to propose appropriate prevention measures. These measures should be included in a health education strategy and a health promotion strategy

The economic approach of road safety; unique objective and contradictory motivations!

Abstract: Although the topic is a multidisciplinary field, we will address, through this article, road safety from an angle, more or less economic. Thus, the scarcity of the human or material resources of the victims of the accident, the non-abundance of budgetary means allocated to mitigate the damage of the accident (hospital expenses, reimbursements of insurance companies, etc.), the efficiency of the choices to be learned by the public authorities to deal with the hecatomb and the socio-economic benefits of road users (individuals or companies), etc. are road safety issues that constitute, from near or far, a discipline that we can call "the economics of road safety".Through our analysis we arrived at these results: Although the objective of road safety is clear: "to save as much life as possible from the traffic hecatomb", the motivations of each stakeholder in a road safety are not homogeneous and can be even contradictory, that it is within the same group of actors or at the level of the society as a whole. Thus, the sources of this contradiction can be: cultural, social, economic, etc. which divides instead of gathering opinion of the different actors on questions like: the causes of the accident, the settlement of the prejudices of the insecurity road, the regulation which frames the road organization, the solutions to elaborate, of time to another, to improve the lives of road users. Finally, the rationality of our days is approached in an artificial way, restricted and limited by a cost-benefit approach peculiar to a modern, liberal and immoral society

The Amarna Diplomacy in IR Perspective : A System of States in the Making

The Amarna diplomacy (ca. 1365–1330 BCE) has been of interest for specialists ever since the discovery of the Amarna letter collection in the late 19th century. While it can be considered as one of the great archaeolo-gical discoveries of all time, it has largely remained out of academic purview in the field of International Relations (IR). IR scholarship continues to turn to the Greco-Roman experience in its attempt to delineate the chronological framework of the discipline. Far from being an anecdote in international history, this article aims to analyze what the letters convey for a student of world politics. What comes out of these missives through textual analysis of the primary sources is not only the various demands, wishes and security concerns of the actors involved but also classical IR themes such as power balancing, security dilemma and interna-tional anarchy. While there are question marks and lacunas, this paper asserts that the ancient Near Eastern world constituted an international arena where we see the makings of a genuine system of states more than a millennium before the writings of Thucydides. The Amarna letters, although incomplete, are a gateway to gain deeper synergy between IR theory and international history.Peer reviewe
