Inductively Coupled Plasma-Optical Emission Spectrometry
ISBN: 9783659439186 / Angielski / Miękka / 2013 / 80 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The book is intended as that introduction to the ICP-OES technique. It was written not only for those persons who have some familiarity with other analytical techniques such as atomic absorption spectrometry but also for novices in the field of analytical chemistry. The book begins with some simple, yet fundamental, concepts regarding atomic spectroscopy and the analytical techniques based on this field of study. As one progresses through the book, more detail regarding the ICP-OES technique is presented including information about ICP-OES performance, instrumentation and methodology. We...

Fundamentals of Gas Proportional Counter
ISBN: 9783659390920 / Angielski / Miękka / 2013 / 76 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. This book represents deep ideas about equipment used mainly to detect the radioactivity and presence of the radioactive isotopes in the different products consumed by human. This equipment is called as Gas Proportional Counter. The central laboratories which are responsible of analysis of these products contain this equipment. The analysts who use this technique cannot solve some problems due to complications in some details about the instrument. So, we tried to show some of these details to provide the undergraduate students in the scientific colleges with some Knowledge about detection of...

Concepts and Theories of Chromatography
ISBN: 9783659433320 / Angielski / Miękka / 2013 / 104 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The book shows principles and applications of the most distributed technique used for water analysis. The central laboratory of Greater Cairo Drinking Water Company (GCWC) uses this important technique and applies the analytical methods recorded in the standard methods for water and wastewater examination. This laboratory represents nucleus and origin of many reference laboratories of water analysis in Egypt. Wael Mahmoud and his team of the researchers modified the scientific cooperation between the central laboratory of GCWC and the national research centre. Wael and his team used the...

Controlled Release Injection of a Central Nervous System Acting Drug
ISBN: 9783659633386 / Angielski / Miękka / 2014 / 292 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Alzheimers disease is a chronic, progressive, neurodegenerative disorder of the brain characterized by deficits in memory and cognitive function. Donepezil is a reversible, noncompetitive cholinesterase inhibitor. It has a high binding specificity for brain acetylcholinesterase, with little to no affinity for butyrylcholinesterase. It is approved by the FDA for the treatment of severe Alzheimers disease. The aim of this work is to formulate depot injection lipospheres and in situ implants containing Donepezil for treatment of Alzheimer disease in order to decrease dosing frequency and...

Cationic Surfactants as Corrosion Inhibitors under H2S environment
ISBN: 9783659665547 / Angielski / Miękka / 2014 / 112 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. The use of chemical inhibitors to decrease the rate of corrosion processes is quite varied. In the oil extraction and processing industries, inhibitors have always been considered to be the first line of defense against corrosion. A great number of scientific studies have been devoted to the subject of corrosion inhibitors.Cationic surfactants represent only 5-6% of the total surfactant production. However they are extremely useful for some specific uses, because of their peculiar properties .They are not good detergents nor foaming agents, and they cannot be mixed in formulations which...

Natural Killer Cells Phenotype and Hepatitis C Virus Infection
ISBN: 9783659788031 / Angielski / Miękka / 2015 / 136 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. During the early phases of a hepatitis C virus (HCV) infection, natural killer (NK) cells activation appears to be critical in the innate immune responses that have the potential of clearing the infection. Impaired activity of NK cells has been proposed as a mechanism contributing to viral persistence and chronic infection in HCV infection. We aim to assess the impact of HCV infections on NK cells regarding frequency, and subset distribution. The correlation between the phenotype of NK subsets and the various stages was assayed. Number of total NK cells was significantly reduced and a...

Beneficial Role Of Surfactants in Petroleum Applications
ISBN: 9783659803574 / Angielski / Miękka / 2015 / 112 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych. Surface-active agents, surfactants, are widely used and find a very large number of applications in the petroleum industry. This is attributed to their remarkable ability to influence the properties of surfaces and interfaces. Recently, one of the most important applications of surfactants is as effective corrosion inhibitors in the oil industry One of the major consumers of corrosion inhibitors is the oil industry, where they are employed to reduce the corrosion rate of different types of steel alloys in gas and oil well equipment. Both general and localized corrosion are encountered in this...
