This paper discusses the modelling and simulation of a Solar Photovoltaic (SPV) grid integrated system using parallel topology to accomplish load demand. Maximum Power Point Tracking (MPPT) control is employed for the determination of maximum power level under variable solar radiation and ambient temperature levels. Proportional Integral (PI) type voltage and current controllers have been employed for generating a required switching control signal. Under changing environmental conditions, Perturb & Observe (P&O) MPPT algorithm tracks the DC reference signal and controls the current regulator to obtain the maximum power from SPV array. It has been found that MPPT control tracks the maximum DC link voltage around reference value even under dynamic conditions. Voltage and current measurements have been performed at various Point of Common Couplings (PCCs) under changing environmental conditions. Voltage Source Converter (VSC) and utility grid values have also been compared. MATLAB results obtained through two case studies justify the implementation of our proposed system which is beneficial for research engineers working in various power quality assessment studies.

Purpose – There are few studies that have studied the relationship between Transformational leadership (TL) and organisation commitment (OC), but there are very few studies on the service sector especially in the Indian context. This study aims to fill the gap in literature by empirically examining the impact of four dimensions of TL using Multifactor Leadership Questionnaire (MLQ) on the Affective Commitment (AC) of the employees, within the context of the service sector in Bengaluru. Design/methodology/approach – A total of two hypotheses were proposed for testing transformational leadership using Multifactor Leadership Questionnaire (MLQ) questionnaire, (Bass and Avolio, 1997) and five items of affective organization commitment developed by Allen and Meyer (1996) was used for affective commitment. The questionnaire was administered to 210 employees working in various industries in the service sector in Bengaluru to measure the impact of TL on the AC of the respondents. Findings – The analysis of the data collected shows that TL has a positive impact on the affective commitment of the employees. In particular, the results of an empirical investigation revealed that individualized influence and individual consideration by the transformational leader had a significant impact on the affective commitment level of the employees. The employees in the hospitality industry had a difference in opinion compared to IT, Banking & education sector employees on the intellectual stimulation by the leader and their affective commitment towards the organization. Originality/value – This paper contributes to the existing literature of leadership and OC by providing practical evidence leading to the improvement of information and the understanding of the relationship between TL and AC.

De-noising of electrocardiogram signals is of utmost importance to diagnose the cardiovascular diseases. Many techniques have been utilized for filtering and removing noise from the raw electrocardiogram signal, such as traditional Wiener methods, neural networks and wavelet decomposition methods. These methods may lead to reduction in the amplitude of the QRS complex. The recorded multichannel electrocardiogram signal is correlated and is difficult for analysis. A suitable technique to overcome these problems is the appropriate use of Independent Component Analysis to maximize the required statistical parameters to make the output to be correlated. This work relates the performance of three of the Independent Component Analysis Algorithms such as JADE (Joint Approximate Diagonalisation of Eigen Matrices), Fixed Point ICA (Fast ICA) and AMUSE (Algorithm for Multiple Unknown signals Extraction) by which the three channel signal was made uncorrelated so that the best signal among the three different channels can be identified for further processing based on the values of the Signal to Interference Ratio(SIR) obtained in each of the algorithm

This work deals with investigation of effectiveness of adsorption and coagulation on removal of color of simulated acid dye solutions. Dye stuff belonging to acid group is employed and batch tests were conducted with three coagulants (Calcium hydroxide, Ferric sulphate and Aluminium chloride) to access feasibility and also to study the optimum values for coagulant dosage, RPM, pH and time. The study clearly indicates that dye effluent responds effectively to Ferric sulphate. The removal is probably due to physicochemical mechanism of coagulation and flocculation and/or chelating complexation type reactions and color removal at lower pH ranges may be either due to physicochemical coagulation or chelating complex formation reactions. The study clearly indicates that there is significant reduction in the chemical dosage requirements and in some cases a further increase in color removal. From the above studies it may be concluded that some of the Acid dye stuffs are suitable for their color removal using various coagulants. In this study we have used commercial carbon as well as activated carbon prepared from sawdust (agriculture waste), and performed the same experiment by varying the variables (coagulant dosage, RPM, pH and time), the studies shows that in the process of coagulation the percentage color removal is more than when compared to that of adsorption.

Rate-time decline curve analysis is a major technique which is mostly used in petroleum engineering. Many methods are used for the determination of the decrease in the production rate within a given period of time. The main disadvantage of Arp’s decline type curve analysis is that it is only used for boundary dominated flow period; it is not used for transient flow period. The analysis of the Fetkovich is to determine the log-log type curve for both the transient flow period (early time period or infinite) and boundary-dominated flow period (late time period). Arps developed the type curve which shows the production rate decline with time for the finite reservoir or late time period. The exponential or constant flow decline, hyperbolic decline, and harmonic decline according to the value of decline curve exponent (b) is given by Arps. After that Fetkovich improved on earlier work done by Arps in predicting decline production rate of wells over a given period of time. The main objective of this study was to plotting the rate transient analysis curve. I will plot the Fetkovich type curve (combined early and late times region). The graph will be plotted between the dimensionless decline flow rate (qDd) and the dimensionless decline time” (tDd). This will be the objective of the study.

The onion powder with initial moisture content of 10% (db) in form of thin infinite layer of thickness 5mm was dried using a laboratory microwave oven at 50W/g microwave power density to final moisture content of 2% (db).The temperature, moisture change pattern of the experimental process was monitored. Computer simulation of the predicted temperature pattern with drying time was obtained by using the mathematical model governed by energy balance equation and using data of the thermo-physical properties of the onion powder obtained either experimentally or through literature review. The usage of high microwave power to mass ratio results in raised temperature with reduced drying time. The decrease in drying rate is due to initial moisture content. Effective moisture diffusivity increases with decreasing moisture content due to the application of high power density. Lethality values for Escherichia coli, Bacillus cereus spores and Staphylococcus aureus, which are more prominent in onion powder, were then evaluated from the simulated temperature curve. DT and z values were used to estimate the sterilization values for each individual microorganism. It was observed that significant sterilization of E.coli and S.aureus start after 35 s at a minimum temperature of 89oC with 0.047 and 0.044 log reduction while, for B.cereus it starts after 75 s at 117oC with 0.431 log reduction. The maximum temperature of 117ᵒC was limited due to unacceptable sensory quality of end product.

Rainfall is the precipitation amount that is falling from clouds. In extreme conditions, rainfall could arise many problems. It is the leading cause of landslides and flood disasters. In D.K.I. Jakarta, the capital city of Indonesia, rainfall intensity plays a very vital role since it could easily be puddled and caused floods in many areas. Therefore, in this study, we try to make a rainfall intensity prediction in Central Jakarta using a very popular forecasting method, i.e., the Single Exponential Smoothing (SES). Based on the experiments conducted using Phatsa, it can be concluded that the SES method has been successfully used to predict rainfall intensity. However, it cannot give a very good prediction result due to its high forecast error values.

Education benefits a person in sustaining his present and future by assuring the goal of life. At present universities and colleges are mainly focusing to improve the academic performance of the students. Recently, many studies have concentrated on employing several machine learning models in the field of higher education to assist both the teachers and the students to identify their problems and can take remedial measures to improve their performances. Some of the earlier studies have been discussed about class imbalance problem and achieved poor prediction outcomes due to low performance of the classifiers. In this paper, we aim to improve the classification/prediction outcomes with a rule-based ensemble model based on various sampling strategies by addressing the class imbalance problem. The dataset used for this study has been collected from Vignan’s Lara and Vignan’s Nirula institutions based on considering various factors such as Attendance Percentage, No of Backlogs, Adjustable Nature, Concentration, Result History, Discipline in class, Usage of Social Media, Degree of Intelligence, Understanding of Subjects, Event Participation, Time Management, Extra Classes, Alternative Learning Skills, Logical Thinking, Bad Habits, Parents Education, Health Condition, Planning for higher studies, Family Support, Time Management, and Aggregate. To evaluate the efficiency, we also considered and compared our original dataset with different benchmark datasets and the performance measures of the proposed method is also tested with various sampling methods based on a learning rate parameter ranging between 0.1 and 0.8. The original data set with the re-sampling method with the proposed method achieved maximum precision values at a learning rate 0.3 with an accuracy rate of 98.36%. Finally, the obtained results were also compared with several baseline classifiers like Naïve Bayes, SVM, MLP, KNN, and OneR on the collected original datasets.

This study describes the development of a line follower robot for a surveillance camera monitoring system. An effective closed loop control fuzzy logic algorithm is used to constantly correct wrong movements of the mobile robot using a feedback mechanism. The robot senses a black line on a white surface and endeavors itself accordingly to follow the track. A manual navigation system has also been designed to overrule the automatic navigation control of the robot to reposition itself back on the track whenever it strays from the path unintentionally. The fuzzy controller algorithm is an advanced method to ensure the line follower robot moves accurately on the track. It is a replacement control technique of traditional switching method. To fuzzifying the digital input data of four infrared sensor that detecting the line, the data is converted into error and delta error that represent the current and previous position of the robot relative to the line that it follows. There are nine base rules that have been created with two inputs which are error and delta error to the robot direction whether to go to the right, move forward or to the left. Then, for defuzzification, center of sum and centroid of area method have been used to calculate the defuzzied value using trapezium area formulae. Based on the comparison between both control techniques, it is found that the line following surveillance robot with fuzzy logic controller works faster than conventional switching method to complete the same task with the average oscillation length using the fuzzy logic controller is reduced to half.

PLACENTA ACCRETA - A MANAGEMENT ENIGMA
Authors: Bawankule Bhakti , Patra Sushree , Kumar Sushil
Published: December 2019

AIMS AND OBJECTIVES: 1. To analyse maternal and foetal outcomes 2. To analyse types of
interventions.
MATERIALS AND METHODS: It is a retrospective study conducted over a period of 3years (Jan2017-August 2019), in
Department of Obstetrics & Gynaecology at our hospital. Out of 9000deliveries conducted in 3years, 12patients were found to
have accreta during caesarean section. Cases were analysed for interventions and maternal and foetal outcome.
RESULTS: The mean age of patient included was 25.7yrs ranging from 21-35 yrs. 7patients were gravida 2, 3were gravida 3 and
2 were gravida 4. The mean gestational age was 34.4 weeks ranging from 27.1 to 37.5 weeks. History of D&C was present in
1case, H/O previous LSCS was present in all cases, H/O placenta previa in current pregnancy was present in7/12 cases. H/O
previous caesarean section with placenta previa in this pregnancy was present in 7cases. Hysterectomy alone was done in
9patients. Hysterectomy with Internal Iliac Artery Ligation was done in 3patients. Average blood loss was around 1700 ml &
blood transfusion was required in all patients. Total 6 patients required ICU care, with 1maternal death and 2 IUFD.
CONCLUSION: Antenatal diagnosis of placenta accreta is a challenge. With increasing frequency of previous caesarean
section and placenta previa the prevalence of placenta accreta is increasing. With advent of newer interventions and
availability of interventional radiologists death due to massive haemorrhage is reducing. Obstetric hysterectomy and Internal
Iliac artery Ligation still remains the mainstay of treatment. However, morbidly adherent placenta is a threat to both patient and
obstetrician.

SAFETY COUPLINGS WITHIN MECHANICAL TRANSMISION
Authors: Ioan Stroe
Published: December 2019

The paper presents the constructive and functional generation of elastic and safety couplings. The
method of structural and constructive generation of these couplings is presented. Starting from the
mechanic coupling scheme, the following dynamic analysis algorithm is proposed: formulation of problems from dynamic
modelling; kinematic and static modelling of elastic and safety couplings; modelling the induced correlations of the mechanical
characteristics of the engines and effector; modelling the semi clutches movement using Lagrange educations - species II. The
proposed algorithm is veried by the exemplication on a coupling realized and subjected to variable requests and to the
constructive and functional deviation. The conclusions obtained highlight the role and importance of elastic and safety
couplings in the eld of mechanical transmissions

Mucocele is dened as mucus-lled cavity, which can appear in the oral cavity, appendix, gallbladder,
paranasal sinuses, and lacrimal sac. They are mostly benign and self-limiting nature. The lesion is
formed when the main duct of a minor salivary gland is torn followed by extravasation of the mucus into the brous connective
tissue so that a cyst like cavity is produced. The most common site of occurrence is lower lip and most probably affects the young
patients. These are soft, uctuant, transparent cystic swelling of deep blue colour. Surgical removal of the mucocele is the
treatment of choice. This paper reviews the Mucocele and presents a case reports.

El síndrome cardio-facio-cutáneo es una entidad clínica y genéticamente heterogénea, perteneciente a un grupo de síndromes conocidos como RASopatías. Este trastorno es de baja prevalencia, con alrededor de 200 a 300 casos en el mundo, e incluye entre sus manifestaciones clínicas rasgos faciales dismórficos, defectos cardíacos y alteraciones cutáneas. Los hallazgos fenotípicos del síndrome cardio-facio-cutáneo que se comparten con otros síndromes y la ausencia de criterios diagnósticos o signos patognomónicos lo convierten en un reto diagnóstico. En este manuscrito se presenta un caso confirmado de síndrome cardio-facio-cutáneo por estudios de genética molecular en una paciente de siete años de edad, mediante el cual se exponen las principales características de esta condición.

Introduction: Left atrial myxoma is a rare benign tumor. It can be an embolic complication such as an ischemic stroke.

Case presentation: It was a 48 years old patient who was referred to our unity for the etiological investigation of an ischemic stroke. She did not have personal medical and surgical history. She had a recent right hemiplegia. The cardiac auscultation found a mitral diastolic murmur. The brain CT showed a recent ischemic stroke in the superficial and deep left sylvian territory. The transthoracic echography revealed a myxomatous mass, responsible of an obstacle of the left ventricular filling. Anticoagulation by antivitamin K (AVK) had been initiated and a resection of the mass indicated.

Conclusions: The left atrial myxoma is a rare benign tumor whose mode of revelation can be an embolic complication. The Echocardiography is reference imaging modality in diagnosis with a high sensitivity.

Nas últimas décadas, muito tem sido estudado sobre o bem-estar e a abordagem da Psicologia Positiva influenciou o campo dos estudos, especialmente sobre gestão de pessoas e comportamento organizacional, fortalecendo o foco com perspectiva centrada na pessoa. Aliado a esse marco teórico, algumas mudanças pontuais na natureza e no contexto do trabalho apoiam a necessidade de um maior foco no bem-estar. Esse constructo psicológico multidimensional pode envolver componentes, tais como, a satisfação e o envolvimento no trabalho. Trata-se de uma área de pesquisa que vem se tornando cada vez mais importante para saúde pública. Neste estudo, pretende-se lançar luz sobre o tema enfocando conhecimentos sobre o que antecede e sobre as consequências pontuais a respeito do bem-estar no trabalho. Espera-se contribuir teoricamente com esse campo de estudo discutindo-o em diferentes vertentes, permitindo entender melhor o bem-estar no trabalho. Importante se faz destacar que, ele reflete eventos amplos ocorridos na sociedade, a partir de um olhar externo e reflete a atuação da área de Gestão de Pessoas. As pressões no trabalho e na sociedade em geral estão criando uma ameaça crescente ao bem-estar dos funcionários, tornando necessária a atuação mais contundente dessa área. Evidencia-se na literatura e na realidade organizacional a carência de uma abordagem alternativa, a qual a gestão de pessoas priorize práticas destinadas a melhorar o bem-estar, acarretando uma relação de emprego positiva. Em outas palavras, a área de gestão de pessoas ainda não atua efetivamente com foco no bem-estar no trabalho, por negligenciá-lo ou desconhecer seus efeitos.
Modificación de la conductividad eléctrica de tinta comercial para impresión inkjet utilizando nanotubos de carbono multipared

Published: December 2019

The electrical conductivity of the black commercial ink was modified by introducing multi-walled carbon nanotubes (CNTs) in percentages of 0.5 to 1.5% by weight. The carboxylic groups, present on the surface of the CNTs, were sufficient for the dispersion of the nanostructures to be adequate in the ink. In addition, no incompatibility was distinguished between the CNTs and the ink components. In fact, a synergy between the black pigment and CNT could be observed. The application of the ink using the modified corrector pen made it possible to obtain uniform lines on ordinary paper based on cellulose fibres and on photographic paper. The patterns drawn by hand with the best conductivity were those made on ordinary paper and whose CNT content was equal to or greater than 1% by weight.
Professional Identity and Performance of English Language Teacher Trainers in Bangladesh: In Quest of the 'Self'

Published: December 2019

The English language teaching (ELT) sector in Bangladesh is expanding rapidly and has undergone huge reforms in the curriculum, textbooks and assessment format in recent years. This has called for developing a cadre of quality English teachers at secondary and higher secondary education sub-sectors through in-service teacher training. As a result, English language teacher training has emerged as a relatively new but an important profession in Bangladesh. However, the recruitment, employment and professional development of young ELT practitioners who serve as English language teacher trainers(ELTT) in government run ELT projects and teacher training institutions are characterised by inconsistency in professional structure, lack of policy formulation and disparities in job status. This paradoxical reality has spawned a rather complex setting for the young ELTTs as they struggle to negotiate and construct their professional identity. This research explores the nature and causes of Bangladeshi ELTTs identity formation and seeks to identify links between identity formation and professional performance of ELTTs who worked in two organisational settings in Bangladesh. It explores and reports how Bangladeshi ELTTs perceive their identity within and out of the professional community and how their professional identity affects their professional performance. Data were collected adopting a mixed method approach through questionnaires and in-depth interviews of selected teacher trainers from two major government training providers in Bangladesh. The findings reveal that identity of ELTTs purports complex, relational and multiples realities underpinned by recruitment process, professional status and job satisfaction. Although same or similar factors contribute to identity formation of ELTTs, there is inequality, hidden discriminations, identity gaps and crisis among trainers.
