It can be lonely sometimes on a rainy day in a big house with no one else around and there’s only the quiet to keep you company. But if you find a key, a mysterious key, that leads you to an unexpected place . . . chances are your afternoon is about to get a lot more interesting.
One major threat to cities at present is the increasing rainstorm waterlogging hazards due to climate change and accelerated urbanization. This paper explores the mechanism of rainstorm waterlogging and enables the fine simulation of surface water propagation over complex urban terrain. A novel community-scale waterlogging modeling scheme is presented by loosely coupling a one-dimensional sewer model with a two-dimensional overland model under an open-source framework. The coupled model was applied to Waigaoqiao Free Trade Zone located in Pudong New Area of Shanghai. To quantify the influence of rainfall intensity and drainage conditions on the waterlogging, 12 scenarios were constructed by combining four rainfall return periods (3, 5, 10, and 20 a) and three startup water depths (1.5, 2.0, and 2.5 m) of pump stations. The multi-scenario simulation results show that the waterlogging risk increases from north to south in the study area, and that risk zones with water depth above 0.3 m are mostly concentrated in the southwest and southeast corners of the site. The longer the rainfall return period, the larger the submerged area, and the spatial distribution of surface water accumulation is affected by local topography and drainage system. In addition, reducing the startup water depth of pump stations has an obvious effect on inhibiting the severity of water accumulation. The results provide insights into overland flow across an urban area with densely populated buildings and help to reduce the risk of rainstorm-induced waterlogging disasters.
A Collection of Thoughts, Sayings and Meditations on the Way of the Samurai "It is said that what is called "the spirit of an age" is something to which one cannot return. That this spirit gradually dissipates is due to the world's coming to an end. For this reason, although one would like to change today's world back to the spirit of one hundred years or more ago, it cannot be done. Thus it is important to make the best out of every generation." — Tsunetomo Yamamoto, Hagakure: The Book of the Samurai A formerly secret text known only to the Samurai, Hagakure is a classic text on Bushido--the Way of the Warrior. More than just a handbook for battle, Hagakure is a text that filled with teachings that still apply in business, political and social situations today.

This book dexterously weaves the storied philosophical themes of truth, ethics, and aesthetics together with the theories of relativity, quantum mechanics, neuroscience, epigenetics, social Darwinism, utilitarianism, evolutionary psychology, and modern art-from the soberest rationality to the wildest conjecture.
Newbery Medalist Karen Hesse recreates the body and soul-renewing experience of a summer downpour after a sweltering city heat wave. "Come on, rain!" Tess pleads to the sky as listless vines and parched plants droop in the endless heat. Up and down the block, cats pant while heat wavers off tar patches in the broiling alleyway. More than anything, Tess hopes for rain. And when it comes, she and her friends are ready for a surprising and joyous celebration....Through exquisite language and acute observation, Newberry medalist Karen Hesse recreates the glorious experience of a quenching rainstorm on a sweltering summer day. Jon J Muth's masterful and lyrical watercolors perfectly reflect the spirit of the text.
Over the last 20 years, writer and filmmaker Jon Bowermaster has profiled, traveled with, written with and about a wide cross-section of the world's most interesting environmentalists, explorers and professional wanderers. Whether roaming the plains of Kenya with Peter Beard or dog sledding in the high Arctic with Sir Richard Branson, from fishing and rafting with Bobby Kennedy Jr. to a bedside interview with Nobel Peace Prize winner Wangari Maathai, from sailing across the Atlantic Ocean with Frenchman Titouan Lamazou to traversing the Bronx Zoo with George Schaller, Bowermaster gives us a one-of-a-kind look at environmental policy and global exploration around the world today. Bowermaster has explored the remote corners of the world and the state of the globe's environment for a variety of national and international publications. A six-time grantee of the National Geographic Expeditions Council, he is the author of nine books and has made a dozen documentary films about his own expeditions. Begun in 1998, his ten-year-long OCEANS 8 project, which took him and his teams around the world by sea kayak one continent at a time, provided a unique, sea-level look at both the health of the world's oceans and the lives of people who depend on them.
