In this paper we examine the specificity of the cooperative binding (in the polynucleotide mode) of bacteriophage T4-coded gene 32 protein to synthetic and natural single-stranded ~iucleic acids differing in base composition and sugar type. I t is shown by competition experiments in a tight-binding (low salt) environment that there is a high degree of binding specificity under these (protein-li...

globally excessive consumption of hydrocarbon fuel in transport sector is a serious threat to the civilization due to paucity of fuel in future. also this growing use of vehicles for transport is contributing about 70% of total air pollution and causing environmental and ecological imbalances. thus the worldwide fast depletion of conventional energy resources and impact of emissions on environm...

Abstract—This paper investigates the thermal issue of permanent magnet synchronous generator which is frequently used in direct drive gearless small-scale wind turbine applications. Permanent Magnet Synchronous Generator (PMSG) is designed with 2.5 kW continuous and 6 kW peak power. Then considering generator geometry, mechanical design of wind turbine is performed. Thermal analysis and optimiz...

3C fiber technology advances the performance frontier of practical, high-pulse-energy fiber lasers by providing very large core fibers with the handling and packaging benefits associated with single mode fibers. First-generation fibers demonstrate scaling to > 240 W average power coincident with 100-kW peak power in 1-mJ, 10-ns pulses while maintaining single-mode beam quality, polarized output...

A radio frequency (RF) ion source was designed and developed for neutral beam injector. A RF driver test bed was used with a RF generator with maximum power of 25 kW with 1 MHz frequency and a matching box. In order to study the characteristic of RF plasma generation, the capacitance in the matching box was adjusted with different cases. The results show that lower capacitance will better the s...

We investigate whether the natural orbitals (NOs) minimize kW Uk, where W is a wave function and U is a full configuration interaction (CI) approximation to W in a reduced basis. We will show that the NOs rarely provide the optimal orbitals for U, except when (1) there are only two particles or (2) only one basis function is removed in the case of fermions. Further, we will show that the CI exp...

Design of the buncher cavity for Cornell / JLab ERL project is presented. This is a reentrant spherical copper cavity at a frequency of 1300 MHz. It will be installed between a 500 keV electron gun and superconducting accelerating sections in the injector part of ERL. The cavity has Q of 20,000 and a shunt impedance of 2.1 MOhm. For a design cavity voltage of 200 kV, power dissipated in cavity ...
