Volatile is the second studio album from The Lime Spiders, released in 1988 through Virgin Records on vinyl.
Carbonic acid is a chemical compound with the chemical formula H2CO3 (equivalently OC(OH)2). It is also a name sometimes given to solutions of carbon dioxide in water (carbonated water), because such solutions contain small amounts of H2CO3. In physiology, carbonic acid is described as volatile acid or respiratory acid, because it is the only acid excreted as a gas by the lungs.
Carbonic acid, which is a weak acid, forms two kinds of salts, the carbonates and the bicarbonates. In geology, carbonic acid causes limestone to dissolve producing calcium bicarbonate which leads to many limestone features such as stalactites and stalagmites.
The long-held belief that carbonic acid could not exist as a pure compound has reportedly been recently disproved by the preparation of the pure substance in both solid and gas form by University of Innsbruck researchers.
When carbon dioxide dissolves in water it exists in chemical equilibrium producing carbonic acid:
The hydration equilibrium constant at 25 °C is called Kh, which in the case of carbonic acid is [H2CO3]/[CO2] ≈ 1.7×10−3 in pure water and ≈ 1.2×10−3 in seawater. Hence, the majority of the carbon dioxide is not converted into carbonic acid, remaining as CO2 molecules. In the absence of a catalyst, the equilibrium is reached quite slowly. The rate constants are 0.039 s−1 for the forward reaction (CO2 + H2O → H2CO3) and 23 s−1 for the reverse reaction (H2CO3 → CO2 + H2O). Carbonic acid is used in the making of soft drinks, inexpensive and artificially carbonated sparkling wines, and other bubbly drinks. The addition of two molecules of water to CO2 would give orthocarbonic acid, C(OH)4, which exists only in minute amounts in aqueous solution.
In finance, volatility is the degree of variation of a trading price series over time as measured by the standard deviation of returns.
Historic volatility is derived from time series of past market prices. An implied volatility is derived from the market price of a market traded derivative (in particular an option). The symbol σ is used for volatility, and corresponds to standard deviation, which should not be confused with the similarly named variance, which is instead the square, σ2.
Volatility as described here refers to the actual current volatility of a financial instrument for a specified period (for example 30 days or 90 days). It is the volatility of a financial instrument based on historical prices over the specified period with the last observation the most recent price. This phrase is used particularly when it is wished to distinguish between the actual current volatility of an instrument.
A patent attorney is an attorney who has the specialized qualifications necessary for representing clients in obtaining patents and acting in all matters and procedures relating to patent law and practice, such as filing an opposition. The term is used differently in different countries, and thus may or may not require the same legal qualifications as a general legal practitioner.
The titles patent agent and patent lawyer are also used in some jurisdictions. In some jurisdictions the terms are interchangeable, while in others the latter is used only if the person qualified as a lawyer.
In Europe, requirements for practising as patent attorney before national patent offices should be distinguished from those needed for practising before the European Patent Office (EPO) or the Eurasian Patent Office (EAPO). On the national level, the requirements are not harmonized, although across the 28 Member States of the European Union respective professional qualifications are mutually recognised to some degree.
A sports agent procures and negotiates employment and endorsement contracts for an athlete. Agents are responsible for communications with team owners, managers, coaches, and other individuals. Primarily, agents are used to broker and negotiate contracts for their clients. Also, they are responsible for making recommendations in regard to the athlete's options. In addition to finding income sources, agents often handle public relations matters for their clients. In some large sports agencies, such as IMG, Creative Artists Agency, and Octagon, agents deal with all aspects of a client's finances, from investment to filing taxes.
Sports agents may be relied upon by their clients for guidance in all business aspects, and sometimes even more broadly. For example, hockey agents start recruiting clients as young as 15, allowing the agent to guide the athlete's career before the NHL draft, which happens usually at 18 years of age.
Due to the length and complexity of contracts, many sports agents are lawyers or have a background in contract law. Agents are expected to be knowledgeable about finance, business management, and financial and risk analysis, as well as sports. It is important for a sports agent to follow trends in sports. Other skills an agent must possess are excellent communication and negotiation skills. Agents must be highly motivated, willing to work long hours, and have the ability to multitask. It is very common for agents to be in negotiations on behalf of several clients at one time.
A shipping agency or shipping agent is the designated person or agency held responsible for handling shipments and cargo, and the general interests of its customers,at ports and harbours worldwide, on behalf of ship owners, managers, and charterers. In some parts of the world, these agents are referred to as port agents or cargo brokers. There are several categories of shipping agents such as: port agents, liner agents and own agencies, each rendering specific services depending on the shipping company they represent.
Shipping agents will usually take care of all the regular routine tasks of a shipping company quickly and efficiently. They ensure that essential supplies, crew transfers, customs documentation, and waste declarations are all arranged with the port authorities without delay. Quite often, they also provide the shipping company with updates and reports on activities at the destination port so that shipping companies have real-time information available to them while goods are in transit.
