Authors: Wagener Matthias Gerhard , Kiene Frederik , Buchallik-Schregel Johannes , Röhrig Petra , Ganter Martin
Published: July 2024

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

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.

Authors: Qiu Ling , Luo Wenjuan
Published: July 2024

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.

Authors: Lu Heping , Zhang Yonghong , Liu Yuan
Published: July 2024

With the help of automation technology, the efficiency and reliability of substation operations are synchronized. However, the equipment will operate under abnormal problems for a long time. If the problem is not resolved promptly, the consequences will be unimaginable. For timely detection of problems, this paper proposes a method for the construction of remote operation and maintenance systems. The remote operation and maintenance system is mainly composed of two-factor authentication, responsibility area authentication, and permission authentication. The security of remote operations and maintenance operations is guaranteed with the support of these key technologies. This paper enhances the safety and stability of automation equipment by offering remote wake-up, remote reset, historical information retrieval, and forwarding table monitoring services in the operation and maintenance service module. Adopting IoT technology, the core management module of remote management of master stations is constructed to ensure the safety of remote operations and maintenance data interaction between master stations and sub-stations. Simulation experiments are being conducted to evaluate the performance of IoT technology in remote operations and maintenance interactions at the main station. The energy consumption of the data interaction module of substation automation equipment is 0.19 and 0.012 mA for 1 hour and 1 day, respectively, for the equipment to operate for 5-10 days, where the advantages of IoT technology are reflected. The processing time of the operation and maintenance personnel under the traditional operation and maintenance and remote operation and maintenance modes were analyzed through comparative experiments, and the processing time of the device dead time was reduced from 175.46 minutes to 4.356 minutes after using the remote operation and maintenance system, and the efficiency of the operation and maintenance personnel was improved.
Correlation Mining-Based Strategies for Improving the Quality and Efficiency of Financial Data Center Operation, Maintenance, and Monitoring in Cloud-Native Models
Authors: Gao Kun , Xie Yangjun , Zhang Liang
Published: July 2024

At present, the daily operation and maintenance of large-scale data centers such as banks in China, due to a variety of reasons, often brings about the problem of unexpected events that are difficult to locate. In order to ensure that the systems running in the data center work efficiently, this paper proposes a method for improving the operation, maintenance, and monitoring of financial data centers based on the cloud-native model. First, we sequentially cleanse and process the financial center data to eliminate any negative impact and generate a time-trending correlation of financial attributes. We then apply association mining to data center operation and maintenance, using stock information as an example to analyze the operational results in stock trading transactions. The result of correlation mining is component B index (up)⇒ component A index (up), support = 12/100, confidence = 12/19, which indicates that in 100 trading days, the number of days that the component B index and the component A index rise together is 12 days, while the number of days that the component B rises alone is 19 days. In the case study examining the impact of association mining in stock trading, on March 15, 2022, the stock price experienced a rise from 11.456 to 11.498 within a mere 0.1s. The financial data operation and maintenance system, using association mining, identified this as “abnormal,” demonstrating the model’s successful detection of abnormal behavior.
Research on Operation and Maintenance Strategy of New Energy Photovoltaic Power Generation System Considering Extreme Weather Conditions
Authors: Hao Shouli , Wang Siyuan , Wang Zhijian , Qiao Yanjun , Yu Junfeng , Fan Ke
Published: July 2024

This paper employs the gray correlation analysis method to compute the correlation between irradiance, ambient temperature, wind speed, and photovoltaic power generation efficiency. This method relies on screened data for data normalization, and after processing, it determines the degree of similarity between the factors. We propose a dynamic combined maintenance strategy for PV power generation systems that considers reliability, overhaul resources, and overhaul time constraints. We propose a two-layer optimization strategy based on extreme weather factors and failure-related characteristics, and we use empirical analysis to investigate the maintenance strategy’s effectiveness. The analysis reveals a positive correlation between irradiance and PV power generation efficiency, with a multiplicative increase in the range of 1-3. In the correlation analysis of ambient temperature and wind speed variables, the power generation curve is not consistent with its trend, which is related to the influence of extreme temperature and extreme wind speed, and the meteorological factors affecting the PV power generation efficiency change at different moments of the day, where the correlation coefficient at 6:45 is 0.912. When the failure correlation strength increases to a value of 0.1, the number of repairs rises to 8. When the weather accessibility ratio is 0.2, the reduction in system availability is up to 62%. The two-layer optimization strategy, which considers extreme weather factors and failure-related characteristics, is both economical and universal.
Application of JSA, a Sentiment Analysis Model in Chinese Language and Literature, to Sentiment Recognition in Classical Poetry
Authors: Li Yali
Published: July 2024

Classical poetry embodies the essence of traditional Chinese culture, and its lyricism and infectiousness provide an ideal platform for educating about emotions. However, due to the West’s influence in modern times, the teaching of classical poetry has not expanded to include the emotional aspect. Therefore, this paper establishes the JSA model as the research model for recognizing emotions in classical poetry, based on an analysis of existing methods for recognizing emotions in Chinese literature. Upon scrutinizing the JSA model’s construction, we discovered that it overly relies on the distribution of emotions for theme generation. Consequently, this paper enhances the JSA model by situating the emotion layer between the theme layer and the word layer, builds the reverse JSA model, and employs Bayesian estimation to estimate the model’s parameters. In this paper, we use classical poems as an example to demonstrate how to analyze the sentiment of classical poems by recognizing tone auxiliaries. The improved JSA model’s emotion recognition effect closely aligns with the actual expression effect of the poems, demonstrating the effective application of the advanced JSA model in this paper for emotion recognition of classical poems.
Optimization of coal chemical process parameters and energy saving and emission reduction based on genetic algorithm
Authors: Song Xiang
Published: July 2024

Coal is an important energy resource. How to utilize it efficiently and cleanly is a hot topic nowadays. In the coal gasification process, the process parameter indexes have a significant impact, and the uncertainty of these factors will lead to a decrease in the quality of gas production. Therefore, in this paper, the uncertainty of process parameters is considered, and Aspen plus software with the Monte Carlo method is used to simulate the coal chemical process and measure the effect of uncertainty of process parameters on the yield of the coal gasification process. On this basis, in addition, coal flow rate, pressure, and steam/oxygen are taken as the process parameters and optimized, and three sets of multi-objective optimization models are established with gas calorific value, gasification efficiency, and gas yield, respectively, which are solved by improved multi-objective genetic algorithm based on crossover operator and variational operator to obtain Pareto curves, so as to adjust the parameter values according to the actual needs. The results show that the fluctuation of pressure has a big influence on the carbon conversion rate and gasification efficiency, and the carbon conversion rate and gasification efficiency can be made more stable by controlling the change of pressure. The improved genetic algorithm NSGA-II can reach the actual optimal objective function value in both high and low iteration times, providing the required parameters for the decision maker, and the optimal program results in TEC of 402,758 kW and CO2 content of 0.12%, which is effective in energy saving and emission reduction.
The trajectory of technological exchanges and modern communication technologies in the context of opening up to the outside world in the late Qing and early Republic of China
Authors: Liu Yong
Published: July 2024

During the end of the Qing Dynasty and the beginning of the Republic of China, the development of communication technology was closely correlated with societal progress. The social turmoil in the late Qing and early Republican periods, the social situation of “internal and external problems,” and the trend of “coming in” and “going out” of technological exchanges contributed to the introduction of modern communication technology, newspapers and magazines, and the establishment of the telegraph and the telephone. This led to the introduction of modern communication technology, represented by the telegraph and telephone, as well as the rise and establishment of newspapers and magazines. The national telegraph and the May Fourth Movement further enhanced the influence of the telegraph and communication technology on social development. The study analyzes the sources of funds, the number of subscribers, the number of telephone offices, the mileage of lines, the development of governmental telegraphs in each province, and the development of telegraphs in each country. It explores the development trend of communication technology in the late Qing Dynasty and the early Republic of China, taking into account the interactions between the social conditions of the late Qing Dynasty and the development of telegraphs. Based on the monthly revenue of the telephone bureau, the Beijing Telephone Bureau’s installation fee in 1909 was approximately 1,799 yuan, with the telephone fee and the Electricity Bureau’s appropriation primarily financing its construction. Towards the end of the Qing Dynasty, the Beijing Telephone Bureau extended its telegraph lines and increased the number of users. By 1911, the telegraph lines’ mileage had reached about 99,979 miles, indicating a relatively rapid development. However, the telegraph business remained significantly behind that of other countries.

Published: July 2024

Study aim

The aim of the present study was to assess the effect of roll-over self-massage on the occurrence of symptoms of delayed post-workout muscle soreness after Tabata training.

Material and methods

The research involved 81 people, randomly divided into two groups. A series of three roller self-massages was applied by members of Group 1 (n = 33). Persons assigned to control Group 2 (n = 48) did not undergo any procedures supporting the post-workout recovery. All participants performed training of lower limb muscles, according to the Tabata protocol. Then the frontal surface of the thighs was tested with a thermal imaging camera. The intensity of pain was measured (by the Visual Analogue Scale – VAS) after 24, 48 and 72 hours.

Results

The highest average pain level in Group 1 was recorded at the second measurement, i.e. 24 hours after training, and in Group 2 after 48 h. In the study group, a significantly lower result was observed on each successive day. The differences between the groups in pain levels measured 48 and 72 hours after exercise were statistically significant (p < 0.05).

Conclusion

Self-massage with a roller accelerated muscle regeneration. It can therefore be an effective procedure to support post-workout recovery, especially for athletes during the start period.
Analysis of the significance of echocardiographic signs of right ventricular dysfunction for predicting the outcome of heart failure with reduced left ventricular ejection fraction
Authors: Skidan V. I. , Pavlyukova E. N. , Nartsissova G. P. , Voronkov V. M. , Astapov D. A. , Rosseykin E. V.
Published: July 2024

Objective: to determine the ultrasound signs of right heart dysfunction, which increase the prognostic value of the recommended parameters of left ventricular (LV) dysfunction in patients with heart failure with reduced ejection fraction (HFrEF).

Materials and methods. The prospective study included 79 patients with HFrEF LV with clinical manifestations of chronic heart failure functional class III according to the New York Heart Association (HF NYHA Class III) in 52 patients (65.8%) and HF NYHA Class IV in 27 (34.1%). The primary end point was death during a follow-up period of up to 3 years while waiting for heart transplantation.

Results. Overall mortality was 33 patients (41.7%), 17 (21.5%) during the 1st year of follow-up. Regression analysis revealed the following independent ultrasound predictors of poor prognosis: LV ejection fraction on 3D-echocardiography (3DE LVEF), p = 0.014; global longitudinal strain of the LV (GLS LV), p = 0.010, and of the interventricular septum basal segment (IVSLS BS), p = 0.012; mean longitudinal strain of the basal segment of the right ventricle free wall (FWLS BS RV), p = 0.003. Changes in the configuration and dilatation of the LV cavity, an increase in LV end-diastolic pressure, impaired contractility, and strain of the LV myocardium can affect the function of the right ventricle (RV) through the common interventricular septum (IVS). Dilatation of the RV due to an increase in the end diastolic area (RV EDA) of more than 30 cm2 (p = 0.012) and end systolic area (RV ESA) of more than 25 cm2 (p = 0.001), an increase in the volume of the right atrium (3DE AKI) of more than 100 ml (p = 0.036), and a decrease in the % inspiratory collapse of the inferior vena cava (% IVC) less than 30% (p = 0.005) demonstrated a prognostic significance in the observed patients. A decrease in the deformation properties of the pancreas due to the longitudinal component and impaired strain of the basal segment makes a greater contribution to RV dysfunction (FWLS BS, % < -15% (p < 0.001)).

Conclusions. RV dysfunction in patients with HFrEF is an unfavorable prognostic factor, independently associated with existing LV dysfunction. The most significant ultrasound sign for surveillance prediction of patients with LV HFrEF and RV dysfunction are indicators of ventricular myocardial deformation. Remodeling of the right chambers and dysfunction of the RV is a trigger for the separation of the RV and pulmonary artery, which ultimately leads to adverse outcomes.

Authors: Ozerskaya I. A. , Kazaryan G. G. , Gus A. I.
Published: July 2024

Objective: to evaluate the dynamics of echographic parameters of structural changes in the endometrium depending on the morphological type of chronic endometritis (CE) before and after etiotropic therapy.

Material and methods. A retrospective cohort based on the results of examination of 140 patients of reproductive age with a verified diagnosis of CE before and after complex etiotropic therapy. A pelvic ultrasound was performed in the 1st phase of the menstrual cycle with measurements of the endometrial and uterine volume, followed by a calculation of the percentage endometrial/uterine volume ratio (EV/UCV). The groups of hypoplastic, mixed, and hyperplastic morphotypes were formed according to the values of EV/UCV. The B-mode examination included the assessment of the structure and echogenicity of the uterine cavity mucosa; the line of closure or divergence of the endometrial layers; the external contour of M-echo; the presence of liquid in the uterine cavity, and acoustic artifacts, in particular reverberation, as a sign of gas bubbles.

Results. An increase in the thickness and volume of the endometrium, and EV/UCV was obtained after therapy  in the hypoplastic morphotype. There were no changes in the thickness or volume of the endometrium in the mixed morphotype. A significant decrease in the thickness and volume of the endometrium, and EV/UCV were found in the hyperplastic morphotype. In all morphotypes, the endometrium remained mostly hyperechoic and heterogeneous, with an abnormal midline.

Conclusion. The hypoplastic and mixed morphotypes are characterized by more persistent endometrial changes that are difficult to treat. Pathological signs were eliminated much more often in the hyperplastic morphotype. The results of the study demonstrate the absence of a complete reduction in the analyzed ultrasound criteria of CE after end of treatment for all morphological types.

La presente contribución tiene como objetivo presentar algunos temas clave que se destacan en la literatura sobre el desarrollo del saneamiento y los retos para acceder a dicho servicio en zonas rurales, exhibiendo la alternativa de saneamiento ecológico como una opción que, si bien presenta desafíos, puede constituirse en una iniciativa para avanzar en la cobertura de dicho servicio. En primer lugar, se pretende dar cuenta de cómo fueron evolucionando las soluciones de saneamiento a nivel mundial, respondiendo a situaciones concretas de asociaciones con enfermedades. En segundo, se retoman algunos de los estudios que se han desarrollado, partiendo de dos conceptos considerados nodales para abordar el acceso a este servicio básico: centralización y descentralización. Finalmente se plantea la relevancia de impulsar el saneamiento ecológico, identificando algunos desafíos para avanzar en la universalidad del acceso a este servicio, cumpliendo de esta manera, el Objetivo de Desarrollo Sostenible Seis, de la Agenda 2030 de Desarrollo Sostenible.
