The hepadnavirus encapsidation signal, epsilon (ε), is an RNA structure located at the 5' end of the viral pregenomic RNA. It is essential for viral replication and functions in polymerase protein binding and priming. This structure could also have potential regulatory roles in controlling the expression of viral replicative proteins. In addition to its structure, the primary sequence of this R...

Control of projects is a core issue for organizations. Successful projects, such as information systems projects, enable organizations to develop a superior supply network and enhance the capability of operations management. A few studies have investigated the effects of control on project performance; however, complexity risk has not been integrated into the relationship between control andper...

Comparative genomic analyses are powerful tools that can be used to analyze the presence, conservation, and evolution of protein families and to elucidate issues concerning their function. To deal with these questions, we have chosen the clan CD of cysteine peptidases, which is formed by different protein families that play key roles in plants. An evolutionary comparative analysis of clan CD cy...

Serine proteases are involved in a variety of biological processes and are classified into clans sharing structural homology. Although various three-dimensional structures of SC clan proteases have been experimentally determined, they are mostly bacterial and animal proteases, with some from archaea, plants, and fungi, and as yet no structures have been determined for protozoa. To bridge this g...

Background Several surface based multi-segment foot models have been developed to investigate distal foot function during gait [1,2]. However, the majority of the models have not defined medial and lateral forefoot or midfoot segments. In addition very little, is currently known regarding the coupling of the distal foot segments [3,4]. The purpose of the current study, therefore, was to utilize...

Foot prints or tracks are a common sign of the occurrence of a wildlife species. By understanding the relationship between foot size and other physical dimensions of an individual animal, researchers and managers may be able to remotely and inexpensively extract useful information on the size and age distribution of a population from animal tracks (Piekielek and Burton 1975; Beck 1991), especia...

First Person Shooter Games (FPSG) such as Counter Strike are often the subject of public concern. Surprisingly, there is no published research available about playing these games. We conducted an exploratory Internet survey (n 5 751) in order to gather information about who the players of online first person shooters are, and why they spend time on playing this particular kind of video game. Th...
