Obtaining wheat grain with good baking qualities is an important part of the food security of the Russian Federation. An important link in the production of grain is the development of winter common wheat varieties, which have genetically determined quality characteristics. FSBSI “FRC “Nemchinovka” is a leading institute for the development of strong and valuable winter wheat varieties. In recent years, the most spread varieties of winter common wheat developed by “Nemchinovska” are ‘Moskovskaya 39’, ‘Moskovskaya 56’ and ‘Nemchinovskaya 85’. The purpose of the current work was to study productivity and quality indicators of these varieties during the with years different weather conditions (according to the Competitive Variety Testing in 2015–2022). The most productive variety is ‘Nemchinovskaya 85’, the mean productivity is 7.35 t/ha, exceeding the standard ‘Moskovskaya 39’ on 1.47 t/ha with its maximum of 12.14 t/ha. According to the considered qualitative indicators, there was identified the variety ‘Moskovskaya 39’ with 15.9 % of protein in grain, 34.8 % of gluten in grain, 72.6 u. appr. of IDK, 350 u.a of strength of flour on the alveograph, 72 u.val. of valometric estimation, 1003 cm3 of volumetric yield of bread. The varieties ‘Moskovskaya 56’ and ‘Nemchinovskaya 85’ had quality indicators corresponding to valuable and strong wheat. There was found that the variety ‘Nemchinovskaya 85’ was the most variable over the years of the study (CV 8.0–18.9 %). The strength of flour on the alveograph differed to the greatest extent both according to the factors ‘variety’ and ‘year’ (17.1 %; 15.4 %; 17.6 %). There was identified that the volumetric yield of bread was the least variable indicator (5.5 %; 14.0 %; 8 %). When estimating the correlations, there was established a strong negative relationship between productivity and protein percentage in grain, similar in three varieties, and a mean positive correlation between productivity and IDK.

Authors: Fadeeva I. D.
Published: July 2023

Winter wheat occupies significant areas in the fields of the Republic of Tatarstan. The purpose of the current paper was to develope a new winter common wheat variety ‘Sultan’ and to identify its ability to produce not only high yields, but also grain quality in the conditions of the Republic. The study was carried out on the fields of the TatRIA, a separate structural subdivision of the FRC KazSC RAS on gray forest soil when sown on bare fallow at the optimal time for this area. The paper has presented the characteristics of the variety according to economically valuable traits during the years of study (2018–2020). The variety was developed by the method of individual selection from a hybrid population (Kazanskaya84 х Moskovskaya39) х Kazanskaya 285. According to the productivity, the new variety ‘Sultan’ has exceeded the standard variety ‘Kazanskaya 560’ by 0.75 t/ha. There has been established that the large productivity of the variety ‘Sultan’ is formed due to the density of the productive stem, large number and weight of grain per ear. The variety is characterized by high frost-winter resistance (90 % on average over three years of trials), can withstand a temperature decrease at the level of the tillering node to minus 20°C in winter. The variety has a high reparation ability in spring. The variety ‘Sultan’ forms well-filled grain with a grain unit of 780–801 g/l. Crude protein in grain is of 14.9–15.6 %, and 26.8–28.5 % of gluten. The variety has high values of rheological properties, namely the specific work of dough deformation according to the alveograph (flour strength) is 275 e.u., the valorimetric value is 60 %. On average, over the three years of the study, the volume yield from 100 g of flour was 576 ml3, the general baking assessment was 4.6 points. The variety can be recommended for cultivation in the south-east of the Republic of Tatarstan.

Published: July 2023

Background:

The incidence and prevalence of liver disease are increasing and contribute to significant morbidity and mortality. In Canada, more than 3 million people live with liver diseases, accounting for approximately 2% of all hospitalizations. However, it remains unclear how much liver hospitalizations cost the Canadian health care system. Thus, this study estimates the cost of liver-related hospitalization across Canada.

Methods:

We conducted a population-based, retrospective study using acute inpatient admission data for liver-related hospitalizations obtained from the Canadian Institute for Health Information. We calculated the total and the average nominal spending for liver hospitalizations nationally from April 1, 2004, to March 31, 2020, based on fiscal year (FY). In addition, we stratified the average liver hospitalization spending based on age and sex group.

Results:

Canada spent $947 million on liver-related hospitalizations in FY2019, a 145% growth in spending from FY2004. The average liver disease–related hospitalization was estimated to be $17,506 in FY2019. Within the sub-group analysis, the age group <30 showed the highest average cost per hospitalization at $21,776; however, there was no significant difference in cost between males and females. Across the different provinces in FY2019, Alberta experienced the highest average spending per hospitalization at $23,150, whereas Ontario had the lowest spending at $15,712.

Conclusions:

Liver-related hospitalizations are associated with high spending that is increasing nationally with variations across provinces and territories. Our results are of great use for economic evaluations of novel interventions in the future.

Published: July 2023

The work is devoted to the theoretical development of miniature highly sensitive electron spectrometer for the analysis of the composition of corpuscular flows in a wide range of measured particle energies. The mirror type axially symmetric energy analyzerin the spectrometer is constructed on the basis of an electrostatic octupole-cylindrical field and has a long-focal-length distance. The focusing properties of the scheme have been calculated, and the luminosity and resolving power of the device have beenevaluated. As part of a set of equipment for spacecrafts, the proposed device will allow to determine the composition of charged particles in unsteady flows in interplanetary space. Also when designing the device there is a possibility to combine several methods of analysis (for example, with mass-spectrometric methods), which will successfully complement each other, which will provide high information content of joint analysis. This tendency is observed in the creation of space research complexes, which, as a rule, include several independent methods of analysis.

Published: July 2023

Aramide-epoxy-filled composites are widely used for manufacturing in the structures of modern aerospace vehicles. Not only do they have excellent mechanical properties, but they are also radio-transparent materials for wave transmission. In this work, an epoxy-filled composite and a fibreglass were made by vacuum infusion for a comparative study on radio transparency and dielectric permittivity. The radio transparency of the materials analyzed has been evaluated by measuring in free space in the frequency ranges of 1-6 GHz. According to the results of radio transparency, aramide-epoxy-filled composite suffers less electromagnetic wave losses than in fibreglass. When measuring the dielectric permittivity of the aramide-epoxy-filled composites, a low average value of 2.874 has been set, whereas for the fibreglass is defined at 4.

Authors:   Department of Physics, University of Calabar, Calabar, Nigeria, Iwuji P.C.
Published: July 2023

It is impossible to overstate the importance of propagation models in wireless network planning, frequency assignment, and television parameter evaluation. The fact that no two locations are identical in terms of climatic conditions, building patterns, terrain, etc. makes using path loss predicting models for any area extremely challenging. Therefore, it is impossible to develop a single path loss model that applies to all environmental settings. The main aim of this study is to develop a path loss model for NTA channel 12 Owerri and evaluate its performance based on received signal strength values along five selected routes in Imo State, Nigeria.A suitable path loss model was developed by critically analyzing the measured path loss values of each base station, which were retrieved from the signal strength data received. The values of the developed path loss model were compared to those of other empirical path loss models developed by other researchers as well as the measured path loss values. The results show that the proposed path loss model is well suited for predicting the path loss of NTA channel 12 Owerri signals in the study environment, while the other conventional empirical models taken into consideration in this study overestimated the path loss of NTA channel 12 Owerri signals with Root Mean Square Error and Mean Error of 63.65 and above. Additionally, the findings indicate that NTA Owerri performs poorly at a distance of 18 kilometers from the base transmitting station. The overall findings are helpful for designing prospective television network channels in the study location and other similar environments.

Regional integration organizations (RIOs) have long been an important mechanism for cooperation among States. With their ever- closer ties, concerns about the regimes of the States involved have led RIOs to adopt norms for sanctions or suspension from these organizations when irregular regime changes occur, or governments become undemocratic. This article reflects on the development and enforcement of these tools based on two major cases for Europe and Latin America: the case of Venezuela in Mercosur and Hungary in the European Union. The conclusion is not supposed to plainly label processes as “succeeded” or “failed” but rather to provide observations on mutual learning through case studies to better reflect on the design of institutions, norms, adaptation, and political constraints to its enforcement.

Las organizaciones de integración regional (OIR) han sido durante mucho tiempo un importante mecanismo de cooperación entre países. Con sus lazos cada vez más estrechos, la preocupación por los regímenes de los países implicados ha llevado a las OIR a adoptar normas de sanción o suspensión de estas organizaciones cuando se producen cambios irregulares de régimen, o los gobiernos se vuelven antidemocráticos. Este artículo reflexiona sobre el desarrollo y la aplicación de estas herramientas basándose en dos casos importantes para Europa y América Latina: el caso de Venezuela en el Mercosur y el de Hungría en la Unión Europea. La conclusión no pretende etiquetar lisa y llanamente los procesos como “exitosos” o “fracasados”, sino aportar observaciones sobre el aprendizaje mutuo a través del estudio de casos, para reflexionar mejor sobre el diseño de las instituciones, las normas, la adaptación y las limitaciones políticas para su aplicación.

Les organisations d'intégration régionales (OIR)ont longtemps représenté un mécanisme fondamental de coopération entre pays. En raison de leurs liens de plus en plus étroits, les inquiétudes concernant les régimes des pays concernés ont conduit les OIR à adopter des normes de sanction ou de suspension de ces organisations en cas de changements irréguliers de régimes ou non démocratiques de gouvernements. Cet article reflète le développement et l'application de ces mécanismes à partir de deux cas significatifs pour l'Europe et l'Amérique latine : le Venezuela dans le Mercosur et la Hongrie dans l'Union Européenne. La conclusion n'est pas censée qualifier les processus « d’échec » ou de « réussite » mais plutôt fournir des observations sur l'apprentissage mutuel à travers des études de cas afin de mieux réfléchir à la conception des institutions, aux normes, à l'adaptation et aux contraintes politiques de leur exécution.

Somatostatin and the pathophysiology of Alzheimer’s disease
Authors: N. Almeida Victor
Published: July 2023

Since early research on Alzheimer’s disease (AD), it has been known that among the central features of its progression are altered levels of the neuropeptide somatostatin, and the colocalisation of somatostatin-positive interneurons (SST-INs) with amyloid-β plaques, leading to cell death. In this theoretical review, I propose a model for the pathogenesis of AD that coheres with the qualitative profile of its neuropsychological deficits and neurobiological progression. Namely, hypofunctional and hyperactive SST-INs struggle to control hyperactivity in mid-temporal regions in early stages, leading excessive presynaptic GABA-B inhibition, GABA-B1a-APP complex downregulation and internalisation, thereby boosting Aβ production. Concomitantly, excessive SST-14 release accumulates near SST-INs in the form of amyloids, known to bind to Aβ to form toxic mixed oligomers. This leads to differential SST-IN death through excitotoxicity, further disinhibition, SST deficits, and increased Aβ release, fibrillation and plaque formation. Aβ plaques, hyperactive networks and SST-IN distributions thereby tightly overlap in the brain. Finally, SST-IN disinhibition reportedly induces neuropsychological deficits that qualitatively agree with those found in AD cohorts, with pattern separation and encoding deficits, mnemonic indiscrimination, interference and reconsolidation.

Published: July 2023

This concise paper discusses the potential benefits of combining Social Network Analysis (SNA) with Structural Equation Modeling (SEM) in sociological research. SEM is a valuable tool for examining mediation and moderation effects in integrated models. However, when variables exhibit mutual relationships, determining the specific roles of mediation and moderation becomes complex. To address this challenge, the paper proposes incorporating SNA into the analysis.
Cord blood albumin level as a predictor of neonatal physiological jaundice in healthy term neonate
Authors: Anupriya KS , Pradeep N
Published: July 2023

Background: Neonatal jaundice is a very common condition worldwide, occurring in up to 60% of term and 80% of pre-term newborns in the 1st week of life and the most common cause for readmission. The present study was conducted to evaluate the predictive value of umbilical cord blood albumin level for subsequent development of neonatal jaundice in healthy term neonates. The present study is conducted to find usefulness of cord blood albumin in predicting the subsequent development of significant neonatal jaundice. Methods and Methods: This is a hospital-based prospective study conducted in 100 healthy term neonates. Cord blood albumin level estimation was done at birth. Total serum bilirubin estimation was done for all babies with clinically suspected jaundice at 72–96 h of age. The neonates were divided into three Groups A, B, and C based on the cord albumin levels of <2.8 g/dL, 2.8–3.3 g/dL, and >3.3 g/dL, respectively. The main outcome of the study was inferred in terms of serum bilirubin ≥17 mg/dL, newborn required phototherapy, and exchange transfusion. Results: Groups A, B, and C had 21, 35, and 44 newborns, respectively. In Group A, 18 (85.7%) neonates had total bilirubin of >17 mg/dL, of which 16 (76.19%) required phototherapy and 2 (9.52%) needed exchange transfusion. 23 (65.7%) neonates in Group B developed jaundice, of which 12 (34.2%) needed phototherapy and none of them required exchange transfusion. In Group C, 15 (34.09%) developed jaundice of which 1 (2.2%) required phototherapy and none of them required exchange transfusion (p<0.001). Conclusion: Cord blood albumin level ≤2.8 g/dL is a significant risk factor for developing neonatal hyperbilirubinemia that requires early intervention, while cord blood albumin >3.3 g/dL is probably safe for early discharge. Hence, this can help to identify the at-risk neonates. Hence, routine determination of cord blood albumin level can be advocated to keep a track on at-risk neonates.

Published: July 2023

A 60-year-old male patient who presented with generalized weakness and low-grade fever was diagnosed to be human immunodeficiency virus (HIV) positive with a CD4 count of 17. Routine laboratory investigations revealed pancytopenia. Serum cytomegalovirus (CMV) DNA polymerase chain reaction (PCR) was positive and fundoscopy showed CMV retinitis in the right eye. The patient was started on tablet valganciclovir. After 2 weeks, the patient was brought back in an altered sensorium. He was found to have hyponatremia which was corrected. He was started on antiretroviral therapy and tablet valganciclovir was continued. The patient came back again after one and a half months with a urinary tract infection and fissure-in-ano. He was found to have severe neutropenia. Valganciclovir was stopped. He was started on injection granulocyte colony-stimulating factor. The patient clinically improved and his hematological parameters became normal. Patients having HIV and CMV co-infection with pre-existing pancytopenia have to be closely monitored as the medicines used for treatment can exacerbate the existing conditions.

External fibrillation of wood pulp
Authors: KEREKES RICHARD J. , MCDONALD DAVID , MELTZER FRANK P.
Published: July 2023

Pulp refining produces external fibrillation consisting of fibrils tethered to fiber surfaces, in addition to loose fibrils and fines. Both contribute to a larger bonding area that increases paper strength, but tethered fibrils have less likelihood of being washed out during papermaking. This study postulates the mechanism by which refining produces external fibrillation and the optimum conditions for doing so. The postulated mechanism is surface abrasion during sliding of fibers in refiner gaps. External fibrillation occurs when forces are great enough to partially dislodge fibrils from fiber surfaces, but not large enough to break the fibrils. The refining intensities to achieve these forces were determined by a mathematical model and experiments using a laboratory disc refiner. The optimum intensities in terms of specific edge load (SEL) for chemical pulps were about 0.1 J/m for hardwoods and 1.0 J/m for softwoods An extension of this study suggested that abrasion may also account for most of the energy consumed in the mechanical pulping process.
MOTION AROUND THE EQUILIBRIUM POINTS IN THE PHOTOGRAVITATIONAL R4BP UNDER THE EFFECT OF CIRCUMSTELLAR BELT
Authors: Vincent Aguda Ekele , Taura Joel John
Published: July 2023

In the present work, we study numerically the motion of an infinitesimal fourth body near the equilibrium points (EPs) of the photogravitational restricted four-body problem (Lagrangian configuration) under the effect of circumstellar belt. We consider the case where  three the bodies of masses and  (primaries) are sources of radiation as well as enclosed by a circumstellar belt and two of the primaries, and, have equal masses () and equal radiation factors () while the dominant primary body is of mass  Firstly, these equilibria are determined and then the influence of the system parameters on their positions and stability is performed. In addition, the numerical exploration is performed using the Ross 104-Ross775a-Ross775b stellar system to compute the locations of the equilibria and the eigenvalues of the characteristic equation. For this system where the value of the mass parameter is beyond Routh’s value, we observe that they may be ten (four collinear and six non-collinear) or eight (two collinear and six non-collinear) EPs depending on the mass of the circumstellar belt. The linear stability of each equilibrium point is also studied and it is found that in the case where ten equilibria exist, the new collinear point, is always linearly stable while the other nine equilibria are always linearly unstable. In the case where eight equilibria exist, all of them are always linearly unstable. The zero velocity surfaces for the stellar system are drawn and regions of motion are analyzed for increasing values of the mass belt.

Liquid herbal products are highly prone to microbial deterioration due to high content of organic matter. The aim of this study was to carry out 90 days microbial stability study of a bi- herbal syrup formulated from extracts of Citrus aurantifolia (CA) whole fruits and Garcinia kola (GK) seeds. The bi-herbal syrup was formulated based on combined extracts minimum bactericidal concentrations (MBC): 8.33mg/mL GA, 30.42mg/mL GK and excipients and compounded by agitation without heat method. Both the preserved and unpreserved samples were challenged with determined population of organisms and counts taken at 7th, 14th and 28th day after inoculation. The zones of growth inhibition (ZGI) and MBC retention of the syrup were determined by Agar well diffusion and Agar–extract–inoculum pour plate methods respectively and the same procedure repeated 60th and 90th days of compounding.There was a slight decline (8.88 %) in the average percentage change of antibacterial activities (ZGI) of the optimum formulation (F3) in a period of 90 days. Only formulation 3 recorded five colonies at the 90 days of compounding. The microbial challenged of the preserved and unpreserved syrup yielded no growth on the 7th, 14th and 28th days, after inoculation. Preservative has no significant contribution to the microbial stability of the formulation, as the unpreserved bi-herbal syrups were much stable within 90 days of stability study and in case of inadvertent introduction of microbes, both preserved and unpreserved syrup would resist microbial growth.

Road infrastructure is one of the critical infrastructure because it shapes the spatial structure of socio-economic activities and the well-being of the people. This study aims to bring out the correlation of the impact of road infrastructure on population and economic growth in Kaduna metropolis. A qualitative method using a thematic approach was used to collect data and analyze them. 46 participants were interviewed. From the analysis or results, two schools of thought emerged in connection with road infrastructure and population and economic growth. The first school of thought opines that road infrastructure is directly correlated with positive population and economic growth. This group is dominated by government agencies and transport functionaries. The second school of thought dominated by traders and consumers of goods did not see  correlation between road infrastructure and economic growth owing to the displacement of small businesses by the roadside and the increase journey to get or purchase goods.  However, irrespective of individual and/or collective views, the government of Kaduna State is trying to meet up with the sustainable development goals eight, nine and eleven which are directly connected  to decent work and economic growth; industry, innovation and infrastructure and sustainable cities and communities respectively. Thus, more findings reveal many roads either rehabilitated or constructed including underpass and overpass bridges across the metropolis including a four- hectare big shopping mall. It is recommended that government should be cautious when implementing this noble idea so that less injury is/will be inflicted on small-scale business owners and consumers.
Predictive Identification of At-Risk Students: Using Learning Management System Data
Authors: Osborne J Bryan , Lang Andrew S.I.D.

This paper describes a neural network model that can be used to detect at-risk students failing a particular course using only grade book data from a learning management system. By analyzing data extracted from the learning management system at the end of week 5, the model can predict with an accuracy of 88% whether the student will pass or fail a specific course. Data from the grade books from all course shells from the Spring 2022 semester (N = 22,041 rows) were analyzed, and four factors were found to be significant predictors of student success/failure: the current course grade after the fifth week of the semester and the presence of missing grades in weeks 3, 4, and 5. Several models were investigated before concluding that a neural network model had the best overall utility for the purpose of an early alert system. By categorizing students who are predicted to fail more than one course as being generally at risk, we provide a metric for those who use early warning systems to target resources to the most at-risk students and intervene before students drop out. Seventy-four percent of the students whom our model classified as being generally at risk ended up failing at least one course.

Jalan memiliki manfaat yang besar guna proses mobilitas kendaraan pada suatu daerah agar lebih aman, nyaman, dan lancar sehingga perlu kondisi jalan yang baik dengan perkerasan jalan yang tepat. Penelitian dilakukan guna mengetahui kadar aspal optimum yang digunakan dalam pencampuran limbah marmer sebagai filler dan mengetahui pengaruhnya pada Ketahanan Deformasi. Terbentuknya rutting disebabkan oleh banyaknya lintasan secara berulang serta berat beban yang melewati perkerasan jalan. Jenis deformasi ditunjukkan dengan adanya bentuk yang berubah pada permukaan jalan yang diakibatkan lalu lintas kendaraan pada bagian perkerasan jalan. Penggunaan kadar aspal rencana yakni 4,5%, 5,0%, 5,5%, 6,0%, dan 6,5%. Uji yang dilakukan pada awal yakni Marshall Test guna memperoleh kadar aspal optimum (KAO), yang selanjutnya di uji dengan alat Wheel Tracking. KAO yang dipergunakan yakni 5,9% dengan kadar filler 0%, 1%, 2%, 3%, dan 4%. Dari hasil pengujian Wheel Tracking, penggunaan campuran filler marmer varisi 1% dapat menahan beban sebanyak 0,49%. Oleh karena itu marmer bisa digunakan sebahan bahan tambah pada campuran karena dapat meningkatkan ketahanan deformasi sehingga campuran lebih kuat saat menerima beban dari lalu lintas.
