An Ergonomic Job Analysis Of A Work Process Within A Glovebox, Tamara Mcnair

Theses

Gloveboxes have been used in various industries to protect the user and environment from hazardous materials and/or isolate the materials from environmental contamination. As the use of gloveboxes continues to grow in an effort to reduce contamination and the dependency of personal protective equipment as well as increase the level of safety through containment, technical design specifications have been studied and investigated to great lengths. Unfortunately, ergonomic design criteria for this enclosed and restricting workstation have not been extensively investigated or documented.

This research evaluated ergonomic risk factors associated with the use of a glovebox in a pharmaceutical production facility. …

Effect Of Glove Port Height On Upper Body Stress For Performing Laboratory Work, Jason Mark Williams

Theses

Glove boxes are used in many industries to constrain environmental contamination and protect the worker from harmful or hazardous exposures. This research specifically evaluates the effect of height of the glove box arm ports on the efficiency of task performance and physiological costs of work for the glove box users.

Seven male and two female participants performed liquid mixing and vial filling tasks within a portable glove box. The tasks were designed to simulate common glove box tasks performed in pharmaceutical and laboratory settings. Each participant repeated the designed tasks while the glove port height was set at two different …

Do Industrial Back Support Belts Reduce Stress In Asymmetric Lifting?, Ryan Jamor Brown

Theses

The objective of this research is to determine the effects of wearing a back support belt during repetitive asymmetric lifting in terms of heart rate, blood pressure, static lift capacity, body discomfort rating and subjective rating concerning the effectiveness of a back support belt. The type of belt used in this study was of knit nylon and elastic construction designed for industrial use.

Eight female participants lifted a crate from the table to knuckle height at a rate of three lifts per minute for a period of 20 minutes; one set with wearing back support belt and one without back …

The Analysis And Characterisation Of Rotavirus And Norovirus Circulating In The South Of Ireland, Norma Reidy

Theses

On average more than 3,000 cases of rotavirus diarrhea are detected annually amongst Irish children less than 3 years of age. Rotavirus disease occurs mainly during the winter months, with peak infections detected from February to April. The symptoms of disease are diarrhea and dehydration, with 80% of patients requiring hospitalisation, The mean duration of hospitalisation is 3-4 days, with an average cost per day of €409. Eighteen percent of infections were detected in infants less than 6 months of age, suggesting inadequate maternal derived protection from existing strains, or the existence of novel strains in Ireland with little or …

Molecular Epidemiology Of Antibiotic Resistant Salmonella Enterica Strains From Different Animal And Human Sources In Ireland, David George Lee

Theses

In this study, 176 isolates of Salmonella were collected from different laboratories in Ireland. All isolates were confirmed to be of the genus Salmonella by performing bacteriological and biochemical tests. Briefly, all isolates were cultured onto XLD agar after which pure cultures were verified and stocked at this institute. Definitive identification was carried out using the API 20-E system and a separate urease test was also performed on all isolates. After confirmation of the genus, all isolates were prepared for antibiotic susceptibility testing and r-types were determined using sixteen antibiotics. Depending on the antibiotic resistance profiles, isolates were selected for …
