Background: The best method for repairing intertrochanteric fractures is still controversial. The fixation methods includeextramedullary (EM) and intramedullary (IM). Studies that compare IM and EM fixations for unstable hip fractures arerare. In this study, our goal was to compare the efficacy of EM and IM fixation in treatment of unstable intertrochantericfractures.Met...

enzymatic acidolysis of canola oil through caprylic acid was investigated to produce certain medium chain ttriacyliglycerol (tag) structured lipids (sls). lipozyme tl im, an sn-1,3 specific thermomyces lanuginosa lipase, and novozym 435, a non-specific candida antarctica lipase, were utilized as the biocatalysts in a batch reactor. reaction conditions were designed according to taguchi’s approa...

Research on the dynamic behavior of crude oil prices has become a hot issue in recent years. Currently the study of petroleum prices is largely based on the mainstream literature of financial markets whose fundamental assumption is that returns of stock prices follow a normal distribution and price behaviors obey a so-called random walk hypothesis. This notion was first introduced by Bachelier ...

There is no way to predict whether the price of stocks and bonds will go up or down over the next few days or weeks.

These findings, which may seem both surprising and contradictory, were made and analyzed by this year’s Laureates, Eugene Fama, Lars...

In tests of long-term performance, researchers are faced with several research design choices. For instance, when estimating abnormal returns, what specific firm characteristics should be used as matching criteria to select control firms? What weights should be placed on each characteristic? Should an event firm be matched with one control firm or multiple control firms or with a reference port...

Since World War II, the United States has experienced two large booms on the stock market. During the first boom, which lasted from the late 1940s to the mid-1960s, stock returns were clearly leading real activity. Moreover, the evidence also suggests the existence of predictable return variations in the discount rate through time as a response to changing business conditions. Therefore, the fi...
