Description:

Here’s an essential reference for anyone needing an advanced understanding of the nature and treatment of hypertension. Dr. Laragh, a pioneering clinician and scientist, demonstrates the central role of an overactive renin system for causing most hypertension. In his new book, Dr. Laragh discusses his research and its relevance to caring for everything from asymptomatic patients to hypertensive emergencies. And, he provides visit-by-visit details of his new pathophysiologically and biochemically guided treatment. The result of his work is a specific approach that makes it possible to more effectively prevent, arrest, and treat hypertension and its consequences–including congestive heart failure, myocardial infarction, kidney failure and stroke.

Description:

The thesis deals with theoretical description of the coherent interaction of polychro-matic light with multilevel atom within the hyperfine structure of the D1 transition in so-dium and rubidium atoms. Special attention is paid to the case of cold atoms. Our theoreti-cal treatment for the time evolution of the dressed atom is based entirely upon the density matrix approach. Propagating radiation fields are described by the reduced Maxwell’s field equations. Such a general formalism will enable us to reveal an enhancement of nonlinear-ity taking into account all the accessible multipoles of the density matrix. Thus we are able to show effects such as electromagnetically induced emission and the multiple light storage effect. We have exploited multiple light storage effect in order to obtain fast soliton train propagation in cold rubidium atoms. In addition, we have attempted to describe the space dependent group velocity and the delay/advancement of the light pulses. Finally, classical and quantum arrival-time distributions are discussed through the fast and slow light propa-gation in coherently prepared gaseous media. We have constrained ourselves to describe these effects in terms of the same set of equations, without approximations, while incorpo-rating homogeneous atomic relaxations. Throughout our thesis, we are motivated by the recent development in the fields of nonlinear optics and quantum information processing. Out of a variety of those modern spectroscopic techniques, we are going to mention briefly the discovery of dark resonance lines, oscillation without population inversion, coherent population trapping, electromagnetically induced transparency, electromagnetically in-duced absorption, light storage effect, slowing down of the group velocity of light, quan-tum switching effect, and three-photon electromagnetically induced transparency. These effects will assist us in controlling the group velocity of light and developing optical mem-ory devices as well as optical switches.
The thesis comprises of seven chapters. Mainly, we are interested in the coherent inter-action of light with the D1 line of alkali-atoms including the hyperfine structure. In brief, there are four dipole-allowed transitions. Chapter 1 describes stationary interaction of line-arly polarized light with sodium atom. It introduces the rotationally irreducible tensors for different ranks that are relevant to the D1 symmetry as well as its notations. Chapter 2 deals with the coherent interaction of two stationary beams as well as two pulsed fields where
the atom is described by the same basis tensors found in Chapter 1. Chapter 3 is devoted to the triple-colour excitation. Chapter 4 deals with the case when the light is amplitude or phase modulated. Chapter 5 reports a technique to produce advanced soliton train thought
a triple excitation. Chapter 6 assesses attempts to describe classical and quantum arrival-time distributions for pulsed dual-colour excitation. Finally Chapter 7 summarizes the the-sis and displays the conclusions. The thesis detailed layout is described as follows.

Description:

Gdynia to port, a port to Gdynia. Tak na początku istnienia II Rzeczpospolitej ukształtowała się jej morska stolica. Monografia Anny Orchowskiej to pierwsza publikacja poświęcona całokształtowi jednej z największych realizacji międzywojnia. Realizacji, która nie tylko pełniła istotne funkcje gospodarcze, ale też szybko stała się wizytówką kraju. Zwrócone niejako frontem do morza budynki były awangardowe i śmiałe w formie. Budowane w duchu modernizmu, doskonale wpisywały się w światowe trendy lat dwudziestych i trzydziestych XX wieku. Autorka – jako architekt i historyk architektury – analizuje jakość zastosowanych w porcie rozwiązań zarówno estetycznych, jak i technicznych i technologicznych. Nie pomija także czynnika ludzkiego. Port nie powstałby przecież bez inicjatorów i organizatorów morskich przedsięwzięć, projektantów, inżynierów, budowniczych, a wreszcie – bez zwykłych pracowników. Czy udało im się stworzyć dzieło ponadczasowe?

Description:

A Popular History of Astronomy During the Nineteenth Century (Fourth Edition) by Agnes M. Clerke is a comprehensive and engaging chronicle of the remarkable advancements in astronomy throughout the 1800s. Written in accessible language for the general reader, the book traces the evolution of astronomical thought and discovery, highlighting the pivotal figures, groundbreaking observations, and technological innovations that shaped the field during this transformative era. Clerke delves into the achievements of astronomers such as William Herschel, Friedrich Bessel, John Herschel, and many others, illustrating how their work expanded humanity’s understanding of the universe. The narrative covers a wide range of topics, including the development of telescopic observation, the discovery of new planets and minor bodies, the study of comets and meteors, and the emergence of astrophysics as a scientific discipline. Clerke also explores the impact of photography and spectroscopy on astronomical research, revealing how these tools revolutionized the study of stars, nebulae, and the structure of the Milky Way. The book provides detailed accounts of major observatories and the international collaborations that propelled astronomy forward. Throughout, Clerke’s writing is informed by her deep knowledge and passion for the subject, making complex scientific concepts accessible and fascinating. The fourth edition incorporates the latest discoveries and research up to the late nineteenth century, offering readers a thorough and vivid portrait of a century that forever changed our view of the cosmos. This work remains a valuable resource for anyone interested in the history of science, the development of astronomical techniques, and the enduring quest to understand the universe.

It’s just another Monster Monday.
Inferna expected many things to happen- but sparks flying between her, the office rival, and his lover was not one of them.

Calen is a nerdy omega witch, one that Inferna wants to sink her teeth into. Art is a stuck-up boss but can be a little more charming outside the regular 9-5.

After an evil HR agent shows up with an agenda, everything starts to change. No one is safe, tensions are high, and the creatures of Warts & Claws Inc will have to fight spell and claw to make it to the weekend.

Can Inferna, Calen, and Art survive a work week from hell while discovering a love that’s off the charts?
