Investigation Of Fiber Length Change In Different Stages Of Ring Spinning Process

Fiber length is one of the major fiber properties that influence yarn strength, evenness, product handle, product luster, and yarn hairiness. To assure yarn quality, fiber passes through a number of machinery during the spinning process, where it is subjected to various sorts of action that modifies the fiber length. As different process parameters are chosen based on fiber length, fiber length analysis throughout the spinning process will benefit in the adjustment of machine parameters to produce better quality yarn. This study will reveal the chronological change in average fiber length at different stages of the carded ring spinning process, as well as a correlation analysis of length change among different phases, using correlation and regression methods. For five distinct mixing samples, raw cotton, card mat, carded sliver, breaker drawn sliver, finisher drawn sliver, roving, and yarn (pneumafil) were examined at each stage from raw cotton to ring frame. Then, using USTER AFIS PRO, all of the samples were numerically evaluated and statistically analyzed using Microsoft Excel 2016. A positive correlation between fiber length changes at several phases was observed in the experiment, with average fiber length increasing in carding, breaker drawing, finisher drawing, and simplex but decreasing in card mat and ring.

Investigating the Revival of Ancient Egyptian Artifacts as a Symbol of Power through their Occupation of European Public Spaces: A Chrono-Morphological Study

Numerous architectural styles have been explored in recent years (Pakkanen 2018). However, Egyptian revival did not obtain the consideration it deserved till lately, when there was a remarkable flow of attention coursed by various significant ancient Egyptian exhibitions all over the world, which led to the publications of books and articles tackling the Egyptian revival (Curl 2013). In this paper the researcher will try to investigate the chronological change of form and shape of ancient Egyptian architectural features that were revived in European public spaces to signify power, sovereignty, and authority. Curl (2013) charts the argument of the persistence of Egyptian motifs in design from Greco-Roman Antiquity, through the Mediaeval, Baroque, and Neo-Classical periods. Our hypothesis is that Ancient Egypt is a central source, rather than peripheral, to the development of considerable volume of European urbanistic and architectural features. We will distinguish manifestations with Egyptian connotations based on literature reviewed, field observation and the methodology of Curl (2013). Aiming only on three ancient Egyptian sources, the Sphinx, the obelisk, and the temple. Keywords: Egyptian revival, Ancient Egyptian artifacts, morphological regeneration, space occupation, public spaces

Comparison of the clinical performance and usefulness of five SARS-CoV-2 antibody tests

We examined the usefulness of five COVID-19 antibody detection tests using 114 serum samples at various time points from 34 Japanese COVID-19 patients. We examined Elecsys Anti-SARS-CoV-2 from Roche, and four immunochromatography tests from Hangzhou Laihe Biotech, Artron Laboratories, Chil, and Nadal. In the first week after onset, Elecsys had 40% positivity in Group S (severe cases) but was negative in Group M (mild-moderate cases). The immunochromatography kits showed 40–60% and 0–8% positivity in Groups S and M, respectively. In the second week, Elecsys showed 75% and 50% positivity, and the immunochromatography tests showed 5–80% and 50–75% positivity in Groups S and M, respectively. After the third week, Elecsys showed 100% positivity in both groups. The immunochromatography kits showed 100% positivity in Group S. In Group M, positivity decreased to 50% for Chil and 75–89% for Artron and Lyher. Elecsys and immunochromatography kits had 91–100% specificity. Elecsys had comparable chronological change of cut-off index values in the two groups from the second week to the sixth week. The current SARS-CoV-2 antibody detection tests do not provide meaningful interpretation of severity and infection status. Its use might be limited to short-term epidemiological studies.

Harry Potter and the Orthodox community: еxperience in content analysis

В статье анализируется хронологическое изменение палитры мнений духовенства и мирян российской части Русской Православной Церкви по отношению к произведениям Дж. Роулинг (цикл романов о Гарри Поттере) и молодежным субкультурам, появившимся на их основе в 2002–2020 гг. В качестве источников исследования выступают высказывания православного духовенства в религиозных и светских средствах массовой информации, интервью авторов со священнослужителями, сотрудниками церковной администрации, преподавателями Православного Свято-Тихоновского гуманитарного университета (ПСТГУ), выпускниками и учащимися православных гимназий и воскресных школ. The article analyzes the chronological change in the palette of opinions of the clergy and laity of the Russian part of the Russian Orthodox Church in relation to the works of J.K. Rowling (a cycle of novels about Harry Potter) and the youth subcultures that emerged on their basis in 2002–2020.

One hundred million years history of bornavirus infections hidden in vertebrate genomes

Although viruses have threatened our ancestors for millions of years, prehistoric epidemics of viruses are largely unknown. Endogenous bornavirus-like elements (EBLs) are ancient viral sequences that have been integrated into animal genomes. These elements can be used as molecular fossil records to trace past bornaviral infections. In this study, we systematically identified EBLs in vertebrate genomes and revealed the history of bornavirus infections over nearly 100 million years. We found that ancient bornaviral infections have occurred in diverse vertebrate lineages, especially in primate ancestors. Phylogenetic analyses indicated that primate ancestors had been infected with various bornaviral lineages during evolution. Moreover, EBLs in primate genomes formed clades according to their integration ages, suggesting that epidemic lineages of bornaviruses had changed chronologically. However, we found that some bornaviral lineages coexisted with primate ancestors and underwent repeated endogenizations for tens of millions of years. Furthermore, this viral lineage that coexisted with primate ancestors was also endogenized in some ancestral bats. Notably, the geographic distributions of these bat ancestors have been reported to overlap with the migration route of primate ancestors, suggesting that long-term virus-host coexistence could have expanded the geographic distributions of the viral lineage and might have spread their infections to new hosts. Thus, our findings describe hidden virus-host co-evolutionary history over geological timescales, including chronological change in epidemic bornaviral lineages, long-term virus-host coexistence, and expansion of viral infections.

Analyzing the roles of newspaper articles and tweets to help alleviate sudden physician absenteeism: case study of Takano Hospital in Fukushima in the long-term aftermath of the 2011 Japan’s triple disaster (Preprint)

BACKGROUND Rural physician undersupply is a universal concern, leading to sudden physician absenteeism or unavailability on occasion. While media and social networking services may help mitigate these emergencies, information is lacking about their actual contribution in times of physician absenteeism. On December 30, 2016, the director and sole physician of Takano Hospital in Fukushima, Japan, died. The physician’s passing placed many hospitalized patients in danger. This sudden case of physician unavailability, named the Takano Hospital Crisis, provoked massive attention from the general public, in the media and on social media networks such as Twitter. OBJECTIVE The aim of this study was to analyze newspaper articles, tweets and Twitter accounts relating to Takano Hospital Crisis. METHODS Newspaper articles and tweets were searched for keywords associated with Takano Hospital Crisis and its former director between October 2016 and June 2017. We first evaluated the chronological change in the number of articles and tweets, and the number of characters and relevant keywords in the articles. Then tweets and influencers who were popular on the Twitter platform from December 30, 2016 to February 28, 2017, were categorized. RESULTS We assessed 151 newspaper articles and 67,006 tweets. The results show that number of newspaper articles and tweets steeply increased and then diminished within the first month of the incident. The median number of characters in newspapers articles was 436 and the most frequent keyword was medical doctor. There were 753 original tweets that were retweeted more than four times from December 30, 2016 to February 28, 2017. Of these, 245 (32.5%) expressed concern. Notable influencers were journalists, news media outlets, and healthcare professionals that helped with fund raising and providing clinical service in the hospital. CONCLUSIONS Twitter could temporarily function in cases of sudden physician absenteeism to attract volunteers and funding, however, this would not be a long-term solution. In a more general context, a long-term effort of supports from the hospitals themselves and the government will be required to manage the persistent state of physician absenteeism.
