We present the formal derivation of a new unidirectional model for unsteady mixed flows in nonuniform closed water pipes. In the case of free surface incompressible flows, the FS-model is formally obtained, using formal asymptotic analysis, which is an extension to more classical shallow water models. In the same way, when the pipe is full, we propose the P-model, which describes the evolution of a compressible inviscid flow, close to gas dynamics equations in a nozzle. In order to cope with the transition between a free surface state and a pressured （i.e., compressible） state, we propose a mixed model, the PFS-model, taking into account changes of section and slope variation.

Over the centuries,the regeneration field has been puzzled by the dual response of the central nervous system(CNS-brain,spinal cord,cranial nervesⅠandⅡ)and the peripheral nervous system(PNS that refers to all the nerves that innervate muscles,skin,organs,bones among others).Even Ramon y Cajal had noticed that an injury to the PNS often leads to axon regrowth,in contrast to the CNS.

The generation of mice lacking SCYL1 or SCYL2 and the identification of Scyl1 as the causative gene in the motor neuron disease mouse model muscle deficient（Scyl1^（mdf/mdf）） demonstrated the importance of the SCY1-like family of protein pseudokinases in neuronal function and *** essential cellular processes such as intracellular trafficking and nuclear tRNA export are thought to be regulated by SCYL ***,whether deregulation of these processes contributes to the neurodegenerative processes associated with the loss of SCYL proteins is still ***,I briefly review the evidence supporting that SCYL proteins play a role in these processes and discuss their possible involvement in the neuronal functions of SCYL proteins.I also propose ways to determine the importance of these pathways for the functions of SCYL proteins in vivo.

Neurons of the mature central nervous system(CNS,mainly the brain and spinal cord)are unable to regenerate spontaneously after a lesion,in contrast to neurons of the peripheral nervous system(PNS).While the extraneuronal environment was long thought to be limiting,evidence was given less than 15 years ago that neurons themselves are critical players of their own regeneration(Park et al.,2008).Indeed,CNS neurons show a decline of axon growth capacity as they mature and after an ***,the role of axonal translation is actively explored in the paradigm of embryonic neuronal growth and in peripheral nerve injury and regeneration,but less is known about the role of local protein synthesis in regrowth of adult CNS *** we discuss how the current understanding of axonal translation in the CNS may contribute to the development of novel strategies to enhance axon regeneration in the injured CNS.

Near-infrared spectroscopy(NIRS)has been increasingly utilized in both sport and health sciences to assess various physiological parameters related to exercise performance.1 NIRS methods coupled with the recent development of portable and wearable devices suitable for field-based measurements have revolutionized the study of exercise physiology and the determinants of exercise performance by providing real-time,non-invasive,and spatially localized measurements of tissue oxygenation dynamics.

Changing behaviours and attitudes towards more sustainable individual energy consum- ption is a difficult topic to address. After identifying the most recurrent factors influencing bad energy consum- ption-society＇s environmental short- sightedness, a lack of individual responsibility and a tendency to put responsibility upon firms, institutions, and governments, the authors evaluated the effect business practices can have on individual behaviour. By qualifying as highly credible sources of information, positioning themselves as examples to follow and providing its employees with the necessary smart, innovative technology, business communities can have a major impact on changing individual behaviours towards more sustainable energy consumption.

The article aims to highlight the topicality of the old controversy between Werner Sornbart and Max Weber upon the origins of Western capitalism. Is its emergence explained by an universal passion for luxury and money or by the advent of new religious forms favorable toward saving and investment？ The article shows that what characterizes capitalism today is the extreme variety of the life forms, and therefore the fragmentation of the forms of personality, which can favor capitalism or be absorbed in it. This observation provides the means to evaluate, with a fresh look, the conclusions of one of the most famous and constitutive discussions in the history of modern European sociology.
