    Initiating research with doubly vulnerable populations (1999)

    Notes: Initiating research with doubly vulnerable populations Some research questions can only be answered by members of a vulnerable group. Frequently members of these groups are doubly vulnerable as they experience more than one factor that diminishes their autonomy. Initiating research with doubly vulnerable persons presents unique and often difficult challenges. Because of these challenges, many researchers purposefully exclude doubly vulnerable groups from research endeavours. Thus, the health care needs and concerns of individuals considered doubly vulnerable are often not addressed in the scientific literature. This article presents two challenges frequently encountered when initiating research with doubly vulnerable populations: resolving pre-investigation issues and gaining access to vulnerable populations. Ethically sound strategies for confronting these challenges are discussed. Researchers’ experiences with doubly vulnerable populations are also incorporated. Only when doubly vulnerable groups receive the appropriate research attention are the standards of their care and their quality of life enhanced.

    Older men's experiences of living with severe visual impairment (2003)
    Oxford, UK : Blackwell Science Ltd

    Notes: Background.  Little is known about how men react to their health and illness experiences. Lack of information about the lives of older men is unfortunate considering the anticipated growth of the older male sector of society and the fact that older men age differently than older women. One health-related experience common to many older men is severe visual impairment caused by macular degeneration, a chronic eye disease that affects central vision. Understanding the health experiences of older men is imperative if nurses are to provide quality care to this growing segment of society.Aim.  The purpose of this study was to gain an understanding of the experience of severe visual impairment from the perspective of older men with macular degeneration.Method.  A phenomenological approach was used to investigate the experience of severe visual impairment in eight older men with macular degeneration. Data were gathered through audiotaped interviews and analysed using a modified Giorgi method.Findings.  The resultant general structural description revealed six central themes: (1) older men's lives were circumscribed by what they could and could not see and could and could not do, (2) cherishing of independence, (3) creation of strategies, (4) acknowledgment of the progression of visual impairment, (5) confrontation of uncertainties, scepticisms, and fears about their diagnosis and treatment, and (6) persistence with hope and optimism.Conclusions.  A thorough nursing history and assessment must be completed, including information about the progression of the visual impairment, strategies used for living with visual loss, and presence of other health problems that may complicate life with visual impairment. Nurses must be aware that older men with macular degeneration are often sceptical about their diagnosis and treatment. Therefore, careful education and clear communication are essential.

    Comparison of the effects of filtration and preservation methods on analyses for strontium-90 in ground water (1992)
    Springer
    Environmental monitoring and assessment 20 (1992), S. 67-80

    ISSN: 1573-2959
    Source: Springer Online Journal Archives 1860-2000

    Notes: Abstract From 1952 to 1988, about 140 curies of strontium-90 were discharged in liquid waste to disposal ponds and wells at the INEL (Idaho National Engineering Laboratory). Water from four wells was sampled as part of the U.S. Geological Survey's quality-assurance program to evaluate the effects of filtration and preservation methods on strontium-90 concentrations in ground water at the INEL. Water from each well was filtered through either a 0.45- or a 0.1-micrometer membrane filter; unfiltered samples also were collected. Two sets of filtered and two sets of unfiltered water samples were collected at each well. One of the two sets of water samples was field acidified. Strontium-90 concentrations ranged from below the reporting level to 52±4 picocuries per liter. Descriptive statistics were used to determine reproducibility of the analytical results for strontium-90 concentrations in water from each well. Comparisons were made with unfiltered, acidified samples at each well. Analytical results for strontium-90 concentrations in water from well 88 were not in statistical agreement between the unfiltered, acidified sample and the filtered (0.45 micrometer), acidified sample. The strontium-90 concentration for water from well 88 was less than the reporting level. For water from wells with strontium-90 concentrations at or above the reporting level, 94 percent or more of the strontium-90 is in true solution or in colloidal particles smaller than 0.1 micrometer. These results suggest that changes in filtration and preservation methods used for sample collection do not significantly affect reproducibility of strontium-90 analyses in ground water at the INEL.

    The linear 20 kb mitochondrial genome of Pandorina morum (Volvocaceae, Chlorophyta) (1989)

    Notes: Abstract A physical restriction map of the mitochondrial genome from one clone (TCC 854) of the sexually isolated populations (syngens) of the morphologically uniform species Pandorina morum Bory has been constructed using restriction endonucleases Ava I, Bam HI, Bgl II, Eco RI, Kpn I, and Pst I. The 20 kb linear genome can easily be separated from plastid DNA, nuclear satellite rDNA, and main band (nuclear) DNA on a Hoechst/CsCl buoyant density gradient. The Pandorina mitochondrial DNA shows sufficient similarity to the 16 kb mitochondrial genome of Chlamydomonas reinhardtii to cross-hybridize, and also hybridizes with a probe containing maize mitochondrial 18S rRNA genes. Double digests, self-probing, and Bal31 exonuclease experiments suggest that 1.8 to 3.3 kb of sequence is repeated at each end of the genome as an inverted repeat. Mitochondrial genome sizes of other P. morum syngens were found to range from ca. 20 to ca. 38 kb. The mitochondrial genome should be valuable for taxonomic studies; it can be used for comparative organellar studies; and it should be of interest to compare with that of other plant and animal mitochondrial genomes.

    Notes: Abstract A procedure for determining total uranium in urine using a pulsed-laser Kinetic Phosphorescence Analyzer (KPA) is described. The chemical procedure is simple and rapid, and the operation of the KPA is straightforward. An inter-laboratory comparison (measuring total uranium by using fused pellet fluorometry, alpha spectrometry, and the KPA) demonstrates accuracy. The detection limit for this method, of 0.06 ng/mL, is readily achieved. The relative standard deviation (RSD) of the measurements at the 1.0 ng/mL level is 5%. Interference studies, which include selected elements found in urine, are discussed. Potential interferences in other matrices such as soil, milk, and water are also examined.
