Initial designing a dual-band antenna baced on end-fed dipole-like radiators for digital antenna arrays
Authors: Alekseytsev S. A.
Published: February 2021

The paper deals with the designing of the initial arrangement for dual-band antennas comprising two parallel dipole-like radiators as the drivers for the mentioned antenna. The excitation of the drivers is provided by the source of the induced electromotive forces (EMF), whose outputs are attached to the remote terminals of the radiators. The paper also provides the key electrodynamic characteristics of the structure under research for the following procedure of multi-parametric nonlinear optimization. In addition, on the basis of the induced EMF method, has been obtained the expressions for the far-field zone (Fraunhofer zone) characteristics with taking into account the parasitic currents on the radiating bodies of the dipole, which allows more accurate design of the initial topology of the antenna.

Authors: Rubanov V. G. , Velichko D. V. , Bushuev D. A.
Published: February 2021

Purpose of research. The control object was considered to be a thermal unit in the form of a modified two-tier tunnel furnace designed for the production of foam glass blocks. The main goal of this work was to improve the quality of products, reduce defects, and ultimately increase productivity by developing an automated system for controlling the thermal field of a technological unit for the production of foam glass blocks using an adaptive three-position control law with adaptation to the load of the average position of the regulator. Methods. At the initial stage, a functional automation scheme for a modified two-tier tunnel furnace was developed. To model dynamic discrete systems, a mathematical apparatus was used in the form of labeled Petri nets, which resulted in algorithmization of the technological process for the production of foam glass blocks. This solution to the problem should be used as a method of algorithmization and programming of the logic controller that is part of the automation system structure. The developed functional automation scheme can be converted into a mnemonic circuit, thereby implementing a SCADA system designed for control and visualization, diagnostics and monitoring of the process at a centralized control point, which is part of the automated workplace of the operator-technologist. The described approach to the development of an automated process control system has a generalized representation. The solution is methodological in nature, demonstrating the usability of the model in the form of a labeled Petri net. Results. In the course of research, a graph of operations of the production process with discrete adaptive threeposition control of the average position under load was developed. To check the correctness of the graph of operations, a tree of achievable markings was built, and its analysis was performed for compliance with security conditions and network liveliness. A block diagram of the main algorithm and the algorithm for adapting the controller's control program is developed. Conclusion. The described approach to the development of an automated process control system for the production of foam glass blocks has a generalized character, although it is illustrated by applying it to a specific object , since it allows changing both the number of variables xi , zi, and their functional purpose, that is, instead of sensors, pushers, valves, parameter values, for example, temperature, other automation elements and other physical variables and their parameters can be used. Thus, the presented solution is methodological in nature, demonstrating the convenience of using the model in the form of a Petri net and a tree of achievable markings for algorithmization and programming of a logic controller that is part of the automation system structure.

Authors: Tseng Ling-Ming , Lien Pei-Ju , Huang Chen-Yu , Tsai Yi-Fang , Chao Ta-Chung , Huang Sheng-Miauh
Published: February 2021

Background

The pregnancy rate after cancer treatment for female survivors is lower than that of the general population. Future infertility is a significant concern for patients with breast cancer and is associated with a poor quality of life. Reproductive-age patients with breast cancer have safe options when choosing a type of fertility preservation method to be applied. Better information and support resources aimed at women to support their decision making are needed.

Objective

The objective of this study was to develop a web-based shared decision-making tool for helping patients with breast cancer make decisions on fertility preservation.

Methods

We used the action research cycle of observing, reflecting, planning, and acting to develop a web-based shared decision-making tool. The following four phrases were applied: (1) observe and reflect—collect and analyze the decision-making experiences of patients and health care providers; (2) reflect and plan—apply the initial results to create a paper design and modify the content; (3) plan and act—brainstorm about the web pages and modify the content; (4) act and observe—evaluate the effectiveness and refine the website’s shared decision-making tool. Interviews, group meetings, and constant dialogue were conducted between the various participants at each step. Effectiveness was evaluated using the Preparation for Decision-Making scale.

Results

Five major parts were developed with the use of the action research approach. The Introduction (part 1) describes the severity of cancer treatment and infertility. Options (part 2) provides the knowledge of fertility preservation. The shared decision-making tool was designed as a step-by-step process (part 3) that involves the comparison of options, patient values, and preferences; their knowledge regarding infertility and options; and reaching a collective decision. Resources (part 4) provides information on the hospitals that provide such services, and References (part 5) lists all the literature cited in the website. The results show the web-based shared decision-making meets both patients’ and health providers’ needs and helps reproductive-age patients with breast cancer make decisions about fertility preservation.

Conclusions

We have created the first web-based shared decision-making tool for making fertility preservation decisions in Taiwan. We believe female patients of reproductive age will find the tool useful and its use will become widespread, which should increase patient autonomy and improve communication about fertility preservation with clinicians.

Published: February 2021

The paper reports the study of the complex formation of cobalt (II) with diethylenetriaminepentaacetic acid (DTPA, H5L) based on spectrophotometric (SF) and potentiometric data (pH). Complexes of different compositions were found, and equilibrium constants, as well as the stability constants of these complexes, were determined. Accumulation of complexes in proportion is calculated based on the acidity of the medium. The experimental data have been carried out by using mathematical models to assess the solution's possible existence with a wide spectrum of complex particles and to point out those which are quite sufficient to copy the experimental data. In addition, thermodynamic parameters (ΔG°, ΔH°, and ΔS°) for the studying complexes were calculated according to the values of stability constant (KST) at 25 °C obtained from the temperature dependence of stability constant by using van’t Hoff equation.

Authors: Tyubee Bernard Tarza
Published: February 2021

The study estimated annual and temporal variation in per capita Land Use/Land Cover Change (LULCC) in Makurdi, Northcentral Nigeria. A total of four Landsat TM/ETM+ images were acquired in April of 1991, 1996, 2001 and 2006 for the study. A total of five LULC types namely water, forest, undergrowth/wetland, cultivated land and built-up land were derived from the Landsat images using supervised classification method. The per capita LULCC was derived by dividing the areas of LULC types by the actual population data. The result showed that built-up land recorded the highest long-term gain in area by 179km2 (130%), with an increment of 8.7% per anum, and undergrowth/wetland lost 119km2 (32%) in area with a decrease of 2.1% per annum from 1991 to 2006. The per capita LULCC of built-up land has increased from 575m2/person (1991) to 1059m2/person (2006), representing an increment of 481m2/person (83%). The undergrowth/wetland recorded the highest decrease in per capita LULCC from 1542m2/person (1991) to 836m2/person (2006), representing a decline by 706m2/person (46%). The study concludes that undergrowth/wetland is the most vulnerable LULC type due to urbanisation, and sustainable urban planning should be practised to conserve the natural cover materials in the study area.

Objective: Verrucae plantaris (VP) results from environmental exposure to human papillomavirus causing plantar warts of the foot, resistantto treatment, and high recurrence rates. Current treatment paradigms focus on the treatment of lesions as opposed to primary prophylaxis. Wehypothesize that a topical combination of herbal supplement with anti-viral properties and a vitamin derivative* can be used prophylactically todecrease the primary incidence.Methods: We initiated a double-blinded clinical study with participants (n=282) randomization into control (lotion emollient only) (n=120),treatment (herbal and vitamin derivative) (n=110) and no treatment (NT) (n=52). Participants underwent examination of the feet at baseline (0months) to exclude VP lesions and were randomized to receive a bottle containing topical lotion with emollient only, control (C), lotion with an herbaland vitamin derivative, treatment (T), or NT, where participants did not apply anything to their feet. C and T participants applied lotion topically to thefeet once daily and were examined at 3, 6, 9, and 12 months to document the incidence of VP.Results: No incidence of VP occurred in the T group (0/110=0% incidence), two lesions in the C group (2/120=1.7% incidence), and five lesions inthe NT group (5/52=9.6% incidence).Conclusion: Treatments for VP rely on treating lesions after they occur, have high degrees of variability in success, risk of continued transmissionduring treatment, and have high rates of recurrence. Although the study number is relatively low, early indications show decreasing incidence ofVP from 9.6% in participants with NT to 1.7% in participants who used lotion only, suggesting increased health of the plantar epidermis, and 0%incidence in those participants applying topical herbal and vitamin derivative*. Additional study with increased numbers of participants is warranted.

Development of nanomodified multifunctional protection systems for wood structures
Authors: Pokrovskaya Elena N.
Published: February 2021

Introduction. Nowadays multi-storey buildings, composed of wood structures, are built in different countries. The durabi-lity of structures depends to a large extent on the protection systems used. The most effective ones are multifunctional protection systems that rise the fire protection ability, hydrophobicity, and biostability of structural materials. The application of carbon nanotubes is expected to improve the uniformity of a protective layer and the coating performance. The purpose of the project is to develop a multifunctional protection system designated for wood structures. This system must ensure their fire resistance and hydrophobicity without deteriorating the mechanical properties of wood.

Materials and methods. Pine wood samples were used in the research. Carbon nanotubes were used as nano-modifiers. Wood samples, surface-modified with methylphosphonic (MPH) and nitrilo-trimethylphosphonic (NPH) acids, were used to develop multifunctional protection systems. Integrated protection systems were developed by adding carbon nanotubes. Fire hazard properties were assessed pursuant to GOST 27484-87, water absorption properties were analyzed pursuant to GOST 16483.20-72, mechanical properties were addressed with reference to GOST 16483.11-72 and 16483.10-73. Hydrophobicity was evaluated using the wetting angle method. The character of the sample surface and its chemical composition were studied using the double-beam scanning electron-ion microscope FEI Quanta 3D FEG with an EDAX Octane select attachment needed for the energy dispersion analysis.

Results. All studied coating systems belong to the first group of the fire retardant efficiency, the best of them reduce weight loss in the course of combustion of samples: Δweight = 3.7 – 1.34 %. Wood develops hydrophobic properties; its water absorption reduces 1.5-fold, while its across-fiber mechanical compressive strength goes up 1.6-fold. The assessment of the wood surface and its chemical composition shows that high fire resistance correlates with higher phosphorus content in the char layer formed during combustion.

Conclusions. Surface modification of wood by protection systems is recommended as an effective means of rising the durability of structures.

‘Escape rooms’ are a recent cultural phenomena, whereby a group of ‘players’, often friends or colleagues, are ‘locked’ in a room and must solve a series of clues, puzzles, or mysteries in order to ‘escape’. Escape rooms are increasingly appearing in a range of settings, including science centres and museums, libraries and university programmes, but what role can an escape room play in science communication? In this commentary, we explore the emerging literature on escape rooms as well as thoughts from a small number of escape room creators in the U.S. and U.K.

Published: February 2021

El artículo presenta un análisis de los sistemas de calidad que se han implantado en el campo de la fruticultura intensiva en la Región de Murcia. Siguiendo los clásicos análisis de Max Weber, se plantea entender el “espíritu” de la calidad como un nuevo avance del proceso de racionalización empresarial, con la constitución de una burocracia de la calidad como saber especializado requerido para cumplir con las normas de certificación. El ámbito geográfico de estudio es la Vega Alta del Río, una comarca que desde hace décadas ha venido introduciendo innovadoras transformaciones para asentar un complejo agroexportador de fruta y uva de mesa. La fundamentación metodológica del artículo es cualitativa. Por un lado, se presenta una historia de vida de un empresario pionero de la exportación de fruta en el municipio de Abarán.

Gangguan fungsi tiroid pada WUS akan meningkatkan risiko kehamilan dan berdampak negatif terhadap perkembangan anak. Tujuan. Penelitian ini untuk mengetahui hubungan kandungan iodium garam rumah tangga dan status iodium WUS di Kabupaten Wonogiri. Metode. Studi potong lintang dilakukan di Kabupaten Wonogiri. Total 170 responden wanita berusia 15-49 tahun, dilakukan pengukuran terhadap kandungan iodium garam rumah tangga, konsentrasi iodium urine (KIU), dan kadar thyroid stimulating hormone (TSH) serum. Analisis kandungan iodium garam rumah tangga dilakukan dengan metode titrasi iodometrik, KIU dengan metode ammonium persulfate digestion, dan kadar TSH serum dengan metode enzyme-linked immunosorbent assay (ELISA). Hasil. Analisis 170 sampel menunjukkan cakupan garam beriodium rumah tangga yang memadai yaitu 53,5 persen. Median KIU WUS 178,5 μg/L, dengan proporsi nilai KIU < 100 μg/L dan < 50 μg/L masing-masing 17,7 persen dan 7,1 persen. Kandungan iodium garam rumah tangga berhubungan bermakna dengan KIU WUS (p<0,05) dan tidak berhubungan bermakna dengan kadar TSH serum WUS (p>0,05). Kesimpulan. Cakupan garam beriodium tingkat rumah tangga di Kabupaten Wonogiri di bawah sasaran universal salt iodization (USI) (cakupan ≥ 90 persen). Nilai KIU < 100 μg/L dan < 50 μg/L masing-masing kurang dari 50 persen dan 20 persen, menunjukkan asupan iodium memadai.

Standardizing Sign-out With I-PASS Handoff in Family Medicine Residency
Authors: Sonoda Kento , Nakaishi Lindsay , Salter Cynthia
Published: February 2021

Introduction: Handoff miscommunications are a leading cause of medical errors. A structured handoff is an effective communication tool. We introduced the I-PASS Handoff Bundle for resident sign-out in the inpatient setting. We aimed to reduce preventable adverse events and unexpected floor calls while also improving residents’ confidence and preparedness to care for patients overnight.
Methods: We conducted an observational study at a single-site family medicine residency between April 2019 and March 2020. Residents received trainings in the I-PASS standardized handoff through didactic lectures and on-the-job sessions in September and November 2019. We evaluated the effectiveness of the I-PASS Handoff Bundle by comparing pre- and postimplementation data including number of medical errors and unexpected floor calls, along with residents’ reported levels of preparedness and confidence to care for patients overnight. 
Results: Prior to the I-PASS intervention, more than half of resident surveys included at least one unexpected floor call whereas postintervention about one-third of resident surveys included unexpected floor calls (P<.05). However, the intervention did not significantly affect residents’ confidence level in caring for patients overnight and residents’ rating of the usefulness of anticipatory guidance for managing night floor calls. We did not identify any medical errors related to communication issues at patient handoff within the family medicine service.     
Conclusion: I-PASS intervention significantly reduced unexpected floor calls. However, the intervention did not improve residents’ reported confidence and preparedness to care for patients overnight.

O presente estudo teve como objetivo analisar temáticas e métodos de pesquisa na produção de teses de doutorado em Gestão do Esporte em programas de pós-graduação de IES brasileiras. A pesquisa, de caráter exploratório, descritivo e abordagem mista, foi realizada através de revisão integrativa do tipo metodológica, considerando-se teses defendidas até 2019. Foram identificadas 94 teses, a partir de 1997, com distribuição geográfica desigual no país, majoritariamente produzidas em universidades públicas, em programas de Educação Física e Administração. As teses apresentam diversidade de temáticas, com predomínio de políticas públicas e lacunas quanto a outros temas de pesquisa. Revelaram-se aspectos críticos quanto à estrutura metodológica, com falta de informações quanto à abordagem e aos métodos de pesquisa e de análise. Conclui-se que o panorama da produção acadêmica sobre a área revela defasagens coerentes com as do desenvolvimento científico da área no país.
