three hundred twin births from a hospital in tehran, iran have been analyzed for seasonal variation at birth and physical measurements. the results show that the highest twinning rates for mm (5.61), ff (7.73) and mf (5.36) were seen in april, january and september, respectively. the four physical measurements at birth showed non-significant differences among the male and female twins, but mm a...

a experiment was lay out in order to evaluate the effects  of different biofertilizers on yield and yield components of maize at the lorestan provience, iran. the experiment was a factorial design with three replications. treatments were three nitrogen biofrtilizers (nitrokara (n1), o4 (n2), o6 (n3) and control (n4)) and three phosphate biofrtilizers (phosphate barvar2 (p1), biozarr (p2), mc1+p...

studies show that any complications including hemorrhage, lack of blood supply, lack of oxygen supply, and death of cells in a tissue, will have a clear effect on electrical properties of that tissue. thus, by measuring impedance of a set of tissues, potential problems of the damaged tissue may be found. since electrical impedance is closely related to the measuring frequency, obviously, every ...

− The Real-time Colored Petri Net (RTCPN), a modification of traditional Colored Timed Petri net, is proposed to describe virtual factory. In RTCPN, firing discipline differs from traditional way in that the concept of time-enabled transition is introduced to implement real-time simulation. In this paper, we address how to describe virtual factory using RTCPN model. Combined with block diagram,...

Polybrominated diphenyl ethers (PBDEs) along with hydroxylated polybrominated diphenyl ethers (OH-PBDEs) and methoxylated polybrominated diphenyl ethers (MeO-PBDEs) were found in plant and soil samples collected surrounding a seafood processing factory and a seafood market in China. The profiles of MeO-PBDE congeners were different between seafood processing factory and seafood market. The dete...

The main objective of this paper is to study the Distributed Scheduling (DS) problems in Flexible Manufacturing System (FMS) environment using simulation model. This FMS is assumed to be single factory and multi factory which are analyzed by production capacity, throughput, utilization and work-in-process (WIP) by considering scheduling rules. The rules which are includes Largest processing tim...

People believe they experience the world objectively, but research continually demonstrates that beliefs influence perception. Emerging research indicates that beliefs influence the experience of eating. In three studies, we test whether beliefs about how animals are raised can influence the experience of eating meat. Samples of meat were paired with descriptions of animals raised on factory fa...

Our research activities in the eld of federated database systems (FDBS) are closely related to the SIGMAFDB-project which is founded by the German state Sachsen-Anhalt since 1995. In this extended abstract, we present our view on federated database systems and sketch some of the main results of the work of our group. We brie y discuss di erent research aspects and implementation activities. Due...

The B factories continue to dominate experimental publications on the τ. Since the previous edition of this Review, there have been 15 published papers that have contributed measurements to the τ Listings, including 6 from the BaBar Collaboration and 8 from the Belle Collaboration. Seven of these papers have provided new upper limits on the branching fractions for neutrinoless τ-decay modes. Of...
