We present an open-source web tool for quality control of distributed imaging studies. To minimize the amount of human time and attention spent reviewing the images, we created a neural network to provide an automatic assessment. This steers reviewers’ attention to potentially problematic cases, reducing the likelihood of missing image quality issues. We test our approach using 5-fold cross validation on a set of 5217 magnetic resonance images.

This paper presents a comprehensive treatment of the complex motion control systems in the the Sliding Mode Control (SMC) framework. The single and multi degrees of freedom (DOF) plants and applications to haptics and functionally related systems are discussed. The paper concentrates on presenting the designs that are easy to apply and tune. The proposed algorithms are based on the application of the equivalent control observer and the convergence term that guaranty stability of the closed loop in a Lyapunov sense and enforces the sliding mode on selected manifolds. Presented SMC design leads to a solution that easily could be modified to include majority of the algorithms presented in the literature.

The paper points out the leading role of the HR department in crisis situations, with special emphasis on the crisis caused by the COVID-19 pandemic, which affected the whole world in early 2020. Regardless of the intensity and form in which they occur, crises threaten the functioning and survival of organizations. The HR department is an important factor in the successful functioning of organizations and, in a period of crisis, this department takes a leading role in the process of crisis management and subsequent recovery. During COVID-19 pandemic, the HR department of every organization had to confront new challenges in order to protect the health of employees, while ensuring the normal functioning of organizations. In order to find out how this department dealt with crisis that occurred, empirical research with a specially designed questionnaire was conducted and filled in by 108 respondents from Serbia, Bosnia and Herzegovina, and Croatia in 2020. The research results showed that HR department has taken a leading role in preserving the health and safety of employees, as well as in the process of adapting organizations to function in crisis conditions. According to results, the key activities carried out by the HR department in organizations are work from home (wherever the nature of the work allowed), flexible working hours, reorganization of the working space to achieve the required physical distance between employees, improved hygiene measures, etc. In addition, the research results showed that, during the global COVID-19 pandemic, the HR departments took an active role in providing psychological assistance to employees to adapt to new conditions and ways of working.

Selective separation and removal of a metal species from complex matrices of other species is of critical importance in separation sciences and especially in industrial processes. The selectivity and efficiency of Pb(II) ion removal from an aqueous solution in the presence of Ni(II), Zn(II), Co(II), Cu(II), and Cd(II) ions as competing ions in a multi-component aqueous source phase through bulk liquid membrane system were investigated. The influence of the palmitic and oleic acid as supporting surfactants in the membrane phase on the removal of Pb(II) ions was also analyzed. Dicyclohexano-18-crown-6 dissolved in chloroform, proved to be a selective and efficient carrier for Pb(II) ions. In the optimized procedure, 3 hours of equilibrium time was required to achieve the maximum removal efficiency. It was found, that removal of Pb(II) ions was achieved without significant reduction in the efficiency compared to the liquid membrane transport of a single-component system. None of these cations interfered with Pb(II) removal. The presence of the oleic and palmitic acid in the membrane phase increase the content of Pb(II) removed to the receiving phase. In optimal transport conditions, more than 97% efficiencies for the removal of Pb(II) were obtained for a system supported by oleic acid. The excellent efficiency and high degree of selectivity for the Pb(II) ion removal by the proposed BLM system, reveals its potential application for the selective removal, concentration, and purification of lead ions from its different mixtures.

Various plants have been used in traditional medicine for thousands of years as natural medicines with therapeutic and other pharmacologic effects. Bioactive compounds found in plants, such as flavonoids, trace minerals, essential oils, phenols, glycosides, alkaloids, and tannins, can affect microbial growth, reproduction, and essential cell functions. Plants of the Amaranthaceae family have a broad range of bioactive phytochemical constituents, which provide a variety of medicinal benefits. This review article discusses the characteristics of Amaranthaceae plants that may indicate their use as medicinal plants, especially against infectious diseases. According to the literature, Amaranthaceae plants contain considerable levels of bioactive compounds that make them effective in traditional medicine, even though their impact on numerous microbes has yet to be examined.

Background: Alternative The topic of this article is the development of pharmacy in the Middle Ages. Objective: The aim of this paper is to bring readers closer to the development and importance of pharmacy and health activities in general of this century. Methods: This is sistematic review of the published papers about historical facts about development pharmacy in Bosnia and Herzegovina in the past. Results and Discusion: There are few documents that speak and testify about health and hygiene data and opportunities in Bosnia and Herzegovina from the Middle Ages and the time of the independent Bosnian state, because very little was written and mostly knowledge was transmitted by narrative. Bosnia, as an independent state, was first mentioned in the Charter of Kulin Ban in the 12th century. The Charter was sent to the Republic of Dubrovnik and provided safe passage for merchants through Bosnia and tax exemption. The Republic of Dubrovnik also had many influences on the development of all social conditions, including medicine and pharmacy. Doctors and pharmacists were able to come to Bosnia unhindered and engage in treatment and the sale of medicines, without having to fear whether they would pay taxes to the state or be robbed. Conclusion: Until Bosnia came under Ottoman influence, treatment in Bosnia was rather primitive, the number of pharmacies and health facilities was minimal, and hygienic conditions were rather poor. Folk medicine and spells were mainly practiced, which were passed down from generation to generation, by narrative tradition. Only with the arrival of the Ottomans, hospitals and pharmacies began to open, and the health care system was better regulated.
