In addition, the process parameters like punch crosshead, deformation temperature, surface roughness of both punch head and sheet blank, lubricant state, and the value of the applied load. Friction in the actual contact area plays a significant effect in obtaining a high-quality part and reducing the production cost. The study provides a new idea to specify the suitable Coefficient of Friction (COF) used when forming Aluminium AA1060, taken according to Coulomb’s Friction Law and Stribeck Diagram for different lubricant states. The methodology of this research is based on the finite element analysis using ABAQUS/CAE 2020 of the Nakajima Formability Test for different Coefficients of Friction (COF) that are taken from Stribeck’s Diagram according to sheet material type, where the suitable Coefficient of Friction (COF) that achieves ISO 12004-2 condition to consider the sheet material successful in the test and valid for use in the manufacturing process. Results show that the Coefficient of Friction (COF) significantly affects the Formability behaviour and specifies the Location of Tearing (crack), where at higher (COF), the Formability of Aluminium AA1060 is decreased. The Tearing (crack) occurs near the circumference of the sample. Consequently, the sample was considered failed in the test and invalid to use in manufacturing processes. At the same time, when (COF) is low, the Formability of the sheet material increases, and tearing occur near the centre of the sample apex, so the sample is considered successful in the test and valid to use in the manufacturing process according to ISO 12004-2.","PeriodicalId":270620,"journal":{"name":"Salud, Ciencia y Tecnología - Serie de Conferencias","volume":"38 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141356839","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}

Factors such as women's limited access to education, societal perceptions of women in sports, self-esteem, self-confidence, menstruation abnormalities, self-image or body image, gender role orientation, and competitiveness should all be taken into account. Yoga is sometimes seen as not being a sport, although it is really a physical exercise that follows rules, can be done competitively, and has measurable outcomes. Multiple reasons contribute to the low engagement of women in sports throughout society. Family has a profound impact, often initiating early engagement in sports, although this differs according to gender. Female participation in sports is often seen unfavorably. Societal attitudes and biases are another factor that impacts sports participation. For instance, many girls refrain from engaging in certain hobbies out of concern that they would be seen as masculine. This is because societal attitudes and biases about sexuality hinder females from participating. Female athletes possess psychological traits that include gender role orientation in several sports, including wrestling, weight lifting, and bodybuilding. These activities have traditionally been deemed unsuitable for women due to the possible adverse consequences of masculinization. Intensive training contributes to the improvement of self-esteem, self-image, and body image. Engaging in athletic activities also aids in the promotion of positive body image. It enhances body contour and promotes a harmonious physique, thereby enhancing self-perception. Yoga enhances strength, flexibility, and balance, all of which are vital for athletes. The majority of yoga postures are essential for enhancing strength, improving the range of motion, mobility, and coordination in athletic performance, as well as preventing injuries.","PeriodicalId":270620,"journal":{"name":"Salud, Ciencia y Tecnología - Serie de Conferencias","volume":"28 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141357225","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 specificity of the requisite angle for each site is underscored, contingent upon the solar trajectory over daily, monthly, and annual cycles. The determination of this optimal angle is imperative for maximizing the yield from solar PV systems within the confines of Iraq. Worldwide locales have seen the application of varied methodologies for ascertaining the correct tilt angle. The efficacy of PV systems is observed to be significantly influenced by whether a fixed or a tracking system is employed to modulate the tilt angle. The present manuscript delineates the contemporary state of research and praxis pertaining to the influence of tilt angle on PV output, employing an array of optimization techniques. Furthermore, the work offers a disquisition on the determination of the most advantageous tilt angle to optimize energy acquisition in Iraq. The inquiry reveals that an optimal tilt angle for Iraq is discerned to be 38.3. This compendium is intended to augment the compendium of knowledge available to designers and scholars endeavoring to pinpoint the most favorable tilt angle for solar PV systems in any given Iraqi locale.","PeriodicalId":270620,"journal":{"name":"Salud, Ciencia y Tecnología - Serie de Conferencias","volume":"7 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141360741","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 field of corn is divided into three sectors (R1: non-magnetized river water, R2: magnetized river water with 1000 gauss, R3: magnetized river water with 3000 gauss. Examinations are made on the physical and chemical properties of the irrigation water, EC, PH, anions and cations for both water and soil as well as the productivity of the corn plant. The results indicate that the magnetization of irrigation water with an intensity of 1000 gauss (R2) had a positive effect on all properties of soil, water and moisture content in addition to productivity. Where the value of total dissolved salts (TDS), EC, and the values of K, Na, Mg, and Ca ions decreased for irrigation water. While the PH value of irrigation water increased at R2, this increase in pH may be due to the formation of more bicarbonate, calcium and hydroxide ions, which reduce acidity. With stability the value of these characteristics at the intensity of 3000 gauss (R3), the matter which indicates that this intensity is not useful for improving water properties. An increase in the value of (N, B, K) was observed in both leaves and seeds of corn when magnetized at an intensity of 1000 gauss. The magnetization of irrigation water at an intensity of 1000 gauss increases the yield of corn plant more than the magnetized 3000 gauss.","PeriodicalId":270620,"journal":{"name":"Salud, Ciencia y Tecnología - Serie de Conferencias","volume":"85 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141359589","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}

A study was conducted to examine the effectiveness of five types of radiation shielding sheets composed of a blend of microlead and chlorophyll at varying concentrations (50, 100, 150, 200, and 250 wt% with 35 wt%, respectively) with biosilicon as a base. A comparison was made between the transmission dosages of these sheets and a lead standard (commercial shield). The tensile strength was tested when radiation shielding sheets were being made and used the European Standard for Industry test method (IEC 61331-3:2014) for X-ray protection equipment to measure the transmission dosage. and compare the results with radiation transmitted through a lead standard that had different thicknesses (0.05, 0.1, 0.15, 0.2, 0.25, 0.3, and 0.35 mm). These measurements were taken at tube voltages of 30, 60, 90, 120, 150, and 180 kVp. In the results, it was found that using a mixture of 150% microlead and 35% chlorophyll worked to measure a dose similar to 0.3 mm of lead. The transmission dose was 13.58 mR and 13.8 mR for sheet lead, and the density of the shield is 1.72 g/cm3. For this reason, it could be used instead of lead sheets, making it a good choice for protecting medical equipment from radiation.","PeriodicalId":270620,"journal":{"name":"Salud, Ciencia y Tecnología - Serie de Conferencias","volume":" 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141366381","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}

It is known, that these mixtures have a very low initial strength, requiring longer curing times and more susceptibility to moisture damage. Geopolymer is often used in the fields of concrete and soil improvement performance. It has not been used in the field of asphalt mixtures; so, this study can be considered as the first time of using it. This study tried to make a new CBEM by incorporating the Geopolymer into the mix to improve its initial performance and enhance early strength. Geopolymer was created inside CBEM by activating the fly ash using an alkali solution. Three percentages of fly ash (1, 3, and 5%) were used for creating Geopolymer; and different curing periods (3, 7, and 14 days) were also used. Marshall stability and Indirect Tensile Strength tests were conducted to assess the mechanical properties of mixtures. The results showed that Geopolymer can be a promising material for creating cold mixes with a better initial strength compared to traditional cold mixes. Comparing CBEMs with (5% FA + 0% CF) to control CBEMs, the increase with MS was approximately (32% at 3 days, 43% at 7 days, and 37% at 14 days). The performance of cold mixes was enhanced by the addition of Geopolymer with different FA contents and curing times when compared to control CBEMs. This improvement was particularly noticeable at longer curing times and higher fly ash contents.","PeriodicalId":270620,"journal":{"name":"Salud, Ciencia y Tecnología - Serie de Conferencias","volume":"114 50","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141360852","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}
