The study encompasses the establishment of a specialized measurement bench for impulse mode electrical tests, involving the adaptation of the signal generator with an adjustable supercapacitor and variable inductance. For precise measurements, a carefully designed filtering system prevents voltage overshoots. Given the critical sensitivity of voltage and frequency measurements for passive components in RF and high-voltage applications, the methodology is further refined to achieve optimal compromises across various parameters. The primary objective remains the determination of the voltage across the evaluated capacitor using the proportionality coefficient 𝛼, essential for accurate trimmer characterizations. In this paper, useful insights are provided into the electrical characterization of trimmers, as well as a refined methodology designed for RF and high-voltage applications. The findings presented herein enhance our understanding of trimmer behavior, offering potential implications for improved component selection and performance in a range of electrical systems.","PeriodicalId":482617,"journal":{"name":"Advances in bioengineering and biomedical science research","volume":"50 12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140457860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This peptide is composed of 14 amino acid residues, (INWKKMAATALKMI) and mostly resides in the venom of the Polistes wasp. It has a molecular weight of 1619.00KDa. Parapolybia-MP is a group of mast cell degranulating peptides possessing various activities such as anticancer, anti-inflammatory, and cytolytic properties. This peptide being a tetra deca-peptide is linear in configuration and, modifies itself into a cyclic one upon binding to the plasma membrane of the microbes. Diabetes foot ulcer is the leading cause of the lower leg amputation. Mainly 15% of patients with diabetes develop foot ulcers. Microbial species at the wound site tend to cause low wound healing capacity. To focus on this issue, a peptide with good anti-diabetic and hemolytic activity is required. Parapolybia-MP was found to have good anti-diabetic activity with an IC50 value of 70.31%. It also has negligible hemolytic activity as well.","PeriodicalId":482617,"journal":{"name":"Advances in bioengineering and biomedical science research","volume":"39 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140458367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many electronic applications utilize capacitors, and understanding the phenomena around their edges is crucial to their design and optimization. Our research explores in detail the distribution of electric fields and electric potential near electrodes using models and methods based on Maxwell's principles and Gauss's theorem. Divergent electric fields can create edge effects, which affect capacitor performance by creating edge effects. A circular electrode shape is one of the strategies we present to mitigate these effects. The implications of these findings in the field of electronics and related technologies are discussed in the final section.","PeriodicalId":482617,"journal":{"name":"Advances in bioengineering and biomedical science research","volume":"178 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140485210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
