Ab initio calculations at HF/6-31G* level of theory for geometry optimization and MP2/6-31G*//HF/6-31G*for total energy calculation are reported for Z-cyclooctene (1). The most favorable conformation of 1 is theunsymmetric boat-chair (1-BC) geometry. Potential energy profiles for two different boat-chair/boat-chairinterconversion processes were calculated. The process via a chair transition sta...

Investigations have demonstrated that ratio of sugars to organic acids affects the particular taste of citrus fruit and carotenoids are essential for prevent of the disease.  It seems that some rootstocks enhance the ripening of fruits and stimulatethe biosynthesis of sugars and carotenoids. The aim of this study was to evaluate the effect of rootstocks on sugars, organic acids andcarotenoids o...

Colorectal cancer (CRC) is one of the most commonly diagnosed cancers and a major cause of cancer death. However, the molecular mechanisms underlying CRC initiation, growth and metastasis are poorly understood. Dragon (RGMb), a member of the repulsive guidance molecule (RGM) family, has been recently identified as a co-receptor for bone morphogenetic protein (BMP) signaling, but the role of Dra...

Repulsive guidance molecule (RGM) family members RGMa, RGMb/Dragon, and RGMc/hemojuvelin were found recently to act as bone morphogenetic protein (BMP) coreceptors that enhance BMP signaling activity. Although our previous studies have shown that hemojuvelin regulates hepcidin expression and iron metabolism through the BMP pathway, the role of the BMP signaling mediated by Dragon remains largel...

motivation is one of those factors affecting the success and quality of athletic performance. however, limited research has been conducted on the motivational traits of iranian athletes. this study aimed at describing the motivational traits of skilled and novice athletes of team and individual sports in some selected sports fields. players of national teams of the individual sports of karate, ...

High precision localization technology is the basis of fine-grained Location-based Service (LBS), such as interactive games, etc. A novel location system named Dragon is proposed, which provides target location in centimeter-level precision with 10Hz refreshing rate. Dragon uses a Fake-spot filtration algorithm to deal with the NLOS measurements and uses Extended Kalman Filtering (EKF) to handl...

Dragon y is an evolving prototype client for Internet Accessible Mathematical Computation (IAMC). Developed in Java, Dragon y is a protocol-compliant end-user client for making mathematical computing readily available on the Web/Internet. Features of Dragon y include remote help, input editing, command template, history, textbook-style mathematical expression display, as well as interactive dis...

There are seven species bearded dragons of which the most common in the pet trade is the inland or central bearded dragon (P. vitticeps). In smaller numbers, the common bearded (P. barbata) and the Rankin's (P. henrylawsonii) have become more widely available and the number of captive-bred animals is slowly increasing. Adenovirus infections have been reported in the common bearded dragon, the R...
