In this edited volume, global experts in ecology and evolutionary biology explore how theories in ecology elucidate the processes of invasion, while also examining how specific invasions inform ecological theory. This reciprocal benefit is highlighted in a number of scales of organization: population, community and biogeographic. The text describes example invaders in all major groups of organisms and from a number of regions around the globe.
Chapter 4 - Energy analysis of closed systems. The objectives of Chapter 4 are to: Examine the moving boundary work or P dV work commonly encountered in reciprocating devices such as automotive engines and compressors, identify the first law of thermodynamics as simply a statement of the conservation of energy principle for closed (fixed mass) systems, develop the general energy balance applied to closed systems,...
Chapter 9 - Gas power cycles. The objectives of Chapter 9 are to: Evaluate the performance of gas power cycles for which the working fluid remains a gas throughout the entire cycle; develop simplifying assumptions applicable to gas power cycles, review the operation of reciprocating engines, analyze both closed and open gas power cycles,...

A centrifugal pump is a rotating machine in which flow and pressure are generated
dynamically. The inlet is not walled off from the outlet as is the case with positive dis-
placement pumps,whether they are reciprocating or rotary in configuration. Rather, a cen-
trifugal pump delivers useful energy to the fluid or “pumpage” largely through velocity
changes that occur as this fluid flows through the impeller and the associated fixed pas-
sageways of the pump; that is, it is a “rotodynamic” pump.
Microbes produce an extraordinary array of microbial defense systems. These
include broad-spectrum classical antibiotics, metabolic byproducts, such as
the lactic acids produced by lactobacilli, lytic agents such as lysozymes,
numerous types of protein exotoxins, and bacteriocins, which are loosely
defined as biologically active protein moieties with a bacteriocidal mode of
The natural world is a place I escape to: a place that goes about its business
regardless of everyday individual human concerns. It is a place of beauty,
change, diversity, and endless fa scination. Like many who share these sentiments,
I was never content to just be in nature: I had to watch, name, learn,
and understand. This book is about understanding how and why the natural
world works, thereby to appreciate it more for what it really is. For me, that is
one of the things that make life ‘more than just living’....
