PARTY ACTIVISTS AND PARTY PROGRAMS AT GRASSROOTS LEVEL: THE INTERTWINED EFFECT
Authors: Wan Abdul Ghapar Wan Rohila Ganti , Che Mohd. Razali Che Hamdan 
Published: June 2020

Purpose of the study: This study explored how party activists retain their high activism with the party through their involvement with party activities. It also attempted to explore party programs at the grassroots level that helps maintain continuous grassroots support for the party. The strong symbiosis between party activists and party programs at the grassroots level was a secret formula to win elections.
Methodology: Being qualitative in nature, this study conducted in-depth interviews with thirty - two party activists. The PAS and UMNO party activists in Terengganu were selected as units of analysis using the purposive sampling technique. The interview data were thematically analysed through the content analysis method.
Main Findings: This study yielded that Community and Welfare programs, and Electoral Works were two impactful party programs to fish votes and maintain voters’ support at the grassroots level. On party efforts to maintain the motivation of its activists, this study found four main party programs namely internal programs, political training, involvement outside party, and joining special programs.
Applications of this study: This study concludes that ensuring party activists at their highest level of motivation by designing various programs are equally important with organizing party programs with the voters at local levels. When party activists are highly motivated, party programs at local levels would be successfully run, while organizing party programs at the local level without the presence of highly motivated party activists would be worthless.
Novelty/Originality of this study: Party activists are often neglected by party leaders, as much focus has been given to party manifesto, choosing winnable candidates, and encountering electoral issues. Neglecting party activists often leads to frustration, thus party programs cannot be properly organized without committed party activists.
A REVIEW OF PROMINENT MODELS OF TEAM ROLES AND CONCEPTUALIZING A NEW MODEL
Authors: Nair Divya , Rani N Meena 
Published: June 2020

Purpose of the study: This study aims to arrive at a new conceptual model of team roles that minimizes the weaknesses and maximizes the strengths of the prominent existing models. This study attempts to connect the new conceptual model of team roles with the five-factor model of personality.
Methodology: Prominent existing models of team roles were compared and contrasted amongst themselves. Each model was carefully studied to identify underlying strengths and weaknesses. A comprehensive list of team roles with definitions from each model was put together. The list was carefully examined to identify team roles that can be merged or eliminated. A new model was conceptualized by merging and eliminating team roles wherever necessary.
Main Findings: Each of the prominent existing models reviewed missed some critical aspects when contrasted with each other. There is a duplication of roles in some models while some important roles are missing in other models. A more comprehensive conceptual model has been proposed.
Applications of this study: The conceptual model proposed in this study can be further tested and developed to create team role inventories. This model can be useful for team building in organizations of all kinds. The model would help in identifying the right members for a new team as well as in predicting outcomes of intact teams.
Novelty/Originality of this study: The new conceptual model of team roles proposed in this study connects with the contemporarily relevant five-factor model of personality. This makes it different from previously existing models. The proposed model encompasses the strengths and avoids the weaknesses of past models.

Published: June 2020

This paper presents a vibration analysis of an internal alternative combustion engine through frequency analysis and wavelet transform, where a form study of the temporary signal and the energy of that signal is carried out to extract certain characteristic values that allow to differentiate and identify to which pre-established operating conditions, a specific vibration signal belongs. Software is used to make the data decomposition, analysis and value extraction. Different analysis results are presented on this investigation like frequency analysis, spectrogram analysis, wavelet analysis, cross wavelet analysis, and results validation by extracting values of the signals of two tests generating a variation chart showing runs variability if it is big o tiny variability. This analysis is performed to characterize the engine vibration signals so that it is possible to identify an incipient failure in a non-intrusive manner and optimize its maintenance. Also, it can be determined the repetitive form that describes a temporary signal of mechanical vibrations of a motor, if its work cycle it is considered to separate the temporary signal into sections, as long as there are no lower frequency components than the result of dividing the sampling frequency for the number of points that are in a work cycle (the limit frequency).

Authors: Alejos García José 
Published: June 2020

Este interesante libro es un tratado de historiade la etnografía en México y una síntesis de estudios etnológicos sobre cosmovisión mesoamericana. De entrada, considero que se trata de un aporte valioso para la historia de la antropología mexicana y sus instituciones, una obra que desde ya se perfila como una referencia obligada para las investigaciones sobre los dos grandes temas que la ocupan. Es un libro de un gran maestro de la antropología mexicana, y por lo mismo, con una definida orientación pedagógica, escrito con toda la intención de brindar una visión integral, así como datos concretos sobre los temas tratados; concebido para formar a las nuevas generaciones de estudiantes y para aportar de manera sustantiva a la consolidación de un pensamiento antropológico nacional. Es pues, en mi opinion, una importante contribución para las disciplinas científico-sociales y humanísiticas que se desarrollan en México y Centroamérica, y un texto de consulta sobre los temas tratados para un público relativamente amplio, en especial para investigadores, maestros y estudiantes.
Complementary Feeding Practices and Associated Factors Among Nursing Mothers in Southwestern Nigeria
Authors: Samuel Folake Olukemi , Ibidapo Ebunoluwa Grace 
Published: June 2020

Background and Objectives: The period of transition from breastfeeding to other foods and liquids, is a very vulnerable period when malnutrition is likely to start in many infants and young children, if appropriate feeding practices are not employed. This study assessed using composite indices, the appropriateness of complementary feeding practices and associated factors among nursing mothers in Ijebu-Ode, Ogun State.
Methods: This descriptive cross sectional study was conducted in selected primary health facilities in Ijebu-Ode. Multi stage sampling technique was employed to select 283 mother-child pairs. Data was collected using a pre-tested interviewer administered questionnaire which included the World Health Organization Infant and Young Child Feeding Indicators (WHO IYCF) and the Infant and Child Feeding Index (ICFI).
Results: Of the total 283 mother-child pairs studied, 33.6% met minimum meal frequency, 14.5% received minimum dietary diversity (?4 food groups) and 9.2% received minimum acceptable diet when assessed using the WHO IYCF indicators. Overall, appropriate complementary feeding was low (4.2%) and associated (p?0.05) with factors such as antenatal care visits, child welfare clinic attendance and mother’s workplace. On the other hand, the ICFI categorized respondents into low (11.7%), medium (24.7%) and high (63.6%) ICFI scores and were associated (p?0.05) with mother’s education and household size.
Conclusion and Global Health Implications: This study revealed a high prevalence of inappropriate complementary feeding practices. The use of composite indices reflected these practices and their associated factors holistically as they revealed different dimensions of complementary feeding. This may be useful for monitoring, evaluation, research and the required advocacy for complementary feeding.
Key words: • Appropriate complementary feeding • IYCF indicators • Feeding practices • Infant and child feeding index

A New Generalized Model for Predicting the Drag Coefficient and the Settling Velocity of Rigid Spheres in Viscoplastic Fluids
Authors: Okesanya Temitope , Kuru Ergun , Sun Yanxin 
Published: June 2020

Summary
An experimental study was conducted to measure the settling velocity of spherical particles in viscoplastic fluids exhibiting inelastic and elastic behavior. Using a mechanistic model dependent on the balance of the forces acting on the settling particle and detailed statistical analyses of the experimental results, a generalized model for predicting the settling velocity of spherical particles in viscoplastic fluids was developed.
A new modified shear Reynolds number (ReT*) was introduced, which physically quantifies the effects of non-Newtonian-fluid rheological properties on the settling velocity. The newly developed CD/Rep correlation and the modified shear Reynolds number were incorporated into the Wilson et al. (2003) model to develop a generalized model that can be used for predicting the particle-settling velocity in all types of viscoplastic fluids.

Abstract
Introduction: Cardiac injury occurs in 7-22% of patient hospitalized with COVID-19 and an elevation in troponin is associated with a 4.2-fold increase in the risk of mortality. Preliminary data showed ACEi/ARB usage might not increase mortaily in COVID-19 patients. However, it is unknown if cardiac injury in patients with severe COVID-19 can be modulated by ACEi/ARB usage during evolution of the cardiac injury.Methods: In 154 COVID-19 patients with cardiac injury, the effect of ACEi/ARB treatment (17 patients) was compared with 137 patients without ACEi/ARB treatment. Cardiac injury was indicated by cTnI level.Results: In ACEi/ARB treatment group and no ACEi/ARB treatment group, peak cTnI level did not show significant difference (150.5 pg/ml [31.75-1179], vs 207 pg/ml [54.65-989.4], respectively, P = 0.21). Evolution of Cardiac injury (temporal change of cTnI at day 6, 9, 12, 15, 18, 21, 24, 27, 30, and 33) showed no statistical difference. Mortality (ACEi/ARB group vs no ACEi/ARB group; 52.9% vs 69.9%, P = 0.17), atrial arrhythmias (11.7% vs 24.4%, P = 0.36), requirement for invasive ventilatory support (29.4% vs 48.2%, P = 0.14) also showed no significant difference in two groups.Conclusions: ACEi/ARB usage during the COVID-19 was not associated with exacerbation of cardiac injury. These data should be interpreted as essentially hypothesis-generating due to small sample size.Clinical Trial Registration: This retrospective study was registered in Chinese clinical trial registry (ChiCTR 2000031301).

Published: June 2020

Abstract
Background: The Ilizarov technique has been used to treat equinocavovarus foot deformity and has shown good results. However, these results were mostly observed in pediatric patients, and few reports involving only adult case series exist. The aim of this study was to evaluate the outcome of the Ilizarov technique combined with additional procedures for equinocavovarus deformities in adults. Methods: Total 28 adult patients (33 feet) who underwent equinocavovarus foot deformities correction using the Ilizarov technique combined with additional procedures between February 2013 and December 2017 were included. Clinical outcomes were assessed preoperatively and at final follow-up using the Visual Analog Scale (VAS), the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hind foot score, the Foot Ankle Ability Measure (FAAM) score, and the Short Form-36 (SF-36) questionnaire. The radiographic outcomes were measured using weight-bearing ankle and foot radiographs taken preoperatively and at the last follow-up visit.Results: The mean VAS, AOFAS ankle-hind foot scores, FAAM scores were significantly improved (P < 0.0001 for each) at a mean follow-up of 37.30 ±10.94 months. SF-36 scores increased postoperatively in terms of physical function, role-physical, body pain, general health, vitality, social function, role-emotional, mental health, and health transition (P < 0.0001 for each). Early complications were found in 19 feet (57.6%) and late complications were found in 7 feet (21.2%). Radiographs showed that the tibio-talar angle (p < 0.0001), tibial-sole angle (p < 0.0001), talus-first metatarsal angle (p = 0.0004), talo-calcaneal angle (p = 0.0002), and hindfoot alignment view angle (p < 0.0001) were significantly improved. Twenty-seven (97%) patients were satisfied with their outcomes and reported that they would undergo the same procedure if they had the same preoperative deformities.Conclusion: The combination of the Ilizarov technique and additional procedures provides an effective and reliable means of correcting equinocavovarus foot deformity, yielding high levels of patient satisfaction and a low incidence of recurrence. Studies with more cases are needed to assess the results because there are many different etiological mechanisms.

Published: June 2020

Abstract
Background: The need of bioethanol is being increased nowadays; hence the production of bioethanol must be increased using cheaper and eco-friendly raw materials. Based on these criteria, different leaves wastes are considered as cheaper and eco-friendly. In the present study selected tree leaves wastes such as Rain tree, Jackfruit tree, Mango tree and Singapore cherry tree leaves waste were used as raw materials to produce bioethanol by using Saccharomyces cerevisiae (yeast). The operating conditions are pH 6.5, temperature 27±2°C, speed 80rpm, fermentation period 10 days. Also an attempt has been made to find out the suitability of extracted bioethanol as a fuel in CI engine. Results: Experimental work on performance and emission characteristics of ethanol blended diesel fuel was conducted on single cylinder four stroke CI engines at operating pressure 210 bar. The results obtained from this work shows that the higher rate of ethanol can be produced through fermentation of wet Jackfruit tree leaves, which gives good percentage of ethanol as compared to other tree leaves wastes. Conclusions: The conversion of waste into fuel, which forms an attractive solution towards both waste management and Biofuels generation.This study concludes that the Jackfruit tree leaves contain rich fermentable sugar can be converted into useful products like bioethanol that can serve as an alternative energy source.
Revisiting Samuelson's Models, Linear and Nonlinear, Stability Conditions and Oscillating Dynamics
Authors: TRAMONTANA Fabio , Gardini Laura 
Published: June 2020

Abstract
In this work we reconsider the dynamics of a few versions of the classical Samuelson's multiplier- accelerator model for national economy. First we recall that the classical one with constant governmental expenditure, represented by a linear second-order difference equation, is able to generate oscillations con- verging to the equilibrium for a wide range of values of the parameters, and give its analytic solution for all the possible cases. A delayed version proposed in the recent literature, represented by a linear third-order di¤erence equation, is also considered. We show that also this model is able to produce converging oscilla- tions, and give a complete analysis of the stability region of the equilibrium. A new simple nonlinear model is proposed, showing that it keeps oscillatory behavior, although coupled with other dynamics related to global effects. Our analysis confirms that the seminal work of Samuelson and simple modifications of it, may give powerful tools in the study of the business cycles.

Published: June 2020

Abstract
Background Coronary microvascular dysfunction (CMD) is highly prevalent in women with no obstructive coronary artery disease and possibly related to myocardial fibrosis caused by excessive extracellular matrix (ECM) remodeling. ECM turnover can be measured in blood indicating fibrotic activity. We hypothesized that women with DM, angina and no obstructive coronary artery disease have increased ECM turnover and that this is associated with CMD.Methods We included 344 women with angina pectoris and no obstructive coronary artery disease (187 with DM, predominantly type II) and 76 asymptomatic women without DM as controls. Biomarkers reflecting formation of type IV and VI collagen (PRO-C4 and PRO-C6) and degradation of type IV, V and VI collagen (C4M, C5M, C6M), mimecan (MIM) and titin (TIM) were measured in all participants. CMD was defined as coronary flow velocity reserve (CFVR) <2.0 assessed by transthoracic Doppler echocardiography.Results Median age was 64.2 (IQR 57.0-70.0), slightly higher in symptomatic women with DM. Median CFVR was 2.21 (1.89-2.55) in symptomatic women with DM, 2.35 (1.96-2.77) in symptomatic women without DM and 2.63 (2.19-2.95) in controls (age-adjusted p for trend<0.001). With exception of CM5, women with DM had significantly higher levels of all ECM biomarkers than women without DM (age-adjusted p<0.01), whereas biomarkers did not differ between symptomatic women without DM and controls. High ECM biomarker levels were associated with HbA1c, high BMI, low HDL and high triglycerides (p=0.003-0.0001). There was no correlation between ECM biomarkers and CFVR.Conclusion Women with angina pectoris and DM had increased levels of myocardial fibrosis biomarkers compared with women without DM. There was no association between CMD and biomarkers of myocardial fibrosis.
Novel analytical approach for diabetes education based on screening outcomes from Japanese physical examination
Authors: Kumakura Atsushi , Shikuma Junpei , Kan Kenshi , Ito Mariko , Kakizaki Yusuke , Miwa Takashi , Odawara Masato 
Published: June 2020

Abstract
Background: We examined the time-course changes in four variables, namely, fasting plasma glucose (FPG) level, fasting insulin level (FIL), homeostasis model assessment beta (HOMA-b) score, and homeostasis model assessment-insulin resistance (HOMA-IR) score. The variables were examined before and after the onset of diabetes mellitus (DM).Methods: In total, 1,333 Japanese men underwent four annual screenings for diabetes from April 2006 to March 2010. DM was defined as an FPG level ³ 126 mg/dL or glycated hemoglobin level ³ 6.5%. The variables were examined in healthy men and those with DM in the body mass index [BMI] ³ 25 and < 25 kg/m2 groups. The projected FPG level and FIL were assessed based on the simulated HOMA-b and HOMA-IR scores, which is considered a novel analytical approach.Results: In total, 99 (7.4%) men developed DM at any point of the screening periods. The HOMA-b values of the BMI ³ 25 kg/m2 group were 117.6% ± 72.9%, 60.4% ± 29.8%, and 43.1% ± 28.1% at baseline, onset, and 4 years after the onset, respectively. Thus, the decrease in the values was steep. Meanwhile, the HOMA-IR values of the BMI < 25 kg/m2 group were 1.7 ± 0.8 and 2.2 ± 1.2 at 1 year before onset and at onset. Hence, there was an important but slight increase in the values. This result indicates that patients presented with reduced insulin secretion and elevated IR during the onset of diabetes. The values of the four variables remained within normal ranges in healthy men.Conclusions: The novel analytical approach has clinical relevance as it provides a visual material for diabetes education, which is useful in providing caution against the risk of developing DM.
Effect of Y/Mg Ion Ratio and Phase Assemble on Ionic Conductivity of ZrO2 Solid Electrolyte Ceramics
Authors: Hoo Y.G. , Xiao Jianzhong , Xia Feng 
Published: June 2020

Abstract
The phase composition design principle is introduced to obtain a balanced properties of ionic conductivity and thermo-tolerant for zirconia solid electrolyte used in solid oxide fuel cells (SOFCs). The zirconia ceramic solid electrolytes were fabricated by two-step sintering. With increasing Y/Mg ionic ratio from 1.78:1 to 1.88:1, the content of monoclinic phase was not fluctuated widely. The ionic conductivity, including the total electrical resistance; grain electrical resistance and grain boundary electrical resistance at 1223K, was gradually declining with increasing of Y/Mg ionic ratio. Furthermore, the enrichment of Mg ion in grain boundary acts as a disincentive to grain boundary ionic conductivity. In addition, the maximum ionic conductivity at high temperature in this study reaches to 0.143 Scm-1 with increase of the Y/Mg ion ratio.
