A Place Between the Tides: A Naturalist's Reflections on the Salt Marsh
by Harry Thurston
from Greystone Books
This is the story of Thurston's return to the beloved environment of his boyhood. Elegantly moving back and forth in time, and deftly interweaving a naturalist's observations with a personal journey, he describes the seasons of the marsh over two decades. Altogether, Thurston documents more than 100 species of fish, birds, and mammals, a myriad of creatures hiding in tidal pools, and 70 species of plants.

Atlas and Data of Solid-Solution Equilibria of Marine Evaporites
by E. Usdowski
from Springer-Verlag Telos
The present volume provides an overview of the phase equilibria of marine evaporites and the solubilities of the alkaline and earth alkaline chlorides and sulfates which occur in salt deposits. The first part of the book explains how phase relations and their projections are derived from solubility data, how multicomponent systems are interrelated, and how numerical calculations with respect to precipitation and dissolution of solids are carried out. The second part describes the quinary seawater system and its pertinent 5 quaternary, 9 ternary, and 6 binary subsystems. The interrelation between the systems is illustrated by diagrams and tables. The attached computer program SALSYS allows easy and fast access to solubility data that are required by different fields.
The Salton Sea Centennial Symposium: Proceedings of a Symposium Celebrating a Century of Symbiosis Among Agriculture, Wildlife and People, 19052005, held ... March 2005 (Developments in Hydrobiology)
This volume deals with many aspects of the physical and chemical limnology of the Salton Sea, California’s largest lake and a lake that may soon to be the object of a multi-billion dollar restoration project. Formed in 1905 by an accidental breaching of outtake structures on the Colorado River, and maintained since then by large and steady inflows of agricultural wastewaters, it has long served as an important habitat for fish and waterbirds and as a major recreational area for people. Highlly eutrophic and with a salinity that is steadily rising and now nearly 50 g/L, it is a lake in great trouble. Most fish species have disappeared, and large fish and bird dieoffs have been common in recent decades. Many of the papers in this volume represent studies undertaken with the aim of informing the re-engineering of this ecosystem so that its value to wildlife and man can be restored or enhanced.

The 2007 Import and Export Market for Common Salt, Rock Salt, Sea Salt, Sea Water, and Pure Sodium Chloride in Sweden
by Philip M. Parker
from ICON Group International, Inc.
On the demand side, exporters and strategic planners focusing on common salt, rock salt, sea salt, sea water, and pure sodium chloride in Sweden face a number of questions. Which countries are supplying common salt, rock salt, sea salt, sea water, and pure sodium chloride to Sweden? How important is Sweden compared to others in terms of the entire global and regional market? How much do the imports of common salt, rock salt, sea salt, sea water, and pure sodium chloride vary from one country of origin to another in Sweden? On the supply side, Sweden also exports common salt, rock salt, sea salt, sea water, and pure sodium chloride. Which countries receive the most exports from Sweden? How are these exports concentrated across buyers? What is the value of these exports and which countries are the largest buyers? This report was created for strategic planners, international marketing executives and import/export managers who are concerned with the market for common salt, rock salt, sea salt, sea water, and pure sodium chloride in Sweden. With the globalization of this market, managers can no longer be contented with a local view. Nor can managers be contented with out-of-date statistics which appear several years after the fact. I have developed a methodology, based on macroeconomic and trade models, to estimate the market for common salt, rock salt, sea salt, sea water, and pure sodium chloride for those countries serving Sweden via exports, or supplying from Sweden via imports. It does so for the current year based on a variety of key historical indicators and econometric models. In what follows, Chapter 2 begins by summarizing where Sweden fits into the world market for imported and exported common salt, rock salt, sea salt, sea water, and pure sodium chloride. The total level of imports and exports on a worldwide basis, and those for Sweden in particular, is estimated using a model which aggregates across over 150 key country markets and projects these to the current year. From there, each country represents a percent of the world market. This market is served from a number of competitive countries of origin. Based on both demand- and supply-side dynamics, market shares by country of origin are then calculated across each country market destination. These shares lead to a volume of import and export values for each country and are aggregated to regional and world totals. In doing so, we are able to obtain maximum likelihood estimates of both the value of each market and the share that Sweden is likely to receive this year. From these figures, rankings are calculated to allow managers to prioritize Sweden compared to other major country markets. In this way, all the figures provided in this report are forecasts that can be combined with internal information sources for strategic planning purposes.

Adaptive Polarization of Antennas
from Storming Media
This is a AIR FORCE INST OF TECH WRIGHT-PATTERSONAFB OH report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A261693. The abstract provided by the Pentagon follows: Antennas whose polarizations are not aligned for optimal power transfer create a polarization mismatch and a loss in transferred power. A compensation for polarization mismatch is considered using a pair of crossed dipoles. One of the dipoles amplitude and phase is adjusted by a MATLAB optimization, and the Numerical Electromagnetic Code generates the electromagnetic response. Optimizing only for circular polarization produces losses in radiated power that offset the polarization correction. With minimum dipole separation, minor improvements are possible for 0 < 15 deg F, but at larger angles the optimizer decreases the power transferred. The polarization optimization improves power transferred when the dipole spacing is increased. At 0.5 wavelength spacing, the increase in total gain is up to 17 dB. The optimization was modified to consider power transferred, and the power always increased up to a maximum of 2.0 dE at 0 = 800. Crossed dipoles as the transmitter and receiver were also considered and they improved the power transferred.
