Common transmission theory and wide application

Gear and belts/chains are the most common solution for modern mechanical devices. The allowable stress and gear ratio are two of the main factors that decide the performance of the ear section for transmission. The allowable stress can be calculated by bending stress and contact stress from design criteria. The performance of the belt solution is decided by the belt/chain material, center distance and the belt length. The allowable strength of the belt/chain solution is strongly related to the materials selected. With the current study of belts and gears, the related factors could be calculated to design the optimum shape and material. Dual clutch transmission (DCT) and continuously variable transmission (CVT) are two widely applied transmissions with gear and belt/chain solutions that are introduced in the research. The advantages of DCT could be the reliability and high transmission efficiency of the gear solution and the space and energy efficiency of belt/chain structure advantages of the CVT. Both DCT and CVT could be applied in different conditions to maximize the specific performance.

Investigation of the presence of the virus in the urine and fecal samples of COVID-19 diagnosed and suspected patients by RT-PCR method: A different perspective on fecal-oral transmission theory

With the sudden COVID-19 outbreak in 2019 which has taken over the whole world, drastic changes have taken place on a global level from the understanding of hygiene to living conditions. Although the disease is often detected using respiratory tract samples with PCR tests, many publications state that the virus can also be traced in various body wastes. In our study, we aimed to determine the frequency of the virus in 50 urine and 50 stool samples and to reveal the relationship between the patients' stool PCR results according to Computed tomography (CT), biochemical tests, and the positivity of respiratory PCR test with microbiological samples. The presence of SARS-CoV2 RNA in the urine and stool samples of the patients was detected by qRT-PCR methods. Shapiro-Wilk normality test was applied to the CT, respiratory tract PCR and biochemistry results of the patients. As shown by the results, while none of the 50 patients had positive urine samples, we detected COVID-19 viral shedding in the stool specimens of 15 patients. Respiratory PCR test was negative in 4 of the stool-positive patients. No significant correlation was found between CT results and the biochemistry results of 15 patients with positive stools. In our study, the rate of viral shedding in feces was found to be 30%, which we think may be a finding to demonstrate how the pandemic rapidly progresses in cities due to the viability of the virus outside the body.

Analysis of Narcotics Circulation in Riau Province; inherited and studied in the View of Criminology Integrative Theory

<p class="TableParagraph"><em>The rise of narcotics smuggling in Indonesia is a complex issue that requires a comprehensive explanation. The use of integration theory, specifically the integration of Cultural Transmission and Differential Association, can provide a better understanding of the phenomenon of narcotics crime in urban areas. Cultural Transmission theory suggests that individuals learn their values, beliefs, and behaviors through the process of socialization within their culture. This theory highlights the role of family, peer groups, and the media in shaping an individual's attitudes and behaviors towards drugs. The theory argues that individuals who are exposed to drug use at an early age are more likely to engage in drug use themselves. On the other hand, Differential Association theory suggests that individuals learn deviant behaviors from their associations with others. The theory posits that individuals who associate with those who engage in deviant behavior, such as drug use, are more likely to adopt those behaviors themselves. By integrating these two theories, we can better understand the complex phenomenon of narcotics crime in Indonesia. The use of rat ports as entry points for illegal drugs can be explained by the influence of cultural transmission, where individuals are exposed to drug use through their socialization process. Furthermore, the use of these rat ports can also be explained by differential association, where individuals who associate with drug smugglers are more likely to engage in the smuggling of narcotics themselves. Overall, the integration of Cultural Transmission and Differential Association theory provides a more nuanced understanding of the complex phenomenon of narcotics crime in Indonesia. By considering the various factors that contribute to the rise of narcotics smuggling, we can develop more effective strategies to combat this issue.</em><em></em></p>

Slowdown of group velocity of light in dual 1480 nm hybrid pump cascade structure of Er3+-doped optical fiber at room temperature

In this paper, a general theory of slow light transmission in dual 1480nm hybrid pump cascade structure of Er3+-doped optical fiber at room temperature is presented. Our objective is to compare the dual 1480nm hybrid pump cascade structure with the 1480nm and 980nm hybrid pump cascade structure in relative modulation attenuation, time delay, fractional delay, group velocity, refractive index, and signal optical loss. Through theoretical calculation, the maximum time delay is increased by 1.111 times and 1.162 times, and the maximum fractional delay is increased by 1.091 times and 1.132 times when the pump power ratio M=0.5 and 0.75. The loss coefficient is reduced to 0.1 when M=1. The results show that compared with the previous research methods, the dual 1480nm hybrid pump cascade structure can obtain larger time delay, fractional delay and smaller loss, which may have important applications for the optimization of optical communication systems.

Sound Insulation of Single-Layer Glazing, Single- and Double-Glazed Windows

The analysis of known analytical solutions to the problem of calculating transmission the sound insulation of one- two- and three-layer glazing in comparison with the results of laboratory measurements is presented. The wave theory of sound transmission through single-layer and multi-layer enclosing structures with air gaps is used. Based on calculations of sound insulation of single-layer glazing, it is shown that the theory underlying the methodology of GOST R EN 12354-1–2012 “Acoustics of buildings. Methods for calculating the acoustic characteristics of buildings based on the characteristics of their elements. Part 1. Sound insulation of air noise between rooms”, most adequately takes into account the processes of non-resonant and resonant sound transmission. Its use in the formulation of models of sound transmission through double and triple glazing, taking into account internal losses and the influence of resonant processes, made it possible to obtain analytical solutions to the problem of sound insulation of single-chamber and double-chamber double-glazed windows, which showed good convergence with the experimental results. The proposed method for calculating sound insulation through single- and double-chamber double-glazed windows can be used in engineering calculations after additional studies of internal losses in multilayer glazing, as well as additional measurements of a number of “standard” types of glazing to verify the methodology.

FC39: The influence of social constructivism on children and young adults perspectives of parental young onset dementia: A thematic analysis of the narratives

Background:Western countries have a significant cohort of children (≤ 18) and young adults who live with a parent with a life limiting condition. Children and young adults’ perspectives of certain parental illnesses have been well documented. However, the perspectives of children and younger adults of parental young onset dementia tend to be absent from the academic literature. Older adult children have reported on the impact parental young onset dementia, however, there is a necessity for research with younger adult children and children under the age of eighteen in relation to their perspectives of the condition.Objectives:Utilizing cultural transmission theory, the current research explored if the social and cultural perspective influences the narratives of children and younger adults of parental young onset dementia.Methods:One-to-one interviews were held with children and younger adults (n = 17: 29·41% male) who currently live with (or have lived with) a parent with a formal diagnosis of young onset dementia (with various subtypes). The participants ranged in age from 14 to 33 years old (x̅ = 21·18 years) with n = 6 eighteen years of age or younger (x̅ = 16·17 years). Participant narratives were analyzed using inductive qualitative thematic analysis.Results:Detailed thematic analysis of the participant narratives uncovered five main themes (with related subthemes); making sense; lack of representation; threat to the family system; life has completely changed; systemic psycho-social support and education.Conclusion:It is clear from the current data that the social and cultural perspective can significantly influence the narratives of children and younger adults of parental young onset dementia. Children are faced with more responsibility, shifting roles, changing relationships, and may be forced to postpone educational or employment plans. Furthermore, the social perception of dementia as can act as a barrier to children and young adults accessing and using health and social care providers.

Basic study of practical prediction of sound insulation performance of double-glazed window

Since double-glazed glasses have superior thermal insulation performance compared to single-glazed glasses, they are widely employed for windows in recent buildings. However, the double-glazed glasses used in general buildings have mass-air-mass resonance at around 200-400 Hz, and, at those frequencies, their sound reduction indices are often lower than that of single-glazed glasses that have the same weight. In designing an indoor acoustic environment, it is helpful to have a practical method to predict the sound reduction index of a double-glazed glass window, including the resonance. In this study, at first, measured values of actual double-glazed windows are compared with calculated values of the existing sound transmission theories for double plates and applicability of the theories to double-glazed windows are investigated. Next, in order to obtain a practical prediction of the sound reduction indices of double-glazed windows, some measured values of double-glazed windows are collected from a manufacturer's database and the characteristics of the sound reduction indices are discussed.

Axially-compressed behavior of carbon-FRP strengthening CFT short columns having circumferential void defects

To clarify the viability of externally bonding carbon-fiber-reinforced polymer (FRP) for strengthening the structural integrity of concrete-filled steel tube (CFT) short columns having circumferential void defects, this study comprehensively explores the strengthening effectiveness of various wrapping parameters (i.e., carbon-FRP strength, wrapping layers, and wrapping ratio) on the axially-compressed CFT short columns with various void ratios, material strengths, and geometric parameters by numerical method. Detailed mechanical responses, encompassing failure patterns, load-shortening (N-Δ) curves and stress distribution, are delved to reveal the strengthening mechanisms. Finally, strength prediction formulas for these composite columns are proposed rooted in the ring extension and local force transmission theories. Results show that the presence of initial voids delays the occurrence of steel-concrete contact stress (p) and weakens the p-value at peak load, thus reducing the axial resistance of column. Particularly when the void ratio exceeds 0.2%, the longitudinal strain when the concrete contacts with outer tube is beyond the concrete's peak compressive strain, thus the shape of the N-Δ curve is obviously changed, exhibiting two peaks. Externally bonding carbon-FRP strips can obviously improve the peak load of the column with a void ratio ≤ 0.2%. If the void ratio exceeds 0.2%, externally bonding carbon-FRP strips can also improve the column's second peak load, even exceeding the strength of pure CFT column, while it has no effect on the first load. The formulas proposed herein have a satisfactory accuracy based on the tested validation, which are expected to guide the design of strengthening scheme in engineering.

"It's Not Something That I Realized Until I Started Working Here": A Constructivist Grounded Theory of Knowledge Transmission in Victim Service Providers.

National estimates indicate that intimate partner violence (IPV) impacts people of all social demographics. Although IPV is a pervasive issue, LGBTQ+ individuals and heterosexual men note stark disparities in responses from victim advocates compared to heterosexual women. To highlight the influence of agency training on advocates' perceptions of IPV and diverse survivor populations, interviews were conducted with victim advocates and constructivist grounded theory methods were employed. Analyses show that advocates undergo a three-phase process of learning about IPV when starting at their agencies. Advocate's narratives highlight limitations in training and the importance of workplace experiences in growing understanding of IPV.

Propagation of electromagnetic waves through complex space for astronomical redshift investigation

Space has a complex structure and investigations of any electromagnetic wave transmission theory need to consider the inhomogeneous and anisotropic nature. We have selected two cases for our investigations: regions of pulse energy changes and gravitational deflection. Numerical methods have been developed and examples given to show that these conditions do have their localized effects. But, since the total length of those regions are insignificant in comparison with the total transmission distance involved, their inclusion does not significantly alter the linear relationship between wavelength change and distance travelled. The possible exception is the case of gravitational deflection when the waves have passed through densely populated regions of space. Our findings could be of interest to the current debate on Hubble tension.

A Literature Study for the Spillovers of Quantitative Easing

Quantitative easing, as an unconventional monetary policy, was often adopted by major central banks after the 2008 financial crisis. Different from the conventional monetary policy, that is, the central bank injects liquidity into the financial market by adjusting the benchmark interest rate and open market operations, the core of quantitative easing is to increase the balance sheet of banks in the short term through asset purchases and other behaviors to achieve the purpose of stimulating the economy. From 2008 to 2020, the United States adopted five quantitative easing policies to deal with economic downturn risks. While alleviating its own economic recession, it also had a strong spillover effect on China and other countries. Although quantitative easing has alleviated the economic crisis in the United States in practice, it has had an adverse impact on the entire world economy, making the whole world bear the consequences of the economic crisis together. This article summarizes scholars' research on the role, effectiveness, and spillover effects of quantitative easing policies, and summarizes the factors that affect the size of the spillover effects. Finally, through the analysis of the international transmission theory and transmission channels of inflation, it explores the impact of the US quantitative easing policy on China's inflation rate.

Defect Engineering Activates Schottky Heterointerfaces of Graphene/CoSe2 Composites with Ultrathin and Lightweight Design Strategies to Boost Electromagnetic Wave Absorption

AbstractTo tackle the increasingly complex electromagnetic (EM) pollution environment, the application‐oriented electromagnetic wave (EMW) absorption materials with ultra‐thin, light weight and strong tolerance to harsh environment are urgently explored. Although graphene aerogel‐based lightweight EMW absorbers have been developed, thinner thickness and more effective polarization loss strategies are still essential. Based on the theory of EMW transmission, this work innovatively proposes a high attenuation design strategy for obtaining ultra‐thin EMW absorption materials, cobalt selenide (CoSe2) is determined as animportant part of ultra‐thin absorbers. In order to obtain a dielectric parameter range that satisfies the ultra‐thin absorption characteristics and improve the lightweight properties of EMW absorption materials, a composite of CoSe2 modified N‐doped reduced graphene oxide (N‐RGO/CoSe2) is designed. Meanwhile, the controllable introduction of defect engineering into RGO can activate Schottky heterointerfaces of composites to generate a strong interfacial polarization effect, achieving ultra‐thin characteristics while significantly improving the EM loss capability. In addition, infrared thermal images and anti‐icing experiments show that the composite has good corrosion resistance, infrared stealth, and thermal insulation properties. Therefore, this work provides an effective strategy for obtaining thin‐thickness, light‐weight, and high‐performance EMW absorption materials, embodying the advantages of N‐RGO/CoSe2 composites in practical applications.

The Impact and Mechanism of Corporate ESG Construction on the Efficiency of Regional Green Economy: An Empirical Analysis Based on Signal Transmission Theory and Stakeholder Theory

The Chinese government’s ongoing endeavors to achieve the “low carbon goals” hold immense importance in global emissions reduction. Nonetheless, reducing emissions will inevitably cause economic losses. Therefore, the pursuit of green economic efficiency is regarded as an effective tool to mitigate the economic losses during emission reduction. Synchronously, the realization of green economic efficiency is essential for sustainable development. With the increasing awareness of regional green development, emphasis companies place on environmental, social, and corporate governance (ESG), which contributes to corporate ESG construction, could become a novel advantage in terms of attracting investors. Additionally, it could have a lasting impact on corporate green technological innovation, thereby enhancing the efficiency. Based on the data of A-share listed companies in China from 2009 to 2019, this study analyzes the effect of corporate ESG construction on the efficiency of regional green economy as well as its mechanism. The research findings demonstrate a significant positive impact of corporate ESG construction on the efficiency of regional green economies. Specifically, each unit improvement in corporate ESG construction is associated with an approximate 0.7% increase in the efficiency of the regional green economy. The conclusion can be drawn after robustness testing. Notably, the effect of corporate ESG construction is more pronounced for companies located in the eastern region, state-owned enterprises, and high-polluting industries. In terms of the underlying mechanism, corporate ESG construction facilitates regional green economic efficiency by fostering corporate green technological innovation. Furthermore, it is observed that environmental regulations have a negative moderating influence on corporate ESG construction, which in turn affects regional green economic efficiency. When examining the decomposed variables of regional green economic efficiency, the impact of corporate ESG construction on regional green scale efficiency is found to align with its overall effect on regional green economic efficiency. This study contributes to the existing research on corporate ESG construction and regional green economic efficiency, offering valuable insights to guide companies in enhancing both aspects. Building upon the conclusions drawn, we will provide policy recommendations from the perspectives of the company itself, corporate investors, and the government. These recommendations aim to facilitate improvements in corporate ESG construction and foster the enhancement of regional green economic efficiency.
