With the Persona® knee system a new polyethylene formulation incorporating vitamin-E which aims to reduce oxidation and maintain wear resistance was introduced. Although in-vitro studies have demonstrated positive efects of the vitamin-E antioxidants on UHMWPE, no retrieval study has looked at polyethylene damage of this system yet.

Titanium instrumentations are widely used in orthopedics; the metal bonds with bone in a process called osseointegration. Over time, hydrocarbons adhere to the instrumentation, which weakens the bone-binding ability. Ultraviolet photofunctionalization enhances the bone-binding ability of instrumentation by reducing hydrocarbons.

Polyether-ether-ketone (PEEK) is increasingly being used for spinal applications. However, because of its biologically inactive nature, there are risks of false joint loosening and sinking. PEEK materials are coated with apatite to enhance the osteoconductive properties.

Protein structure can be described by backbone torsion angles: rotational angles about the N-Cα bond (φ) and the Cα-C bond (ψ) or the angle between Cαi-1-Cαi -Cαi+1 (θ) and the rotational angle about the Cαi -Cαi+1 bond (τ). Thus, their accurate prediction is useful for structure prediction and model refinement.

Marfan syndrome (MFS) is a heritable disorder of connective tissue resulting from pathogenic variants of the fibrillin-1 gene (FBN1). Neonatal Marfan syndrome (nMFS) is rare and the most severe form of MFS, involving rapidly progressive cardiovascular dysfunction leading to death during early childhood.

Human acid sphingomyelinase (haSMase, EC 3.1.4.12) catalyzes the lysosomal degradation ofsphingomyelin to ceramide and phosphorylcholine. An inherited haSMase deficiency leads toNiemann–Pick disease, a severe sphingo-lipid storage disorder. The enzyme was purified and cloned over 10 years ago. Since then, only a fewstructural properties of haSMase have been elucidated.

In the United States, insurance regulators require bonds and preferred stocks to be reported in statutory financial statements in one of six National Association of Insurance Commissioners (NAIC) designations categories that denote credit quality. If an accepted rating organisation (ARO) has rated the security, the security is not required to be filed with the NAIC’s Securities Valuation Office (SVO). Rather, the ARO rating is used to map the security to one of the six NAIC designation categories.

Operators that have obtained a lease must submit an application for a permit to drill to BLM before beginning to prepare land or drilling any new oil or gas wells. The complete permit application package is a lengthy and detailed set of forms and documents, which, among other things, must include proof of bond coverage and a surface use plan of operations; this surface use plan must include a reclamation plan that details the steps operators propose to take to reclaim the site. However, operators generally do not have to submit cost estimates for completing the reclamation.

The informational efficiency of the bond market relative to the stock market has received increasing attention in recent years. For example, Kwan (1996) finds, using daily data, that stock returns lead bond returns, suggesting that stocks may be informationally more efficient than bonds, while Hotchkiss and Ronen (2002) find, using higher-frequency (intra- day) data, that the informational efficiency of corporate bonds is similar to that of the underlying stocks.

There has been increasing interest in exploring fi nancial instruments that could limit the cyclical vulnerabilities of developing countries and reduce the likelihood of defaults and debt crises. GDPindexed bonds fall into this category and may also generate a wider range of benefi ts for issuer countries, investors and the global fi nancial system. The authors also examine the concerns and obstacles relating to the introduction of this instrument, suggesting that some may be exaggerated while others could be overcome.

There are significant advantages to Trichet bonds over other discussed solutions to the sovereign debt problem. One such proposed solution is the issuance of “Euro Bonds” guaranteed by the Eurozone countries or the EU itself for the purpose of redeeming sovereign bonds by market purchases, or by lending the proceeds to the countries involved for them to acquire their debt. Apart from the considerable political obstacles to such a program, the undertaking actually makes it less likely that existing self-interested debt-holders will sell in the market.

We propose the creation of “Trichet Bonds” as a comprehensive solution to the current sovereign debt crisis in the EU area. “Trichet Bonds,” to be named after the ECB president Jean-Claude Trichet, will be similar to “Brady Bonds” that resolved the Latin American debt crisis in the late 1980s and were named after the then Treasury Secretary Nicholas Brady. Like the Brady Bonds, Trichet Bonds will be new long-duration bonds issued by countries in the EU area that will be collateralized by zero-coupon bonds of the same duration issued by the ECB.

Bonds are securities that establish a creditor relationship between the purchaser (creditor) and the issuer (debtor). The issuer receives a certain amount of money in return for the bond, and is obligated to repay the principal at the end of the lifetime of the bond (maturity). Typically, bonds also require coupon or interest payments. Since all these payments are determined as part of the contracts, bonds are also called fixed income securities. A straight bond is one where the purchaser pays a fixed amount of money to buy the bond.

The high costs of fighting the wars in Iraq and Afghanistan have rekindled congressional interest in the concept of the sale of a Treasury security to help finance these war costs. In the 111th Congress, three bills have been introduced that would permit the issuance of a war bond: S. 2846, H.R. 4315, and H.R. 4385. Although these bills are silent on any relationship between the proposed “war bonds” and World War II-era war bonds, the question has been raised whether or not the issuance of war bonds during the Second World War serves as a good model for a new “war bond.

This paper estimates the impact of monetary policy actions on bill, note, and bond yields, using data from the futures market for Federal funds to separate changes in the target funds rate into anticipated and unanticipated components. Bond rates’ response to anticipated changes is essentially zero, while their response to unanticipated movements is large and highly significant. Surprise policy actions have little effect on near-term expec- tations of future actions, which helps explain the failure of the expectations hypothesis on the short end of the yield curve....

In addition McQueen and Vorkink (2004) are able to reproduce GARCH volatility using a preference-based model with time-varying sensitivity to news. In a related paper, Vanden (2005) develops a model where the representative agent exhibits a utility function with several risk aversion regimes, which in equilibrium leads to volatility regimes and volatility clustering.

A solution is a homogeneous mixture of solute (present in smallest amount) and solvent (present in largest amount). • Solutes and solvent are components of the solution. • In the process of making solutions with condensed phases, intermolecular forces become rearranged. • Consider NaCl (solute) dissolving in water (solvent): – the water H-bonds have to be interrupted, – NaCl dissociates into Na+ and Cl-, – ion-dipole forces form: Na+ … d-OH2 and Cl- … d+H2O. – We say the ions are solvated by water. – If water is the solvent, we say the ions are hydrated....
