Published: October 2023

Experimental methods and numerical analysis were used to investigate the mechanism of high-speed knocking that occurs in small two-stroke engines. The multi-ion probe method was used in the experiments to visualize flame propagation in the cylinder. The flame was detected by 14 ion probes grounded in the end gas region. A histogram was made of the order in which flames were detected. The characteristics of combustion in the cylinder were clarified by comparing warming up and after warming up and by extracting the features of the cycle in which knocking occurred. As a result, regions of fast flame propagation and regions prone to auto-ignition were identified. In the numerical analysis, flow and residual gas distribution in the cylinder, flame propagation and self-ignition were visualized by 3D CFD using 1D CFD calculation results as boundary conditions and initial conditions. Flame propagation calculated by 3D CFD was found to be directional due to in-cylinder flow caused by scavenging flow. The calculated direction of flame spread was matched with the experimentally measured direction. It was also found that the first auto-ignition occurred in the high temperature region where the concentration of residual gas was high. Finally, numerical analysis was performed for the high compression ratio engine specifications. As a result, the mechanism of knocking was clarified as the first auto-ignition caused by the high-temperature residual gas, followed by the pressure wave inducing continuous auto-ignition. The flow formed during the scavenging process and the subsequent compression process determine the directionality of flame propagation and residual gas distribution at top dead center. Thus, the possibility of knocking avoidance by scavenging air shape and combustion chamber shape was suggested.

The regulatory framework of pollutant emissions concerning non-road small internal combustion engines is becoming increasingly challenging. The upcoming scenario threatens to cut out small two-stroke engines because of the fuel short circuit occurring during transfer and exhaust ports overlap, causing the emission of unburned hydrocarbons and reducing engine efficiency. Despite this challenge, small two-stroke engines are unmatched in high power density applications in which weight and autonomy hinder the diffusion of electric technologies. The continuation of small two-stroke engines in the market will thus depend on the capability of mitigating fuel short circuit. From this perspective, some of the Authors found the low-pressure injection technology fulfilling the purpose at engine full load; however, in addition to system complexity and costs, a lack of mixture homogenization was noted at low load. Another solution concerns the adoption of a pocket milled in the piston skirt, connecting an auxiliary air intake to the transfer ducts by means of additional ports. This feature leads to the filling of the transfer ducts with fresh air only, reducing fuel short circuit during scavenging. Due to the fluid dynamic complexity, stratified-scavenging engines are typically investigated via experimental or CFD analyses, leading to high costs and times. In the present paper, a novel 1-D numerical approach for the study and optimization of a 55 cm3 stratified scavenging engine is introduced. The model, developed in the GT-Suite framework and validated through test-bench data, allows the replication of complex phenomena like air stratification. The effects of pocket volume, phasing of ports, as well as length of transfer channels, in terms of air stratification and fuel short circuit, is discussed in detail in order to provide design guidelines for stratified-scavenging engines and to find the best setup for the present test case.

Published: October 2023

Control observer-based estimation methods are getting a very rapid appreciation
due to their better reliability, stability and ease of implementation in already
controller-packed electric vehicles and energy storage systems. As a careful
sensitivity analysis is the one vital tool to enhance the accuracy and
robustness of lithium-ion battery’s states estimation, an experimental
sensitivity analysis is proposed to enhance the accuracy and efficiency of
battery states and parameter estimation of non-linear control observer. This
paper categorically uses INR21700-M50T cells for experimental characteristic
analysis of lithium-ion batteries. The results of this practical work are then
used in the successful design, simulation and validation of an advanced
proportional integral observer. The validated proportional-integral (PI)
observer is then used to carry out the proposed sensitivity analysis, and
deviations resulted in estimation accuracy due to the sensitivity of each
parameter are analyzed, closely examined and dominant/highly sensitive parameter
is identified based on the new estimation error statistics. Finally, the
valuable insights are concluded on the need for improved identification and
simultaneous estimation of dominant parameters in control observers.

Published: October 2023

Invasive Fungal Infections have posed a difficult challenge in the recovery of people infected with COVID-19. COVID-19-associated pulmonary aspergillosis (CAPA) has been described and found in about 30 % of ICU patients worldwide. Here we present an unusual microscopic finding in a case of CAPA in an ICU patient which was helpful in initiating early definite therapy. A 56-year-old gentleman presented with complaints of fever and shortness of breath and subsequently tested positive for COVID. Post admission, his respiratory distress worsened and his condition deteriorated. A provisional diagnosis of COVID pneumonia with acute respiratory distress syndrome (ARDS) was established based on chest radiographic finding of left lower lobe consolidation, increased pulmonary infiltrates in bilateral lung fields with evidence of pleural effusion. Pleural Aspirate obtained via ultrasound guided thoracocentesis revealed branched hyaline septate hyphae along with structures which were composed of elongated vesicle with one layer of phialides covering two-thirds of the vesicle and bearing globose conidia on KOH direct mount. Aspergillus flavus grew on culture, which was later confirmed by MALDI TOF VITEK MS. Patient was diagnosed with Proven Invasive Pulmonary Aspergillosis with COVID-19 and voriconazole was started. Patient successfully recovered and was discharged. Identifying the Aspergillus species directly on the basis of KOH Mount, helped in decreasing the turnaround time, in early initiation of definite therapy and possibly contributed to the favorable outcome. CAPA is a potentially life-threatening complication in patients with severe COVID-19, thus a timely diagnosis and treatment becomes crucial in the management. Keywords: CAPA, COVID-19, Aspergillus

Comparison Study between Different Methods Used in Estimation of Initial Oil in Place for Asmari Reservoir, Southeastern Iraqi Oilfield
Authors: Abdulmajeed Rwaida
Published: October 2023

In the oil industry, estimating the presence of oil reserves is a key issue during the reservoir exploration, evaluation, and development stages and should be investigated because of the risks and inaccuracies that are considered inherent issues. Moreover, true and distinct hydrocarbon content can only be discerned upon field production or depletion. The challenge of estimating reserves is therefore a function of time and available data. In this study, Different Known modules with varying levels of analytical accuracy were utilized to establish the Initial Oil InPlace (STOIIP) of the Asmari reservoir in Fauqi Oilfield through analysis of production history from one well. The accuracy of the results obtained was examined and showed an acceptable level of reliability. Results from various models indicate that the most reliable estimate of OOIP is approximately 1.01MMMbbl for the Asmari reservoir using a multi-column model. Furthermore, by performing different analytical and numerical calculations on the Fauqi well production history, the uncertainty in the reservoir calculations of STOIIP can be reduced.

Design of dual COX-2/5-LOX inhibitors can be considered an adequate approach in the development of new anti-inflammatory drugs with less pronounced side effects. The aim of the present research was to examine the binding potential of the seven newly designed thiourea derivatives of naproxen towards COX-2 and 5-LOX. The binding analysis of ligand conformations was performed by OEDocking 3.2.0.2 software. The binding potential assessment revealed that thiourea derivatives of naproxen exhibited a comparable binding affinity as naproxen towards COX-2. The highest number of key binding interactions with 5-LOX was formed by compound 5, whereas compound 6 established the most stable complex (-9.29 kcal/mol). According to the obtained results, derivatives 5 and 6 can be considered as dual COX-2/5-LOX inhibitors with potential anti-inflammatory activity. However, none of the investigated compounds were able to form three hydrogen bonds with the binding site of COX-2, as well as three key hydrogen bonds with the active site of 5-LOX.

The starting point of the paper is the idea that modern challenges and tendencies within institutional preschool education might be responded to by considering the implicit pedagogy domains, which include the institutional context, the educator-child interaction, interaction among children, and (self-)reflection during the process of professional development and educator’s autonomy. An overview of the conducted action research aimed at encouraging friendship among preschoolers in institutional context is provided. Initial values of the research are the following components of children’s friendship: empathy, compassion, self-confidence, fairness, communication, ability to solve conflicts, group harmonization, sharing, and cooperation. In a broad sense, the research problem is triggered by the issues in education which bring about social changes in the permissive consumer society. The subject of the research is the improvement of relationships among children and their peer status in an educational group. The study lasted for six months and covered eight educational groups and sixteen educators. The intention was to create a stimulating environment for friendship development and help the educators reflect on their practices by covering 19 activities referring to social and emotional aspects of children’s development and education. The findings of the continuous monitoring of the action research suggest that children had high scores in friendship tests; the unsociable children who had a negative peer status in socio-metric studies managed to increase their peer status; and, finally, the group cohesion improved and professional competencies of the educators enhanced.

The paper presents a comparative analysis of integrated learning in preschool institutions in Sweden and Serbia. In addition to supporting cognitive development, an integrated approach to learning also supports the full development of preschool children. In Serbia, integrated learning started in 2018 with the adoption of the Rulebook on the new foundations of the preschool education program. The results of integrated learning in Serbia have not indicated the expected effects so far, since it was started systemically and without creating optimal conditions for its implementation, with still insufficiently trained educators. Integrated learning in Sweden has been in use since 1998. It was revised in 2019 with the adoption of the Preschool Curriculum - LPFÖ 18. Based on the results of the comparative analysis, conclusions and a proposal for the improvement of integrated learning in preschool education in Serbia are given.

Walking is the most elementary and simple form of movement and is the first symbol of communication characteristic of an individual. Walking, as a natural form of movement, is an essential part of the process by which the child develops his movement and functional abilities. To walk, the child needs coordination of the movements of arms and legs, balance and rhythm, good strength of all muscle groups, orientation in space, a good sense of body control and additional functional skills. For the development of a child’s walking, it is very important to provide him with a stimulating environment and give him the opportunity to take his first steps independently. By analysing the results of studies, the gradual development of walking in terms of the direction of movement in space was confirmed. Cross-walking up and down stairs occurs in the second age group, while most children in the first age group crosswalk only on the surface of the apartment. Given the age of the children, the transition to independent walking was characterized by prolonged interaction with the mother and more complex interactions, including directing the mother’s attention to specific objects. The results suggest a developmental pathway that links social interactions with milestones in motor development. By encouraging physical activities, we enable the child to have a well-developed physique, which is very important for the development of walking.

Women's empowerment is one of the major topics of debate today. On the one side, we pledge to reduce gender inequality, talk about their fundamental rights, and make efforts to make them empowered and on the other side, several cases of their exploitation and extortion come across in our family and society. The male dominant society and mindset are assumed to be the most notorious cause of gender inequality. In this paper, we try to analyse women's empowerment in the absence of male members.

One indicator that shows how effective and efficient a company is in achieving its goals is its financial performance. Maintaining and improving financial performance is mandatory for a company to continue to exist and attract investors. This financial information functions as a means of information, a tool for management accountability to business owners, a representation of company success indicators, and consideration for decision making. Tobin's Q is an indicator that can be used to measure a company's financial performance from an investment perspective. The aim of this research is to find out the conditions and determinant factors in analyzing financial performance in consumer cyclical companies for the 2015-2022 period. The research method uses dynamic panel data regression with the Arellano-Bond Generalized Method of Moment (GMM) approach on 24 consumer cyclical sector companies from 2015 to 2022 listed on the BEI. The research results show that partially the company value in the previous period (Tobin’s Q(-1)) has a significant positive effect and can be backward looking towards achieving high and sustainable company value (Tobin’s Q) in the next period. Profitability (ROA) has a significant positive effect on company value (Tobin’s Q). This shows the company's prospects for sustainability in the future.

The purpose of this study was to explore measures that could best serve as prerequisites for the efficient and effective implementation of the new curriculum in Namibian schools. The study used a qualitative research methodology, which employed a case study design. Semi structured interview and open-ended questionnaire were used to obtain data from the participants and respondents. The sample was made up of teachers and schools principals who were purposively sampled because of their typicality to the subject of research. The collected data was analysed using thematic analysis method. Key findings reveal that efficient and effective implementation of the new curriculum could best be achieved through the provision of adequate resources to schools before the curriculum was rolled out. Adequate resources were regarded as a measure of school readiness in implementing the new curriculum. Support programmes were also essential to equip teachers with necessary skills for them to meet the expectations of the new curriculum and enable them to discharge their duties effectively. The study also revealed that any implementation of the new curriculum should be informed by promising evidence of piloting, suggesting that a pilot study was needed to render the implementation of the curriculum effective. The study concluded that the implementation of the new curriculum in slowly gaining momentum due to various critical measures that needed to be considered before it was implemented. Thus, it is recommended that the measures as discussed in this article could still be considered and applied for improved operational efficiency and effectiveness of the implementation of the new curriculum in Namibian schools.
Essays on multidimensional poverty and gender in Brazil
Authors:   , Batista Andrezza Luiza
Published: October 2023

This thesis is dedicated to studying Brazil's multidimensional poverty with a gender focus. Specifically, we consider poverty a phenomenon that affects people’s live’s in several aspects other than income, such as education, employment, and living conditions. Also, we consider that poverty is driven differently by men and women due to social, economic, and cultural gender differences. Hence, the first essay aimed to analyze the multidimensional poverty in Brazil with a breakdown of gender, race, and regional disparities. To do so, a Multidimensional Poverty Index was constructed with eleven indicators (years of schooling, literacy, employment, income, electricity, sanitation, water, garbage disposal, cooking fuel, assets, and overcrowding) within four dimensions (education, employment, income, and living standards). We used data from the National Household Sample Survey (PNAD) from 2004 to 2015. The results found in this chapter indicated that women have higher deprivation than men. They are the majority of people experiencing poverty and suffer a more intense form of poverty than men. Black women and the ones living in rural areas are in a situation even worse. We also found that employment and income are the dimensions that drive multidimensional poverty in Brazil and that women in Brazil have difficulty transforming education into income. Additionally, results showed that women’s poverty has been reducing slower than men’s. The second essay analyzed whether migration and nonagricultural jobs can be seen as pathways out of multidimensional poverty for individuals from rural Brazil, breaking it down by gender. The relationship between livelihood strategies and multidimensional poverty was estimated by a two-stage least squares estimation considering extreme climate events in temperature and precipitation as instruments for migration and nonfarm performance since they can be considered endogenous. The data used was also the National Household Sample Survey (PNAD) from 2004 to 2015. We used the deprivation score calculated by the Multidimensional Poverty Index method for the dependent variable. The results of this paper suggest that performing nonagricultural activities can act as pathways out of poverty in rural Brazil, reducing deprivation, but only for men, and that migration is irrelevant in explaining the changes in deprivation. In general, this thesis contributes theoretically and empirically to understanding several facets of poverty in Brazil. Keywords: Multidimensional poverty. Deprivation. Gender.

Introduction: lower limb injuries and low back pain are common injuries in field hockey that have different risk factors. The aim of this study was to characterize youth field hockey players’ physical condition to determine their possible injury risk factors. Methods: youth field hockey players of the Club Deportivo Universidad Católica of Chile were assessed during April and May of the 2022 season. The test used were: Ely’s, Thomas, Ober and AKE for flexibility, Biering Sorensen, Plank Test, Sport Specific Endurance Plank Test, Single Leg Bridge Test, Lunge Test, Hop Test (single, triple and croo-over) and Y Balance Test. Statistical analyses were performed using R Statistical Software (2023.09.0+463; R Core Team 2023). Results: 87 youth field hockey players from the under 14, 16 and 19 were assess (age 15.1 ± 1.5). Poor core and back extensor endurance was found, along with poor hamstring strength and unipodal balance. Significant difference was found between categories in the plank test and sport specific endurance plank test (p<0.001). Conclusion: several impairments were found in chilean youth field hockey players that could pose a risk of injury, however, further research is needed in order to determine if these impairments really are risk factors in this sport and population.

A Common Thread for Adaptive Management Planning of Small-scale Fishermen Needs versus Government Policy in South Papua, Indonesia
Authors: Ivonne Raystika Gretha Kaya  , Sajriawati
Published: October 2023

Indonesian government has established measurable fishing regulations by Government Regulation 11/2023 to protect and sustain fishery resources. This policy is unsuitable for small fishermen's needs and has resulted in mass demonstrations in South Papua. Data were conducted with the fishermen demonstrators (n=100) by participation observation, in-depth and semi-structured interviews. The results showed fishermen refused the regulated fishing regulations for vessels <30 GT as far as 12 miles, simplify the licensing process, increase the fuel quota and repeal mooring requirements only at the Merauke fishing port. Formulating laws and regulations for fisheries management requires a combination of ecological, economic, and sociocultural principles to sustain fisheries systems. Stakeholder involvement must be implemented into every policy design and decision-making stage by integrating fishermen's perspectives in the fishing business. Integrating fishermen's points of view can be a benchmark for the suitability of fishermen needs and sustainability of fisheries resources in each region.
