No full textPeri-Implantitis
No full textPeri-implantitis can affect the longevity of successfully integrated implants. Implant success is dependent on reducing the peri-implantitis risk or successfully managing peri-implantitis. Further understanding of peri-implantitis can be derived from its prevalence, microbial and diagnostic findings, existing therapies, and the effects of systemic health issues and medication. Based on published information: (1) peri-implantitis is higher in patients who have periodontitis or smoke as well as in implants with 5 years of function; (2) peri-implantitis microflora is different from periodontitis; (3) peri-implantitis risk is increased in patients with cardiovascular diseases and uncontrolled diabetes; (4) most reported peri-implantitis therapies may result in resolution, but the best peri-implantitis treatment is still to be determined; (5) more frequent peri-implant maintenance may reduce risk for peri-implantitis
Study of the bread baking process - II. Mathematical modelling
No full textA mathematical model of baking was set up and validated experimentally. The model describes heat and mass transport phenomena during baking of a cylindrical bread sample. The model was solved by finite difference numerical method. The model is based on the hypothesis described in a previous work (Zanoni, B., Peri, C. & Pierucci, S. (1993). J. Food Eng., 19, 383-98), that the variation in temperature and moisture of bread during baking is determined by the formation of an evaporation front at 100°C. The progressive advancing of the evaporation front towards the inside of the product determines different conditions of heat and mass transport in a crust and crumb portion. The validation shows that the model correctly simulates heat and mass transfer during baking. © 1994
Peri-urbanisation, Social Heterogeneity and Ecological Simplification
No full textPeri-urban development pressure on and near Australian coastlines is resulting in the conversion of agricultural land for rural-residential use. The impact of larger and more diverse human populations upon the ecological assets remaining in agricultural landscapes has consequently become a policy concern. This paper contributes to these policy debates by integrating the results of parallel social and ecological research projects commissioned to improve natural resource management in peri-urbanising regions. The research was undertaken in the case study region of South East Queensland, the region supporting Australia’s most rapid population growth. Our results indicate that both social and ecological communities cross a fragmentation threshold due to peri-urban development whereby they become ecologically simple and socially heterogeneous in a coupling that cedes a poor diagnosis for biodiversity retention.stored soil water, dryland grain cropping, extension, social systems, RD&E, differentiation
Indicadores de risco para a peri-implantite
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde, Programa de Pós-Graduação em Odontologia, Florianópolis, 2014.O objetivo deste estudo foi identificar os indicadores de risco sistêmicos e locais associados com a peri-implantite e sua prevalência. Os critérios de inclusão para o estudo compreenderam: pacientes tratados com implantes de titânio Implacil De Bortoli (São Paulo, Brasil) na Fundação para o Desenvolvimento Científico e Tecnológico da Odontologia (FUNDECTO), da Universidade de São Paulo (USP), no período de 1998 a 2012. Foram examinados 183 pacientes, reabilitados com 916 implantes em função por pelo menos 1 ano. As variáveis foram avaliadas segundo condição sistêmica do paciente, características do implante, coroa protética e parâmetros clínicos. A regressão logística não demonstrou associação de características do implante com a PI. Houve correlação estatística positiva para histórico de doença periodontal (DP), próteses cimentadas, presença de facetas de desgaste na coroa protética e próteses totais. A PI apresentou risco aumentado em 2.20 vezes para histórico de DP, 3.62 vezes para próteses cimentadas em relação às parafusadas, 2.43 vezes na presença de facetas de desgaste na coroa protética e 16.11 vezes para próteses totais em relação as parafusadas. Foram relacionados como indicadores de risco para a PI histórico de DP, próteses cimentadas, presença de facetas de desgaste na coroa protética e próteses totais. As características dos implantes não foram relacionadas com a PI.Abstract : The aim of this study was to identify systemic and local risk indicators associated with peri-implantitis (PI) and its prevalence. Inclusion criteria for the study were patients treated with osseointegrated implants (Implacil De Bortoli, Sao Paulo, Brazil) at FUNDECTO (University of Sao Paulo, USP), from 1998 to 2012. There were examined 183 patients, rehabilitated with 916 implants in function for 1 year at least. Variables were evaluated according to patient's systemic condition, implant's characteristics, prosthetic crown and clinical parameters. Logistic regression did not show any association between implant's characteristics with PI. Also, it was identified an increased risk of 2.20 times for historic of periodontal disease (PD), 3.62 times for cemented restorations compared to screw-retained, 2.43 times when displayed wear facets on the prosthetic crown and 16.11 times for total rehabilitations when compared to single rehabilitations. There were related as risk indicators for PI the historic of periodontal disease, cemented prostheses, presence of wear facets on the prosthetic crown and in total rehabilitations. Implants' characteristics were not related with PI

A Review of whether peri-operative nursing records used in the Western Cape Metropolitan health region are in line with international standards and recommendations for standard content and design characteristics for the Western Cape
No full textBibliography: leaves 180-193.Peri-operative nursing is faced with increasing pressure to improve productivity while coping with diminishing resources. Nurses have to work harder and faster while still maintaining a high standard of patient care. This emphasises the need for comprehensive, yet easy-to-use peri-operative nursing records. A descriptive, non experimental research design was used to survey peri-operative nursing records used in the Western Cape Metropolitan Health Region and content and design characteristics were identified. A comparison was made between these records and the standard set by the Association of Operating Room Nurses (AORN) in the United States of America. The criteria stipulated by the AORN standard were found to be relevant to South African peri-operative nursing practice with a few exceptions. In spite of this, the perioperative nursing records reviewed did not compare well with the AORN standard and were particularly deficient in risk management areas such as potential injury related to positioning the patient, and electrical and physical hazards. Content criteria not mentioned by the standard, but appearing in the local records were identified and certain aspects of design recognised in the literature were also discussed. Recommendations for a South African standard for peri-operative nursing records were made, as well a$ recommendations for further research into the use and design of peri-operative nursing records
Horse keeping in peri-urban areas
No full textThe number of horses in Sweden has increased from 70 000 to almost 300 000 in 30 years. Today these horses are to a large extent kept for the purpose of hobby and leisure and create a substantial land use but link a diverse and a large amount of activities in peri-urban areas in Sweden. The sector contributes with new economic, social and physical possibilities, but also with conflicts between various stakeholders and interests. The overall aim of this work was to contribute to increased understanding of the new and diverse equine sector as a factor for peri-urban landscape development, with stakeholders’ as well as public perspectives. Specific objectives were to map out the influence of the equine sector on the development of multifunctional land use in peri-urban areas and to analyze stakeholder experiences and attitudes towards horse keeping as a land use. Further to outline specific features of horse keeping in peri-urban areas as a new and expanding area of research and to determine the significance of the issue within the broader context of land use and spatial planning. The thesis focuses two issues connected to the Swedish context; set back distances between residential areas and horse keeping and the right of public access. Methods used were questionnaire studies, interviews, participatory observations and studies of media reports. The overall results show a substantial land use not well described by current methods for analyzing and managing land use change. The results from the Swedish issues set back distances between residential areas and horse keeping and the right of public access illustrates both in different ways the partly problematic meeting between the current system for spatial planning and the emerging equine sector as a new land use with conflicts both between involved stake holders and also within the planning system itself. In conclusion a need for spatial planning with both a top down and a bottom up perspective is pointed out for managing this sector allowing it to take place at a local as well as at a regional and national level
A review of policies and strategies affecting the peri-urban interface
No full textAs discussed elsewhere (Adell, 1999; Allen, 1999), whilst there is no accepted definition of what precisely constitutes the "peri-urban interface", the project team has identified at least three different approaches from where it has been conventionally conceptualised. These approaches may be classified according to the set of variables they choose to emphasise: physical attributes, such as proximity to the city and poor infrastructure; socio-economic variables; or urban-rural flows (of people, energy, goods)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
