Abstract
Light emitted in the wavelength range of 400–500 nm causes a very significant photochemical effect on the retina. At certain doses of blue light energy can cause damage to the retina, so the study of the safety of blue light projectors used in domestic conditions is an urgent task. The aim of this work is to study the photobiological safety of light image projectors with light emitting diodes. The paper analyzes the requirements for photobiological safety of tube systems and methods for assessing the danger of blue light of projectors that use LED light sources. The information is provided on the equipment for measurement of spectroradiometric and photometric parameters of beams of projectors, as well as features of radiance and irradiance measurement of lamp systems in which lens optics is used.
The results of research of photobiological danger levels of blue light of image projectors intended for use in household conditions are presented. It is shown that at a distance of 1 m from the projector (the distance for which the level of photobiological safety of blue light is normalized), the investigated type of projector belongs to the risk group RG1 (insignificant risk). When the distance is reduced to 0.5 m and 0.2 m, the risk of blue light increases to the RG2 group (medium risk).
The features of the requirements for photobiological safety of blue light of image projectors used in everyday life, educational institutions and in other conditions are analyzed. In particular, the risk group at a distance of 1 m from the collimator lens should not exceed RG1, and it is recommended to put an additional label on the projector indicating the risk group RG1 and mark this information in the user manual.
Conclusions are made on the compliance of the studied low-power image projectors with the safety conditions of blue light, established by the international standard IEC 62471-5 (Photobiological Safety of Lamps and Lamp Systems – Part 5 Image Projectors).

The main task of the research is to improve technical and economic indicators of weight measuring system and to increase the efficiency of its research on the basis of cost-optimal planning of experiments.
A system with a measuring tray has been developed, and it is different from existing systems with a possibility to control inclination angle of a tray, moisture content and temperature of a bulk substance, what provides better accuracy of mass measurement.
The researches of weight measuring system were performed using the following methods of cost-optimal experiment planning: taboo search, particle swarm method, exhaustive search, Gray code based method. It gave possibility to reduce cost of implementing the experiment.
To perform the research of weight measuring system, a plan of a full-factor experiment was selected, which was optimized for the cost of its implementation by using a method based on the Gray code.
In the result of research, mathematical models in coded and natural values of factors were obtained. They characterize the dependence of the measurement acceptable error on such indicators as the angle of the measuring tray, the humidity of the bulk material, the coefficient of friction of the bulk material in motion. Using a mathematical model, rational values of the design parameters of the weight measuring system were obtained, which provide high accuracy (measurement acceptable error does not exceed 0.20%): the angle of the weight measuring tray α = 41.9°; humidity of loose material W = 14%; the coefficient of friction of the bulk material in motion fd = 0.70.
The developed weight measuring system can be widely used for dosing of bulk materials in various technological productions.

Abstract
The aim of this study was to observe the efficiency of ozone transferred by an airstone bubble diffuser, using two ozone generators with different output of ozone (5 g.h–1 ‒ G1; 15 g.h–1 ‒ G2). The retention of ozone in ozonised distilled and potable water and the devitalisation effects on E. coli in the water were also noted. Ozone was introduced to two types of potable water of different composition intended for mass consumption, (MC)a and (MC)b, distilled water, and well water intended for individual consumption. The devitalisation effect of ozone on E. coli in well water (WW) and added to potable and distilled water was observed. The results of our study showed that under the conditions used, the level of ozone during ozonisation with G1 increased more rapidly in distilled water and after termination of ozonisation, the retention of ozone in distilled water was a little lower in comparison with the potable water. The devitalisation of E. coli either naturally present in the water or added to it required the level of ozone close to or equal to 0.25 mg.l–1.

Abstract
In this study, we assessed the effect of humic substances on the changes of some mineral (Ca, Mg, Cu and Zn) content in the thigh and breast muscle of broilers. Group 1 (G1) was supplemented with 0.7 % Humac Natur Mycosorb (HNMy), and G2 with 0.3 % HNMy. The control group (GC) received a basal diet without any supplements. In the breast muscle of broilers from the group G1 we found a statistically significantly higher (P < 0.05) Ca content and significantly reduced (P < 0.05) in the thigh muscle Ca content from the group G2 compared to the control group (GC). A statistically significant increase in Mg content (P < 0.05) was analyzed in breast muscles in the group G1 and also significant reduction (P ≤ 0.01) in Cu in the breast and thigh muscles was found in the group G1 and in the breast muscle from the group G2 compared to the GC. Significantly lower content of Zn (P ≤ 0.05) was found in the breast and thigh muscles of broilers in the group G2 and strong positive correlation (r = 0.9093) were observed between Ca in breast muscle from the group G2 and Ca in thigh muscle from the control group. A negative correlation (r = –0.7656) was shown for Mg between thigh muscle from the group G2 and Ca in thigh muscle from the GC. A strong negative correlation was confirmed (r = –0.9221) for Zn content in breast muscles between groups G2 and G1. The high positive correlation for Zn was occurred between breast muscle from the control group and thigh muscle from the group G1 (r = 0.9786).

Authors: Balicka A. , Lapšanská M. , Fekiačová V. , Trbolová A. 
Published: October 2021

AbstractEosinophilic keratitis is a disease occurring in cats, horses and rabbits. Its clinical signs include blepharo-spasm, discharge, chemosis, conjunctival hyperaemia and the presence of corneal ulceration. The typical signs of the disease are white to pink plaques on the cornea accompanied with keratitis. The diagnosis of the disease has to be confirmed with cytology examination and the presence of eosinophils and mast cells in the specimen. Local application of corticosteroids and cyclosporine has good therapeutic effect and has been recommended in all affected species. In samples collected from cats, the presence of feline herpes virus DNA has been reported. Eosinophilic keratitis might be caused by an aberrant immune response or reaction to unknown allergic stimuli. The primary cause of the disease is currently unknown.
Local and systemic influence of toxic levels of airborne ozone on the inflammatory response in rats
Authors: Chmielewska-Krzesińska Małgorzata , Wąsowicz Krzysztof 
Published: October 2021

Abstract

Introduction
Ozone is not harmful itself; however, it directly oxidises biomolecules and produces radical-dependent cytotoxicity. Exposure to ozone is by inhalation and therefore the lungs develop the main anti-inflammatory response, while ozone has an indirect impact on the other organs. This study investigated the local and systemic effects of the ozone-associated inflammatory response.

Material and Methods
Three groups each of 5 Wistar Han rats aged 6 months were exposed for 2h to airborne ozone at 0.5 ppm and a fourth identical group were unexposed controls. Sacrifice was at 3h after exposure for control rats and one experimental group and at 24 h and 48 h for the others. Lung and liver samples were evaluated for changes in expression of transforming growth factor beta 1, anti-inflammatory interleukin 10, pro-inflammatory tumour necrosis factor alpha and interleukin 1 beta and two nuclear factor kappa-light-chain-enhancer of B cells subunit genes. Total RNA was isolated from the samples in spin columns and cDNA was synthesised in an RT-PCR. Expression levels were compared to those of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) and analysed statistically.

Results
All variables changed non-linearly over time comparing experimental groups to the control. Conspicuous expression changes in the subunit genes and cytokines were observed in both evaluated organs.

Conclusion
Locally and systemically, inflammation responses to ozone inhalation include regulation of certain genes’ expression. The mechanisms are unalike in lungs and liver but ozone exerts a similar effect in both organs. A broader range of variables influential on ozone response should be studied in the future.
The Salt of the Earth or the Murderess? The Problem of Femininity in the Novels of Agatha Christie
Authors: Baučeková Silvia Rosivalová 
Published: October 2021

Abstract
Agatha Christie’s outlook on gender, as depicted in her novels, has been described as conservative or even criticised as anti-feminist. However, more recently, a growing number of feminist scholars (Alison Light, Susan Rowland, Merja Makinen) have begun to oppose this view and instead argue that Christie’s approach to the various social phenomena depicted in her novels, including gender, is more nuanced and ambiguous than previously assumed. This paper explores the role of domesticity in general, and of food, eating and cooking in particular, in constructing such ambiguous portrayal of femininity in three of Agatha Christie’s detective novels: Cards on the Table (1936), The Hollow (1946), and 4.50 from Paddington (1957). The novels depict three groups of female characters possessing varying degrees of power and independence: the salt of the earth, i.e., the conservative homemaker, the eccentric, and the murderess. It is the aim of this paper to demonstrate that, paradoxically, it is o en through these female characters’ roles within the domestic setting and their engagement with food that they are able to overcome the limitations imposed on them by patriarchal society and achieve a certain level of autonomy within it.

Abstract

Introduction. Breast cancer is the most common malignant neoplasm among women in Poland. Many factors, both non-modifiable and modifiable, are involved in the development of this cancer, so it is important that women know the risk factors and the principles of cancer prevention. Numerous studies show that the knowledge of women in this area is small.

Aim. Determining the state of knowledge about breast cancer of young women in Poland, comparing the analysis of social awareness on this subject with previous research, and identifying the most important preventive measures in this area.

Material and methods. An anonymous questionnaire survey was conducted in electronic form among women aged 16-25 from all over Poland. The study was carried out using a proprietary questionnaire (Google form) completed online. The questionnaire contained closed questions verifying the knowledge of the topic under study and a certificate. The following computer programs were used for statistical analysis of data: Statistica and Microsoft Excel.

Results. Less than a third of women knows the typical age at which breast cancer develops and is aware of the relationship between the use of oral hormonal contraceptives and the development of this cancer. Few of the respondents are able to correctly identify the risk factors for breast cancer, practically every tenth respondent knows the principles of breast cancer prevention, and nearly one third of them correctly indicated its symptoms.

Conclusions. There are gaps in the knowledge of young women about breast cancer that need to be filled. Education in the field of breast self-examination and risk factors for breast cancer development is a priority, which in the future may contribute to increasing the detection of breast changes and reducing the number of breast cancer cases.

Authors: Castaño Ramírez Sandra Milena , Baena Múnera Brian 
Published: October 2021

El propósito del artículo es determinar la asociación entre inteligencia emocional, riesgo de depresión y condiciones sociodemográficas en estudiantes de psicología. Se evalúa con la escala de inteligencia emocional percibida (TMMS-24) y el inventario de depresión de Beck II (BDI-II) a 307 estudiantes (245 mujeres y 62 hombres) de psicología de la Institución Universitaria de Envigado, los cuales cumplen la mayoría de edad. Los resultados obtenidos permiten identificar que los estudiantes con edades comprendidas entre los 18 y los 24 años presentan una poca claridad emocional en comparación con los participantes mayores de 35 años; dichos resultados sugieren que los jóvenes y los jóvenes adultos poseen un mayor riesgo de adquirir depresión que los de mayor edad. Además, se evidencia que, según el sexo, la regulación de las emociones podría variar. También se halla que existe menor riesgo de depresión para quienes tienen pareja sentimental en comparación con quienes no la tienen. Se encuentra que el riesgo a desarrollar depresión implica, entre muchas otras características, sentir y expresar las emociones percibidas adecuadamente. Los participantes de la muestra con riesgo de depresión prestan mucha atención a sus emociones y las expresan de una manera adecuada; sin embargo, tienen poca capacidad para comprenderlas y regularlas.

Published: October 2021

The objective in this study is to examine empirically changes in the level of conservatism of corporate accounting information in Indonesia as a result of the use of Financial Accounting Standards (IFRS) adopted by IFRS (International Financial Reporting Standards). Conservatism was measured using the Market-to-Book bias component model (Beaver and Ryan, 2000). This study uses the Financial Statement data from 178 companies, 2007 to 2016, listed on the Indonesia Stock Exchange. Using multiple regression models that place accounting conservatism as a dependent variable while IFRS adoption, managerial ownership, institutional ownership, and public ownership as independent variables, this study proves that IFRS adoption does not affect the level of conservatism of accounting information. The size of the firm (size) and the composition of debt (leverage) is a control variable that participates in controlling the model of this study.Â Keywords: IFRS adoption, conservatism of accounting information.
