Authors: Minuzzo Tainá
Published: May 2021

Megaesophagus is characterized by esophageal hypomotility associated with total or partial organ distension, which can be classified as congenital, acquired idiopathic, or acquired secondary. The pathogenesis of the congenital form is not well elucidated. However, the main clinical signs are reported after weaning with regurgitation, a delay in the puppy development and in the most severe cases, complications as aspiration pneumonia. The diagnosis is based on anamnesis, clinical examination, radiographs (simple and contrasted) and exclusion of secondary causes. Treatmentis based on nutrition management and resolution of secondary complications. Tthis paper aims to report the unusual case of a five-month-old pinscher dog, with signs of apathy, voracious appetite, regurgitation initiated after weaning and progressive weight loss. Due to the alterations simple and contrasted radiographs were performed, which showed megaesophagus. After excluding secondary causes, the diagnosis of congenital megaesophagus was confirmed. Therefore, food management was carried out to maintain caloric intake, with a pasty diet, five times a day, with the patient kept in a bipedal position during and after feeding.

Authors: Viryasov A. , Zlatkinа N. , Polonskaya H. , Arsenian A. , Sulikova R.
Published: May 2021

Summary. Urgency. In recent years, the concept of nursing process has been actively introduced. It is especially relevant in geriatric practice, where the issues of nursing prevail over those in young and middle age. There are forms of organization of care, where it is the average medical staff is leading in providing medical care (hospices, nursing hospitals, homes for the elderly, etc.). In these conditions, the nurses ' responsibility in making and implementing medical decisions in the event of emergency conditions increases.

Purpose of research. To substantiate and develop the principles of the organization of the nursing process in the event of emergency conditions in the elderly in combination with polymorbid pathology.

Method of research. The methods of statistical calculation were used: determination of the required number of observations (n), comparison of relative and average values using parametric correlation methods, as well as analytical and comparative analysis methods. A total of 1188 elderly patients with polymorbid pathology were examined.

Results. The main complaints of elderly patients presented by them at admission to the hospital were identified. The first six places were: General weakness 42.9%, abdominal pain 32.2%, shortness of breath 31.1%, nausea 19.6%, chest pain 18.1%, dry mouth 17.8%.

Complaints, which occurred in more than 5% of cases, were taken for the development and scientific justification of clinical and organizational algorithms of the nursing process in the event of emergency situations in the elderly and senile age which are based on symptoms.

Summary. The following principles should be implemented in the construction of a nursing diagnosis:

Completeness of examination. Nursing examination does not depend on the medical and can not be replaced by them, as before these examinations are different tasks. The task of the nursing examination is to collect information about the patient's health and its analysis.

Correctly collected anamnesis. The purpose of this principle is to find out the time of onset of the disease, the initial symptoms, their features, their dynamics, clarify existing diseases, risk factors, allergoanamnesis, in order to suggest tactics based on complaints and anamnesis data.

Consistent, detailed physical examination of the patient nurse conducts by examining and observing the patient, as well as conventional methods (eg, thermometry, measurement of blood PRESSURE, respiratory rate).

The principle of reasonable sufficiency should be observed in each case.

Authors: Gogushev K. , Valcheva Z.
Published: May 2021

All technologies and materials nowadays aim to ensure the elimination of pain, providing greater comfort and satisfaction for the patient. Research on patients' perceptions of the technologies used is gaining in popularity. The aim of this article is to study and compare the opinions of patients who have sought dental care to treat a defect in the dentition with restorations made using a conventional and digital impression. Materials and methods: The survey involved 116 patients who sought dental care in two private practices in Varna, Bulgaria. To achieve the goal of the survey, special questionnaires have been developed, in which there are two types of questions: with only one or more than one possible answer. Results: Most of the participants (81%) report that they have at least one extracted tooth, which is not a third molar (wisdom tooth). Patients over the age of 40 are more likely to have a missing tooth. Slightly more than 1/3 of the patients or 35% indicated impaired masticatory and aesthetic function. Most of the patients prefer a prosthetic treatment with a fixed restoration. On 76,7 % of the patients a conventional impression was taken during dental treatment and only 12 % report that they undergo a treatment with digital impressions. Conclusion: Our results show that males are at a higher risk for premature loss of permanent teeth than females. (OR=2.17 (0.830-5.654); p<0.05). The analysis of the discomfort of teeth loss according to gender revealed a significant difference in women and men (p <0.05), as women mostly experience discomfort from impaired aesthetic function, while in men the discomfort is associated with impaired masticatory and speech function.

Authors: Starostina S.
Published: May 2021

It is known that modern life requires more knowledge, and also complicates the content of the material that students master at school. Teaching traditionally, teachers note the difficulties with the development of the program material by the majority of students. This is due to the differences between students in the class in terms of potential, work rate, development, or differences in these indicators. The learning process is built by teachers, and the average student is chosen as a reference point, but the lagging or capable student does not receive enough attention. In this situation, students with high potential are not given a sufficient load, while for lagging students, learning is difficult. Therefore, the purpose of the study: to identify the pedagogical conditions of differentiation of students learning in the process of teaching mathematics in secondary school.

Analysis of coupling characteristics of coaxial line parallel to lightning current channel
Authors: Li Xiangchao , Chu Lei , Luo Hua , Wen Qiaoli , Ouyang Wen
Published: May 2021

Base on the analysis of the coaxial coupling theory, the experimental model of the coaxial cable short-range coupling lightning electromagnetic pulse is established to study the problem of coaxial cable short-range coupling lightning electromagnetic pulse on the ship mast and high tower. The combination wave generator is used to simulate the 8/20 μs lightning current waveform, and the metal bar with the length of 1 m and diameter of 0.016 m is used to simulate the lightning channel as the radiation source. The length of the coaxial cable and the distance from the radiation source are changed for the test. The conclusion is as follows: when the coaxial cable is coupled with lightning wave in a short distance, the voltage waveform of cable terminal is still double exponential wave, with strong damping oscillation at 0.1 ∼0.4 μs. When the cable terminal is open circuit or connected with matching resistance, the rising time is shorter, about 1 μs; when the cable terminal shielding layer is grounded, the rising time is longer, about 10 μs. The peak voltage and energy coupled to the coaxial cable at short distance are positively correlated with the cable length, and inversely correlated with the distance from the radiation source. The energy that the cable is coupled to mainly comes from the low-frequency part, and there are multiple energy peaks below 100 Hz. Using fitting curve and experimental data, when the coaxial cable terminal is open circuit, the lightning current reaches 30 kA, the cable length is 30 m, and the distance from the lightning channel is 0.15 m, the peak value of the voltage coupled to the cable terminal is 66 V. It has certain guiding significance and value in the practical application of electromagnetic pulse protection.

Authors: Swiatkowski Michal , Witczak Pawel
Published: May 2021

The aim of this paper is to present the impact of the leakage flux on magnetic shunts and tank walls of power transformers from vibrational point of view. The experimental studies of the large power transformers show that tank vibrations and the resulting acoustic emission at load condition are significantly higher than at no-load condition. The paper presents 3D finite elements model in electromagnetic domain used for the analysis of magnetic forces applied to shunts at rated short circuit state which are the origin of tank vibration. The main finding of the work is that forces equivalent to the magnetostriction deformation of the shunt interior are comparable with magnetic forces resulting from the stray field and applied to the shunts’ surface.

RESULTS:

A total of 1,156 and 1,378 transcripts were differentially expressed (DE) in two cultivars at white stage and red stage respectively. Among them, 28, 49 and 72 DE transcripts were involved in AsA, sugars metabolism and plant hormones signaling respectively. Fruits of ‘Benihoppe’ with higher anthocyanins content contained higher AsA, the expression of D-galacturonate reductase (GalUR) in white-fleshed strawberry was down-regulated. Particularly, the expression of transcripts involved in sugars, jasmonic acid (JA) and abscisic acid (ABA) signaling was decreased, by contrast, the expression of transcripts involved in auxin and gibberellins (GAs) signaling was significantly increased.

CONCLUSIONS:

The lower AsA level in white-fleshed strawberry is possibly because of the lower flux of D-galacturonate biosynthesis pathway. Anthocyanins was associated with gene expression involved in AsA, sugars, and hormones signaling metabolisms.

Underground coal mine operation should avoid overtime or continuous working hours too long, otherwise easy to increase fatigue, increase the physiological and psychological burden of operators, resulting in accidents. How to prevent operator fatigue and unsafe behavior is the focus of current research in the industry and academia. It is an effective means to reduce physical and mental injury and accident rate caused by bad working environment to pump station drivers through reasonable arrangement of working time. In this study, the field measured physiological index data of a mine face pump station driver in Henan province, China were taken as an example, and the sensitive physiological indexes such as systolic pressure, diastolic pressure and heart rate of the underground pump station driver were calculated by using the grey predictive model GM (1,1). The warning range of each index was determined, and the safe working hours of the pump station driver was predicted. The results show that, according to the principle of minimum value triggered by threshold value of physiological indexes, the reasonable safe working hours of pump station drivers in fully mechanized mining face is 5.7 hours. The conclusion shows that the quantitative study of safe working hours provides a reference for the reasonable arrangement of working time and has a certain guiding significance for the reduction of human error and safe production.

Recently, the Digital Twin (DT) technology, which joints the physical environment and virtual space, has drawn more attention in industry and research academic plans. In general, the virtual model representations of the physical objects are created in the DT manner to simulates the characteristics and behaviors of the real-word system. Applying a supervisory system not only can reduce the failures of components, but also preserve the overall costs associated with the system at a minimum. This paper reviews the DT applications in the power system, while its advantages in wind turbines, solar panels, power electronic converter, and shipboard electrical system will be briefly discussed. The potential benefits of contemporary technologies to ameliorate the DT in the industry are studied. Besides, it provides a great technique to assess and analyze system performance. As a basis for DT, various new emerging developments as an example of artificial intelligence (AI), big data, the internet of things (IoT), and 5 G are reviewed.
State of health estimation and remaining useful life prediction for lithium-ion batteries using FBELNN and RCMNN
Authors: Lin Qiongbin , Xu Zhifan , Lin Chih-Min
Published: May 2021

This study proposes the novel method of lithium-ion battery state of health (SoH) estimation and remaining useful life (RUL) prediction to ensure the safety and reliability of the energy storage system. A fuzzy brain emotional learning neural network (FBELNN) is employed to estimate SoH and a recurrent cerebellar model neural network (RCMNN) is used for the RUL prediction. The inputs of FBELNN are extracted features from the monitoring curve of the constant voltage and current, because the lithium-ion battery is seldom completely discharged and the discharging situation in actual operating process is complex. The FBELNN learns the battery aging features that are extracted and selected by discrete wavelet transform and principal component analysis, respectively. The SoH estimation results from the FBELNN are accurate due to the special structure and parameters adaptive laws. The RCMNN and online training again can improve the performance of RUL prediction, because recurrent units can capture the dynamic features. Experimental data are performed by using NASA Prognostics Center of Excellence battery datasets to verify the effectiveness of the proposed method. The results show that the root mean square error of SoH estimation is smaller by the FBELNN and the prediction accuracy of RUL is higher by RCMNN under the different starting points.

Availability of massive amounts of data is a key contributing factor that influences the performance of deep learning models. Convolutional Neural Networks for instance, require large amounts of data in different variations to enable them generalize well to viewpoints. However, in health and other application domains, data generation and processing tasks are time-consuming and requires annotation by experts. Capsule Network (CapsNet) have been proposed to curtail the limitations of Convolutional Neural Networks (CNNs). Due to the problem of crowding, capsule Networks perform badly on complex and real-life images such as CIFAR 10 and some medical images. In this study, a variant of a capsule network with a new algorithm referred to as the amplifier and a new squash function termed exponential squash is proposed. The amplifier is implemented in the encoder network to improve the texture of the images and has the ability to assign low relevance to irrelevant features and high relevance to vital features. The exponential squash function reduces the coupling strength of unrelated capsules in the lower and upper capsule layer. The proposed algorithm was evaluated on four datasets; CIFAR 10, fashion-MNIST, eye disease dataset and ODIR dataset achieving accuracies of 84.56% 93.76%, 89.02% and 87.27% respectively. This work sheds light on the possibility of applying CapsNet on complex real-world tasks. The proposed model can serve as an intelligent tool to aid medical personnel to diagnose eye disease and apply the necessary treatments.

Published: May 2021

Complex fuzzy aggregation operation (CFAO) is a formalized definition of combining several complex fuzzy sets into a single complex fuzzy set. It extends classical fuzzy aggregation operation (FAO) to the complex-valued domain retaining classical real-valued weight. CFAO was initially defined with complex weight by Ramot et al. However, there has been virtually no progress in developing CFAO with complex weight. In this paper, we study the CFAOs with complex weight. We first discuss how to define complex weights meeting the restriction that the sum of weights is equal to 1. We give a new natural type of complex weight which is different from Ramot et al.’s complex weight. Then we study various properties which include idempotency, homogeneity, rotational invariance and shift invariance for CFAOs with both types of complex weights.

Authors: Zhang Yang , Ye Jianmu
Published: May 2021

This paper takes the listed pharmaceutical manufacturing firms in China’s A-share market from 2011 to 2017 as the research sample, from the perspective of top managers’ pay gap, employs principal component analysis and general least square method to empirically investigate the effect of risk preference of top management team(TMT) on the re-innovation behavior after the failure of innovation. The study found that the risk preference of TMT is positively correlated with the re-innovation input and brand-new innovation after the failure of innovation, but not with the supplementary innovation. Besides, the pay gap not only has a positive moderating effect on the positive correlation between the risk preference of TMT and the re-innovation input, but also on the positive correlation between the risk preference of TMT and the brand-new innovation after the failure of innovation. The findings of this study contribute to: (1) through empirical research on the impact of TMT risk preference on re-innovation behavior after innovation failure, expand the relevant research content and research methods of TMT and innovation failure to make the research results more convincing; (2) by setting a reasonable executive compensation gap, TMT can avoid blindly choosing brand-new innovation behavior after innovation failure with the increase of risk preference innovation, ignoring the potential value of innovation failure projects without supplementary innovation, improving the re-innovation behavior of TMT after innovation failure and improving the re innovation success rate after innovation failure.

Authors: Lei Shi
Published: May 2021

An improved Web community discovery algorithm is proposed in this paper based on the attraction between Web pages to effectively reduce the complexity of Web community discovery. The proposed algorithm treats each Web page in the Web pages collection as an individual with attraction based on the theory of universal gravitation, elaborates the discovery and evolution process of Web community from a Web page in the Web pages collection, defines the priority rules of Web community size and Web page similarity, and gives the calculation formula of the change in Web page similarity. Finally, an experimental platform is built to analyze the specific discovery process of the Web community in detail, and the changes in cumulative distribution of Web page similarity are discussed. The results show that the change in the similarity of a new page satisfies the power-law distribution, and the similarity of a new page is proportional to the size of Web community that the new page chooses to join.
