Halite karst geohazards (natural and man-made) in the United Kingdom. Environmental Geology, Vol. 42, 505-512. This work is based on a paper presented to the 8th Multidisciplinary Conference on Sinkholes and the Engineering and Environmental impact of karst, Louisville, Kentucky, April 2001. In the United Kingdom Permian and Triassic halite (rock salt) deposits have been affected by natural and artificial dissolution producing karstic landforms and subsidence. Brine springs from the Triassic salt have been exploited since Roman times, or possibly earlier, indicating prolonged natural dissolution. Medieval salt extraction in England is indicated by the of place names ending in “wich” indicating brine spring exploitation at Northwich, Middlewich, Nantwich and Droitwich. Later, Victorian brine extraction in these areas accentuated salt karst development causing severe subsidence problems that remain a legacy. The salt was also mined, but the mines flooded and consequent brine extraction caused the workings to collapse, resulting in catastrophic surface subsidence. Legislation was enacted to pay for the damage and a levy is still charged for salt extraction. Some salt mines are still collapsing and the re-establishment of the post-brine extraction hydrogeological regimes means that salt springs may again flow causing further dissolution and potential collapse. -

Life at Low Water Activity
Published online 12 July 2004 Life at low water activity W. D. Grant Department of Infection, Immunity and Inflammation, University of Leicester, Maurice Shock Building, University Road, Leicester LE1 9HN, UK ([email protected]) Two major types of environment provide habitats for the most xerophilic organisms known: foods pre- served by some form of dehydration or enhanced sugar levels, and hypersaline sites where water availability is limited by a high concentration of salts (usually NaCl). These environments are essentially microbial habitats, with high-sugar foods being dominated by xerophilic (sometimes called osmophilic) filamentous fungi and yeasts, some of which are capable of growth at a water activity (aw) of 0.61, the lowest aw value for growth recorded to date. By contrast, high-salt environments are almost exclusively populated by prokaryotes, notably the haloarchaea, capable of growing in saturated NaCl (aw 0.75). Different strategies are employed for combating the osmotic stress imposed by high levels of solutes in the environment. Eukaryotes and most prokaryotes synthesize or accumulate organic so-called ‘compatible solutes’ (osmolytes) that have counterbalancing osmotic potential. A restricted range of bacteria and the haloar- chaea counterbalance osmotic stress imposed by NaCl by accumulating equivalent amounts of KCl. Haloarchaea become entrapped and survive for long periods inside halite (NaCl) crystals. They are also found in ancient subterranean halite (NaCl) deposits, leading to speculation about survival over geological time periods. Keywords: xerophiles; halophiles; haloarchaea; hypersaline lakes; osmoadaptation; microbial longevity 1. INTRODUCTION aw = P/P0 = n1/n1 ϩ n2, There are two major types of environment in which water where n is moles of solvent (water); n is moles of solute; availability can become limiting for an organism. -
Salt (Chemistry) - Wikipedia
Salt (chemistry) - Wikipedia https://en.wikipedia.org/wiki/Salt_(chemistry) Salt (chemistry) In chemistry, a salt is a chemical compound consisting of an ionic assembly of cations and anions.[1] Salts are composed of related numbers of cations (positively charged ions) and anions (negatively charged ions) so that the product is electrically neutral (without a net charge). ese component ions can be inorganic, − − − such as chloride (Cl ), or organic, such as acetate (CH3CO2); and can be monatomic, such as fluoride (F ) 2− or polyatomic, such as sulfate (SO4 ). Contents Types of salt Properties Color Taste Odor Solubility Conductivity Melting point Nomenclature Formation Strong salt Weak salt See also References Types of salt Salts can be classified in a variety of ways. Salts that produce hydroxide ions when dissolved in water are called alkali salts. Salts that produce acidic solutions are acid salts. Neutral salts are those salts that are neither acidic nor basic. Zwierions contain an anionic and a cationic centre in the same molecule, but are not considered to be salts. Examples of zwierions include amino acids, many metabolites, peptides, and proteins.[2] Properties Color Solid salts tend to be transparent as illustrated by sodium chloride. + − In many cases, the apparent opacity or transparency are only BMIM PF6 , an ionic liquid related to the difference in size of the individual monocrystals. Since light reflects from the grain boundaries (boundaries between 1 von 6 29.03.21, 15:43 Salt (chemistry) - Wikipedia https://en.wikipedia.org/wiki/Salt_(chemistry) crystallites), larger crystals tend to be transparent, while the polycrystalline aggregates look like white powders. -

The saline pan lies within the Dorob National Park along the central coastline north of the town of Henties Bay. Gecko was granted an exploration licence (EPL4426) over this pan and its surrounding in 2015. The company intends to apply for a mining licence over the area for producing salt on the saline pan. The envisaged development includes a 13-kilometre-long brine pipeline from Gecko’s Mining Licence at Cape Cross (ML210) to the future solar salt production facility at Mile 68. -
Soviet Political Parties and Leadership
ABSTRACT Title of Dissertation: EMANCIPATION FROM DOUBLETHINK? POST- SOVIET POLITICAL PARTIES AND LEADERSHIP Peter Voitsekhovsky, Doctor of Philosophy, 2013 Dissertation directed by: Professor Vladimir Tismaneanu Department of Government and Politics This study examines the phenomenon of doublethink as a core feature of the “mental software” that continues to define the character of post-Soviet societies. It is revealed in patterns of prevarication and equivocation that characterize the thinking and behavior of both the elites and the masses. Doublethink is also manifested in incongruous values and duplicitous rules that prevail in society. It accounts for the perpetuation of simulative and fake institutions of “façade democracy.” Political parties in post-Soviet Ukraine are analyzed as a major example of simulative and imitative institutions. Here, traditional ideology-based party taxonomies prove misleading. Political parties are quasi-virtual entities with the character of “post- Orwellian political machines”: they operate in a topsy-turvy world of imitated supply and deluded demand. The study employs three levels of analysis: macro (surveys data and “Tocquevillean” observations); meso (biographical data and political discourse analysis); and micro (in-depth interviews).

Road Salt and Water Quality Fact Sheet WMB-4
WMB-4 2021 Road Salt and Water Quality Snowfall in New Hampshire and the necessity to travel on roads require winter snow and ice management by the state, municipalities and the private sector. Deicing materials are often used in order to keep the public safe during these winter weather events. The most commonly used de-icing chemical is sodium chloride (NaCl), commonly known as road salt. Road salt is readily available, and it is easy to handle, store and spread. Its purpose is to reduce the adherence of snow and ice to the pavement, preventing the formation of hard pack. Once hard pack forms, it is difficult to remove by plowing alone. In the United States from 2005-2009 an average of 23 million tons of salt were applied to our roads, parking lots, sidewalks and driveways each year.1 Studies have shown that, in urbanized areas, about 95% of the chloride inputs to a watershed are from road and parking lot deicing. In four chloride impaired watersheds in the southern I-93 corridor of New Hampshire, road salt sources were 10% to 15% from state roads, 30% to 35% from municipal roads, and 45% to 50% from private roads and parking lots. How Salt Works Pounds of Ice Melted per Pound of Salt The first step in melting ice is to lower its freezing point. This is done through the formation of brine where salt 50 crystals pull water molecules out of ice formation. Once 40 the brine is formed, melting is greatly accelerated. The rate 30 at which melting occurs is dependent on the temperature.
