Keith Crouch This project has identified industries where sub-micrometer beryllium particle control is an issue.
This project is c haracterizing exposures and assessing controls. G aps in current control methods to reduce exposure are being evaluated. Alan Echt Development and evaluation of controls to reduce silica exposures in construction 1 journal article and 3 indepth technical reports A Method for Simultaneous Analysis of Multiple Pesticides Project Officer: The four differing classeswere chloroacetanilide, triazine, phenoxyalkanoic acid and glyphosate and specific pesticides were atrazine, metolachlor, 2,4-D and glyphosate.
Benefits of FCMIA over existing technologies include increased speed, smaller sample volumes, equivalent or better sensitivity andgreater dynamic range. Jamie Bennett Improved understanding of particle loss and leakage in filter cassettes Three journal articles and 2 NIOSH technical reports Improved understanding of exposures and controls for silica Physical Characterization of Ultrafine Particles Project Officer: Andrew Maynard Estimation of the relationship between aerosol mass and surface area during ultrafine aerosol generation Development of a method to estimate aerosol surface area from number and mass concentration measurements Development of a method to depth profile the surface of ultrafine particles using analytical electron microscopy to investigate surface enrichment of elements in welding fume 2 published papers, 1 in preparation Applied Monitoring Studies Project Officer: Dave Marlow Multiple reports on controls for reducing worker exposures to asphalt fume Improved understanding of exposures and exposure controls for asphalt fume Analysis of Silica Polymorphs Project Officer: Rosa Key-Schwartz Standard Reference Materials SRMs for silica alpha-quartz and cristobalite were deposited onto filters for working standards through contract.
The protocol used for deposition may be used in the future for a more precise generation of Proficiency Analytical Testing PAT samples. Generation of alpha-quartz SRMs were used to compare the U.
Harmonization may be possible since the calibration curves were equivalent when the bulks were passed through a cyclone to correct for particle size differences. A detailed analysis of those laboratories resulted in several publications which listed recommendations for standard laboratory practices. OSHA rule making on the silica standard is considering incorporating these standard practices as part of an appendix.

Provided control and respiratory protection recommendations to flavorings plant operators. Initiated work with flavoring and food scientists regarding alternative flavoring formulations powders vs. Dee Cress Applied aerosol characterization and control technologies for a broad range of airborne hazards including molds, asbestos-contaminated vermiculite, wood dusts, Mycobacterium bovis, beryllium, and food flavorings.
Evaluated and demonstrated the efficacy of field use of laser-induced-breakdown spectroscopy for realtime detection of beryllium. Kay Kreiss Contributed to the development of new aerosol exposure assessment methods and standards, including instrumentation for homeland security. Christine Schuler Conducted exposure assessment and epidemiology studies to identify work processes that convey risks for the development of beryllium sensitization and chronic beryllium disease.
Proposed that bioavailability of inhaled and deposited particles rather than simple airborne mass exposure could be the appropriate metric for aerosol inhalation risks for beryllium. Recommended that workers should be protected from dermal exposures to beryllium, in addition to traditional emphasis on protection from inhalation exposures.
Prepared a report on relationships between settled dust samples, air samples and health outcomes. Prepared a report on the estimated number of workers who may be exposed to beryllium in the primary and downstream beryllium industries to provide an improved basis for protecting workers from exposure to beryllium.
Developed a comprehensive plan for evaluating worker exposures to beryllium aerosols and particles. Bean Chen A microbial assay was developed for detecting airborne fungi. It has sensitivity of detecting spores and specificity of amplifying only target fungi without cross-amplification with non-fungal DNA. Effect of dusts on the PCR method was investigated. Results indicate that inhibition varies with the type and amount of dusts. Minimal interference was detected for samples collected from personal samplers.
A personal sampler was developed for bioaerosol screening using PCR. Martin Harper A project is being prepared to investigate the formation of secondary organic aerosol in indoor air through the interaction of ozone and organic vapors. A project is being prepared to investigate inhalable samplers for wood-dust.
David Frazer Developed a system which measures the air flow and aerosol size distribution expelled during a cough. Measured air flows and aerosol size distributions from healthy volunteers during coughs.
Developed a computational fluid dynamics CFD model to examine how aerosols are dispersed during a cough. Communication interventions were produced in collaboration with an allied program project.

Internal research can include looking at: Advantages of internal research Internal research can benefit your business in several areas, such as: Costs - hiring external researchers is often more expensive than using your existing employees.
Keeping the tasks in-house also means you can control and monitor expenses and resources better. Flexibility - internal teams can be more agile when carrying out research. They can also adapt quicker to the specific or changing needs of the business.
Security - keeping research in-house can help prevent leakage of information or intellectual property outside of the organisation. Disadvantages of internal research One of the biggest downsides of internal research is the potential lack of specialisation.
(A) Internal Sources: These refer to the sources of information within the organisation. In certain cases internal sources are indispensable without which the researcher cannot obtain desired results.
Research Resources The Emory University Department of Medicine Office of Research offers internal faculty members and trainees various resources, programs, tips .
Internal research and development You can carry out your own research and development (R&D) in-house. If you do not have the resources, you could consider outsourcing to external contractors. Relying on internal staff may cause survey question bias and inadequate customer satisfaction research. Disadvantage: Resources External marketing research firms may have access to proprietary software, research pools and expert analysis not available within the company.

EMU Research Internal Research Internal research funding supports faculty research, creative, and scholarly endeavors; promotes the University’s research profile and prestige in the community; and is a valuable means of leveraging external support.
