Observables of non-equilibrium phase transition

A rapidly expanding fireball which undergoes first-order phase transition will supercool and proceed via spinodal decomposition. Hadrons are produced from the individual fragments as well as the left-over matter filling the space between them. Emission from fragments should be visible in rapidity correlations, particularly of protons. In addition to that, even within narrow centrality classes, rapidity distributions will be fluctuating from one event to another in case of fragmentation. This can be identified with the help of Kolmogorov-Smirnov test. Finally, we present a method which allows to sort events with varying rapidity distributions in such a way, that events with similar rapidity histograms are grouped together.Comment: contribution to NICA white paper, 5 pages, revised version with minor corrections, mainly languag

Fluctuating shapes of the fireballs in heavy-ion collisions

We argue that energy and momentum deposition from hard partons into quark-gluon plasma induces an important contribution to the final state hadron anisotropies. We also advocate a novel method of Event Shape Sorting which allow to analyse the azimuthal anisotropies of the fireball dynamics in more detail. A use of the method in femtoscopy is demonstrated.Comment: contribution to Proceedings of the XXIV Baldin seminar on high energy physics problems (Relativistic Nuclear Physics and Quantum Chromodynamics), Sept. 17-22, 2018, Dubna, Russia, 6 page

Optimal Levels of Inputs to Control Listeria monocytogenes Contamination at a Smoked Fish Plant

Reducing the incidence of listeriosis from contaminated food has significant social health benefits, but reduction requires the use of additional or higher quality inputs at higher costs. We estimate the impact of three inputs in a food processing plant on the prevalence of L. monocytogenes contaminated finished cold smoked salmon. These three inputs were non-contamination of the raw fish fillets, non-contamination of the plant environment, and rate of glove changes on workers. We then estimate the levels of these inputs to use such that the marginal cost of these inputs become equal to the increased social health benefit of reduction in human listeriosis. Since the costs of these inputs are borne by the food processing plant, which may not be able to secure a higher product price because of asymmetric information, we show how social sub-optimal use of these inputs may result.Food Consumption/Nutrition/Food Safety,

W63+ and W64+ ionization by protons and photons

In this work we investigate the ionization by proton impact, and photo ionization, involving highly charged ions of W, in particular the Ne-like W64+ and Na-like W63+ which are more likely to appear in ITER plasma. Total cross sections are calculated in the continuum-distorted-wave-eikonal-initial-state (CDW-EIS) approximation for ion-impact, while two completely different methods are used for photoionization: a perturbative dipolar aproach and the recently introduced Sturmian model.Fil: López, Sebastián David.

AN ACADEMIC WRITING NEEDS ANALYSIS OF CZECH UNIVERSITY GRADUATE STUDENTS

The present paper presents the results of a needs analysis conducted among Czech students involved in a Master’s degree programme English Language Teacher Education. The aim was to identify their academic writing needs on the basis of a needs analysis questionnaire and a linguistic analysis of their written discourse in order to find out whether there are divergences between their ‘wants’ and ‘lacks’ (Hutchinson & Waters 1987). The results indicate that the students’ previous tuition at Bachelor’s level focused primarily on lexico-grammatical features of academic style such as text organizing devices, academic vocabulary, grammatical structures and citation styles. However, other areas essential to writing a successful Master’s thesis, such as evaluation and interpretation of results, conveying personal viewpoints and communicating with the reader or acknowledging research limitations, were ascribed a somewhat lower importance by the students, suggesting the existence of a divergence between the students’ ‘wants’ and ‘lacks’. The findings concerning the students’ perception of the writing process also concur with the finding of the authors’ previous research (Dontcheva et al. 2020) into the Theme zone in Czech students’ Master’s theses, which has indicated that Czech Master’s students tend tooveruse textual Themes expressed by linkers and underuse interpersonal Themes realised by stance devices

The question is in the form of a description test on the implementation of online learning during the Covid-19 pandemic which shows that most students have difficulty answering questions about mathematical logic material, this underlies the research. This problem occurs because students do not understand the existing statements and the concept of determining the truth value of a compound statement. The purpose of the research is to find out more about students' mistakes when answering mathematical description questions through analysis and description of some students' mistakes when answering questions on mathematical logic material, therefore this study uses descriptive methods with a qualitative approach. The research subjects were students of class XI OTKP (Office Automation and Governance) at one of the Vocational High Schools in Cimahi with a total of 18 students. The stages in this research are planning, implementation, and reporting. The results of the student description test of three questions were used to collect data. The analysis technique used is data reduction, presenting the data and then drawing conclusions. The results and discussion of this study indicate an average of 33.33% of students with low abilities. The percentage of student errors is 44.44% with moderate criteria and 22.22% with low criteria

European payment services directive 2 in North Macedonia : are we ready to comply?

The Payment Services Directive 2 (PSD2) will have a profound and direct impact on the European banking industry. It is also widely accepted as a regulation producing ripple effects both in the banking and other sectors in and beyond Europe. Extending the first Payment Services Directive, PSD2 is intended to strengthen the security of online transactions, promote a more efficient and integrated payments market, protect customers, provide a level playing field between different payment service providers, and resolve all security gaps and risks that were not previously addressed. PSD2 creates space for innovative financial services, and by developing and advancing openness in banking, it calls into question the traditional banking models and imposes important operational and technological amendments to banks, their vendors, collaborates and the entire banking ecosystem mechanisms and function. PSD2 principles are also important for regulating the new Account Information Services (AIS) and Payment Initiation Services (PIS) along with the Third Party Providers (TPPs) - AISPs and PISPs. By properly synthesizing and analyzing the financial information from different banks and institutions, the former act as aggregators for the various customers. The latter, on the other hand, look to arrange and administer the financial transactions of their customers. Given the above considerations, this paper aims at answering three main questions about the PSD2. At first, we will take an in-depth look at the concepts and principal goals of the European Directive. Secondly, we will examine the implications of the EU regulation on the (1) legislative measures in the area of financial services and (2) day-to-day operations of both the central bank and commercial banks, or any other entity that may also be affected. Finally, this paper may serve as a guideline for the queries and dilemmas that managers in North Macedonia have about the PSD2, and may also assist by providing certain instructions and recommendations in managing change during the implementation process

Processing of meats and cardiovascular risk: time to focus on preservatives

Dietary guidelines emphasize selecting lean (low-fat) meats to reduce saturated fat and cholesterol, but growing evidence suggests that health effects may relate to other ingredients, such as sodium, heme iron, or L-carnitine. Understanding how meats influence health, and on which nutrients this relationship depends, is essential to advise consumer choices, set guidelines, and inform food reformulations. A recent study published in BMC Medicine involving 448,568 participants in 10 European countries, provides important evidence in this regard. After multivariate adjustment, intake of unprocessed red meat was not significantly associated with total or cause-specific mortality; conversely, intake of processed meat was associated with a 30% higher rate of cardiovascular disease (CVD) (per 50 g/day, relative risk 1.30, 95% confidence interval 1.17 to 1.45) and also higher cancer mortality. These findings are consistent with our previous meta-analysis, based on smaller studies, showing strong associations of processed meats, but not unprocessed meats, with CVD. Preservatives are the notable difference; the calculated blood-pressure effects of sodium differences (around 400% higher in processed meats) explain most of the observed higher risk. Although unprocessed red meats seem to be relatively neutral for CVD, healthier choices are available, including fish, nuts, legumes, fruits, and vegetables. Public-health guidance should prioritize avoidance of processed meats, including the low-fat deli meats currently marketed as healthy choices, and the food industry should substantially reduce sodium and other preservatives in processed meats.
