Three Dimensional Formation Control of Unmanned Aerial Vehicles in Obstacle Environments
Authors: BEKMEZ Abdülmelik , ARAM Kadir
Published: January 2024

Today, the use of small unmanned aerial vehicles (UAVs) has increased due to technological advances. There has been an interest in using multiple UAVs instead of a single UAV to accomplish a given mission. This is because there are many scenarios where the capabilities of a single UAV are inadequate due to certain constraints (battery capacity, time in the air). For this reason, swarm UAV studies have increased. A swarm UAV consists of a large number of UAVs cooperating to accomplish a specific mission.

This study shows three-dimensional formation control of a swarm UAV system in an obstacle environment. A centralized control architecture is used in this process. All task assignments are made from a centralized system. The Artificial potential fields method creates the formation at the target point by avoiding obstacles. The study was carried out using the Robot Operating System (ROS). The methods were tested in Webots simulation environment. Crazyflie robots were used in the experiments.

In the simulation environment, square, star and v formations were first tested in two dimensions. Then, as an example of three-dimensional formation, the cubic and pyramid formations were created and observed.
The Role of Parents’ Mores on Their Intentions to Enroll Their Children in a School-based Telemedicine Program
Authors:   Drexel University, Ghashami Farnaz , Gantz Christopher ,   Takeda Pharmaceuticals, Gefen David ,   Drexel University
Published: January 2024

Hospitals providing nurse-run school telemedicine programs can improve children’s access to healthcare services by delivering such services on school premises. Despite this potential, the enrollment in such programs by parents falls short of expectations because of parents’ hesitation to allow their children to receive such telemedicine healthcare services. This study investigates some aspects of the role of parents’ perception of contributing to a good cause (i.e., personal mores), on their intentions to enroll their children in such a telemedicine program. Surveying parents about such a new telemedicine service that is being deployed in their school district shows that parents’ personal mores are associated with increased intentions over and above its expected time-flexibility advantages. Surprisingly, trust-increased intentions were fully mediated by those mores. Practical and theoretical implications are discussed, especially the idea that doing good to others may be another reason why people adopt telemedicine, suggesting another reason beyond the utilitarian, rational, and social processes that are portrayed in previous research.

The stressed-strain state and limit equilibrium of shallow spherical shell weakened by two cross-cutting meridional collinear cracks is studied in the two-dimensional formulation. The crack closure caused by bending deformation was taken into account based on the model of the crack edges contact along a line in one of the face surfaces of the shell. The boundary problem for equations of classical shell theory with interrelated conditions along the line of the cracks is formulated within the framework of such model. Singular integral equation for the unknown jump of normal rotation angle on the cracks edges has been elaborated. Based on numerical solutions of singular integral equation the stressed-strain state and limit equilibrium of the spherical shell depending on the parameters of shell curvature and distance between cracks are investigated. Using the local and integral through-the-thickness energy failure criteria of linear mechanics of fracture, the upper and lower values of limit load were established. It was found that the upper estimate of the limit load according to the integral criterion is approximately twice the magnitude of the lower estimate according to the local criterion.

The plane strain problem for the bimaterial space consisting of two piezoelectromagnetic half-spaces with a finite set of cracks along the material interface is considered. It is assumed that the edges of the crack are electrically and magnetically permeable, and a mixed mechanical load and electric and magnetic fields can be set at infinity. The presentations of electro-magneto-mechanical quantities through a piecewise analytical vector function are constructed with the use of constitutive equations for piezoelectromagnetic materials. By means of these presentations the problem of linear relationship is formulated and solved analytically. Using the obtained solution, all the necessary mechanical, electrical, and magnetic components along the material interface as well as the energy release rate for all crack tips are found analytically. The asymptotic presentations of all fields around the crack tips and the crack closure integral method were used. Numerical results are obtained for different loads, location of the cracks, their number and lengths. A significant increase in energy release rates was demonstrated because of cracks converge, especially for the tips located closest to each other.
An effective numerical method for solving the Richards-Klute equation with tracking of full saturated zone
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Kolesnykov V. A.
Published: January 2024

The article presents modifications for numerical methods for modeling of mass transfer process in porous medium with full saturated zone tracking. The goal of the article is to increase computational efficiency of finding an approximate solution process using division of the area into the two non-intersecting parts: unsaturated zone and zone with full saturation. Numerical methods for solving the one-dimensional Richards-Klute equation with tracking of the full saturated zone have been developed. The cases of monotonic solution and solution with general properties of Richards-Klute equation were considered. A modification of the full saturated zone tracking process using a doubly connected edge list structure have been developed for two-dimensional case. Efficiency increase estimation is proven for one- and two-dimensional cases using probability distibution for a measure of the full saturated zone. A comparative analysis of the proposed modifications was carried out. The results of numerical experiments coincide with the estimates predicted by theory.
Solution of the traveling salesman problem based on the annealing method with the fuzziness of the time perception
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Rets V. O.
Published: January 2024

This paper investigates the use of fuzzy numbers and the annealing method to improve the results of the traveling salesman problem (TSP) by more accurately representing real-world circumstances, where the value of the objective function represents the subjective perception of the length of the time interval required to travel between cities. TSP is a classic combinatorial optimization problem that involves finding the shortest route between a set of cities. Fuzzy numbers are used to model input inaccuracy and uncertainty, as they allow for a more detailed representation of real-world constraints and factors that may affect the problem. The annealing method is used to optimize the TSP solution by gradually decreasing the temperature of the system, which allows exploring different solutions and avoiding getting stuck in local minima. To demonstrate the effectiveness of this approach, a Python program was developed that was used to compare the results of the TSP problem using crisp and fuzzy numbers using the annealing method. The results show that the use of fuzzy numbers, particularly triangular and parabolic, with the annealing method leads to a significant improvement in the results of the TSP problem compared to the use of crisp numbers, assuming a model is called realistic if it has possible deviations from the expected fixed mean. Computational results of the program are presented and analyzed, demonstrating the potential of this approach for real-world optimization problems involving imprecise or uncertain data and which can be particularly applied to the optimization of processes with subjective time perception.

Published: January 2024

The article is devoted to the analysis of tasks for building a writing assistant, one of the most prominent fields of natural language processing and artificial intelligence in general. Specifically, we explore monolingual local sequence transduction tasks: grammatical and spelling errors correction, text simplification, paraphrase generation. To give a better understanding of the considered tasks, we show examples of expected rewrites. Then we take a deep look at such key aspects as existing publicly available datasets and their training splits, quality metrics for high quality evaluation, and modern solutions based primarily on neural networks. For each task, we analyze its main peculiarities and how they influence the state-of-the-art models. Eventually, we investigate the most eloquent shared features for the whole group of tasks in general and for approaches that provide solutions to them.
Some legal aspects of ensuring the psychological safety of children in need of state assistance
Authors: Gorbachev A.N. , Zholnerova L.K.
Published: January 2024

The article is devoted to the analysis of the legal aspects of ensuring the psychological safety of those children who need state assistance. The article discusses the issues of systematization of the conceptual apparatus of legislation that determines the legal status of such a category of minors in need of state assistance, such as children in difficult life situations, including children left without parental care. Particular attention is paid to the legal status of children in a socially dangerous situation. The thesis is substantiated that the legal mechanism for ensuring the psychological safety of children in need of state assistance is fundamentally different from a similar mechanism addressed to children who managed to avoid the consequences of parental deprivation in their life. The current Russian legislation, which defines the legal basis for ensuring the psychological safety of various categories of children who need state assistance, is examined, and ways to improve it are proposed.

Published: January 2024

The review article presents a discussion of some topical issues of standardization of activities to prepare orphans and children without parental care for independent living and their support after graduation from various forms of education. The focus is on children of the normotypical category and children with “special needs” – with limited health and (or) disabilities, with mental development disorders, with socially significant diseases, who need to develop adherence to taking medication. The structure and content of the standards are considered, the forms and methods of preparing students for independent life and accompanying graduates are illustrated, including an analysis of organizational resources and evaluation criteria. The speakers noted the need to focus on developing skills that will be in demand in a new place of life after adulthood, as well as developing independence in performing daily life activities for special categories of graduates. The results of testing the tools for socio-psychological examination of pupils and graduates in various forms of living conditions, and certain effective practices (mentoring, training apartments, project activities, etc.) that contribute to the implementation of the provisions of the standard were presented.

Effect of different positioning before, during and after surgery on pressure injury: a randomized controlled trial protocol
Authors: Guler Bedia , Gurkan Aysel
Published: January 2024

Background: Patients undergoing surgery are at risk of developing pressure injuries because they remain immobile and in a fixed position on the operating table for a long time under anesthesia. Prevention of surgery-induced pressure injuries is the best strategy and requires risk assessment and timely implementation of preventive interventions. This trial aims to evaluate the effect of positioning in a different position pre-operatively and post-operatively than the position adopted during surgery on pressure injuries.
Methods: This trial was designed as a prospective randomized controlled study. Participants meeting the inclusion criteria will be assigned to the intervention or control groups using a random number generator. The participants in the intervention group will be placed in different positions than their surgical position during the night before surgery, and the first 36 h after surgery. The control group will receive only routine care. The groups will be evaluated in terms of pressure injury development for at least 72 h, until discharge.
Conclusions: Surgery-induced pressure injuries have important effects on patients, healthcare professionals, and healthcare organizations. Current guidelines recommend that patients be positioned in a different position preoperatively and postoperatively than the surgical position to redistribute the pressure generated during surgery. There is a need for well-designed, comprehensive studies to investigate the effectiveness of this weak evidence-level recommendation. This trial will provide valuable evidence to inform clinical practice, guide surgical nurses, and allow evaluation of the effects of this intervention.

Published: January 2024

Objetivos: describir un caso de diagnóstico prenatal de síndrome de Freeman-Sheldon mediante hallazgos ecográficos y secuenciación completa del exoma fetal.
Materiales y métodos: mujer de 33 años, con antecedentes de hipotiroidismo en tratamiento, a quien en semana 19 se realizó ecografía de detalle anatómico, en la cual se observaron deformidades en el feto en más de dos áreas corporales (extremidades superiores e inferiores), sugiriendo el diagnóstico de artrogriposis. Posteriormente, se brindó asesoría genética y se realizó amniocentesis en semana 20 de gestación, con análisis de la hibridación in situ por fluorescencia, seguido de secuenciación completa del exoma fetal. Este último examen permitió identificar una variante patogénica heterocigota en el gen MYH3, la cual se asocia con la artrogriposis distal tipo 2A.
Conclusiones: la realización de la secuenciación completa de exoma fetal es un factor clave para identificar la mutación del gen MYH3, y confirma que las deformidades evidenciadas por ultrasonido estaban relacionadas con la artrogriposis distal tipo 2A. Es importante hacer la secuenciación de exoma fetal en fetos que muestren hallazgos de malformaciones articulares en el ultrasonido prenatal.

Predictive learning analytics has been widely explored in educational research to improve student retention and academic success in an introductory programming course in computer science (CS1). General-purpose and interpretable dropout predictions still pose a challenge. Our study aims to reproduce and extend the data analysis of a privacy-first student pass–fail prediction approach proposed by Van Petegem and colleagues (2022) in a different CS1 course. Using student submission and self-report data, we investigated the reproducibility of the original approach, the effect of adding self-reports to the model, and the interpretability of the model features. The results showed that the original approach for student dropout prediction could be successfully reproduced in a different course context and that adding self-report data to the prediction model improved accuracy for the first four weeks. We also identified relevant features associated with dropout in the CS1 course, such as timely submission of tasks and iterative problem solving. When analyzing student behaviour, submission data and self-report data were found to complement each other. The results highlight the importance of transparency and generalizability in learning analytics and the need for future research to identify other factors beyond self-reported aptitude measures and student behaviour that can enhance dropout prediction.
Credit Hour Analysis of Adapted Physical Education Courses in Higher Education
Authors: Phelps Ashley , Mason Aaron J. , Lucero Adriana
Published: January 2024

Adapted physical education (APE) is a critical piece to the physical education puzzle. However, this topic is often overlooked from a preparation standpoint in physical education teacher education (PETE). The purpose of this study was to analyze the number of APE credit hours offered in undergraduate PETE programs across the United States. The 2018 Carnegie Classifications were used to help differentiate between types of institutions. Ranging degrees of institutional classification may be a contributing factor to the number and type of credit hours offered. Data analysis indicated that majority of PETE programs in the United States only offer one APE course in the PETE curriculum. Findings from this study are critical to understanding the preparation of preservice physical education teachers (PPETs) in PETE. Findings may also contribute to a conversation on credit hour allocation and whether PPETs are being sufficiently prepared to teach in an inclusive and adapted environment.
Možnosti pridelave hrane na zemljiščih s težkimi kovinami

Published: January 2024

Težke kovine škodljivo vplivajo na prst, ker ovirajo procese humifikacije v prsti. V zemlji prisotne težke kovine se vgradijo v rastline in preidejo v prehranjevalno verigo ter povzročajo huda obolenja. Potrebno je izbrati ustrezen pridelovalni sistem, ki pa je odvisen od geografske lastnosti parcele kot so lastnosti prsti,  matična kamnina oz. sediment, naklon, ekspozicija, smer vetra, odtok površinske vode in sevanja.  V prispevku je prikazan primer rabe poplavljenih zemljišč s toksičnim muljem po poplavah z uporabo vertikalnih sistemov. Gre za pridelovalne pristope, kjer z nalaganjem biomas dvignemo pridelovalno površino in jo ločimo od osnovne zemljine. Ti pristopi omogočajo takojšnjo pridelavo hrane na varen način, saj koreninski sistemi rastlin niso v stiku z matično zemljino.

Published: January 2024

V članku so analizirani vročinski valovi v Sarajevu v obdobju 1901—2018. Predstavili smo trende števila vročinskih valov, njihove dolžine, najvišjih temperatur zraka v vročinskih valovih in kumulative najvišjih temperatur v vročinskih valovih. Obravnavali smo tudi trende univerzalnega termičnega podnebnega indeksa za Sarajevo v obdobju 1961—2018, ki na bolj integralen način prikazujejo obremenilni toplotni učinek na človeka. V Sarajevu opažamo dvig števila vročinskih valov, števila dni v vročinskih valovih in kumulative maksimalnih temperatur v vročinskih valovih. Po letu 1961 narašča tudi obremenilni toplotni učinek v poletnih mesecih, kar nakazuje tudi pozitivni trend vrednosti univerzalnega termičnega podnebnega indeksa.
Možnosti za modro-zeleno infrastrukturo v Mariboru

Published: January 2024

Mesta se soočajo s posledicami podnebnih sprememb, vključno z višjimi poletnimi temperaturami in večjo pogostostjo intenzivnejših padavin, kar povzroča težave s poplavami zaradi neprepustnih površin. Pomanjkanje zelenih površin povzroča ekstremne temperature in manjšanje biodiverzitete, ki je v urbanih območjih skromna. Zato se v zadnjih letih uvajajo pristopi, ki temeljijo na posnemanju naravnih procesov in jih imenujemo modro-zelena infrastruktura. To so urejene površine, ki omogočajo zadrževaje in čiščenje vode, prispevajo k večji biodiverziteti in pozitivno vplivajo na kakovost bivanja. V prispevku so prikazane možnosti uporabe modro-zelene infrastrukture v Mariboru na osnovi predhodno izvedenih projektov.
Stičišče med poukom nemščine kot tujega jezika v OŠ in poukom zunaj učilnice na primeru medpredmetnega povezovanja s ciljem razvijanja okoljske ozaveščenosti
Authors: Fabčič Melanija Larisa , Lipavic Oštir Alja , Cimerman Sitar Maja
Published: January 2024

V prispevku se poskušamo izzivom antropocena, pred katere so danes postavljene šole, približati skozi prizmo treh pristopov: kako z izkustvenim učenjem posredovati učne vsebine v naravnem okolju in tako spodbujati celostni razvoj otrok (pouk izven učilnice), kako se skozi izobraževanje odzvati na kompleksne okoljske izzive (okoljsko ozaveščanje) in kako izboljšati pouk tujega jezika ter zmanjšati obremenjenost otrok s posredovanjem učnih vsebin z različnih področjih pri pouku tujega jezika (CLIL). Pregled teh pristopov kaže, da vsak utemeljeno pridobiva pomen v šolskem kontekstu. Ob tem gremo v prispevku korak dlje in vse tri pristope povežemo, saj se vsebinsko in metodološko nadgrajujejo. Z ekonomičnim združevanjem ciljev in vsebin lahko prispevamo k manjši obremenjenosti otrok, ne da bi ob tem izgubljali dorast znanja. Z metodami učenja, ki izhajajo iz pouka izven učilnice, pa lahko vplivamo na usvajanje kompetenc, ki so potrebne za prihodnost in so običajno manj prisotne pri pouku tujega jezika, kot so sodelovanje, kreativno in kritično pristopanje k izzivom ter empatijo. Dodatne pozitivne učinke opažamo pri zdravju otrok ter kvaliteti učenja in motivacije. Da bi lahko to povezanost pristopov preizkusili v praksi, so potrebne naslednje aktivnosti: izobraževanje učiteljev, ustvarjanje kvalitetnih učnih gradiv, ustvarjanje ustreznih pogojev na šoli in sodelovanje staršev.
Interdisciplinarno povezovanje znanja stroke in tujega jezika na visokošolski ravni
Authors: Podgoršek Saša
Published: January 2024

Poglavje obravnava interdisciplinarno povezovanje znanja stroke in tujega jezika na Filozofski fakulteti Univerze v Ljubljani. Poučevanje tujih jezikov na nefiloloških oddelkih ima dolgo tradicijo, v tem poglavju pa se bom osredotočila na nemščino kot tuji jezik stroke na oddelku za etnologijo in kulturno antropologijo. Rezultati analize dostopnih arhivskih dokumentov kažejo na to, da se je pouk tujih jezikov povezoval s strokovnimi predmeti vsaj od 70. let naprej. Vključeval je predvsem razvijanje branja strokovnih besedil v nemščini, kar predstavlja stalnico še danes. Od takrat se je marsikaj spremenilo, npr. vsebine študijskih programov, skupine so manjše, raven predznanja je nižja, digitalne tehnologije so postale del vsakdana, vsebine v tujem jeziku so enostavno dostopne. Vse to odpira vprašanja o tem, kako temu prilagoditi pouk tujega jezika stroke. Ena od možnosti je opravilno zasnovano učenje (ang. task-based learning), ki temelji na učenju z avtentičnimi opravili, ki so relevantna tako za študijske kot tudi poklicne namene. V empiričnem delu sem raziskala opravilno zasnovano učenje nemščine z namenom ugotoviti stališča študentk in študentov do tega pristopa. Opravilo predstavlja izvedba intervjuja. Rezultati kažejo, da so opravilno zasnovanemu učenju nemščine naklonjeni, so pa opozorili tudi na izzive, s katerimi so se srečali.

У овом раду испитивали смо употребу и преференцију граматичке и семантичке конгруенције код паукалних синтагми на узорку испитаника из Бијељине и непосредне околине. Из овог рада су изостављени испитаници који нису с овог географског простора, као и они чији матерњи језик није српски. Поред ових, остали социодемографски фактори на које смо се ослањали били су: пол, старост, степен образовања и тип средине у којој испитаник живи. За потребе истраживања сачињен је упитник који се састојао из два дијела: први дио с питањима отвореног типа који је захтијевао одговор испитаника и други са скалама процјене. У првом дијелу се нашло 12 реченица које је требало допунити, док се други дио састојао из 24 позитивно оријентисане тврдње: 12 везаних за граматичку конгруенцију и 12 њихових парова везаних за семантичку конгруенцију. Упитник је дистрибуиран онлајн и попунило га је 60 испитаника. Наши резултати указују на то да позитивнији став испитаници имају према граматичкој конгруенцији, те да се за исту опредјељују, док се према семантичкој јавља неутралан или негативан став.

Nematodes and their trophic interactions in the soil microbiome
Authors:   Humboldt-Universität zu Berlin, Germany, Ruess Liliane
Published: January 2024

Sustainable agriculture is highly dependent on a diverse soil microbiome that facilitates ecosystem services such as nutrient cycling and organic matter degradation. These transformations are mediated by microorganisms together with fauna. Nematodes, as important microbial gazers, play a key role in these processes, e.g. nutrient mineralisation. Due to their central position in the soil food web, nematodes provide an essential link for carbon and energy flow from microorganisms to higher trophic levels. These multiple functions of nematodes have made them as useful indicators of soil condition and plant health. However, plant parasites are severe pests that control plant carbon allocation and, in turn, the rhizosphere microbiome. Another aspect is their vector potential for both plant and human pathogenic microorganisms within microbial hotspots. Overall, nematodes have a major impact on agricultural soils, and sustainable management requires consideration of their diverse interactions with the soil microbiome.

Closed Form Solutions to a Class of Pursuit Problems Using Geometric Analogies
Authors: Lovett Michael , Unterkofler Ana
Published: January 2024

This article studies a class of pursuit problems admitting both a simple geometric solution as well as a more general analytic treatment. The results are specialized to demonstrate solutions to certain elementary problems typically posed to high schoolers, although a full analytic treatment, requiring some more comfort with geometry and calculus, is typically avoided at that stage.

Authors: Liu Tongliang , Wen Jianmin
Published: January 2024

To study the coupling mechanism and dynamic response of the end-face movable gear trans-mission system under complex excitation, a specific configuration of end-meshing movable gear reduction mechanism was used to achieve predetermined rigid thrust transmission and mis-matched gear meshing functions, which solved the inherent defects of traditional harmonic gear mechanism thin-wall flexible wheel easy to be damaged by fatigue. Considering the phenomenon of elastic deformation of live teeth accompanied by significant changes in meshing characteristics in the transmission process of end-meshing harmonic reducer, the influence of dynamic meshing parameters, live tooth deformation, time-varying stiffness of tooth meshing, and time-varying backlash on nonlinear dynamic performance was explored, as well as the mechanism of mul-ti-parameter coupling on transmission performance. The nonlinear dynamics model of the end-meshing harmonic reducer is established to solve the chattering prediction problem. Finally, a comprehensive test bed for the transmission system of harmonic reducer with meshing type with adjustable characteristic end was built to verify the correctness of the theoretical model and provide the theoretical and technical basis for exploring the optimal parameter selection of pas-sive vibration suppression problem.

Published: January 2024

Lung cancer remains a formidable global health challenge that necessitates inventive strategies to improve therapeutic outcomes. Conventional treatments, including surgery, chemotherapy, and radiation, have demonstrated limitations in achieving sustained responses. Therefore, the explora-tion of novel approaches encompasses a range of interventions that show promise in enhancing outcomes for patients with lung cancer, particularly those facing advanced or refractory cases. These groundbreaking interventions hold the potential to overcome cancer resistance and offer personalized solutions. Despite the rapid evolution of emerging lung cancer therapies, persistent challenges such as resistance, toxicity, and patient selection underscore the need for continued development. Consequently, the landscape of lung cancer therapy is transforming with the in-troduction of precision medicine, immunotherapy, and innovative therapeutic modalities. Addi-tionally, a multifaceted approach involving combination therapies through the integration of tar-geted agents, immunotherapies, or traditional cytotoxic treatments addresses the heterogeneity of lung cancer while minimizing adverse effects. This review provides a brief overview of the latest emerging therapies that are reshaping the landscape of lung cancer treatment. As these novel treatments progress through clinical trials and integrate into standard care, the potential for more effective, targeted, and personalized lung cancer therapies comes into focus, instilling renewed hope for patients facing challenging diagnoses.

Published: January 2024

Over the past three decades, the region has undergone significant changes that have transformed the social, economic and political landscape. The traces of these changes are particularly visible in the post-socialist states of Central and Eastern Europe. These processes have sometimes fragmented, sometimes reshaped, and sometimes transcended borders, reshaping the region. The focus of this study is on the 'geography' of companies, i.e. the concentration of companies with more than 10 employees in the region in the 15 countries selected, according to various criteria. The countries covered by the study are Albania, Austria, Bosnia and Herzegovina, Bulgaria, Croatia, the Czech Republic, Hungary, Kosovo, Montenegro, Northern Macedonia, Poland, Romania, Serbia, Slovakia, Slovenia, Poland, Slovakia and Slovenia. The data of the active economic operators (over 300 thousand) of the countries included in the study were analyzed by turnover and size. The spatial distribution of enterprises at the NUTS3 level presents a far more diverse picture than what is typically observed in economic indicators such as GDP. Additionally, the disparities in this particular distribution are not as pronounced or distinct as those of general economic indicators.

Published: January 2024

Hydroxyapatite (HAP) is the main mineral component of bones and teeth. It is widely used in medicine as a bone filler and coating for implants to promote new bone growth. Ion substitutions into the HAP structure highly affect its properties. One of the important substituents is manganese. This paper presents the new results obtained by high-precision density functional theory calculations using hybrid functionals, for studies of the Mn/Ca substitutions in HAP in a wide manganese concentration range within 2x2x2 supercell model. The experimental data on the mechanochemical synthesis of HAP-Mn samples with different Mn concentrations are also presented. The comparison between experiment and theory showed good agreement: the HAP-Mg unit cell parameters and volume decrease with increasing degree of Mn/Ca substitution. It is shown that electronic energy levels appear inside the band gap Eg of HAP, which depend on the concentration of Mn and change the photo-excitation energy of HAP, making its effective value Eg* less than the band gap Eg, and generally changing the photoelectronic properties of HAP. It was established that the energies of formation of the substitutions Mn/Ca depend on the position of the Ca atom (Ca1 or Ca2) and on the concentration of manganese. It has been shown that the replacement of calcium cations with manganese occurs predominantly at the Ca2 position.
The 3D-McMap Guidelines: 3-Dimensional Multicomposite Microsphere Adaptive Printing
Authors: Klar Roland Manfred , Cox James C , Raja Naren , Lohfeld Stefan
Published: January 2024

Microspheres, synthesized from diverse natural or synthetic polymers, are readily utilized in biomedical tissue engineering to improve the healing of various tissues. Their ability to encapsulate growth factors, therapeutics, and natural biomolecules, which can aid tissue regeneration, makes microspheres invaluable for future clinical therapies. While microsphere-supplemented scaffolds have been investigated, a pure microsphere-based scaffold with an optimized architecture has been challenging to create via 3D printing methods due to issues that prevent consistent deposition of microsphere-based materials and their ability to maintain the shape of the 3D-printed structure. Utilizing the extrusion printing process, we established a methodology which not only allows to create large microsphere-based scaffolds but also multicomposite matrices into which cells, growth factors, and therapeutics encapsulated in microspheres can be directly deposited during the printing process. Our 3D-McMap method addresses issues with scaffold shape fidelity during and after printing. Carefully timed breaks, minuscule drying steps, and adjustments to extrusion parameters, generated an evenly layered large microsphere-based scaffold that retains its internal architecture. Such scaffolds are superior to other microsphere-containing scaffolds, as they can release biomolecules in a highly controlled spatiotemporal manner. This capability permits to study cell responses to the delivered signals, to develop scaffolds that precisely modulate new tissue formation.
