Thus, the need to search for locally available plant materials is intensified. The objective of this work was to conduct a phytochemical, proximate and Na, K, Ca, Mg, Cu, Zn (minerals) analysis of eucalyptus (Eucalyptus globulus) and gingerbread plum (Noecarya macrophylla) leaves using standard methods and materials of analytical grade. The proximate results revealed moisture of (7.10 ± 09), (7.73 ±0.3) ash (14.76 ± 0.2) (12.85 ± 0.11), crude lipid (1.38± 0.007) (1.46 ±0.02), crude fibre (2.42 ± 0.03) (2.54 ± 0.03), crude protein (5.66 ± 0.04) (7.3 ± 0.006), carbohydrates (68. 68 ± 0.31) (68.12 ± 0.23) for gingerbread plum and eucalyptus respectively. The minerals in gingerbread plum and eucalyptus respectively are as follows; zinc (0.59± 0.06 ppm).4 ± (0.005 ppm), calcium (11.38 ± 0.6 ppm) (19.48 ± 0.53 ppm), potassium (7.21 ± 1.2 ppm) (5.10 ± 0.93 ppm), copper (0.51 ± 0.007 ppm) (0.19 ± 0.04 ppm), magnesium (3.74 ± 0.41 ppm), (10.9 ± 93 ppm), sodium (7.65 ± 0.63 ppm) (12.21 ± 0.32 ppm). Phytochemicals determined include, alkaloids, saponins, tannins, phenols, and phytate. The results have revealed that, the two plants are rich in proximate, phytochemicals and minerals and can be useful for consumption.","PeriodicalId":504704,"journal":{"name":"Asian Journal of Science, Technology, Engineering, and Art","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139177247","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 sheet explains the principles of the electrocardiogram and the interpretation of the waveforms. ECG can be called an electrocardiogram, which is a process of producing electrical activity through repetitive cycles. This diagram shows the voltage and duration of electrical activity by placing electrodes on the skin. Vector cardiography ( VCG) is a procedure that creates a 2D image of the heart's electrical activity by monitoring the spatial location of ECG waves at each successive point in their period. Even in the 21st century, coronary heart disease still represents a serious threat to humans and a major challenge to the scientific community. The most important elements for understanding and interpreting the ECG are the Enthoven triangle and the cardiac vector hypothesis, which have the potential , saving millions of lives when used quickly and appropriately to treat patients.","PeriodicalId":504704,"journal":{"name":"Asian Journal of Science, Technology, Engineering, and Art","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139176941","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}

The features that are related to durability have been evaluated, and they include permeability, resistance to chloride ion penetrations, abrasion, fire resistance efflorescence. Incorporating mineral admixtures in concrete affects various properties. Concrete's permeability decreases and its ability to resist chloride ion penetration rises when admixtures containing a greater alumina content are used. Use of mineral admixtures enhances compressive strength and enhancing abrasion resistance. Moreover, highly reactive mineral admixtures mitigate efflorescence. Notably, while heating PFA concrete improves fire resistance, it reduces overall durability. SF concrete, on the other hand, behaves similarly to standard concrete but can be more brittle. MK concrete exhibits increased strength at 200°C, but its durability and strength decline at higher temperatures compared to other concrete types.RHA pozzolans can replace OPC up to 15% by weight after curing for up to 200 days without lowering the concrete's compressive strength.","PeriodicalId":504704,"journal":{"name":"Asian Journal of Science, Technology, Engineering, and Art","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139289941","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}
