Improving the technological process of balancing electric machine rotors on a balancing machine
Authors: Shostak Yaroslav , Holovashchenko Oleh , Reshetnikov Yuriy , Tkachenko Viktor 
Published: September 2024

The object of research is the process of dynamic balancing of rotors on a balancing machine in the process of restoring electric machines.
The work is aimed at improving the quality of balancing rotors in the process of major repairs of traction electric motors for electric trains. The problem addressed was the quality of balancing the rotors of electric machines on stationary balancing machines. According to the conventional balancing technology, the rotor to be balanced is mounted on the supports of the balancing machine with support surfaces that usually have mechanical defects. These defects cannot be eliminated by machining due to the peculiarities of rotor repair technology. Theoretical and experimental studies of the effect of damage to the rotor support surfaces on the balancing parameters have been carried out. It has been proven that the properties of the bearing surfaces of the rotor during its balancing on a balancing machine significantly affect the results of determining the imbalance. At the same time, the difference in the mass values of balancing loads can reach 25 %. This is because damage to the bearing surfaces of the rotor generates false signals unrelated to the imbalance.
In order to increase the accuracy of determining the mass of balancing loads during rotor balancing, it is proposed to improve the technological process of balancing. The improvement involves the inclusion of a frequency filter in the signal conversion chain of acceleration sensors. The filter is designed to separate signals with a frequency greater than the rotational frequency of the rotor.
A condition for the practical application of the research results is the expediency of introducing a frequency filter of signals of acceleration sensors with a threshold frequency of filtering signals that exceeds the rotational frequency of the rotor into the schematic diagram of the balancing machine.

Authors: Snell Cordero Jessica , Godínez-Alvarez Héctor 
Published: September 2024

The association between cacti and nurse plants has been reviewed by different authors. These reviews however were qualitative because only evaluated aspects such as species identity of cacti and nurse plants, probable explanatory causes of their association, and location of study sites. To our knowledge, there are no quantitative reviews that have evaluated the association between cacti and nurse plants for different subfamilies, tribes, and growth forms of cacti and nurse plants, and different plant communities and soil properties. To address these issues, we performed a quantitative review of the studies on the association between cacti and nurse plants. The studies were searched in the ISI Web of Knowledge from 1986 to 2021. Data obtained from studies were analyzed with the relative risk ratio and ratio of medians. Most studies on the association between cacti and nurse plants were performed mainly in Mexico and the USA. Globose, cylindrical, and columnar cacti of the subfamily Cactoideae, and tribes Cacteae, Cereeae, and Echinocereeae were associated to nurse plants of Asteraceae, Euphorbiaceae, and Fabaceae. However, other subfamilies (Opuntioideae) and tribes (Notocacteae) of cacti, and families (Asparagaceae) of nurse plants were not associated. Nurse plants ameliorated temperature, moisture, and nitrogen of soil. The association between cacti and nurse plants occurred in desert shrubland and tropical dry forest. Further studies are needed on the association between cacti and nurse plants that consider more cactus subfamilies and tribes in countries with high cactus diversity in Central and South America.

Abstract

Background
Head impacts, particularly, non-concussive impacts, are common in sport. Yet, their effects on the brain are poorly understood. Here, we investigated the acute effects of non-concussive impacts on brain microstructure, chemistry, and function using magnetic resonance imaging (MRI) and other techniques.
Results
Fifteen healthy male soccer players completed this randomised, controlled, crossover trial. Participants completed a soccer heading task (‘Heading’; the Intervention) and an equivalent ‘Kicking’ task (the Control); followed by a series of MRI sequences between ~ 60–120 minutes post-tasks. Blood was also sampled, and cognitive function assessed, pre-, post-, 2.5 hours post-, and 24 hours post-tasks. Brain chemistry: Heading increased total N-acetylaspartate (p = 0.012) and total creatine (p = 0.010) levels in the primary motor cortex (but not the dorsolateral prefrontal cortex) as assessed via proton magnetic resonance spectroscopy. Glutamate-glutamine, myoinositol, and total choline levels were not altered in either region. Brain structure: Heading had no effect on diffusion weighted imaging metrics. However, two blood biomarkers expressed in brain microstructures, glial fibrillary acidic protein and neurofilament light, were elevated 24 hours (p = 0.014) and ~ 7-days (p = 0.046) post-Heading (vs. Kicking), respectively. Brain function: Heading decreased tissue conductivity in five brain regions (p’s < 0.001) as assessed via electrical properties tomography. However, no differences were identified in: (1) connectivity within major brain networks as assessed via resting-state functional MRI; (2) cerebral blood flow as assessed via pseudo continuous arterial spin labelling; (3) electroencephalography frequencies; or (4) cognitive (memory) function.
Conclusions
This study identified chemical, microstructural and functional brain alterations in response to an acute non-concussive soccer heading task. These alterations appear to be subtle, with some only detected in specific regions, and no corresponding functional deficits (e.g., cognitive, adverse symptoms) observed. Nevertheless, our findings emphasise the importance of exercising caution when performing repeated non-concussive head impacts in sport.

Abstract

Background
The pink bollworm (Pectinophora gossypiella) is a major pest of cotton, causing economic losses by damaging seeds and fiber. Cotton growers typically use systemic and broad-spectrum insecticides for its management, which pose risks to human health and the environment. Consequently, there is a need for eco-friendly alternatives. This study evaluates the bio-efficacy of the entomopathogenic fungus Metarhizium anisopliae strain TMBMA1 against pink bollworm and assesses its compatibility with major insecticides. Additionally, to comprehend the dynamics of colonization and the infection processes of EPF, scanning electron microscopy (SEM) of infected larvae was carried out.
Result
We challenged second instar PBW larvae to eight different concentrations (1×10³ to 1×10¹⁰ conidia ml-1) of M. anisopliae TMBMA1. The highest mortality (100%) occurred at the highest concentrations i.e., 1×10⁹ and 1×10¹ spores ml-1, while the lowest mortality rate (46.6%) was observed at 1×10³ spores ml-1 concentration compared to control (3.33%). TMBMA1's biocontrol efficacy was validated by Probit analysis, exhibiting an exceptionally low LC50 value of 7.1 × 10⁵. The comparative evaluation revealed that M. anisopliae TMBMA1 performed par excellent with insecticide (Cypermethrin 20EC) giving 100% mortality, both being superior to a commercial product of M. anisopliae (60%). The EPF strain was profusely colonized on both the internal and external surfaces of PBW larvae, according to SEM analysis. Compatibility studies with insecticides revealed > 98% and > 96% reduction in the sporulation of M. anisopliae due to the treatment of Emamectin Benzoate 1.5% + Profenofos 35% WDG and Profenofos 50EC, respectively. In contrast, Cypermethrin 10% EC, Emamectin Benzoate 5% SG and Neem Seed Kernel Extract (NSKE 1500 PPM) treatments reported minimal reduction (11%, 13% and 21% respectively) in spore production.
Conclusion
According to the current investigations, the M. anisopliae strain TMBMA1 exhibits high virulence against PBW and offers a promising eco-friendly solution for managing this pest. It shows significant potential to proliferate on both external and internal surfaces of PBW. This strain can be integrated into PBW management programs with chemical insecticides, thereby improving pest control and lessen environmental impact.

Abstract

Background: The combined surgery with tibial intramedullary(IM) rod fixation across the ankle for the treatment of Crawford IV congenital pseudarthrosis of the tibia (CPT) is the most classic and effective surgical treatment method. The aim of this study is to explore the long-term clinical efficacy of combined surgery for the treatment of Crawford IV congenital pseudarthrosis of the tibia(CPT).
Methods：A retrospective analysis was conducted on 82 cases of Crawford IV CPT who underwent combined surgical treatment with tibial intramedullary(IM) rod fixation through the ankle, to evaluate their long-term clinical efficacy and postoperative complications.
Results：The average surgical age of the patient was (43.17 ± 13.40) months (range: 18-96 months), with an initial bone healing rate of 100%, and an average postoperative follow-up time of (119.78 ± 20.08) months (range: 84-146 months); At the last follow-up, there were a total of 20 cases of re fractures, including 15 cases in the complete insertion of IM rods into the tibial medullary cavity group, 2 cases in the tibial IM rod across the ankle fixation group, and 3 cases in the tibial IM rod removal group; There were a total of 28 cases of developmental bending and angular deformity of the tibial shaft after bone healing, including 26 cases in the complete insertion of IM rods into the tibial medullary cavity group, 0 cases in the tibial IM rod across the ankle fixation group, and 2 cases in the tibial IM rod removal group；All cases in the complete insertion of IM rods into the tibial medullary cavity group showed tibial IM rods deviating from the center of the medullary cavity, with a displacement rate of up to 100%.
Conclusions：The combined surgery of tibial IM rod fixation across the ankle for the treatment of Crawford IV CPT has a high initial bone healing rate and definite therapeutic effect, but there are still many postoperative complications. The fixation status of tibial IM rods is an important influencing factor for tibial shaft developmental angular bending deformity and re fractures after initial bone healing.

Abstract

Redox status is closely associated with the development and progression of cancer, which can be modulated by long non-coding RNA (lncRNA). A series of previous studies have demonstrated that redox regulation can be treated as a potential treatment option for cancer. However, the redox-related lncRNA predictive signature of bladder cancer (BCa) still remains unknown. The purpose of our study is to construct a redox-related lncRNA signature for better prediction of BCa patients’ prognosis. We downloaded transcriptome and clinical data from the Cancer Genome Atlas (TCGA) database. The prognostic redox-related lncRNAs were identified by univariate Cox regression, least absolute shrinkage and selection operator (LASSO) regression, and multivariate Cox regression analysis and two risk groups were established. A comprehensive analysis corresponding to clinical features between high-risk and low-risk groups was conducted. Eight redox-lncRNAs (AC018653.3, AC090229.1, AL357033.4, AL662844.4, AP003352.1, LINC00649, LINC01138, MAFG-DT) were selected and constructed the risk model. The overall survival (OS) in high-risk group was worse than that in low-risk group (p < 0.001). The redox-related lncRNA signature has a better predictive accuracy than clinicopathological characteristics. GSEA analysis showed the MAPK signaling pathway and WNT signaling pathway were enriched in the high-risk group. Compared with the low-risk group, the patients in high-risk group were more sensitive to cisplatin, docetaxel, and paclitaxel. Furthermore, IGF2BP2, a potential target gene of MAFG-DT, was overexpressed in tumor tissues and was correlated with OS. Our study proved that the predictive signature constructed by eight redox-related lncRNAs can independently and accurately predict the prognosis of BCa patients.
