Fostering Literacy Culture: An In-depth Exploration of the Reading Corner Initiative at Madrasah Ibtidaiyah Nyatnyono 01 Semarang Regency
Authors: Cahyaningsih Esty , Khoiruddin Nasution
Published: February 2024

This study delves into the enhancement of literacy culture at Madrasah Ibtidaiyah Nyatnyono 01, Semarang Regency, through Talcott Parsons' functional-structural theory, particularly the AGIL framework (Adaptation, Goal Attainment, Integration, and Latency), using a qualitative case study method. Structured interviews with key personnel like Mrs. AL, the head of the Madrasah, participatory observation, and documentation analysis formed the basis of data collection, which was analyzed through the Miles and Huberman model for structured and reliable insights. The research facilitated by the Reading Corner initiative highlights significant improvements in literacy among students. Adaptation was evident as students actively engaged in reading activities during breaks, while Goal Attainment was reflected in integrating literacy into various subjects, aiming for improved academic performance. Integration was achieved by blending literacy with diverse issues using innovative teaching models and motivational materials, and Latency was seen in the internalization of literacy habits within the school community. Despite its specific focus and the need for further research to explore long-term impacts in varied contexts, this study contributes to the broader discourse on literacy, emphasizing the need for culturally specific approaches in educational settings and providing a potential model for enhancing literacy culture in other institutions.
Exploring the Concept of Peace in Islamic Teachings: A Comprehensive Analysis of Surah Al-Anfal Ayat 61
Authors: Nasywa Hilmi
Published: February 2024

This research explores the conceptualization of peace in Islamic teachings, focusing on Surah Al-Anfal Verse 61 in the Quran. The method employed in this study is a literature review. The data collected and analyzed are secondary research findings from books, journals, articles, websites, and other relevant sources. Furthermore, the data analysis technique used in this research involves content analysis. The research findings reveal a comprehensive discussion of the relationship between Islam and the principles of peace. Verses in the Quran, particularly Surah Al-Anfal Verse 61, guide believers to lean towards peace and trust Allah when faced with the desire for peace. The Quran portrays Islam as a religion of peace, where peace is the general rule, and war is only justified in specific, compelling circumstances. The fundamental goal of Islam is to transform human thinking, initiating an intellectual revolution based on the oneness of God or Tawhid. The implications of this research extend beyond the academic realm, influencing broader discourse on Islam and peace. The proactive roles of Islamic organizations such as NU and Muhammadiyah in regional and international peace initiatives demonstrate the practical application of Islamic values. This research provides recommendations for universities to actively promote peace in contemporary society by emphasizing the crucial values of peace and security in human existence, as outlined in Surah Al-Anfal Verse 61.

Published: February 2024

The Persian walnut (Juglans regia L.) is one of the most lucrative and widely distributed nut crops. It is appreciated as a forestry and ornamental tree in addition to its benefits as a fruit crop. Although Central Asian countries, especially Uzbekistan, are among the origins of the Persian walnut; they are not considered as top industrial producers of walnuts. Uzbekistan possesses a wide range of walnut genetic resources and as a result of conducted research, several promising, fruitful, early-harvesting varieties and forms have been selected. The aim of this study is to optimize microclonal in vitro propagation of selected Uzbekistan local varieties and forms by evaluating concentrations of different plant growth regulators and genotype on multiplication and rooting stages. As mother plants, 2 forms and one variety were selected: the Ideal variety, 'Form PDM23' and 'Form 202YaKT'. ?n the proliferation stage, the growth rate of walnut microshoots on basal medium Driver and Kuniyuki Walnut Medium (DKW) with different concentrations of 6-benzylaminopurine (BAP) and Indole-3-butyric acid (IBA) (0.01 mg/L) was studied. The rooting stage was assessed in half strength macronutrient DKW medium containing different IBA concentrations (0.0, 2.0, 4.0 and 6.0 mg/L). The Ideal variety and 'Form PDM23' performed best in DKW medium supplied with 1.5 mg/L BAP and 0.01 mg/L IBA, whereas 'Form 202YaKT' performed best in DKW medium supplemented with 1.0 mg/L BAP and 0.01 mg/ L IBA for the proliferation stage. For all genotypes, 6.0 mg/L IBA provided the best rooting results.

Authors: Maroyi Alfred
Published: February 2024

In the current investigation, an attempt has been made to document the floristic diversity and chorotype analysis of Pteridophytes growing in Zimbabwe. Previously published literature and online sources were consulted to confirm the nomenclature, precise locations, chorotype, stages of invasion, and conservation status of the Pteridophytes in Zimbabwe. The updated list of Pteridophyte taxa confirms that there are 297 taxa belonging to 83 genera and 19 families. The largest family is Aspleniaceae, with 78 taxa (26.26%), followed by Polypodiaceae and Pteridaceace with 67 taxa (22.56%) and 54 taxa (18.18%), respectively. The largest genus is Asplenium L., with 46 taxa (15.49%), followed by Hemionitis L. with 22 taxa (7.41%), Ophioglossum L. (16 taxa, 5.39%), Thelypteris Schmidel (14 taxa, 4.71%), and Elaphoglossum Schott ex J.Sm. (12 taxa, 4.04%). A total of 20 taxa (6.73%) are threatened with extinction, emphasizing the need for detailed knowledge of the nomenclature, conservation status, and distribution of Pteridophytes taxa in Zimbabwe. Research focusing on the diversity, ecology, and conservation status of Pteridophytes is imperative for biodiversity conservation, as they are an important component of natural ecosystems adapted to different habitats. Therefore, future studies on Pteridophytes in Zimbabwe should explore how the lack of floristic data on the plant group can hinder ecological research.

Authors: Shi Yuhui , Zheng Yi
Published: February 2024

To increase the specific surface area of corn starch and remove the anion contaminant in water, STP-OGG-DD, which is composed of porous corn starch (Stp), methylpropenoxyethyl trimethyl ammonium chloride (DMC) and dimethyldiallyl ammonium chloride (DMDAAC), was prepared and used for the flocculation of humic acid (HA). In this preparation, ferrous sulfate and hydrogen peroxide act as initiators for free radicals that attract cationic monomers to gather on starch chains. The effects of reaction time, reaction temperature, dosage of cationic monomer, and initiator on the reaction performance were investigated. The results showed that the conversion rate of starch monomer was 97.69 %, the grafting rate was 96.47 %, and the grafting efficiency was 95.85 %. Stp-OG-DD was characterized by scanning electron microscopy, and its structure was characterized by X-ray diffraction and infrared spectroscopy. In the flocculation test. The flocculation effect of 30 mg/L flocculants with different grafting rates on 30 mg/L humic acid was investigated, and the relationship between the two was studied. The results showed that the flocculant with a high starch grafting rate had a better removal effect on humic acid and was positively correlated. Different from the traditional gelatinization method, the enzymatic hydrolysis method is used to pretreat starch, which not only saves energy but also enlarges the specific surface area of molecules. In addition, adding two cationic monomers improved the grafting effect of starch. DMC and DMDAAC could be polymerized alternately onto the starch backbone, providing long molecular chains and abundant positive charge for enzymatic hydrolysis of starch molecular chains. In addition to exploring the grafting of samples under reaction conditions, flocculants prepared under different conditions were used to flocculate 30 mg/L humic acid to further determine the role of grafting rate in the removal effect.
The Draft International Covenant on the Right to Development and Its Implications for Cooperation in Global Health Crises
Authors: Wissmann Sara Katharina
Published: February 2024

During the COVID-19 pandemic, global cooperation arrived at an impasse, illustrated by the resistance of industrialized States to allow vaccines-related knowledge transfer to their economically less advantaged partners. One pertinent example is the EU, withholding its waiver of the TRIPS Agreement for vaccines and related medicines and thereby impeding knowledge transfer to States in need – an act that has also been referred to as ‘vaccine apartheid’. In the meantime, a new legal instrument intending to address in broader terms the faltering international cooperation emerged on the horizon: the Draft International Covenant on the Right to Development (DICRTD). Concerning health, the DICRTD’s preamble already recalls Arts. 1 (3), 55, and 56 UN Charter to take joint and separate action in cooperation with the UN to promote solutions of, inter alia, health problems. Reflecting on lessons learned from the COVID-19 pandemic, the preamble also points out health emergencies and health crises as serious obstacles to the realization of the right to development. This contribution seeks to critically assess the potential of the future DICRTD to address global health crises through cooperation. Against this backdrop, it analyses the current legal status of the duty to cooperate, the potential transformative impact of the DICRTD on this legal status, and the effectiveness of the DICRTD’s implementation mechanism.

Published: February 2024

Drought is a major problem worldwide for agriculture, horticulture, and forestry. In many cases, major physiological and biochemical changes occur due to drought stress. The plant’s response to drought stress includes a set of systems for intracellular regulation of gene expression and inter-tissue and inter-organ signaling, which ultimately leads to increased stress tolerance. Meanwhile, the role of plant growth-promoting bacteria in improving many harmful consequences of drought stress has been discussed. One of the new ways to increase tolerance to drought stress in plants is drug design using methods based on computer analysis, bioinformatics, pharmacokinetics, and molecular docking. The present study aimed to identify volatile and non-volatile compounds involved in drought tolerance using molecular docking methods. In this research, among the volatile and non-volatile compounds effective in increasing growth and inducing drought tolerance, compounds that have a high affinity for interacting with the active site of late embryogenesis abundant (LEA) protein were identified through molecular docking methods, and it was presented as a suitable inhibitor for this protein. Based on the docking results, the inhibition potentials of the studied compounds differed, and the most vital interaction in the case of LEA 3 protein was related to the gibberellic acid compound, whose energy is equivalent to −7.78 kcal/mol. Due to the basic understanding of many mechanisms operating in the interactions of plants and bacteria, it is expected that the practical use of these compounds will grow significantly in the coming years, relying on pharmacokinetic methods and molecular docking.

Published: February 2024

The analysis of the fluid flow with the energy transfer across a stretching sheet has several applications in manufacturing developments such as wire drawing, hot rolling, metal extrusion, continuous casting, paper production, and glass fiber fabrication. The current examination presents the hybrid nanofluid flow past a convectively heated permeable sheet. The ferrous oxide (Fe3O4) and Gold (Au) nanoparticles have been dispersed in the blood. The significances of thermal radiation, inclined magnetic field, and space-dependent heat source have been observed in this work. The modeled equations are presented in the form of partial differential equations and reformed into the set of ordinary differential equations (ODEs) by using the similarity substitution. The Matlab built-in package (bvp4c) is employed to resolve the transform nonlinear set of ODEs. The significance of flow constraints versus the velocity and temperature profiles is demonstrated in the form of Figures and Tables. The numerical outcomes for the physical interest quantities are presented in tables. It has been perceived from the results that raising the angle of inclination from 0° to 90° reduces both the velocity and energy profile. The escalating values of Eckert number, constant heat source, and space-dependent heat source factor accelerate the temperature profile. The velocity and temperature distributions are very effective in the cases of hybrid nanofluid (Au–Fe3O4/blood) when compared to nanofluid (Au/blood). The skin friction and rate of heat transfer are very effective in the cases of hybrid nanofluid (Au–Fe3O4/blood) when compared to nanofluid (Au/blood).

Published: February 2024

Antimicrobial resistance (AMR) as one of the world’s most pressing public health problems needs immediate attention, because it has the ability to affect the human healthcare, agriculture, and veterinary industries. Despite warnings about overuse and their implications, antimicrobials are overprescribed worldwide for humans and animals, which leads to the promotion of resistant microorganisms such as bacteria. Food is a medium for exposure to or transfer of residues of the drugs and can contribute to the burden of the pharmaceuticals associated with development of AMR. Studying on residues of veterinary drugs in foods is essential in the fight against AMR. Herein, we introduce a new method for visualizing the residues of a veterinary drug in animal matrices using radionuclides, called “Depletion Imaging”. Amoxicillin was chosen to be the first antimicrobial for this study. The drug was labeled with [62Zn/65Zn] ZnCl2. Radiolabelled amoxicillin and non-labeled amoxicillin were administrated to rainbow trout fish simultaneously. To enable visualization of the remaining residues of amoxicillin in fish, In-vivo positron emission tomography (PET) imaging was done at different intervals from 30 min to 21 days after administration. Evaluation of the amount of radiolabelled amoxicillin in fish was done using a high purity germanium (HPGe) nuclear detector, and enzyme linked immunosorbent assay (ELISA) technique was used for the non-labeled drug. In this study, a comprehensive method for in-house production of zinc radioisotopes was also included. The results showed that depletion imaging and biodistribution study based on gamma spectroscopy of radionuclides in tissues, is a precise method for accurate understanding of the drug’s distribution, metabolic and excretory profile.
What Does It Mean to Be “Utterly Content”? Semantic Prosody Impacts Nuanced Inferences Beyond Just Valence
Authors: Hauser David J. , Hillman James
Published: February 2024

Words have semantic prosody when they collocate with positive/negative concepts in natural language. Semantic prosody encourages positive/negative evaluations. However, it is unknown whether semantic prosody affects inferences of other attributes aside from positivity/negativity. Semantic prosody likely causes people to expect the valence of what comes next, and expectation violations occur when authors have ironic intent and when authors lack fluency with a language. Four studies investigated whether semantically prosodic expectations impact specific inferences about authors. Participants perceived a writer as having greater ironic intent when the writer used a sentence with a semantically prosodic word that mismatched with the valence of adjacent words (Studies 1, 3, and 4). Additionally, in line with English as foreign language pedagogy, the same manipulation caused participants to perceive a writer as being less fluent in English (Studies 2, 3, and 4). Thus, semantic prosody generates expectations that affect nuanced inferences.

Purpose – The purpose of the speech is to present the results of empirical verification of the occurrence of the political cycle in the property expenditures of cities with county rights. The timeliness of the topic and research objective undertaken is current challenges for local finance management under conditions of uncertainty, the results of national and international research to date, as well as the risks associated with various types of risk, including political risk. Research method – The realization of the objective will be based on the presentation of the most important issues of the subject literature and quantitative methods. For quantitative research, panel data analysis was used. In order to detect the existence of signs of the existence of a political cycle, a trend model of property expenditures with fixed effects was estimated (it was assumed a priori that units differ from each other). The source of the data is the budget reports published by the Ministry of Finance on the website of the Public Information Bulletin. Results – The results show that there is a political budget cycle in investment expenditures, which is strongly determined by the timing of local elections. Observations confirm that investment expenditures are strongly determined by the timing of local elections. The survey also showed an autocorrelation of property expenditures, which may indicate that the investments implemented by cities may be multi-year in nature. Originality / value / implications / recommendations – The conducted analysis may be a stimulus for further research related to the effects of the political cycle and an attempt to identify the remaining political risk factors.

Published: February 2024

Purpose – Assessing the level of and differences in own revenue potential of small cities having the status of urban municipalities. The study intended to answer the following research question: do the cities having the status of urban municipalities lag far behind greater towns in terms of own revenue potential, and has the gap between them grown over the years? – Is there a wide diversity in the level of own revenue potential of small towns depending on their level of development and functions? – What are the most important internal determinants affecting the level of own revenue potential of small towns with urban municipality status? Research method – The empirical research was conducted based on secondary data from the Local Data Bank of Statistics Poland, processed using basic descriptive statistics and taxonomic methods. The focus of the study was on small towns (with less than 20 thousand inhabitants) with urban municipality status (116 entities in 2020). The time span of the study was 2007–2020. Results – The potential for own revenue of cities having the status of urban municipalities varies strongly between them, but is on average only slightly smaller than that of other urban municipalities. Also, the fact that it is growing should be viewed as a positive development. While its level is impacted by internal conditions, external ones were the reason why in 2020 it stopped growing as fast as in the previous years. Originality / value / implications / recommendations – Monitoring the level of small cities’ own revenue potential due to their importance (77% of all cities, “rural growth poles”, “local development centres”) is aimed, among other things, at identifying financially disadvantaged units that may require state intervention in accordance with the implementation of the subsidiarity principle.

Purpose – The aim of this article is to assess the impact of environmental taxes in terms of sustainable consumption and production. Examination of the correlation between environmental tax revenues in the European Union countries and sustainable consumption and production indicators will allow us to make this assessment. Research method – The study used the method of literature analysis and comparative analysis using structure, dynamics, correlation, median and arithmetic mean indicators. The numerical data for the research were obtained from the Eurostat database. Goal no 12 performance indicators were used as a variable to measure the impact of environmental taxes in each Member State. Results – The results of the correlation analysis conducted clearly indicate that in the case of the indicators: energy productivity, average CO2 emissions of new passenger cars per 1 km, consumption of materials in a closed loop, and the gross value of goods in the sector of environmental goods and services, significant relationships were obtained in a large group of EU countries in the desired directions. The hypothesis has been positively verified. Originality / value / implications / recommendations – It is very important from the point of view of sustainable development, and especially sustainable consumption, to define the role of tax fiscal instruments. As an important instrument of public finance, they should support the implementation of sustainable development goals. As a result of the conducted analyses, an attempt will be made to formulate recommendations in terms of the functioning of tax fiscal instruments for sustainable development.

Published: February 2024

Purpose – Determine the level of social and economic convergence of the various countries of the European Union and its changes over time by creating rankings of countries. Research method – A synthetic measure of development was created using various normalization methods. In addition, the quality of the classification carried out was checked, using Kendall’s rank concordance coefficient, which made it possible to examine whether there is a process of gamma convergence between the countries of the European Union. The study was carried out for selected 8 years from the period 2000–2022, which made it possible to assess changes over time. Results – The occurrence of statistically significant gamma convergence in the group of countries studied was confirmed throughout the period under review. In 2009, the convergence process was weakened due to the economic collapse caused by the global economic crisis, and in 2016 it was weakened by the occurrence of the banking crisis in Europe and the onset of reflation after a period of falling prices in the economy. The outbreak of armed conflict in Ukraine in 2022, also indicates a negative impact on the gamma convergence process. It should be noted that Brexit did not have a significant impact on the convergence process in the group of countries studied. Originality / value / implications / recommendations – Constructing a synthetic measure of social and economic development makes it possible to rank countries according to accepted measures that meet the conditions of universality, variability, validity and stability.
Crowdfunding as a form of financing sports projects. Example of football
Authors:   University of Wrocław, Ziobrowska-Sztuczka Justyna
Published: February 2024

Purpose – The goal of this article is to identify the possibilities of using crowdfunding in sports using football as an example. Research methodology – The article is theoretical and empirical in nature. The first part discusses the definition and process of organising crowdfunding collections and analyses selected successful crowdfunding campaigns involving local football sports club communities. A literature analysis and case study method were used and a SWOT analysis was conducted as a conclusion. The second part of the article complements the theoretical considerations in the form of a research report conducted among a group of football fans in Poland, in which their position towards crowdfunding is discussed. A diagnostic survey method was used for this purpose and a statistical analysis was carried out. The following research hypothesis was adopted: The use of crowdfunding as an alternative funding method can positively influence the development and support of football clubs, especially those in the lower leagues, by increasing the availability of funds and community involvement. The use of crowdfunding as an alternative funding method influences the development and support of football clubs by increasing the availability of funds and community engagement. Results – Based on the results of the study and the analysis of the literature, it was concluded that crowdfunding can be an effective tool to raise funds for football, but requires proper planning, community involvement, and effective communication. A good definition and understanding of the project’s goals and increased education of the fan community in crowdfunding will help convince them to support it financially. Football fans who support their favourite club financially consider crowdfunding a more effective funding method than fans who do not financially support their favourite club. In addition, we found that football fans financially supporting and not financially supporting their favourite club had a similar opinion regarding the impact of crowdfunding support on the development of small football clubs, and were similarly keen to crowdfund football projects. Originality / value / implications / recommendations – The article deals with the use of crowdfunding in football, which makes the paper original, as this sphere is still poorly covered in the literature.

This paper presents a general analysis from the geosciences of structural collapses. The analysis was conducted in the crop fields of Santa María Zacatepec, in the city of Juan C. Bonilla, Mexico. The analysis implemented the Remote Sensing technique, facilitating the interpretation of band combinations and determining the geometry, geology, geomorphology and cartography of the site under study. A summary analysis of the work performed is presented, in addition to showing simulation models of the hydrological outflow and water acceleration in the runoff structural slopes, data that were used for the final mapping and graphic modeling. A geomorphological, geological, and topographical study of the site was conducted, using satellite and aerial telemetric techniques. Specialized software was also used for geodetic surveys, mapping in 2D and 3D models of the analysis area. Surveys of the site were carried out to determine the shape of the structure and identify potentially risk areas for the population near the collapse events. Orthophotos were obtained to calculate and determine the slope by distance-elevation, acceleration-height, water flow and force, which served to conclude the possible causes that led to the collapses and have sufficient technical data that were shared with the civil protection authorities.
Bank resolution and national insolvency law: the case of group financing
Authors: Haentjens Matthias , Kokorin Ilya
Published: February 2024

This article explores the complex interplay between bank resolution and national insolvency law, with a specific focus on intra-group financing. We discuss group financial support agreements under BRRD, prudential requirements under the CRR, iMREL under BRRD, and harmonisation of national bank insolvency laws. We conclude that without harmonisation, the dependence of bank resolution on national insolvency laws continues to result in legal diversity and uncertainty, and thus may jeopardise effective resolution.

Factors Affecting the Absorption Term in the Size Press Equation
Authors:   Reed Engineering & Development Services Ltd,. Maidstone, Kent, Wilson C. M. W.
Published: February 2024

The equation for pick-up of surface sizes on the size press recently proposed by Hoyland & Howarth contains three terms. These are the immobilisation term and the absorption term, which are controlled by the sheet and the hydrodynamic term, which is primarily a function of speed. This paper describes pilot plant experiments to establish how the immobilisation and absorption terms are related to the various aspects of the sheet structure and composition . The most important factors were found to be structural differences associated with freeness changes and the presence of very small quantities of resin size. The latter were important at levels well below those associated with normal size addition.

Print quality criteria are classified and listed from the point of view of paper printability. The theoretical background of such important print quality characteristics as print density and gloss, evenness, contrast and sharpness are presented. The effects of the components of ink transfer-coverage, immobilisation and splitting-on the resulting ink film structure are discussed. The connection between roughness distribution of paper and coverage in ink transfer are examined and an improvement is proposed for the previous coverage theory of Hsu. The use of laboratory test printing and full-scale pressruns are recommended for printability evaluation of paper and the methods used in determining various print quality numbers are reviewed.
The Softness of Household Paper Products and Related Products
Authors:   Swedish Forest Products Research Laboratory, Stockholm, Hollmark B. H.
Published: February 2024

The results of psycho-physical scaling experiments have shown that a property such as softness can easily be scaled like other subjective variables such as loudness and brightness. They have also shown that bulk softness and surface softness should be treated separately. In search for physical measurements correlating with the subjective properties, one has to proceed along slightly different pathways. For bulk softness, a known physical property-bending stiffness (or, more correctly, inverse bending stiffness)- has been chosen as a good substitute for subjective bulk softness. An instrument using a ‘synthetic fingertip’ has been developed for measuring surface softness. The basic principles of the system, as well as recent experimental results are reported.

Published: February 2024

The thermal stability of papermaking pulps under conditions of accelerated ageing was examined. Degradation was found to be extremely complex and influenced both by the technical processes of papermaking and by the experimental methods used. At moderate temperatures as used for accelerated ageing, the folding endurance test was a sensitive measure of degradation. Methods of reducing the variability of the test were considered and a new technique capable of handling widely different results was developed and evaluated. Several papermaking pulps were artificially aged and the resultant loss of strength attributed to the interaction between a gradual fibre strength reduction and a rapid increase in interfibre bonding. Excessive initial interfibre bonding decreased handsheet stability. Softwood sulphite and kraft pulps were more stable than a birch kraft pulp, but the behaviour of sulphite pulps varied greatly. The presence of lignin or of high hemicellulose content was not of itself sufficient to cause rapid ageing.

Fibre fractionation in the Hydrodynamic Fractionation Device (HDF) was studied for changing suspension flow parameters, i.e. different channel Reynolds numbers Re and accept flow rates up to 20% of the feed flow rate. The suspension flow behaviour was described using images recorded with a high-speed camera system. Fractionation performance was determined based on mass balances for a variety of length fractions of the pulp. Low Reynolds number flow characterised by Re = 1300 led to the formation of a fluid gap between the wall and the fibres located at the channel centre. Best fractionation performance was achieved for flow at this Reynolds number: no fiber removal was observed at 10% accept flow rate, and only 1% of the fibres were removed at 20% accept flow rate. A design space was established that highlights the optimum settings for fractionation in an HDF, which at low Re and high accept flow rate. Surprisingly, we found a significant increase of fines mass flow rate in the accept upon an increase of the Reynolds number. We speculate that a flow regime-dependent interaction of fines with the fibres exists in the HDF that critically affects the amount of fines in the fluid gap near the wall.

Anastomotic leak and anastomotic fistula after esophagectomy are frequent and detrimental complications after esophagectomy. Endoluminal vacuum therapy has been used as alternative treatment for these type of complications refractory to use of lumen-apposing metal stents and other endoscopic modalities. In this report, we describe successful endoscopic closure of anastomotic leak and anastomotic fistula with fibrin sealant as adjuvant therapy after vacuum therapy failed to completely treat these complications.

The article proposes that human rights educators not only focus on considering the human rights violations that were committed in Latin America during dictatorships and authoritarian regimes, but also those that are perpetrated on a daily basis, in everyday life, in daily life in a series of times and places. The examples of these violations are multiple and take place in diverse areas; work, homes, schools etc. Different attitudes and behaviors are related and cause violations of human rights in everyday life: threats, violence, discrimination, poverty. etc The article concludes by listing some pedagogical principles to address human rights violations in everyday life: participation, dialogue, criticality, etc.1
Ultrasound-Assisted Lumbar Punctures in Children: An Updated Systematic Review With Meta-Analysis
Authors: Ćwiek Agata , Kołodziej Maciej
Published: February 2024

CONTEXT

Lumbar puncture (LP) is a common procedure in children, but the rates of unsuccessful and traumatic LPs remain high. Point-of-care ultrasound (POCUS) has been proposed as a tool for improvement.

OBJECTIVES

Our aim was to systematically review current evidence on the usefulness of POCUS assisted LP in children.

DATA SOURCES

PubMed, Embase, and the CENTRAL were searched up to November 2022.

STUDY SELECTION

We searched for randomized control trials assessing the effectiveness of POCUS assisted LP in children.

DATA EXTRACTION

Data were extracted by 2 reviewers independently.

RESULTS

Seven randomized control trials involving 618 participants were included. Overall, the first attempt POCUS assisted LP was successful in 72% compared with 59.6% in the standard group, regardless of the definition used. The calculated risk difference was 13.0% (95% confidence interval [CI]: 3% to 23%) I2:53%, odds ratio: 2.00 (95% CI: 1.13 to 3.53), I2: 45% and risk ratio:1.21 (95% CI: 1.01 to 1.44) I2:64%. Additionally, fewer traumatic LPs occurred in the US-assisted group, with a risk difference of −12% (95% CI: −0.22 to −0.03), odds ratio: 0.45 (95% CI: 0.26 to 0.78) and risk ratio: 0.53 (95% CI: 0.35 to 0.79). POCUS did not extend the duration of LP procedure with mean difference: −1.11 (95% CI: −2.88 to 0.66).

CONCLUSIONS

POCUS improved the first attempt success rate and reduced the incidence of traumatic LPs compared with standard LP procedure in children. Therefore, if it is available, POCUS should be used routinely before every LP, especially when performed by less experienced physicians.

Take into account additive manufacturing while design lattice implant can improve load-bearing properties and decrease construction weight. The usage of lattice structure and biomaterials makes it possible to solve the main problem of arthroplasty – preservation of the implant after surgery in the patient's body. Unfortunately, nowadays biomaterials do not have the necessary strength capacity. In spite of this, a lot of researches are directed towards to develop new design methods or improve the existing ones. There are number of articles focused on in-situ testing and quality control of lattice structures. The study is devoted to investigate the buckling of lattice structures under uniaxial compression with synchronous X-ray computed tomography scanning. In the article an experimental study of lattice structures of two kinds has been carried out. Edges of hexagonal bipyramid were a basic cell of the samples. The distribution of basic cells in the first type of construction was uniform, and was non-uniform in the second type. The studied samples were manufactured by laser stereolithography method. The lattice structures were loaded step-by-step with a longitudinal compressive load. The loading of the specimens was carried out in cooperation with their scanning by X-ray computed tomography. As a result, the displacement fields of structures at each step of loading were obtained. The general and local buckling of lattice structures was revealed. The general buckling occurred at the second loading step for each type of structure. Local buckling was observed at the third loading step. The influence of the architecture of the lattice structures on the buckling process was revealed. The effect of interruption of the buckling process was observed in the specimen with non-uniform distribution of basic cells. And because of that the structure continued to work in compression. In other words, the lattice architecture "dampened " the bending components of the displacement vector.

One of the main problems in the nonlinear dynamics of DNA is the identification of physical mechanisms responsible for the mechanical features of its behaviour. The formation and interaction of open states in the DNA structure may be one such mechanism. In this paper we propose a mathematical model of native DNA, which allows us to describe its thermodynamic and kinetic properties taking into account the collective behaviour of the ensemble of open states. The concept of a microscopic open state in DNA and its associated parameter, the displacement vector of nitrogenous bases, are introduced. By averaging the base displacement vectors over the ensemble of states, the thermodynamic variable is determined. According to the statistical model of DNA in the self-consistent field approximation, the structural parameter of the system thermalization is derived. This parameter reflects the statistical self-similarity in the behaviour of the ensemble of open states. Regularities of "criticality" for different ranges of the structural parameter are established and phenomenological representations of the free energy in the framework of the Ginzburg-Landau approach are proposed. Numerical modelling of the dynamics of native DNA is carried out for different ranges of the structural parameter, which has allowed us to establish the types of self-similar solutions and the corresponding open-state collective modes. It is shown that the latter have the nature of finite-amplitude fluctuations in the form of breahters and autosoliton modes, as well as blow-up dissipative structures. The sensitivity of the model to initial conditions is investigated, and the influence of nonlinearity inherent in the model on the modelling results is established. The limitations and prospects of using the approach proposed in this work for mathematical modelling of native DNA are discussed.
