Authors: Komarov V. V. , Bushanskiy S. K. 
Published: March 2020

Introduction. Simple-shaped cavity resonators: rectangular, cylindrical and coaxial, are widely applied in modern microwave engineering in design of different functional devices of middle and high power levels. Parameters of resonators can be obtained analytically by using expressions from literature. Concentric resonators, performed on the basis of classical simple-shaped cavities with a central metallic core represent a new class of electrodynamic systems of microwave range, the properties of which remain poorly studied. One of these structures, named a rectangular concentric resonator (RCR) is proposed in the paper as a basic unit of K-band bandpass filters (18...26 GHz).Aim. To study potential possibilities of RCR for creation electromagnetic signals filtration devices of micro wave range.Materials and methods. The finite element method implemented in the package COMSOL was used to investigate electrodynamic characteristics of RCR and scattering matrix parameters of the microwave filters on RCR basis.Results. Simple polynomial expressions for computation of normalized resonant wavelengths of RCR were obtained at the first stage of modeling. Next, two models of passband microwave filters by RCR with different sizes were built and their EM characteristics were studied. Cavities sizes were determined numerically and practical recommendations on the realization of a new type bandpass microwave filters were formulated.Conclusion. New results of the finite-element analysis of spectral characteristics of two models of bandpass Krange filters on rectangular concentric resonators were represented. The advantages of the filters were indicated. Simple analytical expressions for calculation of the resonance wavelengths of the considered concentric resonators were obtained.

Introduction. The present stage of development of hydroacoustic equipment is characterized by a constant improvement of an element base and by an increase in computing power. However, in solving of applied problems one is increasingly faced with a restriction on the realized bandwidth of electroacoustic transducers and antennas. The most of well-known methods of bandwidth expansion do not provide a linear character of the phase-frequency characteristic (PFC) of radiation in the working frequency band, which is of primary importance for the effective formation of relatively short, frequency-tunable, and complex acoustic signals. From this position, the use of a transducer of waveguide type (TWT) is preferential. Its construction and electrical excitation method provides a close to linear phase response of radiation.Aim. The development of a generalized computational model. It has to include particular cases of TWT radiation into cylindrical waveguides coaxial with it and into half-spaces, and also to take into account the influence of waves reflected from the boundaries of the TWT on its field characteristics.Materials and methods. The TWT was presented by a coaxial set of identical water filled piezocylinders with amplitude-phase excitation, provided a mode of broadband radiation in the form of traveling waves. The usage of the method of partial regions allowed one to obtain a solution of the problem of TWT radiation through water filled apertures into the conical adjacent half-spaces, variable in angle.Results. Frequency characteristics of TWT sound pressure results calculated in accordance with the solution of the synthesis problem in the frontal and rear directions for different angles of cone opening were presented and analyzed. Using the proposed computational model of TWT, the possibility of obtaining a bandwidth of the order of 3 octaves was demonstrated. An influence of the thickness of the passive flanges, which are used to link the TWT in the antennas was estimated. The possibility of radiation in the working frequency band of TWT of ultrashort ultra-short single-period pulses for different angles of cone opening was considered. A comparative assessment of the result of calculation with other particular solutions (the radiation by TWT in coaxial water-filled waveguides and also – in half-spaces) was presentedConclusion. An expedient to use a generalized computational model for a more accurate description of the acoustic fields of real antenna models made up of TWT was concluded.

Introduction. Cardiopulmonary stress test provides significant diagnostic and prognostic information of the condition of patients with cardiovascular and pulmonary diseases. There is a serious problem, that final phase of stress testing is a physically difficult exercise for a person. There is a significant risk of occurrence and development of pathological conditions of the patient's cardiovascular system. One of the solutions is the development of methods for assessing the biological parameters of the patients at the end of a load protocol based on data from the initial stages of the test.Aim. Development of a method for finding an estimate of the maximum heart rate (HR) and of the peak oxygen consumption (OC) for the patients with chronic heart failure at the end of a cardiorespiratory exercise stress test, based on the results of the study obtained at the first initial stages of the test.Materials and methods. For the study, 149 anonymized records of rhythmograms and data of changes in the oxygen consumption of the patients with chronic heart failure were used. The patients underwent a cardiopulmonary stress test by a bicycle ergometer using step-by-step load protocol (the load power increase at each stage was 10 W, the duration of the load stage was 1 min)Results. Based on the analysis of the data obtained, a method for assessing the peak values of HR and of PC of the patients with chronic heart failure was developed.Conclusion. The relative error of the proposed estimate of the HR peak in most cases was no more than 10 %, which allows it to be used for practical purposes. It was established that when performing 70 % of the stress protocol, the error of the proposed estimate of the OC peak in most cases did not exceed 20 %. More research is needed to improve the accuracy of the assessment for using in medical applications aimed to the modernization of methods and equipment for stress testing of the patients.

Mewujudkan Good Governance dalam Implementasi Program Pemberdayaan Badan Usaha Milik Desa di Jawa Timur
Authors: Wahyudi Kalvin Edo 
Published: March 2020

Abstrak
Pemerintah Provinsi Jawa Timur telah merilis program pemberdayaan Badan Usaha Milik Desa (BUMDesa) yang bertujuan untuk mendorong pendirian dan pengembangan BUMDesa agar dapat menjadi instrumen dalam mewujudkan kemandirian desa dan kesejahteraan masyarakat. Program tersebut didesain atas dasar nilai dan prinsip-prinsip good governance. Penelitian ini merupakan salah satu bentuk analisis kebijakan publik yang bertujuan untuk menganalisis penerapan nilai dan prinsip-prinsip good governance sebagaimana dimaksud. Penelitian dilaksanakan dengan pendekatan kualitatif. Data dikumpulkan dengan teknik wawancara, observasi serta studi dokumen. Adapun teknik analisis data yang digunakan adalah model interaktif dengan teknik uji keabsahan data melalui triangulasi. Hasil penelitian menunjukkan bahwa penerapan nilai dan prinsip-prinsip good governance dalam pemberdayaan BUMDesa di Jawa Timur belum optimal, baik pada level analisis desa maupun supra desa. Pada level desa, dominasi pemerintah desa, rendahnya partisipasi masyarakat dan adanya sikap diskriminatif pada elemen masyarakat tertentu akibat perbedaan sikap politik menjadi kendala dalam pemberdayaan BUMDesa. Sedangkan pada level supra desa, aktor-aktor governance memang telah memberikan kontribusi yang nyata dan positif dalam pemberdayaan BUMDesa. Namun, kontribusi tersebut cenderung parsial dan bukanlah hasil dari interaksi dialogis dari aktor governance. Hal ini disebabkan belum ada komunikasi intensif dan peta peran yang jelas antar ketiga aktor governance dalam implementasi pemberdayaan BUMDesa di Jawa Timur.

Antibiotic resistance pattern of bacteria isolated from outdoor patients in Dhaka city: a single center study
Authors: Khatun Most Salma , Nahar Saimun , Kabir Md Shahidul 
Published: March 2020

Bacterial infections are often found to cause morbidity and mortality around the globe. Indiscriminate use of antibiotic for treatment of such infections is reported to cause selective pressure and increase in drug resistance. Emergence of antibiotic resistance is a growing concern for people of all age having bacterial infections. It is important to determine the trend of antibiotic resistance patterns of pathogenic bacteria isolated from clinical samples for appropriate treatment of patients. A retrospective study was conducted on patient samples collected from 1 July 2018 to 15 March 2019. A total of 500 urine, 136 blood, 120 stool, 172 swab, 90 Sputum and 60 pus samples were randomly collected from both male and female patients of different age groups who reported to a diagnostic centre in Dhaka city. Pathogenic bacteria were isolated and identified from the collected samples following standard methods. Antibiotic sensitivity patterns of isolated bacteria were also determined by disc diffusion test. Proportion of UTI in female patients (71.67%) was found to be higher than the male (28.33%) patients and mostly caused by Escherichia coli (73.33%). Among Gram negative bacteria, E. coli (51%) was found to be predominant followed by Pseudomonas spp. (11.47%), Klebsiella (9.84%) and Salmonella Typhi (9.84%). Among Gram positive organism Staphylococcus aureus (9.0%), beta haemolytic streptococci (5.74%) and enterococci (3.28%) were found to be present. Among the tested antibiotics imipenem was found to be the most effective (93.02%) followed by gentamycin (76.03%) against all isolated bacteria. Amoxycillin was found to be least effective (21.29%) against all isolated bacteria. Increase in antibiotic resistance was possibly due to indiscriminate use of antibiotic for treatment of various infections. Prudent use of antimicrobial drugs will help reduce spread of resistant bacteria and complication of treatment of infected patients.

Published: March 2020

A country like Bangladesh where textile industries are the main source of developing economy, pollution problem from such industries creates a huge risk for the environment. Textile industries discharge a huge amount of effluent containing various harmful chemicals including synthetic dyes that are very stable and threat to the living organisms. This study deals with the potential decolorization and biodegradation of Bemacron Yellow HP-2R (BY), Bemacron Red RS (BR) and Bemacron blue RS 01 (BB) dyes using bacteria isolated from textile effluent. The effluent and soil samples were collected from different locations of discharge point. Only two isolates were screened out after primary screening using dye supplemented nutrient agar media. Following colony morphology, physiology and biochemical analysis, they were presumptively identified as Bacillus sp. and Staphylococcus aureus. They were subjected to decolorization of 0.002 g/l BY, BR and BB dyes. Bacillus sp. showed superior decolorization potential of BR (71%) and BB (83%) dyes after 5 days of incubation. Whereas, Staphylococcus aureus showed 79% decolorization of BY dye after 5 days incubation. Decolorization efficacy can be further improved by optimizing environmental conditions and process parameters.
