2. Visual snow syndrome

Author: Silvia Cherninkova and T. Angelov
Subjects: Visual snow syndrome, клинични случаи, Neurology. Diseases of the nervous system, RC346-429
Abstract: Visual snow syndrome (VSS) е рядко клинично състояние, характеризиращо се с персистиращи положителни зрителни феномени в двете очи – множествени трептящи малки точки и петънца едновременно пред двете очи, перманентни, ангажиращи цялото зрително поле. VSS се наблюдава предимно в млада възраст, с начало на оплакванията най-често в трета декада, като по-често е засегнат женският пол. Патофизиологията на синдрома не е изяснена. Клинично, неврологичният и офталмологичният статус, както и образните изследвания на главен мозък са в границите на нормата. В настоящата публикация, представяме 5 пациенти (3 мъже и 2 жени, средна възраст при изследването 23,8 ± 7,08 години) с поставена клинична диагноза VSS. Средната възраст на начало на оплакванията им от поява на „светещи и трепкащи петънца” пред цялото зрително поле, едновременно и в двете очи, перманентни, е 17,0 ± 8,09 години. При всички пациенти невроофталмологичният статус, включващ опреде ляне на зрителна острота с корекция, биомикроскопия на преден очен сегмент, тонометрия, офталмоскопия, оценка на окуломоториката, по преценка оптично-кохерентна томография и др. е в граници на нормата. Магнитно-резонансна томография на главен мозък, проведена при всички болни, както и електроенцефалографското изследване показват нормална находка. Състоянието на болните се проследява в динамика.

3. Automated generation of test units for diagnosis and development of cognitive skills

Author: T. Angelov, V. Sivakova, and G. Totkov
Subjects: cognitive skills, cognitive language assessment tasks, cognitive task model, automated test unit generation, Science (General), Q1-390
Abstract: The paper presents the architecture of a web-based system for automated generation of test units for diagnostics and development of cognitive skills. The system supports a database (DB) containing information objects of different type (text, images), including metadata used in the generation process. The database is updated through queries to external information sources (to supply the objects themselves) and with next addition of attributes. For example, an image can be accompanied by a textual description and metadata (as part of an e-learning process), a Bulgarian lexema - with automatically generated phonetic transcription and syllabicate, and so on. The supported and updated specific image metadata system (including color, size, purpose, etc.) and for lexams (composite sounds, syllables, etc.) provides an opportunity to generate test units for diagnosis and cognitive development. The selection of objects from DB suitable for insertion in a test unit of a certain type (for example, to distinguish objects with different characteristics) is performed by a query to the database for extraction of objects according to the value of the accompanying metadata.

4. Targeted Screening of the C9orf72 Gene in Bulgarian Amyotrophic Lateral Sclerosis Patients

Author: S. Ormandzhiev, T. Todorov, T. Angelov, T. Chamova, V. Mitev, A. Todorova, and I. Tournev
Abstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease, characterized by progressive degeneration of the upper and lower motor neurons, leading to muscle weakness, hypotrophy, swallowing and respiratory failure. The cause of ALS is not yet fully elucidated, but there are 35 associated genes and 2 gene loci with an unidentified gene. The most common are C9orf72, SOD1, TARDBP and FUS found in approximately 10% of patients. Variants in the C9orf72 gene are the main cause of fALS – 25-40% of cases (and a small percentage of sALS). The goal of the present study was to evaluate the significance of the C9orf72 hexanucleotide repeat expansion in Bulgarian patients with ALS, through the means of in house and triplet repeat-primed PCR assay (TP-PCR). From 171 patients diagnosed with ALS and included in the current study, we have identified the repeat expansion with more than 145 GGGGCC repeats in 7 (4,1%). Short expansions or borderline values (24 to 30 repeats) were not detected. Due to absence of sufficient data, we have established an ALS-focused research for the association of the C9orf72 gene in clinically well-characterized Bulgarian ALS patients. Published data show variable percentage ratios for genetically verified cases (4-40%), which is mainly due to small sample counts and sALS-fALS ratios. Our patients’ group also contains sALS and fALS cases, which explains the low percentage of genetic verification. The obtained results enrich the worldwide database and shed light onto genetically characterized Bulgarian ALS patients. Affected patients and their families can receive adequate medical-genetic consultation and prenatal diagnostic testing.

Abstract: Neuropsychiatric disorders, including depression contribute significantly to global disability and possess high social and health burden. Management is dominated by pharmacotherapy and psychotherapy; nevertheless, such treatments prevent or treat less than half of the patients, suggesting that alternative approaches are required. Emerging data suggest that diet may be an adjustable risk factor for psychiatric disorders. Caloric restriction (CR) possesses protective effects in almost all organs including the brain. However, the precise molecular pathways of these effects remain uncertain. In this review, we will discuss the putative neurobiological mechanisms of CR on the brain. The article will address also the molecular basis of the antidepressant effects of CR, primarily including ghrelin signaling, CREB neurotropic effects and ketone bodies production. Then we will highlight the probable effect of CR on the neuroinflammation, which emerges as a key pathogenetic factor for the majority of neuropsychiatric disorders. Finally, we discuss the so called caloric restriction mimetics, compounds that reproduce properties of CR. Further research will be required to verify the safety and efficacy of CR before a general approval can be proposed to introduce it and its mimetics in clinical practice for the treatment of neuropsychiatric disorders.

Abstract: Helicobacter pylori (H. pylori) infection is spread worldwide and affects at least half of the world's population. Infected people are at increased risk of several diseases' development, including gastric adenocarcinoma. The aim of this study was to screen patients with dyspeptic symptoms for H. pylori infection and assess Clarithromycin resistance prevalence among the infected patients.Screening for H. pylori infection was performed in all patients using molecular test based on Real-Time Polymerase Chain Reaction (RT-PCR) in feces after RNA-DNA extraction. Stool samples from all participants were collected 1 to 3 days after patients' hospitalization. The positive results were furthermore assessed for confirmation by breath test and stool antigen test. By point mutations detection in 23S rRNA gene was possible to detect Clarithromycin resistance. Statistical analysis was performed via SPSS 22.0 (IBM Corp., Armonk, NY, USA).This study enrolled 50 patients (18 males) at mean age 46.46±15.10 years. Using molecular test based on RT-PCR in feces we identified H. pylori infection in 24 patients (48.00%). Clarithromycin resistance was observed in 7 of them (29.17%). None of those patients was eradicated before. There was no significant difference by age and gender between infected and non-infected patients. Gastrointestinal symptoms were more often reported in infected patients (p0.05). The molecular test showed 85.71% sensitivity and 100% specificity, with a diagnostic accuracy of 92.00%.H. pylori screening by molecular test based on RT-PCR in feces might be beneficial as the test's accuracy is high and include Clarithromycin resistance assessment, which could improve the outcome of eradication therapy.

Abstract: Fast and reliable detection of patients with severe and heterogeneous illnesses is a major goal of precision medicine1,2. Patients with leukaemia can be identified using machine learning on the basis of their blood transcriptomes3. However, there is an increasing divide between what is technically possible and what is allowed, because of privacy legislation4,5. Here, to facilitate the integration of any medical data from any data owner worldwide without violating privacy laws, we introduce Swarm Learning—a decentralized machine-learning approach that unites edge computing, blockchain-based peer-to-peer networking and coordination while maintaining confidentiality without the need for a central coordinator, thereby going beyond federated learning. To illustrate the feasibility of using Swarm Learning to develop disease classifiers using distributed data, we chose four use cases of heterogeneous diseases (COVID-19, tuberculosis, leukaemia and lung pathologies). With more than 16,400 blood transcriptomes derived from 127 clinical studies with non-uniform distributions of cases and controls and substantial study biases, as well as more than 95,000 chest X-ray images, we show that Swarm Learning classifiers outperform those developed at individual sites. In addition, Swarm Learning completely fulfils local confidentiality regulations by design. We believe that this approach will notably accelerate the introduction of precision medicine. © 2021, The Author(s).

Subjects: bio-eco nomic models, economic weights, production and functional traits, dairy cattle, beef cattle, Agriculture
Abstract: Abstract. Bio-economic models for deriving economic weights in livestock have a significant development in recent years providing integrated assessment of biological and economic parameters of production systems and possibilities for achieving economic sustainability through inclusion in the selection index. Economic weights (EW) of traits have been calculated for different species of farm animals in the years. However, this review focuses on large ruminant aiming to summarize studies on calculation of economic values for dairy, beef and dual-purpose cattle. A method of research selection was used according to the productive direction (for milk, meat and dual-purpose), as well as according to the studied traits. In conclusion, it could be summarized that with regard to breeding objectives, economic weights of breeding traits need to be recalculated at certain time-periods and redefined in order to be relevant to the current market situations. Recently, there has been a tendency for functional traits to have an increasing economic influence and some of them should be included in the breeding goal. Moreover, the increased interest among customers in animal welfare and quality of dairy farm products will probably lead to the incorporation of health traits as clinical mastitis incidence and somatic cells score in the breeding objective. It is possible as well the relative importance of feed efficiency traits to increase in the future due to increasing requirements to mitigate the environmental impact of production systems.

Abstract: An HPLC method is applied for determination of the pKa values and lipophilicity parameter of the most useful preservatives in drugs oral solution formulations at different pH ranges. The same method is used for investigation on the lipophilicity of these compounds. The pKa and lipophilicity parameter values are the most important parameters characterizing the processes of penetration of the preservatives through the cellular membrane at different conditions. The higher lipophilicity contributes to better interaction of the preservatives with the membrane of undesirable microorganisms and assures their biological action.

Abstract: We present a study of the global event shape variables thrust and heavy jet mass, of energy-energy correlations and of jet multiplicities based on 250 000 hadronic Z 0 decays. The data are compared to new QCD calculations including resummation of leading and next-to-leading logarithms to all orders. We determine the strong coupling constant α s (91.2 GeV) = 0.125±0.003 (exp) ± 0.008 (theor). The first error is the experimental uncertainty. The second error is due to hadronization uncertainties and approximations in the calculations of the higher order corrections.

Abstract: Abstract. The aim of the present study was to evaluate allele frequencies and genotypes of kappa casein (CSN3) and their association with milk quality and coagulation properties in Brown cattle. Milk proteins’ polymorphism was found out in 155 tissue samples from cows reared at 4 farms. The analysis of milk composition was done in the lab of the Agriculture Institute – Stara Zagora on Lactoscan ultrasound milk analyzer, whereas coagulation properties of individual milk samples were evaluated on a Computerized Renneting Metter – Polo Trade, Italy. Milk samples were obtained by milk meters. The milk was analysed within 3 hours after sample collection. Naturen Plus 215/0.8L chymosin was used, with milk coagulation activity of 215 IMCU/ml. During the study, the following parameters were studied: milk fat and protein contents (%), rennet coagulation time (RCT, min), curd firmness (а30, mm) and curd firming time (k20, min). Kappa casein (CSN3) is characterised by five genotypes – АА, АВ, ВВ, АН and ВН, the frequency of which varied within various ranges. The milk of cows with genotype AB was characterized by the highest content of fat and protein: 4.85% and 5.00%, respectively. The milk of heterozygous cows from genotype AB demonstrated the longest rennet coagulation time – 18.04 min. The animals carrying the H allele produced milk with the highest curd firmness – 37.00 mm.

Abstract: We have measured the partial widths of the Z 0 into lepton pairs, and the forward-backward charge asymmetry for the process e + e − → μ + μ − using the L3 detector at LEP. We obtain an average Γ ll of 83.0±2.1±1.1 MeV.From this result and the asymmetry measurement, we extract the values of the vector and axial vector couplings of the Z 0 to leptons: g rmv =−0.066 −0.027 +0.046 and g rmA = −0.495 −0.007 +0.007 .

Abstract: An isothermal, steady‐state, hot‐strip rolling problem for rigid‐plastic, strain rate sensitive and incompressible materials with coulomb‐siebel friction contact conditions is considered. The corresponding penalty variational statement is given and a convergent finite element ‐ secant‐modulus method is presented. Two‐dimensional example problems are solved and comparisons with the available experimental and numerical results are made. The influence of the friction coefficient on the contact velocities, stresses and equivalent strain rates is illustrated.

Abstract: Abstract. The objective of this experiment was to investigate the effects of liquid organic mineral complex (MultiMix®) on the milk yield, composition and cheesemaking capacity of milk in dairy cows. Thirty Holstein cows (8 primiparous and 22 multiparous) were used in a randomized complete block design experiment with 15 cows per treatment. Feeding was ad libitum targeting 5% refusals. Milk yield data and samples for fat, true protein, solids not fat (SNF), lactose content and parameters characterizing the milk’s coagulation properties were collected throughout the experiment. Data suggested that MultiMix® administered through the cows’ drinking water had a positive effect on the milk productivity with a high degree of significance (p

Abstract: We search for neutral heavy leptons that are isosinglets under the standard SU(2)L gauge group. Such neutral heavy leptons are expected in many extensions of the standard model. Three types of heavy leptons Ne, N(mu), N(tau) associated with the three neutrino types nu(e), nu(mu), nu(tau) have been directly searched for and no evidence for a signal has been found. We set the limit Br(Z0 --> nu(l)N(l)) < 3 x 10(-5) at the 95% CL for the mass range from 3 GeV up to m(Z).

Abstract: We have measured the forward-backward asymmetry in e + e − → b b and e + e − → c c processes using hadronic events containing muons or electrons. The data sample corresponds to 4100000 hadronic decays of the Z0. From a fit to the single lepton and dilepton p and pT spectra, we determine A b b =0.086±0.015±0.007 and A c c =0.083±0.038±0.027 at the effective center-of-mass energy √s=91.24 GeV. These measurements yield a value of the electroweak mixing angle sin 2 θ w =0.2336±0.0029 .

Abstract: We have measured the total and differential cross sections of the reaction e+e− → γγ(γ) at center-of-mass energies around 91 GeV, with an integrated luminosity of 14.2 pb−1. The results are in good agreement with QED predictions. We set lower limits, at 95% confidence level, on the QED cutoff parameters of Λ+ > 139 GeV, Λ− > 108 GeV and on the mass of an excited electron of m e∗ > 127 GeV . We searched for Z0 rare decays with photonic signitures in the final state. Upper limits, at 95% confidence level, for branching ratio of Z0 decaying into π0γ/γγ, νγ and γγγ are 1.2 × 10−4, 1.8 × 10−4, 3.3 × 10−5 respectively.

Abstract: A more precise determination of the B°-B ° mixing parameter in Z ° decays based on a fourfold increase in statistics has been made using the 1990 and t99t L3 data. The analysis of the dilepton events, rnuons and electrons, gives: Za = 0.121 + 0.017 (stat) :t: 0.006 (sys). Using the value Of Xd measured at the "f(4S) we derive the following limit for Zs: Zs > 0.16 (90% CL)., Facultad de Ciencias Exactas

Abstract: We present a study of the inclusive production of neutral pions and charged particles from 112 000 hadronic Z 0 decays. The measured inclusive momentum distributions can be reproduced by parton shower Monte Carlo programs and also by an analytical QCD calculation. Comparing our results to e + e − data between √ s = 9 and 91 GeV, we findfind that the evolution of the spectra with center of mass energy is consistent with the QCD predictions.

Abstract: From 2540 Z0 → τ+τ− events, we determine the inclusive decay branching fractions of the τ-lepton into one and three charged particles to be 0.856 ± 0.006 (stat.) ± 0.003 (syst.) and 0.144 ± 0.006 (stat.) ± 0.003 (syst.), respectively. The leptonic branching fractions are measured to be 0.175 ± 0.008 (stat.) ± 0.005 (syst.) for τ → μνμντ and 0.177 ± 0.007 (stat.) ± 0.006 (syst.) for τ → eνeντ. We determined the τ lifetime both from three-prong decays using the decay length and from one-prong decays using the impact parameter. The results from the two independent methods agree and yield a combined value of [0.309 ± 0.023 (stat.) ± 0.030 (syst.)] × 10−12s.

Abstract: We have observed B0-B0 mixing in Z0→bb decays using hadronic events containing dileptons. The data sample corresponds to 118 200 hadron events at √s≈Mz. From a fit to the dilepton p and p⊥ spectra, we determine the mixing parameter to be χB=0.178-0.040 +0.049. © 1990.

Abstract: We have measured the forward-backward asymmetry in Z 0 → b b decays using hadronic events containing muons and electrons. The data sample corresponds to 118 200 hadronic events at √s≈Mz. From a fit to the single and dilepton p and P⊥ spectra, we determine A b b =0.130 −0.042 +0.044 including the correction for B 0 − B 0 mixing.

Abstract: Whatever the field, major change implies as much as deep transformation of thinking i.e to put in network new skills in particular, those made available by the availability of new technologies. In this context, only one individual cannot join together all necessary skills. It becomes clear that the goal of space valorization cannot be considered without relational investment between the partners and their accumulated background. The local empowerment concerns a collective phenomenon of acquisition and development of skills rests on an learning way appropriate to the potential of the territory to form or promote. The local mediation sets for objective the creation of relations between pre-existent skills and their transfer between the actors, individuals or groups, private or public. But the capacity of the territory to solve these problems will depend closely on the richness of the network and co-operations which it shelters or it will suggest.

Abstract: We have searched for charged and neutral leptons. We exclude stable Dirac neutrinos below 42.8 GeV and stable Majorana neutrinos below 34.8 GeV. From a search for unstable neutrinos we exclude masses below 46.4 GeV (Dirac) and below 45.1 GeV (Majorana). We exclude all masses of sequential charged and neutral leptons, except if both masses are larger than 42.8 GeV (for stable Dirac neutrinos). All mass limits correspond to 95% CL.

Abstract: Abstract. The aim of the study was to evaluate the differences in milk coagulation properties in three groups of dairy cows receiving the dietary supplements Panamin Animal and Panamin Detox. The present group production experiment was conducted in the experimental cattle farm of the Agricultural Institute – Stara Zagora with three groups (two experimental and one control) each comprising 11 lactating dairy cows between November 2016 and March 2017. The cows are kept freely, the milking is in a hall “Fish bone”, and the groups were fed balanced rations compliant with milk yield and live body weight of cows, supplemented with 0.50 g/day of two natural dietary additives – Panamin Animal and Panamin Detox in line with recommendations of the manufacturer. The following parameters were monitored: rennet coagulation time (min) – RCT and curd firmness (mm) – a30. The analysis of individual milk coagulation properties was done on 436 milk samples from cows. Individual milk samples were obtained during the morning milking without adding preservative. The analysis of milk coagulation ability was evaluated at the laboratory of the Agricultural Institute – Stara Zagora by means of Computerized Renneting Metter – Polo Trade, Italy. The obtained phenotypes were corrected for main factors influencing test-day milk yield. The used model considered each test day milk yield as independent observation and unbiased estimates of traits were obtained by a linear mixed-effects model. The supplementation of cows’ ration with dietary supplements Panamin Detox and Panamin Animal had a statistically significant beneficial effect on milk coagulation properties of milk (p

Abstract: Polymer-dispersed liquid crystals (PDLC) provide the opportunity to achieve reliable, cheap and commercial elements for switchable holographic devices. In the present work holographic recording techniques are used to form switchable gratings in PDLCs. Depending on the initial reactivity of the mixture, Bragg and Raman-Nath gratings are obtained. The first ones show higher efficiency for s-polarization, which does not hold in the case of Raman-Nath gratings Different exposure power of the writing beams results in different diffraction efficiency. The switching characteristics of the recorded gratings are studied. The switch-off state is obtained at about 2V/μm for p-polarization in the first diffracted order in thin (Raman-Nath) gratings. The angular selectivity of these gratings is also investigated. The influence of the reconstructing wave polarization azimuth on the diffraction efficiency is studied.

Abstract: Using a sample of e+e− annihilation events collected at the Z resonance corresponding to an integrated luminosity of 11.2 pb−1, we have searched for γX final states where X represents stable, weakly interacting particles and the energy of the photon is greater than 1 2 E beam . No events were found. The results have been interpreted within a composite Z model and a supergravity model with a light gravitino.

Abstract: From a fit to the impact parameter distribution of lepton tracks from semileptonic b decay, the lifetime of B-hadrons produced in e + e − collisions at the Z 0 is measured to be 1.32±0.08 (stat.)±0.09(syst.) ps. Combined with an earlier measurement of the branching ratio Br(B→l ν X), the CKM matrix element | V cb | is determined to be 0.046±0.002 (exp.) −0.003 +0.004 (theory).

Abstract: We have searched for lepton flavour violation in Z0 boson decays into lepton pairs, Z0→μτ, Z0→eτ, and Z0→eμ. The data sample is based on an integrated luminosity of 10.4 pb-1 corresponding to 370 000 Z0’s produced. We obtain upper limits on the branching ratios of 4.8 X 10-5 for the μτ 3.4 X 10-5 for the eτ and 2.4 X 10-5 for the eμ decay modes at the 95% confidence level., Facultad de Ciencias Exactas

Abstract: We have measured the properties of Z0 → b b decays using a sample of 944 inclusive muon events, corresponding to 18 000 hadron events obtained with the L3 detector at LEP. We measured the partial decay width of the Z0 into b b , Γ b b =353±48 MeV , and we determined the vector coupling of the Z0 to the b quark; grmv2(b)=0.095±0.047. We measured the forward-backward charge asymmetry in e+e− → b b events at √s≈Mv, and obtained A b b =13.3±9.9% .

Abstract: The polyvinylidene flourede is known for its piezo- and pyroelectric properties. At the other hand the non-linear optical properties of nanocrystals of semi-conductors inbeded in polymer matrixes are of great interest. We studied the PVDF-CuxS couple. Our aim was to obtain good adhesion of a PVDF film with thickness of 25 mm, by a surface modification of consecutive deflouridation and one aclrylat monomer annexation. CuxS was adjourned from a solution with the help of a oxidation-reduction process, 1 µm thick and a resistivity of 1.3 kΩ.m measured with two point method.

Abstract: A four-factor Response surface methodology central composite rotatable design was used to study the effect of moisture content, barrel temperature, screw speed, and feed screw speed on sectional expansion index and bulk density during extrusion of chickpea instant semolina for the purpose of instant product. The regression models for the investigated responses were highly significant (according to P-value) with satisfactory coefficients of determination (R2) 0.894 and 0.957. These results show that the predicted models for the investigated responses are adequate, indicating that the second-order polynomial model could be effectively used to represent the relationship between the selected parameters. The study showed that the expansion was influenced by moisture and temperature and it increased with increasing temperature for moisture content from 20 to 23% and after that decreased. Bulk density decreased with increasing feed moisture and barrel temperature in the extruder. The most important consequences for the science and practice resulting from the conducted research are that the resulting extrudates after grinding can be successfully used for the preparation of instant product with good characteristics, such as bulk density and sectional expansion index.

Abstract: In the current work we submit experimental data pertaining to the role of the heat-mechanical modification Ton the structural reorganization of poly (ethylene terephthalate) (PET) as-spun yarns. The thermal deformation experiments were realized using specialized device designed and produced in the author's laboratories. The structural characterizations of the studied fibers after the above described heat-mechanical treatments were realized using differential scanning calorimetry (DSC), wide-angle X-ray scattering (WAXS) and density measurements. Have been identified dependences between the heat-mechanical deformation parameters and the occurred in the studied PET fibers structural reorganization.

Abstract: The linear electro-optic response of polymer-dispersed liquid crystal films has been studied. Micrometer-sized droplets of a cyanobiphenyl mixture (E7) were formed in a Norland Optical Adhesive 65 photopolymer by photopolymerization-induced phase separation. Samples with various average nematic droplet sizes were systematically investigated. The temperature dependence of the first-harmonic electro-optic spectra was obtained. Peculiar peaks and double peaks in the phase spectra were found at temperatures close to the clearing point. Samples with narrow distributions of droplet sizes were characterized by a double peak of the amplitude spectra in the low-frequency range. A flexoelectric origin of the first-harmonic spectra in confined nematic systems is discussed.

Abstract: Research on the biological effects and on critical-temperature alarm indicators for fire safety often requires the use of non-metallic and reliable temperature sensors. For such applications, we investigated the temperature dependence of the spectral response of a pure cholesteric liquid-crystal temperature indicator and of a polymer/liquid crystal mixture. We observed a modulation of the intensity of transmitted monochromatic light, in accordance with the temperature changes. We emphasize that the modulation occurs over a wide temperature range outside the active temperature of the thermochromic liquid-crystal indicator. Such behavior suggests the possibility of using these liquid crystals in a wider temperature range, under appropriate conditions. The spectral response of the liquid crystal in its active temperature range shows that a thermochromic liquid crystal indicator may be practically used as a precision thermometer.

Abstract: We report on a comparison of isolated hard photon production in hadronic Z decays with the predictions of a next-to-leading order matrix-element calculation. We constrain the quark electroweak couplings to the Z boson with a simultaneous fit to three direct photon distributions, and combine this result with an independent constraint from our measurement of the total hadronic width of the Z, obtaining cu = 0.92 ± 0.22 and cd = 1.63 ± 0.15 where c u,d = 4( g V 2 + g A 2 ) u,d . Our results are consistent with standard model predictions.

Abstract: The article submits new experimental data concerning to the role of combined thermo-mechanical treatments on the structural development of freshly moulded uncrystallized but crystallizable poly (ethylene terephthalate) (PET) fibers. The object of the present work is PET as a thermoplastic polymer with a large practical application. The report is devoted to the influence of the heat-mechanical modification temperature on the structure rearrangement in uniaxially orientated amorphous PET. The heat-mechanical modification of the investigated yarns and the optical measurements were realized by specialized gears constructed and built in the author's laboratories. The fibers heat-mechanical modification includes samples annealing at constant temperature above their glass transition temperature (Tg) without strain stress. The yarn annealing has been followed from well defined uniaxially strain-loading with values from 0 MPa up to 30 MPa during two minutes. The optical measurements were carried out by an optical system using a polarization microscope and a CCD camera. The obtained experimental data has been analyzed by Mocha-1.2 (Jandel Scientific) software. There are established dependences between the heat-mechanical modification mode and the structural rearrangements running in the studied PET samples.

Abstract: Within a context of evolution and the rapid integration of digitization in university publishing, the fields of the humanities and social sciences, and in particular those of textbooks, do not appear to have found a satisfactory distribution model. In this article, we shall attempt to explain in what measure this sector is different from other areas of university publishing and what hypotheses can be put forward for its future development. Having suggested a carving up of the university publishing market, we would like to place it briefly in an international context. On the basis of this finding, we will present the hypothesis of aggregation: why this should be required, why it does not yet exist and which needs it will respond to. We shall conclude by summarizing these points which we believe are key to the development of a digital university offer in France for the humanities and social sciences.

Abstract: The L3 detector at LEP has been used to determine the number of light neutrino families by measuring the cross section of single photon even in e+e - collisions at energies near the Z° resonance. We have observed 61 single photon candidates with more than 1.5 GeV of deposited energy in the barrel electromagnetic calorimeter, for a total integrated luminosity of 3.0 pb-1. From a likelihood fit to the single photon cross sections, we determine Nv = 3.24 ± 0.46 (statistical) _+ 0.22 (systematic)., Facultad de Ciencias Exactas
