Описание:
Marvel at more than 600 beautiful, bold, and bizarre plants and flowers in this follow-up to the best-selling Creaturepedia--featuring the fun, colorful illustrations of Adrienne Barman and finished with an embossed cover and a grosgrain ribbon marker.
Filled with fascinating flowers, curious crops, and wonderful weeds, this book will keep young explorers busy for hours. Alphabetically ordered by their special traits and characteristics, including:
The big eaters - meet the insect-digesting plants, such as the Venus flytrap
The confused fruits - avocado, tomato, eggplant, and more you thought were veggies
The giants - admire among them the elephant cactus, which grows up to 50 feet tall
The guests - with parasites such as mistletoe, which sucks nutrients from trees
The healers - a collection of medicinal plants, such as echinacea, tea tree, and chamomile
The old-timers - featuring the giant sequoia, which can live for over 3,000 years
Irene Kelleher lived all her life in the shadow of her inheritance. Her local community in British Columbia's Fraser Valley all too often treated her as if she was invisible. The combination of white and Indigenous descent that Irene embodied was beyond the bounds of acceptability by a dominant white society. To be mixed was to not belong.
Attracted to the future British Columbia by a gold rush beginning in 1858, Irene's white grandfathers had families with Indigenous women. Theirs was not an uncommon story. Some of the earliest newcomers to do so were in the employ of the fur trading Hudson's Bay Company at Fort Langley. And yet, more than one hundred and fifty years later, the descendants of these early pioneers are still waiting for their stories to be heard.
Through meticulous research, family records and a personal connection to Irene, Governor General award-winning historian Jean Barman explores this aspect of British Columbia's history and the deeply rooted prejudice faced by families who helped to build Canada. Invisible Generations evokes the Catholic residential school that Irene's parents and so many other "mixed blood" children attended. Among Irene's family and friends we meet Josephine, who was separated as a child from her beloved upwardly mobile politician father. When her presence in his socially charged household became untenable, Josephine was dispatched to the same Fraser Valley boarding school. "The transition from genteel Victoria to St. Mary's Mission was horrendous," she wrote. Yet individuals and families survived as best they could, building good lives for themselves and those around them. Irene was determined to be a schoolteacher and taught across the farthest reaches of the province, including Doukhobor children at a time when the community was vehemently opposed to their offspring attending school.
Stories like that of Irene and of her family and friends have been largely forgotten, but in Invisible Generations Barman brings this important conversation into focus, shedding light on a common history across British Columbia and Canada. It is, in Irene's words, "time to tell the story."

Описание: This book presents comprehensive accounts of the chemistry revolving around the sulphonamides. Sulfonamides are widely present in various drugs as a functional group and are a manmade synthetic drug. Hence, their extended research is a prerequisite for every practitioner of organic chemistry. Chapter 1 introduces the synthesis, reactivity, acidity, and pharmaceutical properties of the sulphonamides. It highlights the synthesis of biologically active sulphonamides, the study of their biological activity by QSAR method, and their medical applications. Chapter 2 deals with the classification of sulphonamides (i.e. acyclic and cyclic) and their structural activity relationship. It also describes the application of sulphonamides in pharmaceuticals as antimicrobial, anti-diabetic, anti-viral, anti-cancer, anti-inflammatory and anti-malarial agents. Chapter 3 reviews the synthetic attempts towards sulphonamide synthesis by employing the fixation of sulphur-dioxides. These approaches have been categorized into three parts: a) transition metal-catalyzed, b) employing Lewis acid, c) photocatalytic. Chapter 4 discusses the use of sulphonamides as potent organocatalysts, briefly describing how the mono- and C2-symmetric bis-sulfonamides act as efficient bifunctional and multifunctional organocatalysts in the enantioselective Michael addition of carbonyl compounds to I±,I?-unsaturated compounds. Chapter 5 details the oxidative sulphonamidation of alkenes and dienes, which also direct the routes to the synthesis of numerous heterocycles and linear compounds. Special emphasis is given to the comparison of reactivity of triflamides, arenesulfonamides, and the deprotection of sulfonamides. Chapter 6 describes the therapeutic properties of sulphonamides, which are significantly increased by the presence of the metal ions and ligands. This complex generation provides the opportunity to exploit the unique properties of metal centers, such as multiple oxidation states, redox properties, a wide variety of coordination numbers, symmetries and structural patterns, which offer highly adaptable platforms for drug design. Chapter 7 provides an overview of the clinical applications of sulphonamides on the toxicity and pharmacokinetic aspects of various sulpha-drugs. The mechanism involved in the development of sulfonamide resistance is briefly discussed. Thus, this book summarizes important attempts undertaken by chemists and biologists worldwide in the area of sulphonamides. Most importantly, the book also correlates the structural activity relationship and the related biological activity of the sulphonamides, attracting both novice and experienced chemists across the globe.
