BACKGROUND AND OBJECTIVES
The Community Eligibility Provision (CEP), a universal free school meals policy, increases school meal participation by allowing schools in low-income areas to provide free breakfast and lunch to all students; however, its impact on obesity remains uncertain. The objective of this study is to estimate the association of CEP with child obesity.

METHODS
School obesity prevalence was calculated using BMI measurements collected annually between 2013 and 2019 from students in California public schools in grades 5, 7, and 9. To estimate the association of CEP with obesity, we used a difference-in-differences approach for staggered policy adoption with an outcome regression model conditional on covariates, weighted by student population size.

RESULTS
The analysis included 3531 CEP-eligible schools using school-level obesity prevalence calculated from 3 546 803 BMI measurements. At baseline, on average, 72% of students identified as Hispanic, 11% identified as white, 7% identified as Black, and 80% were eligible for free or reduced-price meals. Baseline obesity prevalence was 25%. Schools that participated in CEP were associated with a 0.60-percentage-point net decrease in obesity prevalence after policy adoption (95% confidence interval: −1.07 to −0.14 percentage points, P = .01) compared with eligible, nonparticipating schools, corresponding with a 2.4% relative reduction, given baseline prevalence. Meals served increased during this period in CEP-participating schools only.

CONCLUSIONS
In a balanced sample of California schools, CEP participation was associated with a modest net decrease in obesity prevalence compared with eligible, nonparticipating schools. These findings add to the growing literature revealing potential benefits of universal free school meals for children’s well-being.

Introducción. Canavalia ensiformisampliamente utilizada como abono verde, presenta beneficios comprobados por la inoculación micorrízica. La efectividad de los inoculantes micorrízicos arbusculares utilizados en Cuba dependen de la condición edáfica en que se desarrolla el cultivo; sin embargo, hay pocos resultados experimentales en suelos Cambisol éutrico crómico de Jibacoa. Objetivo. Evaluar en este suelo la respuesta de la canavalia a la aplicación de 3 inoculantes micorrizicos. Materiales y métodos. La investigación se realizó en la Estación Experimental Agro-Forestal de Jibacoa, provincia Villa Clara, Cuba. En un diseño completamente aleatorizado se estudiaron 3 inoculantes formulados con las cepas INCAM2/Funneliformis mosseae, INCAM-4/Glomus cubense e INCAM-11/Rizhophagus irregularis y un control sin inocular. En el momento que floreció la canavalia se evaluó: la cantidad de nódulos efectivos; la altura; la masa seca de la raíz, del tallo, de las hojas, la total y se determinó el índice de eficiencia. Resultados. La canavalia presentó una respuesta positiva y diferenciada a la inoculación micorrízica. La inoculación con INCAM-2 incrementó significativamente la cantidad de nódulos efectivos (21,9%) con valores superiores al tratamiento control y a la inoculación con INCAM-4, además originó la mayor altura con aumentos del 66,1%, superiores (p<0,05) a las encontradas con los otros inoculantes. INCAM-2 siempre provocó valores superiores de masa seca (p<0,01) en cualquiera de los órganos y la total en relación con el tratamiento control, no obstante, no se diferenciaron (p<0,01) a los obtenidos con los otros inoculantes, los cuales no siempre se diferenciaron del tratamiento control. La respuesta se ordenó de acuerdo con la masa seca total como sigue: INCAM-2 con 71,90% > INCAM-11 con 50,17% > INCAM-4 con 38,29%.

The aim of the work was to develop a simple, rapid, economic spectrophotometric method for the determination of meldonium in capsules based on the reaction with alizarin.
Materials and methods. Analytical equipment: double-beam UV-visible spectrophotometer Shimadzu UV 1800 (Japan), a pair of 1 cm matched quartz cells, software UV-Probe 2.62, laboratory electronic balance RAD WAG AS 200/C, pH-meter И-160МИ. Pharmacopoeial standard sample (CRS) of meldonium dihydrate (Sigma-Aldrich, (≥ 98 %, HPLC)), alizarin (Synbias), capsules Metamax (Darnytsia) 250 mg, Vasopro (Farmak) 500 mg, Mildronate (Grindex) 500 mg, dimethylformamide (“Honeywell Riedel-de Haen”).
Results and discussion. A spectrophotometric method for determining meldonium in capsules by reaction with alizarine has been developed. The absorption maximum of the formed complex in dimethylformamide was at a wavelength of 517 nm. Stoichiometric ratios of reactive components «meldonium- alizarin» were 1:1. Validation of the developed analytical method for the determination of meldonium in medicines was carried out in accordance with the requirements of the SPhU. The optimal conditions for performing the quantitative determination of meldonium have been established: concentration of alizarin solution – 0.8 %, volume 0.8 % alizarin solution – 0.5 ml, heating time – 20 min, temperature – 95+/- 2 °C. Linearity has been in the concentration range of 0.0402- 0.1073 mg/mL, the limit of detection - 2.84 μg/mL, and the limit of quantification – 8.59 μg/mL. The eco-friendliness of the developed analytical method was carried out using the analytical eco-scale, AGREE, and GAPI methods.
Conclusions. The developed method can be used as an arbitration method for the routine analysis of meldonium capsules

Anxiety disorders are the most prevalent psychiatric disorders and are associated with a high burden of illness. Combining synthetic and native-origin compounds in treating such disorders could provide true benefits in terms of therapeutic efficacy. In the present study, we combined triazolobenzodiazepine and motherwort (Leonurus cardiaca L.) dry extract for such applications.
The aim. The aim of this study was to develop aqueous polyethylene oxide (PEO) composite gels loaded with 1,2,3-triazolo-1,4-benzodiazepine nanofibers and a valine-modified motherwort herb dry extract for semi-solid extrusion (SSE) 3D printing. The printability of such gels and the physicochemical properties of the final 3D-printed drug preparations were investigated.
Materials and methods. A new drug substance, 1,2,3-triazolo-1,4-benzodiazepine (MA-253) was synthesized and used to formulate oleogels and electrospun nanofibers for 3D printing. The plant-origin dry extract was prepared from a motherwort tincture and valine. The aqueous PEO gels loaded with a synthetic drug (MA-253) containing nanofibers and a valine-modified motherwort extract were prepared and subsequently used in the SSE 3D printing experiments. The homogeneity, viscosity and 3D printability of composite PEO gels were verified. The phytochemical assay of flavonoids in the 3D-printed drug preparations was conducted with the European pharmacopoeia spectrophotometric method.
Research results. Three experimental gel formulations loaded with 1,2,3-triazolo-1,4-benzodiazepine nanofibers and a valine-modified motherwort dry extract were developed and tested for the SSE 3D printing applications. The present three gels showed good SSE 3D printability without any significant printing flaws. The SSE 3D-printed lattices prepared from the aqueous PEO gels containing 100 mg/ml of motherwort extract showed the most promising 3D printing performance. The 3D-printed drug preparations were entirely dissolved in purified water (22±2 °C) within 20 minutes, thus suggesting their applicability in oral administration.
Conclusions. Novel aqueous PEO gel formulations loaded with nanofibrous 1,2,3-triazolo-1,4-benzodiazepine nanofibers and valine-modified motherwort herb extract are feasible for pharmaceutical SSE 3D printing. The present composite PEO gels enable the preparation of printed oral immediate-release drug delivery systems for new triazolobenzodiazepine derivatives and a drug therapy supportive plant extract

Authors: Sumenko Tеtiana 
Published: March 2024

The article presents the author's own practical experience and description of experimental work with children with complex disorders (autism, ADHD, intellectual disability, Down syndrome, childhood schizophrenia, cerebral palsy). The author has created his own method of forming the social competence of children with complex developmental disorders, implemented as part of an experiment within a rehabilitation institution. The essence and advantages of social larping are defined. The scientific studies related to the research topic are briefly reviewed. The method of forming social competence for autistic children - Creative drama - is analysed. A comparative analysis of the method of "live" game LARP and Creative drama is carried out. The concept of "social larping" is defined for the first time. The criteria and indicators of the level of formation of the social competence of children with complex developmental disorders are outlined (cognitive: knowledge of ways of behaviour, rights and responsibilities; basic ideas and knowledge to meet their own needs; knowledge of ways of social interaction; emotional and motivational: understanding of emotions, self-control skills (self-esteem), social values; behavioural: social interaction, orientation in social roles, social skills). The descriptive characteristics of the levels of formation of the social competence of children with complex developmental disorders in accordance with the above criteria are provided.
The importance of introducing social larping as an author's method of forming the social competence of children with complex developmental disorders within the correctional and developmental work of rehabilitation institutions is proved. The impact of social larping on improving the interaction between children with complex developmental disorders within a mini-group, catching up with the child's own social experience in a rehabilitation centre is analysed.
The conclusions and suggestions demonstrate the essence and advantages of social larping as a method of forming the social competence of children with SCD, as well as the effectiveness of its implementation

Published: March 2024

The establishment of a new metallurgical complex in Bellara, located in El-Milia in the Jijel region, is geographically advantageous due to its proximity to the Sidi Maarouf deposit (Algeria). This proximity has been a fundamental motivation for the completion of the current study. The object of research is the quality of iron products from Sidi Maarouf. The research is aimed at developing a treatment process aimed at improving the quality of iron products from Sidi Maarouf, while reducing the impurities of quartz and clay present in this ore. This approach will be based on an approved technological treatment scheme, implemented through an experimental approach to ensure reliable results that meet the requirements of the steel industry. The problem issue revolves around the difficulties encountered in the production of steels due to the natural characteristics of the raw material.
In the absence of a physico-chemical characterization of the Sidi Maarouf iron ore deposit, samples taken undergo a series of thorough analyses, including microscopic examinations, X-ray diffraction (XRD), as well as additional chemical analyses using X-ray fluorescence (XRF). The identified minerals are predominantly composed of hematite in terms of iron. As for the gangue, it is mainly composed of calcite and quartz. Through to the pre-treatment process involving washing, we have successfully removed lightweight particles, resulting in a concentrate containing dense particles. This approach was crucial in achieving satisfactory results during the high-intensity dry magnetic separation. As a result of the research it is shown that the enrichment of the Sidi Maarouf iron ore through high-intensity dry magnetic separation, a final concentrate was obtained with a Fe2O3 content exceeding 67 %, along with a significant reduction in silica impurities to 0.92 % and alumina to 0.77 %. It was concluded that this concentrate, derived from the -1+0.5 mm fraction and obtained under a current intensity of 12 A, meets the requirements of the steel industry.
Following the work carried out, it is found that the methods of valorization of iron ore through mineralogical processes consistently require a high level of efficiency and performance in terms of equipment and characterization of the products obtained. In the future, iron ore processing will be conducted using innovative methods, integrating advanced technologies to enhance its characteristics while adopting environmentally friendly practices.
Determination of the features of integrated design of civil long-range aircraft with transonic truss-braced wing at the preliminary design stage
Authors: Pelykh Valentyn , Andryushchenko Volodymyr 
Published: March 2024

The object of research is a civil mainline aircraft with a transonic truss-braced wing. The problem of designing an aircraft of this scheme at the preliminary design stage is being solved in the work. The results of the work include the concept of designing aircraft with a transonic truss-braced wing, the main advantages of such a scheme, the process of determining the geometric parameters of the truss-braced, features of the preliminary design of an aircraft with an extremely high aspect ratio truss-braced wing, possible approaches to the arrangement of units and their mutual arrangement. The results are explained by the difference in the design model (the cantilever beam is replaced by a beam on two supports) in mass analysis and the increased wing aspect ratio in aerodynamic calculation. The final data are based on a statistical study to determine the basic geometric parameters of assemblies of modern mainline passenger aircraft, synthesis of parameters of analog aircraft. For example, an aircraft capable of carrying 250 passengers over a distance of 13.000 km is considered. In the design process, values of aspect ratio, taper ratio, wing area, vertical tail and horizontal tail area ratio, and fuselage dimensions are accepted. Drawings of the general appearance of the aircraft have been developed and, based on it, a master geometry of the theoretical contour has been constructed. Graphs of first-order polar and maximum lift-to-drag ratio have been plotted, the reduction of aerodynamic drag in percentage terms has been determined, and the increase in aerodynamic lift-to-drag ratio in percentage terms for an aircraft with an extremely high aspect ratio truss-braced wing compared to similar characteristics of an aircraft with a conventional non-braced wing has been calculated. The approximate mass savings when using a truss-braced wing on the aircraft are determined in percentage terms. The expediency of using wings of greater aspect ratio, than modern aircraft currently have, has been justified. The expediency of using a brace for the aircraft with an extremely high aspect ratio wing has been justified. The obtained results can be used in practice in the process of developing the preliminary design of an aircraft with a truss-braced wing or in the modifications of existing aircraft to increase their fuel efficiency or increase the durability of wing elements due to reduced loads acting on them.
Peculiarities of Advertising Banking Operations: Models 4P and 2S
Authors: Kondratskaya Tatiana , Shagina Ekaterina , Kondratskaya Galina 
Published: March 2024

The article summarizes the results of the theoretical and practical researches in the field of the advertising carried out by the universal financial organizations. The motivation was the established trend of presenting the bank’s operations to customers in advertising as a product possessing the properties of both goods and services. It contradicts the classical theory of the services laid down by the works of F. Kotler, K. Lovelock, E. Gammesson, K. Grönroos. The paper proposes the reason that explains the phenomenon. It is related to the failure to respect the characteristics of services, such as lack of ownership and intangibility. The article justifies the reason of tangibility, connected with the miscalculation of the results from the conduct of banking operations by the client. Taking into consideration this feature the bank declares competitive advantages in the terms of the 4P product model in the advertising. The paper uses the method of analyzing the advertising messages in the online and offline environments.
The generalization of the advertising activities experience is considered on the example of one of the universal banks of the Russian market — JSC Raiffeisen Bank. Its achievements in the field of its profits for 2022 draw attention to the advertising carried out by the bank and its object and subject. The study revealed the use of the 4P model for the mass market and the special model for the business one. The latter was called 2S by the authors, since it includes a service operation (the object of the advertising) and special conditions which are the benefits (time, privileges, technologies) as the subject of the advertising. The obtained results can be used in the promotional activities of any universal bank, since its operations are standard.
Identifying High-Risk ZIP Codes for Childhood Lead Exposure: A Statewide ZCTA-Level Priority List for North Carolina

Published: March 2024

Background Research has consistently shown that there is no safe blood lead level (BLL) for children. Despite progress in lead poisoning prevention, lead exposure remains a persistent threat to the health and neurological development of children. To identify high-risk ZIP codes for use by families and health care providers for the entire state of North Carolina, we developed a risk model using ZIP Code Tabula­tion Area (ZCTA)-level census data. Methods We obtained all available BLL testing data from the North Carolina Department of Health and Human Services for the years 2010–2015 via data use agreement. We fit a multivariable regression model with the ZCTA-level mean of log normalized BLLs as the de­pendent variable and ZCTA-level census data for known risk factors of childhood lead exposure as predictors. We used this model to create a priority risk categorization. Results We organized ZCTAs into 20 quantiles, or priority risk categories, that can be used in local and statewide screening programs. The first six (of 20) quantiles were identified as particularly high-risk areas for childhood lead exposure. Limitations Because BLL testing is not universal, the BLL testing data used in this study are likely biased toward those most at risk for lead exposure. Conclusion This study demonstrates the utility of ZCTA-level census data in identifying high-risk ZIP codes for childhood lead exposure, which can be used to ensure that the highest-risk children are tested in a timely manner. This approach can be replicated to address lead exposure nationally.

Forage plants are one of the main aspects in the conservation management of the Sumatran elephant. Anatomical studies of elephant food plants can provide reference data needed in identifying the diversity of elephant food plants, especially in the studies with faecal samples. This study aims to provide anatomical data of Sumatran elephant feed plants. The observed samples consisted of leaf samples from 24 species and stem samples from four species. Samples were prepared for microscopic paradermal section using the wholemount method. The results showed that rectangular epidermal cell shapes were found in samples of Poaceae leaves, Cyperaceae leaves and stems, and Arecaceae leaves. Stomata with dumbbell-shaped guard cells were only found in Poaceae leaf samples and Cyperaceae leaf and stem samples. The presence of silica cells and cork cells distinguished the Poaceae samples from Cyperaceae. Other leaf samples had qualitative anatomical characteristics that varied based on anticlinal walls of epidermal cells, type of stomata, and trichomes. Quantitative characterization of epidermal cell size; stomatal size, density, and index; and trichome density are used to complete the species description and distinguish species that have the same qualitative characteristics.
