Southern New England

In southern New England, typological distinctions between Niantic, Hackney Pond, and Shantok ceramics have been used to describe changing settlement patterns for the Late Woodland (500- 350 Years B.P.) and contact (post-A.D. 1600) periods. Based on the initial typologies developed by Rouse (1947) the Shantok ceramic tradition was also considered an ethnic marker of the Mohegan and Pequot tribes based on material recovered from Fort Shantok. Reexamination of stylistic data have suggested that levels of stylistic similarity between late ceramic types actually limit their use as ethnic markers in reconstructing contact period settlement patterns (Lizee 1994; McBride 1990). In this study, neutron activation analysis is employed to determine if compositional profiles correspond with identified stylistic types. The distribution of compositional groups within the region proves to be useful in describing changes in settlement during the Late Woodland and contact periods for southeastern Connecticut. Results of this study suggest that cultural factors underlying the evolution of the historic Pequot and Mohegan tribes, and locations of focal village sites, also had an impact on access to clay resource zones at the time of European contact.

Background: Thyroid cancer is an internationally important health problem. The aim of this exploratory study was to evaluate whether significant changes in the thyroid tissue levels of Ag, Co, Cr, Fe, Hg, Rb, Sb, Sc, Se, and Zn exist in the malignantly transformed thyroid. Methods: Thyroid tissue levels of ten trace elements were prospectively evaluated in 41 patients with thyroid malignant tumors and 105 healthy inhabitants. Measurements were performed using non-destructive instrumental neutron activation analysis with high resolution spectrometry of long-lived radionuclides. Tissue samples were divided into two portions. One was used for morphological study while the other was intended for trace element analysis. Results: It was found that contents of Ag, Co, Cr, Hg, and Rb were significantly higher (approximately 12.8, 1.4, 1.6, 19.6, and 1.7 times, respectively) in cancerous tissues than in normal tissues. Conclusions: There are considerable changes in trace element contents in the malignantly transformed tissue of thyroid.

A study was undertaken to evaluate the inorganic elements for humans in two Indian medicinal plants leaves, namely Sphaeranthus indicus, and Cassia fistula by Instrumental Neutron Activation Analysis (INAA). INAA experiment was performed by using 20 kW KAMINI Reactor at Indira Gandhi Centre for Atomic Research (IGCAR), Kalpakkam. The emitted gamma rays were measured using gamma ray spectrometer. The concentrations of Al, Br, Ca, Fe, K, La, Mg, Mn, Na, Sc, V and Zn were determined in the selected medicinal plants. The medicinal leaves are using in treatment of various important ailments. The elemental content in selected medicinal leaves is various proportions depending on the soil composition, location of plant specimen and the climate in which the plant grows.
