Prognostic is central to manufacturing and infrastructure management. The development of new methods for determining the residual resource of equipment is an important task aimed at increasing the efficiency of using industrial electrical complexes. Solving the problem of reliably determining the state of power equipment in the mining and metallurgical complex makes it possible to move from an outdated system of scheduled preventive maintenance to maintenance based on the current state of the unit. Complex technical systems are characterized by complex nonlinear interactions between their constituent elements, complex scenarios of cause-and-effect relationships between hazardous, probabilistic events and processes occurring during their operation. Therefore, methods and tools are being developed to assess and manage wear mechanisms in high-risk industries. The sources of information in the systems of technical diagnostics and control of technological processes are measuring transducers (sensors) of physical quantities. Using information from sensors and real-time operational diagnostics, the operator can predict the occurrence of malfunctions, equipment failures and process disturbances, which reduces downtime of process equipment and the occurrence of emergency situations. The article presents the results related to the development of a methodology for assessing the residual life of industrial equipment. The methodology uses probabilistic mathematical methods to predict the remaining service life and information collected during audits and equipment monitoring. Along with the classical methods, methods are presented based on the use of the entire potential of the modern element base of microprocessor technology and technologies for the use of artificial neural networks, machine learning, "big data".

Published: August 2022

Recently, a special direction in solving the problem of intensification of convection heat exchange, which is based on the idea of influencing the micro- and macrostructure of the flow of heat carriers by various swirls in the channels of their movement, has been widely developed in industrial heat engineering. Despite the huge number of publications on this topic, the issue of improving the effectiveness of heat exchangers remains far from its final solution. The research is aimed at studying the possibilities and limits of increasing the efficiency of heat transfer in the modified trapezoidal helical profile of the inner surface of the pipes of the fuel oil heater PM-40-15. To achieve this goal, the method of computer simulation using SolidWorks software was used. In this program, a geometric model of a fuel oil heater was created with both smooth standard pipes and modified pipes with trapezoidal profiles with a height of h = 2, 3 and 4 mm and relative steps of the screw profile S/D = 0.6, 0.8, 1.0, 1.2 and 1.5. The temperature of fuel oil M100 at the inlet of the fuel oil heater was taken to be 60°С, and the temperature of the walls of the pipes washed with superheated steam at a pressure of 1.0 MPa, 200°С. These parameters corresponded to the nominal mode of operation of the fuel oil heater PM-40-15. As a result of the research, it was found that the best efficiency indicators are achieved on pipes with a profile height h = 2 mm and a relative step S/D = 0.8.

OBJECTIVE

For patients with cervical and thoracolumbar AO Spine type C injuries, the authors sought to 1) identify whether preoperative vertebral column translation is predictive of a complete spinal cord injury (SCI) and 2) identify whether preoperative or postoperative vertebral column translation is predictive of neurological improvement after surgical decompression.

METHODS

All patients who underwent operative treatment for cervical and thoracolumbar AO Spine type C injuries at the authors’ institution between 2006 and 2021 were identified. CT and MRI were utilized to measure vertebral column translation in millimeters prior to and after surgery. A receiver operating characteristic (ROC) curve was generated to predict the probability of sustaining a complete SCI on the basis of the amount of preoperative vertebral column translation. ROC curves were then used to predict the probability of neurological recovery on the basis of preoperative and postoperative vertebral column translation.

RESULTS

ROC analysis of 67 patients identified 6.10 mm (area under the curve [AUC] 0.77, 95% CI 0.650–0.892) of preoperative vertebral column translation as predictive of complete SCI. Additionally, ROC curve analysis found that 10.4 mm (AUC 0.654, 95% CI 0.421–0.887) of preoperative vertebral column translation was strongly predictive of no postoperative neurological improvement. Residual postoperative vertebral column translation after fracture reduction and instrumentation had no predictive value on neurological recovery (AUC 0.408, 95% CI 0.195–0.622).

CONCLUSIONS

For patients with cervical and thoracolumbar AO Spine type C injuries, the amount of preoperative vertebral column translation is highly predictive of complete SCI and the likelihood of postoperative neurological recovery.

Low birth weight (LBW) infants are one of the risk factors that contribute to infant mortality, especially during the perinatal period. The incidence of LBW babies occurs every year at the Puledagel Health Center, namely in 2018 there were 13 cases (6.07%), in 2019 there were 12 cases (5.4%), and in 2020 to September there were 15 cases (8 ,7%).The purpose of this research is to find out the factors that influence the incidence of LBW and to find out whether there is a relationship between the independent variable and the dependent variable. The dependent variable of this study was low birth weight (LBW) infants, while the independent variables of this study were maternal age, education, parity, gestational age, gestational age, preeclampsia, ANC quantity, LILA, and Hb levels. The research design used analytic observation with a case control approach with a sample population of 132 respondents who were taken by total sampling technique for LBW and random sampling technique for LBW.The results of the study indicate that the independent variable that affects the incidence of low birth weight babies (LBW) is the mother's gestational age. Maternal gestational age produces a p-value of 0.001 , so that this variable has a significant relationship with the incidence of low birth weight (LBW) infants. Variables that do not affect the incidence of LBW are age, education, parity, pregnancy interval, preeclampsia, quantity of ANC, LILA, and Hb levels.
Loss of genes in chromosome arms 5q and 16q in breast cancer
Authors: Voutsadakis Ioannis A.
Published: August 2022

INTRODUCTION: Losses of genetic material from chromosomes 5q and 16q commonly occur in sub-sets of breast cancer. Their significance from a pathophysiologic point of view is not well-defined. METHODS: This study uses publicly available genomic data from extensive breast cancer datasets to define the landscape of losses in chromosomal arms 5q and 16q in the two sub-types of breast cancer they most commonly occur, basal-like and luminal A cancers, respectively. RESULTS: It is shown that dozens of genes from these chromosomal arms are putatively hemi-deleted in few samples each. No individual gene from either 5q or 16q shows an incidence of deep deletion above 10% in the cohorts with basal-like and luminal A cancers or in the whole cohorts. A few tumor suppressor genes are deleted in a small number of samples, less than 5% in each cohort. Losses of 5q or 16q confer no survival advantage in either the basal-like or the luminal A cohorts from TCGA that harbor them. CONCLUSION: Results suggest that there are no individual genes in chromosomes 5q and 16q whose loss can be implicated in a dominant pathophysiologic sequence of events in breast cancer or its sub-sets.

The INDIGO trial investigated the effectiveness of a six-month PA intervention for inactive older adults at risk of cognitive decline with subjective cognitive decline or mild cognitive impairment. Objective: This follow-up study aimed to collect feedback from INDIGO participants about their experience of involvement in the trial, including barriers and enablers to longer-term maintenance of PA. Methods: A qualitative study using semi-structured individual interviews was conducted and transcripts analyzed thematically. All INDIGO trial completers were invited, with 29 participating (follow-up period 27–66 months post-baseline). Results: At long-term follow-up, participants described INDIGO trial participation as beneficial. The theme of “Motivation” (subthemes: structure and accountability, knowledge and expected benefits, preferences and motivation, tools) followed by “Situation” (subthemes: environment and time, social aspects, aging and physical health) appeared to be critical to PA “Action". Most participants had a positive view of goal-setting and peer mentoring/support, but there was some polarization of opinion. Key factors to longer-term “Maintenance” of PA were self-efficacy and perceived benefits, habit formation, and for some participants, enjoyment. Conclusion: PA interventions for older adults at risk of cognitive decline should include behavior change techniques tailored to the individual. Effective techniques should focus on “Motivation” (particularly structure and accountability) and “Situation” factors relevant to individuals with the aim of developing self-efficacy, habit formation, and enjoyment to increase the likelihood of longer-term PA maintenance.

The unbalanced magnetic pull (UMP) is one of the main vibration sources of the motorized spindle. A calculation model of UMP in a synchronous motorized spindle considering the magneto-thermal coupling is proposed in this paper. The finite element analysis models of the electromagnetic field and the temperature field of a motorized spindle are first established. Then a two-way coupling analysis method considering the effect of temperature variations on electromagnetic material properties of the motor is proposed. An experiment is conducted to verify the efficiency of this method. The thermal deformations of the spindle are calculated and used to analyze the air-gap variations between rotor and stator of the built-in motor. The 3D finite element electromagnetic model is adopted to calculate the UMP in the motorized spindle. The analysis results show that the eccentricity caused by thermal deformation can generate large UMP in the motorized spindle.
Online User Authentication System Using Keystroke Dynamics

Published: August 2022

Nowadays, people become more connected to the internet using their mobile devices. They tend to use their critical and sensitive data among many applications. These applications provide security via user authentication. Authentication by passwords is a reliable and efficient access control procedure, but it is not sufficient. Additional procedures are needed to enhance the security of these applications. Keystroke dynamics (KSD) is one of the common behavioral based systems. KSD rhythm uses combinations of timing and non-timing features that are extracted and processed from several devices. This work presents a novel authentication approach based on two factors: password and KSD. Also, it presents extensive comparative analysis conducted between authentication systems based on KSDs. It proposes a prototype for a keyboard in order to collect timing and non-timing information from KSDs. Hence, the proposed approach uses timing and several non-timing features. These features have a demonstrated significant role for improving the performance measures of KSD behavioral authentication systems. Several experiments have been done and show acceptable level in performance measures as a second authentication factor. The approach has been tested using multiple classifiers. When Random Forest classifier has been used, the approach reached 0% error rate with 100% accuracy for classification.
Swallow Safety and Laryngeal Kinematics: A Comparison of Dysphagia Between Parkinson’s Disease and Cerebrovascular Accident
Authors: Dumican Matthew , Watts Christopher
Published: August 2022

Background: Cerebrovascular accident (CVA) and Parkinson’s disease (PD) are well established etiologies of dysphagia. However, differing physiological mechanisms underlying dysphagia may exist between these two causes. There have been limited investigations specifically comparing dysphagia between these two groups. Comparing dysphagia presentation in two different populations may improve clinical expectations, guide treatment approaches, and inform future research. Objective: This study examined the differences in presentation of dysphagia between PD and CVA. Dysphagia presentation, swallow safety, and laryngeal kinematics were compared between two clinical cohorts. What factors best predicted airway invasion in each group were explored. Methods: 110 swallow studies of individuals with PD and CVA who were referred for swallowing evaluation were obtained. Each video was analyzed for quantitative dysphagia presentation using the Videofluoroscopic Dysphagia Scale (VDS), swallow safety using the Penetration-Aspiration scale, and kinematic timings of the laryngeal vestibule (time-to-laryngeal vestibule closure [LVC] and closure duration [LVCd]). Results: Frequencies of penetration or aspiration were similar between groups. The PD group displayed significantly greater pharyngeal stage swallow impairment than CVA, with more frequent reduced laryngeal elevation and increased vallecular residue. The CVA group displayed significantly greater oral stage impairment, with prolonged oral transit times. Time-to-LVC was significantly prolonged and was the strongest predictor of airway invasion in the PD group, but not for CVA. Conclusion: Similar airway invasion rates for PD and CVA indicate the importance of screening for dysphagia in PD. Laryngeal kinematics as significant contributors to airway invasion in PD but not for CVA highlight the need for further research into these mechanisms and for targeted treatment approaches to dysphagia.

Exosomes in the visual system: New avenues in ocular diseases
Authors: Manukonda Radhika , Attem Jyothi , Yenuganti Vengala Rao , Kaliki Swathi , Vemuganti Geeta K.
Published: August 2022

Exosomes are a subgroup of membrane-bound extracellular vesicles secreted by all cell types and present virtually in all biological fluids. The composition of exosomes in the same cell type varies in healthy and disease conditions. Hence, exosomes research is a prime focus area for clinical research in cancer and numerous age-related metabolic syndromes. Functions of exosomes include crucial cell-to-cell communication that mediates complex cellular processes, such as antigen presentation, stem cell differentiation, and angiogenesis. However, very few studies reported the presence and role of exosomes in normal physiological and pathological conditions of specialized ocular tissues of the eye and ocular cancers. The eye being a protected sense organ with unique connectivity with the rest of the body through the blood and natural passages, we believe that the role of exosomes in ocular tissues will significantly improve our understanding of ocular diseases and their interactions with the rest of the body. We present a review that highlights the existence and function of exosomes in various ocular tissues, their role in the progression of some of the neoplastic and non-neoplastic conditions of the eyes.

Application of Ionophores in Cattle Diets
Authors: Hersom Matt , Thrift Todd
Published: August 2022

Beef cattle producers should consider using ionophores to increase calf gain and gain efficiency in a cost-effective manner. Ionophores are feed additives used in cattle diets to increase feed efficiency and body weight gain. They are compounds that alter rumen fermentation patterns. Ionophores can be fed to any class of cattle and can be used in any segment of the beef cattle industry. Similar to many other feed additives, ionophores are fed in very small amounts and supplied via another feedstuff as carrier for intake. Ionophores decrease incidence of coccidiosis, bloat, and acidosis in cattle.

Managing Mexican Petunia (Ruellia simplex C. Wright) in the Home Landscape
Authors: Adams Carrie A. Reinhardt , Wiese Christine , Lee L. C. , Wilson Sandra B. , Smith A. M. , Freyre Rosanna
Published: August 2022

Environmental tolerance, abundant seed production, and an ability to easily grow from plant stem sections have allowed Mexican petunia to spread into natural areas that border urban areas. The Florida Exotic Pest Plant Council lists Mexican petunia (wild-type and non-sterile cultivars) as a Category 1 invasive species, meaning that it is “altering native plant communities by displacing native species, changing community structures or ecological functions, or hybridizing with natives.” These potential changes to community structure and ecological function are of particular concern in Florida wetlands, where changes to plant communities have the potential to impact not just plant-animal interactions, but also overall hydrology on a whole watershed level.
