Authors: Kamath Narayan , Das V K , Mahyavanshi Darshan , Vohra Mustafa
Published: September 2024

Dengue fever is a viral infection transmitted by mosquitoes and manifests in different forms, ranging from classic dengue fever to more severe dengue hemorrhagic fever.

: This study studies demographic, virological, clinical, hematological, and biochemical data, of dengue patient and their relationship with dengue fever type.

This study analyzed data from 178 confirmed cases of dengue infection in a tertiary care hospital Union Territory of Dadra and Nagar Haveli and Daman and Diu, India. Demographic data, clinical presentations, dengue serotypes, and biochemical and hematological profiles were collected and analyzed to understand the distribution of dengue virus serotypes and the severity of clinical manifestations.

The majority of patients were young males, with a mean age of 27 years. The prevalence of DENV-2 was significantly higher than that of the other serotypes, indicating its dominant circulation within the study population. The clinical features included fever (100%), headache (92.70%), myalgia (84.83%), and nausea/vomiting (64.61%). Hematological abnormalities were prevalent, including anemia (42.20% in males and 33.33% in females), thrombocytopenia (67.97%), and neutropenia (21.91%). Biochemical profiles showed elevated liver enzyme levels, with 75.84% of patients having elevated alanine aminotransferase levels. The results also showed that, as the severity of dengue fever increased, there were notable changes in hematological and biochemical parameters, such as decreased hemoglobin, hematocrit, platelet counts, elevated liver enzymes, bilirubin, and markers of renal function.

This study underscores the critical need for targeted public health strategies in regions with a high prevalence of DENV-2, and the importance of specific clinical markers in managing and predicting the progression of dengue. These insights could guide therapeutic interventions and public health measures, ultimately reducing disease burden.

Authors: Naz Ruby , Farooqui Mohammad Khalid , Hora Shilpi , Vijay Anubha
Published: September 2024

: Chronic suppurative otitis media(CSOM) is a chronic inflammation of the middle ear cleft characterised by persistent tympanic membrane perforation with intermittent or continuous purulent or mucopurulent discharge from the ear canal for more than 2 weeks to three months.

: We collected 249 growth isolates from patients of CSOM. We isolated and identified the common organism of CSOM and studied antibiotic susceptibility patterns.

: In our study, patient ages range from 1 year to 75 years. Most patients were male. the maximum number of patients (69%) were from age group 1-15. The most common organisms isolated were Spp (37%), followed by (30%) and (14%). Majority of Spp is were susceptible to Imepenem (100%), Piperacillin-Tazobactam (77%) and Amikacin (69%). Majority of the other Gram negative bacilli isolates were also susceptible to these antibiotics. Most of the Staphylococci were susceptible to linezolid and ofloxacin. 39% of Spp and 34% of were multidrug resistant (MDR).

Spp. followed by Staphylococcus Spp were the two common causative organisms of CSOM. Based on this study, suggestions for empirical antibiotics are Amikacin for gram negative bacilli and ofloxacin for Staphylococcus Spp.
La industrialización mexicana y la estructura económica entre 1950 y 1960
Authors: Aroche-Reyes Fidel
Published: September 2024

El presente trabajo tiene como objetivo primordial analizar algunos aspectos sobre la evolución de la estructura productiva mexicana durante la década de 1950 desde una perspectiva multisectorial. El punto de partida es el marco teórico y metodológico del modelo insumo-producto, lo que permite emplear algunas herramientas desarrolladas desde allí. La década en cuestión se caracteriza por el rápido desarrollo del sector manufacturero y el incremento del bienestar de la población, merced de la expansión de actividades con mayor productividad. Lamentablemente, la industrialización no bastó para absorber el exceso de fuerza de trabajo disponible. Quizá las políticas económicas pudieron haber orientado a la economía con ese objetivo.

The article examines effectiveness of organizing independent physical exercises for university students in a remote mode using a special mobile application. To achieve the purpose of the study, a pedagogical experiment was conducted with the participation of the second-year students of the Kuban State Agrarian University named after I. T. Trubilin. 80 students (40 men and 40 women) took part in this experiment, of which 2 experimental and 2 control groups were formed. During the pedagogical experiment, students of the experimental groups participated in the project “AgroFit”, aimed at organizing systematic independent physical exercises, including a competitive element, with the use of a special mobile application. The students of the control groups did not participate in this project. They engaged in elective classes in physical education and sports and during non-systematic independent training sessions. The analysis of the average amount of students’ physical activity per week showed that the participants of the project “AgroFit” had more than 2 times higher values of similar parameters typical for students who did not participate in it. According to the results of the experiment, the students in the experimental groups statistically significantly improved the values reflecting the level of their strength abilities and endurance. There were no statistically significant changes in the values of physical fitness indicators in the control groups of students. The results of the study showed significant effectiveness of using additional systematic physical activity of university students based on the use of information and communication technologies and carried out remotely to improve the level of their physical fitness.

Authors: Shirkani Pardis , Shirkani Afshin
Published: September 2024

This paper examines the impact of global warming on cancer development, specifically focusing on the intensified effects of environmental carcinogens such as ultraviolet (UV) radiation and air pollutants. Our review elucidates the intricate interplay between global warming, ecological carcinogens, human immunogenetics, and cancer susceptibility. The analysis highlights the exacerbating effects of rising temperatures and changes in atmospheric conditions on exposure to UV radiation and air pollutants, including particulate matter (PM), polycyclic aromatic hydrocarbons (PAHs), nitrogen dioxide (NO2), nitrogen oxides (NOx), and ground-level ozone (O3). Furthermore, the study explores the pivotal role of human immunogenetics in modulating individual responses to carcinogen exposure and shaping cancer susceptibility and progression. Genetic variations in key immune-related genes and their influence on the interplay between environmental carcinogens and cancer development are discussed. The paper underscores the importance of longitudinal cohort studies, integrative approaches, and interdisciplinary collaborations to advance our understanding of the complex interactions between global warming, environmental carcinogens, human immunogenetics, and cancer biology. Additionally, evidence-based public health interventions targeting environmental carcinogens and personalized prevention strategies based on genetic susceptibility profiles and environmental exposure assessments are proposed to address the growing challenges of environmentally induced cancers.
Family Structure and Female Enrollment into Engineering and Technology Programmes in English Speaking State Universities of Cameroon
Authors: Cheny Nfor, Julius , Nkepah Beyoh Dieudone
Published: September 2024

This study seeks to find out the influence of family structure composition and gender beliefs on female enrolment in to Engineering and Technology programmes in the English speaking state universities in Cameroon.  The methodology used in this study was an explanatory sequential mixed method design where data were collected from 276 students from the two universities and an interview administered to 10 parents whose children are enrolled in any engineering or technology department within the two English speaking state universities in Cameroon.  The data collection instrument was a structured questionnaire administered to the students and an interview guide administered to the parents. The data collected were analyzed descriptively and Point Biserial Correlation Analysis was also used to find the relationship between Family Structure Composition and Female Enrolment in Engineering and Technology Programmes. Paired Sample T-Test was also used to find out if gender within the family has an impact on enrolment in engineering and technology programmes and finally a Binary Logit Regression was used to show the impact of family structure on Female Enrolment in Engineering and technology Programmes. Findings from this study indicates that there is a weak relationship between family structure composition and female enrolment in engineering and technology. Indicating that performance in sciences and subsequent enrolment in engineering and technology by female students are supported by other factors other than the family structure. Paired sample T-Test and Binary logit regression analysis indicates a strong family belief system that female children should pursue the art discipline and this beliefs had a significant impact on female enrolment in engineering and technology fields. Parents should be encouraged to devote the same amount of their resources in educating their girl child as they do for the male children. House chaos and other constrains should be adequately managed within the family during school periods and negative family beliefs that have an impact on the schooling of the girl child should be avoided.

This paper seeks to throw light on the factors affecting nomadic pastoralists’ children’s education in Ghana. There has been little empirical research in Ghana on nomadic pastoralist education. This study was conducted in the Northeast region in an attempt to unpack the complex dynamics of culture, society, livelihoods, and region as barriers to nomads’ formal education. The study employed interviews, observations, and focus group discussions with students, including dropouts, parents, teachers, and Regional Education authorities, to understand the challenges confronting nomadic pastoralists’ access to education. Using the 4-A’s framework of accessibility, availability, acceptability, adaptability, and added affordability as the fifth variable. The study found that all the 5-A’s posed challenges to their access to education, in addition to cultural and religious values such as early marriage, protection of pastoral values, and poverty account for their inability to attend school.
O Ciclo Carolíngio e seu percurso da Península Ibérica
Authors: Morais Elisângela Coelho
Published: September 2024

O Ciclo Carolíngio constitui um compêndio de poemas medievais de autoria diversificada, elaborados em períodos distintos, que têm como tema central o imperador franco Carlos Magno e suas relações familiares, abrangendo antecessores, tios, sobrinhos, entre outros. Essas narrativas exerceram uma marcante influência na cultura medieval francesa, sendo concebidas a partir do século XI. Alcançaram significativo êxito ao atingir o público-alvo original, a nobreza, mas, além disso, desfrutaram de popularidade entre diversas camadas sociais, ultrapassando fronteiras geográficas e estendendo-se a outros países do continente europeu, notadamente à Espanha e a Portugal.

Authors: Barbosa e Silva Leonardo
Published: September 2024

Este artigo aborda o conjunto de desafios teóricos e metodológicos ainda não superados pelo campo científico que estuda o abandono na Educação Superior, aqui metaforicamente tratados como uma maldição. O objetivo foi sistematizar a contribuição da bibliografia que aponta as razões para que a longa trajetória teórica e aplicada não tenha alcançado o resultado esperado, qual seja a redução dos índices. Para tanto, foi utilizada a revisão narrativa da bibliografia, buscando colher contribuições em várias obras referenciais em quase um século de história do campo. Os resultados apontaram para a presença de desafios na definição do objeto (a falta de consenso e a inespecificidade). Mas também apontaram desafios metodológicos tais como a ausência de abordagem longitudinal, sistêmica e combinada de investigação qualitativa e quantitativa.

Authors: Chintu Sinam , Sarma Upasana , Yadav Akanksha , Sharma Luxita
Published: September 2024

Manipur is nestled in the northeastern part of India. The word Manipur means “land of diamonds” in Sanskrit. Jawaharlal Nehru, India’s first prime minister, referred to Manipur as the country’s “jewel.” It has a valley in the middle and is surrounded by nine mountain ranges. There are several different ethnic groups there. Because of its ethnic diversity and diverse landscape, Manipur is home to innumerable ethnic food that embodies the rich heritage and traditional flavors of the state. People from Manipur, among other things, have a propensity to consume a variety of leafy vegetables, which are common in the region. Amidst all the subsequent changes in eating patterns, Manipuri people continue to practice their culinary tradition. Traditional foods usually provide a good balance of bioactive compound and health benefits. The major ingredients of ethnic food have historically included rice, vegetables, fat (from ghee or oil) and some protein sources from traditional fermented soybean and fish. They are free from chemicals and abundant in nutrients like healthy fat, carbohydrate, vitamins and minerals. With the help of locally accessible vegetables, herbs and fermented food products, this review article aims to describe traditional knowledge of most popular food ingredients, therapeutic potential and nutritional properties of Manipur’s ethnic culinary culture.

Published: September 2024

Background: Plant growth regulators (PGRs) are widely used as pesticides that can induce toxicity to industrial workers and farmers directly by inhalation during use in agriculture and indirectly through food that have been sprayed with PGRs. Therefore, this work intends to investigate the protective and therapeutic effects of ginseng extracts against Trafos Cu induced kidney toxicity, DNA fragmentation, oxidative stress, and PCNA expression alterations. Methods: A total of 60 male rats divided into 6 groups [Gp1, control; Gp2, ginseng; Gp3, Trafos Cu; Gp4, Ginseng+ Trafos Cu; Gp5, Trafos Cu+Ginseng; Gp6, Self-treated. Result: Current findings revealed that rats treated with Trafos Cu (Gp3 and Gp6) induced a significant elevation in serum urea, creatinine, sodium, potassium, chloride and renal injury, DNA damage, MDA, PCNA, TNFα expressed and a significant depletion in calcium, GSH, and catalase levels as compared to control. Treatments of Trafos Cu with Ginseng (Gp4 and Gp5) induced improvements in kidney functions and structure with best results for Gp5. Ginseng has the capacity to mitigate the renal toxicity induced by Trafos Cu in male albino rats.

Authors: Krylov Pavel , Kuzmin P.A. , Melnik K.A.
Published: September 2024

Background: Gleditsia triacanthos L. is a valuable taxon for agroforestry. This species is promising for the creation of protective plantations and has a wide range of economically valuable traits, in particular, drought tolerance. In this regard, the aim of the work was to evaluate morphophysiological parameters of growth and development of G. triacanthos seedlings at early stages of ontogenesis under conditions of changing light intensity. Methods: To achieve this goal, seeds of G. triacanthos were sown with subsequent selection of individuals for the study possessing homogeneity of genetic structure. Analysis of close relatedness of individuals of G. triacanthos showed low intraspecific diversity by Nei (0.27 to 0.62). To evaluate the development of seedlings of G. triacanthos at early stages of ontogenesis, morphophysiological methods were used. Result: Under unfavorable conditions due to low light, the growth and development of the embryonic root and seedling formation was slow. However, all subphases of G. triacanthos seed organogenesis were passed in 98% of individuals, thus forming seedlings under standard criteria. Accumulation of total chlorophyll content in unfavorable conditions was 3 times less compared to individuals in favorable conditions. At the same time, there was a tendency to increase the sum of chlorophylls in the leaves of G. triacanthos in each experimental group at 30 days (p less than 0.05). As a result, it was revealed that light intensity is a limiting parameter for accelerated growth and development of G. triacanthos seedlings.

The focus of this activity is the application of the GOPP method to reading and speaking skills for German language teachers. Observation on the German language skills has been made of 40 respondents of German language teachers in Malang, East Java, Indonesia. The result indicates that teachers need to improve their language skills, especially reading skills and speaking skills in German. One of the methods for achieving this goal is the GOPP method (Goal-oriented project planning), which is an innovative pedagogy method of goal-oriented activity. This method has six phases of implementation: problem analysis, goal analysis, participants and potential analysis, project planning overview, action plan, and results analysis and documentation. In the action plan phase, the Schuppenfisch-technic is used. The results of the questionnaire show that this technique helps teachers in reading and writing skills. They enjoy the technic and they are self-confident when they are speaking in German. In addition, there is a plan to apply this method in the classrooms at their schools.
Keywords: GOPP-Method; reading; scaly fish; Schuppenfisch-technic; speaking skills.
Didáctica de la Filosofía en Colombia: Plurivocidad, Tensiones y Porosidad de un Concepto
Authors: Linares Oscar Javier
Published: September 2024

En este artículo de reflexión se presentan algunos de los resultados del proyecto de investigación Estado del arte sobre la didáctica de la filosofía en Colombia en el periodo 2010-2021. Allí nos propusimos elaborar un estado de la cuestión en torno a lo que se dice cuando se habla de didáctica de la filosofía en Colombia. El concepto didáctica de la filosofía fue reconstruido utilizando los insumos de la historia conceptual alemana, metodología que nos permitió eludir limitaciones puntuales de abordajes como la bibliometría y las categorías predefinidas y condensadas. Como resultado, destacamos la polisemia del concepto didáctica de la filosofía, descollando en el análisis tres de sus dimensiones: didáctica artefacto (sentido estrecho), didáctica no instrumental (sentido problematizador) y didáctica disciplinar (sentido amplio). Esta plurivocidad trae consigo cierta porosidad en las fronteras semánticas del concepto, por lo que subrayamos que se trata de un concepto móvil que hilvana diversas urdimbres con otros términos del campo. Nuestra hipótesis es que cada posible frontera semántica del concepto es dislocada por las tensiones intrínsecas a un campo o problema en emergencia en Colombia.

Published: September 2024

Este capíptulo investiga la naturaleza híbrida de El pasatiempo (1752-1753) de Antonio Joaquín de Rivadeneira y Barrientos, una obra que ha pasado desapercibida para la crítica literaria. En su trabajo, el autor muestra que el eclecticismo, en este caso representado por la variedad de formas y su naturaleza híbrida como prosímetro, corresponde a una propuesta estética original de un autor novohispano. Primero se ahonda en las circunstancias de la escritura de la obra y del autor a mediados del siglo XVIII y su impresión en Madrid mediante el análisis de la dedicatoria. Después se estudia la estructura y el género de la obra. Por lo tanto, el texto explica la naturaleza prosimétrica de este poema didáctico. Finalmente, se insiste en el diseño tipográfico novedoso, que implica una caja compleja con dos tipos distintos de notas a pie de página.

Em um contexto de desconfiança eleitoral, impulsionado, dentre outros fatores, por debates em plataformas digitais e aplicativos mensageiros, este estudo tem como objetivo mapear os enquadramentos conceptuais acionados em movimentos dialógicos ao longo do debate sobre fraude nas urnas no Brasil. Para isso, uma sintaxe de busca relativa ao tema foi executada na aplicação CrowdTangle (Meta, Inc.), no esforço de identificar o link sobre fraude nas urnas com maior engajamento no Facebook durante o pleito de 2022. Foram analisados os comentários ao link, bem como as respectivas respostas, que tiveram o maior número de interações, o que gerou um corpus de 363 comentários e respostas. A partir da análise, conclui-se que na interação dos usuários da plataforma a segurança da urna eletrônica é colocada em uma disputa partidária de “direita versus esquerda” e, ainda, são construídos sentidos que classificam as universidades públicas negativamente, como espaço de “balbúrdia” contrário às regras socialmente instituídas. Nota-se, com isso, que o processo de enquadramento conceptual da urna eletrônica evoca vozes diversas, nem sempre relacionadas à urna em si, refletindo traços de moralidade e recusa às instituições.

he study of dropout has become of vital importance and nowadays special attention is being paid to it. In the definition of strategies to help reduce this problem, there is a need to define school dropout and dropout, as well as to make an exhaustive reflection on the causes that originate it, in order to generate actions to support students at all educational levels, according to their real needs and in a prompt and equitable manner.Dr. Ragueb Chaín Revuelta proposes to differentiate between the terms desertion, abandonment and expulsion, since they have different implications when talking about the causes that lead students to stop their studies at different educational levels and contexts. Dr. Chaín places special emphasis on how the causes are often determined by the configuration of the person who studies them, attributing their origins to the vision of the researcher's profession. Likewise, he urges to investigate the subject using current tools, such as artificial intelligence, to have a more concrete picture, avoiding the incorporation of too many variables in school trajectories. He recommends "that school administrators and directors responsible for educational programs have an attitude for early identification of risks".
FINITE APPROXIMATION OF NONCOOPERATIVE 2-PERSON GAMES PLAYED IN STAIRCASE-FUNCTION CONTINUOUS SPACES
Authors: Romanuke Vadim

Finite approximation of noncooperative 2-person games played in staircase-function continuous spaces
Background. There is a known method of approximating continuous noncooperative 2-person games, wherein an approximate solution (an equilibrium situation) is considered acceptable if it changes minimally by changing the sampling step minimally. However, the method cannot be applied straightforwardly to a 2-person game played with staircase-function strategies. Besides, the independence of the player’s sampling step selection should be taken into account.
Objective. The objective is to develop a method of finite approximation of 2-person games played in staircase-function continuous spaces by taking into account that the players are likely to independently sample their pure strategy sets.
Methods. To achieve the said objective, a 2-person game, in which the players’ strategies are staircase functions of time, is formalized. In such a game, the set of the player’s pure strategies is a continuum of staircase functions of time, and the time is thought of as it is discrete. The conditions of sampling the set of possible values of the player’s pure strategy are stated so that the game becomes defined on a product of staircase-function finite spaces. In general, the sampling step is different at each player and the distribution of the sampled points (function-strategy values) is non-uniform.
Results. A method of finite approximation of 2-person games played in staircase-function continuous spaces is presented. The method consists in irregularly sampling the player’s pure strategy value set, finding the best equilibria in “smaller” bimatrix games, each defined on a subinterval where the pure strategy value is constant, and stacking the equilibrium situations if they are consistent. The stack of the “smaller” bimatrix game equilibria is an approximate equilibrium in the initial staircase game. The (weak) consistency of the approximate equilibrium is studied by how much the payoff and equilibrium situation change as the sampling density minimally increases by the three ways of the sampling increment: only the first player’s increment, only the second player’s increment, both the players’ increment. The consistency is decomposed into the payoff, equilibrium strategy support cardinality, equilibrium strategy sampling density, and support probability consistency. It is practically reasonable to consider a relaxed payoff consistency.
Conclusions. The suggested method of finite approximation of staircase 2-person games consists in the independent samplings, solving “smaller” bimatrix games in a reasonable time span, and stacking their solutions if they are consistent. The finite approximation is regarded appropriate if at least the respective approximate (stacked) equilibrium is -payoff consistent.
Adaptive control at the channel level of the packet radio networks with a rigid strategy for accessing the radio channel
Authors: Voiter Anatolii
Published: September 2024

Background. Development of methods and means of the adaptive management control of the bandwidth radio networks with competitive access to the radio channel.
Objective.
Determination of the effect of packets length on the effective transmission speed of radio networks taking into account the parameters, formats and procedures of the physical and channel levels when using six possible strategies of the adaptive CSMA protocol with a rigid strategy of competitive access to the radio channel.
Methods.
The goal is achieved by creating and analyzing a mathematical model of effective transmission speed in radio network. The model is described by the equation of the effective transmission rate, which is a function of the probability of conflict-free transmission of the adaptive CSMA protocol for rigid strategy and the deviation coefficient of the size of data packets from the optimal LLC protocol, taking into account the probability of packet damage due to interference in the radio channel.
Results.
With the help of this mathematical model, it is proved that of the six packet length management strategies for adaptive CSMA protocols with a rigid strategy, only the first, third and sixth strategies have practical significance from the point of view of increasing the effective transmission speed, provided that the influence of the parameters of the physical and LLC levels is taken into account. For these strategies can be calculated according to this model the optimal size of the length of data packets for each set of system parameters, such as the transmission speed, the probability of damaging one bit of information due to interference in the radio channel, and the structure of the packet of the LLC protocol.
Conclusions.
The proposed mathematical model is a tool for calculating the bandwidth of radio networks and the optimal size of data packets during adaptive management of competitive access to a radio channel with a hard strategy in conditions of significant fluctuations in traffic intensity and changes in the intensity of interference in the radio channel.
INFLUENCE OF CARBONATE TYPE ON TRANSPORT CHARACTERISTICS OF SiC-BASED CERAMIC MEMBRANES
Authors: Molchan Yuliia , Zelenska Anastasia , Yanushevska Olena , Dontsova Tetiana
Published: September 2024

Background. Ceramic membranes have recently attracted particular attention due to their thermal and chemical resistance, ability to be used in aggressive environments, and long service life. Among ceramic membranes, silicon carbide membranes deserve special attention due to their high strength. However, the high cost of such membranes and the controllability of porous characteristics, which significantly affect the transportation characteristics, remain an unresolved problem. Therefore, it is extremely important to investigate ways to reduce the annealing temperature of SiC membranes and control their porosity.
Objective. The aim of this work is to determine the effect of the type of carbonate on the physicochemical properties and transport characteristics of ceramic membranes based on silicon carbide. The ceramic membranes were obtained by pressing, to which borax (to reduce the annealing temperature) and carbonates (as a pore forming agent) were added.
Methods. Method of pressing and sintering with different composition of carbonates. Analysis of the obtained ceramic membranes by the diffraction method and scanning electron microscopy.
Results. It has been shown that the addition of sodium carbonate results in the formation of a new phase, sodium aluminosilicate, while no new phases were detected when ammonium bicarbonate was used. The morphology of the synthesized ceramic membranes has a granular structure characterized by pores ranging in size from 13 to 21 μm and a specific surface area of 1.5–1.9 m3/g. The investigated transport characteristics of ceramic membranes indicate that the use of ammonium bicarbonate allows to obtain a ceramic membrane with a sufficiently high throughput, which can be recommended for use in the field of microfiltration.
Conclusions. Ammonium bicarbonate is a more promising pore-forming additive for ceramic membranes based on silicon carbide. Further research will focus on studying the effect of the defoamer content on the transport and mechanical properties of ceramic membranes.

Background. Environmental pollution with plastic waste is a global problem that requires the search for effective and safe ways of disposal or processing of secondary raw materials. The use of catalysts for this purpose is a promising direction for research.
Objective. In this work, a method of introduction of nanomaterials on the surface of a polyethylene film by partially dissolving the upper layer of the polymer in a heated nanomaterial suspension, namely aluminosilicate halloysite nanotubes in cyclohexane, was developed. 
Methods. Thermogravimetric, optical, and dynamic mechanical analyses of synthesised samples were carried out, and their properties were compared with reference samples of pure polyethylene and treated without the addition of nanomaterial. 
Results. It was achieved by the introduction of halloysite nanotubes in the amount of a maximum of 2.83 % by mass after immersion of the film in the suspension at a temperature of 50 °C for 120 seconds. The resulting film showed a wetting angle value of 77.11o, while for the reference sample without HNT it was 99.24o, which indicates the presence of hydrophilic nanotubes in the PE surface layer. 
Conclusions. At the same time, the synthesised samples showed a significant decrease in mechanical properties, such as elasticity and tensile strength, due to the destructive effect of the solvent on the polymer.

Rozprawa doktorska Karola Marcinkowskiego (1800-1846) zatytułowana „De fontibus indicationum generatim” została opublikowana w 1823 r. w Berlinie jako pierwsza polska praca z zakresu filozofii medycyny. Jej autor był polskim lekarzem praktykującym w Poznaniu, wtedy w zaborze pruskim, szanowanym za patriotyzm i działalność dobroczynną dla najuboższych chorych. Rozprawa jest pierwszą polską pracą z zakresu historii medycyny, jednak dotychczas nie była przetłumaczona z łaciny na polski. Komentarz dostarcza pewnej wiedzy o rozprawie i jej autorze.

Artykuł przedstawia początki i rozwój opieki sanitarno-epidemiologicznej w Katowicach przed 1945 r. Na początku XX w. Śląsk znajdował się na terytorium Niemiec, dlatego pierwsze instytucje zajmujące się zdrowiem publicznym, w tym identyfikacją, zapobieganiem i leczeniem chorób zakaźnych, utworzono na podstawie niemieckich przepisów. Po pierwszej wojnie światowej przeprowadzono wśród ludności śląskiej plebiscyt, na podstawie którego Śląsk, w tym Katowice, został włączony do Polski. Zasadnicza Ustawa Sanitarna z 1919 r. była podstawą organizacji pierwszej państwowej instytucji sanitarnej, która w 1923 r. została przekształcona w Państwowy Zakład Higieny. W artykule przedstawiono w ogólnym zarysie działalność PZH w okresie międzywojennym, a także inne polskie i niemieckie instytucje służące zwalczaniu chorób zakaźnych przed 1945 r.

This study aims to analyze consumption behavior of students of Department of Islamic Economics of University of Islam Indonesia, particularly class of 2012, whether it is in accordance with the Islamic perspective or not and how the studentsâ€™ social environment does affect the consumer behavior. This study applies descriptive quantitative analysis which is done by choosing 50 respondents aged between 20-24 year old as sample based on Purposive Sampling method. The writer also uses questionnaires in gathering the data and double linear analysis technique in processing the data. In this study, the writer finds that the consumer behavior of the Ekis FIAI UII students, particularly class of 2012, has actually been in accordance with the principle of aqidah, amaliyah, and spirituality, even though it has not yet represented the simple and modest principle. According to â€˜tâ€™ test, it shows that the adherent group variable has no significant influence to the Islamic consumer behavior of the 2012 Ekis students since the value of â€˜tâ€™ is smaller than the table of â€˜tâ€™, which is 0.728 < 2.011. The value of â€˜tâ€™ of the family variable is about 2.506, meaning that family has significant impact towards Islamic consumer behavior. From the independent variables, it is found that the adherent and family variable do not significantly influence the Islamic consumer behavior. The adjusted R square is 0,133, meaning that 13,3% of the Islamic consumer behavior of 2012 Ekis students is affected by family.

Published: September 2024

A trademark serves as the identity of a product, aimed at distinguishing one product from the other producers’ product. In Indonesia, there is a protection for trademark owners, governed by Law No. 20 of 2016 on Trademarks and Geographical Indications. The main principles used in the protection of rights to a trademark are the constitutional principle and the first-to-file principle. The study is about the legal protection of rights to a trademark over the "GOTO" brand ownership dispute between PT Terbit Financial Technology and PT GoTo Gojek Tokopedia. This study uses a normative legal research method with approaches based on legislation and conceptual frameworks. According to the conducted research, the "GOTO" trademark owned by PT GoTo Gojek Tokopedia should not exist and its registration should not have been accepted because Indonesian trademark law adheres to the constitutional principle and the first-to-file principle. Legal protection, therefore, allows PT Terbit Financial Technology to file a trademark infringement lawsuit and/or a trademark cancellation. Consequently, the authorities responsible for enforcing rights to a trademark protection are expected to perform their duties effectively to prevent future brand ownership disputes.Keywords: Trademark, Legal Protection, GOTO
