A dual coil induction heating machine for jewelry factories developed by electromagnetic analysis

Abstract

Induction Heating Machine (IHM) is a crucial device in the jewelry industry, utilizing electromagnetic fields to generate heat and join precious metals. This research focuses on developing a Dual Coil Induction Heating Machine (Dual Coil IHM) to enhance production efficiency and reduce costs in jewelry factories using Electromagnetic Analysis (EMA) through Ansys Maxwell software. The research process began with testing a single-coil IHM under real operating conditions and using EMA to analyze the generated magnetic flux density (B). Subsequently, dual-coil configurations in Parallel and Series arrangements were designed and compared. The experimental results revealed that the series dual coil produced a higher magnetic flux and allowed for optimizing current (I), frequency (f), number of coil turns (N), and coil spacing (d) for better manufacturing performance. The findings indicate that the series dual-coil IHM can double production capacity compared to the conventional single-coil model. Furthermore, EMA technology minimizes physical testing, reduces errors, and enhances precision in designing industrial machinery for the jewelry manufacturing sector.

Detection of salivary biomarker  for migraine diagnosis

Detection of salivary biomarker for migraine diagnosis

Migraine, a prevalent neurological disorder, is the third most common disease globally, causing significant health and financial burdens. It has four stages: prodrome, aura, headache, and postdrome. The prodrome (also known as premonitory) stage is crucial as it precedes the headache by up to 72 hours. Taking medication during the premonitory peroid has shown to prevent the headache phase . However, the symptoms of premonitory period lack specificity, making it difficult for patients to know if they’re experiencing premonitory symptoms. Calcitonin-gene related peptide (cGRP),is a protein that plays a key role in migraine pathogenesis and studies found that salivary cGRP levels increase during the premonitory stage. This study aims to develop and evaluate a lateral flow immunoassay kit for detecting salivary cGRP levels in migraine patients during the prodrome stage. It can serve as a confirmation tool for premonitory symptoms.
