Post-partum iron deficiency anemia: Prevalence and impact of moringa oleifera leaves powder on hemoglobin levels in postpartum period
Authors: Gandhi Hemangini , Arora Dhwani 
Published: July 2023

Iron deficiency anemia is a cause of concern for pregnant and lactating mother globally. As per NFHS 5 Data, 52.2% pregnant women (Both Urban and Rural) are anemic in India. Iron Deficiency Anemia is associated with maternal and neonates’ mortality, restricted cognition development, low birth weight babies, Premature babies and majorly stunting which affects the nutritional status throughout the vicious cycle. Postpartum anemia is associated with an impaired quality of life, reduced cognitive abilities, emotional instability, and depression and constitutes a significant health problem in women of reproductive age. Multipronged strategies are required to curtail maternal anemia. Food based approach to prevent anemia is the most sustainable strategy. To investigate the impact of moringa oleifera leaves powder capsules on haemoglobin levels of postpartum mothers. The study was conducted in one of the govt. hospitals of Vadodara District of Gujarat, India and was a part of larger study carried on M Oleifera effects on prolactin levels. An interventional study was carried out amongst 106 postpartum mothers. Fifty-six mothers constituted the interventional group of which 45 mothers did complete compliance and 50 mothers constituted the control group of which 37 mothers did complete compliance of capsules for 30 days. Hemoglobin levels were analysed on day 0 (Baseline) and on day 7 (Endline) post-partum. Data was analysed using independent t test and appropriate statistical analysis.Findings revealed the prevalence of iron deficiency anemia to be 59%in postpartum mothers post-delivery. Mean baseline hemoglobin values for experimental and control group was 10.9 ± 1.4 g/dl and 10.3 ± 1.5 g/dl respectively on day 0 post-partum. The mean end line hemoglobin values for experimental and control group were 12.3 ± 1.5 g/dl and 11.6 ± 1.6 g/dl respectively on day 7 post-partum. The mean rise in haemoglobin levels of experimental group was 1.4g/dl and that of control group was 0.8g/dl which was significant (p=0.00001).Postpartum anemia is a cause of concern.There was a significant impact of Moringa Oleifera Leaves on hemoglobin levels of enrolled lactating mothers. Thus, it can be suggested that Moringa oleifera can be supplemented to lactating mothers’ post-partum to aid curtailing iron deficiency anemia. Improved haemoglobin levels in post-partum mothers may facilitate Exclusive Breastfeeding practices.

Published: July 2023

Research is devoted to the development of ideas about the mechanism of the flow of corrosion currents through the structures of railway tracks and buildings and the justification of methods of their protection against electrical corrosion. As a result of theoretical studies and field tests, the electric circuits of the leakage currents from the pulsating unidirectional electric potential of the POEP, which arise during the passage of the electric rolling stock along the electrified direct current railway tracks, have been clarified. Current carriers are installed in the elements and structures of the track and buildings. In concrete, soil, which are conductors of the second kind, these carriers are mainly cations Ca2+, Na+, anions OH-. It was found that in reinforced concrete sleepers, supports of passenger platforms due to the influence of POEP, zones of neutralization and leaching of concrete, cathode and anode zones of steel reinforcement are formed. Corresponding chemical and electrochemical reactions of leaching and carbonization of lime, oxidation of iron, etc. occur in these zones. It is proposed to prevent corrosion processes in these zones by diverting currents with grounded screens-coatings made of electrically conductive compositions based on mineral binders -Portland cement with a complex chemical additive or sodium silicate and a filler - dispersed graphite. The proposed indicator of the effectiveness of these screens-coatings, which is the degree of reduction of the current strength through the structure. As a result of experimental studies, it was established that it depends on the share of the contact area of the steel grounding device with the screen from the area of the screen itself, and the corresponding dependencies were obtained. New methods of protecting track structures and structures from electrical corrosion are substantiated, and appropriate structural and technological solutions are developed.
METHODOLOGICAL ASPECTS OF THE FORMATION OF QUANTITATIVE ASSESSMENTS OF SAFETY OF AUTOMATED RAIL TRANSPORT CONTROL SYSTEMS USING RISK MANAGEMENT APPROACHES
Authors: Gaievskyi Vitalii 
Published: July 2023

The article examines the issues of improving the methodology for identification and assessment of the limits of existing risks of technical operation and maintenance of automated railway transport control systems, determining and classifying the level of severity of the consequences of failures for the further selection of appropriate risk management methods that will be applied in the development of innovative control systems of railway infrastructure transport. To resolve the issue, it is proposed to consider the effects of external factors and means of the system itself, which are designed to reduce risk in order to comply with a given level of functional safety using a risk-oriented approach. The main functions of risk are defined: protective, analytical, innovative, regulatory. The risk management process is based on the results of risk identification and assessment in order to reduce the consequences of dangerous factors and threats, based on the results of which a structural block diagram of the process was built using the principle "as low as reasonably achievable" (ALARP). 9 stages of risk management are defined:
- risk assessment of potential consequences;
- decision-making regarding risk and its acceptability;
- development of measures to eliminate risks or reduce them to the lowest acceptable level;
- determination of risk probabilities and completion of the table of risk probabilities
- categories of the probability of occurrence of dangerous factors or threats;
- assessment of the severity of their consequences and completion of the risk severity table with the definition of the severity category of the consequences of dangerous factors;
- determination and classification of the level of severity of the consequences of train traffic control system failures;
- assessment of risk acceptability using the risk assessment matrix and determination of risk acceptability indices;
- risk assessment and decision-making regarding the acceptability or unacceptability of risks.
- making a decision about the need to control the assessed risk. According to the results of the study, taking into account simplifications and assumptions, it was determined that the most vulnerable elements of the control system and timely and high-quality maintenance require identification and assessment of risks. That is, using statistical data on the failure of technical equipment on the one hand and statistical data on their technical maintenance, it is possible to calculate and assess risk levels and determine and classify the level of severity of the consequences of failures and the degree of their acceptability using quantitative and qualitative methods. The obtained results will be applied to the selection of appropriate risk management methods and further improvement of automated management systems by expanding their capabilities and providing them with additional functions.

Juniperus deltoides is a relict species from the Tertiary Period. It is a typical representative of the Mediterranean group of the section Juniperus. It is included in the Red Books of the Republic of Crimea and the city of Sevastopol. Until recently, it was believed that a population of J. oxycedrus grew in Crimea. Currently, J. deltoides is described as a cryptic species, morphologically difficult to distinguish from J. oxycedrus. As a result, it became necessary to conduct a series of detailed studies to determine the morphological and phylogenetic features of the Crimean cryptic population in order to identify it as being one of the species of the cryptic pair. The studies were carried out in two stages: at the first stage, the morphological features of the vegetative and generative organs and their difference from J. oxycedrus were determined; the second stage included genetic research. The length of the needles of the Crimean population is 12.94 ± 0.19 mm, which corresponds to the Eastern Italian population of J. deltoides. At the same time, the width of the needles is 1.39 ± 0.02 mm, which is typical of the Portuguese population of J. oxycedrus. The dimensions of the cones are d1 (conditional height) = 7.54 ± 0.14 mm, and d2 (conditional width) = 9.11 ± 0.09 mm, which is more in line with J. deltoides. The shapes of the cones are very diverse. Some individuals have cones, the covering scales of which are visually indistinguishable, and their tops are completely fused. A similar phenomenon is characteristic of the Western Mediterranean populations of J. oxycedrus. Morphological analysis of the vegetative and generative organs of J. deltoides showed that when these two traits are combined, it is not possible to reliably distinguish between J. deltoides and J. oxycedrus individuals. Nuclear (ITS internal transcribed spacer) and chloroplast (petN-psbM, trnS-trnG) non-coding regions of the genome were used for genetic analysis. Studies have shown that the nuclear regions of genes have greater variability than chloroplast regions. The sequences obtained in this work formed a clade with J. deltoides samples 9430 and 9431 (BAYLU) growing in Turkey, which makes it possible to assign the samples studied to J. deltoides.

Authors: Becker Fernando 
Published: July 2023

Apresenta-se parte da pesquisa Epistemologia Subjacente ao Trabalho Docente, com dados coletados no Peru, Chile e Uruguai, mediante entrevistas a 17 docentes, do primeiro ao terceiro grau de ensino. Ela visa a identificar concepções epistemológicas que fundamentam o ensino de Matemática e verificar se tais concepções assemelham-se às encontradas no Brasil. O objetivo desta análise é apreender as concepções epistemológicas subjacentes às respostas às questões 20-23 da pesquisa. Os docentes supervalorizam a matemática que ensinam e pensam que os estudantes a subestimam. O resultado é a quase total ausência da compreensão de que os conhecimentos matemáticos resultam de processos construtivos. Atribuem as aprendizagens ao ensino (empirismo), sem tematizar a origem de tais capacidades ou estruturas (apriorismo); acreditam amplamente em sua realização pela memorização de algoritmos, pondo em segundo plano processos criativos e inventivos como a resolução de problemas. A referência teórica básica é a Epistemologia Genética piagetiana.

E-module is considered as an effective learning media to create an interactive learning environment. In spite of that it is rare to find the research that examines the development of e-module based on Problem-Based Learning model that integrates Socio-Scientific Issues on argumentation skills to students. This research aims to develop students’ argumentation skills through problem-based e-module with socio-scientific issues topics. The researcher used pre-experimental method with one-group-pretest-posttest design. The e-module was implemented to 36 students of Biology Education, State University of Malang, for the 2nd-year from November to December 2022. The research sample was selected by non-random sampling. The research samples were selected by non-random sampling. The research data were collected by opened-ended questions to assess the students’ argumentation skills and categorized based on the argumentation skills rubric. The data were analyzed based on the increase of pre-test and post-test scores by using Normalized Gain (N-Gain). The result of the N-Gain calculation showed a score of 0.46 which means the students’ argumentation skills developed in the moderate category after the implementation of using problem-based e-module with socio-scientific issues topics. The problem-based e-module with socio-scientific issues topics can train students to identify the problems, analyze data and evidence to give problem-solving solutions packaged of complex argumentation.

The subject of the research is the most common type of detachable joints in chemical, petrochemical, oil refining, food and energy machine and apparatus construction, namely flanged joints of technological and auxiliary equipment, as well as pipelines.
The study of the state of the issue and trends in the development of structural and technological design of flanged joints is based on a critical analysis of scientific and technical sources of information and, above all, patent information of the leading countries of the world, since it is in the patent documentation that information is given about innovative developments in the relevant field of engineering and technology.
With the help of methods of analysis and synthesis, flange connections that affect the efficiency of operation of equipment and pipelines in the chemical and related fields of technology have been systematized. A thorough classification has been developed for each type of device, based on which the most interesting designs proposed by scientists, designers and inventors of the world's leading countries have been examined in detail. A critical assessment of most of the above constructions is provided, their advantages and disadvantages are discussed. Preference is given to sources of information from the end of the second and beginning of the third millennium.
The constructions of flanged joints were analyzed depending on the degree of assembly, the degree of mobility of their structural elements, the possibility of removing the flanges without dismantling the entire joint, the mechanism of compression of the sealing gasket, the presence of additional functions, as well as the material of the flanges.
It is shown that, despite the considerable variety of developed designs of flanged connections, the most demanded by the industry are flat welded and butt-welded flanges, as well as free flanges on a welded ring. However, thanks to the advances in materials science and computer modelling, the search for new flange connection designs continues.
The developed detailed classification of flange connections can be useful to the developers of new equipment for the creation of highly efficient technological equipment of various industries.
Electrochemical Investigations of <em>Aloysia citrodora</em> Paláu L. Water Extract for Iron-Chelation Abilities in Alzheimer’s Disease

Published: July 2023

Alzheimer’s disease (AD) is the leading cause of dementia, characterised by beta-amyloid plaques, neurofibrillary tangles, and oxidative stress. Iron is suspected to enhance disease progression, and chelation may be a potential treatment. We propose that Aloysia citrodora Paláu (AC), a plant in the Verbenaceae family, can act as a moderate chelator of iron. It may reduce the effect of iron on beta-amyloid 1-42 (Aβ1-42) aggregation. Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) were used to demonstrate that AC can interact with iron (II) and iron (III), the two most abundant forms of iron within the body. DPV was also used to characterise Aβ1-42 aggregation, and two main features were obtained. The first is the tyrosine peak (~0.6 V) decreased in magnitude over time, which is a sign of aggregation and folding. The other is a conglomerate of peaks at ~0 V, whose identity is unknown. Furthermore, iron (II) increased the rate of tyrosine peak depreciation, and the addition of AC negated this induced effect. This implied that iron (II) increases Aβ1-42 aggregation into higher order, and AC may be an effective countermeasure.
