It is one of the two targets of the MoMAR (Monitoring the Mid Atlantic Ridge) project patronized by InterRidge, and is the focus of an IODP drilling project. What makes this site exceptional is the abundance of natural hydrogen, methane, and iron, an element which plays a major role in active processes, down to the scale of molecules. During Cruise MomarDream (25 Aug. - 15 Sept. 2008), R/V L'Atalante and ROV Victor spent 3 weeks on site Rainbow to carry out detailed investigation of this unique area. The goals of the cruise were, first, to study the role of iron in the geological, hydrological, and biological processes, and second, to identify potential drilling targets. Beyond the requirement of a "zero state" for the repeated observations and in fine the site monitoring in the framework of the MOMAR project, the completion of an exhaustive inventory of the biological populations is needed for the sake of preservation of a fragile environment. Multibeam bathymetry and magnetics have been collected by ROV Victor 50 m above the seafloor on a 4 km × 3 km wide box centered on the site and covering about 25% of the Rainbow Massif. Similarly, multibeam bathymetry, magnetics, and high resolution photographs have been acquired 10 m above the seafloor on a 650 m × 500 m box centered on the site, and on a 300 m × 300 m box centered on a field of dead clams. A nearly full coverage was obtained in these boxes. Direct geological exploration was also carried out and allowed the collection of rock samples, complemented by an intensive dredge program when the ROV was onboard. A large part of the cruise was devoted to biological studies sensu lato, including the collection of fluids dedicated to the study of abiotic organic molecules and metagenomics, the collection of sulfide for microbiological investigations, in situ chemical measurements to characterize the hydrothermal environment, the collection of shrimps and mussels, and the deployment and recollection of colonization modules. As for the initial geological results, the microbathymetry and the rock sampling are presented in two posters (Gente et al.; Ildefonse et al.). A very strong positive magnetic anomaly is clearly associated to the site and likely reflects the strong magnetization of serpentinites impregnated by sulfides. Another strong positive anomaly corresponds to a zone of similar size located 500 m south of Site Rainbow, and may correspond to a fossil site, as suggested by tenuous evidences from rock samples collected in this area.

The bathy-metric image is considered as set of oriented wave profiles generated, in general, by unidirectional currents (water flows constantly in one direction) where each profile can be viewed as the superposition of fast oscillations (ripples) and slow oscillations (sand waves). Due to the texture and multicomponent aspects of the bathymetric image, the characterization is performed using an adaptive mutliresolution decomposition based on the multivariate empirical mode decomposition (MEMD) technique. The MEMD a data driven technique, well dedicated for non-stationary and multicomponent data analysis, is applied to multivariate bathymetric profiles to generate 2D intrinsic empirical functions (IMFs) or empirical images each one associated to a bedform such as ripple, sand wave or dune (migaripple). Preliminary results on real bathymetric images shows the interest of the MEMD as a feasible decomposition tool to identify main bedforms.

The research aims to identify the implementation process of TQM, and its influence toward the quality of human resources. The result showed the variables of TQM (that is, employees role, employer role, relations of employer and employees, organizational aspects, and environ employees, organization aspects, and environmental aspects) are simultaneously have a significant influence toward the quality of human resources in PR. HF Prima Malang. The organizational aspects variable is dominantly influence the corporate's quality of human resources.

This studi used data from financial statement of the state own companies, This study also used thirteen companies as sample. Field research was applied, data collection uses documentation technique. There is one statistical analysis used in this study, that isPartial Least Square(PLS).Parcial Least Squareis used to analyse five variables, those are Investment Opportunity Set (IOS), Financial Policy, Capital Structure, Risk and Financial Performance. The result of this study found that, Investment Opportunity Set influence Risk during 1998-2005. The result also show that Capital Structure do not influence Financial Performance. But, Financial Policy is significance influencing Financial Performance. Finally, the result of the study indicate that financial policy influence Financial Performance of company. Key words : Capital Structure, Investment Opportunity Set, Financial Policy, Risk and Financial Performance.

Working capital turnover variable is calculated using the Working Capital Turnover ratio, liquidity is measured using Current Ratio, solvency is measured using Debt to Assets Ratio and Profitability is measured using Return on Assets. This type of research is quantitative using the classic assumption test, multiple linear regression analysis and partial test. The sampling technique uses the purposive sampling method. The results of the analysis that have been done, show that the working capital turnover, liquidity and solvency significantly influence the profitability of the company. This is evidenced by the results of correlation analysis which shows the value of r = 0.831 which means there is a strong relationship between working capital turnover, liquidity and solvency to ...
