Due to their remarkable magnetic properties, such as a high maximum energy product, high remanence, and high coercivity, NdFeB magnets are used in a variety of technological applications. Because of their very limited recycling, high numbers of spent NdFeB magnets are widely available in the market. In addition to China’s monopoly on the supply of most rare earth elements, there is a need for the recovery of these critical metals, as their high import price poses an economic and environmental challenge for manufacturers. This paper proposes a pyrometallurgical recycling method for end-of-life NdFeB magnets by oxidizing them in air as first required step. The main goal of this method is to oxidize rare earth elements from NdFeB magnets in order to prepare them for the carbothermic reduction. The experimental conditions, such as the oxidation temperature and time, were studied in order to establish the phase transformation during oxidation using the Factsage Database and experimental conditions. Our thermogravimetric analysis TGA analysis revealed an increased sample mass by 35% between room temperature and 1100 °C, which is very close to the total calculated theoretical value of oxygen (36.8% for all elements, and only 3.6% for rare earth elements REE), confirming the complete oxidation of the material. The obtained quantitative analysis of the oxidation product, in (%), demonstrated values of 53.41 Fe2O3, 10.37 Fe3O4; 16.45 NdFeO3; 0.45 Nd2O3, 1.28 Dy2O3, 1.07 Pr2O3, and 5.22 α-Fe.

In this article we consider the applicability of distance education on the elementary level from parents’ perspectives and present the limitations stemming from the degree of support that students in elementary education need from their parents. The dilemmas regarding the possible levels of students’ development of independence and self-orientation, and the parents’ roles are highlighted. We believe that due to these limitations, distance learning has some of the characteristics of home-schooling. The subject of the research in the empirical part of this study focused on parents’ attitudes. Parental attitudes, based on a previously established multi-factor model, become clear from the parents’ experiences (Kolak, Markić & Horvat, 2020) where factors regarding the demands of teaching and the competence of parents as substitute teachers, were separated. Parents’ characteristics (e.g., gender, age, educational status and involvement) were found to influence their attitudes. The results of the research indicate the importance of parents in distance learning during the pandemic which adds a new and more significant role in the educational process of their children.

Introduction: Bilateral ectopic pregnancy is a very rare condition which occurs in 1/725 - 1/1580 ectopic pregnancies, most commonly after induced assisted reproductive techniques. Aim: To present the case of spontaneous bilateral tubal pregnancy, and the problem of insufficiency of available diagnostic methods, which causes that an accurate diagnosis can mostly be made intraoperatively. Case Report: A 37-year-old female, nulliparous, comes at the Clinic of Gynecology and Obstetrics of CCUS, complains of intense suprapubic pain, and difficulty urinating. The expected menstruation was absent for more than 2 weeks. The Grav index test was positive. Beta hCG values were 6312 IU/L. On examination, the patient was extremely pale, hypotensive, gave the impression of hemorrhagic shock, and the abdomen was diffusely palpably painful. After emergency TV ultrasound, then ultrasound and CT of the abdomen and small pelvis, which indicate a moderate amount of thicker fluid in the abdomen and small pelvis in terms of hemoperitoneum and with the left contour of the uterus an oval zone most likely to correspond to ectopic pregnancy, an indication for emergency surgery was made. A laparotomy was performed, and partly liquid and partly coagulated blood was found in the abdomen. The left tube in the isthmic part was ruptured with active bleeding. Right Fallopian tube was pathologically changed, livid, with visible suspicious pregnancy in the ampullary part. Bilateral salpingectomy was performed, and samples are sent for PHD analysis that shows the presence of chorionic villi in both tubes. Conclusion: When ectopic pregnancy is suspected, the possibility of bilateral tubal pregnancy should always be kept in mind, especially in cases accompanied by acute pelvic pain with signs of hemorrhagic shock

Introduction: Musculoskeletal disorders (MSDs) imply damage to muscular or skeletal systems, which usually develop due to strenuous, repetitive activity, or an inflammation process. The therapy with capacitive and resistive electronic transfer (CRet) and high-intensity laser therapy (HILT) have mainly been applied for pain relief in these conditions. This paper aims to provide an overview of the efficient results of CRet therapy and HILT in managing pain associated with musculoskeletal disorders found in the available literature. Methods: Articles related to musculoskeletal disorders were searched through electronic databases, such as PubMed, Web of Knowledge, Lilacs, Cochrane, Research Gate, and available website search tools. After excluding records that are not clinical trials and studies (such as review articles, patient information, and Ph.D. papers) and articles which did not deal with pain in musculoskeletal disorders, 61 articles met our criteria and were included in the overview. Results: By reviewing the selected articles related to CRet therapy and HILT effects on pain in musculoskeletal disorders, it was found that both therapies have a favorable effect on pain reduction. Conclusion: The selected papers showed that both therapies are powerful tools for pain reduction. Although there are no specific protocols, including the number and frequency of therapies applied and other parameters, in both therapy modalities, pain alleviation occurs during or immediately after a therapy cycle application.

The Dinaride Ophiolite Belt formed from the Jurassic part of the Neotethys. The investigated Ozren ophiolite complex in Bosnia and Herzegovina consists of peridotites, plagioclase peridotites, plagiogranites, troctolites and other gabbroic rocks, and fewer basalts. Lherzolites and harzburgites contain corroded ortho- and clinopyroxene1 porphyroclasts enclosed in the olivine matrix. The boundaries between olivine aggregates and pyroxene1 and spinel1 are infilled by medium-grained undeformed aggregates of clinopyroxene2, less orthopyroxene2, spinel2, and often clinopyroxene3-spinel3 symplectites. These textures indicate the final crystallization of peridotite in subsolidus conditions. Partial dissolution of deformed pyroxene1 porphyroclasts and coarse-grained spinel1 most likely occurred due to their reaction with the rest melt present in the grain boundaries. The Al decrease from pyroxene1 to pyroxene2 and 3, or the Cr decrease and Al increase from spinel1 to spinel2 and 3 is characteristic. Peridotites are associated with inferred remnants of a gabbro-dolerite layer, whereas basalts and radiolarites occur as rare dm-size fragments in an ophiolitic breccia. Troctolites display interstitial crystallization of plagioclase, clinopyroxene, less Na-Ti-rich amphiboles, and phlogopite in the olivine-spinel matrix, indicating the replacive character of impregnating melt within the dunite layers. Clinopyroxene-plagioclase-ilmenite-±amphibole gabbroic and fewer basaltic dykes in peridotites formed due to subridge extension, mantle thinning, and the deeper mantle melting. Iron-enriched olivines occur in the peridotite-dyke interfaces and troctolites. Hydrated ultramafics and mafics contain amphiboles, biotite, phlogopite, clinozoisite, epidote, and chlorite aggregates. Estimated magmatic to subsolidus T from peridotite two-pyroxene thermometry are 1000–850 °C, for the spinel facies. Ca-in-orthopyroxene1 thermometry provided T of 1028–1068 °C, and Ca-in-orthopyroxene2 thermometry gave 909–961 °C at estimated P of 1.1–0.9 GPa. However, the gabbroic dyke magmatic crystallization T was constrained to 1200–1100 °C at P of 0.45–0.15 GPa by single clinopyroxene thermobarometry. The obtained P–T conditions constrained the deeper mantle environment for the formation of peridotites than troctolites and crosscutting dykes. The ophiolitic thrust-sheet hanging wall conditions in an obduction-related accretionary wedge were estimated from amphibolites at 620 °C and 0.85 GPa by Ti-in-amphibole thermometry and amphibole-plagioclase thermobarometry. 300 °C and 0.5 GPa were determined from an exhumation shear zone using a combination of chlorite thermometry and Si-in-phengite barometry.

Este artigo investiga como o idoso está contemplado como sujeito de direitos na Convenção Interamericana sobre a Proteção dos Direitos Humanos dos Idosos e objetiva compreender a maneira como as diretrizes internacionais têm tratado a proteção dos direitos humanos na velhice. Foi realizada uma pesquisa documental quanti-qualitativa que analisa o conteúdo da Convenção Interamericana de forma exploratória e descritiva. Verificou-se que a Convenção rechaça a homogeneização e os estereótipos da velhice, sendo fortalecedora do reconhecimento da alteridade e observou-se que o idoso é contemplado como sujeito de direitos que merece proteção e cuidado, não sendo encarado como sinônimo de vulnerabilidade.

Globalization in the field of industry is fostering the need for cognitive production systems. To implement modern concepts that enable tools and systems for such a cognitive production system, several challenges on the shop floor level must first be resolved. This paper discusses the implementation of selected cognitive technologies on a real industrial case-study of a construction machine manufacturer. The partner company works on the concept of mass customization but utilizes manual labour for the high-variety assembly stations or lines. Sensing and guidance devices are used to provide information to the worker and also retrieve and monitor the working, with respecting data privacy policies. Next, a specified process of data contextualization, visual analytics, and causal discovery is used to extract useful information from the retrieved data via sensors. Communications and safety systems are explained further to complete the loop of implementation of cognitive entities on a manual assembly line. This deepened involvement of cognitive technologies are human-centered, rather than automated systems. The explained cognitive technologies enhance human interaction with the processes and ease the production methods. These concepts form a quintessential vision for an effective assembly line. This paper revolutionizes the existing industry 4.0 with an even-intensified human–machine interaction and moving towards cognitivity.

Positive practice environments (PPEs) support the recruitment and retention of employees, enable the delivery of high-quality work outcomes, and benefit society as a whole. It is necessary to provide equal rights, obligations, equal treatment, and opportunities for all genders according to their needs to achieve gender equity and PPEs in workplaces. FIP developed the FIPWiSE (the FIP women in science and education initiative) toolkit for positive practice environments for women in science and education to support and enable them by building on the World Health Professional Alliances (WHPA) PPE campaign. FIP is a founding member of the WHPA and used the toolkit as a basis to describe and identify factors that enable PPEs from a pharmaceutical science and pharmacy education perspective. The toolkit provides a set of possible solutions related to women in science and education for individuals, employers, institutions, and policymakers, as well as real-life examples, perspectives, and good practice implementations and suggestions from women from all around the world.

Standalone hybrid systems based on renewable energy sources may represent a convenient and cost effective option for powering isolated consumers located far from the existing grid. In this study the focus is on particular photovoltaic-wind-diesel-battery systems which supply mobile telephony base stations. In the study, both the consumption of telecommunication electronic equipment and the consumption of cooling devices are taken into account. Nine characteristic locations across Europe with different climatic conditions were selected for comparative techno-economic assessment. For each location, a comprehensive simulation and optimization routine was performed, in order to find the optimal system configuration and the minimum amount of total annualized costs. The obtained results are discussed and some conclusions regarding system sizing at different locations are drawn.

Despite the fact that technology is improving day by day and that the medical devices (MDs) are being constantly upgraded, their malfunction is not a rare occurrence. The aim of this research is to develop an expert system that can predict whether the device will satisfy functional and safety requirements during a regular inspection. This expert system can be seen as part of Industry 4.0 that is revolutionizing medical device management. In order to develop the system, five machine learning algorithms that are representative of each classifier group, were used: (1) Random Forest, (2) Decision Tree, (3) Support Vector Machine, (4) Naive Bayes, (5) k-Nearest Neighbour. The Decision Tree outperformed other classifiers achieving the classification accuracy of 100% with and without attribute selection applied on the dataset. This study showed that machine learning algorithms can be used in order to predict MDs performance and potential failures in order to make the process of maintenance of medical devices more convenient and sophisticated and it is one step in modernizing medical device management systems by utilizing artificial intelligence.

Simple Summary Penalties in judo (shido) have been previously associated with match outcomes and increased the likelihood of being defeated, particularly in heavier weight categories. Each 1-min increase in match duration and further athlete proceeds in competition increases the possibility of receiving a penalty. Penalties have also been associated with the occurrence of injuries, especially with grip fighting and other illegal moves and therefore, have a substantial effect on athletes’ health. The main findings highlighted that the leading penalties in all weight categories for both genders on Judo World Championships (WC) were Non-combativity, Avoid Grip and False Attack. Additionally, a new trend in heavyweight athletes with a lower number of penalties is noted. Abstract Background: This research aimed to compare individual penalties by gender and weight categories in judo from the Judo World Championships (WC): Budapest—2017, Baku—2018, Tokyo—2019 and Budapest—2021 in all individual weight categories for females and males. Methods: Data were collected by notational analysis of 2041 penalty videos for females and 3473 penalty videos for males (total n = 5514). All individual penalties—Shido 1, 2, 3 and Hansoku Make (direct disqualification) were analysed by the Pearson chi-square test at the level of statistical significance of 5%. Results: Significant differences were noted in the assigned individual penalties between individual categories (p < 0.001) in both genders. The significant difference was contributed mainly by the weight category +78 kg with penalties Non-combativity (5.3) and Avoid Grip (−3.4) in females, while in males it impacted by the +100 kg weight category and the Non-combativity (4.2) and Avoid Grip (−4.0) penalties. For females, the most dominant individual penalties were Non-combativity (41.6%), Avoid Grip (16.2%) and False Attack (15.0%), and were Non-combativity (40.3%), Avoid Grip (19.5%) and False Attack (16.4%) for males. The largest number of penalties in females were in −52 kg (16.7%), −57 kg (15.9%) and +78 kg (15.2%) categories, while in males, they were −66 kg (17.2%), −73 kg (16.1%) and −90 kg (15.6%). Conclusions: The findings of this study highlight the leading penalties in all weight categories for both genders on WC to be Non-combativity, Avoid Grip and False Attack. Additionally, a new trend in heavyweight athletes with a lower number of penalties is noted. The obtained results indicate the need to pay more attention to working with competitors of all ages and genders on education to implement tactical variants, forms and means to use penalties to athletes’ advantage, especially after a possible rule change and to lower the occurrence of injuries.
