Published: March 2022

Objectives: This study aimed to assess intra- and inter-examiner reliability of International Caries Detection and Assessment System (ICDAS) and modified epidemiology ICDAS (MOD) code by undergraduate dental students with different clinical experiences. Methods: A total of 150 dental undergraduate students with varying clinical experiences (0, 1 and 2 years of clinical experience) were recruited. Participants received training through a theoretical lecture on ICDAS criteria by an experienced National Benchmark Group (NBG) examiner and underwent e-learning program prior to ICDAS calibration. Visual examination on extracted permanent teeth (N= 45) with different location and stages of caries progression ranging from ICDAS scores 0 to 6, was performed using the ICDAS criteria. The assessments were repeated after one hour. The data were analysed to evaluate inter-examiner and intra-examiner reliability in the form of kappa scores using SPSS 23 Software. Results: Mean kappa values for intra- and inter-examiner reliability for ICDAS code, were between 0.41 to 0.60, and 0.61 to 0.80 respectively. For MOD code, mean kappa values for intra- and inter-examiner reliability were between 0.61 to 0.80. Good intra-examiner agreement (>0.61) was observed in both ICDAS and MOD code for all groups. Conclusion: All students performed similar agreement, therefore, clinical experience within 2 years does not influence the performance of visual inspection in detecting caries using ICDAS. The results of the study shows that ICDAS and modified epidemiology ICDAS codes has good reproducibility and is feasible to be used as a tool in clinical practice as well as patient education.

Physical sporting activities is beneficial for your health. It has to be continuously and constantly performed route in creating positive and healthy lifestyle as it involves self-discipline. It needs a special interest and a positive mindset to attract students to take up sporting activities. The objective of this study is to assess the students’ interest in sports based on several factors among the excellent students. The samples for this study are a group of students (N = 420) comprises of male (n = 210) and female (n = 210) with the age of 16 years old, selected based on simple random sampling. Questionnaire forms were used as a method for data collection. Descriptive and inferential analysis was used to look at the factors influencing students’ sporting attitudes based on demographic data. The result shows that there are four factors highly influencing sporting attitudes. However, only the aspect of value that has significance different from gender p <0.05, where male students are higher than female. Nevertheless, the most significant factor is gender, p<0.05, where male students found to be higher than female. This value aspect is a preliminary consideration of the advantages or disadvantages of sports. Sporting assessment also depends on the effectiveness of teaching by educators who shape the behavior of students to pick up sports. Hsiao (2009) emphasizes the attitude of teachers or lecturers who care about students, know what is being taught, easy to discuss and make teachers and lecturers happy to be with them.
Influence of fertilisation and crop rotation on grain yield and quality of winter wheat (Triticum aestivum L.)
Authors: Babulicová Mária , Gavurníková Soňa 
Published: March 2022

Abstract
At the present time, crop rotations are constantly adapted to economic conditions and one or two main crops are grown in agricultural farms. This has a negative impact on the environment. The optimization of grain yield and quality of winter wheat are dependent not only on the appropriate crop rotation but also on the nitrogen fertilisation. The aim of this study was to examine the effect of crop rotations, fertilisation and preceding crop on grain yield and quality of winter wheat during the years 2015/2016 – 2017/2018. The grain yield of winter wheat after preceding crop pea in crop rotation with 40% proportion of cereals was statistically higher (5.91 t/ha) than in crop rotation with 80% share of cereals (5.55 t/ha). In the treatment with mineral fertilisation and organic manure Veget® incorporation, the grain yield was statistically higher (6.00 t/ha) than in the treatment with mineral fertilisation (5.50 t/ha). According the standard STN 46 1100-2:2018 based on the wet gluten content, the winter wheat grain was classified into the class E by mineral fertilisation + organic manure Veget® in all monitored years. In 2017 the winter wheat grain was categorized into the class P based on wet gluten content in crop rotations with 80% proportion of cereals in the treatment with fertilisers only after preceding crop winter barley.

Abstract
In this manuscript, we have studied the coupled system of Hilfer fractional differential equations with non-local conditions. We have used the Leray-alternative Schauder’s and the Contraction principle to obtain the results on the existence and uniqueness of the solution of the proposed problem in the weighted space of continuous functions. For the defined problem, sufficient conditions have also been developed to determine the Ulam stability of the solution. The key conclusions are well-illustrated with examples.
Case Studies on Finite Element Modeling of Welded Joints
Authors: Heinemann Patrick , Isopescu Dorina , Maxineasa Sebastian George 
Published: March 2022

Abstract
Joints made out of tubular steel members are often used in industrial constructions, like offshore, trusses or tree-shaped columns. The joint area is the weakest point in a truss structure. Beside the normal static behaviour many non-linearities due to the geometry or to the welding process have to take into account. Steel hollow sections are often used. Much research was made on welded nodes so far, but mostly it is valid for limited geometries or load cases. A review of the main aspects in designing welded nodes are given.
The second part is about a study of two aspects. The first aim is to investigate the influence of the joint angle on the resistance of a T-joint made out of Circular-Hollow-Sections or Squared-Hollow-Sections under a tensional load. To archive the most realistic results, the second aspect, a numerical study on the finite element types and the element shape functions will be made.

Published: March 2022

Abstract
Here, we present the latest findings on moth fly (Psychodidae: Diptera) species richness in the Moravskoslezské Beskydy Mts. and Podbeskydská Pahorkatina Uplands, based on both previously published and unpublished data and new samples collected between 2007 and 2020. Two species new to the fauna of the Czech Republic were recorded (Sycorax feuerborni Jung, 1954 and Jungiella (Jungiella) revelica Vaillant, 1972), bringing the total number of moth fly species in the Czech Republic to 180 (Ježek et al. 2021). In addition, five species were recorded for the first time in the area of interest: Trichomyia parvula Szabó, 1960 (second locality in the Czech Republic); Paramormia (Phyllotelmatoscopus) acuta (Krek, 1971) (third record in the Czech Republic); Philosepedon (Philosepedon) perdecorum Omelková & Ježek, 2012 (third locality and fourth record); Pericoma (Pericoma) ljubiniensis Krek, 1969 (second finding and third locality); Tonnoiriella pulchra (Eaton, 1893) (sixth area and first finding in the Czech Carpathians). The finding of Jungiella (Jungiella) valachica (Vaillant, 1963) confirms its historical occurrence in the region. In the latest survey, we collected 108 species from 29 localities, of which 16 are critically endangered, eight endangered and three vulnerable. Nine localities were evaluated as species-rich, i.e. Hluchý 1. (58 species), Vysutý 2. (56), Hluchý 2. (53), Vysutý 4. (49), Skalická Morávka 2. (46), Chladná voda 3. (44), Hluchý 3. (43), Morávka - spring and Obidová 1. (both 42). The total number of moth flies found within the Moravskoslezské Beskydy Mts. and Podbeskydská pahorkatina Uplands now stands at 124 species, representing 68.9 % of total Czech fauna.
Stoneflies (Plecoptera) of the Moravskoslezské Beskydy Mts. and the Podbeskydská pahorkatina Uplands, Czech Republic. I. Systellognatha
Authors: Kroča Jiří 
Published: March 2022

Abstract
Publications up to 2011 record 21 species of stonefly, infraorder Systellognatha, as occurring in the Moravskoslezské Beskydy Mts. and Podbeskydská pahorkatina Uplands; however, seven of these cannot be considered part of the fauna of this area as they probably never occurred there, and one species (Perla abdominalis Burmeister, 1839) was not confirmed, despite being demonstrably recorded in 2000. In the present study, the current stonefly fauna was confirmed at 14 species, belonging to three families and eight genera. The occurrence of Isoperla sudetica (Kolenati, 1859) is published for the first time. Among the most important findings are confirmation of the occurrence of two endangered species (Perla grandis (Rambur, 1841) and Arcynopteryx dichroa (McLachlan, 1872)) and one near threatened species (Isoperla buresi Raušer, 1962). Equally important is confirmation of the occurrence of Perlodes intricatus (Pictet, 1841), based on egg morphology and DNA barcoding.

Методом теории функционала электронной плотности исследована структура кремниевого аналога молекулы CL-20 и предсказана возможность ее димеризации посредством молекулярных мостиков CH2 и SiH2. Установлено, что замена углерода на кремний в каркасе молекулы CL-20 слабо меняет геометрию NNO2 групп. Показано, что реакция димеризации выгодна энергетически и может самопроизвольно протекать при нагревании. Вычислено, что метилен обеспечивает большее энерговыделение в процессе димеризации, чем SiH2.
Structure of the silicon analog of CL-20 molecule was investigated in the framework of density functional theory. The possibilities of its dimerization via the molecular bridges CH2 and SiH2 were also considered. We found that replacement of a carbon by silicon slightly changes the geometry of N-NO2 groups. It was shown that the reaction of dimerization was energetically favorable and could spontaneously take place under heating. According to our calculations, methylene molecular bridge provides higher energy-releasing during the dimerization in comparison with the SiH2.
