The lithium-ion battery (LIB) is an electrochemical energy storage device that can achieve high energy density while retaining high power density. Here, we build a high energy density LIB module with a ∼12.10% increase in energy density over the previous cell. For environmental and safety reasons, several design elements such as electrode thickness, porosity, current density, and particle size were iterated to improve specific capacity and energy density without changing the ambient temperature increment. We have used a simple heat generation system; the temperature raised by ∼18.96% from the room environment was close to 29.74 °C. The specific capacity was also improved by ∼14.56% as compared to commercial LIB. Besides, we used the gassing and plating methods to reduce the integrated Li-ion loss fo...

A number of sources, including schooling, influence the cognition of language teachers. The concept of schooling is identified as the history of teachers' own personal education influences on the teachers’ knowledge, also referred to as apprenticeship of observation (AO). Through further conceptualization of schooling/AO involving the notion of history-in-person, the current multiple case study explored the prior learning experience of two Bangladeshi novice teachers of English: Kamrul and Monabbir (pseudonym), and how these experiences influenced their cognition of language. The findings suggest that the prior learning experience of English teachers has influenced their cognition and has taken on distinctive trajectories. Both AO and anti-apprenticeship of observation (anti-AO) were documented on the basis of the positive and negative English learning experiences of Kamrul and Monabbir at school. The article...

Ultra-Early Cord Decompression in the Emergency Setting and its Impact on Outcome

Emergency Medicine – Open Journal, 2021

Background Traumatic cervical are injuries are very common due to high motility of cervical spine... more Background Traumatic cervical are injuries are very common due to high motility of cervical spine and its vulnerability to traumatic injuries. Optimal time for stabilizing the patients with traumatic spinal fractures remains controversial. It is almost due to different outcomes in various studies and the lack of consensus about it. Here we explain an ultra–early cord decompression that led to complete recovery of a patient with severe cervical cord injury. Case Presentation The patient was a 27-year-old gymnast woman with a recent history of spinal cord injury caused by high jumping with head back and neck hyperextension presented within 2-hours of trauma. As a critical case and lack of advanced radiologic equipment, only cervical spinal radiographs were used for decision-making within the first 3 hours of injury to save the patient’s cord function by surgical decompression. Conclusion Many studies have proposed different intervention times for achieving the optimal result; however,...

Accordingly, the coronavirus outbreak has also a major effect on the emergency department (ED) as it changes the routine ED function. Our main question was what are the main triage challenges in the recent pandemic and how we could overcome these challenges? Therefore, a search of the main Web databases was performed for articles published till May 1st, 2020 using various related keywords. In various steps, the title, summary, methodology, results, and discussion of the selected studies were assessed to find out the recent triage strategies in the COVID-19 outbreak. Hence, all the available and related English review articles, case series, and experimental studies were evaluated. Among 200 studies initially reviewed, 59 met the study criteria for the final assessment. COVID-19 puts a signif...

Experimental Analysis and Simulation of the Dynamic Response of a Propeller Pitch Change Actuator

The subject of this article is restricted to the mechanisms using a hydraulic single acting actuator. They function asymmetrically and are subject to important varying external loads under the full flight envelope. This phenomenon has an impact on their dynamic response. The question of the dynamics of these systems is rarely dealt with because, usually for aircraft applications, there is no real requirement for propeller pitch dynamic control. But, in the case of some applications, such as the Eurocopter X 3 , this dynamic control aspect and the safety aspect of the propeller pitch change mechanism are particularly important, because this mechanism is fully involved in aircraft safety, control and handling qualities. Firstly, this paper gives an explanation of the phenomena applied to the propeller pitch change mechanism and their contributions to its dynamic response. Then, a model of the dynamic response is proposed. Finally, an experimental identification of the pitch change mechanism dynamics concludes this article.

Nonlinear Vibration Solution for an Inclined Timoshenko Beam Under the Action of a Moving Force with Constant/Nonconstant Velocity

The beam's nonlinear governing coupled partial differential equations (PDEs) of motion for the bending rotation of warped cross-section, longitudinal and transverse displacements are derived using Hamilton's principle. To obtain the dynamic response of the beam under the action of a moving force, the derived nonlinear coupled PDEs of motion are solved by applying Galerkin's method. Then the beam's dynamic response is obtained using mode summation technique. Furthermore, the calculated results are verified with those obtained by finite element method (F.E.M.) analysis. In the next step a parametric study on the response of the beam is conducted by changing the magnitude of the traveling concentrated force, its velocity and beam's boundary conditions and likewise their sensitivity on the beam's dynamic response are studied, respectively. It is observed that the existence of quadratic-cubic nonlinearity in the governing coupled PDEs of motion renders hardening/softening behavior on the dynamic response of the beam. Moreover, it is noticed that any restriction on the beam mid-plane stretching will introduce nonlinear behavior in the beam's PDEs of motion.

Using the Euler-Bernoulli beam model, the governing nonlinear PDE of the beam's transverse vibration and also its associated boundary conditions are extracted. These nonlinear motion equation and boundary condition relations are solved simultaneously using four different approximate-analytical solution techniques, namely the method of Multiple Time Scales, the method of Normal Forms, the method of Shaw and Pierre, and the method of King and Vakakis. The obtained results at this stage using four different methods which are all in time-space domain are compared and it is concluded that all the methods result in a similar answer for the amplitude part of the transverse vibration. At the next step, the nonlinear normal modes are
