Abstract Freshwater crustaceans are distributed throughout the montane and lowland areas of Colombia, and are therefore a useful indicator group for how aquatic species will respond to climate change. As such, metabolic determination of physiological performance was evaluated for the Colombian pseudothelphusid crab, Neostrengeria macropa (H. Milne Edwards, 1853), over a temperature range inclusive of current temperatures and those predicted by future scenarios in the plateau around the city of Bogotá, namely from 8 °C to 30 °C. The performance results mostly aligned with previous exploratory behavioral determination of the ideal temperature range in the same species, although the metabolism increased at the highest temperature treatments, a point when exploratory behavior declined. These results indicate that this species of montane crab behaviorally compensates for increased thermal stress by decreasing its physical activity, which could have negative predator-prey consequences with changes to community structure as different species undergo climate-mediated geographic range shifts in the region. As this species is endemic to the plateau surrounding Bogotá, it also experiences a number of other stressors to its survival, including infrastructure development and invasive species.

Abstrak This paper will explore aspects of research methodology of exegesis written by Aksin Wijaya related to methods nuzuli ala Muhammad Izzat Darwazah. For that, the focus of this discussion is the methodology of his research in his own book of under title Sejarah Kenabian Dalam Perspektif Tafsir Nuzuli Muhammad Izzat Darwazah, finding out how people review mufassir. Specifically, the methodical determination of the previous his experienced has moved soon of orientation from the critical to the descriptive while facing of four books, namely: Tafsir al Hadith, 'Ashr al Nabiy wa Biatuhu Qabla al Bi'tsah, Sirah al Rasul; Suwar Muqtabasah min al Qur'an, and ad Dustur al Qur'an fi Su'uni al Hayat works of thinkers and historians. From his reading, he at least analyzes his views into two important parts, namely; 1) the interpretation method of nuzuli and the ideal concept it contains, 2) it then draws it into the realm of pre-Islamic, personal and family life of the prophet Muhammad, to the condition of the people of prophetic era through the perspective of nuzuli Izzat Darwazah exegesis. According to the reviewer, there are other research elements in writing the work of the exegesis, namely some models of research methods of interpretation at once, such as: comparative research, character research, and thematic-nuzuli research. Whereas although placed more as an overview of nuzuli interpretation, at least he invites readers, especially in Indonesia to re-read the tafsir nuzuli treasury and see which is as worthy to be developed in the turats of Islam Nusantara. Abstrak Tulisan ini hendak menelusuri aspek metodologi penelitian tafsir yang dilakukan oleh Dr. Aksin Wijaya terkait metode nuzuli ala Muhammad Izzat Darwazah. Untuk itu, fokus dari pembahasan ini adalah tentang metodologi penelitiannya dalam buku berjudul Sejarah Kenabian Dalam Perspektif Tafsir Nuzuli Muhammad Izzat Darwazah untuk mengetahui bagaimana orang mengkaji mufassir. Dimana secara khusus mulai penentuan metodis dari sebelumnya ia mengalami pergeseran orientasi dari kritis ke deskriptif dalam menghadapi empat kitab hasil perburuannya, yaitu: Tafsir al Hadits, ‘Ashr al Nabiy wa Biatuhu Qabla al Bi’tsah, Sirah al Rasul; Suwar Muqtabasah min al Qur’an, dan ad Dustur al Qur’an fi Su’uni al Hayat karya tokoh pemikir dan sejarawan. Dari pembacaannya tersebut, ia setidaknya menganalisa pandangannya menjadi dua bagian penting, yaitu; 1) metode tafsir nuzuli dan konsep ideal yang dikandungnya, 2) kemudian ia menariknya ke ranah kehidupan masyarakat pra-islam, pribadi dan keluarga nabi Muhammad saw, hingga kondisi masyarakat era kenabian melalui perspektif tafsir nuzuli Izzat Darwazah. Pun demikian, menurut penulis ada unsur penelitian lain dalam penulisan karya Aksin tersebut, yaitu beberapa model metode penelitian tafsir sekaligus, seperti: penelitian perbandingan, penelitian tokoh, dan penelitian tematik-nuzuli. Dimana walaupun diletakkan lebih sebagai gambaran umum tafsir nuzuli, setidaknya ia mengajak pembaca khususnya di Indonesia untuk meneelaah kembali khazanah tafsir nuzuli dan memandang mana yang sekira layak untuk dikembangkan dalam turats Islam ke-Indonesia-an.

The purpose of this article is a philosophical and anthropological analysis of the ideal of androgyne in V.V. Rozanov’s metaphysics of sex. The main focus is on the comparison of the destructive and constructive forms of the androgyne in his philosophy. According to the philosopher, destructive forms include people of «moonlight» or «third sex», who are considered the founders of New Testament Christianity, denying the life of the flesh. Constructive forms are the natural androgyny of a child and the androgyny of a married couple, which reveals itself in love, dynamics, mutual complementarity of a man and a woman. The paper draws parallels between N.A. Berdyaev’s and V.V. Rozanov’s concepts of androgyne, which are antipodal in terms of direction of thought but have common meanings. It is concluded that thesimilarity between the concepts lies in the understanding of gender as a dynamic and metaphysical principle that penetrates through not only the bodily but also the spiritual life of a person, and therefore cannot be rejected. The concepts are also similar in that they draw a boundary between the androgyne and the hermaphrodite, of which the former is the ideal of the human wholeness, while the latter is an unsuccessful attempt to achieve it. The differences between these philosophers consist in the priority of spiritual love in Berdyaev’s system and worldly, bodily love in Rozanov’s, as well as in a different understanding of the process of an androgyne being generated in a person, which, in Berdyaev’s conception, is individual and arises in each of the persons who are in love with each other, while, according to Rozanov, it is exclusively achievable in couples. The paper also pays attention to Rozanov’s own theology, which renews the Old Testament family ideals, offering the concept of God as a «sexual» being and proposing to consider the act of love within marriage as a sacred mystery that unites a person with God in co-creation. The study allows us to rethink the modern problems of gender self-determination of a person, returning to the metaphysical foundations of the Russian philosophy of gender, the main task of which was the synthesis of the spiritual and bodily principles in a person.

The Ideal

The standard procedure to determine (analytically) the values of the quark masses is to relate QCD two-point functions to experimental data in the framework of QCD sum rules. In the case of the light quark sector, the ideal Green function is the pseudoscalar correlator which involves the quark masses as an overall multiplicative factor. For the past thirty years this method has been affected by systematic uncertainties originating in the hadronic resonance sector, thus limiting the accuracy of the results. Recently, a major breakthrough has been made allowing for a considerable reduction of these systematic uncertainties and leading to light quark masses accurate to better than 8%. This procedure will be described in this talk for the up-, down-, strange-quark masses, after a general introduction to the method of QCD sum rules.

AbstractThe electron probe is shown to be an effective tool for the analysis of the series of ferrimagnetic oxides referred to as the hexagonal ferrites. This series of compounds) containing barium, Fe3+, and a divalent metal cation, is formed by an ordered stacking of basic structural units in varying ratios. The ideal, complex stoichiornewy of these polytype-like mixed-layer structures can be computed from X-ray unit cell data; the various structures and their predicted stoichiometry are reviewed. Results of electron probe analysis of zinc-bearing single-crystal hexagonal ferrites are compared with theoretical values, the various correction procedures applied to the probe data are presented, and the limitations of the method in the analysis of hexagonal ferrites are discussed. The information obtained from this study has laid the groundwork for the determination of chemistry in substituted members of the hexagonal ferrite group, and will contribute significantly to the interpretation of the magnetic properties exhibited by these compounds.
