{"title":"Estimate of Temperature Rise in the 21st Century for Various Scenarios","authors":"Rapp Donald","doi":"10.61927/igmin218","DOIUrl":"https://doi.org/10.61927/igmin218","url":null,"abstract":"The International Panel on Climate Change (IPCC) published a lengthy report on climate change in early 2023. This report hypothesizes five potential scenarios of greenhouse gas emissions from 2015 to the end of the century (2100) and estimates the global average temperature gain in the year 2100 from the mid-1800s for each scenario. The method of calculation in the IPCC report is obscure. The results are merely stated. The present paper provides a clear method for estimating the temperature gain each year from 2015 until 2100, along with yearly estimates of ppm of CO2. To facilitate the calculations, a set of scenarios of future emissions was chosen that is analogous to the scenarios used by the IPCC but is more amenable to computation. The basic assumption in this paper is that most of the temperature gain from the mid-1800s to 2015 (1.15 C – as reported by the IPCC) was due to rising CO2 concentration in the atmosphere and a relationship is thereby derived between warming and gigatons of CO2 emitted for the period: 1800s to 2015. If it is assumed that the amount of warming per gigaton CO2 from the past persists into the 21st century, then future warming in the 21st century can be estimated for any assumed future scenario of CO2 emissions. This paper provides a simple and clear estimate of yearly CO2 ppm and temperature rise from 2015 to 2100 since the 1800s for a set of scenarios that cover the likely range of future emissions.","PeriodicalId":509147,"journal":{"name":"IgMin Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141834693","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 study explores the genetic information and phytochemicals of the species native to Gia Lai province, Vietnam before its conservation and cultivation. Five species of A. racemosus were analyzed using the trnL-e/trnL-f regions sequence. A. racemosus roots were extracted by water then Ultra-High-Performance Liquid Chromatography coupled with Quadrupole/Time-Of-Flight Mass Spectrometry (UHPLC-Q-TOF-MS) spectroscopy was used to screen for their phytochemicals. We have confirmed the DNA genetics of A. racemosus species collected in Gia Lai, Vietnam. In water extract of A. racemosus roots, UHPLC-Q-TOF-MS tentatively identified two flavonoids (Quercetin-3-glucuronide, Rutin), five steroidal saponins (Shatavarin I, Shatavarin IV, Shatavarin IX, Asparacoside, Asparanin A), and two steroids (β-sitosterol, Daucosterol). The experimental findings confirm the A. racemosus species for conservation and cultivation in Vietnam and contribute the benefits to the chemical literature of Vietnamese natural flora. A. racemosus should be further studied for pharmaceutical activities.","PeriodicalId":509147,"journal":{"name":"IgMin Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141835172","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 3-D objects considered for the multi-class (four-class) classification task are ‘triangle-square’, ‘circle-square’, ‘square-triangle’, and ‘triangle-circle’. The 3-D object ‘triangle-square’ is considered for Class-1 and the remaining 3-D objects ‘circle-square’, ‘square-circle’, and ‘triangle-circle’ are considered for Class-2, Class-3, and Class-4. The digital holograms of 3-D objects were created using the two-step Phase-Shifting Digital Holography (PSDH) technique and were computationally post-processed to obtain phase-only digital holographic data. Subsequently, a deep CNN was trained on a phase-only image dataset consisting of 2880 images to produce the results. The loss and accuracy curves are presented to validate the performance of the model. Additionally, the results are validated using metrics such as the confusion matrix, classification report, Receiver Operating Characteristic (ROC) curve, and precision-recall curve.","PeriodicalId":509147,"journal":{"name":"IgMin Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141665864","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}

{"title":"Physical Activity and Lifestyle of Female Students of the Faculty of Health Sciences University of Applied Sciences in Tarnów (Poland)","authors":"Schab Karolina, Żarów Ryszard","doi":"10.61927/igmin213","DOIUrl":"https://doi.org/10.61927/igmin213","url":null,"abstract":"Introduction: Physical activity is a natural need of every human being, brings significant health benefits, and adapts the body to exertion. Lifestyle is based on conscious choices that affect health. Health-promoting activities such as regular physical activity, healthy and wholesome meals, adequate recovery, and stress reduction in daily life minimize the risk of future behavior. The purpose of this study was to evaluate the Physical Activity (PA) and lifestyle of female students of the Faculty of Health Sciences (FHS) at the Tarnow University of Applied Sciences surveyed in February and March 2023. Among other things, the time, frequency, and places of physical activity were investigated, and did the physical activity and lifestyle of female students differ according to the field of study undertaken and between first- and fourth-year physiotherapy students? Methods: The survey was conducted among 167 female students of physiotherapy, physical education, nursing, and cosmetology at the FHS. Using a diagnostic survey, a questionnaire survey was conducted, the research tool was a survey questionnaire of our design, which included questions on physical activity, lifestyle, and sociodemographic data. Results: The results indicate that the female students led active and healthy lifestyles. The vast majority, more than 90%, of the female students surveyed were aware of how physical fitness and their health-promoting activities, as well as knowledge related to these issues, would be important in their future profession. Regarding the field of study and the physical activity undertaken, a statistically significant difference (p < 0.05) was shown, it was the female students from physical education who were the most active among all women. Conclusion: It can be concluded that the chosen field of study influences the declared health-promoting behavior of female students and that the physical activity undertaken and the healthy lifestyle are related to the choice of future profession, while the field of study and the year of the study did not differentiate the lifestyle of female students.","PeriodicalId":509147,"journal":{"name":"IgMin Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141671852","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}

These equipment play a climacteric role in variegated business administration and buildings by providing heat exchange between two fluids. However, over time, exchangers can be subject to variegated problems such as contamination and sediment build-up. This can diminish heat transfer efficiency, leading to energy waste and equipment malfunctions. Calcification is a problem that comes off when water becomes saturated with hard minerals and exceeds the solubility of these minerals. These minerals precipitate as a consequence of water evaporation or chemical reactions and form a solid layer called limestone. Limescale can bring variegated problems in homes, business administration, and water transportation systems. Lime accumulates on heat transfer superficies, reducing the superficies area of ​​these superficies. This reduces the superficies area available for heat transfer and inhibits heat transfer. The thermal conductivity of lime is lower than water. Scale, which is the formation of a scale layer on heat transfer superficies, reduces the thermal conductivity of these superficies and prevents heat transfer. This study focuses on the types of contamination in heat exchangers, the effect of contamination on heat transfer and other factors, and methods of clogging.","PeriodicalId":509147,"journal":{"name":"IgMin Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141680977","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}
