A new method for determining the vitrification rate of pottery depending on the firing temperature was devised using secondary electron images (SEI) of scanning electron microscope (SEM). Several tests were performed to establish the appropriate operating conditions of SEM and reproducibility as well as to examine the applicability of the method. The grayscale values converted from each pixel o...

Changes in temperature of up to several degrees have been reported in different brain regions during various behaviors or in response to environmental stimuli. We investigated temperature sensitivity of dopaminergic neurons of the rat substantia nigra pars compacta (SNc), an area important for motor and emotional control, using a combination of electrophysiological techniques, microfluorometry ...

Key aspect of this work is the investigation of local Al contacts with regard to void formation under a non-uniform temperature of the solar cell during the firing process in the belt furnace. The impact on electrical properties is determined by IV measurements and electroluminescence imaging (EL). Scanning acoustic microscope (SAM) measurements on full cell area are used for a spatially resolv...

Introduction: Success in anesthesia administration relieves the perception of pain during surgery. Lidocaine is the most commonly used local anesthetic agent in clinical medicine. Moreover, anesthetic agents' temperature changes can influence cell membrane permeability. Here, the effectiveness of different temperatures of lidocaine (Lid.) on anesthesia success rate in rats has been investigated...

Firing is a crucial step in the production of pottery, as it irreversibly transforms clay into ceramic. Clay sintering and subsequent vitrification occur during firing, together with other transformations undergone by specific minerals rock inclusions according to their optical physical properties, including colour. Some these are visible thin-sections might be interpreted technological markers...

Porcelain enamel is an inorganic-type coating, which applied to metals or glass for both decorative and functional purposes. This coating a silica-based solidified mass obtained by high-temperature firing (temperature can range between 450 1200 °C depending on the substrate). coatings differ from ceramic mainly their structure dilatation coefficient, organic paints inorganic nature of matrix ch...

This paper reports a comparative study of burning Thai rice husk, sunflower shells and fine rubberwood sawdust as well as co-firing of the sawdust and shredded eucalyptus bark in the swirling fluidizedbed combustor (SFBC). All experiments for firing individual fuels were performed for the combustor heat input of ∼300 kWth. However, in the co-firing tests, the fuel mixture was delivered at a fix...

Many species of cold-blooded animals experience substantial and rapid fluctuations in body temperature. Because biological processes are differentially temperature dependent, it is difficult to understand how physiological processes in such animals can be temperature robust [1-8]. Experiments have shown that core neural circuits, such as the pyloric circuit of the crab stomatogastric ganglion (...
