This paper describes four different configurations of active devices integration into log periodic antennas (LPAs). The first configuration involves the integration of a single amplifier at the input feed line of a five element log periodic antenna (LPA). The second configuration involves the integration of an amplifier in the middle of the five elements LPA. The third configuration is the five element LPA with individual amplifiers in each element. The last configuration involves the integration of the individual amplifiers and filters with five element LPA in each element. The performance of these configurations have been investigated and compared in terms of the bandwidth, gain relative to a passive LPA, cross polar isolation and half power beamwidth. Key words: Log periodic antenna, active integrated antenna, microstrip antenna, wideband antenna

Abstract To account for the effects of multiple impairments, evaluating physicians must provide a summary value that combines multiple impairments so the whole person impairment is equal to or less than the sum of all the individual impairment values. A common error is to add values that should be combined and typically results in an inflated rating. The Combined Values Chart in the AMA Guides to the Evaluation of Permanent Impairment, Fifth Edition, includes instructions that guide physicians about combining impairment ratings. For example, impairment values within a region generally are combined and converted to a whole person permanent impairment before combination with the results from other regions (exceptions include certain impairments of the spine and extremities). When they combine three or more values, physicians should select and combine the two lowest values; this value is combined with the third value to yield the total value. Upper extremity impairment ratings are combined based on the principle that a second and each succeeding impairment applies not to the whole unit (eg, whole finger) but only to the part that remains (eg, proximal phalanx). Physicians who combine lower extremity impairments usually use only one evaluation method, but, if more than one method is used, the physician should use the Combined Values Chart.

The current pandemic has seen some adverse reactions from the most diverse religious groups all over the world to government regulations. After having described some of their manifestations, this contribution analyzes what the Bible and some post biblical (patristic and Talmudic) traditions say about illness and pandemics. As it is ascertained that these sources contain very limited material on these subjects, the third part of this article proposes some ethical reflections regarding the official response to the pandemic as well as some pastoral implications.

Academic Year

In the Reflective Practice column of the third issue of the Relay Journal, Yamamoto (2019) remarked on the importance of creating a platform for advisors to voice their views, feelings, and experiences, and suggested a need for more reflective narratives to be posted from different social, historical, and cultural contexts in order to provide an intimate view inside advising sessions, thereby offering a better understanding of said advising practices. The aim was to create a forum where advisors could learn from each other, and ultimately, everyone could mutually benefit from the experiences shared. To further this innovative research into Advising in Language Learning (ALL), the initial experiment by language advsiors at Kanda has been replicated in a different setting with four learning advisors from Ankara Yıldırım Beyazıt University, Turkey. The design used by the advisors at Kanda, a narrative style adopted while telling the stories, has been expanded to include a visual message board to which 20 learning advisors have contributed with their short reflective captions on their advisor selves. Additionally, the theme used by the advisors at Kanda, “the most memorable advising experience of this academic year” has been altered in our case to avoid repetition and to allow reflection on different aspects of the advising experiences. Thus, our narratives and the visual message board will examine two different themes: (1) How has advising affected you? (2) How do you define yourself as an advisor? Four narratives have elaborated on the first theme of the influence of advising knowledge and practice on the individual advisors, and the visual message board includes 20 images with reflective captions on the second theme of defining advisor identities.

If, as Chapter 12 argues, much of Bonhoeffer’s resistance thinking remains stable even as he undertakes the novel conspiratorial resistance, what is new in his resistance thinking in the third phase? What receives new theological elaboration is the resistance activity of the individual, which in the first two phases was overshadowed by the resistance role played by the church. Indeed, as this chapter shows, Bonhoeffer’s conspiratorial activity is associated with what he calls free responsible action (type 6), and this is the action of the individual, not the church, in the exercise of vocation. As such, the conspiratorial activity is most closely related to the previously developed type 1 resistance, which includes individual vocational action in response to state injustice. But the conspiratorial activity differs from type 1 resistance as individual vocational action in the extreme situation.

ABSTRACT A statistical analysis of DNA sequences from four nuclear loci and five mitochondrial loci from different orders of mammals is described. A major aim of the study is to describe the variation in the rate of molecular evolution of proteins and DNA. A measure of rate variability is the statistic R, the ratio of the variance in the number of substitutions to the mean number. For proteins, R is found to be in the range 0.16 < R < 35.55, thus extending in both directions the values seen in previous studies. An analysis of codons shows that there is a highly significant excess of double substitutions in the first and second positions, but not in the second and third or first and third positions. The analysis of the dynamics of nucleotide evolution showed that the ergodic Markov chain models that are the basis of most published formulas for correcting for multiple substitutions are incompatible with the data. A bootstrap procedure was used to show that the evolution of the individual nucleotides, even the third positions, show the same variation in rates as seen in the proteins. It is argued that protein and silent DNA evolution are uncoupled, with the evolution at both levels showing patterns that are better explained by the action of natural selection than by neutrality. This conclusion is based primarily on a comparison of the nuclear and mitochondrial results.

Abstract Cooperation is a prevailing feature of many animal systems. Coalitionary aggression, where a group of individuals engages in coordinated behaviour to the detriment of conspecific targets, is a form of cooperation involving complex social interactions. To date, evidence has been dominated by studies in humans and other primates with a clear bias towards studies of male-male coalitions. We here characterize coalitionary aggression behaviour in a group of female carrion crows consisting of recruitment, coordinated chase, and attack. The individual of highest social rank liaised with the second most dominant individual to engage in coordinated chase and attack of a lower ranked crow on several occasions. Despite active intervention by the third most highly ranked individual opposing the offenders, the attack finally resulted in the death of the victim. All individuals were unrelated, of the same sex, and naïve to the behaviour excluding kinship, reproduction, and social learning as possible drivers. Instead, the coalition may reflect a strategy of the dominant individual to secure long-term social benefits. Overall, the study provides evidence that members of the crow family engage in coordinated alliances directed against conspecifics as a possible means to manipulate their social environment.

AbstractPs. lxxxix is in many ways the most interesting and important of the royal psalms. Taken as a whole it is a lamentation (vss. 39-52) over the frustration of God's promises to the Davidic dynasty (vss. 20-38), which were made possible by his cosmic sovereignty (6-15). The first part of the psalm recalls the hymns of Yahweh's enthronement (xlvii, xciii, xcv-c), the second, the oracle of Nathan (2 Sam. vii; Ps. cxxxii), and the third, the individual lamentations of the Psalter. This complexity of form and content has led most commentators to divide the psalm into two or three originally separate poems, and to interpret their significance more or less independently of each other. It is the aim of the present study to demonstrate the formal integrity of the psalm as it appears in the Psalter, and to discover, if possible, its original liturgical setting.

Abstract Equity and solidarity are strongly embedded in Slovene society from the second half of the 20th century on. Questions, exploring equity issues date in 1964, as a part of the Slovene Public Opinion (SPO) Survey. Slovenia is reporting on health equity and wellbeing in three strands. The first one is regular Human Development Report, based on Slovene Development Strategy since 2007, delegated partially to Institute of Economic Research (IER). Second one is regular Inequalities in Health Report, led by National Institute of Public Health (NIPH), and based on the National Health Strategy, since 2011. The third one is regular Poverty Report, led by Institute of Social Protection (ISP), based on the decision of the Parliamentarian Commission for Health and Social Affairs in 2013. NIPH comprehensively reported on Inequalities in Health in 2011, at that time based on direct measures of socio-economic status (SES) like education, or indirect measures or indexes (as development index or deprivation index of the municipality). In the second, 2018 report, several developments enabled for reporting health equity gap based on the individual SES status and first few cases of policy influences on equity status were described. In line with the WHO Rio SDH declaration 2011, in the third Health Equity Report, planned for 2021, further shift is foreseen and focus will be given to the policies influencing the equity gaps. For the 2021 Health Equity Report for Slovenia, three national key institutions (NIJZ, IER and ISP) decided to work together, based on the established multisectoral competences. WHO HESRi was developed and launched in best possible timing for the Slovene national initiative, to provide the international support, insights and facilitate further national development. Slovene priorities will be defined according to the national interests, Slovene presidency to EU in 2021 and Country Specific Recommendations in the frame of the European Semester.

ASOCIAL “WE” The problems discussed in the book are revealed by the well-known view of Aristotle that man is a cultural, social and political being: ...And he who by nature and not by mere accident lives outside the state, is either a wretch or superhuman being; he is ‘without lineage, law, hearth,‘ as denoted by Homer, because if someone is such a person by nature, he desires passionately war, being isolated, as a stone excluded from dice. Furthermore, It appears that the state is a creation of nature and most of all concerns the individual because when each person separately is not self-sufficient, he will be placed in the same relation to the state like these and other parts in relation to a whole. However, one who is unable to live in the community, or does not need it at all, being self-sufficient, such a person is not a member of the state, so he must be either a beast or god. Directed by the spirit of contrariness, I will add Friedrich Nietzsche’s comment : “Aristotle says that in order to live alone one must be either an animal or a god. The third alternative is lacking. A man must be both – a philosopher.”
