This paper presents an original theoretical framework to model steel material properties in continuous casting line process. Specific properties arising from non-Newtonian dynamics are herein used to indicate the natural convergence of distributed parameter systems to fractional order transfer function models. Data driven identification from a real continuous casting line is used to identify model of the electromagnetic actuator device to control flow velocity of liquid steel. To ensure product specifications, a fractional order control is designed and validated on the system. A projection of the closed loop performance onto the quality assessment at end production line is also given in this paper.

Transient elastography and the acoustic radiation force impulse techniques may play a pivotal role in the study of liver fibrosis. Some studies have shown that elastography can detect both the progression and regression of fibrosis. Similarly, research results have been analysed and direct and indirect serum markers of hepatic fibrosis have shown high diagnostic accuracy for advanced fibrosis/cirrhosis. The prognosis of different stages of cirrhosis is well established and various staging systems have been proposed, largely based on clinical data. However, it is still unknown if either noninvasive markers of liver fibrosis or elastography may contribute to a more accurate staging of liver cirrhosis, in terms of prognosis and fibrosis regression after effective therapy. In fact, not enough studies have shown both the fibrosis regression in different cirrhosis stages and the point beyond which the prognosis does not change- even in the event of fibrosis regression. Therefore, future studies are needed to validate noninvasive methods in predicting the different phases of liver cirrhosis.

Lactoferrin is an antimicrobial prote in characterized by the exertion of many protective functions,including antibacterial,antifungal,antiviral,and antiparasitic properties,as well as anti-inflammatory and immunomodulatory activities(Kruzel et al.,2017).Lactoferrin is one of the major proteins present in exocrine secretions,including saliva,and is therefore associated with host defense against oral pathogens and control of the oral *** recent years,it has become clear that alterations in the oral microbiome may contribute to opportunistic pathogen infections in the brains of Alzheimer’s disease(AD)patients and thus participate in or contribute to the development of this neurodegenerative disease(Sureda et al.,2020).Pathogenic oral microbes can affect neurological processes by entering brain tissue through various pathways and directly damaging the central nervous *** the central nervous system,oral microbes may trigger an immune response that increases amyloidβ(Aβ)production and may even trigger the Aβcascade to promote the onset of AD,as we discuss in our previous study supporting the“infectious hypothesis”in AD(González-Sánchez et al.,2020).
