Objective: to determine antimicrobial resistance of Enterococcus faecium and Enterococcus faecalis isolated from blood culture of hematological patients during different study periods.Materials and methods. Antimicrobial susceptibility of Enterococcus spp., collected as part of the multicenter study was tested by the broth microdilution method (USA Clinical and Laboratory Standards Institute (CLSI), 2018), to daptomycin by Etest (bioMeriéux, France). High-level gentamicin resistance (HLGR) and high-level streptomycin resistance (HLSR) was performed by the agar dilution method (CLSI (Oxoid, UK), 2018).Results. The susceptibility of 366 E. faecium (157 in 2002-2009 and 209 in 2010-2017) and 86 E. faecalis (44 in 20022009 and 42 in 2010-2017) was studied. In the second study period (2010-2017) the rise of vancomycin-resistant E. faecium (VREF) increased from 8.3 % to 23.4 % (p = 0.0001), and two linezolid-resistant (LREF) were identified. All VREF and LREF remained susceptible to daptomycin and tigecycline. The rate of susceptible to tetracycline E. faecium remained the same (73.9 and 74.6 %), and an increase in susceptibility to chloramphenicol (74.5 and 82.3 %) was observed. Susceptibility of E. faecium to tetracycline was detected with almost the same rate and in a part of isolates, the increase of susceptibility to chloramphenicol was registered during the analyzed periods. The rise of E. faecium susceptible to HLGR and HLSR has increased significantly in 2010-2017 compared to 2002-2009. Erythromycin, levofloxacin, ampicillin and penicillin had the least activity against E. faecium (less than 5 %).All E. faecalis were susceptible to tigecycline, linezolid, and teicoplanin. Only one of E. faecalis had intermediate resistance to vancomycin. High susceptibility to ampicillin in E. faecalis remained unchanged (97.7 and 97.6 %, respectively). In the second period of the study the rise of susceptible E. faecalis decreased significantly to penicillin (from 97.7 % to 76.2 %), to levofloxacin (from 59.1 % to 31 %), to HLSR (from 52.3 % до 31 %), and to HLGR (from 47.7 % to 26.2 %), remained unchanged to chloramphenicol (52.3 % and 50 %) and was minimal to erythromycin and tetracycline.Conclusion. The study demonstrated higher rates of antibiotic resistance among E. faecium, which consisted of an increase in VREF and the appearance of linezolid-resistant strains. High susceptibility to ampicillin remained in E. faecalis, but there was an increase in resistance to penicillin and aminoglycosides.
A NEW-FANGLED CONTROLLING STRUCTURE FOR MITIGATING VOLTAGE SAG USING THE DVR
Authors: Et. al. B. Durai Babu, 
Published: April 2021

Voltage mitigation in electrical power circulation systems is unique of the crucial errands in recent days, which affects the overall presentation of the distribution system. The voltage sag must be detected and mitigated by implementing a Dynamic Voltage Restorer (DVR). The current works aimed to develop some controlling structures for reducing the voltage sag in the power system. Still, it remains with increased transients, incapability to compensate the mark voltage, and increased voltage limits. Thus, this paper intends to develop a new controlling algorithm, namely, Synchronous Reference Theory (SRF), for voltage sag mitigation. This Controller's primary considerations are to moderate the voltage sag, analyze the imbalance cutting-edge source voltage, and reduce the harmonic content. Here, the 3-phase load current obtained from the non-mark ar load is given as the input, which is transformed into dq0 reference. The DC quantities are extracted and presented as the input for the extraordinary pass purifyingmethod, eliminating the vocal contents. Then, the SRF controller produces the switching pulses for the Z-source inverter, which reduces the voltage sag. Finally, the presentation of the Controller is evaluated by analyzing the power ingesting and effectiveness.
DESIGN AND FABRICATION OF SOLAR TUNNEL DRYER FOR COPRA APPLICATION
Authors: Et. al. P.M. Venkatesh, 
Published: April 2021

A semi-cylindrical forced convection type solar tunnel dryer (STD) was designed and commissioned at M/s Miraj Products Pvt. Ltd., Nathdwara for drying processed tobacco. Essentially it is based on the mixed mode with direct and indirect type of heating mechanism i.e. the heated air from different solar flat plate collectors is passed through drying cabinet. At the same time, the drying cabinet absorbs solar energy directly through the transparent walls and roofs. It consists of 16×3.75 m2 area, tunnel equipped with 12 solar flat plate collectors of 2 m2 each propelled with 2 exhaust fans of 1 kW capacity placed on both ends of the tunnel. The dryer was tested at no-load and full-load conditions. During no-load, without flat plate collectors, temperatures inside the dryer were about18-20℃ higher than the ambient temperature during summer day-light, where as in no-load with flat plate collectors, it was about 30℃ higher than the ambient temperature. A batch of processed tobacco of 500 kg with an initial moisture content 138% d.b. were successfully dried in full load condition to have final moisture content of about 8.7% d.b. in 8 h. It has been observed that STD has many other advantages i.e. getting rid of toxicant gas to labours during opening drying due to lime presence in material, avoidance of product expose to fly contamination and dust concentrations etc.
EFFECT OF PERSONAL BRANDING EFFORTS ON JOB PROSPECTS OF A LINKEDIN USER
Authors: Et. al. Arghyadeep Basu, 
Published: April 2021

In this article, the authors examined the relation between Personal Branding efforts in LinkedIn and their job prospects. While there are other social media sites which can be taken into consideration for the study, LinkedIn is deemed to be a purely professional social networking site with content relevant to jobs, industry, economy etc. The authors found that sizable LinkedIn users do not post, share or visit content with the intent of “Building Personal Brand”, however wishes to attract the attention of potential recruiters on the platform. While the term “Personal Branding has been discussed in numerous papers, journals and articles, broader clarity is guaranteed on the same. Additionally, it was duly noted that a person looking for a job doesn’t trust LinkedIn entirely and thus signs up on various other established job portals or seek suitable referrals at the same time.

“Your brand has moved online. That means you need to translate who you are in the real world into a congruent bits-and-bytes version of you. First impressions are important to your career success, so whether they take place with a handshake or on a handheld device, you need to make sure yours is authentic, compelling, and relevant.”, said Mitch Joel in his book ‘Ctrl, Alt, Delete’.

“It is much more than a style of dress, a particular degree or credential, or the associations to which you belong. Mainly it is the unique “stamp” you put on everything you say or do. Because no one will do things and present themselves in exactly the same way that you do, your uniqueness is what people notice”- Annabelle Reitman and Caitlin Williams on Personal Branding in their periodical journal ‘Distinguish yourself and excel in the profession’.

Author Neal Schaffer in his journal “LinkedIn or Left Out” shares his view on LinkedIn by stating- “It is much more than a style of dress, a particular degree or credential, or the associations to which you belong. Mainly it is the unique “stamp” you put on everything you say or do. Because no one will do things and present themselves in exactly the same way that you do, your uniqueness is what people notice.”

Further legal trainer Avery Black feels “The most effective way to start your job search is by developing relationships with people. The Internet, through professional websites like LinkedIn and social media sites like Face-book and Twitter, allows people to start a dialogue with each other.”

The above quotes individually bring out the core pointers of this literature- “LinkedIn” and “Personal Branding” and “Job Search”. “Branding” which audiences still relate to tangible products have slowly seeped into individuals. Individuals are making informed decisions and suitable actions in order to attract the attention of a specific set of people which in this case are job recruiters.

Unparalleled development in information communication technology (ICT) has led people to live in the virtual world. Smartphone has made peoples’ life more comfortable as they do purchase goods and services while they are on the move. People likely to buy the products online from candy to newspaper. Purchasing newspaper online is currently in a blunder stage, however, steady growth has been reported in the recent past on the purchase of e-newspaper around the world. Therefore, this study aimed to investigate the factors that influence the purchase intention of consumers towards digital/e-newspaper in Sri Lanka. Data were collected for this purpose via a structural questionnaire from those who involve online purchasing either in their home or office in Ampara districts of Sri Lanka. 305 sample response were collected and analysed further with Structural Equation Modelling (SEM) using AMOS. The results revealed that Website Quality (WEBQUAL) and Online Customer Reviews (OCR) post a significant positive influence on the Online Consumer Purchase Intention (OCPI) of the digital newspaper. Meanwhile, Paid Content (PC) was negatively associated with the purchase intention of the digital newspaper which indicates that consumer was not ready to pay the content if it is charged. On the other hand, Trust was not a significant factor as long as e-newspaper purchase is concerned which is a noteworthy finding of this study unlike in the other context such as B2B market or B2C market. The findings of this provide some useful contribution to the literature of consumer behaviour and practitioners like newspaper companies to make a strategic decision on the future business model for digital/e-newspaper in Sri Lanka.
DESIGN OF SQUARE MICROSTRIP PATCH MULTI BAND ANTENNA FOR WIRELESS COMMUNICATION USING EBG STRUCTURE
Authors: Et. al. Suresh Akkole, 
Published: April 2021

Application of electromagnetic band-gap (EBG) structure and its use in the design of antenna and microwave integrated circuits is becoming more attractive. The recent electromagnetic band-gap structure method is capturing more importance in antenna design due to its uniqueness properties to suppress the propagation of surface waves in microstrip patch antenna. In this paper a square microstrip antenna is designed and its performance parameters are compared with geometry designed on EBG structure. The square antenna of 29 mm x29 mm size is designed at 2.455 GHz and analysis is done using IE3D simulation software. The proposed work mainly focuses on modification of antenna using electronic band gap structure (EBG). The antenna parameters such as Return loss, VSWR, Gain and Bandwidth, with and without EBG are obtained using IE3D simulation tool. The Electromagnetic band-gap structures have been used to improve the performance of the gain of the antennas and radiation patterns. One of the main advantages of electromagnetic band-gap structure is its ability to suppress the surface wave current present on the microstrip antenna. Combining the square patch with EBG structure, the bandwidth of the antenna has been increased by 34.66%, and attained gain of 44.44% at resonant frequency around 2.4 GHz as compared to the antenna without EBG..
ANALYSIS OF DRIVER BEHAVIOR IN VEHICLE FOLLOWING AND LANE CHANGING PARAMETERS ON URBAN MID BLOCK SECTIONS
Authors: Et. al. Sowjanya, 
Published: April 2021

In mixed traffic situations, there is weak or no lane behavior of the driver much more complicated where vehicle and driver behavior show a huge difference between them. Road traffic driving behavior on urban midblock sections is one of the most complex phenomena to be examined particularly in heterogeneous traffic conditions. This is often attributed to the capacity of the road section and the traffic flow features at the macroscopic and microscopic level of a road section. Very few researchers have attempted to investigate these features in heterogeneous environments because of the lack of adequate information gathering methods and the amount of complexity involved. In this background, an access controlled mid block road section was selected for video data collection. The main objectives of this study include developing vehicular trajectory data and analyzing the lane changing and vehicle following behavior of driver on the mid block section considering the relative velocities and relative spacing between various types of vehicles under heterogeneous traffic conditions. The videos were collected from urban roadway in the Kurnool district of Andhra Pradesh. The length of the stretch is 120m and the width is 7.0 m. The data was extracted to know the variations in terms of longitudinal and lateral speeds, velocities, vehicle following and lane changing behavior of the drivers. The data extracted was smoothened by moving average method to minimize the human errors. Lateral amplitude of the vehicles of various types was analyzed. The study revealed that vehicles in the mixed stream, in general and in particular, Bikes and Autos particularly move substantially in the lateral direction.

Published: April 2021

ABSTRACTThis study presents the coupling of the spectral decomposition results for anelastic attenuation, stress drop, and site effects with the Graves-Pitarka (GP) hybrid ground-motion simulation methodology, as implemented on the Southern California Earthquake Center (SCEC) broadband platform (BBP). It is targeted to applications in the Upper Rhine graben (URG), which is among the seismically active areas in western Europe, yet a moderate seismicity area. Our development consists of three main steps: (1) calibration of regional high-frequency (HF) attenuation properties; (2) modification of the hybrid approach to add compressional waves in the HF computation and examine various strategies to evaluate site amplification factors in the Fourier domain (e.g., VS30-based or site-specific factors); (3) testing of the simulations using earthquake records from the URG (3.7&lt;Mw&lt;5). The validation process of the simulated time histories is performed first on rock sites, and, then subsequently at all stations, whatever their site conditions. The performance of the simulations for rock sites is assessed through the standard validation technique in the BBP (comparison of the waveforms, intensity measures, and estimation of the response spectra model bias). We additionally compare the Fourier amplitude spectrum of the simulations and observations, and compute their corresponding bias. The results show that the simulated ground motions match the general characteristics of the recorded motions, and that the model bias generally fluctuates around zero across the broadband frequency range. Hence, the hybrid ground-motion methodology implemented in the SCEC BBP can be successfully applied outside high-seismicity areas and outside those areas for which it had been generally calibrated. Our results also show that HF modification and calibration were necessary to improve the fits with the observation, and demonstrate the potential benefits of using site-specific amplification factors compared to VS30-based amplification factors.

Aim To present clinical characteristics of patients after hospitalization for acute decompensated heart failure (ADHF) and to analyze hemodynamic indexes and compliance with the treatment at two years depending on the conditions of outpatient follow-up.Material and methods The study included 942 patients with chronic heart failure (CHF) older than 18 years who had been hospitalized for ADHF. Based on patients’ decisions, two groups were isolated: patients who continued the outpatient follow-up at the Center of CHF (CCHF) (group 1, n=510) and patients who continued the follow-up in outpatient multidisciplinary clinics (OMC) at their place of residence (group 2, n=432). The clinical portrait of patients was evaluated after ADHF, and hemodynamic parameters were evaluated on discharge from the hospital. Also, the patient compliance with the treatment was analyzed during two years of follow-up. Statistical analysis was performed with Statistica 7.0 for Windows.Results The leading causes for CHF included arterial hypertension, ischemic heart disease, atrial fibrillation, and type 2 diabetes mellitus. With the mean duration of hospitalization of 11 inpatient days, 88.1 % and 88.4 % of patients of groups 1 and 2 were discharged with complaints of shortness of breath; 62 % and 70.4 % complained of palpitations; and 73.6 % and 71.8 % complained of general weakness. On discharge from the hospital, the following obvious signs of congestion remained: peripheral edema in 54.3 % and 57.9 %; pulmonary rales in 28.8 % and 32.4 %; orthopnea in 21.4 % and 26.2 %; and cough in 16,5 % and 15.5 % of patients of groups 1 and 2, respectively. For the time of hospitalization, CHF patients did not achieve their targets of systolic BP (SBP), diastolic BP (DBP) and heart rate (HR). Patients of group 1 achieved the recommended values of SBP, DBP and HR already at one year of the follow-up at CCHF. Patients of group 2 had no significant changes in hemodynamic indexes. At one and two years of the follow-up, group 2 showed a considerable impairment of the compliance with the basis therapy for CHF compared to group 1.Conclusions During the short period of hospitalization (11 inpatient days), the patients retained pronounced symptoms of HF and clinical signs of congestion and did not achieve their hemodynamic targets. The patients who were followed up for a long time at CCHF were more compliant with the basis therapy, which resulted in improvement of hemodynamic indexes, compared to the patients who were managed in OMS at the place of residence.

Aim To develop a new, modified protocol for transesophageal atrial electric stimulation (TEAES), which would significantly enhance the diagnostic value of stress echocardiography and reduce the duration of the test in patients with ischemic heart disease (IHD).Material and methods This study included 101 patients (80 men and 21 women aged 55±9 years) with suspected or documented diagnosis of IHD who were divided into two homogenous groups. Group 1 (51 patients) underwent stress echocardiography (stress-EchoCG) according to a standard protocol (SP) for TEAES and group 2 (50 patients), underwent stress-EchoCG according to a modified protocol (MP). In addition to stress-EchoCG with TEAES, selective coronary angiography was performed for all patients. The development of the new method for evaluating occult coronary insufficiency was based on comparison of SP and MP for TEAES with stress-EchoCG with data of coronary angiography.Results In both groups, significant differences in values of systolic and diastolic blood pressure were absent. However, the values of achieved heart rate were significantly different: 141±11 (TEAES SP) and 155±10 (TEAES MP) bpm (p=0.01). There was also a difference in the duration of the TEAES protocols: 15±3 and 5±2 min, respectively (p=0.006). The use of the modified TEAES protocol for detecting transient disorders of left ventricular myocardial local contractility increased the sensitivity, specificity and accuracy of the test from 76 %, 87 %, and 80 % to 83 %, 92 %, and 86 %, respectively. The most significant differences were found in the area supplied by the circumflex artery: the SP and MP sensitivities were 63 % and 75 %, respectively (p<0.05) and the SP and MP accuracies were 81 % and 90 %, respectively (p<0.05).Conclusion Evaluation of occult coronary insufficiency by stress-EchoCG with the TEAES MP as compared to the TEAES SP provides a gentler procedure regimen for the patient due to a shorter duration of the test and at the same time improves the diagnostic significance of this method in IHD patients.

Aim To compare results of computed tomography coronary angiography (CTCA) with a table of pretest probability of chronic coronary syndrome (CCS) taking into account the following key variants: abnormality, microvascular damage, nonobstructive or obstructive atherosclerotic damage.Material and methods 50 patients (39 men, 20 women) aged 30 to 67 years were evaluated with a computed tomography scanner PHILIPS Brilliance iCT SP 128. A high pretest probability of ischemic heart disease was found in 44 % of cases and medium in 40%.Results According to CCS data, coronary artery (CA) pathology was not found in 28 % of patients. CA hypoplasia was observed in 4 % of patients. 22 % of patients had muscular bridges narrowing the CA lumen during systole by 40-50%. In 26 % of cases, CA had minimal and early stenoses. Moderate and pronounced stenoses were observed in 20% of cases. In one case, there was a total occlusion of the circumflex branch. Calcinates were found in 9.1 % of patients with muscular bridges, in 61.5 % of patients with minimal and early stenoses, and in 80% of patients with moderate and pronounced stenoses. In the group with “clean” CA and congenital defects, calcinates were absent. The mean value of pretest probability was the highest in the patient group with moderate and pronounced stenoses, 22.5±13.13. It was significantly higher than in the group with muscular bridges (р=0.045) and congenital pathology of CA (р=0.01). At the same time, this value did not significantly differ from the group with “clean” CA and the group with minimal and early stenoses. Based on the study results, 2 bypass surgeries and 5 CA stentings were performed.Conclusion Thus, the table of pretest probability of ischemic heart disease does not provide a differential diagnosis and evaluation of the nature of CA damage as compared to results of CTCA.
