Abstract

This article considers the influence of shear on a specimen with a crack-like defect (CRLD) as part of the general variational statement of the problem with a distinguished interactive layer. The delta-element fracture criterion is formulated as a generalized energy product (GEP), accounting for the influence of hydrostatic stress and the existence of an external boundary. The GEP convergence with a reduction of the layer thickness in the layers element is shown both in the simplified analytical solution and in the numerical solution by the finite elements method (FEM). The linear size determining the GEP convergence in the layers element is taken for the characteristic size of the finite element conjugate to the physical excision and its continuation. It is shown that, unlike the simplified analytical solution, the solution by FEM allows finding the maximum GEP outside the layer.

Abstract

The authors of the article considered a fracture model with a linear parameter (LP) associated with the thickness of the physical cut and the interaction layer (IL) on its continuation. With a zero value of the LP, the fracture model takes a form of a mathematical cut. The initial state of the body corresponds to the initial free binding energy, which is assumed to be negative. By the means of thermomechanical analysis of the fracturing processes, the authors established universal representation of the surface energy, which is valid for both physical and mathematical cuts. In the case of a physical cut, the surface energy is expressed as a product of multiplication of the LP value by the change in the specific free binding energy of the IL. It is called the energy product (EP). Using the proposed formulation, the authors considered the effect of decreasing LP on the critical state of samples of finite dimensions.

Abstract

We have studied the effect of interactions between dinitrosyl iron complexes with thiol-containing ligands (DNIC-TL) and diglucamine salt of chlorine e6 (photoditazine, PD) on the rate of photosensitized oxidation of a model organic substrate – tryptophan – in the presence and absence of an amphiphilic polymer, Pluronic F127, as well as on the DNIC-TL and PD photostability. Using EPR and UV spectroscopy, we determined the rate constants for photodegradation of mono- and dinuclear DNIC-TL and PD, respectively. The presence of the photosensitizer and Pluronic F127 has been shown to have a negligible effect on the rate of photodestruction of mono- and dinuclear DNIC-TL, taking into account the changing DNIC-TL and PD concentrations in the photoexcitation conditions. At the same time, in the DNIC-TL presence, the rate of PD photodestruction increases, however, addition of Pluronic F127 leads to a decrease in the rate constant of PD photodestruction. The latter circumstance creates an opportunity for a simultaneous application of DNIC-TL and photodynamic therapy in the wound treatment without losing the PDT efficiency. Indeed, photodynamic therapy in combination with DNIC-TL facilitated skin wound healing in laboratory rats. As shown by a morphological study, application of the DNIC-TL-PD-F127 complex with the subsequent photoactivation was beneficial in reducing inflammation and stimulating regenerative processes.

Abstract

Virginiamycin, a widely used veterinary antibiotic produced by Streptomyces virginiae, represents a natural mix of two macrocyclic peptidolactones; its main components are the M1 and S1 factors, which act synergistically when present in the optimum ratio of 75:25. Because of a large number of genes involved into the virginiamycin biosynthesis, the development of high-yield strains able to synthesize M1 and S1 at a synergistic ratio with the total productivity exceeding 4 g/L still remains a relevant problem. Using a multi-step random UV mutagenesis with the simultaneous control of the M1:S1 ratio in a final product, a new highly productive and genetically stable S. virginiae strain IB 25–8 was obtained. After the medium improvement combined with the addition of a Diaion™ HP21 resin absorbing up to 98.5% of the total virginiamycin, the productivity of the strain has reached 5.21 ± 0.16 g/L, while the M1:S1 ratio remained to be synergistic (75:25). The effect of various medium components, their concentration, and resin types on the M1:S1 ratio has been shown. The obtained strain is promising for the industrial use due to its high productivity and the optimal M1:S1 ratio. A pre-fermentation addition of the selected DIAION™ HP21 resin to fermentation medium increases the total yield and simplifies the further isolation and purification of virginiamycin.

Abstract

The use of advanced anti-icing materials is important to ensure and maintain the maximum traffic capacity, decrease the accident rate on motor roads exposed to adverse weather conditions in winter. The primary issue in applying these materials deals with ensuring the required traffic safety, therefore, these materials should undergo diagnostics before they can be recommended for use, and, subsequently, the condition of motor roads should be assessed. The diagnostic information obtained allows for comprehensive assessment of road operating conditions representing the most important factor in evaluating road pavement safety, especially in winter. The study addresses the issue of providing the basis for application of anti-icing materials to ensure the required safety on roads in winter. The study is focuses on road pavement operating conditions in winter, and the potential of using the new-generation anti-icing Nordway material and sand-and-salt mixture traditionally used in Russia’s periphery. As a result, due to the use of the new-generation anti-icing material, primary indicators of traffic safety assurance in winter are established. A full-scale experiment using the material under study is performed, primary cohesive properties for the experimental section of the road pavement are determined. Data on the braking distance variance in winter are gathered. A comparative analysis is carried out for a similar data set when using the traditional material, when using the tested material (of new generation) and without applying any materials. The most efficient way to reduce the accident rate on roads in winter using one of the anti-icing materials studied is established.

Abstract

In the events of peripheral dissociation of relativistic nuclei in the nuclear track emulsion, it is possible to study the emerging ensembles of He and H nuclei, including those from decays of unstable $^{8}$Be and $^{9}$B nuclei, as well as the Hoyle state. These extremely short-lived states are identified by invariant masses calculated from the angles in 2$\alpha$-pairs, 2$\alpha p$- and 3$\alpha$-triplets in the approximation of conservation of momentum per nucleon of the primary nucleus. In the same approach, it is possible to search for more complex states. This paper explores the correlation between the formation of $^{8}$Be nuclei and the multiplicity of accompanying $\alpha$-particles in the dissociation of relativistic $^{16}$O, $^{22}$Ne, $^{28}$Si, and $^{197}$Au nuclei. On the above basis, estimates of this correlation are presented for the unstable $^{9}$B nucleus and the Hoyle state. The enhancement in the $^{8}$Be contribution to dissociation with the $\alpha$-particle multiplicity has been found. Decays of $^{9}$B nuclei and Hoyle states follow the same trend.

Abstract

The Mu2e experiment at Fermilab searches for the coherent neutrino-less muon to electron conversion in the Coulomb field of an aluminum nucleus. This charged-lepton flavor violating process is characterized by a distinctive signature of a mono-energetic electron ( ∼ 105 MeV/c) and its observation will be a clear signature of new physics beyond the Standard Model. The Mu2e goal is to improve by four orders of magnitude the search sensitivity with respect to the previous experiments. The Mu2e detector is composed of a tracker, an electromagnetic calorimeter and an external veto for cosmic rays. The calorimeter plays an important role in providing excellent particle identification capabilities, a fast online trigger filter while aiding the track reconstruction capabilities. It consists of 1348 pure CsI crystals divided in two annular disks, each one readout by two large area Silicon Photomultipliers. A large scale prototype has been tested with an electron beam , demonstrating to largely satisfy the Mu2e requirements. At the moment of writing, the crystals and SiPMs production phase is halfway through the completion. An overview of the characterization tests is reported, together with a description of the final mechanical and electronical design.

Abstract

The domain structuring in concentrated mixtures of amphiphilic macromolecules with a different stiffness of backbone has been discovered and studied by means of molecular dynamics simulation. The macromolecules were composed of identical amphiphilic H-graft-P monomer units. In flexible macromolecules, the H-graft-P units are connected freely, whereas the stiff macromolecules have limitations imposed on torsion and bending angles and carry local helical structure. In solvent which is poor for the backbone, stiff macromolecules form filament clusters from few intertwined helical chains. The filaments can be aligned along each other sharing a common director or form a few liquid-crystalline domains oriented randomly with respect to each other. It was shown that increase of fraction of helical macromolecules leads to decrease of order parameter and its high variation over different samples due to the increase of length and polydispersity of persistent filaments.

Abstract

Formation of long-lived coloured forms of indoline spirocompounds (spirooxazines and spiropyrans) molecules under matrix immobilization in polar polymer of different chemical structure using supercritical fluid impregnation is studied. Some of such systems acquire additional optical characteristics besides colour – they become fluorophores. Mechanisms of observed changes in optical properties and long-term stability of the resulting coloured forms of indoline spirooxazine in polymers are discussed. Electronic absorption spectra of such coloured forms were recorded in supercritical carbon dioxide medium as well as on air. The results can be applied for creation of optical, biomedical and electronic devices and stable fluorescence composite coverings.

Abstract

A multi-scale molecular dynamics simulation was implied to study the formation of hypercrosslinked polystyrene networks at different rates of cross-linking. The rate of cross-linking reaction was controlled by wide-range variation of the probability of chemical bonding between the particles within the reaction distance on individual step of the simulation. The cross-linking was performed in the framework of the coarse-grained model, with the force fields derived from atomistic simulations. The macroscopic properties of network were studied using the atomistic samples restored from the coarse-grained configurations by a reverse mapping procedure. It was shown that the rate of cross-linking influences the structure of “synthesized” hypercrosslinked networks: Slowly cross-linked polymer networks have smaller total specific surface, lower average density, larger pores than those cross-linked at high rate.

Abstract

The most important task in the production of foam concrete is the selection of silica-containing components from both natural and technogenic raw materials, the use of which can not only reduce the consumption of the most energy-intensive and expensive component of foam concrete/Portland cement, but also allows to control the process of structure formation. The novelty of the paper is to identify the scientific patterns of the process control to foam concrete microstructure formation by using the system “Portland cement - opoka marl-fly ash” as a composite binder. The composite binders obtained by mechanochemical activation of Portland cement, opoka marl and fly ash were prepared as the novel compositions, based on which the concretes with improved behaviors are created. The physico mechanical characteristics of the concretes were researched by a series of tests including heat intensity of hydration, shrinkage, average density, and compressive strength, in addition to the durability characteristics (freeze-thaw resistance, vapor permeability) and thermal conductivity. The morphology and microstructure of the obtained cement pastes and concretes was studied by a complex of methods, including SEM images, XRD analysis and DTA analysis. For the first time, the scientific data on the properties of the composite binders and the foam concrete based on it were obtained. The nature of the influence of fly ash on the microstructure formation processes of the foam concrete mix for wall materials is revealed. The composite binders obtained by milling components have a compressive strength of up to 60 MPa with cement savings of up to 40%. Based on the composite binder, the foam concrete with a density of 500–700 kg/m3 with a compressive strength of up to 4.26 MPa were obtained.

Abstract

The coarse-grained model of polylactic acid (PLA) has been refined for applicability within an extended temperature range and used to investigate the mechanical and structural properties of uniaxially strained pure PLA and its blends with oligolactic acid (OLA). In the blends with higher OLA content of 40% segregation between OLA and PLA molecules was detected. It was shown that the elastic modulus and degree of ordering increase along with the strain rate. The values of the elastic modulus were found to be in quantitative agreement with experimental data. The coarse-grained approach can be used for simulation of PLA-based systems.

Abstract

The work is focused on the development of production methods of large scintillators based on lutetium-gadolinium oxyorthosilicate doped with cerium Lu2xGd2−2xSiO5:Ce (LGSO:Ce). Large LGSO:Ce crystals were grown by the Czochralski method, and a set of experimental samples for testing of scintillation characteristics was produced. Possibilities are discussed to use this scintillator in high energy physics experiments. In particular, an electromagnetic calorimeter to search for conversion of electrons into muons, which is forbidden in the Standard Model.

Abstract

The charge-exchange break-up of polarised deuterons d → p → { p p } s n , where the final { p p } s diproton system has a very low excitation energy and hence is mainly in the S 0 1 state, is a powerful tool to probe the spin-flip terms in the proton–neutron charge-exchange scattering. Recent measurements with the ANKE spectrometer at the COSY storage ring at 1.6, 1.8, and 2.27 GeV have extended these studies into the pion-production regime in order to investigate the mechanism for the excitation of the Δ ( 1232 ) isobar in the d → p → { p p } s X reaction. Values of the differential cross section and two deuteron tensor analysing powers, A x x and A y y , have been extracted as functions of the momentum transfer to the diproton or the invariant mass M X of the unobserved system X. The unpolarised cross section in the high M X region is well described in a model that includes only direct excitation of the Δ isobar through undistorted one pion exchange. However, the cross section is grossly underestimated for low M X , even when Δ excitation in the projectile deuteron is included in the calculation. Furthermore, direct Δ production through one pion exchange only reproduces the angular dependence of the difference between the two tensor analysing powers.

Abstract

We present a measurement of W boson polarization in top-quark decays in t{bar t} events with decays to dilepton final states using 5.1 fb{sup -1} integrated luminosity in p{bar p} collisions collected by the CDF II detector at the Tevatron. A simultaneous measurement of the fractions of longitudinal (f{sub 0}) and right-handed (f{sub +}) W bosons yields the results f{sub 0} = 0.71{sub -0.17}{sup +0.18}(stat) {+-} 0.06(syst) and f{sub +} = -0.07 {+-} 0.09(stat) {+-} 0.03(syst). Combining this measurement with our previous result based on single lepton final states, we obtain f{sub 0} = 0.84 {+-} 0.09(stat) {+-} 0.05(syst) and f{sub +} = -0.16 {+-} 0.05(stat) {+-} 0.04(syst). The results are consistent with standard model expectation.

Abstract

A search for a narrow Higgs boson resonance in the diphoton mass spectrum is presented based on data corresponding to 10 fb − 1 of integrated luminosity collected by the CDF experiment from proton–antiproton collisions at s = 1.96 TeV . To increase the sensitivity of the search, we employ a multivariate discriminant technique for the first time in this channel at CDF. No evidence of signal is observed, and upper limits are set on the cross section times branching ratio of the resonant state as a function of the Higgs boson mass. The limits are interpreted in the context of the standard model with an expected (observed) limit on the cross section times branching ratio of 9.9 (17.0) times the standard model prediction at the 95% credibility level for a Higgs boson mass of 125 GeV / c 2 . Moreover, a Higgs boson with suppressed couplings to fermions is excluded for masses below 114 GeV / c 2 at the 95% credibility level.
