suppression of coke formation in thermal cracking by coke inhibitors
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولThe Use of Metallurgical Coke as Carburizing Material in the Foundry
Original scientific paper The properties of metallurgical cokes obtained in a laboratory from pure coal and with additives (light atmospheric residue of oil distillation and coal tar pitch) after heat treatment to 1600 °C were investigated. Changes in the basic characteristics (density, moisture, ash, metal and sulphur contents) were examined. Crystallographic parameters (crystallite size, Lc a...

This article defines the concept of relocating the program part of a finite partial state of SCM (data part stays intact). The relocated program differs from the original program in that all jump instructions are adjusted by the relocation factor and other instructions remain unchanged. The main theorem states that if a program computes a function then the relocated program computes the same fu...
متن کاملMetallurgical effects on titanium by laser welding on dental stone.
It is not known for certain that dental stone components influence titanium welding. In this study, we investigated metallurgical problems caused by laser welding on dental stones using wrought commercial pure (CP) titanium. A pulsed Nd:YAG laser irradiated a number of specimens' surfaces which were fixed on either a dental hard stone or a titanium plate. The metallurgical properties of the wel...

A sentinel node biopsy (SNB) has been proved to be an accurate method to estimate the axillary lymph node status as a replacement for axillary lymph node dissection (AxLND) in patients with early breast cancer who have not been treated with neoadjuvant chemotherapy (NAC). We examined the feasibility and accuracy of performing SNB after NAC. Seventy breast cancer patients treated with NAC were e...
