Analysis of acoustic field distribution of circular equaldistant and non-equidistant two–section electronics microphone array in free space
Authors: Тsekhmistro R.I. , Shapovalov S.V. 
Published: March 2024

The authors described the analysis of the spatial distribution of the acoustic field amplitude of circular microphone lattice. A model – a spherical wave emitter, represented each microphone. An analysis was carried out of the influence of the number of emitters and the radius of the array on the concentration of the acoustic field in the center and at an arbitrary distance. An algorithm has been compiled that makes it possible to take into account an arbitrary even and odd number of emitters located along the length of the arc, both uniformly and unevenly.
The distribution of the complex power of the acoustic field of a linear array of emitters is considered under the assumption that each microphone (emitter) transmits the acoustic field in the form of a spherical wave. According to the classical principles (Lorentz lemma, the “Reciprocity” theorem), we believe that there is no shape of the radiation pattern as formed at short distances (near zone), that is, the distribution of the emitter field in the mode of receiving and transmitting an acoustic signal is identical.
It is shown that at distances between the boundaries of the intermediate and far zones, local areas may appear in which a smaller number of microphones can provide the same acoustic field or even more than with a larger number. This can be achieved by using an internal arc of microphone arrangement, then it is possible to achieve an equivalent field along the axis of the array with a smaller number of microphones located equidistant along the outer radius, it is possible to achieve an equivalent field than with an increased number of them.

Published: March 2024

New series of hydrazones (3a–b) and 1, 3, 4-oxadiazole S-alkylated derivatives (5a–b) of ketorolac (NSAID) were synthesized and their structures were identified by using ATR-FT-IR and ¹HNMR spectroscopic analytical techniques. The synthesized compounds were evaluated in vitro for their antimicrobial activity against Gram-positive bacteria (Staphylococcus aureus), Gram-negative bacteria (Escherichia coli), and fungal species (Candida albicans). After the approval of the ethical committee in the college of pharmacy, University of Baghdad, In vivo screening for their anti-inflammatory activity was done using albino rats as an animal model that were subjected to white egg-induced acute inflammation. Results have shown that the target compounds were successfully synthesized, and it was discovered that they have mild to moderate activity against E.Coil and S.aureus while no effect has shown on C.albicans. In vivo studies showed they were effective in lowering paw edema thickness and had an anti-inflammatory effect similar to that of the standard (ketorolac)

Teaching Primary Geography through Mobile Methods
Authors: Blondin Suzy , Letouzey-Pasquier Justine 
Published: March 2024

Abstract
The teaching of geography has long incorporated mobilities through the practice of fieldwork and field trips as part of teaching. Geographers and child educators have highlighted the importance for children to explore their local area in order to experience “the world” and to engage with their communities. However, mobile methods are usually not integrated in such lessons. Based on primary teachers’ in-service training in Fribourg, Switzerland, and on a collaborative research project on fieldwork-based geography teaching involving primary teachers, the paper aims to discuss the (potential) role of mobile teaching/learning methods in primary school. Our argument also draws from geography curricula in Switzerland and from the scholarly literature on mobile research methods. The article addresses the ways engaging with mobile methods could help pupils/students and teachers to follow mobile processes, to discuss mobilities, to experience places, and to incorporate sensory and corporeal approaches for a more engaging and enlivened learning experience.
Mobilizing Landscape Pedagogies
Authors: Cisani Margherita 
Published: March 2024

Abstract
This article offers a perspective on how mobilities and landscape intertwine outside the academic debate, in the context of learning practices concerned with landscape, sustainability, and citizenship education. The article is based on the analysis of two personal research-action experiences conducted in Italy from 2017 onward in two different contexts: school education and informal education. The first experience concerns a project on promoting sustainable mobility that involved secondary school students, while the second addresses the informal learning activities of urban walking groups. These different experiences are connected and analyzed by adopting the notions of enskillment and friction as interpretive tools to help trace some of the multiple and unpredictable ways in which movement interacts with landscape in pedagogical contexts.

У статті висвітлено екологічну небезпеку підтоплення земель сільськогосподарського призначення внаслідок руйнування дамби Каховської ГЕС. Наведено результати експериментальних досліджень вмісту рухомих сполук важких металів у десяти пробах ґрунту, пробі мулу та намулу відібраних на території Херсонського та Бериславського районів Херсонської області.
За результатами проведених досліджень встановлено перевищення ГДК рухомих сполук свинцю у 4 пробах ґрунту (від 1,04 до 2,9 раза), пробах намулу (у 1,04 рази) та мулу (у 4,2 рази), кадмію – в одній пробі ґрунту (у 1,07 рази) та мулу (у 1,01 рази), нікелю та цинку – у пробі мулу (у 1,03 та 1,01 рази відповідно). За вмістом міді, марганцю та кобальту та перевищень гранично допустимих концентрацій у зразках ґрунту, намулу та мулу не виявлено.
Найвищий ступінь забруднення рухомими сполуками свинцю та кадмію виявлено в пробах ґрунту 2 та 11 відібраних на території с. Тягинка Бериславського району та с. Чорнобаївка Херсонського району.
Зразок ґрунту і намулу, які було відібрано з однієї ділянки, мали ідентичний вміст свинцю та приблизно однаковий вмістом рухомих сполук кадмію, міді та марганцю. Зразок намулу у порівнянні з ґрунтом, характеризувався більшим вмістом рухомих сполук цинку, заліза та нікелю. У зразку мулу (відібраний на території с. Тягинка Тягинська ТГ Бериславський р-н, Херсонська обл.) відмічено перевищення гранично допустимої концентрації за вмістом свинцю (у 4,2 рази) та незначні перевищення за вмістом рухомих сполук кадмію, цинку та нікелю. Намул та мул містять вищий вміст забруднювачів ніж у ґрунтові зразки. Можемо припустити, що вони переміщуючись з потоком води внаслідок руйнування Каховської ГЕС, можуть призвести до забруднення ґрунтів на підтоплених територіях.
За результатами кореляційного аналізу встановлено надзвичайно сильну залежність між умістом всіх рухомих сполук досліджуваних важких металів за винятком сполук марганцю.

Conclusion: This researcher illustrates that the anxiety level of patients with chronic kidney failure undergoing hemodialysis is influenced by characteristics such as age, type of health, and education.
Commentary on mini dental implant insertions in children with ectodermal dysplasia
Authors: Göker Funda , Elbek Çubukçu Çiğdem 
Published: March 2024

Dental implant insertions in children raises significant concerns related to both ethical and medical aspects. On the other hand, some children suffer from several problems such as hypodontia/anodontia and malformations of teeth due to severe conditions like ectodermal dysplasia. In such cases, mini dental implants can be a promising option in enhancing the overall quality of life with positive impact on oral function. However, there are several concerns such as growth disturbances of the jaws since oral
implants are considered to behave similarly to ankylosed teeth and become submerged due to the growth process associated with continued eruption of adjacent natural teeth. Currently, there is a lack of clinical research and systematic review articles in literature that evaluates and compares the outcomes, risks, and advantages of mini dental implant insertions in children with syndromes such as ectodermal dysplasia.
Tooth Saving Solutions- Best Transport Media for Avulsed Tooth? A Review
Authors: Prasada L Krishna , C Priya , K Ramya M 
Published: March 2024

Avulsion is considered one of the most serious types of trauma to teeth as it can displace the tooth from its bone socket and also causes injury to its surrounding structures. The neurovascular supply is greatly hampered by the complexity of this damage, which typically leads to pulp vitality loss. The treatment for avulsed tooth is immediate replantation but, in several situations, it is not possible. The maintenance of viability of PDL cells on the root surface of avulsed tooth is absolutely necessary till the tooth is placed back in the socket to prevent ankylosis and replacement resorption.
Research has led to the development of various transport media for avulsed teeth that can produce conditions that closely resembles the environment of alveolar socket with adequate osmolality, pH, nutrition & metabolites.
This review sheds light on various transport media used for avulsed teeth, its ideal requirements and newer research on such solutions.
