Product Description: Kids use simple machines every day without realizing it. Teeth are wedges and so are knives, forks, and thumb tacks. Many toys such as slides, which are inclined planes, and seesaws, which are levers, are also simple machines. Two appealing kids and their comical cat introduce levers, wheels, pulleys, inclined planes, and more, amd explain how they work...read more

Product Description: In Bicycles, early fluent readers explore the physics behind this popular child's vehicle. Vibrant, full-color photos and carefully leveled text engage young readers as they explore how a bicycle works.

Product Description: FOR USE IN SCHOOLS AND LIBRARIES ONLY. This illustrated introduction of the six simple machines includes coverage of the lever, wheel and axle, pulley, ramp, wedge, and screw.

Product Description: Is it easier to move heavy box with an inclined plane or wheels and axles?

This reference text covers many topics concerning renal disease, such as the ways antibodies induce glomerular injury and the controls governing immune responses, giving insights into avenues for modulating and manipulating these responses for therapeutic benefit. Other subjects covered include the membrane attack complex of complements and oxidants released by inflammatory cells, the cellular immune mechanisms in glomerular and tubulointerstitial renal injury, the roles of glomerular cells as both responders and potential instigators of change, the utilization of sophisticated physiologic measurements of glomerular haemodynamics and function and the evidence for and against an immune complex aetiology for IgA nephropathy. Therapeutic techniques for the more common forms of immunologic renal injury are also examined.
