Electric and Magnetic Fields in Vicinity of Overhead Multi-Line Power System

Abstract —Nowadays, a multi-line power system is present in our neighbourhood to satisfy increasing need for electric power. In order to get the thorough acquaintance with electric and magnetic fields in vicinity of overhead power lines, it is necessary to determine both, the magnitude of electric and magnetic field strength, as well as their polarization. In this paper the route of two 400 kV three-phase flat configuration overhead power lines are examined. Keywords: electric field strength, magnetic flux density, polarization, power lines, multi-line power system I. I NTRODUCTION Computation of the fields produced by overhead power lines is important for studying possible effects of extremely low frequency electric and magnetic field on a human health. The magnitudes of the fields are the highest under the power lines and decrease rapidly with the distance from the lines. From the point of view of human exposure the most critical points are those within or close to the right of way of the lines. When electric field penetrates the human body, its electrical activity is quite small, even compared to the tiny signals associated with cellular activity. Some researchers believe that power lines electric field adds a stress factor to nervous system activity. Human Radiation Effects Group [1] describe how electric field affects airborne particles: “Aerosols in the proximity of power line electric fields become polarized. The polarity of the particles reverses in concert with the alternating current, setting up an oscillatory movement. The particles become stickier and they are more likely to adhere to skin or to lung tissue. ” Electric fields are perturbed by conducting objects, including the vegetation, most building materials and people. The electric fields are screened by the building materials, by factors typically ranging from 10 to 1000 times [2]. Magnetic field is difficult to shield and easy penetrate most materials including vegetation, building materials and people, except ferromagnetic materials and highly conductive materials, such as aluminum and copper. One of the mechanisms of interaction between alternating magnetic fields and the human body is inducing currents in tissue. The International Commission on Non-Ionizing Radiation Protection (ICNIRP) has established a continuous electric field exposure limit of 5 kV/m and a continuous magnetic field exposure limit of 100 μT for general public at 50 Hz frequency [3]. These limit values are sometimes approached in close proximity to large transmission lines, although typical exposure is much lower. Away from the power lines field levels are much lower than proposed limits. As we can see, none of regulations are dealing with polarization of electric and magnetic field vectors. So, if low levels of fields have no influence on a human body, could we say the same for polarization of electric and magnetic fields? II. E
Relationship of 24-h ambulatory blood pressure variability with micro and macrovascular parameters and hypertension status

Objectives: Increased blood pressure variability (BPV) has been associated with an increased risk of subclinical organ damage and cardiovascular events, independently of elevated average BP values. We aimed to investigate the association of BPV indices with micro- and macrovascular parameters, some of them not previously studied. Methods: We evaluated 344 individuals (233 never-treated/newly diagnosed hypertensive and 111 normotensive individuals). BPV was assessed using average real variability (ARV) during 24-h, daytime and night-time ambulatory blood pressure monitoring, and systolic weighted standard deviation (wSD). Retinal microvascular diameter was assessed by nonmydriatic retinal photography. Arterial stiffness was assessed by pulse wave velocity (PWV) and aortic augmentation index (AIx); subendocardial variability ratio (SEVR) was used as an index of myocardial perfusion. Carotid intima-media thickness (cIMT) was measured by ultrasound. Data were analyzed using multiple regression analysis. Results: After adjusting for potential confounders, PWV and cIMT were independently associated with ARV components in the total sample (P < 0.023 and P < 0.014, respectively). Within hypertensives only PWV and cIMT were independently associated with ARV components (P < 0.002 for PWV and P < 0.003 for cIMT). In contrast, within normotensives, only retinal parameters and AIx were associated with ARV components (P < 0.017 and P = 0.013, respectively). None of the univariate correlations between vascular parameters and wSD remained significant after adjustment for potential confounders. Conclusion: Short-term BPV as assessed by ARV is independently associated with macrovascular parameters in untreated hypertensive patients, and with microvascular parameters in normotensive individuals.
Exosomes and their Cargo as a New Avenue for Brain and Treatment of CNS- Related Diseases

Extracellular Vesicles (EVs), which belong to nanoscale vesicles, including microvesicles (MVs) and exosomes, are now considered a new important tool for intercellular neuronal communication in the Central Nervous System (CNS) under physiological and pathological conditions. EVs are shed into blood, peripheral body fluids and cerebrospinal fluid (CSF) by a large variety of cells. EVs can act locally on neighboring and distant cells. EVs represent the fingerprints of the originating cells and can carry a variety of molecular constituents of their cell of origin, including protein, lipids, DNA and microRNAs (miRNAs). The most studied EVs are the exosomes because they are ubiquitous and have the capacity to transfer cell-derived components and bioactive molecules to target cells. In this minireview, we focused on cell-cell communication in CNS mediated by exosomes and their important cargo as an innovative way to treat or follow up with CNS diseases.
and Self

Video replay can be deliberately structured through planning and editing in various ways. This chapter describes the application of self modeling, in which recordings show only adaptive behavior. The term feedforward is coined to refer to video images of target skills not yet achieved, created by editing together component behaviors that are manageable for the trainee or client. Principles are presented for creating video feedforward and positive self-review, which refers to selectively compiling the best recorded examples of target skills already manageable but infrequently achieved. Applications of self modeling are reviewed and issues raised about mechanisms, limitations, and strengths are discussed. These issues include subject participation and awareness, efficacy compared with other interventions (including peer modeling and unedited replay), and when and when not to use different forms of self modeling. The methodology is summarized based on successful applications in different areas: disruptive behavior, selective mutism, depression, anxiety, sports, social skills, physical disabilities, and provider training. The chapter ends with a step-by-step description of developing and implementing a self modeling-based package for the training of social safety skills in young adults with developmental disabilities: assessment, task analysis, video capture, editing, viewing the tapes, and evaluation.
Integration of alternative energy sources into digital micro‐grids

We overview different alternative energy resources and comment on their benefits and challenges. We highlight some features of alternative and sustainable energy resources and discuss some challenges for their integration into the power grid. In view of global trend toward blending alternatives and conventional energy resources in electrical power grids, a more robust energy distribution approach is necessary. Here, we present an alternative to the power grid with great potential for integrating alternative energy sources and defining microgrids—the Controlled‐Delivery Grid (CDG). We comment how this new digital approach enhances the distribution of energy may help to resolve those challenges. We also examine the role of energy storage elements (batteries, super‐capacitors), and sustainable energy resources in this new approach to the power grid. We provide some numerical analysis on the performance of energy distribution of the CDG and some experimental results that highlight some of its features. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 155–164, 2018
Longitudinal Predictors of Coronavirus-Related PTSD among Young Adults from Poland, Germany, Slovenia, and Israel

The aim of this study was to reveal longitudinal predictors of coronavirus-related PTSD and the moderating roles of country, sex, age, and student status among young adults from Poland, Germany, Slovenia, and Israel. We included the following predictors: perceived stress, exposure to COVID-19, perceived impact of COVID-19 on well-being in socioeconomic status (PNIC-SES) and social relationships (PNIC-SR), fear of COVID-19, fear of vaccination, and trust in institutions. We conducted the study online among a representative sample of 1723 young adults aged 20–40 (M = 30.74, SD = 5.74) years in February 2021 (T1) and May–June 2021 (T2). We used McNemar’s χ2 and the paired samples Student’s t-test to test differences over time. We assessed the relationships between variables using Pearson’s correlation. We performed structural equation modeling (SEM) to examine the associations between variables at T1 and T2. We used a lagged regression model to examine the causal influences between variables across different time points (T1 and T2). The results showed that all variables decreased over time, except exposure to COVID-19. The rates of infected, tested, and under-quarantine participants increased. The rates of those who lost a job and experienced worsening economic status decreased. The rate of hospitalized participants and those experiencing the loss of close ones did not change. Higher perceived stress, fear of COVID-19, fear of vaccination, and trust in institutions were significant longitudinal predictors of coronavirus-related PTSD regardless of country, sex, age, and student status. Institutions should provide more accurate programs for public health, so trust in institutions can be a protective and not a risk factor in future traumatic events.
A statistical downscaling prediction model for winter temperature over Xinjiang based on the CFSv2 and sea ice forcing

Based on a year‐to‐year increment approach, a statistical downscaling model is developed for winter temperature prediction over Xinjiang of northwest China by using the predicted 200‐hPa westerly wind in winter over the Ural Mountains from the Climate Forecast System version 2 (CFSv2) as well as the observed sea ice over the Barents Sea–Laptev Sea in the preceding September. The statistical downscaling hindcasts on the 1983–2018 winter temperature over Xinjiang show that the statistical downscaling method has significantly improved the prediction capability compared with the original CFSv2. Specifically, the temporal correlation coefficients increase from negative to positive in most of Xinjiang, with the values passing the significance test at 90% confidence level at 81% of the stations. The regional averaged root‐mean‐square error reduces by more than 20%. In addition, the anomaly correlation coefficient increases from 0.08 to 0.26, passing the significance test at 95% confidence level. For two typical cases of the extreme cold winter in 2011 and the extreme warm winter in 2016, the spatial distribution characteristics of temperature anomaly are well reproduced, which are generally consistent with the observations. Overall, the statistical downscaling model based on the year‐to‐year increment strategy is a relatively effective method for predicting the winter temperature in Xinjiang.

Cancer Cachexia and Antitumor Immunity: Common Mediators and Potential Targets for New Therapies

Cancer cachexia syndrome (CCS) is a multifactorial metabolic syndrome affecting a significant proportion of patients. CCS is characterized by progressive weight loss, alterations of body composition and a systemic inflammatory status, which exerts a major impact on the host’s innate and adaptive immunity. Over the last few years, the development of immune checkpoint inhibitors (ICIs) transformed the treatment landscape for a wide spectrum of malignancies, creating an unprecedented opportunity for long term remissions in a significant subset of patients. Early clinical data indicate that CCS adversely impairs treatment outcomes of patients receiving ICIs. We herein reviewed existing evidence on the potential links between the mechanisms that promote the catabolic state in CCS and those that impair the antitumor immune response. We show that the biological mediators and processes leading to the development of CCS may also participate in the modulation and the sustainment of an immune suppressive tumor microenvironment and impaired anti-tumor immunity. Moreover, we demonstrate that the deregulation of the host’s metabolic homeostasis in cancer cachexia is associated with resistance to ICIs. Further research on the interrelation between cancer cachexia and anti-tumor immunity is required for the effective management of resistance to immunotherapy in this specific but large subgroup of ICI treated individuals.
Energy poverty indicators: A critical review of methods

The widespread recognition of energy poverty as a distinct societal and policy challenge in the EU has resulted in a surge in the number and complexity of energy poverty metrics. Drawing from the body of white and grey literature on domestic energy deprivation indicators now available, the paper offers a review-based discussion on the risks of uncritically elaborating and reporting energy poverty statistics. It identifies key conceptual and methodological challenges including: the diversity of domestic energy services and household needs accounted for; the distinction between actual and required domestic energy expenditures; the setting of thresholds and energy poverty lines; the equivalisation of household incomes and energy expenditures; the consideration of housing costs; the stated, subjective character of responses to survey questionnaires; the measurement of the ‘depth’ of energy poverty; issues surrounding measurement units and weighted indices; and issues around the socio-demographic, spatial and temporal representativeness of data. Based on the reviewed evidence and author’s experience, the paper argues against official, single-indicator energy poverty metrics like the UK’s low income-high cost and advocates for multiple-indicator approaches that explicitly acknowledge the shortcomings of each of the methods implemented.
Microbiome Changes in Connective Tissue Diseases and Vasculitis: Focus on Metabolism and Inflammation

The microbial community acts as an active player in maintaining homeostasis and immune functions through a continuous and changeable cross-talk with the host immune system. Emerging evidence suggests that altered microbial composition, known as dysbiosis, might perturb the delicate balance between the microbiota and the immune system, triggering inflammation and potentially contributing to the pathogenesis and development of chronic inflammatory diseases. This review will summarize the current evidence about the microbiome-immunity cross-talk, especially focusing on the microbiota alterations described in patients with rheumatic diseases and on the recent findings concerning the interaction between microbiota, metabolic function, and the immune system.
Experimental study of local and modal approaches to active vibration control of elastic systems

Two different methods, local and modal, are suggested to control systems with distributed parameters, each of them having its own advantages and drawbacks. The aim of the present research is to carry out experiments aiming in comparison of these 2 methods for the problem of suppression of forced bending vibrations of a thin metal beam. Two pairs of piezoelectric sensors and actuators are attached to the beam in each control system considered. Their locations are chosen so as to provide the most efficient measurement and excitation of the first and second vibration modes of the beam. Frequency methods of the automatic control theory are employed to design stable control systems that can efficiently suppress bending vibrations of the beam with the first and second resonance frequencies. As a result, control systems with the desired performance are created on the basis of both local and modal methods. The obtained modal system works efficiently for both resonances, whereas the local systems demonstrate appropriate performance either at the first or at the second resonance frequency only. This difference is due to the fact that in the case of modal control, each control loop corresponds to a particular vibration mode and can be designed to provide optimal performance at the required frequency. The performed benchmark study demonstrates the advantages of the modal method over the local one for the cases where it is necessary to suppress vibrations in the frequency range that contains more than one resonance frequency of the control object.
Effectiveness of Ready-to-Use Therapeutic Food Among Children With Protein-Calorie Malnutrition

Background Malnutrition develops when there is an inadequacy of one or more than one macronutrient for optimum body functioning. This study was designed to determine the effectiveness of ready-to-use therapeutic food (RUTF) in children with protein-calorie malnutrition (PCM) in terms of weight gain and mid-upper arm circumference (MUAC) improvement. Methodology This prospective observational study was done at The Department of Pediatrics, National Institute of Child Health, Karachi, Pakistan from 1st January 2021 to 31st December 2021. A total of 159 children of either gender between six and 59 months of age and diagnosed with PCM were included. All children participating in the study were asked to come back for a follow-up every two weeks until they are 12 weeks old. Outcomes were measured in terms of comparison of weight gain and MUAC at baseline and after 12 weeks of RUTF. Results Of the 159 children, 94 (59.1%) were female. The mean age was 16.8±9.2 months, and 88 (55.3%) children were aged between six to 12 months. The mean body weight was 6.8±9.7 kg. The mean MUAC was calculated to be 116±9.1 mm. There were 121 (76.1%) children who had severe acute malnutrition. One hundred and thirty-one children completed the planned 12-week of follow-up using RUTF in this study, so they were included in the final analysis. Body weight increased significantly from baseline to 12-weeks after RUTF (6.8±1.7 kg vs. 7.6±1.2kg, p<0.0001). Likewise, MUAC also increased from baseline to 12 weeks after RUTF (116.0±9.1 mm vs. 127.2±8.2 mm, p<0.0001). Conclusion The RUTF was found to significantly improve weight gain and MUAC among children aged between six to 60 months with PCM during a period of 12-weeks. Early diagnosis and timely intervention can improve outcomes among children with PCM. Community-based interventions can be aimed to improve the nutritional status of children in a developing country like Pakistan.
The Effects of an Online–Offline Hybrid Exercise Program on the Lives of Children with Cerebral Palsy Using Wheelchairs during the COVID-19 Pandemic in Korea

Due to the ongoing COVID-19 pandemic, many online programs for social meetings, education, leisure, and physical activities have been developed and provided; however, children with cerebral palsy (CP) cannot enjoy online programs in the same way that those without disabilities can. The aim of this study was to investigate the differences in reintegration to normal living (RNL), social interaction, and quality of life among school-age children with CP after participation in a game-based online–offline hybrid group exercise program. The current study was conducted on 26 children with CP who participated in a hybrid exercise program. The RNL, social interaction, and quality of life were measured before and after the six-week program. The scores of RNL and quality of life were improved (p < 0.05) after program participation. Online or hybrid exercise programs incorporating interactive methods (i.e., competition and cooperating) could enhance RNL and quality of life of children with CP. Thus, well-designed online or hybrid exercise programs should be developed and provided for children with CP to enhance overall quality of life during the pandemic.
Long-Term Fertilization Alters Mycorrhizal Colonization Strategy in the Roots of Agrostis capillaris

Long-term fertilization targets mycorrhizal fungi adapted to symbiotic exchange of nutrients, thus restricting their colonization potential and re-orienting the colonization strategies. The MycoPatt tool has a high applicability in quantifying the symbiotic process with the identification of mycorrhizal indices and projection of mycorrhizal patterns. Organic treatments increase the symbiotic process, visible in values of colonization frequency and intensity, with about 6% more than the native status of colonization. At the opposite pole, organic-mineral treatments decrease the colonization parameters by up to half of the organic treatment. All of the colonization parameters show significant correlations, except for the arbuscules/vesicle ratio (0.03). All the applied treatments, except for the organic one, record multiple root segments with a colonization degree lower than 10%. The application of treatments changes the strategy of native colonization from a transfer (40%) and storage (37%) to a predominant storage (50%) for organic treatment, and are mainly proliferative between 38–50% in mixed and mineral treatments. The high amount of mineral components increases also the presence of resistance conditions strategies. The use of mycorrhizal pattern maps, with the inclusion of colonization strategies, presents an important direction in understanding the evolution of mutual relations, and to explore in-depth the efficiency of the whole symbiotic process.
