Diagnosis of Tendinites in Sport Horses

Sports horses during training and sporting events get injured to both the thoracic and pelvic limbs in the area of the metacarpus and metatarsus. In this regard, for the differential diagnosis of defeat tendon and ligament and other defeats of the limbs, biochemical blood parameters have been explored related to inflammation markers by visual studies in addition to clinical assessment of the intensity of inflammatory processes. Inflammatory processes in the animal’s body are judged by the results of aspirin test, by the level of molecules of average weight, sialic acids, circulating immune complexes. The research revealed changes in the blood of sick horses relatively to healthy ones. Some indicators of markers of inflammation were different: so indicators of aspirin test in the blood of sick animals it was at the level of – 0.028±0.002 c.u. in the blood of healthy animals it was – 0.015±0.002 c.u.; molecules of average weight in diseased animals were level – 0.216±0.009 c.u. and in healthy animals, this indicator was significantly lower and were 0.134±0.004 c.u.; index of sialic acid in the blood of sick animals was at the level of – 2.136±0.059 mmol/l, and in healthy horses – 0.419±0.027 mmol/l; circulating immune complexes in the concentration of PEG – 4.14% in sick horses were – 0.097±0.009 c.u. and in healthy – 0.149±0.011 c.u., at PEG 7.25 % in sick animals reached – 0.343±0.015 c.u. and – 0,174±0,011 c.u. in healthy horses; the content of lysozyme in the blood of sick horses was 145.71±3.98 mg/l, and in healthy animals – 143.57±3.97 mg/l. These studies suggest that changes in these indicators associated with the pathology of tendon-ligamentous apparatus of the limbs of sport horses

Scanning Probe Techniques for Characterization of Vertically Aligned Carbon Nanotubes

This chapter presents the results of experimental studies of the electrical, mechanical and geometric parameters of vertically aligned carbon nanotubes (VA CNTs) using scanning probe microscopy (SPM). This chapter also presents the features and difficulties of characterization of VA CNTs in different scanning modes of the SPM. Advanced techniques for VA CNT characterization (the height, Young’s modulus, resistivity, adhesion and piezoelectric response) taking into account the features of the SPM modes are described. The proposed techniques allow to overcome the difficulties associated with the vertical orientation and high aspect ratio of nanotubes in determining the electrical and mechanical parameters of the VA CNTs by standard methods. The results can be used in the development of diagnostic methods as well as in nanoelectronics and nanosystem devices based on vertically aligned carbon nanotubes (memory elements, adhesive structures, nanoelectromechanical switches, emission structures, etc.)

Resistive Switching of GaAs Oxide Nanostructures

The paper presents the results of experimental studies of the influence of the local anodic oxidation control parameters on the geometric parameters of oxide nanoscale structures (ONS) and profiled nanoscale structures (PNS) on the surface of epitaxial structures of silicon doped gallium arsenide with an impurity concentration of 5 × 1017 cm−3. X-ray photoelectron spectroscopy measurements showed that GaAs oxide consists of oxide phases Ga2O3 and As2O3, and the thickness of the Ga2O3 layer is 2–3 times greater than the thickness of As2O3 area—i.e., the oxidized GaAs region consists mainly of Ga2O3. The experimental studies of the influence of ONS thickness on the resistive switching effect were obtained. An increase in the ONS thickness from 0.8 ± 0.3 to 7.6 ± 0.6 nm leads to an increase in the switching voltage Uset from 2.8 ± 0.3 to 6.8 ± 0.9 V. The results can be used in the development of technological processes for the manufacturing of nano-electronic elements, such as ReRAM, as well as a high-efficiency quantum dot laser

A co-harmonic gyro-monotron with a novel corrugated interaction cavity

A novel interaction cavity has been designed for a gyro-monotron, allowing co-harmonic generation at the 2nd and 4th harmonic resonances of the cyclotron frequency. The output aperture of the cavity has been designed to trap the lower harmonic, whilst allowing output of the upper harmonic. Results from recent numerical simulations, performed using MAGIC 3-D, are presented. The intended co-harmonic behaviour is observed, with simultaneous excitation of the 2nd and 4th harmonics. Refinement of the output structure is now being undertaken to ensure only the 4th harmonic signal is emitted
