Background: Newborn patients with cyanotic congenital heart diseases with ductus-dependent pulmonary blood flow require neonatal repair, or palliation with a secure source of pulmonary blood flow, up to definitive surgical correction or palliation of the malformation. There is growing experience of percutaneous patent ductus arteriosus stenting to maintain the ductal flow. Patients in need of PDA stenting are newborns or small infants and recent data suggests that a weight of <4 kg increases the risk of thrombosis from femoral arterial catheterisation. Carotid access for newborn cardiac catheterisation avoids femoral arterial injury and improves the catheter course for certain transvasal procedures.The aim of this study was to report the Riga Children’s Clinical University Hospital`s (CCUH) 7 year experience of patent ductus arteriosus stenting using the percutaneous transcarotidal approach in newborn babies and small infants with ductus-dependent critical heart diseases.Methods: A retrospective review of all newborn and small infants who underwent transcatheter arterial duct stenting through the percutaneous carotid artery approach at the CCUH in Riga, Latvia between the years 2013 and 2020.Results: In total, 8 patients underwent PDA stenting using the transcarotid approach between the years 2013 and 2020 in CCUH. The approach in all cases was chosen based on the anatomical features seen on echocardiography. In two cases, early restenting was necessary, while other patients had no procedure-associated complications. In the long term follow-up of 4 patients in two cases, dopplerography of the accessed common carotid artery showed stenotic changes up to 50%.Conclusions: PDA stenting using the transcarotid approach is currently considered a relatively safe method and does not have a greater risk of developing postprocedural complications compared to the transfemoral approach. Transcarotidal PDA stenting in neonates and small infants with ductus-dependent critical congenital heart disease is possible in small volume paediatric cardiac surgery centre to stabilise the patient prior to definitive surgery or palliation of complex CHD. The vascular access should be chosen depending on the anatomical features of the patient and the competency of the cardiac interventionalist. From our experience, long-term changes in the affected common carotid artery may develop in a substantial number of cases, they may not be clinically significant in midterm follow-up period but have to be reevaluated. However, further randomised studies are necessary with large cohorts and longer follow-up period.

Published: February 2025

Ulmus pumila L. is widely spread in arid and semi-arid regions of China as a soil-conservation, sand-fixing, and resistant plant. Due to its rapid growth, winter hardiness, low demand for soil fertility and moisture, tolerance of drought, resistance to gaseous pollution and soil salinization, and ability to spread under favorable conditions, U. pumila has been widely cultivated in forests, urban plantations, and along transportation right-of-ways. In some regions, U. pumila is resistant to Dutch elm disease (DED), and verticillium wilt but it is susceptible to bacterial wetwood disease. The trees’ health is usually assessed according to crown and trunk appearance. We assumed that some symptoms may be associated with specific types of pathologies or indicate the latent development of the disease, which is difficult to diagnose visually. The study aimed to search the relations between the distribution of visually detectable symptoms of U. pumila weakening and tree groups with apparent signs of bacterial wetwood and Dutch elm disease. In June – September 2023, the health condition of Ulmus sp. was examined in forest shelterbelts along the M 03 highway, passing through the territory of Kyiv, Poltava, and Kharkiv regions. In this study, the data on 624 U. pumila trees in 11 sample plots were used, particularly, the diameter at breast height (DBH), the class of the health condition, defoliation, the prevalence of dry branches, epicormic shoots, bark beetle infestation, local bark death, and collar rots. Based on these indicators, four groups were examined – with symptoms of bacterial wetwood, DED, weakening of unknown etiology (symptomatic trees), and without visual symptoms of weakening (asymptomatic trees). DBH of symptomatic trees was significantly less than that in asymptomatic and DED-infected trees. The average HCI was from 2.5 for asymptomatic to 3.3 for wetwood disease-infected trees, and 3.5 for DED-infected trees. DED-infected trees were found to have the highest level of defoliation and the lowest prevalence of epicormic shoots. Among wetwood-infected trees, the bark beetle infestation significantly increased with an increase in HCI and defoliation and decreased as the diameter of the trunks decreased. Principal components analysis confirmed the highest association of bark beetle infestation with DED, epicormic shoots with wetwood disease, and dry branches with other symptomatic trees. Symptomatic trees occupied an intermediate position by HCI. Although they have no direct signs of fungal or bacterial disease, health worsening may indicate a latent infection.
EFFECT OF ANNEALING TEMPERATURE ON THE STRUCTURAL AND THERMOELECTRIC PROPERTIES OF CuFeS2 NANOPARTICLES PREPARED BY THE HYDROTHERMAL METHOD
Authors: Ali Safaa H. , Mohammed Saad S. 
Published: February 2025

The current study described precise and simple hydrothermal method used to synthesize CuFeS2 nanoparticles. The thermoelectric properties of CuFeS2 nanoparticles were studied under different conditions of annealing treatment. The phase structure, functional groups, and thermal stability of the CuFeS2 nanoparticles samples were analyzed via X-ray diffractometer (XRD), Fourier transform infrared spectroscopy (FT-IR), and thermogravimetric analysis (TGA). The X-ray diffraction (XRD) results of the synthesized nanoparticles closely matched the CuFeS2 chalcopyrite patterns. FT-IR measurements confirmed the presence of the characteristic S-O, Fe-S, and O-H groups in the structure of the prepared nanoparticles. The TGA results indicate that the CuFeS2 nanoparticles are thermally stable below 650°C. The scan electron microscope (SEM) measurements revealed that the particle size of all the samples was less than 100 nm after the annealing treatment. The optical measurements showed that the absorbance edges of the CuFeS2 samples shifted to longer wavelengths after the annealing treatment. The thermoelectric measurements indicated that the annealing treatment modulated the electrical conductivity, Seebeck coefficient, power factor, and thermal conductivity of the CuFeS2 samples.

AbstractA successful spray-drying encapsulation is supported by the use of suitable matrix material. This research aimed to study the properties of maltodextrin-alginate matrix solution and its encapsulated iron powder. The study was conducted using the variation of iron concentration (8–20 mg g−1 matrix) and ratio of maltodextrin-alginate (10:0; 10:0.5; 10:1; 10:1.5; 10:2; 0:2). The results showed that a higher iron concentration increased the viscosity of the matrix solution, which led to the formation of higher moisture content particles, but reduced the encapsulation efficiency. Meanwhile, an increased ratio of maltodextrin-alginate allowed an increase in the viscosity of the matrix solution, the encapsulation efficiency, and the moisture content of the particles. However, iron loading capacity improved by increasing iron and alginate concentration. All samples appeared to be amorphous materials with a faster iron release at a pH 6.8 than that at a pH 1.2. In addition, incorporation of alginate improved the particle size, thermal stability, and antioxidant activity of the encapsulated iron powder. In brief, the improvement of the encapsulation efficiency, iron release, and thermal stability of spray-dried iron powder are highlighted in this study, which are important in food fortification and processing.
Technique to Protect the Palatal Donor Area After Taking a Free Gingival Graft: Patchwork Technique

Published: February 2025

ABSTRACT
The objective is to describe a technique to protect the donor area after taking a free gingival graft. A partial de-epithelialization of the palatal area is performed with a lentil bur mounted in a dental turbine. A partial thickness flap is then created to harvest the superficial connective tissue layer. Subsequently, two collagen sponges are placed into the wound. The sponges are compressed and secured by two sling stitches. Once hemostasis is obtained, a uniform layer of flow composite is placed and light-cured. Finally, a sling stitch is added to secure and compress the composite layer. Postoperatively, the donor area showed satisfactory healing after 14 days, with partial healing after the first revision and complete epithelialization during the second revision, with no reported pain or discomfort. Thus, the patchwork technique may be a more straightforward, predictable, and cost-effective alternative that protects the donor area, improves healing, and reduces pain.
Utilization of chronic intrasocket granulation tissue for immediate implantation in the type III extraction socket of a maxillary anterior tooth
Authors: Kim Sungtae , Han Hee-seung , Cho Young-Dan 
Published: February 2025

Abstract
Traditionally, intrasocket granulation tissue (IGT) has been regarded as infected tissue to be removed during extraction to facilitate bone healing. However, recent findings suggest that IGT can support primary closure, preserving keratinized mucosa and enhancing healing potential without requiring additional soft tissue grafting. This case series explores the application of IGT as an extended flap in immediate implant placement within type III extraction sockets, specifically in the anterior maxilla of healthy patients. A dense, thick IGT was utilized to extend the gingival flap, achieving tension-free primary closure and maintaining mucogingival junction stability. This technique allowed for socket preservation with sufficient vestibular depth and reduced surgical intervention. Consequently, this approach may offer a viable alternative for immediate implantation in type III extraction sockets, particularly in aesthetic areas where keratinized mucosa and soft tissue stability are essential.
Personalising Learning: Do Teachers Use Student Voice and Choice at Secondary School?
Authors: Щевлянин Михаил , Королева Диана 
Published: February 2025

The article is dedicated to the modern concept “student voice and choice,” which is an essential component of personalised learning. The research was conducted in the Russian schools that integrated the educational platform with personalised learning methodology, “SberClass.” On the basis of 24 interviews with the teachers the article:
1) indicates teachers’ attitude towards the concept “student voice and choice”;
2) investigates the application of the concept in the teacher practice;
3) analyses what benefits and barriers the teachers perceive in giving students the possibility to express their opinions and choose in the learning.
One of the findings is the contradiction between teachers’ positive attitude towards the concept and unreadiness for the realisation in teacher practice at the secondary school.
The Foundations for the Current Development of National Mathematical Education, Laid by its Leaders in the 20th Century
Authors: Семенов Алексей , Абылкасымова Алма , Рудченко Татьяна 
Published: February 2025

The work analyzes the views on the development of mathematical education by G.V. Dorofeev and other leading Russian researchers of school mathematical education of the 20th century, including V.V. Firsov and A.Ya. Khinchin. Important for them were the idea of “humanitarianization of mathematical education” and the related concept of “education in mathematics”, in modern terminology – about meta-subject and personal results achieved in a mathematics course. The central areas of humanitarization of mathematical education are logic and language, rational thinking, and effective communication. Within the framework of these ideas, the importance of including in a mathematics course problems that “don’t know how to solve” (for a student who is offered such a problem), unexpected, shallenging, creative ones is considered. In the context of the ongoing digital transformation of education, the role of such tasks is increasing, and the role of routine, standard tasks is decreasing – they can be quickly and accurately solved using a computer. Respectively student and teacher resources can be reallocated. Another important concept discussed in this article is differentiation. There are different interpretations of this concept, common to which is the leading role of the student. The most important thing is “level differentiation”. This concept was introduced by V.V. Firsov in the 1980s. The central element of this concept is that each student achieves all intended goals. It obviously follows from this requirement that goals must be personal for each student. The simplest and most useful option seems to be one in which the goal is adapted to the student’s initial level, abilities and motives. In the context of the digital transformation of schools, the ideas of G.V. Dorofeev and his associates can be fully implemented in the education systems of the Russian Federation and the Republic of Kazakhstan.
A Comparison of Machine Learning Methods of Association Tested on Dense Nodal Arrays

Published: February 2025

Abstract
The association of phase picks to form events is one of the fundamental components of seismology. Large and dense sensor networks, such as &gt;1000 geophone arrays (and distributed acoustic sensing), offer unique challenges in association due to the vast numbers of observations and high likelihood of errant picks. In addition, the large number of stations can greatly increase the time it takes to perform the association. For this reason, machine learning (ML) methods might provide a more optimal method of association for such networks. In this work, we examine how well ML methods (e.g., Gaussian mixture model association, PhaseLink, and Graph Earthquake Neural Interpretation Engine) can incorporate dense seismic arrays into regional networks and how well they handle the increasing numbers of stations. We test their capabilities on two dense seismic deployments, one within Rock Valley Nevada (52 nodes and a 9-station sparse local network), and the LArge-n Seismic Survey in Oklahoma dense nodal array (&gt;1800 vertical-component geophones). Processing data from these two different styles of dense seismic deployments allows testing of how the ML algorithms can merge array data with a broader regional network, how they deal with poorly picked phases, and how they handle anthropogenic noise. We compare the ML-associated bulletins to those obtained using the Rapid Earthquake Association and Location algorithm, a more traditional method of association. We find that there are very small differences in results between the methods for small networks (&lt;100 stations) with low pick rates. For large networks (&gt;1000), there are enough errant picks that some of the ML methods start to create false events out of noise. We also find that the ML methods vary in computation time significantly but are all faster than the traditional method tested here.

The health mentoring activity on fulfilling basic human needs (sleep and activity) for Quran Tahfidz students at PPTQ Muhammadiyah Bani Husein - Kalipepe, Yosowilangun, was conducted to increase participants' knowledge and awareness about the importance of adequate sleep, physical activity, and the use of herbal remedies as natural solutions. This activity consisted of an initial assessment (pre-test), material presentation, and a final assessment (post-test). The pre-test results showed that most participants had limited knowledge about basic human needs. After presenting the material using interactive lectures and media such as PowerPoint and X Banners, the post-test results indicated a significant increase in participants' understanding. The material covered the importance of adequate sleep, physical activity, and herbs that can be used to address sleep disorders, such as pandan, lavender, jasmine, ginseng, nutmeg, and green tea. This knowledge improvement aligns with Maslow's theory on fulfilling basic physiological needs. The results of this activity demonstrate that health education conducted with appropriate methods and supported by effective media can positively impact the increase of knowledge and community health. The authors thank the parties who supported this activity and declare no conflict of interest in the implementation of this community service activity.
