Tribo-dynamic analysis of hypoid gears in automotive differentials

Torsional vibrations in differentials of Rear Wheel Drive vehicles are of major importance for the automotive industry. Hypoid transmissions, forming the motion transfer mechanism from the driveshaft to the wheels, suffer from severe vibration issues. The latter are attributed to improper mesh between the mating gear flanks due to misalignments, variation of contact load and shifting of the effective mesh position. For certain operating conditions, the gear pair exhibits high amplitude motions accompanied with separation of the mating surfaces. Ultimately, single or even double-sided vibro-impact phenomena evolve, which have been related to noise generation. This thesis attempts to address these issues by effectively analysing the dynamic behaviour of a hypoid gear pair under torsional motion. The case study considered is focused on a commercial light truck. The major difference of the employed mathematical model to prior formulations is the usage of an alternative expression for the dynamic transmission error so that the variation of contact radii and transmission error can be accounted for. This approach combined to a correlation of the resistive torque in terms of the angular velocity of the differential enables the achievement of steady state, stable periodic solutions. The dynamic complexity of systems with gears necessitates the identification of the various response regimes. A solution continuation method (software AUTO) is employed to determine the stable/unstable branches over the operating range of the differential. The ensuing parametric studies convey the importance of the main system parameters on the dynamic behaviour of the transmission yielding crucial design guidelines. A tribo-dynamic investigation aims at expanding the dynamic model from pure dry conditions to a more integrated elastohydrodynamic (EHL) approach. Analytical and extrapolated solutions are applied for the derivation of the film thickness magnitude based on the kinematic and loading characteristics of the dynamic model. The temperature rise is governed mainly by conduction due to the thin lubricant films. The generated friction is also computed as a function of the viscous shear and asperity interactions. The effective lubricant viscosity is greatly affected by the pressure increase due to the resonant behaviour of the contact load. The final part of this work is involved with a feasibility study concerning the application of Nonlinear Energy Sinks (NES) as vibration absorbers, exploiting their ability for broadband frequency interaction. Response regimes associated with effective energy absorption are identified and encouraging results are obtained, showing the potential of the method.
Sodium and potassium ion rich ferroelectric solid electrolytes for traditional and electrode-less structural batteries

The transition to a sustainable society is vital and requires electrification. Sodium and potassium ion-based electrolytes will likely play an important role in energy storage as these elements are very abundant. The latter cations and chloride are especially interesting since life on the planet is somehow based on biological transfers of these ions through cell membranes. K+ is the key charge carrier in plants. Here, we characterize electrochemically, electrostatically, and structurally novel electrolytes, K3ClO and K2.99Ba0. 005ClO, and compare their performance with Na3ClO and Na2.99Ba0. 005ClO in symmetric and asymmetric structural electrode-less cells, such as K/K2.99Ba0. 005ClO in a cellulose membrane/K, Na/Na2.99Ba0. 005ClO in a cellulose membrane/Na, Al/K2.99Ba0. 005ClO composite/Cu, and Al/Na2.99Ba0. 005ClO composite/Cu, at temperatures that range from −45 to 65 °C. An ab initio molecular dynamics structural study followed by band structure determination using density functional theory and hybrid simulations allowed us to compare the amorphous character of the structures, bandgap, and electron localization function for both K3ClO at 25 °C and Na3ClO at 37 °C, temperatures at which preliminary studies indicate that these compounds are already amorphous. As in Na+-based electrolytes, the ferroelectric character of the K+-based electrolytes is well recognizable, especially at −45 °C, where the relative real permittivity achieves 1013 in K/K2.99Ba0. 005ClO in cellulose membrane/K symmetric cells for an ionic conductivity of ∼120 mS/cm. As in Na+-based electrodes-less structural battery cells, self-charge and self-cycling phenomena are also demonstrated reinforcing the ferroelectric nature of the A3ClO (A = Li, Na, and K) family of electrolytes. These studies may contribute to understanding the K+ and Na+ transfer behavior in energy harvesting and storage as well as the biologic world.
Social Responsibility Accounting, Disclosure and Real Practice: Evidence from Jordan

This study aims to present a true image of social responsibility accounting (SRA) in Jordanian companies listed on the Amman Stock Exchange (ASE). A survey questionnaire was employed to check the level of SRA practice, and a checklist was used to discover the level of SRA disclosure which was collected from the annual reports of the firms listed on the ASE. The questionnaires and annual reports were employed to collect information from 104 companies in the financial, services, and industrial sectors for this study. SPSS was used to for data analysis and the results showed that the level of SRA practice in listed companies on the ASE is good, while the level of SRA disclosure is very low. The latter could be related to many reasons, including lack of awareness of Jordanians companies' managers in the culture of SRA and related issues due to the novelty of SRA disclosure in Jordan and developing countries. In addition, companies mostly focus on product quality when they practice SRA.
The Role Of Intellectual Capital In Intervening Financial Behavior and Financial Literacy on Financial Inclusion

Education is very important to reduce the percentage rate of the number of unbanked people. This research was conducted by focusing and convincing many people about the importance of financial behavior in reducing financial inclusion in developing countries, such as Indonesia. The number of samples are use 500 respondents. The analysis method uses the Partial Least Square (PLS) method and structural equation model (SEM) based on variance. This research found that financial behavior and financial literacy have a positive and significant influence on financial inclusion. Intellectual capital also detected capable of intervening a strong relationship between financial behavior and financial literacy on financial inclusion. This discovery contributing is very important for stakeholders who want to improve financial access for all unbanked people in developing countries through the concept of financial behavior. There needs to cooperation from various elements, such as the central bank of each country, academics, practitioners, digital financial institutions, and social elements of the community to foster good financial behavior with each other, so that financial inclusion can be resolved in a directed manner.
Failing to Plan Is Planning to Fail: Toward an Expanded Notion of Democratically Planned Postcapitalism

With the advent of digitalization, the more techno-optimist among critics of capitalism have articulated new calls for post-work and post-scarcity economics made possible by new advances in information and communication technology. Quite recently, some of this debate shifted for calls for digital-democratic planning to replace market-based allocation. This article will trace the lineages of this shift and present these new calls for digitally enabled and democratic planning. I will then argue that much of the discussion focuses on capitalism’s laws of economic motion, while rendering less visible capitalism’s social, political, and ecological ‘conditions of possibility’. To remedy this shortcoming I will ask how these fit into the recent debate and suggest avenues to extend the discussion of democratic planning in that way. Concretely, I will discuss features of a postcapitalist mode of reproduction that abolishes capital’s subordination of non-waged and waged care work. The following part will focus on both planning’s need to calculate ecological externalities and consequently determine sustainable and egalitarian paths for social and technological development on a world scale. The last section will elaborate on the ‘democratic’ in ‘democratic planning’ in terms of planning’s decision-making, multi-scalar politics, and politics of cultural recognition.
Z08: low-speed aero-acoustic experimental characterization of open rotor installation on aircraft

Airbus carried out an extensive test campaign named Z08, in cooperation with Snecma and Rolls-Royce, between spring 2012 and early 2013 to characterize the low-speed aeroacoustics behaviour of an open rotor for several levels of aircraft installation. The test campaign was done in the DNW-LLF open jet wind tunnel. The test setups included an isolated engine configuration, a configuration with the engine mounted behind a supporting pylon and a representative aircraft with two rear-mounted engines in a Pusher configuration. The pylons were equipped with a blowing system designed to reduce the blade passing frequency tones. In addition to AI-PX7 generic blades designed by Airbus, Snecma and Rolls-Royce provided advanced blade designs. Besides the usual DNW out-of-flow microphones, an in-flow acoustic instrumentation was used to enlarge the polar and azimuthal angular range measured, to have a high spatial resolution of the measured noisefield and to avoid the noise propagation issues through the wind tunnel shear layer. This paper presents a few test results with the AI-PX7 blades regarding open rotor installation effects for the Pusher aircraft. As an example, the test analysis highlights that the open rotor aircraft installation results in additional noise sources on front rotor blade passing frequencies compared to the isolated with pylon configuration. It also shows that the acoustic benefit of pylon blowing is confirmed on the aircraft configuration. Open rotor acoustic installation effects mitigation is indeed not limited to pylon blowing optimisation. The Z08 test campaign confirmed the need to carefully handle open rotor propulsion system installation with the aim of minimising inflow distortions into the propeller disks and consequently decrease its acoustic impact.
Religion and Science in Context of Islam and Korean Christianity

ABSTRACT This article suggests three important conclusions through examining dialogical methods of religion and science as well as religious contexts: Islam and Korean Christianity. Firstly, Ted Peters'hypothetical consonance as well as Zainal Bagir's philosophical and theological appreciation of science could be the appropriate models for a dialogue between science and non-Christian religions. Secondly, colonial experiences of Islam should be considered when non-Western religions engage with science. Finally, a local and distinctive context, such as Korean Christianity, can supplement what the Western view of Christianity and the postcolonial view of religion might omit when engaging in dialogue between religion and science.
Prevalence of Hypertensive Diseases and Associated Risk Factors above 30 Years Adult People Admitted in Morogoro Regional Refferal Hospital 2021, Tanzania

Hypertension is the commonest cardiovascular disorder due to its role in the causation of coronary heart disease, stroke and other vascular complications. In Tanzania, hypertension is one of major risk factors for cardiovascular mortality and it’s attributed for 10% of all deaths. Increasing prevalence in hypertensions expected due to economic transition, increased population growth, aging behavioural risk factors, such as: unhealthy diet and excessive alcohol consumption. Awareness of hypertension and risk factors for hypertension is less among rural. Retrospective Cross Sectional study was conducted over a period of 2 months, June to July 2021 among adults. Among 384 study subjects, 168 were males and 216 were females. The prevalence of hypertension was observed to be 45%. Prevalence increased as the age increased. The prevalence of hypertension was high among obese, these who had history of diabetes Mellitus. Among the study subjects 24.1% (112) were aware of their hypertensive status of these 18.4% that were on regular treatment. The prevalence of hypertension was 45%. Various factors like increase in age, obesity and history of diabetes are implicated in the occurrence of hypertension.
A longitudinal study of foreign language enjoyment and boredom: A latent growth curve modeling

The present research aimed to explore the dynamic growth of two emotional constructs: foreign language enjoyment (FLE) and foreign language learning boredom (FLLB) among L2 learners. To do so, we used a method that would capture the inherent dynamicity of L2 learners’ enjoyment and boredom during an EFL course. To this aim, a bivariate latent growth curve model (LGCM) was employed to examine the covariance between 412 EFL learners’ initial and growth levels of FLE and FLLB on four measurement occasions at two-week intervals. To collect the data, the original FLE scale and the newly developed FLLB scale were used. The model including the covariance between intercepts and slopes of FLE and FLLB was tested in Mplus 7. The analysis of the data revealed that the covariance between the intercept and slope of the FLE and FLLB was statistically significant and negative. This attests to the existence of a parallel process (co-variance) of FLE and FLLB, which indicates that an increase in the level of FLE among the participating L2 learners was strongly associated with a decrease in the level of FLLB during the whole course. The findings and implications are discussed in light of the existing literature.
Active growth of the Bengal Fan during sea-level rise and highstand

New stratigraphic and high-resolution seismic data from the Bengal Fan indicate that the world9s largest fan shows active growth during the most recent sea-level rise and the recent highstand. This unique phenomenon contradicts common sequence-stratigraphic models, and the sediment preserved provides new insight into the sedimentological response of a fan system to sea-level rise, climatic terminations, and monsoon intensity during the past climatic cycle. We present a detailed dated sequence of turbidite sedimentation based on a core transect perpendicular to the active channel-levee system in the upper mid-fan area. Between the two major terminations 1a (12 800 14 C yr B.P.) and 1b (9700 14 C yr B.P.), and especially at the end of the Younger Dryas, a 13-km-wide channel built up levees 50 m high. With decreasing sediment supply, continued sea-level rise, and increasing monsoon intensity during the early Holocene, turbidity currents were confined to the channel and gradually filled it. The canyon “Swatch of No Ground,” a shelf depocenter that serves as the source for frequent turbidity currents, and the channel-levee system provide the unique opportunity for studying an active highstand system. Many fans showed this behavior only during lowered sea-level.
Evaluation of Simulated Cloud Diurnal Variation in CMIP6 Climate Models

Cloud diurnal variation (CDV) affects cloud radiative effects significantly as clouds reflect shortwave radiation only during the daytime but trap outgoing longwave radiation in both daytime and nighttime. Meanwhile, CDV also rectifies atmospheric variations of longer time scales via interactions with other physical and dynamic processes. These make CDV a valuable aspect for diagnosing climate model performance. Here, we evaluate the accuracy of simulated CDV in state‐of‐the‐art global climate models (GCMs) by comparing CDV in the historical simulation of 32 GCMs from 20 institutes participating the Coupled Model Intercomparison Project Phase 6 (CMIP6) with observations from the International Satellite and Cloud Climatology Project‐H product. While good agreement is found over the oceans, significant biases exist over land (notably deserts and plateaus), where the models simulate excessive nighttime clouds and insufficient daytime clouds and miss the observed peak of cloud fraction in the early afternoon. These biases persist throughout the year. It is illustrated that correcting the CDV biases tends to reduce the known model biases of smaller shortwave cloud radiative effect over the midlatitude Africa‐Europe‐Asia continent, South America, and vast ocean areas. Inter‐model comparisons show that the CDV biases vary significantly among models from different institutes and present similar characteristics among models from the same institutes, and suggests that the biases are more likely to be attributed to deficiencies in cloud‐related physical parameterizations rather than the model treatment of resolution, ocean, and chemistry. The improvement of CMIP6 models against their CMIP5 counterparts in simulating CDV is also discussed.
Resilience to Cheating among Students at Felix Houphouët-Boigny University of Cocody (Abidjan, Côte d’Ivoire)

This study aims to understand the phenomenon of resilience to cheating among students at Félix Houphouët-Boigny University, where the research took place. The research was based on 211 participants from different training and research units. The level of study varies from Bachelor to Master. Data were collected using a survey questionnaire. The advantage of this instrument is that it is the most suitable way to collect large amounts of data. The results obtained reveal that exogenous factors (level of study, preservation of the image of the family and valuation of learners’ efforts at work by teachers) and endogenous (personal effort and commitment and development of capacities to be autonomous, to not be dependent on others) best explain the resilience to cheating among UFHB students.
Machine Learning for Pan Evaporation Modeling in Different Agroclimatic Zones of the Slovak Republic (Macro-Regions)

Global climate change is likely to influence evapotranspiration (ET); as a result, many ET calculation methods may not give accurate results under different climatic conditions. The main objective of this study is to verify the suitability of machine learning (ML) models as calculation methods for pan evaporation modeling on the macro-regional scale. The most significant PE changes in the different agroclimatic zones of the Slovak Republic were compared, and their considerable impacts were analyzed. On the basis of the agroclimatic zones, 35 meteorological stations distributed across Slovakia were classified into six macro-regions. For each of the meteorological stations, 11 variables were applied during the vegetation period in the years from 2010 to 2020 with a daily time step. The performance of eight different ML models—the neural network (NN) model, the autoneural network (AN) model, the decision tree (DT) model, the Dmine regression (DR) model, the DM neural network (DM NN) model, the gradient boosting (GB) model, the least angle regression (LARS) model, and the ensemble model (EM)—was employed to predict PE. It was found that the different models had diverse prediction accuracies in various geographical locations. In this study, the results of the values predicted by the individual models are compared.
Influence of Information Culture on Job Satisfaction of University Registry Personnel in South-West, Nigeria

This study aims to investigate the influence of information culture on job satisfaction. The study adopted survey research design. The population consisted of 2009 registry personnel working in federal, state and private universities in South-West, Nigeria. Stratified random sampling technique was used to select 715 personnel. A validated questionnaire was used for data collection. Response rate was 70%. The data were analysed using descriptive (mean and standard deviation) and inferential statistics (regression). Findings from the study showed that information sharing (β = 0.054; t(497) = 1.227; p > 0.05), information proactiveness (β = -0.006; t(497) = -. 132; p > 0.05) and information control (β = 0.027; t(497) = . 537; p > 0.05) did not significantly influence job satisfaction. The study concluded that information culture contributed to the level of job satisfaction of university registry personnel in South-West, Nigeria in terms of quick access to relevant information to enhance service delivery and openness in information sharing. Consequently, it was recommended that the university management should improve on institutional information culture practice to enhance the job satisfaction of the university registry personnel.
Outcome Comparison of Totally Implantable Venous Access Device Insertions Between Surgeons and Radiologists in Australia

Background The need for chemotherapy treatment is increasing with the growing incidence of cancer worldwide. The insertion of totally implantable venous access devices (TIVADs) is commonly performed by surgeons and radiologists, but the procedures are not without complications. The primary outcome of this review outlines TIVAD insertion success and complication rates between general surgeons and radiologists. The secondary goal of this study is to help identify areas for improvement and consideration when performing TIVAD insertion. Methodology This was a descriptive, three-year, retrospective multicentre study of oncological patients who underwent TIVAD insertion by either general surgeons or radiologists at two peripheral Brisbane hospitals. Results Surgeons performed 61 percutaneous subclavian vein cannulations, 29 ultrasound-guided internal jugular veins, and seven open cephalic veins cut-down TIVAD insertions (n=97). Overall surgical success was 81.4%, with the internal jugular (89.7%) having the highest success rate followed by the open cut-down (85.7) and subclavian approaches (77.0%). The overall surgical complication rate was 16.4%, with five pneumothorax, five port malfunctions, three haemorrhages, two infections, one thrombus, and one mediastinal injury. Each pneumothorax was associated with subclavian cannulation attempts. Two haemorrhages were associated with both open cephalic and subclavian attempts. Radiologists performed 248 ultrasound-guided internal jugular vein TIVAD insertions (n=248) with 247 successful first attempts (99.5%). Within the radiology group, there was an overall complication rate of 15.3% with 22 infections, 14 port malfunctions, one haemorrhage, and 1 mediastinal injury. Conclusion Ultrasound-guided internal jugular vein TIVAD insertion had the highest first attempt success rate in both the surgical and radiology groups.
