Abstract

In this letter we show that most of the fluctuations in particle densities observed in relativistic heavy-ion collisions are consistent with stochastic emission, i.e., most of the correlations between produced particles are washed out due to the vast number of particles in the environment. We further explore the general trends by investigating different systems, energies and centrality cuts. Comparisons with the Fritiof model show that string fragmentation gives results similar to the data.

Abstract

In the present letter we discuss the general features of the multiplicity distributions in relativistic heavy ion collisions. It is shown that from simple statistical considerations it is possible to predict the dependence of the dispersions of multiplicity distributions on the average multiplicities in any given rapidty wwindow. The applicability of the negative binomial distribution to multiplicity distributions from collisions with heavy ions is discussed.

Abstract

The average multiplicities of singly charged relativistic particles in oxygen-induced interactions with a nuclear emulsion target are studied over the energy range 2.1–200 A GeV. A similar energy dependence as for proton-induced interactions is observed. Both the number of participating nucleons and the number of binary collisions are shown to be of importance for the particle production.

Abstract

The multiplicity distributions of low-energetic target-associated particles from 200 A GeV oxygen-induced interactions with emulsion nuclei are presented. The experimental distributions are compared with distributions obtained using the Ranft and Fritiof simulation codes. It is found that the intra-nuclear cascade plays an important role in ion-induced interactions, similar to what is the case for hadron-induced interactions.

Abstract

Glaciers are widely recognized as key indicators of climate change. Recent evidence suggests an acceleration of glacier mass loss in several key mountain regions. Glacier recession implies landscape changes in the glacial zone, the origin of new lakes and activation of natural disaster processes, catastrophic mudflows, ice avalanches, outburst floods, etc. The absence or inadequacy of such information results in financial and human losses. A more comprehensive evaluation of glacier changes is imperative to assess ice contributions to global sea level rise and the future of water resources from glacial basins. One of the urgent steps is a full inventory of all ice bodies and their changes. The first estimation of glacier state and glacier distribution on the territory of the former Soviet Union has been done in the USSR Glacier Inventory (UGI) published in 1965‐1982. The UGI is based on topographic maps and air photos and reflects the status of the glaciers in the 1940s‐1970s. There is information about 28 884 glaciers with an area of 7830.75 km 2 in the inventory. It covers 25 glacier systems in Northern Eurasia. In the 1980s the UGI has been transformed into digital form as a part of the World Glacier Inventory (WGI). Recent satellite data provide a unique opportunity to look again at these glaciers and to evaluate changes in glacier extent for the second part of the 20th century. About 15 000 glacier outlines for the Caucasus, Polar Urals, Pamir Alay, Tien Shan, Altai, Kamchatka and Russian Arctic have been derived from ASTER and Landsat imagery and can be used for glacier change evaluation. Results of the analysis indicate the steady trend in glacier shrinkage in all mountain regions for the second part of the 20th century. Glacier area loss for the studied regions varies from 13% (Tien Shan) to 22.3% (Polar Urals). The common driver, most likely, is an increase in summer air temperature. There is also a very large variability in the degree of individual glacier degradation, very much depending on the morphology and local meteorological conditions.

Abstract

Measurements have been made of inclusive 525 GeV [pi][sup [minus]] interactions in emulsion. The results are compared to proton-emulsion and lower energy pion-emulsion data. Average multiplicities of relativistic shower particles increase with increasing energy, although with a somewhat steeper slope above 60 GeV than at lower energies. The ratio [l angle][ital n][sub [ital s]][r angle][sub [ital p]]/[l angle][ital n][sub [ital s]][r angle][sub [pi]][similar to]1.1 over the energy range 60--525 GeV. The ratio of the dispersion in the multiplicity distribution to the average multiplicity is the same for proton and pion collisions in emulsion, and is independent of projectile energy. The shape of the shower particle multiplicity distribution does not vary significantly with energy, and KNO scaling appears to hold over the energy range 60--525 GeV. The shower particle pseudorapidity distributions are independent of the beam energy in the target and projectile fragmentation regions, and both the pseudorapidity and multiplicity distributions agree reasonably well with the FRITIOF model predictions for 525 GeV pions. The dependence of the shower particle multiplicity [l angle][ital n][sub [ital s]][r angle] on the number of heavy tracks [ital N][sub [ital h]] appraoches saturation as the total shower particle energy becomes a significant fraction of [radical][ital s]more » , and the pseudorapidity distributions shift toward smaller [l angle][eta][r angle] with increasing numbers of grey and black tracks at 525 GeV. Neither the average number [l angle][ital N][sub [ital h]][r angle] nor the multiplicity distributions of the heavily ionizing tracks vary significantly with energy, and the normalized angular distributions of grey and black tracks are independent of the type of projectile or projectile energy.« less

Abstract

The recent status of the EMU01 experiment where nuclear emulsions are used as both target/detector material for horizontally exposed stacks and as detector for vertically exposed chamber plates is discussed. An investigation of the behaviour in the number of produced particles per participating nucleon reveal weak nonlinear effects for the most central collisions. Intermittency index can be obtained from the density distributions for S+Au and S+Ag interactions which corresponds to fractal dimensions somewhat smaller than unity.

Abstract

S+Au interactions at 200{ital A} GeV were observed using emulsion chambers, permitting measurement of pseudorapidities in the central region with precision {similar to}0.01 unit. Scaled-factorial-moment analyses are extended to bin sizes smaller than those accessible to other fixed-target experimental techniques. For a sample of 151 central collisions, moments are calculated using both horizontal'' and vertical'' analysis techniques. While the moments are found to rise (in a log-log plot) with decreasing pseudorapidity bin size {delta}{eta}, their slopes roll off to approximately zero for {delta}{eta}{lt}0.1.

Abstract

The pseudo-rapidity density distributions of shower particles (n s ) are measured in central inelastic S + Au and S + Ag,Br inter-actions. The extracted maximum energy densities, while being higher for Au than for Ag.Br interactions, were found to be similar to those obtained for oxygen emulsion interactions. The correlation between rapidity density and shower particle multiplicity shows a small deviation from the Lund Model Fritiof for the highest energy densities in S + Au interactions, whereas the bulk of the data yields satisfactory agreement.

Abstract

The basic experimental characteristics of incoherent interactions of 400 GeV protons on emulsion nuclei, such as the multiplicity of charged secondaries, one-particle distributions and two-particle correlations, are reported and discussed in details. They are compared with the results of other experiments on hadron-nucleus interactions at lower energies. We have shown from both the quantitative and qualitative comparison of the data presented with predictions of various model approaches to nuclear production, that most of them cannot explain the complete set of experimental observations. An analysis of the experimental data presented gives strong support to the idea that the production mechanism in high-energy hadron-nucleus interactions has two or multi-component character.

Abstract

The multiplicity distributions of shower particles (ns) are measured in inclusive inelastic oxygen emulsion interactions. Scaling is observed in the normalized variable ns/〈ns〉 for 14.6, 60 and 200 AGeV. The dependence of 〈ns〉 on the charge flow in the forward direction (QZD) and the distribution of the number of participating projectile protons is examined. The normalized multiplicities as a function of QZD seem also to be independent of incident energies. A comparison with the Lund model Fritiof yields satisfactory agreement.

Abstract

We report on an experiment in which emulsion chambers were exposed to a beam of 200 A GeV 16 O at the CERN SPS. Pseudo-rapidity distributions are measured with high precision. Pseudo-rapidity densities of 140 particles per unit rapidity corresponding to an energy density of about 3 GeV/fm3 are observed. Pseudo-rapidity density distributions and fluctuations are found to satisfactorily agree with the Lund Monte Carlo model Fritiof, although new and unknown sources for fluctuations might still be present.

Abstract

The interaction of 800-GeV protons in nuclear emulsion has been investigated. The multiplicities and angular distributions of charged particles emitted by both the projectile and the target nucleus have been measured for 1718 inelastic events and are compared with the data obtained in proton-emulsion collisions at 67, 200, and 400 GeV. The target excitation is found to be independent of energy while the production of secondary particles continues to increase with incident proton energy.

Abstract

Data on multiparticle production on emulsion nuclei in the range 50–400 GeV/c have been analyzed in the framework of multiple scattering model developed by Capella and Krzywicki. It is shown that under some reasonable assumptions multiple scattering type models qualitatively reproduce multiplicity distributions of relativistic charged particles, one-particle spectra and two-particle inclusive correlations.

In the study of interactions of 60 GeV/c π− mesons in nuclear emulsion some peculiarities of the prong-number distribution and the angular distribution of secondaries have been observed. They are interpreted in terms of the coherent production of three and five pions on emulsion nuclei. The cross section for these reactions increases with the increasing energy.

Abstract

An investigation of the energy dependence of grey prong producing particles in 16 O+ emulsion interactions at energies from 2.1 to 200 A GeV is reported. Many of the features of these particles, known from hadron-induced interactions, are shown to be of importance also in heavy-ion interactions, i.e. multiplicity and angular distributions as well as the impact parameter dependence are energy independent. Furthermore the angular distribution seems to be independent of the projectile and target masses as well as centrality of the interactions. Both the Fritiof and Ranft models fail to reproduce this general angular shape.

Abstract

Here we present results on charged hadron production in an experiment using tracking detectors with the highest possible spatial resolution: emulsion chambers. A sample of the most central collisions will be compared to the predictions of the Lund Model, which does an accurate job of representing conventional (non−quark−gluon plasma) physics in nuclear reactions. We can use the high resolution of our detectors to examine spatial correlations in several ways. In particular, the radial size of the particle formation region can be estimated using pion interferometry techniques. (AIP)

Pseudorapidity distributions of relativistic singly charged particles in oxygen-induced emulsion interactions at 14.6, 60, and 200 GeV/nucleon are studied. Limiting fragmentation behavior is observed in both the target and projectile fragmentation regions for a central as well as for a minimum-bias sample. Comparisons with the fritiof model reveal that the picture of fragmenting strings successfully describes the observed data.

Abstract

Fluctuations in particle densities of non-statistical origin are studied in central 16 O+Ag(Br) and 32 S+Au interactions at 200 A GeV. Non-statistical fluctuations in the 32 S-induced interactions seem to enhance the local particle densities, and suggest the presence of intermittancy. The fluctuations are found to be accompanied by a clustering tendency also in the azimuthal plane. A new method for the study of azimuthal correlations is proposed.

Abstract

Angular distributions of charged particles produced in 16O and 32S collisions with nuclear track emulsion were studied at momenta 4.5 and 200 A GeV/c. Comparison with the angular distributions of charged particles produced in proton-nucleus collisions at the same momentum allows to draw the conclusion, that the angular distributions in nucleus-nucleus collisions can be seen as superposition of the angular distributions in nucleon-nucleus collisions taken at the same impact parameter bNA, that is mean impact parameter between the participating projectile nucleons and the center of the target nucleus

Abstract

Angular distributions of projectile-associated He fragments from Pb induced reactions on stationary Pb target at 158 A GeV/c incident momentum are reported. The precision of the angular measurements was about ±0.01 mrad. Two emission components are appearing in the projected angular spectra of the He particles, one representing fragmentation at Fermi momentum scale, while the other one exhibits large transverse momentum transfer. By scaling with the incident momentum the angular spectra of He particles are compared with earlier reported measurements of Au on Au interactions at 11.6 A GeV/c. The p T spectrum of the He particles appears the same for the two cases.

Abstract

This article discusses the possibility of radical surgical treatment of vulvar cancer depending on the presence of concomitant diseases. It covers positive and negative aspects of various surgical techniques with a reconstructive component. The issue of closing the wound defect after vulvectomy and performing reconstructive surgery has always been controversial; it reduced the number of indications for such surgeries and often caused refusal from it.

Abstract

Soporific substances of the third generation - Z-preparations: Zaleplon (Andante), Zopiclone (Imovane) and Zolpidem (Ivadal) - are widely used in medicine for the treatment of insomnia. Despite a number of advantages over of barbiturate derivatives and 1,4-benzodiazepine, the identified preparations are toxic. Poisoning incidents, including fatalities, are described. To diagnose intoxications by these medicines and other purposes (for monitoring the concentration of these medicines in the blood, studying pharmacokinetics, evaluating drug interactions, optimizing treatment control), the development of methods for defining Z-preparations in biological objects becomes important, that is currently developed insufficient. Therefore, the purpose of this work is to study and analyze the specialized literature on the chemical, physico-chemical, pharmacological properties, methods of analysis of investigated substances, methods of extraction, purification, methods of identification and quantification while studying the biological objects.

Abstract

In the given article, the technique is described and the experimental data for identifying Zaleplon, Zolpidem and Zopiclone (Z-preparations) by method of UV - spectrophotometry isolated from liver tissue are determined. The isolation of Z-preparations was carried out with one of amphiphilic solvents - acetone; purification of impurities - by H-hexane extraction from an acidic medium; TLC was used for additional purification. The Z-preparations were identified by the sequential application of TLC screening and UV-spectrophotometry. The UV-spectrophotometric method was used to determine the quantitative content of the analysis substances. The parameters and validation characteristics of the method were determined, both in the study of native Z-preparations and those isolated from biological objects (linearity, specificity, robustness, and detection limits).

Abstract

Background. The problem of perfectionism is fairly actual in the psychological science as high levels of this characteristic may become the reason of anxiety disorders and even depression. Recent research in the field proves that perfectionism may serve as a factor increasing the risk of suicidal bevavior, there are also data showing it provokes the development of children’s depression. The objective of this study is to find out the role of parental upringing in the development of perfectionism and analyze the relation between particular parental styles and perfectionism as well as the basic features of this relation. Method. The relationship between children perfectionism development and maternal rearing styles was learned with the help of correlation analysis (r-Pearson criterion) and strategy of finding differences (U-Mann-Whitney criterion). The following psycho-diagnostic tools were used: Multidimensional Scale of Perfectionism by P.L. Hewitt & G.L. Flett (adapted by I. Hrachova) and Multidimensional Scale of Perfectionism by R. Frost (adapted by N.G. Haranyan); the Questionnaire “Adolescents about Parents” by L.I. Vasserman, I.A. Gor’kovaya and Y.Y. Romitsyna (the adaptation of ADOR by E. Matejcek & P. Rican, 1983); the authors’ Questionnaire. Sample: 35 adolescents (19 males and 16 females), students of 9-11 classes. Results. Mother’s positive interest to a child (in children’s perception) is related with such components of perfectionism as parents’ expectations (r = -.447 at p
