Analysis of Ancient Glass Using Ion Beams and Related Techniques
Authors: Kossionides S. , Kokkoris M. , Karydas A. G. , Paradellis T. , Kordas G. , Moraitou G.
Published: February 2020

Ion Beam Analysis (IBA) techniques are established as an indispensable tool for material analysis. They are very powerful when applied to the examination of uniform layers. In recent years they have been also used for the quality control of implanted layers, which improve the mechanical or chemical properties of common materials. The use of IBA techniques for the study of corrosion is impeded by the non-uniformity of such layers, which renders the analysis difficult. In the Material Analysis Laboratory of the Institute of Nuclear Physics, a combination of experimental techniques and analytical algorithms has been developed, which allows the non-destructive examination of corrosion layers on cultural artifacts. Ancient glass fragments from Kenchreai, Greece, were analyzed with ion beam techniques, in order to examine the applicability of the latter to the characterization of the surface. The relative distribution of heavy components was determined by X-Ray Fluorescence (XRF). Nuclear reactions were used to determine the depth distribution of H, O, C and Si. The Hydrogen distribution rises sharply from the surface, reaching a maximum of 9xl022 at/cm3 at 0.5 μπι and then decays smoothly to a depth of approximately 2 μπα. Examination of the same samples with aparticles, indicates a depletion of Silicon in the same surface region, while the Oxygen distribution is uniform. A detailed analysis, using the 28Si(p, p) reaction, which resonates at 2.095 MeV, confirms the depletion and other non-uniformities in the Silicon distribution.
Deformed Hartree-Fock calculations for semileptonic processes in nuclei
Authors: Kosmas T. S.
Published: February 2020

In nuclear structure calculations, the Deformed Hartree-Fock (DHF) provides generally a good description for the low-lying spectroscopic properties of odd-even, odd-odd and even-even nuclear systems of which the consideration of the deformation is motivated by many reasons. The common random phase approximations (RPA, QRPA, etc.) mostly used to accurately evaluate the transition matrix elements in many nuclear processes [1,2], are appropriate for only spherical even-even nuclear systems even though, sometimes, isotopes considered as rather deformed are studied. In the present work, we discuss the treatment within the DHF method of nuclei in the region A = 70 — 80. This region includes isotopes (like 72Ge, 76Ge, 72Se, etc) interesting for studying many nuclear processes as the ,0/3-decay, scattering of dark matter candidates off nuclei, μ~ —> e± conversions in nuclei. In our calculations the model space comprises 1P3/2, 0f5/2, 1pi/2 and 0p9/2 single particle Orbitals assuming 56Ni to be the inert core. The effective interaction employed, has been quite successfully used previously to describe many important features of the nuclei in this region. The lowest prolate Hartree-Fock single particle spectrum of some isotopes (72Ge, 76Ge) has been used to test the good angular momentum states which in this method are projected out from the intrinsic HF states. As an application, we examine the predictions of DHF for the exotic (μ~,ε~) conversion process. The contributions of all basic μ~ —> e~ operators originating from a general effective Lagrangian [2] are compared with those of normal QRPA methods obtained previously.

The neutron facility at the 5.5 MV Tandem Tll/25 accelerator of NCSR "Demokritos" has been used to produce monoenergetic neutron beams in the energy range 120-650 keV and 4-11.5 MeV via the 7Li(p,n) and 2H(d,n) reactions, respectively. The flux variation of the neutron beam was monitored by using a BF3 detector, while an investigation of the energy dependence of the neutron fluence has been carried out with a liquid scintillator BC501A detector as well as with the multiple foil activation technique. The 232Th(n,2n)231Th and 241Am(n,2n)240Am as well as (n,2n), (n,p) and (η,α) reactions on natural Ge and Hf isotopes, have been investigated from threshold up to 11.5 MeV, by using the activation method.
Analytic description of critical point actinides in a transition from octupole deformation to octupole vibrations
Authors: Bonatsos Dennis , Lenis D. , Minkov N. , Petrellis D. , Yotov P.
Published: February 2020

An analytic collective model in which the relative presence of the quadrupole and octupole deformations is determined by a parameter (φο), while axial symmetry is obeyed, is developed. The model [to be called the analytic quadrupole octupole axially symmetric model (AQOA)] involves an infinite well potential, provides predictions for energy and Β (EL) ratios which depend only on φο, draws the border between the regions of octupole deformation and octupole vibrations in an essentially parameter-independent way, and describes well 2 2 6Th and 226Ra, for which experimental energy data are shown to suggest that they lie close to this border. The similarity of the AQOA results with φο = 45° for ground state band spectra and B(E2) transition rates to the predictions of the X(5) model is pointed out.

Authors: Bonatsos Dennis , Lenis D. , Petrellis D. , Terziev P. , Yigitoglu I.
Published: February 2020

A γ-rigid solution of the Bohr Hamiltonian for 7 = 30° is derived, its ground state band being related to the second order Casimir operator of the Euclidean algebra E(4).

Spallation neutron sources provide more intense and harder neutron spectrum than nuclear reactors for which a substantial amount of shielding measurements have been performed. Although the main part of the cost for a spallation station is the cost of the shielding, measurements regarding shielding for the high energy neutron region are still very scarce. In this work calculation of the neutron interaction length in polyethylene moderator for different neutron energies is presented. Measurements which were carried out in Nuclotron accelerator at the Laboratory of High Energies (Joint Institute for Nuclear Research, Dubna) and comparison with calculation are also presented. The measurements were performed with Solid State Nuclear Track Detectors (SSNTDs).

The design of innovative Accelerator Driven Systems (ADS) for incineration of nuclear waste and energy generation requires the complete knowledge of basic cross sections for neutron induced processes. The main goal of the project is to produce, evaluate and disseminate high precision cross sections for the majority of the isotopes relevant to the waste incineration and the ADS design i.e. capture and fission cross sections for the minor actinides, capture cross sections for the main fission products and (η,χη) reactions for structural and coolant materials. The most recent work, (2003-2004 campaign) took place at CERN, using a Total Absorption Calorimeter (TAC) in neutron capture measurements. The TAC was build at n_TOF facility and consists of 40 BaF2 crystals, covering an almost 4π geometry. Several targets of special interest have been measured, such as 233>234U, 241Am, 237Np, 2 4 0Pu and samples for reference and background determination as well (197Au, 2 0 8Pb, natC). Preliminary results of 2 3 7Np and 2 4 0Pu and 2 3 4U will be presented, indicating the good performance of the n_TOF facility, DAQ (Data Acquisition system) and TAC, allowing even more ambitious experiments in the future.

Superdeformation in Pb isotopes with large neutron excess
Authors: Daoutidis J. , Lalazissis G. A.
Published: February 2020

Covariant Density Functional theory (CDFT) is used to investigate superdeformation in Pb isotopes on the neutron rich side of the periodic table. Energy surfaces and deformation parameters in this region are calculated by solving the constrained Relativistic Hartree Bogoliubov (RHB) equations. We use the parameter set DDME2, which has an explicit density dependence as well in the isoscalar as in the isovector channel together with the finite range pairing force DIS of Gogny. With increasing neutron number we find a characteristic pattern for superdeformed minima in these nuclei.

Published: February 2020

The role of short-range correlations on the depletion of the Fermi sea is studied in light nuclei.The short range correlations are considered in an approximate treatment allowing a systematic study of nuclei in the region 4 < A < 40. The "natural orbital" representation is used for the determination of the occupation probabilities of the shell model orbits of the ground state wave function. The depletion of the nuclear Fermi sea appears to be, on the average, about 32%.

Neutron deficient nuclei close to 100Sn have been investigated in-beam by particle and γ-ray spectroscopic methods using the NORDBALL detector array following the bombartment of a 54Fe target with a beam of 270 MeV 58Ni. Protons and α particles were identified with a 4π ΔΕ-type Si-multidetector and neutrons with a 1π liquid-scintillator-detectorassembly placed in the forward derection. Excited states of 102In were identified for the first time. The level scheme constructed from γ-γ-particle-coincidence and γ angular correlations is discussed and compared to the structure of neighboring nuclei in the framework of the nuclear shell model.
Effects of Short and Long Range Correlations on the Charge Densities and Radii of Ca Nuclei
Authors: Lalazissis G. A. , Massen S. E.
Published: February 2020

The experimental data for the charge (proton) density differences of the even Ca nuclei is analyzed by means of a simple phenomenological model where the effects of certain type short and long range correlations have been accounted. Short range correlations are approximated through the Jastrow type correlation function while for long range correlations the fluctuations of the nuclear surface are considered. The analysis shows that the combined effects of these correlations lead to a better description of the experimental charge (proton) density differences. Moreover, the calculated charge mean square radii of the even Ca nuclei exhibit a parabolic behaviour and compare well with the experimental isotope shifts from the laser spectroscopy measurements.
Collective Reactions in the Continuum
Authors: Demetriou P. , Marcinkowski A. , Hodgson P. E.
Published: February 2020

We show that pre-equlibrium inelastic scattering reactions to the continuum contain substantial collective components in addition to the multistep direct and multistep compound reactions. These collective reactions are investigated for the vibrational nuclei 56Fe, 58Ni, 90Zr, 93Nb, 208Pb and 209Bi , and the strongly-deformed, rotational W nucleus. The collective cross-sections are calculated using the experimental data for low-lying collective excitations supplemented where necessary by the giant multipole resonances evaluated using the energy-weight ed sum rule. The MSC and MSD cross-sections are evaluated by the Feshbach-Kerman-Koonin theory using a consistent set of parameters determined by analyses of (p, xn) reactions, that have practically no collective components. The results are compared with high-resolution neutron inelastic scattering data and prove able to account for the absolute magnitude of the cross-sections and also their detailed structure.

Published: February 2020

It was aim of this project the development of a low - cost system, managing signals coming - out of several detectors (ionization chambers, Nal - detectors, Geiger - Mueller etc.) installed in different areas, monitoring radiation levels. The output of such detectors is a spike - like waveform, that may be introduced to a Schmitt - trigger, producing equal frequency quadratic pulses, that are counted. Alternatively, the output may be introduced to an amplified waveform V(t), corresponding to the monitored rate, will be digitized through a PCL - 812PG A/D I/O card and introduced to a PC (at least 486 DX, 33MHz, 8 MB RAM). Custom - made (Pascal 7.0) software enables the display of the signal, threshold and alarm settings, as well as , hardware parameter settings (amplification, set – off voltage, sampling rate etc.). The system has been tested experimentally. Up to 5 detectors may be mounted to the card but the software supports up to 16. Up to 10000 cpm may be registered, because of the limits of the 400Hz antializing filter, the ADC speed and the MUX PCLD - 889 characteristics. The system may be used as a simple low - cost signal monitoring device, enabling the telemetrie transmission of the signals, if required.

Quantum phase transition phenomena in odd-A nuclei
Authors: Petrellis D.
Published: February 2020

Quantum phase transitions in even-even nuclei been extensively studied both in theory and experiment in the recent years. Odd-even nuclei can be considered as examples of mixed Bose-Fermi systems with a single fermion coupled to an even-even core. The eÆect of a fermion with angular momentum j on quantum phase transi- tions of a bosonic system comprised of s (L=0) and d (L=2) bosons is investigated. The analysis is based on an Interacting Boson Fermion Model (IBFM) Hamiltonian and its classical limit and it demostrates the changes in the energy level structure as well as the classical and quantum order parameters involved. Some experimental evidence is also presented and compared with theoretical calculations

Published: February 2020

Proof-of-principle inelastic proton scattering measurements have been performed at NCSR “Demokritos”. Excited states in 64Zn and 92Mo were populated using the (p,p'γ) reaction with E(p) = 7 MeV. The reaction γ rays were detected using four HPGe detectors at eight separate angles, with respect to the beam-axis. From Doppler-shift attenuation of the ∞ rays, lifetimes for eight excited states in 64Zn and for the Iπ = 2^+_2 and 2^+_3 states in 92Mo were deduced. The lifetimes measured in 92Mo are in good agreement with adopted values whereas the lifetimes measured in 64Zn are typically longer than the literature values. Development of the experimental set-up and potential novel physics cases where this reaction could be used are briefly discussed.

Radiotracer imaging studies for a small field, high resolution ∞-Camera system and a clinical system for Positron Emission Tomography (PET) by means of GATE (GEANT4 Application for Tomographic Emission) simulations are presented in this work. In a validation phase, which preceded the main study, experimentally obtained results for planar images with the existing ∞-Camera system were directly compared to simulated data. A simple phantom structure, consisting of four parallel capillaries filled with 99mTc water solution, was imaged by the γ-Camera system for several phantom-collimator distances and the measured and Monte-Carlo calculated spatial projections were compared. The major objective of this validation study was the optimal description of the most important components, the hexagonal, parallel-hole Pb-collimator and the pixelated CsI scintillation crystal of the γ-imaging system in terms of GATE components. In the main study, a GATE simulation setup for this ∞-Camera detector is used and Monte-Carlo data are accumulated for simple geometrical phantoms with different monophotonic radiotracer energies and relative intensities. In parallel, a commercially available cylindrical shaped PET scanner ring, consisting of 32 sectors with 4 x 6 x 6 LSO scintillation crystals, has been constructed in the GATE environment. Simulation data are obtained for the most usual positron emitters (18F, 11C and 15O) and for several phantom geometries. The spatial resolution of both systems and their overall performance is presented and discussed in this study.

Published: February 2020

In the present work we carry out an extensive study of the solar structure and solar evolution through the use of the TYCHO 6.92 code, which includes a variety of programs and subroutines. In this code we incorporate the most updated microphysical parameters such as screening, recent experimental measurements of the astrophysical factors-S (LUNA), several updated, recently measured, heavy element abundances, etc., and created new models describing crucial phenomena of the solar structure and solar evolution. We used this code to calculate and update nuclear reaction rates, solar neutrino fluxes, solar quantities which characterize the internal solar structure such as temperature, pressure, density, luminosity, heavy element abundances (4He, 12C, 14N, 16O, etc.) as well as sound speed profile and depth of the convection zone.
Approaching neutron-rich nuclei towards the r-process path in 86Kr-induced collisions at 15 MeV/nucleon
Authors: Souliotis G. A.
Published: February 2020

The production cross sections of projectile-like fragments from collisions of 15 MeV/nucleon 86Kr with 64,58Ni and 124,112Sn have been measured using a magnetic separator with emphasis on the neutron-rich isotopes. Neutron pick-up isotopes (with up to 6-8 neutrons picked-up from the target) were observed with large cross sections. The present results were also compared with our previous data of the same reactions at 25 MeV/nucleon. The data at 15 MeV/nucleon show enhanced production of neutron-rich isotopes very close to the projectile, relative to the corresponding data at 25 MeV/nucleon. The large cross sections of such reactions involving peripheral nucleon exchange, indicate that these reactions offer a novel route to access extremely neutron-rich rare isotopes towards the the astrophysical r-process path and the neutron-drip line.

Published: February 2020

The anthropogenic radionuclide 137Cs is used as a valuable oceanographic tracer for the study of sea water masses identification and water movement. In the present work, 137Cs activity concentrations have been investigated in deep basins of Aegean Sea. Seawater samples were collected from five different sampling stations, during scientific oceanic campaigns from the period March to April 2008. The applied methodology was based on the adsorption of radiocaesium from dissolved AMP (Ammonium Phosphomolybdate Hydrate) in 20 L water samples. Moreover, during the pre- concentration procedure, the 134Cs was used as reference tracer for determining the chemical efficiency and consequently to measure the activity concentration in a High Purity Ge detector. In terms of vertical records, the activity concentration in the selected basins ranged between 3-8.5 Bq/m3, depending on the region and the depth of the basins. The higher concentration (8.5 Bq/m3) was found in the region between Lemnos Island and the narrows of Dardanelles. The maximum concentrations were observed at the North Aegean Sea basins, between 20 and 40 m of depth, caused by the water masses coming from the Black Sea. At the Cretan Sea the vertical activity concentration of 137Cs was homogeneous down to 2000 m depth, with an exception at the 800 m where it was decreasing significantly due to the transient deep-water masses from Adriatic Sea.

Three superordinate themes were generated: learning by doing, mentorship and transition to qualification. The findings demonstrate the benefits of student midwife exposure to practical aspects of NIPE.

Conclusions

Findings indicate that standardisation is required with NIPE education and clinical practice. Preceptorship programmes must effectively prepare newly qualified midwives to undertake the NIPE role. Higher educational institutes must provide greater support to the midwives providing mentorship of student midwife NIPE practitioners. Further research should examine the maintenance of the NIPE role following qualification as a midwife.
Autonomy and its impact on midwifery practice
Authors: Zolkefli Zulfaa Humairaa Haji , Mumin Khadizah Haji Abdul , Idris Deeni Rudita
Published: February 2020

Objective

To explore the definition of autonomy, its significant features and impacts on midwifery practice.

Method

Combined keywords searched were performed on electronic databases: Scopus, Science Direct and Medline within EBSCOhost and Google Scholar. Data were extracted and analysed corresponding to the objectives of this review.

Findings

A total of eight studies (n=8) were included (one quantitative and seven qualitative). Autonomy is the central element in midwifery that is commonly linked with informed choices; decision-making and power to control over a situation. In order for a midwife to be autonomous, important attributes include knowledge and skills (being confident, and the ability to think critically). It was also found that infrastructure and culture at work impacts autonomy in midwifery practice.

Conclusion

Albeit a limited number of studies were included in the review, this review provides an important platform for understanding the principles and concepts that underpin autonomy in midwifery practice.

Selective Catalytic Oxidation of Aldehydes by a Molybdenum System
Authors: El Amrani Ikram , Atlamsani Ahmed
Published: February 2020

The oxidation of aldehydes with molecular oxygen was investigated in the presence of MoO2(acac)2(Bis(acetylacetonato)dioxomolybdenum(VI)), and under mild condition (temperature and pressure). In the oxidation reaction system, the effect of the catalyst has been evaluated. In addition, the factor of solvents was deeply discussed. The process is particularly selective for linear and aromatic aldehydes. Finally, the use of environmentally-friendly oxidation system, including mild conditions and inexpensive oxidant, can make this process very attractive in the fine chemical synthesis.
Knowledge generation and former carers: reflections and ways forward
Authors: Larkin Mary , Milne Alisoun
Published: February 2020

While their increasing number is achieving some academic and public recognition, former carers occupy a liminal status, are often hidden, and experience a range of negative legacies related to caring. Existing research on former carers is limited in both quantity and quality, and former caring tends to be viewed as an end stage of the overall caring trajectory. A number of theories and concepts employed to enrich the wider carers field have the potential to extend understanding about the needs, situations and lived experiences of former carers and to generate new knowledge about former caring as a process and a transition. These include feminist perspectives, lifecourse analysis, the ethic of care, the emotiospatial hermeneutic, emotional labour, social liminality, hybridity, biographical disruption and social identity. The article aims to open up debate about former carers and act as a platform for taking forward developments in research.
Near-infrared light driven tissue-penetrating cardiac optogenetics via upconversion nanoparticles in vivo

Published: February 2020

This study determines whether near-infrared (NIR) light can drive tissue-penetrating cardiac optical control with upconversion luminescent materials. Adeno-associated virus (AAV) encoding channelrhodopsin-2 (ChR2) was injected intravenously to rats to achieve ChR2 expression in the heart. The upconversion nanoparticles (UCNP) NaYF4:Yb/Tm or upconversion microparticles (UCMP) NaYF4 to upconvert blue light were selected to fabricate freestanding polydimethylsiloxane films. These were attached on the ventricle and covered with muscle tissue. Additionally, a 980-nm NIR laser was programmed and illuminated on the film or the tissue. The NIR laser successfully captured ectopic paced rhythm in the heart, which displays similar manipulation characteristics to those triggered by blue light. Our results highlight the feasibility of tissue-penetration cardiac optogenetics by NIR and demonstrate the potential to use external optical manipulation for non-invasive or weakly invasive applications in cardiovascular diseases.
Glocalization, bricolage and black metal: Towards a music-centric youth culture simultaneously exemplifying the global and the glocal
Authors: Hoffin Kevin
Published: February 2020

This article aims to show how youth subculture is mapped onto both ‘global’ and ‘glocal’ terms. The progression of the article is as follows: from a basic overview of youth subculture, black metal and current research, it then begins to slowly unpack; using familiar examples of globalization, in business and of culture. The article introduces how globalization and bricolage have intertwined to create ‘glocalization’, and how this new way to view global communities has pushed our current ideas of youth subculture towards evolution. The article hopes to encourage re-analysis in how we think of youth subculture; away from monolithic tribes towards more subtly nuanced groupings.
From The Wicker Man (1973) to Atlantean Kodex: Extreme music, alternative identities and the invention of paganism
Authors: Spracklen Karl
Published: February 2020

The German epic heavy/doom metal band Atlantean Kodex has written two concept albums based on the folklore and paganism of old Europe and the West: The Golden Bough and The White Goddess. The two albums owe their titles to two books that have influenced the rise of modern paganism, though they remain deeply problematical. In this article, I explore possibly the most important influence on Atlantean Kodex, which is also one of the most important influences on modern paganism: the 1973 horror film The Wicker Man. I discuss the ways in which the film uses the speculative folklore of Frazer and Graves to construct a set of invented traditions about paganism and its alternative, counter-Christian nature, which have made paganism appealing to extreme metal musicians and fans. In this discussion, I use examples from other metal bands and fans who have name-checked the themes and the traditions of the film. In discussing the folklore of the Wicker Man, I also explore the folk music used in the soundtrack, which has also contributed to the invention of modern paganism and extreme folk music. I conclude by suggesting that, although many pagans have adopted this extreme music and myth into their world-views, the myth of the Wicker Man is also used as a playful rejection of Christianity and its authority by those of a secular or humanist persuasion.
Risk for Colorectal Neoplasia in Patients With Helicobacter pylori Infection: A Systematic Review and Meta-analysis
Authors: Choi Da Sol , Seo Seung In , Shin Woon Geon , Park Chan Hyuk
Published: February 2020

OBJECTIVES:

Helicobacter pylori may reportedly be associated with extragastric malignancy beyond gastric cancer. The present study aimed to evaluate the association between H. pylori infection and colorectal neoplasia through a systematic review and meta-analysis.

METHODS:

The literature search aimed to retrieve all relevant studies published up to September 2019 that examined the risk for colorectal neoplasia including colorectal adenoma, advanced adenoma, and cancer in patients with H. pylori infection. Meta-analysis was performed to calculate pooled odds ratios (ORs) with corresponding 95% confidence intervals (CIs). If publication bias was observed, the pooled OR was adjusted using the trim-and-fill method.

RESULTS:

Forty-eight studies including 171,045 patients were evaluated, of which 24, 8, and 31 reported H. pylori-associated risk for adenoma, advanced adenoma, and cancer, respectively. H. pylori infection was associated with a significantly higher risk for colorectal adenoma (pooled OR 1.49 [95% CI 1.37–1.62]). H. pylori infection was also associated with a higher risk for advanced colorectal adenoma (pooled OR 1.50 [95% CI 1.28–1.75]). The risk for colorectal cancer in patients with H. pylori infection was also identified (pooled OR 1.44 [95% 1.26–1.65]). Although publication bias was identified in the analysis for colorectal adenoma, the pooled estimate was not significantly changed after adjustment (pooled OR 1.39 [95% CI 1.27–1.52]).

DISCUSSION:

Although this meta-analysis based on the observational studies could not show causality, it demonstrated that colorectal adenoma, advanced adenoma, and cancer were all associated with H. pylori infection.
ON THE RESTORATION OF THE KINEMATIC ACCURACY OF LARGE-SIZE ROTARY-DRIVE DEVICE LONG TIME ABANDONED
Authors: Samsonovich S. L. , Fedotov B. K. , Goryunov R. V.
Published: February 2020

Restoration of the rotary-drive device after a long non-use is an important strategic task, and the search for a way to restore it is an urgent task of the study. Previously it was found that the long-term non-use of the rotary-drive device led to a deterioration in the kinematic accuracy of its gearboxes. This article discusses possible options for restoring the kinematic accuracy of gearboxes of the rotary-drive device by increasing the metal or introducing into the control system an electromechanical device for selecting the backlash. It is shown that the restoration of the geometry of gears, as well as the bearing seats is possible, however, it requires the use of specialized equipment and significant costs. Ensuring the required kinematic accuracy due to the introduction of an electromechanical choice of backlash is achieved by considering the two schemes of the backlash-picker. The performed simulation of the operation of the drive system with an electromechanical choice of backlash in the Simulink system showed that the use of a scheme with cross-links allows for the required kinematic accuracy without significant costs. As a result, it can be argued that the introduction of an electromechanical backlash device can restore the kinematic accuracy of the rotary-drive device to acceptable values.

Authors: Syasko V. A. , Golubev S. S. , Musikhin A. S.
Published: February 2020

The high voltage spark testing method of protective dielectric coatings is applied in almost all manufacture areas and is governed by ISO, ASTM etc. However, all of it doesn’t pay proper attention to high voltage forming (DC or AC) and its polarity relative to electrode, influence of environment and electric field inhomogeneity. In that paper a detailed analysis of air gap breakdown forming processes was given. A dependence of electric field strength on an interelectrode gap length was given for homogeneous and highly inhomogeneous electric fields. It was shown a breakdown voltage of air gaps in highly inhomogeneous field is greatly less than in homogeneous field. Also, it is described the breakdown voltage of air gaps with positive polarity is less then with negative polarity. The possibility coatings testing with a minimum thickness up to 50 m while reducing the testing voltage without reducing the reliability of the results is shown.
RESONANCE ULTRASONIC LASER VIBROMETRY OF MISCELLANEOUS DEFECTS IN GLASS FIBER REINFORCED PLASTIC
Authors: Derusova D. A. , Vavilov V. P.
Published: February 2020

It is demonstrated that, by using the technique of resonance ultrasonic laser vibrometry, the detectability of inserts of different nature strongly depends on an insert material and its location in a test object made of glass fiber reinforced plastic. The best inspection results have been obtained by providing a two-sided access to the test object with further combining results of vibroscanning obtained at different (resonance) frequencies. The most appropriate defects for applying the technique of laser vibrometry are discontinuities, such as voids and delaminations, which significantly change sample local rigidity.
