Peculiarities of the Norton conversions application when matching impedances with different transformation coefficients
Authors: Baranov Aleksander V.
Published: June 2022

The paper studies the features and consequences of the use of Norton conversions in the process of broadband and narrowband matching of circuit impedances based on filter theory in cases with different transformation ratios. For Norton circuits conversions with different transformation ratios (greater than and less than one), an additional rule is formulated. Using the generalized form of recording the Norton consequence conversions, two examples of reducing the number of elements in bandpass filters are demonstrated. In addition, the consequences that are characteristic of narrow-band applications of transformations are established. Formulas for calculating transformation ratios that depend on frequency are obtained for direct and mirror Г-shaped circuits with different reactivities. It is shown that these circuits can be combined with similar reactivities of Г-shaped circuits with frequency independent transformation ratios. On the basis of the established for the Norton conversions consequences, the step-up and step-down matching circuits of the combined type are synthesized.

Published: June 2022

In this work we calculated the reflection coefficients modules of a linear polarization plane electromagnetic wave depending on soil moisture with a relative complex dielectric constant described by the heterogeneous Maxwell Garnett and Bruggeman models. A comparison is made of the calculated dependences of reflection coefficients for incident E- and H-polarization waves on soil moisture according to the two proposed heterogeneous two-component models. The correctness of the applied models is shown within the soil moisture content up to 10 %. Within the limits of soil moisture change from 10 to 50 %, there are slight discrepancies in the calculation results for two heterogeneous models. The reflection level of an electromagnetic wave from the soil surface in the case of its H-polarization is less than in the case of E-polarization. With an increase in soil moisture, a monotonous increase in the reflection level is observed. The proposed heterogeneous models of wet soil and the calculation method can be used for remote radar sensing of the Earths surface in order to determine the moisture content in the rooted layer of the soil.
Comparison of the main aspects of modern approaches to the development of surface acoustic wave filters: model of the coupling of mode and the finite element method
Authors: Koigerov Aleksey S.
Published: June 2022

This article discusses the main issues of designing filters based on surface acoustic waves. A type of band-pass filter based on longitudinal resonant modes is presented. The features of the calculation based on two approaches are considered: the coupled mode model and the finite element method. Practical recommendations are proposed for reducing the time of filter calculation in numerical simulation. The results of calculating and measuring the transmission coefficient of a filter on a leaky surface acoustic waves on a 36 YX-cut lithium tantalate substrate are presented and compared. The main aspects and directions in which the considered modeling methods can be compared are highlighted and analyzed. It is shown that the use of different modeling approaches increases the development efficiency, and fast analytical models are required for the synthesis and optimization of filter parameters.

Authors: Golovkov Alexander A. , Golovkov Vladimir A.
Published: June 2022

Introduction: the analysis of the known literature shows that the use of various types of matching quadripoles (reactive, resistive, complex, mixed) and the feedback circuit covering the non-linear element makes it possible to increase the area of physical feasibility of the given forms of frequency characteristics. The purpose of the work is to increase the area of physical feasibility of given forms of frequency responses by optimizing the parameters of matching mixed quadripoles and using an additional feedback circuit covering a nonlinear element and a mixed quadripole. One part of such quadripoles consists only of resistive elements, and the second only of reactive elements. Materials and methods: theory of four-terminal networks, matrix algebra, decomposition method, method of synthesis of microwave control devices, circuit engineering method for analyzing the characteristics of radio devices. Results: Mathematical models of matching mixed quadripoles are obtained in the form of relationships between the elements of their transmission matrix and the dependences of the resistances of their two-terminals on frequency, which are optimal in terms of the criterion for providing specified forms of frequency characteristics. Conclusion: a comparative analysis of the theoretical results (frequency response and phase response of amplifiers) obtained by mathematical modeling in the MathCad system and experimental results obtained by circuit simulation in the OrCad and MicroCap systems shows their satisfactory agreement.
Description of digital systems by various construction schemes
Authors: Mishin Dmitry V. , Tyazhev Anatoly I.
Published: June 2022

The article discusses ways of describing digital systems with various schemes, provides a comparative characteristic of these schemes, indicates the advantages and disadvantages of different schemes. The four schemes for constructing digital systems described in the article are equivalent, since with the same input signal, the output signal for all circuits will be the same, although different signals will circulate inside these circuits. To build adaptive digital systems, preference should be given to state-space circuits, since in them it is easier to adjust the parameters of the digital system. When choosing between serial and parallel circuits, preference should be given to the parallel circuit if the coefficients in it are valid. With complex coefficients, the implementation of the parallel scheme becomes more complicated, therefore, in this case, one should choose a sequential scheme in the state space, all the coefficients are real.

Authors: Eliseev Sergey N. , Filimonova Lyudmila N.
Published: June 2022

In this paper, we consider the negative simultaneous effect of fast relay fading in the channel and mutual frequency shifts of subcarriers between the transmitting and receiving sides of the channel, causing violation of orthogonality between the signals of individual subchannels of OFDM system. Violation of orthogonality is manifested in the appearance of mutual interference signal at the receiving end of the channel in each OFDM subchannel. The paper evaluates the joint effect of fast fading and frequency shifts on the magnitude of the transient interference between subchannels and investigates in sufficient detail the manifestation of transient interference between individual subchannels caused by orthogonality violations each of the two factors cited separately. In this paper, we consider the simultaneous effect of both factors and their influence on the value of the interchannel transient interference.

Published: June 2022

Background: In current practice, establishing the potential predictors of high thrombus burden (HTB) before primary percutaneous coronary intervention (PCI) is crucial for its management. In this research, we aimed to investigate the association between vitamin D levels and HTB in patients with ST-elevation myocardial infarction (STEMI).
Methods: This prospective, observational study was conducted on 257 STEMI patients undergoing primary PCI in Van Education and Research Hospital between March 2020 and March 2021. The thrombus burden grade was determined for each subject. The study population was divided into 2 groups: patients with HTB and those with low thrombus burden (LTB) based on the thrombus burden grade. Demographic, laboratory, and angiographic features were compared between the groups.
Results: In total, 154 patients (mean age±SD=63.42±11.53 y, 65.6% male) had HTB and 103 patients had LTB (mean age±SD=61.50±10.23 y, 70.9% male). The patients stratified into the HTB group had lower vitamin D levels than those in the LTB group (8.0 ng/mL vs 17.9 ng/mL, respectively; P<0.001). The patients with HTB and low vitamin D levels had lower post-PCI thrombolysis in myocardial infarction (TIMI) flow, TIMI myocardial perfusion grade, and post-PCI ST resolution. In a multivariable analysis, vitamin D was an independent predictor of HTB among the STEMI patients (OR: 0.76, 95%CI: 0.70–0.82; P<0.001). The ideal value of vitamin D to predict HTB was >17.6 ng/mL with a sensitivity of 81.8% and a specificity of 90.3%.
Conclusion: The study results showed that vitamin D levels were an independent predictor of HTB in STEMI patients treated by primary PCI.

Published: June 2022

Background: Current evidence shows inequality in the outcomes of rural and urban patients treated at their place of residence. This study compared in-hospital mortality between rural and urban patients with acute coronary syndrome (ACS) to find whether there were differences in the outcome and received treatment.
Methods: Between May 2007 and January 2018, patients admitted with ACS were included. The patients’ demographic, clinical, and laboratory data, as well as their in-hospital medical courses, were recorded. The association between place of residence (rural/urban) and in-hospital mortality due to ACS was evaluated using logistic regression adjusted for potential confounders.
Results: Of 9088 recruited patients (mean age =61.30±12.25 y; 5557 men [61.1%]), 838 were rural residents. A positive family history of coronary artery disease (P=0.003), smoking (P=0.002), and hyperlipidemia (P=0.026), as well as a higher body mass index (P=0.013), was seen more frequently in the urban patients, while the rural patients had lower education levels (P<0.001) and higher unemployment rates (P=0.009). In-hospital mortality occurred in 135 patients (1.5%): 10 rural (1.2%) and 125 urban (1.5%) patients (P=0.465). The Firth regression model, used to adjust the effects of possible confounders, showed no significant difference concerning in-hospital mortality between the rural and urban patients (OR, 1.57; 95% CI, 0.376 to 7.450; P=0.585).
Conclusion: This study found no significant differences in receiving proper treatment and in-hospital mortality between rural and urban patients with ACS.

Published: June 2022

Background: Identifying the long-term predictors of recurrent cardiovascular events may help improve the quality of care and prevent subsequent events. We aimed to investigate the predictors of 1-year major cardiovascular events (MACE) in patients discharged after ST-elevation myocardial infarction (STEMI) in a tertiary hospital in Iran.
Methods: This registry-based cohort study included consecutive STEMI patients between 2016 and 2019 in Imam-Ali Hospital, Kermanshah, Iran. All patients discharged alive from STEMI hospitalization were followed up for 1 year for MACE, consisting of all-cause mortality, nonfatal MI, and nonfatal stroke. We estimated the hazard ratio (HR) and the 95% confidence interval (95% CI) using Cox proportional-hazard models to evaluate potential predictors, including demographic characteristics, medical history, cardiovascular risk factors, laboratory tests, reperfusion therapy, and medications.
Results: During 2187.2 person-years, 21 patients were lost to follow-up (success rate =99.1%). Of 2274 post-discharge STEMI patients (mean age =60.26 y; 21.9% female), 151 (6.6%) experienced MACE, including, all-cause mortality (n=115, 5.1%), nonfatal MI (n=20, 0.9%), and nonfatal stroke (n=16, 0.7%). Independent predictors of MACE were age (HR:1.02; 95% CI: 1.00–1.04), no education vs ≥12 years of formal schooling (HR: 2.07; 95% CI: 1.17–3.67), stroke history (HR: 2.37; 95% CI: 1.48–3.81), the glomerular filtration rate (HR: 0.98; 95% CI: 0.97–1.00), the body mass index (HR: 0.94; 95% CI:, 0.89–0.99), peak creatine kinase-MB (HR: 1.00; 95% CI: 1.00–1.002), thrombolysis vs primary percutaneous coronary intervention (HR: 1.85; 95% CI: 1.21–2.81), and left ventricular ejection fraction <35% vs ≥50% (HR: 2.82; 95% CI: 1.46–5.47).
Conclusion: Age, education, stroke history, the glomerular filtration rate, the body mass index, peak creatine kinase-MB, reperfusion therapy, and left ventricular function can be independently associated with 1-year MACE.

Published: June 2022

Kawasaki disease (KD) is a febrile vasculitis and is considered a leading cause of acquired coronary artery disease in children. A clinically critical complication is the coronary artery aneurysm, which may progress and lead to coronary stenosis or even obstruction. Herein, we describe a 14.5-year-old boy with a history of KD at 6 months old, who developed multiple aneurysms along all the coronary branches. During the follow-up at the age of 14 years, the left coronary artery aneurysms regressed, while the aneurysm of the right coronary artery persisted and was complicated by obstruction at its proximal part, according to computed tomography angiography. However, the patient at the last follow-up was asymptomatic and well.
The serious nature of KD coronary complications warrants follow-up visits. Since echocardiography alone may fail to reveal stenosis or obstruction, other adjunct follow-up imaging modalities such as conventional, computed tomography, and magnetic resonance angiography should be performed in patients with coronary aneurysms.

Authors: Görmez Ayça Berna
Published: June 2022

Kalp Gidince, Amerika Birleşik Devletleri’nde geçen distopik bir romandır ve bankacılıktan üretime her sektörün çöktüğü bir toplum anlatılır. Kitapta, işsizlik, evsizlik ve şiddet istisnadan ziyade normu oluşturmaktadır. Hikaye evlerini ve işlerini kaybeden ve arabalarında yaşayan genç bir çift üzerinden anlatılır. Bu çift, artık sadece hayatta kalmaya çalışmakta ve güvenlik uğruna özgürlüklerinden vazgeçmektedir.
Distopyalar yazıldığı dönemin korkularını ele alırlar. Romanda anlatılan toplum geç kapitalist bir toplumdur. Geç kapitalist toplumlar belirsizlik, güvensizlik ve kırılganlık üzerine kurulmuşlardır ve bunlardan kaynaklanan korku ve endişeyi sömürmektedir. Kalp Gidince romanı da bu sömürüyü yansıtmaktadır. Romanda kahramanlar güvenlik ve istikrar vaat eden bir projeye dahil olmakta, sonucunda özgürlüklerini kaybetmektedir. Çalışmanın ilk bölümünde distopya ve sosyal teori ilişkisi ele alınmıştır. İkinci bölümde romanın özeti ve bağlamı verilmiştir. Üçüncü bölümde geç kapitalist toplumların analizi akışkan modernlik tezi üzerinden yapılmıştır. Son bölümde özgürlük ve güvenlik arasındaki çelişkili ilişki ele alınmış ve bu çelişkili ilişki sonucunda ortaya çıkan tahakküm ilişkileri analiz edilmiştir. Çalışmanın temel tezi, korkuyu harekete geçiren ve sömüren toplum yapısının güvenlik ihtiyacını tetiklediği ve bu ihtiyacının özgürlük kaybına yol açacağıdır.

Systolic Myocardial Velocity by Tissue Doppler Imaging versus Left Ventricular Ejection Fraction by Simpson’s Method in Yemeni Patients with Heart Failure
Authors: Obeid Faida
Published: June 2022

Objective: To compare between systolic myocardial velocity (Sm) by tissue Doppler imaging (TDI) and left ventricular ejection fraction (LVEF) by Simpson’s method in Yemeni patients with heart failure (HF).

Method: This study included 85 HF patients whose LVEF was <50.0%. LVEF was measured by Simpson’s method and Sm was measured by TDI at septal, lateral, anterior and inferior sides of the mitral annulus.

Results: The mean age of the patients included in the study was 58.5 ± 11 years. The mean LVEF was 33.53 ± 9.94, while LV mean Sm (cm/s) was 2.67 ± 1.43. A significant correlation was detected between LVEF obtained by Simpson’s method and LV mean Sm obtained by TDI (r = 0.609, P < 0.001).

Conclusions: A significant correlation was found between LVEF and Sm among Yemeni patients with HF. Therefore, Sm obtained by TDI can replace LVEF in the assessment of LV systolic function in Yemeni HF patients. Large-scale, controlled studies are recommended to provide further evidence on the utility of Sm by TDI in assessing the LV systolic function in HF patients in different areas of the country.

One way that can be done to reduce air pollution and production costs in concrete is by utilizing waste that is no longer used, one of which is by using corncob ash. The addition of corn cob ash is expected to make a positive contribution to the concrete, by providing adhesion to the concrete mixture so that it can increase the compressive strength. This study aims to determine the effect of adding corncob ash to the concrete mixture on temperature variations that will be used in burning corncobs. The compressive strength test was made using the standard method of SK SNI T-15-2000-03. All samples were made using a cube mold with dimensions of 15cm x 30cm. This test uses 36 samples consisting of normal concrete and 3 variations of corncob ash content ranging from 5%; 10%; 15%.. Based on the analysis of the compressive strength tester at the age of 28 days, the results were 19.67 MPa; 19.74 MPa; 21.81 MPa; 18.98 MPa. With an increase in the maximum compressive strength of 23.714 MPa at an optimum level of 10%. where the added material content of 10% has the highest compressive strength value compared to other corncob ash additions.

Published: June 2022

Protests by the Fridays for Future movement occupied squares and streets of countries all over the world in 2019. Thanks to their popularity, they successfully brought the topic of climate change to the attention of the mass media, politics and the public. This case study is focused on the process of creating the movement’s narrative. It is based on a qualitative content analysis of inscriptions and pictures on banners that were part of the demonstrations in Brno, Bratislava and Vienna. At the centre of analysis are the past, the present and the future as important motifs of the narrative. The main question of the case study is how the demonstrators interpret, reinterpret and make constructions of these time perspectives from their specific social position, and how this interpretation is becoming a part of the narrative of the movement. The second focus of the paper is on the influence of the narrative on climate change in co-creating generation identity.

The study deals with the San Juan farmstead near the town of La Unión in southern Chile. It was owned by R. A. Philippi, who was among the first generation of German colonists to settle in the southern territories of Chile. The management of the farmstead’s affairs was entrusted to custodians, and Julius Böhlendorf, the husband of Philippi’s daughter Ella, held this position from the 1870s. The Böhlendorfs lived on the estate for almost thirty years and managed its everyday operations. This study focuses on the period between the 1860s and the 1880s and the text is based on a thorough study and interpretation of archive records, particularly the diaries and letters of members of the Philippi and Böhlendorf families (stored in the Dirección Museológica de la Universidad Austral de Chile archive in Valdivia). The main aim of the work is to present and give a sense of the functioning of the farmstead and to show its structure and the kinds of work done there.

Una enfermedad zoonótica es aquella que puede ser transmitida desde animales hacia el hombre, entre ellas, la de tipo parasitaria más relevante es la toxocariosis, por su prevalencia sobre todo en niños que tienen algún contacto accidental con el parásito en zonas públicas que fueron contaminadas previamente con las heces de los perros parasitados. El humano, por tratarse de un hospedero accidental, no genera estadio adulto del parásito, sin embargo, las larvas entran a circulación generando los síndromes de Larva migrans ocular y Larva migrans visceral. El presente trabajo busca determinar la contaminación por huevos de Toxocara canis en parques del distrito de Independencia- Lima, Perú. Se recopilaron muestras de los 71 parques del distrito en el periodo de mayo a julio del 2017. La evaluación se realizó mediante la técnica de recolección de muestras de la doble W con el objetivo de obtener 1 kg de tierra de cada parque, luego fueron procesadas a través del método de flotación de Willis para la recopilación de los huevos de Toxocara canis. Se obtuvo 1 parque positivo de los 71 parques no cercados evaluados, así mismo no se encontró asociación entre la presencia del parásito y el estado de conservación de los parques (P>0.05)

Authors: Al-Muylaba Mohammed , Abdel Dayem A. M.
Published: June 2022

An innovative design of a solar natural vacuum desalination (SNVD) system is proposed and investigated. To obtain a vacuum pressure in a desalination chamber its height is considered as 9.5 m. The waste heat in the system is efficiently utilized for both brine and distilled water. Seawater is preheated by the produced warm water, then, it is heated again by the outlet rejected hot brine before it is charged into the evaporation chamber. In addition, inlet pure water to a flat-plate collector is preheated by the condensation latent heat of the evaporated vapor from the evaporation chamber. Later, the outlet hot water from the collector is used as a heat source to the evaporation process. An optimum design of the system components was provided under the actual weather conditions for the shortest day of the year. It was found that the collector area is required to be 23 m2 to produce 66.6 liter of distilled water during. A mathematical modeling of the system was provided to establish a transient simulation and investigate the hourly performance of the system. Based on the annual performance of the system, the system can produce 76.5 liter of distilled water daily that is corresponding to 3.5 liter per one quadratic meter of collector. The annual average specific productivity of the system is obtained as 1.44 liter per kWh of solar radiation. Moreover, the maximum annual production is estimated as 92.88 liter of distilled water per day. Accordingly, the evaporation ratio (ER) is dependent on the solar irradiation and the annual average is found 0.0175 (or 1.75 %) where the gain output ratio (GOR) was estimated as 0.97 on yearly average basis.
