nofootnotes date March 2011 In finance, an asset liability mismatch occurs when the financial terms of an institution s assets and liabilities do not correspond. Several types of mismatches are possible. For example, a bank that chose to borrow entirely in US dollars and lend in Russian ruble s would have a significant currency mismatch if the value of the ruble were to fall dramatically, the bank would lose money. In extreme cases, such movements in the value of the assets and liabilities could lead to bankruptcy , liquidity problems and wealth transfer . As another example, a bank could have substantial long term assets such as fixed rate mortgage s but short term liabilities, such as deposits . This is sometimes called a maturity mismatch , which can be measured by the duration gap . Alternatively, a bank could have all of its liabilities as floating interest rate bonds, but assets in fixed rate instruments. Mismatches are handled by asset liability management . Asset liability mismatches are important to insurance companies and various pension plans, which may have long term liabilities promises to pay the insured or pension plan participants that must be backed by assets. Choosing assets that are appropriately matched to their financial obligations is therefore an important part of their long term strategy. Few companies or financial institutions have perfect matches between their assets and liabilities. In particular, the mismatch between the maturities of banks deposits and loans makes banks susceptible to Bank run Theory bank runs . On the other hand, controlled mismatch, such as between short term deposits and somewhat longer term, higher interest loans to customers is central to many financial institutions business model. Asset liability mismatches can be controlled ...

Hernias can occur in many places, including the Umbilical hernia abdomen , Inguinal hernia groin , Diaphragmatic hernia diaphragm , Brain herniation brain , and at Incisional hernia the site of a previous operation . There are many different approaches to the surgical repair of hernias, including herniorrhaphy , hernioplasty , and herniotomy . Hernia repair is often performed as an Ambulatory care ambulatory procedure . Repair may correct inguinal hernia , femoral hernia , umbilical hernia , or other hernias. Techniques main Inguinal hernia repair An operation in which the hernia sac is removed without any repair of the inguinal canal is described as a herniotomy. When herniotomy is combined with a reinforced repair of the posterior inguinal canal wall with autotransplantation autogenous patient s own tissue or Homogeneity and heterogeneity heterogeneous material such as prolene mesh, it is termed hernioplasty as opposed to herniorrhaphy, in which no autogenous or heterogeneous material is used for reinforcement.

Refimprove date May 2007 Home repair involves the diagnosis and resolution of problems in a home, and is related to home maintenance to avoid such problems. Many types of repairs are do it yourself DIY projects, while others may be so complicated, time consuming or risky as to suggest the assistance of a qualified handyman , property manager , independent contractor contractor builder, or other professional s. Repair is not necessarily the same as home improvement , although many improvements can result from repairs or maintenance. Often the costs of larger repairs will justify the alternative of investment in full scale improvements. It may make just as much sense to upgrade a home system with an improved one as to repair it or incur ever more frequent and expensive maintenance for an inefficient, obsolete or dying system. For a DIY project, it is also useful to establish limits on how much time and money you re willing to invest before deciding a repair or list of repairs is overwhelming and discouraging, and less likely to ever be completed.

The repair and mending of parchment has taken place for thousands of years. Methods from the earliest hand stitching of tears to today s use of modern equipment to mend and fill parchment show the importance that has been placed on its Preservation library and archival science preservation and Art conservation conservation . Flattening and crease removal Repairing curling and crease lines in parchment is generally achieved by raising its moisture content, though some modern techniques use little or no water. Wetting parchment can cause damage, though it is sometimes unavoidable. If the entire piece of parchment needs to be flattened, one technique is to place the parchment into a controlled humidity chamber with a relative humidity of 95 or more. According to Bety Haines , one important factor to monitor is to make sure the vapor has penetrated to the core uniformly, and at its own rate, and not just the surface of the parchment. Once this has happened, the use of tensioning with clips will allow creases to be eased. If just a few creases need to be eased, 80 to 90 isopropyl alcohol may be applied to the creases directly.

Not to be confused with the book The Selfish Gene . Selfish DNA refers to those sequences of DNA which, in their purest form, have two distinct properties 1 the DNA sequence spreads by forming additional copies of itself within the genome and 2 it makes no specific contribution to the reproductive success of its host organism . This idea was sketched briefly by Richard Dawkins in his 1976 book The Selfish Gene and was explicitly exposed in two 1980 articles in Nature magazine. According to one of these articles quotation The theory of natural selection, in its more general formulation, deals with the competition between replicating entities. It shows that, in such a competition, the more efficient replicators increase in number at the expense of their less efficient competitors. After a sufficient time, only the most efficient replicators survive. L.E. Orgel & F.H.C. Crick Selfish DNA the ultimate parasite The selfish DNA can be considered an efficient replicator that follows another way of increasing in number.

It binds to UV damaged DNA containing pyrimidine dimers and, upon absorbing a near UV photon 300 to 500 nm , breaks the cyclobutane ring joining the two pyrimidine s of the dimer. DNA photolyase is an enzyme that requires two chromophore cofactors for its activity a reduced FAD FADH2 and either 5,10 methenyltetrahydrofolate 5,10 Methenyltetrahydrofolate 5,10 MTFH or an oxidized 8 hydroxy 5 deazaflavin 8 HDF derivative Coenzyme F420 F420 . The folate or deazaflavin chromophore appears to function as an antenna, while the FADH2 chromophore is thought to be responsible for electron transfer. On the basis of sequence similarities DNA photolyases can be grouped into two classes. The first class contains enzymes from Gram negative and Gram positive bacteria, the halophilic archaebacteria Halobacterium halobium, fungi and plants. Class 1 enzymes bind either 5,10 MTHF Escherichia coli E. coli , fungi, etc. or 8 HDF Streptomyces griseus S. griseus , Halobacterium H. halobium . Proteins containing this domain also include Arabidopsis thaliana cryptochromes 1 CRY1 and 2 CRY2 , which are blue light photoreceptors that mediate blue light induced gene expression. Examples Human proteins containing this domain include CRY1 CRY2 References Reflist InterPro content IPR005101 protein stub Category Protein domains ... more details
