to understand the rate of oxidation of sponge irons and its mechanisim, their physical and chemical properties are normally required. in this report attempt has been made to show the results of research on varius pellets and briqutts produced at ahwaz steel complex. in presenting these data, the rate of oxidation of these articles in air between 300 and 600 °c is also quotted and analysed. in a...

We study subgroups of Z which possess group theoretic properties analogous to properties introduced by Menger (1924), Hurewicz (1925), Rothberger (1938), and Scheepers (1996). We obtain purely combinatorial characterizations of these properties, and combine them with other techniques to solve several questions of Babinkostova, Kočinac, and Scheepers. We also show that, while the Menger Conjectu...

We study subgroups of Z which possess group theoretic properties analogous to properties introduced by Menger (1924), Hurewicz (1925), Rothberger (1938), and Scheepers (1996). The studied properties were introduced independently by Kočinac and Okunev. We obtain purely combinatorial characterizations of these properties, and combine them with other techniques to solve several questions of Babink...

The main goal of this paper is to present an alternative, real variable proof of the T(1)-Theorem for the Cauchy Integral. We then prove that the estimate from below of analytic capacity in terms of total Menger curvature is a direct consequence of the T(1)-Theorem. An example shows that the L 1-BMO estimate for the Cauchy Integral does not follow from L 2 boundedness when the underlying measur...

in this research, a novel formulation of sponge cake was studied. instant tea powder (itp) with high ester-catechins content was used to replace 0, 7.5, 12.5, and 17.5% of flour to make sponge cakes, hereafter referred to as the control, itp1, itp2, and itp3, respectively. the microbiological analysis and lipid oxidation experiments were conducted and the odor, flavor, color, chewiness, and ove...

The aim of this study was to determine the rheological properties of sponge cake batters andphysical (volume, density, moisture content, weight after baking and color) and sensory properties of spongecake formulated with four different levels of wild sage seed gum (0, 0.5, 0.75 and 1.0 %). Sponge cake battersformulated with gums showed pseudoplastic (shear-thinning) and thixotropic (time-depend...

Microbes associated with marine sponges play significant roles in host physiology. Remarkable levels of microbial diversity have been observed in sponges worldwide through both culture-dependent and culture-independent studies. Most studies have focused on the structure of the bacterial communities in sponges and have involved sponges sampled from shallow waters. Here, we used pyrosequencing of...

The boring sponge Cliona celata is a nuisance species that can have deleterious effects on eastern oyster Crassostrea virginica growth, condition, and survival. Surprisingly, however, these effects have not been well documented and when examined, results have been equi-vocal. In this study, we provide a direct comparison of growth, condition, and survival of sponge-colonized and uncolonized oys...

OBJECTIVES To investigate the stain removal ability of melamine sponge before aesthetic tooth whitening in extracted teeth. METHODS Melamine sponge of thickness 40 mm was compressed and the destruction of the partition wall structure during the compression process was examined under a stereoscopic microscope. An extracted human tooth was cleaned by normal polishing or with melamine sponge for...
