Groundwater is an increasingly important resource to human populations around the world, and the study and protection of groundwater is an essential part of hydrogeology - the subset of hydrology that concentrates on the subsurface. Environmental isotopes, naturally occurring nuclides in water and solutes, have become fundamental tools for tracing the recharge, history, and contamination of groundwater.

Propositional quantifiers are quantifiers binding proposition letters, understood as variables. This Element introduces propositional quantifiers and explains why they are especially interesting in the context of propositional modal logics. It surveys the main results on propositionally quantified modal logics which have been obtained in the literature, presents a number of open questions, and provides examples of applications of such logics to philosophical problems.

The notions of necessity and possibility, as well as the notion of a possible world, are ubiquitous in philosophy. Nevertheless, these notions remain controversial. It also remains controversial whether metaphysics requires notions drawing distinctions which are finer than those which can be drawn in terms of necessity and possibility, such as the recently much-discussed notion of grounding. In order to make progress on these debates, this book develops a general framework for theorizing about such intensional notions using the tools of higher-order logic. The Foundations of Modality begins by motivating the use of higher-order logic, and introduces a particularly simple form of higher-order logic. Progress is made on well-trodden territory concerning modality and possible worlds by considering first the question how fine propositions are individuated. Peter Fritz uses both logical results and philosophical arguments to motivate a relatively coarse-grained individuation of propositions. Fritz shows that a number of putative metaphysical notions are ruled out by this theory of individuation. Furthermore, the theory allows the controversial notion of (metaphysical) necessity to be delineated as the broadest necessity, which applies just to the single tautologous proposition. This book also vindicates appeals to possible worlds: First, it shows that if anything plays the theoretical role of possible worlds, then certain propositions do so. Second, it argues that there are in fact the required propositions playing the role of possible worlds; this is shown using the notion of plural quantification over propositions in higher-order logic.

After the GFC and then a divorce destroyed everything I'd built, all that remained was a $140,000 debt and a textbook midlife crisis. 'Debt-free' explains in simple actionable terms, how I killed my debts, broke old habits and started living again. In just one hour, I show you: - Why your lifestyle keeps you broke- The debts to avoid and the ones that make you wealthy- How to deal with a scary tax debt- What to do if you can't repay your debt- How to generate free money with your credit card- How to pay off your consumer debt without a budget My book's 3-step process provides a clear path to eliminating your consumer debts and ensuring you never suffer from them again. If you've ever felt the pressure of mounting debt and that choking sense of overwhelm, you know exactly how stressful it can be. This one-hour read gives you a roadmap up the mountain and out of the mess so you can start living again. Mainstream marketing would have us believe otherwise, but life isn't meant to be a continuous struggle of debt and struggle. This little book reverses the damage and gets you back on the right path. A gentle warning, though - it isn't for wishful thinkers, excuse makers or status-seeking Jones-pleasers. It's more like a killing spree, where all the habits that led to your debts are knocked off one by one, and with them, the debts that are holding you back from a stress-free life. Follow the steps in this book, and soon you'll be on your way to a debt-free, stress-free life.

The profit principle is the only secret to good business you'll ever need to know. Success in business has little to do with investment capital, a business plan or office space. Success comes from applying the four-part profit principle. Discover how you can turn what you know into what you do, and launch a successful, sustainable venture without spending (or borrowing) a cent. It’s a process that's simpler than you think and already within reach. Most books on starting a business don't extend further than the practicalities: plans, finance, accounting, equipment and so on. There are so many books on this topic, and their advice is often similar and predictable; rarely do they offer a new perspective or directions for a smarter approach. The motivational books that also serve this market may read well, but they often lack the substance on which to base sound business decisions and actions. If you want to run your own business and don't already, stop and ask yourself why not? The Profit Principle is a modern classic that will revolutionise your thinking on what it takes to succeed and inspire you to get started.

Grundstucke, die nicht unmittelbar an eine Verkehrsanlage grenzen, werfen in besonderer Weise die Frage nach der fur eine Abgabepflicht massgeblichen Vorteilssituation auf. Die Untersuchung gelangt zu dem Ergebnis, dass der Eigentumer einer solchen Hinterliegerparzelle grundsatzlich wie jeder andere Anlieger beitragspflichtig ist. Dieser Grundsatz erfahrt eine verfassungsrechtlich gebotene Ausnahme in besonders qualifizierten Fallen nur eingeschrankter Ausnutzbarkeit des Grundstucks."
