Microbiological quality control of a cage washing machine by means of a thin film culture system (PetrifilmTM)

Washing machine effectiveness is dependent on treatment of cage surface with hot water containing detergent. The temperature of the washing chamber will not reflect the degree of treatment of each individual cage. Bacteriological testing ofcage surface will give a true indication of residual contamination. This study describes the use of rehydratable contact films to harvest and culture residual bacteria. The method registers numbers of colonies retrieved from the surface. It does nottype the bacteria and is as such a non-specific method. The study reveals that the machine in question was effective and that no bacteria were found following a normal cycle. A machine breakdown was demonstrated before the mechanicalcause was uncovered

Equipping Faculty of Color: Mentorship and Strategies for Success in the Academy

Equity is salient in the academy; however, the lens is focused on students and not faculty. Affording faculty of color, the same respect, honor, and opportunities white individual possess are critical. Discounting credit and recognizing individuals’ achievements based on the color of their skin transpired unfortunately. Emphasis has been provided necessitating the need to have diverse leadership in higher education to reflect the population of students. This exemplifies what students have voiced and provides support for the growing diverse population matriculating through higher education. Ensuring that recruitment for faculty of color and ongoing support is extended is paramount. Removing gaps and setting all individuals up for success is necessary

Using Doctoral Education and Research-Based Learning to Advance the Nurse Leader

Nurse leaders perform in highly autonomous positions in two dimensions; academia, and the clinical setting with the awesome responsibility to serve and protect others. To guide nursing practice, research-based skills are crucial to ensure leadership decisions are founded in evidence-based practice. Random controlled studies are gold-standard in healthcare compared to correlation or descriptive studies and employ a systematic review to strengthen findings (Schmidt & Brown, 2021). Research skills are prominent in numerous components of the leadership scope to perform at a stellar level

Educating for a Hope-Filled Future

This paper illustrates one student’s experience finding ways to pursue sustainability in a course on political narrative. The student created his own narrative for political and social change based on issues he was already deeply invested in. Tai Chi, practiced at the start of each class, facilitated this narrative creation

The optimisation of stochastic grammars to enable cost-effective probabilistic structural testing

Abstract The effectiveness of statistical testing, a probabilistic structural testing strategy, depends on the characteristics of the probability distribution from which test inputs are sampled. Metaheuristic search has been shown to be a practical method of optimising the characteristics of such distributions. However, the applicability of the existing search-based algorithm is limited by the requirement that the software’s inputs must be a fixed number of ordinal values. In this paper we propose a new algorithm that relaxes this limitation and so permits the derivation of probability distributions for a much wider range of software. The representation used by the new algorithm is based on a stochastic grammar supplemented with two novel features: conditional production weights and the dynamic partitioning of ordinal ranges. We demonstrate empirically that a search algorithm using this representation can optimise probability distributions over complex input domains and thereby enable cost-effective statistical testing, and that the use of both conditional production weights and dynamic partitioning can be beneficial to the search process

Trends in childhood type 1 diabetes incidence in France, 2010 - 2015

AIMS: To estimate type 1 diabetes incidence in children in France and its evolution between 2010 and 2015, based on comprehensive medico-administrative databases. METHODS: The algorithm built to identify new cases of type 1 diabetes selected children aged between 6 months and 14 years who had at least one hospital stay for diabetes, followed by their first insulin treatment, excluding children suffering from another form of diabetes. Age and sex specific annual incidence rates were estimated and time trend was analyzed using Poisson regression. RESULTS: A total of 12 067 children were identified as newly diagnosed with type 1 diabetes and the annual incidence rates increased between 2010 and 2015 (from 15.4 [95% Confidence Interval: 14.7;16.1] to 19.1 [18.3;19.9] per 100 000 person-years), among boys and girls, and in each age group (4 and under, 5 - 9, 10 - 14 year olds). The annual rate of increase was 4.0% [3.4;4.6]. This trend was not significantly different between each gender, and each age group. CONCLUSIONS: Valid database information on disease incidence is essential for healthcare planning and provides a valuable resource for health research. An increase of the incidence rate of type 1 diabetes in children was highlighted in both sexes and in all age groups

Revisiting the S-matrix approach to the open superstring low energy effective lagrangian

The conventional S-matrix approach to the (tree level) open string low energy effective lagrangian assumes that, in order to obtain all its bosonic ${\alpha'}^N$ order terms, it is necessary to know the open string (tree level) $(N+2)$-point amplitude of massless bosons, at least expanded at that order in $\alpha'$. In this work we clarify that the previous claim is indeed valid for the bosonic open string, but for the supersymmetric one the situation is much more better than that: there are constraints in the kinematical bosonic terms of the amplitude (probably due to Spacetime Supersymmetry) such that a much lower open superstring $n$-point amplitude is needed to find all the ${\alpha'}^N$ order terms. In this `revisited' S-matrix approach we have checked that, at least up to ${\alpha'}^4$ order, using these kinematical constraints and only the known open superstring 4-point amplitude, it is possible to determine all the bosonic terms of the low energy effective lagrangian. The sort of results that we obtain seem to agree completely with the ones achieved by the method of BPS configurations, proposed about ten years ago. By means of the KLT relations, our results can be mapped to the NS-NS sector of the low energy effective lagrangian of the type II string theories implying that there one can also find kinematical constraints in the $N$-point amplitudes and that important informations can be inferred, at least up to ${\alpha'}^4$ order, by only using the (tree level) 4-point amplitude.Comment: 34 pages, 3 figure, Submitted on Aug 4, 2012, Published on Oct 15, 201

Catheter-related bacteremia due to Kocuria rosea in a patient undergoing peripheral blood stem cell transplantation

BACKGROUND: Micrococcus species may cause intracranial abscesses, meningitis, pneumonia, and septic arthritis in immunosuppressed or immunocompetent hosts. In addition, strains identified as Micrococcus spp. have been reported recently in infections associated with indwelling intravenous lines, continuous ambulatory peritoneal dialysis fluids, ventricular shunts and prosthetic valves. CASE PRESENTATION: We report on the first case of a catheter-related bacteremia caused by Kocuria rosea, a gram-positive microorganism belonging to the family Micrococcaceae, in a 39-year-old man undergoing peripheral blood stem cell transplantation due to relapsed Hodgkin disease. This uncommon pathogen may cause opportunistic infections in immunocompromised patients. CONCLUSIONS: This report presents a case of Kocuria rosea catheter related bacteremia after stem cell transplantation successfully treated with vancomycin and by catheter removal

: Familias populares e institução escolar : entre autonomia e heteronomia

Version française de "Familias populares e institução escolar : entre autonomia e heteronomia", Educação e Pesquisa, 2010, vol. 36, n°espcial, p. 65-76International audienceL'article se propose d'analyser quelques problèmes théoriques dans l'étude des relations entre familles populaires et école, problèmes qui sont ceux que rencontre la sociologie dans l'étude des classes populaires et de leurs relations avec le monde dominant et les institutions. Il explore la possibilité de dépasser l'alternative entre une perspective strictement légitimiste qui tend à réduire les classes populaires et leurs pratiques au rapport de domination qui les aliène (hétéronomie) et la perspective relativiste qui les envisage dans une altérité radicale (autonomie) en occultant les rapports sociaux de domination. Il insiste sur l'ambivalence des logiques et des pratiques des familles populaire
