Introduction: The main aim of this research was to determine whether there are statistically significant correlations between TMG variables and jumping performance. Materials and Methods: Twenty-five healthy and physically active male students (age: 20.84 ± 0.99 years; body height: 179.46 ± 5.91 cm; body weight: 73.88 ± 6.43 kg) of the Faculty of Sport and Physical Education participated in this study. Radial displacement, contraction time and delay time of the m. vastus lateralis were collected to assess muscles’ contractile characteristics using tensiomyography (TMG). Additionally, squat jump and countermovement jump height were recorded using the Optojump system. Results: A very high, negative, statistically significant correlation between both power assessment variables and the radial displacement variable was found; more specifically, the cor-relation between CMJ and radial displacement amounted to r = -.80, p < .01, while for SJ and radial displacement the correlation amounted to r = -.73, p < .01. High, negative, statistically significant correlations (r = -.61 to -.69, p < .01) were achieved among all other variables. Conclusion: TMG parameters could successfully predict jumping performance in the studied sample of male students.
This paper on the lectisternium provides a detailed explanation of this ancient Roman ritual in its role as a key element in the religious and social practices of the Romans. The lectisternium was a ceremony in which the Romans prepared meals for their gods on specially arranged couches, creating the illusion of a divine presence at their feast. This ritual had a profound religious and social dimension, especially during times of crisis such as epidemics and wars, when the Romans prayed to their deities for mercy and protection. The ritual also promoted unity and solidarity among citizens, who opened the doors of their homes and temporarily set aside disagreements, thus bringing a conciliatory character to the ritual. Over time, as social and religious norms changed, the lectisternium gradually lost its significance, and was replaced with new rituals coinciding with the introduction of Christianity. The paper thus provides insight into the importance of this ritual in the context of Roman social and religious life, highlighting its role in shaping Roman social and religious structures.
In this paper, we present the main features of Dynamic Rapidly-exploring Generalized Bur Tree (DRGBT) algorithm, a sampling-based planner for dynamic environments. We provide a detailed time analysis and appropriate scheduling to facilitate a real-time operation. To this end, an extensive analysis is conducted to identify the time-critical routines and their dependence on the number of obstacles. Furthermore, information about the distance to obstacles is used to compute a structure called dynamic expanded bubble of free configuration space, which is then utilized to establish sufficient conditions for a guaranteed safe motion of the robot while satisfying all kinematic constraints. An extensive randomized simulation trial is conducted to compare the proposed algorithm to a competing state-of-the-art method. Finally, an experimental study on a real robot is carried out covering a variety of scenarios including those with human presence. The results show the effectiveness and feasibility of real-time execution of the proposed motion planning algorithm within a typical sensor-based arrangement, using cheap hardware and sequential architecture, without the necessity for GPUs or heavy parallelization.
<p style="text-align: justify;">Shape memory alloys are of great commercial importance from biomedical applications to smart materials. The electrochemical behavior of Cu-Al-Zn alloy in phosphate buffer without and in the presence of amino acid was investigated. Electrochemical researches were performed in a traditional three-electrode system by means of the Tafel extrapolation method. The results showed that the presence of amino acid leads to a decrease in the corrosion rate and the density (values) of the corrosion current, which indicates that the tested inhibitor is efficient.</p>
In the Federation of Bosnia and Herzegovina, through the Law on Internal Trade, it is planned to restrict work on Sundays for most sales facilities. This would apply to the territory of the entity concerned, i.e., 51% of Bosnia and Herzegovina’s territory. Previously, unlike other countries that introduced the same or similar practices, there have been no significant social and political discussions or surveys of the views of workers, employers, and citizens. This paper aims to research the citizens' views of the Federation of Bosnia and Herzegovina on non-working Sundays and thus offer a basis for a better discussion of this issue. A convenience sample of 406 respondents from the Federation of Bosnia and Herzegovina (FB&H) entity was used. Despite the expressed bias on the topic of banning trade on Sundays, the analysis of respondents’ answers regarding the willingness to work on Sundays (with the condition of a second day off some other day and 50% higher wages for working on Sundays) showed that more than half of the respondents support working on Sundays under this condition. The survey results showed that citizens are less inclined to restrict the operation of smaller shops and that the ban on working on Sundays is mainly supported by those who do not work on Sundays.
In their work, dentists, especially those in general dental practice, encounter patients of various ages and with different health conditions. Undoubtedly, the pediatric population is not excluded in this context, and special attention is paid to oncological patients in this population. Malignant diseases require a special approach in the field of dentistry, both through guidelines and preventive measures, as well as in cases where it is necessary to treat conditions or diseases resulting from oncology treatment or the disease itself. Oncological treatment consequences are also visible in the oral cavity, which becomes extremely sensitive during the course of treatment. Children, as oncological patients, can quickly transition from a relatively "healthy state" to a state characterized by significant changes in the oral cavity, which are conditions that are extremely difficult for children to endure. These changes manifest as complications such as oral mucositis, xerostomia, opportunistic infections, dental hypersensitivity, developmental disorders of the jaw structures, and GvHD. For complications during and after chemotherapy, the treatment is symptomatic, involving the implementation of a treatment protocol with clearly defined procedures for each complication, ranging from preventive brushing to the application of medication. Due to the increasing number of pediatric oncological patients, it is the dentist's task to understand the nature of malignant diseases, their basic characteristics, how to prevent the development of oral complications during and after oncological therapy, and how to treat any complications that may arise.
Aim: The aim of the work is to examine the possibility of perception of dental aesthetics and satisfaction with one's own appearance in children of different ages. Materials and methods: In this research, 80 children, aged 3-16 years, participated, none of whom were orthodontic patients. The research consisted of an interview, in which the children were asked questions, and a drawing on the topic of what is a "beautiful and ugly" tooth for them. The questions were designed to reflect children's perception and attitude related to dental aesthetics, as well as satisfaction with their own appearance in the context of dental aesthetics. The drawings and answers were classified according to Piaget's classification of cognitive development, according to the age of the subjects. The questions for the parents were related to the parents' practice related to visits to the dentist and previous caries experience in children. Results: The results of the research showed that all respondents, regardless of gender and age, showed the ability to perceive and express their attitudes regarding the concepts of "beautiful" and "ugly" in the context of dental aesthetics, as well as to express their attitude, knowledge and satisfaction/dissatisfaction with one's own appearance. Conclusion: The research results suggest that the experience of beauty and the feelings associated with dental aesthetics are universal, independent of gender and age. Children have the ability to distinguish what they consider beautiful or ugly, regardless of age, and are able to clearly express attitudes related to satisfaction with their own appearance.
<p style="text-align: justify;">This paper examines the free oscillations of beams, which are essential for preventing resonance in constructions such as bridges, buildings, and other engineering structures. The objective of the study is to evaluate the accuracy of numerical methods by comparing their results with exact solutions for three support conditions: a simply supported beam, a <br />cantilever beam, and a beam fixed at both ends. Exact solutions were presented for all cases. Numerical results for the first three oscillation modes were obtained using ANSYS software and compared to the exact values.</p>
Varvari Ali-pasha was an Ottoman high military commander and governor who flourished during the first half of 17th century. He was native of village Varvara in Bosnia. In this paper, the six archival documents from 1649 were analyzed. The documents were dealing with settling of Paša’s debts. The debts were covered from his inheritance which was excluded from the part of his property confiscated by the State Treasury. His then unsettled debts amounted to 728. 800 akçes. According to the documents, there were Pasha’s six creditors. Five of them were Muslims, one person was Jewish. Mustafa Bey, who was the Pasha’s son, was one of his creditors as well. The documents provide important data on Pasha’s biography, on his family, on his entourage and his household, as well as on the circulation of the European silver coins in the Ottoman Empire during mid of 17th century. Also, they illustrate the socio-economic situation of the Empire in the given period.
The long-standing tradition of real estate registration in Bosnia and Herzegovina has led to the development of several different models for recording real estate information. From the time of the Ottoman Empire to the present day, various authorities have taken charge, each leaving its own mark on the methods of recording real estate and property rights. This paper examines the current state of cadastral and land registry records in the Federation of B&H, as well as the human resources and geodetic equipment available to municipal and city services. The research findings indicate that changes in laws affecting property record-keeping have had significant impacts, resulting in a highly diverse situation regarding real estate records in the Federation of Bosnia and Herzegovina today. This paper provides an accurate overview of the current state of real estate records and offers a solid foundation for making decisions and planning improvements to the management of property records and rights.
Violence is one of the most serious violations of human rights, as evidenced by its complexity and effects. Young people’s violence is one of the most prominent types of violence in our culture. Adolescents who exhibit violent conduct are also more likely to engage in other harmful behaviours, such as chronic lying, drug addiction, reckless driving, high-risk sexually transmitted infections, and chronic absences from school. Emotional difficulties, such as a lack of emotional regulation skills, difficulty resolving conflict, or difficulties coping with feelings of rage, jealousy, or rejection, frequently lead to violence in young people. Since many teen conversations now take place in public on the internet, these difficulties have worsened as social media has grown in popularity. This heightens the teenagers’ feelings of guilt, embarrassment, humiliation, and fear of others’ judgment. Psychologists are shedding light on the matter with their research insights, highlighting the protective and risk factors in violent conduct and prevention strategies and initiatives. This paper attempts to propose a new approach to the prevention and disruption of violence among adolescents that puts an emphasis on developing strengths and abilities rather than standard psychoeducation. Some of the promising strategies that can assist in forecasting teens’ risk for real-world violence include making meaning, developing interpersonal skills, regulating emotions and behaviour, training in communication skills, peer-led programs, digital monitoring, and bystander intervention, which includes peers, parents, and teachers. Not only can these interventions shield teenagers during a crucial developmental stage, but they can also lower their future risk of committing and experiencing intimate partner abuse.
This paper evaluates the impact of a paradigm shift in the monetary system by introducing a model of full reserve banking, focusing on the outcome of separating the generation of money from interest, which can only be achieved by abolishing the system of creating money through debt creation in the banking system. The main thesis argues that the current system, in which private commercial banks create money by issuing loans, results in deposits that mix savings achieved through economic activity with newly created money, leading to economic inefficiency and potential instability because debt and interest are always greater than the economic value created. The 100% sovereign money system corrects this by ensuring that only the central bank has the authority to create money, simplifying the financial landscape and restoring money to its rightful status as a public good and stable unit of measure. The study uses a comparative analysis between the current banking system with fractional reserves and the proposed banking system with 100% sovereign money, which is entirely reserve money. Balance sheet modeling demonstrates the impact of segregating investment and deposit accounts on the books of banks and the central bank. The methodology includes a hypothetical presentation of the balance sheet under the new system, emphasizing the accounting separation of “deposit” and “investment” accounts to end the creation of money by private commercial banks. The balance sheet analysis indicates that adopting a 100% sovereign money system requires state intervention through state deposits into the banking system to achieve the desired level of credit activity.
Introduction: Developmental anomalies and inflammations are common occurrences and are often associated with certain systemic conditions, such as diabetes, allergies, and anemia, as well as with harmful habits. The use of tobacco products and alcohol is frequently linked to changes on the tongue. Objective: This study aims to present the frequency of developmental anomalies and tongue inflammations in the student population of the fourth year at the Faculty of Dentistry in Sarajevo. Materials and Methods: The study was conducted on 50 participants, fourth-year students at the Faculty of Dentistry in Sarajevo. General anamnestic data were collected through a survey, including information on harmful habits such as cigarette smoking, hookah use, and alcohol consumption. A clinical examination of the oral cavity, focusing on the tongue, was performed for each participant, along with vitro-pression, vitro-adhesion tests, and native findings on Candida albicans. Results: The most common developmental anomaly was lingua plicata (4%). The most frequent tongue inflammation in our sample was lingua geographica (14%). Among the 6% of patients with developmental anomalies, 6% had a positive family history. Conclusion: A significant etiological factor is genetic predisposition. In our sample, among 6 participants with developmental anomalies, 6% had a positive family history. The most common etiological factors for the occurrence of developmental abnormalities and tongue inflammations were harmful habits such as cigarette smoking (20%) for over 5 years (14%) and hookah smoking (12%) for over 5 years.
After being presumed extinct, the blind mole rat was rediscovered in Vučedol, Croatia. Phylogenetic analyses using mitochondrial markers (cytochrome b and 16S rRNA) were conducted to classify the population. The results confirmed a distinct separation between the Lesser mole rats (Nannospalax leucodon clade) and Western mole rats (N. monticola clade). Within the N. monticola complex, six lineages were identified, which likely diverged during the Middle to Late Pleistocene. The Vučedol sample belongs to the montanosyrmiensis cytotype subclade, which was also found in Fruška Gora, Serbia. This subclade may represent a new species, showing K2P genetic distances of 4.3% to 5.7% from the "Pannonian Plain" subclade located on both banks of the Danube River. In two Pannonian localities, secondary contacts between populations of both subclades have been documented. One of them is the Kelebia –Subotička peščara population, where a unique subclade "Kelebia" was identified. Populations with montanoserbicus cytotype cluster within two distinct subclades, montanoserbicus A and montanoserbicus B, with K2P distances ranging from 4.6% to 5.3%, indicating potential species status for montanoserbicus A. In the most parsimonious network, montanoserbicus B exhibits a close relationship with the Pannonian Plain sublineage and a single sample from Bosnia and Herzegovina, showing K2P distances of 1.9% to 3.2%, suggesting that they may belong to the same species, N. monticola. Significant divergence between populations in Bosnia and Herzegovina highlights the need for further exploration of local variability and taxonomic status. Detailed analyses with additional markers from more localities are necessary before final species delimitation and taxonomic revision can occur. For now, Nannospalax monticola (Nehring, 1898) remains the sole valid name in the N. monticola complex.
