Is copper an inhibiting factor for primary production in the upwelling waters of Cabo Frio

The goal of the present work was to test the hypothesis that inorganic species of copper may inhibit primary production in upwelling waters from the Cabo Frio region. Water samples were collected from four different depths up to 50 m at three stations of Cabo Frio and nutrient concentration, pH, dissolved oxygen, alkalinity, seston, chlorophyll a, primary production, NPP, copper speciation, Cu(II) and Cu(I) and complexing capacity were determined. The results indicate that the rate of photosynthesis in nutrient rich waters with higher copper content and lower complexing capacity is significantly reduced. Cu(I) made up 2-15% of the total copper, however, there was no evidence to suggest that the photochemical production of Cu(I) affects NPP.
19th INTERNATIONAL CONGRESS ON ACOUSTICS MADRID, 2-7 SEPTEMBER 2007 WAVE APPROACH MODELING OF SANDWICH AND LAMINATE COMPOSITE STRUCTURES WITH VISCOELASTIC LAYERS

Damped multilayer structures such as flat panels are largely used in automotive and aerospace constructions. The modeling of thick composite laminate and sandwich plates and beams with linear viscoelastic treatments is addressed here. Two models are described, validated and compared: discrete laminate method and spectral finite elements method. The first approach assumes each layer as thick laminate with orthotropic orientation, rotational inertia and transversal shearing, membrane and bending deformations. The second approach uses spectral finite elements. A one-dimensional finite-elements mesh is used to describe the crosssection behaviors of the laminate. It is showed that both approaches accurately estimate the propagative wave solutions of laminated structures. The models are successfully compared to classical finite elements and experimental results for different boundary conditions. Moreover, the equivalent damping loss factor of composite laminate plates with viscoelastic treatment is addressed and the heading direction influence is discussed.
THE MANAGEMENT TEAM: A KEY ELEMENT IN TECHNOLOGICAL START-UPS

This longitudinal study of new, technology based ventures studies how a founding team influences the organization choices, processes and ultimately the success or failure of the venture. The functional breadth of the founding team and the strenght of the CEO are related to the success of the venture. Their influence is primarily through the initial selection of a product. Beyond that all companies in our sample, regardless of team breadth or CEO strength, follow similar organizational processes and conduct their missions effectively. The failure of the initial product is an irreparable blow, from which a successful recovery is unlikely. 1 Professor, Stanford University 2 Professor, Entrepreneurship, IESE
IDENTIFICATION AND CULTIVATION OF MFW 23-08 ISOLATED FROM MARINE SPONGES FOR BIOACTIVE COMPOUND PRODUCTION

Production of marine bioactive compound for commercial usage has been hampered due tothe problem of raw material supply. To overcome this, marine microbes especially those associatedwith the bioactive-compound producer biota, has been explored as bioactive sources, with severaladvantages such as shorter production time, cheaper production cost and avoiding over exploitationof marine biota sources. Previous research showed that fungi MFW 23-08 was one of the potentialisolates from Wakatobi sponges which produced bioactive compounds that was active againstbreast cancer cell line and as antioxidant. This study was intended to identify MFW 23-08 andoptimize the production of its bioactive compound through optimization of MFW 23-08 culture.Culture optimization was conducted using 3 liquid media, i.e. malt extract broth (MEB), glucosepeptone yeast (GPY), and minimal fungal media (MFM), and cultivation periods, i.e. 2, 4, 6, 8, and10 wk. Results revealed that MFW 23-08 crude extract of 2 wk-MFM cultivation, at the concentrationof 30 μg/ml, was able to retard 87% breast cancer (T47D) cell growth. While at concentration of100 μg/ml, the 6 wk. MEB cultivated extract was able to hamper free radicals (56%). However, thecrude extract from MFM media cultivation, in the concentration of 50 and 100 μg/ml was not able toinhibit Escherichia coli and Staphylococcus aureus growth. Based on molecular identificationusing ITS1-ITS4 primers, MFW 23-08 isolate was 99% similar to Penicillium citrinum, P.griseofolvum and Penicillium sp.
Review on Generating Private Recommendations Using Elgamal Homomorphic Encryption

User’s private or sensitive data can be misused because of curious administrators in online applications. Traditional ways of protecting data involve security of user’s privacy against third party but not from the service provider. To protect user’s data we present an encryption technique and generate recommendations. Recommendations are generated by processing data under encryption. Generating recommendations have become an important research area for the purpose of user’s privacy. By introducing a multiparty computation technique (MPC) the active participation of user can be eliminated, system can secure user’s private data and by comparing similarities generate recommendations.

Surface Characterization of Dilute Acid Pretreated Populus deltoides by ToF-SIMS

Time-of-flight secondary ion mass spectrometry (ToF-SIMS) was used to analyze the molecular constituents on cross sections of juvenile poplar (Populus deltoids) stems before and after dilute acid pretreatment (DAP). Bulk analysis of milled and 50 μm thick cross sections of poplar before and after DAP was shown to be chemically equivalent by FT-IR and carbohydrate analysis. ToF-SIMS analysis of dilute acid pretreated material indicated significant changes in relative contents of cellulose, xylan, and lignin occurred upon pretreatment. The relative content of xylan after DAP increased by 30% on the surface of the poplar stem by ToF-SIMS, while bulk carbohydrate analysis showed that the relative concentration of xylose decreased 10-fold in comparison with untreated poplar wood. The relative content of cellulose and G-lignin units doubled on the surface of the poplar stem sections, while the bulk glucose concentration and Klason lignin increased 40% and 5%, respectively, as determined by bulk carbohydrate and.
Identification of Targetable Virulence Factor and Drug Screening For Bacterial Pneumonia

Pneumonia is an infectious disease. This is prevalent in pandemic proportions across the Globe; especially in developing countries. It is one of the major causes of morbidity and mortality among infants and children. It is mainly caused by bacterial or viral infection. Irrespective of the abundant occurrence of bacterial pneumonia, there is no specific antibiotic therapy available. On the other hand non-specific therapies are less effective and may induce bacterial resistance. Therefore, in present work, we explored a common but novel target for four pathogenic pneumonia causing bacteria and also revealed the most specific antibiotic(s) to this target.We observed trigger factor protein as a common targetable virulence factor present in four pathogenic bacteria viz. Streptococcus pneumoniae, Klebsiella pneumoniae, Chlamydophila pneumoniae and Mycoplasma pneumoniae. After screening of 116 available antibacterial compounds, we found 04 most specific and potent antibacterial agents that inhibit the growth and survival of bacteria through trigger factor protein.

T YPOLOGY IN POLLINATION BIOLOGY : L ESSONS FROM AN HISTORICAL CRITIQUE

Typological schemes that describe putative floral adaptations for pollinators have played a central role in pollination biology. In 1882 the prominent German botanist and Darwinist Hermann Müller commented critically on a precursor of modern versions of such “pollination syndromes” that had been developed by his Italian colleague Federico Delpino. Delpino also was a self-proclaimed Darwinist, but in fact adhered to teleology— explanation beyond nature. As a consequence he viewed his typology as reflecting a deeper ideal and thus as rigidly true, and rejected as unimportant any visitors to flowers that it did not predict. Although Müller also classified flowers as to pollinators, he considered such schemes to be fallible, and pondered what diversity and variation in floral visitors might mean. Müller’s comments, which we translate here, are of interest given that appeals to teleology have resurfaced from time to time in discussions of pollination syndromes, and more importantly because his warning against taking typological schemes too literally remains valid. Typology is a useful tool in biology, including pollination biology, but care must be taken that it does not replace nature as perceived reality.
Evaluating Margins of Safety in Brazed Joints

WELDING JOURNAL Evaluation of strength margins in structural components is a normal practice used in the design of metallic and composite structures. Mechanical, welded, or adhesively bonded joints in such structures are routinely assessed for their load-carrying capabilities in accordance with widely accepted engineering analysis techniques and failure criteria (Refs. 1–5). Brazed joints, however, seem to be an exception. Literature searches for analytical methods of the evaluation with the strength or margin of safety (MS) of complex brazed joints produced no satisfactory results. This is particularly true when the brazed joints are subjected to multiaxial loads. Although this article does not explore the reasons for a lack of books or guides on structural analysis of brazed joints, it would be beneficial to mention several factors commonly identified by designers as stumbling blocks precluding them from a comprehensive analysis of the brazed joints. These factors are as follows: • Lack of knowledge of the mechanical properties of the brazed joint filler metal interlayer; • Uncertainty of how to use these properties even if they, somehow, are made available; • Inadequate attention to the analysis of the brazed joints from the structural professional community and academia as compared with other methods of assembly such as welding, adhesive bonding, or fastening; • Lack of techniques to account for defects commonly found in brazed joints like incomplete fill or trapped salts; and • Nonstandard joint configurations that have not been tested to validate analytical models. It is quite clear that these factors offer challenging problems to metallurgical, materials, and mechanical engineers in terms of understanding the interaction between the filler and the base metals, experimental techniques of measuring mechanical properties of the joints, as well as the appropriate interpretation of the results. This article deals with the issues that fall within the second factor mentioned previously. Many challenges exist in the analytical modeling of the braze joint. The foremost difficulty is that braze joints are normally very thin (less than a hundred microns thick) compared to their lateral dimension. This disproportionally large aspect ratio not only makes the analytical calculation of the stress and strain incredibly difficult but also, most importantly, changes the fundamentals of the failure mechanism of a ductile material.

Information Transmission In Elimination Contests

I consider a two-stage elimination contest with uninformed and informed players. Informed players can signal their type to future uninformed opponents through their efforts in the first stage. Relative to the benchmark case of complete information, I find that an informed player exerts a higher effort in stage 1, if the uninformed future opponent is weaker than him. Conversely, he exerts a lower effort, if the uninformed opponent is stronger than him. This result is consistent with a conjecture in Rosen (AER, 1986). Intuitively, informed players may want to scare future uninformed opponents by exerting higher efforts in earlier rounds. However, trying to scare a stronger player may not be a sensible strategy because he might compete very fiercely. In equilibrium, informed players who are stronger than uninformed players separate from informed players who are weaker than uninformed players. This result differs from Horner and Sahuguet (2003) where stronger informed players pool with weaker informed players.
Improving E-Trade Auction Volume by Consortium

Agent-based auction trading plays an important role in the electronic acquisition of products/service for organization or e-procurement, especially for MRO materials. Effective agent-based trading has multiple benefits, such as reducing inventory levels, and a dual impact of centralizing strategic procurement objectives while decentralizing the operational procurement processes (Puschmann and Alt, 2005). aBstract
The role of conductive dopants in polymer cholesteric liquid crystals

Abstract Variety of conductive dopants were used to modify the electric properties of polymer cholesteric liquid crystals. Different types of carbon blacks, carbon nanotubes, as well as metallic particles were used as conductive dopants in this work. All of them affected the conductivity of the polymer matrix, but at different dopant concentrations. The percolation threshold behaviour of used dopants in the polymer host showed pronounced dependence on the dopants’ particle size and particle shape anisotropy. For instance, the higher the aspect ratio of carbon-based dopant particles (aspect ratio = length : diametar), the lower the percolation threshold; while increase in metallic dopants' diameter yielded higher percolation threshold of polymer composition.
An Assessment of Cultural Factors Affecting Insurance Uptake: A Survey of the Nairobi Central Business Districts

Purpose: the purpose of this study was to establish the effect of cultural factors that affect the uptake of insurance in Nairobi central business district, Kenya. Methodology: The study employed a descriptive research design. Primary data was used in the study and was gathered using a questionnaire. The target population for the study was the existing and potential insurance customers within the Nairobi CBD. The study targeted a population of 160 respondents and a sample of 100 respondents was chosen. The main sampling technique that was used for this study is stratified random sampling. Secondary data was collected from books, journals and the internet. The primary data was first coded and organized into themes, categories and patterns. Results: Based on the findings the study concluded that religion has a negative effect on the uptake of insurance in Kenya. Further, cultural taboos and beliefs, cultural attitudes and values language used by insurance sales agents, education have a negative effect on the uptake of insurance in Kenya. Unique contribution to theory, practice and policy: The study recommended that IRA should encourage insurance companies to sensitize the public on the different insurance products available in the market on a regular basis. The IRA and AKI should ensure that all the agents transacting the insurance business are properly trained, licensed and motivated to help reduce the perception that insurance agents are conmen or dishonest. The IRA should embark on a campaign to sensitize the public about the benefits of insurance in a bid to change their attitudes towards taking up insurance covers.
IMPACT OF FOREIGN DIRECT INVESTMENT ON STOCK MARKET DEVELOPMENT: A STUDY WITH REFERENCE TO INDIA

Efficient capital markets are essential for economic growth and prosperity. An integral part of capital market is the stock market, the development of which is linked with the country's level of savings, investment and the rate of economic growth. India’s stock market has been classified as one of the fastest growing markets. India is the biggest and most liquid exchange in India and is a major source of capital formation in India. Local and foreign investor’s confidence in the investment environment of India has boosted the stock market index in recent years. The developing countries are witnessing changes in the composition of capital flows in their economies because of the expansion and integration of the world equity market. The stock markets are also experiencing this change. Foreign direct investments (FDIs) are becoming important source of finance in developing countries including India. The paper investigates the impact of FDI on the stock market development of India. The key interest revolves around the complementary or substituting role of FDI in the stock market development of India. The study also examines the other major contributing factors towards the development of stock market. An ARDL bound testing approach is used for long-run relationship among variables and the error correction model is used for short run dynamics. Our results support the complementary role of FDI in the stock market development of India. Other macroeconomic variables affecting stock market development are domestic savings, GNP per capita, and inflation.
A model for hybrid simulations of molecular dynamics and computational fluid dynamics

We develop a method for multiscale hybrid simulations of molecular dynamics (MD) and computational fluid dynamics (CFD). In this method, the usual lattice-mesh based simulations are applied for the CFD level, but each lattice is associated with a small MD cell that generates a “local stress” according to a “local flow field” given from CFD instead of using any constitutive functions at the CFD level. We carried out hybrid simulations for some elemental flow problems involving simple Lennard-Jones liquids and compared the results with those obtained by usual CFD with a Newtonian constitutive relation in order to examine the validity of our hybrid simulation method. It is demonstrated that our hybrid simulations successfully reproduce the correct flow behavior obtained from usual CFD as long as the mesh size Δx and the time step Δt of CFD are not too large compared to the system size lMD and the sampling duration tMD of MD simulations performed at each time step of the CFD. Otherwise, the simulations are af.

APHASIE HANDICAP SCORE

L'accident vasculaire cerebral (AVC) est la principale cause de handicap de l'adule dont la quantification est indispensable a l'evaluation de la qualite des soins. Le score de Rankin est un " best-seller " qui a contribue a demontrer l'efficacite de la thrombolyse. Ce score global du handicap est simple et le plus " patient-oriente " des scores actuels. Il nous a semble interessant d'adapter cette approche globale du handicap post-AVC au probleme specifique des aphasies. L'objectif etait de disposer d'un outil simple, unique et reproductible du retentissement de l'aphasie sur la vie du patient, quelque soit le type d'aphasie. L'Aphasie Handicap Score (AHS) a ainsi ete concu aux Urgences Cerebro-Vasculaires de la Salpetriere. Il classe les patients en 5 categories selon quelques criteres dont les plus importants sont : persistance d'un langage vecteur de communication, handicap resultant de l'aphasie. Nous avons teste sa reproductibilite inter-observateur chez 71 patients a la phase initiale de l'AVC. Nous avons ensuite correle les resultats de l'AHS a ceux de l'Echelle de Communication Verbale de Bordeaux (ECVB) et de la fluence verbale au cours de 182 consultations chez 84 aphasiques chroniques. A la phase initiale de l'AVC, la reproductibilite de l'AHS est bonne (k pondere = 0,71). Lors du suivi en consultation, l'AHS est fortement correlee a l'ECVB (R = -0,89) et a la fluence (R = -0,67). L'analyse discriminante montre qu'il existe des valeurs seuils significatives de score ECVB et de fluence correspondant aux principales categories d'AHS. CONCLUSION : l'AHS est un outil " patient-oriente " d'evaluation du handicap resultant d'une aphasie. Il est aussi rapide et accessible au neurologue que le score de Rankin. Sa reproductibilite est satisfaisante des la phase initiale de l'AVC, et il est correle a la fluence semantique et a l'ECVB. Ces resultats suggerent que l'AHS peut etre considere comme un equivalent du Rankin dans le domaine de l'aphasie et pourrait donc devenir un outil d'evaluation et de recherche therapeutique interessant.
