Bioactive compounds produced by microorganisms have focused on in recent years. In particular, novel compounds showing anti-cancer activity have been isolated from marine microorganisms. In this review, we will discuss on the studies of new bioactive compounds derived from marine bacteria with conjunction to anti-cancer activity. This review will provide an information and source for bioactive compounds showing anti-cancer activity, which were derived from marine bacteria.

This paper, based on Krifka (2001), is about the interpretation of quantifiers in questions. I have argued that quantification into question acts is possible for universal quantifiers, as these quantifiers are based on conjunction, an operation that is defined for speech acts. This explains the restriction to universal quantifiers, which are generalized conjunctions. I have developed a type system in which quantification into question acts can be described. I have argued that expressions that scope out of speech acts must be topic, which explains a number of additional observations. I have also discussed embedded questions, which, depending on the embedding verb, may allow for quantification into questions.

The article suggests criteria of dividing transport systems into systems of limited and open access. Possibilities of implementing principles of the open access in conjunction with the adaptive control at the railway transport have been analyzed. The author makes a grounded conclusion that the development of transport systems based on the open access and adaptive control can play a positive role in overcoming the global instability of the economy and form prerequisites of its stable grows.

A new combined isotropic/kinematic and orthotropic hardening viscoplastic model is proposed which can account for not only differential orientations but also preferred orientations of grains in n metal at finite plastic deformations with an introduction of multiple spin (rate of rotation) concept within the general framework of the model, the effects of anisotropy and constitutive spins will be discussed in conjunction with a closed-form solution for simple shear in n rigid-plastic material, which will be used to simulate experimental data of Montheillet, et al. (1984) for fixed-end tortion tests at finite plastic deformations.

Basicities of nine dimethylanilines have been determined in 50, 70, and 90 volume % ethanol, at $25^{\circ},\;30^{\circ},\;35^{\circ},\;and\;40^{\circ}C$. Temperature coefficients were found to be independent of solvent composition, while they showed a linear correlation with basicities of the compounds. Thermodynamic parameters obtained have been used in the discussion of substituent and solvent effects in conjunction with the general equation derived in the preceding papers.

The purpose of this study is to examine the lead-lag relationship between volatility and returns in high frequency stock market data to see the validity of two hypotheses that explain volatility asymmetry. Specifically, wavelet analysis is applied to decompose the volatility process into permanent and transitory components and then each component is investigated in conjunction with returns. The results from cross-correlation analysis between volatility and returns support the leverage effect hypothesis rather than the volatility feedback hypothesis in all cases.

A mathematical model for long-rage water supply planning was formulated as a dynamic plant location problem with network arc capacity expansion, and illustative example was presented. The proposed solution procedure identifies economical construction timings of surface water supply facilities and water conveyence systems and the best water supply operating patterns as well. In this study, we present a heuristic solution procedure using Simulated annealing Method in conjunction with Bertsekas & Tseng's RELAXT-II for the 0-1 integer network problem.

The WLF equation is derived from the theory of rate processes in conjunction with the theory of liquids of significant structures. The empirical parameters in the WLF equation are discussed and compared with the corresponding quantities in the derived equation.

m-Bromonitrobenzene was reduced to m-bromoaniline with a 86∼91% yield by either baker's yeast (Sigma type I) or glucose and baker's yeast in conjunction with glucose. Nitrosobenzene was reduced to aniline in good yields using baker's yeast(Sigma type I) only.

We develop an algorithm for computing a sparse approximate inverse for a nonsymmetric positive definite matrix based upon the FFAPINV algorithm. The sparse approximate inverse is computed in the factored form and used to work with some Krylov subspace methods. The preconditioner is breakdown free and, when used in conjunction with Krylov-subspace-based iterative solvers such as the GMRES algorithm, results in reliable solvers. Some numerical experiments are given to show the efficiency of the preconditioner.
