Authors: Varsha Laxman Jakune  , Varsha Siddheshwar Tegeli  , Misbah Sultana Abdul Kausar Badewale
Published: January 2023

The reviewed work addressed the shift in focus from conventional polymers to bio-based and renewable polymers. This extensively discussed the values of various fatty acid components present in the oils and polymers. Areas of application of the thermosetting polymers obtained from plant seed oils were discussed. Non-biodegradable polymers are causing severe damage to the environment. To counter this, need of biodegradable polymers is gaining a rapid growth in numbers, in their applications and quantities used. In this manuscript, we have briefly described important vegetable oil derived materials such as alkyds, poly-esteramides, , polyurethanes, epoxies, polyols, along with their preparation and applications as protective coatings. A small portion of the review is also dedicated to the future perspectives in the field. In spite of their extensive utilization in the world of coatings, literature survey revealed that in the past no review has come up describing the chemistry and applications of vegetable oil polymer based coating materials. In addition, due to the oil crises worldwide, focuses from synthesizing polymers from petroleum has shifted to the synthesis of polymers from renewable resources such as vegetable oils. The use of vegetable oils in the polymer renders biodegradability to the polymer. Different researchers have used different vegetables oils like castor oil, soybean oil, & sunflower oil for synthesis of polymers and utilized them in diverse fields like biomedical, coatings, adhesives, and as structural materials. This review discusses the synthesis, characterization, degradation and applications of polymers obtained from natural oils such as castor oil, soybean oil etc.
Ayurvedic management of Vatarakta with special reference to Gout: A Case Study
Authors: Sachinkumar Sahebrao Patil
Published: January 2023

Vatarakta is a disease explained in Ayurveda involving Vata Dosha imbalance affecting Rakta Dhatu, where the Vayu gets aggravated due to long distance rides on animals like elephants, camels, horses, and on the other hand Rakta or blood gets vitiated by the consumption of Lavana, Amla, Katu, Kshara etc. The Vata, whose passages are blocked by Rakta further undergoes vitiation and further contaminates the Rakta or blood. The blood vitiated by Vayu later burns the whole blood in the body and later gravitates towards thefoot. This vicious amalgamation of vitiated Vata and Rakta is called Vatarakta. Vatarakta can even be correlated to Gout on the basis of etiopathology. A 45 years old female patient approached the OPD with the chief complaints of: Right great toe pain, swelling along with discoloration. Right ankle joint pain, swelling along with burning sensation of b/l sole. Right wrist joint pain along with difficulty in movements & Generalised weakness was also seen. All the above complains were since 4 months. The patient was given completely Ayurvedic medicines such as Kaishor guggul, Amrutadi guggul, Sanshamani Vati, Guduchi kwath for oral consumption & Pinda Tail (Sukhoshna) for local application & sarvanganadisweda with dashmool kwath for 2 months, follow up was taken on every week for 2 months. The results were remarkably seen. Hence this study was taken to prove that Ayurvedic management has remarkable results in Vatarakta (Gout).

Published: January 2023

According to the World Health Organization, breastfeeding is a natural way to provide nutrients that are very beneficial for the growth and development of babies. Breast milk is the best nutrition that babies need because it contains various substances and antibodies that can increase the body's immunity so it can become a protector (immune) for babies from all types of infections. During the COVID-19 pandemic, WHO and UNICEF suggest breastfeeding even if the mother is COVID-19 suspected/confirmed. The benefits of breastfeeding outweigh the risks of transmission. However, the infection prevention and control must be strictly applied when breastfeeding. This study aims to describe the success of breastfeeding in infants aged 6-12 months born to mothers positive for COVID-19. This research used a quantitative descriptive study design with a cross-sectional approach. Questionnaires were given to 76 mothers with a positive history of COVID-19. The data analysis used was univariate. The results showed that the majority (67.1%) of mothers with positive COVID-19 had received communication, information, and education (CIE) while being treated at the hospital. Most (59.2%) of COVID-19-confirmed mother unable to provide exclusive breastfeeding to their babies. Majority (89.5%) of them have implemented health protocols when breastfeeding well. There was no COVID-19 vertical transmission from mother to child during delivery or breastfeeding in 89.5% and 93.4% subjects, respectively.

Published: January 2023

Purpose: This study aims at evaluating the excess absolute risk (EAR) of cancer in thirty patients with high and intermediate risks of prostate cancer based on the Amico’s classification, who received a three-dimensional conformal radiotherapy (3DCRT) or a modulated volumetric arc therapy (VMAT) with 6 MV photons energy. Materials and Methods: VMAT plans were performed in simultaneous integrated boost, with 76 Gy to prostate and 56 Gy to pelvic lymph node and seminal vesicle. 3DCRT planning was realized in two stages with prostate, seminal vesicles, and pelvic lymph node receiving 46 Gy, in the first stage, and in the second stage, prostate prescribed at 28 Gy. The EAR was assessed using the Schneider concept based on the equivalent dose for a given organ (OED). Thus, the EAR of the rectum, bladder, pelvic bone and healthy pelvic tissues were calculated and compared on the basis of the Mechanistic, Exponential Linear, Plateau and Sarcoma specific Mechanistic models. Results: The EAR in the rectum were found to be higher in 3DCRT than in VMAT. The EAR values ranged from 3.98-5.37 for the rectum, and from 1.05-3.76 for the bladder depending on the model used. Conclusion: The overall EARs analysis for both radiation modalities indicated that the risk of induction of carcinoma in the rectum was higher with 3DCRT, compared with VMAT. However, it would be necessary for validation of predicted models, to conduct prospective clinal trials with a larger patient cohort

Published: January 2023

In clinical practice, heart failure (HF) and renal impairment are coexisting illness which is linked with one another. Heart and kidney have bidirectional inter-relationships, and it has been suggested that the kidney is the most significant organ involved in acute HF. The "cardio-renal syndrome" (CRS) is defined as acute or chronic malfunction of one organ causing acute or chronic dysfunction of the other [1, 2]. Furthermore, renal failure in HF can lead to decreased diuretic efficacy, diuretic resistance, congestion worsening, and further deterioration of renal function, creating a vicious cycle. In patients with acute HF, renal impairment is also a powerful independent predictor of short-term and long-term prognosis [3 - 9]. Renal hypoperfusion caused by inadequate cardiac output and over diuresis has long been thought to be the etiology of CRS. However, research has progressively shown a relationship between venous congestion and CRS, rather than inadequate cardiac output, correlating the failing right heart to CRS in recent decades. Indeed, both RHF and CRS have complicated and intertwined pathophysiologies that may affect several organs and systems in addition to isolated heart and kidney disease. This study focuses on the pathophysiology of RHF and cardio-centric phenotypes of CRS ("Type 1" and "Type 2"), as well as treatment options.

Published: January 2023

O trabalho objetiva analisar as diferentes formas de privatização da educação básica ocorridas no Chile e no Brasil. Trabalhou-se com pesquisa bibliográfica e documental, a partir da análise das Constituições e da legislação educacional vigentes nos referidos países. Os resultados apontam que a educação no Chile esteve predominantemente controlada pela iniciativa privada enquanto resultado da reforma neoliberal da década de 1980 e favoreceu sua total subordinação às leis do mercado, em processo de privatização da educação. O caso brasileiro está marcado por processos de privatização na educação, quando o fundo público é disputado por diferentes atores dos setores público e privado, quando estes últimos se apresentam, predominantemente, enquanto parceria público-privada e inserem, nas políticas públicas educacionais, a lógica do setor privado.

Authors: Utomo Budi Suryo , Wibowo Kartono , S Soedarsono
Published: January 2023

The successful construction of infrastructure is dependent on many aspects, including at least time, cost, and control. With good control, deviations during the execution of work are expected to be minimized. In the case of the "MAS BIMACIKA" Service Office Building Construction project, acceleration of construction becomes an issue. Acceleration needs more resources than normal conditions, the addition of resources is required to achieve productivity value as planned. This study aimed to examine time and cost performance in the "MAS BIMACIKA" Service Office Building Construction Project. The Earned Value Concept, and the Crashing and Overlapping method used to analyze the costs resulting from the acceleration of work, were adopted in the process of controlling. Budget Cost of Work Schedule, Budget Cost of Work Performance, and Actual Cost of Work Performance were the parameters of the study. From the results of the analysis carried out until week 5, it is observed that the work could be completed earlier. This condition is indicated by the value of BCWP which is higher than BCWS. However, from the cost perspective, the construction resulted in wastage. This finding is confirmed by the value as shown in BCWP which is below ACWP. The analysis results until the 10th week show that the work could be completed earlier. This finding is indicated by the value of BCWP which is higher than BCWS. In terms of costs, the contractors still gained profit. This statement is supported by the value of ACWP which is below BCWP.

Background: Predicting the undergraduate’s placement performance is vital as it impacts the credibility of educational institutions. Hence, it is significant to predict their performance based on placement in the early days of degree program. Objectives: The study intends to predict the undergraduate’s placement performance through the introduced ANN-R (Artificial Neural Network based Regression) as it is able to handle fault tolerance. For efficient prediction, relevant feature selection is needed that is performed by the proposed ILO (Improved Lion Optimization) algorithm as it has the ability to find nearest probable optimal solution. Methodology: Initially, the parameters and population are initialized. Subsequently, first best-agent is stated in accordance with fitness function. Subsequently, position of present search agent is updated. This iteration continues until all the features are selected and optimized result is attained. Here best score is computed using the proposed ILO for feature selection. Finally, the dropout analysis and placement performance of students is predicted using the introduced ANN-R through a train and test split. Results/Conclusion: Performance of the proposed system is analyzed in accordance with loss metrics. Additionally, internal comparison is performed to find the extent to which the actual and predicted values correlate with one another during prediction using the existing and proposed system. The outcomes revealed that the proposed system has the ability to predict the student’s placement performance along with domain of interest with minimum errors than the traditional system. This makes the proposed system to be highly suitable for predicting student’s performance.

Published: January 2023

In this paper we proposed a novel enhanced gate diffusion (EGDI) adder is designed and is implemented in Distributed Arithmetic (DA) based Finite Impulse Response (FIR) filter. Generally multipliers, adders and shift accumulators are the basic blocks present in the FIR filters. The hardware architecture of multipliers is very high. To get rid of this, multiplier less architecture are needed in FIR filter. So Distributed Arithmetic architecture place a key role in FIR filters which will occupy less area and increase the speed. To reduce the area further the adders in DA are designed using enhanced gate diffusion (EGDI) which increases the operation speed of FIR filter and at same time the area will be decreased. The proposed design is synthesized and implemented in Synapsis design compiler tool. The area, power delay product, frequency, area delay product and power of the proposed design are calculated. When we observe the synthesis results, the proposed design has 15% high frequency rate when compare with the existing design. Also the proposed design is more useful in signal processing applications like decision feed-back equalizer.
A Low-Complexity SLM PAPR Reduction Scheme for OFDMA
Authors:   Jawaharlal Nehru Technology University, Raveen P. , Kumari U.V. Ratna ,   Jawaharlal Nehru Technology University
Published: January 2023

In orthogonal frequency division multiplexing (OFDM) systems, selected mapping (SLM) techniques are widely used to minimize the peak to average power ratio (PAPR). The candidate signals are generated in the time domain by linearly mixing the original time-domain transmitted signal with numerous cyclic shift equivalents to reduce the amount of Inverse Fast Fourier Transform (IFFT) operations in typical SLM systems. The weighting factors and number of cyclic shifts, on the other hand, should be carefully chosen to guarantee that the elements of the appropriate frequency domain phase rotation vectors are of equal magnitude. A low-complexity expression is chosen from among these options to create the proposed low-complexity scheme, which only requires one IFFT. In comparison to the existing SLM technique, the new SLM scheme achieves equivalent PAPR reduction performance with significantly less computing complexity. MATLAB tool is used for simulating the proposed work.

The delivery of facilities management (FM) services through the Public-Private Partnership scheme has been increasing in recent years. The long-term success of this partnership depends mainly on the choice of the best-suited private partner. However, an issue regarding the unavailability of evaluation criteria was discovered when selecting the best FM service providers within this scheme. Preliminary research shows that evaluation criteria are the fundamental elements of the FM procurement process, yet little attention is given to this subject. The evaluation criteria are fundamental in choosing the most qualified FM service providers, especially ina complex project like PPP. Thus, this research aims to identify the evaluation criteria for FM through the PPP scheme. An in-depth literature review was conducted in this paper. The focus of the review was associated with the evaluation criteria of FM service providers in the PPP scheme. This paper identified four criteria that should be considered, namely clients’ requirements, external environment/factors, project characteristics, and financial advantages. The outcome of this paper can be used as a theoretical basis for the development of the FM procurement framework for the PPP scheme.

The cost of producing concrete has increased, and its effects on the natural environment have become apparent. The ideal solution is to use agro-waste material instead of cement in concrete. Palm oil fuel ash (POFA) is a by-product of the burning of waste material at the palm oil power plant. Looking at the utilization of POFA in concrete research, there has been study conducted on the behaviour of properties of normal strength concrete containing POFA in terms of compressive strength performance. However, the performance of ultra-high strengthconcrete produced using POFA is still lack. This research aims to determine how well POFA works as a cement substitute in ultra-high-performance concrete (UHPC).It also to determine the mechanical properties of ultra-high-performance concrete (UHPC) withPOFA addition. In this study, the percentage of POFA used as a cement replacement was 5%, 10% and 15% by binder weight. The results were collected from slump test and compressive strength test. Tabulation and graph illustration were the methods used to present the data. The workability test conducted showed that with the increase of POFA addition to the UHPC, the workability of fresh concrete was reduced. Meanwhile, the compressive strength at 28 days, UHPC with 5% of POFA addition showed the maximum valueof compressive strength at 84.12 N/mm2.

Healthcare organizations play an important role in people's well-being all over the world; good healthcare facilities are extremely beneficial in combating many diseases worldwide. Innovation is one of the most important factors influencing service quality in healthcare organizations worldwide, particularly in the UAE. The pandemic, changing human needs and globalization have made organizations more aware of the importance of improving patients' experiences through improved service quality and innovative services, which has become a winning strategy and provides organizations witha comparative advantage over others through customer confidence building. This research assessed mediating effect of service quality on health services innovation and outpatient experience. The model was developed with the help of SmartPLS software package and the data was gathered through questionnaire survey. Analysis of 397 questionnaire forms were used to analyze direct relations between service quality and service innovation with out-patient experience as well as indirect effect of service innovation on out-patient experience through service quality. The developed model was confirmed through convergent validity and discirminant validity. The R-square reveals that service innovation accounted for approximately 47% of the variation in service quality. While service innovation and service quality explained approximately 80% of the change in outpatient experience. This means that a unit change in both service innovation and service quality improves the outpatient experience by 80%.

Published: January 2023

In current competitive market, organisations strive not only to complete projects on time, but also to ensure stakeholder satisfaction. Creating a separate body or department for project management within an organisation is frequently motivated by a desire to improve project management and reduce projects that fall short of customers' and stakeholders' expectations due to budget overruns or intolerable delays. Thus, Project management Office (PMO) practises are becoming more popular around the world to support project management activities. Hence, this paper presents a qualitative approach by interviewing twenty experienced personnel who had worked with PMO for several years. The experts were from four organisation namely Masdar Abu Dhabi Future Energy Company, Al Mansouri 3B Group, Abu Dhabi Securities Exchange (ADX), and Gulf Falcon Company (GFC). These open interview sessions were to discover the success factors in implementing PMO in UAE organisation. The results of the interview found that there are six key factors affecting the effective implementation of the PMO which are project flexibility; politics and change resistance in stakeholders; alignment and accountability; efficient resources; risk management; effective leadership and team management. Project flexibility, as well as effective leadership and team management, are cited as the most critical factors by all respondents. The paper also incorporates an effective PMO framework which suggests various strategic measures to implement in five phases of the project lifecycle: initiation, planning, execution, monitoring and controlling, closing, and post-implementation reviewing.

This paper presents an experimental study to analyse the bonding strength between geopolymer concrete (GC) and normal concrete (NC) bond substrate. Three different strengths of GC which were 80 MPa, 85 MPa and 90 MPa were bonded to 30 MPa NC and denoted asNC30-GC80, NC30-GC85 and NC30-GC90. Slant shear and split tensile tests were conducted to investigate the bonding strength between two different substrates. The effect of bonding was then determined by using Mohr-Coulomb theory where critical bonding condition (smooth surface) was created. From the analysis, it was found that NC30-GC80 had the most powerful self-adhesion between GC towards NC. This result indicated the highest bonding strength of GC to NC at critical condition. Such strong bond was obtained by the effect of self-adhesive from GC to NC. The self-adhesive characteristic which represented by pure shear strength was obtained from Mohr-Coulomb theory.

The need for an emergency disaster management related to damhas risen up in recentyears. This is dueto uncertainties in global weather predictions which also affect local Malaysian area. With unpredictable prolonged rainy weather, concerns on events that could lead to flooding has triggered the authority to review the evacuation strategies in critical locations.This paper describes an investigation on the effect of early warning system and people response delayto the rate of fatality in the event of flooding due to dam breach. The Life Safety Model is utilized as a tool for the simulation of people vehicle and building response to 2D hydraulic flow of the river originated from the dam. The study area is based on KenyirDam and its surrounding vicinity. A number of scenarios are simulatednamely cases with and without early warning system. For the case with early warning system, different triggering time is also investigated. On top of that, the effect of people responsedelay to the warning system is simulated. It was found that early warning system plays a critical role in reducing the number of fatalities due to flooding. Equally important is the time taken for the community to start evacuating whentriggered by the early warning system.From the result LSM, optimum evacuation parameters could be identified and used for the purpose of design, planning and implementation of local emergency evacuation plan in the event of dam-related flooding.

Habermas’ (1974) concept of the ‘public sphere’ (öffentlichkeit) enabled the bourgeoisie to participate in the process of discussing social issues and making various decisions which were influential in the formation of the laws regulating social life. Same time, it is an important common educational tool. Although the public sphere refers to citizens expressing their idea in a society, the virtual sphere has rapidly moved on to the Internet environment using social media. Within the coronavirus disease (COVID-19) has spread to many countries and has been causing serious repercussions as a pandemic. The use of digital technologies has increased significantly during the pandemic, and they have helped transform people’s lives. In this context, Discussion of virtual sphere has also gained importance. Codification and personalization types of knowledge strategy will be followed in this study by conceptualizing a framework, which will be designed by understanding the virtual sphere in a society. There is still a literature gap the relationship between public sphere and virtual sphere as well as the lack of understanding for the integration of knowledge strategies (codification and personalization) with virtual sphere 1.0 and 2.0 in the context of tacit and explicit knowledge. The main problematic issue of this study revolves around how two type of knowledge strategies could be used by virtual spheres 1.0 and 2.0. Two propositions which will be expected to contribute to the literature were developed in the study to understand the roles of two types of knowledge strategies in relation to virtual sphere variants regarding the digital society and knowledge society.

The educational process requires learning methods, learning strategies, the use of appropriate methods, media and technological learning models, so as to create a pleasant learning atmosphere in all subjects and arouse the spirit of learning. To create a more lively learning atmosphere, teachers must be able to make learning in the classroom more enjoyable. The choice of learning approach is an alternative that can be taken. The contextual teaching and learning approach is a learning concept that helps the teacher relate the material he teaches to the student's real-life situation, and encourages the student to make connections between the knowledge he receives and its application in their lives (Musical). , 2007:41). According to Carlos, constructivism is a view of the learning process (acquisition of knowledge) that begins with the emergence of cognitive conflicts that can only be overcome through self-knowledge and at the end of the learning process, children build knowledge through. The purpose of this study is to find out and interpret the application of the approach used in learning in class VI SDIT Cendekia. The subjects in this study were teachers and students of class VI SDIT Cendekia totaling 24 students.

Published: January 2023

This research is motivated by the low interest in student learning in Social Sciences (IPS) subjects. This is due in large part to the fact that most social studies lessons are placed at the end of class, where at the end of the class students begin to feel lazy to study and also sleepy, besides that students are not able to answer the feedback given by the teacher about the material just being taught, students are less involved active in the learning process. Teachers who tend to use the lecture method because social studies studies talk a lot about theory, this makes students more easily bored following lessons and seems difficult to answer test questions. The formulation of the problem in this study is whether the application of cooperative learning through paired card media can improve social studies learning outcomes for students at MTs Raudhatul Akmal Batang Kuis, Medan.
