The Concept, Dimensions, And Measurement Of Innovative Competitive Behavior Of Chinese Scientific And Technological Personnel, Rui Li

Double Helix Methodology

Introduction: While competitive behavior in innovation activities is increasingly prevalent in practice and actively promoted by policymakers, it remains an under explored area in academic research. To bridge this gap, we introduce the concept of “innovative competitive behavior,” providing a conceptual definition and clarifying its theoretical boundaries, rooted in social comparison theory from psychology. Methods: A mixed-methods approach was employed to systematically examine this construct. First, a qualitative study guided by grounded theory was conducted to explore the core dimensions of the construct. Subsequently, a quantitative phase involved the development and validation of a psychological scale through questionnaire surveys and …

Journal of Dentomaxillofacial Science

Introduction: Post-extraction bleeding, which is difficult to stop, is rare. However, arterial hemorrhage may lead to a state in which hemostasis is difficult to obtain. We herein report a case in which arterial embolization effectively stopped hemorrhagic bleeding due to mandibular third molar extraction.

Case Report: The patient was a 24-year-old man who suffered from abnormal bleeding during left mandibular third molar extraction (tooth no. 48). As hemostasis via compression with gauze would be difficult, the patient was referred to our department for emergency treatment to stop the bleeding. There was nothing special to note in terms of his vital …

Helical Coil Compression Spring Retrofit Design Of Wheelbarrow For Optimal Load Carrying Effectiveness, Cornelius Ogbodo Anayo Agbo

Makara Journal of Technology

Wheelbarrows are essential multipurpose and dual-function materials handling equipment for many industries and homes. They find exclusive use in the movement of finished goods and raw materials where no other form of transportation works. However, the traditional wheelbarrows require enormous human effort to accomplish the task of conveying a reasonable amount of load from one place to another. During the process, shock loads from road irregularities are transmitted directly to the Barrow pusher. Therefore, this study investigated a retrofitted helical coil, compression spring, wheelbarrow design for effective load transportation. A wheelbarrow with a trapezoidal bucket capacity of 50 l was …

Folia Medica Indonesiana

Amblyopia is defined as a unilateral or bilateral reduction in visual acuity resulting from abnormal binocular interaction during the critical period of visual development. Amblyopia is classified into three etiologies: strabismus, refractive amblyopia, and other vision obstructions. Amblyopia refractive is the most common form resulting from the integration of the retina. Amblyopia is most prevalent in childhood, with a global prevalence of 1.44% mainly in Asia, the United States, and Europe. Early detection and treatment are crucial to ensure proper visual development and prevent long-term vision problems. RGP contact lenses are an alternative treatment method that creates a more effective …

Experimental Analysis Of Droplet Deformation Dynamics In Combined Dc Electric And Shear Flow Fields Using Dpiv, Ayad Ibrahim Khlewee

Al-Esraa University College Journal for Engineering Sciences

This paper presented a systematic study of such droplet deformation at the intersection of uniform DC electric field and hydrodynamic shear flow, in which we focused on conductivity ratio (R) and permittivity ratio (S), describing their influence. The results demonstrate that droplet dynamics is extremely sensitive to the regime: under DC only, either elongation or compression depending on whether R > S or R S, similarly to classical EHD predictions. Under shear-only conditions, deformation was dictated by the balance of elongational stresses (EC) and rotational stresses (RC), with increasing capillary number (Ca) leading to progressive elongation and oscillatory orientation dynamics. When …

Numerical Modeling And Experimental Validation Of A High-Temperature Latent Heat Thermal Energy Storage System Using Metallic Phase Change Materials For Concentrated Solar Power Applications, Fouad Hashim Sharhan

Al-Esraa University College Journal for Engineering Sciences

To ensure reliable performance for the power-block of CSP plants, high power density and near-isothermal discharge must be achieved. A robust means of achieving this is through thermal energy storage (TES). High temperature latent heat storage (LHS) with phase change materials (PCMs) can serve these purposes, however the conventional salts used in PCMs typically suffer from low thermal conductivity that limits power density and increases energy storage charging/discharging times. This manuscript investigates ways to address these limitations using high temperature metallic phase change materials (MPCMs) while also developing a validated numerical framework to aid in their design. To this end, …
