"Simple text and full-color photography introduce beginning readers to adders. Developed by literacy experts for students in kindergarten through third grade"--

In 2019 the most comprehensive survey ever of adders was published. According to ‘Make the Adder Count’ the species will disappear from most of Britain in the next 15-20 years unless we take action now to save it. But despite being a priority conservation species under the Biodiversity Action Plan, not a single nature reserve in Britain has been specifically designated to protect it. Throughout our history we have systematically persecuted the adder over generations because it is Britain’s only venomous snake. Now the adder population is in dire straits, its rapidly declining numbers occurring on increasingly small, isolated and fragmented sites. According to Make the Adder Count 90% of the sites where it still occurs have 10 or less adult snakes and are now considered to be very vulnerable to local extinction. Despite the adder population being in dire straits, it is still not too late to save it if we act now. This book contains a 10 point adder action plan which if implemented could help to restore the adder to its former range across Britain. Using many unique photographs of the species published for the first time, it also contains a history of the adder and reveals its secret life which has made it the most successful snake in the world. With a foreword by Iolo Williams, the BBC Springwatch presenter, this book is a story of our times, one which typifies the age of extinction through which we are all living and are all responsible.

Introduces characteristics, habitat, and behaviors of the Common adder snake.

"The common European adder (Vipera berus) is found throughout Europe and northern Asia. Despite its widespread distribution, and its notoriety as one of Europe's few truly venomous snakes, very little is known about its private life. Rodger McPhail, the celebrated wildlife artist, has had a life-long fascination with adders. He has been observing and photographing them on his local moor in Lancashire for many years. His unique collection of photographs reveals adders as never before seen and his succinct text offers an insight into this fascinating reptile. "

Even though it’s smaller than many killer snakes, the death adder is still very dangerous. Readers will soon discover exactly why this snake is so aptly named. Colorful photographs show this venomous snake in action as readers learn exciting facts about how death adders hunt, eat, and survive. Excellent Spanish translations provide engaging support for bilingual learners.

Adders are the basic building blocks of any processor or data path application. In adder design, carry generation is the critical path. To reduce the power consumption of the data path, we need to reduce the area of the adder. Carry Select Adder is one of the fast adders used in may data path applications. The proposed design is implemented without using multiplexer and RCA structure with Cin=1. Instead of using multiplexer and RCA Cin=1 structure, we use simple combinational circuit. After speed, power dissipation is one of the most important design objectives in integrated circuits. As adders are the most widely used components in such circuits, the design of efficient adder is of much concern for researchers. This study presents a performance analysis of different Fast Adders. The comparison is done on the basis of three performance parameters, i.e. Area, Speed and Power consumption. We also show a modified carry select adder designed at different stages.
