Development of Fashion Color Analysis Program Useful for Fashion Image Analysis

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.

This protocol outlines a method of quantitatively measuring the degree of bleaching of a coral colony non-destructively in the field using image analysis. Previous studies have shown that mean intensity grey (MIG), also known as percent whiteness, is highly correlated with chlorophyll a and Symbiodiniaceae density (Chow et al. 2016, Amid et al. 2018), and therefore can be used to quantify the bleaching intensity of a coral colony. Color analysis can be done using digital photographs of live coral colonies either in situ (e.g., Maguire et al. 2003) or ex-situ in the lab (Amid et al. 2018; this protocol). Photographs must be taken prior to any preservation or processing of tissue, such as freezing, use of preservatives or fixatives, airbrushing etc., to ensure no alteration of the original coral color occurs. In this protocol, corals are photographed in front of a white reference standard and the resulting color images are subsequently converted to 8-bit greyscale and analyzed. There are two steps to this protocol: 1) Photographing live coral fragments 2) Image analysis of mean grey value This protocol was written by Dr. Rowan McLachlan and was reviewed by Dr. Andréa Grottoli. Acknowledgments I would like to thank Dr. Eugene Katrukha for kindly taking the time to teach me this method, and providing me feedback on how to produce higher quality images for analysis.

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.

Corn Plants

Sweet corn (Zea mays L.) yields in the Willamette Valley of Oregon declined during the 1990s. Severe root rot affected some plants shortly before harvest, but was absent in other plants that showed secondary symptoms of reduced ear yield and leaf death; necrosis of stalk nodes and crown tissues was found instead. Studies were done to determine if there is a relationship among yield and necrosis of crowns, stalk nodes, nodal roots, radicles, or sub-crown internodes. An image analysis program was used to quantify the grayscale value of crown and node tissues. Regression analysis indicates that plants with darker crown tissues have lower ear weights. Rots of the nodal roots, radicle, or sub-crown internode were poor predictors of ear weight at harvest. When either Fusarium oxysporum or F. verticillioides were isolated from crowns of commercial sweet corn plants, these crowns had significantly darker grayscale values than those from which neither species was isolated; ear weights were also lower when F. oxysporum was isolated from the crown or a stalk node.
