Beauty in the Indigenous Pageant The Cultural and Social Relevance of Miss Samoa
This paper investigates the Miss Samoa pageant’s historical origins, cultural relevance and preservation, the ways in which it empowers women, the public’s perspective, and future development. Secondary sources on the pageant were limited to eight pieces, so interviews with judges, contestants, winners, and participants were sources of information. Sixty surveys were also conducted to gain the public’s perspective of the pageant. The study found Miss Samoa is more popular for its entertainment value than cultural relevance. The Miss Samoa pageant has been utilized as an agent of empowerment for individual women but is not necessarily influential on a larger social scale. The results also suggest the pageant been blended into Samoa as more of an indigenous pageant than a beauty pageant. The pageant’s capabilities are limited due to the boundaries imposed by tourism-driven motivations. In order to encourage future development, the Miss Samoa pageant would need to prioritize locality as the paramount focus
Plastic Deformation of Bicrystals composed of <100>, <111>, and Single Glide Oriented Aluminum Crystals
When two crystal grains having large different deformation-modes are adjacent to each other, their compatibility at the boundary plane becomes extremely confused. Therefore, it is thought that such a grain boundary condition plays an important role on several phenomena of the materials containing it. In this study, three kinds of bicrystals composed of two crystals within three kinds of single crystals (a common single crystal for single glide, a single crystal with tensile orientation and a single crystal with tensile orientation), are prepared and tested by tension. The additional slips on {110} are activated, and the boundary strength is positive in the bicrystals composed of a crystal for single glide and a crystal with tensile orientation. In the bicrystals composed of a crystal for single glide and a crystal with tensile orientation, a few clustered slips occur from the grain boundary in the grain with tensile orientation. The boundary strength is negative. Some micro-cracks are observed along the grain boundary of bicrystals composed of a crystal with tensile orientation and a crystal with tensile orientation. The boundary strength is found to be zero
Comparative accuracy of cervical cancer screening strategies in healthy asymptomatic women:a systematic review and network meta-analysis
To compare all available accuracy data on screening strategies for identifying cervical intraepithelial neoplasia grade ≥ 2 in healthy asymptomatic women, we performed a systematic review and network meta-analysis. MEDLINE and EMBASE were searched up to October 2020 for paired-design studies of cytology and testing for high-risk genotypes of human papillomavirus (hrHPV). The methods used included a duplicate assessment of eligibility, double extraction of quantitative data, validity assessment, random-effects network meta-analysis of test accuracy, and GRADE rating. Twenty-seven prospective studies (185,269 subjects) were included. The combination of cytology (atypical squamous cells of undetermined significance or higher grades) and hrHPV testing (excepting genotyping for HPV 16 or 18 [HPV16/18]) with the either-positive criterion (OR rule) was the most sensitive/least specific, whereas the same combination with the both-positive criterion (AND rule) was the most specific/least sensitive. Compared with standalone cytology, non-HPV16/18 hrHPV assays were more sensitive/less specific. Two algorithms proposed for primary cytological testing or primary hrHPV testing were ranked in the middle as more sensitive/less specific than standalone cytology and the AND rule combinations but more specific/less sensitive than standalone hrHPV testing and the OR rule combination. Further research is needed to assess these results in population-relevant outcomes at the program level
Detection of deletion and mutation on pig Mx1 gene (gene resistance to influenza virus) with PCR-RFLP Nar I restriction
The study was done to detect the incident of deletion and mutation in exon 14th of Mx1 gene in pig. Six hundred base pairs at the position (1937 to 2537) of the 14th exon of the pig Mx1 gene was amplified by polymerase chain reaction (PCR) from 15 breed of pig DNA sample. The amplified PCR products were digested by Nar I enzyme that called restriction fragment length polymorphism (PCR-RFLP) technique. The results show genetic polymorphism at the 14th exon of pig Mx1 gene. The Nar I digested revealed three phenotyphic variation (C/C, C/N and N/N, designated for Nar I cut homozygote, heterozygote and for Nar I no cut homozygote, respectively). The Nar I (N/N or C/N) type is corresponding to (1) the deletion 11 bp at the position 2064 to 2075. This type was observed in Landrace breed. (2) the incidence of two point mutation at the position 2065 Guanine (G) change to Thymine (T) and at the position 2124 Guanine (G) change to Adenine (A).This type was observed in Chinese native pig (Meishan) and Vietnamese native pig. Key words: Deletion, mutation, pig Mx1 gene and PCR-RFL
Plastic Deformation of <111> Oriented Aluminum Single Crystals
It is known that an aluminum single crystal having tensile orientation shows an initial rapid hardening, and that its flow stress increases gradually until failure. However, many problems pertaining to the deformation mechanism of the oriented single crystal remain unsolved. In the present study, to clarify the deformation mode of aluminum single crystals having multiple slip orientations, tensile test were performed at various temperatures on oriented single crystals. At room temperature, the oriented single crystal deformed only by fine multiple slips, and the flow stress increased with an increase of strain until failure. On the other hand, the coarse wavy slips composed of {111} and {100} slips occurred at high temperatures, such as 473K. In the single crystal having a tensile orientation deviated from by a few degrees, the clustered slips were observed in addition to the fine multiple slips. It is concluded that the deformation mode and flow stress of the single crystal are very sensitive to the tensile oriention in the vicinity of
Effect of Deformation Temperature on the Stage IV Deformation in <100> Oriented Aluminum Single Crystal
It is known that at room temperature the tensile stress-strain curve of an aluminum single having tensile orientation becomes flat after about a two percent elongation. (This flat region of the stress-strain curve is named Stage IV). In the previous paper, the propagation of a clustered slip accompanied by a prominent cross slip was observed in the Stage IV region of curve. In the present study, oriented aluminum single crystals were tested in tension at various temperatures so as to clarify the influence of temperature on the deformation mechanisms in Stage IV. At 203K, a few clustered slip lines accompanied by a prominent cross slip occurred, but they did not propagate in the entire region of the specimen. The stress-strain curve became flat only from about a ten percent elongation. In the crystal stretched at 77K, the cluster did not propagate at all from either end of the specimen, and so the stress-strain curve did not become flat. On the other hand, a wavy coarse slip was observed and the curve became flat from about a 0.5 percent elongation at 473K. It was suggested that these wavy slip lines were produced by a frequent repetition of the cross slip on two {111} planes and also possidly on a {110} plane having the same slip direction. It was confirmed that the occurrence of Stage IV is caused by the of the clustered slip accompanied by a prominent cross slip, and is much influenced by the temperature of deformation due to the easiness of the cross slip
Effect of Grain Boundary on Pseudo-elastic Deformation of Cu-Zn-Si Bicrystal of Shape Memory Alloy
Two sorts of Cu-Zn-Si pseudo-elastic bicrystals of shape memory alloy were tested in tension to know the effects of the grain boundary. The remaining martensites were observed in the vicinity of the grain boundary, and the propriety of analyses through use of m/m。 and Nᵢj values and of the compatibility of the plastic strain were studied. The variant of martensite occurring primarily in each grain during deformation, can be predicted with use of them value (shear factor of the variant) in general. The analyses through use of m/mᵢ and Nᵢj values and the equations of the plastic strain compatibility are sufficiently useful to know the variant of martensite nucleated additionally in the vicinity of the grain boundary. However, the possibility of activation of slip must be considered in this case. The reversible strain of the isoaxial bicrystal is larger than that of the non-isoaxial bicrystal. However, the relation between the reversible strain and the misorientation of bicrystal is not yet sufficiently known
