Particle Induced X-ray Emission (PIXE) was used to analyse the elemental concentration of gallstones collected from different parts of south India. Cholesterol gallstones are predominant in north India, whereas pigment gallstones are predominant in south India. The black pigment gallstones are common in hemolytic anemia or in presence of infected bile. PIXE has revealed the elemental profile in each sample. The experimental subjects of the different groups displayed significant variation in their levels of certain trace elements such as copper, zinc, and iron. The concentration of copper was found to be predominant in pigment gallstones investigated in the present study.

Good Agreement

The method of total reflection fluorescence analysis was used to obtain concentrations of iron, copper, zinc, and bromine in human sera. It was first applied to the commercial control-serum preparation known as Seronorm, and the results obtained were in good agreement with quoted values. The method was then used to determine the concentrations of iron, copper, zinc, and bromine in a random sampling of 62 individuals in an essentially Chinese population. The results are discussed. We feel that this is a suitable method for trace-element analysis of blood in an average laboratory. It is rapid, simple, and economical, besides being multielemental and nondestructive and requiring very small quantities—which seems to be a must in pediatrics.

Bacterial symbionts present in the indeterminate-type nitrogen (N)-fixing nodules of Mimosa pudica grown in North and South India showed maximum similarity to Ralstonia taiwanensis on the basis of carbon-source utilization patterns and 16S rDNA sequence. Isolates from the nodules of M. pudica from North India and South India showed identical ARDRA (Amplified Ribosomal DNA Restriction Analysis) patterns with Sau3AI and RsaI, but AluI revealed dimorphy between the North Indian and South Indian isolates. Alignment of 16S rDNA sequences revealed similarity of North Indian isolates with an R. taiwanensis strain isolated from M. pudica in Taiwan, whereas South Indian isolates showed closer relatedness with the isolates from Mimosa diplotricha. Alignment of nifH sequences from both North Indian and South Indian isolates with that of the related isolates revealed their closer affinity to α-rhizobia, suggesting that nif genes in the β-rhizobia might have been acquired from α-rhizobia via lateral transfer during co-occupancy of nodules by α-rhizobia and progenitors of R. taiwanensis, members of the β-subclass of Proteobacteria. Immunological cross-reaction of the bacteroid preparation of M. pudica nodules showed strong a positive signal with anti-dinitrogenase reductase antibody, whereas a weak positive cross-reaction was observed with free-living R. taiwanensis grown microaerobically in minimal medium with and without NH4Cl. In spite of the expression of dinitrogenase reductase under free-living conditions, acetylene reduction was not observed under N-free conditions even after prolonged incubation.Key words: symbiotic nitrogen fixation, Mimosa pudica, rhizobia, phylogeny, 16S rDNA, nifH, Ralstonia taiwanensis.

Hindustani Classical Music

In Sri Lanka, the various groups of Tamils are jointly the largest minority group who migrated from different places of South India and in different time periods. South Indian music is widely appreciated and learnt by both the Sinhala including by large parts of the Tamil minority spread over Sri Lanka. Although a number of Sinhala people prefer and practice North Indian music geographically, and probably culturally, they are much closer to South India than to North India. Some historical sources report that Sinhalese are descendants of North Indians who are believed to be Aryans who migrated from Persia to the Northern part of India in the 13th century and later. Therefore, some scholarly authorities believe that the Sinhalese ‘naturally’ prefer North Indian music as they also continue the suggested Aryan heritage. Nevertheless, some other sources reveal that the North Indian music was spread in Sri Lanka during the British rule with the coming of the Parsi Theatre (Bombay theatre), which largely promoted Hindustani raga-based compositions. This paper explores selected literature and opinions of some interviewees and discusses what could be the reasons for preferences of North Indian music by the Sinhalese. The interviewees were chosen according to their professional profile and willingness to participate in this research. As a result, this paper will offer insights through analysing various opinions and statements made by a number of interviewees. The research also considered some theories which may relate to the case whether Hindustani classical music is due to these reasons a dominating minority culture or a rather self-imposed musical ideology. The latter would establish an aesthetic hierarchy, which is not reflected in the cultural reality of Sri Lanka. This is a new research scrutinizing a long-term situation of performing arts education in this country taking mainly interviews as a departing point.

The cag pathogenicity island (cagPAI) has been reported to be the major virulence determinant in Helicobacter pylori-related diseases. In the present study, the diversity of the cagA gene and the integrity of the cagPAI in 158 H. pylori strains from Varanasi (North India) and Hyderabad (South India) were studied by amplifying the cagA gene (∼3.5 kb), followed by PCR-RFLP analysis. The results revealed significant differences in the cagA gene and the integrity of the cagPAI between North and South Indian isolates. Of 158 isolates, 40 (34.8 %) from Varanasi and 20 (46.5 %) from Hyderabad were found to carry an intact cagPAI. A partially deleted cagPAI was present in 75 (65.2 %) isolates from Varanasi and 23 (53.5 %) from Hyderabad. None of the isolates showed complete deletion of the cagPAI. Differences in the cagA 5′ and 3′ regions were also noted, and 11 isolates (8 from Varanasi and 3 from Hyderabad) that were cagA negative with primers for the 5′ region turned out to be cagA positive with primers for the 3′ variable region. It is tentatively concluded that the 3′ variable region may be a better marker for cagA typing. The results also showed that the majority of the isolates harboured the Western-type EPIYA motif. PCR-RFLP analysis of the cagA gene showed 29 distinguishable digestion patterns, and cluster analysis of RFLP types from a random selection of 32 isolates placed all of the isolates into 5 groups. These results demonstrate that significant differences in the cagPAI occur among isolates from North and South India, and that RFLP of cagA could be employed for elucidating genetic variations among various isolates of H. pylori.

Abstract- Hinduism is a religion that was born in India and has developed rapidly into the archipelago with evidence of Sanskrit inscriptions and Pallava. The religion had a significant influence on Java which changed the political, economic, social and cultural life which at that time was still a kingdom. The arrival of Indians to Indonesia affected by the reverse flow between Indonesia and India and India and Indonesia. This can be seen by the presence of Indonesian dormitories in Nalanda (North India) and Nagapattinam (South India). The influence of North and South India can be seen from the existence of Hindu-Buddhist temples in the Archipelago which was built in one of the Hindu kingdoms, namely the Kingdom of Ancient Mataram which had areas of authority from Central Java to East Java. The temples that were built are thought to have an identity with temples in North and South India in terms of figure, inner space tectonics, mass layout, spatial planning, and ornamentation. This identity is thought to be a close relationship between North India and South India with Indonesia, especially in the era of Ancient Mataram. The purpose of this study is to find out the relationship or relationship of Ancient Mataram era temple architecture to North and South Indian temple architecture. The analysis method used is the comparative – qualitative method. Work plans, plans, pieces, site plans, and block plans of 28 Hindu-Buddha tower types in Central Java will be compared in terms of similarities and differences and then analyzed regarding the position of the laying, and elements of the temple so that the relationship between the two countries is found. Data obtained from literature studies and field surveys. The conclusion drawn from this study is that there is a closer relationship with South India than North India. The influence of North India and South India is only limited to the external appearance in the study of figure and ornamentation, while in the study of mass and spatial planning and inner space tectonics is more developed by the people of Ancient Mataram which is adjusted to traditional values and natural influences.     Key Words: figure, tectonics, mass layout, spatial planning, ornamentation, North and South India, Ancient Mataram

We present a simple expression for the quantitative treatment of interference corrections in x-ray analysis. WDS electron probe analysis of standard reference materials illustrate the success of the technique.For the analytical line of wavelength λ of any element A which lies near or on any characteristic line of another element B, the observed x-ray counts at We use to denote x-ray counts excited by element i in matrix j (u=unknown; s=analytical standard; ŝ=interference standard) at the wavelength of the analytical line of A, λA (Fig. 1). Quantitative analysis of A requires an accurate estimate of These counts can be estimated from the ZAF calculated concentration of B in the unknown C,Bu measured counts at λA in an interference standard of known concentration of B (and containing no A), and ZAF correction parameters for the matrices of both the unknown and the interference standard at It can be shown that:

Abstract In the automotive IC using thick-film silicon on insulator (SOI) semiconductor device, if the gettering capability of a SOI wafer is inadequate, electrical characteristics degradation by metal contamination arises and the yield falls. At this time, an automotive IC was made experimentally for evaluation of the gettering capability as one of the purposes. In this IC, one of the output characteristics varied from the standard, therefore failure analysis was performed, which found trace metal elements as one of the causes. By making full use of 3D perspective, it is possible to fabricate a site-specific sample into 0.1 micrometre in thickness without missing a failure point that has very minute quantities of contaminant in a semiconductor device. Using energy dispersive X-ray, it is possible to detect trace metal contamination at levels 1E12 atoms per sq cm. that are conventionally detected only by trace element analysis.
