Authors: V. Nagaraj , Vasudeva Reddy T. , S. Hariharan , P. Ramya
Published: March 2022

This chapter proposes a unique twofold-enabled name-getting wire plan for exceptionally high dull radio recurrent seeing insistence (UHF RFID) with polarization or rehash band mix using mode appraisal for unquestionably high irregular radio recurrent seeing attestation (UHF RFID) with polarization or rehash band blend using mode evaluation for incredibly high discontinuous radio recurrent seeing assertion (UHF RFID). The proposed mark game-plan joins two drifter line ties or dipole-like turn of events (appears to be like a planar pyramid), shorting nails, and a ground plane. Laying an upper fix over FR 4 substrate and shorting it from all sides to the ground plane with shorting nails is a pivotal strategy. In the wake of completing the brand name mode evaluation in the fundamental course of action, inclining openings are made to move the boisterous lead of related brand name modes to the lower go over band. In any case, the characteristics strategies for inclining holes-based plan in the US RFID band really show inductive lead (902 - 928 MHz).

Published: March 2022

One of the standards in wireless communication is Narrowband IoT. It deals with low power, small gain, and more life expectancy. The connectivity problem is reduced in narrowband design. This is achieved with microstrip antenna. Single patch is designed with the selected dielectric substrate. Several parameters are considered for the antenna design. The high value of dielectric constant reduces bandwidth in smaller patch for internet of things (IoT) design applications. These applications require gadgets for operating in licensed band of frequencies with less data rate and required antenna efficiency. When compared to dielectric, FR4 is a commonly available substrate and useful in smaller patches. In this chapter, two antennas are presented. The antennas were simulated in IE3D software and analyzed for Narrowband IoT (NB-IoT) with 100 MHz.

Published: March 2022

A reflect cluster receiving wire (RAA) with a wideband high-power double branch helical reflect cluster is demonstrated. Two metal helical branches make up the reflecting component, and the movable pivot points allow for full 360o stage rotation. A 9 X 9 rectangular cross section X-band RAA model is imitated and estimated. The best get of 23.7 dB is achieved with the bar concentrated at (=20,=0) course at focus repeat of 9.3 GHz, and the 1-dB get a move on is more than 24.2%, according to full-wave reenactments. In the entire band, the intentional reflection coefficient is not exactly - 16.3 dB. The endeavored significant rate is under 2.3 dB from 8.4 GHz to 10.8 GHz. The attempted get at center rehash is 23.4 dB, and the differentiating opening helpfulness is 50.6%. The RAA's bar inspecting execution is endeavored inside 30o exactness in two balanced planes with a check trouble of under 1.5 dB and focus point degrees of under 1.4 dB. Under vacuum, the mirrored results provide the appearance that the RAA's force taking care of limit is approximately 358 MW.

Authors: N. Vikram , V. Sudha , P. Divyabharathi , K. R. Deepa
Published: March 2022

Reconfigurable antennas (RA) are capable of dynamically altering their frequency, polarization, and radiation properties in a controlled and reversible manner. They modify their geometry and behaviour to maximize the antenna performance in response to changes in their surrounding conditions. To implement a dynamical response, they employ different mechanisms such as PIN diodes, varactors, radio-frequency microelectromechanical systems (RF-MEMS), FETs, parasitic pixel layers, photoconductive elements, mechanical actuators, metamaterials, ferrites, and liquid crystals. These mechanisms enable intentional distribution of current on the antenna surface producing reversible modification of their properties. This chapter presents the design process and applications of RA. The latest advances on reconfigurable metamaterial engineering, and the current trends and future directions relating to RA are reviewed. Finally, the applications of RA in cognitive radio, multi-input multi-output (MIMO) systems, satellite communications, and biomedical devices are highlighted.

Published: March 2022

This responsibility provides a straightforward, financially sound foundation for complicated analyses of the field transmitted by a receiving wire. The proposed setup is based on a number of receiving wire tests identified with a number of stage contrast locaters and, in general, a control locater. Stage capacity appraisals are made to recuperate the hour of the radio wire under test. The major advantage of the proposed structure is that it doesn't need standard evaluation, making it reasonable for getting wire investigations in situ. Requirements like the measure of getting wires in the group (and thusly the quantity of stage contrast locaters) and organizing shortcomings are examined. The suggested design has been tested using off-the-shelf equipment for radio wire evaluation and diagnostics. The problems with the system's execution, as well as offered fixes for lowering its precision, have been incorporated. Diagnostics and radiation plan assessments, as well as those determined from another phaseless strate, emerge in the end.

Published: March 2022

The impact of admixture of both Ordinary Portland Cement (OPC) and steel slag was examined on the geotechnical properties of the lateritic soil, by conducting basic geotechnical tests: Particle size analysis, Consistency limits, Compaction, California Bearing Ratio (CBR) and Unconfined Compressive Strength (UCS) on both the natural and stabilized soil samples and results were subjected to statistical analysis using 2-way ANOVA (Analysis of Variance) at 5% level of significance. The natural soil was classified as s A-7-6 and MH under standard soil classification systems. Addition of steel slag lowered the liquid limit (LL) and plasticity index (PI), while cement increased the LL and decreased PI of the lateritic soil, respectively. With increasing content of slag and cement, maximum dry density increased with the corresponding decrease in optimum moisture content. CBR and UCS of the stabilized soil increased substantially with increasing contents of slag and cement. Both steel slag and cement have statistically significant effects on the geotechnical properties of the lateritic soil. Hence, this soil can be stabilized with addition of 12% steel slag and 6% cement contents for its application as an improved subgrade material for light trafficked pavement. Keywords: Lateritic soil, steel slag, cement, stabilization, Index properties, strength indices.

Authors: Al Omairi Saif , Okedu Kenneth E. , Al Balushi Marya
Published: March 2022

Electricity supply in Oman is very stable, however, power generation from gas turbines and fossil fuels, which are not environmentally friendly, contribute over ninety percent to the present power grid. Due to rapid development, the current power state of Oman is been over stretched. This is as a result of increased power demand, considering the size of the electricity network and the control strategies employed at different levels of the power system. Therefore, in order to keep pace with the recent development, it is paramount to integrate the current power grid of the country with smart grid technologies. Some of the benefits of employing smart grid technologies are; providing more reliable power, utilizing more efficient renewable power, employing a mix of energy sources, use of smart devices, mitigating carbon footprint, enabling the roadmap for electric vehicles, availing smart job opportunities, saving of energy via reduced consumption programs, improved customer services, accurate billings, detection of frauds and technical losses, increased competition, and levelling of the demand curve or peak reduction. This paper presents the dynamics of making the power grid of Oman smarter, based on the current power situation in the country. The paper addresses the penetration of smart grid technologies with the national power grid and also present an extensive review of power situation of Oman power system. Efforts were made to discuss the possible locations of wind and solar energy potentials, in the country, since they are the two commonly used and readily available renewable energy sources. There is no doubt that smart grid technologies like information and communication technology, data management, energy sales and smart metering strategies, would play a huge role in making the power grid smarter. In addition, some dynamic behavior of the power grid was analyzed considering the penetration of solar and wind energy, in the current power grid of Oman.

Published: March 2022

Differentiation between exudative and transudative pleural effusion is sometime problematic. This study aimed to evaluate the diagnostic value of C-reactive protein (CRP) in differentiation of exudative and transudative pleural effusion. This is an analytical epidemiologic cross-sectional study that evaluates the role of CRP in differentiating transudative and exudative pleural effusion. Patients were divided into two groups of exudates and transudates, based on Light’s criteria. The pleural effusion CRP levels were compared between the two groups. SPSS software version 16 was used for statistical analysis. The significance level was considered p<0.05. A total of 169 patients with pleural effusion enrolled in the study. Based on Light's criteria, 108 patients (63.9%) had exudative pleural effusion and 61 (36.1%) had transudative pleural effusion. The level of CRP in the pleural fluid of patients in the exudative and transudative groups was 13.3±37.1 and 3.5±4.3mg/dl, respectively (p=0.008). The 3.31 mg/dl cut-off point of CRP level of pleural effusion had the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 96.3%, 72.1%, 86% and 91.7% respectively.  The results obtained in our study shows that the level of CRP in the effusion fluid can be helpful in differentiating exudative from transudative pleural effusions.
Teaching Ethics to Medical Faculties
Authors: Srivastava Manushi , Shrivastava Sandeep , Srivastava Pradyumn , Srivastava Ratan K. , Jaiswal Shweta
Published: March 2022

Introduction:

Ethics is defined as a system of moral principles or standards governing conduct; a system of principles by which human actions and proposals may be judged good or bad, right, or wrong. However, ethics for medical teachers with respect to their students has been largely unnoted. Therefore, it seems necessary to know the status of teaching ethics practiced by medical educators which are the major assets in good quality medical education.

Objectives:

The objectives were to study the changes in the understanding and practices of teaching ethics and principles of medical professionals.

Methodology:

A prospective interventional study had conducted with 30 medical faculties.

Results:

Only one-third of the medical educators (33.33%) had reported that they have ever read any literature in “Teaching Ethics,” but after e-intervention, this purport increased to 90.48% as indicated by the posttest results.

Conclusion:

It could be concluded that faculties were quite aware of the basic philosophy of teaching ethics, but they also agreed with the fact that still, medical teaching is not up to the mark as per the norms of teaching ethics, although most of them were not in agreement of those unethical teaching practices.

Published: March 2022

Introduction:

The main purpose of hospitals is to provide quality care to their clientele. Many studies have been conducted to assess patient satisfaction and suggest measures to improve patient satisfaction in government and private hospitals. This study was conducted in a different setting with the aim to assess patient satisfaction in a group of hospitals exclusively for their entitled clientele.

Materials and Methods:

The study was a questionnaire-based observational study conducted in nine hospitals belonging to one central administration. The questions pertained to five domains. The data were collected on a numerical scale and the weighted average was calculated for each question.

Results:

A total of 2850 patients were administered with questionnaire. About 95% of patients were satisfied with services provided by the hospitals. The strengths of the hospitals were the general cleanliness and the way the medical and paramedical staff treat their patients. The weaknesses were the waiting period at reception and to see the doctor as well as the quality of food provided to the inpatients.

Conclusion:

This study has brought out that a large percentage of patients were satisfied with the services provided by the hospitals. The analysis has facilitated the administrator to know the strengths of the hospitals as well as to identify the weaknesses. It is essential that the administration of the hospitals addresses the weaknesses to further improve the patient satisfaction. In conclusion, it is recommended that patient satisfaction surveys should be part of the Standard Operating Procedure of all health-care facilities and the same should be an ongoing process rather than a one-time measure.

Authors: Jain Rahul , Singh Vani , Naik A. K. , Singh Santosh Kumar , Chakrabarty Barun Kumar , Ranjan Priya , Kumar Premshankar
Published: March 2022

Context:

Ulcerative colitis (UC) initially thought to be a disease of developed world is equally common in India. Surprisingly, there are very scant data from India. The study was undertaken to find the frequency of relapse and to determine factors predictor of relapse in Indian population.

Subjects and Methods:

This study was conducted at a tertiary care center of New Delhi for a period of 1 year. Patients were included if they had a diagnosis of UC based on accepted historical, endoscopic, histological, and/or radiologic criteria. Detailed past/present history, baseline clinical examination, dietary details, and psychological analysis using shortened Depression Anxiety Stress Scale score, biochemical tests, inflammatory markers, endoscopic, and histopathological analysis were done at baseline and regular intervals. The outcome was clinical relapse or continued remission.

Results:

Out of 86 patients screened, 50 patients were included in the study according to inclusion criteria and were followed up. The frequency of relapse was 32%. Univariate analysis showed higher relapse frequency, frequency of steroid received in past, patients on immunomodulator therapy, presence of acute or chronic inflammatory cells on histology, and disease activity at baseline as predictors of relapse. There was no significant difference between anxiety, stress, and depression relapsers and those who maintained remission. On multivariate analysis, disease activity at baseline was the only independent predictor of relapse.

Conclusions:

Stringent control of disease activity with mucosal healing should be the aim, as mucosal healing is the only predictor for prolonged remission.

Authors: S. Dhakad R. K. , Mishra Abhilekh , Naugraiya Tarun , Dhakad Vivek Singh
Published: March 2022

Introduction:

Femoral neck fractures are one among the leading causes of death in elderly patients. Magnitude of fracture displacement, patient's age, comorbid disorders, and prefracture activity level are some of the critical factors in determining the clinical practice for treating femoral neck fracture. In this study, we have studied the functional outcome and survivorship in fracture neck of femur in the elderly population operated with both internal fixation (IF) and cemented hemiarthroplasty (HA).

Material and Method:

All 100 patients were reviewed clinically and radiologically at 15 days, 1 month, and then subsequent 1 year. Out of 100 patients, 54 have been operated with HA and 46 have been operated with screw fixation.

Results:

Overall reoperation rate in HA group was 5.05%, with total mortality rate being 7.4% compared to 6.5% of IF group. Out of 46 patients of screw fixation, the overall reoperation rate was 20% with 4 patients being developed avascular necrosis and 13 being developed nonunion, and rest of the patients have average Harris hip score of 60–65 with 34%, while patients having poor Harris hip score compared to those of HA with Harris hip score of 80–90 with 88.2% having excellent to fair.

Conclusion:

Hip arthroplasty as compared to Internal fixation for the treatment of femoral neck fractures significantly reduces the risk of reoperation at the cost of higher superficial infection and blood loss. Furthermore, postoperative function as evaluated by the Harris hip score was significantly higher in the arthroplasty compared to the IF group up to the 6-month evaluation.
Spring Plate for Fixation of Comminuted Posterior Wall Acetabular Fractures
Authors: Gaurav Ashwini , Kumar Kaushlendra , Singh Ranjit Kumar
Published: March 2022

Introduction:

Comminuted posterior wall acetabular fractures always remain difficult and challenging to assemble and stabilize with surgical management without any intraoperative or postoperative complications and satisfactory functional outcomes. Hence, correct selection of implant and correct technique are always key steps in the surgical management of comminuted posterior wall fractures of the acetabulum.

Methods:

We performed a retrospective observational study on 16 patients that were operated between July 2016 and December 2017 at Patna Medical College and Hospital, Patna. Medical reports of all patients with comminuted posterior wall fractures operated with locally crafted spring plates placed under 3.5 mm pelvic reconstruction plates were evaluated radiographically and with the past Harris Hip Scores (HHSs).

Results:

The average follow-up was of 15.8 months, and there were no occurrences of implant migration, loss of reduction, or joint incongruity. One patient had developed a superficial infection that was treated with dressings and oral antibiotics. Two patients had preoperative sciatic nerve palsy, which improved gradually over the course of 3 months. No instances of hip arthrosis or osteonecrosis were found. Thirteen patients scored excellent, whereas three scored good on the past HHS records.

Conclusion:

Our study strongly supports the concept that locally crafted spring plates placed under 3.5 mm pelvic reconstruction plates are a good fixation strategy in the management of comminuted posterior wall acetabular fractures.

OBJECTIVES:This study explored the association between dietary and suicidal behaviors of Korean adolescents and investigated differences in this association in children of immigrant parents.METHODS: The sample (n=368,138) was collected from the Korea Youth Risk Behavior Survey from 2015 to 2020. Participants who agreed to provide family information (n=313,689) were classified according to their parents’ nationality. The study variables were 11 self-reported dietary behaviors, and their composite dietary behaviors (i.e., nutrient deprivation and unhealthy food consumption) that resulted from principal component analysis. The association between study variables and suicide-related outcomes (i.e., suicidal ideation, suicide planning, and suicide attempts) was analyzed by multiple logistic regression with adjustment for covariates. Adjusted odds ratios (aORs) and 95% confidence intervals (CIs) were calculated.RESULTS: Participants who skipped key meals and foods were more likely to have attemped suicide (aOR [95% CI]: skipping breakfast ≥5 days/wk, 1.28 [1.21 to 1.35]; consuming fruits <1 times/wk: 1.42 [1.32 to 1.52]; consuming vegetables <1 times/wk: 1.72 [1.53 to 1.93]; consuming milk <3 times/wk: 1.07 [0.99 to 1.16]). The associations were prominent in third culture kids (TCKs) (aOR [95% CI]: 2.23 [1.61 to 3.09]; 2.32 [1.61 to 3.35]; 2.63 [1.50 to 4.60]; 1.69 [1.09 to 2.63], respectively). Participants who consumed unhealthy foods (fast food, caffeinated and sugary drinks) more frequently were more likely to have attempted suicide (aOR, 1.55; 95% CI, 1.38 to 1.73). This association was also more prominent in TCKs (aOR, 2.08; 95% CI, 1.08 to 4.01).CONCLUSIONS: Our findings indicate a positive association between unfavorable dietary behaviors and outcomes related to suicide, and this association appears to be notable in adolescents with immigrant parents.
El discurso fotográfico en los premios World Press Photo (1955-2021): tecnología, política y medios
Authors: Blanco Pérez Manuel
Published: March 2022

Introducción: El vínculo entre periodismo y fotografía es muy fecundo y buena parte del establishment fotoperiodístico internacional gira, desde hace décadas, no tanto en torno a los rotativos como en torno a estos premios internacionales. De todos ellos, el más prestigioso es el World Press Photo, que en 2021 ha cumplido 66 ediciones. Metodología: Nuestra propuesta indaga en la evolución del discurso fotográfico de estos premios a lo largo de los años, y para ello hemos recopilado y filtrado por criterios técnicos las obras ganadoras de todas las ediciones, y las hemos analizado a partir de un sistema basado en ocho variables (algunas de las cuales han requerido de software, como la colorimetría y las dominantes de color). Resultados: Independientemente de la tecnología y las tendencias estéticas durante estas siete décadas de premios, hay patrones como el tipo de plano, el tipo de posado o los encuadres que se repiten con insistencia, además de una colorimetría muy recurrente. Discusión: en un contexto mediático muy tamizado por la tecnología y la reformulación que ésta ha propiciado en la fotografía, el discurso fotográfico de los WPP sigue fiel a una visión institucional muy vinculada a la política mundial. Conclusiones: Tras el análisis de las 66 piezas ganadoras concluimos que la fidelidad a su discurso visual en el World Press Photo –con las implicaciones que esto conlleva– está por encima de la libertad visual y creativa de los fotorreporteros y su adaptación al contexto histórico, político y social en que se fotografió.

Background: Studies showed olfactory disturbances in COVID patients. This has attracted focus of clinicians as an easy clinical screening tool in suspected population. Material and methods: 70 mild and moderate category COVID-19 RT-PCR positive patients, more than 10 years of age were tested on day of admission for olfaction with serial dilution of n-butanol and asked to grade severity of their olfactory dysfunction according to visual analogue score from 1-10. Results: Fatigue 42 (93.33%), sore throat 37 (82.22%), fever 36 (80%) and dyspnea 23 (51.11%) were the most common symptoms in moderate patients. Diabetes, hypertension and allergy were the three prominent risk factors. At time of admission, n-butanol diagnosed 20 patients having olfactory dysfunction compared to 11 by VAS. Patients tend to grade their dysfunction higher on VAS whereas the n-butanol test classified their olfactory dysfunction lower. Viral load and high CRP were not found to be significantly related with olfactory dysfunction. d-Dimer and LDH levels were found statistically associated with higher grading of olfactory dysfunction detected by n-butanol. Conclusion: The majority of cases developed hyposmia before they were admitted to hospital even before they realized that they were having hyposmia as revealed by n-butanol testing. We should go for objective tests of olfaction.
Competitive Location: New Models and Methods and Future Trends
Authors: Fernandez Jose , Redondo Juana L. , Ortigosa Pilar M. , Arrondo Aranzazu G.
Published: March 2022

Two new models for sitting a new facility in a competitive environment are introduced. Both the location and the quality of the new facility are to be found, so as to maximize the profit obtained by the locating firm. The patronizing behavior of customers is assumed to be probabilistic, i.e., they split their demand among all the existing facilities in the area, proportionally to the attraction they feel for them. The attraction is determined both by the distance between the demand point and the facility and by the quality of the facility. Contrarily to what is commonly done in literature, the demand is not fixed, but varies depending on the location of the facilities. The first model assumes a static scenario, whereas in the second one a competing chain reacts by location a single new facility too, leading to a Stackelberg (or leader-follower) problem. The new continuous location models lead to hard-to-solve global optimization problems. A new evolutionary algorithm called UEGO was used to deal with those problems. The computational results showed its usefulness and robustness. Parallel implementations of UEGO are also presented to cope with large instances. The efficiency and scalability of the parallel algorithms were shown through a computational study. Future trends which will allow the construction of an expert system for facility location are also discussed.
Wage Distribution Models

Published: March 2022

In our article we try to contribute to the discussion of the possibility to predict the trend of the wage distribution. For this purpose we use data from Czech Republic. But our model is useable for all similar data types. Classical models use the probability distribution such as lognormal, Pareto, etc., but their results are not very good. We suggest using a mixture of normal probability distribution (normal mixture) in our model. We focus mainly on the possibility of constructing a mixture of normal distributions based on parameter estimation. We estimate these parameters on the basis of their evolution in time. We work with data collected in the last 15 years. The data are divided into groups with respect to sex, age and regions.

Published: March 2022

Subject of this analysis is a contract of lease under the Serbian Civil Code (1844). The definition of the contract of lease encompasses two contracts: contract of service and contract of work.The contract of lease had been using also as anemployment contract until 1910, except for an artisans and merchants. The employment contract for an artisans and merchants was regulated by a guild decree (1847). When the labor law (1910) was passed in Kingdom of Serbia, the lease no longer had the function of an employment contract.

Although, formally speaking, the activities of social work centers are secondary and accompanying in relation to the activities of the bodies of the criminal justice system, their potential contribution to the prevention of domestic violence is essential. To repressive measures, which like are criminal law measures in their essence, the activity of social work centers gives a sense of prevention. The analysis of the role of these centers in the system of prevention of domestic violence indicates that the Law on Prevention of Domestic Violence did not adequately include programs of work with perpetrators of violence in the system of prevention of domestic violence and thus did not use the proven potential of social work centers to contribute to the prevention of this form of violence through psychosocial treatment of perpetrators. As in the normative sense the space for the application of psychosocial treatment of perpetrators in criminal legislation is very narrow, and in practice further reduced due to the limited application of appropriate legal institutes, social work centers, despite professional training and encouraging positive results, found themselves in a situation where in the system of prevention of domestic violence they cannot provide the necessary services.

The subject of this paper is the overview of what constitutes meeting one of the requirements for exercising the patient’s advance directive - its applicability in relation to the proposed medical treatment, as well as the overview how the change of circumstances can impact its effect. The author of this paper finds that the clarification and concretization of a medical treatment which a patient may or may not accept in advance is the key prerequisite of its future applicability and of consistent respecting of the individual's autonomy and his right to self-determination The author advocates the appreciation of the impact which the change of cisrcumstances may have on valid advance directives and raises some significant issues related to this topic: what is a relevant time frame for taking into account their effect, what kind of change of circumstances can lead to not respecting the patient's directive, how to proceed when the wish of the patient incapable of giving an informed consent is different from his will expressed in the advance directive, what is the significance of including the third person who will on behalf of the patient communicate with the doctor in relation to the application of the advance directive. In the concluding remarks the author states that the susceptibility of patients' advance directives to the influence of changed circumstances reflects on their binding nature and that this mechanism of decision making plays a restrictive role in the treatment of the patients incapable of giving an informed consent.
