A system approach to safety case study

I firmly believe every safety professional is fully committed and engaged in a myriad of programs and processes to minimize to the maximum extent possible, injury and illness which occur in our work environments. At our very core as safety professionals we are humanitarians at heart. Our goal is both simple and complex: to ensure each and every employee goes home safely to their families and ...

Laboratory study on the impact of pH and salinity on the fluorescence signal of Natural Organic Matter (NOM) relevant to groundwaters from a Canadian Shield sampling site

Fluorescence spectroscopy with the spectral resolution routine PARAFAC is a leading tool to analyze Natural Organic Matter (NOM) in waters. This routine resolves spectra into humic-, fulvic- and protein-like components, which helps interpret the NOM dynamics in environmental systems. This work is one of the first systematic studies dealing with the impact of chemical perturbations on the ...

Lead in Christmas Lights

A recent California proposition led to awareness that lead is a stabilizer in the Polyvinyl Chloride (PVC) jacketing that covers conductors in Christmas lights. The objective of this study is to examine the level of accessible lead in Christmas lights. Following U.S. Environmental Protection Agency (U.S. EPA) Lead Inspectors’ procedures, researchers at Cornell University and in Nebraska conducted ...

How can established firms survive technological discontinuities? A case study on the Japanese rechargeable battery industry

Quite a number of established firms lose their momentum during the transition phase from a conventional technology to a new technology. How can established firms recover? We attempt to explore this question through a comparative case study analysis in the Japanese rechargeable battery industry. We extensively examine Sanyo, an established firm which recovered after a technology transition, by ...

A network analysis of transboundary water cooperation in La Plata Basin

When do countries cooperate in transboundary waters? One of the largest in the world, the La Plata Basin covers part of Argentina, Bolivia, Brazil, Paraguay, and Uruguay. These five countries co-manage the basin through a network of legal agreements, domestic and international organizations, and cooperative projects. In this paper, we examine the network structure of cross-national water ...

Chapter 4: three industrial revolutions

The management and prevention of technological risks and failures pose various industrial, political and theoretical challenges. This is due to the fact that the increasing complexity of technological systems invariably leads to increasing risk, especially when scientists and engineers are constantly pushing the limits of technological knowledge, harnessing vast forces of nature without full ...

Liquid crystal display industry in Taiwan

This paper presents an overview of Taiwan's LCD (liquid crystal display) industry to illustrate the emergence of competitive advantages of Taiwan's high-tech development. It shows that Taiwanese firms are evolving from manufacturing labour-intensive items of LCDs to more technology-intensive TFT LCD. The worldwide LCD demands are growing at a fast pace and Japan leads both in technology and ...

A Potential New Health Risk From Lead in Used Consumer Products Purchased in the United States

The Lead Renovation, Repair, and Painting Rule and the Consumer Product Safety Improvement Act, both enacted in 2008, were intended to protect children from exposure to lead by setting federal limits on lead content. Neither of these federal actions, however, addresses a newly recognized pathway of exposure to lead from the use of used consumer products in the home. In the study described in this ...

Investigation of adsorption capacity of <italic>N</italic>-carboxymethyl chitosan for Pb(II) ions

Investigation of adsorption capacity of N-carboxymethyl chitosan for Pb(II) ions

N-carboxymethyl chitosan (NCMC) was prepared by reacting chitosan (CTS) with chloroacetic acid and characterized by 13C-NMR spectroscopy to confirm that carboxymethylation occurred only in the amino groups. The adsorption properties of CTS, NCMC and O-carboxymethyl chitosan (OCMC) towards Pb(II) ions were evaluated and the order of the adsorption capacity was as follows: NCMC > OCMC ...

Probing nanoscale thin films by phase sensitive neutron reflectometry: a simulation study

Neutron reflectometry is a powerful tool for research in nanostructure materials. It is a powerful technique for investigating surfaces and interfaces, thin films, nanostructure materials, biomembranes and magnetic films. Here, by a simulation model, we show that how it can be used to probe the nano material thin films. It is shown that by knowing the information of the complex reflection ...

Determining the causality relationships among FDI determinants: evidence from Jordan

Economic theory suggests that FDI reinforced economic growth leading to economic development. The present paper analyses four macroeconomic factors that are affecting FDI inflows in Jordan. However, it examines the long–run and short–run causality relationships among inflation rate (INF), gross domestic product (GDP), broad money supply (M2), exchange rate (EX) and FDI inflows for the (1980–2011) ...

Sorption of lead ions from aqueous solution onto Enterococcus faecium biomass

This study reports kinetics and equilibrium of lead sorption onto the biomass of Enterococcus faecium. E. faecium is a lactic acid bacterium and was isolated from meat. Batch experiments were carried out to analyze the effects of the initial lead concentration, initial pH of the medium, agitation time and temperature on the biosorption. The lead sorption was found to increase with the increase ...
