En la actualidad, la pornografia se encuentra en un completo desenfreno. Los hombres estan siendo constantemente expuestos a mujeres parcialmente vestidas, escenas con sexo explicito y conversaciones eroticas y excitantes. Todo esto hace arder el fuego de las pasiones y deseos del hombre, transportando sus pensamientos a un mundo irreal y repleto de fantasias con actividades sexuales ilicitas. Frente a esto surge la pregunta: Acaso el hombre podra ser victorioso al enfrentar tales tentaciones? Aprende junto a nosotros el plan de Dios para la abstinencia de la inmoralidad sexual, fisica y mental. Pornography today is rampant. Men are constantly being exposed to partially dressed women, lovemaking scenes, and stimulating conversations. All of these fuel the fire of a man's passions and desires, leading his thoughts to a fantasy world of illicit sexual activity. Can he be victorious over such temptations? Learn God's plan for abstaining from sexual immorality, physically and mentally.
Theory of Nonlinear Propagation of High Harmonics Generated in a Gaseous Medium establishes the theoretical tools to study High-Order Harmonic Generation (HHG) by intense ultrafast infrared lasers in atoms and molecules. The macroscopic propagation of both laser and high-harmonic fields is taken into account by solving Maxwell's wave equations, while the single-atom or single-molecule response is treated with a quantitative rescattering theory by solving the time-dependent Schrodinger equation.
This book demonstrates for the first time that observed experimental HHG spectra of atoms and molecules can be accurately reproduced theoretically when precise experimental conditions are known. The macroscopic HHG can be expressed as a product of a macroscopic wave packet and a photorecombination cross section, where the former depends on laser and experimental conditions while the latter is the property of target atoms or molecules. The factorization makes it possible to retrieve microscopically atomic or molecular structure information from the measured macroscopic HHG spectra.
This book also investigates other important issues about HHG, such as contributions from multiple molecular orbitals, the minimum in the HHG spectrum, the spatial mode of laser beams, and the generation of an isolated attosecond pulse. Additionally, this book presents the photoelectron angular distribution of aligned molecules ionized by the HHG light.
The four companion volumes on Dynamic Aspects of Detonations and Explosion Phenomena and Dynamics of Gaseous and Heterogeneous Combustion and Reactive Systems present 111 of the 230 papers given at the Thirteenth International Colloquium on the Dynamics of Explosions and Reactive Systems held in Nagoya, Japan. These books embrace the topics of explosions, detonations, shock phenomena, and reactive flow, as well as the gasdynamic aspects of nonsteady flow in combustion systems, the fluid mechanics aspects of combustion, and diagnostic techniques. Two of the volumes, Dynamics of Gaseous Combustion (Vol. 151) and Dynamics of Heterogeneous Combustion and Reacting Systems (Vol. 152), focus on the processes of coupling the exothermic energy release with the fluid mechanics occurring in various combination processes. The other two volumes, Dynamic Aspects of Detonations (Vol. 153) and Dynamic Aspects of Explosion Phenomena (Vol. 154), address the rate processes of energy deposition in a compressible medium and the concurrent nonsteady flow as it typically occurs in explosion phenomena.
