Published: November 2021

The relational model in which all data accessible to the user, is organised in the form of tables is put in a basis of construction of a database of optoelectronic means, and all operations over the data are reduced to operations over these tables. In a database the technology «client-server» is used. As the server of a control system database chooses relational system Firebird. Advantages given system database concern: the minimal requirements to the equipment, a wide spectrum a component and drivers for various environments of working out, possibility of service of the big databases and a great number of users. Such structure of construction of a database allows as to expand the list хранимой in it information without change of a code of the program, and not to limit subject domain only to the set groups of optoelectronic means. The structure of a relational automated database of optoelectronic devices (OED) is described, which allows you to store and change information about OED if necessary, select them in accordance with specified criteria, and conduct problem-oriented statistical processing of data on optoelectronic devices.
Quaternion domain Laplace transform of the pulse vector
Authors: Sovetov V.M.
Published: November 2021

The Laplace transform (LT) is widely used in radio engineering for signal and circuit analysis. The PL greatly facilitates the solution of differential equations, the calculation of transfer functions, the finding of impulse responses, etc. Multiple-Input Multiple-Output (MIMO) systems are becoming more common today. With input influences on such systems, at the output signals are obtained, the elements of which are closely related to each other, and changes in some influencing elements of the input vector change the values of others. Such changes are usually associated with the preservation of the vector norm during transformation. Obviously, this completely changes the shape of the output response and, accordingly, its spectrum. To calculate such changes, it is possible to use the usual PL of real signals and the corresponding theorems. However, this approach requires a significant investment of time and computational resources. If you change the amplitude, shape, time shift of at least one pulse, you will have to repeat all the calculations again. Quaternion transformations, including the Laplace transform, have been studied in many works. However, these studies are often of a general theoretical nature or are used only to obtain the Fractional Quaternion Laplace Transform of 2D images. To calculate the LT of the impulse vector when using the MIMO scheme, it is proposed to use hypercomplex numbers, in the particular case, quaternions. Quaternion is a hypercomplex number with one scalar and three imaginary numbers i, j, k. To get rid of operations with imaginary numbers, the quaternion is represented as an orthogonal 4×4 matrix. The matrix, in turn, is decomposed into 4 basis matrices. Moreover, operations with matrices correspond to operations with imaginary units and the quaternion as a whole. It is shown that the quaternionic Laplace transform (QLT) of the vector is represented as a one-dimensional integral from 0 to ∞ of the vector. In this case, the matrix exponent in the power of the quaternion frequency matrix S = Eσ + 1/√3(I + J + K)ω is used as the transformation kernel, where E, I, J, K are basis matrices. The main properties of the QLT are considered. It is shown that in terms of the notation form, the properties of the QLT correspond to the properties of the LT of real functions, taking into account the non-commutativity of matrix multiplication. Therefore, to calculate the QLT, it is possible to use the well-known expressions for the LT of real pulses with the replacement of the complex frequency s by the matrix of quaternion frequencies S. Expressions for the QLT are obtained for the pulse vectors, which are often used to solve radio engineering problems. It is shown that for σ = 0 these expressions correspond to the quaternionic Fourier transform of the vector pulses. In general, vector pulses can have different delays, amplitudes and shapes. Expressions are obtained for finding the QLT of such vectors.

Authors: Popov O.V. , Tumashov A.V. , Borisov G.N.
Published: November 2021

Existing software tools such as Altair FEKO, Ansys HFSS do not allow correct optimization of asymmetrical vibrators, the design of which includes grounding and counterweights. Meanwhile, counterweights often have large dimensions and high cost, comparable to the cost of antenna radiating elements. These circumstances make the development of a method for calculating the input impedance of an asymmetrical vibrator with a partially recessed base urgent. The proposed method for calculating the input resistance was built in the electrostatic approximation, which made it possible to exclude the radiation resistance from the calculation, leaving only heat losses in the underlying surface. The combination of the mirror image method and the average potential method allows one to take into account the influence of the interface between the media. The calculations performed using the developed technique allow making recommendations for determining the grounding depth and the need to install counterweights, depending on the type of soil and the electric length of the vibrator

Published: November 2021

In the article, based on the mathematical apparatus of the statistical theory of optimal control in the state space, the synthesis of a method for controlling the parameters of the pulse-Doppler onboard radar system (BRLS) of a fighter aircraft is presented, in the interests of ensuring the energy stealth of its operation on radiation with a given probability, when detecting an air target-the carrier of a radio intelligence station, the optimal minimum local quality functional. The efficiency of the synthesized method is also evaluated on the basis of modeling. As part of the synthesis, the quality functional was determined and control signals were obtained for the parameters of the radar operation, which make it possible to ensure the energy stealth of the fighter's radar operation with a given probability in the process of approaching the radar carriers and the radio intelligence station (RTR). The indicators of the control signal efficiency determine the probability of correct detection of the radar of the air target carrier of the RTR station and the probability of non-detection by the RTR station of the sounding radar signal in the process of their approach. Based on the simulation, the effectiveness of the control signals is evaluated, which shows that in the process of approaching the fighter and the RTR carrier station, the energy stealth of the radar operation is provided with a given probability by controlling the parameters of the radar operation.

The research presented here has been conducted in the Smart Charge project. It has addressed the use of renewables, e-mobility and battery charging in the Arctic as part of an effort to solicit fossil-fuelled alternatives. Of particular interest has been to determine what impact and support electric snowmobiles can provide together with local, renewable energy production. The relevance of vehicle-togrid/ building (V2G/B) solutions have been investigated in the project too. The idea has been to use electric snowmobiles for load shaving during extensive periods of the year. The research has looked at cost aspects, value stacking, climate impact as well as aggregated effects of controlled fleet management of idle snowmobiles. A case study undertaken at Longyearbyen at Svalbard, Norway has provided the most important empirical basis for the research presented. The research concludes that electric snowmobiles can have a positive effect on the local energy system and despite limited range can be quite attractive for the individual to operate if energy for charging is based on local driving solar power.

On Dolly and the scandalous nature of life sciences and Where bioethics really begins
Authors: Becker Gregor
Published: November 2021

25 years ago, Dolly the sheep and the cloning issue stood in the focus of widespread and heated societal and ethical discussions that, for the bigger part, were not rational. In the aftermath of Dolly, in Europe bioethics was established as a discipline that is hyper-sceptical critic of science. Bioethics seen from the point of view of science is nebulous to many researchers, such as Lewis Wolpert, who called bioethics "a gross load of nonsense". It appears that the image of science in bioethics and society has as much suffered and moved away from the factual truth, as the image of bioethics and society has suffered in science since the Dolly event. It is time to return to a reasonable view of science, bioethics and society - and of Dolly the sheep.

Authors: Nafei Zahra , Zare Elahe , Sadeghieh Tahereh
Published: November 2021

Background: Anxiety, depression, and stress during the pregnancy period are usually overlooked in women despite their detrimental effects on the mother and infant. Studies have shown an increase in the risk of behavioral and psychological problems in an infant's life because of the mother's exposure to negative excitement and stress before childbirth. In the present study, we aimed to assess the effect of maternal anxiety, depression, and stress during pregnancy on neonatal growth indices at birth.
Methods: This longitudinal survey was done on 102 pregnant women referred to the obstetrics clinic of Shahid Sadoughi Hospital of Yazd for prenatal care from September 2019 to March 2020. They were asked to fulfill two questionnaires related to the study. After delivery, the further information and growth indices of neonates were extracted by telephone.
Results: Regardless of the severity of depression, anxiety, and stress, a significant relationship was found between maternal age and stress (P= 0.033), so in mothers with younger age, pregnancy stress was more. Moreover, the study showed a significant relationship between height and maternal anxiety (P = 0.018).
Conclusion: Based on the findings of this study and due to the possible association of neonatal indices with maternal anxiety, depression, and stress during pregnancy, more attention to maternal emotional health seems necessary.

Background: Retinopathy of prematurity (ROP) is an important cause of preventable blindness in children. The aim of this study was to examine the association of the polymorphisms at Factor V Leiden (FVL) and methylene tetrahydrofolate reductase (MTHFR) gene with risk of ROP.
Methods: A total of 106 neonates with ROP and 110 healthy neonates were enrolled. The FVL G1691A and MTHFR C677T and A1298C polymorphisms were genotyped by PCR-RFLP assay.
Results: There was a significant association between FVL G1691A polymorphism and an increased risk of ROP. However, the MTHFR C677T and A1298C polymorphisms were not associated with risk of ROP.
Conclusion: FVL G1691A polymorphism may be risk factor for development of ROP in neonates. However, there was no significant association between MTHFR C677T and A1298C polymorphisms and risk of ROP. However, it is critical that larger and well-designed studies in different ethnicities are needed to confirm our conclusions.

Breast cancer has been diagnosed in majority of women worldwide over the years. It is a universal disease affecting people regardless of race, socio-economic status or culture. Delayed screening, examination and diagnosis can affect the impact of treatment and diagnosis. The objective of the study was to determine the influence of knowledge, attitudes and practices on adoption of early screening of breast cancer among women. The study employed cross-sectional and descriptive research design. A sample size of 384 households was used to obtain data from the households. The study targeted women aged 18-65 years. Sampling technique comprised of multistage sampling for the household, Quota sampling for the Focus Group Discussions and purposive sampling for the Key Informants. Primary data was gathered by use of questionnaires, Key Informant Interview guides, observation and Focus Group Discussions while secondary data was acquired through publications, journals, and internet access. All quantitative data were analysed using Microsoft excel, and Statistical package for Social Scientist (SPSS) version 20.0. The results from a Pearson chi square analysis with P>0.05 showed that knowledge on various risks to breast cancer significantly influenced the need for early adoption of screening; attitudes like curability of BCA, willingness to undertake BCA and if early detection of BCA is helpful were statistically insignificant in influencing BCA screening uptake with P>0.05, While findings indicate that there was no statistical significance between various practices and adoption of early detection of BCA in Homa Bay County. This indicated that most of the decisions to undertake early screening of breast cancer among women was less informed by their attitudes; while Practices among women indicated no statistical significance to adoption of early detection of BCA at a p>0.05. There is need for concerted public health awareness campaign on breast cancer early detection advantages in the community and by the Community Health Volunteers to encourage majority into the practice.

The paper examines the influence of the increased content of silicon and carbon on the tribotechnical characteristics, structure and phase composition of a new Co–Cr–W–C system wear-resistant alloy. It was found that a joint increase in the content of silicon and carbon (despite the increase in the friction coefficient) leads to a significant decrease in the values of the wear intensity and linear wear. This is associated with the formation of a dense homogeneous oxide film. It is shown that joint doping with silicon and carbon to the upper doping limit provides a slight decrease in weight gain at temperature of 1100 °C.

Published: November 2021

Recently, utilization of biological adsorbents plays an important role in the removal of toxic dyes such as Eriochrome Black T (EBT) azo-dye as they are considered as being produced from natural renewable source, easy availability, low cost, and being environmentally friendly. In this study, vermicompost (VC) was utilized to remove Eriochrome Black T (EBT) azo-dye from aqueous solution along ultrasonic ultrasonic-assisted adsorption. The parameters such as pH, adsorbent amount, operating time, and initial EBT concentration were investigated. The highest adsorption capacity was obtained as 50.64 (mg-EBT g-1-VC) at the pH of value of 2 after 2 minutes of ultrasonic adsorption. Pseudo first order kinetic model fitted very well with the experimental data (R2=0.9824). The determination coefficient of Temkin isotherm model (R2=0.8659) revealed that suggested model was compatible to experimental results. The results suggested that ultrasonic assisted adsorption of EBT onto VC could be cost- and time-efficient. Besides, the Scanning Electron Microscopy (SEM) analysis of adsorbent identified the surface structure morphology of VC. Moreover, functional groups of VC were detected after and before the ultrasonic-assisted adsorption by using Fourier Transform Infrared Spectroscopy (FTIR). Thus, interaction mechanism between VC and EBT were determined.

Published: November 2021

Transmissible Venereal Tumor (TVT) is one of the most uncontrolled spreading tumor via mating between dogs observed in both sexes. The clinical findings are less remarkable and are usually located in the caudal part of the penis and may include preputial discharge, licking of the region, dysuria, phimosis or paraphimosis (occasionally). In this study, the incidence of TVT and the relations of tumor with some factors were investigated in 145 male dogs, in Eskiºehir, Turkey. TVT’s diagnosis was based on location of the tumor mass and mainly exfoliative cytological findings. Smears of caudal part of the penis were painted with Giemsa staining method. The cells in the smears were identified as typical transmissible venereal tumor cells, polymorphnuclear leukocytes (PMN), erythrocyte, parabasal, intermediate, nucleated and anuclear superficial cells. In exfoliative cytological examinations, TVT cells were observed in the smears of 17 dogs (11,72 %), but only four of them (2,76 %) had TVT lesions clinically. Thirteen (8,97 %) of dogs had TVT cells but not having TVT lesions . It was found that the ages, weights and breeds of dogs had no effect on the TVT lesions and TVT cells. TVT positive animals were determined to have more erythrocyte and intermediate density than negatives and no association with other cells were found. PMNs were significantly different and high in the TVT cell positive cases compared to the negatives. In dogs with negative TVT cells, parabasal, intermediate, nuclear/anuclear superficial cells were more than those positives. As a result, the male dogs having no lesions could be infected with TVT. Dogs should be examined not only clinically, but also cytologically, to determine whether TVT cells are present. This method can be an easy way to find and treat TVT lesion-free but infected dogs at an early time.

Published: November 2021

Background: Turmeric is an age old herbaceous plant belonging to the family Zingiberaceae growing in Tropical Africa and India with huge national and international demands. Conventionally, turmeric accessions are characterized using morphological and agronomical traits but less work is done in molecular characterization which is needed for thorough trait identification. Methods: The investigation was carried out during Kharif 2016-17 and comprised of thirty diverse genotypes of turmeric analyzed for genetic variability and molecular diversity which were evaluated in randomized block design with two replications. Fresh tender leaves were used to isolate DNA and PCR was performed with 9 SSR markers. Result: The values of phenotypic coefficient of variation were slightly higher than genotypic coefficient of variation. Highest heritability was observed for days to maturity, genetic advance was observed highest for green rhizome yield. Out of 9 SSR markers, primer pair 5, 6, 7, 8 and 9 were reported to exhibit 100% polymorphism, whereas; in terms of PIC, primer pairs 6 and 9 were found to be highly efficient ones. The similarity coefficient ranged from 0.44 to 1.00 and dendogram categorized the 30 genotypes into two main clusters.

This study aimed to investigate perfectionism among talented students and its relationship to their self-esteem. Eighty-nine male and female talented students in King Abdullah II Schools for Excellence in Jordan were administered. Big Three Perfectionism Scale and Self-Esteem Scale to Rosenberg were used based on arithmetic mean, standard deviations, T-test for independent samples and Pearson correlation. The results indicate that the levels of three types of perfectionism and self-esteem are medium among students of King Abdullah II Schools for Excellence; also, there are no statistically significant differences between male and female students on Rigid Perfectionism and Narcissistic Perfectionism, while there are statistically significant differences between male and female students in Self-Critical Perfectionism and there are no statistically significant differences for Pearson Correlation to Rigid Perfectionism and Narcissistic Perfectionism on self-esteem; however, there are negative statistically significant differences for Pearson Correlation to Self-critical Perfectionism on self-esteem.

Keywords: Perfectionism, self-esteem, talented students.

At present Latvian education system is implementing a shift towards competency-based learning to improve the quality of education. Teachers are the agents of this change, therefore, a question of ensuring the transfer of educational experiences is becoming increasingly important. The aim of the research is to explore the importance of attitude as one of the factors of teacher’s professional competence and interrelationships between the transformative aspects of the acquired educational experience and personal and professional growth of the individual. A survey research design and a qualitative survey data analysis was employed. 530 respondents from different ethnical and professional backgrounds (Latvia, UK, and RSA) were selected using non-probability sampling, allowing gathering data on their educational journey and experience transfer. The outcomes demonstrate the link between the teacher’s example and attitude and the learner’s personal and professional growth, as well as shows the long-term emotional impact.

Background: This article explores the use of a mixed-methods participatory approach to bring about transformative change to goal setting in an 18-bed, subacute rehabilitation unit in New South Wales. Aim: To use a blended approach underpinned by practice development and appreciative inquiry approaches, to develop and evaluate a model of person-centred goal setting for rehabilitation clients. Methods: Evaluative methods were co-designed and co-agreed by members of the rehabilitation team, based on what the team hoped to achieve in terms of establishing goals for clients in their care and what this meant to clients and each other. Data sources included team discussions, semi-structured interviews with individual team members and clients, a survey and stories using emotional touchpoints. Interpretation of the data involved content analysis for generation of themes and the use of Statistical Package for Social Science software for analysis of the survey. Results: Nine themes emerged. Clients highlighted: barriers to goal achievement; incorporation of goals into daily care; goal achievement; and a sense of purpose. The rehabilitation team highlighted: becoming person-centred; their role in goal setting; and barriers to establishing goals. The survey responses showed the team used person-centred approaches to achieve person-centred goals. Conclusion: Changes to goal setting allowed staff to feel person-centred in their care delivery and gave them the satisfaction of knowing they were doing something meaningful for those in their care. There was strong agreement that a unified team approach to goal setting was key to client satisfaction and achievement of the goals. Clients felt valued and included in making decisions surrounding their care. Implications for practice: • Using the practice development principle of developing collaborative partnerships among healthcare teams leads to greater involvement of clients in their care • Involving clients in goal setting leads to greater success and improved client satisfaction • Appreciative inquiry and practice development approaches are effective in developing partnerships between team members • Staff who treat clients with dignity and respect improve participation in goal setting by the clients • Creating a space in which the emotional needs of clients can be heard and acted on is crucial for success in goal achievement • Appreciative inquiry generates a greater appreciation and understanding of how to deliver person-centred care

Background: Ethics is a difficult subject for nursing students to grasp and learn but, like person-centredness, it has an important role in the relationship between nurses and patients. Simulation has been found to be a suitable method for learning nursing procedures and actions, and the researchers wanted to explore whether it could be a suitable learning strategy for acquiring ethical skills, which are a prerequisite for delivering person-centred care. Aim: In response to the research question How can nursing students develop ethical competence through simulation? the study sought to consider how students could learn ethical reflection and decision making through simulated ethical dilemmas, and whether this could enhance their ability to deliver person-centred care. Design: The study was qualitative and exploratory, and based on students acting in scenarios representing general ethical dilemmas in nursing. There were four focus group interviews with nine nursing students in their second year, during their clinical practice. Students were recruited by self-selection. Data were transcribed and analysed using Graneheim and Lundman’s content analysis. Findings: The students gained experience through participation and acting in simulation exercises. The shared experience was a good starting point for guided reflection on ethical and tacit knowledge, and the acquired experience led to knowledge that is transferable to similar situations in clinical practice. Conclusion: This study shows that simulation is a valuable method for learning ethical reflection in nursing education. It found simulation to be suitable for developing ethical awareness that helps prepare nursing students to deliver person-centred practice. It has become a permanent learning strategy within nursing training at Nord University. Implications for practice: • Nursing students benefit from learning to practise critical ethical thinking as early as possible in order to become ethically aware and reflective during their training and later as nurses • Simulation is a valuable way to practise personal relationships with patients and colleagues • Simulated clinical scenarios improve competence in critical thinking and ethical conduct, and help prepare nurses to deliver person-centred practice. They can be used in all healthcare settings.
Book Review: Fundamentals of Person-Centred Healthcare Practice

When the right team comes together, the results are magical! This is exactly what happened when the authors of Fundamentals of Person-Centred Healthcare Practice united to write this book. Each contributing author interposes theoretical and practice expertise, all adding to the value and wisdom this work has to offer. The book sets out to guide us towards a shared understanding and a common language for person-centredness. The lens of the Person-centred Practice Framework offers an insight into its application in a number of areas of health and social care practice, while reminding us that all persons are ever changing. We are invited to remain open to change and to challenge ourselves and our beliefs as we embark on a journey into person-centred healthcare practice. As that journey begins, we are directed to explore various concepts, from what it means to be a person to the values of person-centredness, knowing self and flourishing as humans. Being person-centred requires a commitment to communicating clearly, navigating systems, appreciating contexts and engaging while being sympathetically present. The delineation of concepts in this book prepares us to explore chapters covering person-centredness in settings such as rehabilitation, long-term care, mental health and maternity services. The book is a call to action guided by approaches to learning and development that include active and reflective learning and critical thinking, alongside the strategies needed to create person-centred learning cultures.
