A SEM Study Of Copper Corrosion In Bowling Green Supply LinesAlghamdi, Reema M 01 October 2015 (has links)
Recently, the rate of corrosion of copper water pipes in Bowling Green, Kentucky has unexpectedly accelerated. The specific reasons for this are unknown. Our aim is to elucidate the factors enhancing the corrosion and help understand the primary mechanisms of action. This will help in combating and reducing future corrosion incidents leading to pipe failure, thus reducing losses experienced when these pipes are replaced. This study seeks to explore the characteristics and factors involved. The scanning electron microscopy was used to obtain elemental composition, and images of both inside and outside of the corroded pipes. Strikingly, corrosion primarily occurred on the outside of the pipes, not inside. X-ray crystallography also was used to examine the pipes. The results showed that the interior of the pipes mostly consisted of SiO2, CuO2, CaCO3 while the exterior consisted of Cu2(OH)2CO3, Fe2Al2O4, CaCO3, SiO2 and Cu2O. There was no clear single factor for the corrosion observed. For further studies, we plan to long temporal experiments. The results from the study will help in minimizing the costs to the city in Bowling Green, Kentucky.

Spermatological characters in Bothriocephalidea (Cestoda) / Spermatological characters in Bothriocephalidea (Cestoda)ŠÍPKOVÁ, Lenka January 2011 (has links)
Spermiogenesis and ultrastructure of the spermatozoon of two bothriocephalidean cestodes, Oncodiscus sauridae and Senga sp., have been studied using transmission electron microscopy. The presence of a classical pattern for spermatological characters (spermiogenesis of type I with dense-material in early stages and sperm of type II with a characteristic ring of cortical microtubules in the anterior part) in Bothriocephalidea is discussed.

Demonstration of intracellular glycogen, peroxidases and viruses by light and electron microscopyTiedt, Friedrich AC January 1995 (has links)
Thesis (Masters Diploma (Medical Technology)--Cape Technikon, Cape Town, 1995 / The objective of the present study vvas primarily to determine
vvhether modifications to the existing osmium
tetroxide/potassium ferrocyanide method could be used as a
general ultrastructural glycogen stain and whether this
glycogen, vvhen so contrasted, differed in appearance in
different tumours, such as Evving's sarcoma,
Leiomyosarcoma, Rhabdomyosarcoma and Hepatocellular
carcinoma. Normal skeletal muscle and liver were used to
obtain a standard for the appearance of glycogen, and then,
with diagnostic criteria in mind, the four glycogen-rich
tumours, mentioned above vvere examined to determine the
appearance, distribution and amount of glycogen present in
them.
Modifications to the osmium tetroxide/potassium
ferrocyanide (OPF) method consisted of raising the
concentration of the ferrocyanide, and using no en bloc or
thin section staining by any uranyl salt solutions, because
solutions of uranyl salts leaches glycogen from tissue. This
procedure resulted in extremely electron-dense intracellular
glycogen being retained, vvhich aided diagnosis of the these
tumours. At high magnification. (>X30000) there vvas no
morphological difference betvveen the glycogen particles in
the various tumours, so these particles as such could not be
used as a diagnostic criterion.
Existing methods for the demonstration of myeloperoxidase
and platelet peroxidase vvere modified to obtain more precise
localization of the diaminobenzidine (DAB) reaction product.
Different anti-coagulants, one of which was heparin and a
modified fixation procedure vvas follovved.
