The control of the heating curve to manipulate microstructure during sintering is a way that has being studied and it presents advantages such as simplicity and economy. In this work, it was studied the sintering in two-steps of a commercial ultrafine alumina. For this, the alumina power was deagglomerated in milling ball and the specimens for sintering were pressed. Sintering was performed in a dilatometer, with constant heating rate of 15°C/min up to 1500°C. By these results, heat treatment temperatures for two-step sintering were defined. The sintering specimens were characterized through the apparent density measures using Archimedes method, the grain size measures using image analysis program and microstructural analysis using a scanning electron microscope. The results showed that the two-step sintering influence in the development of the final microstructure and permit the control of the grain size and density.

Reliability Estimates

A method to determine body measurements by computer image analysis of lamb photographs was described by Komlosi (1994). It was suggested that the technique could be used to predict conformation of live sheep, particularly candidate breeding rams. This study was conducted to evaluate the reliability of lamb body measurements derived using this technique.Thirty lambs (Border Leicester (4), Texel (16), Suffolk (10)) were used. Reliability estimates were obtained from repeated (5 replications) photographs of the same animals and from repeated measurements (4 replications) of individual photographs. Eight lamb body measurements were used in this study namely, body length (BL), height at withers (HW), height at hip (HHP), hind-quarter horizontal distance (HQH), hind-quarter diagonal distance (HQD), hind quarter area (HQA), side area (SA) and rump diagonal (RUD). These measurements are as described by Komlosi (1994).

One area of research at Georgia Tech recently has focused on the measurement of Card-web density. This research is part of a study to spin yarns directly from a card web thus eliminating several processes. A Card-Spinning system has been designed which can quantify the cross-machine and machine direction web non-uniformity using a non-contact web density measurement technique. The web monitoring system for Card-Spinning uses a line scan camera to capture the image continuously and is equipped with an image analysis program, to characterize the web quantitatively, predicting the product quality. A multifunctional graphical interface has been designed for the image analysis program, which can be used to calculate the statistics for the non-uniformity of the card web both online and offline. This would help in characterizing the nature of non-uniformity and to understand the system better before employing methods to improve it. This paper discusses the development and results from the work.

We studied integrins involved in the adhesion of resting and activated megakaryocytes (MK) to fibronectin (FN) and fibrinogen (FGN). Guinea pig MK were isolated and in some experiments were activated by thrombin. MK adhering to FN or FGN coated on coverslips were quantitated by a computerized image analysis program. The binding of soluble human FN to MK was detected by Western blotting. Anti-integrin antibodies, disintegrins, and cyclic RGD peptides were used to identify integrins involved in the adhesion of MK to FN or FGN. Resting MK adhered to coverslips with immobilized FN. The adhesion of MK to FN was primarily inhibited by an anti-5 antibody and EMF-10, a distintegrin highly specific for 5β1. However, the adhesion of MK to FN was not blocked by agents that inhibit ΙΙbβ3, vβ3 or 4β1. A β1 activating antibody increased the number of MK bound to FN due to the activation of 5β1. The binding of soluble FN was also primarily inhibited by agents that block 5β1. Resting MK did not adhere to FGN. However, MK activated by thrombin did adhere to FGN. This binding was mediated by ΙΙbβ3, because binding was inhibited by bitistatin, a disintegrin, and a cyclic RGD peptide that are known to block this integrin. The binding of thrombin-activated MK to FN was mediated by both 5β1 and ΙΙbβ3 based on the additive effect of agents that inhibit these integrins. The study indicates that resting MK bind to FN but not to FGN and that 5β1 is the major integrin involved in the binding of MK to FN. Activated MK bind to FGN primarily by IIbβ3. However, the binding of activated MK to FN is due to both 5β1 and IIbβ3. The demonstration that 5β1 and that IIbβ3 are involved in MK adhesion indicates that these integrins may have a role in MK maturation and platelet production. © 1998 by The American Society of Hematology.
