Authors: Lee Morgan P , Frenk Artem , Gupta Karish , Pham Thinh , Croteau Ethan , Heffernan Neil Thomas
Published: October 2024

Knowledge Tracing (KT) has been an established problem in the educational data mining field for decades,and it is commonly assumed that the underlying learning process being modeled remains static. Giventhe ever changing landscape of online learning platforms (OLPs), we investigate how the constructs ofconcept drift and code decay can impact student behavior within an OLP through testing model perfor-mance both within a single academic year and across multiple academic years. Four well-studied KTmodels were applied to five academic years of data to assess how susceptible KT models are to conceptdrift. Through our analysis, we find that all four families of KT models can lose accuracy with time,and that the relationship between model complexity and susceptability to concept drift is not as simple aspreviously theorized. Code used to conduct our analyses is available at https://github.com/ASSISTments-IQP/LongitudinalKnowledgeTracing24/tree/master, and the data at https://osf.io/hvfn9/.
From the Metaverse to the Tower of Babel: Investigating the Socio-Cultural Exclusion of Non-Native English Speakers on Social VR Platforms
Authors: Waligórski Jan
Published: October 2024

Social virtual reality (VR) platforms are emerging as new spaces for computer-mediated communication between people from different parts of the world. However, international communication remains underexplored in laboratory-based research, and existing field studies have predominantly included English-speaking social VR users, thereby marginalizing other perspectives. This study employs ethnographic methods to examine the challenges experienced by Polish users in communication with individuals of different nationalities. Findings indicate that international communication in social VR can present new challenges for Polish users. These challenges, related to communication in a foreign language, may be amplified by the immersiveness of head-mounted displays, the dominance of English-speaking nationalities, the prevalence of voice-based communication, cultural differences, and geographical location. Our results highlight the risk of excluding non-native English speakers from global communities in English-dominated social VR environments. Research underscores the need for a methodological shift in future studies on social VR platforms.
Developmental differences in hippocampal long-axis contributions to memory precision
Authors: Vijayarajah Sagana , Schlichting Margaret
Published: October 2024

Memory precision varies along the hippocampal long axis in the mature brain. Yet, little is known about how developmental change in long-axis functionality influences this precision. We characterized how children and adults engage the hippocampal long axis to form precise memories. Children (7-9 years) and adults performed two tasks that encouraged an orientation to the specific details versus broader category of scenes during encoding. They then performed a recognition test with studied scenes and similar lures. Adults had more precise memories than children, in that they were better able to discriminate studied scenes from lures; yet, both age groups benefited from orienting to specifics. Examining hippocampal engagement during both tasks showed a developmental shift from posterior to anterior hippocampus during specific encoding. Subregion engagement was also differently related to memory quality in children versus adults: While posterior hippocampus supported subsequent memory across age groups, both anterior and posterior hippocampus showed developmental differences in their link to false memories. Individual differences in the source of specific encoding along the long axis revealed that premature shifts towards an adult-like profile were disadvantageous to children’s memory. Our results suggest as development unfolds, refinements to both anterior and posterior subregion functionality supports memory imprecision.
On the problem of the interpretation of symbols and symbolism in archaeology
Authors: Coolidge Frederick L. , Overmann Karenleigh A. , Wynn Thomas
Published: October 2024

This chapter discusses the use of the terms symbols, symbolism, and symboling in the archaeological literature. The lack of definition and any grounding in cognitive theory makes identifying prehistoric symbols and symboling more art than science. A multiplicity of claims from the literature highlight the tendency to claim almost any form from any period of prehistory as symbolic. After the problem is defined, an alternative approach is proposed. The alternative suggests grounding symbols and symboling in contemporary cognitive theory; this would permit the construct to be operationalized as qualities potentially discernable in prehistoric material forms. A multi-level construct is also proposed, one that is not only capable of differentiating symbolic cognition as exhibited by the human species today from the presumably non-symbolic cognition of contemporary non-human primates but which is also able to differentiate both from the emergent symboling capacities of ancestral hominins.
Language endangerment in Vanuatu: Bislama poses a threat in the world’s most language-diverse country
Authors: Forsyth Guy A. Lavender
Published: October 2024

A quarter of a century has passed since the late Terry Crowley summed up the academic consensus that the creole language Bislama poses no immediate threat to any of Vanuatu’s Indigenous languages. Does this remain true today? Since that time, evidence both quantitative and qualitative has been accumulating that suggests Bislama is indeed gaining ground at the expense of Vanuatu’s Indigenous languages. In a targeted review of this evidence, this article brings together and assesses the insights of linguists, ethnographers, and others on the causal mechanisms that explain an ongoing shift towards Bislama. It thereby provides both a critical analysis of the current state of knowledge and a provisional causal framework for understanding current threats, predicting future threats and, potentially, intervening to prevent future threats. Language endangerment and extinction is a global issue with devastating implications for communities worldwide – one which Vanuatu, the world’s most linguistically diverse country, has thus far remained resilient in the face of. However, this review of the available evidence warns that Bislama will continue to disrupt intergenerational transmission of Indigenous languages unless a suite of inter-related mechanisms can be counteracted.
How does scientific research generate impact beyond academia? Cross-disciplinary comparison based on REF impact cases
Authors: Cao Zhe , Zhang Lin , Wang Zelin , Li Chen , Sivertsen Gunnar
Published: October 2024

The impact of scientific research beyond academia is receiving increasing attention from both scientists and the broader community. However, the mechanisms driving this impact remain unclear. This study systematically reviews existing theoretical models and seeks empirical evidence from the REF impact case data. Through grounded coding analysis of 200 cases across four units of assessment, six stages of research generating impact were identified – problem identification, research conduct, output production, output utilization, impact formation, and multi-stakeholder interaction. These stages encompass 10 key elements and 43 corresponding sub-categories, forming a novel theoretical model. Comparative analysis revealed that, while the generation of research impact beyond academia generally follows a similar logic across disciplines, obvious differences exist in motivation, research approach, forms of outputs, types of impacts, etc. This study further provides four typical cases for illustration. Our aim is to enhance the understanding of impact generation processes, promote the societal benefits of scientific research, and provide a basis for research managers to assess scientific contributions according to their distinct characteristics.
The Development of Non-Formal Learning Organization Skills in Preservice Math Teachers
Authors: Tural Sönmez Melike
Published: October 2024

Although the effects of out-of-school learning on students' learning have attracted significant attention among education researchers in science and social sciences, little is known about the development of pre-service elementary mathematics teachers' skills in utilizing out-of-school learning in mathematics lessons. The aim of this research is to investigate the impact of activities conducted within the scope of the out-of-school learning environments in mathematics education on pre-service elementary mathematics teachers' skills in organizing non-formal learning. The study utilized a sequential explanatory design, which is a mixed-method approach. The quantitative part of the research employed a "single-group pretest-posttest design without a control group" from experimental designs. This study involved 35 third-year teacher candidates enrolled in the Primary Education in Math Program (PREDMAP) at a state university located near Ankara, the capital city of Turkey. The data collection instrument used in the study was the Out-of-School Learning Regulation Scale (OOSLRS). Additionally, teacher candidates were asked to write reflective essays about their thoughts on the program at the end of the study. The analyses revealed that prior to the program, pre-service math teachers had the highest scores in the knowledge dimension and the lowest scores in the implementation dimension of organizing out-of-school learning. Significant differences were found in the pretest scores of preservice math teachers only in the knowledge dimension based on their previous experiences in organized out-of-school learning environments during their educational lives. Significant improvements favoring the post-test application were observed across all dimensions between pretest and posttest scores. Data from reflective essays written by the preservice math teachers indicated their emphasis on active participation and included suggestions particularly in the implementation dimension.
Picture Your Science Educators: Through the Eyes of the Student Teachers
Authors: Baran Medine , Baran Mukadder
Published: October 2024

This study was aimed to examine and compare the opinions of science teachers studying at undergraduate and master levels in Norway and Turkey towards their instructors. 22 students studying in science fields at a state university in Norway and 28 students studying in science fields at a state university in Turkey participated in the research. The students participating in the research were selected on the basis of a easily accessible sample. Research data was collected using a structured interview form consisting of 5 open-ended questions that questioned students' opinions about the instructors. The data obtained at the end of the research was analyzed using content analysis and descriptive analysis methods. Considering the findings, the themes of student opinions were obtained: 21st century skills of the science instructors, methods and techniques they use in the classroom, the effects of the science instructors on themselves, what I would do if I were a science educator, and role modeling. While some of the participating students in Turkey found the lecturers inadequate in terms of 21st Century skills, most of the students in Norway found the lecturers sufficient. While student teachers in Turkey emphasized that science instructors ' interaction and communication with students and a strong academic infrastructure are important, participants in Norway pointed out that science instructors have positive effects that contribute to being a good teacher. However, participating students in both groups stated that more traditional teaching methods were used in the classroom. It was determined that students had negative opinions as well as positive opinions. The two most important components of the university learning environment that are meaningful to each other are students and science instructors. Therefore, it is thought that more qualified teaching activities will be realized if science instructors care about what students think about them

Authors: Molongwane Tonny Chidi , Ngobeni Elias Tsakane , Sepeng Percy
Published: October 2024

Progression is good for promoting learners from one stage to another and for career development. Secondary schools in Limpopo Province, South Africa, use progression. The study investigated the impact of progression on Grade 12 learners’ performance in Capricorn District, South Africa. A phenomenological design was employed to identify the impact of the progression of learners. Study participants were purposively selected from three schools because they had valuable information regarding the impact of learners’ progression on learning outcomes in Capricorn District. Data were collected through semi-structured interviews, document analysis and focus group interviews. Data were analysed thematically. The results show that stakeholders' perceptions suggest that the progression of learners resulted in poor performance in Grade 12 final examinations in the study area. Teachers' lack of skills in dealing with academic challenges led to low pass rates. The findings have implications for the implementation of progression policies in secondary schools

Authors: Nahwera Loyce , Kiptolo Boit Edwin , Nsibambi Constance Adron Nakayiza , Maghanga Mshilla , Wachira Lucy-joy
Published: October 2024

Hypertension which impacts over 1.5 billion people globally is a crucial health challenge accountable for more than 10.8 million early deaths yearly. Our study used an experimental design to investigate the effects of aerobic dance programme on diastolic blood pressure levels in stage one hypertensive adults over a 12-week period. The study participants were randomly allocated into either the experimental or control groups. Diastolic blood pressure measurements were collected using a mercury sphygmomanometer at baseline and post programme. The 12-week aerobic dance programme entailed three 45-minute sessions per week, at a moderate intensity. The paired samples t-test was used to compare mean differences within the groups with the significance level set at P<0.05. Findings showed that mean diastolic blood pressure of participants in the experimental group was 93.11±3.708 mmHg and 91.61±4.340 mmHg at baseline and post programme while that of the control group was 92.39±3.032 mmHg and 92.06±6.655 mmHg respectively. This implies that there was a marginal reduction of -1.50 mmHg in diastolic blood pressure of the experimental group while the control group remained relatively constant at -0.33mmHg after the programme. Paired sample t-test results confirmed no statistically significant effects (t(17)=1.129, p=.275) for experimental group as well as the control group (t(17)=.257, p=.800). This study concluded that participating in an aerobic dance programme at a moderate intensity for 12 weeks did not statistically significantly reduce diastolic blood pressure of adults with stage one hypertension. Future studies on this population should investigate additional influencing factors and varying training intensity to assess any other effects.

Authors: Sarwar Lubna Ghulam , Azhar Mian M , Baig Mirza Shahid Rizwan
Published: October 2024

This study examines how judicial activism impacts governance in Pakistan after the lawyer's movement with a focus on its effect on human rights, the rule of law, and accountability. The study uses mixed techniques to examine Supreme Court decisions and interventions that demonstrate the judiciary's role in protecting civil liberties and checking executive powers. Apex Court's activism on extrajudicial killings forced disappearances, and gender discrimination has advanced human rights, according to the findings. The research also shows how the judiciary has strengthened the rule of law by upholding and enforcing legal principles fairly, boosting public faith in legal institutions. The research also notes that alleged judicial overreach has caused problems between the legislative and executive branches due to the courts' wide interpretations of their authority. This detailed analysis highlights the delicate balance between judicial interventions and democratic government.
Effect of temperature and adhesive defect on repaired structure using composite patch
Authors: Abdulla Mohammed , Hrairi Meftah , Shaikh Abdul Aabid , Abdullah Nur Azam
Published: October 2024

In structural engineering, composite patch repairs are widely used to address cracked structures. However, their behavior under thermo-mechanical loading remains complex and less understood. This study examines the repair of a center-cracked plate subjected to both mechanical and thermo-mechanical environments, using finite element analysis in ANSYS. The repair effectiveness is evaluated using the Stress Intensity Factor (SIF) at the crack tip. Findings reveal that increased temperature substantially elevates SIF values. Boron/epoxy patches are most effective under mechanical loading, yielding the lowest SIF, while graphite/epoxy patches excel under thermo-mechanical loading due to their lower Coefficient of Thermal Expansion (CTE). Patch thickness influences SIF differently based on loading conditions; thicker patches decrease SIF under mechanical loading but increase it under thermo-mechanical loading. Furthermore, adhesive defects, particularly at the crack tip, markedly increase the risk of adhesive failure, especially under thermo-mechanical conditions. This research underscores the significant impact of temperature variations on the efficiency of structural repairs, contributing to a deeper understanding of composite patch repair performance in cracked structures.
Detection and Correction of Likert Scale Multiplicative Response-Style Bias
Authors: Oldenburg Reinhard
Published: October 2024

Individuals may differ in their tendency to fully use the range of a Likert scale. Such individual response styles may have an effect on estimates of correlations. It is shown with simulated data that a relatively simple nonlinear latent model can be used to detect and correct (to some extent) for the bias introduced by differences in multiplicative response styles. A real-world dataset is examined to show that the effect may occur in reality and may lead to biased conclusions.
Philosophical Aspects of Time in Modern Physics
Authors: Driessen Alfred
Published: October 2024

In classical physics, the concept of time appeared to be well-understood. With space, it provided a kind of stage where the events followed each other in an orderly way. The introduction of relativity and quantum mechanics profoundly changed this intuitive view. To address these challenges, the Aristotelian vision of time and the now is a promising starting point. His approach is compatible with the absence of absolute time and time's granularity, required by relativity and quantum mechanics, respectively. Several issues, like Einstein’s point coincidence argument and Wheeler's delayed choice experiment, enter the discussion. The Aristotelian approach appears to lead to a novel understanding of time in modern physics.
Risks of Coronavirus Infectious Disease 19 (SARS-CoV-2) in Companion Animals
Authors: AL-Farwachi Maab Ibrahim , Albadrani Basima Abdulfatah , AL-Obadi Qaes Talb , Daher Hassan Saddam , Iqbal Muhammad Naeem
Published: October 2024

The epidemiological situation of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in humans and animals is continually evolving. Given the probable animal origin of SARS-CoV-2 and the recent case reports in pets, especially cats and dogs, and their close contact with humans, it is critical to comprehend how sensitive SARS-CoV-2 is to humans and vice versa in order to control the coronavirus infectious disease 19 (COVID-19) pandemic. The most susceptible companion animals to contract SARS-CoV-2 infection include cats, ferrets, and hamsters. The virus SARS-CoV-2 that is carried from pets to humans is generally thought to have little to no effect on the viral transmission across the broader community, and there is little evidence of mutations. Thus, there is no requisite for specialized surveillance programmes for SARS-CoV-2 infection in pets; in most cases, testing should only be done on pet owners or veterinarians who interact with these animals. It is recommended to properly dispose of human waste in order to lower the probability of SARS-CoV-2 spreading to animals. Additionally, it is best to avoid contact with pets, particularly if they are ill or deceased. In addition to evaluating animals exhibiting clinical indications, monitoring is advised for household pets.
A Simplified Model for Propeller Thrust in Oblique Flow
Authors: Patience Christian , Nahon Meyer
Published: October 2024

New aircraft architectures are being proposed for unmanned aerial vehicles and air taxis, which include tilt-able motor and propellers. These propulsive units operate with a propeller axis at an angle oblique to the flight direction, and thus it is important to understand and model how thrust is produced by a propeller operating under these conditions. Propellers in oblique flow have been modeled using Blade Element Momentum Theory coupled to an inflow model, and the Vortex Lattice Method. In the present work, we develop a much simpler approach that neglects the crossflow component of the incoming air velocity. An advance ratio is developed based on the parallel inflow component, and is coupled to existing propeller data collected in axial flow conditions. The proposed model is evaluated using existing experimental data collected under oblique flow conditions, and is predicts thrust to within \(5\,\%\) of experimental values for most conditions. The greatest discrepancy between the model and experiments occurs in the pure crossflow case, which is of lesser importance in the application to unmanned aerial vehicles and air taxis.
Informe de ocjetivos de desarrollo sostenibles de la Universidad Autónoma de Chile (2019-2023)

Published: October 2024

Una de las iniciativas más influyentes en los últimos años surge con la declaración de los Objetivos de Desarrollo Sostenible (ODS) por parte de la Organización de las Naciones Unidas (Naciones Unidas, 2015). Estos objetivos fijan 17 metas (ver Figura 1) que deben ser conseguidos por las naciones antes de 2030 (Naciones Unidas, 2017). Actualmente la producción científica en torno a los ODS es amplia y las principales fuentes de información asocian cada documento a uno o varios ODS, mientras que las instituciones en sus CRIS igualmente le asignan los ODS a las contribuciones de la universidad, lo cual valida la relevancia del tema en los entornos de investigación. Con respecto a la investigación de corte bibliométrico en los que se analiza la producción en los distintos ODS es igualmente amplia. En el contexto regional se ha comparado la producción de los países hispanoamericanos y su producción científica registrada en Scopus (Elsevier) sobre los Objetivos de Desarrollo Sostenible (ODS) (Arroyave et al., 2024), producción científica relacionado con la Educación de Calidad (ODS 4) (Estrada-Molina et al., 2024), la contribución de las universidades españolas a los ODS (Repiso et al., 2023), los cuales representan un importante punto de partida con relación a la mirada bibliométrica necesaria para comprender los efectos e importancia de los ODS en la región. Por tanto, evaluar mediante indicadores bibliométricos, la cobertura que se le ha dado a los ODS en las universidades es clave no solo para conocer cómo se está investigando desde lo cuantitativo, sino también otras variables como el impacto medido en citas e incluso la repercusión de esa investigación en fuentes no tradicionales.

Published: October 2024

Background and Objectives: One of the foundations of the health system are nurses. Migration is one of the factors of reducing and losing this valuable capital. Methods: In this systematic review study, PubMed, Scopus, Web of Science, SID, Magiran and Google Scholar databases were searched without time limit and based on the Prisma method, and in order to evaluate the quality of the articles, critical evaluation checklists of the Joanna Briggs Institute (JBI) were used. Results: First, 265 articles were extracted. After screening and removing duplicate articles, unrelated, without complete text, the qualitative evaluation stage was performed, and finally 17 articles were included in the study. No intervention was reported in the articles and no study prioritized the identified effective factors. The causes affecting migration were classified into two main categories: Causes related to the country of origin (push factors) and causes related to the destination country (pull factors). The factors in the countries of origin and destination were counted in three areas: individual factors, social factors and cultural factors. Income, job position, job security, continuing education facilities and educational technology, team relations and facilities in the work environment and family status were identified as the most important factors affecting migration. Conclusion: Nurses and especially young nurses from third world countries had a high desire to immigrate. Considering the multi-dimensional causes affecting the migration of nurses, in order to manage this phenomenon effectively, special attention and structural reforms in the social, cultural, political and economic dimensions are needed

Authors: Astarkhanova T. S. , Alibalaev D. A. , Alibalayeva L. I. , Abasova T. I.
Published: October 2024

Sanitary monitoring of spring wheat agrocenosis in the zone of unstable moisture was carried out to determine the degree of development and prevalence of diseases. The fungicidal activity and effectiveness of seed protectants of various classes against seed infection on spring wheat variety Yasenka have been studied. The results of the research established the effectiveness of the disinfectant DVD Chance, KS, corresponding to 85.7% relative to the effectiveness of the standard Polaris, ME Eco Plus (100 g/l prochloraz + 25 g/l imazalil + 15 g/l tebuconazole) (84.6%). An increase of 15–20% in damage to spring wheat plants by root and basal rot caused by fungi of the genus Fusarium in the “tillering” phase and its dependence on the climatic conditions of the growing season was established.

By the “flag leaf” phase, the prevalence of root and basal rot caused by fungi of the genus Fusarium increased to 20,5%, and the degree of development — to 7–9%.

Evaluation of the effect of the fungicide DVD Chance, KS (30 g/l difenoconazole + 6.3 g/l cyproconazole) by pre-sowing treatment of spring wheat grain of the Yasenka variety established the effectiveness of the drug at a consumption rate of 1.0 l/t against molding of seeds, corresponding to 85.6% , in the reference variant the indicator is 84.6%, with the development of the disease in the control — 34.5%. By harvest, the effectiveness of the drug remained and reached 79.2%, in the standard — 78.3% with the development of the disease 43.7%. Research contributes to the expansion of the range of fungicides for treating grain crops, the development of regulations for use and the possibility of recommending them for registration tests for further inclusion in the State Catalog of those approved for use.

The work was carried out in the technology of yield planning 40 c/ha, with the introduction of liquid complex fertilizers (HCS NР 11:37) before sowing in the amount of 50, 100 and 150 l/ha per depth 5, 10 and 15 cm. In the experiment, the traditional technology of preparing the soil for salting with the regulation of the number of the weed component by Express Sun technology was used. Due to the increased growth energy of the hybrids under consideration, the height of plants varies according to the phases of development and maturation in the studied variants reached 177–191 cm, which is 4.7–6.5% higher than the control values. The mass of plants in the sunflower agrocenosis increased in the Sumiko hybrid by 13.2%, P63LE10 by 11.1%, Elion by 12.5%. The plants of the hybrid Elion accumulate more dry matter in the aboveground mass. The use of HCS at a maximum dose of 150 l/ha when applied to a depth of 15 cm contributed to an increase in the accumulation of dry matter by the maturation phase in the plant biomass of the Sumiko hybrid by 304.3 g/m², the P63LE10 hybrid by 177.7 g/m², the Elion hybrid by 354.0 g/m², or, respectively, by 34.7%, 17.2% and 33.7% relative to the control.

Relevance. The creation of high-quality oilseed flax seeds using new plant breeding methods is an imperative principle with the advent of better crop seed production. Current methods for creating such seeds continue to be complicated and laborious. In this regard, the development of more advanced methods for obtaining renewed seeds with a high level of manifestation of sowing, various types and morphophysiological properties is relevant and has practical importance.

Methods. The experiments were carried out in accordance with the methods of planting, conducting field experiments with flax, and methodological recommendations for seed production of oil flax. The assessment of sowing quality and seed material was carried out in accordance with the current certification system , varietal quality — by the soil control method.

Results. The high efficiency of creating updated oilseed flax seeds using the method of plant selection during the growing season — from the beginning to the end of full flowering, which allowed for a significant increase in their yield to 61.5%, compared with the control. Selection of plants in the interval from the beginning to the end of full flowering ensured the preservation of the sowing qualities of the created seeds at the control level — selection according to the current method, as well as increasing the uniformity of indicators of the morphophysiological properties of seeds, including the uniformity of seed sprouts along the length by 4.6%. The selection method with the removal of plants atypical in morphological charakteristics compared with the control allowed to increase the yield of updated oilseed flax seeds by 29.7%, improve their morphophysiological properties. The varietal quality of the updated seed material for all methods of its creation was characterized by the absence of atypical seeds in color and minor differences between the options in the uniformity of varietal characteristics.
Productivity and amarketable gualities of apple tree fruits of the Golden Delicious variety on low growing rootstocks depending on pruning

Published: October 2024

One of the main agrotechnical activities carried out in the garden is tree pruning. When studying the variety-double combinations of apple trees in certain environmental conditions, it is necessary to take into account the strength of growth, the density of fouling, the type of branching, the structure of fruit formations, which depends on the varietal characteristics and technologies of growing plantations.

The author presents the results of studying the parameters of the influence of the degree of pruning of Golden Delicious apple trees grafted on low-growing rootstocks SK-7 and M-9, depending on the rootstock, on growth processes, productivity and marketable qualities of apple fruits. The reaction of plantings to pruning was determined depending on the biological characteristics of the variety and on the degree of branch removal and their orientation. With an increase in the intensity of pruning, the leaf surface area per fruit on the rootstock SK-7 was 180–750 cm², on the rootstock M-9 — 172–619 cm², respectively. The yield of apple trees from one tree on the rootstock SK-7 was 13.2 kg with a minimum shape, 11.4 kg with an average, 10.5 kg with a maximum, and 11.4 kg, 9.5 kg and 7.7 kg on the rootstock M-9, respectively. The average weight of fruits grafted on the rootstock SK-7 increased by 1.9 times, and on the rootstock M-9 — by 1.3 times.

It was noted that the life cycles of trees on the low-growing dwarf rootstock SK-7 were 10–12% higher than on the rootstock M-9.

Relevance. The creation of a botanical collection of the lotus family made it possible to study the biology and adaptive features of a rare relict species of Nelumbo nucifera and its variety in the conditions of the Stavropol Upland.

Methods. The main phases of development (the beginning of growth, budding, flowering) were recorded. Statistical processing was carried out by the method of variance analysis according to G.N. Zaitsev.

Results. In 2010, Nelumbo nucifera seeds were purchased from the Volga River Delta and planted in a 100-liter container, which was located in a closed ground. From 2010 to 2014, the plant vegetated every year from the second decade of January to November, in November, vegetation was artificially stopped. With such agricultural techniques, the plant had no flowering and fruiting phases. In June 2014, rhizomes were planted and lotus seeds were sown in a pond made of butyl rubber film. In 2017, the first flowering was observed. During the study period, the plants did not reach natural indicators, on average, the diameter of the leaves is less by 18.5 ± 1.6 cm, the flowers are 2 ± 0.1 cm, the height is 1.0–1.5 m. The duration of flowering is 57 ± 4 days, which corresponds to the natural conditions of lotus growth from mid-July to early September. During the years of research, 495 seeds were obtained. Under the influence of abiotic factors, the nut-bearing lotus lives up to 8 years in the botanical garden. Nelumbo nucifera Betsy grows intensively, flowering occurred in the third year after sowing, leaf diameter 57 ± 3 cm, height above the water surface 78 ± 7 cm, flowering duration 73 ± 7 days, which is longer than that of the nut-bearing lotus, full-fledged seeds are formed.

Relevance. The article presents data on the toxicological assessment of the safety of the specific immunobiostimulant of antigen-directed action “Transfer Factor” in a form ready for intramuscular administration and obtained from the blood of hyperimmunized donors on laboratory animals in an acute experiment.

Methods. The object of the study was the finished form of “Transfer Factor”, the acute toxicity of which was determined in models on laboratory animals (nonlinear mice, nonlinear rats).

Results. It was found that after administration of the drug to mice intramuscularly (0.25 ml/head) and intraperitoneally (0.5 ml/head), to rats intramuscularly (2.5 ml/head) and intraperitoneally (2.5 ml/head), muscle tremor is observed, disappearing after 15–20 minutes. Intraperitoneal administration of the drug to mice and rats in dosages of 0.75 ml/head and 3.75 ml/head, respectively, determines the presence of tremor lasting 40 minutes. During the 14-day observation period, the body weight of mice and rats increases by 10.15-14.25 and 11.84-17.67%. Autopsy of animals does not reveal visible changes in the location of organs and fluid in the abdominal and pleural cavities. However, some pathological changes in color, consistency and size are found in the lungs, heart, spleen and liver with intramuscular administration of Transfer Factor to mice and rats at a dose of 0.25 ml/head and 2.5 ml/head, intraperitoneal administration to mice at a dose of 0.5 ml/head and 0.75 ml/head and to rats 2.5 ml/head and 3.75 ml/head. Based on the totality of changes in the vital signs of laboratory animals, body weight and macroscopic characteristics of internal organs according to GOST 12.1.007-76, the drug “Transfer Factor” can be classified as hazard class IV “Low-hazard substances”.
