NFFA-Europe Pilot - D9.1 - Deployment of the VA service prototypes

This Deliverable presents the prototype of the first Virtual Access service: an instance of the MetaStore, named MetaRepo. The service has been installed as a virtual machine hosted at KIT, and has been connected to the Single-Sign-On. The service can be accessed using a Graphical User Interface. A monitoring service on the MetaRepo side makes a call to the API of the database test instance at each action performed in the MetaRepo by logged-in users, in order to keep track of the activities of the Virtual Access service

Some aspects of the human body's hydraulics

This paper presents some aspects related to the human body's hydraulics in the desire to make readers aware of how to maintain all the blood vessels of the human body in order to maintain the entire healthy, functional, young, vigorous circulatory system for a while the longest possible. The problem is complex because it has to be viewed from all points of view and not only as an isolated system in the body, having aspects of feedback on the whole physiopathology belonging to the human body. The highly circulating system needs permanent maintenance. Self-maintenance is done through various physiological mechanisms tightly linked to each other, including the lymphatic, digestive, renal, lung, nervous, glandular system… It is not possible to completely separate the physiology of a system from the other adjacent systems because they all work synergistically, being permanently controlled by the central and peripheral nervous system

Mitochondria are naturally micro robots - A review

The mitochondrion is a natural robot (cell) with a length of about one micron. Between organisms (plant, animal or human) with its organs and the atomic and molecular components are positioned based cells, which are building all the necessary organs body. Years ago, medical specialists who are studying organ disease have considered that is caused by impaired organ or related to other organs. For example, it was considered that all nerve diseases have started from stress due to disorder of the hypothalamic-pituitary-adrenal (adrenal glands). Today one knows that psychological stress triggers some metabolic, inflammatory and transcriptional perturbations that ultimately dispose to malady in cellular energetics, involving mitochondrial energy production respiratory stress. Future research on mitochondrial can lead to the elucidation of great issues of life (including the generation of illness, aging and death bodies). The main idea of this paper is that mitochondria are independent cells, flexible, essential for complex life

Future medicine services robotics

It is an entry technique in use recently, albeit in selected centers and represents a further step in the field of minimally invasive surgery. Basically it has the same indications but, at present, is reserved for selected patients. Compared to traditional video-assisted surgery presents some important differences. The surgeon is physically distant from the operative field and sits at a console, equipped with a monitor, from which, through a complex system, controls the movement of the robotic arms. These are fixed the various surgical instruments, tweezers, scissors, dissectors, that team shall present to the operating table to introduce into the cavity operative site. The use of mechanical arms has the advantage of allowing a three dimensional view an image with more stops and to make the most delicate maneuvers purposes and also because the tools are articulated to the distal end. The disadvantage is related to the times longer operative and the difficulty of determining the strength (as can happen in giving the right tension to a surgeon's knot). In the future it can be assumed that robotic surgery will allow, with the development of the experience, the spread of the equipment and improvement of telecommunication systems and data, to operate at ever greater distances. If you think that today, the space centers, you can operate the robots sent to the moon or farther away, it is not hard to believe that it will become usual to operate from side to side of the area, providing you with all the best and specific skills. The first surgical robot called da Vinci, in honor of Leonardo da Vinci, was developed in Silicon Valley by Intuitive Surgical and in 2000 he obtained the authorization of the American Food and Drug Administration (FDA) for use in laparoscopic surgery. The present paper wishes to show briefly several models of the main robots placed in the service of human medicine

One-Loop Corrections to Two-Quark Three-Gluon Amplitudes

We present the one-loop QCD amplitudes for two external massless quarks and three external gluons ($\bar{q}qggg$). This completes the set of one-loop amplitudes needed for the next-to-leading-order corrections to three-jet production at hadron colliders. We also discuss how to use group theory and supersymmetry to minimize the amount of calculation required for the more general case of one-loop two-quark $n$-gluon amplitudes. We use collinear limits to provide a stringent check on the amplitudes.Comment: plain Tex, 46 pages with 13 figures in a uuencoded file, corrected case j=1 of eq. (IV.7), and signs in eq. (4.9

Biomechanically tunable nano-silica/p-hema structural hydrogels for bone scaffolding

Innovative tissue engineering biomimetic hydrogels based on hydrophilic polymers have been investigated for their physical and mechanical properties. 5% to 25% by volume loading PHEMA-nanosilica glassy hybrid samples were equilibrated at 37◦C in aqueous physiological isotonic and hypotonic saline solutions (0.15 and 0.05 M NaCl) simulating two limiting possible compositions of physiological extracellular fluids. The glassy and hydrated hybrid materials were characterized by both dynamo-mechanical properties and equilibrium absorptions in the two physiological-like aqueous solutions. The mechanical and morphological modifications occurring in the samples have been described. The 5% volume nanosilica loading hybrid nanocomposite composition showed mechanical characteristics in the dry and hydrated states that were comparable to those of cortical bone and articular cartilage, respectively, and then chosen for further sorption kinetics characterization. Sorption and swelling kinetics were monitored up to equilibrium. Changes in water activities and osmotic pressures in the water-hybrid systems equilibrated at the two limiting solute molarities of the physiological solutions have been related to the observed anomalous sorption modes using the Flory-Huggins interaction parameter approach. The bulk modulus of the dry and glassy PHEMA-5% nanosilica hybrid at 37◦C has been observed to be comparable with the values of the osmotic pressures generated from the sorption of isotonic and hypotonic solutions. The anomalous sorption modes and swelling rates are coherent with the difference between osmotic swelling pressures and hybrid glassy nano-composite bulk modulus: the lower the differences the higher the swelling rate and equilibrium solution uptakes. Bone tissue engineering benefits of the use of tuneable biomimetic scaffold biomaterials that can be “designed” to act as biocompatible and biomechanically active hybrid interfaces are discussed

From structural colors to super-hydrophobicity and achromatic transparent protective coatings: Ion plating plasma assisted TiO2 and SiO2 nano-film deposition

The implementation of the Ion Plating Plasma Assisted technology in the area of surface functionalization for structural color and relic preservation applications is presented. Interferometric structural colors on irregular bumped Titanium surfaces and transparent and achromatic nano films on ancient ceramic artifact have been investigated. Titanium metal and ceramic supports have been utilized for the surface functionalization tests: A metallic electron beam additive manufactured Titanium component and an ancient tile of the XIX century, which was characterized by strong chromatic valence and by a mixed porous and glazed surfaces, have been considered. A reactive magnetron sputtering Ion Plating Plasma Assisted apparatus operating in Argon or Oxygen atmospheres for TiO2 and SiO2 deposition has been utilized. Preliminary tests with two plasma treatments were carried out for optimal processing conditions definition. TiO2 nano-film deposition on irregular Ti surfaces has generated light direction depending color-changing surfaces while good achromatic and transparent coatings were obtained by using SiO2 coating. The high processing flexibility of the Ion plating technology is discussed. The SiO2 IPPA surfaces treatment resulted more convenient for restorative and preservation ancient historical tile was used to finally test the optimized process with Ion Beam Electron Microscopy, which was carried out on the tile porous structure, confirmed the high flexibility and efficiency of the innovative IPPA technology
