2Analysis of predictor equations for determining the blast-induced vibration in rock blasting显示文摘The paper proposes a new empirical correlation designed to complement the‘‘site laws'currently used to evaluate the attenuation in the rock masses of vibrations induced by rock blasting.The formula contains a deformed exponential known as the K-exponential,which seems to well represent a large number of both natural and artificial phenomena ranging from astrophysics to quantum mechanics,with some extension in the field of economics and finance.Experimental validation of the formula was performed via the analysis of vibration data covering a number of case studies,which differed in terms of both operation and rock type.A total of 12 experimental cases were analysed and the proposed formulation exhibited a good performance in 11 of them.In particular,the proposed law,which was built using blast test data,produced very good approximations of the points representing the vibration measurements and would thus be useful in organising production blasts.However,the developed formula was found to work less well when a correlation obtained for a given site was applied to another presenting similar types of rocks and operations,and thus should not be employed in the absence of measurements from test data.Marilena Cardu Dario Coragliotto Pierpaolo Oreste 2019International Journal of Mining Science and Technology2019,29,6:4
3Laboratory tests to study the influence of rock stress confinement on the performances of TBM discs in tunnels显示文摘To clarify some aspects of rock destruction with a disc acting on a high confined tunnel face, a series of tests were carried out to examine fracture mechanisms under an indenter that simulates the tunnel boring machine (TBM) tool action, in the presence of an adjacent groove, when a state of stress (lateral confinement) is imposed on a rock sample. These tests proved the importance of carefully establishing the optimal distance of grooves produced by discs acting on a confined surface, and the value (as a mere order of magnitude) of the increase of the thrust to produce the initiation of chip formation, as long as the confinement pressure becomes greater.N.

9Compromised nutritional status in patients with end-stage liver disease:Role of gut microbiota显示文摘Background: Patients with end-stage liver disease(ESLD) have a compromised nutritional status because of the liver crucial role in regulating metabolic homeostasis and energy balance.Data sources: A systematic review of literature based on extensive relevant articles published from 2001 to 2017 in English in Pub Med database was performed by searching keywords such as liver disease, nonalcoholic liver disease, alcoholic liver disease, malnutrition, epigenetics, gut microbiota, and probiotics.Results: Liver transplantation would be one eligible therapy for ESLD patients, even if, the clinical outcome is negatively influenced by malnutrition and/or infections. The malnutrition is a condition of nutrient imbalance with a high incidence in ESLD patients. An accurate evaluation of nutritional status could be fundamental for reducing complications and prolonging the survival of ESLD patients including those undergoing liver transplantation. In addition, the interaction among nutrients, diet and genes via epigenetics has emerged as a potential target to reduce the morbidity and mortality in ESLD patients. The malnutrition induces changes in gut microbiota causing dysbiosis with a probable translocation of bacteria and/or pathogen-derived factors from the intestine to the liver. Gut microbiota contribute to the progression of chronic liver diseases as well as hepatocellular carcinoma. The administration of probiotics modulating gut microbiota could improve all chronic liver diseases.Conclusions: This review provides an update on malnutrition status linked to epigenetics and the potential benefit of some probiotics on the management of ESLD patients. In support of this view and to reveal the constant and growing interest in this field, some clinical trials are reported.Maria Vasco Rossella Paolillo Concetta Schiano Linda Sommese Oreste Cuomo Claudio Napoli 2018Hepatobiliary & Pancreatic Diseases International2018,17,4:2
10Platelet biomarkers in Alzheimer's disease显示文摘The search for diagnostic and prognostic markers in Alzheimer's disease(AD) has been an area of active research in the last decades. Biochemical markers are correlates of intracerebral changes that can be identified in biological fluids, namely: peripheral blood(total blood, red and white blood cells, platelets, plasma and serum), saliva, urine and cerebrospinal fluid. An important feature of a biomarker is that it can be measured objectively and evaluated as(1) an indicator of disease mechanisms(markers of core pathogenic processes or the expression of downstream effects of these processes), or(2) biochemical responses to pharmacological or therapeutic intervention, which can be indicative of disease modification. Platelets have been used in neuropharmacological models since the mid-fifties, as they share several homeostatic functions with neurons, such as accumulation and release of neurotransmitters, responsiveness to variations in calcium concentration, and expression of membrane-bound compounds. Recent studies have shown that platelets also express several components related to the pathogenesis of AD,in particular to the amyloid cascade and the regulation of oxidative stress: thus they can be used in the search for biomarkers of the disease process. For instance, platelets are the most important source of circulating forms of the amyloid precursor protein and other important proteins such as Tau and glycogen synthase kinase-3B. Moreover, platelets express enzymes involved in membrane homeostasis(e.g., phospholipase A2), and markers of the inflammatory process and oxidative stress. In this review we summarize the available literature and discuss evidence concerning the potential use of platelet markers in AD.Leda L Talib Helena PG Joaquim Orestes V Forlenza 2012World Journal of Psychiatry2012,2,6:2
