Asymmetry in zeta Auriage chromospheres

Asymmetry in the ultraviolet spectra of zeta-Aur, similar to that reported in optical observations, was studied using IUE data. A plot of the integrated flux of zeta Aurigae from 1625 to 1675 A as a function of absolute phase shows no significant difference between the ingress and egress phases. A plot of the integrated flux from 1625 to 1675 A for 22 Vul as a function of absolute phase for both ingress and egress confirms that the atmospheric eclipse is asymmetric in 22 Vul. The eclipse in 22 Vul begins symmetrically but departs from symmetry at a phase greater than 0.05. The pronounced dip at ingress suggests a feature in the chromosphere

The Citizenship of Others

The liberal notion of citizenship provides equality to all citizens, without regard to ascriptive or other differentiating characteristics. In this sense, citizenship promises to be dispositive of the treatment of all individuals who enjoy it; citizenship is uniform, unalloyed, and indivisible. These are the attributes of citizenship within a liberal national system, governing the relationships between citizens and the state, and among citizens within the state. But must these characteristics extend into the international realm, or may states choose to look beyond the mantle of citizenship when evaluating the citizens of others? And if states do choose to differentiate, and thereby discriminate, among the citizens of others, what obligations do those citizens\u27 states bear? This Article considers two instances in which the formal equality of citizenship is jeopardized by discrimination on the basis of national origin (the place of one\u27s birth) and ancestry (the place of one\u27s ancestors\u27 birth)

Locating ethnicity and health: exploring concepts and contexts

With the rapid development of ethnicity and health as a field of sociological research, this paper seeks to re-evaluate the development of ideas around ethnicity, 'race' and culture and consider how they have been applied to the question of health. Ethnicity as a social characteristic is contingent on the situation in which it is manifest. The process of marking 'other' ethnic groups includes stereotyping and racialisation, a process through which 'racial' or ethnic differences predominate to the exclusion of a consideration of social, economic and power relations. In the British context, the history of empire and medicine's justification of racist treatment of enslaved and colonised people, is relevant to understanding how ethnic and cultural differences have come to be essentialised and pathologised. Immigration to Britain only became a mass phenomenon after World War II, with settlement patterns following employment opportunities and kinship alliances. The state has a longstanding history of 'managing' diversity, sometimes essentialising differences between groups, at other times tackling disadvantage and discrimination experiences through policy action. Sociologists of health were slow to study ethnicity, with initial research coming from tropical disease specialists. The tendency of medicine to pathologise minority cultures is explored through case studies of the approach to rickets and the assessment of health risks associated with consanguineous marriage. Anti-racist approaches have encouraged the consideration of discrimination against and socioeconomic position of minorities. The field has developed with work on nomenclature and the operationalisation of ethnic identity, necessary to study health inequalities between ethnic groups and paying due heed to the contribution of socioeconomic position and racism to group experiences. Research into chronic conditions with complex analysis of a number of distinct contributory variables has been published of late. However, the excessive focus on South Asians and the record of measuring, analysing, but not necessarily tackling health disadvantage, are problems that remain to be addressed

Antioxidant Activity of Some Selected East Borneo Plants

The native plants of East Borneo the Costus specious (Koening) J.E. Smith stem, Lagerstroema spesiosa Pers leaf, Cerbera mangans L leaf, Vitis trifolia L fruit., Scurrula atropurpurea (Blume) Danser root, Brucea javanica (L.) Merr. leaf, Lygodium microphyllum, Bidens Chinensis Willd., Sonneratia caseolaris L. peel, Sonneratia caseolaris L. stem is almost under-explored for their potensial benefits. They were extracted by the solvents of increasing polarity (n-hexane, ethyl acetate, and n-butanol) were tested for their free radical activity against DPPH (2,2-diphenyl-1-picrylhydrazyl). The ethyl acetate extract of Costus spesiosus (Koening) J. E. Smith antioxidant were screnned concentration of 68 ppm, similarly athyl acetate extract of Vitis trivolia L., showed antioxidant activity at 64,30 ppm. As the ethyl acetate extract of Scurrulla atropurpurea (Blume), Brucea javanica (L.) Merr, Lygodium microphyllum and Sonneratia caseolaris L. stem, showed antioxidant activity at 273,52 ppm, 91,12 ppm, 17,39 ppm and 7,03 ppm. N-butanol extract of Lagerstroema spesiosa Pers, Cerbera mangans L, Bidens chinensis Willd, and Sonneratia caseolaris L. peel showed 8,37 ppm, 128,59 ppm, 18,17 ppm and 54,29 ppm antioxidant activity using DPPH model systems. Owing to the property, the studies can be further extended to exploit them for their possible application for preservation of food products as well as their use as health supplements

Sociolinguistics Perspectives on Gender Patterns in Instagram

This article focused on the the gender patterns that were found in the social media Instagram based on the sociolinguistics point of view. There were two research questions were arisen what types of the gender patterns that were found in the social media Instagram based on the sociolinguistics and the factors of the difference language used based on gender in social media Instagram. Uses and Gratifications Theory (UGT) was used to analyze the data. The data was taken from all of component of the sociolinguistics aspect in social media network especially for gender patterns that existed on the social media instagram college students' users id in Pekanbaru. The writer took 30 Instagram users id as sample. The study found that two types of gender patterns, first; gender in writing and second; gender in profile photo, thus there were five main assumptions that caused the differences language in gender in social media Instagram, namely; (1) an audience is active and goal-oriented in their media consumption, (2) media are used for gratifications, (3) media are in competition with other means of need satisfaction, (4) people understand their personal media use, interests, and motives enough to communicate with researchers about their choices, (5) the audience members are the only people who can make judgments regarding the value of the media content. The study recommends that sociolinguistics is an interesting topic to be researched thus future field of study concerns with the rapid changing phenomena in social media

On Distinguishing Non-Standard Interactions from Radiative Corrections in Neutrino-Electron Scattering

We present a contribution of higher order to neutrino-electron scattering that is a charged-current counterpart of both the anomalous axial-vector triangle and possible non-standard interaction contributions. It arises in the standard model with massive neutrinos, and renormalizes the nondiagonal axial-vector form-factor at low energies. We show that, due to the small size of radiative corrections, the neutrino-electron scattering still provides a discovery potential for some of the non-standard neutrino interactions proposed in the literature.Comment: 9 pages, 3 figures, change in title and context of the consideration, results of radiative corrections unchange

Digital predictions of complex cylinder packed columns

A digital computational approach has been developed to simulate realistic structures of packed beds. The underlying principle of the method is digitisation of the particles and packing space, enabling the generation of realistic structures. Previous publications [Caulkin, R., Fairweather, M., Jia, X., Gopinathan, N., & Williams, R.A. (2006). An investigation of packed columns using a digital packing algorithm. Computers & Chemical Engineering, 30, 1178–1188; Caulkin, R., Ahmad, A., Fairweather, M., Jia, X., & Williams, R. A. (2007). An investigation of sphere packed shell-side columns using a digital packing algorithm. Computers & Chemical Engineering, 31, 1715–1724] have demonstrated the ability of the code in predicting the packing of spheres. For cylindrical particles, however, the original, random walk-based code proved less effective at predicting bed structure. In response to this, the algorithm has been modified to make use of collisions to guide particle movement in a way which does not sacrifice the advantage of simulation speed. Results of both the original and modified code are presented, with bulk and local voidage values compared with data derived by experimental methods. The results demonstrate that collisions and their impact on packing structure cannot be disregarded if realistic packing structures are to be obtained
