Биологические особенности ели сибирской и сосны кедровой сибирской определяют возможность их эффективного использования в условиях Западной Сибири. На территории УПХ «Сад Мичуринцев» Новосибирска изучена вертикально-фракционная структура фитомассы посадочного материала этих пород и развитие открытой и закрытой корневой системы. Проанализированы биометрические показатели саженцев с открытой и закрытой корневой системой. Установлено, что способ выращивания оказывает влияние на формирование подземной и надземной части посадочного материала. Так, у саженцев исследуемых пород с открытой корневой системой наблюдаются более высокие показатели прироста в высоту, чем у саженцев с закрытой корневой системой. Сделан вывод о том, что в прирост осевого побега у посадочного материала хвойных пород наибольший вклад вносит вид корневой системы – 64 %.
The biological features of Siberian spruce and Siberian stone pine determine the possibility of their effective use in the conditions of Western Siberia. The vertical-fractional structure of the phytomass of the planting material of these species and the development of an open and closed root system were studied on the territory of the UPH "Garden Michurintsev" of Novosibirsk. The biometric indicators of seedlings with open and closed root systems were analyzed. It has been established that the cultivation method has an impact on the formation of the underground and above-ground parts of the planting material. Thus, in seedlings of the studied species with an open root system, higher rates of growth in height are observed than in seedlings with a closed root system. It was concluded that the type of root system makes the greatest contribution to the growth of the axial shoot in the planting material of coniferous species – 64%.

Представлены результаты многолетних работ по переформированию мягколиственных малоценных насаждений в кедровые (сосна сибирская кедровая) на территории Березовско-Лавровской лесной дачи Томской обл. Исследования имеют значение для планирования систем ведения лесного хозяйства в орехово-промысловых зонах, примыкающих к населенным пунктам. Результаты показывают, что при выполнении мероприятий по переформированию мягколиственных насаждений в кедровые необходимо применять комплексный подход, сочетающий в себе уход за сформированными насаждениями кедра и культурами кедра, а также организацию системы противопожарного обустройства.
The article presents materials of long-term work on converting soft-leaved low-value forests into Siberian pine stands on the Berezovsko-Lavrovskaya dacha’s territory in the Tomsk region. The study has a great potential for planning forestry systems in Siberian pine’ seeds (nuts) producing areas adjacent to populated areas. The results show that when implementing measures of transformation soft-leaved forests into pine plantations, it is necessary to apply an integrated approach combining the care of formed Siberian pine plantations and its crops, and the fire-fighting system organization.

Рассмотрены особенности формирования древесины ствола и индекс флуктуирующей асимметрии (ИФА) хвои 50-летних деревьев сосны обыкновенной, произрастающих в зоне крайне высокой степени радиоактивного загрязнения (>40 Ки/км2). Анализ средних приростов за период роста деревьев с 1962 по 2013 г. показал, что выбросы радиоактивных веществ в результате катастрофы на ЧАЭС в 1986 г. не оказали заметного влияния на развитие ксилемы исследованных деревьев, что может свидетельствовать об их меньшей чувствительности в результате пережитого более сильного стрессового воздействия климатических факторов 1968–1969 гг. Предполагаем, что это воздействие могло послужить причиной невысоких значений ИФА хвои сосны обыкновенной данной популяции.
The features of trunk wood formation and the index of fluctuating asymmetry (ELISA) of needles of 50-year-old Scots pine trees growing in an area with extremely high levels of radioactive contamination (>40 Ki/km2) are considered. An analysis of the average growth over the period of tree growth from 1962 to 2013 showed that the emissions of radioactive substances as a result of the Chernobyl disaster in 1986 did not have a noticeable effect on the development of the xylem of the studied trees, which may indicate their lower sensitivity as a result of the more severe stress of climatic factors of 1968–1969, we assume that this effect it could be the reason for the low values of the IFA of the needles of the common pine of this population.

Abstract

OBJECTIVE
To investigate whether liver compression (LC) could increase stroke volume (SV) by more than 15% in healthy, anesthetized dogs with hypovolemia and suggest LC as a novel method to evaluate fluid responsiveness.

ANIMALS
6 healthy Beagles.

METHODS
This prospective, nonrandomized experimental study was conducted from November 2023 to February 2024. The dogs were anesthetized with isoflurane and mechanically ventilated under neuromuscular blockade. After instrumentation, the dogs underwent the following 4 experimental stages in a sequential, nonrandomized manner: stage 1, baseline; stage 2, 30% withdrawal of circulating blood volume; stage 3, 50% infusion of the collected blood; and stage 4, the remaining 50% infusion of the collected blood. At each stage, SV via pulmonary artery thermodilution and hemodynamic variables were measured before, during, and after the LC.

RESULTS
In stage 2, LC significantly increased mean SV by 30%, from 6.9 to 9 mL/beat. Simultaneously, LC significantly increased mean arterial pressure by 11 mm Hg and mean central venous pressure by 2 mm Hg, while pulse pressure variation significantly decreased from 28% to 22%. In stages 1, 3, and 4, LC did not significantly change mean SV, mean arterial pressure, and pulse pressure variation; however, mean central venous pressure significantly increased during stage 3.

CLINICAL RELEVANCE
This study demonstrates that LC at 22 mm Hg for 1 minute could increase SV more than 15% in anesthetized, hypovolemic dogs and LC could be used as a novel method to evaluate fluid responsiveness.

Abstract

OBJECTIVE
To evaluate the effects of topical naltrexone on wound healing in freshwater fish.

ANIMALS
25 blackbelt cichlids (Vieja maculicauda).

METHODS
A randomized, controlled, experimental trial was performed, with each individual serving as its own control. Bilateral 6-mm periepaxial cutaneous wounds were created in the body-wall skin of each fish under anesthesia. Three treatment groups were as follows: topical 0.04% naltrexone in administration vehicle (iLEX ointment; iLEX Health Products) at day 0 only (n = 10), topical 0.04% naltrexone in iLEX every 72 to 96 hours (n = 10), or iLEX only every 72 to 96 hours (n = 5) for 10 total treatments. The contralateral wound was left untreated as a control. Fish were maintained in a common enclosure at 24.7 to 25.4 °C for 35 days. Macroscopic wound assessment and image collection were performed every 72 to 96 hours. On day 35, fish were humanely euthanized, and skin samples were collected for histopathology.

RESULTS
Time to complete visual resolution of wound healing was faster (P = .002) in wounds treated every 72 to 96 hours with topical 0.04% naltrexone in iLEX (day 19.4) compared to untreated wounds (day 23.3). An interaction between treatment and day was observed (P = .002), with fish treated with 0.04% naltrexone in iLEX every 72 to 96 hours having reduced (P < .05) wound area compared to both controls and fish treated with topical 0.04% naltrexone in iLEX once. No significant differences were noted in histologic sections of wound sites examined at day 35.

CLINICAL RELEVANCE
Fish improved earlier postsurgery and time to complete wound resolution was faster in wounds treated with topical 0.04% naltrexone in iLEX every 72 to 96 hours.

Published: July 2024

Abstract

OBJECTIVE
The objective of this study was to provide orientation values for fructosamine in adult llamas and to characterize relationships with other laboratory and clinical parameters.

ANIMALS
Data from 22 healthy adult llamas of both sexes.

METHODS
A retrospective study was conducted with the findings of a veterinary herd visit from August 2022. Fructosamine measured from plasma samples was characterized, and its relationships with clinical and laboratory diagnostic data was analyzed using descriptive statistics and correlation analysis.

RESULTS
Fructosamine was 311 ± 34 µmol/L (mean ± SD), with a range of 254.8 to 409.2 µmol/L. Males showed significantly higher plasma fructosamine levels than females (P < .05). Plasma fructosamine revealed significant positive correlations with glucose, total protein, and albumin and also with PCV, hemoglobin, calcium, sodium, and selenium. Female llamas revealed further positive correlations with body condition scoring.

CLINICAL RELEVANCE
The results of this study can be used as orientation values for fructosamine in llamas. Fructosamine is used to distinguish acute hyperglycemia caused by stress from chronic hyperglycemia in other species, which might be caused by disorders of the glucose metabolism.
Causes, treatment, and outcome of hyphema, fibrin, and vitreal hemorrhage in horses: 219 cases (2012–2023)
Authors: Gould Jonathan , Wells Mary , de Linde Henriksen Michala , Gilger Brian C. 
Published: July 2024

Abstract

OBJECTIVE
To determine the causes, time to resolution, effect of therapeutics, and ocular sequelae of hyphema, fibrin, and/or vitreal hemorrhage in horses.

ANIMALS
225 horses (219 eyes) who were diagnosed with hyphema, fibrin, and/or vitreal hemorrhage.

METHODS
Records were retrospectively reviewed for the horses. Signalment, ophthalmic examination findings, causes, treatments, and outcomes were evaluated.

RESULTS
Common causes of intraocular fibrin or hemorrhage were equine recurrent uveitis (42/219 horses), corneal stromal abscess (32/219 horses), corneal stromal ulcer (25/219 horses), and trauma (21/219 horses). Eyes with fibrin that were treated with intracameral tissue plasminogen activator (TPA; n = 18 eyes) had significantly lower days to resolution (8.9 ± 12.6 days) compared to eyes not treated with TPA (28.3 ± 46.7 days). Ocular sequelae in horses with fibrin, such as cataracts (18/120 eyes), synechiae (11/120 eyes), and vision loss (17/120 eyes), were significantly less common in eyes treated with TPA. Sequelae in eyes with hyphema included cataracts (9/36 eyes), synechiae (6/36 eyes), and vision loss (5/36 eyes). Although 41 horses had an enucleation at presentation because of severe disease, 14/144 (< 10%) of horses with follow-up required an enucleation.

CLINICAL RELEVANCE
The presence of blood products in the eyes of horses suggests severe ocular disease, but if the eye is not enucleated at presentation, the prognosis is good for maintaining the eye. Also, the use of intracameral TPA in horses with anterior chamber fibrin but not those with hyphema, results in less adverse ocular sequelae.

Published: July 2024

Abstract
Based on the coupled communication of smart elderly care and traditional Chinese culture, this paper proposes four paths of coupled communication, including in-depth communication, innovative cultural forms of communication, precise communication, and promotion of coupled development. Two systematic index systems have been constructed to disseminate traditional Chinese culture and develop smart culture and pension. The data is standardized using principal component analysis to establish the correlation coefficient matrix. The coordination index between the two subsystems is calculated, and the coordination model of the two is created based on the concepts of coordination coefficient and coefficient of variation. The subject area, Province S, is in the third stage of the coupled coordinated development during 2010-2023, with traditional culture dissemination and smart elderly care services coming to a high level, and is in a good development level during 2016-2023, with a coupled coordination degree of 8 or more. Using the VAR model, the effect of coupling development on the quality of life of elderly individuals is analyzed. Impulse response analysis of LNCCD and LNQOE: after LNCCD receives a positive shock, LNQOE shows a sharp shock effect. At this time, the response value is 0.07021, which plays a large positive effect, and then enters into a smooth development. The traditional Chinese culture dissemination and the wisdom culture of old age are in the stage of coupled development.

Published: July 2024

Abstract
This paper takes three colleges and universities in a province as an example, designs relevant questionnaires and distributes them, and analyzes the collected data by using statistical methods such as independent samples t-test and ANOVA one-way ANOVA. The paper analyzes the data collected using statistical methods such as independent sample T-tests and ANOVA to infer the overall situation of the current level of emotional identification with Marxist theory among Chinese college students. The data was examined in detail to determine the variations in the emotional recognition of Marxist theory among college students based on their gender, ethnicity, and professional classification. The results show that more than 50% of college students understand Marxism and strongly identify with it. The overall mean score of affective identification is 35.324, which is a good status for identification. In terms of different genders, the P-values of value identity, knowledge identity, social identity, and behavioral identity are less than 0.1, and there are significant differences. Emotional identity does not have significant differences in different ethnicities (P = 0.382 > 0.05) and different majors (P = 0.426 > 0.05).

Published: July 2024

Abstract
Cultivating innovative talents is an important goal of the talent cultivation strategy in the new era, and ideological and political education is an indispensable part of cultivating a correct outlook on life and the spirit of innovation. In order to fully leverage the supporting role of ideological and political education in cultivating innovative talents, this paper proposes an enhanced collaborative filtering algorithm and content recommendation algorithm. The traditional Civic and Political learning evaluation algorithm is improved by considering the forgetting factor and introducing disciplinary abilities and sequence dependence. The results of the experimental analysis point out that the average grade improvement of the seven Civics and Politics knowledge points of the students in the experimental class reaches 10.3%, the mean value of the four innovation dimensions reaches 14.95 points, and the average agreement rate between the self-assessment results of the learning effect and the results of the evaluation model is 90%. It shows that the optimized Civics personalized learning and evaluation method, based on this paper, has positive effects.

Published: July 2024

Abstract
In modern society, innovation and entrepreneurship education have gradually transcended the traditional paradigm, intertwined with the concept of commonwealth, and constructed a new picture of vitality and social sentiment. In terms of research ideas, this paper extracts value-shaping elements, service learning elements, social creation faculty elements, social creation curriculum elements, organizational leadership elements, interest group elements, and social creation practical elements as the elements of entrepreneurial competence cultivation of college students according to their growth pattern, the entrepreneurial environment they have, and entrepreneurial resources they possess. We obtained the four crucial factors for individual, group, school, and social levels through micro-level analysis. We constructed the model for cultivating entrepreneurial competence in college students with the support of seven elements and four hierarchical factors. In the end, the cultivation model was analyzed using the PLS-SEM model. It has been verified that 11 out of the 13 hypotheses proposed in this paper were supported through testing. 11 cultivation paths that passed the significance test were found after further analysis. The most significant path is the SF->IE->PO path under the policy anchoring force, with effect sizes and t-statistics of 0.325 and 7.494, respectively. In this way, we have refined the methodology of cultivating co-enrichment and entrepreneurship skills among university students.

Abstract
Colleges and universities have a singular and one-sided understanding of physical education teaching, and teachers, staff, and students remain in the simple teaching activities of improving students’ physical fitness and learning sports skills. Aiming at such problems, according to the feasibility of integrating curriculum ideology into physical education teaching in colleges and universities, the physical education teaching based on curriculum ideology in the field of artificial intelligence is designed, and the implementation and training path of this teaching mode is pointed out in detail. On the basis of the principle of the construction of the evaluation index system, the evaluation indexes are screened and corrected through the combination of searching for literature and expert guidance, and the evaluation index system of physical education teaching effect based on the course of thinking and politics is finally determined. Substitute the evaluation index data into the corresponding judgment matrix, use the hierarchical analysis algorithm to conduct a consistency test on the judgment matrix, derive the evaluation index weight value, and complete the construction of the teaching evaluation model. The constructed evaluation model is used to evaluate and analyze the physical education teaching effect of the pooled course Civics. The data show that the weight of C1 is 0.351, while the weight value of D1 is 0.120, and the other is the same. The final result of the comprehensive evaluation and analysis of physical education teaching by integrating curriculum ideology and politics is 3.3573, which indicates that the path of integrating curriculum ideology and politics into physical education teaching in colleges and universities mentioned above can effectively promote the overall development of students’ morality, intelligence, physical fitness, aesthetics, and labor. This study not only provides direction for ideological and political work but also provides theoretical support for physical education in schools.

Published: July 2024

Abstract
It is possible to use RS, GIS, GPS, and other technologies to collect, manage, analyze, and use tourism geographic information in a system that is based on a tourism geographic information database. These technologies can be used to manage, evaluate, predict, and do other things with tourism geographic information. To integrate ideological and political education elements into the tourism geographic information system course and to establish a new system of ideological and political education and professional courses combined to educate people. Researchers explore the role of teaching practice in enhancing professional performance and ideological and political literacy through controlled experiments and questionnaires. The results indicate that the weight value in the middle of the class, at 0.61, is the most significant component of the teaching link due to the weight setting. The experimental class’s tourism geographic resources test score averaged 86.34, 5.51 points higher than the control class’s, indicating a significant difference (0.04). After the practical teaching, the p-value for the six aspects of civic literacy is less than 0.1. Tourism GIS course: The majority of students recognize the importance of civic literacy. This paper demonstrates the effective combination of tourism GIS and civics teaching so that the course can serve as both a knowledge transfer and value leadership course for students.
