Authors: Trebino Molteni Juan Manuel , Rodríguez Leticia I. , Paitampoma Álvarez Pablo , Campoverde Imbaquingo Francel
Published: April 2024

El osteocondroma es el tumor óseo benigno más frecuente, representa el 35% de los tumores óseos benignos y el 8% de los tumores óseos. Está formado por una exostosis de hueso trabecular recubierta de cartílago que afecta la región metafisaria de los huesos largos, a partir del cartílago de crecimiento, alrededor de la rodilla, en el hombro o la muñeca, y es extremadamente raro en las falanges de la mano o el pie. Crece durante la niñez y la adolescencia hasta alcanzar la madurez esquelética; por lo tanto, su crecimiento en un adulto sugiere la transformación maligna en condrosarcoma, aunque también existen reportes sin malignización. Además, el calcáneo es un hueso corto, por lo que, desde el punto de vista fisiopatológico, sería inesperada la aparición de este tipo de lesión. El objetivo de este artículo es presentar un caso de osteocondroma de calcáneo solitario con crecimiento después de la madurez esquelética, su diagnóstico y tratamiento, así como una revisión bibliográfica. Esta presentación de caso es importante, dados la localización infrecuente y el potencial de transformación maligna del osteocondroma, y laescasa bibliografía sobre el tema.

The Global New Woman and the Invention of Modern Feminism
Authors: Selbin Jesse Cordes
Published: April 2024

New Woman literature is typically regarded as an Anglo-American invention, but this assessment ignores the contributions of global authors who shaped the genre's rise in the decades before its more familiar Western emergence. This essay demonstrates that in the late nineteenth century, Indian women authors crafted both fictional and nonfictional writings that anticipate, expand, and complicate standard narratives of the New Woman. These understudied texts—by authors like Toru Dutt, Krupa Satthianadhan, Shèvantibāi Nikambé, and Rokeya Sakhawat Hossain—also centrally shaped mainstream Indian feminism while occluding alternative counterstrains. New Woman literature and the wider feminist movement cannot be understood without analyzing these transnational incarnations; indeed, I argue, both had transimperial origins. The works analyzed here reframe early feminism as an international enterprise—one more diverse and global in scope than most existing scholarship recognizes.
Passing as White Collar: The Black Typewriter and the Bureaucratization of the Racial Imaginary
Authors: Avery Tamlyn
Published: April 2024

The typewriter—the machine and the human operator at the nadir of the white-collar hierarchy—became associated with white female workers in the American racial imaginary. Although the color line deterred Black applicants from that side of the collar line, the Black typewriter as a literary type came to salience between 1886 and 1930, disrupting what I call the “bureaucratization of the racial imaginary”: the process whereby the exclusionary white middle-class tenets underpinning the bureaucratized office both regulated and were also informed by the imaginative possibilities of race, gender, and labor. Tracing the Black typewriter from Pauline Elizabeth Hopkins and Charles W. Chesnutt to Jean Toomer and Dorothy West, I reveal how these authors construed white-collar identity as a form of racial passing, requiring the worker's acceptance of racial and sexual segregation. Their innovative narratives about passing as white collar foregrounded the Black typewriter's unsettling experiences inside that system, challenging the theory that economic uplift would inherently promote racial and sexual equality.
History of the Czechoslovak Tourist Society between 1938–1948
Authors: Tlustý Tomáš , Kursová Vlastra
Published: April 2024

The present paper focuses on one of the less known Czechoslovak tourist organisations. The Czechoslovak Tourist Society was formed relatively late in comparison with the other tourist organisations active in Czechoslovakia, namely in the year 1925. Its membership consisted mainly of members of the middle and lower walks of life of the nation. Accordingly, its primary objective was to offer the less well-off classes cheap participation in group tours, visits to natural beauties of Czechoslovakia or recreational stays in spas, all at minimal membership fees. The membership base of the Czechoslovak Tourist Society had gradually grown, reaching as many as 30 thousand members in the period under review. Its members were involved in resistance activities during the Nazi occupation. The Society intended to follow up on its approach to occupiers after the end of the war, when they attempted to gain the leading role among Czechoslovak tourist associations, which increasingly discussed the creation of a unified Czechoslovak tourist organisation. The Czechoslovak Tourist Society lost its independence in 1948, when it was – like other Czechoslovak physical education, sports and tourist organisations – incorporated into Sokol by communists.

Published: April 2024

Research demonstrates that 45% of Europeans do not participate in physical activity, and unhealthy lifestyle habits acquired during college years can persist into adulthood. Undertaking physical activity brings many benefits but also a greater likelihood of overload and injuries. The use of effective injury prediction methods enables the screening of the population, contributing to its greater awareness when engaging in physical activity, reducing the occurrence of injuries, and, consequently, influencing the health of society. The aim of this study is to examine the relationship between the level of physical activity and the functional fitness of students and to assess the risk of injuries related to physical activity. A total of 114 students (44 women and 70 men) aged 19-23 took part in the research. A physical activity level test (International Physical Activity Questionnaire-IPAQ) and a Functional Movement Screen (FMS) test were performed. In most subjects, movement patterns are disturbed due to asymmetries and functional compensations that require preventive measures and compensatory exercises. The risk of injury, estimated based on the FMS assessment, is 25-35%. Compared to female students, male students achieve, onaverage, better results in test samples classified as mobility patterns (MP); male students have better results in stability patterns (SP). Significant relationships are observed between intense physical activity and lateral stabilization patterns of the pelvis, trunk, and hips (FMS 2), trunk stabilization (FMS 6), and stability patterns (SP). Moreover, total physical activity shows a significant positive correlation with the trunk stability push-up.
IMPROVING INDUSTRIAL SAFETY AT DELAYED COKING UNITS
Authors: Bakhonina Elena I. , Akhmadeev Ruslan R.
Published: April 2024

A significant part of the installations of oil refineries are hazardous production facilities and are characterized by the presence of a large amount of flammable substances that can form explosive mixtures with air. One of such units is a delayed coking unit (DCO). The ultrasonic treatment plant plays an important role as part of a refinery, increasing the depth of oil refining (up to 98%) and contributing to the production (along with coke) of large volumes of light oil products and gas. The action of a number of dangerous factors can lead to depressurization/destruction of equipment, as well as to the failure of flange connections of devices and pipelines, seals of pumps and fittings, and to the release of hazardous substances. The article provides information about a number of registered accidents that occurred at ultrasonic testing facilities in Russia, as well as their causes. In the analyzed cases, there were human errors. Particular attention should be paid to the training of ultrasonic testing operators, on whose actions the stable functioning of the technological process depends. The plant operator must be actively involved in the management of the production cycle, which requires a thorough understanding of not only how the plant operates, but also the ability to anticipate potential problems and respond in a timely manner to problems that arise. Often, classical methods of training personnel for emergency situations show insufficient effectiveness, so the solution to the problem is seen in strengthening the rules of industrial safety when working at ultrasonic testing facilities, and practicing skills through training on specialized computer simulators. To date, there is no information in open sources on simulators specifically for delayed coking units. The authors considered aspects of the formation of the technical specifications and architecture of the simulator for ultrasonic testing operators with an emphasis on industrial safety and response during an emergency. A block diagram of a virtual training complex for ultrasonic testing has been proposed.

EXPERIMENTAL DETERMINATION OF THE VOLUMETRIC HEAT TRANSFER COEFFICIENT IN COOLING TOWERS WITH VERTICAL CONTACT DEVICES
Authors: Kryuchkov Dmitry A. , Ivanyakov Sergey V.
Published: April 2024

Intensification of heat and mass transfer processes in industrial drop cooling towers is one of the main areas of research in modern heating engineering. Increasing the efficiency of transfer processes during the direct interaction of water and air in cooling tower sprinklers is possible when moving from creating a contact surface in the form of a flowing liquid film to sprinklers creating drop-film surfaces. One of the possible devices that create such surfaces are devices with vertical contact grids, which make it possible to obtain significant drop surfaces at low energy costs. A mathematical description of mass and heat transfer processes in devices with vertical grids is impossible without the presence of functional dependencies of mass and heat transfer coefficients depending on the hydrodynamic parameters of the process. Obtaining analytical expressions convenient for engineering modeling is difficult due to the complexity of the mathematical description, therefore in some cases it is more convenient to use experimental dependences of the coefficients on the process parameters. The experiments carried out on mass and heat transfer in devices with vertical grids made it possible to confirm the possibility of using the Lewis relation, based on the similarity between the processes of heat and mass transfer under conditions of water cooling in cooling towers equipped with devices with vertical grids. This made it possible to use only one experimental dependence in the mathematical description of transfer processes. An experimental dependence of the volumetric heat transfer coefficient on the hydrodynamic parameters of the interaction of water and air on the contact grids was also obtained.

Published: April 2024

Experiments for treating soil contaminated with oil and petroleum products using electric current in laboratory conditions using graphite and ruthenium titanium electrodes were carried out. The main purpose of the study was to study the dynamics of temperature changes during soil treating. The obtained and analyzed results allowed us to draw conclusions about the influence of various factors on the soil treating and the efficiency of using graphite and ruthenium titanium electrodes. The greatest resistance is observed in the central zone of the electrochemical cell. Closer to the electrodes, the resistance decreases, which contributes to a more efficient electrochemical treating process in these areas. Modern methods of data analysis, including statistical analysis and visualization of results, were used in the work, which made it possible to obtain more accurate and reliable results and draw conclusions about the possibility of using this technology for practical purposes.

Authors: Pavlova Zukhra Kh. , Dudnikov Nikolai Yu. , Azmetov Khakim Kh. , Azmetov Khasan A.
Published: April 2024

Currently in the oil and gas industry, the most common is the underground pipeline laying. Underground pipeline laying is also used in water-saturated soils. When water-saturated soil freezes, due to ice expansion, a force acts on the pipeline outer surface. This force leads to the appearance of compressive hoop stress in the pipeline wall and can lead to the pipe wall stability loss. For various reasons, there may be water in the cavity of an underground pipeline laid in water-saturated soil. Due to negative temperatures and water-saturated soil freezing, ice will be formed in the soil, as well as in pipeline cavity. In this case, the expansion force of ice in pipeline cavity creates internal pressure on the pipe, alongside with a ring tensile stress. The expansion force of ice in the soil creates external pressure on the pipe with the occurrence of hoop compressive stress. The need to ensure environmental safety of pipeline system operation in the oil and gas industry involves assessing the strength of an underground pipeline laid in water-saturated soil and containing water in the pipe cavity under the influence of ice expansion forces.The aim of research: ensuring environmental safety based on assessing the strength and stability of the pipeline wall due to ice expansion forces.Object of research: environmental safety, pipeline or its sections under the influence of ice expansion forces.Research methods: theoretical studies of the stress-strain state of pipelines in water-saturated soil containing water in the pipe cavity during the onset of sub-zero temperatures, when the pipes are exposed to external and internal ice expansion forces.Analytical expressions are obtained to determine the pressure on the surface of a pipeline laid in water-saturated soil and containing water in the cavity due to ice formation in the soil and in the pipe cavity.

Enhancing cryptographic robustness with dual key chaining
Authors: Muhammad Faisal Nawaz , Yasir Nawaz
Published: April 2024

In this paper, we introduce an advanced mode of operation for block ciphers, named Dual Key Chaining Mode (DKC), aimed at bolstering cryptographic security for safeguarding sensitive information. Building upon the foundations laid by established modes while adhering to guidelines set by the National Institute of Standards and Technology (NIST), DKC innovates through a dual-key mechanism and the generation of highly unpredictable values. This novel approach markedly enhances security, particularly against chosen plaintext attacks, a common vulnerability in traditional modes. Through rigorous mathematical analysis, we demonstrate DKC’s superiority, proving its indistinguishability under chosen plaintext attacks (IND-CPA) and showing that an adversary cannot practically distinguish DKC-encrypted ciphertexts from those produced by a random permutation. Our security proof employs a structured approach, contrasting DKC with conventional modes to highlight its robust defense mechanisms and its capacity to mitigate error propagation, reduce chain dependency, and resist pattern recognition attacks. The DKC mode not only surpasses existing standards in cryptographic security but also offers significant improvements in efficiency and security complexity, making it particularly suited for environments demanding stringent data protection. This study’s findings underscore DKC’s potential as a leading candidate for securing communication channels, financial transactions, and cloud storage services against an array of cryptographic attacks.

Authors:   Solla S.A., Restrepo-Rojas Oliver , Múnera-Bedoya Oscar D ,   Solla S.A., Giraldo-Mejía Angel M ,   Universidad Nacional de Colombia, Quiñones-Segura Libardo ,   Solla S.A.
Published: April 2024

Background: A typical broiler production program includes three feeding phases: Pre-starter (from day 1 to 10), Starter (11-21 days), and Grower (from day 22 to slaughter). The program should allow the bird to express its genetic potential and respond to the nutritional challenges. Objective: To determine the effect of duration of the starter and grower phases on growth performance parameters (feed intake and feed conversion), mortality, skin pigmentation, and carcass yield in broiler chickens. Methods: A total of 1,500 Ross 308 AP male broilers were randomly assigned to five feeding programs with different duration, feed presentation (pellet vs. crumble), and anticoccidial (narasin + nicarbazin vs. salynomicin). The variables evaluated were growth performance (body weight, feed intake, and feed conversion), carcass (weight and yield), breast weight and yield, and skin pigmentation. Statistical evaluations were conducted on d 28 and 40 of age. Results: On d 28 of age, differences (p<0.05) were observed for body weight and feed conversion, but not for feed intake. T4 and T5 resulted in the best weight and feed conversion. Differences (p<0.05) were recorded on d 40 for body weight, with higher values in T4 and T5 compared to T1. Carcass weight differed between T1 and T4 (p<0.05), without difference for carcass or breast performance. The statistical analyses of carcass pigmentation showed an effect on redness (“a”) and yellowness (“b”) at d 28. Conclusions: Body weight and feed conversion of broilers from d 22 to 28 improve by extending the starter phase one week, using pelleted feed added with an ionophore anticoccidial. Skin pigmentation of broilers at slaughter is not affected by restricting pigment intake for one week.
TAPER-WE: Transformer-Based Model Attention with Relative Position Encoding and Word Embedding for Video Captioning and Summarization in Dense Environment
Authors: Himanshu Tyagi Et al.
Published: April 2024

In the era of burgeoning digital content, the need for automated video captioning and summarization in dense environments has become increasingly critical. This paper introduces TAPER-WE, a novel methodology for enhancing the performance of these tasks through the integration of state-of-the-art techniques. TAPER-WE leverages the power of Transformer-based models, incorporating advanced features such as Relative Position Encoding and Word Embedding. Our approach demonstrates substantial advancements in the domain of video captioning. By harnessing the contextual understanding abilities of Transformers, TAPER-WE excels in generating descriptive and contextually coherent captions for video frames. Furthermore, it provides a highly effective summarization mechanism, condensing lengthy videos into concise, informative summaries. One of the key innovations of TAPER-WE lies in its utilization of Relative Position Encoding, enabling the model to grasp temporal relationships within video sequences. This fosters accurate alignment between video frames and generated captions, resulting in superior captioning quality. Additionally, Word Embedding techniques enhance the model's grasp of semantics, enabling it to produce captions and summaries that are not only coherent but also linguistically rich. To validate the effectiveness of our proposed approach, we conducted extensive experiments on benchmark datasets, demonstrating significant improvements in captioning accuracy and summarization quality compared to existing methods. TAPER-WE not only achieves state-of-the-art performance but also showcases its adaptability and generalizability across a wide range of video content. In conclusion, TAPER-WE represents a substantial leap forward in the field of video captioning and summarization. Its amalgamation of Transformer-based architecture, Relative Position Encoding, and Word Embedding empowers it to produce captions and summaries that are not only informative but also contextually aware, addressing the growing need for efficient content understanding in the digital age.

A Journey to ‚German Prague‘. Gertrud Fussenegger’s Travelogue 'Bohemian Enchantments' ["Böhmische Verzauberungen", 1944]
Authors: Meid Christopher
Published: April 2024

A travelogue is one of the most popular literary genres in the Third Reich. It can display escapist tendencies as well as be used for ideological propaganda. This is the case in Gertrud Fussenegger‘s travelogue Böhmische Verzauberungen [Bohemian Enchantments, 1944], which legitimises the ‘Germanisation’ of Prague with reference to the ‘Reich’ idea and at the same time, based on a description of the Jewish cemetery in Prague - develops an anti-Semitic phantasmagoria. The article analyses how Fussenegger’s text uses cultural-historical descriptions of central places of memory to substantiate German hegemony.

Published: April 2024

Scorpion venoms contain different classes of molecules with possible pharmacological activities, making them sources of bioactive molecules for the development of new drugs against infections caused by pathogens, such as malaria, a disease caused by protozoa of the genus Plasmodium. Malaria faces challenges in its control due to pathogen resistance to available antimalarials.

In this study, we evaluated the venom activity of the Amazonian scorpions and against FRC3, the analysis was performed by flow cytometry.

At the analyzed concentrations, we found that the crude venom of had an average inhibition of 87% at the concentration of 100 µg/mL, above that obtained with the drug (quinine), which had mean inhibition of 84% against FCR3. Regarding the venom of , lower activity was observed in comparison with the inhibition potential of the venom and the standard drug, venom showed low toxicity against the human fibroblast MRC5.

Because peptides and toxins from scorpion venom are related to biological functions, they can be used in the design of new therapeutic agents, with venom being a possible source of molecules for the development of antimalarial drugs.
A comparative study of clinical symptoms, demographic characteristics and laboratory parameters among primary and secondary dengue cases in a tertiary care hospital in Kolkata

Published: April 2024

Dengue, an arthropod borne viral disease which is transmitted to humans through the bite of infected Aedes mosquitoes, can result in a range of clinical presentations from mild febrile illness like dengue fever (DF) to severe presentations like dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS) which can turn fatal.While majority of primary dengue cases are asymptomatic/ mild symptomatic, secondary dengue infected cases usually have more complications and require critical care support.

To find out proportion of Dengue IgG among NS1 reactive cases, study their clinical-demographic profiles and to find out the prevalent dengue serotypes.

Blood collected from patients suffering from acute febrile illness less than 5 days and more than 5 days duration were tested for Dengue NS1and Dengue IgM respectively. Samples reactive for Dengue NS1 were further tested for dengue IgG by ELISA and dengue serotyping by RT-PCR. Results obtained were analysed and interpreted.

Out of 2286 blood samples suspected for Dengue during the study period (March 2021 to February 2022), only 134 samples were NS1 reactive and amongst them, 21 (16%) had early detection of IgG antibodies while the rest 113(84%) cases were primary dengue infection. The predominant serotype was DENV-3.

It is evident that patients who suffer from Secondary Dengue infections require more supervision and critical care support. This highlights the importance of Dengue IgG detection in the early phase of the disease in order to predict the complications of dengue which can save many more lives. Nevertheless, Primary dengue infections can also be severe, hence should be monitored closely under supervision. Molecular surveillance may help to predict large scale outbreaks of dengue if regional shifts in the predominantly circulating serotypes are detected during the early phase of the dengue season.

Materials and Methods: A cross-sectional study with a purposive sampling method was applied using pre-tested close-ended questionnaires and laboratory data (soft copies/hard copies) of participants admitted to hospitals or nursing homes within the North -24 Paraganas district from November 2021 to October 2022. 110 male and female patients of 40-60 years reported dengue fever (non-hospitalized cases), and dengue hemorrhagic fever (hospitalized cases) was considered based on 15 variables. STATA version 18.0 software analyzed data using multivariate regression and range plots.

The Cronbach’s alpha value was 0.72, and the consolidated probability value shows 0.01 (p<0.05), which denotes that the multivariate model was statistically significant and was rightly decided to include the relevant independent variables. Calcium, vitamin D, and total protein were statistically significant as P values were 0.01, the same for each. Similarly, p=0.05 was the same for Total Leukocyte count (TLC) and Alkaline phosphatase (ALP).

The study concludes that micronutrients like calcium, protein, vitamin D, etc., are often considered secondary recommendations in dengue treatment. A balanced, nutrient-rich diet for dengue patients is needed to maintain sustained immunity by extensively monitoring calcium, vitamin D, and total protein intake during and after recovery.

This case report highlights the diagnostic intricacies and clinical implications of pelvic hydatidosis, particularly in the context of the Indian healthcare system. Despite being a rare occurrence, pelvic hydatidosis presents significant challenges in diagnosis and management, necessitating a comprehensive approach for optimal patient care. The case involved a 54-year-old male presenting with right thigh pain and a gradually enlarging groin and thigh swelling. Imaging studies revealed a large cystic lesion with multiple internal cysts extending into the pelvic cavity, suggestive of pelvic hydatidosis. Following confirmation of pelvic hydatidosis, the patient received a 7-day course of albendazole prior to undergoing surgical excision via laparotomy. The cystic mass located in the right thigh's medial aspect was successfully removed, with subsequent peritoneal irrigation and uneventful postoperative recovery. Oral albendazole was prescribed for 6 months, and at the 6-month follow-up, no signs of disease recurrence were observed. Histopathological examination confirmed the diagnosis, showcasing characteristic features of hydatid cysts. The rarity of pelvic hydatidosis compared to other forms of echinococcosis underscores the importance of maintaining a high index of suspicion, especially in regions where the disease is endemic. The complex socioeconomic landscape in India, characterized by poor sanitation and limited healthcare access, contributes to delayed diagnosis and increased morbidity rates.

Breast carcinoma is the most common malignancy among women globally. FNA is used as an important diagnostic tool as a part of triple assessment. The application of the IAC Yokohama system in breast cytology standardises reporting and also allows the calculation of risk of malignancy (ROM).

To categorize all FNAC specimens according to the newly proposed IAC Yokohama reporting system for breast cytology. The ROM was determined for each category, sensitivity, specificity, negative and positive predictive values were evaluated to estimate the diagnostic accuracy of each category and inter-observer variability.

105 cases of breast FNACs were classified according to the IAC Yokohama system. The study was conducted over a period of 4 years and 9 months retrospectively from August 2018 to May2023. All FNACs were correlated with corresponding histology, but in most studies correlation of FNACs with histopathology was not possible in all cases because many were lost to follow-up. ROM for each category, Specificity, sensitivity, diagnostic accuracy, negative predictive value, positive predictive value and interobserver variability of FNAC were calculated. p-value was also calculated.

Out of 105 breast FNACs, the category wise distribution from category 1 to 5, were category 1:4(3.8%), category2: 20(19.1%), category3: 16(15.2%), category4:5(4.8%) and category 5: 60(57.1%) respectively. The sensitivity, specificity, positive and negative predictive value and diagnostic accuracy was 90.3%, 100%, 100%, 82.5% and 93.3% respectively.

: The Yokohama system has standardized, broadly used, and well-understood diagnostic categories, with clear criteria for inclusion in a category and appears to be reproducible by most cytopathologists.

The COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has posed significant challenges worldwide, with India being one of the most affected countries. Understanding the clinical variables, complications, and laboratory markers associated with COVID-19 progression is crucial for effective management and reducing mortality.

This retrospective study aimed to analyze the clinical characteristics, complications, comorbidities, and laboratory markers associated with COVID-19 progression among patients admitted to SPM Hospital, India.

Clinical data of 440 confirmed COVID-19 patients admitted between June and December 2020 were analyzed. Demographic characteristics, clinical symptoms, comorbidities, laboratory findings, and radiological manifestations were reviewed. Patients were categorized based on age, gender, comorbidities, and disease severity.

The study cohort comprised mainly elderly patients, with more than half aged 50-80 years and a male predominance. Fever, cough, and sore throat were the most common symptoms, with a significant proportion of patients presenting with comorbidities such as diabetes mellitus and hypertension. Laboratory markers including interleukin-6 (IL-6), D-dimer, C-reactive protein (CRP), serum ferritin (S. ferritin), and lactate dehydrogenase (LDH) were elevated in severe cases, with higher levels observed in patients aged ≥50 years. Patients requiring oxygen supplementation had a higher mortality rate compared to those maintaining oxygen saturation on room air.

Age, gender, and comorbidities were identified as risk factors associated with COVID-19 severity and mortality. Elevated levels of IL-6, D-dimer, CRP, S. ferritin, and LDH were indicative of disease severity and poor prognosis. Early identification of high-risk patients and personalized management strategies are essential for improving clinical outcomes in COVID-19 patients.
A study on delayed cord clamping and early skin-to-skin contact and its effect on maternal health

Before the mid-1950s, Early Cord Clamping (ECC) meant clamping the umbilical cord within one minute of birth. Delayed Cord Clamping (DCC), on the other hand, involved clamping the cord more than five minutes after birth. After birth, because of noticing changes in blood volume and the absence of clear guidance on the best timing, early cord clamping became a usual practice, typically happening within 15-20 seconds of birth.

The objective of the study is to identify the effects of DCC and early skin-to-skin contact on mother’s physiological parameters, breastfeeding behaviour, and post-partum haemorrhage compared to Early Cord Clamping.

A group of 300 mothers and their newborns were studied after the mothers agreed to participate. The mothers were split into two groups, each with 150 participants. Group A experienced DCC and ESS contact, while Group B had Early Cord Clamping.

The study's results showed similar findings in both groups regarding the average Hb level and maternal blood loss. Postpartum haemorrhage was less among DCC compared to early group with significant difference was observed.

This study discovered that DCC with ESSC has a positive impact on preventing postpartum haemorrhage. This is achieved through improved breastfeeding and bonding. The study found that the side effects of DCC and ESSC are not significant. So, DCC and ESSC should be practiced in term uncomplicated deliveries.

The article presents the results of a study of the elemental composition, surface morphology, optical and electronic properties of Mg2Si thin films formed on Si (111). Both samples containing films were formed in layers by the method of reactive epitaxy, but at different heating temperatures of the substrates. The formed films consisting of alternating layers of Mg and Si at a ratio of 3:1, according to electron Auger spectroscopy, contain Mg and Si atoms in the associated layers. The Raman light scattering method established the presence of peaks on the graphs of samples at a shift of 258 and 348cm-1 belonging to Mg2Si. Infrared spectroscopy data also indicate the presence of magnesium silicide in the films. The thickness of Mg2Si films was estimated from the data of the known dependence of the amplitude of absorption peaks at 272 cm-1 on the absorption coefficient, which gave the values of the thicknesses of the grown films. Based on the results of the study of samples in the infrared-ultraviolet range and on the basis of geometric calculations, the width of the Mg2Si band gap was determined.
