Published: November 2021

Degradation of chitosan in swollen state with hydrogen peroxide solution (5% w/v) by γ-irradiation was investigated. Molecular weight (Mw) of irradiated chitosan was determined by gel permeation chromatography (GPC). Fourier transform infrared (FT-IR) and ultraviolet-visible (UV-vis) spectrawere analyzed to study the structure changes of degraded chitosan. The results showed that the chitosan of low Mw ~30-45 kDawas efficiently prepared by γ-irradiation of chitosan swollen in hydrogen peroxide solution at low dose less than 20kGy. The main structure as well as the degree of deacetylation of the degraded chitosan was almost no significant change. Furthermore, the radiation degradation yield (Gs) was remarkably enhanced by the presence of H2O2. The obtained low Mw chitosan revealed high antimicrobial activity for E. colithat can be used for food preservation and other purposes as well.

Authors: Hoang Minh Giang , Hoang Tan Hung , Nguyen Phu Khanh
Published: November 2021

Recently, CTF, a version of COBRA-TF code is reviewed to validate its simulation models by several experiments such as Castellana 4x4 rod bundle, EPRI 5x5 bundle tests, PSBT bundle tests and TPTF experiment. These above experiments provide enthalpy, mass flux (Castellana), temperature (EPRI) and void fraction (PSBT, TPTF) at exit channel only. In order to simulate PWR rod bundle flow behavior, it is necessary to review CTF with more experiment in high pressure condition and it is found that the ENTEK BM facility is suitable for this purpose. The ENTEK BM facility is used to simulate Russia RBMK and VVER rod bundle two phase flow with pressure at 3 and 7 MPa and it gives measured void fraction distribution along the channel. This study focus on two points: (a) accuracy assessment between CTF’s void fraction distribution predictions versus experiment void fraction distributions and (b) investigation of void fraction prediction uncertainty from propagation of input deviations caused by measured accuracy.

Authors: Nguyen Ngoc Tuan , Duong Van Dong , Bui Van Cuong , Pham Thanh Minh , Nguyen Thi Hang
Published: November 2021

Lutetium-177 (177Lu) radioisotope used for medical purposes has been produced at the Dalat Nuclear Research Reactor during 2012-2014. The product was synthezed by the activation reaction 176Lu (n,γ) 177Lu. The target was Lutetium oxide with an abundance of 176Lu being 2.59% and the irradiation was conducted with a neutron flux of 2.1013 n cm-2 s-1. The activity of the 177Lu product was 39,59 Ci g-1 after 108 hous of the irradiation. The yield of this method was much higher compared to those of the reaction 176Yb(n, γ)177Yb → 177Lu + β- which for the same time could be 15mCi/50mg only. Because of low specific radioactivity the preparation of 177Lu made from the activation of 176Yb cannot be applied for the medical purposes. Additionally, the separation yield of 177Lu from 177Yb is rather low, it is usualy of approximately 70%.
Enhancement of the immunity and body weight gain in broiler by feeding with the brewer’s yeast β-glucan degraded by gamma Co-60 radiation
Authors: Le Quang Luan , Nguyen Thanh Long
Published: November 2021

The insoluble β-glucan extracted from the cell wall of brewer’s yeast was dispersed in deionized water for swelling, then irradiated in order to degrade into water-soluble β-glucan. The results revealed that the water-soluble β-glucan contents in the irradiated samples were increased with radiation dose to 25.89, 49.07 and 66.71%; whereas their molecular weight (Mw) decreased to 48.1, 23.0 and 10.8 kDa by gamma irradiation at 100, 200 and 300 kGy, respectively. The supplementation of poultry feed with the radiation degraded β-glucan enhanced both non-specific (total white blood cells, lymphocytes, neutrocytes) and specific immune components (anti-Newcastle disease, anti-Gumboro disease virus and anti-infectious bronchitis virus antibodies) in the broilers. In comparison with the control, broiler fed normal poultry foodstuff without β-glucan, the supplementation of radiation degraded β-glucan not only increased the survival rate of the testing broiler about 33.3% and their average body weight of about 24.4%, but also reduced the feed conversion rate from 4.8 to 3.1 kg. The β-glucan oligosaccharides that having Mw of about 25 kDa produced by gamma irradiation at 200 kGy showed the highest effect on the growth performance and immunomodulatory capability in the immune system of the testing broilers. This product is promising to be applied for production of the safe stimulator of immunity for broiler chickens.

The article presents possibilities for studying fiction text in 1.– 4. grade through groups of interactive methods: for games and presentations, for collecting information, situational, for generation and creative aggregation of ideas, for discussions. These methods are directed to develop cognitive reading and understanding skills, oriented to search and extract specific information; to make direct statements; to interpretate and aggregate facts and ideas; to analyze and evaluate the content, language and structure of the text. I support the understanding that every kind of understanding in reading fiction text has its own manifestations associated with both genre differentiation and general genre elements such as theme, idea, story, composition, problems, literary hero, artistic language.
A Taxonomy Approach to Fake News
Authors:   University of National and World Economy, Bulgaria, Valchanov Ivan
Published: November 2021

The development of the Internet and social media and networks as a media environment and communication channels combined with the specificity of the journalistic profession in the online environment are a factor which contributes to the emergence and proliferation of fake news. The lack of reliable fact checking by the media and the fast news consumption by the public lead to mass disinformation about certain issues or subjects. The current paper examines fake news from several points of view and describes the models of their use – as harmless jokes, as lack of journalistic competence or professionalism and as means of manipulation and intentional misleading of public opinion. The attempts of big media corporations to fight fake news are also described.
The Post-Truth Era: Algorithms, Emotions, Power
Authors:   ", Pavlova Iliana ,   St. Cyril and Methodius",   University of Veliko Tarnovo
Published: November 2021

The paper aims to examine post-truth, considering its theoretical aspects and following the communication grounds for its appearance. The paper suggests that the Post-truth Era is a result of algorithmically managed social interactions and the automation of communication. The Internet of Things, the ubiquitous media presence and the algorithmic power transform „The Age of Mechanical Reproduction” (Walter Benjamin) into „a Posttruth Era”. In the digital world of the 21st century – a world completely fragmented into data and market segments, the media technologies not only reproduce and re-create reality, but also take the next step and create an entirely new reality. Based on the critical survey of various articles and theoretical approaches the paper identifies the problematic areas that could engender a future discussion, and draw attention to post-truth as a problem and its relevance to the modern world.

Crisis PR in the Post-Truth Era
Authors: Nikolova Mariya
Published: November 2021

The paper outlines some of the challenges that PR experts are facing in their work in the so-called „Fake News Era”, dominated by misinformation and the need for verifying the facts published in social and traditional media. The main thesis of Gьnter Bentele’s theory of public trust is used to frame the basic idea about the lack of trust in the media in general. Some of his conclusions drawn in the 1990s, are similar to the results summarized today by two reports: Cision’s „State of the Media Report” (2017) and Edelman’s „Trust Barometer” (2017). The paper also presents a few case studies, related to the distribution of fake news that damage the prestige and the reputation of the affected companies (Pepsi Co, New Balance, Ferrero Croup). It poses the question about the extent to which we can talk about corporate communication management and strategies in the post-truth era and whether it would be more appropriate to include a Rumor Management strategy in the corporate communication strategy arsenal when a corporation needs to react to a piece of fake news in the post-truth era.
Fake News in Corporate Communication
Authors:   ", Khristova Khristina ,   St. Cyril and Methodius",   University of Veliko Tarnovo
Published: November 2021

The paper examines the impact of fake news on the relationship between companies and their strategic audiences. The text is structured into two parts. The focus in the first part is on the structure of corporate communications and the model of successful corporate policy presented as a projection of the idea of the business of trust. The second part highlights the main aspects of the development of the cosmetic giant „L’Oreal”, which has preserved its image as a strong brand and an ethical company in the conditions of hypercompetitiveness and fake news. The study is based on Van Rieland Fombrun’s theory of corporate communications as a polyfunctional concept and on Kotler’s idea of market-oriented strategic planning, providing an advantage to firms in situations of risk and dynamic social transformations.

Authors: Cheung Douglas , Frankel Jed , Tut Pavinder , Komisarenko Maria , Martin Lisa , Jewett Michael , Finelli Antonio
Published: November 2021

Introduction: Active surveillance (AS) of small renal masses (SRM) is increasingly recognized as a safe option. A recent U.S. study found that half of patients receiving treatment on AS were for preference, but these findings may not be generalizable to other jurisdictions and healthcare models. We aimed to investigate AS failure rates and causes among a contemporary biopsy-evaluated cohort in Canada.
Methods: A retrospective review was performed of SRM patients on AS undergoing treatment at our tertiary care center (1999–2018). All patients had undergone renal biopsy and been diagnosed with renal cell carcinoma (RCC). Demographic and clinical parameters surrounding the decision to treat were extracted from chart review. Indications for treatment were dichotomized into clinical (radiographical) progression or preference. Qualitative assessment of clinic notes confirmed treatment indication. Ethics approval was obtained.
Results: A total of 38 SRM-RCC patients who underwent treatment on AS were identified, of which 29 had been on AS ≥1 year. Most (75.9%) were male, and the mean age beginning AS was 65.9±9.0 years. Most patients had clear-cell RCC with low-grade disease. Seventeen of 29 (58.6%) patients experienced clinical progression after 3.82 (2.57–7.16) years, whereas preference accounted for 12/29 (41.4%) after 2.22 (1.69–3.53) years (time-to-treatment p=0.032). The longest duration on AS was 14.2 years prior to clinical progression. No patients had metastatic progression before treatment.
Conclusions: Two-fifths of patients received treatment for preference and at a much higher rate vs. clinical progression. These findings suggest a clinical gap where effective patient counselling, prior to and during AS, may improve adherence.
