    Thermodynamics of two lattice ice models in three dimensions

    Full text link
    In a recent paper we introduced two Potts-like models in three dimensions, which share the following properties: (A) One of the ice rules is always fulfilled (in particular also at infinite temperature). (B) Both ice rules hold for groundstate configurations. This allowed for an efficient calculation of the residual entropy of ice I (ordinary ice) by means of multicanonical simulations. Here we present the thermodynamics of these models. Despite their similarities with Potts models, no sign of a disorder-order phase transition is found.Comment: 5 pages, 7 figure

    The incidence of combat abdominal trauma ranges from 6.7 to 9%. The nature of gunshot abdominal wounds leads to the development of functional disorders and complications (51–81%) and, as a result, a high mortality rate (12–31%). The purpose of the work is to improve the effectiveness of surgical treatment of purulent-septic complications in wounded patients with combat abdominal trauma (CAT). We analysed the treatment of 86 wounded patients with purulent-septic complications of CAT who were hospitalized at the Military Medical Clinical Centre of the Southern Region. Taking into account the location, clinical manifestations and severity of the injury, modern methods of treatment were used, namely: puncture-drainage interventions under ultrasound guidance and the NPWT system installation. The complex treatment was supplemented with antibacterial therapy and oxygen barotherapy. First of all, the wounded patients underwent US-guided puncture, drainage interventions and stage debridement for diagnostic and therapeutic purposes. NPWT therapy was used in 11 patients with large wounds and purulent-septic complications of the soft tissues of the anterior abdominal wall. So, the use of interventional ultrasound as a priority diagnostic and therapeutic method for purulent and inflammatory complications of combat abdominal trauma improved the quality of diagnosis and reduced the number of traumatic interventions, which led to a decrease in postoperative complications and the duration of inpatient treatment. 11 (14.2%) cases of puncture-drainage interventions were ineffective, and therefore it was necessary to use traditional methods of treatment — opening and draining purulent-inflammatory foci and using NPWT therapy. Vacuum therapy is an effective method of treating purulent-septic complications of gunshot wounds of the abdominal soft tissues, which, in combination with puncture-drainage interventions, can 2.5 folds reduce the number of recurrent operations (mainly multistage surgical procedures), thereby 1.8 folds reducing the length of hospital stay. The use of current methods has improved the results of surgical treatment of purulent-septic complications in wounded patients with purulent-septic complications of combat abdominal trauma. The use of the current techniques helped to reduce the number of invasive treatment methods, facilitated recovery, reduced bed days, reduced intoxication, and increased the percentage of recovered military personnel

    Stevia rebaudiana Bertoni is a perennial herbal species with a number of therapeutic properties. The leaves of S. rebaudiana are the most important part of the plant as they contain high level of sweetener compounds known as steviol glycosides; which are known to possess antioxidant, antimicrobial, and antifungal activities. Among the steviol glycosides, stevioside and rebaudioside A are the most abundant sweetening compounds of interest, documented to be 30 - 250 folds sweeter than sucrose or refined sugar. The therapeutic properties of the species make it more interesting as they play important roles as anti hyperglycaemic agent to lower glucose levels in the blood, thus commonly used in the treatment of diabetes mellitus and obesity. Known to have sweet tasting leaves, its extract which contains antioxidant compounds have been used to treat cancer, reduce inflammatory, and hypertension. S. rebaudiana has drawn the attention of health-conscious fitness lovers all over the world as non-caloric sweetener, and has been widely cultivated for being the most suitable sweetening substitution

    Supercooled-liquid and plastic-crystalline state in succinonitrile-glutaronitrile mixtures

    Full text link
    We report a thorough characterization of the glassy phases of mixtures of succinonitrile and glutaronitrile via dielectric spectroscopy and differential scanning calorimetry. This system is revealed to be one of the rare examples where both glassy states of matter, a structurally disordered supercooled liquid and an orientationally disordered plastic crystal, can be prepared in the same material. Both disordered states can be easily supercooled, finally arriving at a structural-glass or a glassy-crystal state. Detailed investigations using broadband dielectric spectroscopy enable a comparison of the glassy dynamics in both phases. Just as previously demonstrated for supercooled-liquid and plastic-crystalline ethanol, our experiments reveal very similar relaxational behavior and glass temperatures of both disordered states. Thus the prominent role of orientational degrees of freedom in the glass transition, suggested on the basis of the findings for ethanol, is fully corroborated by the present work. Moreover, the fragilities of both phases are determined and compared for different mixtures. The findings can be well understood within an energy-landscape based explanation of fragility.Comment: 8 pages, 7 figure

    Optimum spectral window for imaging of art with optical coherence tomography

    Optical Coherence Tomography (OCT) has been shown to have potential for important applications in the field of art conservation and archaeology due to its ability to image subsurface microstructures non-invasively. However, its depth of penetration in painted objects is limited due to the strong scattering properties of artists’ paints. VIS-NIR (400 nm – 2400 nm) reflectance spectra of a wide variety of paints made with historic artists’ pigments have been measured. The best spectral window with which to use optical coherence tomography (OCT) for the imaging of subsurface structure of paintings was found to be around 2.2 μm. The same spectral window would also be most suitable for direct infrared imaging of preparatory sketches under the paint layers. The reflectance spectra from a large sample of chemically verified pigments provide information on the spectral transparency of historic artists’ pigments/paints as well as a reference set of spectra for pigment identification. The results of the paper suggest that broadband sources at ~2 microns are highly desirable for OCT applications in art and potentially material science in general

    Experimental study of a R290 variable geometry ejector

    Ejectors are classified as fluid-dynamics controlled devices where the "component-scale"performances are imposed by the local-scale fluid dynamic phenomena. For this reason, ejector performances (measured by the pressure-entrainment ratio coordinate of the critical point) are determined by the connection of operation conditions, working fluid and geometrical parameters. Given such a connection, variable geometry ejector represents a promising solution to increase the flexibility of ejector-based systems. The present study aims to extend knowledge on variable geometry systems, evaluating the local and global performances of the R290 ejector equipped with a spindle. The prototype ejector was installed at the R290 vapour compression test rig adapted and modified for the required experimental campaign. The test campaign considered global parameter measurements, such as the pressure and the temperature at inlets and outlet ports together with the mass flow rates at both inlet nozzles, and the local pressure drop measurements inside the ejector. In addition, the experimental data were gathered for different spindle positions starting from fully open position the spindle position limited by the mass flow rate inside the test rig with the step of 1.0 mm
