The world data on R and [Formula: see text] is used to derive a value of the QCD scale parameter, free of hadronization and renormalization scale uncertainties, of [Formula: see text]. This value is then used to investigate the convergence of the QCD perturbation expansions for several different jet topology measures, with the choice [Formula: see text] of the renormalization scale. In most cases satisfactory convergence is observed. The overall consistency of all measurements of [Formula: see text] is also discussed. Although [Formula: see text] seems high, present data is consistent (17% C.L.) with a global world average value of [Formula: see text], [Formula: see text].

AbstractSARS-CoV-2 emerged in late 2019 and has since spread around the world, causing a pandemic of the respiratory disease COVID-19. Detecting antibodies against the virus is an essential tool for tracking infections and developing vaccines. Such tests, primarily utilizing the enzyme-linked immunosorbent assay (ELISA) principle, can be either qualitative (reporting positive/negative results) or quantitative (reporting a value representing the quantity of specific antibodies). Quantitation is vital for determining stability or decline of antibody titers in convalescence, efficacy of different vaccination regimens, and detection of asymptomatic infections. Quantitation typically requires two-step ELISA testing, in which samples are first screened in a qualitative assay and positive samples are subsequently analyzed as a dilution series. To overcome the throughput limitations of this approach, we developed a simpler and faster system that is highly automatable and achieves quantitation in a single-dilution screening format with sensitivity and specificity comparable to those of ELISA.

Background: According to 2018 World Health Organization (WHO) data globally, an estimated 17.3% of the population has inadequate zinc intake, with estimates ranging from 5.7% in Oceania to 7.6% in Europe, 9.6% in America and the Caribbean, highest in Africa (23.9%) and Asia (19.6%). Zinc is important for the function of a number of enzymes and growth hormones during pregnancy. In pregnant women, the relative zinc concentration decreases up to 35% due to the influence of hormonal changes and the transport of nutrients from mother to baby. Objectives: The purpose of this study was to identify the effect of giving zinc tablets to pregnant women with zinc deficiency in the third trimester on body weight and length of babies born at the Makassar City Health Center. Methods: This type of research is True Experimental with a pretest-posttest design with a control group. The sample in this study was 62 samples of third trimester pregnant women, and the sampling technique used was purposive sampling. Measurement of zinc levels in third trimester pregnant women using the Elisa reader kit at the Research Laboratory of the Hasanuddin University Teaching Hospital. The research instruments were in the form of a research explanation sheet, respondent's consent sheet, respondent's checklist sheet, and the mother's zinc tablet consumption control sheet for 14 days. Results: Judging from the average value of newborns in pregnant women who did not have zinc deficiency, the average value of birth weight in pregnant women with zinc deficiency was 15.70 g/dL and 18.95 g/dL. zinc deficiency with a value (p < 0.05), while pregnant women with zinc deficiency have an average birth length of 10.00 g/dL and mothers who do not have a deficiency of 19.87 g/dL with a value (p < 0.05). So, it can be concluded that giving zinc tablets to pregnant women in the third trimester has an effect on Birth Weight (BBL) and Birth Length (PBL). Conclusion: Giving zinc tablets has an effect on increasing zinc levels in third trimester zinc deficiency pregnant women and increasing birth weight and length of the baby.

The emergence of a new virus in the global world at the end of 2019, namely Corona Virus Disease 2019, brought tremendous excitement to all inhabitants of the earth. The emergence of this virus brings tremendous concern and fear to the world because the spread of this virus is quite fast, even the most frightening is that the risk of death of people exposed to this virus is very large. Indonesia itself, cannot avoid the impact of this Covid-19 case. As a form of efforts to prevent and minimize transmission of the virus, the Indonesian government has issued a social distancing / physical distancing recommendation. This situation also causes the interaction between communities to be very limited. This situation seems to be able to eliminate hospitality among the community. This paper aims to emphasize the importance of maintaining the value of Christian hospitality in society amid the Covid-19 pandemic.

The “idea of human” (“type of attitude to the world”) is considered as a relevant category of the conceptual apparatus of the modern science of literature. The aim of the work is to analyze the theoretical and methodological potential of this category on the basis of large typological units of the literary process, marked with the concepts of “historical and literary era”, “artistic and cognitive cycle”, “literary direction”, “big style”, “artistic method”. The research used the methods of a typological and complex study of literary works, which in the synthesis of literary criticism and philosophy determine the strategy of searches in the field of theoretical and methodological content of the “idea of human” category as the foundation of the literary and philosophical anthropology of cultural and historical eras. The historical and genetic links between the worldview aesthetic principles and the artistic practice of literary trends are problematized. The logic of the research reveals the concept “object – knowledge”, fundamental for epistemology, in the aspects of the structuring of the knowledge of the methodological semantics of the “idea of human” category and of the functioning of the definitions “generalized idea of human”, “type of attitude to the world”, “concept of human and reality”, “whole of human”, “human as a value”. The article shows that the “idea of human” as a philosophical and aesthetic interpretation of the nature and essence of human at a certain stage in the development of artistic consciousness, worked out by the whole culture (R.R. Moskvina, G.V. Mokronosov) and defining integrity and logical consistency of the artistic system, is a synergistically functional semantic core of the historical and cultural era, and this core contains the dialectical potential of “negation of the negation”. As a variable, the historical “idea of human”, in the perspective of the stage development of artistic consciousness, undergoes dramatic changes and is realized in the logic of the successive change of historical and cultural epochs and their philosophical paradigms, in the constant alternation of “realistic” and “mystical”, materialistic and idealistic methods of cognition and images of human and the world (D.I. Chizhevsky, A.M. Panchenko, and others). The conclusions are substantiated that the successive development of literary trends, creative methods and their axiological systems is conditioned by the dynamics of “types of attitude to the world”; that the functioning of the “idea of human” category in literary discourse is focused on argumentation of the ontological nature of fiction, on the identification of philosophical and aesthetic principles that determine the systematic nature and the successive change of artistic and cognitive cycles; that the evolution of the “idea of human” within the framework of one artistic and cognitive cycle is fixed by the dynamics of genre systems since, in the correlations of method, genre and style, “the idea of human” acts as a factor in genre formation.

The incidence of cervical cancer in the world is 17 per 100,000 women, while the mortality rate ranges from 8.2 per 100,000 women. One therapy for cancer treatment is chemotherapy. The side effects caused by chemotherapy are nausea and vomiting. In addition to drugs, complementary therapy given to chemotherapy patients is chamomile aromatherapy. This study aims to determine the effect of chamomile aromatherapy on reducing the scale of nausea after chemotherapy of cervical cancer patients in Dr. Moewardi Hospital. The type of research used is quasy experiment, using a research design non equivalent with the control group pretest and posttest design. The sample used was 30 patients with the criteria of patients who experienced Acute &amp; Delayed Nausea. Analyze data used Paired Samples Test and Independent T-Test. The results showed that the average scale of nausea before chamomile aromatherapy intervention was 15.40. And the average scale of nausea after intervention was 2.87 as evidenced by the value p=0.000 (p&lt;0.05). The average value of the nausea after treatment scale in the control group was 7.33, and the nausea scale average value in the intervention group was 2.87. So that it can be concluded that there is an effect after being given chamomile aromatherapy to reduce the scale of nausea after chemotherapy with p=0.000

This article concerns “living zones of the imagination”—areas of social life in which intensive “interpretive labor” is underway. Thanks to these zones, it is possible to engage in universally accepted exercises that enable a person to “see the world through the eyes of another person” and that yet do not disturb the current socio-cultural order. They provide an important basis for understanding among people, for harmonizing meanings in the sphere of social realities, and for integration that goes beyond certain permanent boundaries and hierarchies. The basic aim of the article is to prove that hospitality, understood as a value in Polish culture, could contribute to a considerable degree to the creation of such zones. The author analyzes the zones’ character, function, and meaning, paying attention to how they resist the expansion of bureaucratic ways of organizing social life. He also draws attention to the influence that an axio-normative pattern could havewithin specific models of behavior and cultural practices.

The study is concentrated on examination the impact of FDI on economic growth in the World during 1975–2015. The study consists of four consecutive parts, including introduction, literature review, model and methodology, data, empirical results and conclusion. Each part of the study is focused on its own goals. According to the results of the literature review, there is positive influence of FDI on economic growth in various countries. Economic growth is one of the most important goals of any country. The country image on the international level is dependent on its economic power. Economic growth provides an opportunity to improve the living standards in the country. Most researchers conclude that there is a positive influence of FDI on the countries’ economic growth. However, the impact of FDI is strong in developing countries. Moreover, this relationship is stronger in countries with higher educational and technological level, trade openness and development of the countries’ stock markets. Economists often build regression models to estimate the relationship between the variables. In order to find the impact of FDI on economic growth, we are going to apply linear regression models. We take two variables as indicators of the countries’ economic growth, including current GDP expressed in U.S dollars, and annual GDP growth rate. Taking into account that the World’s GDP in current U.S dollar is a factor variable with the mentioned resulting variables, the regression equation looks as follows: The R-squared of the built model is 0.99, indicating that roughly 100% of changes in the World’s GDP is caused by the chosen factors. As it is seen from the SAS output, the residuals of dependent variable and factors variables are distributed normally among its average value. Thus, non-normality is not observed in the model. Taking into account the coefficients of the factor variables, the log GDP is most sensitive to the changes in trade as a percent of GDP. The log GDP is not quite sensitive to the changes in FDI, since the coefficient of 0.000128 means that increasing of FDI by one unit increase the logarithmic value of GDP by $ 0.000128.


The article presents the developed method for the quantitative evaluation of involvement of countries of the world in the international open access movement. It consists in the identification of eight country open access indicators initially connected with the open access initiatives and instruments, their weighing, normalization and aggregation in the form of a weighted average value. In a second more strict approximation the number of indicators has been reduced up to six for the account of discarding the data duplicated in ROAR and Open DOAR. Budapest initiative and Berlin declaration were considered as the ОА-initiatives, and data from the international registers DOAJ, SHERPA/RoMEO, ROAR MAP and the Webometrics ОА-repositories ranking was considered as the instruments. The calculation is done on the basis of the developed method for 133 countries.
