О ДОПОЛНИТЕЛЬНОЙ ПРОФЕССИОНАЛЬНОЙ ПОДГОТОВКЕ ПО ЭКСПЕРТНЫМ СПЕЦИАЛЬНОСТЯМ В НАЦИОНАЛЬНОМ БЮРО ЭКСПЕРТИЗ

The paper is devoted to the Regulation on Additional Professional Training in Expert Specialties developed by the National Bureau of Expertises of the Republic of Armenia and realized in practice. It’s noted that the unified approaches, set forth in the Regulation, to the retraining of forensic experts ofdifferent specializations within the framework of individual short- and medium-term courses make it possible to provide the required level of professional training with the subsequent certification of the applicant for the right to independently perform a forensic examination. The peculiarities of the current model of additional professional education are described, including testing the basic knowledge of the applicant at the first stage, and in case ofsatisfactory evaluation, after an oral interview, training on the developed individual program consisting of theoretical and practical parts. Upon completion of the training program, the accompanying materials on the applicant’s candidature are submitted to the meeting of the Qualification Commission established by the National Bureau of Expertises, which gives the right to the applicant to carry out independent forensic examination in one or another expert specialty (since 2005 in this manner more than 300 applicants it’s prepared). The paper also emphasizes that the programs of additional professional training are periodically revised, supplemented with introducing new relevant training modules into the programs. In particular, the paper contains links to the introduction of modules such as time management and stress management into the educational process. The paper also highlights the accumulated experience allowing to provide a qualitative level ofexperts continuous training of the National Bureau of Expertises, particularly, on definition of the criteria necessaryfor granting independence to the expert, terms and duration of the probation period of his activity, criteria for evaluating this activity.Наведено положення про додаткову професійну підготовку за експертними спеціальностями, розроблене в Національному бюро експертиз Республіки Вірменія та реалізуєме на практиці.

Effect of transplantation of allogeneic multipotent mesenchymal bone marrow stromal cells on regeneration of liver after extended hepatectomy (experimental study)

© 2018 Human Stem Cell Institute. All rights reserved. Multipotent mesenchymal stromal cells can be a drug for treatment of acute liver failure. The purpose of this study was to assess the effect of multipotent mesenchymal stromal cells on the proliferative, mitotic activity of hepatocytes and morphometric criteria for the regeneration of liver parenchyma after 68 % partial hepatectomy in rats. The number of mitosis, PCNA positive cells, diameter of nucleus of hepatocytes, size of hepatocytes, nuclear-cytoplasmic ratio (NCR), the area of hepatic lobules were evaluated on 1, 2, 4, 14 days after surgery. The results of the study showed that intravenous administration of allogeneic mesenchymal multipotent stromal cells from bone marrow after extended hepatectomy increase the number of proliferating hepatocytes (PCNA positive cells), but does not affect the number of mitoses, the diameter of the nucleus, the area of hepatocytes, NCR and hepatic lobules. Probably, at this time, regeneration proceeds primarily through an intracellular mechanism

Regularities of the Formation of the City Pedestrian Environment

The article critically examines the design and construction of pedestrian areas, considering the specifics of transport services in the largest cities of Russia, cultural heritage and scale of modern mobility of the population. It also emphasizes the need to solve the problem of formation of pedestrian streets, adjusting the relevance of the proposed small urban design, without forgetting the main purpose of the street - to ensure the movement of pedestrians. At the same time, it is asserted that the content of the street is a showcase of the actual functional purpose of objects that are placed in a certain place, often with along history, and not a contrived decoration, often out of place borrowed from foreign practice. In order to identify public opinion about thelatest trends in the organization of pedestrian traffic, a preliminary survey of residents, mainly with children or grandchildren, was conducted, and it showed the failure of the idea of carrying out yard functions on the street for our practice. At the same time, the return of the experience of the XII-XIII centuries, when vehicles were not allowed into the yards and two exits from residential buildings were created: one "front" and the other "black", overlooking the economic yard, helped to solve the modern problem of separation of space for pedestrians and transport

Does the Constitution Provide More Ballot Access Protection for Presidential Elections Than for U.S. House Elections?

Both the U.S. Constitution and The Federalist Papers suggest that voters ought to have more freedom to vote for the candidate of their choice for the U.S. House of Representatives than they do for the President or the U.S. Senate. Yet, strangely, for the last thirty-three years, the U.S. Supreme Court and lower courts have ruled that the Constitution gives voters more freedom to vote for the candidate of their choice in presidential elections than in congressional elections. Also, state legislatures, which have been writing ballot access laws since 1888, have passed laws that make it easier for minor-party and independent candidates to get on the ballot for President than for the U.S. House. As a result, voters in virtually every state invariably have far more choices on their general election ballots for the President than they do for the House. This Article argues that the right of a voter to vote for someone other than a Democrat or a Republican for the House is just as important as a voter’s right to do so for President, and that courts should grant more ballot access protection to minor-party and independent candidates for the House

A comparison of forward and backward pp pair knockout in 3He(e,e'pp)n

Measuring nucleon-nucleon Short Range Correlations (SRC) has been a goal of the nuclear physics community for many years. They are an important part of the nuclear wavefunction, accounting for almost all of the high-momentum strength. They are closely related to the EMC effect. While their overall probability has been measured, measuring their momentum distributions is more difficult. In order to determine the best configuration for studying SRC momentum distributions, we measured the $^3$He$(e,e'pp)n$ reaction, looking at events with high momentum protons ($p_p > 0.35$ GeV/c) and a low momentum neutron ($p_n< 0.2$ GeV/c). We examined two angular configurations: either both protons emitted forward or one proton emitted forward and one backward (with respect to the momentum transfer, $\vec q$). The measured relative momentum distribution of the events with one forward and one backward proton was much closer to the calculated initial-state $pp$ relative momentum distribution, indicating that this is the preferred configuration for measuring SRC.Comment: 8 pages, 9 figures, submitted to Phys Rev C.

БИК-спектроскопия с применением хемометрических алгоритмов при проведении судебно-экспертных исследований древесины

The article addresses practical aspects of applying the spectroscopy in the near infrared region method when conducting forensic examinations of wood. Based on the obtained results, it has been concluded that the NIR spectra can be used as an informative indicator to determine the species of woody plants, as well as to track the origin of timber and to detect the facts of illegal logging. The authors demonstrate the possibility of interpreting the obtained spectral data using formal independent class analogy modeling and discriminant analysis of projections onto latent structures. They have also built stable workable classification models to differentiate Dipteryx odorata (Cumaru) and Dipteryx panamensis (Cumarurana), as well as common hornbeam (Carpinus betulus) of various geographical origin.В статье рассмотрены практические аспекты использования метода спектроскопии в ближней инфракрасной области при проведении судебно-экспертных исследований древесины.

Transverse Polarization of Σ+(1189)\Sigma^{+}(1189) in Photoproduction on a Hydrogen Target in CLAS

Experimental results on the $\Sigma^+(1189)$ hyperon transverse polarization in photoproduction on a hydrogen target using the CLAS detector at Jefferson laboratory are presented. The $\Sigma^+(1189)$ was reconstructed in the exclusive reaction $\gamma+p\rightarrow K^{0}_{S} + \Sigma^+(1189)$ via the $\Sigma^{+} \to p \pi^{0}$ decay mode. The $K^{0}_S$ was reconstructed in the invariant mass of two oppositely charged pions with the $\pi^0$ identified in the missing mass of the detected $p\pi^+\pi^-$ final state. Experimental data were collected in the photon energy range $E_{\gamma}$ = 1.0-3.5 GeV ($\sqrt{s}$ range 1.66-2.73 GeV). We observe a large negative polarization of up to 95%. As the mechanism of transverse polarization of hyperons produced in unpolarized photoproduction experiments is still not well understood, these results will help to distinguish between different theoretical models on hyperon production and provide valuable information for the searches of missing baryon resonances.Comment: pages 1

The Heavy Photon Search test detector

The Heavy Photon Search (HPS), an experiment to search for a hidden sector photon in fixed target electroproduction, is preparing for installation at the Thomas Jefferson National Accelerator Facility (JLab) in the Fall of 2014. As the first stage of this project, the HPS Test Run apparatus was constructed and operated in 2012 to demonstrate the experiment׳s technical feasibility and to confirm that the trigger rates and occupancies are as expected. This paper describes the HPS Test Run apparatus and readout electronics and its performance. In this setting, a heavy photon can be identified as a narrow peak in the e+e− invariant mass spectrum above the trident background or as a narrow invariant mass peak with a decay vertex displaced from the production target, so charged particle tracking and vertexing are needed for its detection. In the HPS Test Run, charged particles are measured with a compact forward silicon microstrip tracker inside a dipole magnet. Electromagnetic showers are detected in a PbW04 crystal calorimeter situated behind the magnet, and are used to trigger the experiment and identify electrons and positrons. Both detectors are placed close to the beam line and split top-bottom. This arrangement provides sensitivity to low-mass heavy photons, allows clear passage of the unscattered beam, and avoids the spray of degraded electrons coming from the target. The discrimination between prompt and displaced e+e− pairs requires the first layer of silicon sensors be placed only 10 cm downstream of the target. The expected signal is small, and the trident background huge, so the experiment requires very large statistics. Accordingly, the HPS Test Run utilizes high-rate readout and data acquisition electronics and a fast trigger to exploit the essentially 100% duty cycle of the CEBAF accelerator at JLab

Cross sections for the γp→K*+Λ and γp→K*+Σ0 reactions measured at CLAS

The first high-statistics cross sections for the reactions γp→K*+Λ and γp→K*+Σ0 were measured using the CLAS detector at photon energies between threshold and 3.9 GeV at the Thomas Jefferson National Accelerator Facility. Differential cross sections are presented over the full range of the center-of-mass angles, and then fitted to Legendre polynomials to extract the total cross section. Results for the K*+Λ final state are compared with two different calculations in an isobar and a Regge model, respectively. Theoretical calculations significantly underestimate the K*+Λ total cross sections between 2.1 and 2.6 GeV, but are in better agreement with present data at higher photon energies

Induced polarization of {\Lambda}(1116) in kaon electroproduction

We have measured the induced polarization of the ${\Lambda}(1116)$ in the reaction $ep\rightarrow e'K^+{\Lambda}$, detecting the scattered $e'$ and $K^+$ in the final state along with the proton from the decay $\Lambda\rightarrow p\pi^-$.The present study used the CEBAF Large Acceptance Spectrometer (CLAS), which allowed for a large kinematic acceptance in invariant energy $W$ ($1.6\leq W \leq 2.7$ GeV) and covered the full range of the kaon production angle at an average momentum transfer $Q^2=1.90$ GeV$^2$.In this experiment a 5.50 GeV electron beam was incident upon an unpolarized liquid-hydrogen target. We have mapped out the $W$ and kaon production angle dependencies of the induced polarization and found striking differences from photoproduction data over most of the kinematic range studied. However, we also found that the induced polarization is essentially $Q^2$ independent in our kinematic domain, suggesting that somewhere below the $Q^2$ covered here there must be a strong $Q^2$ dependence. Along with previously published photo- and electroproduction cross sections and polarization observables, these data are needed for the development of models, such as effective field theories, and as input to coupled-channel analyses that can provide evidence of previously unobserved $s$-channel resonances.Comment: 13 figure
