The fusion and evaporation residue cross sections for the 50Ti+249Cf and 54Cr+248Cm reactions calculated by the combined dinuclear system and advanced statistical models are compared. These reactions are considered to be used to synthesize the heaviest superheavy element. The 50Ti+249Cf reaction is more mass asymmetric than 54Cr+248Cm and the fusion excitation function for the former reaction i...

The green fluorescent protein (GFP) of Aequorea victoria is frequently fused to other proteins to serve as a reporter for gene expression or the localization of proteins in vivo. We report that when a GFP fusion protein is translated in vitro under standard conditions, the GFP portion folds efficiently and becomes fluorescent. This provides a convenient method for monitoring in vitro translatio...

in this study, mutant forms of bacillus thuringiensis spp. israelensis (h14) were produced. these mutants were identified when the cells were cultured on chloramphenicol plates and stained with crystal violet. protoplasts of the mutants were isolated by enzymatic digestion (lysozyme) of the cell walls at the presence of an osmotic stabilizer. the protoplasts were induced to fuse to each other i...

fusion is an anomaly manifested in both deciduous and permanent dentitions. fu- sion of dental tissues in the primary dentition is of clinical significance owing to the challenges in treatment of the affected teeth and aberrations encountered in development and eruption of their successors. triple tooth refers to the :union: of three separate tooth entities. it can occur by fusion, germination,...

original article   mental fatigue (mf) is considered as a contributor factor in incident, even catastrophic one. electroencephalography measurement has been the most acceptable method to assess mf by neurologists. however, this method could be hardly feasible in real work setting. flicker fusion device, by contrast, is more usable at work setting. the purpose of this study was to compare the cr...

background: controlling the hemodynamic situation of patients who have spinal operation is of prime importance, and maintaining the heart rate and blood pressure in normal or low- normal levels in these patients can reduce their bleeding loss. one of the commonly used drugs for this purpose is remifentanil. another sedative-hypnotic-analgesic drug, with acceptable effects is dexmedetomidine. th...

Extending and improving the concepts: woven frame and fusion frames, we introduce the notion of woven fusion frames in Hilbert spaces. We clarify our extension and generalization by some examples of woven frames and woven fusion frames. Also, we present some properties of woven fusion frames, especially we show that for given two woven frames of sequences, one can build woven fusion frames and ...

Recent highly reproducible results of tritium production by deuterium-deuterium (D-D) fusion from gas/solid-state fusion experiments are discussed in terms of a surface fusion mechanism. Theoretical criteria and experimental conditions for improving and optimizing D-D fusion rates in a gas/solid-state fusion device are described. It is shown that the surface fusion mechanism also provides a pla...

The spike glycoproteins of Semliki Forest virus mediate membrane fusion between the viral envelope and cholesterol-containing target membranes under conditions of mildly acidic pH (pH < 6.2). The fusion reaction is critical for the infectious cycle, catalyzing virus penetration from the acidic endosome compartment. To define the role of the viral spike glycoproteins in the fusion reaction, conf...

Executive Summary Princeton Satellite Systems and the Princeton Plasma Physics Laboratory (a Federally-Funded Research and Development Center) are collaborating on a breakthrough concept, the Direct Fusion Drive (DFD), a D – 3 He fueled fusion-powered rocket engine. The design is based on the Princeton Field-Reversed Configuration Reactor (PFRC) concept for a compact, clean, steady-state fusion...
