SummaryThe distribution of trace elements is studied in different acid and basic rocks, adjacent to the copper lodes in the Mosaboni mines, Singhbhum, and adjoining the thrust zone, as well as of areas far away from the mineralized zones. Specific differences in composition and trace constituents in these rocks especially as regards S, Cu, Ni, and Co, suggest that the relationship of the Singhbhum granite with the soda granite is most unlikely, and that there is a connection between the soda granite and the sulphide ore-fluid ; a genetic relationship of sulphide mineralization with the epidiorite is doubtful. The possibility of the existence of a common source for the Chotanagpur granite and the Singhbhum granite is inferred.

Abstract Jeremiah 52 is valued among scholars for the insight it provides into the composition history of the larger book and its relationship to 2 Kings. Beyond the text-critical clues it provides, however, little is said about the relationship of Jeremiah 52 to the rest of the book. The chapter has been added to Jeremiah from its original position in 2 Kings 24–5 (or a common source), but it has been edited in the process. What follows is an exploration of a possible motivation for the addition of Jeremiah 52 to the larger book. Using the characters of Jehoiachin and Zedekiah as representatives of those who did and did not listen to the exhortation of the prophet, the editor uses the material of Jeremiah 52 to indicate that any future for the nation of Israel was located in—and would come out of—Babylon.

<p>The Tarawera Volcanic Complex is situated on the south eastern side of the Okataina Volcanic Centre, and is an association of rhyolite domes, flows and tephra, and basalt scoria. Twelve rhyolite domes are described, and using evidence obtained from the good internal sections available, the general structure of volcanic domes is discussed. Tephra stratigraphy of the Tarawera-Rerewhakaaitu region is described and by relating stratigraphy on the mountain to this tephra, four major eruptions can be recognized. A sequence of events for the Kaharoa eruption about 1020 A.D. can be postulated. The Tarawera eruption in 1886, however, was observed, and from the eye witness accounts, together with present day field evidence, a detailed account can be written. All the rocks of the Complex are described petrographically, mineralogically, and in some cases petrochemically. Twelve new full analyses; nine partial analyses of plagioclase, and eight partial analyses of residual glass are given, and the relationship of these is illustrated by variation diagrams. Finally, the origins of the acid and basic rocks of the Complex are discussed, and a hypothesis for the occurrence of the two lava types is given.</p>

Objectives: The objective of this study was to compare the level of traceelements Zinc, Cadmium and lead in seminal plasma and serum of infertile men to the fertileones. Period: June 2014 to August 2015. Setting: Pathology Department of Continental MedicalLahore, attached with Ch. Rehmat Ali Memorial Trust teaching Hospital Methods: A total of 400samples of workers working in different factories for a period of 5 or more years were collected.Out of theses 80 were azoospermic. The relationship of trace elements in serum and seminalplasma of infertile men was compared with the normospermic individual controls. Results: Theconcentration of trace elements Pb and Cd was higher in seminal plasma and serum of infertileindividuals while Zn level was lower. So it is suggested that high levels of Pb and Cd may affectthe fertility and Zn is a crucial element for sperms and fertility in men.

Studies on serum level of some trace elements in oculocutaneous albinism subject in Owerri metropolis was carried out using standard methods. Sixty (60) volunteer subjects made of 30 male and 30 female were used for the study. With the help of syringes, their sera were obtained from their blood samples and used for trace element analysis. Observed results revealed significant (p<0.05) decrease in levels of copper and zinc in male and female oculocutaneous albinism subjects against the control. The mean values for copper and zinc in both male and female also showed significant (p<0.05) reduction when compared to the control. The observed decreased in copper could influence tyrosinase and subsequently melanin production. There is need to investigate the relationship of the pigmentation disorder with other trace elements that were not considered in the present study. This study has revealed the serum level of some trace elements in oculocutaneous albinism subject in Owerri metropolis.

Certain characteristics of tolerance which develops to the pyrogenic effects of old tuberculin (OT) in BCG-vaccinated rabbits have been described. Rabbits made tolerant by several injections of OT lost their ability to produce detectable amounts of endogenous pyrogen (EP) in response to the specific agent (OT) but mobilized normal amounts of EP when given a small unrelated stimulus. On the other hand, when this stimulus followed shortly after an initial tuberculin fever of sufficient magnitude, release of additional EP was suppressed, presumably due to an inhibitory effect of the EP previously mobilized by tuberculin. Similarly, a single large dose of endotoxin almost completely suppressed the response of sensitized rabbits to OT given several hours later. Since several spaced injections of the same dosage were ineffective, this phenomenon does not appear to be attributable to the known mechanisms by which endotoxins promote non-specific resistance to toxicity and infection. Tolerance to tuberculin could not be definitely shown following an injection of Newcastle disease virus which also produces a circulating EP, and it has been inferred that endotoxin blocks the pyrogenic action of antigen on host tissues directly rather than through mobilizing EP. On the basis of these observations, the relationship of specific to non-specific tolerance to tuberculin fever has been compared in terms of the ability of such tolerant animals to mobilize EP to heterologous stimuli and it is concluded that the two forms of tolerance are different. Furthermore, the fact that a number of unrelated agents produce tolerance non-specifically supports the concept that there may be a common source of EP released by a number of stimuli, including endotoxins and myxoviruses, as well as antigen in specifically sensitized hosts.

SummaryBiotites from a number of granites have been analysed for major oxides and a wide range of trace elements. Their compositions are found to be typical of biotites from granite and to show element fractionation in presumed differentiation series. Estimates are made of the fugacity of oxygen and water during the crystallization of the granites. PH2O is found to increase slightly through the differentiation series, and fO2, for a temperature of 700°C is estimated to be between 10−18 and 10−12. Tin mineralization is connected with the igneous rocks and the relationship of tin in the micas to the rock compositions is described and the factors controlling the distribution of tin are discussed. The biotites have only up to 21 % of the tin of the granites. In general Sn increases in the biotites with decreasing temperature of equilibration and with increase in the degree of albitization of the granites. High Sn in biotites seems to be an indicator of potential mineralization.

AbstractThis article discusses the relationship of Tacitus to his younger contemporary Suetonius, challenging the view that Suetonius wrote a ‘supplement’ to the historian. Scholarly focus on this pair has led to the widespread belief that Suetonius had read Tacitus’Annals,which is unsupported by the evidence. The prevailing consensus that the biographer may at times be subtly criticizing the historian persists in commentaries on Suetonius’Caesars.It is argued that where their two accounts appear to meet, Suetonius is better seen as responding to the earlier common source or sources, or distinguishing himself from the conventions of historiography at large.
