In Riedel’s thyroiditis, a rare chronic inflammatory disease of thyroid gland, fine needle aspiration is usually non-diagnostic because most often only follicular cells are obtained and not the fibrous material characteristic of this type of thyroiditis. Therefore the diagnosis is often only established by histopathologic study of the surgically obtained biopsy. The illustrated case is a 46-yea...

Festuca L. comprises perennial herbs and about 450 species. It belongs to the tribe Poeae R. Br. (= Festucaceae Dumort), subfamily Pooideae of Poaceae. These species are different in leaf size, life duration and lamina width. The genus is divided into two groups based on lamina width: fine-leaved and broad-leaved. In this study, leaf anatomy of F. akhanii, F. elwendiana,F. heterophylla, F. sulc...

Ione Fine is a Professor of Psychology at the University of Washington in Seattle, USA. She studied Experimental Psychology and Philosophy at Oxford, and did her PhD with Robert Jacobs at Rochester, NY. She then fell in love with a Californian, so she moved to the University of California, San Diego to do a post-doc with Donald MacLeod and Karen Dobkins. After a brief spell at Second Sight Medi...

This paper evaluates attitudes of Iranians toward crossing red traffic lights and their sensitivity to fines. Economic theory of crime under expected utility predicts that because of the possibility of severe punishments, risk adverse individuals would not cross red lights. This is implied by the Becker proposition. However, among 262 individuals surveyed, more than half of the sample has previ...

To study the effect of different substrates on growth and yield of gerbera, this experiment was carried out as randomized completely block design with 14 treatments and 3 replications. Treatments were as fallowing: fine sand, peat+fine sand (25%+75%), peat+fine sand (50%+50%), perlite+peat (75%+25%), perlite+peat (50%+50%), perlite+peat (25% +75%), perlite+peat+expanded clay (25%+70%+5%), perli...

Application of gravity and magnetic separation methods to upgrade low grade Manganese ores from Venaj Mine has been reported elsewhere. This paper discusses the results of flotation tests, as well as combination of flotation and magnetic method to concentrate fine particles (less than 150 microns) of manganese ore. Results obtained from various direct and reverse flotation tests, using differen...

The main purpose of this paper is to determine the fine spectrum of the generalized upper triangular double-band matrices uv over the sequence spaces c0 and c. These results are more general than the spectrum of upper triangular double-band matrices of Karakaya and Altun[V. Karakaya, M. Altun, Fine spectra of upper triangular doubleband matrices, Journal of Computational and Applied Mathematics...
