PERFIL DE RESISTÊNCIA BACTERIANA EM SUPERFÍCIES DE TELEFONES CELULARES DE ESTUDANTES DE UMA INSTITUIÇÃO PRIVADA DE ENSINO SUPERIOR DO AGRESTE PERNAMBUCANO
Authors: VILAR DE OLIVEIRA MARIA GABRIELA , DE SIQUEIRA BRAGA MARIA GABRIELLA , CAVALCANTI DE ALBUQUERQUE ANA CECÍLIA
Published: November 2024

Os telefones celulares são amplamente utilizados e frequentemente entram em contato com o rosto, mãos e pele, criando um ambiente propício para a colonização microbiana. Estudantes universitários, especialmente aqueles na área da saúde, estão expostos a uma maior contaminação de seus celulares por microrganismos patogênicos, aumentando o risco de infecções. Objetivo: Determinar o perfil de resistência bacteriana em superfícies de celulares de estudantes de um Centro Universitário do Agreste Pernambucano. Metodologia: O estudo apresenta uma abordagem quantitativa, descritiva, do tipo experimental laboratorial. Foram realizadas coletas das superfícies dos celulares dos alunos do curso de Biomedicina de uma instituição privada de ensino superior no Agreste Pernambucano, por meio da fricção de swabs embebidos em meio Stuart. Após a coleta das amostras e de algumas informações relacionadas aos cuidados com o celular, as amostras foram semeadas em ágar sangue, ágar MacConkey, em meios bioquímicos e realizado a coloração de Gram. Após a identificação, foi realizado o antibiograma para determinar o perfil de resistência bacteriana utilizando os discos de Ampicilina, Vancomicina, Amoxicilina, Clindamicina, Azitromicina e Novobiocina, sendo este último para diferenciação de Staphylococcus epidermidis e Staphylococcus saprophyticus. Resultados: Até o momento foram analisados 24 celulares, onde 12 tinham a presença do Staphylococcus epidermidis; 10 com Staphylococcus saprophyticus, 01 com Staphylococcus aureus e 01 com Serratia liquefaciens. Em relação ao antibiograma, 75% das amostras apresentaram resistência à Azitromicina. Apenas 62,5% dos proprietários dos celulares coletados faziam a higienização com álcool, sendo que a maioria, 40%, realizava essa higienização apenas mensalmente. Entretanto, o uso deste dispositivo é prolongado, pois 75% dos estudantes o utilizavam por mais de 5 horas por dia e 76,6% dos proprietários afirmaram compartilhar os celulares com outras pessoas.  Todos os alunos informaram que os levavam para diversos lugares, como banheiro, cozinha, sala de jantar, laboratórios/hospitais, entre outros. Conclusões: Os resultados deste estudo evidenciaram a alta prevalência de contaminação bacteriana nos celulares dos estudantes de Biomedicina do Centro Universitário do Agreste Pernambucano. A presença significativa de Staphylococcus epidermidis e Staphylococcus saprophyticus, assim como cepas resistentes à antibióticos, destaca a necessidade urgente de medidas preventivas. A prática insuficiente de higienização dos dispositivos móveis, aliada ao seu uso prolongado e compartilhamento frequente, contribui para um risco elevado de disseminação de microrganismos patogênicos.

Authors: LEMOS FONTES SILVA COSTA LUÍS HENRIQUE , CAVALCANTE NETO PAULO , ARTEIRO FILGUEIRA NORMA
Published: November 2024

O tabagismo permanece como um relevante problema de saúde pública, levando a mortes e altos custos de saúde. Na última década, foi observado um aumento do consumo de formas alternativas de tabagismo, especialmente cigarros eletrônicos. Embora sejam falsamente percebidos como menos danosos à saúde pela população geral e até mesmo por profissionais de saúde, tais produtos podem determinar risco semelhante ou até maior que o do cigarro convencional, tendo sido descrita uma nova entidade clínica, conhecida como EVALI, que consiste em sintomas constitucionais, gastrointestinais e infiltrado pulmonar bilateral, e levou a hospitalização em 95% dos casos, ventilação mecânica em 26% dos casos e dois óbitos. Objetivo: Determinar a frequência de tabagismo e do uso de cigarros eletrônicos e analisar as atitudes para cessação do tabagismo entre médicos residentes. Metodologia: Foi realizado um estudo transversal incluindo 53 médicos residentes de especialidades clínicas do Hospital das Clínicas da Universidade Federal de Pernambuco, usando um questionário eletrônico preparado pelos autores, baseado em instrumentos utilizados em estudos prévios, como a Global Health Professional Students Survey e a Global Adult Tobacco Survey. Foram avaliados hábitos sobre o uso de cigarros convencionais ou eletrônicos e conhecimentos e atitudes a respeito da cessação do tabagismo. Resultados: Do total de 92 residentes matriculados em programas de especialidades clínicas, 53 responderam ao questionário (57,6%). Na amostra avaliada, 13 (24,5%) participantes referiram já terem experimentado cigarros convencionais em algum momento da vida, dos quais 6 (11,3%) referiram uso atual; enquanto 17 residentes (32,1%) já experimentaram cigarros eletrônicos e 4 (7,5%) ainda usavam regularmente. Todos os fumantes atuais informaram também o uso prévio ou atual de cigarros eletrônicos.  45 residentes (84,9%) relataram não se sentirem adequadamente treinados no aconselhamento para cessação do tabagismo, embora 37 (69,8%) já tivessem prescrito alguma droga para tal. Embora a totalidade da amostra tenha considerado que todo profissional médico deve ter conhecimentos básicos sobre a cessação do tabagismo, 11 participantes (20,4%) relataram questionar com baixa frequência seus pacientes sobre o hábito de fumar e 25% nunca investigavam o uso de cigarros eletrônicos. Dez residentes (18,9%) informaram não ter conhecimento sobre EVALI. Conclusões: As taxas de tabagismo encontradas em médicos residentes ainda foram altas, reforçando a necessidade de intervenções educacionais nesta população. Intervenções são necessárias para melhorar o ensino sobre estratégias de cessação do tabagismo durante o curso de medicina e os programas de residência.

Published: November 2024

A min-plus algebra is a linear algebra over the semiring R_ε', equipped with the operations “"⊕'=min" ” and “⊗=+”. In min-plus algebra, there is the concept of characteristic polynomial obtained from permanent of matrix. Min-plus algebra can be extended to an interval min-plus algebra, which is a set 〖 I(R)〗_ε' equipped with the operations ¯("⊕'" ) and ¯("⊗" ). Matrix over interval min-plus algebra has some special forms, one of which is a triangular matrix. The concept of characteristic polynomial and eigenproblem can be applied to a triangular matrix. There is a more concise formula for solving the eigenproblem of triangular matrix because this matrix is a special form of matrix. This research will discuss the characteristic polynomial and solving eigenproblem of triangular matrix over interval min-plus algebra using its characteristic polynomials. The research method used is a literature study. From the research results, the permanent formula and characteristic polynomial formula of the triangular matrix are obtained. It is also obtained that the smallest corner of the characteristic polynomial is the principal eigenvalue and the vector eigen corresponding to the principal eigenvalue can be obtained through the matrix A_λ. For readers who are interested in this topic, can research about characteristic polynomial and eigenproblem of matrices with other special forms over min-plus interval algebra.

Published: November 2024

This research aims to apply the Generalized Space-Time Autoregressive (GSTAR) model to predict stock price indices in ASEAN-5 countries. Generalized Space Time Autoregressive (GSTAR) model is one of the most common used space-time model to modeling and predicting spatial and time series data. The GSTAR model produces a space-time model that adopts the stages of the Autoregressive Integrated Moving Average (ARIMA) model. This research uses parameter estimation using the Maximum Likelihood method, which is a method used to estimate parameter values by maximizing the probability function seen based on observations. This research uses secondary data in the form of Stock Price Index data from 5 countries in Asia, namely the Composite Stock Price Index (JCI), Philippine Stock Exchange (PSEi), Strait Time Index (STI), Kuala Lumpur Composite Index (KLCI), and Thailand Stock Exchange Index (SETI). Stock Price Index data was divided into in-sample data for Generalized Space-Time Autoregressive (GSTAR) modelling and out-sample data used to validate presumptive results. In-sample data was taken from January 4, 2021, to December 29, 2023, and then out-sample data for presumptive was as many as 5 from January 2, 2024, to January 8, 2024. From the modeling results, it was found that the mean MAPE value of the GSTAR model was smaller than that of the ARIMA model. Moreover, based on the presumptive results for the following 5 periods using the GSTAR (2.1) I(1) model, a Mean Absolute Percentage Error (MAPE) of less than 10% in each location. The values shows that GSTAR model is more accurate than the ARIMA model.

Published: November 2024

This study aims to evaluate the effectiveness of the Chi-Square feature selection method in improving the classification accuracy of linear Support Vector Machine, K-Nearest Neighbors and Random Forest in natural language processing when combined with classification algorithms as well as introducing Pseudo-Labelling techniques to improve semi-supervised classification performance. This research is important in the context of NLP as accurate feature selection can significantly improve model performance by reducing data noise and focusing on the most relevant information, while Pseudo-Labelling techniques help maximise unlabelled data, which is particularly useful when labelled data is sparse. The research methodology involves collecting relevant datasets, thus applying the Chi-Square method to filter out significant features, and applying Pseudo-Labelling techniques to train semi-supervised models. In this study, the dataset used in this research is the text data of public comments related to the 2024 Presidential General Election, which is obtained from the Twitter scrapping process. The characteristics of this dataset include various comments and opinions from the public related to presidential candidates, including political views, support, and criticism of these candidates. The experimental results show a significant improvement in classification accuracy to 0.9200, with precision of 0.8893, recall of 0.9200, and F1-score of 0.8828. The integration of Pseudo-Labelling techniques prominently improves the performance of semi-supervised classification, suggesting that the combination of Chi-Square and Pseudo-Labelling methods can improve classification systems in various natural language processing applications. This opens up opportunities to develop more efficient methodologies in improving classification accuracy and effectiveness in natural language processing tasks, especially in the domains of linear Support Vector Machine, K-Nearest Neighbors and Random Forest well as semi-supervised learning.

Authors: Tundo Tundo , Yel Mesra Betty , Nugroho Agung Yuliyanto
Published: November 2024

Beef is considered a high-value commodity because it is an important food source of protein. Interest in beef is increasing along with increasing people's incomes and awareness of the importance of fulfilling nutrition. Demand for beef is expected to continue to increase. According to the Central Statistics Agency (CSA), beef production in Jakarta shows an increasing trend every year. In the last 10 years, beef production has increased significantly, but in 2020 there was a decrease in production of 7,240.68 tons due to the lockdown due to the corona virus outbreak. After that, in 2021, production reached 16,381.81 tons and will continue to increase in 2022 and 2023. Based on the above phenomenon, the aim of this research is to support the success and sustainability of the beef industry by ensuring that supply matches demand, resources are used optimally, and risks can be managed well. To predict beef production, an accurate method, model or approach is needed. One way to predict beef production in Jakarta is to use the Linear Regression and Double Moving Average (DMA) methodsThe way the Linear Regression and DMA methods work is to forecast based on concepts and properties. The concepts and properties of Linear Regression are models, functions, estimates and forecasting results, while DMA performs time series analysis based on moving averages. After analysis using MAPE, it was found that the algorithm that had the smallest error value was the linear regression algorithm with a percentage for the monthly period of 15% while for the year period it was 17% compared to DMA. So in this case it would be very appropriate to use the Linear Regression method from the error values obtained.

Authors: Mukhaiyar Utriweni , Dianpermatasari Aprilia , Dzakiya Azizah , Widyani Sasqia Bunga , Syam Husnul Khatimah
Published: November 2024

The insurance has often been involved to minimize financial losses. As the product providers, the insurance companies must effectively manage risks to prevent errors in risk measurement. The amount of risk or loss experienced by the policyholder refers to the claim amount. The Value at Risk (VaR) is commonly used to measure risk. The VaR is calculated from the probability function, which can be obtained by evaluating the distribution of claims data. Most claim frequencies are small, but occasionally, huge claims appear. Therefore, the appropriate distribution would be characterized by a heavy-tailed. Thus, this research aims to model and evaluate insurance claims data using exponential, Weibull, Pareto, and lognormal distributions to assess financial risk through VaR. The insurance claims data were collected from a single insurance company and include 1,326 claims. This research specifically examines variables such as gender, diabetic status, smoking status, the number of claims, and the level of confidence. The data were analysed using descriptive statistics, Maximum Likelihood Estimation for parameter estimation, and Goodness of Fit tests to determine the best-fitting distribution, along with VaR calculations based on the results. The suitability of the distribution model is assessed through the VaR and is analysed based on the appropriate distribution of insurance claims data. It is obtained that the Weibull and lognormal distributions appropriately model insurance claims data. The highest VaR is observed in the claim data for female non-diabetic smokers, with a level of confidence of 99.5%. The lowest VaR is obtained from the claim data for male diabetic non-smokers, with a level of confidence of 90%. This approach enhances the prediction of large potential losses for specific demographic groups, aiding more informed decision-making in premium pricing and risk management. The integration of heavy-tailed distributions in risk assessment, with a particular focus on demographic specificity, constitutes a substantial and novel contribution to this research.

Given two players with the first player is called A and second player is called B coloring vertex of graph G with a set of colors C={c_1,c_2,c_3, ..., c_k}. A must to make sure that all vertex of G has colored and B must try to prevent A coloring of all vertex. The first step was taken by A as first player, two players take turns coloring vertex of graph G, with rule that every vertex have different color from the neighbourhood. If all vertex of graph G have been colored, then A win or B win if some vertex hasn’t colored. The smallest number of k if A has a strategy to win at graph G with k color, then k called game chromatic number which is denoted by χ_g (G). The strategy to win this game is coloring the biggest degree of vertex in graph first. The result obtained from this paper is A win the game with the strategy of first coloring the largest degrees of vertex. So, exact of game chromatic number of tadpole graph is 3, broom graph is 2 or 3 with several conditions, and tribune graph is 3 or 4 with several conditions.

Published: November 2024

Integrating values into all aspects of the learning process for a particular subject is an important part of education. Students must not only develop cognitively, but the formation of attitudes and characters must also be in line with the overall educational goals. Mathematics, as one of the core subjects that students must learn, must also reflect the values embedded in it. The success of mathematics education can be assessed through the values conveyed during the learning process. This study aims to explore and analyze teachers' understanding of Mathematical Values and Values in Mathematics Education, as well as how these values are conveyed in the classroom. This study aims to explore and analyze teachers' understanding of Mathematical Values and Values in Mathematics Education, as well as how these values are conveyed in the classroom. This study uses a qualitative approach with a case study design. Data were collected through interview techniques from 4 mathematics teacher informants determined by percussive sampling techniques. Data analysis uses an intractic model in line with the data collection process through three activities simultaneously; (1) data condensation; (2) data display, and (3) drawing conclusions/verification. The results of the study indicate that teachers' understanding of Mathematics values [rational values] and Mathematics education values are very important in improving students' logical thinking skills, and providing a comprehensive understanding of mathematics in developing their problem-solving skills. In mathematics teaching practices, teachers convey mathematical values during problem-solving activities, where students must understand various mathematical equations, concepts, and methods. While Mathematics education values (MEV) are conveyed during the problem-solving phase and reinforced at the end of the teaching and learning activities.

The present study is aimed at creating catalytic systems based on magnetite (Fe3O4) stabilized by polymers (polyvinylpyrrolidone (PVP) and chitosan), for liquid-phase oxidation of organic compounds with gaseous oxygen in order to obtain oxygen-containing compounds that can be used in the production of dyes, synthetic fibers, drugs, and many other petrochemical products. Magnetic composites of Fe3O4 stabilized by PVP and chitosan were synthesized by the coprecipitation method. The prepared magnetic composites were studied by physicochemical analysis methods. It was found that surface stabilization with polymers leads to a decrease in the size of magnetite nanocrystallites in nanocomposites. The sizes of the studied composites are less than ∼ 10 nm. Mössbauer spectra of the obtained Fe3O4, Fe3O4/PVP, and Fe3O4/chitosan composite catalysts showed the presence of trivalent iron ions in a tetrahedral environment and the presence of Fe2+ and Fe3+ in an octahedral environment, as well as a doublet spectrum. The possibilities of using magnetite-based composite catalysts for heterogeneous liquid-phase oxidation of para-xylene with oxygen are considered. Based on the analysis of the IR spectra of the final reaction samples, the presence of CH bonds in the aromatic ring and C=C double bonds, as well as valence vibrations of the C=O group of carbonyl compounds and vibrations of the bonds of hydroxyl groups was established. It is shown that the main products of the oxidation reaction of p-xylene are p-toluyl aldehyde and dibutyl phthalate, which can be widely used for basic organic synthesis. The authors concluded that the magnetic composite of the Fe3O4/PVP composition can be used to produce oxygen-containing compounds, in particular, toluyl aldehyde and dibutyl phthalate.
Plume Rise from a Stack Based on the Volkov Formula
Authors: Shalkouhi P. Jafari , Atabi F. , Moattar F. , Yousefi H.
Published: November 2024

Plume rise from most sources is an important factor in determining ground-level concentration of air pollutants. Various attempts have been done to compute plume rise from stationary sources. Volkov (1979) proposed a formula for calculation of plume dimensions (height and length) from a stack, while most of the well-known plume rise equations can only compute plume rise or plume height. Both plume height and plume length should be determined in some cases, for example in study of stack and cooling tower plume mergence, plume behavior (lofting, fanning, coning, looping, trapping and fumigation) etc. Because there are little studies in the world regarding the accuracy of the Volkov equation, the aim of the present work is to investigate the validity of the Volkov formula based on 5 statistical tests including the relative error, mean square error, root mean square error, coefficient of determination and Nash-Sutcliffe coefficient. The results revealed that (1) the Volkov equation better predicts plume rise at the distance of 60 m than 30 m from a typical stack, (2) considering the value of 0.5 instead of 0.4 or 0.65 for n in the Volkov formula will lead to more accurate results and (3) plume dispersion pattern was categorized as lofting. Overall, the Volkov equation can be an acceptable method to study of plume rise; nevertheless more studies must be conducted in the future with regard to the accuracy of the Volkov formula.

The integration of Building Information Modelling (BIM) and Geographic Information Systems (GIS) is becoming increasingly important in the construction industry and urban planning, helping to create smart cities and digital twins. The research, which involved expert interviews, and an online survey conducted among specialists from partner countries, shows that there is a significant skills gap, as many professionals lack expertise in combining BIM and GIS. It also indicates that while the integration of these technologies is advancing, it is still in the early stages. To tackle this issue, the BIRGIT project—featuring partners from Sweden, Italy, Spain, Belgium, and Croatia—aims to develop new educational programs that meet market demands. Ongoing initiatives like BIRGIT are vital for bridging the skills gap and ensuring that professionals are well-equipped to effectively implement these technologies, ultimately improving project management and decision-making in the industry.

This paper explores pedestrian mobility patterns in Kypseli, a dense and socio-economically diverse neighborhood in Athens, Greece, that it is considered as a typical Greek residential area, in terms of its built environment and road network characteristics. The research method included crowdsourced geospatial data overlayed on cadastral maps, and semi-structured interviews with residents and visitors to understand the routes they usually take, the routes they could take, and the routes they would like to take. The study also applied space syntax analysis, using angular integration and choice tools, to assess how the urban layout impacts the pedestrian flow. Findings showed that the walking routes are primarily influenced by safety, accessibility, and pavement width, with well-connected streets and streets with intense mixed land-use. The study highlights the importance of urban design and land management in promoting the perceived walkability. It also recommends enhancing pedestrian spaces to create more sustainable, livable, and socially inclusive cities to support the implementation of the Sustainable Development Agenda 2030 SDG 11.

The current stage of genetic certification of horses of factory and local breeds based on microsatellite analysis makes it possible to quite effectively carry out identification and genetic examination of the origin of breeding animals, as well as solve the problem of assessing and preserving genetic resources. With a reduction in the number of breeding stock to 200–300 mares, observed in a number of breeds, the threat of a decrease in the genetic diversity of populations and the accumulation of genetic load increases, which necessitates the need to study and monitor the genetic structure of horse breeds. In this regard, our comparative genetic analysis of polymorphism of 17 microsatellite loci in 20541 horses of 30 factory and local breeds allows us to certify the basic part of the genetic resources of the horse breeding of the Russian Federation. including riding, trotter, draft and local breeds. During the genetic population analysis of the studied breeds, basic parameters were assessed: the total number of allele variants (Na), the effective number of alleles (Ae), the average number of alleles per locus (MNA), the level of observed (Ho) and expected heterozygosity (He), as well as the coefficient of intrapopulation inbreeding Fis. Phylogenetic relationships of breeds were assessed using the R and R Studio software packages. Among horse breeds of different specializations, the highest values of all indicators of genetic diversity (Ae, Ho, He and Na) were determined in aboriginal populations. In the allele pool of local horse breeds, there were rare alleles ASB2T, HMS7S, HMS6J, HMS6H, HMS2T, HMS1O, HTG7L, HTG6L, HTG6H, VHL20S, ASB17Z, ASB17X, ASB17U, LEX3S, LEX3R and CA425E, which were absent in horses of factory breeds. Among the riding horse breeds created in Russia, the Budennovsk, Don and Kabardian horse breeds stood out due to the presence of rare alleles. Alleles ASB2G, ASB2F, HMS2F, HTG7Q and ASB23O were found in trotter horses, which were not identified in the genetic structure of other breeds. The phylogenetic analysis showed the division of horse breeds into two clear subclusters, the first of which included only factory breeds. The second cluster united all the native breeds, as well as the Orlov trotter and a group of draft breeds, which were used for many years as improvers of the local horse population. The analysis of the genetic structure of domestic horse breeds revealed a fairly high reserve of diversity even in small populations, which is an indispensable condition for successful selection in horse breeding.

Using the next-generation sequencing (NGS) technology, the nucleotide polymorphism in a fragment of the ND4 gene encoding NADH dehydrogenase subunit 4 was studied in 14 samples from three populations of the bird cherry-oat aphid (Rhopalosiphum padi L.) and the range of nucleotide polymorphism was determined. The insects were collected in 2021 and 2022 in the North-West of Russia (in the vicinity of St. Petersburg) and in the northern Caucasus (Krasnodar Territory and Dagestan). Mitochondrial DNA haplotypes were identified, which have 97.95–99.80% sequence identity with the reference GenBank accession number KT447631.1. The level of intraspecific polymorphism of a 438 bp ND4 gene fragment in Rh. padi varied from 0.2 to 4.3%. In the two-year experiments, 33 polymorphic sites (17 transitions and 16 transversions) were found in the ND4 sequences, which made it possible to identify 30 mitochondrial DNA haplotypes. The Rh. padi populations collected simultaneously on different host plants or at different times on bird cherry (spring) and cereals (summer) differed in the proportion of the main haplotype, as well as in the composition of unique minor haplotypes. Analysis of the ratio of mitochondrial DNA haplotypes suggests the important role of the host plant genotype in the formation of the structure of Rh. padi populations.

The thermoreceptor gene TRPM8 (rs7593557) was analyzed in 15 population samples living in different regions of Northern Asia, the Altai-Sayan Highlands and Canada. High frequencies of a rare genotype and allele in the populations of the Altai-Sayan region and Western Siberia were found among the Telengits (22.2 and 41.7% respectively), low among the Siberian Tatars (3.2 and 18.5% respectively), and among the peoples of northern Siberia and the Far East high frequency was found among the Nanais (22.2 and 42.6% respectively), and a low frequency among the Yakuts (1.1 and 10.9% respectively). No deviations from Hardy-Weinberg equilibrium were found. Trans-association of TRPV1, TRPA1 and TRPM8 gene polymorphisms was carried out using the regression analysis method in 14 populations. Of all three pairs, only one, TRPV1/TRPM8, showed a positive correlation (0.55, df = 13, P-value – 0.032). In pairs TRPV1/TRPA and TRPA1/TRPM8, a negative correlation was revealed (–0.545, df = 13, P-value – 0.048) and (–0.46, df = 13, P-value – 0.097) respectively. Our data indicate that the studied polymorphisms of the TRPV1 and TRPM8 genes are correlated with each other and negatively correlated with TRPA. The results obtained may indicate the coevolution of these genes. It was previously shown that TRPV1, as well as TRPM8, was detected with high frequency in the Nanai population. It is likely that these two mutations came simultaneously from East Asia and spread throughout Russia, which explains the fact that they are positively correlated with each other.

Triticum militinae Zhuk. et Migusch. – tetraploid wheat with the GAA genome, considered a natural naked mutant of T. timopheevii Zhuk. Previously, experiments were conducted for this wheat to study the karyotype and crossing characteristics. To clarify its origin and relationship with other representatives of the wheat family, analysis of the chloroplast genome of T. militinae, which has previously remained unstudied, is of great interest. The sucrose gradient method was used to isolate chloroplast DNA from leaves. Sequencing was performed using the FASTASeq 300 Sequencing Kit V1.0 100 M reads/flow cell on a Genolab M sequencer (GeneMind, China). For the first time, we sequenced and annotated the complete chloroplast genome of T. militinae with a size of 135898 bp. In the structure of the plastid genome there are a pair of inverted repeats with a size of 21552 bp each, the region of a small single copy (SSC) – 12791 bp and the region of a large single copy (LSC) – 80003 bp. As part of the chloroplast genome of T. militinae 132 structural genes were found, of which 85 protein-coding genes, 31 tRNAs and 4 rRNA genes.
