The aim of this paper was to analyze the spelling errors of children with dyslexia, in order to determine whether they have a specific pattern of spelling errors or are simply late in acquiring spelling skills. The sample included 30 children with dyslexiaand 30 spelling-level-matched younger children. The research was conducted in the area of Sarajevo Canton and Tuzla Canton in the period from March to May 2022. The results showed that children with dyslexia make similar patterns of errors as spelling-level-matched group. The obtained results show that children with dyslexia in transparent orthography do not have a specific deficit in spelling, but rather delay in acquiring spelling skills. Key words:dyslexia, transparent orthography, spelling errors, specific deficit, delay.

Background: Acute gastroenteritis remains an extremely common problem among the general population. In Western countries, an average person will probably face one or two episodes of gastrointestinal infections every year. Objective: The aim of this study was to compare the efficacy of nifuroxazide and probiotic preparation containing lactic acid bacteria in the treatment of acute diarrheal syndrome. Methods: The study was prospective, comparative study. Patients who suffered from acute infective diarrhoea for ≤72 hours and had ≥3 unformed stools per day, with no administration of antibiotics during 10 days before enrolment were divided into two groups: nifuroxazide group and the lactic acid probiotic group. All patients received therapies four times a day for three days. Data was collected at the baseline visit (before the initiation of the treatment) and two follow-up examinations on the third and seventh day from the treatment start. Results: The study included 61 patients, 36 in nifuroxazide group and 25 in probiotic group. Nifuroxazide group compared to probiotic group showed faster improvement of patients’ condition with lower number of stools three and seven days after therapy start (p=0.001 and p<0.001 respectively) and faster stool consistency normalization. On the seventh day from therapy start medium mushy stool consistency was observed in the majority of patients in nifuroxazide group (n=31, 86%) and only in small number of patients in probiotic group (n=5, 20%). Patients were feeling better and there was a trend of reporting better therapy efficacy in nifuroxazide group. Subjective assessment of therapy tolerability was also better in nifuroxazide group. Compliance to therapy and recommended dietary regime was similar between groups and there were no significant differences between groups regarding age, gender, elevated body temperature, abdominal pain, cramps, nausea and vomiting. Conclusion: Although probiotics are sometimes used in the treatment of acute diarrheal syndrome, nifuroxazide has better efficacy and greater patients’ satisfaction. Nifuroxazide can be recommended as the first choice empirical treatment in adult patients with the acute diarrheal syndrome.

This paper presents geological characteristic of the deposit Kotezi of the Bugojno coal basin. Regional geological researches were conducted from 1983 to 1987, and detailed from 2014 to the end of 2018. After field research and laboratory tests, the analysis and interpretation of the obtained results was carried out. Based on the determined borders of surface distribution and the research results of the coal deposit Kotezi, proved are four coal layers: II bottom, I bottom, main and roof. Coal of the deposit Kotezi belong to the younger coals, soft to medium hard, no luster (matt), brown to black colored, and have brown streak. Their fracture is plate-like and particleboard. He do not have a distinct lignite structure, except in the lower layers. With their general habitus, they resemble younger brown coals, and belong to humic coals which are relatively low in carbonation. Coal deposit Kotezi is the most important deposit in the Bugojno basin, which is very important due to continuity of coal exploitation. Considering the raw material potential and the possibility of expanding the existing raw material base, the Bugojno coal basin has particular importance for the long-term development of lignite exploitation and its use for thermal energy purposes. Key words: the Bugojno coal basin, Kotezi, coal layers, raw material potential.

Despite emails having been a standard technology since the 1970s, they are still indispensable in daily communication and the number of sent emails continues to rise year by year. This technology is not limited to business, it is also used in education, entertainment, or personal correspondence. Emails are also present in the everyday life of children: they are required to join websites, social networks or to participate in school -especially in homeschooling. However, emails are also associated with disadvantages such as spam, phishing, or malware. To engage children in security awareness we developed the DigiSkill platform, which provides interactive educational experiences. It consists of modules such as email or browser simulations, to increase the student’s digital skills. In this research, we evaluated the tool with 52 secondary school students to observe their knowledge on security awareness in the context of email usage and to help gain a better understanding. Therefore, we conducted an in-class evaluation with a tool intervention and related pre- and post-activities. We observed different characteristics in emails that students use for classification and identified common misconceptions. We found that students follow an intensely visual approach, which means the visual representation of an email has a strong impact on the level of suspicion students have. We aim to provide educators with a tool to improve the security awareness skills of their students and to discuss educational possibilities in this field with our research findings.

Wastewater from industrial process of uranium ore mining contains a large amount of this radioactive pollutant. Regarding the advantages of biosorption, it was found that varieties of biomasses such as agricultural waste, algae and fungi are effective for uranium removal. However, there is limited research on cyanobacteria, therefore, cyanobacteria, Anagnostidinema amphibium (CAA) was investigated by batch method for the first time for biosorption of uranium (VI). Optimization of biosorption parameters showed that maximum removal efficiency of 92.91% was reached at pH range of 9-11 with 50 mg of cyanobacteria to 100 mg/L U(VI) initial concentration, at 25 °C within 40 min. Used biosorbent exhibited very good selectivity for U(VI) ions and reusability in IV sorption/desorption cycles. Characterization of CAA surface was performed by FTIR, EDS, EDXRF and SEM analysis and it has shown various functional groups (CONH, COOH, OH, PO alkyl group) and that it is very rich in elements such as iron, potassium and calcium. In binary systems, contained of U(VI) and selected ions, CAA exhibits very good selectivity towards U(VI) ions. Kinetic data revealed the best accordance of experimental data with the pseudo-second-order model, and isotherms data agreed with Freundlich model. Thermodynamic data implied that U(VI) biosorption process by A. amphibium exhibited spontaneity and modelling of the investigated process showed that the adsorption of uranium ions occurs mainly via peptidoglycan carboxyl groups. Overall results show that these cyanobacteria with a maximum sorption capacity of 324.94 mg/g have great potential for the processing of wastewater polluted with uranium (VI).

Abstract Cathodic protection system is commonly employed approach for the protection of the metallic infrastructure placed in electrolyte against corrosion. Adequate design of the cathodic protection system requires the determination of electrical potential and current density distribution on the protected object surface that meets the defined criteria. In this paper, the application of the direct boundary element method in conjunction with Newton-Raphson method was considered for the calculation of the electric potential and current density distribution on the surface of the cathodically protected underground object. The considered method was applied on the sacrificial anode cathodic protection system of the underground pipeline. The non-linear boundary conditions of the electrode surfaces of the cathodic protection system are taken into account. The method was used to determine the current density and electric potential distribution on the external wall of the protected pipeline.

Using the CO molecule as target, we investigate high-order harmonic generation by a bichromatic elliptically polarized laser field. This field consists of two elliptically polarized components with the commensurable frequencies and mutually orthogonal semi-major axes. Both odd and even harmonics are emitted and their ellipticity can be large depending on the values of the laser-field parameters. It is often the case that the ellipticity of subsequent odd and even harmonics is substantially different so that, in order to produce a series of high-order harmonics with similar ellipticity, it is beneficial if the emission of odd or even harmonics is suppressed. In this paper we explore how this can be achieved using the ellipticity of the laser-field components and the relative phase as control parameters. For some values of these parameters it is possible to produce a comb of odd or even harmonics with similar ellipticity. These harmonics can later be employed for various applications the example of which is the generation of an elliptically polarized attosecond pulse train.

Industry 4.0 has a significant impact on the automation of production processes, by causing numerous changes in three segments: companies, technology and workers. Developed countries worldwide have their own strategies on Industry 4.0, which offer guidelines on its implementation in production processes, with the aim of their complete flexible automation. The core technologies on which Industry 4.0 rests have led to a complete transformation in production processes, especially in the automotive industry. The basic technology of Industry 4.0 is robot technology, i.e., the implementation of industrial and service robots in production processes. The paper provides an analysis of the implementation of industrial robots and service robots in the automation of production processes in the automotive industry with a focus on China. The analysis of the automation of production processes of the automobile industry in China was carried out for two reasons. The first is that China has a growing middle-class population, so demographic trends are encouraging the growing demand for certain products, such as cars. Another reason is that in China (as in Japan, Russia and Western Europe) the average age of factory workers is increasing (the labor force is older), thus the performance of certain tasks becomes more difficult so greater efficiency is not achieved. The paper analyzes vehicle production in China, as well as the readiness of production processes in the automotive industry for the implementation of Industry 4.0.

Abstract The global Covid-19 pandemic led to the turn toward online learning and the need to adapt to new ways of English foreign language (EFL) teaching. This mixed-methods research aimed to examine teacher attitudes, well-being, and coping strategies related to online EFL teaching. The results indicated that Croatian EFL teachers had a positive attitude toward online teaching and acknowledged the importance of being digitally competent. EFL teachers were unsure about their ability to deal with online teaching and indicated their need to improve their IT skills. They revealed more negative than positive responses regarding their well-being and showed that they tried to actively cope during the pandemic. Results also showed better coping strategies among female teachers.

Abstract Frequent changes in fiscal policies are the main cause of credit risk. To prevent households from increasing their non-performing loans, the government can use various policies and instruments. One of these tools is tax regulations, with a particular focus on the value-added tax. This paper examines whether tax policies have affected non-performing household loans in Turkey over the period from 2017 to 2021. To acquire meaningful empirical results, the Autoregressive Distributed Lag (ARDL) cointegration model have been applied. The results of analysis indicated that the effect of tax regulations on non-performing household loans is quite strong. It can be demonstrated that the strength of the income effect generated by tax cuts might be robust.

The research relates to determining the dependence of the strength and hardness, as well as the pH factor and solubility in water, of pellets made based on dolomite powder on the type and concentration of the binder. During the research, the technological parameters of the pelletizing device (speed and inclination of the disk, dosing speed of powder and binder suspension, and mixing time) were kept constant. Variations were made in the concentration of starch and molasses binder at values of 1.0, 2.5, and 4.0% and the control sample of 2.0 %. The purpose of pellets made of dolomite powder is to correct the pH factor of agricultural soil. The obtained results indicate that the production of pellets for the stated purpose requires an optimal choice of binder and its concentration due to the influence on the qualitative indicators of the pellet itself from dolomite powder. The research results are a partial extract of the Study: “Investigation of the optimal technology for the production of dolomite pellets from the “Očura” deposit for agriculture, Phase I”. Keywords: pellet, agriculture, binder concentration, strength, hardness, pH of pellets.

Conducting safety simulations in various simulators, such as the Gazebo simulator, became a very popular means of testing vehicles against potential safety risks (i.e. crashes). However, this was not the case with security testing. Performing security testing in a simulator is very difficult because security attacks are performed on a different abstraction level. In addition, the attacks themselves are becoming more sophisticated, which directly contributes to the difficulty of executing them in a simulator. In this paper, we attempt to tackle the aforementioned gap by investigating possible attacks that can be simulated, and then performing their simulations. The presented approach shows that attacks targeting the LiDAR and GPS components of unmanned aerial vehicles can be simulated. This is achieved by exploiting vulnerabilities of the ROS and MAVLink protocol and injecting malicious processes into an application. As a result, messages with arbitrary values can be spoofed to the corresponding topics, which allows attackers to update relevant parameters and cause a potential crash of a vehicle. This was tested in multiple scenarios, thereby proving that it is indeed possible to simulate certain attack types, such as spoofing and jamming.
