Field experiment was conducted at Periyanarkunam during Navarai 2021. The main treatments comprised three direct seeded rice establishment methods viz., dry, drum and manual wet seeded rice. The sub treatments are nine weed management practices and are made up with combination of herbicides with hand weeding viz., application of bensulfuron methyl 0.6% + pretilachlor 6% GR @ 10 kg ha-1 on 8 DAS (Days After Sowing) (PE), application of triafamone 20% + ethoxysulfuron 10% WG @ 200 g ha-1 on 12 DAS (EPoE), application of metsulfuron methyl 10% + chlorimuron ethyl 10% @ 20 g ha-1 on 25 DAS (PoE), twice hand weeding on 25 and 45 DAS and unweededcontrol. Among the main treatments drum seeded rice recorded the lowest weed population, dry matter production, the highest weed control efficiency and the highest grain yield which is on par with manual wet seeded rice. However, manual wet seeded rice led to higher cost of cultivation with lower benefit cost ratio. Hence, drum seeded rice is an economically feasible method of direct seeded rice establishment compared to others. Regarding the weed management practices evaluated application of bensulfuron methyl 0.6% + pretilachlor 6% GR @ 10 kg ha-1 on 8 DAS (PE) fb (followed by) application of metsulfuron methyl 10% + chlorimuron ethyl 10% @ 20 g ha-1 on 25 DAS (PoE) fb hand weeding on 45 DAS (S8) registered the similar trend. Hence, drum seeded rice coupled with S8 is an economically feasible method for effective control of weeds.

Understanding the various characteristics of rainfall in the current era of global warming requires investigating changes in rainfall patterns and events at the regional and district levels historically for predicting futuristic changes. This knowledge will be valuable for developing policy plans for rainfed agricultural states like Odisha, which is also highly vulnerable to floods and droughts. The changing climatic scenario and its impact on various sectors of the economy have emerged as one of the greatest challenges before scientists and policy makers all over the world in the twenty-first century. The impact of climate change is expected to be different in different parts of the globe. Some regions and economic systems may explore positive impacts, whereas others may experience losses due to climate change. The present study in assessing the futuristic changes in seasonal precipitation and solar radiation helps to determine the impact of climate change on coastal districts of Odisha state. Where rainfed crops are grown in a large scale in coastal districts of Odisha, rainfall and solar radiation are two important weather variables that drive crop growth and development that greatly influence the Kharif agricultural productivity, these two parameters are considered for the current research. The Coupled Model Intercomparison Project Phase 5 (CMIP5) has been used to derive the futuristic projections of seasonal rainfall and solar radiation for the years 2030, 2050, 2070, and 2090 under four different Representative Concentration Pathways (RCP) scenarios 2.6, 4.5, 6.0 and 8.5. The results of the present study showed an increasing trend of solar radiation in the future by about a maximum of +2.60 MJ/day in Puri district by 2090 under RCP 8.5 scenario. For the year 2090, there is a maximum decrease of rainfall by -399.05 mm. under RCP 2.6 scenario in the Puri district and by -394.42 mm. under RCP 8.5 scenario in Kendrapara district.

The adolescents are essentially confident in their identity at this point. They begin to feel optimistic about the future. Interpersonal relationships refer to the strong links that individuals form with their teachers, family, and peers. Therefore, the proposed study aimed to assess the interpersonal relationship among late adolescents in Udaipur City, Rajasthan. The 85 statements that made up the Interpersonal Relationship Scale (IRS) focused on particular interpersonal relationship aspects. Experts in the field assessed the Interpersonal Relationship Scale to determine its content validity, and a pilot study was used to evaluate the scale’s reliability. Using a straightforward random sampling technique, a total of 360 late adolescents, aged 19 to 21, were chosen from several universities located in the city of Udaipur, Rajasthan. The data was gathered by the researcher via a survey. To determine the research findings, appropriate statistical techniques, such as frequency and percentage, were applied to the data that was gathered. Following data analysis and comparison, the research findings showed that the majority of late adolescents had good interpersonal relationships with their siblings, friends, peers, and teachers. One of the main challenges in this study was coordinating the integration of many data sources to guarantee thorough analysis. In my contribution to the conversation, I also emphasized the significance of tackling heterogeneity in data and proposed some approaches to increase data interoperability in order to enhance research outputs.

Sesame is mainly cultivated under traditional, low-input agro-systems. However, Adequate application of nitrogenous fertilizers not only improves the crop yield but also maintains soil N status and thus sustains productivity. The experiment was carried out during the kharif season 2015 to 2017 in a randomized block design with four replications. There were five graded levels of nitrogen application viz.,0, 30, 37.5, 45 and 60 kg N ha-1. In coarse-textured, low-nitrogen status soil with an average nitrogen content of 106.45 kg/ha, the study found that sesame seed yield increased significantly with nitrogen application up to 45 kg N/ha.The increase in mean seed yield was 19.23, 24.52, 39.26, and 41.18 percent and in mean stalk yield was 19.59, 23.81, 30.62, and 34.64 percent due to the application of 0, 30, 37.5, 45, and 60 kg N/ha, respectively over control. The mean N-uptake also increased with N application. The mean N-use efficiency varied from 43.10 to 52.38 percent being the maximum (52.38 %) with the application of 45 kg N/ha. The mean post-harvest available N status was 105.43, 107.51, 108.11, 109.15, and 110.23 kg/ha at 0, 30, 37.5, 45 and 60 N/ha, respectively. The economic data analysis revealed that the benefit-cost ratio also increased with nitrogen application and was 0.93, 1.10, 1.15, 1.27, and 1.28 at 0,30, 37.5, 45 and 60 kg N/ha, respectively. Application of 45 kg N/ha was optimum for the cultivation of sesame crop yield, soil N fertility status, and economics under coarse textured low nitrogen status soils.

Rasagolla (a sweet syrup cheese ball) most popular in the regions of South Asia, manufactured from Channa (a precipitate obtained by heat and acid coagulation of milk). The shelf life of Rasagolla at ambient temperature, in sugar syrup is 2 days. The mostserious constraint for shelf life enhancement is the activity of microorganisms. A study has been carried out to enhance the shelf life of Rasagolla by microwave treatment. Rasagolla was prepared under aseptic conditions in the laboratory as per the standard procedure. All the samples of Rasagolla were packed in 16 glass containers. Eight samples were tyndallized and others were kept as control. Standard Plate Count, Coliform Count and Yeast and Mould Count analysis were carried out in tyndallized and control Rasagolla. Sensory evaluation on a nine-point Hedonic Scale was done for treated and untreated products stored at ambient conditions (30 ˚C) at 0 day, 7th, 21st, 28th and till they were acceptable based on organoleptic test and consumer acceptance. It was observed that the shelf life of Rasagolla was extended by 28 days and beyond at room temperature. The different microbial counts are also within the permissible limit in microwave products than control. It has been concluded that the microwave treatment process in Rasagolla is suggested to enhance the shelf life of the product up to 15 days in room temperature.

Climate change poses significant challenges that necessitate the development of policies to manage aggregate input and social costs. To formulate such policies, an analysis of the factors and their current trends must be conducted. This study explores the factors influencing climate change and provides insights into their impacts through changes in arable land and greenhouse gas (GHG) emissions in India from 1990 to 2020. Utilizing time series analysis, this study examined trends in GHG emissions from agriculture and developed a simulation model to estimate overall GHG emissions through methane and nitrous oxide emissions. The results indicate that enteric fermentation and agricultural soil are major contributors to methane and nitrous oxide emissions, respectively, with enteric fermentation contributing approximately 69.33% and agricultural soil contributing approximately 97.66% to methane and nitrous oxide emissions, respectively. Additionally, a higher growth rate was observed for nitrous oxide emissions than for methane emissions, with nitrous oxide emissions showing a 161% increase from 1960 to 2010. Furthermore, a positive correlation (r=0.587) between GHG emissions and changes in the annual mean temperature underscores the direct impact of agricultural emissions on climate dynamics in India, with a regression coefficient factor of 0.176. It is estimated that the overall GHG emissions from agriculture through methane and nitrous oxide emissions will be approximately 695.87 to 818.73 MMTCDE in the year 2030, while the change in annual mean temperature is estimated to be approximately 1.65 ± 0.58o C from 1990 to 2030 in India. This study faces challenges such as uncertainties in long-term climate projections and emission estimates, variability in regional agricultural practices, and the need for more granular data. These findings highlight the urgent need for effective mitigation strategies within the agricultural sector to address the growing threat of climate change.

Authors: Hasna Dinda Aulia , Novianti Nurlita
Published: December 2024

Increased competition forces companies to prepare accurate financial statements. However, this situation also encourages unethical practices, such as financial reporting fraud or manipulation. By analyzing the audit committee’s function as a moderating variable, this study seeks to ascertain the impact of the notion of fraud on financial statement fraud. Six elements make up the theory: opportunity, pressure, capability, hubris, rationalization, and collusion. Financial statement fraud is quantified using the F-Score Model. Forty-three construction businesses that were listed on the Indonesia Stock Exchange between 2020 and 2022 are included in the sample. A component of the selection process was purposive sampling. Statistical Product and Service Solutions version 25 was used to process the results of the moderating regression analysis. The findings indicate that while opportunity, rationalization, and arrogance have little influence on financial statement fraud, cooperation does. On the other hand, capability and pressure have a beneficial impact. Furthermore, the audit committee does not regulate financial statement fraud via rationalization and arrogance; Rather, it does so through pressure, opportunity, capacity, and collaboration. Businesses should consider the factors that affect financial statement fraud detection, according to the study’s findings.

Processing piano audio: research on an automatic transcription model for sound signals
Authors: Wang Peng , Dai Ning
Published: December 2024

Automatic transcription of sound signals can convert audio to musical notes, which has significant research value. This paper extracted dual-channel constant Q transform (CQT) spectra from piano audio as features. In the design of the automatic transcription model, a CNN was employed to extract local features and then combined with a Transformer model to obtain global features. A CNN-Transformer automatic transcription model was established using a two-layer CNN and three-layer Transformers. Experiments were conducted on the MAPS and MAESTRO datasets. The results showed that dual-channel CQT outperformed short-time Fourier transform (STFT) and mono CQT in auto-transcription. Dual-channel CQT achieved the best results on frame-level transcription for the MAPS dataset, with a P value of 0.9115, an R value of 0.8055, and an F1 value of 0.8551. A sliding window with seven frames yielded the best transcription results. Compared with the deep neural network and CNN models, the CNN-Transformer model demonstrated superior performance, achieving an F1 value of 0.8551 and 0.9042 at the frame level for MAPS and MAESTRO datasets, respectively. These findings confirm the designed model's reliability for automatic piano audio transcription and highlight its practical applicability.

Published: December 2024

Landslides, as a common geological hazard, pose a significant threat to critical infrastructure such as pipelines. With numerous large-scale engineering projects in China crossing active fault zones, the impact of geological hazards on the safe operation of pipelines is becoming increasingly prominent. To accurately assess the impact of landslides on pipelines, this study employs the open-source DualSPHysics code and constructs a three-dimensional numerical model of landslide impact on pipelines based on the Smoothed Particle Hydrodynamics (SPH) method. The study conducts a quantitative analysis of key factors such as sliding displacement and landslide scale, thoroughly exploring the mechanisms by which landslides affect pipelines. The results indicate that as the landslide displacement increases, the rate at which the pipeline's stress increases accelerates, and the rate of stress decrease after reaching the peak also accelerates. Additionally, when the width of the landslide mass increases, its volume correspondingly increases, leading to a significant enhancement in the impact force experienced by the pipeline. Furthermore, the study analyzes the impact of different initial distances between SPH particles on the pipeline to optimize the accuracy and computational efficiency of the simulations. This research not only provides new perspectives and approaches for assessing pipeline safety but also holds significant implications for enhancing pipeline disaster resistance and guiding design and safety assessments in geological engineering and infrastructure projects.

Vibration response analysis of hydraulic pipeline based on finite element method
Authors: Han Xin , Chi Jinping
Published: December 2024

The oil pipeline is a critical component that influences the vibration and noise levels of the hydraulic system. Inadequate design may result in resonance or leakage issues, rendering it susceptible to external vibration excitation. To enhance the reliability of the hydraulic pipeline, simulations and analyses were conducted on its modal, harmonic response, and fatigue characteristics. Based on the results of harmonic response analysis and strength analysis, an effective reinforcement scheme was proposed and validated. By inputting the acceleration load to the pipeline system for frequency response analysis, the influence of different excitation forces on the pipeline stress can be determined. The findings indicate that pipeline vibration primarily occurs in the outlet pipe of the transmission, with significant stress and vibration displacement observed at the thermostat valve support. Following structural improvements, there was a notable reduction in stress levels at the transmission outlet pipe, along with a shift in maximum stress position due to additional support. This enhancement has improved both structural stiffness of the outlet pipe and overall stability of the pipeline system.

Published: December 2024

Grouting reinforcement method is one of the effective methods commonly used in slope reinforcement. At present, grouting reinforcement technology is mostly aimed at sandy soil and clay, and the research on gravel soil is still relatively few. At the same time, because of the strong concealment of slurry diffusion in grouting reinforcement, the process and law of slurry diffusion in grouting process has always been a difficult problem. In this paper, through numerical simulation analysis and indoor simulation grouting test, the law of slurry diffusion flow in slope gravel soil grouting is analyzed, and compared with the law of slurry diffusion in sand. At the same time, the pressure distribution along the slurry diffusion process and the changes of soil parameters before and after grouting are also analyzed. The results show that the final diffusion radius of slurry is proportional to the water-cement ratio and grouting pressure of cement slurry, and the diffusion radius of slurry in slope gravel soil is much larger than that in sand. In slurry diffusion, the pressure along the road gradually attenuates with slurry diffusion, and its attenuation rate is inversely proportional to the water-cement ratio of cement slurry. The attenuation rate in slope gravel soil layer is much slower than that in sand layer. After the slope gravel soil layer and sand soil layer are strengthened by grouting, the porosity of the soil layer decreases and the compressive strength increases. The research results indicate the diffusion law of grouting slurry in slope gravel soil and provide reference for similar engineering designs.

Research on the vibration noise matching strategy of range-extended electric vehicle
Authors: Zhang Hongjun , Shi Xiangnan , Chen Jingchang
Published: December 2024

Range-extended electric vehicles (REEVs) face more intricate noise, vibration, and harshness (NVH) challenges compared to traditional fuel and pure electric vehicles, primarily due to the complexities introduced by range extender control strategies. Poorly designed control logic can result in issues such as excessive noise during acceleration and engine roar, which are not only costly to rectify but also time-consuming. This article simplifies the theoretical model of range extender systems by treating the range extender as a single excitation source. By monitoring the vehicle's overall status, the system adjusts the output torque and crankshaft speed to evaluate the vibration and noise at critical points within the vehicle. This proactive approach helps to preemptively optimize NVH performance under various operating conditions, thereby minimizing the need for subsequent adjustments to the suspension, transmission, intake, and exhaust systems. As a result, it significantly reduces costs and accelerates the project's development timeline.

In order to evaluate ride performance of an electric vehicle (EV) active suspension systems (ASSs), a 8-DOF full-vehicle dynamic model of EV under random road excitation is set for control ASSs of EV to enhance ride comfort. A PID controller is proposed for control. The parameters of the PID controller are tuned using the Ziegler-Nichols method. The achieved results indicate that the root mean square (RMS) values of the vertical driver's seat, vehicle body, pitching and rolling acceleration responses with ASSs using the proposed controller respectively reduce by 31.12 %, 24.76 %, 15.00 %, and 11.59 % in comparison with passive suspension systems (PSSs) under the investigated condition. In addition, these results will be the basis for optimizing the parameters for PID controller to improve the ride performance of ASS.

Authors: Gong Xiaoping , Cheng Liang , She Yangjia , Zheng Tingting
Published: December 2024

The transition to electric vehicles (EVs) has heightened the significance of secondary noise sources, such as buzz, squeak, and rattle (BSR), which can detract from vehicle quality and customer satisfaction. Among these, body squeaking noise, particularly during the electro-coating (e-coating) process, presents a notable challenge due to its impact on vehicle acoustic comfort. Despite advancements in automotive noise, vibration, and harshness (NVH) control, the specific viscoelastic mechanisms contributing to squeaking noise under varying thermal and mechanical conditions remain inadequately understood. This study addresses these gaps by employing the Maxwell Viscoelastic Model to investigate the time-dependent mechanical behavior of body-in-white (BIW) coatings during the e-coating process. Key finding indicates that the glass transition temperature (Tg) of the coating material plays a critical role in noise occurrence, particularly under high-temperature conditions and road-induced vibrations. This research contributes novel insights to the field by integrating theoretical analysis with empirical data to enhance the understanding of viscoelastic properties in automotive coatings.

Published: December 2024

Concrete filled steel tubular (CFST) structure can effectively combine the properties of steel tube and concrete. The structural displacement, internal force and energy consumption of the pier under earthquake are calculated by time history analysis method. The seismic performance of CFST composite pier after the corresponding structural parameters are changed is predicted. Under the given seismic load, the pier concrete and steel tube have different degrees of plasticity. Concrete damage consumes the energy input into the structure by the earthquake to a certain extent, and the existence of steel tubes makes the overall stability of the structure better.
