3-(2-Hydroxyphenyl)-6-(4-nitrophenyl)-7H-1,2,4-triazolo[3,4-b][1,3,4] thiadiazine, C 16H 11N 5O 3S, was prepared by the cyclization of 3-(2-hydroxyphenyl)-4-amino-5-mercapto-1,2,4-triazole with 2-bromo-4-nitroacetophenone. The compound was characterized by means of elemental analysis, IR, 1H NMR, 13C NMR, mass spectrometry, and X-ray diffraction. The compound crystallizes in a monoclinic system with space group C c, a=2.1853(4) nm, b=2.1192(5) nm, c=1.3526(3) nm, β=95.21(2)°, V=6.238(2) nm3 , D calcd.=1.505 Mg/m3, Z=16, F(000)=2916, R 1=0.0501, wR 2=0.0427. A comparison between the crystal structures of 1,2,4-triazolo[3,4-b] [1,3,4] thiadiazine and 1,2,4-triazolo[3,4-b][1,3,4] thiadiazole was made in the structural view. A two-dimensional network is formed by hydrogen bonds and π-π stacking interactions.

Component commonality has been cited as a powerful approach for manufacturers to cope with increased component proliferation and to control inventory costs. To fully realize its potential benefits, one needs a clear understanding of its impacts on the system. In this paper, the feasibility of using a simulation model to provide a systematic perspective for manufacturing firms to implement a commonality strategy is demonstrated. Alternative commonality strategies including the stage of employing commonality and the allocation policies are simulated. Several interesting results on effects of commonality, allocation policies, and optimal solutions are obtained. We then summarize qualitative insights and managerial implications into the component commonality design and implementation, and inventory management in a general multi-stage assembly system.

In order to research multi-component ion beam transport process and improve transport efficiency, a spe- cial simulating program for ECR beam is becoming more and more necessary. We have developed a program written by Visual Basic to be dedicated to numerical simulation of the highly charged ion beam and to optimization of beam dynamics in transport line. In the program the exchange of electrons between highly charged ions and low charged ions or neutral atoms (residual gas in transport line) is taken into account, adopting classical molecular over-barrier model and Monte Carlo method, so the code can easily give the change of charge state distribution along the trans- mission line. The main advantage of the code is the ability to simultaneously simulate a large quantity of ions with different masses and charge states, and particularly, to simulate the loss of highly charged ions and the increase of low charged ions due to electron exchange in the whole transport process. Some simulations have been done to study the transmission line of LECR3[1] which is an ECR ion source for highly charged ion beam at IMP. Compared with ex- perimental results, the simulations are considered to be successful.

Effects of basal mediums, hormones and their concentrations on the shoot regeneration fromleaf of sweet persimmon (Diospyros kaki Thunb. cv. Uenishiwase) were studied by orthogonaldesign trial. The result showed that modified Murashige and Skoog [MS (1/2 N)] was the mostoptimum for the regeneration and 1/2 MS was better than MS. Shoot percentage in the mediumcontaining 4.0 mg L-1 ZT(zeatin) was much higher than that of other two concentrations, amongwhich 2.0 mg L-1 ZT was much better than 1.0 mg L-1 ZT and shoot percentage in the concentrationof 1.0 mg L-1 ZT was only 4%. There were no any beneficial effects when supplementing IAA in themedium. Shoot percentage and average shoots per explants were dramatically decreased in the 2.0 mgL-1 IAA. Data in the orthogonal trial indicated that ZT was the most effective factor in theshoot regenerating of Uenishwase persimmon and basal medium was important too, but IAA had noany beneficial effects at all. In the orthogonal trial, the best result was achieved in MS (1/2 N) medium containing 4.0 mg L-1 ZT and 1.0 mg L-1 IAA, in which shoot percentage and averageshoots per explants were 86% and 2.2, respectively.

It is reported that there exist deformable media which display quantum effects just as quantum entities do. As such, each quantum entity usually treated as a point particle may be represented by a deformable medium, the dynamic behavior of which is prescribed by four dynamic state variables, including mass density, velocity, internal pressure, and intrinsic angular momentum. In conjunction with the finding of the characteristic equation characterizing the physical nature of such media, it is found that a complex field quantity may be introduced to uncover a perhaps unexpected correlation, i.e., the governing dynamic equations for such media may be exactly reduced to the SchrSdinger equation, from which the closed-form solutions for all the four dynamic state variables can be obtained. It turns out that this complex field quantity is just the wavefunction in the SchrSdinger equation. Moreover, the dynamic effects peculiar to spin are derivable as direct consequences. It appears that these results provide a missing link in quantum theory, in the sense of disclosing the physical origin and nature of both the wavefunction and the wave equation. Now, the inherent indeterminacy in quantum theory may be rendered irrelevant. The consequences are explained for certain long-standing fundamental issues.
