Analysis of introduction mitigation measures to reduce the presence of acrylamide in foods in Slovenian kindergartens
No full textUvod: Akrilamid je industrijska kemikalija, ki se uporablja v proizvodnji poliakrilamidov. Akutna izpostavljenost visokemu odmerku akrilamida pri ljudem in pri živalih povzroča spremembe v centralnem živčnem sistemu, ob kronični izpostavljenosti nižjim odmerkom pa povzroči periferno nevropatijo. Akrilamid je opredeljen kot onesnaževalo in v živilski verigi predstavlja kemično tveganje. Z Uredbo komisije (EU) 2017/2158, ki je v veljavi od aprila 2018, so bili opredeljeni blažilni ukrepi za zmanjševanje akrilamida v hrani. Nosilci živilske dejavnosti so morali sprejeti ukrepe, s katerimi zagotavljajo zmanjševanje ravni akrilamida v proizvodnji in pri pripravi živil. Namen: Namen magistrskega dela je bil z raziskavo preveriti poznavanje akrilamida in upoštevanje Uredbe Komisije (EU) 2017/2158 pri kuhinjskem osebju v vrtčevskih kuhinjah. Metode: V okviru raziskovalnega dela smo uporabili kvantitativno standardizirano metodo anketnega vprašalnika. Za pretvorbo vprašalnika v elektronsko obliko smo uporabili aplikacijo 1KA, ki omogoča storitev spletnega anketiranja. Rezultati: V raziskavi je sodelovalo 166 oseb, ki delajo v vrtčevskih kuhinjah. 96 % anketirancev je že slišalo za akrilamid, 91 % anketiranih oseb je prepoznalo akrilamid kot rakotvorno kemikalijo, 97 % anketirancev pa je pravilno izbralo živila, ki lahko vsebujejo najvišje deleže akrilamida. V sklopu vprašanj, ki so se navezovala na upoštevanje blažilnih ukrepov Uredbe Komisije (EU) 2017/2158, priloge II, dela A, smo ugotovili, da jih kuhinjsko osebje v večini primerov pozna in upošteva. Analiza povezanosti med neodvisnimi in odvisnimi spremenljivkami je pokazala povezavo med stopnjo izobrazbe in odgovori o poznavanju akrilamida ter upoštevanju blažilnih ukrepov. Razprava in zaključek: Rezultati so pokazali, da je vrtčevsko kuhinjsko osebje seznanjeno s problematiko akrilamida v prehrani. Z vzorčenjem pripravljenih jedi in s kemijsko analizo vzorcev na prisotnost akrilamida pa bi bilo v prihodnje smiselno preveriti dejansko stanje v kuhinjah, saj bi upoštevanje blažilnih ukrepov tako lahko preverili v praksi. S kuhinjskimi delavci bi lahko izvedli intervjuje, na tak način pa ugotavljali njihovo mnenje in vtise o raziskovani temi. Podali smo primer sheme prikaza najpomembnejših informacij o akrilamidu z barvno lestvico pravilne zapečenosti izbranih živil, ki bo kuhinjskemu osebju lahko v pomoč.Acrylamide is an industrial chemical used in the production of polyacrylamides. Acute exposure to high doses of acrylamide in humans and animals results in changes in the central nervous system, and chronic exposure to lower doses causes peripheral neuropathy. Acrylamide is defined as a pollutant and poses a chemical risk in the food chain. Commission Regulation (EU) 2017/2158, which has been in force since April 2018, defined mitigation measures to reduce acrylamide in food. Food business operators had to take measures to ensure that acrylamide levels were reduced in food production and preparation. Purpose: The purpose of these master\u27s thesis was to test the knowledge on the acrylamide in food and compliance of the kindergarten kitchen staff with Commission Regulation (EU) 2017/2158. Methods: In the research work we used a quantitative standardized method of the questionnaire. To convert the questionnaire into an electronic form, we used the EnKlikAnketa application, which enables an online survey service. Results: 166 people working in kindergarten kitchens participated in the research. 96% of respondents had already heard of acrylamide, 91% of respondents identified acrylamide as a carcinogenic chemical, and 97% of respondents correctly chose foods that may contain the highest amounts of acrylamide. We found out that most participants are aware of and comply with mitigation measures of Commission Regulation (EU) 2017/2158, Annex II, Part A. The analysis revealed a correlation between the education level and the the knowledge on acrylamide and the consideration of mitigation measures. Discussion and conclusion: The results implied that the kindergarten kitchen staff is familiar with the hazards of acrylamide in the diet. We have developed a poster with the most important information on the acrylamide formation and a color scale for the appropriate baking of selected foods. This may assist the kitchen staff. Day to day compliance with mitigation measures could be verified in practice by sampling and chemical of prepared dishes for the to determine the actual situation in kitchens in the future. Interviews could be conducted with kitchen staff to find out their opinions and impressions on the topic

Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
Corrosion and Electrochemical Properties of Laser-Shock-Peening-Treated Stainless Steel AISI 304L in VVER Primary Water Environment
No full textLaser Shock Peening (LSP) is a surface treatment technique for metallic materials. It induces plastic deformation at the surface of up to around 1 mm in depth. This process introduces residual stresses that lead to strain hardening, and potentially improvements in fatigue, stress corrosion cracking (SCC) and general corrosion behaviour in many, but not all, corrosive media. In this paper, two specimens made of AISI 304L stainless steel, one LSP-treated and one un-treated, were tested at 280 °C and 8 MPa in VVER (or PWR) primary circuit water chemistry using in situ Electrochemical Impedance Spectroscopy (EIS). This experiment serves to qualify the influence of LSP on the changes in corrosion behaviour in high-temperature, high-density water. The residual stress (RS) measurement of the surface showed a compression RS. Before LSP treatment, RS at the surface was 52.2 MPa in the rolling direction 0°RD and 10.42 MPa in the transverse rolling direction 90°RD. After the treatment, surface RS was −175.27 MPa and −183.51 MPa for Scan and TScan directions, respectively. The effect of compressive RS at the surface was studied and showed an increase in corrosion rate. The analysis of oxide layer by SEM revealed differences between LSP-treated and untreated AISI 304L specimens and their connection to corrosion rates
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
