According to the theory of Faber and Ziman the electrical resistivity of Ag-Mg alloys was calculated from X-ray diffraction data. The pseudo-potentials of Animalu and Heine were used. The calculated results agree well with the data measured by the rotating field method. The calculation of partial interference functions for the different kinds of alloy systems are discussed extensively.

In this paper, the transmission characteristics of rubidium excited state Faraday anomalous dispersion optical filters at 532nm for a practical and important wavelength are analyzed and discussed. A weak magnetic field method is employed to calculate the transmission characteristics versus external magnetic field, laser pump power, cell temperature and cell length for natural Rb,85Rb and87Rb atomic vapors, respectively. The theoretical results show that the transmission property of85Rb atomic vapor is superior to that of Rb,87Rb atomic vapors in the weak magnetic field, which makes it more suitable for the magneto-optic filtering material of Faraday optical filters by comparison with natural Rb atomic vapor.

Dark Field Electron

A number of satisfactory methods are available for the electron microscopy of nicleic acids. These methods concentrated on fragments of nuclear, viral and mitochondrial DNA less than 50 megadaltons, on denaturation and heteroduplex mapping (Davies et al 1971) or on the interaction between proteins and DNA (Brack and Delain 1975). Less attention has been paid to the experimental criteria necessary for spreading and visualisation by dark field electron microscopy of large intact issociations of DNA. This communication will report on those criteria in relation to the ultrastructure of the (approx. 1 x 10-14g) DNA component of the kinetoplast from Trypanosomes. An extraction method has been developed to eliminate native endonucleases and nuclear contamination and to isolate the kinetoplast DNA (KDNA) as a compact network of high molecular weight. In collaboration with Dr. Ch. Brack (Basel [nstitute of Immunology), we studied the conditions necessary to prepare this KDNA Tor dark field electron microscopy using the microdrop spreading technique.

Beam Technique

The “weak-beam” and systematic many-beam techniques are the currently available methods for resolution of closely spaced dislocations or other inhomogeneities imaged through strain contrast. The former is a dark field technique and image intensities are usually very weak. The latter is a bright field technique, but generally use of a high voltage instrument is required. In what follows a bright field method for obtaining enhanced resolution of partial dislocations at 100 KV accelerating potential will be described.A brief discussion of an application will first be given. A study of intermediate temperature creep processes in commercial nickel-base alloys strengthened by the Ll2 Ni3 Al γ precipitate has suggested that partial dislocations such as those labelled 1 and 2 in Fig. 1(a) are in reality composed of two closely spaced a/6 <112> Shockley partials. Stacking fault contrast, when present, tends to obscure resolution of the partials; thus, conditions for resolution must be chosen such that the phase shift at the fault is 0 or a multiple of 2π.

AbstrakPenelitian ini bertujuan mengkaji perbandingan kepercayaan masyarakat Talagadi Majalengka dan masyarakat Nagoya di Jepang. Kepercayaan yang dimaksud dalampenelitian ini adalah kepercayaan yang berhubungan dengan tabu atau pamali dankepercayaan yang berhubungan dengan keberuntungan pada kedua masyarakat tersebut.Untuk mencapai tujuan tersebut digunakan metode deskripstif kualitatif. Dalam memupudata digunakan metode lapangan karena peneliti terjun langsung ke masyarakat. Disamping itu, digunakan pula metode survey melalui penyebaran daftar kuesioner. Hasilpenelitian menunjukkan bahwa bentuk kepercayaan yang berhubungan dengan tabu ataupamali pada masyarakat Talaga dan Nagoya meliputi kegiatan yang dilakukan oleh manusia.Adapun kepercayaan yang berhubungan dengan keberuntungan pada kedua masyarakattersebut berkaitan dengan binatang, benda, dan kegiatan manusia. Sampai saat ini baikmasyarakat Talaga maupun Nagoya masih memegang teguh kepercayaan tersebut.Kata kunci: kepercayaan, Talaga, Nagoya, deskriptif kualitatif, komparasi budaya.AbstractThe aim of this research is to review the comparison of belief between the society ofTalaga in Majalengka and the society of Nagoya in Japan. The intended belief on this study isthe one related with a taboo or pamali, and the belief correlated to luck on both societies. Inachieving the goal, this research uses a descriptive qualitative method. To get the data, thewriter uses a field method that he (/she) directly involves with the people. On the other hand,the writer also uses a survey method by distributing questioners. The result shows that the beliefcorrelated with the taboo or pamali of Talaga and Nagoya societies covers the activities doneby human. Also with the belief related to luck of both societies corresponds to animals, things,and human’s activities. Until now, either Talaga society or Nagoya’s still keeps those beliefs.Keyword: belief, Talaga, Nagoya, descriptive qualitative, cultural comparison.
