Simple chamber facilitates chemiluminescent detection of bacteria

Test chamber enables rapid estimation of bacteria in a test sample through the reaction of luminol and an oxidant with the cytochrome C portion of certain species of bacteria. Intensity of the light emitted in the reaction is a function of the specific bacteria in the test sample

Sandwich Generation Caregivers: Ethical Legacies Throughout Generations

Research Topic This critical hermeneutic research study explores ethical meanings during a time of dual-generation care and how these interpretations may affect one\u27s view of family life across generations. The research participants in this study were adults situated between young children and dependent elders, who are also termed the sandwich generation (Brody 1981; Soldo 1996). By reexamining notions of self and others through narrative, one may see life anew from an ontological perspective not considered beforehand. Through narrative about moments of familial care, new understandings about personal meanings emerge which may or may not have changed over time. From this study\u27s conversations, participants came to see how carrying out an ethical life may be seen as part of a broader family legacy, influenced by their ethnic background, culture, faith tradition, or entirely new personal interpretations. Theory and Protocol Critical hermeneutic theory of Paul Ricoeur (1984; 1988; 1992; 2005) formed the basis of the theory applied to this study with emphasis upon areas related to temporality, ethics, and recognition. This field research followed an interpretive anthropological approach outlined by Herda (1999) that includes protocol for the study\u27s data analysis using three theoretical categories used to bring forth findings and implications. Research Categories In this study, guiding questions related to three critical hermeneutic categories brought forth data for analysis. The mimesis category fostered remembrances of the family from the past, as well as present actions, and future hopes. The theory area of ethical aim drew data about how one\u27s key ethics may influence actions of care, whether with children or elders. The final category, recognition, created or renewed the caregivers respect for their role, and that of others in society with a similar plight. Findings Caregivers recounted stories and were often unaware of the underlying ethics that informed their actions. The telling of their story with distance and proximity of their lived experience enabled the caregivers to reinterpret their own notion of a good life. The following findings came forth from participant conversations: (1) Caregiving often means retracing the past in the present; actions of care are part of a larger pattern a family passes on; (2) Caregivers may be able to move from overwhelmed to seeing new capabilities; and (3) Recognition and support for caregivers helps multi-generational families. Moments of dual-generation care may be challenging, yet may also render new interpretations of ethics that offer resilience in difficult times

The Commercial Application of Missile/Space Technology, Parts 1 and 2

This report is concerned with the transfer of technology from missile and space programs to non-missile/space applications in the United States. It presents the findings of a University of Denver Research Institute study sponsored by a National Aeronautics and Space Administration (NASA) grant awarded in November 1961. Initial stimulation for the unsolicited proposal leading to this study came from a 1960 Brookings Institution report to NASA, Proposed Studies on the Implications of Peaceful Space Activities for Human Affairs

Color Photography — Methods and Applications in Biology

Color photography by the screen-plate method belongs to the additive processes. The principle is based upon the fact that all color variations can be obtained by the mixing of the three primary colors - red, green and blue. It is not the purpose of this paper, however, to present a discussion of various screen-plates, but rather to show some of the results which may be obtained by the use of such media
