Azo-azulene derivatives for nonlinear optical applications

Organic materials are of high interest and are widely used for the development of new powerful and low dimensional technologies. They exhibit several advantages with respect to inorganic compounds such as large cubic and quadratic optical nonlinearities, flexibility, easy manufacturing and so on. Among them, some present abilities for photonic or nonlinear optical applications. Intensive researches have been performed these latest decades to synthesize highly efficient and optically active molecules because of the miniaturization of optoelectronic devices. Azo-azulene derivatives are an interesting class of organic molecules for potential applications in optoelectronics and optical data storage due to their polyfunctional properties. We discuss second and third order nonlinear optical properties of a series of azo-azulene compounds in solid state. Thin films were prepared by incorporating these molecules in a polymethylmetacrylate (PMMA) matrix and were investigated. Moreover, potential usage of these guest-host systems for optical data storage is also discussed

PHYSICAL-CHEMICAL CHARACTERIZATION OF SOME GREEN AND RED MACROPHYTE ALGAE FROM THE ROMANIAN BLACK SEA LITTORAL

Algae are a group of organisms, Thallophytes, containing specific bioactive compounds (i.e. brominated phenols, heterocyclic oxygen compounds, sterols, terpenes, polysaccharides). Their excessive growth has negative consequences on marine organisms; on the other hand, they have a crucial role in food, pharmaceuticals, cosmetics, agriculture. In this paper were studied the main physical-chemical characteristics correlated with the biological specificity of three species of multicellular algae, Enteromorpha intestinalis and Ulva rigida (green), Ceramium rubrum (red), frequently encountered along the Romanian Black Sea coast. Generally mixtures of thallophytes algae from the Black Sea were collected, processed and characterized. Density, pH, conductivity, anions, loss on drying, ash, total nitrogen, protein, lipids, carbohydrates, carotenoids were determined. The results emphasized the possibility of using these marine resources as biofertilizer in agriculture

Photoinduced Gratings in Functionalized Azo-Carbazole Compounds in Picosecond Regime

We report results of diffraction grating inscription on thin films prepared from epoxy resin doped with azo-carbazole based dyes. Diffraction gratings were recorded at the wavelength 532 nm and monitored through intensity of first order of diffraction (632 nm). Atomic force microscope scans of the gratings show that a surface relief grating also appeared

Health Service Use and Expenditure Patterns of Dual Eligibles in Michigan

Objective: The objective is to provide a statewide population-based comparison of Michigan beneficiaries dually eligible for Medicare and Medicaid (duals) to Medicare-only beneficiaries, including the public health expenditures by service type, and to focus on the LTC service use patterns of elderly duals receiving care in various settings. Data Sources: Data sources were linked 2005 and 2006 individual Medicaid and Medicare claims from all Michigan duals. Methods: CMS provided Medicare claims and beneficiary data. Michigan Department of Community Health provided Medicaid claims data. Design: We compared characteristics and health expenditures across various categories of beneficiaries and LTC care settings. Principal Findings: The 13% duals accounted for 33% of total Medicare and Medicaid expenditures. Eight percent of elderly beneficiaries were duals in 2005, accounting for 26% of public health expenditures in the aged. The average monthly expenditures of elderly duals were: $4,896 in institutional LTC,$2,921 for those served through HCBS waiver programs, and $1,488 for those in the community. Conclusions: Duals in Michigan account for a disproportionate large share of state and federal health expenditures. Michigan’s experience suggests that LTC services can be offered in home and community-based settings, at lower costs compared to institutional LTC. The shift in prescription drug coverage from Medicaid to Medicare increased the drug expenditures for some duals and had limited impact on overall dual expenditures. Results may be pertinent within the context of impending healthcare reforms

Variational Approaches to Characterize Weak Solutions for Some Problems of Mathematical Physics Equations

This paper is aimed at providing three versions to solve and characterize weak solutions for Dirichlet problems involving theLaplacian and the -pseudo-Laplacian. In this way generalized versions for some results which use Ekeland variational principle, critical points for nondifferentiable functionals, and Ghoussoub-Maurey linear principle have been proposed. Three sequences of generalized statements have been developed starting from the most abstract assertions until their applications in characterizing weak solutions for some mathematical physics problems involving the abovementioned operators

ISBN 978-9975-147-93-4 (PDF).Due to the tax implications, the income recorded in the accounting of a commercial company requires particularly high attention from managers and accountants. The difference between income and expenses recorded in accounting represents accounting profit. To calculate the fiscal profit, rules are followed that have varied over time with the legislative changes related to the calculation of the profit tax. In addition to their fiscal importance, revenues provide, through their economic analysis, important information about how the unit's resources were used and about the results obtained.
