Effect of liquid sloshing in lateral and longitudinal directions on railway tank cars based on an improved equivalent model

Additional slosh forces and moments are generated owing to the movement of the liquid inside a partly filled tank car. The loads may have a great influence on the structure reliability and dynamic performance of the vehicle. An improved equivalent model of liquid sloshing is put forward to obtain the forces and moments of sloshing liquid acting on the tank during the lateral and longitudinal sloshing processes. An improved method is proposed to obtain the equivalent masses and stiffness for the improved equivalent model. The equivalent model is integrated into the multi-body dynamic model of a railway tank car with 68 degrees of freedom. Furthermore, the equivalent liquid-vehicle model is used to investigate the effects of fluid sloshing on dynamic characteristics. The influence of the filling ratio on the dynamic response of the tank car is discussed based on the forces and the corresponding moments between the tank car body and the liquid in different layers. The railway tank car is obviously influenced by the liquid sloshing during passing the curved and sloped tracks. The influence of liquid sloshing on the pitching motion of the tank is heavy if the tank is about half filled. The derailment coefficient and the wheel unloading rate are slightly influenced by the filling ratio of tank cars on curved tracks while the indices of the tank cars on sloped tracks are the greatest if the filling ratio is 40%.

Modeling Apsidal Motion in Eclipsing Binaries Using ELC

Apsidal motion is the precession of the line of apsides in the orbit of a binary star due to perturbations from General Relativity (GR), tides, or third-body interactions. The rate of precession due to tidal effects depends on the interior structures of the stars, and as a result, binaries in which this precession occurs are of great interest. Apsidal motion is observed through the analysis of eclipse times, which reveal small changes in the average interval between successive primary and secondary eclipses, taking all available observed times of eclipse and yielding an estimate of the apsidal rate. Given that this is a single observed quantity, various degeneracies are unavoidably present. Ideally, one would have a model that predicts eclipse times given the orbital and stellar parameters. These parameters for a given binary could then be computed using least squares, provided a suitably large number of eclipse times. Here we use the eclipsing light curve (ELC) program as such a model. The Newtonian equations of motion with additional force terms accounting for GR contributions and tidal distortions are integrated, yielding precise sky positions as a function of time. Times of mid-eclipse and instantaneous orbital elements are computed as a function of time. In this paper, we outline the method and compare numerically computed apsidal rates with standard formulae using a set of 15 binaries based on real systems. For our simulated systems, the derived apsidal rates agree with the standard formula.

Effective managerial communication should be practiced by a leader with authority and a significant role in the management of Geopark Rinjani Lombok.

Influence of the rotation characteristics of the controllable speed casing on the flow stability of a high-load compressor stage

The controllable speed casing (CSC) has been confirmed as a novel type of casing treatment technology that is capable of designing the original fully fixed casing structure into two parts, i.e., the rotatable ring section and the stationary ring section. A range of circumferential additional forces will be imposed on the tip region of the rotor by regulating the rotation direction and rotation speed of the rotatable ring section, such that different effects will be exerted on the aerodynamic performance and flow stability at the compressor stage. As indicated by the results of this study, when the rotation direction of the CSC was opposite to that of the rotor, the relative increase of the stable operating margin changed from positive to negative when the casing rotation speed was increased and accounted for 60% of the rotor speed. When the CSC exhibited the identical rotation direction to the rotor, the stability turned out to be more significantly increased. With the decrease of circumferential pressure gradient in the tip region, the original driving force of the tip leakage flow reduces, and the flow capacity was increased. The stable operating margin was increased with the rise of the rotation speed of the CSC, and the stable operating margin was increased by up to 45.44% at casing rotation speed accounting for 100% of the rotor speed.

Effect of molecular environment on asphaltene aggregation: a molecular dynamics study

Asphaltene deposition poses a significant threat to the safe production of crude oil as it tends to occur in forming porous media, wellbores, pipelines, and refining equipment. It is also responsible for the high viscosity of crude oil, making it challenging to recover heavy crude oil. This study investigates the impact of aliphatic chain length on asphaltene aggregation and the molecular properties of organic solvents and dispersants interacting with asphaltenes. To achieve this, two model asphaltenes, M1 and C5Pe, were used in molecular dynamics simulations using radial distribution function, root means square displacement, diffusion coefficient, solubility parameter, cohesion energy density, and interaction energy as characterization parameters. The simulations revealed that the aggregation onset of C5Pe and M1 occurs at 2–5 Å at room temperature and pressure, and π–π stacking is the primary mode of aggregation, with the presence of heteroatomic groups providing additional forces for stable aggregation. Additionally, it was found that the π–π interactions weakened with the increase of the side chain length. The study also investigated the molecular behavior of asphaltenes in six organic solvents and found that M1 was more soluble in aromatic solvents than C5Pe, and undesirable solvents could induce asphaltene aggregation. Furthermore, the effect of five dispersants on asphaltene aggregation was explored, with PIBSI, BEHP, B-DBSA, CTAB, and benzoic acid showing decreasing dispersing ability in that order at lower concentrations. However, at higher concentrations, the effect of some dispersants diminishes and triggers self-aggregation behavior.

Confront f(R,T)={mathcal {R}}+beta T modified gravity with the massive pulsar {textit{PSR J0740+6620}}

Many physically inspired general relativity (GR) modifications predict significant deviations in the properties of spacetime surrounding massive neutron stars. Among these modifications is f({mathcal {R}}, {mathbb {T}}), where {mathcal {R}} is the Ricci scalar, {mathbb {T}} is the trace of the energy–momentum tensor, the gravitational theory that is thought to be a neutral extension of GR. Neutron stars with masses above 1.8 M_{odot } expressed as radio pulsars are precious tests of fundamental physics in extreme conditions unique in the observable universe and unavailable to terrestrial experiments. We obtained an exact analytical solution for anisotropic perfect-fluid spheres in hydrostatic equilibrium using the frame of the linear form of f({mathcal {R}},{mathbb {T}})={mathcal {R}}+beta {mathbb {T}} where beta is a dimensional parameter. We show that the dimensional parameter beta and the compactness, C=frac{2GM}{Rc^2} can be used to express all physical quantities within the star. We fix the dimensional parameter beta to be at most beta _1=frac{beta }{kappa ^2}= 0.1 in positive values through the use of observational data from NICER and X-ray Multi-Mirror telescopes on the pulsar {textit{PSR J0740+6620}}, which provide information on its mass and radius. The mass and radius of the pulsar {textit{PSR J0740+6620}} were determined by analyzing data obtained from NICER and X-ray Multi-Mirror telescopes. It is important to mention that no assumptions about equations of state were made in this research. Nevertheless, the model demonstrates a good fit with linear patterns involving bag constants. Generally, when the dimensional parameter beta is positive, the theory predicts that a star of the same mass will have a slightly larger size than what is predicted by GR. It has been explained that the hydrodynamic equilibrium equation includes an additional force resulting from the coupling between matter and geometry. This force partially reduces the effect of gravitational force. As a result, we compute the maximum compactness allowed by the strong energy condition for f({mathcal {R}}, {mathbb {T}})={mathcal {R}}+beta {mathbb {T}} and for GR, which are C = 0.757 and 0.725, respectively. These values are approximately 3% higher than the prediction made by GR.. Furthermore, we estimate the maximum mass Mapprox 4.26 M_{odot } at a radius of Rapprox 15.9 km for the surface density at saturation nuclear density rho _{text {nuc}} = 2.7times 10^{14} g/cm^3.

Chemical and structural induced ductile-to-brittle transition in electrospun silica nanofiber membranes

Electrospun silica nanofiber membranes show a high potential in many advanced environmental applications. However, little is known about their mechanical performance which could be a limiting factor for further innovation. It is shown in this work that silica nanofiber membranes have a completely different deformation behavior compared to conventional polymeric/thermoplastic nanofiber membranes, resulting from their significant differences in chemical and physical properties such as fiber interactions and porosity. Furthermore, storage at room temperature initiates remarkable changes in failure mechanisms, depending on the storage humidity, which can be accelerated via a thermal treatment. These changes are linked to the structural changes of the membrane resulting from its chemical reactivity towards moisture in the air. Additional interactions and crosslinks are observed, leading to fiber shrinkage and rearrangement. As a result, more contact points are created between nanofibers, creating additional friction forces and, as such, a complete shift in mechanical properties towards a stronger, stiffer, and more brittle material (tensile strength of 14.0 ± 3.8 MPa vs. 3.1 ± 0.4 MPa and failure strain of 0.9 ± 0.2% vs. 24.2 ± 1.0%). The silica nanofiber membranes thus allow mechanical tunability via altering the storage or treatment conditions.

Left Head Rotation as Alternative to Difficult Tracheal Intubation: Randomized Open Label Clinical Trial.

Tracheal intubation is a life-saving intervention not only for physicians but also for allied health workers. Optimizing the patient's head and neck position for the best glottic view is a crucial step that accelerates tracheal intubation. The left head rotation maneuver has been recently described as an innovative approach to tracheal intubation with marked improvement in glottic visualization and can be an alternative before proceeding to a surgical airway. This study compared the glottic view and intubating conditions in the sniffing position versus left head rotation during direct laryngoscopy. This randomized, open-label clinical trial enrolled fifty-two adult patients admitted to the Baguio General Hospital & Medical Center from September 2020 to January 2021 for an elective surgical procedure requiring tracheal intubation under general anesthesia. Intubation was done using a 45-degree left head rotation in the experimental group (n=26), while the control group (n=26) was intubated using the conventional sniffing position. Glottic visualization and intubation difficulty with left head rotation and sniffing position were assessed using Cormack-Lehane Grade and Intubation Difficulty Scale, respectively. Successful intubation is measured by observing a capnographic waveform in the end-tidal CO2 monitor after placement of the endotracheal tube. There was no significant statistical difference in the clinicodemographic characteristics between the left head rotation and sniffing position groups. There was no statistically significant difference in the Cormack-Lehane Grade, with 85% of patients classified under Grades 1 and 2 in both groups. Also, there were no statistically significant differences in the Intubation Difficulty Scale scores of patients intubated with left head rotation or sniffing position; 30.7% of patients in both groups were easily intubated, while 53.8% in left head rotation and 57.6% in sniffing position groups were intubated with slight difficulty. Similarly, there were no significant differences between the two techniques in any of the seven parameters of the Intubation Difficulty Scale, although numerically fewer patients required the application of additional lifting force [7 (26.9%) vs. 11 (42.3%)] or laryngeal pressure [3 (11.5%) vs. 7 (26.9%)] when intubated with left head rotation. The intubation success rate with left head rotation was 92.3% vs. 100% in the sniffing position, but this difference was not statistically significant. Left head rotation produces comparable laryngeal exposure and intubation ease to the conventional sniffing position. Therefore, left head rotation may be an alternative for patients who cannot be intubated in the sniffing position, especially in hospitals where advanced techniques such as video laryngoscopes and flexible bronchoscopes are unavailable, as is the case in this study. However, since our sample size was small, studies with a larger study population are warranted to establish the generalizability of our findings. In addition, we observed inadequate familiarity among anesthesiologists with the left head rotation technique, and the intubation success rate may improve as practitioners attain greater technical familiarization. This trial was registered in the International Traditional Medicine Clinical Trial Registry (ISRCTN23442026).

Особенности пожароопасного сезона 2022 года в Курганской области

On the basis of a comprehensive analysis of the weather conditions, the necessary extinguishing equipment provided and the additional forces and means involvement, the dynamics of the number of forest fires with the area covered during the fire season have been shown in the article. It was established that in 2022, 468 forest fires were recorded in the forest fund of the Kurgan region and their area was 123 709,48 ha. Thanks to the involvement of additional forces and fire extinguishing equipment, despite adverse weather conditions, it was possible to reduce the number of forest fires by 2,8 times compared to 2021 and reduce the number of large fires by 2 times. At the same time, in 2022 an increase in the area covered by fires and the average area of forest fires were recorded. It has been established that in the region there is a tendency to increase the burning of the forests which necessitates more strict control over compliance with fire safety rules. It is recommended to timely introduce a regional emergency mode and more quickly maneuver the fire forces and means. Taking into account that the part of the forest fund part is contaminated with radionuclides as well as swampiness, it is recommended to use aviation forces and means more widely in protecting forests from fires.

A method for the estimation of oil film parameters in an asymmetric rotor-bearing system

PurposeAsymmetric rotating machinery supported by oil film bearings is relatively common in practical applications. The purpose of this study is to propose a method for estimating the oil film parameters of the bearings in an asymmetric rotor-bearing system.Design/methodology/approachThe proposed method requires the finite element model and translational displacement responses at the center of mass and bearings locations to form a regression equation to estimate the unknown parameters. Due to the transverse stiffness of the asymmetric rotor is not symmetrical, the analysis and parameter estimation procedures are performed in a rotating coordinate. Numerical simulations were carried out to illustrate the vibration characteristics of the asymmetric rotor system. The proposed method is applied to the simulated responses to estimate the assumed oil film parameters. The influence of the estimated parameter deviations on the rotor dynamic characteristics is discussed.FindingsThe vibration characteristics of asymmetric rotors are different from those of symmetrical rotors. The bearing parameters estimated by the proposed method are close to the assumed values, within a maximum error of 9%. The deviations of the estimated parameters have little effect on the vibration characteristic of the rotor system.Originality/valueThe proposed method does not require changing the rotational speed or applying additional excitation force to the rotor, which is suitable for the field test.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/ILT-04-2023-0111/

The effect of fatigue on spike jump biomechanics in view of patellar tendon loading in volleyball.

Patellar tendinopathy (PT) is a highly prevalent overuse injury in volleyball and is often linked with overloading of the patellar tendon. Little is known, however, about whether and how patellar tendon loading is affected by fatigue during the most challenging jump activity in volleyball. Therefore, this study investigates the effect of a high-intensity, intermittent fatigue protocol on movement alterations in terms of patellar tendon loading during a volleyball spike jump. Forty-three male volleyball players participated in this study. Three-dimensional full-body kinematics and kinetics were collected when performing a spike jump before and after the fatigue protocol. Sagittal plane joint angles, joint work and patellar tendon loading were calculated and analyzed with curve analyses using paired sample t-tests to investigate fatigue effects (p < 0.05). Fatigue induced a stiffer lower extremity landing strategy together with prolonged pelvis-trunk flexion compared to baseline (p = 0.001-0.005). Decreased patellar tendon forces (p = 0.001-0.010) and less eccentric knee joint work (-5%, p < 0.001) were observed after the fatigue protocol compared to baseline. Protective strategies seem to be utilized in a fatigued state to avoid additional tensile forces acting on the patellar tendon, including proximal compensations and stiff lower extremity landings. We hypothesize that players might be more prone for developing PT if eccentric patellar tendon loads are high in the non-fatigued state and/or these loads are somehow not decreased after fatigue.

Research directions for reducing the resistance force to the movement of a wheeled power vehicle

The article discusses the efficiency of the use of energy means largely depends on the traction properties developed by them, which directly affects the realized traction force on the hook. Studies have established that the tangential thrust force realized by the energy means is spent on overcoming the forces of resistance to movement and overcoming the forces of resistance of the agricultural machine. In turn, the resistance strength of an agricultural machine largely depends on the physical and mechanical properties of the soil, the width of the grip and the speed of movement, especially on clay and heavy loamy soil types. It should be noted that this type of soil has a significant impact on the strength of resistance to movement, which is due to the fact that at the same time there is an additional force associated with overcoming the viscosity forces that arise between the soil particles when they are separated from each other. In addition, when the soil adheres to the propellers of the energy vehicle, there is an additional energy consumption for the promotion of additional flywheel masses with an increase in the mass of the propeller. Research and industrial observations have established that one of the ways to reduce the force of resistance to movement on clay and heavy loamy soils is the timely cleaning of wheel movers from the soil adhering to them. In the presented article, the issue of reducing the force of resistance to movement due to purification (purification) of the tire tread of the wheel mover is considered.

Numerical analysis of high temperature potassium heat pipe under marine condition

A heat pipe (HP) is a two-phase heat transmission device with very high effective thermal conductivity, extensively employed in multiple industrial fields. In the nuclear engineering area, numerous experimental and numerical studies are widely produced for its thermal behavior performance in high temperatures. In this paper, a HP that potassium as the working fluid with a capillary wick structure was taken into consideration under marine conditions through numerical simulations. The physical properties of potassium and the additional force method of rolling motion are utilized with user-defined functions (UDFs). This CFD model verified with available experimental results, is employed to investigate the influence of HP surface wall temperature distribution and thermal resistance by several parameters including inclination angle, filling ratio (FR), and rolling period. Besides, the charts of phase change and wall temperature distributions are visible with the help of CFD simulation under static and rolling condition. Therefore, the high temperature HP application of design and evaluation is provided as a reference in present work under marine condition.

Application Of Inverted Pendulum in Laplace Transformation of Mathematics Physics

The Laplace transform is a technique used to convert differential equations into algebra, it is often used for the analysis of dynamic systems and inverted pendulum systems. An inverted pendulum is a mechanism that moves objects from one place to another and shows the function of its activity while walking. This system is widely used in various fields, for example in the fields of robotics, industry, technology and organics. In an inverted pendulum there is an inverted pendulum dynamic system with a reading and driving force. The results of the study show that using the Laplace transform can make it easier to find solutions regarding the inverted pendulum system for a variety of conditions, both in the initial conditions and when given an additional force or load. The application of the Laplace transform is useful for understanding how an inverted pendulum system will react to various forces, loads and initial conditions, which can be used to predict how the system will operate in the real world

Dynamic modeling of cylindrical roller bearings by considering non-through defects and additional forces

Cylindrical roller bearings are essential components in rotating mechanical systems, and ensuring their reliable operation is importance. Accurate modeling of cylindrical roller bearing defects is therefore crucial for enabling effective predictive maintenance strategies in various industries. However, previous studies have overlooked the presence of additional forces that occur when rollers enter and exit non-through defects, leading to inaccuracies in bearing vibration calculations. This work proposes a novel model that captures the bearing vibrations during this process, by considering the defect edge feature of the cylindrical roller bearings. The contact force between the roller and the defective ring is calculated by using the non-ideal Hertzian contact theory, while the additional force is characterized by a time-varying function based on the geometric relationship and Hertzian contact theory. To validate the proposed model, comparison work is carried out between the contact forces calculated using this model and those obtained from existing models, demonstrating the significance of the additional force during the process of rollers entering and exiting non-through defects. Furthermore, the effects of the outer ring defect width, length, and edge angle on cylindrical roller bearing vibrations are investigated and discussed. Compared with the previous studies, this work considers both the additional forces caused by the defect and defect edge feature, and combines the non-ideal Hertzian contact theory to obtain a more reasonable dynamic of the defective cylindrical roller bearings.

Numerical simulation of arc-droplet-weld pool behaviors during the external magnetic field-assisted MIG welding-brazing of aluminum to steel

The alternative longitudinal external magnetic field (LEMF) was verified to be effective to enhance the spreading and wetting capacity of the molten aluminum metal in metal inert gas (MIG) welding-brazing of aluminum to steel. This study proposed a three-dimensional arc plasma-molten aluminum-solid steel coupled model of LEMF-assisted MIG welding-brazing of aluminum to steel. The effect of LEMF on the arc plasma, metal transfer, weld pool behavior and temperature evolution at the brazing interface was analyzed. It was found that the alternative LEMF caused the periodical swinging of the arc plasma along the weld width direction and increased the velocity of the arc plasma under the undetached filler metal. The droplet velocity was decreased due to the deflection of the arc plasma force and the additional electromagnetic force. The periodical inclination of the droplet and arc plasma increased the lateral flow velocity of the molten aluminum metal so the spreading ability of the liquid aluminum on the surface of steel was improved. The heating area at the brazing interface between the molten aluminum and solid steel was expanded to improve the wetting of the molten metal. Besides, the peak temperature at the brazing interface decreased, which may suppress the growth of the intermetallic compound.

Spatially expanded built-in electric field via engineering graded junction enables fast charge transfer in bulk MnO@Mn3O4 for Na+ supercapacitors

Built-in electric field (BIEF) has recently emerged as a promising strategy for promoting charge transfer by supplying additional coulomb forces. However, the challenge lies in the intelligent control over the thickness and intensity of BIEF to augment these Coulomb forces, thereby enhancing charge transfer in bulk electrodes. Here we deliberately engineer a graded MnO@Mn3O4 junction characterized by a spatially intensified BIEF to accelerate charge transfer over an extended atom layer thickness. This graded MnO@Mn3O4 junction exhibits a phase transition gradient, characterized by a steady decline in Mn valence and work function from shell to core, giving rise to an intense BIEF across the junction. The enhanced BIEF should be ascribed to the spatially accumulated polarization, resulting in an increase in electron delocalization and a decrease in the energy barrier for ion transfer. As a result, the MnO@Mn3O4 manifests improved capacity and rate performance. This work highlights the significance of modulating the BIEF’s thickness and intensity to facilitate charge transfer, thereby pushing the boundaries of electrochemical energy storage.

Carbon nanotubes doped cellulose nanocomposite film for high current flexible piezoelectric nanogenerators

Cellulose is a highly abundant biomass resource and can be used as raw material for green electronics. The carbon nanotubes (CNTs) doped cellulose-based nanocomposite film (CNTs/Cellulose) was prepared in this paper. The cellulose in CNTs/Cellulose belongs to the type I crystal form. The CNTs are filled in the fiber network and covered on the cellulose fiber surface. The maximum thermal degradation temperature of CNTs/Cellulose is 142 °C higher than that of cellulose. A flexible piezoelectric nanogenerator (PENG) with a high current of milliampere level was made from CNTs/Cellulose. The PENG shows an output current of 6.19 mA and a current density of 1.55 mA/cm2. Furthermore, the PENG can successfully drive electronic devices such as LED lights, electronic watches and calculators under its own gravity without applying additional force. This work provides a new idea for the development of novel PENG.

Skin-adhesive lignin-grafted-polyacrylamide/hydroxypropyl cellulose hydrogel sensor for real-time cervical spine bending monitoring in human-machine Interface

Developing a straightforward method to produce conductive hydrogels with excellent mechanical properties, self-adhesion, and biocompatibility remains a significant challenge. While current approaches aim to enhance mechanical performance, they often require additional steps or external forces for fixation, leading to increased production time and limited practicality. A novel lignin-grafted polyacrylamide/hydroxypropyl cellulose hydrogel (L-g-PAM/HPC hydrogel) with a semi-interpenetrating polymer network structure had been developed in this research that boasted exceptional adhesion to the skin (∼68 kPa) and stretchability properties (∼1637 %) compared to PAM-based hydrogels. By incorporating conductive additives such as silver nanowires and carbon nanocages to construct a bridge-like structure within the hydrogel matrix, the resulting AgC@L-g-PAM/HPC hydrogel exhibited impressive electrical conductivity, surpassing that of other PAM-based hydrogels relying on MXene, with a maximum value of 0.76 S/m. Furthermore, the AgC@L-g-PAM/HPC hydrogel retained its efficient electrical signal transmission capability even under mechanical stress. These make it an ideal flexible strain sensor capable of detecting various human motions. In this study, a smart real-time monitoring system was successfully developed for tracking cervical spine bending, serving as an extension for monitoring human activities.

A dumbbell-shaped 3D flat plate pulsating heat pipe module augmented by capillarity gradient for high-power server CPU onsite cooling

With the development of the data center industry and the increasing power density of servers, it is crucial to remove waste heat from small-area heat sources to ensure the safe and efficient operation of data processing chips. To complement existing studies, in this paper, a novel three-dimensional flat plate aluminum pulsating heat pipe (3D-FPPHP) with four different channel structures for radial heat dissipation of high-power server chips was proposed. The results showed that under the favorable influence of the additional capillarity force provided by the variable diameter channels, the FPPHP filled with acetone can start up easily and has good robustness during variable power operation. When the input power was 150 W, the junction temperature of the heating source could be reduced by 42.49 °C (48.67%) compared to an identical aluminum plate. In addition, a heat sink module based on the proposed 3D-FPPHP with optimal charging ratio was tested in a 1U server chassis. The results showed that it can manage an input power of 300 W (corresponding to a heat flux of 41.15 W/cm2) and achieve a total thermal resistance of 0.2053 °C/W under the premise of ensuring a safe junction temperature of chips below 85 °C.
