A method for detecting excitations leading to the damage of the gears and bearings working surfaces has been developed by nunchaku means of experimental study of the dynamic characteristics of the metro tunnel escalator drive gearbox in normal and bad performance.The technique is based on the acquisition and analysis of low and high resolution spec
In this investigation, three Angora Goats of 3 years old and with the permanent rumen cannula were used.The goats were fed with alfalfa hay (40%) and the pelleted white beet pulp (60%).The first animal was used as a control and 1 g and 2.4 g phosphorus were infused via rumen cannula into rumen of the second and third animals respectively.Rumen cont
Background: Additive manufacturing (AM) is a fast-developing technology with possible applications in cardiology.Existing research has identified two general factors that can influence implementing AM in cardiology: economics and technology.Objective: In this study we aimed to identify barriers and facilitators to implementing AM in cardiology.Meth
Most cells exchange ions and small metabolites via gap junction channels.These channels are made of two hemichannels (connexons), each formed by the radial arrangement of six connexin (Cx) proteins.Connexins span the bilayer four times (M1-M4) and have both amino- and carboxy-termini (NT, CT) at the cytoplasmic side of the membrane, forming two ext
