A solar fed BLDC motor drive for mixer grinder using a buck converter

In large and small scale applications, different kinds of variable speed driving systems can be found. For saving the energy consumption of these devices, eco-friendly electronics are used, which lead to the development of the Brushless DC motor (BLDC). Its higher power density, higher efficiency, higher torque at low speed, and low maintenance enhances the use of a BLDC motor. The existing mixer grinder consists of the universal motor, which operates in alternating current supply due to high starting torque characteristics and simple controlling of the speed. The absence of brushes and the reduction of noise in the BLDC extends its life and makes it ideal in a mixer grinder. A solar-powered BLDC motor drive for a mixer grinder is presented in this paper. A DC-DC buck converter is utilized to operate the PV (photovoltaic) array at its maximum power. The proposed hysteresis current control BLDC system has been developed in the MATLAB. The commercially available mixer grinder is presented along with the proposed simulated system for performance comparison. It can be concluded that at the no load condition, the efficiency of the experimental existing mixer grinder is 51.03% and simulated proposed system is 81.25% and at load condition, the efficiency of the experimental mixer grinder is 49.32% and simulated system is 79.85%

This study was designed to investigate the attitude of physicians and pharmacists towards generic medicines and thus to reduce the gap between them.Methods: This is a simple, prospective, cross-sectional, comparative study conducted for a period of 3 mo. 100 Subjects (50 pharmacists and 50 physicians) were included in this study. Subjects who ever graduated with the pharmacy degree and working as pharmacists, as well as clinical practitioners, were included in this study. Data collected using a validated questionnaire.Results: 60% of physicians and 80% of pharmacists were confident enough in dispensing generic products. 56% of physicians agree that pharmacists play a vital role in providing assistance on the use of generic medicines. 70% of physicians and 90% of pharmacists agreed that the generic medicines are of less expensive.Conclusion: Our Study concludes that pharmacist's shows a higher positive response towards the usage of generic products than physicians. Generic drugs typically cost 30% to 60% less than their brand products. In addition, patients taking generic drugs seem to be more willing to continue therapy

Comparative pharmaceutical and analytical study of Kasisadi Ghrita prepared by two different methods

Introduction: Sneha Kalpana are the dosage forms which can be used both internally as well as externally. Generally, Sneha Kalpana is prepared by using Agni as source of heating. However, Kasisadi Ghrita is an exception where the sunlight is used as source of heating. This unusual method of preparation looks attractive because of natural heat (sunlight) that is required in the preparation and the yield that may be obtained. The Sneha is heated with volatile drugs in Surya Paka for a specific time so that less heat allows them to leave their active principles in Sneha. The difference between Bhanupaka and Agnipaka is also an area of interest, on this formulation as far as its manufacturing is considered. Kasisadi Ghrita is a herbo-mineral formulation indicated for various skin diseases. Materials and Methods: Kasisadi Ghrita were prepared by classical method of Bhanupaka (KGB) and usual method of Agnipaka (KGA). Both KGB and KGA were analyzed as per the standard protocol. Discussion and Conclusion: Preparation of Kasisadi Ghrita by Agnipaka method is easy as it consumes less time. There were no pharmaceutical constraints in preparation of both samples. Tamra Paatra helps to retain more heat than other vessels during Bhanupaka. The results of the pharmaceutical and analytical study can be considered as the preliminary standards for the preparation of Kasisadi Ghrita

FAIRSECO: An Extensible Framework for Impact Measurement of Research Software

The growing usage of research software in the research community has highlighted the need to recognize and acknowledge the contributions made not only by researchers but also by Research Software Engineers. However, the existing methods for crediting research software and Research Software Engineers have proven to be insufficient. In response, we have developed FAIRSECO, an extensible open source framework with the objective of assessing the impact of research software in research through the evaluation of various factors. The FAIRSECO framework addresses two critical information needs: firstly, it provides potential users of research software with metrics related to software quality and FAIRness. Secondly, the framework provides information for those who wish to measure the success of a project by offering impact data. By exploring the quality and impact of research software, our aim is to ensure that Research Software Engineers receive the recognition they deserve for their valuable contributions.</p

Analysis, Monitoring and Control of Speed Variations for Various Applications of SRM Motor with ESP32 and Thing speak

Due to the growing demand for and growth in the electric vehicle (EV) market in a future civilization with advanced technology. Electric vehicles outperform traditional ones in terms of performance. Because they are environmentally friendly, EVs can help create a green and sustainable environment. They provide convenience with eco-friendliness that conventional cars cannot. Over the past 20 years, the switching reluctance motor (SRM) drive has been created and researched as a revolutionary electrical drive. The brushless switching reluctance motor drive has developed to the point that it may be used in the industrial sector as a reliable, durable, and cost- effective brushless drive with a wide speed range. In this paper, artificial intelligent controllers like Fuzzy Logic Controllers (FLC), and PID are discussed where SRM speed fluctuations are monitored and controlled by a controller using simulation analysis. Experimental analysis is carried out with prototype model. Here various speed variations are controlled and monitored using the ESP32 and Thing Speak cloud platform

Discovery of Major Quantitative Trait Loci and Candidate Genes for Fresh Seed Dormancy in Groundnut

Spanish bunch groundnut varieties occupy most of the cultivated area in Asia and Africa, and these varieties lack required 2-3 weeks of fresh seed dormancy (FSD) hampering kernel quality. Genomic breeding can help to improve commercial groundnut cultivars for FSD in a shorter time with greater precision. In this regard, a recombinant inbred line (RIL) population from the cross ICGV 02266 (non-dormant) &times; ICGV 97045 (dormant) was developed and genotyped with a 5 K mid-density genotyping assay. A linkage map was constructed with 325 SNP loci spanning a total map length of 2335.3 cM and five major QTLs were identified on chromosomes Ah01, Ah11, Ah06, Ah16 and Ah17. Based on differential gene expression using transcriptomic information from dormant (Tifrunner) and non-dormant (ICGV 91114) genotypes, histone deacetylases, histone-lysine N-methyltransferase, cytochrome P450, protein kinases, and ethylene-responsive transcription factor were identified as key regulators involved in the hormonal regulation of dormancy. Six Kompetitive Allele Specific PCR (KASP) markers were successfully validated in the diverse panel including selected RILs of the same population and germplasm lines. These validated KASP markers could facilitate faster breeding of new varieties with desired dormancy using marker-assisted early generation selection

Effectiveness of statins in people living with HIV: a systematic review and meta-analysis of randomized controlled trials

People living with HIV (PLWH) receiving statin therapy have shown improved lipid profiles. However, they are not free from side effects, thereby requiring strict monitoring of the therapy. The meta-analysis aims to analyze the effect of statins in PLWH and critically appraise the effectiveness of statin therapy in PLWH. PubMed, Scopus, and Web of Science servers were used to conduct a systematic search in compliance with the PRISMA guidelines. The meta-analysis of pooled effect estimates is produced using Revman software. A total of 12 RCTs with 8716 participants were included in the analysis. Analysis of the overall effect estimates found that statins resulted in a mean reduction of 41.15 mg/dl (MD = −41.15; 95% CI: −44.19, −38.11; p p p p = 0.0002). When considered collectively, statin therapy’s advantages appear to exceed its occasional predictable side effects like liver or muscle toxicity. PROSPERO registration ID: CRD42023469521.</p
