Although several U.S. and European airlines have started providing human factors training to their maintenance personnel, the academic community (some 300 academic programs in the United States and several others in Europe and Asia) has not yet started offering formal human factors education to maintenance students. The highly respected authors strongly believe in incorporating the human factors principles in aviation maintenance. This is the first of two volumes providing effective behavioural guidance on risk management in aviation maintenance for both the novice and the experienced maintenance personnel. Its practical guidelines assist both student and practising aviation maintenance personnel to develop sustainable safety culture. For the maintenance community it provides some theoretical discussion about the "Why?" for risk management and then focus on the 'How?' to implement a successful error reduction program. To help the maintenance community in making a strong case to their financial managers, the authors also discuss the return on investment for risk management programs. The issue of risk management is taken at two levels. First, it provides a basic awareness information to those who have little or no knowledge of maintenance human factors. Second, it provides a set of practical tools for the more experienced people so that they can be more effective in risk management and error recovery in their jobs. This invaluable book serves as a practical guide as well as an academic textbook. The book covers fundamental human factors principles from a risk management perspective. Upon reading this informative book, the audience will be able to apply the basic principles of risk management to aviation maintenance environment, and they will be able to use low-risk behaviours in their daily work.

Considering the global awareness of human performance issues affecting maintenance personnel, there is enough evidence in the US ASRS reports to establish that systemic problems such as impractical maintenance procedures, inadequate training, and the safety versus profit challenge continue to contribute toward latent failures. Manoj S. Patankar and James C. Taylor strongly believe in incorporating the human factors principles in aviation maintenance. In this, their second of two volumes, they place particular emphasis on applying human factors principles in a book intended to serve as a practical guide, as well as an academic text. Features include: - A real 'how to' approach that serves as a companion to the previous volume: 'Risk Management and Error Reduction in Aviation Maintenance'. - Self-reports of maintenance errors used throughout to illustrate the systemic susceptibility for errors as well as to discuss corresponding solutions. - Two tools - a pre-task scorecard and a post-task scorecard - introduced as means to measure individual as well as organizational safety performance. - Interpersonal trust and professionalism explored in detail. - Ethical and procedural issues associated with collection and analysis of both qualitative as well as quantitative safety data discussed. The intended readership includes aviation maintenance personnel, e.g. FAA-type aircraft mechanics, CAA-type aircraft maintenance engineers, maintenance managers, regulators, and aviation students.

Advances in Chemistry Research. Volume 48 opens with a discussion of statistically significant evidence of the application of stochastic dynamics, in particular, the BoxMullers method, for studying the temporal behavior of the mass spectrometric intensity. The presented model equations, based on stochastic dynamics, are validated using another source of evidence of mass spectrometric diffusion parameters called the current monitoring method. Crystallographic data of five of the studied crystals are presented for first time together with an electron density analysis.

The various techniques employed for this purpose are discussed. The following chapter presents methods of the stereoselective C-acylation and their applications in natural product synthesis. Compared to stereoselective aldol reactions, stereoselective acylation reactions are not frequently used but are still important methods because they are irreversible reactions, while some aldol adducts undergo the retro-aldol reaction. In the concluding section, the authors discuss their recent progress in developing Ir complex-catalyzed N-alkylation systems employing alcohols as alkylating reagents.

In the introductory chapter of Advances in Chemistry Research. Volume 47, the authors review eterogeneous catalytic systems reported from 2004 to 2018 for some of the key chemical transformations of limonene such as oxidation, hydrogenation and isomerization reactions. The main advantages of the heterogeneous catalytic processes are the easy separation of a catalyst from a reaction mixture, the possibility of reuse and the mild reaction conditions of the processes. The processes responsible for the memory effect (induced by electrical breakdown and discharge in custom-made/commercial tubes) filled with noble gases at low pressure are analyzed in the next chapter. This analysis is based on the experimental results pertaining to a mean value of electrical breakdown time delay as a function of the afterglow period. Next, a variety of hydroxyquinoline-based compounds from three perspectives, namely their applications as anticancer agents, as sensing agents for metal detection, and the mechanisms of their actions. The authors provide an overview on the ruthenium(II) polypyridyl complexes catalyzed and visible-light assisted procedures employed for the production of radical intermediates from sulfonyl chlorides. In addition, they account the applications of these radical species in the syntheses of functionalized aliphatic and aromatic compounds. Because previous kinetic models assume that the reaction medium was reacting at random and without a turnover associated to thermodynamics exchanges, some included experimental studies aim to show that coupling factor 1 from spinach chloroplasts has latent ATPase activity which becomes expressed after heat-treatment and incubation with calcium. Lastly, optically active ketones are isolated from the domino deprotection/decarboxylation/protonation reaction of racemic allyl or benzyl B-ketoesters and corresponding enol carbonates mediated with both palladium species and unichiral aminoalcohols. Protonation of an ammonium enolate as the key enantioselective step is consistent with the absence of a relationship between the nature of the substrate and the absolute configuration of the isolated ketone.

This is a verse-by-verse commentary on the Book of Revelation presented from a Post-tribulation Rapture point-of-view. It includes discussion of who John was that received the Revelation, the probable time in which it was received and written, a look at possible interpretations of the meaning and purpose of the Revelation, and other issues related to this magnificent, symbolic work. In this presentation, the main body of the Revelation is shown as a series of Seven Visions - each with its own story to tell, and each ending with the Return of the Lord or an event heralding that Return - Seven Visions all rolled into one great, glorious truth given on the Isle of Patmos to John by Jesus Christ.
