Investigate the Effect of Coating Concentration and Coating Thickness on the Anti-microbial Properties of Polycarbonate Sheet
Authors: Saleh Alkarri 
Published: June 2024

This paper investigates the effect of coating concentration (ppm), and coating thickness (µm) on the anti-microbial properties of polycarbonate sheets using a variety of anti-microbial agents (Cu-infused Mg(OH)2, Mg(OH)2, Cu(OH)2, MgO, CuCl2.2H2O, and ZnO). In addition, a complete analysis was performed for all agents to rank the best agent in terms of the highest anti-microbial performance against E. coli K-12 MG1655 in two time intervals (4 and 24 hours). The coating concentration (ppm) was found to be a significant factor in the anti-microbial characteristics for Cu-infused Mg(OH)2, Mg(OH)2, Cu(OH)2, MgO, CuCl2.2H2O, and ZnO (p = 0.004, p < 0.0001, p < 0.0001, p = 0.0297, p = 0.0011, and p = 0.0130 respectively). The coating thickness (µm), on the other hand, was found to be a major contributor to the anti-microbial properties of Cu-infused Mg(OH)2, Mg(OH)2, Cu(OH)2, MgO, and CuCl2.2H2O (p < 0.0001, p = 0.0004, p = 0.0011, p = 0.0310, and p < 0.0001 respectively). The analysis determined that the coating did not influence the anti-microbial properties of ZnO. The interaction between the coating concentration (ppm), and the coating thickness (µm) was found to be a significant factor for Cu-infused Mg(OH)2, Cu(OH)2, MgO, CuCl2.2H2O, and ZnO (p < 0.0001, p = 0.0001, p = 0.0004, p < 0.0001, and p < 0.0001 respectively), however, this was not a significant factor for Mg(OH)2. Highlights •	The anti-microbial activity of the inorganic material is dependent on the particle shape and size. •	Particles with sharp edges will provide additional physical injuries to the microorganisms. •	Smaller particle size will provide higher surface area therefore better interaction with microorganisms. •	The coating concentration and coating thickness will be crucial to the anti-microbial activity. •	The thermal embossing techniques demonstrate good adhesion to the surface.
Melatonin and gut microbiome

Published: June 2024

In recent years, studies of the human microbiome have led to the development of the gut-brain axis theory, which proposes a relationship between the gut bacterial community and its metabolites and chemical compounds, as well as physiological and pathological processes in the brain. Melatonin is considered one of the potential links in this relationship.The review provides brief information about the synthesis, metabolism and effects of melatonin in the body. General patterns of the effect of melatonin on the intestinal microbiota under various conditions, such as oral and intraperitoneal melatonin administration, sleep deprivation, as well as the results of studying the microbial community with measurement of hormone levels are considered.Results are presented for families and individual genera of microorganisms and are obtained from studies in animal models or in the research of diseases. The article also notes some additional parameters which are supposed to be relevant to the interaction of melatonin with gut microbiome. Special attention is paid to butyrate as one of the most studied possible parts in this interaction. Studying the relationship between melatonin and microbiome is of interest for basic science and practical medicine.Literature search was carried out using electronic information resources PubMed and eLibrary.

Background. In phthisiology, all recurrent respiratory tract infections are considered risk factors for tuberculosis (TB) in children. A differentiated assessment of the predictive value of recurrent upper and lower respiratory tract infections will improve the effectiveness of selective TB screening.The aim. To carry out a differentiated assessment of the predictive value of recurrent upper and lower respiratory tract infections in children with tuberculosis and HIV coinfection.Materials and methods. We conducted a retrospective study (2010–2020) of the anamnestic prevalence of recurrent respiratory tract infections in 249 children divided into 4 groups: 72 healthy children (HC); TB – 65 children with tuberculosis; TB/HIV – 56 children with HIV-associated TB; HIV – 65 children with HIV infection.Results. Recurrent lower respiratory tract infections were detected in the anamnesis of 15 (23 %) children of the TB group and in 3 (4 %) children of the HC group (p < 0.001; odds ratio (OR) – 8.6). Lower respiratory tract infections were most common during the year preceding TB disease (11 out of 15 cases), within 2 years before the inclusion of children in the study – in 4 out of 15 cases (p = 0.027; OR = 11.0). In the TB/HIV group, the prevalence of lower respiratory tract infections compared to the HIV group was established only during the year preceding TB – 24 out of 33 cases (73 %) versus 10 out of 34 cases (29 %) in the HIV group (χ2 = 10.9; p = 0.001; OR = 6.4). The occurrence of upper respiratory tract infections in pairs of HC group – TB group and HIV group – TB/HIV group had no statistical differences.Conclusion. The predictor of TB in children regardless of their HIV status is the recurrent lower respiratory tract infections, registered during the year preceding the TB disease. The recurrent infections of the upper respiratory tract do not affect the realization of TB in children, regardless of their HIV status.

Published: June 2024

Background. In demographic processes, a significant place is occupied by such a type of immigration as the return of representatives of the indigenous population to the mother state. Many states, including Kazakhstan, adopt special programs aimed at adapting immigrants to the host society. However, the integration of kandas (fellow countrymen) into Kazakh society is not always painless for both the repatriates themselves and the local population.The aim of the study. To justify the need for a pragmatic approach to immigration in modern Kazakhstan, taking into account new risks and challenges.Materials and methods. The methodology for studying social phenomena and interactions in concept is based on classical approaches: the theory of structural functionalism, symbolic interactionism, conflict theory, the theory of communicative action. To collect primary social information, qualitative and quantitative methods of sociology were used: statistical information analysis, focus groups, interviews, questionnaires.Results. The resettlement of ethnic Kazakhs from farand near-abroad countries and their settlement in Kazakhstan affect the change in the demographic structure of the regional population. On the one hand, mostly young people of active, working age arrive, who can contribute to the economic development of the country. On the other hand, not all immigrants have the working qualifications necessary for a particular region. The conditions of turbulent social processes and complicated geopolitical situation require a pragmatic approach to immigration, which takes into account education, profession and other characteristics of immigrants.Conclusion. Resettlement processes in manpower-surplus areas require special attention from the authorities. It is necessary to look at resettlement processes as a tool for solving socio-economic problems. First of all, these objectives include improving the well-being of the local population living in these regions and reducing risks and challenges for the state.

Conscientious Objection or Objecting to the Conscience?
Authors: Houston Christopher 
Published: June 2024

Abstract
In certain domains of contemporary life, political action connected to people's conscience is of central significance. But what is the conscience, and how may it be studied? Much of the anthropological study of conscientious objection has occurred in places where freedom of conscience is codified as a legal possibility. By contrast, this article investigates the social life of the conscience in Turkey, where discourse on freedom of conscience has been crucial to its system of laicism but which does not recognize the right of conscientious objection to conscription. Drawing upon the testimonies of refusers, it examines the qualities of conscience they reveal, showing their shared characteristics with the ethical subjectivity of objectors in ostensibly more liberal contexts. I adapt the term “forensic conscience” to describe these common characteristics, stressing their universal dimensions.
A Thought Experiment in the Wild
Authors: Heywood Paolo 
Published: June 2024

Abstract
This article aims to complicate the opposition between “thick description” and “thin” thought experiments by constructing a thought experiment of its own. It compares the use of examples—thick and thin—in the work of Malinowski and Wittgenstein, who came to extremely similar conclusions about the importance of context to meaning, the former around a decade before the latter. By imagining the—by no means implausible—possibility that Wittgenstein read Malinowski, the article asks how it might change anthropological views about thickness and thinness if it turned out that one of the major philosophical sources of our disciplinary preference for “thick description” as a generalized prescription for ethnography took some inspiration for such ideas from Malinowksi's more modest and restricted empiricism.

Стаття присвячена проблемам формування наукового підґрунтя системи конфіденційного забезпечення завдань кримінального провадження в умовах сьогодення. Визначено, що у межах наукових досліджень не визначені всі теоретичні, правові, морально-етичні та організаційно-процедурні проблеми наукового забезпечення реалізації означеної інституції. Метою статті на ґрунті системного підходу до використання слідчим конфіденційної співпраці з іншими особами під час кримінального провадження, визначити напрямки формування теоретичного підґрунтя формування організаційно – тактичної моделі використання конфідентів під час кримінального провадження. Визначено, що досвід використання конфідентів у провідних країнах світу свідчить, що вони виконують, як правило, три головні функції: повідомляють про поведінку підозрюваних, сприяють встановленню їх особистих даних, виявленню злочинних намірів, дають інформацію про місце перебування викраденого майна; вводять в оману злочинців (аналог забезпечення рішення тактичних задач слідства під час негласних слідчих (розшукових) дій в Україні); свідчать у суді на користь звинувачення (псевдонімний допит) і т. ін. Доведено, що підґрунтям розробки нових нормативних актів можуть стати наступні теоретико-прикладні дослідження: формування стратегії використання слідчим світового досвіду конфіденційного співробітництва з іншими особами та напрями його впровадження в Україні; розробка оптимальних моделей використання слідчим конфіденційного співробітництва з іншими особами під час кримінального провадження по фактах вчинення злочинів різних видів; розробка організаційних форм реалізації конфіденційного співробітництва слідчого з іншими особами під час кримінального провадження та їх закріплення у чинному законодавстві; створення тактичних алгоритмів конфіденційного співробітництва слідчого з іншими особами під час кримінального провадження на основі досягнень психології та соціології; розробка організаційно-тактичних основ використання слідчим конфіденційної співпраці з іншими особами залежно від їх категорії та злочинів, за фактами яких здійснюється розслідування. Визначено, що всі дослідження повинні бути спрямовані на формування проактивної парадигми використання конфіденційного співробітництва з іншими особами під час кримінального провадження на ґрунті реалізації загальносвітових принципів забезпечення прав і свобод людини та досягнень інших галузей науки.

Distribusi listrik tegangan menengah di Indonesia didominasi oleh saluran tegangan menengah (SUTM). SUTM adalah konstruksi distribusi tenaga listrik non-isolasi dengan tegangan berkisar antara 5kV hingga 20kV menghubungkan gardu induk dengan pelanggan. SUTM sering mengalami gangguan sesaat hingga permanen akibat faktor binatang seperti kukang dan tupai. Penelitian ini berfungsi untuk merancang suatu sistem deteksi binatang berbasis IoT untuk mencegah dan memperingatkan dalam bentuk gambar jika terdapat binatang atau suhu berlebih di jaringan SUTM. Sistem deteksi ini menggunakan sensor PIR HC-SR501 untuk mengidentifikasi gerakan binatang, sensor DHT22 untuk deteksi suhu, buzzer ultrasonik untuk mencegah binatang, dan ESP32-CAM untuk mengambil gambar. Data yang diperoleh terkirim di Thingsboard menggunakan mikrokontroler ESP32, serta gambar terkirim pada aplikasi Telegram. Uji coba dilakukan secara subsistem dan keseluruhan dengan simulasi dan pengujian langsung di lapangan pada gardu hubung SUTM. Hasil pengujian menunjukkan bahwa sistem dapat mendeteksi pergerakan binatang dengan sudut deteksi hingga ∠63,4° dan sensor DHT22 dapat memantau suhu dengan nilai akurasi suhu 98,78%. Buzzer ultrasonik dapat mengusir binatang dengan frekuensi 35kHz. Delay pengambilan gambar ESP32-CAM ketika variabel terpenuhi bervariasi tergantung pada provider yang digunakan, dengan Telkomsel memiliki rata-rata delay terkecil sebesar 1,39 detik, provider Axis rata-rata delay sebesar 1,89 detik dan provider Tri memiliki rata-rata delay sebesar 2,34 detik
