Community detection on elite mathematicians’ collaboration network
Authors: Huang Yurui , Wang Zimo , Tian Chaolin , Ma Yifang
Published: August 2024

Purpose

This study focuses on understanding the collaboration relationships among mathematicians, particularly those esteemed as elites, to reveal the structures of their communities and evaluate their impact on the field of mathematics.

Design/methodology/approach

Two community detection algorithms, namely Greedy Modularity Maximization and Infomap, are utilized to examine collaboration patterns among mathematicians. We conduct a comparative analysis of mathematicians’ centrality, emphasizing the influence of award-winning individuals in connecting network roles such as Betweenness, Closeness, and Harmonic centrality. Additionally, we investigate the distribution of elite mathematicians across communities and their relationships within different mathematical sub-fields.

Findings

The study identifies the substantial influence exerted by award-winning mathematicians in connecting network roles. The elite distribution across the network is uneven, with a concentration within specific communities rather than being evenly dispersed. Secondly, the research identifies a positive correlation between distinct mathematical sub-fields and the communities, indicating collaborative tendencies among scientists engaged in related domains. Lastly, the study suggests that reduced research diversity within a community might lead to a higher concentration of elite scientists within that specific community.

Research limitations

The study’s limitations include its narrow focus on mathematicians, which may limit the applicability of the findings to broader scientific fields. Issues with manually collected data affect the reliability of conclusions about collaborative networks.

Practical implications

This study offers valuable insights into how elite mathematicians collaborate and how knowledge is disseminated within mathematical circles. Understanding these collaborative behaviors could aid in fostering better collaboration strategies among mathematicians and institutions, potentially enhancing scientific progress in mathematics.

Originality/value

The study adds value to understanding collaborative dynamics within the realm of mathematics, offering a unique angle for further exploration and research.
The role of genetic and epigenetic factors on the development of cognitive deficits in patients with severe trauma after repeated anesthesia (literature review)
Authors: Kuchina S. N. , Spivak I. M. , Shchegolev A. V. , Levshankov A. I.
Published: August 2024

Introduction. When a severe combined injury occurs in a patient, various biochemical, humoral, cellular and pathophysiological mechanisms of protection against death occur. Immediately after receiving an injury, the patient is hospitalized in a hospital for medical care, where every effort is made to stabilize the condition, resorting to the appointment of various instrumental and laboratory tests. The development and course of traumatic illness, and treatment outcomes in patients with similar injuries are sometimes dramatically different. Based on this, it was suggested that there is a genetic basis for the regularity of the disease, as well as that exogenous factors themselves can affect certain molecular genetic markers, primarily telomere length.

The objective was to summarize the current literature data on the study of changes in telomere length, as well as the influence of exogenous and endogenous factors on their shortening. To determine the prospects of studying the effect of polymorphic alleles of various genes on the development of a pathological condition in a certain cohort, namely the development of cognitive dysfunction in patients with severe trauma after repeated anesthesia.

Materials and methods. The literature search and analysis was performed in the medical information systems PubMed and eLibrary, using the keywords «telomere», «trauma», «cognitive», and «anesthesia».

Results. Since 1950, data on the study of human telomeres began to be published abroad. Between 2002 and the present, 39 articles were published on PubMed when searching for the keywords «anesthesia» and «telomeres»; by keywords «cognitive», «trauma», «telomeres» – 27. Most articles are devoted to the effect of childhood trauma on changes in telomere length, as well as the assessment of short telomeres in patients with various cognitive deficits. However, there are no articles devoted to studying the effect of repeated anesthesia, as an exogenous factor, on the genetic apparatus of a patient with severe combined trauma.

Conclusion. The literature highlights the influence of various exogenous factors on the shortening of telomere length, especially in the context of childhood trauma, cognitive impairment in various observed groups. The section related to the effects of anesthesia and their number, the consequences for the genetic apparatus of a particular person, is open for study.

Authors: Paromov K. V. , Svirskii D. A. , Hussain A. , Neledova L. A. , Kirov M. Yu.
Published: August 2024

Introduction. New anesthesia techniques require evidence of the safety of their implementation, however there is still the opinion about negative impact of regional anesthesia on heart performance and central hemodynamics. The objective of our study was to evaluate effect of regional anesthesia on systolic and diastolic myocardial function in off-pump coronary artery bypass grafting (OPCAB).

Materials and methods. A prospective randomized controlled trial included 45 patients who underwent elective OPCAB, equally divided into 3 groups – general anesthesia in combination with epidural anesthesia (GA+EA), general anesthesia with erector spinae plane block (GA+ESPB) and general anesthesia without regional anesthesia (GA). The systolic function of the left (LV) and right ventricle (RV), as well as the diastolic function of the LV were evaluated during five stages perioperatively, using echocardiography and thermodilution via Swan-Ganz catheter.

Results. There were no intergroup differences in parameters of LV or RV systolic function and LV diastolic function during study stages. Perioperatively, there was a decrease in LV end-diastolic volume in the groups of OA+ESPB (p = 0.001) and OA (p = 0.003).At the end of the first postoperative day (POD), pulmonary artery wedge pressure decreased in the groups of OA+EA (p = 0.003) and OA+ESPB (p = 0.008); meanwhile, ejection time (p = 0.003) and velocity-time integral (p = 0.005) from RV reduced only in the OA+ESPB group. In the OA+EA group at the end of POD1, the reservoir strain of left atrium (p = 0.022) and isovolumic relaxation time (p = 0.006) decreased.

Conclusion. In OPCAB, epidural anesthesia and ESPB do not result in deterioration of LV systolic and diastolic function and do not have a negative impact on the RV.

Authors: Pratiwi A. , Rum M. , Palinrungi A. S. , Salahuddin A. , Faisal F. , Nurdin H.
Published: August 2024

Introduction. In the evolving landscape of anesthetic practices for short-duration urologic procedures, the quest for an anesthetic agent that balances efficacy with minimal side effects remains a significant clinical challenge.

The objective was to compare the efficacy and safety of 2% hyperbaric prilocaine and 0.5% hyperbaric bupivacaine in spinal anesthesia.

Materials and methods. A comparative analysis was performed in terms of onset and duration of sensory and motor block, incidence of side effects (hypotension and bradycardia), and overall patient outcomes in urologic endoscopy. The research sample was divided into two groups, each consisting of 20 patients. In one case, spinal anesthesia was performed using 2% hyperbaric prilocaine (40 mg) + fentanyl 25 mcg, in the other – 0.5% hyperbaric bupivacaine (10 mg) + fentanyl 25 mcg.

Results. Prilocaine offers a faster onset of sensory and motor block and a shorter duration of sensory block compared to bupivacaine. Prilocaine also showed a quicker recovery of full motor function and had a significantly lower incidence of side effects such as hypotension and bradycardia.

Conclusion. These results suggest that 2% hyperbaric prilocaine could be an alternative to 0.5% hyperbaric bupivacaine in spinal anesthesia for urologic endoscopy, especially in procedures requiring quick recovery. The promising results of prilocaine in such short-duration surgeries can also prompt a reevaluation of anesthesia protocols across various surgical interventions and lead to enhanced patient outcomes, emphasizing safety, comfort, and efficacy of surgical care.

Introduction. Theoretical and practical issues of the short-term and long-term prediction of the onset of multiple organ dysfunction syndrome (MODS) and its outcomes in newborns is a promising area of neonatology, since it allows a doctor to be warned about an impending catastrophe, and opens a «window of opportunity» for timely correction of treatment tactics and prevention of complications.

The objective was to study the epidemiological features and medical consequences of multiple organ dysfunction syndrome in full-term and premature newborns born in critical condition.

Materials and methods. The stage of retrospective epidemiological analysis was conducted in 2023. The prevalence and outcomes of MODS over a ten-year period (2012–2022) in full-term and premature newborns in the Kemerovo region-Kuzbass were studied.

Results. During the period 2012–2022, the mortality rate of children born in critical condition decreased by 2 times, the proportion of patients with MODS and persistent multiple organ dysfunction syndrome (PMODS) decreased, but this phenomenon did not lead to a decrease in the mortality rate of children with developed MODS. In the present study, MODS and PMODS most often developed in extremely immature newborns.

Conclusion. Nosologies of newborns with MODS and PMODS were represented by intrauterine generalized infection, congenital pneumonia and, to a lesser extent, cerebral ischemia and congenital malformations.

Initially, ISIS was based in Syria and Iraq and carried out a lot of violence there. ISIS recruits foreign fighters from various countries and is termed “jihadists”. On the other hand, the fight against ISIS is carried out by the state, militia, and foreign fighters. These foreign fighters came to Syria from various countries individually to fight ISIS. This research aims to answer research questions regarding the goals of foreign fighters in fighting ISIS. The research was conducted qualitatively by conducting interviews with a number of informants and then analyzed by coding techniques using Atlas.ti software. The findings of this study are that foreign fighters have individual, ethnic, religious, ideological goals, to stop the occupation, and to overthrow the government.
Difusi Norma Kerja Sama Keamanan ASEAN Melawan Perdagangan Manusia
Authors: Pradityo Rahmadanu , Fajrilla Sidiq Mabda Haerunnisa , Kurniawan Yandry
Published: August 2024

The United Nations (UN) ratified the United Nations Convention against Transnational Organized Crime (UNCTOC) in 2000 as the norm for international security cooperation in addressing transnational crimes that threaten the global security. Transnational crimes include human trafficking that involves a wide range of criminal organizations and networks. Therefore, ASEAN also refers to UNCTOC and the Trafficking in Person (TIP) Protocol in overcoming transnational crimes, especially the fight against human trafficking. This paper proposes questions ASEAN's attitude to not adopt all UNCTOC norms and Trafficking in Person Protocol in the ASEAN Convention on Trafficking in Person, Especially Women and Children (ACTIP). This paper uses qualitative research methods and norm diffusion theory as the analytical framework. This study found that ASEAN did not fully adopt external norms because there were parts that were not in accordance with ASEAN's internal norms, so that ASEAN made adjustments between external norms and ASEAN internal norms in the formation of ACTIP which referred to ASEAN's cognitive priors, so that ACTIP became the security cooperation norms with human rights element.

Authors: Laura Essy , Zain Mardiati , Agustin Fauzia
Published: August 2024

This study aimed to assess the impact of lerak fruit and probiotic supplementation on varying levels of ammoniated palm fronds in sheep rations, as well as to determine the optimal inclusion rate of ammoniated palm fronds in the presence of lerak fruit and probiotics. Employing an experimental approach, a Latin Square Design was utilized, with four sheep as rows, four periods as columns, and four rations as treatments. Treatments included: A) 50% field grass + concentrate, B) 20% field grass + 30% ammoniated palm fronds + 50% concentrate + lerak fruit + probiotics, C) 10% field grass + 40% ammoniated palm fronds + 50% concentrate + lerak fruit + probiotics, and D) 0% field grass + 50% ammoniated palm fronds + 50% concentrate + lerak fruit + probiotics. Results indicated significant differences (P<0.05) between dry and organic matter intake treatments and body weight gain. However, no significant differences (P>0.05) were observed in the digestibility of dry and organic matter. These findings suggest that supplementation with up to 40% ammoniated palm fronds in sheep rations, probiotics, and lerak fruit yielded comparable digestibility and livestock performance as the control. This study provides valuable insights into optimizing sheep rations with alternative feed ingredients, contributing to enhanced animal nutrition practices.

Authors: Naswa Ruchika , Makhija Neeti , Rajashekar P. , Kalra Sheetal , Kiran Usha
Published: August 2024

Objectives:

Congenital heart diseases (CHDs) and their operative management are a source of emotional and financial stress to the patient and family. Rajyoga meditation (RYM) is a specific art and science of meditation that encompasses but is not limited to mind-body medicine theories, inculcation of values in life, and development of life skills for complete physical, mental, and spiritual well-being. The role of RYM has never been studied in CHD patients, especially children. This study aimed to evaluate the efficacy of the RYM program on resting metabolic rate (RMR) and post-hospitalization behavior questionnaire (PHBQ) immediately after the program and after 1 and 3 months.

Material and Methods:

It was a single-blind, randomized controlled study. Subjects operated for CHD, in the age group of 8–19 years, were included in the study. Subjects in Group A received cardiac rehabilitation and RYM (Experimental group), whereas subjects in Group B received conventional cardiac rehabilitation (Control group).

Result:

At one-month follow-up, the experimental group showed a 14.18% reduction in RMR compared to baseline, whereas Group B showed 8.96% elevated RMR from baseline. Group A showed a more significant reduction in RMR at one-month follow-up from baseline as compared to group B (P < 0.05). The patients who underwent RYM training had higher PHBQ (−9.0 [−15.6, −2.5], P < 0.05) in comparison to the control group.

Conclusion:

The result of this study suggests that the inclusion of RYM along with conventionally given cardiac rehabilitation enhanced metabolic resilience with lowered resting metabolism and enhanced recovery post-surgery in children operated on for CHD. There was an improvement in the psychological adjustment and behavior of adolescents.

Published: August 2024

Amaç: Tele-sağlık ve teletıp SARS CoV-2019 (COVID19) pandemisi sonrasında adını daha sık duyduğumuz sağlık hizmeti sunumu uygulamalarıdır. Dünya Sağlık Örgütü tele-sağlığı “Bireylerin ve toplulukların sağlığını geliştirmek amacıyla mesafenin kritik bir faktör olduğu durumlarda bilgi ve iletişim teknolojilerini kullanarak hastalık ve yaralanmaların teşhisi, tedavisi ve önlenmesi, araştırma, değerlendirme anları ve sağlık hizmeti sağlayıcılarının sürekli eğitiminde geçerli bilgi alış-verişi için sağlık çalışanları tarafından sağlık hizmetlerinin sunulması” olarak tanımlamaktadır. Teletıp ise “bir hastanın klinik sağlık durumunu iyileştirmek için elektronik iletişim yoluyla bir taraftan diğerine tıbbi bilgilerin aktarılmasıdır” Teletıp aslında tele-sağlığın bir alt başlığı olmasına rağmen günümüzde bu iki sözcük anlamdaş olarak kullanılmakta ve daha çok kabul görmektedir. Bu yazıda amaç konuyla ilgili tanımları okuyucularla paylaşmak; ayrıca mezuniyet öncesi ve sonrası tıp eğitimi programlarında teletıp eğitiminin müfredatla bütünleştirilmesi ile ilgili örnek deneyimleri sunmaktır.
Gereç ve Yöntem: Geleneksel derleme yöntemiyle hazırlanan bu yazıda öncelikle teletıp ve ilişkili kavramların tanımları anlatılmıştır. Dünyadaki ve ülkemizdeki tarihsel sürecin paylaşılmasının ardından avantajları ve kısıtlılıkları tartışılmıştır. COVID-19 süreciyle ilişkisine değinilmiş ve bu durumun uzaktan sağlık hizmetleri sunumu konusunda tıp öğrencilerinin de bilgi ve deneyim sahibi olmaları gerektiği vurgulanmıştır. Teletıbbın tıp eğitimi müfredatındaki yeri örnek çalışmalarla paylaşılmıştır.
Bulgular: Sağlık hizmetleri sunumunda teknolojik olanakların kullanımı ve uzaktan sağlık hizmeti uygulamaları gelişmekte ve yaygınlaşmaktadır. Avantajları ve kısıtlılıkları ile teletıp bu gelişmelerin öncüsüdür. Tanı ve tedavi işlemlerinin yanında eğitim, danışmanlık, yönderlik; hatta uzaktan cerrahi girişimlerin yönetimi mümkündür. Öğrenci memnuniyetinin yanı sıra hastalar için de yaralıdır.
Sonuç: Tıp öğrencilerinin ve hekimlerin bu uygulamalar konusunda etkin bir kullanıcı olması, kendi personelleri ve hastalarının eğitimi konusunda önemli rol oynaması gerekmektedir. Zorunlu hallerde önemli hale gelen bu hizmet sunumu biçimi için öğrencilerin yüz yüze hasta yönetimi konusunda iyi yetişmiş olması gereklidir. Alan yazındaki örnek uygulamalar teletıp uygulamalarını ulusal ve uluslararası yeterlilik çerçevelerine uyarlamaya odaklanmıştır.

The Effect Of Simulated Patient Education On Critical Thinking Trends In Medical School Students
Authors: Özgün Ezgi , Şenol Yeşim
Published: August 2024

Introduction &Objective: Critical thinking consists of mental processes such as reasoning, analysis, and evaluation. It is an objective super-thinking way open to self-correction and change. The main component of the current education methods is the acquisition of critical thinking. Simulated patient applications in medical education is an effective method that enables the student to acquire cognitive and psychomotor behaviors with active participation in the learning process. The aim of this study is to determine the change in the critical thinking tendencies of the third-year students of Akdeniz University Faculty of Medicine before and after simulated patient applications.
Method: Third-year students of Akdeniz University Faculty of Medicine in the 2018-2019 academic year participated in the study. The students were asked to apply the Critical Thinking Disposition scale forms before the simulated patient applications. In the second stage of the study, the scale was reapplied to the students. The scale consists of 49 items. In our study, the results of the change between the first and the second applications of Critical Thinking Disposition scale were compared with the Paired Sample Test.
Results &conclusion: A total of 345 students participated in the study. The mean score obtained from the Critical Thinking Disposition scale of the whole group was 191.63 (SD = 21.07) in the fall term and 193.69 (SD = 23.63) in the spring term. Although there was an increase in mean values of CTHD scale, the difference was not statistically significant (t(344)=-1.09, p = 0.277). The multidimensional nature of critical thinking skills and the need for continuity in order to keep this skill sharp are considered effective on this result. Different applications can be added to the training program to develop this skill.
Sorption materials controlled by an external magnetic field for the purification of aqueous media from contamination
Authors: Горшенев В. Н. , Донцов А. Е. , Яковлева М. А.
Published: August 2024

В настоящее время в результате аварий при добыче, транспортировке и другим причинам происходит загрязнение окружающей среды и промышленных объектов различными вредными химическими веществами, в том числе нефтепродуктами. Поэтому для защиты природы от загрязнения, по-прежнему актуальна проблема разработки новых сорбционных материалов для локализации и сбора загрязнений, особенно эффективных для очистки водных сред. Новый подход решения этой экологической проблемы состоит в применении магнитоуправляемых сорбентов, а также, сорбентов на основе опилок, лигнина, лузги и т.д., обладающие большой сырьевой базой. В работе представлены результаты разработки технологии получения модифицированных углеродных дисперсных сорбционных материалов кластерами металлов и изготовления сорбционных конструкций для сбора и очистки водной поверхности от нефтяных загрязнений. Приводятся характеристики дисперсных углеродсодержащих сорбентов, полученных из отходов лесотехнических производств.

Currently, as a result of accidents during production, transportation and other reasons, the environment and industrial facilities are polluted with various harmful chemicals, including oil products. Therefore, to protect nature from pollution, the problem of developing new sorption materials for the localization and collection of pollution, especially effective for the purification of aqueous media, is still urgent. A new approach to solving this environmental problem consists in the use of magnetically controlled sorbents, as well as sorbents based on sawdust, lignin, husk, etc., which have a large raw material base.

В статье приведены полученные данные по выявлению влияния радиации и содержания радионуклидов в плаценте на развитие врожденных патологий у 124106 живорожденных детей в роддоме в возрасте от 0 до 6 дней. Также было исследовано 106 плацент рожениц, проживающих в урановой и без урановой зонах, на содержание урана и тория в золе плаценты с помощью нейтронно-активационного и рентгеноспектрального анализа. В I группе на наличие врожденных патологий было обследовано 8452 живорожденных ребенка в возрасте от 0 до 6 дней, матери которых постоянно проживают в г. Майлуу-Суу, т.е. в урановой биогеохимической зоне; также были обследованы 74 плаценты рожениц и их новорожденные дети. Во II группу (контрольную) вошли матери, постоянно проживающие в безурановой зоне в г. Ош. Обследованы 115654 живорожденных ребенка на наличие врожденных патологий, а также плаценты 32 рожениц и их дети. У детей, матери которых проживают в урановой зоне, врожденные патологии в возрасте до 6 дней выявляются в 2,9 раза чаще, чем у детей, матери которых проживают в безурановой зоне. Содержание урана и тория в золе плаценты было в 160 раз выше, по сравнению с образцами золы плаценты женщин из безурановой зоны.

The paper presents the data obtained on the identification of the effects of radiation and radionuclides in placenta on the development of congenital disorders in 124106 live-born children aged 0 - 6 days in the maternity hospital. Also, 106 placentas of women in labor, living in uranium and uranium-free zones, were examined for uranium and thorium in placental tissue ashes with the use of neutron activation and X-ray spectral analysis. In Group I, 8452 live-born children aged 0 to 6 days whose mothers permanently reside in Mailuu-Suu, i.e. in uranium biogeochemical zone, were examined for congenital disorders, 74 placentas of women in labor and their newborn babies were also subjected to examination. Group II (control) included mothers who permanently reside in a uranium-free zone in the city of Osh. A total of 115654 live-born children were examined for congenital disorders, as well as placentas of 32 women in labor and their babies. Congenital disorders in newborn children under 6 days are detected 2.9 times more often in newborns whose mothers live in uranium-polluted zone, than in newborns whose mothers live in uranium-free zone. Concentration level of uranium and thorium in placental tissue ashes was 160 times higher than that in placenta samples of women from the uranium-free zone.

В статье представлены результаты исследования содержания металлопорфиринов в составе сырой нефти из платформ № 8 и № 14 Гюнашлинского месторождения в Республике Азербайджан методами ИК-, УФ-спектроскопии и электронного парамагнитного резонанса. Этими методами в составе изученных образцов Гюнашлинской нефти не обнаружен металлопорфирин, являющийся биомаркером. Выявлено, что образцы нефти до и после гамма-облучения также не содержат металлопорфиринов. Этот показатель может использоваться при установлении генезиса нефти. Сделан вывод об абиогенном синтезе углеводородов Гюнашлинской нефти.

The article presents the results of a study of the content of metal porphyrins in the composition of crude oil from platforms No. 8 and No. 14 of the Gunashli oilfield in Republic of Azerbaijan using IR, UV spectroscopy and electron paramagnetic resonance. By means of these methods, it was not detected metal porphyrin, which is a biomarker in the composition of the studied samples of Gunashli crude oil. It was found that oil samples before and after gamma irradiation also do not contain metal porphyrins. This indicator can be used to determine the genesis of oil. A conclusion is made about the abiogenic synthesis of hydrocarbons from the Gunashli oil.

Кора акации ушковидной ( Acacia auriculiformis) , модифицированная разбавленными (1 - 3%) растворами азотной и фосфорной кислот, изучена в качестве биосорбента для удаления ионов Ni в статических условиях. Результаты проведенного исследования показали, что изотермы адсорбции ионов Ni на образцах нативной и модифицированной растворами кислот коры Acacia auriculiformis относятся к изотермам I типа, согласно классификации ИЮПАК и L-типу, согласно классификации Гильса. Максимальная сорбционная ёмкость нативной коры Acacia auriculiformis по ионам Niсоставляет 9,0 мг/г. Выявлено, что с увеличением концентрации растворов минеральных кислот, сорбционная ёмкость модифицированных образцов коры Acacia auriculiformis по ионам Ni увеличивается. Определено, что изотермы адсорбции наиболее адекватно описываются моделью Ленгмюра. Показано, что кинетическое уравнение псевдо-второго порядка достаточно хорошо согласуется с экспериментальными данными. Результаты расчетов термодинамических параметров (ΔH, ΔS и ΔG ) свидетельствуют о самопроизвольном протекании процесса физической адсорбции. При рассмотрении кинетических зависимостей в рамках диффузионной модели Бойда рассчитаны коэффициенты внешней и внутренней диффузии, а также критерий Био, значения которого для всех исследуемых процессов указывают на то, что лимитирующей стадией процесса является смешанная диффузия.

Acacia auriculiformis bark modified with weakly concentrated (1 - 3%) solutions of nitric and phosphoric acids has been studied as a biosorbent for the removal of Ni ions under static conditions. The results of the study show that the isotherms of adsorption Ni ions on samples of native and acid-modified bark of Acacia auriculiformis belong to type I isotherms, according to the IUPAC classification, and L-type, according to the Giles classification. The maximum sorption capacity of the native bark of Acacia auriculiformis for Ni ions is 9,0 mg/g. It was found that with an increase in the concentration of mineral acid solutions, the sorption capacity of modified Acacia auriculiformis bark samples for Ni ions increases. The obtained adsorption isotherms were processed within the framework of the Langmuir, Freindlich, Dubinin-Radushkevich and Temkin models. It has been determined that the adsorption isotherms are most adequately described by the Langmuir model. It is shown that the pseudo-second order kinetic equation is in good agreement with the experimental data. The results of calculations of thermodynamic parameters (ΔH, ΔS, and ΔG) testify to the spontaneous and endothermic nature of the adsorption process. Considering the dependency of the kinetic parameters in the framework of the Boyd diffusion model, the coefficients of external and internal diffusion were calculated, as well as the Biot criterion, the values of which for all the studied processes indicate that the limiting stage of the process is mixed diffusion.

В результате анализа образцов натурального пчелиного, термообработанного и искусственного меда была установлена обратная корреляция между токсическим соединением 5-гидроксиметилфурфуролом и пероксидом водорода, детектируемыми хроматографическим и спектрально-иодометрическим методами, соответственно. Показано, что повышение температуры обработки натурального меда приводит к снижению концентрации пероксида водорода и повышению уровня 5-ГМФ. Однако, во всех термообработанных образцах 5-ГМФ не превышал допустимый нормативной документацией предел - 25,0 мг/кг, даже при воздействии 80°С (16,1±0,6 мг/кг). В образцах искусственного меда наблюдалось незначительное содержание пероксида водорода (~0,000003 моль/л) и завышенная концентрация 5-ГМФ (118,8±4,1 мг/кг). Несмотря на то, что корреляционная зависимость между содержанием 5-ГМФ и пероксидом водорода не была линейной, снижение концентрации пероксида водорода свидетельствовало как о запрещенном термическом воздействии на мед, так и о факте фальсификации этого продукта.

As result of the analysis of the natural bee, heat-treated and artificial honey samples, the inverse correlation was established between the toxic compound 5-hydroxymethylfurfural and hydrogen peroxide, detected by HPLC and spectral iodometric methods, respectively. It has been shown that the increase in natural honey processing temperature leads to the decrease in the concentration of hydrogen peroxide and the increase of 5-HMF. However, 5-HMF didn’t exceed the limit allowed by the regulatory documentation - 25.0 mg/kg, even when exposed to 80°C (16.1±0.6 mg/kg), in all heat-treated samples. The insignificant content of hydrogen peroxide (~0.000003 mol/L) and the overestimated concentration of 5-HMF (118.8±4.1 mg/kg) were observed in the artificial honey samples. Despite the fact that the correlation between the content of 5-HMF and hydrogen peroxide wasn’t linear, the decrease in the concentration of hydrogen peroxide indicated both the forbidden temperature effect on the honey and the falsification of this product.
