The monolithic design of the compact bandpass filter X-band is made on technology of multilayered printed circuit boards. A quarter-wave stripline resonators of the filter have two conductors divided by the layer prepreg having low parameters which is bonding together a design. This eliminates influence of prepreg on the characteristics of the devices, ensuring good repeatability of filters in mass production. For increase the high-frequency stopband of filter, one of the conductors of each resonator is cut in half by a transverse slit. The constructive sizes of the device were obtained by parametric synthesis using the electrodynamic analysis of its 3D model. The experimental data of five-order filter are in good agreement with the electromagnetic simulation of filters 3D model. An experimental device has a central frequency of the passband of 10 GHz and fractional bandwidth of 5.7%, its dimensions and weight are 18.0 × 5.4 × 2.1 mm and 0.5 g. The important advantage of the developed design is the possibility of its installation on the board using the surface mounting method.

Authors: Utkin A. V. , Fomin V. M.
Published: April 2024

In the presented work, numerical experiments were carried out in the framework of the molecular dynamics method to study the impact interaction of metallic nanoclusters of different sizes with a metallic substrate in a wide range of velocities. Analysis of the obtained data showed that the crater volume remains proportional to the impact energy and inversely proportional to the dynamic strength of the material, with the direct angle coefficient being independent of the cluster size and the cluster-substrate material.

Authors: Snopatin G. E. , Skripachev I. V. , Plotnichenko V. G. , Churbanov M. F.
Published: April 2024

Glassy chalcogenides AVBVI obtained by solidification of high-temperature melts inherit the polymolecular nature of the melt. The influence of this circumstance on the optical properties of glasses is important in connection with the use of optical fibers for fabrication and has not been adequately studied. Bulk samples of high-pure glasses As40 – xS60 + x (0 x 5) with the content of metal and silicon impurities less than 0.1‒0.2 ppm wt., carbon, oxygen, hydrogen compounds – no more than 0.5–1 ppm wt. and optical fibers from them were obtained. The IR spectra of bulk samples 12 cm long and optical fibers up to 15 m long were recorded in the spectral range 1000–2000 cm–1. Absorption bands with maxima near 1950, 1805, 1460, and 1320 cm–1, due to the content of superstoichiometric sulfur in glass, were found in the spectra of bulk samples and fibers, and the corresponding values of the extinction coefficients were determined. The results of the study allow us to consider the As2S3 stoichiometry as a factor that significantly affects the optical characteristics of glass.

The paper presents a comparative study of the characteristics of lithium iron phosphate positive electrodes with various types of commercially available carbon nanotubes – single-walled (SWCNT), double-walled (DWCNT) and multi-walled (MWCNT). Electrochemical characteristics of the cathode materials were investigated using electrochemical impedance spectroscopy and galvanostatic charge/discharge measurements. Cyclic stability at various current densities was estimated. The best electrochemical characteristics are exhibited by cathode materials with SWCNT (advantage over DWCNT at discharge rates higher than 10C) and DWCNT (advantage over SWCNT during prolonged cycling). During cycling at a current density of 1C, the greatest loss of capacity was demonstrated by the MWCNT-based electrode. At the same time, the electrodes with SWCNT and DWCNT demonstrated satisfactory capacity retention after 50 charge/discharge cycles: over 94 and over 98%, respectively.

An efficient approach to the synthesis of (+)-camphor and (–)‑fenchone anils has been developed, which consists in the interaction of the corresponding bicyclic monoterpenoid ketones with substituted anilines in the presence of the (i-PrO)2Ti(OTf)2·(i-PrOH)2 complex obtained in situ, as a homophasic catalyst, and (i‑PrO)4Ti, as a dehydrating agent. The advantage of the proposed method lies not only in obtaining target products with good yields and high purity, but also in a simplified procedure for isolating target substances, which, in turn, are of interest as pharmacologically active compounds, antioxidants for rubber compounds and components of compositions for 3D-print.

Authors: Fatykhova А. M. , Burilov V. A. , Solovieva S. E. , Antipin I. S.
Published: April 2024

By stepwise modification of gallic acid using an azide-alkyne cycloaddition reaction, a first-generation triazole-containing dendron with hydroxypropyltriazole groups and a tetraethylene glycol linker was obtained for the first time. The structure of all intermediate compounds has been proven by modern physical methods. It has been established that the use of bromomethylene derivatives of gallic acid in the synthesis of triazole-containing dendrons results in the formation of by-products of alkylation of the bases used in the reaction (triethylamine and diisopropylethylamine) due to the high mobility of the bromine atom in the benzyl position.

Authors: Fedotova T. V. , Zakharova G. V. , Chibisov A. K.
Published: April 2024

The effect of cucurbit[7,8]urils on absorption and luminescent properties of bis-thiacarbocyanine (bis-TCC) based on 3,3'-dimethylthiacarbocyanine perchlorate (TCC) has been studied in water. The existence of two forms of bis-TCC which absorb in the long-wavelength and short-wavelength regions of the spectrum has been established. The properties of the form absorbing in the long-wavelength region are similar to that of the monomer of TCC (monomeric form), whereas the form which absorbs in the short-wavelength region exhibits the properties of a non-fluorescent dimer of TCC (dimeric form). The influence of cucurbit[7,8]urils manifests itself in shifts of the band maxima in the absorption and fluorescence spectra as well as in increase in the fluorescence intensity of the monomeric and dimeric forms, and also in the presence of thermally activated delayed fluorescence of the dimeric form in deoxygenated solutions at room temperature. Results obtained from the spectral and luminescent properties indicate the ability of bis-TCC to form complexes with cucurbit[7,8]urils.

Published: April 2024

The investigations in the polycomponent high alkaline systems – TiO2–H2SO4–Na2SiO3–NaOH–H2O and TiO2–H2SO4–(NH4)2SO4–Na2SiO3–NaOH–H2O under hydrothermal synthesis conditions have been carried out to provide new products with the given technical properties. It has been shown that by directed selection of structure-forming components, in particular titanium compounds, together with optimal parameters of hydrothermal treatment of the obtained precursor, it is possible to form compounds with the given phase and chemical composition, morphology and particle size. It was found that the rate of structural transformations during synthesis depends on the phase composition of titanosilicate precursors. During their hydrothermal treatment, alkaline and thermal hydrolysis with subsequent dehydration of hydrolyzed phases of titanium (IV) and silicon take place. The process is accompanied by localization of free bonds providing formation of Ti–O–Si–O-bridges and their subsequent transformation into structured new formations.

Published: April 2024

Phase equilibria in the Li–Mn–Eu–O system were studied for the first time in the temperature range 700–1000°С, and a concentration diagram was plotted within the Li–Mn–Eu triangle at an oxygen partial pressure of 21 kPa. It is shown that the LiEuO2–Li2MnO3 system is quasi-binary, unlike the sections LiEuO2–LiMnO2 and LiEuO2–LiMn2O4. It has been established that, for spinel LiMn2O4 (Fd\(\bar {3}\)m), a homogeneous introduction of 2 mol % Eu is possible, while in the case of Li2MnO3 (C2/m), the single-phase state decays.
ON THE STRUCTURE OF THE SET OF PANCHROMATIC COLORINGS OF A RANDOM HYPERGRAPH
Authors: Tyapkin D. N. , Shabanov D. A.
Published: April 2024

The paper deals with the structure of the set of panchromatic colorings with three colors of a random hypergraph in the uniform model \(H(n,k,m)\). It is well known that the property of the existence of a panchromatic coloring with given number of colors r has the sharp threshold, i.e. there exists the threshold value \({{\hat {m}}_{r}} = {{\hat {m}}_{r}}(n)\) such that for any \(\varepsilon 0\), if \(m\;\leqslant \;(1 - \varepsilon ){{\hat {m}}_{r}}\) then the random hypergraph \(H(n,k,m)\) admits this coloring with probability tending to 1, but if \(m\; \geqslant \;(1 + \varepsilon ){{\hat {m}}_{r}}\) then, vice versa, it does not admit this coloring with probability tending to 1. We study the algorithmic threshold for the property of panchromatic coloring with three colors and prove that if the parameter m is slightly less than \({{\widehat m}_{3}}\), then the set of panchromatic 3-colorings of \(H(n,k,m)\) although it is not empty with a probability tending to 1, but at the same time it obeys the shattering effect, first described in the work of D. Achlioptas and A. Coja-Oghlan in 2008.
SEMIPRODUCTS, PRODUCTS, AND MODAL PREDICATE LOGICS: SOME EXAMPLES
Authors: Shehtman V. , Shkatov D.
Published: April 2024

We study two kinds of combined modal logics, semiproducts and products with S5, and their correlation with modal predicate logics. We obtain examples of propositional modal logics when these semiproducts or products are axiomatized in the minimal way (semiproduct- or product-matching with S5), as well as counterexamples for these properties. The fmp for (semi)products together with (semi)product-matching allow us to show decidability of corresponding 1-variable modal predicate logics.
ABOUT THE BOUNDARY CONDITION APPROXIMATION IN THE HIGHER-ORDER GRID-CHARACTERISTIC SCHEMES
Authors: Petrov I. B. , Golubev V. I. , Shevchenko A. V. , Nikitin I. S.
Published: April 2024

In this paper, we consider the problem of constructing a numerical solution to the system of equations of an acoustic medium in a fixed domain with a boundary. Physically, it corresponds to the process of the seismic wave propagation in geological media during the procedure of the seismic exploration of hydrocarbon deposits. The system of partial differential equations under consideration is hyperbolic. To construct its numerical solution, a grid-characteristic method is used on an extended spatial stencil. This approach makes it possible to construct a higher-order approximation scheme at the internal points of the computational domain. However, it requires a careful construction of the numerical solution near the boundaries. In this paper, the approach that preserves the increased approximation order up to the boundary is proposed. The verification numerical simulations were carried out.
BERNSTEIN INEQUALITY FOR RIESZ DERIVATIVE OF FRACTIONAL ORDER LESS THAN 1 OF ENTIRE FUNCTION OF EXPONENTIAL TYPE

Published: April 2024

We consider Bernstein inequality for the Riesz derivative of order \(0 \alpha 1\) of entire functions of exponential type in the uniform norm on the real line. The interpolation formula for this operator is obtained; this formula has non-equidistant nodes. By means of this formula, the sharp Bernstein inequality is obtained for all \(0 \alpha 1\), more precisely, the extremal entire function and the exact constant are written out.
DEGENERATION ESTIMATION OF A TETRAHEDRAL IN A TETRAHEDRAL PARTITION OF THE THREE-DIMENSIONAL SPACE
Authors: Kriksin Yu. A. , Tishkin V. F.
Published: April 2024

Based on the geometric characteristics of the tetrahedron, quantitative estimates of its degeneracy are proposed and their relationship with the condition number of local bases generated by the edges emerging from the same vertex is established. The concept of the tetrahedron degeneracy index is introduced in several versions and their practical equivalence to each other is established. To assess the quality of a particular tetrahedral partition, it is proposed to calculate the empirical distribution function of the degeneracy index on its tetrahedral elements. A model irregular triangulation (tetrahedralization or tetrahedral partition) of three-dimensional space is proposed, depending on the control parameter that determines the quality of its elements. The coordinates of the tetrahedra vertices of the model triangulation tetrahedrons are the sums of the corresponding coordinates of the nodes of some given regular grid and random increments to them. For various values of the control parameter, the empirical distribution function of the tetrahedron degeneration index is calculated, which is considered as a quantitative characteristic of the quality of tetrahedra in the triangulation of a three-dimensional region.

The article discusses various modifications of the nonlinear Burgers equation with small parameter and degenerate in solution of the form\(F(u,\varepsilon ) = {{u}_{t}} - {{u}_{{xx}}} + u{{u}_{x}} + \varepsilon {{u}^{2}} - f(x,t) = 0,\)            (1)where \(F:\Omega \to C([0,\pi ] \times [0,T])\), \(T 0\), \(\Omega = {{C}^{2}}([0,\pi ] \times [0,T]\,)\,\mathbb{R}\) and \(u(0,t) = u(\pi ,t) = 0\), \(u(x,0) = \varphi (x)\), \(f(x,t) \in C([0,\pi ] \times [0,T])\), \(\varphi (x) \in C[0,\pi ]\). We will be interested in the most important in applications case of a small parameter ε with oscillating initial conditions of the form \(\varphi (x) = k\sin x\), where k –some, generally speaking, constant depending on ε, and study the question of the existence of a solution in neighborhood of the trivial \((u{\kern 1pt} *,\varepsilon {\kern 1pt} *) = (0,0)\), which corresponds to \(k = k{\kern 1pt} * = 0\) and at what initial Under certain conditions on the values of k, it is possible to construct an analytical approximation of this solution for small ε.We will look for a solution in the traditional way of separation of variables on a subspace of functions of the form \(u(x,t) = v(t)u(x)\), where \(v(t) = c{{e}^{{ - t}}}\), \(u(x) \in {{\mathcal{C}}^{2}}([0,\pi ])\). In this case, the problem under consideration is degenerate at the point \((u{\kern 1pt} *,\varepsilon {\kern 1pt} *) = (0,0)\), since \({\text{Im}}F_{u}^{'}(u{\kern 1pt} *,\varepsilon {\kern 1pt} *) \ne Z = \mathcal{C}([0,\pi ] \times [0,T])\). This follows from the Sturm-Liouville theory. To achieve our goals, we apply the apparatus of p-regularity theory [6, 7, 15, 16] and show that the mapping \(F(u,\varepsilon )\) is 3-regular at the point \((u{\kern 1pt} *,\varepsilon {\kern 1pt} *) = (0,0)\), т.е. p = 3.

Wetland Plants and Aboriginal Paludiculture in North- and South-Eastern Australia
Authors: Giblett Rod
Published: April 2024

Aboriginal peoples in north- and south-eastern Australia practiced paludiculture, the cultivation of wetland plants for consumption, for many thousands of years before Europeans invaded them in the 1830s and 1840s. This article focuses on the yam daisy (Microseris spp.) in south-eastern Australia and the bulkuru sedge (Eleocharis dulcis) in north-eastern Australia in historical and recent accounts of wetlands in both regions. Aboriginal people in both places cultivated and harvested the tubers of both plants. Recent debates about Aboriginal peoples’ cultivation of native plants and whether they constitute agriculture apply the European value-laden yardstick of stages of human development with agriculture as the pinnacle of land use and constitute ‘hunting and gathering’ as lower in a hierarchy of value. They fail to appreciate not only the sophistication of the latter, but also that Aboriginal people cultivated grasses and grains on drylands (agriculture) and yams and sedges in wetlands (paludiculture).
Botanical Awareness and Adolescent Maturation in Siri Pettersen’s Odin’s Child
Authors: Bordignon Irene
Published: April 2024

This article supports the thesis that (eco)fantasy novels written for young adult people are nowadays crucial to give the next generation an ecological expertise to face environmental challenges. It is therefore important to consider what perceptions of nature are actually conveyed through the reading of these literary works, thus involving a pure dissemination of knowledge about flora. The novel Odin’s Child (Odinsbarn, 2013) by Siri Pettersen is considered here, giving voice to arboreal and botanical perspectives and basing the analysis on phytocriticism and the recent developments in ecocriticism. Odin’s Child supports the belief that a deep knowledge about botanical elements can be shared through the practice of embodiment and through an active interaction with the plant world, especially at a young age; for this reason, the importance of liminality and the role of contemporary literature in the human maturation process are underlined here. Plants play multiple sustainable roles in our life and for the survival of the planet: they are sources of medical treatments, and absorbers of carbon dioxide and other air pollutants (Jones and MacLeod 2022). Yet, it is only recently that scholars from the humanities have started analysing the role of plants in fiction, inaugurating the so-called ‘plant-turn’. The aim of this study is to highlight the importance of plants and botanical knowledge in young people’s understanding of and engagement with the natural world via young adult literature. This article’s approach will underscore the pedagogical value of ecofantasy as a suitable genre in creating empathy and a positive attunement towards flora in young readers. The central part of this paper, informed by the work of John C. Ryan (2018) and his phytocritical method, provides an analysis of the botanical elements of the econovel Odin’s Child, with an emphasis on its affective potential. A final reflection will involve new materialistic visions – such as the concepts of hybridisation (Curry 2013) and transcorporeality (Alaimo 2010) – in considering the liminal space of human/non-human and the girl/woman maturation process through which the novel develops.

Published: April 2024

In the conditions of functioning of construction enterprises, the importance of
relations between the development of a construction and investment project and its
stakeholders (stakeholders), which influence various aspects of project activities in
order to make a profit, is growing. Reducing the effectiveness of interaction between
construction developers and their partners, such as customers, contractors, design
organizations, competitors and public organizations, requires the development of
theoretical and methodological foundations for the implementation of a
stakeholder-oriented strategy for managing construction enterprises. This strategy
includes the organization of financing and implementation of a real estate development
project, ta king into account the constraints and with the aim of obtaining commercial
benefits. In today's world, construction development is a n area that is constantly
being influenced by innovative technologies and strategies. The economic development of
a country is determined by the efficiency of construction enterprises, which are an
important indicator of the status and trends of the internal and external economic
environment. The article explores innovative directions aimed at updating business
processes and organizational structures of enterprises in the field of construction
development. By analyzing and systematizing modern approaches to management and the use
of advanced technologies, the article considers such innovative areas as the
introduction of the Building Information Modeling (BIM) system, the use of intelligent
management systems, the development of digital platforms, and others. Coverage of these
areas will allow to provide an economic assessment and determine the criteria for
qualimetric and factor analysis of indicators of innovative development of enterprises
in the construction industry and their impact on the efficiency of business processes
and competitiveness of enterprises. The economic assessment of innovative development in
the development system is an important tool for enterprises seeking to achieve
sustainable growth and success. Innovations have become a key success factor in the
modern economy, especially in the field of construction and real estate development.
Ukraine, as a country with active construction activity, has a great potential for
innovative changes in this sector. However, for the effective implementation of
innovations in the activities of construction enterprises, a deep economic assessment
and economic and managerial analysis are required. This article serves as a source for
studying and understanding innovative trends in construction development and considers
the possibilities of their implementation to improve the efficiency of management and
economic diagnostics and digital administration of directive indicators for assessing
the innovative development of a construction developer enterprise.

Authors: Mazurenko Roman , Yeremenko Bohdan
Published: April 2024

The problem of traffic jams is still relevant for the transport system of many
large cities on different continents. The work is aimed at the formation of an
ontologically controlled technology, which is based on the use of available means of
data production, information resources, modelling of traffic forecasting of large cities
and traffic management based on these forecasts. That is why it pays great attention to
the research of innovative solutions to the problem of optimizing traffic through the
city network using big data, artificial intelligence models, and Internet of Things
technologies. At the same time, the main aspects that require human intervention in the
development of the reference ontology of the “Road Traffic” domain are defined. The
scientific novelty of the work arises in the creation of the ontology concept “Decision
Model”, which will later become the basis of intelligent informational technology for
effective traffic management in large cities. This development is crucial for solving
traffic congestion problems by intelligently distributing traffic flows through the city
road network, as it unifies the knowledge representation. The attention is focused on
the scheme of formation of a hybrid model of decisions, which are at various stages of
execution of the control actions of the system. The task that will be solved by the
artificial intelligence model is defined. The possibility of using the ant colony
algorithm to find the shortest path is also shown.

world of innovation. Creating value in project management is a fundamental goal for
organizations seeking to achieve their strategic goals and meet stakeholder
expectations. This article examines the concept of value creation through the lens of
consistent project management, also known as the waterfall approach. Sequential project
management is a structured methodology that divides projects into distinct phases,
emphasizing careful planning, risk mitigation, quality assurance, and clear
documentation. Creating value through consistent project management involves achieving a
balance between structured planning and adaptability. The choice of project management
methodology depends on the nature of the project and the readiness of the organization
for a structured, consistent approach. Ultimately, the pursuit of value through project
management is a continuous journey led by project professionals and organizations
committed to delivering successful projects that meet strategic goals and stakeholder
expectations.

The beginning of the full-scale invasion of russia into Ukraine caused significant
human, economic and political losses, as well as destruction of the shipping system of
water transport. Nevertheless, in the future (in the post -war period) all losses
received must be restored according to projects and programs in the post-war period.
This paper examines the current scientific and applied problem of developing approaches
to managing the success of fleet chartering projects based on proacti ve research of
shipping companies. The authors have identified the main factors affecting fleet
chartering processes: trends in the charter market; the volume of transport work in
already developed markets, opportunities to enter new markets, the level of prices for
ships, the state of the turbulent environment. The main strategic goals that determine
the need to replenish the shipping company's fleet have been established. The main types
of fleet replenishment projects corresponding to the following options for fleet
replenishment have been identified: shipbuilding, ship acquisition, leasing (bareboat
charter), short - and medium-term lease of ships (time charter). Classification of the
main types of fleet replenishment projects, regarding their classification features,
definition of products, specifics of life cycles, value and composition of stakeholders,
which fully characterizes fleet replenishment as an object of project management. As a
result of the time charter lease, the company is limited in its rights to the vessel and
can only carry out commercial activities, and this type of lease allows solving short-
and medium-term tasks related to market activity and the need to replenish the fleet.
The concept and model of the proactive formation of fleet chartering project parameters
in specific market conditions, taking into account their further development, which
ensures the establishment of project product characteristics and the life cycle, taking
into account the integral influence of the dynamics of the market conditions related to
the project. For each selected type of fleet chartering project, the main classification
features, specifics of life cycles, value and composition of participants are
established. Thus, the formation of management models for the implementation of
innovative projects, programs, in particular in Ukraine in its post-war conditions, in
the paradigm of uncertainty of crises in the post-war period, remains relevant.
A Review of the Risks of Copper Foil Manufacturing Plants. A New Facility in Catalonia, Spain
Authors: Domingo Jose L
Published: April 2024

Electrolytic copper foil (elecfoil) is a thin copper foil with a thickness less than 10 µm, which is made through electrolysis of a copper sulfate solution. It is an essential component for the manufacture of electric batteries. More specifically, it is widely used to make cathode collectors in rechargeable lithium batteries. For coming years, the expected demand of elecfoil is potentially very important. Therefore, there will be an evident need of new manufacturing plants of copper foil. In relation to this, as it can happen with any industrial facility, elecfoil manufacturing plants may pose potential environmental and health risks. These risks may affect to the surrounding ecosystems, as well as to the population living in the vicinity of the facilities. Contamination of air (particulate matter, SO2, NOx, VOCs), water (copper and other heavy metals), and soil (heavy metals and other harmful substances) is an issue of notable concern. In Mont-roig del Camp (Catalonia, Spain), a new elecfoil is currently planned. Considering the social concern that this facility –the first one in Spain- has raised in the population of the area, the current state-of-the-art on the electrolytic copper foil manufacturing plants is here reviewed. The scientific databases Scopus, PubMed and Google Scholar, as well as information obtained from different sources (Internet) were used. The available information is very scarce, if any. Anyhow, to minimize the potential negative environmental and health impacts of new elecfoil manufacturing plants, strict periodical controls, comprehensive environmental management systems, and relevant regulations are strongly required.

BACKGROUND: Quality of life (QoL(is an important factor in cancer patients through which the important consequences of disease treatment can be evaluated. This study aimed to identify QoL and its factors influencing Gastric and colorectal cancer survivors.

MATERIALS AND METHODS: A descriptive-correlation study was conducted among 120 GI cancer survivors in Tabriz city per year 2019. which was done on patients with GI cancer referred to the clinic and inpatient departments of Ghazi Hospital in Tabriz. Participants were recruited using the convenience sampling method. After obtaining the consent of the patients and data were collected by private interview method in a private environment. Data were collected using cancer-related quality of life questionnaire (QLQ-C30). The predictor factors were identified using a linear regression model.

RESULTS: The average overall QoL score was 48.98. Based on the threshold defined in the scales of physical performance, cognitive performance, emotional performance, fatigue, pain and financial problems, more than half of the patients had problems. anemia and marriage were the most predictors in all scales. HTN for global QoL scale and physical activity for symptom scale was identified as the strongest predictors. These factors predicted a significant proportion of variance for QoL, 84% for global QoL, 83.5% for functional scale, and 67.3% for symptom scale.

CONCLUSIONS: Our results indicated that the Qol of Iranian GI cancer survivors was poor. Therefore, managing some comorbidities and developing supportive care programs is essential to improve the QoL of these patients.

Published: April 2024

BACKGROUND

Malnutrition results in the most visible form of undernutrition, ultimately leading to Severe Acute Malnutrition (SAM). Globally, undernutrition is observed as a significant contributor to the global burden of disease and a leading cause of child mortality.

AIM

To assess the epidemiological determinants of SAM among children visiting Out-Patient Therapeutic Centers (OTCs) and Nutrition Rehabilitation Homes/centers (NRH) in Lumbini Province, Nepal.

METHODS

A facility-based cross-sectional study design was conducted in randomly selected OTCs and NRHs. Face-to-face interviews were conducted among mothers of children visiting the facilities using structured questionnaire, and anthropometric measurements of children were done using standardized equipment. Descriptive statistics were used to assess the socio-demographic information of the participants whereas, inferential statistics were applied to test the significance of the association between independent and dependent variables.

RESULTS

Socio-demographic characteristics showed that 53.2% participants were male, 55.8% resided in rural municipalities with two-thirds being from _Madhesi/terai _ethnic background. Children of age group 6-11 months, and 12-23 months were found to have lower odds of SAM with aORs 0.21[95% CI: (0.09-0.52)] and aORs 0.20[95% CI: (0.10-0.45)] respectively whereas mother’s age at childbirth had higher odds of SAM with aOR 2.77[95% CI: (1.33-5.77)].

CONCLUSION

The facility-based SAM prevalence of Lumbini Province was 34.9% whereby the child’s age and mother’s age at childbirth were observed as significant predictors of SAM. Implementing school and community-based training programs on behavior change communication regarding the need for proper nutrition pre and post-maternity and its outcome, could possibly be vital in reducing malnutrition as a whole.
Examining the Relationship of Chapter 1 to Other Chapters in a Dissertation or Thesis
Authors: Ngwenya Victor Chaboneka
Published: April 2024

The review examined the relationship between Chapter 1 and its subsequent Chapters in a dissertation or thesis, informed by a constructivist paradigm utilising a qualitative approach. It further demonstrated how the contrasting ontological, epistemological assumptions and models of human beings the researcher brings to the research process have direct implications for one’s methodological concerns in a project. To ascertain these philosophical assumptions, thirty postgraduate projects were purposively selected and theoretical saturation determined the sample as depth was sought employing a grounded theory.  Different Chapter 1s of various dissertations and theses were scrutinised first and used to develop a framework of analysis which was later fine-tuned using literature surveyed. Guided by an interactive process combining the elements of content and inductive thematic analysis, the major components of the study were identified, namely; the research problem, objectives, sub-problems or hypotheses. In turn, these influenced the literature surveyed, research methodology utilised, analysis and interpretation of data, conclusions drawn and recommendations made. These technicalities if carefully observed are meant to guide postgraduate students to produce a quality product independently and reveal the symbiotic relationship that exists between Chapter 1 and its subsequent Chapters in a dissertation or theses.

Burn injury patients often experience a range of psychological challenges, such as pain, anxiety, and depression. In this context, nurses have a crucial responsibility in caring for clients with mood disorders. In the current study, the authors aim to provide a comprehensive perspective on nursing role during post-burn mood disorders among burn patients by reviewing previous evidence literature. A comprehensive literature search was conducted on PubMed and Scopus databases using the following key terms "burns", "severe burns", "mood disorders", and "nursing". The search desire focused on papers related to burns, mood disorders, and nursing. 20 studies were selected for this review. Nurses play a crucial role in managing post-burn psychological conditions like depression, post-traumatic stress disorder (PTSD), and anxiety. Their responsibilities include early detection, holistic assessment, and intervention in addressing patients' emotional well-being. Educating patients and families, providing emotional support, and creating a therapeutic environment are critical aspects of nursing care. Nurses work to demystify psychological conditions, encourage mental health engagement, and implement personalized care plans. By reducing stress, promoting emotional well-being, and facilitating access to mental health services, nurses contribute significantly to burn survivors' recovery and quality of life. Nursing’s integral role in managing post-burn psychological conditions like depression, PTSD, and anxiety is crucial. Nurses provide compassionate, holistic care that meets the diverse needs of burn survivors, guiding them toward recovery.
